Description
I 16629~
BACKGROUND OF T~IE INVENTION
This inven-tion rela-tes generally -to a suppor~t mernber to be interposed between a computer terminal, elec-tric -typewri-ter or other piece of office equipment and the equipmen-t operator, and which is also interposed between a -table -top, desk top or the like and -the equipment.
In -the use of computer terminals and other electric office equipmen-t, -there are usually time in-tervals when the hands of the operator are not on the keyboard such as when the operator is waiting for a command or instruction from -the computer. Because the key-boards of computers are extremely sensitive to touch, it is impera-tive that the opera-tor's hand be completely removed from the key-board during these intervals.
~ Ieretofore, it has been the prac-tice for the computer operator's hands to be moved su*ficien-tly far from the keyboard, such as being placed on the lap of the computer opera-tor, as -to create a substantial loss of efficiency when the computer opera-tor's hands are then placed back on the keyboard. Prior to the present invention, -there has been no suitable hand rest prov-ided for compu-ter terminals or other types of office equipment.
In addition, i-t is well known that a computer opera-tor may develop a static charge which can cause a substantial shock when the operator touches the compu-ter equipment. There are also instances where the draining of the static charge from the computer operator -to the computer result in an erroneous response f`rom the compu-ter and/or damage to -the computer circui-try.
Various techniques have been developed for draining the static charge from the compu-ter operator such as a sui-table grounded conductive pad on the desk top or a suitably grounded conduc-tive pad on the floor underneath the feet of the compu-ter oper~-tor. Mos-t of these mechanisms are unacceptable because of their appearance and difficulty of use. The difficulty of use is that a delibera-te effort must be made to -touch the conduc-tive pad prior to touching the equipmen-t -to obtain the benefit of a s-ta-tic discharge.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference to Figures 1, 2, 3 and 4 there is illustra-ted a computer terminal keyboard or o-ther -type of elec-tric office equipment 10 positioned on the top of a desk of table 12, having a Eront or forward edge 13. Interposed between the computer terminal and the desk 12 is the preferred embodiment of -the compu-ter terminal support 14 of -the presen-t invention. The computer terminal 10 may include a keyboard 16 and -thus the present inven-tion may be utilized with all types of office equipmen-t including keyboards such as computer terminals, adding machines, typewriters and o-ther types of word processing equipment~
With further reference to -the drawings, -the computer terminal support 14 of Figures 1-4 includes a first section which is to be interposed between the compu-ter -terminal and the desk top.
2~9 lis first section comprises -two -thin, fla-t elongated members 18 which may be made of a plas-tic ma-terial. Each of these fla-t members 18 includes, at a first end, a plurality of apertures 20 -to receive screws therethrough so that -the flat members 18 may be fastened -to the underside of -the computer terminal keyboard 10. Figure 3 illustrates these flat members 18 at-tached to -the underside of the computer terminal keyboard 10. The computer terminal keyboard 10 usually includes a plurality of downwardly depending fee-t 22 and the flat members 18 which comprise the first section of -the compu-ter terminal support are illustrated as being positioned inwardly of these feet 22. The flat members 18 may be joined under the key-board and may include a non-slip surface material.
The preferred embodimen-t of the computer terminal support also includes a second section attached to the first section 18 of the support. In the preferred embodiment this second section includes an e]ongated tubular member 2l~, also preferably formed of plastic, around which is secured a conductive means 26. In the preferred embodiment, the conductive means does not extend -the full length of the tube 24. Preferably the conductive means may be a conductive material such as Velcro-type loop fastening material sold under -the trade mark HI-MEG. HI-MEG VELCR0 refers to a hook and 1QP type fastening medium which is electrically conductive.
As illustrated in Figure 3, the conductive means 26 is connected by a short length of wire 28 to a current limiting resis-tor 30. The other side of the resistor 30 is connected by a wire 32 to a sui-table ground to provide for static charge drain for -the opera-tor. The grounding wire 32 is shown as being separate and distinct from the computer power line 3Li -to indicate that the conductive means is not grounded to the keyboard circuit ground bu-t to a primary power ground such as tha-t found a-t a wall outle-t. This avoids -the crea-tion of a ground loop. In a preEerred embodiment the short length of wire 28 is s-tanded copper wire wi-th the s-trands fanned out and secured to the conduc-tive means 26. The conductive means 26 is adhesively secured around ~the tube 24.
