Description

The present invention relates to a carpentry blocker device, of the type designed to take position in the rebate of the carpentry of a door, window or the like.

The present invention relates to the field of joinery fittings of the door or window type and relates, more particularly, to the locking devices capable of cooperating with a locking fitting fitted to such joinery to, in a defined unlocking position, contribute to maintain a sash in a half-open position with respect to its fixed frame.

Usually, joinery, of the window door type, is equipped with a locking fitting whose control makes it possible, depending on the case, to keep the opening or openings of this door or window closed on the fixed frame or, on the contrary, the opening of this or these openings by rotation around a vertical or even horizontal axis with respect to said fixed frame. Some of these locking fittings are capable of occupying two unlocking positions allowing two distinct opening modes.

Thus, in the case of a window door with a tilt and turn sash, a first unlocking position, starting from the locked position, frequently allows opening of a sash by rotation around a vertical axis, while the second unlocking position leads to a limited opening by lowering at least one leaf, corresponding to a half-open position of the latter.

These locking fittings for tilt and turn opening are complex and therefore expensive, not to mention that they may prove to be unsuitable in certain circumstances, for example, in application to heavy openings.

Also, it has been developed door guard devices suitable for equipping any type of joinery and whose functionality is not dependent on two opening modes of such joinery.

Usually, these door opener devices include a fixing base often defined to take position in the rebate of the carpentry, as the case may be on the frame or the opening. On this fixing base is attached in a pivoting manner, one end of a half-opening arm, the opposite end of which cooperates, with a certain mobility, with a hooking finger fitted, conversely, to the opening or the frame.

At this end opposite to that pivotally mounted on the fixing base, this ajar arm comprises a longitudinal opening, along which the latching finger can move, when the sash is pushed back, from its closed position , in its ajar open position and vice versa.

This longitudinal opening can be configured in the form of a buttonhole. In particular, it can be provided with a release opening through which the hooking finger can escape from the half-opening arm to allow the complete opening of the sash relative to the fixed frame.

Moreover, like a locking member movable in translation under the impulse of an operating rod actuated by a locking mechanism of a fitting of the espagnolette or espagnolette-lock type, the latching finger can be integral with such an operating rod and, therefore, movable in translation under the impulse of the latter.

Such a solution is for example described in the document EP2708684 . In particular, in a first unlocked position of the locking fitting, this operating rod can push this hooking finger into the longitudinal opening of the half-opening arm in a position situating it in line with the release opening. Thus, when attempting to open the door or window, this latching finger can escape without constraint from the half-opening arm for free rotation of the sash relative to its fixed frame.

On the contrary, in a second unlocked position, the latching finger is brought into a position along the longitudinal opening of the half-opening arm which does not allow it to escape. In this case, when the operator attempts to open the door or window the sash pivots with respect to its fixed frame according to an amplitude delimited by the half-opening arm.

We know, particularly from the document EP3237708 , an opener device corresponding to the preceding description, but whose fixing base defines a keeper in which the hooking finger, like a locking member, is able to engage under the pulse of the operating rod when the locking fitting is brought into its locked position. In short, the advantage provided by this solution consists in that the stay device contributes, apart from the function of keeping the sash ajar with respect to the fixed frame in an unlocked position of the locking fitting, to the locking of joinery when this fitting is, on the contrary, brought into the locked position. Thus, this interlock device can improve the security provided by the locking fitting or replace an existing keeper.

Such an opener device nevertheless has some drawbacks.

In particular, if the opening amplitude is usually dependent exclusively on the length of the opening arm and the longitudinal opening in the latter, the length of the fixing base also becomes dependent on it in order to be able to fulfill the function of spoils. Indeed, the positioning of the latter necessarily depends on the stroke communicated to the latching finger by the operating rod of the locking fitting between its locked position and its various unlocking positions.

Another drawback of these interlock devices consists in the fact that they are liable to generate handling errors. In particular, when they are accessible to the user, once the door or window has been opened, an error in the handling of these door-opening devices having the effect of pushing the door-opening arm back into a position away from the axis of the fixing base can not only prevent the closing of this door or window, but, in addition, cause deformation of the opening arm or even damage to the level of the locking fitting.

