Embodiment Construction

[0036] The present invention proposes optimized positioning of the wind sensor. The purpose is to allow accurate detection of the influence of wind on the blind blades, and this detection has good performance in most possible deployment and turning configurations of the blind. The present invention is mainly aimed at the blinds arranged outside the building and in front of the glass surface, so the blinds are subject to wind. These blinds are usually deployed vertically from top to bottom, and the top of the blind substantially corresponds to the top of the glass surface, and the bottom of the blind substantially corresponds to the bottom of the glass surface.

[0037] The invention is characterized in particular in that the sensor is arranged on one of the first blades of the blind closest to the guide rail.

[0038] When the blind is in the retracted position, the blades are leaned against and stacked on the load-bearing rod, and the steering ropes (also called ladder ropes) are...

Abstract

The invention relates to a Venetian blind (2) to be mounted in front of a building opening, including: a plurality of parallel blades (3) having a substantially horizontal longitudinal axis and supported by cords (4, 4') suspending from a driving mechanism (6), an electromagnetic actuator (5) capable of acting on the driving mechanism for moving an orienting the blades about the longitudinal axis thereof, and a sensor for determining at least one movement characteristic of one or more blades, characterised in that the sensor includes at least one first portion (10) provided on one of the upper blades of the blind.

Description

Technical field [0001] The present invention relates to a sunshade device comprising a blind with steerable blades, the blind being controlled by a motor actuator, the blind being arranged outside the glass surface and subject to wind. The invention also relates to a method of operating such blinds. Background technique [0002] This type of blind, usually called an outer venetian blind, includes: a guide rail; a drive mechanism; a plurality of parallel blades supported by ropes and belts suspended from the drive mechanism; a motor actuator suitable for Act on the drive mechanism to move the blades, for example vertically, and to turn the blades around their longitudinal axis. The belt and rope are additionally fixed on a bearing rod with ballast, which occupies the position of the end blade or the lowest blade of the blind. These blades are guided along lateral chutes or side cables. [0003] The blind is usually combined with a sensor for measuring the influence of wind on the...
