Description

Description

Title of the invention: Closure or concealment device with apron and burglar-resistant system The present invention relates to a closure or concealment device for a construction.

This invention relates to the field of building and, more particularly, to the field of manufacturing devices designed to close an opening that includes a construction or designed to obscure a room of such a construction. In fact, this invention will find a particularly suitable application in the context of a garage door or a roller shutter without the present invention being in any way limited thereto.

We already know closing devices constituted by a garage door. Such a closure device comprises a garage door leaf capable of closing such a garage. Such an apron has at least a portion in the form of a rigid panel, and switches between a closed position and an open position of the garage. This closing device also comprises lateral slides which are made integral with the masonry, and inside which rollers move, which are fitted, laterally, at one end (notably lower) of the deck. This closing device also includes a compass system, which connects the deck to the masonry, and which guides this deck during the opening and closing maneuvers. Such a closing device has drawbacks, in particular as regards the security of the garage closed by this closing device. Indeed, an attempted break-in, which consists in exerting an action under the apron, has the effect of causing the lifting of this apron which tilts and thus allows the opening of the garage.

We also know of blackout devices consisting of a roller shutter, which completes a door, a window, a French window or the like, and which allows to hide the interior of a room or at least in part to darken the interior of such a room. Such a concealment device comprises a roller shutter curtain which comprises a plurality of portions which are articulated two by two, one of which is a final portion. These deck portions are each made up of a rolling shutter deck blade. This concealment device further comprises, on the one hand, a winding tube on which are wound and from which the blades of the deck are unwound and, on the other hand, means for driving this tube d 'winding.

Such an apron may include portions in the form of perforated blades which allow this apron to be closed on apertures, that is to say so that it has apertures in order to allow the light to enter inside. of the room. In this closed position on openings, the blades are movable relative to each other which allows, during an attempted break-in and under the effect of an action exerted under the final blade of the deck, to lift this apron sufficiently to allow a person to enter the interior of the room.

Such a concealment device can also include an anti-intrusion system which comprises at least one connection means for connecting the apron to the winding tube. During an attempted break-in and under the effect of an action exerted under the final blade, this connection means adopts a particular configuration which ensures the blocking of the deck and prevents this deck from going up. This burglar-proof system has, however, many drawbacks. In particular, this anti-intrusion system is inoperative when the apron is closed on openwork or when this apron is partially closed.

The present invention seeks to remedy the drawbacks of closing or concealment devices of the state of the art.

To this end, the invention relates to a closure or concealment device for a construction. This device comprises, on the one hand, an apron and, on the other hand, an anti-intrusion system which comprises:

- A locking means, which comprises the apron, which is movable in displacement relative to this apron, this between an inactive blocking position and an active blocking position;

- At least one additional blocking means, which comprises the apron, which is movable in displacement relative to this apron, and which, in the active blocking position of said blocking means, cooperates with this blocking means and adopts a active blocking position;

- an actuating means, which comprises the apron, and which is for actuating the displacement of the blocking means from the inactive blocking position to the active blocking position, this in the event of a break-in;

- At least one immobilization means, which comprises the apron, which is movable in displacement relative to this apron, which is integral in displacement of said at least one additional blocking means, and which, in the active blocking position of said blocking means, adopts an active immobilization position;

- At least one additional immobilization means, which is intended to be fixedly secured to the construction, and which cooperates, each, with said at least one immobilization means.

Another characteristic relates to the fact that the deck has an internal cavity inside which are housed at least said blocking means and said at least one additional blocking means.

Yet another feature is that this closure or concealment device comprises an elastic member, which comprises the locking means, which is fixedly secured to the deck, and which cooperates with the actuating means, this for actuate the movement of this locking means and / or of this actuating means.

An additional feature relates to the fact that the closure or concealment device comprises a wheel, which is movable in rotation about an axis as well as with respect to the deck, and which comprises said at least one additional locking means .

Yet another characteristic relates to the fact that the closure or concealment device comprises a roller, which is movable in rotation about an axis as well as with respect to the deck, and which comprises said at least one means of immobilization.

An additional feature is that the closure or concealment device comprises at least one rack which comprises said at least one additional immobilization means.

Yet another feature is that the closure or concealment device comprises at least one slide, which is intended to be fixedly secured to the construction, and inside which is located said at least one immobilization means and / or said at least one additional immobilization means.

Finally, the closure or concealment device comprises, on the one hand, a feeler bar which constitutes at least partially the actuating means and, on the other hand, means for mounting in displacement of this bar feeler relative to the apron, more particularly on this apron.