It is within the framework of a first inventive approach that we imagined associating the striker function with an ajar device, without this being able to have any influence on the amplitude of the ajar that it provides. .

In a second inventive step, we thought of a solution making it possible to maintain, or even recall, the door-opening device in its inactive position, substantially in the plane of the joinery to which it is attached, as long as it is not solicited in its function of opening an opening relative to its fixed frame. Thus, its half-opening arm does not risk leaving this inactive position and if this were unexpectedly the case, it is automatically returned to this position, avoiding any risk of false manipulation or subsequent degradation.

To this end, the invention relates to a door-opening device, comprising a fixing base comprising a first side for application in the rebate of a frame or joinery sash, of the door or window type, and a second opposite side on which is mounted articulated, about a pivot axis perpendicular to the plane of said fixing base, a first end of a half-opening arm provided, in an opposite end part, with a longitudinal opening defined to accommodate a finger attachment equipping, respectively, the sash or the fixed frame, characterized in that at its end pivotally mounted on the fixing base, the opening arm is still mounted so as to move in a longitudinal direction, perpendicular to the axis of pivoting, according to a stroke of defined length.

According to yet another feature of the invention, in the longitudinal axis of the fixing base, the latter comprises a notch in the form of a striker plate for receiving a blocking roller fitted to the opening arm.

Advantageously, the ajar device comprises elastic return means defined to return the ajar arm by rotation substantially to the longitudinal plane of the fixing base from an angular position separated from this plane.

The advantages resulting from the present invention consist in that through its mobility in longitudinal translation with respect to its axis of pivoting, the tilting arm is capable of occupying, apart from a position of free rotation with respect to the fixing base, a position of blocking in rotation on this fixing base thanks to the cooperation of a roller blocking with a notch in the form of a striker that includes the latter.

This configuration has the advantage, compared to the state of the art, of making the lengths of the fixing base, on the one hand, and of the opening arm, on the other hand, independent, to ensure this function of striker which is also filled by the interlock device.

Obviously, by being recalled, or even maintained in the longitudinal extension of the fixing base, the half-opening arm hardly risks being accidentally brought into a position in which it can thwart the closing of a door or window.

Other objects advantageous to the present invention will appear during the description which will follow relating to an embodiment given by way of indication and not limitation.

As shown in the figures of the accompanying drawings, the present invention relates to a door-opening device 1 for application to joinery of the door or window type.

In the figure 1 it is illustrated, by way of example, a window 2 comprising an opening 3 mounted, in this case, pivoting about a vertical axis on a frame 4.

This carpentry, in this case this window 2 is equipped with a locking fitting 5, in the form of an espagnolette or locking espagnolette, located in the rebate of the opening 3. This locking fitting 5 comprises a control mechanism 6 acting on one or more operating rods 6A (visible in the figure 2 and 3 ) extending along the front upright 7 of the opening 3, or even the upper and lower crossbar(s) 8.

In this example of application, the door opener device 1, according to the invention, is installed in the carpentry rebate at the level of the upper crosspiece 9 of the frame 4.

This opener device 1 comprises a fixing base 10 having a first application side 11 intended to be attached to the carpentry rebate. In the example shown in the figure 1 , this fixing base 10 is attached to the rebate of the upper crosspiece 9 of the frame 4.

In this regard, it should be understood that a kinematic inversion is possible. In particular, if the locking fitting 5 were to equip the frame, the fixing base 10 would preferably be attached to the opening.

The present invention is therefore not limited to the example of layout illustrated in the figures.

This fixing base 10 further comprises a second opposite side 12 on which a first end 15 of a half-opening arm 16 is mounted articulated around a pivot axis 13, perpendicular to the plane 14 of said fixing base 10.

In short, if the longitudinal axis 17 of the fixing base 10 extends parallel to the plane P of the carpentry 2, equipped in the rabbet with such an opener device 1, the opener arm 16, by pivoting around of the axis 13, starts from a position substantially parallel to the longitudinal axis 17 to extend in a plane perpendicular to that P of this carpentry 2.

