  • Patent number: 5125878
    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.