Thus, the closure or concealment device according to the invention comprises an anti-intrusion system. The presence of such an anti-intrusion system advantageously allows, and during an attempted intrusion consisting in exerting an action under the apron of this closing or concealment device (in particular under a final portion of this apron) , to immobilize this apron and to prevent the rise of this apron.

In this closure or concealment device, on the one hand, the apron (in particular the lower part of this apron, a final section of this apron or a final blade of this apron) comprises said locking means, said at least one additional blocking means and said at least one means for immobilizing the anti-intrusion system and, on the other hand, said at least one additional immobilizing means is fixedly secured to the construction. This allows, advantageously and when an action is exerted under the apron of the closure or concealment device, to actuate the movement of the locking means (via the actuating means) which passes from the inactive position of blocking in the active blocking position in which this blocking means cooperates with said at least one additional blocking means which adopts an active blocking position. Said at least one immobilization means, in engagement with said at least one additional locking means, adopts an active immobilization position. By the cooperation of said at least one immobilization means with said at least one additional immobilization means, this active immobilization position makes it possible to immediately immobilize this deck. In addition and advantageously, such an immobilization of the apron can be ensured whatever the position (complete closing, partial closing) of this apron and whatever its configuration (in particular when closing on openwork).

The present invention relates to the field of building and, more particularly, the field of manufacturing designed devices, either to close an opening that includes a construction, or to obscure the interior of a room that includes such a construction or to at least partially darken the interior of such a room.

The invention therefore relates to a closure or concealment device 1 for such a construction.

According to a first type of embodiment, this invention relates to a closing device 1, which can be constituted by a garage door, and which comprises an apron 2 (more particularly a closing apron 2) which closes an opening which comprises construction.

According to a first embodiment of this first type of embodiment, this closure device 1 is constituted by a garage door of the tilting type. Such a closing device 1 then comprises an apron 2 (more particularly a closing apron) which takes the form of a rigid panel which switches between an open position and a closed position of the construction opening . This deck 2 has a lower part (in particular a lower end) which is intended to be positioned near a threshold of the opening of the construction (or even in abutment against this threshold), this in the closed position of the device. closing 1.

According to a second embodiment of this first embodiment, this closing device 1 is constituted by a sectional type garage door. Such a closing device 1 then comprises an apron 2 (more particularly a closing apron) which comprises a plurality of portions (20; 20 ') articulated two by two by means of articulation means 21. Each of these portions (20; 20 ') is then usually called section. This deck 2 comprises, in particular, a final portion 20 (usually called final section) intended to come to be positioned near a threshold of the opening of the construction (or even in abutment against this threshold), this in the closed position. of this closing device 1.

According to a second type of embodiment, the invention relates to a concealment device 1 which can be constituted by a rolling shutter which completes a door, a window, a French window or the like which closes an opening which the construction comprises. .

Such a concealment device 1 then comprises an apron 2 (more particularly a concealment apron) which obscures or darkens the interior of a room of this construction. This deck 2 comprises a plurality of portions (20; 20 ') articulated two by two by means of articulation means 21. Each of these portions (20; 20') is, in fact, constituted by a deck blade roller shutter. This deck 2 includes, in particular, a final portion 20 (usually called the final blade) intended to come to be positioned near a threshold of the opening of the construction (or even in abutment against this threshold), this in the closed position. of this concealment device 2.

Whatever the type of embodiment, the apron 2 (depending on the closure or concealment) may include at least one internal cavity 22.

In this regard, it will be observed that it is, more particularly, the lower part of the rigid panel or the final portion 20 (in particular the final section 20 or the final blade

20) of the deck 2 which then comprises such an internal cavity 22.

Such an internal cavity 22 extends over at least part of the length of the deck 2 (more particularly the length of the lower part of the rigid panel or of the final portion 20 of this deck 2) and / or opens out laterally with respect to this deck 2.

According to the invention, the closure or concealment device 2 comprises at least one burglar-proof system 3.

In this regard, it will be observed that it is, in fact, the deck 2 of this closing or concealment device 1 (more particularly the lower part of the rigid panel of this deck 2 or the final portion 20, in particular the final section 20 or the final blade 20, of this deck 2) which then comprises at least part of such an anti-intrusion system 3.

Anyway, such an anti-intrusion system 3 includes a locking means 4, which comprises the deck 2, and which is movable in movement relative to this deck 2, this between an inactive locking position (Figures 2 to 4) and an active blocking position (Figures 5 to 7).

