Abstract

The device has a drive mechanism intended to act on a locking element. A control handle (12) is actuated to return the drive mechanism from a locking position to two distinct unlocking positions corresponding to two modes of door opening, where the locking position corresponds to an intermediate position of the drive mechanism between the two unlocking positions. An anti-false-operation device is intended to prevent the passage from one unlocking position to the other unlocking position as long as the opening is not closed.

Description

The present invention relates to a door locking device, window and the like, comprising a drive mechanism capable of acting on at least one locking member and actuated by a control handle for bringing said mechanism from a locking position into at least one two distinct unlocking positions corresponding to two modes of opening of said door or window.

The present invention will find its application in the field of locking devices carpentry type lock, espagnolette or espagnolette-lock more generally it relates to the field of hardware building.

It is already known locking devices for both to lock and unlock a door or window but also to allow two modes of opening the latter.

Thus, it is quite common that such a locking device allows, from a locked position, to reach a first unlocked position to allow the opening of a window, for example, by rotating a leaf around the door. a vertical pivot axis, while brought into a second unlocked position, this locking device allows the opening of such a leaf by flipping, that is to say by rotation about a substantially corresponding horizontal axis at the bottom rail of this leaf. Obviously, adapted means limit the tilting of this leaf. Such a position is often called aeration. If these different modes of opening can be reversed in the unlocking control order, the two unlocked positions of the drive mechanism of such a locking device are systematically reached successively, starting from an extreme locking position. It is usually a control handle that actuates this rotational drive mechanism, and thereby the two unlocked positions, from the lock position are affected. In sum, the user submits the handle to a first rotation of about 90 ° to pass from the locking position in said first unlocked position while a second rotation of similar amplitude, in total 180 °, allows to pass in the second unlocking position.

This configuration has become a rule in this area primarily for aesthetic considerations. In particular, whether it is an installation on a horizontal cross member of a carpentry or on a vertical upright, unlocking position this control handle can be brought into a position as appropriate, horizontal parallel to said cross or vertical parallel to the amount of the joinery so as not to extend into the clear glazing and obscure, in part, the latter.

Knowing that it is very often the second unlocking position which corresponds to the ventilation opening of the joinery, the control handle does not extend before this clear glazing in fully open position.

Finally, current solutions have been adopted to the detriment of more technical considerations and ease of handling of this type of locking device.

In particular, it has been found that a window or French window is much more often closed or, when opened, brought into a ventilation position, in the fully open position. In short, when one comes to manipulate the locking devices, it is more frequently to bring the control handle from its locking position in the second unlocking position called aeration. However, for many people, especially with reduced mobility, this second unlocking position corresponding to a rotation most frequently of the order of 180 °, it is necessary to perform a double manipulation for, in a first mode of gripping, ensure a first 90 ° rotation of the handle and, in a second mode of gripping, continue the rotation and reach the 180 °, otherwise this position can be achieved without subjecting the wrist and forearm to a constraining rotation for such users.

Of course, the drive mechanism of such a locking device and the bodies otherwise driven are subject to large amplitude displacements generating substantial friction and, consequently, premature wear parts.

It is therefore in the context of an inventive step, and reconsidering the functionality of such a locking device, ultimately to go against the prejudices of the skilled person in the field, that the it was thought that the locking device comprises a drive mechanism whose locking position is an intermediate position between a first unlocking position and at least a second unlocking position to allow the opening of a carpentry, a part, in a first mode of opening and, secondly, in a second mode of opening.

The advantages deriving from such a design are that each of the opening positions can be reached by a reduced amplitude rotation of the control handle requiring no change in the manner of grasping the control handle during these maneuvers. .

More particularly, knowing the opening mode that it wishes to obtain, the user can seize the operating handle accordingly and move it in the unlocking direction corresponding to this opening mode with a rotation amplitude finally very low. the order of 90 °.

It is in the context of a second inventive step that it has been thought to automate all or part of the controls of such a locking device, automation made easier because of the reduced displacements to be transmitted to the drive mechanism, whether to reach any unlocking position or, from such a position, the locking position. Indeed, since the locked position is intermediate between the unlocked positions, the movements can be of lesser amplitude or even identical each time. In particular, in case of use of motor means, only a reversal of the operating direction is to be expected and an identical displacement for starting from the locking position to control the unlocking according to a first or a second mode of opening the joinery . In a solution according to the state of the art, it was necessary for such motor means to be controllable for distinct movement amplitudes according to the selected opening mode.

Similarly, in case of equipment of the locking device of elastic return means, allowing from an unlocked position, to reach the locking position automatically, such elastic means can be designed in a much simpler way compared to a solution of the state of the art insofar as the displacement printed to the mechanical members is, again, in all cases of reduced amplitude.

In particular, in an advantageous embodiment, the same elastic return means are able to ensure this recall regardless of the locked position previously selected.

For this purpose, the invention relates to a locking device, door, window or the like, comprising a drive mechanism capable of acting on at least one locking member and actuated by a control handle to return said mechanism from a position locking device in at least two different unlocking positions corresponding to two modes of opening of said door or window, characterized in that the locking position corresponds to an intermediate position of a drive mechanism between the two unlocking positions .

The advantages deriving from the present invention consist, as already indicated above, in a simplified design of the locking device, a facilitated control to reach each of the unlocked positions, a lower load of the locking device members by because of movements of lesser amplitudes of the latter during any command, ease of automation of unlocking and locking.

With reference to these figures, a fitting 1 for an opening 2, for example a window or French window, comprises one or more locking elements 4 fixed on the perimeter of the opening 2 and / or the frame 3 corresponding. This fitting 1 interacts with complementary elements 5 located respectively on the frame and / or the opening so as to ensure locking in the different positions provided for this fitting.

In particular, in the closed position of the opening, the locking element is in the intermediate position 6 of its complete travel, the two unlocking positions being marked 7 and 8 ( Fig. 4 ). A handle 12 makes it possible to actuate said fitting 1 between the various positions 6, 7 and 8.

In a complementary manner, an elastic return means 9 may be integrated into the fitting 1, so as to force it to return to this intermediate position 6. Ideally this elastic return means 9 has compact dimensions so as to integrate easily with the usual grooves profiles without requiring additional notching. This is much easier than for devices of the state of the art for which the two unlocking positions are located on the same side of the locking position, at two different amplitudes.

According to another embodiment, the fitting 1 can be equipped with a motor 10, which can easily motorize the device according to the invention. Indeed it is sufficient to provide a movement on either side of the intermediate position, of identical amplitude, which makes it very easy motorization of the device.

The locking element 4 and / or the complementary elements 5 incorporate a ramp allowing the fitting to retract at the approach of the locking position. According to another option, the fitting can still be equipped with trigger means 11 articulated on the headrest, of anti-false-maneuver type ( Fig. 6 ), which collaborate with a complementary portion of the opening 2 or the frame 3 to allow the movement of the locking elements under the action of the elastic return means when the desired position is reached.

Lastly, detection, assistance with locking / unlocking and / or assistance opening / closing functions can be integrated into the fitting 1 to increase comfort or accessibility.

As mentioned above, the locking device is equipped with an anti-false maneuvering device. This anti-false maneuvering device is configured to prevent the passage from one unlocked position to another as said opening 2 is not closed.

As mentioned above, the locking device can be equipped with elastic return means allowing, from an unlocked position, to reach the locking position automatically. In fact, such an elastic return means is configured to exert a return force on said locking member to its locking position.

Finally, as mentioned above, the fitting 1 can be equipped with a motor 10. As a result, the device can then comprise a motor 10 which is, in fact, configured to move said locking member between its positions of unlocking and locking position.
