Abstract: An adjustable support structure having a telescoping assembly that is movable by a drive mechanism between a collapsed position and an extended position. The telescoping assembly may include a latching mechanism that cooperates with one or more telescopic support members to permit or restrict movement of one or more support members relative to each other, which may depend on the position of the support members as the telescoping assembly is collapsed or extended. The drive mechanism may include linkages and a catch mechanism configured to cooperate with the latching mechanism for permitting or restricting relative movement between support members, and which may enable sequential telescopic extension or retraction of the support members. The linkages may be adapted to fit within one or more of the telescopic support members, such that the linkages may support a portion of the load, and may enhance stability by restricting lateral movement within the support members.

Abstract: An adjustable platform having an upper platform surface, at least two leg assemblies supporting the upper platform surface, and a drive mechanism that is configured to extend or retract the leg assemblies between a first position, in which each leg assembly is retracted to lower the platform toward ground, and a second position, in which each leg assembly is extended to raise the platform away from the ground. The drive mechanism includes a single motor that is drivingly coupled to each of the at least two leg assemblies, in which the drive mechanism is configured to simultaneously extend or retract both of the at least two leg assemblies between the first position and second position to thereby lower or raise the upper platform surface relative to the ground.
