## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to computer mouse devices, and more specifically, to a computer mouse having a body with an ovoid palm support area and a planar peripherally receding support for the hypothenar mass and left and right anterior buttons eccentrically positioned askew the apex of the ovate form with one button located on a platform and elevated and angularly positioned relative to the other button that is substantially planar. The button platform could also be selectively movable along a limited distance of the anterior periphery of the body to allow a user to adjust the present invention to conform to different sized hands and fingers of varying lengths. The present invention is designed to elevate the wrist by supporting the palm so the hand is comfortably bent slightly downward and not in the unnatural upward angle with the wrist resting on the surface area thereby applying pressure thereto and affecting the related nerves and arteries passing through the underside of the wrist that is common in the prior art. The unnatural wrist flexion and pressure applied thereto combine with repeated activity of the flexor tendons and often result in repetitive stress disorders.

An ergonomic housing for a computer mouse helpful in minimizing the occurrence and alleviating the symptoms of repetitive strain injuries is disclosed. The mouse housing includes a palm support area having a hump which is an asymmetrically skewed bulge about with a user's hand may pivot. The palm support area also includes a tapered tail for supporting the hand and wrist off the surface. The housing includes at least one button which is elevated and angled to minimize flexion of and accompanying stress on the tendons of the finger. A thumb support is also provided to allow the thumb to rest off the surface and to aid in lifting the mouse.
A hand holdable computer mouse has a base, a top and a body. The base rests on a work surface and the body is vertically disposed above the base. The body has an external contour which substantially conforms to the mean of the contour of the palm side of the hand when the hand is in a relaxed, neutral condition, with the palm surface of the hand vertically oriented. The mouse is operated with the hand in a cupped, vertically oriented condition, with the wrist in a neutral condition with respect to radial and ulnar deviation, and with the forearm in a neutral condition.
A finger rest structure of computer mouse, including a housing having a profile substantially suitable for manual operation of a user and a finger rest unit including at least one rest plate transversely projecting from a lateral side of the housing for a finger to rest thereon. Two rest plates are respectively disposed on left and right sides of the housing near front and rear ends. Alternatively, the rest plate is integrally connected along the rear side and a part of lateral side of the housing. Alternatively, the rest plates are pivotally and foldably connected with the housing or disposed at two ends of a rotary plate which is rotatably disposed under the housing, whereby the rest plate can be selectively extended or retracted. The rest plate serves to bear most of the weight of the hand and reduce the frictional force of the hand against the table face. Also, the rest plate enlarges the bottom area of the mouse, whereby the mouse can more closely attach to the table face during moving and the control of the mouse is facilitated.
A computer mouse capable of stimulating therapeutic points of the human body to reduce user fatigue. Projection bodies for stimulating the therapeutic points are provided on the main body and click buttons of the computer mouse.
An improved ergonomic computer mouse is provided. The ergonomic mouse allows for the operator's hand to remain in a relaxed position in as near a state of repose as possible while operating the mouse. The shape of the mouse reduces several of the known high-risk postures during mouse use.
A multi-dimensional computer mouse includes a casing in which a circuit board is mounted. Left and right buttons are provided on a top of the casing for functioning as regular mouse push buttons. A third push button is arranged between the left and right buttons. A post extends from the third button to the circuit board. A spherical expansion is formed on a lower end of the post and rotatably received in a socket fixed on the circuit board for forming a joint allowing the post to be rotated from a neutral position to front and rear actuation positions wherein a collar of the post contacts and triggers a front contact switch and a rear contact switch. The post is floatingly supported by a spring arranged between the socket and the collar thereby allowing the post to be depressed against the spring for having the lower end of the post contact and trigger a bottom contact switch. Thus, a user is allowed to selectively trigger either one of the three contact switches for controlling a monitor cursor of a computer to which the mouse is coupled.
