A desk accessory support for use with a desktop has an upper surface, a lower surface and an edge extending between the upper and lower surfaces. The support includes a first abutment for abutting the upper surface, and a second abutment for abutting the lower surface. A connecting structure is configured for connecting the first and second abutments to each other. The first and second abutments and the connecting structure define a substantially U-shaped recess for receiving the edge of the desktop.
Description




TECHNICAL FIELD




The present invention relates to means for supporting a keyboard, a VDU monitor or the like in relation to a desk having an upper surface and an opposed lower surface.




The invention has been developed primarily for use with an office desk or work station and will be described hereinafter with reference to that application. However, it will be appreciated that the invention is not limited to that particular field of use and is also applicable to other work surfaces, storage surfaces or the like.




BACKGROUND ART




Hitherto, the inclusion of a keyboard platform on an office desk has necessitated specific mechanical alterations of that desk (for example a cut out section) to accommodate the linkage mechanism joining the platform to the desk. This is particularly so for linkage mechanisms which allow height adjustment of the keyboard platform. Because of the many configurations and variations required to meet the specific demands of the office and consumer markets it is difficult for manufacturers to conveniently and cost effectively produce the desks and associated keyboard supporting platforms.




The keyboard to be placed on the keyboard platform is generally associated with a computer having a screen which is located on the desk surface. However, the narrow width of most modern desks makes it increasingly difficult, even with the use of known keyboard platforms, to maintain a distance between the screen and the eyes of the operator using a keyboard which meets the internationally recognised optimum of 550 mm. Moreover, once an optimum is achieved, further height or angular adjustment of the screen is generally impracticable, whether it be to share screen information or for operator convenience of comfort. Attempts to provide adjustable monitor supports also suffer from the disadvantage of requiring desk surface modifications. To avoid this it has been proposed to employ a monitor platform attached to the desk via an arm extending from a screw clamp. Such arrangements are often insecure because of the weight of the monitor. Screw clamps cannot be placed at the front edge of the desk because their bulk interferes with the attachment and/or use of a keyboard and renders the desk surface unusable. Attachment of screw clamps at the desk rear or desk side edges tends to damage the desk and to interfere with placement of desks against a wall or screen (if clamped at the rear) or side-by-side (if clamped at the side). In general, monitor supports tend to occupy an excessive desk area or interfere with desk space.




It is an object of the present invention, at least in the preferred embodiment, to overcome or substantially ameliorate one or more of the disadvantages of the prior art.




DISCLOSURE OF THE INVENTION




According to one aspect of the invention there is provided a desk accessory support adapted to co-operate with a desktop having an upper surface and a lower surface, the support including:




a first abutment means adapted to abut the upper surface;




a second abutment means adapted to abut the lower surface;

MODES FOR CARRYING OUT THE INVENTION




Referring to FIG.


1


and

FIG. 2

, there is shown a keyboard support


1


for a desk


2


having a substantially planar upper surface


3


and an opposed co-extending lower surface


4


having respective straight edges


5


and


6


. The edges are joined by a vertical sidewall


7


which extends in a plane and that is substantially normal to the upper and lower surfaces. Support


1


includes a first mounting means in the form of a planar rectangular metal plate


11


which abuts the adjacent upper surface


3


. A second mounting means in the form of a second planar metal rectangular plate


12


is connected to plate


11


by way of an intermediate portion


13


and abuts the adjacent lower surface


4


. Plates


11


and


12


are substantially parallel and, in combination, maintain support


1


in a predetermined disposition with respect to desk


2


. A linkage assembly in the form of a pantographic linkage mechanism


21


extends from a first pair of parallel brackets


22


adjacent plate


12


to a second pair of like brackets


23


. A keyboard support platform in the form of a support surface


30


is mounted to brackets


23


to selectively support a keyboard (not shown).




With reference to

FIGS. 1 and 2

, plates


11


and


12


and connecting portion


13


are preferably integrally formed from a single folded steel plate such that the distance between the opposed plate faces


11


,


12


is substantially equal to the distance between desk edges


5


and


6


. In other embodiments, opposed faces


11


,


12


are disposed slightly further apart and use is made of respective strips of dense resilient foam to facilitate an interference fit between support


1


and desk


2


, while also reducing the risk of any point loading.




