Abstract

The anti-forcing device comprises a locking mechanism (9) able to lock in translation the bolt operating rods when the door is in any open position. The locking mechanism consist of a locking peg (11) which extends perpendicularly behind the operating rod and engages an opening in the rod under the pressure of a spring (13). It also has unlocking mechanism (10) which deactivate the locking mechanism once the door is closed in its frame. These mechanism comprise a control peg (19) extending from the locking peg which passes through a slot in the operating rod and projects into the rabbet.

Description

The invention relates to an anti-false operation device for door, window or the like equipped with a lever or lever-bolt.

The present invention will find its application in the field of the building hardware.

We already know a number of devices anti-false maneuver corresponding to the description above and having the function of preventing a locking fitting of the cremone bolt or bolt lock type, fitted to a door, window or the like, can be manipulated, as long as the opening of this door or other has not been previously closed on its frame sleeping.

It will be observed, in fact, that such manipulation, if it was permitted, could lead to the deterioration of this locking fitting, especially if at the time of close the door on the frame, the lock can not match their strike.

The consequences can be even more serious in the case of a tilt-and-turn window. Indeed, if, therefore from an open position by folding down, the fitting of locking is manipulated to lead to an opening of swinging type of the sash, before it has been closed on its sleeping frame, this opening is placed in a so-called flag position, which can cause a drop of this opening of its sleeping frame.

Thus, an anti-counterfeit device is particularly known. operation in the form of a lever mounted tilting in rebate of the opening, this lever being subjected to means of elastic return tending to push it towards the sleeping frame. Such a lever is mounted integral in rotation a pivot shaft coming through the headrest housing usually an operating rod corresponding to the lever or locking bolt fitted to this opening.

In fact, this shaft, driven in rotation by said lever, is provided with a retaining tab intended to cooperate with a light provided in the operating rod.

Also, at the moment when the opening comes to deviate from the frame the lever is pushed back towards this frame under the influence of the aforementioned elastic return means. AT this moment, the retaining tab having been driven during of this rotation of the lever, comes to position askew in a suitable opening in the operating rod. It is then impossible to transmit to the latter any movement under the impulse of the control mechanism of the cremone bolt or bolt lock.

Note that at each of the positions adopted by the rod maneuver in each of the opening possibilities of the opening (swinging or folding) corresponds to an opening in said operating rod with which is able to cooperate said retaining tab.

Such a state of the art corresponds, in particular, to the document EP-A-0.735.223. In this case the lever fills, also, another function. Indeed, it intervenes, in combination with a support stop on the frame, in as a device for lifting the sash. In fact, such device has a very particular utility in the case large openings.

Document DE-29.18274 also discloses a device anti-misuse for cremone bolt in the form of a housing provided capable of taking position in a groove of joinery rebate. More particularly, this case extends to the back of a headrest which it is made integral and which shelters, moreover, a maneuvering rod provided able to move longitudinally, between a locking position and unlocking, under the action of a control mechanism appropriate.

In addition, said housing contains a locking finger to displacement perpendicular to the axis of said rod maneuver or the headrest, this locking finger being pushed back into the active blocking position under the impulse of a spring formed at the bottom of the case.

More particularly, the locking finger is brought to cooperate with an accessory piece attached to the back of the rod operating and defining, under the latter, two stops transverse between which said finger is pushed blocking to immobilize the movement of said rod operation, once the opening of the carpentry.

As for the unlocking means, they are defined, on the one hand, by a tab extending above the locking finger substantially in the median plane of the rod which also includes a light allowing the passage of this tab. It crosses, again, a appropriate opening in the headrest to come and present prominent compared to the latter. On this end protruding tongue is attached a control button on which is able to act an actuator placed in rebate of the dormant. More specifically, when closing the door on the frame, the actuator acting like a cam, pushes the tab through the control button inside the case corresponding to the anti-counterfeit device maneuver. This action is reflected on the finger of blockage coming out between the transverse stops for allow, finally, the displacement of the rod maneuver corresponding to the lever.

In view of the above description, it should be concluded that the solution proposed in this document DE-29 18 274, requires the addition of an additional room at the back of the operating rod to allow the blocking of this last in the opening position of the opening. In addition, a such solution leads to a significant increase in the housing depth requiring additional notching carpentry.

It will also be noted that this state of the art does not offers no solution to make the anti-tampering device.

Thus, the invention relates to an anti-forgery device operation for door, window or the like equipped with a cremone bolt or lock-bolt comprising a central box accommodating a mechanism for the movement control of at least one operating rod extending above and / or below the housing, said device comprising, on the one hand, means of blocking designed capable of blocking in translation the operating rods when the opening of said door, window or the like, is in any of its positions opening and, on the other hand, release means provided to deactivate said blocking means when closing opening it on its sleeping frame, these blocking means consisting of a locking finger taking position in a housing, so, on the one hand to extend perpendicularly at the rear of an operating rod and, on the other hand, cooperate, under the impulse of elastic return means, with one or more openings in this operating rod of section adjusted to that of said locking finger, the means of release being defined, on the one hand, by a control finger extending said blocking finger and coming through a light adapted in the operating rod so as to be present protruding rebate of the opening and, on the other hand, by an actuator secured to the sleeping frame or opening it so as to repel, by acting on the part protruding from the control finger, the locking finger in a clear position of the operating rod. More in particular, this device includes means provided able to make it inactive.

