An installation for covering and uncovering a surface includes a series of slats of adjustable inclination supported by pivot pins via a set having a first carriage and a second carriage. A movement system has, for each head slat, movement motors on board the first and second carriages. For the even-numbered slats, firstly a retractable coupling (A) is fastened between the first carriage of said slat and the first carriage belonging to the head slat or to the neighboring slat of lower number, and secondly a drive system (S) is provided for driving the second carriage of said slat in translation. For each odd-numbered slat that is present, a retractable coupling (A) is fastened between the second carriage of said slat and the second carriage belonging to the neighboring slat of lower number, and a drive system (S) is provided for driving the first carriage of said slat in translation.

In one aspect, a shutter assembly includes a shutter frame and a plurality of louvers supported by the frame. The shutter assembly also includes a louver drive assembly and a motor positioned within the frame. The motor is configured to rotationally drive a drive shaft extending within the frame. Additionally, the shutter assembly includes a clutch assembly rotationally coupled between the drive shaft and the louver drive assembly. The clutch assembly is configured to disengage or decouple the drive shaft from the louver drive assembly when a torque transmitted through the clutch assembly exceeds a given torque threshold.

A window shade system includes a first bracket coupled to a first pivot and rotatable at least within a first range of angles, a second bracket coupled to a second pivot and rotatable at least within a second range of angles, and first and second gears that each include a circular base rotatable about a central axis. Gear teeth are arranged in a same row and extend outward from the outer region and are evenly spaced from each other along the outer region of the gears. The first and second pivots are arranged relative to each other and relative to the central axes of the first and second gears, respectively, such that for any angle within the first range of angles, the gear tooth of the first gear meshes with the gear tooth of the second gear at a corresponding angle within the second range of angles.

Modular structures for creating functional spaces are disclosed herein. The modular structures can include partitions, such as walls, storefronts, and/or doors that can be easily assembled in a desired space and selectively paired together to create a desired floorplan suitable for the environment. These modular structures can be used together to create a suitable layout for a co-working space, an office environment, a school, a hospital, a laboratory, a factory, and various other indoor spaces.

A gear includes a circular base having a front surface that includes an inner region and an outer region that surrounds the inner region. The circular base is rotatable about a central axis. Plural gear teeth are arranged in a same row and extend outward from the outer region of the front surface and are evenly spaced from each other along plural locations on the outer region. Each gear tooth has a cross-sectional width that decreases with decreasing distance from the central axis, and has an outer shape configured to permit any one of the gear teeth in the row to contact and directly mesh with any gear tooth in a corresponding row of gear teeth of a substantially identical gear for any gear angle within a predefined range of gear angles between the central axis of the gear and the central axis of the substantially identical gear.
