Abstract

An exercising device for strengthening joints of the body, particularly the ankle joint, wherein a plate engageable against the foot of the user imparts controlled resistance in all directional movements of the joint through elastic limbs having one set of corresponding ends attached to predetermined points around the periphery of the plate and the other set of corresponding ends attached to a pair of handles which are gripped by the user for varying the degree of resistance imparted by the limbs.

Claims

1. An exercising device for exercising the joints of the leg, particularly the ankle joint, which device comprises:

(a) a substantially planar-shaped plate;

(b) means for detachably securing the plate to the foot of a user;

(c) a plurality of connection means one on each side of the plate and at least one at either the toe or heel of the plate, thereby defining at least three spaced connection points around the periphery of the plate;

(d) a plurality of elongate elastic limbs, each limb including a first end and a second end;

(e) the first ends of the limbs being detachably securable to the plate at the three spaced connection points such that a substantially triangular-shaped pattern is formed;

(f) the second ends of the elastic limbs being provided with handle means for gripping by the hands of the user; and

(g) whereby stretching of the elastic limbs by the user causes the triangular-shaped plane of the plate to provide controlled resistance against all angular and directional movements of the joint.

2. The exercising device of claim 1 wherein the elastic limbs are defined by two pairs of elastic limbs, the first ends of one pair being detachably securable to the opposite sides of the plate and the first ends of the other pair being selectively detachably securable to either the toe or the heel of the plate.

3. The exercising device of claim 1 wherein the elastic limbs are each formed of tubular rubber and the handle means includes a pair of handles.

4. The exercising device of claim 1 wherein the plate corresponds substantially in size and configuration to the front half of the sole of the foot of the user, and the means for detachably securing the plate permits the plate to be selectively secured to either the front portion or rear portion of the foot.

5. The exercising device of claim 1 wherein the means for detachably securing the plate to the foot of the user includes a plurality of straps provided with attachment means at the ends thereof.

6. The exercising device of claim 5 wherein the attachment means include Velcro connectors.

7. The exercising device of claim 1 wherein the plate is formed of semi-rigid material.
