Description

1i 2786525 The invention relates to an anti-misuse device

  for door, window or the like, fitted with a cremone bolt or cremone bolt

  lock comprising a central housing 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, suitable blocking means to block in translation the operating rod or rods when the leaf of said door, window or the like is in any one of its open positions and, on the other hand, release means provided for deactivating said means of

  blocking when closing the door on its sleeping frame.

  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 cremone bolt type, equipping a door, window or the like, from being manipulated, as long as the opening of this door

  or other has not been previously closed on its sleeping frame.

  It will be observed, in fact, that such manipulation, if it was authorized, could lead to the deterioration of this locking fitting, in particular if, when closing the opening on the frame, the locking members born

can match their waste.

  The consequences can be even more serious in the case of a tilt-and-turn window. Indeed, if, starting from an opening position by folding down, the locking fitting is manipulated to lead to an opening of the oscillating type of the opening, before the latter has been closed on its sleeping frame, this opening comes to put itself in a so-called feathered position, which can cause this sash to unhook

its sleeping frame.

  Thus, an anti-device is particularly known.

  false operation in the form of a lever mounted tilting in the rebate of the opening, this lever being subjected to means of

2,278,625

  elastic return tending to push it back towards the frame. Such a lever is mounted for rotation with a pivoting shaft coming through the headrest usually housing an operating rod corresponding to the lever or lever-bolt equipping 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, when the opening comes to move away from the sleeping frame, the lever is pushed back towards this sleeping frame under the influence of the above-mentioned elastic return means. At this instant, the retaining tab having been driven during this rotation of the lever, comes to be positioned at an angle in a suitable opening in the operating rod. It is then impossible to transmit to the latter any movement under the impulse of the drive mechanism of the cremone bolt

or lock-bolt.

  Note that each of the positions adopted by the operating rod 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 with said

retaining tab.

  Such a state of the art corresponds, in particular, to document EP-A0,735,223. In this case the lever also fulfills another function. Indeed, it intervenes, in combination with a bearing abutment on the sleeping frame, as a device for lifting the opening. In fact, such a device has a very particular utility in the case of large openings. It is also known, through document FR-A-2,756,863, another safety device, of the anti-tampering type, capable of preventing the operation of a locking fitting upon opening.

  a door leaf, window or the like.

  This device comprises, on the one hand, a support in the form of a box capable of being attached to the surface on a headrest provided

3,2786525

  in the rebate of this leaf and, on the other hand, a locking finger passing through this headrest under the impulse of elastic return means in order to block in translation an operating rod corresponding to said locking fitting and coming to move at the back of the aforementioned headrest. In fact, the cooperation between the locking finger and the operating rod occurs more particularly when the door or window is open. For this, this device also receives a connecting lug which comes to fit on the locking finger through a light provided in the housing. This connecting tab is extended by an operating tab defining a control member on which is able to act, either another leaf, or the frame of the door, window or other, at the time, precisely, to close that -ci, in order to release, through the locking finger, the operating rod of the locking fitting. This can, therefore, be operated, freely to be brought into any position, for example fully locked, or even in a position corresponding to another mode of opening

from said door or window.

  The major drawback of these different types of anti-tampering devices is that they are in the form of a member independent of the locking fitting, so that they must be individually secured on a joinery , this compared to the other elements corresponding to

said locking fitting.

  It is often still necessary that said locking fitting has a headrest with respect to which an operating rod is able to be immobilized. Precisely,

  in some designs this headrest is lacking.

  Ultimately, the present invention is intended to provide an answer to the aforementioned problems through an anti-false maneuver device whose installation occurs at the same time

  time than the other components of a locking fitting.

  In particular, this anti-false operation device has a configuration allowing it to take a position in the housing.

4 2786525

  central housing the control mechanism of this locking fitting. In addition, it can be controlled by an actuator capable of borrowing different embodiments depending on whether it is made integral with the dormant frame on which the opening having the locking fitting comes to be closed or that it is mounted on opening it himself. In particular in the latter case, this actuator can take the form of a lever of a

  lifting device, as known by a person skilled in the art.

  To this end, the invention relates to an anti-false operation device for door, window or the like, equipped with a cremone bolt or cremone bolt comprising a central housing accommodating a mechanism for the movement control of at least an operating rod extending above and / or below said housing, said device comprising, on the one hand, locking means designed capable of blocking in translation the operating rod or rods when the opening of said door, window or the like is in any one of its open positions, and, on the other hand, unlocking means provided for deactivating said locking means when closing the opening on this sleeping frame, characterized by the fact that the locking means consist of a locking finger taking position in a housing, in particular in the central housing of the lever or lever-lock, so as, on the one hand, to extend, perpendicular to the back of 'an operating rod and, on the other hand, in order to cooperate, under the impulse of elastic return means, with one or more openings in this operating rod of cross section adjusted to that of said locking finger, the means of release being defined, on the one hand, by a control finger extending said locking finger and coming through a suitable light in the operating rod so as to be projecting into the rebate of the opening and, on the other hand, by an actuator made integral with the sleeping frame or with the opening so as to push back, by action on the projecting part of the control finger, the locking finger in a position released from the rod

2786525

  maneuver, against the action of elastic return means,

  moment to close the door on the frame.