This opening arm 16 is also provided, in an end portion 18 opposite the first end 15, with a slot 19 of oblong shape. It is defined to accommodate a hooking member 20, preferably, in the form of a T-shaped roller. , conversely, on frame 4 or sash 3.

This attachment member 20 is defined as movable in translation under the impetus of an operating rod 6A actuated by the control mechanism 6 of the locking fitting 5. Thus, by acting on this locking fitting 5, this attachment member 20 is capable of occupying, preferably, at least one locked position 21 and, successively starting from the latter, at least two distinct positions, including a first and a second unlocked position 22, 23.

The slot 19 advantageously comprises an exhaust opening 240 through which the attachment member 20 can disengage laterally, substantially in a direction perpendicular to the plane P of the carpentry 2, when this attachment member 20 occupies the first unlocking position 22, between the locked position 21 and the unlocking position 23, as shown in the picture 3 .

On either side of this exhaust opening 240, the opening 19 in the cracking arm 16 describes notches 24, 25, one of which 24 is closer to the first end 15 of this cracking arm 16 and a notch 25 more distant. The attachment member 20, in its locked position 21, engages in the notch 24, as illustrated in the figure 2 and 6 , and, on the contrary, reaches the notch 25 when it is pushed back into the second unlocking position 23 as seen in the figure 4 and 7 .

According to a feature of the present invention, the opening arm 16 is still mounted so as to be able to move in a longitudinal direction 26, perpendicular to the pivot axis 13, according to a stroke of defined length 27. For this purpose, at its end 15, the opening arm 16 can be provided with an oblong slot through which it is mounted on the pivot pin 13.

Through this feature, the opening arm 16 is capable of being pushed back longitudinally from a position 28 of locking in rotation relative to the fixing base 10 into a position of free rotation around the pivot axis 13 and vice versa. .

For this purpose, the half-opening arm 16 comprises rotation locking means 29 capable of cooperating with complementary locking means 30 provided at the level of the fixing base 10.

Advantageously, the rotation blocking means 29 are defined by a roller 31 extending under the opening arm 16 in the direction of the fixing base 10. This roller 31 is defined able to engage in a notch in form of striker 32 that this fixing base 10 comprises as complementary locking means 30, this when said opening arm 16 is pushed back into its rotation locking position 28.

More particularly, these rotation locking means 29 and the complementary locking means 30 are able to cooperate with each other when the opening arm 16 is brought into its locking position 28 by longitudinal movement, but, in addition , on the condition that the opening arm 16 is in an angular position 33 defined with respect to the fixing base 10. This angular position 33 is that occupied by this opening arm 16 in its inactive position, it that is to say in a plane substantially parallel to that of the carpentry 2, or substantially in the longitudinal alignment of the fixing base 10. This angular position 33 is in particular that occupied by this half-opening arm 16 when the window 2 is closed, that is to say when the opening 3 is pushed back against the fixed frame 4.

In this position of the carpentry, the locking fitting 5 is capable of being actuated, in particular to lock the leaf 3 on the fixed frame 4. This action causes the attachment member 20 to reach its locked position 21 by engaging in the notch 24 of the light 19. It is finally under the action of this attachment member 20, pushed back into the locked position 21, and its interaction with the bottom 34 of this notch 24 that the half-opening arm 16 is pushed back into its blocking position 28 by movement perpendicular to the pivot axis 13 and engagement of the roller 31 in the notch in the form of a striker 32.

It should be noted that, advantageously, the stroke 27 in the longitudinal direction 26 of the half-opening arm 16, perpendicular to the pivot axis 13, is greater than the stroke necessary to pass from the position 28 of blocking in rotation of this opening arm 16 with respect to the fixing base 10, in a free position in rotation around the pivot axis 13.

In this position of blocking in rotation 28 of the opening arm 16, obtained by cooperation of the roller 31 with the notch in the form of a striker 32, the interaction of the opener device 1 with the attachment member 20 gives it a function striker contributing to the locking of the sash 3 against the frame 4.

