Definitions

  • the invention relates to a bolt lock, in particular mortise lock with a cylindrical lock housing and gear drive for a bolt meshing therewith.
  • Known door locks often have the disadvantage of insufficient security under mechanical loads, e.g. in the event of a break-in.
  • the bolts of these locks cannot be reinforced to meet the security requirements.
  • the dimensions of the door lock can no longer be observed without using deviations from the specified standard when using a larger bolt, which is equivalent to an expensive custom-made product.
  • the doors are equipped or equipped with additional locks in addition to the door lock already present above and / or below this lock.
  • the bolt locks which are mainly used as additional locks, can either be screwed onto the door or invisibly worked into the door leaf, except for key engagement.
  • mortise locks Such locks incorporated directly into the door are known as so-called mortise locks. They have a square lock case and a square one on the bolt to hold the key-operated bolt adjustment mechanism and to attach it to the door on the outlet side screwed on the faceplate (end plate) with which they can be fastened in the door.
  • the recess for the lock case in the door can only be made with a milling machine or manually with a chisel.
  • the invention has for its object to provide a structurally simple mortise lock, which can be easily installed by anyone without special expertise and without much effort.
  • this object is achieved by a one-piece lock cylinder in the lock housing that completely penetrates a door leaf and can be closed on both sides.
  • the cylindrical shape of the lock housing only requires a blind hole in the front of the door leaf, which is opposite the corresponding opening in the door frame, in which the bolt includes. It is then only necessary to insert the lock housing into the receiving hole, which can optionally be produced using a hand drill, and to provide an opening for the lock cylinder in the door leaf in the installed position of the lock housing. So that the locking mechanisms no longer have to be placed on the door or the door leaf separately from both sides, as in the known locks, but rather in one piece, i.e. One-piece lock cylinder can be realized, the drive mechanism, i.e. the gear has been reduced so much that it can be accommodated in the diameter of the lock housing, which is dependent on the limited thickness of the door leaf.
  • the locking cylinder is received by a recess adapted to its profile, transversely to the longitudinal axis of the lock housing, so that an opening which at least clears this recess is to be provided in the door leaf. It is it is not absolutely necessary for the locking cylinder to merge into an oval profile section below the cylindrical part; this section could also have a different cross section. To avoid the custom-made products that are then necessary, the commercially available locking cylinders with an oval profile section are used.
  • the disengageable bolt merges into a fork-like disengagement shaft, one of the shaft legs of which is designed as a toothed rack, onto which, when a key inserted into the locking cylinder is rotated, the rotary movement is transmitted via the gearwheel meshing with it and can thus be converted into a linear movement of the bolt.
  • a stop of the lock housing at the bolt exit end limits the adjustment path of the bolt, against which shoulders of the release shaft lie.
  • the shoulders can be formed here by a release shaft having a larger dimension than the bolt, which should be only slightly smaller than the cavity of the lock housing.
  • the stop for the shoulders of the release shaft can consist of a locking ring and a washer with a central through opening for the bolt, which can be inserted into the lock housing at the outlet-side end of the bolt. This makes it possible to avoid mounting difficult, fixed stop edges or lugs in the interior of the lock housing.
  • the bolt with the two shaft projections can be inserted into the lock housing insert so that the gear is enclosed by the release shaft.
  • the shaft protrusion passed through the locking cylinder below the gearwheel secures the seat and the installation position of the locking cylinder without further measures.
  • a through hole can be provided in the lock housing on both sides at a distance parallel to the profiled recess. It is then possible to attach a security plate or rosette from the side of the door to the interior of the door by means of bolts which are passed through the through holes in the lock housing.
  • the mortise lock lock shown in FIG. 1 and designated overall by 1 consists of a hollow cylindrical lock housing 2 and a lock 3 with a release shaft 4 which can be disengaged therein.
  • the release shaft 4 is fork-shaped and, with its two shaft legs 5, 6, closes a toothed wheel 7 into one Lock housing 2 used lock cylinder 8 with a central key opening 10. While the lower shaft leg 6 is guided through a through opening 12 of the lock cylinder 8 extending in the direction of the longitudinal axis 9 of the lock housing 2 below the gear 7, the upper shaft leg 5 designed as a rack engages in the gear 7, so that by the key-operated rotation of the Gear 7, the rack 5 and thus the bolt 2 can be adjusted from the position shown in Fig. 1 to the outside.
  • the lock cylinder 8 required to disengage the bolt 3 is arranged in a recess 13 (FIG. 2) running transversely to the longitudinal axis 9 of the lock housing 2, the mortise lock lock 1 shown in FIG. 1 being assembled in such a way that first the lock housing 2 is in a Insertion hole of a door is inserted. Then the lock cylinder 8 can be inserted into the recess 13 penetrating the lock housing 2. Subsequently, the bolt 3 with its release shaft 4 is inserted into the lock housing 2 until the rack 5 is coupled to the gear 7 of the locking cylinder 8.
  • the lower shaft leg 6 below the gear 7 enters the through hole 12 of the locking cylinder 8, so that the gear 7 is completely enclosed by the two shaft legs 5, 6 when the disengaging shaft is pushed in further.
  • the lower shaft leg 6 secures the installation position of the lock cylinder 8 and essentially prevents it axially pushing out the cylinder.
  • the locking cylinder 8 which penetrates the round lock housing 2 transversely penetrates the position of the inserted mortise lock 1 and thus supports the action of the bolts or screws guided through the door leaf into the bores / threaded bores 19.
  • a disc 15 with a central passage opening 16 for the bolt 3 is inserted into a recess 14 in the lock housing 2 at the bolt outlet end held in this position by means of a locking ring 17 which lies against the disk 15 from the outside.
  • the disk 15 forms a stop and thus a limitation of the adjustment path when disengaging or locking the bolt 3.
  • the disengaging shaft 4 can only be adjusted so far counterclockwise after turning a key (not shown) which engages in the key opening 10 of the locking cylinder 8, until he lies against the pane 15 with his shoulders 18. This stop can simultaneously avoid that the connection between the rack 5 and the gear 7 is interrupted when the bolt 3 is closed.
  • the latch 3 is closed or engaged by turning the gear 7 clockwise.
  • the lock housing 2 shown in FIG. 2 has a through bore 19, which is optionally provided with a thread, on both sides at a distance parallel to the profiled recess 13.
  • the position of the lock in the door can thus be determined and, if necessary, a security plate (not shown) can be attached from the side of a door to the interior of the room, which further improves the resistance of the mortise lock 1 against mechanical influences.
  • Fig. 4 shows the mortise lock 1 inserted into a door 22 with the locking cylinder 8 penetrating the lock housing 2 transversely, which in this case ends flush with the two door leaves 23.
  • a locking cylinder protruding from the door leaves 23 can also be used, the projecting ends being able to be enclosed by shields, not shown, screwed onto the door leaves.
