Patent Description:
The known devices of this kind usually have a handle, a square drive pivot for driving a mechanism 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 pivot must have for connection with the lock, it is necessary to provide products that differ only in the length of the square pivot.

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

<CIT> discloses a manual control device for manually controlling a lock of a door or window according to the preamble of claim <NUM>.

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 a 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, a drive pivot of the lock engaged in the axial cavity of the neck of the handle, a block that is fixable to a profile of the door or window, and a rotation bushing for rotating the handle that extends from said neck of the handle and engages a circular hole of said block into which said pivot is inserted, characterized in that said block supports a rotor module solid in rotation with said pivot and having quick locking means for extracting said pivot from said block, whereby.

Preferably said rotor module has a support base supported in rotation by said block and having a passage opening for said pivot.

Preferably said support base is housed in said circular hole.

Preferably said support base is complementarily shaped with said circular hole.

Preferably said hole and said support base have mutual coupling and rotational guide means for said support base.

Preferably said quick locking means comprise at least one elastic element pivoted to said support base.

Preferably said elastic element is a square-frame shaped flat lamina inserted on said pivot, said flat lamina having at least two opposite sides in contact with two opposite sides of said pivot.

Preferably said flat lamina has an oscillation axis parallel to said two opposite sides thereof so as to vary the distance between said two opposite sides thereof in a direction that is orthogonal to said oscillation axis.

In a first embodiment of the invention said block is fixed to the profile of the door or window with screws.

In a second embodiment of the invention a housing of the end of the pivot provided on a plate of the lock supports a further rotor module solid in rotation with said pivot and having quick locking means for extracting said pivot from said housing.

Preferably said further rotor module has a support base supported in rotation in said housing and having a passage opening for said pivot, said quick locking means for extracting said pivot from said housing comprising at least one elastic element which is pivoted to said support base.

Preferably said flat lamina in said further rotor module has an oscillation axis parallel to said two opposite sides thereof so as to vary the distance between said two opposite sides thereof in a direction that is orthogonal to said oscillation axis.

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 the control mechanism according to the invention, illustrated by way of non-limiting example in the accompanying figures of the drawings, in which:.

Equivalent parts in the various embodiments of the invention will be indicated with the same reference number.

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 <NUM>.

The device <NUM> comprises a handle <NUM> having a grip <NUM> and an axially hollow neck <NUM>, a drive pivot <NUM> of the mechanism, a block <NUM> that is fixable to a profile of the door or window, and a rotation bushing <NUM> for rotating the handle <NUM> that extends from the neck <NUM> of the handle <NUM> and engages a circular hole <NUM> of the block <NUM>.

The pivot <NUM>, in this case a square pivot <NUM>, is inserted in the hole <NUM> of the block <NUM> and through the rotation bushing <NUM> and engages in the axial cavity <NUM> of the neck <NUM> of the handle <NUM>.

Advantageously, the block <NUM> supports a rotor module <NUM> solid in rotation with the square pivot <NUM> and having quick locking means for extracting the square pivot <NUM> from the block <NUM>.

The rotor module <NUM> has a support base <NUM> supported in rotation by the block <NUM> and having a passage opening <NUM> for the square pivot <NUM>.

The support base <NUM> is housed in the circular hole <NUM> in the block <NUM>.

In particular, the support base <NUM> is complementarily shaped with the circular hole <NUM> in the block <NUM>.

The hole <NUM> in the block <NUM> and the support base <NUM> have mutual coupling means that guide the rotation of the support base <NUM>.

Such mutual coupling means comprise a peripheral circumferential groove <NUM> of the support base <NUM> and two diametrically opposing perimeter fins <NUM> which radially extend from the hole <NUM> toward the inside of the hole <NUM> itself and are engaged in the groove <NUM>. The quick locking means for extracting the square pivot <NUM> from the block <NUM> comprise at least one elastic element which is pivoted to the support base <NUM>.

The elastic element is a square-frame shaped flat lamina <NUM> inserted onto the square pivot <NUM>.

The flat lamina <NUM> has at least two opposite sides <NUM>', <NUM>" in contact with two opposite sides <NUM>', <NUM>" of the square pivot <NUM>.

