Abstract: The invention includes a conventional exercise bicycle with foot pedals, a chain drive system and a flywheel. Rotating with the flywheel is a first gear which is in mesh with a second larger gear. Located on the face of the second gear, but offset from the center of the gear, is an eccentric which supports reciprocating arms. Movement of the reciprocating arms by the exerciser causes rotation of the second and first gears and, consequently, the flywheel.

Rotating with the flywheel is a first gear which is in mesh with a second larger gear. Located on the face of the second gear, but offset form the center of the gear, is an eccentric which supports reciprocating arms. Movement of the reciprocating arms by the exerciser causes rotation of the second and first gears and, consequently, the flywheel. The foot pedals or the reciprocating arms may independently operate the flywheel.

Abstract: The improved latch is used for selectively securing and releasing a shelf in a storage unit. This improved latch includes a pivot leg, first and second connecting legs and a support leg. A spring or other biasing means is used between the pivot leg and a bolt of the hinge, and the latch is designed to rotate about the bolt of the hinge. The first connecting leg extends outside of the storage unit, and the second connecting leg extends through a respective side panel of the storage unit and connects the first connecting leg and the support leg. In operation, the upward moving shelf first pushes the latch out of the way and, after the shelf is moved completely upward, the latch springs back into position and the support leg holds the shelf firmly in position.
