Abstract

An monitor support device incorporating a desk attachment and monitor mounting means enabling a monitor to be mounted at least partially beneath an aperture in a desktop so as to be viewable through said aperture.

Description

FIELD OF THE INVENTION

The present invention relates to supporting monitors, including VDUs, television and video monitors and notebook and laptop computers. In particular, the present invention is related to a universal standards based adjustable ergonomic monitor support/security device designed to house at least part of a monitor beneath the surface of a desk or worktop and present it at the optimum viewing angle and distance to the user.

BACKGROUND TO THE INVENTION

Computer displays and monitors have traditionally been mounted on the surface of a desk or work station, and are typically positioned either at eye level or within 10 to 20 degrees below horizontal eye level. The accompanying mouse and keyboard are traditionally also located and used on the desk surface. However, it has been found that these arrangements are ergonomically sub-optimal. Neck, shoulder and eye strain can occur with use of such arrangements over an extended period. The most naturally comfortable position to review material, such as reading material or information displayed on a VDU is looking down at an angle of between 10 degrees and 40 degrees from the horizontal from a distance of between 600 and 900 mm (ISO11064 Part 4:2004). The eyes naturally accommodate this with minimal head movement. The current practice of mounting monitors on desks can cause undue stress and strain on the neck, shoulders and eyes. Touch typists in particular regularly switch their line of sight between a keyboard, working papers and the screen. It is desirable to have all three of these views to fall within a single plane or line of sight.
Initial attempts to overcome these problems ameliorated some of the drawbacks, but still required the user to look up at the screen. For example, lowering the desk height to accommodate the keyboard and mouse resulted in the desktop being too low for comfortable use, writing, reading, etc.
For example, DE4240349 discloses an ergonomically efficient keyboard for use with computer terminals, wherein the keyboard is set beneath the level of the surface of a work desk on which the computer monitor is located. A problem with this arrangement is that the keyboard is not at the correct height for optimal typing and the viewing angle of the VDU is not addressed.
There are a number of solutions to the problem that rely on embedding the monitor or display within the desk.
U.S. Pat. No. 5,120,117 relates to a preformed platform for assembly into a cut-out section of a work table or counter to support a computer keyboard and monitor according to accepted ergonomic principles. The base of the keyboard is supported at a level below the ordinary desk height so as to allow typing to be done with the wrists substantially level and straight. A wrist support bar is provided to support the wrists and reduce wrist strain. The monitor and the keyboard are positioned with their operative centres at similar heights from the floor and at similar distances from the operator for optimum operator comfort and efficiency. This system is limited for use and security with CRT monitors. Furthermore, an additional problem with this system is that if the monitor is moved and/or changed, the critical angle may not be reset, as the system does not offer a full range of adjustments. The working desk height is also difficult to achieve, and the system cannot be retrofitted to a desk.
DE4225662 discloses a work desk with a frame that supports a main desk panel and at the rear is an upstand that has a glass front panel. Within the main body of the upstand is a computer monitor that is supported on a carriage. The carriage is mounted on a vertical column that allows the height and angle of inclination to be adjusted. The carriage may also be positioned horizontally by moving along a guide that consists of two profiled section rails. This system is limited to use with CRT monitors and requires a large and cumbersome purpose built desk. Furthermore, the monitor screen remains positioned substantially on top of the working surface of the desk, and could easily be used at the wrong angle.
FR2774571 discloses an arrangement where the computer monitor is held under the work surface by a support made of fabric. The sides of this are fixed to tubular frames that are articulated on two bars that are fixed under the work surface. One frame is held in slots in the back of the bars and the other frame is held in hooks in the front of the bars. A problem with this arrangement is that the fabric does not allow for air circulation, and as a result, overheating of the computer monitor may occur. Furthermore, the fabric is not designed to securely hold the monitor at any particular or correct angle. Again, this arrangement is limited to use with CRT monitors. It is well known that a health and safety aspect is involved with the lifting of CRT monitor which are heavy in weight. Retrofitting is not possible with this system either.
CH686022 discloses a desk with a number of different support surfaces for receiving the various components of a personal computer, e.g. the keyboard, the monitor and the processor. The monitor is supported by a surface which is angled rearwards and downwards, behind the front support surface for the computer keyboard, so that the monitor screen is visible to the keyboard operator without further movement of the head. However, the arrangement requires that the desk surface be interrupted to accommodate the top of the monitor. The resultant loss of available work space on the desk surface is undesirable. Furthermore, the system is not adaptable for use with varying monitor sizes or types. Further problems include its unsuitability for retrofitting and poor security.
U.S. Pat. No. 4,207,405 and U.S. Pat. No. 6,796,536, as well as US registered designs Des 430,165, Des430,570, and U.S. design application Ser. No. 29/205,730 all relate to free-standing supports suitable for supporting a monitor at an angle.

