Description

Guide for fast doors.

Technical field

The present invention relates to a guide for guiding a vertical sliding closing curtain in fast doors also known as maintenance, equipped with means for the reinsertion of the closing curtain therein an accidental exit of these.

Background of the invention

Fast doors are devices normally of vertical opening, used in areas of passage of facilities manufacturing or industrial through which there is circulation frequent vehicles and pedestrians, whose opening maneuver and closing is done at high speed, so that the stay that is leave or that is accessed be open the shortest time possible.

This type of door is usually opening automatic, for which it has sensors that detect the proximity of a vehicle or pedestrian, activating the opening of the same; its closure is usually done by timing, providing enough time for the passage.

A fast door is constituted by a curtain, crossed in some cases, by a set of crossbars flexible horizontals, separated from each other at vertical distances regular, whose purpose is to give consistency to the curtain, which it moves vertically between two facing side guides. To do this, the ends of the crossbars run housed in the Inside the vertical guides. In other cases, it is dispensed with the crossbars, placing retention stops on the sides of the curtain, which will circulate inside the guides. In this Type of doors this model refers to.

Given the exhaustive use made of this type of doors, it is common that these are knocked by vehicles during their entry or exit maneuver, and therefore they are equipped with means that minimize the damage of these accidents by aim to minimize repair times.

In this sense, the most common characteristic of this type of doors, is the fact that the curtain can leave the guides in case of being hit, before the curtain breaks or permanent deformation of the crossbars. To do this, these crossbars have a high degree of flexibility or their ends they have a configuration for retraction in case of impact.

In any of these cases, the following problem to solve is the reinsertion of the crossbars in the guides Normally, the solution used is the incorporation of a funnel in the highest part of the guide capable of reinserting the ends of the crossbars in the guides when the curtain comes down. So, after derailing the curtain, it has to Operate in opening to be folded or rolled up completely in its axis (depending on whether it is a rolling or folding door), of so that the misplaced crossbars slide on the outside of the guide and then operated in closing, so that The ends of the dislocated crossbars return to the guides Through the funnel. An example of this type of door is the one described in the patent ES 1 057 808 U,

However, this system, by requiring the drive up and down the door, presents the inconvenient that the repair maneuver results relatively long On the other hand, the rise of the curtain is it is forced through the door motor, but the down is done by gravity, there is the possibility that this is locked if the reinsertion of the crossbars in the guides It is not done correctly.

As an alternative to these devices, they have developed doors that incorporate means for reintegration into the curtain guides both in the ascent maneuver, as in the of descent, which guarantees a faster execution. Without however these devices have been developed as couplings or insertable inserts on the guides, so that the door manufacturing and assembly is more complicated and expensive, reaching extremes where parallel to the guide is necessary place an antifriction element along the entire guide and on that anti-friction element or as a differential part of that, is incorporates the curtain reinsertion device. An example of that type of doors is the one described in the patent ES 2 128 886.

Description of the invention

Generally speaking, the present invention will be refers to a guide for the construction of fast doors which incorporates means for curtain reinsertion without crossbars in the maneuver of ascent of this and a zone of fixation of the motor mounts and curtain shaft, shaped as a single operating part, without any attached or complementary parts liable to be mounted on it for use, resulting in a cheaper element to manufacture and much simpler to install.

Specifically, the new guide is made up of a profile or two symmetric profiles joined by welding, which they constitute a rectangular monobloc body operative in position vertical, open all along one of its faces by means of a narrow longitudinal groove preferably centered on the face, that groove being flanked by a mouth facing the outside of the guide, made by beading or bending the own profile At the same time, the new guide incorporates at its end superior a flared area constituting the means for the reinsertion of the discolored curtain, under which, the groove is widens to form an preferably area opening triangular by which the ends of the curtain are introduced in The Guide.

The section of the guide between the area flared and its upper end is sectioned longitudinally and constitutes a seating area on which fix the motor supports and curtain shaft.

The rear face of the monobloc body rectangular, opposite to the one that incorporates the groove, it has a configuration where a deformation zone is defined through of which, the guide can make an opening movement, which in cooperation with the mouth of the groove they facilitate the exit Curtain controlled. This deformation zone is shaped preferably by a narrow protruding strip of the face, which at the same time constitutes the ideal zone for the realization of the welding line or points in cases where the guide is consolidated by two symmetrical profiles welded together.

Description of the drawings

In order to illustrate how much so far we have exposed, is accompanied by the present specification of a sheet of drawings in which only Sample title

Example Description

The novel guide for fast doors, according to the illustrative example, it is made up of two symmetric profiles (1 and 2) joined by a welding line (3), which constitute a rectangular monobloc body (4) operating in an upright position, open all along its front face through a slot longitudinal (5) flanked by a mouth (6) facing the outside of the guide, made by bending their own profiles (1 and 2).

At the same time, the new guide incorporates at its end superior a flared zone (7) constituting the means for the re-insertion of the curtain (not shown), under which the groove widens to form an opening of triangular area (8) by which are introduced the ends of the curtain in the guide.

The section of the guide between the area flared and its upper end is sectioned longitudinally and constitutes a seating area (9) on which motor mounts and curtain shaft are fixed (no illustrated).

The rear face of the rectangular monobloc body has a deformation zone (10) as a narrow protruding strip, along which welding (3) of the profiles (1 and 2) is carried out, and which in turn conforms a deformation zone through which the guide can make an opening movement, which in cooperation with the mouth (6) of the groove (5) facilitates the controlled exit of the
curtain.
