Description

Magnetic lock, magnetic key and combination thereof

The present application relates to a magnetic lock, a magnetic key and a matching combination of a magnetic lock and a magnetic key as shown in EP1 355 550.

The present application provides a contrast structurally simplified and easier to use magnetic lock.

The application relates to a magnetic lock with at least one latch, which can be designed as a driver with a locking plate. The bolt has a first magnet and this can be moved back and forth between a locking position and an unlocking position, so that in the locking position the bolt at least partially or completely closes a receiving opening for a locking element designed in particular as a shaft. In addition, a second magnet is provided in the magnetic lock, wherein the first magnet and the second magnet exert a force on each other. In this case, preferably permanent magnets are used, but there are also magnetizable materials used as a magnet, if the same effect is achieved with these. Advantageously, the bolt is pulled together with the magnet due to this force in the locking position. This results in a space-saving and safe execution of the magnetic lock. Not only a dynamic pulling is included, but also a static holding the bolt or driver.

Instead of attracting magnets, these can also be arranged so that they repel each other. Then, however, there is a much larger footprint in many cases.

In a further embodiment, in the magnetic lock, a first latch and a second latch, ie also driver provided with a respective latch plate, wherein the first latch has at least one first magnet and wherein the second Latch has the second magnet. The first latch and the second latch are reciprocable between a locking position and an unlocking position, so that in the locking position of the first latch and the second latch or its locking plates a receiving opening for the locking element or for the shaft at least partially or completely close. This design is particularly safe and reliable in operation, because an opening and closing of the magnetic lock is made possible with very small footprint. With two bars or drivers, these can namely linearly between the locking position and an unlocked position are reciprocated, while in the embodiment only with a single bolt or driver this is often performed rotatably with a joint. This rotatable arrangement must then be carried out so that the receiving opening for a locking element in the open position of the lock is fully released as possible, if a reliable function is to be ensured. In addition, a locking of the locking plates on the full surface of the groove of a locking element or a base is made possible.

Advantageously, the first driver and the second driver move into the locking position by the first magnet and by the second magnet. Although additional spring elements or rubber elements are then possible, these are not absolutely necessary for a good closure. The first latch can also have two first magnets, while the second latch has two second magnets, wherein in each case a first magnet and a second magnet exert a force on each other. This favors a reliable handling of the magnetic lock.

The bolt or driver can rotate freely in the magnetic lock or they can also be secured by a lock contour, for example in a form as a bridge in the magnetic lock and a bolt contour as Mitnehmerkontur or as a contour in the driver against rotation relative to the magnetic lock when the lock contour engages accordingly in the bolt contour. The application provides in one embodiment in an upper part before a conical recess. In a lower part, a tilting groove is provided, wherein the bolts are received in the tilting groove when the bolts are received, for example, by an external force in the recess are moved relative to the conical recess. As a result, a manipulation of the magnetic lock is prevented by the tilting groove counteracts an opening of the bolt.

The bolt may have a driver, which are made of a non-magnetic material, so you can be sure that attract only the magnet and not the drivers. This increases the reliability of the

Magnetic lock and prevents opening about with a strong magnet from the outside.

The latch may include a latch plate having metal. In connection with a driver then you need to make the driver only of a lightweight material, while the receiving opening closing latch plate, for. made of sturdy steel.

The application also includes a lock assembly having such a magnetic lock and having a latch member or socket of a conically shaped pedestal head, a circumferential pedestal groove below the pedestal head, and a pedestal shaft below the circumferential pedestal groove. The bolt or the latch engages or engage in the locking position in the circumferential base groove.

To open the lock, a magnetic key is provided with at least two key magnets arranged in a plane such that a north pole of a key magnet faces up and a north pole of another key magnet points down. This feature results from the requirement that the key magnets be between the

Lock magnets to overcome acting force, so that the driver is pulled into the open position. In a more general form are the Key magnets arranged side by side so that a north pole of a key magnet in one direction and a north pole of another key magnet is pointing in the opposite direction substantially. Thus, other designs are conceivable, to which the terms "top" and "bottom" and "arranged in a plane" do not fit directly.

It is also possible to provide four key magnets which are arranged in a plane around a center, so that in the case of key magnets facing each other with respect to the center, the same pole points upwards. This is particularly safe, because you can not or only very difficult to open by an external, not correspondingly complex poled key magnet so trained driver. Only a properly executed magnetic key opens this bar or driver.

If the key magnets are rotatably mounted on a disk about an axis of rotation, then an alignment during opening is favored.

At a supernatant on the underside of the magnetic key projections or steps may be provided which engage with recesses which on the

Top of a top of the magnetic lock are provided. This favors alignment when placing the magnetic key on a magnetic lock.

Finally, the application also includes a combination of such a magnetic key and such a magnetic lock, each one

Key magnet in the unlocked position each having a horizontal offset relative to an adjacent lock magnet, so that the key magnets are farther apart than the lock magnet, then results in a reliable opening of the lock. The same advantage results if each one key magnet in the unlocked position has a vertical offset relative to an adjacent lock magnet.

In the following description of the figures, details are given to the

Describe embodiments of the application. However, it should be apparent to one skilled in the art that the embodiments may be practiced without these details.

