Definitions

  • the invention relates to a locking device with the features of the preamble of claim 1.
  • Locking devices of the type mentioned are known from the prior art, for example EP 3 372 757 A1 . It describes a locking unit which has a central lock and several additional locks.
  • the additional locks each have a latch bolt and a swivel bolt, which, when locked, move into the locking position with a time delay.
  • the latch bolt blocks the lock chain before it is released and extended to lock.
  • the Swing bolt is positively coupled to the lock chain via gearwheel sections, so that the swivel bolt is driven when the lock chain is shifted.
  • the swing bolt is then pivoted when the latch bolt has reached a certain extended position and released the lock chain.
  • the lock chain is coupled with components of the lock mechanism in the lock and a connecting rod that connects the additional lock with the central lock.
  • This locking unit enables the latch bolt and swivel bolt to be locked at different times.
  • the latch bolt must first block the lock chain so that the door can be brought into the closed position, but then release the lock chain in good time. After releasing the lock chain, it must then be moved together with components of the lock mechanism and the connecting rod in order to bring the swivel bolt into the closed position.
  • the additional lock consists of a large number of individual components, so that production and assembly are comparatively complex.
  • the invention is based on the object of enabling reliable locking in a locking device with simple structural means.
  • the invention solves this problem by the features of claim 1.
  • the Locking device in that the swivel bolt as a swivel bolt drive has a spring (e.g.
  • a tension spring acting on the swivel bolt, by means of which the swivel bolt is pretensioned in a position pivoted into the secondary lock (for pivoting out), the swivel bolt being coupled to the latch bolt in this way that when the latch bolt, for example as a result of the triggering of a trigger element, reaches a partially extended limit position when extending from the secondary lock, triggered or released and driven by the spring is pivoted into a position swiveled out of the secondary lock, the Swivel bolt is decoupled from the connecting rod when pivoting out.
  • the swivel bolt is in particular also decoupled from the drive rod before it is swiveled out, ie in the swiveled-in position.
  • the swivel bolt can be swung out suddenly, since only the swivel bolt needs to be accelerated (low inertia).
  • the drive of the swivel bolt (spring) acts directly on the swivel bolt, so that a swivel movement of the swivel bolt is not influenced by other components of the secondary lock or a connecting rod.
  • the swivel bolt has its own drive (swivel bolt drive).
  • the swivel bolt is also locked quickly and reliably if, for example, there is impairment due to increased friction on the drive rod (decoupling of the swivel lock).
  • the swing bolt's own drive means that it is pivoted out or locked independently of other components of the secondary lock. This increases security, since the swivel bolt, for example, still reliably moves into the closed position if, for example, the latch bolt is impaired or tampered with.
  • the locking device can have a main lock and at least one secondary lock.
  • Main lock and secondary lock can be attached to a faceplate.
  • the main lock and the secondary lock are spaced apart from one another along the faceplate, for example by at least 20 centimeters (spatially separated locking points).
  • the main lock and the secondary lock are coupled to one another by means of a connecting rod.
  • the main lock can serve to actuate the locking device, for example by means of a door handle and / or a lock cylinder.
  • a motor drive can be provided to drive the drive rod.
  • the main lock can optionally have a latch and / or a bolt.
  • locking can in particular take place automatically, so that the latch bolt and swivel bolt of the secondary lock are automatically brought into the locking position shortly before or when the window or door is in a closed position (self-locking). Unlocking can be done manually by operating the main lock.
  • the swivel bolt of the secondary lock is mounted on the secondary lock or its housing so that it can pivot about an axis (swivel bolt axis).
  • the swivel bolt can be swiveled between a swiveled-in position (unlocking position) and a swiveled-out position (locking position) in relation to the secondary lock.
  • a spring e.g. tension spring acts on the swivel bolt, by means of which the swivel bolt swings out in the outward direction, i.e. is biased to pivot out.
  • the tension spring can, for example, be designed as a helical spring.
  • the latch bolt is displaceably mounted on the secondary lock or its housing and can be retracted and extended relative to this (translational movement along the central longitudinal direction of the latch bolt).
  • the latch bolt has a latch head (free end, possibly protruding from the secondary lock) and a latch tail (rear end, always located in the secondary lock).
  • the latch bolt is biased in particular in the extension direction by means of a spring, for example by means of a torsion spring or a leg spring.
  • the latch bolt has a latch bevel on the latch head.
  • the latch bolt can be moved between a retracted or retracted position (unlocking position) with respect to the secondary lock and a fully extended position (locking position).
  • the latch bolt can also assume intermediate positions that are located between the unlocked position and the locked position.
  • the secondary lock can assume a total of several different positions (states), namely an unlocked position, a neutral position, a limit position and a locked position.