Apart from this locking function, this interlocking device 1 may have the additional function of compression, at least of compression adjustment of the leaf 3 against the fixed frame 4 in the locked position of the locking fitting 5.

For this purpose, the roller 31 is mounted in eccentric rotation on the opening arm 16, allowing it to be adjusted at least in a direction transverse to the longitudinal direction 26 on this opening arm 16. Thus, depending on the setting chosen for this pebble 31, this one, in cooperation with the notch in the form of a striker 32, can, by action on said half-opening arm 16, result in the sash 3 being pulled against the fixed frame 4.

In a complementary manner or alternatively to the previous solution, the first end 15 of the opening arm 16 can form rotation blocking means 29A able to cooperate, in the blocking position 18 of said opening arm 16, with blocking means complementary 30A in the form of a stop 35 that comprises the fixing base 10, on its side 12 on which is pivotally mounted the opening arm 16.

This stop 35 is installed in such a way that in this blocking position 28 the first end 15 of the half-opening arm 16 extends in line with this stop 35 so as to prevent rotation of the latter. On the contrary, moved away from this blocking position 28, this first end 15 of the opening arm 16 escapes the action of the stop 35 allowing the free rotation of this arm 16.

Thanks to the travel of mobility 27 with respect to the pivot axis 13, the half-opening arm 16 can, in particular when it is arranged in the longitudinal alignment of the fixing base 10, be pushed back into the position of blocking 28 by the attachment member 20 whose movement is controlled by the locking fitting 5. Conversely, during an unlocking command of the latter, this attachment member 20 can control the longitudinal movement of this arm opening 16 to release it from this blocking position 28.

If through the travel performed by this attachment member 20 between the locked position 21 and the first unlocked position 22, this attachment member 20 essentially comes out of the notch 24 to position itself in line with the opening of escapement 240 that the slot 19 comprises in the end portion 18 of the half-opening arm 16, in its travel between this first unlocking position 22 and the second unlocking position 23, the hooking member 20 engages in the notch 25 of this slot 19. During this race, whether by action at the bottom 36 of this notch 25 or by friction with the side walls which delimit the latter, the attachment member 20 pushes the arm ajar 16 in an unlocking direction 37 which has the function of disengaging the roller 31 from the notch in the form of a striker 32. In the embodiment shown and described here by way of example, this action also has the consequence of disengaging the first end 15 of this opening arm 16 of the stop 34.

Finally, in this second unlocking position 23 of the hooking member 20, corresponding to a command printed on the ajar opening locking fitting 5 of the carpentry, the sash 3 can be pushed back into its ajar position with respect to the frame. frame 4 by cooperation between the hooking member 20 and the notch 25 of the half-opening arm 16 and pivoting of the latter on the fixing base 10 around the axis 13.

According to another feature of the invention, the ajar device 1 further comprises elastic return means 38 defined to return the ajar arm 16 by rotation to the longitudinal extension of the fixing base 10 from an angular position separated of this axis. Such elastic return means 38 have the essential function of bringing the opening arm 16 back to an inactive position, substantially in the plane of the carpentry in the event that it were moved away from it other than through the hooking member 20.

Thus, this can occur when an opening control for free rotation of the sash 3 relative to the fixed frame 4 has been requested through the locking fitting 5. In this case the attachment member 20, pushed back into its first unlocking position 22, can escape the half-opening arm 16 allowing the user to open his door or window wide. The ajar device 1, then freely accessible in the rebate, can be voluntarily or involuntarily actuated and the ajar arm 16 can be moved away from the plane P of the carpentry 2. This ajar arm 16 can subsequently prevent the opening 3 to close on the fixed frame 4, or even twist during this action.

The elastic return means 38 interacting between the fixing base 10 and the opening arm 16 remedy this risk. These elastic return means 38 can take different embodiments. Their restoring force is preferably limited to their function, that is to say capable of bringing the half-opening arm 16 back into this inactive position, without opposing the half-opening of the door or window.
