Description

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

The invention relates to the field of construction and, more particularly, to the manufacture of devices designed to ensure the closing of an opening in a construction, in particular the manufacture of devices comprising at least one hinged shutter.

Closing devices are already known which comprise at least one hinged shutter as well as motorized means for rotating such a hinged shutter.

So the document DE9418875U1 discloses such a closing device in which the motorized drive means comprise, on the one hand, a motor fixed to the masonry and, on the other hand, means for transmitting a rotational movement generated by the motor to a hinged shutter. Such a transmission means comprises, on the one hand, a shaft engaged with said hinged shutter and, on the other hand, a gear train interposed between said motor and said shaft. Such a closing device has many drawbacks. In particular, the presence of the motor fixed to the masonry requires, on the one hand, designing a hinged shutter whose dimensions are significantly smaller than those of the opening in the masonry, on the other hand, providing a specific system for articulating the hinged shutter and, on the other hand, mounting this hinged shutter in rotation in an offset manner relative to the masonry. Such a hinged shutter is then mounted in rotation on the free end of an arm extending from the frame of a door, window or the like. Such an assembly requires providing a frame that is wide enough to allow the attachment of such an arm and rigid enough to support the weight of the opening as well as that of the hinged shutter(s). The choice of such a frame is made to the detriment of the opening and, more particularly, to the detriment of the glazed surface of this opening, which is singularly reduced.

We know, again and through the document FROM 10 2004 061 913 , a device for closing an opening in a masonry. This closing device comprises a hinged shutter as well as motorized means for driving this hinged shutter in rotation about an axis. These motorized drive means comprise a motor that the hinged shutter comprises. These motorized drive means also comprise meshing means, that the hinged shutter comprises, which are driven by said motor, and which are constituted by a gear train. These motorized drive means also comprise complementary meshing means, which are intended to be made fixedly integral with a hinge, and which comprise a fixed hollow toothed wheel as well as a toothed wheel, movable inside the hollow toothed wheel, and cooperating with this hollow toothed wheel in an eccentric manner. 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 movable toothed wheel. These motorized drive means have complex kinematics, requiring a complex design, and using many specific parts. This results in a high cost and risk of failure.

We also know, and by the document CN 104 033 053 , a closing device which has the characteristics of the preamble of claim 1.

The present invention aims to remedy the drawbacks of the closing devices of the state of the art.

For this purpose, the invention relates to a device for closing an opening in the masonry of a building. This device comprises a hinged shutter and motorized means for driving the hinged shutter in rotation about an axis. These motorized drive means comprise, on the one hand, a motor that the hinged shutter comprises, on the other hand, meshing means, that the hinged shutter comprises, and which are driven by said motor and, on the other hand, complementary meshing means, which cooperate with the means of engagement of the hinged shutter, and which are intended to be made fixedly integral with the masonry.

This closing device is characterized by the fact that the meshing means are constituted by a toothed wheel while the complementary meshing means are constituted by a toothed or notched circular sector, which cooperates directly with the toothed wheel constituting the meshing means, and which comprises an external edge which has at least one portion of a disk intended to be made fixedly integral with the masonry.

According to the invention, the hinged shutter comprises a housing while the motor is at least partly housed inside this housing.

More specifically, the hinged shutter 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 this 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 mobile 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 rotor of the motor.

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

An additional feature of the invention concerns the fact that the closing device comprises securing means for making the complementary engagement means fixedly secured to the masonry.

Yet another feature of the invention is that the closing device comprises means for mounting the shutter. swinging on the masonry of the construction, this in rotation around said axis of rotation of the swing shutter.

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

Another feature concerns the fact that the hinged shutter 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 inside a housing which the hinged shutter comprises and, on the other hand, a photovoltaic panel, connected to this battery, and, as the case may be, attached to the hinged shutter or integrated into this hinged shutter.

Thus, the closing device according to the invention comprises a motor that the hinged shutter comprises. In fact, such a motor is housed inside a housing that such a hinged shutter comprises, more particularly that comprises a tubular profile forming part of the composition of a frame that this hinged shutter comprises. Said motor is, therefore, integrated into the hinged shutter and is no longer, as in the prior art, fixed to the masonry. This advantageously makes it possible to size the hinged shutter to the size of the opening in the masonry.

