Abstract

A computer mouse includes a gliding base and a side wall extending upwardly therefrom in a closed, curved shape such as a cylinder. The cylinder width is dimensioned to be grasped between the thumb and opposed fingers of the hand. A concave grip extends about the side wall, the concavity complementary to the curved fingertip surfaces grasping the mouse. Switches are located in the grip under the grasping fingers, so that “click” inputs are made without moving the grasping fingers. Additional switches may be placed in the dome-like top panel spanning the upper opening of the side wall. One switch may provide a clutch function to block screen cursor movement while the mouse is slidably returned to a convenient user position. The mouse cable exits from the top panel to define a slack loop that minimizes drag on the mouse.

Claims

1. A computer mouse assembly, including:

a gliding base and a side wall extending upwardly from said base;

said side wall forming a closed curved configuration, said configuration being dimensioned to be grasped between the thumb and opposed fingers of a user'"'"'s hand;

switch means for receiving user inputs and generating switch click signals;

mouse tracking means disposed within said side wall for generating mouse movement signals; and

,

means for transmitting said mouse movement signals and said switch click signals to a computer system.

2. The computer mouse of

claim 1

, wherein said side wall includes an outer grip surface formed circumferentially thereabout, said outer grip surface extending concavely radially inwardly with respect to the radius of said closed curved configuration.

3. The computer mouse of

claim 1

, wherein said switch means includes at least one switch secured to said side wall.

4. The computer mouse of

claim 3

, wherein said at least one switch is disposed beneath one of the grasping fingers of the hand of the user, whereby said at least one switch may be actuated without movement of the finger.

5. The computer mouse of

claim 1

, further including a top panel spanning an upper opening of said side wall.

6. The computer mouse of

claim 5

, wherein said switch means includes at least one top switch extending from said top panel.

7. The computer mouse of

claim 5

, wherein said means for transmitting includes a cable connected from said mouse to a computer system, said cable having a proximal end extending from said top panel, said cable describing a semi-loop above a surface supporting said gliding base to minimize drag on said mouse.

8. The computer mouse of

claim 5

, wherein said top panel includes an upper surface extending convexly upwardly.

9. The computer mouse of

claim 1

, further including a flange-like skirt extending radially outwardly, said skirt having a radial extent greater than the radial extent of said closed curved configuration of said side wall.

10. The computer mouse of

claim 1

, wherein said gliding base includes a base panel extending parallel to the mouse supporting surface, and a plurality of gliding feet extending from said base panel to impinge on the mouse supporting surface.

11. The computer mouse of

claim 1

, wherein said mouse tracking means includes a central opening in said gliding base, a ball disposed within said side wall, a portion of said ball extending through said central opening to impinge and roll on the mouse supporting surface.

12. The computer mouse of

claim 11

, said mouse tracking means further including a pair of shafts extending mutually perpendicularly, means for mounting said pair of shafts to contact said ball, said pair of shafts being rotated by said ball as it rolls on the mouse supporting surface, a pair of shaft encoder disks, each mounted on a respective one of said shafts, each encoder disk including a high resolution reticule formed by photographic printing.

13. The computer mouse of

claim 6

, wherein said at least one top switch comprises a membrane switch.

14. The computer mouse of

claim 6

, wherein said at least one top switch is lighted internally.

15. The computer mouse of

claim 6

, wherein said switch means further includes at least one side wall switch secured to an exterior portion of said side wall.

16. The computer mouse of

claim 15

, wherein said at least one side wall switch is disposed beneath one of the grasping fingers of the hand of the user, whereby said at least one side wall switch may be actuated without movement of the finger.

17. The computer mouse of

claim 15

, wherein said at least one side wall switch and said at least one top switch are connected in parallel.

18. The computer mouse of

claim 15

, wherein said side wall includes an outer grip surface formed circumferentially thereabout, said outer grip surface extending concavely radially inwardly with respect to the radius of said closed curved configuration.

19. The computer mouse of

claim 18

, wherein said at least one side wall switch is disposed beneath said outer grip surface and secured to said closed curved side wall.

20. The computer mouse of

claim 19

, further including a plurality of said side wall switches mounted in adjacent fashion on said closed curved side wall and disposed to be actuated by the fingers of the user'"'"'s hand.

21. The computer mouse of

claim 6

, wherein said at least one top switch includes a switch ball having a portion protruding upwardly through said top panel.

22. The computer mouse of

claim 21

, further including a membrane switch disposed to receive force transmitted from said switch ball.

23. The computer mouse of

claim 22

, further including a circuit board disposed within said closed curved side wall, said membrane switch mounted on said circuit board.

24. The computer mouse of

claim 14

, further including means for selectively illuminating said at least one top switch in response to command signals from a computer connected to said mouse.