Figure 1 to Figure 5 show a first embodiment of a magnetic lock 20 in different views.

Figure 1 shows a cross-sectional view of the magnetic lock 20 in a locking position from the side. The magnetic lock 20 is divided into a base 22, a housing 24 and other components within the housing 24. The housing 24 has a circular opening 26 at the bottom of the housing 24. A base head 28 of the base 22 is inserted into the opening 26, so that the Base 22 is locked in the housing 24. The base 22 is best seen in Figure 3 in which the base 22 is shown completely. The base 22 has from top to bottom: a base head 28, a circumferential base groove 42, a socket shaft 80 and a base foot 82. The base shaft 80, which is formed as a straight cylinder with a constant diameter, connects the circumferential base groove 42 with the Base foot 82. The base foot 82 is formed in the form of a thin and large circular plate. The base head 28, the circumferential base groove 42, the base shaft 80 and the base foot 82 are axially aligned with their longitudinal axes, so that their longitudinal axes coincide with the longitudinal axis 30 of the housing 24. Between the base foot 82 and the lower part 32 is a bandage belt 39 with a sail lug 41 which is mounted on a bandage belt 39 for reinforcement. The bandage belt 39 and the sails 41 are clamped between the base foot and the lower part 32. The sail lug 41 surrounds the base shaft 80. This arrangement is used for fixing a person not shown here.

The housing 24 has a cylindrical upper part 25, which is executed in the direction of the bottom of the housing 24 to open. At the top of the wall of the upper part 25, a conical or conical recess 34 or receptacle is formed, which is particularly well seen in Figure 3 and Figure 4. The housing 24 further has a lower part 32, which closes the upper part 25 at its lower end. The lower part 32 and the upper part 25 form in their interior a cavity containing the other components of the magnetic lock 20. An opening 26 is located in the center of the lower part 32 and extends through the lower part 32 therethrough. Both the opening 26 and the base 22 are axially aligned with the longitudinal axis 30 of the housing 24.

The inserted into the upper part 25 lower part 32 has the shape of a solid cylinder with a circumferential shoulder 33. At the top of the lower part 32 opposite the locking plates 53, 55 a tilting groove 35 is inserted. The tilting groove 35 forms a circle which has the longitudinal axis 30 to the center and deepens from the inside out. The lower part 32 is inserted into such a wide opening of the upper part 25, that the upper part 25 is sealed. Between the upper wall of the upper part 25 and the lower part 32, a cavity is recessed. The height of the cavity is slightly larger than the height of the frustoconical base head 28 and the base groove 42. The lower part 32 is glued in the upper part 25, so that the two parts 25, 32 of the housing 2 fixed and axially along the longitudinal axis 30 of the housing 24 are aligned.

Two Magnetmitnehmer 36, 38 are provided in the cavity between the upper part 25 and the lower part 32. The two Magnetmitnehmer 36, 38 have an identical shape that resembles a crescent. This form of the magnetic driver can be seen particularly well in FIG. 2, which shows a plan view of a cross section through the magnetic lock 20 along the section line A-A in FIG. The two Magnetmitnehmer 36, 38 are slidably on an inner plane surface 201 of the lower part 32. The end faces 58, 60, 66, 68 of the crescent-shaped regions abut each other. The left magnet driver 36 is placed on the left side of the base 32 in FIG. 2, whereas the right magnet driver 38 is placed on the right side of the bottom 32. The left Magnetmitnehmer 36 and the right Magnetmitnehmer 38 are thus arranged symmetrically to the longitudinal axis 30 of the housing 24 around. The Magnetmitnehmer 36, 38 are slidable on the lower part 32. The guide web 27 in the upper part 25 engages in a contour recess 202 on the Magnetmitnehmer 36, 38 and secures the Magnetmitnehmer against rotation about the axis 30 of the magnetic lock 20. The guide web 27 is particularly well recognizable in Figures 18 to 20 and the contour recess 202nd is particularly well recognizable in Figure 21.

The two Magnetmitnehmer 36, 38 meet at their upper ends to each other but leave a gap 200 at its lower end free. This gap 200 has the profile of an inverted V, as shown in FIG. Further details of Magnetmitnehmer 36, 38 are also better seen in Figure 2. Everyone who Magnetic driver 36, 38 has two magnets and a locking plate. All four magnets are ferrite magnets or NdFeB magnets. The left Magnetmitnehmer 36 has two magnets 44, 46 above a left latch plate 53. The right Magnetmitnehmer 38 has two other magnets 48, 50 above a right latch plate 55th

The structure of the base 22 with the base head 28, which is formed as a conical truncated cone, can be seen particularly well in FIG. A front end of the socket 22 has a reduced diameter as compared with the socket diameter of the socket 22. Under the base head 28, a circumferential base groove 42 is disposed around the base 22 around. Parts of the two Magnetmitnehmer 36, 38 are above the locking plates 53, 55 at the circumferential base groove 42 of the base 22 at.

