Abstract
Abstract An arm exercise device that is compact and portable for strengthening either arm through arm wrestling exercises. There is a base member supporting bearing mechanism of a shaft member. A handle is transversely disposed on the shaft and is movable through an angle of about 180°. The free end of the handle is provided with a hand-grip that is pivotally connected thereto, and the hand-grip is also reversible to either side of the handle. An adjustable frictional brake mechanism is furnished with the shaft to resist the turning force exerted on the handle by the arm.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
159 words
An arm exercise device, comprising: (a) a base; (b) a bearing mechanism mounted on said base and journalling a shaft for pivotal movement with respect to said base; (c) a generally transverse handle joined to said shaft and movable therewith; (d) a hand-grip joined to the handle near the top portion thereof; and (e) an adjustable brake mechanism for resisting said pivotal movement of said shaft, (f) said brake mechanism including a fixed brake member and a movable brake member with said fixed brake member being releasably engaged by said movable brake member, (g) said fixed brake member being mounted on said base and said movable brake member being interconnected to said shaft for movement therewith, said movable brake member being movable through an arc and substantially within the plane described by the shape of said fixed member and (h) said fixed brake member comprising an arcuate member, and said movable brake member comprising remotely controlled friction brake shoes.
Claim 2
Dependent Claim
159 words
An arm exercise device, comprising: (a) a base; (b) a bearing mechanism mounted on said base and journalling a shaft for pivotal movement with respect to said base; (c) a generally transverse handle joined to said shaft and movable therewith; (d) a hand-grip joined to the handle near the top portion thereof; and (e) an adjustable brake mechanism for resisting said pivotal movement of said shaft, (f) said brake mechanism including a fixed brake member and a movable brake member with said fixed brake member being releasably engaged by said movable brake member, (g) said fixed brake member being mounted on said base and said movable brake member being interconnected to said shaft for movement therewith, said movable brake member being movable through an arc and substantially within the plane described by the shape of said fixed member and (h) said fixed brake member comprising an arcuate member, and said movable brake member comprising remotely controlled friction brake shoes.
Claim 3
Dependent Claim
25 words
The invention of claim 1, wherein the said arcuate member has brake surfaces which are substantially equidistant from the longitudinal axis of the said shaft.
Claim 4
Dependent Claim
32 words
