Abstract
Abstract A tendon stretching device comprising a long rigid base member which acts as a lever, and a restraining band assembly pivotally mounted near one end of the member which consists of a hasp and a buckle mounted to the sides of the base member and a flexible band that is threaded through the hasp and buckle, the length of which can be increased or decreased and which can be rotated such that the flexible band can be moved to either side of the base member, allowing the device to be used on either side.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
112 words
A device for stretching tendons in the foot to increase the angle to which a foot can be pointed in an outwardly direction away from the knee comprising a long rigid base member having an upper and lower face and a restraining assembly connected near one end of the base member, said restraining assembly adapted to cross over the top of the foot and is pivotally attached to said base member whereby the device may be used from either side of the long rigid base member with the restraining assembly positioned optimally over the top of the foot, said long rigid base member being approximately twice the length of the user's foot.
Claim 2
Independent Claim
112 words
A device for stretching tendons in the foot to increase the angle to which a foot can be pointed in an outwardly direction away from the knee comprising a long rigid base member having an upper and lower face and a restraining assembly connected near one end of the base member, said restraining assembly adapted to cross over the top of the foot and is pivotally attached to said base member whereby the device may be used from either side of the long rigid base member with the restraining assembly positioned optimally over the top of the foot, said long rigid base member being approximately twice the length of the user's foot.
Claim 3
Dependent Claim
21 words
A device as defined in claim 1, together with cushioning means disposed along at least one face of said base member.
Claim 4
Dependent Claim
53 words
A device as defined in claim 2, together with cushioning means disposed along both faces of said base member, said cushioning means being positioned from that end of the base member to which the restraining assembly is attached to a point at least midway between the ends of the long rigid base member.
Claim 5
Dependent Claim
61 words
A device as defined in claim 1 wherein the mounting points of the restraining assembly are attached to the long rigid base member in a staggered manner such that one attachment point is located closer to said one end of the long rigid base member than the other mounting point whereby the restraining band covers the foot at a natural angle.
Claim 6
Dependent Claim
40 words
A device as defined in claim 1 wherein the length of the restraining band between the two mounting points of the restraining assembly is adjustable, allowing the length of the band of the restraining assembly to be shortened or extended.
