Description

WORK SURFACE WITH A FLEXIBLE EDGE

RELATED APPLICATIONS

This application is a continuation-in-part of U.S. Application Serial No. 07/872,933, filed on April 22, 1992, the entire disclosure of which is incorporated herein by reference.

BACKGROUND OF THE INVENTION

The present invention relates generally to work surfaces. More particularly, the invention relates to a work surface to which a flexible edge is secured to provide a more comfortable and ergonomic work surface. Many occupations require support for the palm, forearm or elbow of a worker on the edge of a work surface. For example, people involved in telephone sales must often spend many hours resting an elbow or forearm on a rigid work surface. Similarly, people working with a computer on a work surface may spend many hours resting the base of their palms on a rigid work surface. It has been found that prolonged contact with a rigid work surface, aside from being uncomfortable, may also lead to repetitive strain injuries such as carpal tunnel syndrome, ulnar nerve entrapment and other nerve entrapment disorders.

Various structures have been employed to create a comfortable arm rest. For example, U.S. Patent No. 3,300,250 to R.W. Dollgener issued on January 24, 1967, discloses a cushioned support to be applied to the edge of a table or desk. The arm rest has a base member that is attached by an adhesive to the exposed surface of a table or bench. The base extends from a position above the work surface and overhangs the vertical edge of the table or bench. The base member may be comprised of aluminum or other suitable metal or plastic. A cushion of foam rubber or other suitable material is arranged over the arcuate surface of the base member. A cover of pliable material extends over the surface of the cushion and is secured into grooves within the base member by extruded plastic strips.

SUMMARY OF THE INVENTION This invention is directed to a work surface for use by a worker positioned adjacent the work surface. In accordance with one aspect of the invention, the work surface includes a primary work section having a top surface, a bottom surface, a front edge adjacent the worker and an arm support member. The arm support member is connected to the edge of the primary work section and extends outward therefrom in a direction toward the worker. At least a portion of the arm support member is made from a resilient material, whereby the application of downward force by the worker's arms causes at least a portion of the arm . support member to bend downward to provide a comfortable support for a worker's arms resting thereon. In a preferred embodiment of the invention, the arm support member is comprised of a resilient section and a rigid edge member. The resilient section has a downwardly directed groove that extends the length thereof. The groove provides the edge member with a larger range of motion.

In another preferred embodiment of the invention, the arm support member has an inflatable bladder and an inflation means. The inflation means acts to increase the pressure within the bladder whereby the stiffness and/or the shape of the arm support member may be adjusted to the particular requirements of a worker.

With the foregoing in mind, it is a feature and advantage of the present invention to provide a work surface having an improved support for the wrists, elbows, and forearms of user allowing for more comfortable. posturing at the work surface. The present work surface provides a comfortable surface for those performing typing, writing or reading tasks. Moreover, it also an advantage of the present invention to provide a passive surface in case of accidental contact with the surface.

In another aspect of this invention, the work surface is comprised of a primary work section and a resilient section. The primary work section has a top surface, an edge, and a slot extending inward from an edge of the primary work section. The slot should be sized to allow a wire and a plug to pass therethrough. The resilient section has an edge adapted to be connected to at least a portion of the edge of the primary work section. The resilient section further includes a recess cover portion substantially covering the slot of the primary work section. An aperture is defined by the recess cover portion and is sized to allow a wire to pass therethrough. Thus, a wire may pass through the aperture in the recess cover portion of the resilient section into the slot of the primary work section and down under the work surface, thereby providing a secure wire-holding assembly.

In a further aspect of the invention, an adjustable work surface is provided having a first work section, a second work section and a hinge member.

The first work section has a top surface defining a plane, a bottom surface and a first edge. The second work section has a top surface defining a plane, a bottom surface and a first edge. The hinge member is connected to the first edge of the first work section and the first edge of the second work section. The hinge member is made from a resilient material in order to allow the first work section and the second work section to be angularly positioned relative to one another.