  • the swivel bolt and the latch bolt are completely swiveled or retracted into the secondary lock.
  • the locking device is thus completely unlocked, so that the door or the window on which the locking device is mounted can be opened.
  • the unlocked position can be achieved, for example, by actuating the handle or key actuation of the main lock, whereby the drive rod is driven and swing bolts and latch bolts are unlocked, i.e. be swiveled in or retracted. It is also conceivable that the drive rod is driven by a motor drive, thereby unlocking the swivel bolt and the latch bolt ("automatic opener").
  • the swivel bolt In the neutral position, the swivel bolt is in the position swiveled into the secondary lock and the latch bolt is in a neutral position, ie a (first) position extended out of the secondary lock (latch bevel protrudes from the secondary lock).
  • the position of the latch bolt corresponds to the position of a conventional (unactuated) door latch.
  • the neutral position is usually achieved when the main lock (door handle or lock cylinder) is not activated.
  • the (not yet locked or not yet back-pressure-secured) latch bolts Shortly before the door or window reaches the closed position, the (not yet locked or not yet back-pressure-secured) latch bolts are inserted starting from the neutral position by approaching the latch bevel on the frame or the strike plate so that the door or window can be brought into the closed position (door or window is then completely in the frame).
  • the latch bolt In the limit position, the latch bolt is in a (second) position partially extended from the secondary lock (limit position) and the swivel bolt is still in the position swiveled into the auxiliary lock (swivel bolt not yet triggered or released).
  • the limit position is reached after the door or window is in the closed position in the frame and the latch bolt moves out of the secondary lock again (into an opening for the latch bolt formed on the frame, for example).
  • the latch bolt In the limit position, the latch bolt is in a position that is further extended from the secondary lock compared to the neutral position (second, partially extended position). For example, the release element was previously actuated through contact with the frame, so that the latch bolt can be extended further out of the secondary lock than in the neutral position.
  • the locked position In the locked position, the swivel bolt and the latch bolt are completely swung out or extended from the secondary lock.
  • the locking device is thus locked so that the door or the window on which the locking device is mounted does not open can be. If the latch bolt and / or the swivel bolt are pretensioned in the pivoting direction or extension direction, the locked position is automatically reached with the door or window in the closed position (self-locking of the locking device).
  • the swivel bolt can advantageously be decoupled from the latch bolt when it is pivoted out.
  • the swivel bolt is in particular also prior to pivoting out, i.e. decoupled from the latch bolt in the pivoted position.
  • the swing bolt and latch bolt move or lock independently of one another. This contributes to a higher level of security.
  • the swivel bolt can be coupled to the latch bolt by means of a two-armed release lever, a first arm of the release lever being actuatable by the latch bolt and a second arm of the release lever actuating the swivel bolt, i.e. locking or releasing depending on the actuation by the latch bolt .
  • the release lever can be designed to be pretensioned against the swivel bolt (spring).
  • a spring can be provided, for example a tension spring. The spring can be coupled to the release lever at one end and to the secondary lock or its housing at the other end.
  • the swivel bolt can expediently have a recess into which the release lever engages with the second arm when the swivel bolt is in the position swiveled into the secondary lock. This creates a structurally simple and reliable locking state.
  • the recess can be formed on the side of the swivel bolt facing away from the swivel axis, i. E. on the radially outer narrow side of the swivel bolt.
  • the swivel bolt can have a coupling lever which is pivotably mounted on the swivel bolt and by means of which the swivel bolt is coupled to the spring.
  • a rotational movement of the swivel lock can be converted into an essentially translational movement at the free end of the coupling lever.
  • the coupling lever can have a bearing point (pivot axis) at one end for connection to the pivot bolt and at the other end a connection point for a spring, for example a pin section for a spring eye.
  • the swivel bolt can have a groove on a side of the swivel bolt facing away from the swivel axis of the swivel bolt (radially outer narrow side of the swivel bolt), into which the coupling lever at least partially penetrates when the swivel bolt is pivoted into the secondary lock.
  • This can A reduced space requirement in the secondary lock can be achieved, since the coupling lever is partially arranged in the swivel bolt in the swiveled-in position of the swivel bolt.
  • the groove on the side of the swivel lock facing away from the swivel axis can extend as far as the recess for the second arm of the release lever.
  • the pivoting movement of the release lever which is required, for example, for release can be reduced.
  • the second arm of the release lever reliably disengages from the recess when the swivel lock is released or released.
  • the second arm of the release lever can optionally run in the groove and thus support guiding of the swivel bolt if necessary.
  • the coupling lever is - based on the pivot axis of the swivel bolt - at the same height as the second arm of the release lever.
