Abstract: A finger protection device for bridging a gap of a door or window that has a winding shaft with a first end face and a second end face and a roller blind web that can be wound via the winding shaft. The roller blind web is arranged with a first end on the winding shaft and on the winding shaft side can be attached, together with the winding shaft, to a first part of the opening. The roller blind web can be attached with a second free end to a part of the opening. The finger protection device has a first and a second holder, wherein the first holder arranged on the first end face of the winding shaft and the second holder is arranged on the second end face of the winding shaft.

Abstract: A sealing device of a sliding door having a slidably mounted door leaf has a drop-down seal having a sealing strip and a lowering mechanism for automatically lowering and raising the sealing strip. The lowering occurs against a restoring force. The sealing device also has an activation unit for activating the drop-down seal. The activation unit has a contact surface, which is directed upward in the lowering direction, and a contact element, which lies against said contact surface during the closing of the door leaf and thereby actuates the drop-down seal. In this way, the weight of the door leaf can be used for the lowering of the sealing strip. Furthermore, a position in which the restoring force does not influence a sliding motion of the door leaf in the longitudinal direction of the sealing strip can be achieved.

Abstract: A key (1) for a rotary cylinder lock (2) comprises a key grip (3) and a key shank (4), which adjoins the key grip (3) and extends along a longitudinal axis (L), wherein the key shank (4) has, on its outside (5), control recesses (10), in particular control bores, for properly positioning tumblers on the rotary cylinder lock (2) and also has at least one control element (6) arranged in a movable manner in the key shank (4), which control element (6) has a control surface (8), which interacts with a tumbler (7) of the rotary cylinder lock (2). Furthermore, the key is characterized in that the key shank (4), in the region of the control element (6), has a tapered cross section (9), which is tapered in relation to the cross section (11) with the control recesses (10).

Abstract: The invention relates to a mechatronic locking device comprising: a locking cylinder having a control circuit and a security key associated with the locking cylinder having a memory circuit, wherein informational signals can be exchanged between the control circuit of the locking cylinder and the memory circuit of the security key via a communication channel, wherein the security key further comprises a contact element which is connected to the memory circuit of the security key via a contact section integrated on the security key, wherein the locking cylinder further comprises a contact element which is connected to the control circuit of the locking cylinder, wherein the contact elements are electrically in contact to each other when the security key is inserted and wherein said communication channel conducts between the control circuit and the memory circuit via the contact section integrated in the security key and the two contact elements.

Abstract: The mechatronic locking apparatus comprises a control circuit (4), from which information signals can be transmitted to a control circuit (6) of the lock cylinder (2) using a first communication path (5). A security key (3) has at least one second communication path (7) for storing and/or processing access data. The two communication paths (5, 7) are connected to said control circuit (4) of the security key (3). The first communication path (5) preferably uses an electrical contact in the lock cylinder (2). The second communication path (7) comprises a transponder (8). The first communication path (5) may also be used for power supply purposes.

Abstract: The invention relates to a closing device which comprises a stationary part (2) and a pant (3) which is displacably mounted thereon. Tumblers (Z1-Z5) are arranged by means of a key (19) in order to release the displaceable part (3). Said tumblers (Z1-Z5) are maintained in a locking position by means of the locking element (14, 27, 33). The locking element (14, 27, 33) can be adjusted by means of a drive (13, 23, 30) in order to release the tumblers (Z1-Z5), which can be controlled via an electronic control device (16).