In still another aspect of the invention, an adjustable work surface is provided having a first work section, a second work section, a third work section, a first hinge member, and a second hinge member. The first work section has a top surface defining a plane, a bottom surface, a front edge adjacent the worker and a back edge. The second work section has a top surface defining a plane, a bottom surface, a first edge and a second edge. The third work section has a top surface defining a plane, a bottom surface and a first edge. The first hinge is connected to the back edge of the first work section and the first edge of the second work section. The second hinge section is connected to the second edge of the second work section and the first edge of the third work section. The first and second hinges are made from a resilient material whereby the first work section, the second work section and the third work section may be angularly positioned relative to one another. The present invention, together with attendant objects and advantages, will be best understood with reference to the detailed description below, read in conjunction with the accompanying drawings.

A

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The work surface with a flexible edge of the present invention 5 includes surfaces such as are found on desks, benches, tables, keyboard trays or other similar articles. The work surface is sized to allow a worker to use the surface with a work implement such as a computer, telephone, pen and paper or the like. Materials such as particle board with a high pressure laminate, wood, plastic, paper, metal or other similar materials may be used to construct the work 10 surface.

FIGURE 1 shows a first embodiment of the work surface of the present invention. A work surface 10 includes a primary work section 12 and an arm support member 14 having a resilient section 16 and a rigid edge member 18. The primary work section 12 is the top of a desk or other similar work surface. 15 Preferably, in this embodiment and the below described embodiments, the arm support member has a thickness approximately equal to the thickness of the primary work section. However, the actual thickness may be varied by correspondingly changing the materials used to make the arm support member. In particular, a stiffer material is necessary if the arm support member is decreased 20 in thickness.

In the present embodiment, the primary work section 12 is composed of particle board with a top laminate section 22 defining a top substantially planar surface of the primary work section 12 and a bottom laminate section 24 defining a bottom substantially planar surface of the primary work ^* 25 section 12. The top laminate section 22 and the bottom laminate section 24 may be composed of materials such as wood, high pressure laminates such as formica or other materials.

The primary work section 12 has an edge 26 that is angled inward from the top laminate section 22 with a groove 28. Preferably, the resilient section 16 is molded to the edge 26 of the primary work section 12 and runs therealong. However, the arm support member 14 may be attached to the edge 26 using many different methods of attachment known to those of ordinary skill in the art such as mechanical attachment using a screw, a bolt or the like. Moreover, the arm support member 14 may be removably attached to edge of a work section by using a releasable clamping mechanism or Velcro^®. In the following embodiments, the arm support member may be attached using any of the above- described methods.

Preferably, the resilient section 16 is composed of a resilient, flexible material including rubber compounds, foams such as self-skinning foams, elastomers, plastics such as polyurethane, or other materials possessing similar properties. In the following embodiments, the resilient materials described above may be used. The top surface 27 of the resilient section 16 extends flush with the primary work section 12 and the edge member 18. The resilient section 16 has two outwardly and oppositely extending tongues 29 and 30. The tongue 29 mates with the groove 28 of the primary work section 12. The edge member 18 has a groove 32 that mates with tongue 30.

The resilient section 16 of this embodiment defines a downwardly- directed groove 34. The groove 34 is an inverted V-shape in cross-section and provides additional flexibility to the edge member 18. However, as will be seen in the below-described embodiments, it is recognized that various groove configurations may be used such as an inverted U-shape in cross-section, an inverted rectangular shape, a sawtooth shape, a multiple inverted U-shape in cross- section, or other similar configurations. The edge member 18 projects outward from the resilient section 16 and runs therealong. The edge member 18 is composed of wood, although it is recognized that other materials may be used such as plastics, particle board with a laminate, extruded plastics or other materials known to those skilled in the art. The edge member 18 projects outward from a plane defined by the top laminate section 22 and slopes downward and slightly curves inward into the plane defined by the bottom laminate section 24.

In operation, a worker adjacent the arm support member 14 of the work surface 10 would use the surface in conjunction with a work implement such as a computer, telephone, pen and paper or the like. As the worker used the work implement such as a computer keyboard placed on the primary work section 12, the base of his palm would create a downward force on the arm support member 14. Similarly, a worker using a telephone could rest his elbows on the arm support member 14 creating a downward force. In the present and below described embodiments, the arm support member 14 may also support other parts of the human body such as hands, forearms or wrists. In both of these situations, the arm support member 14 will deform to match a worker's elbows, hands, forearms or wrists thereby providing a more comfortable work surface as well as preventing nerve entrapment injuries. Upon removal of the worker's palm or elbow, the arm support member 14 will return to its original aesthetic appearance because of the resilient nature of the arm support member 14. Similarly, the embodiments of this invention disclosed in FIGURES 2-32 may be used in the same way.

