Description

The invention relates to a door or window cracking device comprising a compass arm whose first end is mounted to move in translation and / or in rotation on a first support plate and whose other end is movable at least in rotation on a second support plate, at least one of the ends of said arm being provided with a locking member, such as a roller cooperating with a striker equipping, as the case may be, the first and / or the second support plate, said striker comprising a opening engagement and disengagement of said locking member in the striker, this cracking device being further provided with locking means to prevent the release of said locking member of the striker, on these locking means acting the control means of manual unlocking in which intervene, moreover, locking means with manual unlocking control.

The present invention relates to the field of building hardware and relates, in particular, to cracking devices for a door or window.

In particular, this cracking device, according to the invention, will find its application on the doors or windows tilt and turn or whose opening (s) are single rotation.

In this regard, it is known to limit the opening of a door or window opening by means of a cracking device. In particular, such a device, when applied to a window located at a certain height of the ground, contributes to safety by avoiding the risk of falling, including a child, inadvertently handling the joinery.

It is also common to use such cracking devices to maintain an opening partially open position allowing ventilation of a home while preventing any intrusion.

He is particularly well known by the document DE-A-196 34 965 , a cracking device essentially comprising a compass arm whose end is provided with a roller adapted to engage in a keeper which, through a support plate or equivalent, is fixed for example , on the sleeping frame of a door or window.

The strike has an opening through which the roller of the compass arm can escape for full opening of the door or window.

Furthermore, at its opposite end, the compass arm is rotatably mounted on a movable assembly mounted in translation on a second support plate.

This mobile assembly is capable of occupying at least two extreme positions: a first in which the roller at the end of the arm is kept engaged in the keeper on the first support plate and a second position allowing, precisely, the release of this waste .

This moving assembly can be pushed into this second position against the action of a return spring. Key locking means are capable of preventing any displacement of this moving assembly while maintaining it in said first position, while in an unlocked position, they confer the mobility required for the release of the latch roller.

The cracking device described in this prior document, further comprises locking means in rotation of the compass arm, in the plane of the opening on which it is mounted. In a way it is a means of locking and unlocking the door.

By acting on these means, the operator can bring the opening in the cracking position. On the contrary, during closure, said means, subject to elastic reminders, automatically engage said compass arm by maintaining it in the plane of the opening and, thereby, keep the door or window closed .

If the operator now wants to fully open this door or window, it must first actuate the key member to unlock the movable assembly, it is then pushed from its first in its second position, against the action of resilient means of recall leading to the release of the roller of the compass arm of the striker on the frame. This results in the opening of this opening, opening which can be done in its entirety, the connection, through the arm of compass, between the opening and the frame being interrupted.

When closing, the cooperation of the roller of the compass arm and the striker leads to push the moving assembly from the first in the second position against the action of the elastic return means, which then cause the automatic engagement of the roller in said striker and the ascent of this movable assembly from the second position in the first position. It is then sufficient to actuate the key to annihilate the freedom of movement of the moving assembly and prevent the opening of the entire opening, only cracking is possible.

As is apparent from the foregoing description, only one key may or may not release the mobility of the moving assembly. Also, assuming that the key member is turned in its unlocked position, an operator may inadvertently push the moving assembly from its first in its second position and cause the total opening of the door or window. The risk of defenestration is not avoided.

In short, it is imperative that under no circumstances, starting from the closed position of the door or window, it can be fully open. This is to ensure that this door or window opening can be controlled only from the half-open position.

In addition, the object of the present invention is that to release the compass arm and, therefore, to be able to pass from this half-open position to the position total opening, the maneuver to be performed is not within the reach of children.

Specifically, one of the objectives of the present invention is a cracking device which requires, in any case, to go through the interlocked position to annihilate its function and allow the total opening of the opening of which it is led to limit the range of motion.

Furthermore, another object of the present invention is that the functions of the cracking device can be annihilated only with a sufficiently complex and difficult maneuver so that it is not within the reach of the most sensitive people, especially children.