FIG. 2 shows a plan view of the magnetic lock 20, along a section line A-A in FIG. 1, so that the inner parts of the magnetic lock 20 can be seen. In the plan view, the housing 24 in the outer profile has a circular shape. In the housing 24, a vertical axis 52 and a horizontal axis 54 are drawn such that the two axes 52, 54 are perpendicular to each other, and intersect in the center of the housing 24. The projection of the longitudinal axis 30 thus coincides with the intersection of the horizontal axis 54 with the vertical axis 52. A cylindrical wall 203 of the housing 24 encloses both the Magnetmitnehmer 36, 38 and the base head 28 of the base 22. In the center of the housing 24 show two concentric circles the conical frustoconical base head 28 of the base 22. The two Magnetmitnehmer 36, 38 are close of the base 22 is arranged on the circumferential base groove 42.

The left magnet driver 36 has a left latch plate 53 and two round magnets 44, 46 on the upper plane of the left latch plate 53, namely, a left upper latch magnet 44 and a left lower latch magnet 46. The upper left latch magnet 44 and the lower left Lock magnet 46 are arranged symmetrically to the horizontal axis 54 at opposite ends of the crescent-shaped left latch plate 52 and at opposite ends of the left Magnetmitnehmers 36. A north pole of the left upper lock magnet 44 and a south pole of the left lower lock magnet 46 are directed upward.

On the left side of Magnetmitnehmers 36, the left Magnetmitnehmer 36 has an outer edge 56 which is partially circular. The outer edge 56 fits to an inner wall 205 of the upper part 25. On the right side of the left Magnetmitnehmers 36 two short left straight edges 58, 60 are arranged, each with the same length. In the middle part of the left Magnetmitnehmers 36 a left semicircular edge 62 is formed on the right, which connects the two left straight edges 58, 60 together. The two short left straight edges 58, 60 are formed by an upper left straight edge 58 at the upper end and a lower left straight edge 60 at the lower end. The two left straight edges 58, 60 are arranged symmetrically to the horizontal axis 54.

The right Magnetmitnehmer 38 is identical to the left Magnetmitnehmer 36 constructed. The right Magnetmitnehmer 38 has a right latch plate 55 and two round magnets 48, 50 at the top and at the bottom of the right latch plate 54, namely a right upper lock magnet 48 and a right lower lock magnet 50. The circular magnets 48, 50 are symmetrical to the horizontal axis 54 at opposite ends of the crescent-shaped right Magnetmitnehmers 38 arranged. A south pole of the upper right

Lock magnets 48 and a north pole of the right lower lock magnet 50 are directed upward.

On the right side of the right Magnetmitnehmers 38, the right Magnetmitnehmer 38 an outer edge 64, which is partially circular. The outer edge 64 mates with an inner wall 205 of the housing 24. On the left side of the right Magnetmitnehmers 38 two short rights are straight Edges 66, 68 arranged in each case with the same length. In the middle part of the right Magnetmitnehmers 38 a right semicircular edge 70 is arranged on the left, which connects the two short right straight edges 66, 68 together. The two short right straight edges 66, 68 are formed by an upper right straight edge 66 at the upper end and a lower right straight edge 68 at the lower end. The two right straight edges 66, 68 are also arranged symmetrically to the horizontal axis 54.

As shown in FIG. 2, in the locked position, the upper left straight edge 58 contacts the upper right straight edge 66 and the lower left straight edge 60 touches the lower right straight edge 68, respectively along the vertical axis 52 left semi-circular edge 62 and the right semicircular edge 70 in the locking position of the magnetic lock 20 of Figure 2 very close to the base head 28. The cylindrical hole formed between the left and right Magnetmitnehmer 36, 38 has a slightly larger diameter than that Pedestal köpf 28.

A circumferential arrow 43 indicates a power flow 43, which can occur when a force is exerted on the bandage belt 39 on the right side. In this case, the lower part 32 is pulled upwards so that the intermediate space between the right locking plate 55 and the base head 28 closes. The power flow 43 then passes from the bandage belt 39 via the lower part 32, the right latch plate 55, the base head 28, the socket shaft 80, the base foot 82 and the sails 41. The upper part 25 and the Magnetmitnehmer 36, 38 are not in the power flow.

For easier positioning of a magnetic key, according to a further embodiment, additional markings may optionally be provided on the outer upper end of the housing 24, as shown in FIG

Markers 72, 74, 76, 78 are an upper mark 72, a left mark 74, a lower mark 76 and a right mark 78. The upper one The mark 72 and the lower mark 76 are filled with color, and they are arranged along the vertical axis 52. In the left marker 74 and the right marker 78, the color is omitted and they are arranged along the horizontal axis 54. All four markers 72, 74, 76, 78 are disposed near the outer edge of the housing 24.

