Abstract:
A bar lock preferably mounted in the edge lips of doors (12) of metal cabinets has a lock (16) provided with an actuating element that extends outwards through the door leaf (12), such as a handle, turning handle, key or the like, and at least one bar (18) made of a flat strip of material that extends in the corner space or the like parallel to the door edge and is mounted edgewise and retained at at least one spot on the door leaf (12), away from the lock, in a movable manner in the longitudinal direction by means of guiding elements with a corresponding cross section (20). At least one holding element (38) located on the door frame locks and receives the bar (18) in the closed position of the door. The holding element (38) is designed as a bracket with a U-shaped profile secured to the frame (24) by one leg of the U-profile so that the profile of the bar extends between the legs of the U-profile of the bracket. The legs of the U-profile of the bracket are provided with notches open in one of the axial directions of the spindle (18) for receiving and locking the locking pins (40) carried on the bar (18).
Abstract:
A cremone bolt operator is provided which includes a small and a large pinion gear, each having gear teeth and a central aperture, a first and a second rack gear, each having a first and a second set of parallel teeth, the rack gears in opposed relation to one another wherein the first and second sets of teeth are in facing relation. The first set of teeth on each of the rack gears is in meshed engagement with the small pinion gear and the second set of teeth on each of the rack gears is in meshed engagement with large pinion gear. A spindle is sized to fit in each of the central apertures of the small and large pinion gears. A locking device that causes the spindle to selectively engage either the small pinion gear or the large pinion gear.

Abstract:
The lock comprises four removable bolts (1) screwed onto a bolt tail (2) obtained from a tubular profiled section (3). The bolts comprise an internal fixing screw (4) arranged inside a bush (10), the screw bearing on the bush in order to block it in position. The screw and the bolt bush are separable.
Abstract:
A door locking device for a door cooperating with a door frame includes a cylinder lock, at least one elongated bolt, and an emergency unlocking mechanism. The elongated bolt is adapted to move linearly to engage to and disengage from the door frame. A transmission including an operating wheel translates circular motion of a rotor of the cylinder lock to a linear motion of the elongated bolt. The emergency unlocking mechanism includes a gear arm connected to a handle and adapted to turn the operating wheel when the handle is turned, disengaging the elongated bolt from the door frame.
Abstract:
A latching mechanism (2) can be used to attach a child's seat to various supports to make a high chair, stroller, bicycle with child seat, etc. The mechanism is attached to the seat frame with the elongate element (30) connected to the seat back and the balance of the device shown connected under the seat proper. The pins (8a, b) are biased (by action of spring 14) into holes of a respective support so as to join the seat thereto. The pins are disengaged by linear motion of rod (16) which is converted to simultaneous linear movements of rods (18) due to notches on the rods engaging with the teeth of twin gears (24a, b). The sprung catch (28) can prevent movement of rod (16), and thus prevent removal of the seat, in that the apertured plate (32) hinders movement of tab (42) of rod (16).
Abstract:
The invention relates to a bar lock for a locking system that is used, in particular, in metal cabinet doors. Said locking system comprises a lock body (10) and a pinion (18), which is mounted therein and which is provided for actuating the lock bars (12) reaching through the lock body (10). The invention is characterized in that two pinions (18), which are connected to one another with positive fit, are placed inside the one-piece lock body (10), and the engaging openings, which are formed on the lock bars (12) and provided for the teeth (19) of the pinion (18), are provided in the form of laterally open denticulations (29) and as perforations (30).
Abstract:
The invention concerns a rod-type closure preferably for locking switch cupboard or similar doors or hinged lids. The rod-type closure comprises a flat strip rod (18) which is disposed such that it extends parallel to the edge of the door, preferably in the canting space (10), and has at least one locking part (34) disposed thereon. The rod-type closure also has a closure element (32), disposed on the door frame (24), for accommodating the locking part (34) such that it is locked. The rod-type closure further comprises an actuating device (14) for the longitudinal displacement of the flat strip rod (18) between an opening and a locking position. According to the invention, in order to form the locking part (34), the flat strip rod (18) is offset out of its longitudinal plane over at least part of its longitudinal extension and the profile of the flat strip rod (18) forms with one of its narrow edges, in or adjacent the offset portion, the locking surface over which engages a hook part (36) of the closure element (32), said hook part being disposed parallel to the plane of the flat strip rod.
Abstract:
A multi-controlled security lock is described which is characterized in that it comprises in combination: a slide (18) which can be moved back and forth with respect to the frame (10) by at least one of two control devices i.e. a key control device (38) or a remote electric control device (40); a carriage (14) constrained by lock bolts (16, 16') and movable back and forth with respect to the frame (10); and a non-reversible actuating device (28, 30, 32, 34, 36) located between said slide (18) and said carriage (14), the arrangement being such that the back and forth movement of the slide causes, through said non-reversible device, the back and forth movement of said carriage, however, a force exerted on said carriage, at least in the lock opening direction, causes the carriage to be locked in position. A panic device (42) driving said slide (18) is also provided.