Such an anti-intrusion system 3 also includes at least one additional locking means 5, which comprises the deck 2, which is movable in movement relative to this deck 2, and which, in the active locking position of said locking means 4 (Figures 5 to 7), cooperates with this locking means 4 and adopts an active locking position.

Such an anti-intrusion system 3 also includes an actuating means 6, which comprises the apron 2, and which is for actuating the movement of the locking means 4 from the inactive locking position (Figures 2 to 4 ) in the active locking position (Figures 5 to 7), this in the event of a break-in.

Such an anti-intrusion system 3 further comprises at least one immobilization means 7, which comprises the deck 2, which is movable in movement relative to this deck 2, which is integral in movement of said at least an additional locking means 5, and which, in the active locking position of said locking means 4, adopts an active immobilization position (FIGS. 5 to 7).

Finally, such an anti-intrusion system 3 comprises at least one additional immobilization means 8, which is intended to be fixedly secured to the construction (more particularly to the masonry of this construction), and which cooperates, each , with said at least one immobilizing means 7.

As mentioned above, the deck 2 (more particularly the lower part of the rigid panel of this deck 2 or the final portion 20, in particular the final section 20 or the final blade 20, of this deck 2) comprises at minus one internal cavity 22.

Also and according to another characteristic, it is inside such a cavity 22 that are housed at least said locking means 4 and said at least one additional locking means 5.

On the other hand, said at least one immobilizing means 7 and / or said at least one complementary immobilizing means 8 extend outside of the deck 2 and / or laterally with respect to this deck 2.

Yet another characteristic relates to the fact that the closure or concealment device 1 (more particularly the apron 2 of this device 1) comprises an elastic member 9, which comprises the locking means 4, which is fixedly secured to the deck 2, and which cooperates with the actuating means 6, this in order to actuate the movement of this locking means 4 and / or of this actuating means 6.

In fact, the cooperation of the elastic member 9 with this actuating means 6 allows, in the event of an attempted break-in by action (lifting) exerted under the deck 2 (in particular on the actuating means 6 that includes this apron 2), to actuate the displacement of the locking means 4 from the inactive locking position (FIGS. 2 to 4) to the active locking position (FIGS. 5 to 7), this causing the deformation of this elastic member 9 which has the effect of causing the passage of the locking means 4 (which comprises this elastic member 9) from the inactive locking position (Figures 2 to 4) to the active locking position (Figures 5 to 7).

Alternatively or (and preferably) additionally, this elastic member 9 also cooperates with the actuating means 6 to actuate the movement of this actuating means 6, this after an attempted break-in and / or after the interruption of the action exerted under the apron 2. This cooperation then allows, after an attempted break-in and / or after the interruption of the action exerted under the apron 2, to this elastic member 9 of recall this actuating means 6 in its initial position (corresponding to that adopted in the absence of such an attempted break-in or such an action).

Anyway, this elastic member 9 may be constituted by an elastic rod 90 which comprises, on the one hand, a fixed end 91 which is fixedly secured to the deck 2, on the other hand, one end free 92 which cooperates with the actuating means 6 and, on the other hand, an intermediate part 93, which extends between the fixed end 91 and the free end 92, and which comprises the locking means 4.

In this regard, it will be observed that this locking means 4 is advantageously constituted by a deformation (more particularly a ripple, a bump, a lug or the like) of the elastic rod 90, more particularly of the intermediate part 93 of this elastic rod 9.

As visible in the appended figures, such an elastic member 9 is, at least in part, positioned inside said at least one internal cavity 22 that comprises the deck 2.

Another feature (particularly visible in Figures 4 and 7) relates to the fact that the rigid panel or the final portion 20 of the deck 2 has a bottom 25 which has a slot 26 through which extends at least one part of the elastic member 9, this to be made integral with the deck 2 (in particular of the rigid panel or of the final portion 20 of this deck 2) as well as to cooperate with the actuating means 6. It is also through this slot 26 that this elastic member 9 moves, in particular in the event of break-in and / or action exerted under the deck 2, this under the impulse of this actuating means 6, or even in the event of a return of this actuating means 6 by this elastic member 9.

An additional characteristic relates to the fact that the closure or concealment device 1 (more particularly its deck 2) comprises a wheel 10, which is movable in rotation about an axis as well as with respect to the deck 2, and which comprises said at least one additional blocking means 5.

As visible in the appended figures, this wheel 10 is positioned inside said at least one internal cavity 22 that comprises the deck 2.

