Abstract
Abstract A forearm attached device for retention of the golfer's grip in cocked configuration until the proper release point in the downswing. A ratchet assembly is attachable to the forearm and receives a retention rod pivotally coupled at its opposite end to a retention plate affixed to the back of the golfer's hand. The ratchet assembly permits unobstructed rearward passage of the rod during cocking of the wrist and hand during the backswing and assists in holding the hand cocked until club imparted forces overcome adjustably biased ratchet components which permit rod extraction allowing the golfer's grip to "break" at the proper time. An abutment plate prevents displacement of the ratchet assembly on the arm during rod extraction.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
220 words
A device for attachment to a golfer's forearm for the purpose of conditioning arm muscles so as to properly control uncocking of the forearm hand and wrist during the club downswing, said device comprising, a ratchet assembly including an adjustably biased pawl, means attaching said assembly to the forearm, hand retention means in place on the back of said hand for movement therewith, flexible elongate retention means extending rearwardly from said hand retention means into operative engagement with said pawl of the ratchet assembly, an abutment member offset rearwardly from the hand retention means and coupled to said ratchet assembly, said abutment member contacted by said hand retention means when the forearm hand is cocked and thereafter during initial uncocking of the forearm hand to maintain the ratchet assembly in place on the forearm against forces exerted by said elongate retention means. said ratchet assembly pawl permitting rearward displacement of the elongate retention means during cocking of the forearm hand during the backswing and subsequently holding same against extraction, and said ratchet assembly additionally retaining said elongate and hand retention means in a retracted state until club imparted forces during the downswing overcome the biased pawl of the ratchet assembly resulting in release of the elongate retention means and uncocking of the hand at a desired point in the downswing.
Claim 2
Independent Claim
220 words
A device for attachment to a golfer's forearm for the purpose of conditioning arm muscles so as to properly control uncocking of the forearm hand and wrist during the club downswing, said device comprising, a ratchet assembly including an adjustably biased pawl, means attaching said assembly to the forearm, hand retention means in place on the back of said hand for movement therewith, flexible elongate retention means extending rearwardly from said hand retention means into operative engagement with said pawl of the ratchet assembly, an abutment member offset rearwardly from the hand retention means and coupled to said ratchet assembly, said abutment member contacted by said hand retention means when the forearm hand is cocked and thereafter during initial uncocking of the forearm hand to maintain the ratchet assembly in place on the forearm against forces exerted by said elongate retention means. said ratchet assembly pawl permitting rearward displacement of the elongate retention means during cocking of the forearm hand during the backswing and subsequently holding same against extraction, and said ratchet assembly additionally retaining said elongate and hand retention means in a retracted state until club imparted forces during the downswing overcome the biased pawl of the ratchet assembly resulting in release of the elongate retention means and uncocking of the hand at a desired point in the downswing.
Claim 3
Dependent Claim
45 words
The device claimed in claim 1 additionally including guide rods carried by said hand retention means in slidable engagement with said abutment member to assure abutting contact of said hand retention means with the abutment member during cocking and initial uncocking of the forearm hand.
Claim 4
Dependent Claim
27 words
The device claimed in claim 2 wherein said elongate retention means and said guide rods are flexible contributing to unhindered cocking and uncocking of the forearm hand.
Claim 5
Dependent Claim
38 words
The device claimed in claim 3 wherein said rods are coupled to said hand retention means in a manner permitting movement of each coupled end about perpendicular axes additionally contributing to unhindered cocking movement of the forearm hand.
Claim 6
Dependent Claim
34 words
The device claimed in claim 1 wherein said elongate retention means carries a rack-like fitting engageable with said pawl to hold said retention means in a retracted state when the forearm hand is cocked.
Claim 7
Dependent Claim
53 words
The device claimed in claim 5 wherein said ratchet assembly additionally includes resilient means acting in opposite direction on said pawl to position the latter permitting unobstructed passage of the elongate retention means during cocking of the hand and thereafter positioning said pawl for engaging the rack-like fitting on said elongate retention means.
Claim 8
Dependent Claim
37 words
The device claimed in claim 5 wherein said ratchet assembly additionally includes means yieldably biasing said pawl towards said rack-like fitting, said yieldable means including a spring biased keeper, a pawl mounting pin biased by said keeper.
Claim 9
Dependent Claim
39 words
The device claimed in claim 7 wherein said yieldable means additionally includes adjustment means for varying the biasing action of said spring biased follower whereby the retentive action of said pawl on the elongate retention means may be varied.
Claim 10
Dependent Claim
18 words
The device claimed in claim 8 wherein said pawl mounting pin is yieldably mounted within said ratchet assembly.
