Definitions
- the present invention concerns the subject of necklaces and more generally of hollow beads threaded on a string to form a decorative object, like wrist bracelets, ankle bracelets or the like, all these objects being thereafter called necklaces.
- Necklaces particularly pearl necklaces, are typically worn by women after they have been sold by a retailer.
- the manufacturer of the necklace commonly delivers a semi-finished product to the retailer; this semi-finished product consists of a simple string, called hereafter a temporary string, on which beads, particularly pearls, are threaded. It is generally delivered without a clasp closing the temporary string; escapement of beads is prevented by at least one knot made at each end of the temporary string.
- the retailer uses a different, definitive string to thread the beads definitively, upon assembly of the finished product ready for final delivery to the end user.
- the total clearance i.e. the difference between the length of the definitive string and the total width of the beads, should be uniformly distributed along the string;
- each knot serves as a spacer to prevent friction between the beads
- the part of the string containing the device is made in a material allowing the insertion of a microprocessor or chip.
- This chip is able to exchange data with a separate control apparatus; the control apparatus can, in a known manner, either erase and replace the data stored in the chip, or only read some of them, this depending on its authorization level.
- the data can reflect for instance a serial number, a trade mark, a manufacturer's and/or retailer's name, a date of manufacturing.
- the device is merely an inscription, legible with or without instruments like a magnifier, written on a part of the string.
- confidential data can be coded.
- the string is made of a multiple- stranded cable, preferably a steel cable.
- a coating e.g., a highly adhesive plastic coating, known in itself, is applied on the steel cable to avoid any abrasion effect of the strands on the holes of the beads.
- the part of the string carrying the inscription can, in particular, be a nipple at one end of the string.
- the string being made of a mechanically resistant, multiple-stranded cable, cannot be cut by usual scissors. It is absolutely maintenance-free, in contrast to the prior art, where maintenance was necessary because of the risks of breakage.
- the string according to this embodiment identifies the necklace by an inscription, on a nipple attached to the string.
- Said nipple can be at the immediate vicinity of a pendant; said pendant can also, in a know manner, function as the clasp of the necklace.
- the string is terminated, at least at one of its two ends, by a knob affixed to said end.
- This knob can cooperate, in a manner known in itself, with a clasp mechanism of the so-called bayonet type.
- the knob is protruding in the same direction as the terminal part of the string, and can engage in a hole of the clasp only at a limited number of angular positions. After its engagement, the knob is rotated inside the clasp, this rotation entailing a locking effect.
- the cable string is mechanically resistant to a relative angular rotation between its two ends.
- the knob, or the nipple, or both are arranged so as to move freely in rotation with regard to the string. This is particularly useful in the case of a bayonet-type clasp, because it allows to avoid any constraints that could remain in the string after the necklace is attached.
- the nipple carrying the inscription has the general shape of a cylindrical bead with a bayonet-type protrusion, allowing to attach the necklace.
- This bead, without the protrusion is first threaded on the string, which has an end that cooperates with a striction in the hole of the bead, allowing free rotation.
- a closing cork, carrying the bayonet- type protrusion is then brought on the cylindrical bead, preferably in a nonremovable manner such as stamping, soldering, or screwing with a high couple.
- the above described embodiments allow the manufacturer of the necklace to deliver a necklace with a standard clasp, accommodating bayonet-type protrusion parts to be inserted on both sides in a known manner. As the clasp is more and more becoming a decorative part of the necklace, being used as a pendant, the retailer can then propose to the end user a choice of decorative clasps that fit the necklace style, thus simply removing the standard clasp delivered by the manufacturer with the necklace.
- Dampers are preferably inserted between two consecutive beads by the manufacturer to serve as spacers between said two consecutive beads. These dampers are preferably compressible in order to remove any tension. They can also have a decorative function.
- the knob is fixed, in an unremovable manner, to the end of the string that is opposed to the nipple's end. Such fixing can be made by a mechanical seal, i.e. by permanently deforming some parts of the knob to make them bite on the string.
- the outer portion of the knob is a bayonet-type protrusion, allowing to close the necklace by cooperating with the standard clasp, as described above.
- one end of the string e.g. the nipple
- the other end e.g. the knob
- one free-rotation mechanism is sufficient to avoid any constraints in the closed necklace.
- Figure 1 is a longitudinal cross-section of one end of the finished necklace according to a first embodiment of the invention
- Figure 2 is a longitudinal cross-section of a subset of figure 1 ;
- Figure 3 is a view of the opposite end of the string of same necklace
- Figure 4 is a longitudinal cross-section of figure 3;
- Figure 5 is a perspective view of a necklace according to a second embodiment of the invention.
- the string 1, a multiple-stranded cable, is terminated by a steel head 11 that is unremovably fixed to its end.
- a nipple 3 Prior to the threading of any beads 9 on the string 1, a nipple 3 is brought to the end of string, according to the following sequence : a) a hollow cylindrical bead 7 is adapted to receive the head 11 in its hollow part, in free rotation. The bead 7 is threaded on string 1 from its opposite end, and the head 11 is inserted into its hollow part;
- a bayonet-type cork 10 is secured, by means known in themselves, by partial insertion into its hollow part, thereby preventing head 11 from escaping from the bead 7.
- the securing means can include stamping, soldering or screwing. It allows free rotation of head 11 inside the hollow part;
- the nipple 3 is formed by bead 7 and cork 10, secured together and imprisoning the head 1 1 of string 1.
- Figure 1 shows a chip 4 inside the bead 7. It can be placed immediately under the external surface of bead 7, so as to be protected from any shock, and still allow interaction with a mobile control apparatus 5 that can be brought close to said surface of bead 7. This allows the exchange of data between the control apparatus 5 and the chip 4 and can include the providing of energy to chip 4 by control apparatus 5.
- the portion of the bead 7 situated between chip 4 and the external surface of bead 7 can advantageously be transparent, in order to facilitate the transmission of optical data.
- FIG. 2 shows in more detail the bayonet-type cork 10, with a hollow part 13 cooperating with the hollow part of the bead 7 to imprison the head 11 of string 1.
- the external cylindrical surface 8 of the cork 10 is secured, e.g. by stamping or soldering, to the internal corresponding surface of said hollow part.
- FIG. 3 and 4 show the other end of string 1.
- a knob 6 terminates a shaft 12 secured to the last millimeters of string 1. No rotation is possible between string 1, shaft 12 and knob 6.
- Knob 6 is adapted to bayonet-type clasps. Such a clasp can receive, on one side the knob 6, and on the other side the bayonet part of the cork 10, thereby closing the necklace in a known manner.
- the rotations entailed by actuating the bayonet mechanisms are taken over by the fitting between the head 1 1 and the nipple 3, which are free in relative rotation.
- Figure 4 shows a longitudinal cross-section of string 1, shaft 12 and knob 6 as represented in Figure 3.
- the beads are, as the next step, threaded on string 1 from the free end 13 opposite to the head 11 , before said end 13 of string 1 is inserted into shaft 12.
- the beads threaded allow for a sufficient space to seal shaft 12 on the last portion 14 of string 1. Such sealing is done after all the beads are threaded on string 1.
- Shaft 12 can e.g. be stamped on part 14 of the string 1.
- Figure 5 shows another embodiment of the invention, in which the nipple 3 identifies the necklace 2 by an inscription 4.