It will already be observed that the present invention extends, also in the case corresponding to a door, window with two leaves, one of which is fitted with a the other acting as a sleeping frame. In particular, the anti-misuse device is capable of release the operating rod from the locking fitting equipping the other leaf this when folding the latter on the leaf previously quoted.

The advantages resulting from the present invention consist, basically in that the anti-fake device maneuver, through its design particularly simplified, is able to be integrated directly, with parts of a locking fitting. Especially this anti-tampering device can take position in the central case of a lever or lever-bolt which facilitates, of course, the assembly operations of this last.

Note that, under such conditions, such a device anti-misuse can simultaneously fulfill the functions of a temporary immobilization device of the operating rods to facilitate positioning different parts corresponding to this lever or locking bolt when mounting the latter on a carpentry. Usually such devices fixed assets are in the form of studs breakable allowing to connect, in a determined position, an operating rod relative to its headrest, this stud being automatically sectioned during the first order of the locking fitting, either at the time of its function test.

However, as will be described later, this function temporary immobilization of the operating rod (s) can also be attributed to suitable auxiliary means.

The invention will be better understood on reading the description which follows relating to an exemplary embodiment illustrated in the attached drawing.

As illustrated in the different figures of the attached drawing, the present invention relates to an anti-forgery device operation 1 for door, window or the like, fitted a locking fitting, of the bolt type or the bolt lock 2, more particularly represented in the form of a cremone bolt in figures 1 and 4.

Such an anti-false operation device 1 has the function to prevent the said bolt or bolt lock 2 from being manipulated when the door leaf 3, window or the like is in any of its open positions. As recalled in the introductory part, such manipulations, carried out inadvertently, can lead to malfunctions in the locking fitting, or even the opening of the opening relative to the frame.

We will notice that this cremone bolt 2 or cremone bolt, has a central box 4, often embedded in rebate of the opening 3 and / or above and below which extend a or operating rods 5.

In order to fully understand the object of the present invention, the cremone bolt 2 has been illustrated, in FIGS. 1 and 4, under form of a simplified embodiment. Indeed, in his central box 4 this lever 2 accommodates, mainly, a follower 6 on which a user can act by via a handle or a control button, this follower 6 coming to mesh, through a toothing 7 appropriate, on a rack 8 directly equipping the operating rod 5. This comes, here, to extend to the times, above and below this central box 4.

To come back to the anti-false maneuver device 1, this one comprises, on the one hand, locking means 9 designed capable of block in translation the operating rod (s) 5 of this cremone bolt or bolt lock 2, this when the leaf 3 is brought into any of its open positions relative to its sleeping frame. On the other hand, it includes unlocking means 10 provided to deactivate said means of blocking 9 when closing this opening 3.

The locking means 9 consist of a locking finger 11 taking position in a case, especially the case central locking lever 4 or locking bolt 2, this so that this locking finger 11 extends perpendicularly and at the rear of the operating rod 5 in order to cooperate with one or more openings 12, 12A in the latter, driven by elastic return means 13.

More particularly and as visible in Figures 1, 2, 4 and 5, the elastic return means 13 can borrow the form of a helical spring 14 which comes between the bottom 15 of the housing 4 and a support flange 16 fitted, in its rear part, the locking finger 11. Note that in the bottom 15 of the housing 4 can be arranged a stud positioning 17 on which the spring 14 engages, while it is still guided up to the finger of blocking 11 via an annular skirt 18 extending, backwards, the support flange 16.

As for the openings 12, 12A in the operating rod 5, they are of adjusted section to allow the engagement of the locking finger 11 and prevent, under these conditions, the displacement of this operating rod 5.

Furthermore, the unlocking means 10 are defined, substantially, on the one hand, by a control finger 19 extending said locking finger 11 while presenting a section 20 weaker than that of the latter. This finger of command 19 thus comes through a light 22 adapted in the operating rod 5 and appear protruding in the rebate opening 3.

When it comes to a suitable light 22 in the rod maneuver 5, this light 22 extends longitudinally in the latter and has a width 23 slightly greater than section 20 of the control finger 19, while being less than the section 21 of the locking finger 11.

Furthermore, as defined above, the control finger 19 must be able to appear prominent in rebate of the opening 3. Also, assuming that the operating rod 5 is sheltered, at the level of this rebate of the opening 3 by a headrest 24, as shown in the figures, account is taken of the excess thickness produced by this last for the dimensioning of said control finger 19.

