Modular multifunction shading device, particularly for a pergola
View Patent ↗A multifunction shading device for creating a pergola. The device includes a structure that provides support for the device. The device also includes modules, each module equipped with a blind and a mechanism configured to control a length of the blind distributed along one axis of the structure.
1. A multifunction shading device, comprising:
a horizontal support structure,
a plurality of modules, each module secured to the horizontal structure and equipped with
a blind and
a control apparatus configured to control a length of the blind, the control apparatus comprising
a roller fixed to an end of the blind and
a mechanism configured to drive the roller in rotation, in a first direction of rotation and in a second direction of rotation, thus causing a screen formed by said blinds to be alternately wound up or down,
the modules arranged along a horizontal axis of the horizontal structure,
wherein each blind comprises a base, in a bottom part, connected to a maneuvering device comprising at least one bar connecting the bases, perpendicularly to a major length of the bases, the at least one bar being supported and connected at ends thereof to a traction link, and
wherein the multifunction shading device further comprises a motorized drum to raise and move the at least one bar in horizontal translation.
2. The multifunction shading device according to claim 1 , wherein each roller comprises a pinion integral with each roller respectively and cooperating with a single chain common to the pinions of the rollers, the single chain configured to be rotated by a motor provided with a driving pinion for the single chain.
3. The multifunction shading device according to claim 1 , wherein each roller comprises a toothed pulley integral with each roller respectively and cooperating with a single toothed belt common to the pulleys, the single toothed belt configured to be rotated by a motor provided with a driving pulley for the single toothed belt.
4. The multifunction shading device according to claim 1 , wherein the blinds are made from a material selected from the group consisting of:
coated impermeable waterproof fabric,
permeable sunscreen woven canvas,
and an alternation thereof.
5. The multifunction shading device according to claim 1 , wherein adjacent blinds are configured to wind in opposite directions.
6. The multifunction shading device according to claim 1 , wherein a first blind is configured to wind at a different speed compared to a second blind, and wherein a length of one of the blinds is different from a length of another of the blinds.
