Retractable room support mechanism

摘要

Transportable living quarters includes a main frame supporting a main living area and a slide out room which slides between an extended and retracted position relative to the main living area. An extendable member is mounted on the main frame and is rigidly connected to the slide out room floor, so that the weight of the slide out room is transferred from the floor of the main living to the extendable member as the slide out room slides between the retracted and extended positions. In one embodiment of the invention, the floor of the slide out room is leveled with respect to the floor of the main living area when the slide out room is moved to the extended position by bending of the extendable support member in response to the weight transfer. According to the second embodiment of the invention, the weight transfer of the slide out room from the floor of the main living area to the extendable member causes the inner tubular member to deflect relative to the outer tubular member through the clearance provided between the members.