6~
In use, -the suppor-t lLI of the presen-t irlven-tiorl is shown as being interposed be-tween -the compu-ter -terminal keyboard and the top of a desk 12. When an opera-tor is sitting at the desk 12 to utilize the compu-ter -terminal keyboard, the suppor-t of the presen-t invention is also interposed be-tween -the computer terminal opera-tor and the computer terminal and the second section or tube 24 of the support thus provides for drain of any static charge on -the compu-ter terminal opera-tor. In addition, the conductive means and -tube pro-vide a convenient resting place for the hands of the computer opera-tor during periods of non-use of the computer terminal and further-more, the wrists of the computer terminal opera-tor may rest on -the support while the operator is actually using the compu-ter terminal keyboard. Finally, it may be appreciated that since the compu-ter terminal support 14 is secured to the computer terminal keyboard uni-t, the support also functions as a handle so that the keyboard unit may be carried -to other loca-tions.
Having thus described the preferred embodiment of the present invention, reference should now be had to Figures 5 and 6 of the drawings for an explana-tion of an al-ternate embodimen-t of the present invention. In Figures 5 and 6 -the compu-ter terminal support is illustra-ted as having a generally fla-t firs-t section 36 which is interposed between the cornputer terminal 10 and the top of the desk 12. As is the case in the embodiment of Figures 1-4, -the fla-t section of the computer terminal support of Eigures 5 and 6 extends generally parallel to the top of the desk and inwardly of -the forward edge 13 of the desk. The first or flat section also extends out-wardly of -the forward edge of -the desk -toward -the computer operator.
The flat section 36 is curved back upon i-tself -toward -the computer terminal and at a slight upwardly incline to define d second se¢tion 38. This second section 38 provides a rest for -the hands of -the computer opera-tor during periods of non-use of -the computer terminal and also a res-ting place for the compu-ter -terminal operator's wrists when the hands or fingers of -the compu-ter opera-tor are on the keyboard.
6~9 The second sec-tion 38 oF the compu-ter -terminal suppor-t terminates in an upwardly opening U-shaped -trough 40 which provides a convenient resting place for -the fingers of the computer operator during periods of non-use of the computer terminal and also provides a receptacle for pens, pencils, erasers and the like. That portion of the U-shaped trough 40 which is closest to the compu-ter terminal is a generally vertical wall 42 against which -the leading edge of the computer terminal may be aligned. In the embodiment of Figures 5 and 6 -the flat first section 36 of the support includes a plurality of apertures 44 through which the fee-t 22 of the computer terminal may extend and -thus be in conect wi-th the table top. By the provi-sion of these apertures 44, the computer terminal is retained in a level position on the table top rather than having the fron-t portion of -the computer terminal elevated slightly because of -the thickness of -the flat section of the computer terminal support.
In the embodiment of Figures 5 and 6 conductive means 46 are provided to allow for the drain of static charge from the computer operator. Specifically, gold plated grounding wires are embedded in the surface of the second sec-tion 38 of the computer terminal support. These gold plated grounding wires are connected by a wire 28 to a resistor (not shown in Figures 5 and 6) and then to a power ground as described with respect to the prior embodimen-t.
The conductive material 26 of Figures 1-4 may be used in the embodi-ment of Figures 5 and 6 in place of the grounding wires 46.
Referring next to Figures 7 and 8 yet another embodiment of -the present invention is illustrated. The embodiment of Figures 7 and 8 provides for a relatively permanent attachment of the support 14 to the desk 12. To accomplish this objective, the computer terminal support 14 of Figures 7 and 8 includes a flat f;rs-t section 50 which is shorter than -the corresponding flat section 36 of the embodimen-t of Figure 6. The fla-t first sec-tion of -the computer support 14 of Figures 7 and 8 is also curved back upon itself on a slight upward incline -to define a second section which also includes a U-shaped -trough corresponding -to the embodiments '7 ~ ~æ6~
~_ Figures 5 and 6. Conduc-tlve rneans such as -the gr-ounding wire or conductive ma-t may also be provided.
With respect to the embodimen-t of Figures 7 and 8, instead of apertures for the fee-t of the computer terminal, -the edges of -the flat first section 50 are provided with a series of apertures 52 through which suitable screws may extend. Angle brackets 54 are provided and the angle brackets, which include apertures for fasten-ers, are secured both to the flat sec-tion 50 of the support and -the fron-t of the desk 12.
Thus according to the embodimen-t of Figures 7 and 8, the computer terminal suppor-t may be permanently secured to angle brackets which angle brackets in turn are permanently secured to the fron-t of ~the desk 12. In this embodiment, the front vertical wall 42 of the U-shaped trough provides a surface against which the front of the compu-ter terminal may be aligned. Tha-t is, -the computer terminal may be moved so that the fron-t edge of the computer terminal is in abutting contac-t wi-th the vertical wall 42 of the support member.
