Description

The invention relates to a motorized closure system with a pivoting or sliding leaf horizontally or vertically, in accordance with the preamble of claim 1.

The present invention relates to the field of building closure systems such as garage doors, gates, shutters, curtains or the like.

The closing systems for building type garage doors or sliding gates include, for the motorized drive of this type of opening, rack and pinion transmission systems.

More particularly, on the leaf is fixed such a rack with which engages a gear driven in rotation by an electric motor, often through a suitable gear.

It is usually through such a transmission and the engine that the opening is also maintained in the closed position. Indeed, it is usual to use an irreversible transmission system or to use an electromagnetic brake motor for this type of application.

If the motor is able to rotate the toothed wheel for driving the rack, a thrust exerted on the opening to obtain the opening is made impossible with an irreversible transmission.

If an electromagnetic brake motor is used, it is usually activated when the power supply is cut off. Thus, when the motor is no longer powered, the brake prevents rotation of the rotor and therefore of the shaft motor drive. This blockage is reflected through the gearbox on the toothed pinion acting on the rack mounted on the opening.

To complete the maintenance in the locked position of the opening, it is still common to use electromagnetic closure systems in the form of a latch pushed in the unlocked position from the engine powered by electrical energy and, conversely, recalled in the position of lock once the opening completely closed.

The problem posed by these known motorized closing systems lies in the difficulty of obtaining the opening of this opening in the event of engine failure or, quite simply, mains failure.

Indeed, the solution is usually to perform a disengagement operation of the motor and, optionally, to perform manual unlocking auxiliary closing systems, electromagnetic lock type or similar.

It is understood that these manual release and unlocking maneuvers are only possible from inside the house.

Also, either there is another access door to go to this house and ensure, thus, the opening of the opening from the inside, or it is provided at the level of this opening, in this case when it is about garage doors, a gate whose opening can be obtained via a conventional closing system type lock fitting.

However, depending on the type of opening that is mentioned, it can not be equipped systematically with such a door or, at least, not without constraint.

This is so for some gates, but also for garage doors whose opening is composed of several panels articulated relative to each other to be able to extend, in the open position, as appropriate, along the garage ceiling or a wall adjacent to the one with the opening that closed the opening.

In this case, sectional doors are usually used in the presence of this type of articulated panel opening.

Anyway, the addition of such a door has the effect of substantially increase the weight of the opening and complexity of its structure, which results, of course, a significant additional cost.

We also know from the document DE-A-195 01 624 , a roller shutter having a designed apron adapted to be wrapped around a winding tube housing a tubular motor. This winding tube comprises, at each of its ends, shaft sections mounted in free rotation in adapted openings in support cheeks. One of these axis sections, at one end of the winding tube, carries, in a radial manner, a locking lever whose angular displacement by rotation of said axle section is limited by two fixed stops on the support cheek. .

The locking lever acts via a coupling and transmission mechanism on a locking latch designed to cooperate with a blade deck when it is in the extended position.

Thus, during the drive control of the winding tube, by the tubular motor, in the direction of the folding of the deck, the resistance provided by the weight of the latter leads to exert on said tubular motor a pair having consequently its rotation in the limited range by the two stops cooperating with the locking lever.

The angular displacement imparted to the latter leads to the unblocking control of the latch acting on a blade of the deck.

If this solution of the state of the art has the advantage of providing an additional locking point to the deck of the shutter when it is deployed, it does not respond to the problem of the control of folding, therefore opening of this shutter rolling in engine malfunction. If one can imagine that the latch can be unlocked from inside the house and this manually, it is still necessary to ensure the disengagement of the motor that can rotate freely around its axis of drive on the range of movement of the lever locking between the two stops.

The present invention is able to respond to this difficulty. Thus, in a first inventive step, it has been imagined that apart from the opening and closing operation phases, the drive motor is disconnected from the opening so that any manipulation of this opening since the outside of the house becomes independent of the motorized drive mechanism.

In the context of a second inventive step, it has been imagined to associate with the opening manually locking means lockable while being able to be maneuvers automatically in the initial phase of opening control under the influence of the engine .

The advantages that flow from the present invention are that the closure system, although motorized, behaves as a closing system and manual opening. Indeed, as long as the engine is stopped, in this case, both it is not supplied with electrical energy, it is completely disconnected from the opening which, after unlocking adapted locking means, can be handled with ease. Thus, in the event of malfunction of the engine, for whatever reason, the user can easily open the door, without having to access, first in the house through another access door. To note that for this, it is enough for him to unlock the door, as it is of use for the opening with manual control, then to push this opening according to the case horizontally or vertically, in order to clear the opening which it closes.

Another advantage results from the fact that whatever the manual or motorized opening mode of the opening, it is kept locked in the closed position by means of locking means which, again, are susceptible of be controlled manually or motorized.

Thus, the invention relates to a motorized closing system with pivoting or sliding opening horizontally or vertically according to claim 1.

