Description

High strength sliding flange, for guides of elevator.

The present invention fits within the industrial sector of elevators and, more specifically, in the scope referring to the guides or "raceways" of the elevators, which require higher quality indices every day for the speed increase of the elevators and by the demands of user comfort.

In the current state of the art already known extremely accurate lift guides (with very high degree of perfection in its finishes) and also highly joining systems precise for the aligned coupling of guides which theoretically, it makes unlimited the "paths of rolling ". These guides are fixed to the building using flanges of tie up

Issues raised and unresolved of these "raceways" arise precisely in these flanges of mooring, for external conditioning among which it is possible to emphasize the settlements of the building and the performance of the parachute, what which makes the tie ties come to withstand large efforts, with risk of deformation of the "roads of rolling. "

In the current state of the art it is not known no lift guide tie down system based on flanges of fit on guide wings that do not apply forces on the own guide and / or that does not require some mechanization in origin on The wings of the guide.

The flange object of the invention solves this Problem: fits on the wings of the elevator guide and not apply forces on it. It is characterized because, understanding each guide a soul-fungus and a wing on each side, each flange consists of at least two jaws; a base plate; means for guided connection between jaws and base plate and means for adjusting the jaws on the wings without applying forces on the guide.

In particular, the said means for adjusting the jaws on the wings without applying forces on the guide the constitute sets of threaded studs that tap into holes jaw threads and each have a threaded nut in the extreme area that emerges from the corresponding jaw, so that the adjustment takes place with:

a) a first tightening, after interposition of a gag between jaw and wing, of the stud in the hole of the gag to allow the removal of said gauge;

b) a second tightening of the nut on the stud to fix it with respect to the jaw, and

c) a definitive tightening of the mentioned means of guided union between jaw and base plate.

In the flange object of the invention the forces of friction are very low, the raceway is completely isolated of the wall and the non-variation of the raceway is guaranteed over time, for all of which it is especially Recommended for high loads and medium buildings.

To better understand the purpose of this invention, a preferred form of practical realization, susceptible to accessory changes that do not distort its foundation.

Figure 2 represents a general view in High strength sliding flange perspective, for guides of elevator object of the invention, for a non-limiting example of realization.

Figure 3a represents, in section and detail enlarged, a jaw (2nd).

Figure 3b represents a plan view, corresponding to figure 3a, in which said section.

Figure 4 represents a similar general view. to figure 1, for an alternative embodiment of the means of union (2).

An example of practical, non-limiting embodiment of the present invention.

High strength sliding flange, for elevator guides object of the invention consists of at least paths jaws (2nd); a base plate (2b), media (2) for guided connection between jaws (2a) and base plate (2b); and means (3) for adjusting the jaws (2a) on the wings (14) without applying forces on the guide (1). Each guide (1) is from those that comprise a soul-fungus (13) and a wing (14) on each side - see figure 1-.

According to the embodiment shown, the jaws (2a) are arranged in pairs as opposed and behave each a:

a) a front pocket recess (21) of geometry conjugated with that of the corresponding surface lateral wings (14) of the guide (1) they face;

b) a threaded rod (22) that emerges from its base; Y

c) at least one threaded through hole (30).

Means (2) for guided union relate each other to said jaws (2a) and the base plate (2b) and, at the same time, keep them against those lateral surfaces of the wings (14), housing them in their front pocket recess (21).

Specifically, and for the embodiment represented there are two jaws (2a), one on each side of the guide (1), mounted on the base plate (2b) using the said guided joining means (2), but several can be arranged jaws (2a), in pairs or to the tresbolillo, without altering the essence of the invention.

For the embodiment represented, those cited Guided joining means (2) are, in addition to the aforementioned stems threads (22) emerging from the jaw bases (2a), about torn holes formed on the base plate (2b); and some nuts (23) which, threaded in the corresponding stems (22), previously housed in the corresponding torn holes, compress them together with interposition, in their case, of tightening washers (24) - see figures 1 and 4-.

The means (3) for adjusting the jaws (2a) on the wings (14) of the guides (1) without applying forces on said guides (1) are, in addition to the aforementioned through holes threaded (30), threaded studs (31) at the rate of one per each through hole (30) in which it threads and nuts (32), to ratio of one for each stud (31) in which it threads.

They are included in the object of the invention any ways, ways or embodiments to bring it to the practice that does not alter, change or modify essentiality proposal of both the media (2) and the media (3) and, in particular:

a) that the aforementioned pocket-recesses (21) of the jaws (2a) and lateral surfaces of said wings (14) of the guides (1) present totally or partially conjugated geometries;

b) that the said guided joining means (2) they constitute, for example, threaded hole sets formed in the bases of the jaws (2a) in which house threaded screws (2 ') that compress the base plate (2b) against its head and its own clamp (2a) with interposition, in case of tightening washers (24) -see figure 4-;

c) that each flange (2) includes more than two jaws (2a), arranged in pairs or three-way in both sides of the guide (1).

With this structure, layout and particularities, to mount the jaws (2a) holding the guide (1) without applying forces on it, successively:

a) fit the jaw (2a) semi-fixed to the base plate (2b) with the rod (22) and nut (23) so that its front pocket recess (21) encompasses the wing (14) of the guide (1) and a superimposed gauge, sandwiched between them.

In case there is more than one set of rod (22) / nut (23) will proceed analogously with all of them;

b) tighten the stud (31) by threading it on the hole (30) of the jaw until, resting its end on the base plate (2b), allow to extract the aforementioned gauge interspersed

In case there is more than one stud (31) for each flange (2a) it will proceed in a similar way with all they;

c) tighten the nut (32) on the stud (31) until fixed with respect to the jaw (2a).

In case there is more than one stud (31) for each flange (2a), the same shall be done with all nuts (32);

d) definitely fix the jaw (2a) to the base plate (2b) re-tightening the rod set (22) / nut (23) - or all rod sets (22) / nut (23) existing, if more than one exists.
