Definitions

  • the present invention relates to a manual control device for manually controlling a lock of a window.
  • Known devices of this type normally have a handle provided with a connecting bushing, a fixing block for fixing the handle to a profile of the window having a circular engaging hole for the connecting bushing, and a square pin for activating the lock, the square pin being engaged in the connecting bushing.
  • the technical task addressed by the present invention is accordingly to make a manual control device for manually controlling a lock of a window that enables the decried technical drawbacks of the prior art to be eliminated.
  • one object of the invention is to realise a manual control device for manually controlling a lock of a window which is adaptable in a versatile manner for installation on windows of various type.
  • Another object of the invention is to realise a manual control device for controlling a lock of a window that can be assembled extremely easily and rapidly.
  • Not the least important object of the invention is to realise a manual control device for manually controlling a lock of a window that simplifies the storage and supply logistics of components.
  • a manual control device for manually controlling a lock of a window, comprising a handle having a grip and an axially hollow neck, a rotation bushing for rotating the handle that extends on the axial extension of said neck of the handle, a fixing block for fixing the handle to a profile of the window having a circular engagement hole for said bushing, and a square pin for activating the lock engaged in the axial cavity of the neck of the handle, characterised in that said bushing houses inside it at least one friction ring having a shape coupling with said square pin for the stabilisation and adjustment of the engagement position of said square pin in said axial cavity of the neck of the handle.
  • said ring is firmly housed in said bushing.
  • said bushing has a round inner section mated to said ring and said neck of the handle has a square inner section mated to said square pin.

  • said engagement hole and said bushing have interacting indexing means for indexing the angular position of said handle.
  • said indexing means comprise depressions on the outer perimeter of said bushing and elastically yielding protrusions on the perimeter of said engagement hole.
  • the length of the portion of the square pin that exits from the bushing can be adjusted, forcing the square pin to slide through the friction ring, which then firmly retains the square pin in the position reached.
  • a square pin of a sole length may thus be compatible with installing the product on a variety of windows.
  • the installer will adjust directly on the installation site the position of the square pin according to need.
  • the adjusting limit of the square pin is set by the interference of the end of the square pin with the bottom of the axial cavity of the neck of the handle.
  • the friction ring also has an active function for suppressing the vibrations that occur during normal use of the device.
  • Assembly does not require the availability of particular tools and on the contrary can be performed manually for forcing the square pin through the friction ring and forcing the bushing into the hole of the fixing block up to the snap fit of the mutual connecting means.

  • the rotation bushing 5 houses inside it at least one friction ring 10 having a shape coupling with the square pin 4 for the stabilisation and adjustment of the engagement position of the square pin 4 in the axial cavity 9 of the neck 7 of the handle 2.
  • the rotation bushing 5 has in particular a round inner section mated to the friction ring 10.
  • the neck 7 of the handle 2 has in turn a square inner section mated to the square pin 4. More particularly, as shown in figures, the friction ring 10 is firmly housed in the bushing 5.
  • a shoulder on which the ring 10 axially abuts is defined.
  • the friction ring 10 is made of rubber or of any other material that provides an appropriate friction coefficient with the material of the square pin 4.

  • the fixing block 3 has holes 18 for fixing screws (not shown) for fixing to the profile of the window.
  • the covering jig 19 has a circular passage hole 21 for the bushing 5 surrounded by a rib 22 acting as a positioning seat of the elastic element 20 that in the case in point is formed by a two- coil spring.
  • the elastic element 20 is retained in a seat by an outer shoulder 23 of the handle 2 that forms a connecting surface between the neck 7 of the handle 2 and the bushing 5.
  • the device 1 is assembled in the following manner:
  • the friction ring 10 is positioned in the bushing 5 and the square pin 4 is then inserted through the friction ring 10, forcing the friction ring 10 to penetrate for a portion into the axial cavity 9 of the neck 7 of the handle 2.
  • the elastic element 20 is fitted to the square pin 4 and then the hole 21 of the covering jig 19 and the hole 6 of the fixing block 3 are fitted to the square pin 4.
  • the toothing 11 owing to the conical lead- in element 13, is wedged between the counter toothing 12, which yields elastically until it is stepped over.
  • the covering jig 19 is clamped between the fixing block 3 and the elastic element 20, which is in turn retained in the seat by the shoulder 23.
  • the position of the square pin 4 is if necessary adjusted beforehand by modifying the amount of penetration of the handle 2 into the neck 7.
  • the covering jig 19 is at this point rotated, overcoming the reaction of the elastic element 20 until the holes 18 are uncovered, the screws are inserted and the covering jig 19 is returned to the initial position.
  • the manual control device for manually controlling a lock of a window as conceived herein is susceptible of numerous modifications and variants, all falling within the scope of the inventive concept; furthermore, all the details are replaceable by technically equivalent elements.
  • the materials used, as well as the dimensions, can be any according to the needs and the state of the art.