This also allows the hinged shutter to be mounted directly in rotation on the masonry, which advantageously has the effect of making such an assembly more reliable and reinforcing. Additionally, to ensure such an assembly, it may advantageously be used to use traditional type assembly means (of the hinge type or similar), or even to take advantage of assembly means (in particular a hinge included in such assembly means) already fitted to a construction.

Furthermore, such an assembly makes it possible to avoid, as in the prior art, a mounting of the hinged shutter on the frame of a door, window or the like. This then advantageously makes it possible to choose a door, window or the like of traditional type and/or whose frame has reduced dimensions and, thus, an opening whose glazed surface is increased compared to those of the openings of doors, windows of the state of the art.

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

In addition, the parts of these motorized drive means are of classic, proven, simple and robust design, which helps to increase the reliability of the closing device.

The closing device also includes means for mounting the hinged shutter on the masonry. This makes it possible to reinforce and make more reliable the mounting of said hinged shutter on the construction but also, and as mentioned above, to take advantage of the mounting means already equipping such a construction.

Other aims and advantages of the present invention will become apparent during the description which follows relating to embodiments which are given only as indicative and non-limiting examples.

The present invention relates to the field of construction and, more particularly, to the manufacture of devices designed to ensure the closing of an opening O contained in the masonry M of a construction.

In fact, such a closing device 1 comprises at least one hinged shutter 2 as well as mounting means 3 for mounting such a hinged shutter 2 on the masonry M of the construction, this in rotation around an axis 4, usually vertical.

The closing device 1 also comprises motorized drive means 5 for driving the swing shutter 2, this in rotation around said axis 4. Such motorized drive means 5 comprise at least one motor 6. Such a motor 6 comprises a stator as well as a rotor movable relative to said stator, this in rotation around an axis 9. In fact, this axis 9 is, more particularly, parallel to the axis 4 of rotation of the swing shutter 2.

In fact, it is this hinged shutter 2 which comprises such a motor 6. The stator of such a motor 6 is then made fixedly integral with said hinged shutter 2.

In this regard, it will be observed that this hinged shutter 2 then comprises a housing 20 and that this motor 6 is at least partly housed inside this housing 20.

In fact, according to a preferred embodiment of the invention, the hinged shutter 2 comprises a frame 21 as well as a panel 22 extending inside this frame 21.

Such a frame 21 is constituted by an assembly of profiles 23, at least one of which is tubular. Due to this tubular structure of such a profile 23, the latter 23 has internally a housing 20, corresponding to the housing 20 mentioned above, and inside which the motor 6 is at least partly housed.

As visible in the attached figures, the tubular profile 23, having such a housing 20, is constituted by a profile 23 extending vertically.

Another feature is that the hinged shutter 2 is at least partly made of aluminum. In particular, at least one profile 23 that the frame 21 of such a hinged shutter 2 comprises (in particular the tubular profile 23 receiving said motor 6) is then made of aluminum.

Another characteristic of the invention consists in that the motorized drive means 5 also comprise, on the one hand, engagement means 7, which the hinged shutter 2 comprises, and which are driven by said motor 6 and, on the other hand, complementary engagement means 8, which cooperate with the engagement means 7 of the hinged shutter 2, and which are intended to be made fixedly integral with the masonry M.

In this regard and according to a first embodiment not shown, the meshing means 7 may comprise notches while the complementary meshing means 8 may comprise teeth.

In such a case, the meshing means 7 can then be constituted by a toothed wheel while the complementary meshing means 8 can be constituted by a toothed circular sector.

However, and according to a preferred embodiment, the meshing means 7 comprise teeth 70 while the complementary meshing means 8 comprise teeth or (and preferably as visible figure 1 ) notches 80.

In fact, the meshing means 7 are constituted by a toothed wheel 71 (in particular in the form of a pinion or the like), more particularly comprising teeth 70 as mentioned above. The complementary meshing means 8 are, then, constituted by a toothed circular sector or (and preferably as visible figures 1 And 2 ) by a notched circular sector 81. Such a toothed circular sector, respectively notched 81, then comprises teeth, respectively notches 80, as mentioned above.

Another feature is that, on the one hand, the teeth 70 and/or the toothed wheel 81 of the meshing means 7 and, on the other hand, the teeth, the notches 80, the toothed circular sector or the notched circular sector 81 of the complementary meshing means 8 extend in a plane perpendicular to the axis of rotation 4 of the hinged shutter 2.

