Device for fitting tracked stair-climbing running assemblies to rigid luggage

摘要

The invention relates to a device making it possible to provide rigid thermo-formed suitcases with slideways which can receive removable tracked running assemblies so that the luggage can run, without knocking on the edges of stairs of standard sizes. The device comprises a female part (1), the base of a suitcase or multi-purpose intermediate platform, in which four recesses (2) have been hollowed, acting a slideway, two on each side of the object. In each of them, through the use of a T-shaped component (3) is inserted a tracked running assembly comprising, in the chassis (4) the pulleys (5) guiding the tracked belt (6). The guide and safety bar (7) extended by a pull strap acts as a brake when it is returned to the horizontal by the spring (8), the component (9) coming to compress the tracked belt (6). The device according to the invention allows the use of luggage which is self-sufficing as regards removable tracked conveyance, the particular feature of which is to allow stairs to be negotiated by running on their edges.