In other embodiments plates


11


and


12


and connecting portion


13


are integrally constructed from plastics.




Linkage mechanism


21


includes four parallel arms


35


which are arranged in two spaced apart pairs which extend between respective brackets


22


and


23


to allow altitude adjustment of platform


30


with respect to desk


2


. As would be appreciated by those skilled in the art other linkage mechanisms are also suitable. For example, in some embodiments the linkage mechanism allows tilt and/or altitude adjustment of platform


30


, while in other embodiments platform


30


is fixed with respect to desk


2


.




Linkage arms are connected to brackets


32


at a distance inwardly of connection


13


at the desk edge. Consequently the weight of platform


30


results in a torque being generated which is transmitted by arm


35


to plates


11


and


12


. This torque forces the plates into more secure engagement with the respective adjacent surfaces


3


and


4


. If an object such as a keyboard is placed on platform


30


it will increase the torque and hence the plates will more securely impinge upon the adjacent desk surfaces. Accordingly, an inherently safe self locking system is provided. For example, if an operator or other person inadvertently applies a load to platform


30


, by leaning on it or otherwise, support


1


is further locked to desk


2


.




As best shown in

FIG. 1

, upper and lower surfaces


3


and


4


are L-shaped and define a corner work station for a computer operator.




In the

FIGS. 1 and 2

embodiment, plate


11


includes longitudinally extending edges


31


and


32


which are joined by transverse by extending edges


33


and


34


. Plate


12


also includes longitudinally extending edges


31


and


32


and transversely extending edges


37


and


38


. As shown, edge


38


is disposed intermediate edges


33


and


34


although in other embodiments edge


38


is adjacent to edge


34


.




Plate


11


includes a slot


40


which extends longitudinally inwardly from edge


34


and terminates at rounded end


41


. Slot


40


allows a cord extending between the keyboard and the associated computer to be discretely passed under plate


12


and then onto surface


3


. This results in a more aesthetically pleasing arrangement which is also less likely to hinder the height adjustment of platform


30


. In some embodiments slot


40


is large whereby plate


11


is in the form of a frame extending inwardly from the periphery of the plate shown in FIG.


1


.




Support


1


is shown in

FIG. 1

mounted to the corner of the L-shaped surfaces of desk


2


. This is effected by initially manoeuvring edges


34


and


38


to be adjacent edges


7


and


8


respectively. Thereafter, plates


11


and


12


are biased away from each other to separate ends


34


and


38


sufficiently to allow their progression beyond edges


5


and


6


. The biased is then removed allowing plates


11


and


12


to co-operatively grip surfaces


3


and


4


, and, if required, support


1


further manoeuvred into a desired configuration. Although platform


30


is shown bridging the corner of desk


2


, it is equally suitable for mounting along one of the straight edges, that is, with edge


34


maintained substantially parallel to any edge of the desk.




In

FIG. 1

, platform


30


extends transversely beyond plates


11


and


12


and includes bevelled sides


45


which lie flush with the adjacent sidewall


7


. For embodiments of support


1


which are intended for symmetrical mounting in the corner of desk


2


, bevelled sides


45


extend at 45° to edge


34


. In other embodiments platform


30


transversely coextends with plate


11


and includes straight sides.




Reference is now made to

FIG. 3

, where corresponding features are denoted by corresponding reference numerals. More particularly, a support


46


is illustrated which includes a plate


12


(second abutment means) having a down turned edge


38


defining a lip


47


for facilitating initial placement of the support on desk


2


. Moreover, support


46


includes two parallel spaced apart longitudinally extending tracks


49


disposed between plate


12


and respective brackets


22


. The brackets are captively and slidably mounted to the tracks to allow longitudinal progression of platform


30


between an extended and retracted configuration with respect to desk


2


. Platform


30


is illustrated in the extended and retracted configurations by unbroken and broken lines respectively. Progression of platform


30


toward the extended and retracted configurations is limited, for example, by bump stops (not shown) adjacent portion


13


and lip


47


respectively. In some embodiments at least one of tracks


49


include a plurality of spaced apart locking formations which are selectively engaged by a complementary formation on the adjacent bracket


22


to effect positive locating of that bracket with respect to the track.




