Abstract
Abstract A finger, hand and arm muscle exerciser having a horizontal base plate with a stanchion post extending upwardly from the back edge. A horizontal cross-bar extends forwardly from the top of the post and has a coil spring hung from it along a vertical axis which intersects a central portion of the base plate for stability. A hand grip, generally similar in appearance to a bicycle handlebar grip, and made of a squeezable rubber-like material, is hung from the bottom of the spring to a position spaced sufficiently above the base plate to allow room for downward movement of the hand grip against the bias resistance of the spring. In use, the exerciser is placed on a horizontal surface such as a table or desk top. The user grasps the hand grip between the fingers, palm and thumb. Then, sqeezing forces are applied sequentially to the hand grip by the individual fingers, starting with the first or forefinger and ending with the fourth or little finger while simultaneously pulling the hand grip downwardly toward the base plate against the bias of the spring and maintaining the elbow braced against the table or desk top surface adjacent the base plate.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
145 words
A finger, hand and arm muscle exerciser comprising: a base having a horizontal bottom surface for support on a table or desk top or the like in use; a stanchion including a post extending upwardly from the base; a coil spring suspended at the top end from the stanchion at a location spaced above the base about a vertical axis intersecting the base inside the horizontal margins thereof to provide stability therefor when pulled downwardly; an elongated hand grip suspended vertically from the bottom end of the spring and terminating above the base to enable downward displacement by a pull on said spring; whereby the exerciser may be operated by grasping the hand grip and applying squeezing forces to the hand grip by the user's individual fingers in sequence while simultaneously pulling the hand grip downwardly during said sequence against the bias of the spring.
Claim 2
Dependent Claim
145 words
A finger, hand and arm muscle exerciser comprising: a base having a horizontal bottom surface for support on a table or desk top or the like in use; a stanchion including a post extending upwardly from the base; a coil spring suspended at the top end from the stanchion at a location spaced above the base about a vertical axis intersecting the base inside the horizontal margins thereof to provide stability therefor when pulled downwardly; an elongated hand grip suspended vertically from the bottom end of the spring and terminating above the base to enable downward displacement by a pull on said spring; whereby the exerciser may be operated by grasping the hand grip and applying squeezing forces to the hand grip by the user's individual fingers in sequence while simultaneously pulling the hand grip downwardly during said sequence against the bias of the spring.
Claim 3
Dependent Claim
48 words
An exerciser according to claim 1 in which the base is a plate, the stanchion includes a post extending upwardly from an off-center portion of the plate and a crossbar extending horizontally from the post, and the coil spring is a tension spring suspended from said horizontal cross-bar.
Claim 4
Dependent Claim
40 words
An exerciser according to claim 1 in which the hand grip has four external protuberances spaced vertically apart and defining finger-receiving indentations to facilitate downward pull against the spring while applying said sequence of squeezing forces by the individual fingers.
Claim 5
Dependent Claim
25 words
An exerciser according to claim 3 in which the surface portion of the hand grip including the protuberances is made of a squeezable, rubberlike material.
Claim 6
Independent Claim
91 words
A method of exercising a user's finger, hand and arm muscles comprising the steps of: (a) suspending a hand grip from a spring to a position closely adjacent a horizontal surface; (b) bracing the user's elbow on the horizontal surface while grasping the grip between the finger, palm and thumb of the corresponding hand; and (c) applying squeezing forces to the hand grip by the individual fingers in sequence while simultaneously pulling the hand grip downwardly against the bias of the spring and maintaining the elbow biased against the horizontal surface.
Claim 7
Independent Claim
91 words
A method of exercising a user's finger, hand and arm muscles comprising the steps of: (a) suspending a hand grip from a spring to a position closely adjacent a horizontal surface; (b) bracing the user's elbow on the horizontal surface while grasping the grip between the finger, palm and thumb of the corresponding hand; and (c) applying squeezing forces to the hand grip by the individual fingers in sequence while simultaneously pulling the hand grip downwardly against the bias of the spring and maintaining the elbow biased against the horizontal surface.