A mouse for use in association with a computer is disclosed. The mouse comprises a housing having a lower surface and an upper surface with side walls therebetween to define a lower chamber therewithin. The housing includes a peripheral extension wall extending upwardly from the periphery of the housing as an extension of the side walls to define an upper recessed cavity. A membrane having a periphery secured to the upper regions of the extension wall forms the top surface of a primary chamber. The membrane is fabricated of a deformable resilient elastomeric material. A quantity of gel-like fluid within the primary chamber is adapted to change shape of the housing membrane from an initial shape to a custom fit shape conforming substantially with the anatomical contours of a user's hand for enhanced comfort and reduced fatigue during use of the computer mouse, the gel-like fluid retaining the custom fit shape for a substantial period of time following release of the use of the computer mouse and thereafter returning substantially to the initial shape.
A hand-held mouse has a base pointing unit with a movement sensor and a plurality of switches for selecting a visual object indicated by a location of the graphical pointer on the display, and an outer shell surrounding and removably attached to the base pointing unit. A user has to purchase only one base computer mouse in order to accommodate other users. The shells are easily switched since the users do not have to unplug the base computer mouse to switch to a different computer mouse, and they are relatively inexpensive compared to purchasing completely separate computer mice. Different shells can be used with a common base computer mouse for different computer systems, and the outer shell might accordingly have a fewer number of buttons than there are switches on the base pointing unit.
An ergonomic computer mouse has support surfaces that are adjustable in two directions and that distribute the mechanical pressure points afforded by the mouse to the metacarpal region. The mouse has a housing with a proximal metacarpal support and a distal metacarpal support on its upper surface that are separated by a midsection. In use, the proximal end of the user's metacarpal hand region rests on the proximal metacarpal support, the distal end of the user's metacarpal hand region rests on the distal metacarpal support, and the remainder of the user's metacarpal hand region between their proximal and distal ends span the midsection. The mouse may further include a pivot mechanism that couples an upper and lower portion of the mouse housing together. The pivot mechanism may allow a user to adjust the upper and lower housing portions in pitch and roll directions with respect to one another.
An ambidextrous upright computer mouse includes a relatively upright finger engaging side on one side, and a thumb engaging side on an opposite side. Two sets of buttons are positioned at opposite ends of the finger engaging side. The mouse is symmetrical about a vertical transverse medial plane. When the finger engaging side is on the right side, the mouse can be grasped by a right hand. When the mouse is rotated so that the finger engaging side is on the left side, it can be grasped by the left hand. There is always a set of buttons at the forward end of the mouse, regardless of its orientation. Only one set of buttons is enabled at any time. The sets of buttons are alternately enabled and disabled by moving a selector switch. Ambidexterity is provided without compromising feel and comfort for either hand.
While these ergonomic mouse devices may be suitable for the purposes for which they were designed, they would not be as suitable for the purposes of the present invention, as hereinafter described.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The following discussion describes in detail one embodiment of the invention and several variations of that embodiment. This discussion should not be construed, however, as limiting the invention to those particular embodiments, practitioners skilled in the art will recognize numerous other embodiments as well. For definition of the complete scope of the invention, the reader is directed to appended claims.
Turning to FIG. 1, shown therein is a perspective view of the prior art in use depicting a woman user 12 using a conventional computer 14 and mouse 6 and demonstrating the unnatural positioning of the users fingers 18 and wrist 20 when using such a mouse 16. The wrist 20 is resting on the surface 22 thereby applying pressure thereto as the hand 24 is bent upward subjecting the user 12 to prolonged wrist flexion, two actions which could conjuntively cause the compression of the medial nerve and result in a repetitive stress disorder. The risk of such disorders increase because many prior art mouse 16 designs require the buttons to be pressed by the fingertips demanding the flexion of all three finger joints and the repetitive use of the related flexor tendons.