FIGURE 10 shows a tenth embodiment of the work surface of this invention. A work surface 260 includes a primary work section 262 and an arm support member 264. The primary work section 262 may be formed from wood or other materials known to those skilled in the art. The primary work section 262 has a top surface 266, a bottom surface 268 and an edge 270. The top surface 266 is a substantially planar surface. The arm support member 264 is molded onto the edge 270 and projects outward therefrom. The arm support member 264 slopes downward from a plane defined by the top surface 266 of the primary work section 262 and curves inward into the plane defined by the bottom surface 268 of the primary work section 262. The arm support member 264 projects outward a sufficient length to support the palm, forearm or the elbow of a worker positioned adjacent the arm support member 264. For example, a width of approximately 4 inches and a thickness of approximately 1 inch are desirable dimensions. However, the arm support member 264 may be easily sized to the particular requirements of a user. Grooves 272 are located in the upper surface of the arm support member 264 to provide a decorative visual appearance. An upwardly projecting ridge may also be provided in the arm support member of this invention in order to prevent papers from slipping off the work surface. Preferably, the arm support member 264 is comprised of a resilient material as described above.

In the present embodiment, the arm support member 264 is connected to a flat edge 270 on the primary work section 262. However, as shown in the above-described embodiments, the arm support member may be attached to a wide variety of edge configurations. For example, FIGURE 10A shows the embodiment of FIGURE 10 with the primary work section 275 having an angled edge 276 attached to an arm support member 278. Moreover, if a material is choosen having a very low durometer, a support plate or stiffener 279 made from plastic or metal may be either molded into the arm support plate or separatly attached to the arm support member. By varying the relative durometer of the arm support and support plate, a wide range of flexability may be achieved. FIGURES 10B and IOC show another embodiment of the present invention, wherein the resiliency of the arm support jnember can be adjusted.

This embodiment includes at least one adjustment block 907 which is adapted to slide within the cavity 909 formed in the primary work surface 903 and the cavity 911 formed within the arm support member 905. The adjustment block 907 is preferably made from a rigid material, such as wood, metal or plastic. Alternatively, the adjustment block 907 is formed from a resilient material such as rubber or polyurethane, with the provision that the adjustment block is more stiff than the arm support member.

For maximum flexibility of the arm support member, the adjustment block 907 is pushed all the way back into the cavity 909 in the primary work surface. For maximum stiffness of the arm support member, the adjustment block 907 is pulled all the way forward into the cavity 911 of the arm support member. The position of the adjustment block 907 is locked in place. Preferably, this is accomplished by including an adjustment knob 913 which includes a threaded portion 917 which passes through a slot 915 in the primary work surface and into a threaded hole 919 in the adjustment block. To make an adjustment of the flexibility of the arm support member, the knob is loosened and the block is slid into the desired position. The knob is then tighten to maintain the block in that position.

FIGURE IOC shows the preferred embodiment wherein more than one adjustment block is used to adjust the arm support member. In particular, three blocks 911, 921 and 923 are included. In this way, the flexibility of the arm support member can be adjusted at these three positions to best accommodate the needs of a particular user. As shown, the block 921 is shown in the fully retracted position, thus giving maximum flexibility of the arm support member at that location. The block 923 is shown in its fully extended position to thereby give the maximum stiffness to the arm support member at that location. The block 911 is shown extended about halfway.

In the alternative embodiment shown in FIGURE 10D, there is only a single adjustment block 931, which is wider than those shown in Figure 10B. In this embodiment, the single adjustment block 931 is used to adjust the flexibility of the entire arm support member 934. Also, because of its increase width, this embodiment uses more than one adjustment knob to secure its position.

FIGURE 11 shows an eleventh embodiment of the work surface of the present invention. A work surface 280 includes a primary work section 282 and an arm support member 284 having a resilient section 286 and a rigid edge member 288. The primary work section 282 may be formed from wood or other materials known to those skilled in the art.

The edge member 288 is connected to the resilient section 286. The edge member 288 is curved in order to be securely bonded to the resilient section 286. Although the edge member 288 is composed of wood, other materials as described above are within the scope of this invention.

