Definitions

  • the invention is based on an automatically locking lock, in particular a door lock according to the type of the main claim.
  • Locks of this type work together with a locking plate having corresponding recesses and are provided with a resetting device which acts on the latch in the closing direction.
  • the latch which is provided with a beveled surface in the direction of addition, is pushed through the lock plate into the lock housing against the force of the restoring device.
  • the recesses in the castle . Covering the tulp and in the striking plate, the latch moves back out of the lock housing and into the striking plate due to the restoring force.
  • the locking effect provided by the latch is not sufficient to secure against unauthorized opening of the lock.
  • the automatically locking lock according to the invention with the characterizing features of the main claim has the advantage that no additional bolt is required, that a conventional locking plate can be used and that no changes need to be made in the frame, for example because of a further extending case.
  • the locking bolt automatically extends into its locking division when the lock moves into the locking plate, the same protection is provided against pushing open the door as in the case of a lock locked by an arbitrarily operated locking bolt.
  • the automatic locking according to the invention does not result in any disadvantages with regard to the normal operation of the lock. It can be used for locks with axially slidable locking bolts as well for locks with a rotatably mounted locking bolt, a so-called swivel bolt that moves into the locking plate by rotating it by 45 °.
  • a trigger mechanism for triggering the automatic opening of the locking bolt is provided, which can be actuated by the latch. This eliminates the need for an additional trap with all associated devices such as springs, recesses, etc.
  • the trigger mechanism can be triggered when the latch is extended into the striking plate. This has the advantage that it is impossible for the locking bolt to be extended prematurely into the striking plate, that is to say before the lock has completely run into the striking plate. Adjustment of the lock after installation of the lock in., The door is therefore omitted.
  • the locking bolt is loaded in the closing direction by a reset element and can be locked in its releasable position in the lock.
  • a reset element In this way, a purely mechanical and thus inexpensive manufacture and retraction of the locking bolt is ensured, the locking of the locking bolt in its locked position preventing the locking bolt from moving out again immediately after the door is opened.
  • the locking bolt can be automatically retracted when the lever follower is turned in the opening direction.
  • the latch is used to open the door in the lock by means of the door handle or rotary knob provided on one side of the door.
  • a doorknob or a rotary knob is provided on the inside of the door, while only a fixed button or a handle is provided on the outside of the door. Due to the design according to the invention, the door can be opened from the inside by simply actuating the door handle or the rotary knob, despite the automatically locking lock, which is absolutely necessary, for example, in the case of escape doors.
  • the lever follower has an extension which actuates a lever device acting on the locking bolt which moves the locking bolt into its retracted position when the lever follower is rotated in the opening direction.
  • the closing bolt can also be retracted purely mechanically and therefore inexpensively by turning the lever foot.
  • the end of lever devices is common in locks, so that there are no constructive problems.
  • the locking bolt has a recess into which a latching element for locking the locking bolt can be locked in its retracted position.
  • an axially displaceably guided latching rod can be latched into the recess provided in the locking bolt and the rod is loaded in the latching direction by a reset element, the latching rod at its end facing away from the recess in the locking bolt is mounted in a path provided on the latch, through which the latching rod can be pulled out of the recess provided in the locking bolt against the force of the reset element when the latch is extended.
  • the path provided on the latch shifts relative to the locking rod guided axially in the SchloQ.
  • the track is shaped in such a way that the latching rod is lifted out of the recess when the latch is extended and, conversely, can snap into the recess when the latch is retracted.
  • the end of the locking rod facing the hall has a rotatably articulated hook arm and a mechanical rocker is provided into which the hook can be hooked, with a lever arm which is rotatably mounted in the housing and whose free end has a roller with which the narrow side of the latch facing away from the locking bolt and having a corresponding profile cooperates as a rocker.
  • the roller rolls in and out of the trap on the narrow side of the trap, the profile being designed such that the hooked-in locking bar is raised when the trap is extended and releases the locking bolt when a certain lifting height is reached.
  • the latching rod can be hooked into the mechanical rocker with its hook arm when the latch is inserted into the lock. This ensures that the release mechanism for the locking bolt is armed by the entry of the lock into the striking plate.
  • the hook arm of the latching rod can be automatically released from the rocker when the latch follower is actuated. This ensures that when the door is opened with the help of the doorknob when the doorknob is released and the case thus extended, the locking bolt does not extend, since the latching rod is unhooked from the rocker and is therefore not lifted out of the recess in the locking bolt. The next time the door is closed, the lock can run back into the striking plate and the lock can be released.
  • a push rod is arranged on the handle follower which, when the handle follower is turned in the closing direction, unlatches the hook arm of the latching rod from the rocker.
  • the hook arm of the latching rod can be unhooked from the rocker by means of a locking cylinder when the hall is actuated. This prevents the locking bolt from moving out again immediately after opening and preventing the lock from entering the locking plate again.
  • the profile of the narrow side of the latch facing away from the locking bolt has the shape of a jag, the flank of which faces the lock cuff is pulled lower than the flank pointing in the opposite direction.
  • the end face of the hook arm of the latching rods is chamfered.
  • tumblers which are displaceably guided in the housing between two positions are provided in the area of the locking bolt and prevent the locking bolt from being retracted in one position while releasing the locking bolt in the other position.
  • Such tumblers are known per se. They serve to prevent the extended locking bolt from being pressed back into the lock from outside by forceful intervention.
  • the tumblers block the end pin fixed to the locking bolt from moving back into the lock.
  • the tumblers are moved into their release position by the driver stit t arranged on the lock cylinder. Since the locking bolt can usually be closed twice, at least two independent tumblers are also provided.
  • the tumblers in the direction of their closed position are each relieved by a reset device. This ensures that the tumblers automatically move into their closed position when the locking bolt is extended.
  • the handle follower engages a lever which is mounted in the housing and which, when the printer nut is turned in the opening direction, holds the tumblers in their position releasing the return of the locking bolt.
  • FIG. 2 shows a lock according to FIG. 1, which was opened by actuating the printer, with an engaged, activated locking bolt and a retracting latch
  • FIG. 3 shows a lock according to FIG. 1, which was opened by actuating the locking cylinder, with the locking bolt retracted, activated and the latch and extension extended
  • Fig. 4 shows a lock according to Fig. 1 with a retracted, armed lock bolt and retracted by running into the striking plate.
  • the lock shown in FIG. 1 has a latch 2 guided axially in a housing 1 and a locking bolt 3 likewise axially guided in the housing 1, both of which are each removed from the housing 1 by a recess in a lock faceplate 4 arranged on the end face of the housing 1 are extendable.
