Patent ID: 7188843

Claim:
A multiuse platform comprising: a wheeled support assembly having a lower crossbar, a first and a second pair of scissor legs having ends; said first pair of scissor legs connected to said lower crossbar; a platform frame assembly positioned above said wheeled support assembly, said platform frame assembly having a pivoted end, said second pair of scissor legs mounted to said pivoted end, said platform frame assembly lying on top of an upper cross bar of said first and second pair of scissor legs and each of said pair of scissor legs being pivoted together intermediate their ends, so that said platform frame assembly is movable upwardly and downwardly in relation to said wheeled support assembly; a lift structure connected to said lower cross bar on said wheeled assembly and to said upper cross bar for lifting said platform frame assembly with respect to said wheeled assembly, said lift structure comprising an upper arm and a lower arm, said upper arm being pivotally connected to said upper cross bar and said lower arm being pivotally connected to said lower cross bar, said upper and lower arms being pivoted together; a lift drive structure connected to said lift structure for raising said platform frame assembly to a desired elevation, said lift drive structure being selected from a group consisting of: a screw thread jack, a telescoping support, a hydraulic cylinder, a hydraulic actuator and a screw actuator; an extensible structure different from said lift structure having a first end pivotally mounted to said rear end of said platform frame assembly and said second end pivotally mounted into at least one of said upper cross bar and said lower cross bar; a platform having first and second ends and having said first end connected to said extensible structure and said second end pivotally attached to said platform frame assembly to permit angular raising of said first end of said platform with respect to said platform frame assembly; said platform having a locking assembly, said locking assembly releasably locking said platform to said platform frame assembly; said platform frame assembly having one end connected to a support plate by a support plate channel, a support plate locking assembly releasably connecting said support plate to permit releasable locking of said support plate to said platform frame assembly; said support plate locking assembly being different from said platform frame locking assembly and being pivotally connected to a first and a second rear end of said support plate; said platform having lower crossbar brackets and said first pair of scissor legs being mounted in a detachable manner, by an attached pusher wheel, at least one pocket, and a self locking support plate channel locking structure, used to modify the configuration of the multiuse platform to perform as a stepladder and scaffold, a work bucket, a floor jack and a mechanic creeper.
