Definitions

  • the present invention relates to a square driving pin of a lock of a door or window.
  • the devices for opening and closing a door or window usually have a lock with a deadbolt and/or latch control mechanism contained in a box recessed in the door or window, a handle and a square pin which connects the handle to the mechanism of the lock to transmit the rotation of the handle to a control cam of the mechanism.
  • the square pin To allow the correct operation of the lock, the square pin must be precisely and stably fixed in a hole of the control cam of the mechanism of the lock.
  • one of its ends is provided with a rotatable fixing anchor for fixing to said hole and an oblique channel for inserting a driving screw of the fixing anchor.
  • the installer After inserting the end of the square pin inside the hole, the installer inserts the screw by means of the use of a tool, such as a screwdriver or an Allen wrench.
  • a tool such as a screwdriver or an Allen wrench.
  • a lock of this type greatly limits design choices because, for example, a cover plate with a reduced size that would leave the access hole uncovered can never be installed.
  • the technical task addressed by the present invention is accordingly to realise a square driving pin of a lock of a door or window that enables the decried technical drawbacks of the prior art to be eliminated.
  • one object of the invention is to realise a square driving pin of a lock of a door or window which is adaptable in a versatile manner for installation on doors or windows of various type.
  • Another object of the invention is to realise a square driving pin of a lock of a door or window that can be installed extremely easily, rapidly and precisely.
  • Another object of the invention is to realise a square driving pin of a lock of a door or window that guarantees the necessary fixing stability and a correct operation of the lock.
  • a square driving pin of a lock of a door or window comprising a longitudinal body adapted to engage in a hole of a control cam of the mechanism of the lock and a fixing anchor for fixing said pin to said hole, said longitudinal body having at a first end a housing for said fixing anchor, said fixing anchor being rotatable between a release position of said hole in which it is retracted into said housing and a fixing position for fixing to said hole in which it is protracted from said housing, characterised in that it further comprises a driving rod of said fixing anchor positioned in an axial cavity of said longitudinal body.
  • the rod has a thread engaged in a counter-thread of the axial cavity.
  • the rod has a head positioned outside a second end of said longitudinal body, said head having a mark for engaging a driving tool of the rod.
  • the axial cavity leads into the housing to engage the rod with the fixing anchor.
  • the anchor has a first and a second coupling tooth on opposite sides of said hole.
  • the pin comprises a hinge axis for hinging the fixing anchor on the longitudinal body, the first and second coupling teeth are positioned opposite said hinge axis.
  • said anchor has a gripping cam of the movement from said rod.
  • the housing is formed by an axial slot of the longitudinal body that extends as far as said first end.
  • the first and the second tooth interfere with stop walls provided in said longitudinal body to limit the rotation of said fixing anchor.
  • the invention finally discloses a lock which comprises a square pin corresponding to that which is described above.

  • figure 6 shows a detail of the pin of figure 1 after its installation in the square hole of a lock.
  • a square driving pin of a lock of a door or window is shown, indicated in its entirety by reference number 1.
  • the pin 1 comprises a longitudinal body 2 adapted to engage in a hole 3 of a control cam 30 of the mechanism of the lock 4, and a fixing anchor 5 for fixing to the hole 3.
  • a first end 6 of the longitudinal body 2 intended to engage in the hole 3 has a housing 7 for the fixing anchor 5.
  • the fixing anchor 5 is rotatable between a release position of the hole 3 in which it is retracted into the housing 7 and a fixing position for fixing to the hole 3 in which it is protracted from the housing 7.
  • the pin 1 further comprises a driving rod 8 of the fixing anchor 5 positioned in an axial cavity 9 of the longitudinal body 2.
  • the driving rod 8 has a thread 10 which engages in a counter-thread 11 present in the axial cavity 9.
  • the rod 8 has a head 12 positioned outside a second end 13 of the longitudinal body 2.
  • the head 12 has a mark 26 for engaging a driving tool 14 of the rod 8.
  • the driving rod 8 can be for example, but not limited to, a screw having a head and a threaded stem.
  • the axial cavity 9 leads into the housing 7, realised in the first end 6 of the longitudinal body 2, for engaging the rod 8 with the fixing anchor 5.
  • the housing 7 is formed by an axial slot 27 of the longitudinal body 2 which extends from an intermediate position to the first end 6 of the longitudinal body 2.
  • the slot 27 extends linearly through two opposite sides la, lb of the longitudinal body 2 and has a first end portion 24 on one side la and a second end portion 25 on the other side lb of the two opposite sides la, lb of the longitudinal body 2.
  • the two end portions 24, 25 are positioned at different axial distances from the first end 6 of the longitudinal body 2.
  • the fixing anchor 5 has a first 15 and a second 16 coupling tooth which are positioned on opposite sides 17, 18 of the hole 3.
  • the hinge axis 19 of the anchor 5 on the longitudinal body 2 is positioned transversely with respect to the axis of extension of the longitudinal body 2, in particular at the slot 27.
  • the first and the second coupling tooth 15, 16 are positioned opposite the hinge axis 19.
  • the first and the second coupling tooth 15, 16 interfere with a first stop wall 21 and a second stop wall 22 provided in the longitudinal body 2 that limit the rotation of the fixing anchor 5.
  • the fixing anchor 5 advantageously has a gripping cam 20 of the movement from the rod 8.
  • the method for installing the square pin 1 inside the hole 3 of the lock according to the present invention is described below. After inserting the first end 6 of the longitudinal body 2 in the hole 3, the installer screws the rod 8 which, advancing through the cavity 9 towards the first end 6 of the longitudinal body 2, goes to engage the cam 20.
  • the rod 8 thus engages the cam 20, as illustrated in figure 4 and 5, rotating the fixing anchor 5 from the initial release position to the fixing position to the hole 3.
  • the anchor 5 is protracted from the housing 7 and its first 15 and second 16 coupling teeth engage the opposite sides 17, 18 of the hole 3.
  • the square pin 1 is stably fixed to the hole 3.
  • the fixing anchor 5 is never completely insertable into the housing 7 thanks to the presence of a first stop wall 21 of the longitudinal body 2 against which the first coupling tooth 15 abuts and a second stop wall 22 of the longitudinal body 2 against which the second coupling tooth 16 abuts.
  • the first wall 21 and the second wall 22 correspond to the end portions 24, 25 of the slot 27.
  • the access hole can have a smaller size because the installer operates in axis with the square pin.
  • the cover plate of the access hole can be chosen with the maximum freedom, with the desired shape and size.
