Abstract:
A key operated latch includes a housing which supports a lock plug, a motion control sleeve, and a sleeve-like cam therein. The cam rotates with the lock plug, while the motion control sleeve is stationary. The cam has at least one cam slot, and the motion control sleeve has at least one motion control slot. A shaft extends outward from the housing and has at least one projection which is engaged with both the cam slot and the motion control slot. The cam slot and the motion control slot are configured such that rotation of the lock plug imparts a sequence of rotational and axial movements to the shaft. A latching member attached to the shaft, moves between a latched position and an unlatched position in a sequence of axial and rotational motions in order to selectively secure a door, panel, or the like in the closed position. Also disclosed are additional embodiments that incorporate a wing knob or that have a lock plug sleeve and a motion control sleeve that are combined into a single part of one-piece construction. In one of the embodiments having a wing knob the wing knob freewheels without opening the latch when the lock plug is in the locked configuration.
Abstract:
The present invention is directed to a latching system that includes a latch assembly, a cup, and a keeper plate. The latch assembly includes a base, a lever, and a catch. The lever is pivotally connected to the base and the catch is pivotally connected to the lever. The base is pivotally attached to the cup such that it rotates about an axis of rotation that is perpendicular in direction in relation to the direction of the axis of rotation of the lever relative to the base. The keeper plate includes a keeper projection. The lever can be lifted and the latch assembly rotated about the axis of rotation of the base to clear the keeper from the catch and thereby allow the opening of a first closure member relative to a second closure member.
Abstract:
A keeper and a latch secures a first member such as a door panel against a second member such as a corresponding frame. The keeper is adapted for attachment to the second member and engages the latch in a fastened position.
Abstract:
A lever-action slam latch (10) includes a pair of opposing, nested slides (110, 150) so that a single latch can be mounted in either left-handed or right-handed door. The locking mechanism is difficult to circumvent, and permits the key to remain in the lock while the latch is opened.

A key operated latch includes a housing which supports a lock plug, a motion control sleeve, and a sleeve-like cam therein. The cam rotates with the lock plug, while the motion control sleeve is stationary. The cam has at least one cam slot, and the motion control sleeve has at least one motion control slot. A shaft extends outward from the housing and has at least one projection which is engaged with both the cam slot and the motion control slot. The cam slot and the motion control slot are configured such that rotation of the lock plug imparts a sequence of rotational and axial movements to the shaft. A latching member attached to the shaft, moves between a latched position and an unlatched position in a sequence of axial and rotational motions in order to selectively secure a door, panel, or the like in the closed position. Also disclosed are additional embodiments that incorporate a wing knob or that have a lock plug sleeve and a motion control sleeve that are combined into a single part of one-piece construction. In one of the embodiments having a wing knob the wing knob freewheels without opening the latch when the lock plug is in the locked configuration.
Abstract:
A multi-point latching system is adapted for mounting on a panel (202) and securing the panel (202) to a frame (200). The system includes a central latch (20), remote latches (108) and connecting rods (100, 102, 104). The central latch (20) includes a housing (26) and a handle assembly (22) pivotably mounted in the housing (26) for rotation about an axis parallel to the panel (202) for opening and closing the central latch (20). The handle assembly (22) extends through the housing (26) and includes a handle (24) and a pivot arm (38). The pivot arm (38) extends from the back of the housing (26). The central latch (20) also includes an actuator (64) pivotably mounted for rotation normal to the panel (202); and a link (62) connecting the handle assembly (22) to one of the connecting rods (100, 102, 104), which is also connected to the actuator (64), such that the actuator (64) is rotated by rotating the handle assembly (22). The remote latches (108) are engaged by rotation of the actuator plate (64) through the connecting rods (100, 102, 104).
Abstract:
A latch actuator in which a shaft 50 is connected to move a bolt has a bushing 9 having at least one projection or means for preventing insertion of an unauthorized tool. A key 80 has an outer formation such as key recess 86 which can mate such a projection to permit insertion. A cap subassembly 10 of the latch actuator is provided with projections 15 which are of a size and so positioned as to correspond with internal recesses 85 of the key so as to allow the cap subassembly to enter into the bore of the key. The projections 15 and recesses 85 are arranged about the circumference to embody a binary code with equal divisions of the circumference being either raised or recessed. The inserted key rotates the subassembly 10 which can either directly turn the shaft 50 or where a latch bolt mounts onto the shaft 50 can act via a guide pin and cam slot arrangement to both rotate and axially move the bolt. Because a cap portion 8 rotates freely on top of the cap subassembly 10 the arrangement makes it impossible, or at least very difficult, to rotate the shaft 50 by means of a tool which rotates the cap portion.

Pestillo (10) del tipo de cerradura de acción deslizante para la instalación en una abertura de un panel de puerta (250) para retener de forma que se pueda liberar el panel de la puerta con relación a un marco (252) caracterizado porque comprende: a) un cuerpo del pestillo (20) provisto de un par de aberturas opuestas (34, 36); b) un picaporte (70) giratoriamente montado en el cuerpo del pestillo (20), el picaporte (70) estando provisto de una primera superficie de leva (96) y una segunda superficie de leva (96), el picaporte (70) siendo giratorio entre una posición cerrada y una posición abierta; c) un primer resbalón deslizante (110) y un segundo resbalón deslizante (150), el primer resbalón deslizante (110) y el segundo resbalón deslizante (150) estando montados en el cuerpo del pestillo (20) para desplazarse a través de las aberturas opuestas (34, 36), el primer resbalón deslizante (110) estando provisto de una superficie de leva (148) para el acoplamiento con la primera superficie de leva (96) del picaporte (70), el segundo resbalón deslizante (150) estando provisto de una superficie de leva (184) para el acoplamiento con la segunda superficie de leva (98) del picaporte (70), el picaporte (70) y los dos resbalones deslizantes (110, 150) estando montados en el cuerpo del pestillo (20) de tal forma que el primer resbalón deslizante (110) es desplazado por leva hacia dentro mediante la primera superficie de leva (96) del picaporte (70) a través de una de las aberturas opuestas (34, 36) del cuerpo del pestillo (20) mientras que el segundo resbalón deslizante (150) es desplazado por leva mediante la segunda superficie de leva (96) del picaporte (70) hacia dentro a través de la otra de las aberturas opuestas (34, 36) en el cuerpo del pestillo (20), cuando se gira el picaporte (70) desde la posición cerrada a la posición abierta.
Abstract:
A keeper (12) and a latch (10) secures a first member such as a door panel(102) against a second member such as a corresponding frame (104). The keeper is adapted for attachment to the second member and engages the latch in a fastened position.
Abstract:
A latch has a bushing which has at least one bushing projection for preventing insertion of an unauthorized tool to rotate a latch actuator of the latch. Only a key having an outer key recess which can mate with bushing projection on the bushing permits insertion of the key. The cap subassembly of the latch is provided with projections which are of a size and so positioned as to correspond with the internal recesses of the key so as to allow the cap subassembly to enter into the bore of the key and permit a mating engagement of internal recesses on the key and projections on the cap subassembly. Because cap portion rotates freely on top of the cap subassembly which is the part of the cap driven by the key, the arrangement makes it impossible, or at least very difficult, to rotate the shaft and in turn the pawl with a tool which rotates the cap portion.