Since the -terminal support may be formed by extrusion, the side-to-side width may be increased to permit a plurali-ty of terminals to be aligned along the forward edge of a counter-type work surface.
Referring next to Figures 9-12, still another embodiment of the present invention is illus-trated. In the embodiment of Figures 9-12, the computer terminal support 14 includes a fla-t first section 56 which is to be interposed between the computer terminal and the top of the desk 12. Optionally, a plurality of pads 58 of non-marring, non-s]cid ma-terial such as felt may be provided on -the underside of the flat section 56. Non-skid material of the type described is commercially available with an adhesive ma-terial on one side so that such ma-terial may(be adhesively secured -to -the compu-ter terminal suppor-t.
The firs-t sec-tion of the compu-ter terminal support of Figures 9-12 is therafter cur-ved to define a second section which is of generally Z-shaped configuration and, in the preferred ) ~6~9 , nbodiment, is in-tegrally formed wi-th the Eirs-t sec-tion 56. Thus the second sec~ion 60 of -the computer terminal support includes a first vertical portion 62 which extends upwardly from the plane of the flat section 56 and then curves back into an inclined por-tion 64. The inclined portion 64 is angled downardly and forwardly relative to the first flat section 56 and is -thereafter curved back upwardly to form a second vertical portion 66. The first vertical portion 62, the inclined por-tion 64 and the second vertical portion 66 comprise the Z-shaped section 60 of -the computer terminal support and the first and second ver-tical portions are parallel -to each other. The second vertical portion extends upwardly to the plane of the fla-t first section 56 and is -then curved to extend forwardly as a hori~ontal extension 68 parallel to and in -the same plane as the flat first section 56.
In the embodiment of Figures 9-12, the flat first section 56 of the computer terminal support is interposed between the computer terminal 10 and the top of the desk 12. The fr-ont edge of the computer -terminal may be abutted against the first vertical portion 62 of the computer terminal support. The entire computer terminal support may be moved so that the forward corner 13 of the desk 12 abu-ts and aligns against the underside of the inclined portion 64. Thus the inclined portion 64 provides a posi-tive stop for aligning the support relative to the desk 12. The hands of the computer terminal operator may be rested either on the horizon-tal extension 68 or alternatively at -the intersection of the inclined portion and the firs-t vertical por-tion. Furthermore, the area be-tween -the inclined portion 64 and the second vertical portion 66 provides a trough for storage of pens, pencils~ erasers and the like.
The upper surface of por-tion 64 and ex-tension 68 may carry conduc-tive means such as the grounding wires or means 26 as previously described.
The foregoing is a comple-te explana-tion of -the various embodiments of the presen-t inven-tion. In -the embodiments of Figures 1-4, the flat section as well as -the second sec-tion including -the tube 24 may be integrally formed of p]astic, acrylic, plexiglass, _g_ 1 .t6~2Y9 , lypropylene or similar ma-teria1 or may op-tionally be Eorrned as separate members secured -toge-ther. In -the embodimen-ts oF Figures 5-12 it is preferred -that -the computer -terminal suppor-t be formed as a unitary integral struc-ture of plastic, acrylic, plexiglass, polypropylene or similar material. However, i-t must be appreciated that the various sections may be separately made. In any even-t, it is preferred that where the flat first section and the second section meet, there be a suitable curving rather than a sharp edge and similarly the Z-shaped por-tion of the embodiment of Figures 9-12 should be suitably curved or rounded ra-ther than sharp edges to ensure operator safety.
Furthermore, in all embodiments, conductive means of either wire or conductive mat-like material may be used. In all embodi-ments where the support rests on the desk top, non-marring, non-skid pads may be used.
It should thus be appreciated tha-t many changes may be made wlthout departing from the spirit and scope of -the presen-t invention. The present invention, -therefore, should be limited only by the following claims.
The preferred embodimen-t of the computer terminal support also includes a second section attached to the first section 18 of the support. In the preferred embodiment this second section includes an e]ongated tubular member 2l~, also preferably formed of plastic, around which is secured a conductive means 26. In the preferred embodiment, the conductive means does not extend -the full length of the tube 24. Preferably the conductive means may be a conductive material such as Velcro-type loop fastening material sold under -the trade mark HI-MEG. HI-MEG VELCR0 refers to a hook and 1QP type fastening medium which is electrically conductive.
