Abstract: In a method for producing an identification carrier or electronic key for electrically actuatable locks, an integrated circuit having at least one memory component is applied on a carrier by a printing process and an identification code is stored in the memory component.

Abstract: In a device for access control comprising an electrically actuable lock and a key (12, 16) the lock and/or the key (12, 16) have/has a power supply comprising at least one thin-film solar cell (6, 10, 11, 15, 20, 21) which is fitted or applied to an area of the key (12, 16) that is exposed to the light and/or of a part electrically connected to the lock or below an energy-transmissive area of the lock, of the key (12, 16) and/or of a part electrically connected to the lock or forms said area.

Abstract: In a device for the electrical connection of electrical or electronic components which are arranged on different sides of an electronic lock in pivotable or rotational operating members for the lock, which are connectable in a rotationally fast manner with a locking nose (6) of the lock via an interposed coupling shaft (3) passing through the lock, the coupling shaft (3) comprises an axial groove in which electrical wires or cables (1) are inserted. The coupling shaft (3) carrying the wires or cables (1) carries a sleeve (4) slipped on the coupling shaft (3) and reaching into a hollow shaft (7), the coupling shaft (3) is connected in a rotationally fast manner with the electrical or electronic components to be connected, or their boards, and the hollow shaft (7), which is connectable or connected with an operating member, operates the locking nose (6) for the lock and can be coupled to the coupling shaft (3) carrying the electronic components.

Abstract: In a device for securing the handle or knob (9) of a door or window, comprising a locking element (18) that is disposed transversely to the axis of the handle or knob (9), a locking spring element (13) is disposed in a base part or a knob shield (1), the locking spring element (13) carries locking lugs (8, 7) that dip into radial openings (2, 6) of the base part or the knob shield (1) the locking element (18) interacts with the locking spring element (13) in such a manner that the locking spring element (13) is deformed when the locking element is displaced transversely to the axis of the handle or knob (9) and locking lugs (8, 7), disposed on the periphery of the locking spring element (13), disengage from or engage with recesses (10) on or in a part of the handle or knob (9) encircling the locking spring element (13) and the base part or the knob shield (1).

Abstract: A key has a blade formed with a part-cylindrical face and with a pair of relatively shallow, outwardly open, and generally parallel but spaced grooves formed in the face extending generally longitudinally in a nonstraight path and a relatively deep and outwardly open groove formed in the face and extending generally longitudinally in a nonstraight path generally nonparallel to the shallow grooves. The grooves each have a plurality of control positions at which they extend substantially parallel to the blade and are inclined to the blade between the respective control positions.

Abstract: A lock core rotatable in a housing is formed with an axially extending key passage, transverse guide slots, and an axially inwardly open bore. A bolt displaceable in the bore between a locked position and a unlocked position has radially open grooves aligned with the slots in the locked position. The inner bolt end can directly engage in an inwardly open seat formed in the housing or with a ball engageable in such a seat to lock the core in the housing. Tumbler plates in the slots are formed with control edges and holes alignable with the bore in a freeing position. The plates are displaceable into blocking positions with the holes offset at least partially from the bore and engaging in the respective grooves. A key has a plurality of respective bit notches engageable with the control edges on engagement of the key in the passage.

Abstract: A lock has a flat key having a flat blade extending along a key axis and having an axially extending edge formed to each side of a central axially extending key plane with a pair of axially extending inner edge surfaces flanking the key plane and each formed with a plurality of bits offset transversely at different spacings from the key axis. The bits on one side of the key plane are offset axially to the bits on the other side of the key plane as described above. A barrel having an inner surface centered on a lock axis holds a plug rotatable about the lock axis in the barrel, bisected by a plug plane including the lock axis, and formed with an axially extending and open key hole adapted to receive the key with the axes coaxial and the planes coplanar. A respective set of axially spaced tumblers is dis-placeable in the plug to each side of the plug plane parallel to the plug plane. The tumblers of one of the sets engage the key in the hole at locations offset axially from the tumblers of the other set.

Abstract: A key has a flat key body having a blade extending along a longitudinal insert axis and having a front edge formed with transversely directed bitting, an opposite longitudinally extending back edge, and a pair of oppositely directed faces. Each face is formed with at least two longitudinally extending front grooves extending adjacent the front edge a full length of the blade and having depths equal to more than half of a transverse thickness of the blade, a longitudinally extending back groove having a floor at a depth equal to less than half of the blade thickness, and an elongated angled groove extending at an acute angle to and across the respective back groove at an intersection and having a part-cylindrical floor aligned with and forming a smooth continuation of the floor of the respective back groove at the intersection.