As mentioned above, the meshing means 7 are driven by the motor 6.

In this regard, it will be observed that this motor 6 then comprises drive means for driving the toothed wheel 71 of these meshing means 7, this in rotation around the axis 9 of rotation of the rotor of the motor 6.

These drive means are also designed to drive the toothed wheel 71 of these meshing means 7, in rotation around an axis, parallel to the axis of rotation 4 of the hinged shutter 2, and more particularly constituted by the axis 9 of rotation of the rotor of the motor 6.

In fact, such drive means can be constituted by a shaft secured, on the one hand, to the rotor of the motor 6 and, on the other hand, to the toothed wheel 71.

As mentioned above, the complementary meshing means 8 comprise a toothed circular sector or a notched circular sector 81.

In fact and according to a preferred embodiment of the invention, the complementary drive means 8 are constituted by such a toothed circular sector or by such a notched circular sector 81.

In this regard, it will be observed that such a toothed circular sector, respectively notched 81, has an edge 82 comprising said teeth, respectively said notches 80.

Another characteristic of the invention consists in that the closing device 1 comprises at least one portion of disc 10, having an external edge 100, which 100 then comprises the toothed or notched circular sector 81.

Furthermore, such a toothed circular sector, respectively notched 81, has a center 83. In fact, it is more particularly through this center 83 that the axis of rotation 4 of the hinged shutter 2 passes.

Another feature is that said at least one portion of disk 10 also has a center 101, through which passes the axis of rotation 4 of the hinged shutter 2, and coinciding with the center of the toothed or notched circular sector 81.

These complementary meshing means 8 (more particularly the toothed or notched circular sector 81) cooperate directly with the toothed wheel 71 of the meshing means 7.

A characteristic of the invention consists in that the closing device 1 also comprises securing means to make the complementary meshing means 8 (more particularly the toothed or notched circular sector 81) fixedly secured to the masonry M.

In fact, these securing means are, more particularly, designed to make said at least one portion of disk 10 (having the external edge 100 comprising the toothed or notched sector 81) fixedly secured to the masonry M.

According to a particular embodiment, these securing means consist of at least one sealing member in the masonry M.

In fact, these securing means are, more particularly, constituted by said at least one sealing member which comprises or which completes said at least one portion of disk 10.

As mentioned above, the closing device 1 comprises means 3 for mounting the hinged shutter 2 on the masonry M of the construction, this in rotation about said axis of rotation 4 of the hinged shutter 2. Such mounting means 3 comprise, on the one hand, a hinge 30 intended to be made fixedly integral with the masonry M, in particular by sealing, screwing or other and, on the other hand, a hinge 31, made integral with the hinged shutter 2 (in particular by screwing), and mounted on the hinge 30, this in rotation about the axis of rotation 4 of the hinged shutter 2.

Also and according to a particular embodiment, the securing means mentioned above comprise means for fixing the complementary meshing means 8 on said hinge 30, this more particularly by means of the fixing of said at least one portion of disk 10 on this hinge 30. Also through, on the one hand, the fixing of these complementary engagement means 8 on said hinge 30 and, on the other hand, the fixing of the hinge 30 on the masonry M, these complementary engagement means 8 are made fixedly integral with this masonry M.

In fact, the securing (more particularly the fixing) of these complementary meshing means 8 (more particularly by means of the fixing of said at least one portion of disk 10) is carried out so that the axis of rotation 4 of the hinged shutter 2 passes through the center 83 of the circular sector, depending on the case, toothed or notched 81 and/or through the center 101 of said at least one portion of disk 10.

Another characteristic of the invention consists in that the closing device 1 comprises means for supplying the motor 6 with electrical energy.

In fact, it is, more particularly, the hinged shutter 2 which includes such means of supplying the motor 6 with electrical energy.

Such means of supplying electrical energy comprise, on the one hand, a battery, connected to said motor 6, and housed inside a housing that the hinged shutter 2 comprises and, on the other hand, a photovoltaic panel, connected to this battery, and, as the case may be, attached to the hinged shutter 2 or integrated into this hinged shutter 2.

In fact, like said motor 6, said battery can be housed inside a housing which comprises a tubular profile 23 of the frame 21 of the hinged shutter 2.
