A snow cycle includes a conventional motorcycle chassis having a set of steerable front forks and a rear swing arm, which normally mount front and rear wheels of the cycle, respectively. A snow track module is mounted to the rear swing arm and has an endless track driven by a cog connected to a drive sprocket of the engine by a single chain. At least one and preferably a pair of skis are mounted off the front forks and are pivotable fore and aft as well as tiltable to either side to maintain the...

An improved bicycle ergometer system is disclosed which reduces the limitation on the work input necessary to operate the device and, at the same time, accomplishes an increase in the relative amount of isotonic exercise provided by operation of the system. The system provides real-time auxiliary energy input control based on the instantaneous difference between the actual operator work rate and the intended work rate. The preferred embodiment includes a stationary bicycle frame having a pedal a...

A cycle exerciser having a vaned wheel rotatably mounted on a frame and arranged to absorb energy by movement of the broad surfaces of the vanes against the surrounding body of air. Rotation of the wheel is effected through a pair of foot pedals and connected chain and sprocket mechanism, and/or through a pair of handle bars. Each handle bar is pivotally connected to the frame and is also connected to a respective eccentric through a crank ring rotatably mounted on that eccentric and a drive bar...

A cycle rack for carrying longitudinally extending objects including a pair of V-shaped branches connected to each other at an acute angle in a lower portion of the pair of V-shaped branches, a connecting link apparatus mutually pivotable between the pair of V-shaped branches and a gripping and holding apparatus to grip around and hold the rack on a towing hitch ball. A toggle joint apparatus between the pair of V-shaped branches holds and grips the hitch ball through the gripping and holding ap...

A snow cycle including a frame, a ski assembly mounted on the front of the frame and a handle operatively connected to the ski assembly, a wheel mounted for rotary motion on the back of the frame, a number of drive blocks mounted around the perimeter of the wheel, an idler roller assembly mounted on the frame in a spaced relation to the wheel, a drive belt wrapped around the drive wheel and the idler roller assembly, the belt having a plurality of drive plugs mounted in a spaced relation to enga...

The composition of a refrigerant in a refrigeration cycle is detected, so that the refrigeration cycle is controlled by a control method in accordance with the detected composition. A control target value is set in accordance with the detected composition, and when the composition is varied, the control target is changed in accordance with that variation. As a result, even when the refrigerant composition is varied, the refrigeration cycle can be operated stably. The refrigeration cycle uses a n...

An exercise cycle having front and rear wheels rotatably mounted on a rigid frame. Propulsion for the cycle is provided by a driving column which is mounted on the frame for forced oscillatory movement in the plane thereof by a rider. The oscillatory movement is converted to rotational motion by a one-way clutch which is connected to drive the rear wheel. A handle bar is rotatably mounted on the driving column and is coupled to the front wheel by a steering mechanism that functions independently...

Disclosed is a novel cycle reflector and a cycle-caliper brake subassembly containing this novel reflector. The reflector is specially adapted for installation on a cycle having caliper braking means and comprises a first generally flat surface adapted to abut transversely against a cycle fork assembly, at least one pair of lateral support members to cooperate with the fork assembly, a second generally flat surface adapted to be in alignment substantially vertical and substantially normal to the...

A motorcycle seat for carrying a rider and a rear passenger with the rear passenger having a permanent rear back rest and the front rider having a pivotal back rest. The pivotal back rest pivots upwardly from the rear seat by raising a cushioned portion of the rear seat from a downward position to an upright position.

An exercising device for bed patients is provided with straps for attachment to the mattress of a bed and has a hand holding device and foot operated energy absorbing mechanism for use by the patient in an effort to retain and/or restore muscles unused or weakened by an illness. Separate adjusting means are provided for positioning the hand holding device at a proper level and for varying the resistance on the foot operated energy absorbing mechanism to simulate different exercise levels. Dispos...
