Description

The present invention is in the field of shutters.

The invention more particularly relates to a shutter which comprises a base for receiving the driving motor head of a winding tube.

In general, a roller shutter comprises an apron consisting of a juxtaposition of blades hinged together and intended to be wound around a winding tube. This tube is positioned in a box implanted above an opening corresponding to a door, window or the like within a building.

The winding of the apron on the tube takes place under the action of drive means generally in the form of a motor provided with a head fixed on or in a support cheek, said cheek being integral with a amount of the door or window.

In known manner, the motor head encloses electronic components dedicated to the management and control of the engine. The sensitivity of these components, compared to the strength of the engine, more often causes electronic failures than mechanical. Indeed, the box, sometimes located between the inside and the outside of the house, is often subject to strong temperature differences causing premature aging of the electronic components and ultimately, their dysfunction. In such circumstances, it is necessary to disassemble the entire shutter to change said components often difficult to access or to replace the entire head of the engine.

Another drawback comes from the power supply of the motor through a definitive wiring which, in case of replacement of the motor requires intervention on the electrical network. Indeed, the power cable from the engine to be connected to the home electrical network. If the motor is to be replaced, it is necessary to pull the cable from its connection and replace it with a new one, a tedious operation sometimes requiring soldering the power cables, not to mention the inherent security problems.

Several solutions have been envisaged to allow intervention in case of failure of the electrical and electronic components of said component, without completely replacing the latter.

The document US 2004/0129849 discloses a removable medium receiving the electronic components for engine management. In the form of a plate fixed by screwing on the support cheek along the winding shaft, this support comprises plugs for easily wiring the power supply of the motor.

However, it is still necessary to disassemble the motor, unscrew the said plate during an intervention. In addition, the arrangement of said plate is impractical access.

Two other documents EP 1 106 774 and EP 1 106 775 provide a removable card, fixed by clipping on the support cheek behind the head of the winding shaft. Even if this fixing makes it possible to replace only the support card of the electronic components, this operation still requires disassembly of the winding shaft.

The invention aims to overcome the drawbacks of the state of the art by providing a roller shutter, comprising a base for receiving a motor head, said base being secured to or in a support cheek and comprising electronic components for the management and control of said engine, said base comprising means adapted to removably receive said control and management means, characterized in that said removable receiving means are in the form of a removable drawer relative to said support cheek transversely to the axis of said roller shutter.

According to other features, said removable means comprise latching means of a support card of said electronic components.

Preferably, said removable means comprise contactors to said card, said contactors being connected on the one hand to said motor and on the other hand to a power supply.

According to one embodiment, said power supply comprises means of removable electrical connections, such as a socket.

Preferably, said support cheek is shaped so as to make said removable means accessible through a housing.
