Definitions

  • the presently disclosed subject matter relates in general to the field of locking systems, and in particular to devices for controlling operation of locking bolts of the locking systems.
  • Locking systems for doors, windows, gates, and other barriers are well known in the art.
  • One such known locking system to lock a door uses a locking bolt slidably mounted on the door. To lock the door, the sliding bolt slides toward the door's frame and partially penetrates an opening in the door frame or instead an appropriately- positioned bounded area of a brace mounted on the door frame. To unlock the door, the sliding bolt slides in the opposite direction, to disengage the door frame or the brace.
  • This locking system may also be used to lock a window in an analogous fashion. According to different needs of users, it is sometimes needed to restrict the movement of the locking bolt along its path between its unlocked position and locked position.
  • GB 2195695 discloses a lockable sliding bolt that comprises: a spigot housed in a bolt housing and adapted to move relative to the housing between an extended position and a retracted position; retaining means in the form of cam having a releasable operative mode in which it serves to retain the spigot in the extended position; and a key-operated lock operatively connected to the cam to lock the cam in its operative mode.
  • GB 1379613 discloses a lock that comprises a housing mountable on a surface, a socket separate from the housing, a bolt slidably mounted in the housing; an elongated projection integral with the bolt projecting transversely of the bolt and beyond the housing for manual operation of the bolt the housing being provided with holes for fixing screws which are accessible only after the bolt has been removed; and a plurality of locking members each of which is independently movable at least in one position of the bolt between a respective first position or a respective first selected position at which each locking member is operable to lock the bolt and a respective second position at which it is inoperable to lock the bolt.
  • a restricting device of a locking system for restricting movement of a locking bolt along a main axis of the device comprising:
  • a restricting member comprising a passage extending along a passage axis and formed with at least one open end, and a restricting portion disposed outside said passage, the restricting member being rotatable about a rotation axis between an unrestricting position, in which said passage axis is collinear with the main axis for receiving therein a portion of said locking bolt, and a restricting position, in which the passage axis intersects with the main axis thereby preventing said portion said locking bolt from being received in said passage upon engagement of the locking bolt with the restricting portion;
  • a manipulator configured for selectively rotating said restricting member between its unrestricting position and its restricting position
  • said restricting member further comprises two support portions coaxially disposed at opposite sides of the restricting member and defining said rotation axis, and said support portions are configured for supporting said restricting member when said restricting device is mounted within the locking system.
  • a locking system comprising:
  • a second side wall having a second opening; a locking bolt displaceable along a path extending through said first opening and said second opening between a first extreme position in which said first side wall and said second side wall are free to be displaced with respect to each other and a second extreme position in which said first side wall and said second side wall are arrested with respect to each other; and

  • the locking bolt 104 is forced against the biasing force of the spring 150 along the main axis Y' toward the brace 106 while being rotated. This brings the locking bolt 104 to its transition position, shown in Fig. 6B. Further rotation of the locking bolt 104 causes the projection 108 to be aligned with the passage of the barrier 111, and backward movement of the locking bolt 104 upon the pushing force of the spring, causes the projection to be introduced into the barrier 111 and to be constrained therein.
  • the locking bolt 104 In order to displace the locking bolt 104 from its locked position to its unlocked position, the locking bolt 104 is forced against the biasing force of the spring 150 along the main axis Y' toward the brace 106, so that the projection 108 escapes the barrier 111, while the locking bolt 104 is being brought to its transition position. By further rotation of the locking bolt 104 and movement of the locking bolt 104 to a direction opposite to the first flange 107a, the locking bolt reverts to its unlocked position.
  • the locking bolt 104 does not extend from the first opening 109.
  • the first opening 109 is free to be displaced with respect to the second opening 106b, e.g., when the door to which the sliding bolt latch 102 is opened by a user with respect to a frame, to which the brace 106 is mounted.

Abstract

L'invention concerne un dispositif de restriction pour restreindre le mouvement d'un pêne d'un système de verrouillage le long d'un axe principal du dispositif, le dispositif de restriction comprenant : un élément de restriction comprenant un passage s'étendant le long d'un axe de passage et comporant au moins une extrémité ouverte, et une partie de restriction disposée à l'extérieur dudit passage, l'élément de restriction pouvant tourner autour d'un axe de rotation entre une position de non-restriction, dans laquelle ledit axe de passage est colinéaire avec l'axe principal pour y recevoir une partie dudit pêne, et une position de restriction, dans laquelle l'axe de passage coupe l'axe principal, empêchant ainsi ladite partie dudit pêne d'être reçue dans ledit passage lors de l'engagement du pêne avec la partie de restriction; et un manipulateur configuré pour faire tourner sélectivement ledit élément de restriction entre sa position de non-restriction et sa position de restriction; ledit élément de restriction comprend en outre deux parties de support disposées coaxialement au niveau des côtés opposés de l'élément de restriction et définissant ledit axe de rotation, et lesdites parties de support étant configurées pour supporter ledit élément de restriction lorsque ledit dispositif de restriction est monté à l'intérieur du système de verrouillage.
