Abstract: Disclosed is a machine and method for bending an elongate bar of metal or other appropriate material into a general "V-shape", the vertex of the "V" being a coiled spring. The machine for making the device has a motor driven, horizontally rotating spool with a spool arm to grip and bend the bar about a generally vertical axis. In manufacturing the V-shaped device, a central portion of the bar is placed against the spool so that the spool's arm can grip the bar for winding the bar about the spool. The bar is then bent an appropriate number of times around the spool to form the coiled spring portion, and thereafter the spool rotated backward a portion of a turn to loosen the coils about the spool. The device can then be removed from the machine and finished into any number of products. An example of use for such a V-shaped device is as an exerciser, exercising being performed by bending the V-arms together against the force of the coiled vertex.

Abstract: A leg exerciser for simultaneously exercising the muscle groups of the inner thighs by a cortrolled compression and controlled decompression action of the leg exerciser. The leg exerciser includes an integral helical formed bias means positioned in the center of two diverging members, each distal end of which includes a pad attached thereto for comfortable engagement against the inside surface of the user's knees. The user repeatedly exerts a positive compression force against the pads to decrease the distance between the diverging members and then to decrease the force to provide controlled decompression returning the diverging members to their free state in relation to the helix bias means. The leg exerciser is usable by exerting knee-closing pressure on the pads to exercise the sartorius, gracilis, great adductor of the thigh, long adductor of the thigh, and semimembranosus muscles of the inner thigh.
