Description

The present invention relates to a device for closing an opening that includes the masonry of a building.

The invention relates to the field of the building and, more particularly, that of the manufacture of devices designed to ensure the closure of an opening that includes a construction, including the manufacture of devices comprising at least one flap.

There are already known closure devices which comprise at least one flap flap and motorized means for driving in rotation of such flap shutter.

Thus, the document DE9418875U1 discloses such a closure device in which the motorized drive means comprise, on the one hand, a motor fixed on the masonry and, on the other hand, means for transmitting a rotational movement generated by the motor to a motor. flap shutter. Such transmission means comprises, on the one hand, a shaft engaged with said flap flap and, on the other hand, a gear train interposed between said motor and said shaft. Such a closure device has many disadvantages. In particular, the presence of the engine fixed on the masonry requires, on the one hand, to design a swing shutter whose dimensions are significantly smaller than those of the opening of the masonry, on the other hand, to provide a specific system of articulation of the flap flap and, secondly, to mount the flap flying in rotation offset from the masonry. Such a flap is then rotatably mounted on the free end of an arm extending from the frame of a door, window or the like. Such an assembly requires a frame sufficiently large to allow the attachment of such an arm and rigid enough to support the weight of the opening and that of the flaps or shutters. The choice of such a frame is to the detriment of the opening and, more particularly, to the detriment of the glass surface of this opening which is singularly reduced.

We know, again and by the document DE10 2004 061 913 , a device for closing an opening of a masonry. This closing device comprises a swing flap as well as motorized means for driving this shutter flapping in rotation about an axis. These motorized drive means comprise a motor that includes the flap. These motorized drive means further comprise meshing means, which includes the flap, which are driven by said motor, and which are constituted by a gear train. These motorized drive means also include complementary meshing means, which are intended to be fixedly secured to a hinge, and which comprise a fixed hollow gear and a toothed wheel, movable inside. the hollow gear, and cooperating with this hollow gear eccentrically. These complementary meshing means cooperate with the meshing means, this by means of transmission means, which comprise the motorized drive means, and which are engaged, on the one hand, with the gear train and, on the other hand and eccentrically, with the moving gear. These motorized drive means have a complex kinematic, requiring a complex design, and using many specific parts. This results in a high cost and a high risk of failure.

The present invention aims to overcome the disadvantages of closure devices of the state of the art.

To this end, the invention relates to a device for closing an opening that includes the masonry of a building. This device comprises a flap flap as well as motorized means for driving the shutter flapping in rotation about an axis. These motorized drive means comprise, on the one hand, a motor that comprises the flap flap, on the other hand, meshing means, that includes the flap flap, and which are driven by said engine and, other Moreover, complementary meshing means, which cooperate with the meshing means of the flap shutter, and which are intended to be fixed solidarity masonry.

This closure device is characterized in that the meshing means consist of a toothed wheel while the complementary meshing means consist of a toothed circular sector or notched, which cooperates directly with the toothed wheel constituting the means of meshing, and that includes an outer rim that has at least a portion of disk to be fixedly secured to the masonry.

According to another characteristic, the flap comprises a housing while the engine is at least partly housed inside this housing.

More specifically, the swing flap comprises a frame consisting of an assembly of profiles at least one of which is tubular and has a housing while the motor is at least partly housed inside the housing.

Yet another feature is that the meshing means comprise teeth while the complementary meshing means comprise teeth or notches.

According to another characteristic, the motor comprises, on the one hand, a rotor movable in rotation about an axis and, on the other hand, drive means for driving the toothed wheel in rotation about the axis of rotation of the motor rotor.

An additional feature is that the toothed or notched circular sector has a center through which the axis of rotation of the swing flap passes. It is, more particularly, said at least one portion of disc which then has a center through which the axis of rotation of the flap flap.

An additional feature relates to the fact that the closure device comprises securing means to make complementary meshing means solidly fixed to the masonry.

Yet another feature is that the closure device comprises means for mounting the shutter beating on the masonry of the construction, this in rotation about said axis of rotation of the swing shutter.

In fact, these mounting means comprise a hinge while the securing means comprise means for fixing complementary meshing means on said hinge.

Another characteristic relates to the fact that the flap comprises means for supplying the motor with electrical energy and that these means for supplying electrical energy comprise, on the one hand, a battery, connected to said motor, and housed in the housing. inside a housing that includes the swing shutter and, secondly, a photovoltaic panel, connected to the battery, and, as the case, reported on the flap or integrated flap flap.

Thus, the closure device according to the invention comprises a motor that includes the flap. In fact, such a motor is housed inside a housing that includes such a flap flap, more particularly that comprises a tubular section entering the composition of a frame that includes the flap. Said motor is, therefore, integrated into the flap and is no longer, as in the state of the art, fixed on the masonry. This advantageously allows the flap to be sized to the size of the opening of the masonry.

This also makes it possible to mount the flap directly rotating on the masonry having, advantageously, to make reliable and strengthen such a mounting. In addition, to ensure such an assembly, it can advantageously be resorted to traditional type of mounting means (the hinge type or the like), or even take advantage of mounting means (including a hinge that includes such mounting means) equipping already a construction.

In addition, such an arrangement avoids, as in the state of the art, mounting the flap flap on the frame of a door, window or the like. This allows, then advantageously, to choose a door, window or the like of traditional type and / or whose frame has reduced dimensions and, thus, an opening whose glass surface is increased compared to those of the opening doors, windows of the state of the art.

It will also be observed that the closure device comprises motorized drive means which comprise a limited number of parts (motor, meshing means, complementary meshing means) which simplifies the design of the closure device according to the invention. invention, and reduces the cost as well as the risk of failure.

In addition, the parts of these motorized drive means are of conventional design, proven, simple and robust which increases the reliability of the closure device.

The closure device also comprises means for mounting the shutter flap on the masonry. This makes it possible to strengthen and make reliable the mounting of said flap flap on the construction but also, and as mentioned above, to take advantage of the mounting means equipping, already, such a construction.