DETAILED DESCRIPTION OF THE DRAWINGS

The present invention provides an adjustable ergonomic monitor support device adapted to house a monitor securely and at the correct angle beneath the surface of a desk. FIG. 1 shows a desk incorporating a monitor support device according to the invention. As shown, the monitor support device allows a monitor, in this case a flat panel monitor, to be supported beneath the working surface of a desk, the screen of the monitor being visible through an aperture provided in the desk's upper surface. The monitor support device enables the monitor to be presented at the optimum viewing angle and distance for the user.
As shown in FIGS. 2 and 3, the monitor support device has a desk attachment 10 shown affixed to the underside of the desk, a monitor bracket shown affixed to the back of a monitor, and a third component, a spacer arm member linking the desk attachment and the monitor bracket. The resultant monitor support device combination permits the monitor to be in effect suspended and locked beneath the desktop.
FIG. 4 shows the assembled support arrangment from FIG. 2 in greater detail. Desk attachment 10 is securable to the underside of a desktop by way of screw holes 13. Spacer arm member 20 comprises a desk mounting plate 21 connected to an inclined slotted plate 22. The desk mounting plate 21 is slidably receivable within desk attachment 10 by way of corresponding flanges 15 on the underside of desk attachment 10. Finally, monitor bracket 30 is a flat panel monitor bracket having a spacer arm-engaging plate 31 connected to a monitor mount 33 via an intermediate portion 32.
Mating bolts (not shown) are used to releasably but securely couple the spacer arm-engaging plate 31 to inclined slotted plate 22 by threading the mating bolts through screw holes 34 and two of the slots provided in the inclined slotted plate 22. In the arrangement shown in FIG. 3, the two inner slots 19 are used, resulting in the monitor bracket 30 being centrally orientated relative to the inclined slotted plate 22. As mentioned below, the multiple slots in the inclined slotted plate 22 may be used in alternative combinations to alter the position of the monitor bracket 30 relative to the inclined slotted plate 22.
It will be noted that the position of the monitor bracket 30 in FIG. 4 differs slightly from its position in FIG. 2. This is to show that the monitor bracket may be rotated through 180 degrees and re-secured to part 22 using the same screw-hole 34 and slots 29 combination. This arrangement allows the monitor mount portion 33 to sit higher than the spacer arm-engaging plate 31. The provision of the slots 19 allows the whole monitor bracket to slide the length of the elongate support plate 20 to reach a desired position for a monitor secured thereto. As shown in FIG. 5, by orientating the monitor bracket with the monitor mount 33 up most, the highest possible position for a monitor is achieved, in which the monitor would protrude through the hole in the desk. This is shown clearly in FIGS. 6 and 7.
FIGS. 8 and 9 show a desk attachment 10 according to one embodiment of the invention. The desk attachment 10 comprise a substantially planar base plate 11 formed by a substantially quadrilateral plate. A pair of corners 12 extend from opposite sides of the side of the base plate 11, forming a substantially H-shape. The corners 12 are each provided with a screw hole 13. The screw holes 13 are used to affix the desk attachment 10 to the underside, or as discussed later the inner wall, of a desk. The base plate 11 is also provided with a substantially straight ventral slot 14. As best seen in FIG. 9, a pair of curved flanges 15 are set on opposing sides of the base plate 11 and disposed substantially parallel to each other. The curved flanges 15 provide between them a support groove 16 to receive plate 21 of spacer arm member 20, described below.
Spacer arm member 20 is shown in full in FIG. 10 to comprise a desk mounting plate 21 connected to a inclined slotted plate 22. The desk mounting plate is substantially quadrilateral and comprises two side edges 23 substantially parallel to each other and an end edge 24 substantially parallel to a connecting edge 25, which in turn connects the desk mounting plate 21 to the inclined slotted plate 22 via an angled portion 27. The desk mounting plate 21 contains a threaded bolt hole 26 centrally located with respect to the side edges 23 and located close to the end edge 24. The desk mounting plate 21 is substantially equal in width to the distance between the two flanges 15, so as to enable the desk mounting plate 21 to slide between the flanges. In use, the spacer arm member 20 can be affixed to the desk attachment 10 by means of a screw or bolt (not shown) through the bolt hole 23 and through the ventral slot 14. The ventral slot 14 allows the position of the spacer arm member 20 to be adjusted relative to the desk attachment 10 when installing. Once installed, the position of the monitor is fixed. The bolt may then be further secured to the desk (especially if the desk is wooden). This provides security in the event of an attempt to remove the monitor from the desk.
