Abstract:
1. A lift guide, with a longitudinal symmetry axis comprising: a mushroom element having bilateral symmetry; the mushroom element having a head at one longitudinal end of the mushroom element, two flanges at another end of the mushroom element, and a connecting portion extending longitudinally between and connecting the head to the flanges, two side surfaces on the head, each side surface having braking and guiding surfaces, the braking and guiding surfaces adapted for movement of braking and guiding elements along the longitudinal symmetry axis of the guide; and having a portion with a larger dimension than the side surfaces along a perpendicular axis with respect to the longitudinal symmetry axis, the side surfaces being between the portion of the head with the larger dimension and the connection portion, such that the portion of the head with the larger dimension limits movement of the braking and guiding elements along the side surfaces and the longitudinal symmetry axis.
