Abstract: An exercise apparatus includes a housing, a pair of pivoting foot treadles and a pair of reciprocating bellows that support the foot treadles. A sealed air system including a conduit interconnects the bellows and is operable for reciprocating transfer of air from bellow to bellow. Each of the foot treadles is pivotably movable between upper and lower positions, and has a resting position between the upper and lower positions. The resting position of the foot treadles defines a resting position of the bellows while the upper and lower positions of the foot treadles respectively define elongated and compressed positions of the bellows. In use, the elongated and compressed positions of the bellows are each no more than 5 degrees off the center resting position thereby reducing stress on the bellows.

Abstract: The coupling includes a main body with a fixed frame and a locking pawl. A carriage and impact member are connected in spring-biased fashion to the frame. The carriage controls locking of the pawl while the impact member continually urges the pawl in a counterclockwise direction. Pressing the release button causes the carriage to separate from the pawl permitting the impact member to rotate the pawl to permit entry and exit of a LATCH loop into locking communication with the tooth of the pawl. When the button is released, the carriage maintains the pawl open until a LATCH loop is impacted into the back of the pawl to disengage it from the carriage to lock the pawl closed. The invention includes a fail safe measure to maintain locking when any of the springs fail and the ability to accommodate loads much heavier than prior art couplings.