The desk mounting plate 21 is connected to the inclined slotted plate 22 by an angled portion 27. The angle between the desk mounting plate and slotted plate is desirably approximately 135 degrees. The angle is fixed to ensure that the most desirable viewing angle (of between 10 and 40 degrees from the horizontal) of the user to the screen of the monitor is achieved.
The inclined slotted plate 22 comprises is an elongate rectangular shaped plate with five substantially parallel slots running along most of its length. The slots comprise an outer pair 28, each located proximal to the edge of the inclined slotted plate 22, an inner pair 29, each located proximal to the centre of the inclined slotted plate 22, and a central slot 40. The outer pair 28 are spaced apart in a parallel relationship approximately 100 mm apart. The inner pair 29 are in spaced apart parallel relationship approximately 70 mm apart. The dimensions are chosen to be mate-able with the Video Electronics Standards Association (VESA) standards, such as the Flat Display Mounting Interface (FDMI). This is a VESA standard for mounting flat panel monitors, and other displays. The FDMI standard is also referred to as VESA mount.
As shown in detail in FIGS. 12 and 13, monitor bracket 30 comprises a spacer arm-engaging plate 31 connected to a monitor mount 33 via an intermediate portion 32. The spacer arm-engaging plate 31 comprises a substantially planar quadrilateral plate with a series of screw holes 34. The spacer arm-engaging plate 31 comprises a substantially rectangular plate; the intermediate portion 32 being connected at one of the short sides of the rectangle. The intermediate portion 32 has a substantially S-shaped cross-section to enable the maintain spacer arm-engaging plate 31 substantially parallel to, but spaced apart and offset from, the plane of the monitor mount 33. The monitor mount 33 extends from the intermediate portion 32 in a direction away from the spacer arm-engaging plate 31. The monitor bracket may therefore be said to comprise a dogleg profile.
Mating bolts (not shown) are used to affix the spacer arm-engaging plate 31 to the inclined slotted plate 22 by threading the mating bolts through the screw holes 34 and slots 28, 29, 40. The monitor mount 33 is of substantially cruciform shape. Each cruciform arm 35 is provided with a first monitor attachment point 38 and a second monitor attachment point 39 in the form of screw holes. The first and second monitor attachment points 38, 39 are separated from each other by a frangible portion 37 of the cruciform arm 35. A weakened neck 37 a is formed by way of indentations on each edge of the arms 35, together with an elongate slot 37 b between each indentation. These features enable the frangible portion 37 to be easily snapped off the rest of its arm, preferably by hand.
In one embodiment of the invention the full sized X-shaped monitor mount may be dimension for use with a VESA 100 monitor. The frangible portion 37 permits the user to snap off the second monitor attachment portions 36 to suit a monitor having a lower VESA specification, such as VESA 70 or VESA 75.
It will be appreciated that the length of intermediate portion 32 is chosen to keep the planes of parts 31 and 33 sufficiently far away from one another so as to allow the monitor support fit different sizes and shapes of flat panel monitor. One skilled in the art will be aware that the backs of many flat panel monitors are provided with a shallow square or rectangular recess into which a mounting support may be received. Portion 33 is designed to be received into any such recess if required, wherein intermediate portion 32 extends out of the recess to keep part 31 clear of the monitor housing.
As mentioned above, holes 34 in the flat plate section 31 are used to secure component 30 to the inclined slotted plate 22. This fitting allows the monitor to be moved up and down the support plate to accommodate different sizes of flat panel monitors (FPM) and to be inverted to allow the FPM to appear above the worktop/desk level as shown in FIGS. 4 to 7.
With reference to FIGS. 14 and 15, it is shown that the provision of a central slot 40 in angled support 22 also allows flat plate 31 to be rotated through 90 degrees and secured to the spacer arm member to allow a monitor to be positioned either side of the spacer arm member's central longitunal axis. In such arrangements, intermediate portion 32 would be adjacent one side of the monitor rather than adjacent its base (as in FIG. 6) or adjacent its top (as in FIG. 2).
