Definitions

  • the present invention relates to sets of locks for doors constituted by the actual lock and its associated strike, of the type known as security lock.
  • FR-A 2 457 363 partially remedies the drawbacks of conventional strikes by providing projecting retaining means on the plate consisting of partially pressed tabs and forming anchoring spouts in the frame pierced with a hole receiving a screw screwed into this frame.
  • lock mechanism is itself vulnerable, since it always has a part in which it can be destroyed by a hole made by means of a drill.
  • the object of the invention is to remedy these drawbacks, both on existing sets of security locks and on new sets.
  • a housing is hollowed out in the door and the protective member is placed in this housing.
  • the subject of the invention is also an assembly constituted by a lock or a latch and by its associated strike, of the type in which the lock or the latch is mounted on the door set back relative to the edge thereof, characterized in that that the safe of the lock or of the bolt comprises a support block for the bolt, which extends between the latter and the surface of the door and between the edge of the latter and said safe, the latter having a housing formed at the vulnerable part of its mechanism, and a protective member freely freely rotatable in said housing, and in that the associated strike includes between the fixing screws, a massive reinforcement located in the re-entrant angle formed between the plate and his body.
  • a door 1 has been shown in the closed position with its edge 2 in a rebate 3 of a wooden frame 4.
  • a set of lock and associated keeper is mounted on the door and its frame, the lock 5 being fixed on the door 1 set back relative to the edge 2, by means of screws 6.
  • the associated keeper 7 is fixed to the frame 4, with its plate 8 extending in the rebate 3, by means of screws 9.
  • the lock assembly is shown in the locking position with its bolt 10 engaged in the keeper 7.
  • FIG. 1 it can be seen that when a weighing is applied according to arrow A on the door 1, the bolt 10 extending in overhang above the surface portion of the door 1 situated between the edge 2 of the latter and the latch 5, works in deformation and as a lever which can cause the screws 6 to be torn off at the level of the arrow B, also tending to tear off the strike 7.
  • the door 1 can easily be attacked with a drill to drill a hole parallel to the barrel 11 of the lock in order to destroy the mechanism.
  • a cavity or recess 12 for example circular, is dug in the door 1, in which there is a protective member 13 constituted for example by a disc made of treated steel, of high resistance, at tungsten or other, so that it can rotate freely in the housing 12.
  • a protective member 13 constituted for example by a disc made of treated steel, of high resistance, at tungsten or other, so that it can rotate freely in the housing 12.
  • a block 14 of support for the bolt 10 is fixed by means of a screw between the latch 5 and the edge 2 of the door, which fills very little free space between the latter and the door. , to the edge of it.
  • retaining means capable of penetrating the frame 4 are formed thereon.
  • each end of the plate 8 of the keeper by two parallel saw cuts a tongue 15 which is then folded at right angles inwards as shown in Figure 3.
  • the support block 14 it is advantageous for the support block 14 to have a sufficiently large area to prevent it from sinking into the wood of the door.
  • FIGS. 2, 4 and 5 show a set of latch and keeper comprising protection and reinforcement means according to the invention, as described above, which are applied to it during manufacture.
  • the trunk of the lock 25 is closed, on its side applied against the door 21, by a plate 26 having an extension 27 made of material, the length of which corresponds at least to that of the part 28 of the bolt 29 which projects from the trunk of the lock in the unlocked position, and of the same surface as this part, and the thickness of which fills the gap between the latter and the surface of the door 21.
  • the plate 26 has a circular housing 30, at the vulnerable part of the latch mechanism, and in which is disposed a protective member 31 of hardened steel.
  • this member 31 is coated with an adhesive to hold it in place in the housing 30 before mounting the lock. It is understood of course that this adhesive does not prevent the protective member from rotating freely in its housing if it is attacked by the drill of a drill.
  • the associated keeper 32 of the assembly is shown in FIGS. 4 and 5.
  • Its plate 33 comprises two studs 34 made from one piece, or fixed, projecting from the face of the plate which is applied to the frame in order to engage in corresponding holes previously drilled in it.
  • the pins 34 are located set back from the ends of the plate and there are provided therein two additional holes 35 between the pins 34, in order to avoid deformation in this region of the plate.
  • two holes are drilled capable of receiving the studs 34 and the protruding angle of the frame is cut in order to allow the reinforcement of the reinforcement 36. as shown at 38 (FIG. 5).
  • the procedure is the same on a wooden frame, but at least one oblique screw 39 is added in order to reinforce the fixing of the keeper.