As shown in the figures of the accompanying drawings, the present invention relates to the field of motorized closing systems with pivoting or sliding horizontally or vertically.

It is more particularly shown in the accompanying drawings, the application of the invention to a horizontally sliding sliding door type garage door.

The motorized closing system 1 according to the invention comprises a motor unit 2, of the electric motor type, which, through a motor drive shaft, not directly visible in the drawings, acts by means of a transmission adapted 4 on the opening 5 which, as already indicated above, can be pivoting type, sliding or otherwise.

In the illustrated embodiments, this opening 5 is of horizontally sliding type as is encountered in the case of garage doors or the like. Such an opening is often made of panels 6 hinged together, to reject it, in the open position, along a wall inside the garage, extending perpendicularly to the opening that closes the opening.

The motorized closure system 1 further comprises locking means 7 more particularly designed to maintain closed the opening 5.

According to a particularity of the invention, the driving member 2 is mounted to move in free rotation around its drive shaft, as long as it is not supplied with electrical energy for the opening and closing control of the drive shaft. opening 5. The motorized closure system 1 also comprises, in the form of clutch means, means 8 for controlling rotation locking said motor member 2, precisely when the latter is supplied with electrical energy to ensure, according to the case the opening and closing of the opening 5.

In a further particularity to the invention, these blocking control means 8 furthermore constitute unlocking control means, locking means 7, in particular in the initial opening phase.

In other words, insofar as the motor member 2 is itself free to rotate and its drive shaft is in cooperation with the opening 5 via the transmission 4, when the drive member 2 is powered by electric power, it comes to turn around its tree drive whose rotation is prevented under the influence of the weight of the opening 5.

It is only once this motor member 2 immobilized with respect to a fixed point, that intervenes the rotation of the drive shaft.

Reference will now be made more particularly to the embodiment corresponding to the Figures 1 to 3 where it is visible an opening 5 in the form of a garage door. This opening 5 is slidably mounted horizontally by means of adapted guiding means 9, 10 formed in the upper and lower part of the opening that it closes.

Furthermore, this opening 5 comprises, in the upper part 11 and lower 12, racks 13, 14 on which are meshing pinions 15, 16 mounted at the ends of a shaft 17, here designed tubular and receiving, internally, the driving member 2.

It acts, through its drive shaft, possibly via a gear 18 adapted on this shaft 17. The latter is maintained in rotation by bearings (not shown) located at the height of the amount rear, opposite the amount before 19, delimiting the opening in the construction and on which is closed the opening 5.

As for the motor member 2, it is of the tubular type introduced into this tubular shaft 17.

Under these conditions, it is clear that the shaft 17 is rotating around the motor member 2, just as it can freely rotate in this tubular shaft 17, as the motor member 2 is not him - even rendering solidarity of a fixed point. In the usual way, this drive member 2 comprises a motor head 20 which is fixed at a console 21 forming by example plays bearing bracket. Precisely, this motor head 20 is free here in rotation.

Exactly, it is here that intervene, according to the invention, on the control means of rotation locking 8 of the motor member 2. These means, in the form of clutch means, may borrow different embodiments. Thus, in the embodiment corresponding to Figures 1 to 3 they are of the electromagnetic type comprising, for example, an electromagnetic suction pad 22 designed adapted to cooperate with a magnetic plate 23, the suction cup 22 attracting the plate 23 in case of supply of electrical energy.

In the illustrated embodiment, the plate 23 is mounted to rotate with the head 20 of the drive member 2, while the suction cup 22 is mounted at a fixed support bracket 21. It is understood that although an inverted arrangement can be envisaged, consisting of equipping the motor head 20 with the suction cup 22, the fixed support 21 then receiving the plate 23.

To return to the illustrated embodiment, the plate 23 is also mounted to move on the motor head 20 so as to be applied against the electromagnetic pad 22 in case of supply of electrical energy, corresponding to the engaged position, or, on the contrary, detach when this power is cut to cause the disengagement. In this connection, elastic return means may be provided to ensure this disengagement when the suction pad is no longer under tension.

Said magnetic plate 23 further comprises means for locking in rotation 24, for example a toothing, designed capable of cooperating, when it is attracted by the electromagnetic pad 22, with complementary locking means 25 associated with the latter.

Thus, it is understood that by feeding this suction cup, it results in the attraction of the magnetic plate 23 and the cooperation of the locking means 24 with those complementary 25 leading simultaneously to block in rotation the motor head 20 The motor unit 2 thus having a fixed point ensuring its immobilization in rotation, its drive shaft can, through the transmission 4, drive the opening 5.

In particular, said rotational locking control means 8 still constitute unlocking control means, locking means 7.

In this regard, the electromagnetic clutch 22 of the electromagnetic clutch corresponding to said blocking control means 8 constitutes, in a way, the fixed plate of this clutch on which the moving plate defined by the magnetic plate 23 engages. this fixed plate is itself free to rotate relative to the console 21 about the axis of rotation of the motor member 2 which is none other than the axis of its drive shaft (not visible).