In addition to its use with flat-panel monitors, the monitor support device of the invention is also suitable for use with laptop computers. FIG. 16 shows a laptop version of the assembly. In this assembly, monitor bracket 30 has been replaced by a laptop support 50. Laptop support 50 follows the shape of an open laptop, with two substantially rectangular faces linked along one of their longer edges. The angle between the two faces is shown to be just greater than a right angle, although alternative angles could be provided. In this embodiment, laptop support 50 would have started out as a single substantially rectangular sheet of metal or hard plastic and been folded about its central axis, although in alternative embodiments the laptop support may comprise any number of parts joined together to provide the required shape.
As seen in FIGS. 18 and 19, laptop support 50 comprises a laptop receiving base plate 51 and a back plate 52. Back plate 52 is provided with holes 57 identical in shape and relative position to the holes 34 provided in monitor mount 33. Accordingly, holes 57 enable backplate 52 and hence laptop support 50 to be mounted on the inclined slotted plate 22 of spacer arm member portion 20. Again it will be appreciated than either slot pair 18 may be utilised to centre the laptop support, or alternatively central slot 40 may be used in combination with one of slots 18 to position the laptop support either side of inclined slotted plate 22.
As best seen from FIG. 17, the laptop receiving base plate 51 is provided with a series of ventilation holes/slits 56 to provide ventilation and air circulation for a laptop positioned thereon. It is well known in the art that as with any electrical equipment, laptops generate a substantial amount of heat when powered on and a laptop's own ventilation holes are often located on around its base. The ventilation slits 56 ensure that a laptop located thereon does not overheat as a result of insufficient ventilation. The ventilation holes or slits may take an alternative form in other embodiments. The base plate 51 is also provided with turned-up or rolled edges 53 to securely hold a lap top base within the laptop support to prevent it falling off. The rolled edges are angled so as to accommodate any size of laptop.
Referring again to FIG. 16, apertures 54 for wires are formed in the back plate 52 adjacent the backplate/base plate interface. The apertures 54 allow a laptop to remain plugged into the mains and/or to any other equipment while it is supported in the laptop support.
The side edges 58 of the backplate 52 have been rolled back to impart strength to the backplate. Strap holes 59 are provided towards the base of each side edge 58 to accommodate a security strap or straps (not shown) for securing a laptop to the laptop support. Security straps may also be provided for the flat panel monitor support.
In FIGS. 2 and 6, the desk attachment is shown affixed to the underside of the desk. In alternative arrangements, desk attachment 10 may be fitted to a substantially vertical surface at the back of the desk. This would be desirable for a desk wherein less than the required 600mm of desktop is available behind the desk's aperture for attaching the desk attachment to the underside of the desktop.
FIG. 20 shows how the monitor support device is adaptable for a desk connection of this sort. Monitor bracket 30 is secured to what would have been previously considered the “underside” of spacer arm member piece 20, with the previously-considered “upper” face of the desk mounting plate 21 cooperating with the previously-considered “underside” of base plate 10. With base plate 21 secured to a vertical surface under and to the rear of the desk, a flat panel monitor may be mounted onto the monitor mount 33 at the correct height for a correct viewing angle.
When the monitor is full submerged beneath the desk, as seen in FIG. 1, a toughened glass panel may be used to fill the aperture enabling the total desktop to be used as a desk. A half panel can be inserted where the monitor is semi submerged as in FIG. 7. It may be desirable to have the monitor screen semi submerged where touch-screen technology is being utilised.
If the screen is not being used, the entire aperture may be filled by one or multiple wood panels to provide a full desktop surface.
FIG. 21 shows an alternative embodiment of spacer arm to that shown in FIGS. 10 and 11. Spacer arm member 220 is shown in FIG. 21 to also comprise a desk mounting plate 221 connected to a inclined slotted plate 222. The desk mounting plate 221 and inclined slotted plate 222 have the same form as desk mounting plate 21 and inclined slotted plate 22. In the embodiment shown in FIG. 21, the angle of connection of plate 221 to plate 222 is different however.
The desk mounting plate 221 is still connected to the inclined slotted plate 222 by an angled portion 227, but the angle between the desk mounting plate and slotted plate is desirably approximately 45 degrees. This embodiment allows the spacer arm to be used in conjunction with a desk attachment mounted to the underside of a short section of desk (such as region 250 in FIG. 2). When used with spacer arm 220, the desk attachment would be reversed so as to enable the desk mounting plate 221 to slide into the desk attachment in a direction from the front/rear edge of the desk towards the desk aperture, resulting in the angled portion 227 resting at the front/rear edge of the desk.
