Definitions

  • the present invention relates to the field of locksmithing and more precisely the locksmith assemblies comprising cylinders with a so-called European profile.
  • cylinders housed in a lock and whose actuation by a suitable key makes it possible to control the opening or closing of this lock.
  • These cylinders comprise a stator inside which is adapted to rotate a rotor when a key of dimensions and adapted shapes is inserted.
  • the end of the rotor facing outwardly of the lock has a key insertion slot while the opposite end of the rotor, all the way towards the inside of the lock, is extended axially out of the stator by means of clutch of a rotary member for actuating the bolt of the lock.
  • cylinders with a European profile are those in which the cylinder body has a lateral extension of substantially elongate shape.
  • the lateral extension is disposed vertically under the body of the cylinder.
  • Known European profile cylinders with two inputs which consist of a one-piece cylinder which has at each axial end a key insertion slot, so that a single cylinder re, of length substantially equal to the thickness of the door, allows to present an insertion slot on both sides of the door.
  • a central rotary member is adapted to be housed in the center of this monobloc cylinder so as to engage with each of the two rotors.
  • These cylinders have a standard size, in industrial manufacture, so that it is not possible to adjust to the thickness of a door slightly different from the standards without the end of the rotor forming the entrance face the key just protrudes slightly from the door.
  • the size of the one-piece bar to be used depending on the thickness of the door is chosen so that it extends from one to the other of the so-called European profile half-cylinders.
  • the patent document ⁇ 067040 discloses such a device, which however has the disadvantage of remaining in an assembly where it is not possible to exactly adjust the length of the bar to the required size and where there is therefore the risk that the outer cylinder protrudes from the door, even slightly.
  • the invention is intended to design a locksmith assembly that allows a possible adjustment to a door of non-standard thickness, so as to prevent the cylinder from protruding from the door and thus to eliminate any possibility of grab the cylinder from the outside with pliers to break it.
  • the invention thus proposes, in this context, a device for coupling two half cylinders with a so-called European profile by a bar system, wherein said system comprises two bars each having a first end adapted to be fixed to one of the half rolls and a second end hooked to an intermediate connecting piece which extends longitudinally between the half rolls, by via hooking elements carried respectively by said connecting piece and by said second end of the bar.

Thus, they ensure a continuous shape in the axial extension of the bar when they are coupled and thus improves the rigidity of the assembly by the continuity of the section.
  • the intermediate piece is made of a more robust material than the material of the bars.
  • it has the advantage of solidifying this assembly area, compared to a monobloc strip, while it is this area that presents the most risk of rupture during an attempted break-in.
  • the invention also relates to a locksmith assembly in which two half-cylinders with a so-called European profile, each comprising a lateral extension of a body in which a stator is a receiver of a driving rotor of a rotary lock-control element. , are coupled by an adjustable device.

  • the intermediate coupling part 8 should be placed under the rotating element. It is indeed this piece intermediate, as will be described below, which has a shape adapted to allow passage to the rotary control element for its good rotation. It is then understood that the longitudinal position of the intermediate connecting piece is fixed by the design of the lock and the location of the bolt, and that the adjustable connection device according to the invention makes it possible to propose bars of greater or lesser size. depending on the position of the intermediate piece and the distance between it and the half cylinders to be connected.
