Abstract: A bicycle which comprises a frame carrying at its rear end a wheel actuated by a pedal mechanism while the front end carries a collar. A brace is pivoted to the frame in the region of the pedal mechanism and so is a saddle post. The front end of the brace also carries a collar, both collars are slideable along an upright stem carrying the handle bars at the upper end and the front wheel of the bicycle at its lower end. A latch releasably holds the frame collar on the lower end of the stem while a cable attached at both ends to the handle bar and to the brace collar and also attached to the brace collar serves to maintain the latter in an intermediate position along the stem, whereby the brace, the front portion of the frame and the lower part of the stem forms a triangle holding the bicycle in erected position. A releasable stay rod pivotally connected to the saddle post and releasably latched to the rear portion of the frame, maintains the saddle in erected position.

Upper end portions of the legs are pivotally mounted to the frame, the stand being normally spring biased on the pivot mounting in the upwardly non-functional position. A side arm on the stand extends outwardly of the motorcycle in the non-functional position and is adapted to move the stand downwardly against the force of the spring to a rearwardly-vertical position and then past the pivot center to a forwardly-vertical position against the weight of the motorcycle to raise the motorcycle to a steady at rest position with the lower ends of the stand legs on the ground surface under the motorcycle.

Abstract: A motorized snow vehicle stand, for supporting the rear of the vehicle in a raised parking position so that the endless drive track is elevated above the ground, including a bail carried on a transverse horizontal pivot bar extended across the rear of the vehicle and rotatable through an arc of more than 180.degree. from a raised or upright inoperate position where it is normally held against the rear of the vehicle by a manually releasable hook to a fully operative vehicle supporting position in engagement with the ground under the raised rear end of the vehicle where it is disposed in inclined position forward of dead center. The pivot bar is mounted on the vehicle in releasable nonrotatable relation and a spring is biased between the pivot bar and the bail, with provision for releasing and turning the bar to vary the spring tension. On release of the holding hook, the bail swings in two stages under action of the spring, namely through a first arc of less than 180.degree.
