Definitions

  • the invention relates to a lock, which is suitable, for example, for locking a door.
  • Such locks are specified in DIN 18251. These locks have a housing (lock case) in which a bolt and a latch are guided. The bar shows a blunt face. In the locked position, the front end projects into a recess in a door frame, which is often reinforced with a striking plate. In the release position, the latch is withdrawn from the recess. The movement between these two positions is done by turning a key, cylinder lock or knob.
  • the latch has a bevelled end face and is held in the locked position by a spring. Due to this design, it can snap into another recess in the door frame when the door slams shut. To open the latch, pull it back against the force of the spring by depressing a door handle or turning a key or knob.
  • a tiltable latch is disclosed in GB-A-20 14 230.
  • the bolt can be tilted about a horizontal axis perpendicular to a locking surface of the bolt.
  • the electromagnetic actuation also requires a lot of energy with this lock.
  • tiltable bars or bar parts are specified in DE-A-4019350 and US-35 82 119.
  • the invention is therefore based on the object of specifying a lock that can be operated with little energy expenditure.
  • the rotatable, foldable or tiltable locking lug of the invention enables a particularly short actuation path without great effort. The energy required to open and close the lock can thus be kept low.
  • the bolt arrangement can form the bolt or the latch of a door lock.
  • the invention is also suitable for other locks, such as furniture locks, which are to be locked or opened with little energy expenditure.
  • the lock can be unlocked electrically, in particular electromagnetically, by means of a remote control or by an electronic proximity-sensitive access control system. The electrical energy required for operation can then be taken from a small built-in battery that still has a lifespan of several years.
  • claims 3 and 4 have the advantage that the locking lug only has to tilt from the locked position into the release position by a small angle. If the lock is installed in a door, the locking lug does not need to be completely removed from the recess in the Withdraw the door frame. The complete release of the lock then takes place by pressing the door, the locking lug sliding out of the recess due to its inclined blocking surface while it pushes the bolt arrangement into the lock case.
  • the configurations according to claims 5 and 6 are mechanically particularly stable.
  • the toggle lever can in its extended position (corresponding to the locking position of the locking arrangement) and as long as it is prevented from kinking by the locking pin, absorb large compressive forces in the longitudinal direction without there being a risk of the lock opening unintentionally.
  • the pressure forces are essentially directed past the locking pin, which thereby always remains easily movable.
  • claims 8 and 9 bring about a simple return of the toggle lever into the extended position and thus a return of the locking lug into the locked position as soon as the lock has been opened by pushing back the locking arrangement.
  • the features of claims 3 and 4 there is a particularly simple handling, since the locking lug of the unlocked lock is automatically returned to the locked position when the door is pressed on or pulled, without further manipulations being carried out or electrical energy being used for motorized operation should be.
  • Figure 1 shows a door 1 viewed from above, which abuts a door frame 2.
  • a lock is inserted into the door, which is received by a lock case 3.
  • the lock case 3 is closed with a faceplate 4.
  • a locking lug 11 of a bolt arrangement 10 projects into a recess 5 in the door frame 2.
  • the edges of the recess 5 are reinforced with a locking plate 6.
  • the bolt arrangement 10 replaces the case of a conventional lock according to DIN 18251.
  • the bolt arrangement 10 is arranged to be longitudinally displaceable in the lock case 3 and is held by a compression spring 7 in the advanced, blocking position shown, in which the locking lug 11 protrudes from the lock case 3.
  • a locking surface 12 of the locking lug 11 forms a stop against the door frame 2 and the locking plate 6 and prevents the door from being opened when force is applied in the direction of the arrow A.
  • the direction of the longitudinally displaceable locking arrangement 10 is parallel to the locking surface 12 and both are perpendicular to the arrow A. As a result, the bolt arrangement does not leave its advanced, blocking position when the force is applied.
  • the bolt arrangement 10 is provided with an attack 13 on which a door handle mechanism (not shown) can be used to pull the bolt arrangement 10 back against the compression spring 7 into the lock case 3 and to release the door.
  • a door handle mechanism (not shown) can be used to pull the bolt arrangement 10 back against the compression spring 7 into the lock case 3 and to release the door.
  • FIG. 2 represents a side view of the latch arrangement from the direction of arrow A.
  • the locking arrangement 10 includes a locking body 14.
  • the locking lug 11 is rotatably fastened to the locking body 14 by means of a joint 15.