  It will already be observed that the present invention extends, also to the case corresponding to a door, window with two leaves, one of which is fitted with a locking fitting, the other playing the role of sleeping frame. In particular, the anti-tampering device is capable of releasing the operating rod from the locking fitting fitted to the other leaf, this at the time of folding the latter over

the leaf previously quoted.

  The advantages resulting from the present invention consist essentially in that the anti-false operation device, through, its particularly simplified design, is able to be integrated directly, into the members of a locking fitting. In particular, this anti-misuse device can take position in the central box of a lever or lever-lock which facilitates, of course, the operations of

assembly of the latter.

  Note that, under such conditions, such an anti-false operation device can, simultaneously, fulfill the functions of a temporary immobilization device for the operating rod or rods in order to facilitate the positioning of the various corresponding parts. to this lever or lever-bolt when mounting the latter on a joinery. Usually, such temporary immobilization devices are in the form of breakable studs making it possible to connect, in a determined position, an operating rod relative to its faceplate, this stud being automatically cut off when the locking fitting is ordered for the first time. , either at the time of its

function test.

  However, as will be described later, this temporary immobilization function of the operating rod or rods can

  still be allocated to suitable auxiliary means.

  Other objects and advantages of the present invention

  will appear during the description which follows relating to

6 2786525

  to an embodiment which is given only by way of example

indicative and not limiting.

  Understanding this description will be facilitated by

  Referring to the attached drawing in which: - Figure i is a diagrammatic and sectional representation of a cremone bolt whose central housing accommodates an anti-mishandling device according to the invention, this device being shown here in a position leading to immobilize, in translation, an operating rod of this lever; - Figure 2 is a schematic representation of detail of Figure i; - Figure 3 is a schematic representation in section on III-III of Figure 2; - Figures 4, 5 and 6 correspond to representations similar to Figures 1, 2 and 3, the anti-false operation device being deactivated, corresponding to the case where the opening is closed on its sleeping frame, allowing the manipulation of the locking fitting, here shown in the form of a lever; - Figure 7 is a view similar to Figure 3, the locking finger taking the form of a retaining tab capable of pivoting to make said anti-tampering device inactive.

  As illustrated in the different figures of the drawing below

  attached, the present invention relates to a device for anti-false operation i for door, window or the like, equipped with a locking fitting, of the bolt type or the bolt lock 2, more particularly represented in the form of a bolt in the

Figures 1 and 4.

  The function of such an anti-false operation device 1 is to prevent said cremone bolt or lock bolt 2 from being able to be manipulated when the leaf 3 of the door, window or the like is in any of its positions. opening. As recalled in the introductory part, such manipulations, carried out inadvertently, can cause malfunctions at the level of

7 2786525

  the locking fitting, or even the opening of the opening

compared to the frame.

  It will be noted that this cremone bolt 2 or cremone bolt, comprises a central box 4, often embedded in the rebate of the opening leaf 3 and / or above and below which extend one or more

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, in the form of a simplified embodiment. In fact, in its central housing 4 this lever 2 receives, mainly, a follower 6 on which a user is able to act by means of a handle or a control button, this follower 6 coming from mesh, through appropriate teeth 7, on a

  rack 8 directly fitted to the operating rod 5.

  It comes, here, to extend at the same time, above and below

of this central box 4.

  To return to the anti-misuse device 1, this

  this comprises, on the one hand, blocking means 9 designed capable of blocking in translation the operating rod or rods 5 of this cremone bolt or locking bolt 2, this when the leaf 3 is brought into any one of its open positions relative to its sleeping frame. It comprises, on the other hand, unlocking means 10 provided for deactivating said locking means 9 at

moment to close this opening 3.

  In fact, according to the invention, the locking means 9 consist of a locking finger 11 taking position in a housing, in particular the central housing 4 of the lever or lever-lock 2, this in such a way that this locking finger 11 extends perpendicularly and behind the operating rod 5 in order to cooperate with one or more openings 12, 12A in this

  last, driven by elastic return means 13.

  More particularly and as visible in FIGS. 1, 2, 4 and 5, the elastic return means 13 can take the form of a helical spring 14 which comes to be interposed between the bottom 15 of the housing 4 and a support flange 16 equipping, in its part

8 2786525

  rear, the locking finger 11. Note that in the bottom 15 of the housing 4 can be arranged a positioning pad 17 on which the spring 14 engages, while the latter is still guided at the level of the locking finger 11 by means of an annular skirt 18 extending, towards the rear, the support flange 16. As for the openings 12, 12A in the operating rod 5, they are of cross-section adjusted to allow engagement of the finger blocking 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 having a smaller section 20 than that of the latter 21. This control finger 19 thus comes through a suitable light 22 in the operating rod 5 and presents itself projecting in rebate of

opening it 3.

