  • profile 103 contacts foot 86 thereby rotating latch control toggle 80 to a second position against the restorative force of spring biased pin 69.
  • hold back member 120 Another aspect of this embodiment provided by the hold back member 120 can be explained in reference to Figure 21.
  • rotation of actuator 18 in the direction of arrow "A” causes lobe 19 to move hold back member 120 from the position shown in Figure 18(a) to the position shown in Figure 18(b).
  • Ridge 129 therefore engages the lip of catch 89 on latch control toggle 80.
  • This engagement retains spring latch assembly 50 in the retracted position against the forces of return springs 112 and 113. Therefore spring latch bolt 54 is in the retracted position and auxiliary bolt 94 is withdrawn thereby leaving the associated door in an unlocked state.
  • actuator 18 when actuator 18 is rotated in a direction opposite arrow "A", lobe 19 attacks ridge 122 to move hold back member 120 from the position shown in Figure 18(b) to the position shown in Figure 18(a).
  • spring latch assembly 50 when spring latch assembly 50 is in the extended position (regardless of the state of the dead latch assembly), rotation of actuator 18 in a direction opposite arrow "A” will cause lobe 19 to attack head 87 of latch control toggle 80 thereby driving the spring latch assembly from the extended position to the retracted position.
  • actuator 18 rotates between a retain position (placing the hold back member in the engage state) and a release position (to disengage the hold back member) through an intermediate position.
  • actuator 18 moves the spring latch bolt from the extended position to the retracted position.
  • FIG. 22 A representative positional adjuster 140 is depicted in Figures 22 and 23.
  • positional adjuster includes an L-shaped mounting plate 141 and a U-shaped bracket 142 that may be mounted to spacer plate 23 by means of a screw 143 extending through holes 144 and 145 to threadably engage threaded opening 39 in spacer plate 23.
  • a threaded plug 146 may be mated with threaded opening 147 in bracket 142.
  • plug 146 has a hex bore 148. Opening 149 in bracket 141 allows the installer to adjust the effective length "I" of plug 146. Therefore, with reference again to Figures 1(a) and 1(b) the locking mechanism may accommodate differently dimensioned lock stiles.
  • yet another aspect of this embodiment is the ability to interchange spring latch bolts for different handedness of a door. Since spring latch bolt 54 is releasably mounted on spring bolt carrier 52, it is a simple matter to change out one spring latch bolt for another. To this end, access opening 32 is located so that the installer can slightly depress the spring latch bolt thereby registering the head of screw 73 with access opening 32. The installer can then remove screw 73 to detach the spring latch bolt 54 and reverse its attach direction.
  • casing 220 is provided to accommodate a deeper set back for a lock cylinder.
  • Casing 220 has side plate 22 and a front plate 24 that are the same as described above.
  • spacer plate 223, as is shown in Figure 25 is of a greater length to hold front plate 24 forwardly of side plates 22 and, correspondingly place the centerline of the lock cylinder a farther distance back of the nose of the door. Since the components of the locking mechanism assume the same mounting orientation relative to side plates 22, it is necessary in this embodiment to provide a longer dimension to spring latch bolt 254 with hardened pins 249, as is illustrated in Figure 26.
  • casing 320 again includes side plates 22
  • additional side extension plates 321 are located forwardly of side plates 22.
  • a plurality of longer dimensioned spacer plates 323 are the used to secure side plates 22, side extension plates 321 and front plate 24 together.
  • a still longer spring latch bolt 354 with hardened pins 349 and a longer auxiliary bolt 394 are used to match the depth added by the side extension plates 321 in order to accomplish the deeper set back.

Abstract

Cette invention concerne un mécanisme de verrouillage comprenant un boîtier abritant un ensemble loquet à ressort. Un élément de retenue commandé par actionneur, disposé coulissant dans le boîtier, retient le pêne du loquet à ressort en position de rappel ou bien autorise un mouvement de va-et-vient libre dudit pêne. Un ensemble pêne à cran d'arrêt comporte un pêne auxiliaire dont la partie d'extrémité libre en forme de tige dépasse de la partie avant du boîtier. Cette extrémité libre peut être de forme cylindrique et se terminer en arrondi. Dans les modes de réalisation exposés, le pêne du loquet à ressort est déposable et réversible sur son support, avec choix de différents points de consigne. De même, le pêne auxiliaire peut être changé sélectivement. Il existe des dispositifs de réglage de position pour le réglage de consigne ainsi que des dispositifs de réglage de chanfrein entre la plaque avant et la plaque couvercle du boîtier.
