Abstract

A computer pad is heated for reducing repetitive motion stress and increasing comfort for a user and for providing potential therapeutic treatment by warming the hand(s) and/or wrist(s) of the user while operating a computer input device such as a mouse or a keyboard. The pad includes an electrical heating device such as a resistance-type heating element embedded in it. If a mouse is used as the input device, it can be either a stationary mouse or a conventional movably positioned mouse that is operated on the level section of the top surface of the pad'"'"'s upper layer. If a stationary mouse or a keyboard is utilized, the user'"'"'s hand(s) and/or wrist(s) can be supported by a suitably shaped area within an elevated section of the working surface of the pad. The lower layer of the pad may conveniently include a non-skid bottom surface. Conventional electrical controls such as, for example, a rheostat and/or thermostat are used to achieve and maintain the desired temperature range, and a standard, 120v electrical power outlet is employed as the power source. A heated computer apparatus comprises a computer keyboard and heating device that is close to the input device and the hand(s) and/or wrist (s) of the computer user. A computer keyboard is manually operated through a repetitive motion by the user, while at least a portion of the user'"'"'s hand(s) and/or wrist(s) is heated to relieve stress induced by the repetitive motion.

Claims

1. A heated computer pad which reduces. repetitive motion stress and increases comfort for a user and which provides potential therapeutic treatment by warming at least a portion of a user'"'"'s hands and wrists while operating computer input means, comprising:

an upper layer and a lower layer;

a working surface on said upper layer, said working surface having a forward and a rearward end, said working surface being planar at said forward end, said planar working surface at said forward end being adapted to receive said computer input means thereon, said rearward end having an elevated portion adapted to support at least a portion of a user'"'"'s hands and wrists;

four peripheral edges, each having a substantially uninterrupted surface;

electrical means for heating said pad, said electrical means being connected to an electrical power cord that extends from the surface of only one of said peripheral edges; and

control means associated with said electrical means for providing appropriate heat regulation and power thereto.

2. A heated computer pad according to claim 1, wherein said pad is adapted to receive computer input means selected from the group consisting of a keyboard and a mouse.

3. A heated computer pad according to claim 1, wherein said electrical means comprises resistive heating wire, said wire being situated in said lower layer and being connected to an electrical power source.

4. A heated computer pad according to claim 1, wherein said control means comprises a rheostat.

5. A heated computer pad according to claim 1, wherein said control means comprises a thermostat.

6. A heated computer pad according to claim 1, wherein said control means comprises a switch.

7. A heated computer pad according to claim 1, wherein said lower layer of said pad includes a non-skid bottom surface for engagement with a supporting surface.

8. A heated computer pad according to claim 1, wherein said electrical means and said control means provide for heating said working surface of said pad to a temperature above room temperature but below the temperature that will cause burning of the skin of a user.

9. A heated computer pad according to claim 8, wherein the temperature of said working surface is about 90°

C. to 106°

C. (32°

to 41°

C.).

10. A heated computer pad according to claim 1, wherein said upper layer is made of a fabric material.

11. A heated computer pad according to claim 10, wherein said fabric material is a vinyl fabric or a canvas fabric.

12. A heated computer pad according to claim 1, wherein said lower layer is made of a rubber material.

13. A heated computer pad according to claim 1, wherein said working surface at said rearward end is configured as an elevated area.

14. A heated computer pad according to claim 13, wherein said elevated area includes a depression dimensioned and configured for supporting at least a portion of a user'"'"'s hands and wrists.

15. A heated computer input apparatus which reduce, repetitive motion stress and increases comfort for a user and which provides potential therapeutic treatment for at least a portion of a user'"'"'s hands and wrists, while operating the apparatus, comprising:

a computer keyboard for inputting data to a computer by repetitive operation;

heating means proximate said computer keyboard and proximate the at least a portion of a user'"'"'s hands and wrists and which heats at least a portion of a user'"'"'s hands and wrists to reduce stress incurred by repetitive operation of said computer keyboard.

16. The heated computer input apparatus according to claim 15, wherein said heating means comprises a heated pad for supporting at least a portion of a user'"'"'s wrists, said heated pad comprising:

an upper working surface;

a non-skid bottom surface;

four peripheral edges, each having a substantially uninterrupted surface; and

an electrical heating element incorporated in the pad and provided with an electrical power cord that extends from the surface of only one of said peripheral edges.

17. A process for inputting data to a computer which simultaneously treats stress to a least a portion of a computer user'"'"'s hands and wrists resulting from repetitive motion by a user, comprising:

manually operating a computer keyboard that is operated by a repetitive motion by a user, and heating at least a portion of a user'"'"'s hands and wrists during said operating of said computer keyboard.

18. A process according to claim 17, wherein at least a portion of a computer user'"'"'s hands and wrists is heated at a temperature high enough to relieve stress induced by the repetitive motion of operating said computer keyboard.
