  • Patent number: 4705269
    Abstract: An exercise apparatus including upper and lower body exercising assemblies which are operable in isolation or in conjunction with each other. The upper body assembly includes rotary handle members which rotate a driving sprocket. The upper driving sprocket in turn rotates an upper driven sprocket which is connected via two additional sprockets and an endless chain to the wheel of the lower body exercising assembly. The lower body assembly is a conventional exercise bicycle including rotary foot pedals for rotating a lower driving sprocket which in turn rotates a lower driven sprocket connected to the wheel. The upper and lower driven sprockets are one-directional ratcheted sprockets which can be rotated only by the endless chain joining them to the upper and lower driving sprockets, respectively, to provide the independent operation of the upper and lower body exercising assemblies.

  • Patent number: 4703400
    Abstract: A vehicular lamp having a one piece open topped resilient housing containing an outer peripheral groove that permits the housing to be snapped into a receiving opening formed in a body panel of a vehicle. The housing further includes an inner peripheral groove located above the outer groove into which a lens is snap fitted to close the housing. The inner groove is offset from the outer groove a sufficient distance so that the lens can be removed and replaced without having to remove the housing from the body panel. An outwardly disposed lip protrudes from the top of the outer groove that is inclined downwardly over the groove opening so that it will form a biased seal against the rim of the panel opening when the lamp is snap-locked in place.