The flat lamina <NUM> has an oscillation axis parallel to the two opposite sides <NUM>', <NUM>" thereof.

For this purpose, one of the two opposite sides <NUM>', <NUM>" of the flat lamina <NUM>, in particular the side <NUM>", is constrained to a hinge <NUM> provided on the support base <NUM>.

As a result of the variation of their distance in a direction orthogonal to the oscillation axis of the two opposite sides <NUM>', <NUM>" of the flat lamina <NUM>, depending on the direction of oscillation, they respectively loosen or tighten against the corresponding sides of the square pivot <NUM> to accommodate the insertion or respectively prevent the extraction of the square pivot <NUM> from the block <NUM>.

The bushing <NUM> has quick locking means for locking the extraction of the square pivot <NUM>. The quick locking means for locking the extraction of the square pivot <NUM> from the bushing <NUM> comprise an elastic element constrained to a plane <NUM> which is inclined with respect to the axis of the bushing <NUM>.

The elastic element is once again a square-frame shaped flat lamina <NUM> inserted onto the square pivot <NUM>.

The flat lamina <NUM> has at least two opposite sides <NUM>', <NUM>" in contact with the two opposite sides <NUM>', <NUM>" of the square pivot <NUM>.

More precisely, through a helical spring <NUM> suitably positioned in the bushing <NUM> and inserted onto the square pivot <NUM>, the flat lamina <NUM> is constrained with one of the two opposite sides <NUM>, <NUM>", in particular with the side <NUM>', to a side <NUM>' of the inclined plane <NUM> which thus defines the oscillation axis of the flat lamina <NUM>.

As a result of the variation of their distance in a direction orthogonal to the oscillation axis of the two opposite sides <NUM>', <NUM>" of the flat lamina <NUM>, depending on the direction of oscillation, they respectively loosen or tighten against the corresponding sides of the square pivot <NUM> to accommodate the insertion or respectively prevent the extraction of the square pivot <NUM> from the bushing <NUM>.

For the fixing of the bushing <NUM> in the neck <NUM> of the handle <NUM> at least one anti-extraction screw <NUM> is provided, engaged in a hole <NUM> defined by grooves <NUM>, <NUM> matching the cylindrical outer perimeter surface of the bushing <NUM> and the cylindrical inner perimeter surface of the neck <NUM> of the handle <NUM>.

The rotation of the bushing <NUM> in the neck <NUM> of the handle <NUM> is also prevented by specific coupled interference elements <NUM>, <NUM> that extend radially from the cylindrical outer perimeter surface of the bushing <NUM> and, respectively, from the cylindrical inner perimeter surface of the neck <NUM> of the handle <NUM>.

The hole <NUM> and the bushing <NUM> also have interacting indexing means of the angular position of the handle <NUM>.

The indexing means comprise depressions <NUM> on the outer perimeter of the bushing <NUM> and elastically yielding protrusions <NUM> on the perimeter of the hole <NUM>.

The depressions <NUM> extend along axial generatrices of the bushing <NUM>.

The protrusions <NUM> are obtained from the material of the body of the block <NUM> and/or are separate and independent parts fixed to the block <NUM>.

In the illustrated case the protrusions <NUM> are formed either by tabs of the material of the body of the block <NUM> delimited on the long sides by reliefs <NUM> of the material of the body of the block <NUM>, or by tabs embedded in specific seats <NUM> obtained in the block <NUM>.

The block <NUM> is protected by a special mask having a hole <NUM> for the passage of the square pivot <NUM>.

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 <NUM> snap-engage in the depressions <NUM>.

The provision of multiple indexed positions also contributes to increased security against burglary: if a neutral indexed position is provided between two indexed positions associated with the two operational states, the burglar must successfully pass two indexed positions to change the operating state of the door or window, and this undoubtedly lengthens the time required to break and enter the door or window.

With reference to the solution illustrated in <FIG>, for mounting the device <NUM> on the door or window, holes <NUM> for fixing screws (not shown) are provided in the block <NUM> for fixing the block <NUM> to the profile of the door or window in the traditional manner.

