Abstract

The door structure (10) has a door leaf (14) guided by a door leaf guide (12). The door leaf is formed such that it is impinged by a wire rope (16) in an open position. The wire rope is arranged in pulley block-shaped manner. The pressure impingement of the door leaf in an opening direction is obtained by a gas pressure spring (18) arranged on the wire rope. The movement of the door leaf in the opening direction generates a spring movement of the gas pressure spring.

Description

Technical area

The present invention relates to a gate construction with a gate which is guided in a gate wing guide. In this case, the gate is designed such that it is acted upon by means of a cable in an open position.

Such door structures are mainly used in one-piece single and / or double garage doors, wherein the door leaves can be both designed so that they swing out when opening to the outside or not.

State of the art

A variety of gate designs are known in the art, examples of which are single, double, and sectional door designs. By means of a single or double construction, it is possible, for example, to close a single or double garage. In both the single and double garage, the door construction can consist of a substantially flat door leaf or gate leaf or of a sectional door leaf or gate leaf. To reduce the risk of accidents during manual or motor-assisted opening, the door designs are designed in such a way that, as well as the opening operation of the gate is initiated from the closed position to the open position, the gate is pulled by means of a force-applying means in the open position. In this way can be effectively prevented that when the opening process for example, is interrupted by a human failure or a motor failure, the gate "falls" down and squeezes underneath people, animals or vehicles.

As Kraftbeaufschlagungsmittel usually a spiral or coil spring or a counterweight is used. Disadvantage of the spring is that this, similar to the balance weight, requires a large installation space, since for reasons of longevity and cost usually long spiral or coil springs are used. Furthermore, it is necessary, for example, for non-pivoting gates that long spiral or coil springs are used, since only by providing a long spring travel, the (thus lower) pressure forces on the spring when closing the gate are economically manageable. Finally, springs still have the disadvantage that they do not gradually their service, so successively fail, but tend to a sudden failure by spring break. However, this sudden failure leads to a high risk.

Furthermore, from the DE 10 2007 047 100 A1 , of the DE 9196210 U1 and the DE 3943257 A1 Door constructions known in which the weight balance is effected by means of gas springs. In all these gate designs, however, it is necessary that the gas spring must be compressed over a relatively long distance and that the gas spring is arranged freely in space. This leads to an increased load on the gas spring.

Furthermore, from the DE 199 53 015 A1 a Torkonstruktion known in which a gate is opened by means of a trackless mechanism. In this mechanism, a weight compensation spring is provided, which can be designed as a helical spring or as a gas spring and is designed so that in different Positions can be suspended, so that the door leaf is held in the middle position in about suspension. Again, however, it is necessary to provide such a large space for the weight compensation spring, so that they can act across the entire pivoting range of the gate.

Presentation of the invention

The invention has for its object to provide a gate construction, which solves the known problems of the prior art and is also adapted to provide a safe, durable and low-maintenance door construction, which is also designed so that they possible little space needed.

The object is achieved by the subject matter of patent claim 1. Preferred embodiments of the door construction according to the invention emerge from the subclaims.

The invention is based on the idea to use durable components so cleverly that a reliable and safe door construction can be provided.

Accordingly, the gate construction according to the invention comprises a guided by a gate wing guide leaf, wherein the gate is designed such that it is acted upon by means of a cable in an open position, the cable is arranged like a bottle and a pressurization of the gate in the opening direction by means of a cable arranged on the gas spring is obtained, wherein a movement of the gate in the opening direction produces a spring movement, in particular a compression movement, the gas spring whose amount is smaller than the amount of the gate leaf movement.

A "gate" within the meaning of the invention is any type of one-piece and multi-part gate, which is attached to an outwardly swiveling or not swiveling gate construction. Further, a "cable" refers to any type of guide that guides a cable, a belt, a grooved belt or the like. By a "pulley-type arrangement" of the cable is meant any arrangement of the cable which makes it possible to produce a gear ratio between the movement of the gate and the spring action of the gas spring.

With the door construction according to the invention, it is possible to use a gas spring due to the transmission ratio of the pulley cable-like cable, which requires very little space or space in the gate construction. Furthermore, the installation effort when installing the gate construction is low, as a result of the size of the gas spring, a high degree of pre-assembly of the gate construction is possible and on the other hand, the gas spring can be easily installed due to their low weight on site. Furthermore, the gas pressure spring is able to absorb much higher compressive forces than the normal spiral or coil spring with comparatively much smaller shoring volume and in contrast to the helical or helical spring does not tend to abruptly fail (by breakage), which is advantageously prevented in that the gate leaf "falls down" and squeezes people, animals or vehicles underneath. In addition, a gas spring usually also has a longer durability than a coil or coil spring.