  • the axis of rotation of the joint 15 is aligned parallel to the locking surface 12.
  • the locking lug 11 is articulated with a first lever element 16 connected, which in turn is articulated to a second lever element 17, which is finally also articulated to the bolt body 14.
  • the lever elements form a toggle lever 16, 17.
  • the toggle lever 16, 17 is stretched and, starting from the locking lug 11, is oriented approximately tangentially to an imaginary circle around the joint 15.
  • the toggle lever prevents the locking lug 11 from rotating about the joint 15 and the latch arrangement 10 forms a rigid structure. If the lock is in the locked position as shown in FIG. 1 and an attempt is nevertheless made to open the door 1 by force in the direction of arrow A, the frame 2 exerts a force on the locking surface 12 of the locking lug 11. This force causes a torque for the locking lug 11 with the joint 15 as the center of rotation.
  • the toggle lever 16, 17 is loaded in the longitudinal direction under pressure.
  • the joint 15 and the articulated connections between the lever elements 16, 17 and the locking lug 11 and the locking body 14 are provided with guide pins 18 inserted with play, which at least on the toggle levers 16, 17 only provide a loose guide, but do not absorb the pressure forces occurring there have to. Because when the force is applied, the locking lug 11, the locking body 14 and the lever elements 16, 17 lie directly against one another in order to transmit the forces acting on the locking lug 11 to the locking body 14 and from there to the lock case 3.
  • the toggle lever 16, 17 is prevented from buckling by a locking pin 19. In Figure 1, this extends perpendicular to the plane of the drawing. It is connected to the armature of an electromagnet (not shown) attached to the lock case 3.
  • the lock of the present exemplary embodiment permits electromagnetic unlocking.
  • the already mentioned electromagnet lifts the locking pin 19 out of the drawing plane of FIG. 1. This movement is smooth, even if forces are exerted on the door 1 and thus also on the toggle lever 16, 17, since the locking pin 19 is largely decoupled from these forces.
  • the toggle lever 16, 17 is no longer prevented from buckling when the locking pin 19 is raised.
  • the toggle lever 16, 17 is provided with a spiral spring 20, which causes it to snap when the locking pin 19 is removed.
  • the buckled position is shown in Figure 3.
  • the latch arrangement When the toggle lever 16, 17 is buckled, the latch arrangement is in its release position.
  • the knee lever 16, 17 is shortened by the buckling and the locking lug 11 rotates or tilts by a few degrees around the joint 15.
  • the joint 15 is arranged at the level of the cuff 4 so that the locking lug 11 is small and sufficient within the recess 5 can tilt far.
  • the locking surface 12 In contrast to the locking position, see Figure 1, the locking surface 12 is no longer parallel to the direction in which the locking arrangement 10 can be moved against the force of the compression spring 7. It is also no longer perpendicular to the force with which the door 1 is normally pushed open, see arrow A in FIG. 1.
  • the locking pin 19 advantageously driven by a spring (not shown), falls back from above onto the toggle lever 16, 17.
  • the locking pin 19 comes to rest on top of the first lever element 16. It falls on the lower part of a step 21 indicated by a broken line in FIG. 3.
  • the part lying lower with a view from above of the drawing level in FIG. 3 is on the side of the step 21 facing the locking lug 11 as soon as the door 1 is complete is opened and the locking lug 11 no longer abuts the frame 2, the bolt arrangement 10 is pushed out of the lock case 3 by the compression spring 7 again.
  • the step 21 slides along the locking pin 19 and presses the toggle lever 16, 17 into its extended position. At the same time, the locking lug 11 is rotated into its locked position by the extending toggle lever 16, 17.
  • Step 21 is not shown in FIG. 1 for reasons of clarity.
  • a leaf spring can also be attached in the rear area of the lock case 3, which exerts a force on the toggle lever 16, 17 when the latch arrangement 10 is pushed back, which stretches it again.
  • the leaf spring can be attached to the toggle lever 16, 17 on the side to which it buckles and run against a stop on the lock case when the bolt arrangement is pushed back, so that it is tensioned and stretches the toggle lever 16, 17.
  • the exemplary embodiment thus represents a door lock that is very secure against the use of force and attempts to manipulate and yet is extremely low-energy electrical or unlocked electromagnetically. It does not have to be preloaded to lock, because this happens automatically when the door is opened.