As illustrated in Figure 3, the conductive means 26 is connected by a short length of wire 28 to a current limiting resis-tor 30. The other side of the resistor 30 is connected by a wire 32 to a sui-table ground to provide for static charge drain for -the opera-tor. The grounding wire 32 is shown as being separate and distinct from the computer power line 3Li -to indicate that the conductive means is not grounded to the keyboard circuit ground bu-t to a primary power ground such as tha-t found a-t a wall outle-t. This avoids -the crea-tion of a ground loop. In a preEerred embodiment the short length of wire 28 is s-tanded copper wire wi-th the s-trands fanned out and secured to the conduc-tive means 26. The conductive means 26 is adhesively secured around ~the tube 24.

In use, -the suppor-t lLI of the presen-t irlven-tiorl is shown as being interposed be-tween -the compu-ter -terminal keyboard and the top of a desk 12. When an opera-tor is sitting at the desk 12 to utilize the compu-ter -terminal keyboard, the suppor-t of the presen-t invention is also interposed be-tween -the computer terminal opera-tor and the computer terminal and the second section or tube 24 of the support thus provides for drain of any static charge on -the compu-ter terminal opera-tor. In addition, the conductive means and -tube pro-vide a convenient resting place for the hands of the computer opera-tor during periods of non-use of the computer terminal and further-more, the wrists of the computer terminal opera-tor may rest on -the support while the operator is actually using the compu-ter terminal keyboard. Finally, it may be appreciated that since the compu-ter terminal support 14 is secured to the computer terminal keyboard uni-t, the support also functions as a handle so that the keyboard unit may be carried -to other loca-tions.
Having thus described the preferred embodiment of the present invention, reference should now be had to Figures 5 and 6 of the drawings for an explana-tion of an al-ternate embodimen-t of the present invention. In Figures 5 and 6 -the compu-ter terminal support is illustra-ted as having a generally fla-t firs-t section 36 which is interposed between the cornputer terminal 10 and the top of the desk 12. As is the case in the embodiment of Figures 1-4, -the fla-t section of the computer terminal support of Eigures 5 and 6 extends generally parallel to the top of the desk and inwardly of -the forward edge 13 of the desk. The first or flat section also extends out-wardly of -the forward edge of -the desk -toward -the computer operator.
The flat section 36 is curved back upon i-tself -toward -the computer terminal and at a slight upwardly incline to define d second se¢tion 38. This second section 38 provides a rest for -the hands of -the computer opera-tor during periods of non-use of -the computer terminal and also a res-ting place for the compu-ter -terminal operator's wrists when the hands or fingers of -the compu-ter opera-tor are on the keyboard.
6~9 The second sec-tion 38 oF the compu-ter -terminal suppor-t terminates in an upwardly opening U-shaped -trough 40 which provides a convenient resting place for -the fingers of the computer operator during periods of non-use of the computer terminal and also provides a receptacle for pens, pencils, erasers and the like. That portion of the U-shaped trough 40 which is closest to the compu-ter terminal is a generally vertical wall 42 against which -the leading edge of the computer terminal may be aligned. In the embodiment of Figures 5 and 6 -the flat first section 36 of the support includes a plurality of apertures 44 through which the fee-t 22 of the computer terminal may extend and -thus be in conect wi-th the table top. By the provi-sion of these apertures 44, the computer terminal is retained in a level position on the table top rather than having the fron-t portion of -the computer terminal elevated slightly because of -the thickness of -the flat section of the computer terminal support.
In the embodiment of Figures 5 and 6 conductive means 46 are provided to allow for the drain of static charge from the computer operator. Specifically, gold plated grounding wires are embedded in the surface of the second sec-tion 38 of the computer terminal support. These gold plated grounding wires are connected by a wire 28 to a resistor (not shown in Figures 5 and 6) and then to a power ground as described with respect to the prior embodimen-t.
The conductive material 26 of Figures 1-4 may be used in the embodi-ment of Figures 5 and 6 in place of the grounding wires 46.
Referring next to Figures 7 and 8 yet another embodiment of -the present invention is illustrated. The embodiment of Figures 7 and 8 provides for a relatively permanent attachment of the support 14 to the desk 12. To accomplish this objective, the computer terminal support 14 of Figures 7 and 8 includes a flat f;rs-t section 50 which is shorter than -the corresponding flat section 36 of the embodimen-t of Figure 6. The fla-t first sec-tion of -the computer support 14 of Figures 7 and 8 is also curved back upon itself on a slight upward incline -to define a second section which also includes a U-shaped -trough corresponding -to the embodiments '7 ~ ~æ6~
~_ Figures 5 and 6. Conduc-tlve rneans such as -the gr-ounding wire or conductive ma-t may also be provided.
