Abstract: In a brace part for the driving rod brace (4) of a window, the housing (10) is attached to a jacket rail (9) via brackets (16, 17). The jacket rail (9) has recesses (18, 19) through which the brackets (16, 17) are guided. The brackets (16, 17) with bends (22, 23) extend behind shoulders (20, 21) which are located in the recesses (18, 19). In this way the housing (10) is positioned especially exactly on the jacket rail (9) and avoids components which project over the jacket rail (9).

Abstract: In a lock with a locking cylinder (3), the locking cylinder (3) has a knob (30) on one side and on the other side has a lock channel for insertion of a key (31). The lock has two split hubs (4, 5) on top of one another for triggering a locking element (6). Furthermore, the lock has a positioning element (24) which establishes whether blocking of the locking element (6) produced by the locking cylinder (3) can be canceled by actuation of the split hubs (4, 5). A projection (21) which is located on a plate (20) which interacts with the positioning element (24) establishes from which side this blocking can be cancelled.

Abstract: A rod system device extending from its lock unit to a tensioning devicc of the door catch mechanism which takes up two positions is connected in the door catch mechanism with a pivotable unlocking hammer so that the door catch mechanism can be released from the drive rod locking mechanism. The door catch mechanism has an unlocking lever which, when engaged with a bolt element, is ready for contact opposite a trigger element of the tensioning device so that following the unlocking of a bar/drive rod locking unit with the lock unit, the bolt element can be moved from the engagement position to a release position by deflection of the unlocking hammer.

Abstract: An electronic lock cylinder comprises a housing (1) with a cylinder core (9) disposed rotatably therein and lockable by a key (15) via mechanical tumblers (21). Electronic control circuits (45, 47) capable of being coupled inductively via coupling coils (43, 49) for the transmission of coding information, are associated with the lock cylinder and the key (15). The coupling coil (43) of the lock cylinder, and the electronic components included in the lock cylinder and a mounting (51), are combined into a structural unit which is removably attached to a front face of the lock cylinder. This permits separate assembly of the mechanical components and of the electronic components of the lock cylinder.

Abstract: A luggage carrier which can be adapted to different sizes of bicycle frames and shapes is provided. A supporting frame of the luggage carrier is supported in the region of the rear wheel bearing by supporting frame supports. The front end region of the supporting frame is connected by means of a swivelling part to a pair of bars of the bicycle frame extending from the region of the rear wheel bearing to the upper end region of a saddle tube. The position of the swivelling part is adjustable along the length of the supporting frame, and the swivelling part is secured at a desired position for operation. The swivelling part is swivellable around an axis orthogonal to the longitudinal central plane of the luggage carrier.

Abstract: A lock cylinder comprises a profile housing (1) with a cylinder core (9) disposed rotatably therein, and tumblers (15) which are controllable by a flat key. Disposed on the profile housing (1) is an information detector (37) which responds contactless to control information signals of a control circuit of the flat key, which is connected to an electronic control and power-supply circuit having at least some of its circuit components disposed separate from the lock cylinder. These circuit components are connected by a cable (43) and a plug connector (45) consisting of two plug parts (49, 51) complementary to one another. A first plug part (49) is mounted fixed on the profile housing (1), and the cable (43) bears a second, loose plug part (51) capable of placement on the first plug part (49).

A circuit chip (23), fitted with structural parts (25) of an electronic circuit, is in a recess (21) in the bow section, formed by an integral bottom (19) of the basic shaped part (11) and sealed by a casting compound (29). Housing shells (15, 17) surrounding the bow section (13) are on facing flat sides of the bow section (13). The housing shell (15) lying over the recess (21) is bonded to the bow section (13). The other housing shell (17) bears a U-shaped rib (43) by which it engages behind the bonded housing shell (15).

Abstract: A device (16b) for tilting windows, doors, ventilation hatches, or similar closures open, with a motorized transmission-activating mechanism (12b) and a transmission (14b) comprising two back-to-back chains that curve in opposite directions.

Abstract: A window system is proposed in which windows (41) which can be both locked and tilted mechanically are connected via microprocessors (43) to a monitoring center (49) which can display the locking and closure status of the individual windows (41) via visual display units (51, 57). The microprocessors (43) are located in the vicinity of the windows (41) and connected to the receiver (61) of a radio-controlled remote control unit by which the windows can be remotely controlled. The windows (41) can also be controlled via an operating unit (65) in the monitoring center (49). The remote control unit may involve either portable transmitters (63) or transmitters with a fixed location (67) which control the windows (41) via sensors (69) as a function of ambient air parameters, such as the relative air humidity, temperature or the CO.sub.2 content of the air in the room. The windows (41) have a locking drive integrated in the handle and a separate tilting drive.

Abstract: A window or a door comprises a stationary frame and two leaf frames. The leaf frames are mounted for pivoting movement about mutually parallel pivot axes. A first leaf frame is intended for more frequent opening and closing, and a second leaf frame is intended for less opening and closing. The second leaf frame can be locked with respect to the stationary frame by drive rods which move in opposite sense and which engage the stationary frame at the respective ends thereof. The first leaf frame is provided with the vertical height of the first leaf frame. This first drive rod is driven by a first drive mechanism. The first drive rod controls transverse bolts for engagement with the second leaf frame. The transverse bolts driven by the first drive rod are located outside the first drive mechanism.

