DESCRIPTION

Motorized closing system of rotating or sliding blade

The invention relates to a motorized closing system of rotating or sliding leaf horizontally or vertically, according to the preamble of claim 1.

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

The closing systems for building of garage doors or sliding leaf portals involve, for the motorized operation of this type of leaf, rack transmission systems.

In particular, such a rack with which a cogwheel driven in rotation by an electric motor, often through an adapted reducer, is fixed on the leaf.

Usually, by means of such transmission and engine the blade is also kept in the closed position. In fact, it is usual to use an irreversible transmission system or also use an electromagnetic brake motor for this type of application.

If the motor is capable of rotating the cogwheel to drive the rack, a thrust exerted on the blade to obtain its opening is impossible with an irreversible transmission.

In case of use of an electromagnetic brake motor, the latter is usually activated as soon as the power supply is cut off. Thus, when the motor stops being fed, the brake prevents the rotation of the rotor and therefore of the motor drive shaft. This blocking is effected through the gearbox on the gearwheel that acts on the rack mounted on the blade.

To complete the maintenance in locked position of this sheet, it is also frequent to use electromagnetic locking systems in the form of a bolt pushed in an unlocked position when the motor is powered by electric power and, conversely, backtracked in a locked position when the blade is fully enclosed

The problem posed by these known motorized closing systems lies in the difficulty of obtaining the opening of this sheet in the event of engine failure or simply of a sector cut.

In fact, the solution usually consists in carrying out a disengagement maneuver of the motor and eventually proceeding to a manual unlocking of the auxiliary closing systems, of the electromagnetic lock type or the like.

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

Therefore, either there is another access door to enter this house and thus ensure the opening of the sheet from the inside, or it is provided at the level of this sheet, in this case when it comes to garage doors, a door whose opening can be obtained by means of a conventional locking system of the locking hardware type.

However, according to the type of sheet in question, the latter cannot be systematically equipped with such a door, or at least not without restriction.

This is the case of certain portals, but also of garage doors whose leaf consists of several panels articulated with respect to each other to be able to extend, in an open position, as the case may be, along the roof of the garage or a wall adjacent to that which involves the opening that the leaf closes.

In this case, sectional doors are usually talked about in the presence of this type of articulated panel sheet.

However, the addition of such a door results in substantially increasing the weight of the sheet and the complexity of its structure, which results, of course, in a non-negligible cost overrun.

Also known from DE-A-195 01 624 is a roller shutter that includes an intended board capable of winding around a winding tube that houses a tubular motor. This winding tube has, at each of its ends, shaft segments mounted so as to rotate freely in openings adapted in lateral support plates. One of these axis segments, at one end of the winding tube, radially carries a locking lever whose angular displacement by rotation of said axis segment is limited by two fixed stops on the support side plate.

The locking lever acts through a coupling and transmission mechanism on an intended locking bolt capable of cooperating with a sheet of the board when the latter is in the deployed position.

Thus, during the drive control of the winding tube by the tubular motor, in the direction of folding the board, the resistance provided by the weight of the latter leads to exerting on said tubular motor a torque resulting in its rotation in the range limited by the two stops that cooperate with the locking lever.

The angular displacement imparted to the latter leads to the unlocking control of the bolt acting on a sheet of the board.

Although this solution of the state of the art has the advantage of providing an additional locking point of the roller blind panel when deployed, it does not solve the problem of the folding control, therefore opening this roller blind and dysfunction the motor. Although it can be imagined that the bolt can be unlocked from inside the house and manually, it is also necessary to ensure the motor clutch that can freely rotate around its drive shaft only in the travel range of the lever blocking between the two stops.

The present invention aims to be able to solve this difficulty. Thus, in a first inventive activity, it has been imagined that, outside the opening and closing maneuver phases, the drive motor is disconnected from the leaf, so that any manipulation of this leaf from outside the home becomes independent of the motorized drive mechanism.

Within the framework of a second inventive activity, it has been imagined to associate with the blade blocking means that can be manually maneuvered, while they are capable of being maneuvered automatically in the initial phase of the opening control under the motor action.

The advantages that derive from the present invention consist in that the closing system, although this motorized, behaves like a manual closing and opening system. Indeed, while the engine is stopped, in this case, while it is not powered by electric power, it is completely disconnected from the blade which, after unlocking the adapted locking means, can be easily manipulated. Thus, in case of engine dysfunction, regardless of the reason, the user can easily open the sheet, without having to access, first to the house when passing through another access door. It will be noted that for this purpose, it is sufficient to unlock the door, as is usual for the manual control sheets, then push this sheet, as appropriate, horizontally or vertically to release the closing opening.

Another advantage is that, regardless of the manual or motorized opening mode of the sheet, the latter is kept locked in a closed position through locking means which, also here, are capable of being controlled manually or in a motorized manner.

Thus, the invention relates to a motorized closing system of rotating or sliding blade horizontally or vertically, according to claim 1.

