  • the present invention relates to a modular cylinder for locks and the like.
  • Each lock is designed for installation on a door or on a leaf that has a specific thickness.

  • the cylinder 1 furthermore comprises at least one actuation device 7, which is provided with a bit 8 which is functionally associated, when the cylinder 1 is installed in the respective leaf, with at least one component chosen between a spring latch and a bolt, for the actuation thereof (in particular, the rotations of the bit 8 can cause the extraction and/or retraction of the bolt and also the retraction of the spring latch).

  • the connecting bars 9 can advantageously be a plurality: in this case, each bar 9 has a specific length and a respective distribution of a series of holes 12 and 14, for the assembly of modular cylinders 1 of different length. This result is achieved by installing a different number of transmission elements 6 and by proceeding with a different placement of the actuation device 7 (with respect to the main units 2 and to the transmission elements 6).
  • each transmission element 6 can be arranged upstream or downstream of the actuation device 7 (optionally even by installing multiple transmission elements in series upstream or downstream of the actuation device 7 and by instead inserting none on the opposite side, i.e., downstream or upstream of said device 7).
  • the actuation device 7 substantially at the centerline (substantially symmetrical arrangement) or off-center (even with great asymmetry).

  • each main unit 2 comprises, on its terminal front 17 which lies opposite the one provided with the seat 5 for the respective key, respective contoured protrusions and recesses, for coupling to at least one other component chosen between a transmission element 6 and an actuation device 7.
  • the protrusions and recesses that are present on the terminal front 17 have the purpose of rendering stable, despite the ease of assembly, the coupling among the various components, which must be matched by optimum transfer of motion from the rotor 4 to the bit 8 of the actuation device.
  • Each transmission element 6 can in fact efficiently comprise, on at least one first face 18 of the respective rotor core 16, specific recesses and tabs the shape and dimensions of which are complementary to the protrusions and recesses that are present on the terminal front 17 of the rotor 4 of the main unit 2.
  • Each transmission element 6 furthermore comprises, on the second face 19 which lies opposite the first phase 18, respective contoured protrusions and recesses which are identical to those of the front 17 of the rotor 4 of the main unit 2.
  • This particular shape allows the interchangeability and modularity of the transmission elements and therefore their optional series arrangement, in order to increase the length of the cylinder 1, depending on the specific requirements set by the thickness of the installation leaf.
  • the actuation device 7 can validly comprise a rotatable bit 8 which is functionally associated with a respective shaft 20 (optionally with the interposition of specific transmission members 21).
  • the shaft 20 in practice constitutes an extension which pushes the transmission members 21 when the key is inserted.
  • the rotatable bit 8 furthermore comprises, on its front surface and on its rear surface (in greater detail, on the front surface and on the rear surface of the transmission members 21 on which the bit 8 is coupled, optionally with the interposition of the shaft 20, which acts as an extension) specific receptacles and raised portions whose shape and dimensions are complementary with respect to the protrusions and recesses that are present on the terminal front 17 of the rotor 4 of the main unit 2 and/or on a second face 19 of a respective transmission element 6.
  • This particular shape allows easy assembly of the cylinder 1 according to the invention.
  • the spacer 10 is substantially shaped like an inverted letter U, forming a lower hollow whose shape and dimensions are complementary to those of the respective connecting bar 9 for stable coupling thereto: in practice, the spacer 10 can be fitted on the bar 9 (constructive possibilities in which a prismatic coupling, of the type of a dovetail coupling and/or a contoured coupling, is provided are not excluded).
  • the mutually opposite side walls of the spacer 10 conveniently comprise at least one respective through opening 10a for the accommodation of at least one element for coupling to the connecting bar 9.
  • the upper plate for interconnection of the side walls of the spacer 10 comprises an upper face provided with a cylindrical concavity, in order to allow the passage without interference of the bit 8 of the actuation device 7 upon a rotation thereof imposed by the rotor 4 of the main unit 2.
  • the stator 3 of each main unit 2 can advantageously comprise a transverse notch 22 which forms a prefracture line. If break-in attempts occur which provide for pulling the cylinder 1 out of the installation leaf 1 by means of a grip tool (for example pliers, a vise or a tool of that type), the stator 3 will break along the transverse notch 22 and the remaining portion of the cylinder 1 will remain integral with the leaf, maintaining the configuration for locking the rotor 4 with respect to the stator 3 (the release of which is possible only by using the respective key) and thus preventing the opening of the leaf on the part of the person who is attempting the break-in.
  • a grip tool for example pliers, a vise or a tool of that type
  • stator 3 of the units 2 and the stator casing 15 of the transmission elements 6 comprise respective slots 23 and 24 designed to accommodate the connecting bar 9.
  • the slots 23 and 24 can have a simple prismatic configuration, but it is not excluded to provide them with particular shapes, in order to define with the bar 9 actual prismatic pairs which prevent any mutual movement of the components involved except for longitudinal translation. Longitudinal translation is locked by means of the locking means 11 , once the exact geometry of the cylinder 1 that one intends to assemble has been identified.
  • the connecting bar 9 can be constituted by a single prism made of material with high mechanical strength (for example a metal, in particular a steel appropriately provided with additives, a composite or a ceramic derivative).
  • the bar 9 it is not excluded to provide the bar 9 by means of a stacking of laminas arranged side-by-side and/or superimposed: by adopting laminas with different mechanical characteristics (for example by alternating rigid and very hard laminas with more easily deformable laminas, which in the tension-deformation chart have a particularly conspicuous portion that corresponds to plastic deformations) it is possible to combine their properties, increasing resistance against pulling the cylinder 1 out of the leaf.
  • laminas with different mechanical characteristics for example by alternating rigid and very hard laminas with more easily deformable laminas, which in the tension-deformation chart have a particularly conspicuous portion that corresponds to plastic deformations
  • the present invention solves the problems previously described by proposing a modular cylinder 1 which can be easily adapted to doors/leaves substantially of any thickness.
