Definitions

  • the present invention relates to a lock comprising a chest with a deadbolt, a safety block passing through the trunk and provided with a control member for operate the deadbolt, and a protection device against attempted break-ins.
  • the protective devices provided to protect the locks against attempted break-ins do not give fully satisfied. They are indeed complicated and bulky. They can also be quickly removed of use by criminals or vandals.
  • the present invention proposes to remedy these disadvantages and to do this it has for object a lock having the structure indicated above and which is characterized in that the protection device comprises a shield fixed against one of the side faces of the trunk and provided with an orifice giving passage to part of the block security, as well as an add-on unit housed partly in at least one groove made in the safety block and in part in at least one recess in the face of the shield which is applied against the chest.
  • This protective device is simple, easy to install and very resistant, the shield and the organ reported to offer significant resistance to any attempted fraudulent extraction of the security block.
  • the shield is fixed against the face side of the trunk which faces outwards, and constitutes an obstacle that is difficult to overcome for criminals or vandals who usually have little time to carry out their misdeeds.
  • the shield comprises a stud provided with retaining means maintaining a reinforcement plate against the other side face of the chest.
  • the lock can resist more a long time to malicious acts, which allows him provide better protection.
  • the stud crosses the trunk and the plate reinforcement, while the retaining means are constituted by a notch against the bottom of which takes support part of the periphery of an orifice formed in the reinforcement plate.
  • the reinforcement plate can be very easily placement since it suffices to engage it with the stud at the notch in it.
  • the shield may include a second stud against which the latter is fixed so removable.
  • the second pad is located outside of the trunk, below the first stud.
  • the recess is provided at the periphery located on the trunk side of the shield hole while the insert is consisting of a U-shaped pin, both of which branches are partly received in parallel grooves formed in the opposite longitudinal faces of the block of security and the basis of which is received in the indentation.
  • branches of the pin may have two extensions opposites directed in opposite directions and received in correspondingly shaped recesses in the face of the shield which is located on the side of the trunk.
  • the base of the pin can rest on the upper part of the safety block. In other locks, it can be applied against the lower part of the safety block.
  • the lock that can be seen in Figures 1 to 3 is a mortise lock comprising in a manner known as a trunk 1 provided with a deadbolt 2, a block of safety 3 provided with a bit 4 intended to actuate the bolt dormant, and a protective device 5 to defeat to attempted break-ins.
  • the trunk 1 is housed in a mortise 6 made in the thickness of a door 7 and into which two elongated recesses 8 arranged opposite one another in the side faces of the door.
  • the recesses 8 extend vertically and deliver passage to the terminal parts of safety block 3 which can therefore be respectively accessed from the inside and from the outside.
  • the lock protection device 5 comprises a shield 9 housed in the recess 8 facing outwards.
  • This shield is provided with an orifice 10 providing passage to safety block 3 and includes a stud 11 crossing the trunk 1, and a stud 12 extending parallel to stud 11, under the lower side of the trunk.
  • the stud 11 has a notch 13 in the part superior of its lateral surface, in the vicinity of its free end which protrudes slightly in the recess 8 facing inward.
  • the stud 12 has a tapped hole 14, the entrance is located in its free end, which is in the plane of the side of the trunk which is turned towards the inside.
  • the studs 11 and 12 ensure the maintenance of a plate of reinforcement 15 against the aforementioned lateral face of the trunk.
  • the plate 15 has at its upper part a orifice 16 of which part of the periphery is supported against the bottom of the notch 13 of the stud 11.
  • the protective device 5 also includes a attached member constituted by a pin 20 in the shape of a U.
  • the two branches 20a of the pin are received in part in two vertical grooves 21 formed in the opposite longitudinal faces of the safety block 3 and in part in a recess 22 formed in the face of the shield 9 which is turned towards the trunk 1, the recess 22 extending along approximately half top of the periphery of the orifice 10.
  • the branches 20a of the pin have two extensions 20b directed in opposite directions and extending in recesses 23 of corresponding shape formed in the face of the shield 9 which faces the trunk 1.
  • the base 20c of the pin As for the base 20c of the pin, it rests on the upper part of safety block 3 and is housed in the upper part of the recess 22 located at the periphery orifice 10 of the shield.
  • the shield 9 is a particularly metallic piece resistant and provides effective protection of the trunk 1 of the lock.
  • the pin 20 is embedded in a housing delimited by the safe 1, the safety block 3 and the shield 9 she is able to withstand many attempts to fraudulently extract the security block and thus provides effective protection of the lock.
  • branches 24a of the pin 24 have two extensions 24b directed at opposite direction and extending into recesses 27 of corresponding shape provided in the face of the shield 9 which is facing chest 1.