Platform


30


, in some embodiments, has a sufficiently large surface area to accommodate, in addition to the keyboard, one or more other input devices such as a mouse, joystick, removable hard drive, tape drive or the like. However, in some circumstances an operator requires additional space to conveniently locate input devices for the computer other than directly on platform


30


. This is easily achieved through use of the embodiment of the invention illustrated in FIG.


4


and generally designated as auxiliary platform


52


.




Auxiliary platform


52


includes plates


11


and


12


and portion


13


, similarly to the other embodiments described above. However, in this case, auxiliary platform


52


, is substantially smaller than platform


30


and fixed with respect to plates


11


and


12


by a pair of parallel underlying beams


53


. These beams are fixedly attached to plate


12


and convert any torque arising from a load applied to platform


52


into a locking force between plates


11


and


12


and respective adjacent surfaces of desk


2


.




In some embodiments platform


52


is mounted to platform


30


rather than desk


2


.




Platform


52


is intended to support a mouse


54


or other input device. In this embodiment the upper surface of the platform includes a neoprene layer


55


to facilitate operation of mouse


54


.




Platforms


30


and


52


can all be retrofitted to existing desks or other surfaces without any modifications being required. Moreover, platforms


30


and


52


are easily moved for optimum placement by applying a bias to the support surface to counteract the gravitational bias applied by any load carried by that surface.




Platforms


30


and


52


being cantilevered from plate


12


are self-locking and ensures that when a load is applied to the platform surface that the support will be more securely located on the desk.




As support


1


extends beyond sidewall


7


of desk


2


it provides a user with additional desk space and allows that user to comfortably and easily maintain a greater distance between their eyes and the screen.




Reference is now made to

FIGS. 5 and 6

which illustrate an alternative support


60


, where corresponding features are denoted by corresponding reference numerals. These figures are intended to show the direction the forces acting upon plates


11


and


12


during upward and downward adjustment of platform


30


. More particularly, in

FIG. 5

platform


30


is in the raised configuration and a downward force represented by arrow


61


is applied to move the platform to a reduced height with respect to desk


3


. This results in the generation of forces represented by arrows


62


and


63


respectively on the front and rear edges of plates


11


and


12


. These forces act to further lock support


60


to desk


3


. When platform


30


is in the lowered configuration, as shown in

FIG. 6

, it is necessary to apply an upward force, represented by arrow


65


to more the platform surface to a higher position with respect to desk


3


. With the application of force


65


, two forces are generated, represented by arrows


66


and


67


, respectively, which act on the front and rear of plates


12


and


11


. Again, locking action is effected.




The application of either of forces


61


or


65


has the desired effect of locking support


60


to desk


3


, notwithstanding the opposed nature of these forces.




Reference is now made to

FIG. 7

which is a perspective view of two plates


75


and


76


which form part of a keyboard support according to the invention. For the purposes of clarity the linkage assembly has been omitted, although it will be appreciated that, in use, such an assembly extends from the bottom of plate


76


.




Plates


75


and


76


are opposed and include respective flanges


77


and


78


which extend toward the other of the plates. Preferably, each flange extends normally from its respective plate.




Flange


77


includes two spaced apart circular apertures


79


and corresponding nuts


80


. In other embodiments nuts


80


are omitted and apertures


79


are threaded.




Flange


78


includes two spaced apart parallel extending slots


81


which, in use overlie apertures


79


. Respective bolts


82


are inserted through slots


81


and apertures


79


, and threaded into engagement with nuts


80


to maintain flanges


77


and


78


in a fixed spaced apart configuration.




During installation of the keyboard support to a desk, bolts


82


are loosened to allow movement of plates


75


and


76


into engagement with respective opposed surfaces of a desk. Thereafter, bolts


82


are tightened with respect to nuts


80


to securely maintain the plates in the engaged configuration. Accordingly, plates


75


and


76


accommodate a variety of desk thicknesses.




