Abstract
A motorcycle jack stand which uses a pair of spaced-apart stanchion assemblies which are mounted on the undercarriage of a motorcycle. The stanchion assemblies are movable in unison between a stowage position and an extended position. When in the extended position, each stanchion assembly includes a movable member which is to extend in contact with the ground or street. Within each stanchion assembly is included a ratchet assembly which permits each movable member to further extend, but prevents withdrawing movement. Lateral rocking of the motorcycle causes sequential extension of the stanchion assemblies resulting in at least some portion of the weight of the motorcycle being supported by the stanchion assemblies with the motorcycle positioned vertically upright. The motorcycle jack stand can be operated either by hand or by feet. Initial forward motion of the motorcycle will cause the motorcycle jack stand to automatically retract to the completely stowed position.