Furthermore, the flaschenzugartige arrangement of the cable has the advantage that the forces when opening and / or closing the door construction can be particularly advantageously introduced into the gas spring.

According to one embodiment, the gate assembly is arranged to guide the gate to an open and / or closed position. In this way, it is particularly advantageous possible to safely guide the gate from an open to the closed position and vice versa.

For this purpose, according to a further embodiment, the gate can be guided on two sides in at least one rail.

According to another particularly preferred embodiment, the gas spring has a spring progression of less than 30%, preferably less than 15%. In this way, it is possible to adjust the force required for manual or motor-assisted opening or closing of the door leaf over almost the entire opening or closing path as required by appropriate adaptation of the door construction structure. In this way it can be ensured that the opening or closing speed of the door leaf is always approximately constant and not towards the end of the opening or closing, in areas where it is not advantageous, much higher or lower forces needed. In this way, the ease of manual opening is much easier and the design of the garage motor is simplified.

Further, according to another embodiment, the gas spring may be arranged substantially perpendicular to a plane described by the gate in the closed position or the gas spring may be arranged obliquely with respect to a closed position of the gate. In this way, it is always possible depending on the selected gate leaf type and the available space to choose the optimal arrangement of the gas spring, so that the forces during opening and closing optimally in this can be initiated. Furthermore, this type of arrangement has the advantage that neither the gas spring nor the cable to reduce the ceiling height of the available space in which the door construction is attached, zoom.

Furthermore, the gas spring in a linear guide means, in particular a rail, preferably a rail to be guided with plastic guide to increase their durability in addition, since by guiding the gas spring in a rail tilting of the gas spring in the spring movement is avoided and thus the gas spring is loaded only in the optimum direction.

According to a further particularly preferred embodiment, the number of load-bearing ropes, belts and / or belts of the pulley-type cable is at least two, preferably three. In this way it is possible to obtain an optimal ratio between the space requirement of the cable due to the number of supporting cables and the maximum pressure of the gas spring due to the transmission ratio.

According to one embodiment of the invention it is further provided that the door construction is designed as a non-swinging gate construction, since the advantages of the construction according to the invention, for example, over long spiral or coil springs, are particularly pronounced here.

Detailed description of preferred embodiments of the invention

Below is a description of a gate construction according to the invention 10 based purely on exemplary embodiments with reference to the Figures 1-3 , Other alternative embodiments are also possible.

Fig. 1 shows a gate construction 10, in which a gate 14 is arranged in an open position.

The opening and closing movement of the gate is guided by means of a gate leaf guide 12, which in the embodiment shown comprises two rails 20, such that the gate 14 does not pivot outwardly. The door leaf 14 is thus designed such that a vehicle parked in front of a garage when opening the door leaf 14 of the garage is not damaged.

The door leaf 14 is guided on opening in the rail 20 via rollers 30.

At the door construction 10, a cable 16 is also provided in conjunction with a gas pressure spring 18. The cable 16 is constructed such that a cable 24 is guided over rollers 28 such that a flaschenzugartige arrangement is formed in conjunction with the gas spring 18. In this case, the gas spring 18 acts in conjunction with the cable 24 and the Cable 16 such that it supports a movement of the gate 14 in the opening direction, since the spring is extended in the embodiment shown when opening. Of course, it is also possible to arrange the gas spring and cable so that the gas spring contracts when opening. Of course, the course of the force required when lifting the gate 14 of course also be designed so that the force when opening in a lower area is initially low, then rises and ultimately the gate 14 slides independently and without further effort in the open position.

Depending on the available space, the gas spring 18 and the cable 16 can be arranged perpendicular or in accordance with the inclination of the gate guide 12 at an angle which substantially corresponds to the inclination angle of the gate guide 12.

In order to obtain a uniform opening or closing force over the entire range of movement of the gate, the gas pressure spring 18 is designed such that it has a spring progression of less than 30%, preferably less than 15%.

This has in contrast to conventional gas springs, as they are known for example from the automotive sector, the advantage that as well as the gas spring 18 is fully compressed, the necessary compression force in approximately proportional and not square or more increases.

By providing a linear guide means, in particular a rail 22, it is possible to guide the extension and compression movement of the spring such that the gas pressure spring 18 is loaded only in the desired direction and not transversely thereto.

In the in Fig. 1-3 In the exemplary embodiments shown, the cable pull 16 is always arranged essentially in approximately the gas pressure spring 18. Of course, an arrangement of the cable is conceivable in which this is not arranged substantially directly above the gas spring 18, but at an angle thereto. In this case, for example, a suitable deflection means for the cable 24, for example in the form of a roll to provide.
