Definitions

  • the present invention relates to a security lock comprising at least one bolt fixed on a bolt tail.
  • a security lock the housing of the locking mechanism of which is protected, at least on one side, by a shielding plate, is described in German patent application DOS No. 2601774.
  • a security lock comprising a bolt and grooves forming a single removable block is described in French patent application No. 2 560 914.
  • the grooves are fixed on at least one extension plate which protects these grooves, this plate being itself fixed on the bolt.
  • Such a lock has the advantage of allowing the bolt and grooves to be replaced en bloc, in the event of deterioration of these elements, while retaining the other parts of the lock.
  • only the grooves are protected by the plate or plates integral with the bolt, while the other parts of the locking mechanism and drive of the lock are, conventionally, arranged outside the bolt tail.
  • the object of the invention is to provide a security lock which is particularly resistant to break-ins and which, on the other hand, makes it possible to adapt the length and dimensions of the bolts without dismantling the whole of the lock.
  • the security lock according to the invention is characterized in that the bolt tail comprises a tubular profile whose internal space constitutes a housing for the locking mechanism of the lock, the side walls of said profile comprising at least an opening for the establishment of this mechanism, the latter being fixed on the lock trunk.
  • the locking mechanism is fixed to the lock box in a manner known per se.
  • the lock may comprise a bolt or a plurality of bolts fixed on the bolt tail in a removable manner.
  • the bolt tail may include a longitudinal reinforcing element fixed inside the tubular frame at the location of the bolt fixing on the bolt tail. It may also include transverse reinforcing elements fixed inside the tubular framework.
  • the bolt can be fixed on the bolt tail by screwing.
  • the bolt can comprise a first part comprising fastening members intended to cooperate with fastening members of the bolt tail for fixing the bolt on the bolt tail, and at least a second part, separable from the first, the second part being arranged around the first.
  • the bolt tail may include a longitudinal reinforcement element fixed inside the tubular frame at the location of the bolt fixing on the bolt tail. It may also include transverse reinforcing elements fixed inside the tubular framework.
  • the bolt can be fixed on the bolt tail by screwing.
  • the bolt can comprise a first part comprising fastening members intended to cooperate with fastening members of the bolt tail for fixing the bolt on the bolt tail, and at least a second part, separable from the first, the second part being arranged around the first.
  • the bolt comprises an internal part in the form of a cylindrical rod comprising a male thread extending from one of its ends over at least part of its length and screwed into a hole in the bolt tail. comprising a corresponding female thread, the other end of the rod having a head portion of diameter greater than the diameter of the rod, and constituting a rim projecting outwards relative to the axis of the rod, and a part external, separable from the internal part, in the form of a tube open at its two ends, of internal diameter substantially greater than the external diameter of the rod and comprising at one of its ends a housing of dimensions substantially greater than those of the part of head of the internal part, intended for the housing of said head part and constituting a rim projecting inwards relative to the axis of the tube, the rim of the head part rests on the edge of the housing of the external part.
  • the external part of the bolt can be made of hardened steel.
  • the lock may include a keeper fitted at its base with tenons intended to be fixed in the wall in an inclined position relative to the median plane of the keeper in the direction opposite to the angle of rotation of the opening of the door.
  • the security lock according to the invention is not only very resistant to break-ins, but has the advantage of being very easy to set up.
  • the security lock comprises four bolts 1 fixed on a bolt tail 2.
  • the bolt tail is produced using a tubular profile 3 of generally rectangular external shape and of rectangular section .
  • a vertical reinforcing bar 13 is fixed inside the tubular profile, for example using a screw 17, along one of its short sides 14.
  • the reinforcing bar can of course also be fixed to the tubular profile by welding points or by gluing.
  • the tubular profile also comprises two square tubes 18, 18 ′ of transverse reinforcement, fixed inside the tubular profile, at each of its ends.
  • the purpose of these reinforcing elements is to push back the pivot point of the assembly in the event of a break-in and consequently to increase the resistance to break-in.
  • the tubular profile 3 has openings such as 15, 16, intended in particular for the installation of said locking system, for guiding and for driving this assembly.
  • the realization of these openings in the profile tubular can advantageously be produced by laser cutting.
  • the tubular configuration of the bolt tail described above provides exceptional resistance to bending.
  • the bolts 1 are composed of a fixing screw 4 passing through an outer bushing 10.
  • the fixing screw has a male thread extending from one of its ends over approximately half the length of the screw. It further comprises a head portion 7 of outside diameter greater than that of the body of the screw constituting a flange 8 projecting outwardly relative to the axis of the screw.
  • the end face of the head part of the screw comprises a honeycomb part of hexagonal shape, and intended to receive the head of a screwdriver or other screwing instrument.
  • the sleeve 10 is cylindrical in shape and open at both ends. Its internal diameter is substantially greater than the external diameter of the screw 4 so that the screw can slide easily inside the socket.
  • the tightening of the bolts is obtained by the stop of the rim 8 of the head part of the screw against the rim 12 of the socket housing, the socket resting on the other hand against the face 14 of the bolt tail.
  • the external dimensions of the bolt tail will for example be 80 x 110 x 20 millimeters, the thickness of the wall of the tubular profile being 2.5 millimeters.
  • the flexural strength of the bolt tail in the example above is particularly important. It can be determined by calculation that this resistance is about two-thirds of the resistance that would be obtained by replacing the tube with a solid element of the same thickness.
  • the bolts fixing screws can be longer so as to cross the entire width of the tube and to be fixed on the short side of the tube opposite the short side 14 or on a vertical reinforcing bar fixed on said little opposite side.
  • the production of the bolt tail using a tubular profile whose cross-section and material can be determined according to the desired degree of security makes it possible to obtain an extreme rigidity of the assembly.
  • the choice of profile for the production of the bolt tail is made according to the resistance to bending of the tube and the possibility of having the locking mechanism inside.
  • the section and the hardness of the material used for the manufacture of the parts constituting the bolt that is to say the socket and the fixing screw, can be chosen according to the desired security.
  • these characteristics can be changed at any time because the bolts are screwed on the bolt tail and can therefore be replaced.
  • the constituent parts of the bolt, and in particular the socket may for example be made of hardened steel of great hardness. The socket is then very difficult to saw, while retaining a non-brittle core, if the latter is not soaked.
  • the bolt tail is machined so that it can slide without the bolts in the trunk of the lock. This characteristic makes it possible to mount the bolts once the lock is fixed, as well as to disassemble said bolts when adjusting the strike.
  • the keeper should preferably be equipped at its base with studs fixed in the wall and inclined with respect to the median plane of the strike in the direction opposite to the angle of rotation of the door opening.
  • at least two studs will be arranged in dovetail relative to each other.
  • the cross-section and the length of the studs can be determined by the degree of security sought, according to the results of a calculation which can be carried out in order to avoid their bending when they are subjected to a force.
  • this inclined configuration of the tenons makes it possible to avoid the rotation of the keeper on itself and forces the keeper to approach the lock, which has the result of avoiding the separation of the strike and lock assembly during excessive pushing.