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

  section 21 of the locking finger 11.

  Furthermore, as defined above, the control finger 19 must be able to appear projecting into the rebate of the opening 3. Also, assuming that the operating rod 5 is sheltered, at this rebate of the opening 3 by a headrest 24, as shown in the figures, account is taken of the extra thickness produced by the latter 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 pushing back, by action on the projecting part 26 of the control finger 19, the locking finger 11 in a position as visible in the figures. 4 to 6, namely disengaged from the operating rod 5 against the action of the elastic return means 13. This actuator 25 intervenes, although

  sure, when closing the opening 3 on its sleeping frame.

9 2786525

  In the end, the stroke 27 communicated by the actuator 25 to the control finger 19 must be sufficient to cause the disengagement of the locking finger 11 from the opening 12 or 12A in which it was previously engaged, thereby allowing free displacement of the operating rod 5 therefore of the control finger 19 in the slot 22 formed longitudinally in the latter. To better understand the object of the present invention, reference will be made, in particular, to FIG. 3 where we can see, in section, the locking finger 11 engaged in an opening 12 of the operating rod 5 while that in the representation corresponding to FIG. 6 only the control finger 19 is visible in section, because only it is still engaged, at this time,

  in the opening 22 of the operating rod 5.

  As for the actuator 5, it can be in the form of a simple keeper with fixed ramp, in correspondence, in the rebate of the sleeping frame, this so as to push back the control finger 19 and therefore the locking finger 11 in its shoemaker 4 at the time of

close the door 3.

  Of course, when it comes to the sleeping frame it can be defined, in part, by an amount of another leaf

  corresponding to the door, window or the like.

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

  projection 26 of the control finger 19.

  Thus, at the time of opening the opening from its sleeping frame, the elastic return means 30, acting on the lever 28, push the latter towards said sleeping frame in its waiting position. The cam 32 then being unable 0lo 2786525 to act on the control finger 19, this results in 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 the lever 28. At this time, the latter is brought back in the extension, substantially, of said operating rod 5, against the action of the elastic return means. 30, causing the cam 32 to push back, again, said control finger 19 which reflects its movement on the locking finger 11 releasing, from

  at the same time, said operating rod 5.

  As is apparent from the foregoing description, the present

  The invention relates to an anti-false operation device 1 of particularly simplified design so that it can take position, in particular, in the central housing of a

  locking fitting, bolt type or bolt lock.

  Another advantage consists in that by equipping a cremone bolt or cremone lock, with such an anti-false maneuvering device 1, according to the invention, it is unnecessary to use a temporary blocking device, as is usually done to immobilize in translation an operating rod the time necessary for the installation of the lever or lever-lock on a carpentry and, in particular to facilitate the cross-checking of these

rods during this installation.

  However, as has already been specified in the introductory part, this temporary blocking function can also be attributed to suitable auxiliary means associated with this anti-false operation device 1. Such means can be presented, for example, under shape of one or more breakable lobes (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 maintain, consequently, the locking finger 11 erased relative to the rod 5, while ensuring the immobilization of the latter, coming to take position in the opening 12 of this operating rod 5. At the first command of the lever or lock-bolt, these lobes are automatically cut by

  the action of the operating rod 5.

  Finally, it was noted that it could be appropriate to be able to render such an anti-false operation device inoperative, the time necessary to make adjustments for example, or even in order to facilitate certain interventions, in particular any repair. . For this purpose, the device can receive means for holding the locking pin 11 in a retracted position, erased relative to the rod 5 against the action of the spring 14. Such means can take a configuration similar to the system of the fixing a light bulb,

  gag type, in a socket.

  In particular, these means will be associated with the circular skirt

  18 and to the walls 33 of the housing accommodating said device.

  However, as can be seen in FIG. 7, the locking finger 11 can also 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 lumen 22. Furthermore, this blocking finger 11 is defined capable of pivoting about its axis, while the control finger 19 receives, in particular at its protruding part 26,

  means for gripping it for its rotation control.

  It is thus possible to deactivate the anti-

  wrong operation i by pivoting the blocking finger 11 to position it in the axis of the light 22, as shown in broken lines in FIG. 7 or, on the contrary, to make it active by turning this blocking finger 11 to that he cannot

  no longer move in this light 22 of the operating rod 5.

  The means for gripping the control finger 19 can adopt different embodiments. In particular, in the end of this control finger 19 can be provided a housing for the reception of a hexagon key, or even a simple

  slot to accommodate a screwdriver.

12 2786525

  Although the invention has been described with reference to a particular embodiment, it is understood that it is in no way limited thereto and that it is possible to make various modifications to the forms, materials and combinations of these various elements, without for

  this is to depart from the framework and the spirit of the invention.