Turning to FIG. 2, shown therein is an enlarged view of a user using a conventional computer mouse 16 taken from FIG. 1 as indicated demonstrating the unnatural positioning of the user's fingers 18 and wrist 20 when using such a mouse. The wrist is resting on the surface 22 thereby applying pressure thereto as the hand 24 is bent upward so that the palmar arch and the first and second fingers are on top of the mouse, the thumb along one side and the third and fourth fingers on the other side. The ulnar and median nerves run through the underside of the wrist to the hand as do the ulnar and radial arteries which supply blood to the five digits. The pressure applied to the underside of the wrist combined with the bent wrist could affect the nerves and restrict the blood supply to the hand. The median nerve supplies cutaneous branches to the thumb and the first and second fingers with the two fingers susceptible to repetitive movement disorders from continuously pressing the mouse buttons. The median nerve is particularly vulnerable to pressure applied to the underside of the wrist and the lower palm because its recurrent branch (motor branch) lies superficially therein.
Turning to FIG. 3, shown therein is a palmar view of a human hand 24 approximating the location of the median nerve 26, the ulnar nerve 28, the radial artery 30, the ulnar artery 32 and the thenar 34 and hypothenar regions 36 of the palm.
Turning to FIG. 4, shown therein is a perspective view of the present invention 10, an ergonomic mouse 10 having an ovate palm support 38 with an integral left click button 40 a hypothenar support platform 42 and a raised arcuate right button 44 on a substantially planar platform 46. The palm of the hand rests on the apex of the ovate palm support 38 so the wrist bends slightly downward with the curvature of the mouse 10 body thus relieving the stress placed upon the related flexor tendons. The weight of the hand is distributed throughout the meaty part of the palm against the ovate palm support 38 so as to relieve the pressure that the prior art places against the bent wrist area and its critical tendons, nerves and arteries.
Turning to FIG. 5, shown therein is a top view of the present invention 10 showing elements previously disclosed.
Turning to FIG. 6, shown therein is a side view of the present invention 10 showing elements previously disclosed along with the mouse ball 48 conventionally disposed on the flat underside of the mouse 10.
Turning to FIG. 7, shown therein is a perspective view of the present invention 10 with the user's hand 24 resting on the arcuate, ovate palm support on the body of the mouse 10. The hypothenar region of the hand and the pinky 50 and ring 52 fingers are resting on the hypothenar platform. The index 54 finger rests on the left button 40 in such a manner that pressure application from any joint of the appendage will activate the button 40. The right button 44 protrudes from the right button platform 46 so that a sweeping motion of the middle 56 finger from any direction will act upon the button 44. The thumb 58 is shown along with other elements previously disclosed.
Turning to FIG. 8, shown therein is a top view of the present invention 10 having a rotatable, locking right button platform 46 that would allow a user to configure the placement of the right button 44 relative to the left button 40 and the hypothenar platform 42 to conform to the shape and finger length of different users' hands. The ovate palm support 38 is also shown.
Turning to FIG. 9, shown therein is a top view of the present invention 10 adapted for use by left-handed people wherein the left button 60 resides on the platform 62 adjacent the hypothenar platform. The right button 64 is shown along with other elements previously disclosed. The right button 64 is shown along with other elements previously disclosed.
Turning to FIG. 10, shown therein is a perspective view of a left-handed version of the present invention 10. Other elements previously disclosed are also shown.
Turning to FIG. 11, shown therein is a top view of a left-handed version of the present invention 10. Other elements previously disclosed are also shown.
Turning to FIG. 12, shown therein is side view of a left-handed version of the present invention 10. Other elements previously disclosed are also shown.
Turning to FIG. 13, shown therein is a perspective view of the present invention 10 in use with the user's palm resting on the arcuate, ovate palm support on the body of the mouse 10. The hypothenar region 36 of the hand and the pinky and ring fingers are resting on the hypothenar platform 42. The index finger rests on the right button 64 in such a manner that pressure application from any joint of the appendage will activate the button. The left button 60 protrudes from the left button platform 62 so that a sweeping motion of the middle finger from any direction will act upon the button. Thumb 58 is also shown.
Tuning to FIG. 14, shown therein is a top view of a left-handed version of the present invention 10 with a rotatable, locking left button platform 62 that allows a user to configure the placement of the left button 60 relative to the right button 64 and the hypothenar platform 42 to conform to the shape and finger length of different users' hands. The ovate palm support 38 is also shown.
