Abstract
Abstract A hand exerciser includes a frame having a contoured hand grip portion and a slide mechanism supported within the frame for reciprocative movement. The slide mechanism includes a transverse finger grip which is both rotatable and angled to maximize the contact area between the palm of the hand and the finger grip. Springs are positioned between the frame and the slide mechanism to provide the resistive force necessary. The resistive force may be adjusted by a single internally threaded knob which cooperates with an externally threaded fastening element between the frame and the slide mechanism. A mechanical counter is coupled to the frame and is engaged by the slide element for the purpose of counting the number of strokes. Also provided is a pointer and scale mechanism for indicating the amount of resistive force provided by the springs.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
247 words
A hand exerciser, comprising: a frame having a contoured hand grip portion; a slide mechanism supported within said frame for reciprocative movement therein including a slide element for supporting a finger grip and an insert element, said insert element being slidably received by said slide element, said slide element including a first plurality of support means in a lower portion thereof and a second plurality of support means in an upper portion thereof, said finger grip being rotatable on a rod having the ends thereof positioned by any one of said first plurality of support means and any one of said second plurality of support means, said first and second pluralities of support means being aligned with the direction of reciprocation so as to enable a stroke distance between said contoured hand grip portion and said finger grip to be varied and depending upon what first and second support means are utilized to vary the angle of said finger grip portion with respect to said hand grip portion resilient means coupled between said frame and said slide mechanism for resisting movement between said frame and said slide mechanism and resisting the insertion of said insert element into said slide element; and adjusting means for varying the resistance of the resilient means between said frame and said slide mechanism including an adjustment element extending between said slide element and said insert element and means coupled to said adjustment element for manually adjusting the resistance of said resilient means.
Claim 2
Dependent Claim
247 words
A hand exerciser, comprising: a frame having a contoured hand grip portion; a slide mechanism supported within said frame for reciprocative movement therein including a slide element for supporting a finger grip and an insert element, said insert element being slidably received by said slide element, said slide element including a first plurality of support means in a lower portion thereof and a second plurality of support means in an upper portion thereof, said finger grip being rotatable on a rod having the ends thereof positioned by any one of said first plurality of support means and any one of said second plurality of support means, said first and second pluralities of support means being aligned with the direction of reciprocation so as to enable a stroke distance between said contoured hand grip portion and said finger grip to be varied and depending upon what first and second support means are utilized to vary the angle of said finger grip portion with respect to said hand grip portion resilient means coupled between said frame and said slide mechanism for resisting movement between said frame and said slide mechanism and resisting the insertion of said insert element into said slide element; and adjusting means for varying the resistance of the resilient means between said frame and said slide mechanism including an adjustment element extending between said slide element and said insert element and means coupled to said adjustment element for manually adjusting the resistance of said resilient means.
Claim 3
Dependent Claim
51 words
A hand exerciser according to claim 1 wherein said finger grip comprises: a grip element having a bore therethrough through which said rod passes and protrudes at both ends thereof, each protruding end for positioning in one of said first and second plurality of support means, said support means being apertures.
Claim 4
Dependent Claim
44 words
A hand exerciser according to claim 1 wherein said slide element has an indicating portion formed thereon for cooperating with a scale on said insert element to indicate the amount of resistance between said frame and said insert element imparted by said resilient means.
Claim 5
Dependent Claim
30 words
A hand exerciser according to claim 3 further comprising a counter coupled on said frame and engaged by said slide mechanism to count the number of strokes of said exerciser.
Claim 6
Dependent Claim
59 words
A hand exerciser according to claim 1 wherein said resilient means comprises at least one spring assembly each comprising: a spring mounting rod having a first end fixedly coupled in said frame and a second end cooperating with said insert element; and a spring positioned on said spring mounting rod and compressed between said frame and said insert element.
Claim 7
Dependent Claim
17 words
A hand exerciser according to claim 5 wherein said resilient means comprises first and second spring assemblies.
Claim 8
Dependent Claim
14 words
A hand exerciser according to claim 6 wherein said spring is a compression spring.
Claim 9
Dependent Claim
40 words
A hand exerciser in accordance with claim 1 wherein said finger grip is provided with means for accommodating the differing sizes of the fingers of a person's hand so that said fingers will fit around and grip said finger grip.
Claim 10
Dependent Claim
38 words
A hand exerciser in accordance with claim 8 wherein said accommodating means comprising a bulge portion and inwardly tapered portions above and below said bulge portion to fit the differing sizes of the fingers of a person's hand.
