The object of the invention is a new lift guide.
An unresolved problem present in current (known) lift guides is that of safety, particularly with regard to preventing the guides from coming out of the cabin and the counterweight and maintaining the overspeed brakes, when they operate, inside the guides.
This problem is accentuated, for example, in seismic zones, which are very critical with regard to the derailing of the lift and especially to of the counterweight which, due to the accelerations caused when earthquakes occur, come off the guides and strike against the cabin.
The new lift guide, according to the invention, limits movements in two directions, while the current (known) guides only limit it in one direction. For this purpose, the lift guide, according to the invention, being of the type made with a symmetry axis
The following is included in the new lift guide that is the object of the invention:
Other additional advantages of the lift guides according to the invention are deduced from the description and figures represented in the attached diagrams in which:
a to 3e schematically represent general cross-sections of lift guides according to the invention similar to
An example of practical, non-limiting embodiment of this invention is described as follows:
The lift guide, according to the invention, is of the type made up of a symmetry axis
According to the invention—see FIG. 2—, the mushroom element (1) consists of a head (3) that prevents the movement of the braking and/or guiding elements (fg) along the
Based on this basic concept, any practical alternative embodiments of guides that do not essentially alter, change or modify the proposal are interchangeable and are included in the object of the invention.
According to the embodiment represented in
According to the embodiment represented in
According to the embodiments represented in
In the embodiments represented, the side braking and guiding surfaces (3′), (3″) for the braking and guiding elements (fg) of the lift, irrespectively of whether they are defined in the mushroom element (1) or in the head (3) are straight. In the lift guide, according to the invention, it is also indicated that said side surfaces will be curved (concave—as in