With respect to the embodimen-t of Figures 7 and 8, instead of apertures for the fee-t of the computer terminal, -the edges of -the flat first section 50 are provided with a series of apertures 52 through which suitable screws may extend. Angle brackets 54 are provided and the angle brackets, which include apertures for fasten-ers, are secured both to the flat sec-tion 50 of the support and -the fron-t of the desk 12.
Thus according to the embodimen-t of Figures 7 and 8, the computer terminal suppor-t may be permanently secured to angle brackets which angle brackets in turn are permanently secured to the fron-t of ~the desk 12. In this embodiment, the front vertical wall 42 of the U-shaped trough provides a surface against which the front of the compu-ter terminal may be aligned. Tha-t is, -the computer terminal may be moved so that the fron-t edge of the computer terminal is in abutting contac-t wi-th the vertical wall 42 of the support member.
Since the -terminal support may be formed by extrusion, the side-to-side width may be increased to permit a plurali-ty of terminals to be aligned along the forward edge of a counter-type work surface.
Referring next to Figures 9-12, still another embodiment of the present invention is illus-trated. In the embodiment of Figures 9-12, the computer terminal support 14 includes a fla-t first section 56 which is to be interposed between the computer terminal and the top of the desk 12. Optionally, a plurality of pads 58 of non-marring, non-s]cid ma-terial such as felt may be provided on -the underside of the flat section 56. Non-skid material of the type described is commercially available with an adhesive ma-terial on one side so that such ma-terial may(be adhesively secured -to -the compu-ter terminal suppor-t.
The firs-t sec-tion of the compu-ter terminal support of Figures 9-12 is therafter cur-ved to define a second section which is of generally Z-shaped configuration and, in the preferred ) ~6~9 , nbodiment, is in-tegrally formed wi-th the Eirs-t sec-tion 56. Thus the second sec~ion 60 of -the computer terminal support includes a first vertical portion 62 which extends upwardly from the plane of the flat section 56 and then curves back into an inclined por-tion 64. The inclined portion 64 is angled downardly and forwardly relative to the first flat section 56 and is -thereafter curved back upwardly to form a second vertical portion 66. The first vertical portion 62, the inclined por-tion 64 and the second vertical portion 66 comprise the Z-shaped section 60 of -the computer terminal support and the first and second ver-tical portions are parallel -to each other. The second vertical portion extends upwardly to the plane of the fla-t first section 56 and is -then curved to extend forwardly as a hori~ontal extension 68 parallel to and in -the same plane as the flat first section 56.
In the embodiment of Figures 9-12, the flat first section 56 of the computer terminal support is interposed between the computer terminal 10 and the top of the desk 12. The fr-ont edge of the computer -terminal may be abutted against the first vertical portion 62 of the computer terminal support. The entire computer terminal support may be moved so that the forward corner 13 of the desk 12 abu-ts and aligns against the underside of the inclined portion 64. Thus the inclined portion 64 provides a posi-tive stop for aligning the support relative to the desk 12. The hands of the computer terminal operator may be rested either on the horizon-tal extension 68 or alternatively at -the intersection of the inclined portion and the firs-t vertical por-tion. Furthermore, the area be-tween -the inclined portion 64 and the second vertical portion 66 provides a trough for storage of pens, pencils~ erasers and the like.
The upper surface of por-tion 64 and ex-tension 68 may carry conduc-tive means such as the grounding wires or means 26 as previously described.
The foregoing is a comple-te explana-tion of -the various embodiments of the presen-t inven-tion. In -the embodiments of Figures 1-4, the flat section as well as -the second sec-tion including -the tube 24 may be integrally formed of p]astic, acrylic, plexiglass, _g_ 1 .t6~2Y9 , lypropylene or similar ma-teria1 or may op-tionally be Eorrned as separate members secured -toge-ther. In -the embodimen-ts oF Figures 5-12 it is preferred -that -the computer -terminal suppor-t be formed as a unitary integral struc-ture of plastic, acrylic, plexiglass, polypropylene or similar material. However, i-t must be appreciated that the various sections may be separately made. In any even-t, it is preferred that where the flat first section and the second section meet, there be a suitable curving rather than a sharp edge and similarly the Z-shaped por-tion of the embodiment of Figures 9-12 should be suitably curved or rounded ra-ther than sharp edges to ensure operator safety.
Furthermore, in all embodiments, conductive means of either wire or conductive mat-like material may be used. In all embodi-ments where the support rests on the desk top, non-marring, non-skid pads may be used.
It should thus be appreciated tha-t many changes may be made wlthout departing from the spirit and scope of -the presen-t invention. The present invention, -therefore, should be limited only by the following claims.
