Description

The present invention relates to a slide-on safety device for a gate, in particular for a garage door, which has a drive slide, which is shut off in a running rail with the door closed, wherein at least one latching element, which is rotatably mounted in the drive carriage, is provided according to claim 1.

As is known, drive devices for locking the door are used to open and close gates. In the end position, these drive devices must additionally lock the door securely. The locking is often done by a self-locking worm gear motor, which is coupled via traction means, via a carriage located in a guide rail and a connecting element with the door leaf. In a manual opening attempt, the gearbox is blocked, thus locking the gate.

Locking via the self-locking mechanism of the geared motor works well enough with attempts to break-in initiated by manual force. But if one Postponement attempt is made with suitable Aufbruchswerkzeuge, it may well be that the self-locking function of the door drive fails.

Therefore, additional locking devices are used to increase the security against breakage of a door, in particular a garage door, and even prevent a break. The locking devices must be designed such that they block a movement of the carriage on the running rail when the door leaf is to be released from the closed position by manual action of force. The previously known locking devices work with integrated in the carriage of the door drive pawls or detents. Here, the pawl or detent goes into a blocking position as soon as the opening movement was not initiated by the door drive, but emanates from the door leaf.

Such locking devices are for example from the DE 10 2007 010 209 B4 as well as from the DE 195 18 493 C2 known. These each reveal a locking device with integrated pawl in the carriage. The pawl is rotatably mounted at one end in the carriage, wherein it is connected at the other end with a gate operator. The gate operator is coupled at its other end to the door leaf. The pawls or detents described in these publications work in the blocking position each with a stop to be mounted in the guide rail. However, this stop must also be mounted and adjusted precisely so that the pawl or the catch securely engages with the stop. The adjustable stop is only available once and only in the position "Gate CLOSED", so that it is not possible to engage or catch in any position. Thus, even in the winter months necessary ventilation of the garage in the locked state of the door is not possible.
Furthermore, the previously known locking devices are constructed such that it can also come to Auslenkbewegungen the pawl, when forces are directed from the outside into the carriage and the gatekeeper, which generate the drive to open and close the gate, so that it unintentional Movements of the pawl and thus also relative movements of carriage and door leaf comes. A push-on safety device according to the preamble of claim 1 is in DE 10 2007 025 723 disclosed.

Object of the present invention is therefore to provide a slip-on for eir Tor, especially for a garage door, which has a simple structural design and at the same time provides effective protection of the door against a break-in attempt.

This object is achieved by a slip-on with the features of claim 1.

The slip-on safety device according to the invention can be used for a gate, in particular for a garage door, wherein the gate has a drive slide, which can be parked in a running track when the door is closed. The slip-on protection has at least one latching element which is rotatably mounted in the drive carriage. The running rail has at least two recesses in which the latched at least one locking element during Aufschubversuch. Thus, no additional stops must be provided in order to realize a latching connection. By eliminating additional stops to be set, the manufacturing and assembly costs are significantly reduced.

Furthermore, a slip-on protection is realized in a simple manner, which meets the high requirements in terms of protection against break-in. By locking the locking element in the recess provided in the running rail a play-free coupling of the door can be realized with the door drive.

In the positions in which the drive carriage can be parked in the running track with the door closed, the recesses are located in the running rail. If there is a deflection of the locking element in an opening attempt, the locking element passes into a nearest recess and thus in a catching position, which is almost identical to the position - gate closed - is. The at least two recesses in the running rail are formed as catching openings. The catch openings are preferably formed at a location in which the drive carriage can be parked in the running track at the closed gate. A latching or catching of the at least one latching element can also be realized in a partially open position of the door, the so-called ventilation position, and not only - as in the previously known solutions - in or near the position "door CLOSE". The opening may preferably be about 20 to 30 cm. Thus, with the solution according to the invention, a garage ventilation can also be realized in the locked state. This is especially necessary in the winter months, as the dripping of ice and snow can cause moisture in the garage.

A preferred embodiment of the slip-on protection according to the invention provides that the catching openings are formed on the upper flange of the running rail and indeed at a distance from one another, preferably at regular intervals. Thus, the locking element can pivot in the next catch opening in the blocking position.

The catch openings in the running rail are preferably pre-cut and are dimensioned such that a secure engagement of the at least one latching element can be realized. In this case, the at least one locking element preferably has a projection which engages in the catch opening, so that the latching connection can be realized. The catch openings of the Aufschubsicherung invention each have a cut-free piece of sheet metal, wherein the piece of sheet metal when snapped the at least one latching element remains in the closest catch opening within the opening. In this case, the sheet metal piece is pushed out by the locking element in the event of a catch. The anti-slip device according to the invention is characterized in that the catch openings each have a pre-cut finger trap protection, so that when the detent element engages, the pre-cut finger trap protection ensures a secure hold of the detent element.

The locking element may preferably be a pawl or a grid which is fixedly connected at one of its ends to a gate driver and at the other end rotatably connected to the drive carriage, which is rail-guided. The rotational movement can be easily realized for example by means of a hinge pin.

Preferably, the catch openings of the anti-slip device according to the invention are formed in cross-section trapezoidal or elliptical, or semicircular. Another suitable form is also conceivable and feasible.

It is considered to be particularly preferred if the catch openings of the slip-on safety according to the invention are shaped identically and arranged along the running rail so that the pawl or the grid engages in the next catch opening during the push-on test.

Preferably, the latching element has a recess in which a flexible element can be at least partially accommodated, so that the latching element can be pressed against the flexible element during the push-on test and arrives in a blocking position by latching into the nearest catching opening. By providing the flexible element, a secure mounting of the locking element can be ensured in the catch opening, so that the door can not be opened from the outside, even if suitable Aufbruchwerkzeuge be used.

The flexible element can preferably be held on the upper carriage edge by means of a holder, in particular a mounting plate. The recess of the latching element is preferably dimensioned such that it is adapted to the shape of the flexible element. It is particularly preferred if only a part of the flexible element is inserted into the recess of the latching element, so that the flexible element is positioned in the recess and is held firmly by the mounting plate provided in the drive rail.

As a flexible element, a resilient damping element, in particular a coil spring can be used.

However, it is also conceivable and possible to use a flexible element made of plastic, in particular of polyurethane, wherein the damping element made of plastic may have different cross-sections. The damping element may for example have a substantially rectangular or circular, or else an elliptical cross-section. Preferably, the damping element consists of an approximately 5 mm thick polyurethane, although other plastics and dimensions can be used for the flexible element.

A further preferred embodiment of the slip-on protection according to the invention provides that the flexible element, which is received in the recess of the locking element, is integrally formed and made of sheet steel, preferably of a 3 mm thick sheet steel. Designs made of other materials are also possible and feasible.
