Abstract

A device for exercising the limbs of an individual. The inventive device includes a mounting assembly for securing to the frame of a door. A rotatable arm is coupled to the mounting assembly and is frictionally retarded against rotation thereof relative to the mounting assembly. A limb engaging assembly is mounted to a distal end of the arm, whereby an individual can rotate the arm to exercise the engaging limb.

Claims

1. A door frame mounted exerciser comprising:

a mounting means for securing to a frame;

a rotatable arm rotatably mounted at a proximal end thereof to the mounting means;

and,

a limb engaging means coupled to a distal end of the rotatable arm for being engaged and manipulated by an individual to effect rotation of the rotatable arm to exercise an engaged limb;

wherein the mounting means comprises a mounting block having a receiving bore and a first clamp leg projecting therefrom;

a threaded rod projecting from the mounting block;

a second clamp leg slidably positioned about the threaded rod;

a securing nut threadably engaged to the threaded rod so as to capture the second clamp leg between the securing nut and the mounting block;

a support axle coupled to the rotatable arm and having a guide projection extending from a first end thereof positioned within a receiving bore directed into the first clamp leg;

a fixed clamp member fixedly secured to the mounting block;

a removable clamp member coupled to the fixed clamp member by a pair of frictional fasteners directed through the removable clamp member and threadably engaged to the fixed clamp member, the removable clamp member and the fixed clamp member each having semi-circular bores extending therethrough which cooperate to define a bore through which the axle projects, whereby the frictional fasteners can be rotatably advanced relative to the fixed clamp member so as to clamp the support axle within the bore extending between the clamp members.

2. The door frame mounted exerciser of claim 1, wherein the rotatable arm is shaped so as to define an elongated slot;

and further comprising a securing fastener directed through the elongated slot and threadably engaged to a second end of the support axle.

3. The door frame mounted exerciser of claim 2, wherein the limb engaging means comprises a substantially cylindrical handle tube rotatably mounted to the distal end of the rotatable arm.

4. The door frame mounted exerciser of claim 3, wherein the limb engaging means further comprises a foot plate secured to the handle tube.

5. The door frame mounted exerciser of claim 4, wherein the limb engaging means further comprises a lateral guide plate projecting from the foot plate and substantially parallel to the rotatable arm;

and a securing strap slidably coupled to the lateral guide plate for securing about a limb of an individual.

6. The door frame mounted exerciser of claim 5, wherein the first clamp leg of the mounting means terminates in an engaging projection so as to define a door frame receiving cavity between the engaging projection and the mounting block.
