The invention relates to a solar protection installation (1) comprising at least one mobile window blind (2), at least one drive means (3), at least one control unit (4), and at least one wind sensor (5). The wind sensor (5) is used to detect overload caused by the wind on the window blind, by the detection of variations in tension and/or pressure leading to deformations of the window blind. The wind sensor is provided on and/or in the window blind (2).

This invention relates to a retractable and extendable awning and a control system for automatically extending and retracting the awning. In a retractable fabric awning a front of the awning fabric is attached to a movable front bar, movably mounted at the wall of a building by retractable arms. The rear of the fabric is unrolled from a roll of the fabric on the building wall when the arms move the front bar away from the building. The awning features a weather sensor unit on its front bar. The weather sensor unit can detect excessive wind and mechanical shocks and also sunlight and rain. The sensor is in wireless (via radio frequency) communication with an indoor control unit which can automatically retract the front bar during windy, rainy and/or low sunlight conditions and extend the front bar during calm and sunny conditions. The awning also features specific mechanical improvements in the support brackets for the retractable arms and in the retractable arms, themselves. In particular, each support bracket has a screw spindle (for adjusting the angle of extension of the fabric awning from a building) with a resilient inner bushing that cushions mechanical shocks to the awning. Glued-in arm ends allow adhesive to be introduced into the arm ends after assembly of the arms.
摘要:
A drive system for raising and lowering a window covering using a continuous cord loop that includes a motor with an associated encoder, device controller for the motor, a speed sensor, and proportional-integral-derivative (PID) layer. The device controller stores or receives a desired motor speed and generates a speed command signal to the motor. A closed-loop system applies a PID speed control algorithm to an error representing a difference between actual motor speed and desired motor speed. The PID layer uses the error to calculate a new output via PID control terms to automatically correct signals to the motor to achieve desired motor speed. A hembar alignment function automates positional control of a plurality of motor drive systems to synchronize raising or lowering of window covering shades with the shades in positional alignment. A system controller includes a time-counter indexed to a position scale to synchronize hembar alignment positional commands.

A gearbox that is configured to transmit torque from a motor shaft to a load shaft includes a limit mechanism The limit mechanism includes a strain wave gear including a circular spline, a flex spline and a wave generator. The circular spline is fixed to a housing of the gearbox coaxially with the load shaft, the flex spline is formed on a flexible rim of a rotatable cup that is coaxial with the load shaft, and the wave generator is coupled to the load shaft so as to rotate at the same angular velocity. The limit mechanism further includes at least one limiter structure coupled to the rotatable cup and at least one fixed switch, and is configured to stop rotation of the load shaft when the limiter structure engages the fixed switch.

摘要:
An apparatus and method for retracting an awning. A sensor detects an awning acceleration caused by wind impacting the awning, and generates a signal having an amplitude corresponding thereto. When the signal exceeds a certain threshold, the awning is retracted. The signal's amplitude may be converted into a frequency, and the frequency compared to the threshold. The signal typically must exceed the threshold for a set period of time to trigger awning retraction. A second threshold may dictate a maximum instantaneous or peak acceleration; when the signal exceeds this second threshold, regardless of the duration during which the second threshold is exceeded, the awning is retracted.
摘要:
An automatically retractable awning includes a plurality of extendable rafter arms operatively connected at their upper ends to a vertical support surface, a lead bar connected to the lower ends of the rafter arms, a roll bar located adjacent to and operatively connected to the support surface, and an awning sheet or canopy connected at a first end to the roll bar and at a second end to the lead bar. A sensor operatively connected to at least one of the rafter arms detects pivotal movement of the rafter arm relative to the support surface and automatically commands a roll drive motor to roll the canopy about the roll bar and thus retract the awning.