Other objectives and advantages of the present invention will appear in the course of the description that follows and refers to embodiments given by way of indication and not restrictive.

The motorized closing system 1 according to the invention involves an electric motor-type organ 2, which through a motor drive shaft, not directly visible in the drawings, acts by means of an adapted transmission 4 on the sheet 5 which, as already indicated above, can be of the rotating, sliding or similar type.

In the illustrated embodiments, this sheet 5 is horizontally sliding, such as that found in the case of garage doors or the like. Such a leaf often consists of panels 6 articulated with each other, which allows it to be pushed, in an open position, along an interior wall of the garage that extends perpendicularly to the opening that this leaf closes.

The motorized closing system 1 also includes locking means 7, more particularly provided capable of keeping the sheet 5 closed.

According to a particular feature of the invention, the motor organ 2 is mounted mobile in free rotation around its drive axis, as long as it is not powered by electric energy for the control of opening and closing of the leaf 5. The closing system motorized 1 also includes, in the form of clutch means, rotating control means 8 of said motor organ 2, precisely when the latter is powered by electric energy to ensure, as the case may be, the opening and closing of the leaf 5.

Also particularly particular to the invention, these blocking control means 8 also constitute unlocking control means, blocking means 7, in particular in the initial opening phase.

In other words, to the extent that the motor organ 2 can, in turn, rotate freely and that its drive shaft is in cooperation with the leaf 5 through the transmission 4, when this motor organ 2 is energized electric, rotates around its drive shaft whose rotation is prevented under the action of the weight of the blade 5.

Only once this motor organ 2 is immobilized with respect to a fixed point does the rotation of the drive shaft intervene.

We now refer more particularly to the embodiment corresponding to Figures 1 to 3, where a sheet 5 in the form of a garage door is visible. This sheet 5 is mounted horizontally sliding thanks to adapted guiding means 9, 10 provided in the upper part and the lower part of the closing opening.

On the other hand, this sheet 5 has, at the top 11 and the bottom 12, zippers 13, 14 with which gear wheels 15, 16 mounted on the ends of an axle 17, which are provided in a tubular manner and receive inside the motor organ 2.

The latter acts through its drive shaft, possibly through an adapted reducer 18, on this axis 17. The latter is maintained in rotation by means of bearings (not shown) that are located at the height of the rear post, opposite the front post 19, which delimits the opening in the building and against which leaf 5 closes.

As for the motor organ 2, this is of the tubular type inserted in this tubular shaft 17.

Under these conditions, it is understood that the axis 17 is rotatable around the motor organ 2, just as the latter can freely rotate in this tubular axis 17, while the motor organ 2 is not, in turn, attached to a fixed point . In the usual way, this motor organ 2 comprises a motor head 20 which is fixed at the level of a console 21 which forms for example a support side plate. Precisely, this motor head 20 can rotate freely here.

Precisely, according to the invention, the rotational locking control means 8 of the motor organ 2 intervene, according to the invention. These means, in the form of clutch means, can adopt various embodiments. Thus, in the embodiment corresponding to Figures 1 to 3, these are of the electromagnetic type which, for example, include an electromagnetic suction cup 22 provided capable of cooperating with a magnetic plate 23, the suction cup 22 attracting the plate 23 in case of power. With electric energy.

In the illustrated embodiment, the plate 23 is mounted rotatably attached to the head 20 of the motor organ 2, while the suction cup 22 is, in turn, mounted at the level of a fixed support console 21. It is understood that it can be Consider an inverse arrangement consisting of equipping the motor head 20 of the suction cup 22, receiving the fixed support 21 then the plate 23.

Returning to the illustrated embodiment, the plate 23 is also mounted on the motor head 20 so, as the case may be, to be applied against the electromagnetic suction cup 22 in case of power supply

electric, which corresponds to the clutch position, or, conversely, to separate from it when this power is cut to cause disengagement. To this end, elastic recoil means can be provided to ensure this disengagement when the suction cup is no longer activated.

Said magnetic plate 23 also includes rotating locking means 24, for example an intended denture capable of cooperating, when it is trapped by the electromagnetic suction cup 22, with complementary locking means 25 associated with the latter.

Thus, it is understood that feeding this suction cup with current results in the attraction of the magnetic plate 23 and the cooperation of the blocking means 24 with those complementary 25 which leads at the same time to the rotation block of the motor head 20. Since the The motor organ 2 thus has a fixed point that ensures its immobilization in rotation, its motor drive axis can, through the transmission 4, operate the leaf 5.

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

For this purpose, the electromagnetic suction cup 22 of the electromagnetic clutch corresponding to said blocking control means 8 constitutes in some way the fixed plate of this clutch with which the mobile plate defined by the magnetic plate 23 meshes. Actually, this plate fixed can, in turn, rotate freely with respect to the console 21 around the axis of rotation of the motor organ 2 which is none other than the axis of its drive shaft (not visible).

