Definitions

  • the present invention relates to a cylinder for actuation mechanisms.
  • cylinders typically of standardized dimensions, which are coupled to actuation mechanisms, typically frame locks or other mechanisms such as switches for the control of automatic devices (e.g. motors for opening/closing gates or doors).
  • actuation mechanisms typically frame locks or other mechanisms such as switches for the control of automatic devices (e.g. motors for opening/closing gates or doors).
  • the cylinders for actuation mechanisms typically comprise a main body (also called stator) on which there is rotatably fixed a cam (commonly named tongue) having a protruding portion adapted to operate the actuation mechanism to which the cylinder is applied.
  • the cam is mechanically coupled to a rotating body (commonly known as plug) housed in the main body and typically having a longitudinal seat for the insertion of the key.
  • a rotating body commonly known as plug housed in the main body and typically having a longitudinal seat for the insertion of the key.
  • Each of the main body and the rotating body comprises a plurality of holes designed to house suitable elements forming part of a blocking mechanism of the cylinder (i.e. respective pins, counter-pins, and, at least in mechanical actuated cylinders, springs).
  • a coded key for mechanical actuated cylinders typically comprises a handle and an elongated body having a section compatible with the section of the longitudinal seat of the rotating body and a toothing composed of teeth and/or depressions of various heights, which determine the coding or combination.
  • each pin is placed with a respective end, which contacts a respective counter-pin, at the outer circumference of the rotating body, configuration which allows the rotation of the key and of the rotating body with respect to the main body, at which corresponds the rotation of the cam which in turn, when the cylinder is inserted in the actuation mechanism, determines the actuation of the latter (for example a translation of the bolt and/or of the latch of the lock by direct or indirect actuation by the protruding portion of the cam).
  • a fundamental aspect of the cylinders for actuation mechanisms is the relative safety degree, i.e. the ability to withstand to break-in and/or tampering and/or extraction attempts.
  • the cylinders for actuation mechanisms are able to withstand extraction attempts of the rotating body from the main body, which would disable the blocking mechanism.
  • these extraction attempts provide the insertion of a self-threading screw in the rotating body parallelly to the longitudinal direction thereof and the subsequent forced extraction (in jargon called "draw") of the rotating body along the longitudinal direction itself (i.e. the direction parallel to the axis of rotation of the rotating body).
  • EP2730727 and EP2535487 describe known cylinders for actuation mechanisms.
  • Object of the present invention is therefore providing a cylinder for actuation mechanisms which has a high degree of resistance against extraction attempts of the rotating body from the main body.
  • the invention relates to a cylinder for actuation mechanisms comprising a main body having a cavity, a rotating body rotatably housed in said cavity and having an axis of rotation along a longitudinal development direction of said cylinder.
  • said rotating body has, on a respective outer surface having a longitudinal development, a groove having a (substantially) annular development centred in said axis of rotation and lying on a plane perpendicular to said axis of rotation.
  • said cylinder comprises a blocking element (rigidly and firmly) fixed to said main body and having an engagement portion which slidably engages said groove of said rotating body.
  • the rotation of the rotating body is allowed about the axis of rotation (since the engagement portion slides along the groove)
  • the engagement portion interferes with the transversal surface of the groove directed in accordance with the extraction direction, opposing (thanks to the fact that the blocking element is fixed, rigidly and firmly, to the main body) to the translation of the rotating body with respect to the main body.
  • the present invention includes solutions wherein the groove is only delimited by a transversal surface concordant with the extraction direction (i.e. a surface which faces towards the end of the rotating body distal to the notch and which is therefore able to oppose to an extraction force of the rotating body), lacking the opposite surface facing towards the notch.
  • the groove can simply be made by a shoulder at which the section of the rotating body increases going towards the notch, thus realizing a surface having an annular and radial development facing the other side.
  • the present invention in one or more of the aforesaid aspects can have one or more of the following preferred features.
  • the cylinder comprises an elastic stop ring (e.g. Seeger), distinct from said blocking element, fitted on a stop groove (distinct from said groove) obtained on the outer surface of the rotating body (in extremal or intermediate position) and having (substantially) annular development centred in said axis of rotation and lying on the plane perpendicular to the axis of rotation, wherein said stop ring has a respective surface facing a respective surface of the main body to counteract an extraction force of the rotating body directed away from a notch of the main body.
  • the blocking element of the present invention exert a draw-proof action which is added to the draw-proof action of the stop ring, without excessive complications to the cylinder structure and particularly effective since the blocking element is fixed to the main body and not to the rotating body.
  • said groove is (substantially) continuous along the whole annular development.
  • the engagement portion can freely slides in the groove against a complete turn of the rotating body.
  • said groove is delimited by a surface having a substantially transversal and annular development and facing towards a first end of the rotating body distal to a notch of the main body.
  • said surface is substantially continuous along the annular development (i.e. it can be continuous or it can have interruptions along the annular development which however have a smaller width than the width of the engagement portion). In this way the contrasting action to the extraction of the rotating body takes place for any angular position of the latter.
  • said blocking element has a main development direction.
  • said blocking element comprises, more preferably consists of, a pin.
  • said engagement portion is an end portion of said pin along said respective main development direction of the blocking element. In this way the blocking element is rational and simple.
  • said blocking element has a section perpendicular to the respective main development direction with circular shape. In this way the blocking element can be fixed to the main body by screwing and/or a specific alignment is not required.
  • said engagement portion has a perpendicular section smaller than a perpendicular section of a remaining portion of said blocking element. In this way the encumbrance of the groove is reduced.
  • said main body comprises a seat which houses said blocking element.
  • said seat extends with continuity from an inner surface of said cavity to an outer surface of said main body. In this way it is possible to insert the blocking element from the outside of the main body to allow the engagement portion to occupy part of the cavity.
  • said seat has a (main) development direction which forms an angle with said longitudinal direction greater than or equal to 45°, more preferably greater than or equal to 60°, and/or less than or equal to 100°, more preferably less than or equal to 90°, said angle being turned opposite to a notch of the main body and on the side of the blocking element.
  • said (main) development direction of the seat is incident to said axis of rotation.
  • the main development direction of the seat is (substantially) perpendicular to said longitudinal direction, more preferably radial with respect to said axis of rotation.
  • said seat has a thread, more preferably is a threaded hole, and said blocking element comprises a respective thread counter-shaped to said thread of said seat, for example the blocking element is a screw.
  • the blocking element is (rigidly) fixed to said main body.
  • said cylinder comprises one or more additional blocking elements, each one fixed to said main body (for example angularly uniformly distributed with respect to the axis of rotation) and having an engagement portion which slidably engages said groove of said rotating body or possibly a respective additional groove of said rotating body having the same claimed features of said groove. In this way the draw-proof action is enhanced.
  • said blocking element and/or said one or more additional blocking elements is/are fixed to said main body by screwing, by mechanical joint or by gluing.
  • said cylinder comprises a cam rotatably fixed to the main body and (selectively) couplable to said rotating body to rotate about said axis of rotation.
  • the cam typically serves to operate the latch and/or the bolt of the lock or an electric switch.
  • said main body comprises a notch configured for housing a cam, said cavity being in communication with said notch. In this way the rotating body is couplable to the cam.