FIG. 3 shows a side view of the magnetic lock 20. In FIG. 3, the magnetic lock 20 is shown in an upright position, with the housing 24 being mounted on the upper end of the base 22. The left and right Magnetmitnehmer 36, 38 are on the latch plates 53, 55 with the circumferential base groove 42 of the base 22 into engagement and prevent removal of the magnetic lock 20 from the base 22nd

A strong magnet 84 is placed on the upper plane surface 207 of the housing 24. The magnets 44, 46, 48, 50 of Magnetmitnehmer 36, 38 are used on the magnet 84 when the magnet 84 is sufficiently strong. Thereby, the two Magnetmitnehmer 36, 38 are raised and pressed against the conical recess 34. Their boundary edges 150 can be seen particularly well in FIG. 1 and FIG. The lower ends of the Magnetmitnehmer 36, 38 come closer under the influence of any magnet 84. This closes the V-shaped gap 200 shown in Figure 1 between the Magnetmitnehmer 36, 38. The undersides of the locking plates 53, 55 and the lower outer edge of the Magnetmitnehmer 36, 38 are pressed into the tilting groove 35. An opening of the lock by any magnet is thereby prevented, even if the Magnetmitnehmer are pushed in this state by a reciprocation of the magnet 84. Namely, the outer edge of the tilting groove 35 mechanically blocks the magnetic catches 36, 38 and the latching plates 53, 55 from further moving apart. The latch plates 53, 55 in the circumferential socket groove 42 remain trapped between the socket shaft 80 and the conical frusto-conical socket head 28, so that the socket 22 can not be pulled out of the opening 26. Figure 4 and Figure 5 show the magnetic lock 20 in an unlocked position. In comparison with Figures 1 to 3, the two Magnetmitnehmer 36, 38 are further spaced from each other, because magnetic forces of a magnetic key 90, not shown here pull the Magnetmitnehmer 36, 38 apart until they rest against the inner wall 205 of the housing 24. This can be clearly seen in Figure 8, which also shows the magnetic key 90. As shown in FIGS. 4 and 5, the left inner semicircular edge 63 and the right inner semicircular edge 71 of the latch plates 53, 55 are pulled out of the circumferential socket groove 42, so that the socket 22 is pulled out of the opening 26 of the housing 24 can.

Figure 6 and Figure 7 show a first embodiment of a magnetic key 90 which is placed on the magnetic lock 20 according to Figure 4 and 5. Figure 6 shows a plan view of the lower bottom surface of the magnetic key 90 for the magnetic lock 20. The magnetic key 90 has a substantially cylindrical body 92. The magnetic key 90 further has a lid 94 with a contour 208 for gripping by hand and a flat bottom surface 96th At the bottom surface 96, an annular rim 98 projects downwards. The inner diameter of the annular wall 98 is slightly larger than the outer diameter of the housing 24. The vertical axis 52 and the horizontal axis 54 intersect at the center of the flat top surface 94, so that the flat bottom surface 96 in four equal and to the axes 52, 54th symmetrical areas is divided.

Four round magnets 99, 100, 102, 104 are arranged in a ring around a longitudinal axis of the magnetic key 90, with the same distance. The longitudinal axis of the magnetic key 90 coincides with the longitudinal axis 30 of the housing 24. All four round magnets 99, 100, 102, 104 are rare earth magnets or also NdFeB magnets or hard ferrite magnets. The four

Round magnets 99, 100, 102, 104 are fixed within the magnetic key 90. The orientations and arrangements of these round magnets 99, 100, 102, 104 are shown in Figures 6 to 8. In each case two annularly adjacent magnets have an intermediate angle α of 90 °.

As shown in FIG. 6, the two upper round magnets 99, 104 are arranged symmetrically with respect to the two lower round magnets 100, 102 with respect to the horizontal axis 54. The two left circular magnets 99, 100 are arranged symmetrically to the right circular magnets 102, 104 with respect to the vertical axis 52. The four round magnets 99, 100, 102, 104 are aligned so that two diagonally opposite circular magnets each have the same upward polarity. In the arrangement of Fig. 6, the south poles of the left lower key magnet 100 and the right upper key magnet 104 face upward and the north poles of the lower right key magnet 102 and the left upper key magnet 99 face upward.

Orientation marks 106, 108, 110, 112 of the magnetic key 90 are further distributed between the annularly adjacent magnets. The four orientation marks 106, 108, 110, 112 are uniformly distributed between four round magnets 99, 100, 102, 104. In particular, the markings 99, 100, 102, 104 are distributed along the horizontal axis 54 and the vertical axis 52 near the outer boundary of the magnetic key 90. The four round magnets 99, 100, 102, 104 are hidden within the magnetic key 90.

In the cross-sectional view of FIG. 7, the two round magnets 100, 102 arranged on the bottom surface 96 of the magnetic key 90 are visible from the side. Furthermore, a contour 208 for gripping the magnetic key 90 by hand is shown.

FIG. 8 shows a side view of the magnetic lock 20 from FIGS. 4 to 5, in the unlocked position together with the magnetic key 90 from FIG. 7 in a cross-sectional view. The magnetic lock 20 is placed directly below the magnetic key 90 so that it is received in the edge 98. The markers 106, 108, 110, 112 on the magnetic key 90 are equipped for illustration to match the markings 72, 74, 76, 78 on the magnetic lock 20. Only the two lower round magnets 46, 50 of the magnetic lock 20 are visible in FIG. FIG. 8 furthermore makes clear that the round magnets 100, 102 of the magnetic key 90 are further apart in the unlocking position than the circular magnets 46, 50 of the magnetic lock 20. This ensures that the magnetic drivers 36 are always securely tightened into the open position. By the opposite polarity of the opposite sides of the magnets 100, 46 and the magnets 102, 50 act attractive forces between the magnets 100, 46 and between the magnets 102, 50. As a result, the freely movable arranged Magnetmitnehmer 36, 38 are pulled apart. The Magnetmitnehmer 36, 38 thus move away from the base 22, so that the locking plates 53, 55 of the Magnetmitnehmer 36, 38 are also moved away from each other and moved out of the circumferential base groove 42 of the base 22. When the locking plates 53, 55 are moved out of the circumferential base groove 42, the base 22 can be pulled out of the opening 26 of the housing 24.