FIGURE 12 shows a twelfth embodiment of the work surface of the present invention. A work surface 300 includes a primary work section 302 and an arm support member 304 having a resilient section 306, a first rigid edge member 308 and a second rigid edge member 310.

Similarly, the resilient section 306 interconnects the second edge member 310 to the second edge 314 of the primary work section 302. The resilient section 306 has a corner section 316 adapted to interconnect the first edge member 308 and the second edge member 310. The corner 316 has an accordion shape to allow the first edge member 308 to be directed downward by a worker without affecting the positioning of the second edge member 310. The edge members 308 and 310 may be constructed from wood or other suitable materials known to those skilled in the art.

FIGURE 13 shows a thirteenth embodiment of the work surface of the present invention. A work surface 320 includes a primary work section 322 and an arm support member 324. The arm support member 324 has a resilient section 326 and a middle section 328 and an end section 330.

FIGURE 14 shows an embodiment of the work surface of this invention wherein a wire access channel is provided. A work surface 350 is composed of a primary work section 352 and an arm support member 354. The primary work section 352 has a laminate top surface 356, an edge 358 and a slot

360. The slot 360 is of sufficient size to allow an electrical wire to pass therethrough. The arm support member 354 is bonded onto the edge 358 of the primary work section 352. The arm support member 354 has a recess cover portion 362 that extends into the slot 360. The recess cover portion 362 defines an aperture 364 of sufficient size to allow a wire to pass therethrough.

FIGURE 15 shows a fourteenth embodiment of the work surface of the present invention. The work surface 370 includes a primary work section 372 and an arm support member 374. The primary work section 372 may be formed from wood or other materials known to those of ordinary skill in the art.

The arm support member 374 is connected to an edge 376 of the primary work section 372. In the present embodiment, the arm support member 374 may be made entirely from a resilient material as described above. However, because the arm support member 374 is relatively thin (0.25 inches), a relatively high durometer material such as a foam or elastomer can be used. A foam backing may also be used with the present embodiment. There is a general relationship between the thickness of the arm support member and the resiliency of the material used. Accordingly, if the thickness of the arm support member is reduced, a material having less resiliency can be used. Similiarly, a foam backing can be used to increase the stiffness of the arm support member.

FIGURE 22 shows a perspective view of a twenty-first embodiment of the work surface of the present invention. In the present embodiment, the work surface 600 is adjustable and has multiple levels. A first work surface 602 has a primary work section 604 and an arm support member 606. The primary work section 604 has a generally horizontally extending surface having an arcuate shaped front edge 608 and back and side edges 610 forming a curved pocket therein. The primary work section 604 is sized to support a keyboard thereon although the primary work section 604 could be sized for use with a wide variety of work implements.

The arm support member 606 is at least connected to the front edge 608 and may extend around the back and side edges 610. The arm support member 606 has an uneven thickness that creates a soft pocket or contour 612 generally following the shape of the front edge 608 of the primary work section 604. A worker may be positioned within the contour 612 when using the work surface 600. In particular, the contour 612 allows a worker to comfortably rest his elbows on the arm support member 606. The arm support member 606 may be made entirely from a resilient material as described above.

A second work surface 620 is connected to the first work surface 602 by a conventional keyboard support mechanism 630. The second work surface 620 is sized to support a computer monitor. Both the primary work section 604 and the second work surface 620 may be formed from wood or other materials known to those of ordinary skill in the art.

The first work surface 602 is movable both laterally and vertically. The first work surface 602 is movable in a lateral direction by the action of a conventional keyboard support mechanism 630. The support mechanism 630 is attached to a second work surface 620 in order to provide for movement of the first work surface 602 relative to the second work surface 620. The laterally adjustable support mechanism 630 may be those known to ordinary skill in the art to provide for the lateral movement of keyboard trays and the like.

The second work surface 620 also has a conventional vertically movable support column 640 attached thereto. Accordingly, the first work surface 602 is also vertically movable. The support column 640 provides for the vertical adjustment of the second work surface 620 and the attached first work surface 602. A wide variety of vertically adjustable support mechanisms such as mechanical spring cylinders, pneumatic cylinders, mechanical or motorized rack- and-pϊnϊon type mechanisms and other support mechanisms known to those of ordinary skill in the art may be used to vertically adjust the work surface 600.

