Abstract
A device that exercises the shoulder and forearm is disclosed. The device is fabricated with a handle attached to a square tubular shaft that telescopes in and out over a smaller square tubular shaft. The smaller tubular shaft is attached to a round shaft with a sprocket attached. A first link of a small length of linked chain is attached to a tooth of the sprocket. A second link of the linked chain is attached to a first end of a wire cable. The wire cable passes under one pulley, then up and over two other pulleys and then is removably attached to one or more weights. By adjusting the total weight of the weights, the resistance of the device is controlled. By grasping the handle and turning it clockwise or counterclockwise, a person exercises the shoulder and/or forearm.
Claims17
A shoulder and forearm exercise device comprising;
- a frame;
- at least one shaft rotatably attached to the frame;
- a handle, the handle attached to at least one shaft;
- a cable, the cable having a cable first end and a cable second end;
- at least one weight, the weight removably attached to the cable second end;
- a means for operationally coupling the cable, the shaft and the weight such that when at least one weight is attached to the cable second end, then rotation of the handle translates to rotation of at least one shaft, which translates to a linear motion of the cable first end which translates to a vertical motion the cable second end thereby translating rotation of the handle to resistance caused by the attached weights.
A shoulder and forearm exercise device comprising:
- a frame;
- a handle;
- a first rectangular tubular member having a first rectangular tubular member first end and a first rectangular tubular member second end;
- a handle, the handle attached to the first rectangular tubular member first end;
- a second rectangular tubular member having a second rectangular tubular member first end and a second rectangular tubular member second end, such that the second rectangular tubular member first end fits inside the first rectangular tubular member second end such that the second rectangular tubular member telescopes inside the first rectangular tubular member;
- a round shaft having a round shaft first end, a round shaft second end, and a longitudinal axis such that the round shaft first end is permanently attached to the second rectangular tubular member second end;
- a sprocket, the sprocket having a rotational axis, the sprocket additionally comprising a plurality of teeth, the sprocket is attached to the round shaft such that the sprocket rotational axis is centered and positioned such that it coincides with the longitudinal axis of the round shaft;
- a linked chain having a linked chain first end and a linked chain second end, the linked chain first end rotationally attached to a tooth of the sprocket;
- a wire cable having a wire cable first end and a wire cable second end, the wire cable first end attached to linked chain second end;
- a first pulley, a second pulley and a third pulley;
- at least one weight, wherein the wire cable passes under the first pulley, over the second pulley, over the third pulley, and is removably attachable to the weight, wherein the first, second and third pulleys are rotationally attached to the frame, the round shaft being rotationally attached to the frame;
- wherein when the handle is rotated in a first rotational direction, the sprocket pulls the linked chain which pulls the wire cable which lifts the weight, thereby causing a resistance on the handle, and wherein when the handle is turned in a second rotational direction, the sprocket pulls the linked chain which pulls the wire cable which lifts the weight thereby causing a resistance on the handle.
The shoulder and forearm exercise device of claim 5 wherein the support member has a vertical socket, the vertical socket being configured to accept the round shaft below the sprocket and permit the round shaft to rotate within the vertical socket.
The shoulder and forearm exercise device of claim 15 wherein the swivel bar is configured to allow the weight to be added and removed at the wire cable second end.
A method of using a shoulder and forearm exercise device comprising:
- sitting in a chair next to the shoulder and forearm device;
- adding a set amount of weight to the shoulder and forearm exercise device;
- and
- grasping and rotating a handle, wherein the rotation causes the weight to create resistance.
The method of using a shoulder and forearm exercise device of claim 17 further comprising:
- adjusting the set amount of weight mounted on the shoulder and forearm exercise device to vary the resistance.