The magnetic lock 20 provides a simple locking device for coupling and decoupling the socket 22 with the housing 24 and the lower part 32. The magnetic lock 20 has very few components. Therefore, the magnetic lock 20 and the magnetic key 90 can be easily constructed and manufactured.

The requirements for the outer shape and the inner coupling of the magnetic lock 20 are typically in the hundredths of a millimeter tolerance range. These tolerances can be met by inexpensive injection molded parts. The cost of mass production of the magnetic lock in large numbers can therefore be kept low. The magnetic lock 20 does not require expensive components. For example, the circular magnets 44, 46, 48, 50 in the magnetic key 20 may be formed as rare earth ferrite magnets. The round magnets 44, 46, 48, 50 in the housing 24 of the magnetic lock can also be ferrite or Alnico magnets, which are also inexpensive. The upper part 25, the lower part 32, the Magnetmitnehmer 36, 38 and also the base 22 can be produced inexpensively by typical injection molding of thermoplastic materials such as polystyrene, ABS or acrylonitrile-butadiene-styrene, polyamide, polypropylene, polyethylene and polyvinyl chloride or PVC , The base can also be made of steel or other metals.

The magnets of the magnetic lock 20 and the magnetic key 90 may further comprise metallic magnetic elements, composite and rare earth magnets. Suitable composite magnets for the magnet are, for example, ceramic magnets, ferrite magnets, Alnico magnets, Ticonal magnets, Neodymium-iron-boron magnets, resin-based sphtzgussgeformte magnets, flexible resin or binder-based magnets, etc. Individual components of the magnetic lock 20 and the Magnetic key 90 may also be magnetized or made of permanent magnets according to a predetermined magnetic pattern to perform desired functions.

The magnetic lock 20 is resistant and reliable. It is unlikely that vibration or clumsiness will destroy the magnetic lock 20. These properties allow that

Magnetic lock 20 can be used in a wide range of applications, for example as a backup for bandage systems, as a bearing lock, or as a security label for garments and luggage bags.

The magnetic lock 20 can be easily integrated into other applications. For example, the housing 24 of the magnetic lock 20 may be an integral part of a door with a child safety lock. The base 22 of the magnetic lock 20th can be mounted on a frame of the door. A device with the magnetic lock 20 can be manufactured with an integrated locking function using the magnetic lock 20.

The markings 72, 74, 76, 78, 106, 108, 110, 112 on the housing 24 and the magnetic key 90 provide for easy unlocking. The indicia 72, 74, 76, 78, 106, 108, 110, 112 provide user guidance in use of the magnetic latch 20. The indicia 72, 74, 76, 78, 106, 108, 110, 112 may also be used as part of an ornament the magnetic lock 20 and the magnetic key 90 are used.

The magnetic lock 20 requires no external power supply for operation. For example, the magnetic lock 20 does not require a battery for operation, which may cause additional costs and failure due to power failure. The magnetic lock 20 is a self-contained system that can be operated independently.

Alternatively, the housing 24 may be shaped differently, such as cubic. When the housing 24 has a rectangular shaped top surface, a magnetic key that mates with the top surface can easily unlock the magnetic lock 20. In this case, the correct positioning of the magnetic key 90 on the magnetic lock 20 is facilitated by the shape of the magnetic lock 20. Other shapes in which the magnetic key 90 forms a counter-shape to the magnetic lock 20 are also possible.

According to an alternative, the circumferential base groove 42 may take on a different shape, which mates with the Magnetmitnehmer 36, 38. Instead of two Magnetmitnehmer 36, 38, a single Magnetmitnehmer be provided, for example, when the opening 26 is provided near the side wall of the housing 24. The base 22 can also be made in a different shape that can be blocked by the Magnetmitnehmer 36, 38. For example, the pedestal 22 may have a square cross section, triangular cross section, polygon, or other shape. The opening 26 can also accommodate the base with play.

The housing 24 of the magnetic lock 20 protects the Magnetmitnehmer 36, 38 from shock, corrosion and irradiation, etc. from the outside. Even if the housing 24 of the magnetic lock 20 is dropped from the height, the inner Magnetmitnehmer 36, 38 are protected against breakage and scratching.

The round magnets 44, 46, 48, 50 of the magnetic lock 20 provide driving forces for opening and closing the magnetic lock 20. If no external magnet is present, the circular magnets 44, 46, 48, 50 attract to the Magnetmitnehmer 36, 38, so that they move towards each other until they reach the locking position shown in Figure 2 and fix the base 22.

