Abstract

Abstract The described apparatus is adapted to strap to the arm of a bowler or golfer to restrict the "breaking" of the player's elbow on making the bowling delivery or in completing the golf stroke so as to enable repetitive deliveries and/or strokes to be duplicative of one another for improved consistency of performance. The apparatus includes a pair of straps which encircle the user's arm above and below the elbow. The arm encircling straps are joined to each other by two pivotally connected sections, and the force required to move one section relative the other may be varied by a setscrew which passes through one section and bears against a land on the other section. Spaced apart pivot apertures in the pivotally connected sections enable such sections to be disassembled and then reassembled to each other at different pivot positions, to provide a size adjustment.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 346 words
An elbow movement restricter for use by a bowler comprising: first strap means adapted to encirle the upper arm of the bowler above the elbow, to be held in place thereat; second strap means adapted to encircle the forearm of said bowler below the elbow, to be held in place thereat; and means adapted to be positioned adjacent said elbow, interconnecting said first and second strap means, controllable to vary the tension thereof in restricting the movement of said first strap means relative to said second strap means during movement of the arm of said bowler to which said restricter is affixed; wherein said interconnecting means is adapted to be positioned adjacent the elbow only on the inside position of the right arm of a right handed bowler, and adjacent the elbow only on the inside portion of the left arm of a left handed bowler; wherein said interconnecting means incorporates a pair of extending arms coupled to respective ones of said first and second strap means and rotatable one about the other, and further incorporates means for continuously varying the tension between said pair of extending arms to controllably vary the relative movement between said strap means in maintaining substantially straight the elbow of the delivery arm of a bowler during the bowling motion; wherein the one of said pair of extending arms which is coupled to said first strap means includes a semicircular land situate adjacent the crook of the bowler's elbow; wherein the other of said pair of extending arms which is coupled to said second strap means is secured to said semicircular land by a pivot means so as to form a hinge therebetween; and wherein said tension varying means comprises screw means extending in a direction through said other of said pair of extending arms towards the land of said one of said pair of extending arms, and rotatable in clockwise and counterclockwise directions to controllably vary the relative movement between said pair of extending arms and between said first and second strap means to which said extending arms are coupled.
Claim 2
Dependent Claim 346 words
An elbow movement restricter for use by a bowler comprising: first strap means adapted to encirle the upper arm of the bowler above the elbow, to be held in place thereat; second strap means adapted to encircle the forearm of said bowler below the elbow, to be held in place thereat; and means adapted to be positioned adjacent said elbow, interconnecting said first and second strap means, controllable to vary the tension thereof in restricting the movement of said first strap means relative to said second strap means during movement of the arm of said bowler to which said restricter is affixed; wherein said interconnecting means is adapted to be positioned adjacent the elbow only on the inside position of the right arm of a right handed bowler, and adjacent the elbow only on the inside portion of the left arm of a left handed bowler; wherein said interconnecting means incorporates a pair of extending arms coupled to respective ones of said first and second strap means and rotatable one about the other, and further incorporates means for continuously varying the tension between said pair of extending arms to controllably vary the relative movement between said strap means in maintaining substantially straight the elbow of the delivery arm of a bowler during the bowling motion; wherein the one of said pair of extending arms which is coupled to said first strap means includes a semicircular land situate adjacent the crook of the bowler's elbow; wherein the other of said pair of extending arms which is coupled to said second strap means is secured to said semicircular land by a pivot means so as to form a hinge therebetween; and wherein said tension varying means comprises screw means extending in a direction through said other of said pair of extending arms towards the land of said one of said pair of extending arms, and rotatable in clockwise and counterclockwise directions to controllably vary the relative movement between said pair of extending arms and between said first and second strap means to which said extending arms are coupled.