Plate


75


includes a mouse pad


83


in the top right hand corner. This allows a user convenient access to the keyboard, which is located on the support platform (not shown) and a mouse located on pad


83


.




An alternative arrangement is illustrated in

FIG. 8

where, again, the linkage assembly has been omitted for clarity purposes. More particularly, two spaced apart, substantially parallel plates


85


and


86


are integrally formed and are joined by an intermediate curved resilient portion


87


. Portion


87


flexes to allow a greater separation between plates


85


and


86


, thereby accommodating a range of desk thicknesses, while resiliently biasing plates


85


and


86


to co-operatively grip the desktop (not shown).




An alternative embodiment keyboard support


90


is illustrated in FIG.


9


. Support


90


is similar to support


60


, as illustrated in

FIG. 6

, and corresponding features are denoted by corresponding reference numerals. The plates


11


and


12


of the

FIG. 9

embodiment are spaced slightly further apart than those shown on

FIG. 6

to provide a small gap between the plates and the respective adjacent surfaces of desk


3


.




Plate


11


and plate


12


both include spaced apart rubber feet


91


and


92


which are respectively disposed at the front and rear of those plates. When a downward load is applied to platform


30


feet


91


and


92


are biased into gripping engagement with the adjacent desk surfaces.




Plate


11


also includes a rearwardly disposed spherical roller


93


which is engaged with the top surface of desk


3


when an upwardly directed force is exerted upon platform


30


. Such an upwardly directed force will also remove feet


91


and


92


from gripping engagement with the desk surfaces. Accordingly, movement of support


90


is facilitated.




The

FIG. 9

embodiment of the invention is intended for mounting to the straight edge of a desk and for subsequent transverse movement along that edge. Preferably, therefore, desk


3


includes a guide in the form of a transversely extending track


94


which overlaps with the rear of plate


12


to facilitate a smooth progression. Track


94


is maintained against desk


3


by way of a plurality of spaced apart screws


95


.




Support


90


is easily transversely progressed by a user who simply needs apply an upwardly directed force to platform


30


to overcome the gripping engagement of feet


91


and


92


. Support


90


is then progressed transversely, as required, and the upwardly directed force is removed. Platform


90


is then biased downwardly under the influence of gravity and from any resilience between plates


11


and


12


whereby feet


91


and


92


are again biased into gripping engagement with desk


3


.




In another embodiment plate


12


includes formations for selectively engaging with a plurality of corresponding transversely spaced apart formations on the lower surface of desk


3


. The interengagement between the formations effecting an even more positive engagement between the desk and support. When an upwardly directed force is applied to the platform the rear edge of plate


12


is progressed downwardly such that the formations are disengaged and either transverse and/or longitudinal movement of the support relative to the desk can occur.




With reference to

FIG. 10

there is shown an embodiment similar to that of

FIG. 1

but wherein a second load bearing platform


100


(in this case adapted to support a monitor) is mounted to first abutment means


11


(the upper plate) by means of a mounting post


102


spaced inwardly from edge connection


13


. Desirably mounting post


102


is provided with telescopic, airlift, or other height adjustment and may also be provided with swivel adjustment.





FIG. 11

shows the embodiment of

FIG. 10

when supporting a monitor on platform


100


, a keyboard on platform


30


and a mouse on upper plate


11


.





FIG. 12

shows an embodiment similar to that of

FIG. 10

but wherein keyboard support platform


30


is provided with a wrist support


103


.





FIG. 13

shows an embodiment wherein a monitor platform


100


is supported by a support pillar


102


from upper plate


11


of support means


1


. As shown in

FIG. 13

FIG. 14

, upper plate


11


may be provided with a wrist support


103


and the keyboard may be emplaced upon upper plate


11


.





FIG. 15

shows a further embodiment similar to that of

FIG. 14

but wherein mounting pillar


102


is provided with a laterally extending auxiliary platform


101


whereby a mouse may be supported. It will be appreciated that the embodiments of

FIGS. 13

,


14


and


15


share the same stability as embodiments earlier described in that the loads in each case tend to improve the grip between the support means and the desk.