The round magnets 44, 46, 48, 50 within the housing 24 of the magnetic lock 20 are weaker magnets than the round magnets of the

Magnetic key 90. In the presence of the magnetic key 90, as shown in Figure 8, the circular magnets 44, 46, 48, 50 are used within the housing 24 to the magnets 99, 100, 102, 104 of the magnetic key 90, so that the Magnetmitnehmer 36th , 38 are moved away from each other and pulled into the unlocked position. The Magnetmitnehmer 36, 38 are moved against the cylindrical inner wall 205 of the housing 24.

The conical frusto-conical socket head 28 of the socket 22 facilitates the insertion of the socket 22 into the housing 24 of the magnetic lock 20. Since the tip of the socket 22 has a smaller diameter than the opening 26 and the hole between the abutting Magnetmitnehmer 36, 38, For example, the base 22 can be easily pushed through the opening 26 and through this hole.

The circumferential base groove 42 of the base 22 cooperates with the latch plates 53, 55 of the Magnetmitnehmer 36, 38 such that the locking plates 53, 55 prevent the base 22 from moving out of the housing 24 when the two locking plates 53, 55 are inserted into the circumferential base groove 42.

A method of manufacturing the magnetic lock includes the following steps: some of the steps may be changed in their sequence. In a first step, the housing 24 is provided. In a second step, the magnetic carriers 36, 38 are brought into the housing 24 with the magnets 44, 46, 48, 50 and the locking plates 53, 55. In a third step, the magnetic drivers 36, 38 are concealed within the housing 24 with the lower part 32. In a third step, the socket 22 may be provided.

Optionally, the magnetic lock 20, the base 22 or both can be attached to an object to be closed. The method of manufacturing the magnetic lock is easy to perform because it can do without machines for a precise operation.

A method of locking the magnetic lock 20 includes inserting the socket 22 into the opening 26. A method of unlocking the magnetic lock 20 includes engaging the magnetic key 90 with the magnetic lock 20 according to a predetermined arrangement, so that the pedestal 22 can be pulled out of the magnetic lock 20. Locking and unlocking procedures are easy to perform as no external power or complex equipment is needed.

The magnetic key 90 may have a turntable with the named circular magnet 99, 100, 102, 104, which then aligns automatically when approaching the magnetic lock by the axial magnetic force to the polarization of the circular magnet 44, 46, 48, 50 of the magnetic lock 20. Also a further embodiment could have a top 25 without guide bar 27, so that the polarization of the round magnets 44, 46, 48, 50 of the Magnetmitnehmer 36, 38 freely movable rotating to the approaching magnetic key 90, which align with the circular magnet 99, 100, 102,104 can.

It is also possible for a guide web to be located on the lower part 25 or on the magnetic catches 36, 38 to engage the magnetic catches 36, 38 and engage in an opposite contour.

FIGS. 9 to 17 show a magnetic lock 20 according to a further embodiment. Numerous parts of the magnetic lock 20 from FIG. 9 correspond to the magnetic lock of the preceding figures. Corresponding components are provided with an apostrophe. Carrier are omitted in these views.

The socket shaft 80 'of Figure 9 is fully shown in Figure 16. Below the base groove 42 'of the base shaft 80' has a cylindrical portion 118 whose diameter corresponds to the diameter of the base head 28 '. Below the cylindrical portion 118, the pedestal shaft 80 'has a ten-cornered portion 115 whose diameter is slightly larger than the diameter of the cylindrical portion, and again below the ten-edged portion 115, the pedestal shaft 80' has a lower cylindrical portion. At the lower cylindrical portion, a bottom plate 82 connects. Here, the lower cylindrical portion has a variable radius. The further construction of the base 22 'corresponds to the construction of the base of FIG. 8.

The lower part 32 'of the housing 24' shown in Fig. 9 has an opening 26 'for insertion of the base 22'. The opening 26 'has a cylindrical portion 117 and below the cylindrical portion 117 a tenkantförmigen portion 116. The cylindrical portion 118 of the base shaft 80' fits in the cylindrical portion 117 of the opening 26 '. Also fits the ten-shaped portion 115 of the base shaft 80 'in the tenkantförmigen portion 116 of the opening 26'. By the positive connection of the ten-shaped portion 115 with the tenkantförmigen recess 116, a rotation of the lower part 32 'relative to the base shaft 80 is prevented, so that the driver 36, 38 not by a rapid rotation of the lower part 32' or the associated upper part 25 'relative to the Base shaft 80 'set in rotation and can be pulled apart by the centrifugal force.

In contrast to the embodiment of Figure 1, the upper part 25 'has no

Guide bar and no roof-shaped recess. Furthermore, the lower part 32 'contains no tilting groove.

FIG. 10 shows a cross-sectional view of the upper part 25 'from FIG. 9. FIG. 10 shows a guide collar 40 which mates with the base head 28' so that it is received in a form-fitting manner, as shown in FIG. Furthermore, located on the underside of the guide collar 40 'has a radius 210. On the inner wall 205 of the upper part 25', a circumferential bevel is attached below.

FIG. 11 shows a view from below into the upper part 25 ', in which the guide collar 40', the radius 210 and the circumferential chamfer 209 are shown from below.

FIG. 12 shows a view of the lower part 32 'along the section line B-B in FIGS. 9 and 10 from below. The lower part 32 'has in the upper region a cylindrical opening 117 and in the lower region a dashed line opening 116 in the form of a regular toe.