The assembly of the device <NUM> takes place in the following way.

Initially the block <NUM> is fixed to the profile of the door or window through screws.

Then the square pivot <NUM> is inserted through the hole <NUM> of the block <NUM> and through the rotor module <NUM> until engaging the end of the square pivot <NUM> in its housing (not shown) provided in a known manner on a plate of the lock.

After insertion, the flat lamina <NUM> of the rotor module <NUM> prevents the extraction of the square pivot <NUM> from its housing.

Lastly the handle <NUM> is applied by inserting the bushing <NUM> in the free end of the square pivot <NUM> at a distance at least sufficient for the square pivot <NUM> to cross the flat lamina <NUM>. After insertion, the flat lamina <NUM> prevents the extraction of the bushing <NUM> from the square pivot <NUM>.

The disassembly of the device <NUM> is possible with the aid of a simple hairpin <NUM> with which access is given through a calibrated channel <NUM> to the flat lamina <NUM> so as to turn its lying plane in order to release the square pivot <NUM>. Once the handle <NUM>-bushing <NUM> assembly is removed, the square pivot <NUM> can be extracted from the housing of the lock with the use of the same hairpin <NUM> that acts on the flat lamina <NUM> this time.

Now with reference to the solution shown in <FIG>, an alternative solution is proposed for mounting the device <NUM> on the door or window.

In a known manner, the lock comprises a plate <NUM> having a housing <NUM> of the end of the square pivot <NUM>.

The housing <NUM> advantageously supports a further rotor module <NUM> solid in rotation with the square pivot <NUM> and having quick locking means for extracting the square pivot <NUM> from the housing <NUM>.

The rotor module <NUM> has a support base <NUM> supported in rotation in the housing <NUM> and having a passage opening <NUM> for the square pivot <NUM>.

To retain the rotor module <NUM> in its housing <NUM>, a retaining plate <NUM> is applied to the latter through screws <NUM>.

The quick locking means for extracting the square pivot <NUM> from the housing <NUM> comprise at least one elastic element which is pivoted to the support base <NUM>.

Also in this case, the elastic element is a square-frame shaped flat lamina <NUM> inserted onto the square pivot <NUM>.

The flat lamina <NUM> has an oscillation axis parallel to two opposite sides <NUM>', <NUM>" thereof so as to vary the distance between the two opposite sides <NUM>' <NUM>" thereof in a direction that is orthogonal to the oscillation axis.

As a result of the variation of their distance in a direction orthogonal to the oscillation axis of the two opposite sides <NUM>', <NUM>" of the flat lamina <NUM>, depending on the direction of oscillation, they respectively loosen or tighten against the corresponding sides of the square pivot <NUM> to accommodate the insertion or respectively prevent the extraction of the square pivot <NUM> from the housing <NUM>.

Initially the square pivot <NUM> is inserted through the rotor module <NUM> until engaging the end of the square pivot <NUM> in its housing <NUM>.

After insertion, the flat lamina <NUM> of the rotor module <NUM> prevents the extraction of the square pivot <NUM> from its housing <NUM>.

At this point, the block <NUM> can be inserted in the square pivot <NUM> until it crosses the flat lamina <NUM> of the rotor module <NUM> and abuts against the profile of the door or window. After insertion, the flat lamina <NUM> of the rotor module <NUM> prevents the extraction of the block <NUM> from the square pivot <NUM>.

The disassembly of the device <NUM> is possible with the aid of a simple hairpin <NUM> with which access is given through a calibrated channel <NUM> to the flat lamina <NUM> so as to turn its lying plane in order to release the square pivot <NUM>. Once the handle <NUM>-bushing <NUM> assembly is removed, the block <NUM> can be extracted from the square pivot <NUM> with the use of the same hairpin <NUM> that acts this time on the flat lamina <NUM>, and finally the square pivot <NUM> can be removed from the housing <NUM> with the use of the same hairpin <NUM> that acts on the flat lamina <NUM> this time.

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

The position of the square pivot 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 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 as conceived herein is susceptible of numerous modifications and variants, all falling within the scope of the invention as defined by the claims.