FIG. 16

shows an embodiment in which a basket


104


and a task light


106


are supported via a pillar


102


from upper plate


11


. It will be understood that in each case pillar


102


may be made of adjustable length and horizontal support arms may be adjustable in height and radial direction from the pillar.





FIG. 17

shows an embodiment wherein a monitor support platform


100


is supported by a column


102


from a base plate


105


and wherein as shown in

FIG. 18

base plate


105


is clamped onto a desk top by means of support


1


engaging base plate


105


between upper plate


11


and the desk top.





FIG. 19

illustrates an alternative embodiment to those shown in

FIGS. 7 and 8

. The embodiment in

FIG. 19

includes an upper plate


85


integrally connected to a lower bent plate


86


via an intermediate portion


110


. The bent plate


86


includes a portion


86




a


disposed in a direction away from the upper plate


85


, and a portion


86




b


disposed in a direction towards upper plate


85


. Plates


85


and


86


are resiliently biased in a direction towards each other, and advantageously this embodiment will allow the desk accessory support


114


to be used in respect of the desk tops (not shown) of different thicknesses. Preferably rubber pads


111


are provided on the upper surface of the lower plate


86


in the vicinity of where portion


86




a


meets

Claims
  • 1. A desk accessory support for use with a desktop having an upper surface, a lower surface and an edge extending between the upper and lower surfaces, the support including:first abutment means for abutting the upper surface; second abutment means for abutting the lower surface, at least a portion of the second abutment means being resiliently displaceable away from at least a portion of the first abutment means such that said portions are biased towards each other for cooperatively gripping the desktop; connection means configured for connecting the first and second abutment means to each other and for being disposed adjacent to the edge when the first and second abutment means are in abutment with the upper and lower surfaces respectively; said first and second abutment means and said connection means defining a substantially U-shaped recess for receiving the edge of the desktop; at least one accessory being means connected to the second abutment means by means of a cantilevered coupling extending from the second abutment means so as to be at a distance from the edge in use; said cantilevered coupling adapted to allow adjustment of the position or orientation of the accessory bearing means with respect to the desk top; wherein a load applied to the accessory bearing means by an accessory carried thereon causes a moment on one of the first and second abutments means which urges at least a part of one of the first and second abutment means towards a part of the other abutment means, for causing deformation of at least one of the first and second abutment means and the connection means thereby to cause at least one of said parts more firmly to impinge upon the corresponding surface of the desktop to increase the grip of the first and second abutment means on the desktop.
  • 2. The desk accessory support of claim 1 wherein said connection means is effective for resiliently connecting the first and second abutment means to each other such that said abutment means are biased towards each other on being moved away from each other.
  • 3. The desk accessory support of claim 1 wherein the first abutment means includes a substantially planar upper surface, and the connection means includes a planar portion extending between the first and second abutments means, where in use, the connection means is disposed to abut a non linear edge of the desktop at two locations, and at least a portion of the first abutment means spans the region defined by the connection means and the portion of the non linear edge of the desktop between the two locations.
  • 4. The desk accessory support of claim 1 wherein the first and second abutment means include substantially parallel upper and lower planar fins respectively, which in use extend away from the edge and along at least a portion of the respective upper and lower surfaces.
  • 5. The desk accessory support of claim 1 wherein the first and second abutment means are substantially rectangular.
  • 6. The desk accessory support of claim 1 wherein the first and second abutment means are plates.
  • 7. The desk accessory support of claim 6 wherein the first and second abutment means are integrally formed plates.
  • 8. The desk accessory support of claim 1 wherein the first and second abutment means are releasably connected together.
  • 9. The desk accessory support of claim 1 wherein the first and second abutment means are adjustably spaced apart at a predetermined distance.
  • 10. The desk accessory support of claim 1 wherein the accessory bearing means is coupled to the second abutment means at a coupling position, by a cantilevered coupling extending, in use, at least partly in a direction from the coupling position to the edge, said moment causing said part of the second abutment means more firmly to impinge upon the lower surface.
  • 11. The desk accessory support of claim 10 wherein the cantilevered coupling includes a linkage assembly extending from a bracket assembly mounted to the second abutment means at the coupling position.
  • 12. The desk accessory support of claim 10 wherein the linkage assembly is a pantograph assembly.