This rotation of the electromagnetic pad 2 is however limited angularly according to a determined range 26. Thus, when feeding the motor member 2, it starts to rotate around its drive shaft thereby driving the motor head 20. Simultaneously, the blocking control means are activated. rotating 8 consisting in the attraction, by the electromagnetic pad 22, of the magnetic plate 23. Follows the rotation of said electromagnetic pad 22 on the angular range 26.

In particular, the means 27 conferring this angular mobility relative to the electromagnetic pad 22 are constituted, according to an exemplary embodiment, by a tab 28 comprising a semicircular light 29 concentric to the axis. of rotation of this electromagnetic lock 22, therefore of the driving member 2. In this light 29 is engaged a retaining pin 30 integral with the console 21. In other words, the light 29 determines the range 26 of free rotation of the electromagnetic sucker 22. Of course, one could imagine equipping the lug 28 of the retaining pin 30, the light 29 then being formed at the console 21.

Advantageously, said tab 28 driven by the electromagnetic pad 22 constitutes a drive tab for the unlocking control of the locking means 7.

More exactly, this drive lug 28 is designed to act, in particular through a rod 31 on these locking means 7.

These can take various embodiments, it being understood that according to a feature of the invention, said locking means 7 are still designed able to be controlled, also from outside at least the opening 5.

An embodiment of such locking means 7 will be explained further in the description.

Reference will now be made to the embodiment corresponding to the figure 4 where it is shown, in the form of another embodiment, the rotational locking control means 8 of the motor member 2.

In reality, these means 8 retain their configuration in the form of a clutch, in particular an electromagnetic clutch, and comprise an electromagnet 32 designed capable of bringing a locking lug 33 in cooperation with a toothed wheel 34 integral in rotation with the motor head 20. The locking pin 33 has the function, once engaged on the toothed wheel 34, immobilize in rotation of the latter and, consequently, create a fixed point for the drive member 2 which can then produce the opening and closing of the opening 5 under the influence of its drive shaft. Already, it will be observed that instead of a locking lug other locking means may be provided for, in cooperation with complementary locking means associated with the motor head 20, to ensure the blocking in rotation of the latter. The present invention can not be limited to the single embodiment described.

In this embodiment, visible in the figure 4 , the locking pin 33 is mounted integral with a lever 35, for example rotatably mounted on the bracket 21. The electromagnet 32 is designed capable of cooperating with said lever 35 to ensure its rotation from an inactive position of disengagement in a active clutch position, in the latter the locking pin 33 being in cooperation with said toothed wheel 34.

Advantageously, the lever 35 is still a control lever locking means 7 including through a rod 31 adapted.

To return to these locking means 7, they comprise, according to a particular design of the invention, fastening means 36 designed to be reported on the amount before 19 of the frame on which closes the opening 5 and complementary fastening means 37 attached to this opening 5 and with which are designed able to cooperate said fastening means 36.

According to an advantageous embodiment of the invention, these attachment means 36 corresponding to these locking means 7 are able to be controlled, in particular for unlocking, by said locking control means 8 to which it has been made reference above, while the additional hooking means 37 are intended to be manually controlled at least from the outer side of the opening 5.

In an exemplary embodiment, said hooking means 36 are in the form of at least one hook 38 pivotally mounted on the front upright 19 of the frame, in a manner adapted to cooperate with the complementary fastening means 37 in the form of at least one bolt 39 integral with the opening 5. In particular, said hook 38 is subjected to elastic return means 40 in the locking position, while its end 41 is configured in a manner adapted to be pushed back into the unlocked position under the impetus of the bolt 39 when the opening 5 is closed on said amount before 19 of the frame. In sum, the bolt 39 acting on the hook 38, acts against these resilient biasing means 40 so that after passage under the hook 38 it can lock at the rear of said bolt 39.

Moreover, it is advantageously secured to a control rod 42 depending on a locking device 43 of the operating cremone type, in particular by means of a key, from outside the opening 5. The control rod 42 is designed capable of moving the bolt 39 so as to erase it from the grip of the hook 38.

As it is represented more particularly in the figure 1 , the attachment means 36 corresponding to the locking means 7 comprise several hooks 38 mounted integral with a rod 44 pivotally attached about its axis on the front post 19 of the frame. The rotation control of this rod 44 occurs under the impetus of the locking control means 8 more particularly of the rod 31 controlled, as the case may be, by the drive lug 28 of the electromagnetic lock 22 or by the lever 35 on which acts the electromagnet 32.

Along this rod 44 may further be provided, a manual unlocking handle 45 for unlocking from the inside.

However, it can be imagined that this release from the inside intervenes in a manner similar to the unlocking from the outside by action on the espagnolette defining the locking device 43 secured to the opening 5.