Furthermore, the support mechanisms shown in U.S. Patent No. 3,285,207 to Heinz-Gunter Muller Vom Hagen and in U.S. Patent No. 4,381,714 to Henneberg et al., the disclosures of which are incorporated herein, may be easily configured to adjust the height of the work surface 600. FIGURE 23 shows a perspective view of a twenty-second embodiment of the work surface of the present invention. In the present embodiment, the work surface 650 has multiple levels. A first work surface 652 has a primary work section 654 and an arm support member 656. The primary work section 654 has a generally horizontally extending surface having an arcuate shaped front edge 658 and back and side edges 660 forming an angled pocket therein. The primary work section 654 is sized to support a keyboard thereon. However, the primary work section 654 could also be sized for use with a wide variety of work implements as described above.

The arm support member 656 is at least connected to the front edge 658 and may extend around the back and side edges 610. The arm support member 656 has an uneven thickness that creates an angled pocket or contour 662. A worker may be positioned within the contour 662 when using the work surface 650. In particular, the contour 662 allows a worker to comfortably rest his elbows on the arm support member 656. The arm support member 656 may be made entirely from a resilient material as described above.

The first work surface 652 is fixedly secured to the second work surface 670 by conventional bracket or the like. However, the second work surface 670 may also be connected to the first work surface 652 by a movable keyboard support mechanism. The second work surface 670 is sized to support a computer monitor thereon. A third work surface 672 is fixedly attached above the second work surface 670. The third work surface 672 has two separated portions that would partially enclose a computer monitor resting on the second work surface 670. Both the second work surface 670 and third work surface 672 are connected to base wall 680 by conventional support brackets or similar mounting methods. The primary work section 654, the second work surface 670 and third work surface 672 may be formed from wood or other materials known to those of ordinary skill in the art.

FIGURES 24-27 show a twenty-third embodiment of the work - surface of this invention having an inflatable bladder. A work surface 675 includes a primary work section 676 and arm support member 677 having an inflatable bladder 678. The primary work section 676 has an irregularly shaped edge 679 attached to the arm support member 677. A support plate 679 extends beneath the bladder 678. The support plate 679 is attached to the primary work section 676 by a screw. The support plate made from one piece or two separate pieces joined togeather. Materials such as plastics or metals may be used to form the support plate.

The arm support member 677 is attached to the edge 679 and projects outward a sufficient length to support the palm, forearm or elbow of a worker positioned adjacent the support member 677. As best shown in FIGURES 26-27, the arm support member 677 is formed having a bladder 678 and a smaller secondary bladder 680. The secondary bladder 680 acts to inflate the bladder 678 as described below. Ridges or other markings may be provided on the exterior surface of the arm support member 677 thereby indicating the location of the secondary bladder 680. An inlet valve 681 acts to open and close the inlet channel 682 which provides access to an exterior fluid source such as air. However, it is within the scope of this invention to also use conventional liquids. The inlet valve 681 is made from a ball bearing 683 and a spring 684.

An interior valve 685 is adjacent an interior channel 686 that connects the secondary bladder 680 to the bladder 678. The interior valve 685 is also made from a ball bearing 687 and a spring 688. In both the inlet valve 681 and interior valve 685, the spring forces the ball bearing against the opening in the channel to thereby seal the channel.

A deflation valve 690 is attached to a bottom surface 691 of the arm support 677. The deflation valve 690 allows a fluid to pass from the bladder 678 thereby decreasing the pressure therein. A spring 692 forces the angled stop member 693 to securely fit within the sides of the deflation channel 694.

The arm support member 677 of the present embodiment is preferably molded from a resilient material such as an elastomer. However, other materials including foams, plastics and rubber compounds may also be used. In the molding process, an access portion should be formed to allow for the placement of the inlet valve 681, the interior valve 685 and the deflation valve 690. The access portion should then be sealed by conventional methods such as bonding or heat sealing.

In operation, a worker adjacent the work surface 675 adjusts the stiffness and shape of the arm support member 677 by inflating the bladder 678.

