Abstract: A digit grip sensor for measuring the grip strength of the human hand. The digit grip sensor comprises a post support having a first and a second sensor therein. A first post extends through the first sensor and a second post extends through the second sensor. A crossbar spaced from the post support extends between the first post and the second post. Each sensor has a plurality of strain gages mounted thereon for measuring the deflection of the sensor. The crossbar can have a plurality of individual digit sensors mounted thereon for measuring the contributions of each finger to the grip force. The crossbar and the individual digit sensors can be adjusted for various hand and finger sizes.

Abstract: A hand exerciser of a type having two hand grips squeezed together form an open position against the resistance of a spring and then released to again assume their open position which is achieved using a movement-limiting link, in which the link is limited in descending movement along length positions of the spring which unavoidably occur when the hand grips are together to a position which obviates "catching" on the spring that would impede opening movement. The link is held in a position where the spring connecting structure is angular rather than straight, which is less vulnerable to "catching".

Abstract: An exercise apparatus for strengthening the muscles of the upper body and arms includes a handle means, a connecting means, and a bias means or counterweight system. The connecting means is telescopically positioned within the handle means. The bias means, or counterweight system, provides the resistive force desired during a work-out period.

Abstract: A jump rope is provided to facilitate easier use by people with visual or neurological impairments. The jump rope includes at least one handle having the rope rotatably mounted therein. The handle further includes at least one detector for identifying the rotational orientation of the jump rope relative to the handle. The detector can move outwardly and into contact with the hand of the person using the jump rope so that the person achieves non-visual indication of the position of the rope relative to the handle.

Abstract: A spring is made of a flexible plastic material in generally arcuate shape. This spring of adjustable strength is especially suitable for use in a hand exercising device, which may have optional inserts which, in turn, serve to increase or reduce the strength the grip required; and an optional counting mechanism to indicate desired features of exercise with the grip such as repetitions or time.

Abstract: An elongate body extending between opposite ends for wrapping around hand of a person in which one of the opposite ends is resiliently releasably clamped to a wrist of a person. The glove also secures the two opposite ends together at the wrist of a person.

Abstract: An exercise apparatus for providing improved muscle conditioning via push-ups or similar exercises. The apparatus comprises an elongated body with end supports and two rotatably affixed hand grips. The elongated body has a plurality of pairs of bushing lined holes. Each hole of each pair is equally spaced from the elongated body's vertical centerline. The hand grips are rectangularly shaped having a pin extension that slidably and rotatably fits in the body's bushing lined holes. The top horizontal portion of the rectangle is an ergonomically shaped handle. The pin and, consequently, the hand grip are locked into place in the body via a spring clip which engages the pin at its free end. The spring clip engages the underside of the body such that the hand grips cannot be withdrawn from the body until the clip is removed. While being used, the user grabs the ergonomically contoured handles and performs a push-up or similar exercise.

Abstract: The invention is a semi-resilient exercise grip that has a non-resilient particulate core surrounded by a resilient rubber covering. Within the core there is also a dry lubricant such as talc that allows the particles to move over each other without damage. The outer covering may consist of a single thick latex layer, a thin latex layer surrounded by a thick rubber layer or a number of thin latex layers. The semi-resiliency of the grip enables a user to deform the grip and thereby change its shape. The grip can be moved within the hand to allow the user to deform it repeatedly while changing the grip's shape each time.

Abstract: A resistance spring-type exerciser for optionally exercising individual fingers, or an entire hand, in which, for individual finger exercises, individual finger-gripped members are closed in a first direction against the resistance of a first set of springs, and, for exercising an entire hand, a second set of springs is operationally added to the first set by requiring closing movement thereagainst from a second direction opposite to the already noted first direction closing movement.

Abstract: A novel, hand-held, sphere-shaped, palm-compressible, upper-body exerciser is provided with a mechanical switch, placed within a cavity internal to the sphere.

Abstract: Disclosed is a method and apparatus for therapeutic exercise of the muscles and tendons of the group that give strength and movement to the hands and fingers. The apparatus comprises a body of pliable elastic material having finger holes formed therein so as to have an interference fit with fingers inserted into the body. The finger holes are dimensioned so that the periphery of the holes will cover substantially the entire length of the fingers, if not parts of the backhand and palm. Portions of the holes are located so as to come into contact with the distal end of the fingers when the fingers are moved or curled during movement. The method comprises the steps of inserting the fingers into the holes and moving the fingers and hands against the elasticity of the body of material. The movements may be by the fingers themselves or the opposing movements of both hands.

Abstract: A hand exercising apparatus for strengthening the hand and forearm muscles and improving joint mobility while protecting the skin of a hand using the apparatus is disclosed. The apparatus includes an outer frame having an outer crossbar and an outer grip bar transversely mounted between two parallel rods. An inner frame is slidably mounted in the outer frame and has an inner crossbar and an inner grip bar parallel and adjacent to the outer crossbar and the outer grip bar. A coupling assembly connects the outer crossbar to the inner crossbar and provides a resisting force as the inner frame is moved along the outer frame. An altering device increases and decreases the distance over which the inner frame may be moved along the outer frame. An inner cushion sleeve is mounted on the inner grip bar, while an outer cushion sleeve having an area of reduced thickness for receiving the second crossbar is mounted on the outer grip bar.