Abstract: A shackle lock, particularly with a long shackle, comprises a lock body and a lock shackle with two shackle arms, the free end portions of which are displaceable into a shackle arm housing of the lock body until they reach a locking position of the lock shackle. A lock mechanism is rotatable about an axis of rotation, particularly by a key. Disposed in the lock body is at least one locking element which meshes with the closure mechanism and which, upon actuation of the closure mechanism, is guided for movement out of a lock shackle arresting position in which the locking element is in engagement with the end portion of at least one shackle arm for locking the lock shackle and for movement into a lock shackle releasing position in which the locking element is out of arresting engagement with the end portion of the shackle arm. In this lock shackle releasing position the shackle arm can be withdrawn completely from the shackle arm housing.

Abstract: In the case of a locking device for a lock, especially a ring lock, comprising a connecting part (14) and a connecting part case (16) with a snap-in locking device (22, 24, 30), operated with a locking mechanism (32) a ratchet body (22) is accomodated in a guide passage (26) of a ratchet body guide element (24) oriented transversely to the direction of insertion of the connecting part (14) and is opposite a guide surface (30 at 31) at its side remote from the inserted connecting part (14). The guide surface (30), when the ratchet body guide element (24) is in a locking position, urges the ratchet body (22) behind a ratchet shoulder (20) of the connecting part (14) into an engagement position which prevents withdrawal of the connecting part (14).

Abstract: A pivoted fitting or turn-and-tilt fitting for windows, doors or the like comprises a bottom turn-and-tilt bearing and a top pivot bearing, both bearings being in each case constructed with two links in order to shift the pivot axis during pivoted opening of the leaf frame. In order to relieve the links of the weight of the leaf, it is suggested that the leaf frame be supported on the fixed frame via an arrangement which is independent of the links of the two pivot bearings.

Abstract: The profiled cylinder (38) seated in an insertion opening (87) of the lock housing (7) is guided by a retaining bracket (93) and fixed centrally by a detent pin (121) on the retaining bracket (93). The detent pin (121) is guided displaceably on a slide piece (103) and initially stressed by a spring (131) towards the profiled cylinder (38). The profiled cylinder (38) contains a reading device for en electronic key, which device is connected through a plug-in connection (89) with an electronic circuit of the lock. The plug-in connection (89) and the detent pin (121) are so adapted to one another that the detent pin (121) firstly fixes the profiled cylinder (38) on the pedestal (93) before the slide piece (103) guided in centered manner in relation to the pedestal (93) closes the plug-in connection (89). In this way defects of alignment of the plug-in connection (89) and damage to its contact elements (107, 109 ) are avoided.

Abstract: In a drive rod lock the drive rod is moved from a lock cylinder through a step-down gearing between an open position and a closed position and vice versa. A coupling of the step-down gearing to the drive rod is proposed which permits, in the case of rotation of the lock cylinder through 2.degree..times.360.degree., of shifting the drive rod from the open position into the closed position against displacement, without a torque being introduced due to the blocking forces into the step-down gearing and thus the lock cylinder.

Abstract: The cable lock has a flexible cable portion and an elongated lock body at one end of the cable portion which is enclosed by a two-part synthetic plastics casing. The plastics casing comprises a cap-shaped outercasing part which substantially completely encloses an inner casing part which fixes the lock body in its longitudinal direction. The inner casing part carries a tubular projection which together with the cable portion passes through an aperture in an end wall of the outer casing part. The inner edge of the aperture is fitted by snap-action in an annular groove in the tubular projection. The synthetic plastics casing of the cable lock is mechanically rugged and its snap-action joint is visually unobtrusive.

Abstract: The cable lock comprises a flexible cable portion and an elongate lock body to which the cable portion is secured, oriented in the longitudinal direction of the lock body, by a first end and can be attached, oriented transversely to the longitudinal direction of the lock body, by a second end. A plastics housing, furnished with through openings for the ends of the cable portion, encases the lock body. The housing consists of two housing parts, pushed into each other in the longitudinal direction of the lock body and engaged with each other when pushed in, which housing parts are fixed by abutment surfaces against opposed abutment surfaces of the lock body. The one housing part forms a pocket, disposed laterally of the lock body, into which pocket a projection of the other housing part can be pushed.

Abstract: The electronic door lock for an electronic key provided with an electronic store for a key word datum has a latch bolt (5) actuatable at least from the inside of the door by means of a handle and a bolt (7) which is lockable and unlockable by an electric drive device (35). A control circuit (81) formed especially as micro-processor reads the key word datum stored in the key, through the reading device (77), and controls the electric drive (35) in dependence thereon. The reading device (77) includes sensor elements (93, 95), especially pieco-electric elements by way of which the drive direction of the electric drive (35) is selectable by a key movement of short stroke. In order that the electronic lock may be opened manually in case of emergency, a mechanical lock cylinder (113) is provided by means of which the bolt (7) is uncoupled from the drive connection to the electric drive (35) and is bringable into a drive connection to the handle nut (23) actuating the latch bolt (5 ).

Abstract: A swivel fitting for an outwardly opening window, with a device for moving the casement frame between the closed position and the open position, for example in the form of a hand crank, with position-fixing arm driven by the crank and with an operating handle on one frame member of the stationary frame, in order to fix the casement frame in the closed position. At least one locking plate is included on the casement frame which co-operates with a locking element on a drive rod operable by the handle. When the window is in the closed position, a locking projection of the locking plate protrudes into a groove in the stationary frame so that the closing movement of the window may be supported relatively early by actuation of the handle and to ensure high security against break-in.

Abstract: The invention provides a device for securing a window sash to the outer frame of the window so that, on the one hand the sash may be locked in a predetermined open position and on the other hand may be pivoted to open it fully. A single push-button serves both to disengage a catch in the predetermined open position and to release the sash for full opening.
