Object of the invention

The present invention relates to a guide lightweight for elevators, whose obvious purpose is to constitute a sliding means in upward displacements and descending from the cabin of an elevator.

The object of the invention is to obtain a guide Light and at the same time mechanically resistant, whose process of manufacturing is economical compared to conventional guides used for the same purpose.

Background of the invention

As is known, displacements in the direction ascending / descending of the elevator cars, are made on corresponding guides fixed to the wall that delimits the hollow of the elevator car, or to a support structure fixed to said wall, all in a way that normally they use two vertical guides mounted parallel to each other and distanced according to the width of the cabin.

Conventional guides are usually constituted in steel, which supposes first of all a high weight both for handling and for the implementation of the guide itself at the place of assembly.

Moreover, being constituted in steel, the guide requires for its conformation a process in which first use a smelting furnace in which melts large temperature the steel, needing a lot of energy to get the steel wash.

Subsequently the molten steel is subjected to a hot rolling process, until the guide acquires the necessary dimensions, also requiring a large amount of energy

Finally a cold rolling is carried out to provide optimal tolerances and improve parameters of guide quality.

In any case, according to the process required to obtain steel guides, results from a part of high cost, due to the required energy consumption, slow, due to the different processes that need to be carried out to obtain the guide, and more importantly, a high weight of the guide definitively, which obviously hinders the handling and assembly of it.

Specifically, patents can be cited French FR 1261666 A and FR 929867 A, as well as the Patent US 5321217 A, which describes guidelines for the Sliding elevator cars, which are complex structurally, and they are not materialized in aluminum, but they are made of steel, as previously stated, so the complexity and the high weight of the same supposes a high cost, difficult manipulation, etc., as has been said throughout this pulled apart.

Description of the invention

The guide that is recommended has been designed to solve the problem described above, since first place the guide is preferably constituted in aluminum, which is a material that can be extruded, allowing to obtain the guide without need for complex smelting furnaces or laminates of any type, being able to use simpler ovens, so the guide in issue, according to the invention will result in low cost in your manufacturing and low weight, which will allow greater ease both in handling and in transport and assembly.

Also, because in the process of manufacturing, this is done by extrusion of the material, they will have optimal environmental benefits, since there will be no energy waste as required for the guides conventional steel.

Structurally the guide is constituted from of a profile preferably of aluminum, special alloy, without discard polymeric, ceramic or similar materials, which has a cross section in "Y", whose symmetric branches they have an obtuse angle bend, determining two coplanar sections and projected abroad, these being thicker sections, as is the middle branch in approximately its initial half, since the other half, which is from the that the two symmetric branches are derived, is of equal thickness that these last.

This guide is fixed to the wall that delimits the elevator shaft, through a pair of profiles angular, partially overlapping through one of its branches, while another of the branches of one of the angular profiles is fixed by screw to the wall, while the other branch of the another profile is fixed to the guide, fixations that are made in all the cases through appropriate screws complemented with washers and nuts, and based on the passage of said screws through holes elongated to allow adjustment in position of the various profiles and therefore in the assembly of the guide itself with respect to the facing.

In accordance with the above, the Advantages provided by the light guide object of the invention are evident, and can be summarized as follows:

-

Minimum energy expenditure to obtain the profile of the guide, so fully respect the environment.

-

To the Obtain the guide by extrusion of the material used as Raw material, no hot rolling trains are required and in cold, which means high energy savings.

-

The guide is economical for the material in which it is constituted, and by the simple extrusion process to obtain the same.

-

To be very light, it is easy to handle, transport and mount.

Preferred Embodiment of the Invention

As you can see in the referred figures, the guide of the invention consists of a profile preferably aluminum and "Y" configuration, as depicted in figure 1 and that has been referenced in general with the number 1, and whose guide has a central branch formed by two sections (2, 3); the first of them much thicker than section (3), being this one that is derived in two equal symmetric branches (4) each other, whose divergence defines an angle of approximately 120º, so that each branch (4) is layered at its end, determining sections (5) projected outwards, these coplanaries being each.

The central branch formed by the sections (2, 3) is which constitutes the guiding means for the elevator car, while the symmetric and divergent branches (4) are the ones that provide rigidity to the guide, fixing the wall (6) with the interposition of a pair of profiles (7, 8), leaving the branches: of these two profiles (7, 8) overlap each other, as represented in figure 3, and fixed by bolt assembly and, nuts (9), what are through through elongated holes established in that branch of the angular profiles (7, 8) to be able to regulate a greater or lesser distance between the branches (7 ', 8') of those profiles (7, 8), since the branch (7 ') is intended to be fixed precisely on the wall (6), through a screw and nut (10), which threads in a block (11) provided for this purpose in a blind hole previously formed in the wall (6), while the branch (8 ') of the angular profile (8) is the one that is fixed, through screws and nuts (12) to the profile (1) constituting the guide proper, fixation that is done precisely on the extreme and wide sections (5) of the divergent branches (4), being those sections (5) equipped with elongated holes for the same as in in the previous cases, to be able to carry out a fixation with regulation of the guide assembly with respect to the wall (6).

As already said, the angular profiles (7, 8) are affected by torn and oblique holes (13), as represented in figure 2, allowing extensive regulation positional for such profiles (7, 8) and therefore of the guide (1) with respect to the wall (6), thus enabling or facilitating a perfect verticality of the guide itself (1) regardless of any irregularity that the surface of the wall (6).
