摘要

One-way automatic brake for telescopic columns, designed to support electrical appliances, characterized by comprising one or more surrounding regattas practiced inside the areas of the fixed external element of the system against which it adjusts the internal element displaceable in axial direction, whose races they essentially have a frustoconical zone, with conicity directed downwards, housing inside each one of them an elastic ring of elastic material, calculated in such a way that it can be lodged with slack in the upper part of the corresponding regatta, but that when it is displaced downward by the pulling action exerted by the mobile part of the column moving axially downward, is wedged between this part and the lower frustoconical region of the race, exerting a braking action on it.
