The present invention is fully collapsible and can be easily transported as needed by a single person, with the present invention collapsing to about half of its length. A pair of included supports which are stored on the present invention in the collapsed position are used to fully support the present invention in the extended position, even providing enough support to allow the present invention to be free standing with no fixed attachment to a ground surface.

Abstract: A device, together with a method for its use, for ensuring that a patient's limb is maintained in a steady, predetermined oriented relative to the torso of the patient during an entire exercise routine. The device is versatile and, through particularly adapted to benefit shoulder rehabilitation and strengthening therapy, may potentially also be utilized for many other types of therapy related to any limb. The device comprises a first member for supporting the extremity of the patient, a second member for engaging the torso of the patient, and a third member for connecting the first and second members. In its preferred embodiments, the third member comprises a telescoping shaft, which is adjustable to a plurality of potentially desirable lengths. The second member preferably comprises a tubular structure having an arcuate configuration, being generally “C”-shaped and having a convex side and a concave side, wherein the concave side thereof is adapted to engage the torso of the patient.

Abstract: A weight lifting machine is useful for developing muscles used in arm wrestling. The weight lifting machines comprises a carrier that rotates about an axis of rotation. Pivotable levers are connected to the carrier symmetrical about the axis of rotation. A cord hangs from each lever. The cords join into a single cord that holds a weight so as to produce equal and opposite torques on the carrier. A person exerts a force on the carrier sufficient to overcome one of the torques and thereby rotate the carrier. By pivoting the levers the cords hang at different distances from the carrier axis of rotation, thereby changing the amount of torque produced on the carrier by the weight and the amount of force the person must exert to rotate the carrier. A block on the carrier contacts the cord during carrier rotation in a manner that results in a smooth and continuous resistance by the weight on the person's arm.

Abstract: Arm wrestling apparatus employing two opposed hydraulic dampers to provide resistance. The apparatus has a base and a lever pivotally mounted to the base. Hydraulic circuitry of the dampers may be controlled to vary resistance, and is employed to operate a gauge indicating force of effort. In an alternative embodiment of the invention, two novel arm wrestling devices are employed remotely from one another. Each device is provided with a video display. Radio, telephone or other links connect the displays of the two arm wrestling devices so that observers at either location may monitor a competition between two persons, one at each location.

Abstract: An improved arm wrestling apparatus for competitively matching the physical strength of two or more players as between the players. The apparatus includes first and second arm rods for transferring the forces exerted by one or more players along to the other players. The first and second arm rods are rotatably connected to each other through first and second couplers and a connector bar to prevent the arm bars from rotating beyond a predetermined angle. A set of arm bars are fixedly connected to the ends of the first and second arm rods for accepting and exerting the forces exerted and accepted by the players. The arm wrestling machine also includes a locking assembly for halting and releasing the connector bar. The locking assembly includes a support for the locking pin, a spring for biasing the locking pin in one direction, a lever for transferring force to the locking pin, and a controller for exerting or removing forces on the lever. The arm wrestling apparatus also includes a game portion.

Abstract: A wrist wrestling and exercise apparatus having a first configuration adapted to facilitate wrist wrestling contests and a second configuration adapted to allow exercise of the forearm. When configured for wrist wrestling, the apparatus has a base, a first forearm support disposed on the base, and a second forearm support disposed on the base. A first handle is associated with the first forearm support, and a second handle is associated with the second forearm support. Each of the handles is adapted to be gripped by a hand of a person and is movable relative to one of the forearm supports. The apparatus includes means for operatively interconnecting the first and second handles so that displacement of one handle relative to the one of the forearm supports causes displacement of the other handle relative to the other forearm support.

Abstract: The force resistance device of the present invention enables the muscle groups which rotate the humerus about its axis to be safely and adequately developed. A base provides a series of rollers in a radial configuration which enables the humerus to rotate about its own axis. The device protectingly surrounds the elbow and lies adjacent the radius and ulna portions of the arm. Tension cords which may be selected based upon number and individual tension characteristics extend from an elongate portion to the base portion and about the curved portion which protects the elbow.

Abstract: A muscle exerciser including a base frame for placing on the table or the thigh, a lever pivotally connected to an axle holder on the base frame by a pivot axle, a ratchet wheel mounted around the pivot axle, an elastic member received inside the axle holder around pivot axle and having two opposite ends connected between the axle holder and the ratchet wheel, an adjusting knob for adjusting the tension of the elastic member, and a blocking means releasably meshed with the ratchet wheel permitting the elastic member to be compressed as the lever is pressed against the base frame, and a counter for counting the number of times that the lever has been continuously pressed.

Abstract: An apparatus enabling one person to do the arm-wrestling exercise comprises an animated arm, which is made of an appropriate material and is composed of a plurality of iron bars having an appropriate elasticity. The animated arm is fastened to an arm support mount by means of an elongate iron piece and a screw. The arm support mount is fastened by means of a plurality of small quick screws to a triangular seat which is in turn fastened to a desk top by means of a plurality of large quick screws.

Abstract: A new and improved arm wrestling apparatus includes a table assembly and a simulated arm assembly supported by the table assembly. The simulated arm assembly includes a plurality of receiver assemblies for receiving respective incremental counterforce resistance elements. The receiver assemblies are arrayed longitudinally beside and symmetrically astride a longitudinal axis. An arm motion limit assembly is supported by the table assembly for limiting motion of the simulated arm assembly. A limit signaling assembly is supported by the table assembly for signaling when the simulated arm assembly reaches a limit of arm motion. The limit signaling assembly includes a force-receiving portion adapted to receive force exerted by an incremental counterforce resistance element when the simulated arm assembly reaches the arm motion limit assembly.

Abstract: An arm wrestling simulating device having a frame attachable to a solid flat surface, mounting a rotatable upstanding arm-simulating lever which may be rotated both clockwise and counterclockwise against the resistance of springs contained within the frame, so that both left and right arms of the user may be selectively employed.