This rotation of the electromagnetic suction cup 2 is however angularly limited to a certain range 26. Thus, during the feeding of the motor organ 2, the latter begins to rotate around its driving axis and thus drives the motor head 20. Simultaneously the rotating locking control means 8 are activated, which consists in the attraction by the electromagnetic suction cup 22 of the magnetic plate 23. The rotation of said electromagnetic suction cup 22 follows the angular range 26.

In particular, the means 27 that impart this angular mobility relative to the electromagnetic suction cup 22 are constituted, according to an example of embodiment, by a tongue 28 which comprises a concentric semicircular hole 29 to the axis of rotation of this electromagnetic suction cup 22, therefore to the motor organ 2. In this hole 29 a retaining pin 30 is attached to the console 21. In other words, the hole 29 determines the range 26 of free rotation of the electromagnetic suction cup 22. Obviously, it can be imagined to equip the tongue 28 of the retaining pin 30, the hole 29 then being provided at the level of the console 21.

Advantageously, said tongue 28 actuated by the electromagnetic suction cup 22 constitutes an actuation tongue for the unlocking control of the blocking means 7.

More precisely, this actuation tab 28 is provided capable of acting, in particular through a rod 31, on these locking means 7.

These can take various forms of embodiment, it being understood that, according to a particular feature of the invention, said blocking means 7 are also provided capable of being controlled also from the outside at least of sheet 5.

An embodiment of such blocking means 7 will be explained later in the description.

We now refer to the embodiment corresponding to Figure 4, where we see represented, in another form of embodiment, the rotating lock control means 8 of the motor organ 2.

In fact, these means 8 retain their configuration in the form of a clutch, in particular electromagnetic, and include an electro-magnet 32 capable of carrying a locking pin 33 in cooperation with a cogwheel 34 rotated together with the motor head 20. The locking pin 33 has the function, once inserted on the sprocket 34, to ensure the immobilization in rotation of the latter and, consequently, to create a fixed point for the motor organ 2 which can then produce the opening and the closing of the blade 5 under the impulse of its drive shaft. It is already noted that instead of a locking pin other locking means may be provided to, in cooperation with complementary locking means associated with the motor head 20, ensure the latter's rotation lock. The present invention cannot be limited to the only embodiment described.

In this embodiment, visible in FIG. 4, the locking pin 33 is mounted attached to a lever 35, for example mounted in rotation on the console 21. The electroiman 32 is provided capable of cooperating with said lever 35 to ensure its rotation of an inactive clutch position in an active clutch position, the locking pin 33 in the latter being in cooperation with said cogwheel 34.

Advantageously, the lever 35 also constitutes a control lever of the locking means 7, in particular through an adapted rod 31.

In order to return to these locking means 7, these, according to a particular conception of the invention, provide intended coupling means 36 capable of being fixed in application against the front upright 19 of the frame against which the sheet 5 is closed and coupling means complementary 37 fixed in application against this sheet 5 and with which said coupling means 36 are provided capable of cooperating.

According to an advantageous embodiment of the invention, these latching means 36 corresponding to these locking means 7 are capable of being controlled, in particular for unlocking, by said blocking control means 8 to which we have referred more above, while the complementary coupling means 37 are provided to be controlled manually at least from the outer side of the sheet 5.

In an exemplary embodiment, said hooking means 36 are in the form of at least one hook 38 rotatably mounted on the front upright 19 of the frame, so as to be able to cooperate with the complementary hooking means 37 that take the form of at least a latch 39 attached to the blade 5. In particular, said hook 38 is subjected to elastic recoil means 40 in the locked position, while its end 41 is configured capable of being pushed in the unlocked position under the pulse of the latch 39 when the sheet 5 closes against the front post 19 of the frame. In sum, the latch 39, when intervening on the hook 38, acts against these elastic recoil means 40 so that, after passing under the hook 38, it can be locked behind said latch 39.

In addition, this is advantageously connected to a control rod 42 which depends on a locking device 43 of the type that could be operated, in particular by means of a key, from the outside of the leaf 5. The control rod 42 is provided capable of move the latch 39 so as to retract the latter from the action of the hook 38.

As shown more particularly in FIG. 1, the hooking means 36 corresponding to the locking means 7 comprise several hooks 38 mounted together with a rod 44 rotatably fixed around its axis in the front post 19 of the frame. The rotating control of this rod 44 intervenes under the impulse of the blocking control means 8, in particular of the rod 31 controlled, as the case may be, by the actuation tab 28 of the electromagnetic suction cup 22 or by the lever 35 on which acts the electromagnetic suction cup 32.

Along this rod 44 a manual unlocking handle 45 can also be provided which allows the unlocking from the inside.

However, it can be imagined that this unlocking from the inside intervenes similarly to the unlocking from the outside by means of an action on the fault that defines the blocking device 43 attached to the sheet 5.
