Abstract

A device (1) for emergency locking of, in particular, electrically operated sliding doors (2) is described. In order to enable reliable locking of the sliding door and thus protection against burglary in the event of a defect in the sliding door or a long-term blackout, it is proposed that the device comprises two holding profiles (3), each of which has a holding leg (4) which forms a stop for a respective door leaf (6) that acts against the opening direction (5) of the latter, wherein, in order to close the sliding door (2), the holding profiles (3) can be clamped against one another via a clamping device (10) having a tensile clamping element (9), wherein the clamping device (10) is placed on the holding profile (3).

Description

Description [0001] The invention relates to a device for emergency locking of, in particular, electrically operated sliding doors. [0002] Electronic sliding doors are used in banks and business branches, shopping centers, etc. In the event of any defects in the sliding door that occur outside of business hours or at the weekend, the problem regularly arises that the repair of the sliding door, which requires a specialist, is then associated with high costs due to the surcharges. Conversely, however, there is an immediate need for action, since the defective sliding door usually makes it easy for unauthorized persons to enter the room or building separated by the sliding door. [0003] A further problem arises in the case of widespread, long-term power outages or blackouts. If a corresponding emergency battery for operating the sliding door is empty, the sliding door can no longer be closed using the battery, and the door leaves then remain in an open position and cannot be locked in a closed position. [0004] There is therefore a need for a device of the type described above which, in the event of a defect in the sliding door or a long-term blackout, enables the sliding door to be reliably locked and thus provides protection against burglary. [0005] The invention solves the problem by two holding profiles, each of which has a holding leg which forms a stop for a respective door leaf acting against the opening direction thereof, wherein in order to close the sliding door the holding profiles can be clamped against one another via a clamping device having a tensile clamping element, wherein the clamping device is placed on the holding profile. [0006] Due to these features, the device can fix a sliding door in its closed position, so that a potential break-in is prevented in the event of a defect or a long-term blackout. The two holding profiles, which engage the respective door leaves by means of a holding leg, can fix the door leaves in the closed position of the sliding door by means of a tensioning device. The device can be attached from the inside of the sliding door, so that the tension can only be released and the sliding door unlocked from the inside. The tensioning device has a tension-resistant tensioning element for this purpose, which transfers the tensile forces generated by the tensioning device to the holding profiles, with the force being transferred via the door leaves. The tensioning forces generated in this way therefore act against the opening direction of the respective door leaf and thereby fix the sliding door in its closed position. [0007] A cost-effective embodiment, which has commercially available and readily available components, can be provided by the tensioning device being formed by a tensioning ratchet and a tensioning belt as a tensile tensioning element, with at least one of the holding profiles having a fastening receptacle for a free end of the tensioning belt. The widespread use of tensioning belts and tensioning ratchets both in the range of retail chains and in the basic equipment of private and commercial warehouses makes these standardized belts and ratchets easily available components, which in combination with the holding profiles according to the invention enable a cost-effective overall device. [0008] In this context, a particularly advantageous force transmission from the holding profiles to the respective door leaves of a sliding door can be achieved by arranging the tensioning ratchet on the side of a holding profile facing away from the holding leg. The resulting force vectors can, on the one hand, press the holding profiles onto the door leaves of the sliding door and, on the other hand, run essentially parallel to the opening direction of the respective door leaf, so that it is fixed in the closed position of the sliding door with the lowest possible transverse forces. [0009] A violent opening of the door in the course of a break-in can be made more difficult by the fact that the tensile tensioning element runs through a cut-resistant guide, which is preferably x 'Hex AT 527 223 B1 2024-12-15 8 NN is movable along the longitudinal direction of the tensioning element. The cut-resistant guide can be arranged in the area of the door gap so that the introduction of a sharp object such as a knife from the outside cannot enable the sliding door to be unlocked by force as a result of the tensioning element being cut through. An advantageous embodiment can be such a design of the cut-resistant guide in which it is wider than the tensioning element and is located at least in the area of the door gap between the tensioning element and the sliding door. Various materials can be used as cut-resistant materials, examples of which are cut-resistant plastics, in particular Kevlar, or metal rails through which the tensioning element can slide. [0010] A stable hold of the holding profiles on the door leaves with a low material load on the sliding door is made possible in a struct
