Description:
MANUAL CONTROL DEVICE FOR A LOCK OF A DOOR OR WINDOW

DESCRIPTION

The present invention relates to a manual control device for manually controlling a lock of a door or window.

The known devices of this kind usually have a handle, a square activation pin for activating the lock engaged in an axial cavity of the neck of the handle and a block for fixing the handle to a profile of the door or window.

Many of the presently known devices envisage a pre-assembly of some components which, due to the fact that it requires special tools, can be tricky and time-consuming.

For this reason, sometimes it is preferable to provide the installer with a device already completely pre-assembled and ready for installation on the door or window.

In this case the installer does not have the possibility of adapting the configuration of the product from time to time to the specific door or window on which it must be mounted.

In such a circumstance, for example in the case of doors or windows which differ in the length the square pin must have for connection with the lock, it is necessary to provide products that differ only in the length of the square pin.

It goes without saying that this considerably complicates the management of inventories and the product transport and supply logistics for the installer.

The technical task which the present invention sets itself is, therefore, to realise a manual control device for manually controlling a lock of a door or window which makes it possible to eliminate the technical drawbacks complained of in the prior art.

Within this technical task, an object of the invention is to realise a manual control device for manually controlling a lock of a door or window which is versatile and adaptable for installation on various types of doors and windows. Another object of the invention is to realise a manual control device for manually controlling a lock of a door or window that can be assembled in an extremely easy, quick and accurate way, even directly at the installation site.

Another object of the invention is to realise a manual control device for manually controlling a lock of a door or window that simplifies the storage and supply logistics of components.

Another object of the invention is to realise a manual control device for manually controlling a lock of a door or window that guarantees the necessary fixing stability and an appropriate balance of the forces acting on the various components.

The technical task, as well as these and other objects, according to the present invention are achieved by realising a manual control device for manually controlling a lock of a door or window, comprising a handle having a grip and an axially hollow neck, and an activation pin for activating the lock, characterised in that it comprises an axially hollow expandable element that can be anchored to a profile of the door or window, an axially hollow expander element solidly engaged in the axial cavity of said expandable element, and a rotation bushing for rotating the handle that extends from said neck of the handle and engages in a rotatable way in the axial cavity of said expander element, said activation pin being solidly engaged in said rotation bushing and being rotatably engaged in the axial cavity of said expander element.

In a preferred embodiment of the invention, said expander element supports a rotor module which is solid in rotation with said pin and having quick locking means to stop the extraction of said pin from said expander element.

In a preferred embodiment of the invention, said rotor module has a support base supported in rotation by said expander element and having a passage opening for the passage of said pin.

In a preferred embodiment of the invention said support base is housed in the axial cavity of said expander element. In a preferred embodiment of the invention said support base and said axial cavity of said expander element have mutual coupling and rotational guide means to guide the rotation of said support base.

In a preferred embodiment of the invention, said quick locking means comprise at least one elastic element pivoted on said support base.

In a preferred embodiment of the invention, said expandable element comprises a cylindrical body provided with a plurality of expanding sectors.

In a preferred embodiment of the invention, said cylindrical body of said expandable element has an external thread to be screwed into a hole of said profile of said door or window.

In a preferred embodiment of the invention, said expandable element has an inner thread engaged with an outer counter-thread of said expander element.

Further characteristics and advantages of the invention will more fully emerge from the description of a preferred but not exclusive embodiment of the manual control device of a lock of a door or window according to the invention, illustrated by way of non-limiting example in the accompanying figures of the drawings, in which:

figures 1 and 2 show a front and rear exploded perspective view of the device according to a first embodiment of the invention;

figure 3 shows a side elevation view of the device axially sectioned and one of its enlarged details.

With reference to the figures cited, a manual control device for manually controlling a lock of a door or window is shown, indicated in its entirety by reference number 1 , comprising a handle 2 having a grip 8 and an axially hollow neck 7, and an activation pin 4 for activating the lock. Advantageously, the device 1 comprises an axially hollow expandable element 50 that can be anchored to a profile (not shown) of the door or window, an axially hollow expander element 3 solidly engaged in the axial cavity 54 of the expandable element 50, and a rotation bushing 5 for rotating the handle 2 that extends from the neck 7 of the handle 2 and engages in a rotatable way in the axial cavity 6 of the expander element 3.

The activation pin 4, in this case a square pin, is solidly engaged in the rotation bushing 5 and is rotatably engaged in the axial cavity 6 of the expander element 3.

The end of the activation pin 4 opposite that inserted in the rotation bushing 5 is positioned in a housing fashioned on a plate (not shown) of the lock.

The expander element 3 has a cylindrical body 51 and a flat outer flange 59 at one end thereof The expandable element 50 also comprises a cylindrical body 52 provided with a plurality of expanding sectors 55 and a flat outer flange 60 at one end thereof

The expanding sectors 55 are demarcated by diametrically opposite notches 56 which extend along axial generatrices of the cylindrical body 52 starting from the end of the cylindrical body 52 opposite the flanged one.

The cylindrical body 52 of the expandable element 50 has an outer thread 53 for being screwed into a hole of the profile of the door or window.

The body 52 of the expandable element 50 also has an inner thread 57 engaged with an outer counter-thread 58 of the expander element 3.

The expander element 3 supports a rotor module 10 solid in rotation with the activation pin 4 and having quick locking means to stop the extraction of the activation pin 4 from the expander element 3.

The rotor module 10 has a support base 11 supported in rotation by the expander element 3 and having a passage opening 12 for the passage of the activation pin 4.

