Definitions

  • the invention relates to a self-locking rim lock and to a method for unlocking of a self-locking rim lock.
  • Self-locking rim locks are known, in particular for outside doors.
  • an auxihary bolt of a known self-locking rim lock is pressed in, for instance as a result of closure of a door on which the rim lock is mounted, a bolt of the rim lock automatically moves from a release position to a lock position, so that the door upon closure thereof can be automatically locked.
  • a known self-locking rim lock is provided with a turning knob for unlocking of the lock from an inside space. Upon unlocking, the mentioned bolt of the lock is moved from the lock position to the release position by turning the turning knob manually.
  • Such a known rim lock enables the lock to be simply and quickly unlocked from an inside space, which promotes ease of use. Moreover, the door concerned can thus offer a safe escape route.
  • a disadvantage of this known rim lock is that a malicious person can unlock the lock relatively easily from outside, for instance by operating the turning knob with a hook or the hke, for instance via a letterbox opening in the door.
  • a known alternative rim lock the turning knob can be blocked or uncoupled by means of a key. While this can counteract the just-described abuse from outside, such a design leads to disadvantages at the same time. For instance, with such a self-locking rim lock someone may easily get accidentally locked in if no fitting key is available in the inside space concerned. Even if the key is available, such a lock may make a quick escape, for instance in case of fire, more difficult: finding and manipulating the key takes time and may in case of panic be an irresponsibly complex procedure.
  • An object of the current invention is to provide a self-locking rim lock with which a better burglary protection and/or a safer escape route can be realized, whereby, in particular, at the same time a proper burglary protection and a safe escape route are enabled.
  • An object is to solve at least partly at least one of the above-described disadvantages of known self locking rim locks.
  • An object is to provide a self-locking rim lock that meets one or more relevant official standards or norms.
  • An object is to provide a user-friendlier self-locking rim lock.
  • a self-locking rim lock which comprises a lock housing, a bolt and a first operating element outside the lock housing.
  • the bolt has a lock position and a release position. In the lock position a door on which the rim lock is generally mounted is locked, and in the release position the door is not locked anymore.
  • the first operating element is operatively connected with the bolt for manual unlocking of the lock by a rotation of the first operating element with respect to the lock housing.
  • the rim lock is provided with a bolt blocking provision which is configured to keep the bolt in the release position.
  • the rim lock is provided with an auxiliary bolt which is configured for, upon pressing-in thereof, operating the bolt blocking provision to remove a blockade of a locking movement of the bolt from the release position to the lock position.
  • the first operating element comprises at least one second operating element which is manually movable from a blocking position to a release position.
  • an improved burglary protection can be reahzed, whereby in the blocking position the first operating element is more difficult to operate from outside by a mahcious person.
  • the lock can thus be unlocked from the inside relatively simply, safely and quickly, in particular without use of a key, for instance with a single continuous movement of the hand.
  • a safe escape route is provided at the same time.
  • the rim lock in particular a bolt operating mechanism thereof, is configured to be self-locking in a mechanical way, such that self-locking is substantially driven by spring tension stored in the rim lock, which spring tension, prior to self-locking, has been obtained from a manual operation of the rim lock.
  • Such mechanical self-locking is known per se for rim locks, and can be used with advantage in a rim lock according to the invention.
  • a method for unlocking of a herein described self-locking rim lock comprises manually moving the at least one second operating element from the blocking position to the release position and then rotating the first operating element with respect to the lock housing.
  • Fig. la shows an isometric view of an example of a self-locking rim lock with a second operating element in a release position
  • Fig. lb shows a partly cutaway front view of the rim lock in the position of Fig. la;
  • Fig. 2a shows a cross-sectional view along the line II -II in Fig. lb of the rim lock in the position of Figs la and lb;
  • Fig. 2b shows a cross-sectional view similar to Fig. 2a of the rim lock with the second operating element in a blocking position
  • Fig. 3a shows a partly cutaway isometric view of the rim lock in the position of Fig. 2b;

  • a self-locking rim lock 2 which comprises a lock housing 4, a bolt 6 and a first operating element 10, for example a turning knob 10, outside the lock housing 4.
  • the first operating element 10 is operatively connected with the bolt 6 for manual unlocking of the lock 2 by a rotation of the first operating element 10 with respect to the lock housing 4.
  • the bolt 6 is thereby brought from a lock position to a release position.
  • a door on which the rim lock 2 is mounted cannot be opened.
  • the release position the door can be opened, though it is not precluded that for this still an additional operation is necessary, such as bringing a second bolt or catch bolt in a release position.
  • the bolt of the rim lock can then be regarded as the dead bolt.
  • the bolt 6 has the function of both catch bolt and dead bolt.
  • the rim lock 2 comprises a bolt blocking provision, not shown in detail here, which is configured to keep the bolt 6 in the release position.
  • the rim lock 2 comprises an auxiliary bolt 18 (see Figs la, lb, 3a) which is configured for, upon being pressed in, operating the bolt blocking provision to remove a blockade of a locking movement of the bolt 6 from the release position to the lock position.
  • the rim lock 2 shown may thus be provided with an auxiliary bolt 18 which ensures that the bolt 6, upon closing of the door, locks automatically and so, from the release position, automatically moves to the lock position.
  • the movement of the bolt 6 from the lock position to the release position is hereinafter denoted by the term unlocking and the movement of the bolt 6 from the release position to the lock position is hereinafter denoted with the term locking.

  • Such a bolt operating mechanism for a rim lock is generally known per se in diverse variants and is therefore not shown in detail in the drawings.

  • a particularly sound rotation blocking can be provided, for example when, as shown, the at least two second operating elements 12, 12' are substantially uniformly distributed along a circumference around the operating rotation axis A. It will be clear that the invention is not limited to a plurality of second operating elements, nor to any maximum number of second operating elements.
  • rim lock 2 may analogously be implemented as a plurality, in particular elements that are configured to cooperate with the second operating elements 12, 12’.
