Abstract

Stop for roller shutters, which are used to limit their travel, consisting of a piece of cuneiform or frustoconical plastic, characterized because, the arrangement, distribution and order of the specific and unique parts that make it up and that give it its peculiar form and properties is the following: the cuneiform stop (1) has a rectangular retention area (1.1) which is located in a horizontal plane in the working position. On both sides of said retention area (1.1) and oriented downwards, there are two fins (1.2) of triangular shape arranged in two parallel vertical planes and perpendicular to the plane of the retention area (1.1). the retention area (1.1), as an extension of the same in the direction of its major axis, has a hook (1.3) oriented upwards, protruding from its horizontal plane. In said hook (1.3) there is a narrowing that constitutes the crimp neck (1.4), of the stop (1.1) in the groove (2.1) of the blade (2). (Machine-translation by Google Translate, not legally binding)

Description

BUMPER FOR ROLLER

OBJECT

This invention has as an object a stop for roller shutter, which is fixed on the outer side of the lower slat to avoid that when raising the blind, it can be passed from the top of the window opening which would make it difficult to lower it again.

The industrial sector to which this invention belongs, is that of construction materials, and in particular that of accessories for doors and windows.

BACKGROUND OF THE INVENTION

The stops for roller blinds exist since such a blind was invented, however all of them without exception are fixed according to their type with one or two screws to the lower slat. Most of the types of stop that exist are cylindrical and made of plastic or wood material and fixed to said lower slat by means of a thyme and a nut. Another type of stop mostly used in wooden blinds, is the metallic one, with an angle of 90 °, and is fixed to the lower slat with two screwed wood screws or through screws and nuts.

All these types of stops, due to the blows that they receive when they make contact with the lintel of the opening of the window when raising the blind to its maximum maximum position, the inclemency of the weather, action of the sun, strong changes of temperature etc., They end up deteriorating in a short time.

In order to facilitate the maintenance of roller shutters and the replacement of said stops, a new type of stop is described below.

DESCRIPTION OF THE INVENTION

PROBLEM APPROACH: In many cases the stops for housing blinds are broken or do not exist and nothing is done about it to repair them, thinking that this problem is of little importance.

The stops of the blinds are fundamental in their operation since without them, when raising a blind, there is always a risk that it will pass from its upper limit position and be completely inserted in the drawer of the blind, fully wound in the roll holder , resulting after very complicated repair.

Due to the passage to the action of the sun, the oscillations of temperature and the inclement weather, these stops are degraded leaving in many cases only the fixing screw. Although there are different types of stops, all are fixed to the lower plank with screws, which requires tools and some ability to perform manual work.

ADOPTED SOLUTION: The solution consists of a plastic stop that is manually interlocked with a slight turn of the wrist in an outer horizontal groove of the lower slat of a roller shutter, either plastic or aluminum. There are two versions, although you can adopt multiple variants in terms of shape and materials.

The first version is cuneiform (see Figure 11). It basically has a retention area and a hook-shaped end that is introduced through the groove of the slat, and exerting a gentle downward pressure, is blocked by its neck in said groove.

The second version is shaped like a truncated cone, see Figures 2A and 2B. It has a double hook that is easily inserted into the groove of the slat, and by turning the stopper 90 ° manually around its axis, it is locked in said groove.

TECHNICAL CHARACTERISTICS:

The cuneiform stop, has a retention area to limit the path of the blind, which is rectangular in shape and is located in a horizontal plane in working position. On both sides of said retention zone and oriented downwards, there are two triangular-shaped fins arranged in two parallel vertical planes and perpendicular to the plane of the retention zone.

Said retention zone, as an extension thereof in the direction of its major axis, has an upwardly oriented hook, protruding from its horizontal plane. In said hook there is a narrowing that constitutes the crimping neck, of the stop in the groove of the slat.

The truncated conical stop has, at one end, a double and symmetrical hook located in a plane perpendicular to its axis. Said double steel hook, has a screw perpendicular to the plane of said hook, which allows it to be screwed into a cylindrical hole coaxial with its axis, which has said stop.

The plane of the double hook is separated from the base, 2 mm, said separation constituting the crimping neck in the groove of the blade.

ADVANTAGES:

It is easily placed with a simple twist of the wrist, without needing tools. Your replacement can be done by anyone. It is much cheaper than the traditional top, since I don't know

They use thymes or moving parts.

In the upper part you can see a part of the wall (4) that constitutes the upper end of the window opening. Figure 5B is an illustrative view of the fully raised blind and the cuneiform stop (1), making contact with the lintel (4.1) of the wall (4), thus preventing it from being exceeded.

PREFERRED EMBODIMENT OF THE INVENTION

Among the different embodiments of this invention, the preferred one is described below:

The preferred embodiment of the stop (1) is the one with the cuneiform shape as seen in Figure 1 E, which is a side view. In figure 3B, said stop (1) is observed in working position, with its retention area (1.1), flat and horizontal, which facilitates contact with the lintel (4.1) of the wall (4), when a blind is lifted in order to limit its travel, that is, it is an end of career element.

The stop (1) has a fastener in the groove (2.1) of the lower slat (2) of a blind (3), consisting of a hook (1.3) and a crimping neck (l.4), which it fits into the groove (2.1) of the slat (2) due to the elasticity of the plastic when the hook (1.3) is inserted into said groove. The cuneiform stop (1), is thus perfectly fitted and immobilized, by its neck (l.4) and by

5 the two supporting sides (1.5) of the fins (1.2), when making both contact with the surface of the blade (2).

The triangular shape of the fins (1.2) that give the cuneiform configuration to the top (1) has a technical explanation, since in the area near the vertex of the triangle they form, the effort (moment

10 flector) is smaller, and at its base, the effort is greater.

Having sufficiently described the nature of this invention, as well as a practical application thereof, it only remains to add that

Materials, components, dimensions and arrangement thereof are susceptible to modifications, provided they do not substantially affect the characteristics claimed below.