  • a locking lever can be provided for the swivel bolt, the locking lever being pretensioned against the swivel bolt and, in the position of the locking lever pivoted out relative to the secondary lock, engages or is aligned with a portion of the locking lever so that the The swing bolt is locked against swinging back into the secondary lock (anti-swing back lock).
  • a structurally simple locking element is thus created which prevents the swivel bolt from being swiveled back in an undesired manner, for example through manipulation.
  • the locking lever can be pivotably mounted on the secondary lock or its housing. The locking lever is arranged in particular on the side of the swivel bolt facing away from the swivel axis.
  • the locking lever can be arranged adjacent to the swivel bolt or, for example, as a result of the pretensioning, rest on the swivel bolt.
  • the locking lever can be pretensioned by means of a spring, for example by means of a tension spring.
  • the locking lever can have a groove on the side facing the latch bolt, into which the coupling lever can partially penetrate when the swivel bolt is pivoted in. This reduces the space required in the secondary lock.
  • a locking lever can be provided for the latch bolt, the locking lever being pretensioned against the latch bolt and, when the latch bolt is in the extended position with respect to the secondary lock, engages behind the latch bolt so that the latch bolt is locked against being pushed into the secondary lock (backpressure protection).
  • a locking element is provided which prevents undesired pushing back of the latch bolt, for example through manipulation.
  • the locking lever is preferably pretensioned against the latch bolt by means of a spring, in particular by means of a torsion spring ("locking spring").
  • the secondary lock can have a link coupled to the drive rod, the link being coupled to the latch bolt and the swivel bolt in such a way that the latch bolt is in the secondary lock can be pushed in and the swivel bolt can be pushed into the secondary lock.
  • the secondary lock can be brought into the unlocked position by simply actuating an operating element (gate).
  • the locking levers for the swivel bolt and the latch bolt can also be actuated (directly or indirectly) by the gate.
  • the link is only required for the unlocking process and can otherwise be decoupled from the latch bolt, the swivel bolt and / or the locking levers.
  • the link can have a guide nose facing the swivel bolt, which can be brought into engagement or engages with a guide surface formed in the swivel bolt in order to pivot the swivel bolt into the secondary lock.

  • the locking device 10 can have been unlocked beforehand by actuating the main lock 12, for example by actuating the lock socket 18 by means of a door handle (not shown) or by actuating the lock cylinder 20 with a key.
  • the latch bevel 31 comes into contact with the frame or a strike plate.
  • the latch bolt 30 is largely or completely pushed into the secondary lock 14. This displacement takes place against the force of the spring 54, the latch lever 50 also being pivoted.
  • the latch bolt 30 As soon as the latch bolt 30 begins to align with the latch opening on the frame side, the latch bolt 30 is pushed out of the secondary lock 14 by the spring 54. The release element 88 of the latch bolt 30 comes into contact with the latch opening (opening edge) and is thereby triggered so that the latch bolt 30 can extend further out of the secondary lock 14 than the neutral position.
  • the locking device 10 reaches a limit position in which the latch bolt 30 reaches a (second) extended position relative to the secondary lock 14 (cf. Figure 5 ).
  • the latch bolt 30 actuates the release lever 44 via the first arm 92, so that the second arm 94 with the recess 72 in the swivel bolt 32 just disengaged.
  • the swivel bolt 32 is triggered (released) and driven by the spring 52 (abruptly) pivoted into a position pivoted out of the secondary lock 14 (cf. Figure 6 and 7th ).
  • the latch bolt 30 acted upon by the spring 54 can also extend completely out of the secondary lock 14.
  • the locking levers 46, 48 secure the latch bolt 30 and the swivel bolt 32 against being pushed back. The locking device 10 is thus in the (automatically triggered) locking position.
  • the main lock 12 must be actuated, for example by means of the handle follower 18 or lock cylinder 20. This drives the drive rod 24 and thus also the link 40 coupled to the drive rod 24 (displacement to the in Figure 8 and 9 upper end of the secondary lock 14).
  • the two-armed latch lever 50 is pivoted by the latch connector 42 via the first arm 102.
  • the free end of the second arm 104 of the latch lever 50 comes into contact with the locking lever 48 for the latch bolt 30, so that the latch bolt 30 can be pushed into the secondary lock 14 at all (deactivation of the backpressure protection of the latch bolt 30).
  • the second arm 104 comes into contact with the delimiting projection 112, so that the latch bolt 30 is drawn into the secondary lock.
  • the upper end 40 'of the link 40 comes into contact with a push-back section 81 of the locking lever 46, the latter being swiveled away from the swivel bolt 32 so that the swivel bolt 32 can be swiveled in at all (deactivation of the swivel lock 32).
  • the guide nose 96 comes into contact with the guide surface 100 so that the swivel bolt 32 is pivoted into the secondary lock 14 (cf. Figure 8 and 9 ).