For this purpose, the invention relates to a door or window cracking device comprising a compass arm whose first end is mounted to move in translation and / or in rotation on a first support plate and whose other end is movable to less in rotation on a second support plate, at least one of the ends of said arm being provided with a locking member, such as a roller cooperating with a striker equipping, as the case may be, the first and / or the second support plate, said keeper having an opening for engaging and disengaging said locking member in the striker, said crencher further being provided with locking means for preventing release of said striker locking member, on said locking means acting against manual release control means.

According to a feature of the present invention, the unlocking control means to which the blocking means preventing the release of the latch roller are associated are associated with the support plate equipped with said striker.

Advantageously, the cracking device is provided with locking means which are dependent on the unlocking control means.

In particular, said support plates comprise fastening means rabbet joinery.

The advantages deriving from the present invention are that the resulting cracking device provides a very high degree of safety.

Thus, by associating the locking means, the unlocking control means and the locking means to the support plate equipped with the striker, the operator can access it only once the door or window ajar. Moreover, the complexity conferred to the maneuver allows the execution of the latter only by an informed user.

Other objects and advantages of the present invention will become apparent from the following description relating to an exemplary embodiment given by way of indication and not limitation.

The present invention relates to a half-opening device 1 provided for maintaining in an ajar position, an opening 2 of a door or window 3, this with respect to a fixed frame 4.

This cracking device 1 comprises a compass arm 5, a first end 6 of which is visible in FIGS. Figures 1, 3 and 4 , mounted mobile in translation and in rotation on a first support plate 7. This is illustrated in the figure 1 , taking position in rabbet 8 of the lower cross member 9 of the fixed frame 4.

This sliding and rotatable mounting of this first end 6 of the compass arm 5 on this first support plate 7 can be done in the manner of a buttonhole, said first support plate 7 having a longitudinal oblong slot 10 along which can slide a tip 11 of T-structure or equivalent.

As it is illustrated more particularly on the figure 3 this support plate 7 may be provided with elastic return means 12, in particular in the form of a helical spring or the like, tending to pull the compass arm 5 in a retracted position along the oblong slot 10 corresponding to the occupied position by said compass arm 5 when the door or window 3 is closed. The interest of such means will appear further in the description.

As for the other end 13 of the compass arm 5, it is provided with a locking member 14 in the form of a roller the embodiment of which is illustrated in the figures, cooperating with a keeper 15 which equips a second support plate 16 which, in the illustrated embodiment, is fixed in rebate 17 of the opening 2.

The keeper 15 has an opening 18 through which the locking member 14 at the end 13 of the compass arm 5 can escape.

It should be noted, in this connection, that the cracking device 1 comprises locking means 18 to prevent this release of the locking member 14 of the striker 15. Substantially, such locking means 18 are in the form of means shutter-type shutter 20 closing, in their active position, at least partially the opening 18.

According to a preferred embodiment visible on the Figures 5 and 6 , said closure means 20 are in the form of a lever 21 pivotally mounted on the second support plate 16, this lever 21 being able to occupy a first locking position 22 in which, precisely, it extends at least partially in front of the opening 18 to prevent the removal of the locking member 14 when engaged in the striker 15. This lever 21 can still occupy at least a second unlocking position 23 in which it can be pushed back, especially manually, to, on the contrary, release the arm of compass 5 and allow the total opening of the door or window. Preferably, this lever 21 can still be pushed into this second unlocking position 23, starting from the first locking position 22, under the action of the locking member 14 in this case the roller, seeking to regain the strike 15. This will be particularly the case when, after a total opening of the opening 2 of a door or window, it is closed by recalling, that before the elastic return means 12 have necessarily pushed the arm of compass 5 in its retracted position so that at the time of closing of the opening, said locking member this compass arm is positioned to the right of the said keeper 15.

Preferably, moreover, the elastic return means 12 not only push back the compass arm 5 to its retracted position, which is the one corresponding to the closed door or window, but, in addition, brings it back from its position. in the alignment of the support plate 7, or in a plane parallel to the plane of the frame 4. In short, the cracking device comprises elastic return means 12 of the compass arm in a plane parallel to that of carpentry. Thus, at the time of closure of the opening 2 the locking member 14, which is provided at the end 13 the compass arm 5, is necessarily at the right of the striker 15, in which it is possible to engage automatically pushing the lever 21 in said second unlocking position 23.