By depressing the arm support member 677 above the secondary bladder 680, the secondary bladder 680 is compressed forcing a fluid such as air into the bladder 678. In particular, the pressure within the secondary bladder 680 overcomes the force created by the spring 688 pressing against the ball bearing 686. Accordingly, the ball bearing 686 is pushed back to allow the fluid to pass through the interior channel 686 into the bladder 678. Because the fluid is forced into the bladder 678, the pressure within the bladder 678 increases thereby increasing the stiffness of the arm support member 677. After the worker releases the pressure on the secondary bladder 680, the secondary bladder 680 fills with the fluid from an external fluid source. In particular, the internal pressure within the secondary bladder 680 creates a suction pulling the external fluid through the inlet channel 682 and past the inlet valve 681. If desired, a worker could continue to raise the pressure within the bladder 678 until the shape of the arm support member 677 is deformed as shown in FIGURE 25. As for deflation, by pushing upward on the deflation valve 690, the angled neck portion of the stop member 693 is disengaged from the sides of the deflation channel 694 thereby allowing fluid to escape the bladder 678. An open cell foam may be placed inside the bladder 678 to prevent the collapse of the bladder when the fluid is released from the bladder 678. It should be recognized that a variety of inflation mechanisms could be used. In particular, a completely separate inflation mechanism such as an external secondary bladder could be used to increase the pressure within the primary bladder. Moreover, it should be also be recognized that the arm support member 677 may be contructed in such a manner that the resiliency of the arm support member 677 and the shape of the arm support member 677 may be separately or jointly adjustable. The arm support 677 may also be constructed to allow for a wide variety of changes in shape.

FIGURE 28 shows a safety edge membsr that may be used in ^• combination with the work surface of the present invention when adjacent a secondary work surface. The work surface 695 includes a primary work section

696 having a safety edge member 697 molded thereto. The primary work section 696 has side edges 698 having an irregular cutout with the safety edge 697 attached thereto. The safety edge 697 has a relatively thin (approximately 0.25 inches) outwardly extending portion 698. In general, materials such as rubber compounds, foams, elastomers, plastics or other materials possessing similar properties may be used to manufacture the safety edge 697.

The safety edge 697 functions to protects a worker's fingers when the work surface 695 is movable relative to a secondary work surface 699. If a worker's fingers were resting over an edge 700 of the secondary work surface when the work section 695 was being moved relative to the secondary work surface 699, the worker's fingers would not risk injury because of the resilient nature of the safety edge 697. In particular, as shown in shadow in FIGURE 28, the safety edge 697 would bend rather than directly hit the fingers of the worker. Moreover, the safety edge 697 provides for an increased work surface area. FIGURE 29 shows a perspective view of a twenty-fourth embodiment of the work surface of the present invention. The adjustable work surface 701 has a first work section 702 and a second work section 704 interconnected by a flexible hinge 706. The first work section 702 and the second work section 704 are angularly adjustable relative to one another. Accordingly, the work surface 701 may be used with a computer to allow for the relative adjustment of a keyboard and a monitor. Alternatively, the work surface 701 may be used while in a planar position.

The first work section 702 has a generally trapezoid-like shape and is sized to support a keyboard thereon. The first work section 702 has a first edge 710 having two curved end portions 712 interconnected by a linear portion 714.

The second work section 704 has a generally triangular shape and is sized to support a computer monitor thereon. Both the first work section 702 and the second work section 704 may be formed from wood or other materials known to those of ordinary skill in the art. An arm support member 720 is connected to the edge 712 of the first work section 702 and extends therealong. The arm support member 720 has a first curved end portion, a second curved end portion and a linear intermediate portion extending between the first end portion and the second end portion. The arm support member 720 may be made entirely or partially from a resilient material as described above.

A flexible hinge 706 is connected to a second edge 722 of the first work surface 702 and a first edge 724 of the second work surface 704. The hinge 706 is molded onto the first work surface 702 and the second work surface 704. A downwardly directed groove, as shown in FIGURES 1-3 and 13 may be provided in order to give the hinge greater flexibility. Apertures 730 may also be provided to allow a wire to pass therethrough. The apertures may also be located adjacent an outer edge of the hinge with a slit extending from the aperture to the outer edge. The hinge 706 is made from a resilient material as described above. Conventional support apparatus known to those of ordinary skill in the art may be used to support the work surface 701. For example, the first work surface 702 could be fixedly secured to an adjacent wall. A rod having a threaded portion and a handle would be attached to the lower surface of the first work surface 702 and the second work surface 704. A stationary swivel bearing would secure the end of the rod having the handle to the lower surface of the first work surface 702. A swivel nut assembly having at least one groove would secure the threaded portion of the rod to the lower surface of the second work surface 704. A worker could rotate the handle thereby rotating the rod. Accordingly, depending upon the rotation of the rod, the second work surface is tilted up or down relative to the first work surface 702 as the threaded portion of the rod rotates through the swivel nut assembly.

