Definitions

  • a remote latching mechanism is a latching mechanism in which the latching action of the mecha ⁇ nism occurs at a location remote from the latch actuator part of the mechanism.
  • Many types of remote latching mechanisms are known and used in the art.
  • a centrally located latch actuator assembly which usually consists of a handle protruding from the outside of the door and connected by an axle to the mechanism on the inside of the door, is connected in an offset fashion to one end of a pair of latching bars with each bar traversing the inside of the garage door horizontally and in opposite directions.
  • the other end of each of the latching bars terminates just short of the inside edge of the respective sides of the garage door, where it is usu ⁇ ally retained in a keeper, when the latching mechanism is in an open position.
  • the present invention is directed towards a remote latching mechanism which provides a high degree of precision and security, whether used as a compres- 0 sion type remote latching mechanism or, alternatively, used as a non-compression type remote latching system.
  • the remote latching mechanism is particularly suited for use in securing closure members to a frame, such as cabinets or like structures.
  • the present invention comprises an actuator assembly or a handle assembly, with a connecting means, preferably a bar or rod, connected to at least one latch assembly.
  • the handle assembly comprises essentially a cup adapted to be 0 affixed within an aperture in a door or the like and a handle pivotally mounted to the cup for actuation from the outside of the door.
  • the connecting means is preferably a continuous longitudinal rod which is dis ⁇ posed vertically on the inside of the door and is 5 affixed to the handle for rotational movement in response to the pivoting movement of the handle.
  • actuating assem ⁇ bly comprises a cup 0 adapted to be affixed within an aperture in a door or the like by means of a spring clip or by means of a bracket and screws. Disposed within the cup for rotational movement is an actuator hub which is affixed to the connecting means, whereby upon applica-
  • the actuating assembly comprises a lever affixed to a terminal end of the • connecting means on the outside of the cabinet.
  • Pivoting the lever transmits rotational movement to the connecting rod, which in turn actuates the latch assembly.
  • the latch assembly comprises a housing adapted to be affixed to the inside of the door, a crank, a pair of link members connected to the crank, a pawl support member connected to the links, and a pawl affixed to the support member.
  • the crank is in operable engagement with the connecting rod, whereby upon rotation of the rod, the pawl is pivoted and slid between latched and unlatched positions.
  • the link members, forming the operative connection between the crank and the pawl, comprise over-center members to provide positive latching action. It is a feature of the present invention that the actuator assembly actuates the latch assembly through the rotation of the connecting means about its longitudinal axis.
  • this feature allows for the use of a continuous rod as the connecting means for a plurality of latch assemblies operable by actuation of a single actuator assembly. It should be noted, however, that a non-continuous rod or other type of connecting means rather than a con ⁇ tinuous connecting means could be used without departing from the scope of the present invention. Accordingly, it is an object of the present invention to provide a remote latching mechanism that can be used as either a compression or non-compression remote latching mechanism. It is a further object of the present invention to provide a remote latch mechanism wherein the latch assembly is actuated through an elongate connecting means which rotates about its longitudinal axis.

Abstract

Un mécanisme de verrouillage à distance comprend un organe de liaison, de préférence une barre cylindrique (50), un ensemble d'actionnement (20) qui met l'organe de liaison en rotation autour de son axe longitudinal, et un ensemble de verrouillage (60) relié à l'organe de liaison (50) de façon à se déplacer entre des positions de verrouillage et de déverrouillage lorsque l'organe de liaison (50) est mis en rotation. L'ensemble de verrouillage (60) comprend une manivelle (72), au moins un lien (80) à détente brusque, un support de cliquet (86) et un cliquet (94), tous ces éléments étant interconnectés de sorte que lorsque la manivelle (72) est mise en rotation, le cliquet (94) pivote et glisse par rapport au boîtier d'un verrou (62) entre des positions de verrouillage et de déverrouillage. L'ensemble d'actionnement (20) comprend un organe d'actionnement fixé à l'organe de liaison (50). Dans un mode de réalisation, l'organe d'actionnement comprend une poignée pivotable (32). Dans d'autres modes de réalisation, l'organe d'actionnement comprend un organe essentiellement cylindrique (52, 232, 260, 452) sur lequel on applique un couple au moyen d'un outil (270) ou d'un levier (400) de façon à mettre en rotation l'organe de liaison.