The support base 11 is housed in the axial cavity 6 of the expander element 3.

In particular, the support base 11 is complementarily shaped to the inner section of the axial cavity 6 of the expander element 3.

The expander element 3 and the support base 11 have mutual coupling means that guide the rotation of the support base 11.

Such mutual coupling means comprise a perimeter circumferential groove 15 of the support base 11 and two diametrically opposing perimeter fins 13 which radially extend from the expander element 3 toward the inside of the axial cavity 6 and are engaged in the groove 15.

The quick locking means to stop the extraction of the square pin 4 from the expander element 3 comprise at least one elastic element which is pivoted to the support base 11.

The elastic element is a square-frame shaped flat plate 14 inserted onto the activation pin 4.

The flat plate 14 has at least two opposite sides 14’, 14” in contact with two opposite sides 4’, 4” of the activation pin 4.

The flat plate 14 has an oscillation axis parallel to the two opposite sides 14’, 14” thereof For this purpose one of the two opposite sides 14’, 14” of the flat plate 14, in particular the side 14”, is constrained to a hinge 16 provided on the support base 11.

As a result of the variation of their distance in a direction orthogonal to the oscillation axis of the two opposite sides 14’, 14” of the flat plate 14, depending on the direction of oscillation, they respectively loosen or tighten against the corresponding sides of the square pin 4 to accommodate the insertion or respectively prevent the extraction of the square pin 4 from the expander element 3.

The bushing 5 has quick locking means to stop the extraction of the activation pin 4.

The quick locking means to stop the extraction of the activation pin 4 from the bushing 5 comprise an elastic element constrained to a plane 17 which is inclined with respect to the axis of the bushing 5.

The elastic element is once again a square-frame shaped flat plate 18 inserted onto the activation pin 4.

The flat plate 18 has at least two opposite sides 18’, 18” in contact with two opposite sides 4’, 4” of the activation pin 4.

The flat plate 18 has an oscillation axis parallel to the two opposite sides 18’, 18” thereof.

More precisely, through a helical spring 19 suitably positioned in the bushing 5 and inserted onto the activation pin 4, the flat plate 18 is constrained with one of the two opposite sides 18, 18”, in particular with the side 18’, to a side 17’ of the inclined plane 17 which thus defines the oscillation axis of the flat plate 18.

As a result of the variation of their distance in a direction orthogonal to the oscillation axis of the two opposite sides 18’, 18” of the flat plate 18, depending on the direction of oscillation, they respectively loosen or tighten against the corresponding sides of the activation pin 4 to accommodate the insertion or respectively prevent the extraction of the activation pin 4 from the bushing 5.

For the fixing of the bushing 5 in the neck 7 of the handle 2 at least one anti-extraction screw 20 is provided, engaged in a hole 21 defined by grooves 22, 23 matching the cylindrical outer perimeter surface of the bushing 5 and the cylindrical inner perimeter surface of the neck 7 of the handle 2.

The rotation of the bushing 5 in the neck 7 of the handle 2 is also prevented by specific coupled interference elements 24, 25 that extend radially from the cylindrical outer perimeter surface of the bushing 5 and, respectively, from the cylindrical inner perimeter surface of the neck 7 of the handle 2.

The expander element 3 and the bushing 5 have interacting indexing means 26, 27 of the angular position of the handle 2 comprising depressions 26 on the outer perimeter of the bushing 5 and elastically yielding protrusions 27 on the perimeter of the axial cavity 6 of the expander element 3.

The depressions 26 extend along axial generatrices of the bushing 5.

The protrusions 27 are fashioned on the cylindrical body 51 of the expander element 3.

The indexing means allow the user to perceive the correct achievement of an operating state (for example, the door or window is open, closed, or lifted in the case of transom windows) when the protrusions 27 snap-engage in the depressions 26.

The assembly of the device 1 takes place in the following way.

Initially, the expandable element 50 is screwed into the threaded hole of the profile of the door or window.

Then the expander element 3 is screwed into the expandable element 50 which due to the insertion of the expander element 3 radially expands, consolidating the anchorage to the hole of the profile of the lock.

Then the activation pin 4 is inserted through the axial cavity 6 of the expander element 3 and through the rotor module 10 until engaging the end of the activation pin 4 in its relative housing envisaged in a known manner on a plate of the lock.

The flat plate 14 of the rotor module 10 does not oppose the introduction, but prevents the subsequent extraction of the activation pin in the opposite direction.

Lastly the handle 2 is applied by inserting the bushing 5 in the free end of the activation pin 4 at a distance at least sufficient for the activation pin 4 to cross the flat plate 18.

After insertion, the flat plate 18 prevents the extraction of the bushing 5 from the activation pin 4 in the opposite direction.

The disassembly of the device 1 is possible with the aid of a simple hairpin 40 with which access is given through a calibrated channel 41 to the flat plate 18 so as to turn its lying plane in order to release the activation pin 4. Once the handle 2-bushing 5 assembly is removed, the activation pin 4 can be extracted from the housing of the lock with the use of the same hairpin 40 that acts on the flat plate 14 this time.

The manual control device of a lock of a door or window according to the invention advantageously has a structure which can be easily and quickly assembled and disassembled.

The position of the activation pin can also be adjusted in a versatile manner directly at the installation site according to the specific door or window on which the device is installed.

Finally, the manual control device of a lock of a door or window according to the invention can advantageously be installed on only one side of the door or window or on both sides of the door or window.

The manual control device of a lock of a door or 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.

In practice the materials used, as well as the dimensions, can be any according to the needs and the state of the art.
