Description

Field of application

[0001] The present invention relates to a cover plate group for a winder seat of a winder box, in which a winder of a shutter suitable for closing a window or glass door compartment is generally placed. Furthermore, the present invention also relates to a cover plate.

[0002] The present patent application relates to the field of shutter winders and, more specifically, to a cover plate for a winder box, designed to improve the aesthetics and functionality of existing winder boxes, especially in cases of non-use or replacement with motorized winders.

[0003] With the advent of automated solutions, the conversion of existing shutter winder installations with the integration of a motor for the automatic movement of the shutter is often required. This conversion often requires invasive interventions such as masonry works for positioning the motor control switch. This not only increases costs and installation times but may also affect the aesthetic and structural integrity of the environment.

[0004] Alternatively, it is possible to fasten a switch at a separate point, but this solution also results in a suboptimal modification of the surrounding space, negatively affecting the harmony of the interior design, or requires the presence of a wireless remote control, which in some cases may be inconvenient in its use.

Solution of the invention

[0005] The need felt is therefore to simplify the installation process of the control switches for shutter motors, minimizing the need for masonry works and keeping the aesthetics of the environment unchanged. A solution that allows the control switch to be easily integrated into the winder system, without the need to significantly alter existing structures or add external elements, represents a marked progress in the sector.

[0006] There is therefore a strong need to provide a cover plate group and a cover plate that are capable of overcoming the drawbacks mentioned with reference to the prior art.

[0007] Also an object of the present invention is to provide a cover plate group that is easy to install, compatible with standard winder boxes and capable of aesthetically adapting to various residential contexts whilst maintaining a discrete or elegant profile.

[0008] Such requirements are satisfied by a cover plate group and by a cover plate in accordance with the attached independent claims. The dependent claims describe preferred or advantageous embodiments of the invention, comprising further advantageous features.

[0037] Further, preferably, the cover plate 3 is devoid of any other opening or hole for fastening the cover plate 3 to the sub-plate 10 and/or to a winder box 2.

[0038] Innovatively, the present invention brilliantly overcomes the drawbacks of the prior art and meets the needs of the industry.

[0039] The proposed solution is easy to install and remove, is compatible with standard winder boxes and is capable of aesthetically adapting to various residential contexts, whilst maintaining a discrete profile.

[0040] In a brilliant manner, the cover plate group allows the box seat to be recovered by installing the switch in said seat by means of the cover plate group, in the case of retrofitting a manual winder with a motorized winder. In effect, the switch is placed into the box seat and the winder box may be used for the electrical connections without requiring excessive masonry works for the installation of the control switch.

[0041] Advantageously, the possibility of snap-removing the plate allows the aesthetics of the plate to be adapted and re-adapted quickly to the residential context, without having to carry out screwing operations.

[0042] Similarly, it is also possible to change the type of switch in a simple manner.

[0043] In addition, the fact that the switch is supported directly by the cover plate ensures further ease of installation and fastening of the electrical connections to the switch, since it is not necessary to remove the sub-plate.

[0044] Furthermore, advantageously, the present invention allows manual winders to be retrofitted without having to cover the winder seat box with masonry works, instead using it exactly for that purpose.

[0045] Furthermore, due to the presence of the sub-plate, where it is necessary to restore the manual winder, this would be immediate by virtue of the possibility of removing only the cover plate, snapped in place onto the sub-plate which is already provided with the opening for the passage of a belt.

[0046] Furthermore, the fact that the cover plate has no further openings, but only the fastening holes of the switch, allows for a simple and linear plate to be obtained, especially since the switch plate also covers the fastening screws of the switch, making the whole assembled group 200 cover plate 3 and switch 4 completely devoid of visible screws.
