Abstract

Guide for elevators. In contrast to the classic steel guides (see figure below), which are expensive and difficult to handle, the guide of the invention is made of hardened aluminum and is embodied in a profile (1) of markedly "Y" configuration, with a middle branch (2) constitutive of the guide itself, from which emerge two branches (4-4'') markedly divergent, which by their free end suffer respective constraints determinants of coplanar branches (5) that define a triangular isoscelic nucleus and hollow, open to the outside by means of an opening (7) opposed to the middle branch (2) and through which the fastening is made by screwing the profile to the support thereof, and from this to the wall or fixed parameter.

Description

Guide for elevators.

Object of the invention

The present invention relates to a new guide for elevators, that is to say a profile destined to be located in vertical arrangement within the elevator shaft, to cabin slip during ascent / descent maneuvers Of the same.

The object of the invention is to obtain a guide that, complying fully with all the benefits required by current legal regulations, suppose a Remarkable cost reduction in manufacturing it, as well As a greater ease and simplicity of assembly.

Background of the invention

As is known, for cab mobility a pair of vertical and parallel guides is used as an elevator, distanced in correspondence with the width of said cabin and conveniently in solidarity with a fixed structure, such as for example the walls of the elevator shaft.

To date the mentioned guides for elevators they materialize in a steel profile, fragmented in sections of the order of 5 meters long, section in "T", so that at through its transverse branch the profile is fixed to the wall or Paramento in question.

The manufacturing process of these guides results extraordinarily slow and expensive, since it is needed first of a steel furnace production phase, a second hot rolling stage of the guide, by train lamination, and a cold rolling phase of the guide, with its corresponding rolling mills, which means a very important cost of the guide in question.

On the other hand the mentioned sections of 5 meters, commonly used in the elevator industry, suppose a weight for each guide section of the order of 35 kilograms, which it makes its manipulation and mounting.

Description of the invention

The guide proposed by the invention has been conceived and structured in order to solve the problem previously exposed in the different aspects commented, greatly reducing its manufacturing cost and also greatly facilitating its assembly.

To do this and more specifically the guide that advocates part of the use of a raw material completely other than steel, preferably hardened aluminum, although it may be another appropriate ceramic type material or polymeric

Based on this raw material the profile adopts a "Y" section, with its symmetrical branches angled coplanarly inward, defining a hollow core tending to isosceles triangle, but open through the middle of its base, specifically open in opposition to its true middle branch, in which there is the area on which the vehicle will slide from elevator and on which the safety device will act against excessive speed

These coplanar branch couplings side of the profile allow fixing the guide to the wall with possibility of positional regulation, specifically providing fixing screws in grooves or oblong holes in arrangement oblique, so that using two angles as means of fixing-bridge between the constitutive profile of the guide and wall, said profile can be perfectly regulated, of a quick and simple way to get a perfect verticality thereof, both laterally and in the direction anteroposterior

This way a guide with great mechanical resistance, high degree of elasticity, high tension permissible, defining as such the maximum voltage that can withstand material at any point, low density, low value of the buckling coefficient of the material, high value of the turning radius minimum profile, sufficient hardness so that the guide does not deteriorate in the contact area with the cabin chassis and after the performance of the parachute, low coefficient of friction of the sliding faces against a plastic or similar material, avoiding periodic greasing, usually monthly, so expensive and that is precise to do with the steel guides, all with the movements suitable inertia and resistant, easy manufacturing, easy alignment in sections of 5 meters, a drastic reduction of weight, and other advantages have already been listed here description.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as an integral part of said description, a set of drawings where with character Illustrative and not limiting, the following has been represented:

Figure 1.- Shows a detail in section of a guide for elevators made in accordance with the purpose of the present invention

Figure 2.- Shows a representation of the same guide of the previous figure, and it is observed how its fixing to the wall of the building by means of two supports with colossi

Figure 3.- Shows, finally, a view in side elevation of the detail of the previous figure.

Preferred Embodiment of the Invention

In view of the figures outlined and in special figure 1, can be seen as the guide that advocates consists of a profile (1), preferably of aluminum, which adopts a sharply "Y" section, based on a branch mean (2) that will constitute the guide itself, bifurcating said middle branch (2) into a pair of divergent branches and symmetrical (4-4 '), which finally suffer a accused bending to finish off sections or triangular branches (5-5 ') coplanarians, determinants with the branches divergent (4-4 ') of a triangular tubular core isoscell (6), communicated to the outside through an opening (7), central, whose amplitude approximates that of each of the branches (5-5 ') that frame and define it, opening (7) opposed to the middle branch (2) constituting the guide itself bliss

As seen in figures 2 and 3, the fixing the profile (1) to the wall (8) is carried out with the collaboration of a pair of angular profiles (9-9 '), so that one of these profiles (9) is fixed to the guide (1) with the collaboration of a set screw-nut (10) and complementary washers, said screw (10) passing through the groove (7) of the profile (1), fixing both angular profiles (9-9 ') by another set screw-nut (11) perpendicular to the previous one and also assisted by the corresponding washers, fixing the second angular profile (10) to the wall (8) through a third screw (12) that threads into a plug (13) previously implanted in the hole operatively practiced in the wall (8). These profiles or union brackets (9-9 ') incorporate holes torn and oblique (14), which allow wide regulation positional for them, prior to the tightening of said thyme, thus facilitating a perfect verticality of the guide (1), regardless of any irregularity that may exist in the surface of the wall or wall (8).

From the structuring above described the following advantages derive:

\ circ

Substantial weight reduction of the guide, said weight being of the order of 2.1 Kg / m, that is, for a section of 5 meters will weigh 10.5 kg, compared to the weight of the order of 35 Kg of a normal steel guide in sections, facilitating substantially mounting it.

\ circ The guide manufacturing process it will be through a simple extrusion process of a very material Ductile and in one step, while the manufacturing process of a traditional steel guide requires a very procedure complicated in which they participate:

\ sqbullet

Some blast furnaces where Get the raw material.

\ sqbullet

Laminating trains hot guide.

\ sqbullet

Laminating trains cold guide