Figure 13 shows a cross-section of the base 32 'of Figure 9. Herein, the bottom tenon-shaped opening 116 and the top circular opening 117 are shown from the side. FIGS. 14 and 15 show a section of the lower part 32 'from FIG. 13 and a base shaft 80' inserted therein. As can be seen in FIGS. 14 and 15, the gap 119 between the base shaft 80 'and the round opening 117 of the lower part 32' is made so narrow that the base shaft 80 'can tilt only slightly with respect to the axis 30. As a result, tilting of the drivers 36, 38 is prevented, so that the locking plates 53, 55 can not tilt in the circumferential base groove 42. The opening of the magnetic lock 20 with a magnetic key is thus facilitated.

Figures 16 and 17 show a socket shaft 80 'according to

Embodiment of Figures 9 to 15. Figure 16 shows a side view of the base 22 '. The socket shaft 80 'has a cylindrical portion 118 at its upper end. Subsequently, the base shaft 80 'has a ten-cornered section 117 with a ten-cornered cross-section. Below the ten-edge section of the base shaft 80 'is cylindrical and passes at its lower end in the base foot 82' on. FIG. 17 shows a cross-sectional view of the base 22 'from FIG. 16 along the cross-sectional line F-F, which illustrates the shape of the decimal section 115.

FIGS. 18 to 20 show an upper part 25 "according to another

Embodiment. Here, 25 "a guide bar 27" is attached to the underside of the upper part. This guide web 27 "prevents rotation of the drivers 36, 38 about the axis 30 of the magnetic lock 20. The guide web 27" is shown in Figure 18 in plan view. The guide web 27 "runs along the horizontal axis 54 and is interrupted by the guide collar 40. This can also be seen in the cross-sectional view of Fig. 20, in which the guide web 27" is shown from the side.

19 shows a cross-sectional view of the upper part 25 "along the line DD The cross section of the guide web 27" is indicated by a dashed line. The guide web 27 "is located in front of and behind the cross section CC of FIG. 18. Figures 21 and 22 show plan views of the drivers 36, 38 according to the first embodiment. In Fig. 21, the drivers are shown in the locking position. FIG. 21 also shows a contour 121 drawn in dashed lines on the drivers 36, 38. This contour 121 can also be seen in FIG. 2 described above. The contour 121 is formed by a raised portion 122, which is located on the outside of the top of the driver 36, 38. The raised area 122 contains a recess or depression 202 into which a guide web 27 can engage.

In Figure 22, the drivers 36, 38 are shown in the unlocked position. Dashed lines show the positions of the round magnets 44, 46, 48, 50 of the drivers 36, 38 in an unlocking position 216 and in a locking position 215. The position of the key magnets 99, 100, 102, 104 is shown by solid lines. The centers of the

Key magnets 99, 100, 102, 104 are further apart from the axis of symmetry 52 by a horizontal offset 125 than the centers of the circular magnets 44, 46, 48, 50 of the magnetic lock. Furthermore, the centers of the key magnets 99, 100, 102, 104 are farther from the symmetry axis 54 by a vertical offset 127 than the centers of the round magnets 44, 46, 48, 50 of the magnetic lock. The horizontal offset ensures a safe opening, since even in the unlocked position a lateral force on the circular magnets 44, 46, 48, 50 acts. Due to the vertical offset, a vertical force additionally acts parallel to the symmetry axis 52 on the round magnets of the lock. This vertical force contributes to vertically centering the magnet drivers 36, 38 and thus preventing tilting of the strike plates 53, 55.

Figure 23 shows one of the two identical locking plates 53, 55 in a plan view. The outline of the locking plate 53, 55 comprises an outer semicircle. In the middle of the outer semicircle a microbridge 127 is present. This microbridge 127 is formed by laser cutting through the beginning and the end of the Cutting guide in a steel sheet. It can be used to fit the locking plate 53, 55 in the associated driver 36, 38. FIG. 24 shows a cross-sectional view of the latching plate 53 from FIG. 23 along the cross-sectional line AA. Here, the microbridge 127 is visible from the side.

Figures 25 and 26 show another embodiment of an upper part 25 '' 'for a magnetic lock, in the upper part 25' 'there are four recesses 128 which allow a raised cross 129 to stand. On the underside of an associated magnetic key, which is not shown here, a cross-shaped web is provided, which fits into the depressions 128 of the upper part 25 "', which enables a secure positioning of the magnetic key on the upper part 25'". In the embodiment of Figures 25 and 26, the drivers and the magnets of the magnetic lock do not need to be freely rotatable, since the correct positioning of the magnets can be ensured by the orientation of the magnetic key here.

Figures 27 and 28 show a further embodiment of a magnetic key 90 'for a magnetic lock 20. Here, the magnets 99', 100 ', 102', 104 'of the magnetic key are rotatably mounted on a turntable. This can be seen in FIG. 28. In contrast, the position of the driver in

Magnetic lock secured against rotation, for example, by the guide web 27 shown in Figures 1 to 5 and in Figures 16 to 18.