Particularly advantageously, the lever 21 is still subjected to elastic return means 24 ensuring its return to its first locking position 22. Thus, after a total opening of the opening 2 and at the time of closing of the latter, the roller 14 pushes the lever 21 against the action of these elastic return means 24 to penetrate the striker 15. Once engaged in the latter the action on the lever 21 is released allowing it to regain its first position. blocking 22 under the impetus of the elastic return means 24. These take the form of a helical spring 25 taking position in a housing 26 adapted in the second support plate 16. This spring 25 is interposed between, at a first end, the lever 21 and, at its opposite end, the bottom of the housing 26. It is preferably prestressed when said lever 21 is in its first locking position 22.

The cracking device 1 further comprises unlocking control means 27 under the impetus of which the locking means 19 can be pushed back into the unlocking position 23 to deliberately release the locking member 14 of the keeper 15.

According to the illustrated embodiment, said unlocking control means 27 are in the form of a latch 28 on one end of which can act a user by means of a handle 29 knowing that at its opposite end this latch 28 cooperates with the lever 21, in particular through a pulling tab 30 that hooks on a catch tongue 31 that this lever 21 comprises.

Preferably, the latch 28 is movably mounted on the second support plate 16 in a longitudinal direction, or substantially parallel to the plane of the door or window. This longitudinal direction is marked D in the figures.

So that it is not possible to make the cracking device 1 inoperable too easily, it is still equipped with locking means 32 with manual unlocking control acting on the unlocking control means 27. In short, it is is that by bringing the locking means 32 into their unlocked position, the unlocking control means 27 are released to precisely enable them, in turn, to act on the locking means 19.

According to an advantageous embodiment, the locking means 32 are in the form of a pusher 33 capable of being, as the case may be, pulled or pushed back from a locking position of said unlocking control means 27 towards a unlocking position against the action of elastic return means 34.

Thus, in the embodiment particularly visible in the figures of the accompanying drawings, by pushing the pusher 33 from its locking position towards the unlocking position, this results in the release of a retaining tab 35 that includes this pusher 33 with respect to a recess 36 in which it was previously inserted in the rest position, so that locking. This results in the mobility of the latch 28 which can then be pulled, by means of its gripping handle 29, to rotate the lever 21 from its first locking position 22 to its unlocking position 23.

Preferably, the pusher 33 acts in a direction d perpendicular to the direction of displacement D of the latch 28.

In sum, it is necessary, at first, to push the pusher 33 to provide the unlocking function of the locking means 32. Then it is necessary to pull the latch 28 through the handle 29 to allow the release of the organ locking 14 of the compass arm 5 of its keeper 15 and control the opening of the opening 2.

It should be noted that at this moment the elastic return means 12 are used, bringing along the oblong slot 10, the compass arm 5 in its retracted position, preferably in the longitudinal axis of the first patina 7, position normally occupied by the compass arm 5 when the door or window 3 is closed.

As already indicated above, the re-engagement of the locking member 14 in the striker 15 thus occurs automatically to the closure of the opening 2 on the frame 4 rendering systematically active again. cracking device 1.

Complementarily, it also comprises means for retaining the compass arm 5 in its half-open position. Such means 37 are essentially to prevent the opening 3 is closed freely when it is brought into its interlocked position.

Preferably, such retaining means 37 are in the form of resistance means to the rotation of the compass arm 5 on the second support plate 16 equipped with the striker 15, substantially when it reaches its half-open position relative to to the latter and / or approaching this half-open position.

According to a preferred embodiment, near its end 6, this compass arm 5 comprises a boss or lug or equivalent 38 coming into opposition with a ramp 39 that includes the second support plate 16 equipped with the keeper 15, precisely when the compass arm 5 reaches this half-open position or approaches it. At this moment, this arm 5 then deforms slightly to allow the crossing of the means 38 and 39 ensuring its maintenance in the half-open position.

According to an advantageous embodiment, the second support plate 16, equipped with the striker 15, is defined in the form of a housing 40 serving as a housing, not only for the striker 15, but also for the locking means 19 and the means of release control 27, and the locking means 32, this housing 40 receiving a cover 41 protecting the various parts. Through the cover 41, however, remain accessible the striker 15 the pusher 33, as well as the handle 29 of the latch 28.