The unlocking means 10 are further defined, on the other hand, by an actuator 25 provided capable of repelling, by action on the projection 26 of the control finger 19, the blocking 11 in a position as visible in the figures 4 to 6, i.e. released from the operating rod 5 against the action of the elastic return means 13. This actuator 25 intervenes, of course, when closing the opening 3 on its sleeping frame.

Ultimately, the stroke 27 communicated by the actuator 25 the control finger 19 must be sufficient to cause the release of the locking pin 11 from the opening 12 or 12A in which he was previously engaged, authorizing, then the free movement of the operating rod 5 therefore of the finger control 19 in the light 22 arranged longitudinally in the latter.

To better understand the object of the present invention, we refer, in particular, to FIG. 3 where we see, in section, the locking finger 11 engaged in an opening 12 of the operating rod 5 while in the representation corresponding to FIG. 6 only the control finger 19 is visible in section, because only he is still engaged, at this time there, in the light 22 of the operating rod 5.

As for the actuator 5, it can be in the form of a single keeper with fixed ramp, in correspondence, in rebate of sleeping frame, this in order to push back the control finger 19 and therefore the locking finger 11 in its housing 4 at the time to close the door 3.

Of course, when it comes to the frame, it can be defined, in part, by an amount from another leaf corresponding to the door, window or the like.

As shown in Figures 1 and 4, the actuator 25 can still be associated with the opening 3 itself and appear under form of a lever 28 mounted tilting about an axis 29 parallel to the plane of this opening 3, this in rebate of this latest. This lever 28 is then subjected to return means elastic 30 tending to push it back into a position waiting, towards the sleeping frame, while, in its lower part 31, it is provided with a cam 32 capable to act on the projecting part 26 of the control finger 19.

Thus, when removing the opening from its sleeping frame, the elastic return means 30, acting on the lever 28, push it back towards the said frame in its waiting position. The cam 32 then being in the impossibility of acting on the control finger 19, it the engagement of the locking finger 11 corresponding to the anti-false operation device 1 in an opening 12, 12A of the operating rod 5 to immobilize it in translation.

In contrast, by closing the opening 3, the sleeping frame acts on lever 28. At this time, it is brought back into the substantially extending said operating rod 5, against the action of the elastic return means 30, bringing the cam 32 to push back, again, said control finger 19 which reflects its movement on the locking finger 11 releasing, at the same time, said operating rod 5.

As is apparent from the foregoing description, the present invention relates to a device for anti-false operation 1 of particularly simplified design so it can take a stand, in particular, in the case center of a locking fitting, of the bolt type or lock-bolt.

Another advantage is that by equipping a cremone bolt or cremone bolt, of such an anti-false operation device 1, in accordance with the invention, there is no need to call on a temporary blocking device, as done usually to immobilize in translation a rod of maneuver the time required to install the cremone bolt or lock-bolt on a carpentry and, in particular for facilitate the cutting of these rods during this installation.

However, as already explained in the section introductory, this temporary blocking function can still be allocated to suitable auxiliary means associated with this anti-misuse device 1. Such means can be present, for example, in the form of one or more lobes breakable (not shown) extending, in a way, the locking finger 11 in the direction of the operating rod 5 and therefore of the headrest 24. By resting on the latter such lobes therefore hold the locking finger 11 erased relative to the rod 5, while ensuring immobilization of the latter, coming to take a stand in the opening 12 of this operating rod 5. At the first order of the lever or lever-bolt, these lobes are automatically sectioned by the action of the rod operation 5.

Finally, it was noted that it might be advisable to ability to make such an anti-misuse device inoperative, the time required to make adjustments by example, or to facilitate certain interventions, including any repair. For this purpose, the device can receive means for holding the locking finger 11 in a retracted position, erased relative to the rod 5 against the action of the spring 14. Such means can borrow a configuration similar to the system of fixing a light bulb, gag type, in a socket.

In particular, these means will be associated with the circular skirt 18 and the walls 33 of the housing accommodating said device.

However, as can be seen in FIG. 7, the locking finger 11 can still be in the form of a retaining tab 34 of rectangular section of length 35 adjusted to section 36 of the opening 12, 12A in the operating rod 5, while its width 37 is then defined less than the width 23 of the light 22. Furthermore, this blocking finger 11 is defined able to pivot around its axis, while the finger command 19 receives, in particular at the level of its part protruding 26, means allowing its grip for its rotation control.

It is thus possible to make the anti-fake device inactive operation 1 by pivoting the locking finger 11 for the position in the axis of the light 22, as shown in broken lines in Figure 7 or, on the contrary, make it active by turning this blocking finger 11 to that he can no longer move in this light 22 of the operating rod 5.

The means for gripping the control finger 19 may adopt different embodiments. In particular, in the end of this control finger 19 can be provided with accommodation for the reception of a hexagon key, or even a simple slot to accommodate a screwdriver.