Figure 27 shows the external shape of the magnetic key 90 '. The magnetic key 90 'has an elongated, teardrop-shaped shape with a flat, circular bottom surface 130. In this teardrop-shaped form, three recessed grips 131 are provided, which serve for detecting the magnetic key with thumb, index and middle fingers. On the bottom surface 130 on the underside of the magnetic key is a circular projection 132. The radius of the circular projection is dimensioned so that the circular projection fits on the upper part 25 of the magnetic lock 20. The circular projection 132 has three symmetrically mounted steps 133. The steps 133 improve the placement of the magnetic key and also serve for easier optical detection. In the center of the bottom surface 130, a bore 134 is provided for receiving an axle bolt 135, which is shown in FIG.

FIG. 28 shows further details of the magnetic key of FIG. 27 in a cross-sectional view. As shown in Figure 28, the axle pin 135 has a collar in the form of a step 136. Between the pivot pin 135 and the bottom surface 130 is a turntable 137 in the form of an annular driver, in which the magnets of the magnetic lock 98 ', 99', 100th ', 102' are inserted. By the step 136 of the axle pin 135, the turntable 137 is rotatably held from below. When placing the turntable 137 on the axle pin 135, the magnets 99 ', 100', 102 ', 104' of the magnetic key automatically align with the magnets of the magnetic lock 20 '.

FIG. 29 shows a cross section of the magnetic key on FIG. 28 along the cross-sectional line H-H. In this case, the steps 133 in the projection 132 can be seen in cross section.

FIG. 30 shows a schematic cross section through a variant of an upper part 25 of a further magnetic lock. The upper part 25 contains

Recesses 210 which mate with the steps 133 of the magnetic key of FIG. This ensures a secure placement of the magnetic key.

FIG. 31 shows a plan view of an erosion structure 213 for an upper part 25 of a further magnetic lock. On the upper side of the magnetic lock two polished surfaces 211, 212 are provided. The polished surface 211 is parallel and laterally offset from an axis of symmetry 52. The polished surface 212 is symmetrical about a symmetrical axis 54 perpendicular thereto. In the polished surface 212, a brand name is attached. The brand name is clearly visible from above and protected by the recess 212. In the following, the operation of a magnetic key according to the application for opening a magnetic lock according to the application will be explained. There are various alternatives according to the application. According to a first alternative, the lock magnets can be guided by a guide device, as shown in FIGS. 1 to 5 or in FIGS. 18 to 20, and the key magnets can be fixedly arranged in the key, as shown in FIGS. 6 and 7. According to a second alternative, the Magnetmitnehmer 36, 38 may be freely rotatably arranged, as shown in Fig. 9 to 17 and the key magnets are arranged firmly in the key. According to a third

Alternatively, the lock magnets may be guided by a guide means and the key magnets may be arranged on a turntable, as shown in Figs. 27, 28. The explanations in connection with FIGS. 21, 22 with respect to the offsets 125, 217 of the key magnets to the lock magnets apply mutatis mutandis to all alternatives.

The operation of a magnetic key according to the first alternative has been explained above with reference to FIG. In this case, the correct placement position can be found by sensing the force effect or by aligning the markings. In addition to these two options or as an alternative to the markings, a positive connection between the magnetic key and the magnetic lock is also possible, as explained for the magnetic lock of FIGS. 27-30. This determines the correct placement position.

When placing a magnetic key according to Figure 27 - 29, the steps 133 of the magnetic key 90 'are inserted into the recesses 210 on the upper part 25 of the magnetic lock 20. Due to the magnetic attraction between the key magnets 99 ', 100', 102 ', 104' and the lock magnets 44, 46, 48, 50, the turntable 137 of the magnetic key 90 'rotates, so that the key magnets 99', 100 ', 102 , 104 'align with the lock magnets 44, 46, 48, 50 so that opposite poles face each other. Continue to be the lock magnets 44, 46, 48, 50 pulled by the key magnets 99 ', 100', 102 ', 104' in the unlocked position, as described in Fig. 8.

When placing a magnetic key on a magnetic lock according to Figure 9 to 17, the lock magnets 44, 46, 48, 50, the freely rotatably arranged Magnetmitnehmer 36, 38 to the key magnets 99, 100, 102, 104 from that opposite to opposite poles. Furthermore, the lock magnets 44, 46, 48, 50 are pulled by the key magnets 99 ', 100', 102 ', 104' in the unlocked position, as described in Fig. 8. This is because the attractive force acting between the lock magnets 44, 46, 48, 50 and the key magnets 99 ', 100', 102 ', 104' in the aligned position is just slightly larger than that under the lock magnets 44, 46, 48, 50 acting attraction.

In the absence of a magnetic key or corresponding external magnetic forces, the magnetic attraction forces of the lock magnets 44, 46, 48, 50 cooperate so that the Magnetmitnehmer 36, 38 pull each other by itself in the locked position.

In addition, it is also possible to provide a spring mechanism, not shown here, such as a compression coil spring, a tension spring, leaf spring, elastomer block or even a rubber ring, for example as described in EP 1 355 550, which moves the magnetic carrier into the locking position or holds it in the locking position. The key magnets must then be dimensioned so that they can overcome the attraction of the lock magnets and the reaction force of the spring mechanism. reference numeral