In addition, said at least one additional locking means 5 is each formed by a notch 50 or by a tooth.

In fact, the burglar-proof system 3 comprises a plurality of complementary locking means 5 which are each constituted by such a notch 50 or by such a tooth so that said wheel 10 is constituted by a toothed wheel.

Another characteristic relates to the fact that the closure or concealment device 1 (more particularly its deck 2) comprises a roller 11, which is movable in rotation about an axis as well as with respect to the deck 2, and which comprises said at least one immobilizing means 7.

In this regard, it will be observed that said roller 11 extends laterally relative to the deck 2 and / or outside this deck 2.

In addition, the axis around which this roller 11 is movable in rotation, is monthly parallel to (or even, and preferably, coincides with) the axis around which the wheel 10 is movable in rotation.

In addition, said at least one immobilizing means 7 is each made up of a tooth 70 or a notch.

In fact, the burglar-proof system 3 comprises a plurality of immobilizing means 7 which are each constituted by such a tooth 70 or by such a notch so that said roller 11 is constituted by a toothed roller.

As mentioned above, said at least one immobilizing means 7 is integral in displacement with said at least one additional locking means 5.

In this regard, it will be observed that the closure or concealment device 1 (more particularly its apron 2) comprises a drive shaft 12 which is integral in displacement of said at least one additional locking means 5 as well as said at minus a means of immobilization 7.

In fact, this transmission shaft 12 is integral in displacement (more particularly in rotation) with the wheel 10 (which comprises said at least one additional locking means 5) as well as with the roller 11 (which comprises said at least one means of immobilization 7).

This drive shaft 12 is movable in rotation about an axis as well as with respect to the deck 2.

In addition, the axis around which this transmission shaft 12 is movable in rotation, is monthly parallel to (or even, and preferably, coincides with) the axis around which the wheel 10 is movable in rotation and / or the axis around which the roller 11 is movable in rotation.

Additionally, the closure or concealment device 1 (in particular its apron 2) may also include a support 13 which is fixedly integral with the apron 2, more particularly with the lower part of the rigid panel or the final portion 20 (in particular of the final section 20 or of the final blade 20) of this deck 2.

According to a first embodiment, such a support 13 can be constituted by a side wall that includes the deck 2.

However and according to another embodiment illustrated in the appended figures, such a support 13 takes the form of an insert which is at least partially engaged (preferably tightly) inside the cavity internal 22 of the deck 2, more particularly at a lateral end of this deck 2.

Such a support 13 may include means 130 for receiving the elastic member 9, more particularly from the fixed end 91 of the elastic rod 90 which constitutes this elastic member 9.

Such reception means 130 can take the form of an orifice or a housing. The shape and / or dimensions, on the one hand, of such an orifice or of such a housing and, on the other hand, of the elastic member 9 (more particularly of the fixed end 91 of the elastic rod 90 of this elastic member 9) are defined to ensure a fixed mounting of this elastic member 9 (more particularly of the fixed end 91 of the elastic rod 90) on said support 13.

Alternatively or (and preferably) additionally, such a support 13 includes means 131 for receiving said at least one additional locking means 5 and / or the wheel 10 which comprises said at least one complementary locking means 5.

Again, such receiving means 131 can take the form of an orifice or a housing. The shape and / or dimensions, on the one hand, of such an orifice or of such a housing and, on the other hand, of said at least one additional locking means 5 and / or of the wheel 10 are defined for authorizing free rotation, inside this orifice or this housing, of said at least one additional locking means 5 and / or of this wheel 10.

Alternatively or (and preferably) additionally, such a support 13 comprises means 132 for receiving the transmission shaft 12.

Such reception means 132 can, here too, take the form of an orifice or a housing. The shape and / or dimensions, on the one hand, of such an orifice or of such a housing and, on the other hand, of the transmission shaft 12 are defined to allow free rotation of said transmission shaft 12 inside this orifice or this housing.

In this regard, it will be observed that such a support 13 adopts, then, more particularly, the shape of a bearing configured for the reception in rotation of said transmission shaft.

12.

Another characteristic relates to the fact that, on the one hand, the means of reception 131 of said at least one additional locking means 5 and / or of the wheel 10 and, on the other hand, the means of reception 132 of the transmission shaft 12 extend, each along an axis, these axes preferably being combined.

Yet another characteristic is that the closure or concealment device 1 comprises at least one rack 14 which comprises said at least one additional immobilization means 8.

Such a rack 14 is intended to be made integral with the construction, more particularly with the masonry of this construction.