FIGURES 30-31 show an adjustable work surface having a twenty- fourth embodiment of the work surface of the present invention. The adjustable work surface 800 has a first work section 802 and a second work section 804 interconnected by a first flexible hinge 806. The work surface 800 further includes a third work section 810 interconnected to the second work section 804 by a second flexible hinge 812. The first work section 802, the second work section 804 and the third work section 810 are angularly adjustable relative to one another. Accordingly, the work surface 800 may be used with a computer to allow for the relative adjustment of a keyboard and a monitor on the first work section 802 and the third work section 810 respectively. Moreover, the second work surface 804 may provide support for reading or typing materials. Alternatively, the work surface 800 may be used while in a planar position as shown in FIGURE 31.

The first work section 802, the second work section 804 and the third work section 810 have a generally rectangular shape. The first work section

802 has a slightly curved first edge 820 and an opposite linear second edge 822. The second work section 804 has a linear first edge 830 and a parallel second edge 832. The second work section 804 is slightly smaller than the first work section 802. The third work section 810 is slightly larger than the first work section 802 and has a linear first edge 840. The first work section 802, the second work section 804 and the third work section 810 may be formed from wood or other materials known to those of ordinary skill in art.

An arm support member 850 is connected to the edge 820 of the first work section 802 and extends therealong. The arm support member 850 has an uneven thickness that creates an angled pocket or contour 852. However, the. arm support member 850 may also form a curved pocket as well. A worker may be positioned within the contour 852 when using the work surface 800. In particular, the contour 852 allows a worker to comfortably rest his elbows on the arm support member 800. The arm support member 850 may be made entirely from a resilient material as described above.

The first hinge 806 is connected to a second edge 822 of the first work section 802 and a first edge 830 of the second work section 804. The second hinge 812 is connected to the second edge 832 of the second work section 804 and the first edge 840 of the third work section 810. Both hinges 806 and 812 are molded onto their corresponding work sections. Moreover, the hinges 806 and 812 are made from a resilient material as described above.

A downwardly directed groove 860 may be provided in order to give the hinges 806 and 812 greater flexibility. The groove may be shaped similar to the grooves shown in FIGURES 1-3 and 13. Apertures may also be provided to allow a wire to pass through the hinges 806 and 812. The apertures may also be located adjacent an outer edge of the hinge with a slit extending from the aperture to the outer edge.

FIGURE 32 shows a fragmentary perspective view of a conventional adjustment mechanism for use with the adjustable work surface of FIGURES 29-31. A wheel 860 having a gear 862 is rotatable by a worker in order to provide for the adjustment of the work surface. A drive gear 862 fits within the wheel 860 and rotates therewith. The drive gear 862 translates the rotation of the wheel 860 into rotation of the rod 866. A first bevel gear 868 extends from the end of the rod 866 opposite the drive gear 862. A second bevel gear 870 mates at a 90 degree angle with the first bevel gear 868. A worm gear 872 extends from the second bevel gear 870 and mates with axial cylinder gear 880. The rotation of the axial cylinder 880 causes the rotation of the shaft 882 and the clevis 884. The clevis 884 is attached by a support bracket 886 and a mounting plate 888 to the work surface 890. Accordingly, the rotation of wheel 860 is translated through the gearing mechanism shov/n into an upward or downward movement of the work section 890. Similar, co-axial mechanisms may be used to provide for the adjustment of additional work sections. Moveover, other conventional mechanical and motorized adjustment mechanisms known to those of ordinary skill in the art may be used. The embodiments described above are illustrative and not restrictive. The scope of the invention is indicated by the claims rather than by the foregoing description. The invention may be embodied in other specific forms without departing from the spirit of the invention. Accordingly, all changes which come within the scope of the claims are intended to be embraced therein.
