Abstract:
A mobile housing is provided with a plurality of telescopic standards mounted on a base for movably supporting the top of the mobile housing between a lowered position and a raised position relative to the base. A first pair and a second pair of slidable pistons are mounted in the base for simultaneous movement between a first position and a second position, the movement of each of the pair of pistons being substantially parallel and in opposite directions to one another. A first pair and a second pair of tubes, are provided with longitudinally extending slots and a flexible conduit extends from each of the tubes to one of the standards. Each of the tubes of the first pair and each of the tubes of the second pair are disposed in spaced parallel relationship to each other between the first and the second positions. A plurality of flexible, elongated, incompressible connector elements supported in the tubes and in the conduits are connected between the pair of pistons and respective ones of the standards for movement with the pistons in the tubes to prevent buckling and unnecessary flexing of the elements during raising and lowering of the top from the retracted position to the raised position. Drive means is coupled to each of the pair of pistons to effect simultaneous movement thereof between the first and the second positions.