Regarding said at least one additional immobilization means 8, it is each constituted by a notch, by an opening 80 (in particular by a cutout) or by a tooth.

Thus, when said at least one immobilization means 7 is each made up of a tooth 70, respectively by a notch, said at least one additional immobilization means 8 is then each made up of a notch, by an opening 80 (in particular by a cutout) or by a tooth, respectively by a tooth.

An additional characteristic relates to the fact that the closure or concealment device 1 also comprises at least one slide (not shown), which is intended to be fixedly secured to the construction (more particularly to the masonry of this construction), and inside which is located said at least one immobilization means 7 and / or said at least one complementary immobilization means 8.

It is, more particularly, inside such a slide that moves said at least one immobilizing means 7 and / or the roller 11 which comprises said at least one immobilizing means 7.

It is also, inside such a slide that is implanted (e) said at least one additional immobilization means 8 and / or the rack 14 which comprises said at least one means of additional fixed assets 8.

Additionally, the lateral end of the apron 2 can also be located (in particular in a mobile manner) inside such a slide.

As mentioned above, the closure or concealment device 1 comprises an actuating means 6.

In this regard, it will be observed that this closure or concealment device 1 (more particularly its apron 2) comprises, then, on the one hand, a feeler bar 15 which constitutes at least in part the actuating means 6 and, on the other hand, displacement mounting means 16 of this feeler bar 15 relative to the deck 2.

In fact, such displacement mounting means 16 are, more particularly, configured to ensure mounting in displacement of this feeler bar 15 on this deck 2, more particularly on the final portion 20 (final section or final blade) of this apron 2.

In addition, such displacement mounting means 16 are configured to allow movement of this feeler bar 15 in a direction parallel to a plane along which extends the rigid panel or the final portion 20 (in particular the final section 20 or the final blade 20) of the deck 2 and / or in a direction perpendicular to a longitudinal edge that comprises the lower part of this rigid panel or this final portion 20, more particularly that comprises the lower end of this lower part of the panel rigid or this final portion 20.

As visible in the appended figures, this feeler bar 15 takes the form of a blade 150 which has two longitudinal edges 151 each equipped with a return 152. As shown in Figures 4 and 7 , the rigid panel or the final portion 20 then comprises two parallel longitudinal walls 23 which each have, near its free end, a groove 24 for reception, so as to move freely inside such a groove 24, of a return 152 of the feeler bar 15. The displacement mounting means 16 are then constituted by the returns 152 of the feeler bar 15 and by the grooves 24 of the rigid panel or of the final portion 20.

Finally, the closure or concealment device 1 comprises drive means 17 of the deck 2, these drive means 17 being configured to drive said deck 2 in movement, this between said open position and said closed or concealed position.

According to a preferred embodiment, these drive means 17 are of the motorized type.

In fact, it is, more particularly, the deck 2 of this closure or concealment device which includes such drive means 17.

In this regard, it will be observed that these motorized drive means 17 are, at least in part, housed inside the internal cavity 22 that comprises the deck 2.

Such motorized drive means 17 include a motor 170 which is located inside the cavity 22 of the deck 2, more particularly inside the internal cavity 22 that includes the rigid panel or the final portion 20 (in particular the final section 20 or the final blade 20) of this deck 2.

Such a motor 170 comprises, on the one hand, a stator fixedly fixedly attached to the bulkhead 2 (more particularly of the rigid panel or of the final portion 20) and, on the other hand, a rotor movable in rotation relative to the stator, more particularly inside this stator.

These motorized drive means 17 further comprise a transmission shaft 171 which is engaged with the motor 170 (more particularly with the rotor of this motor 170), this directly or indirectly.

Thus and according to a preferred embodiment illustrated in the appended figures, the motorized drive means 17 further comprise a gear train 172 which comprises, on the one hand, a first gear which is integral in rotation of the rotor of the motor 170 and, on the other hand, a second gear, which is integral in rotation with the transmission shaft 171, and which is meshed with the first gear, this for a transmission shaft 171 in indirect engagement with the engine 170.

As can be seen in the appended figures, this transmission shaft 171 is engaged or (and preferably) coincides with the transmission shaft 12 mentioned above.

This transmission shaft 171 is therefore engaged with said at least one immobilization means 8, more particularly with the roller 11 which comprises said at least one immobilization means 8. This advantageously allows the means of motorized drive 17 to drive said at least one immobilization means 8 and / or the roller 11 (which comprises said at least one immobilization means 8), this to ensure the drive of the deck 2 and, therefore, its movement between open and closed positions.
