A window shade that reduces the risk of an individual becoming entangled in cords used to operate the shade includes a headrail adapted for horizontal mounting above a window, a shading material attached to the headrail, and at least one cord for raising and lowering the shading material. The cord is attached to a location adjacent a lower end of the material, and extends upward through cord guides toward the headrail. The cord is encased within a collapsible shroud attached to each cord guide. The shroud is adapted to longitudinally extend as the shading material is lowered toward a deployed position, and then longitudinally collapse as the shading material is raised toward a stowed position. The cord is secured to and is wound about a spring-loaded roller. The roller provides tension on the cord that counterbalances the weight of the shade so that the shading material may be positioned at any desired level.

A window shade comprises a head rail, a shading structure, a bottom part, suspension cords connected with cord winding units, and a control module. The control module includes a drive axle assembled with the cord winding units, a sleeve affixed with the drive axle, an arrester assembled around the drive axle, and a release unit. The arrester has a locking state in which the arrester blocks a rotational displacement of the sleeve and the drive axle to keep the bottom part at a desired position, and an unlocking state in which rotation of the sleeve and the drive axle is allowed to lower the bottom part by gravity action. The release unit includes an actuator that is operatively connected with the arrester and has an elongated shape. The actuator can rotate about its lengthwise axis to turn the arrester from the locking to unlocking state.

A method of operating a motorized window covering is presented wherein in response to a standard movement command power is supplied to a motor in a continuous or generally continuous manner thereby moving the shade material from a start position to an end position in a generally continuous manner. However, in doing so, the motor rotates at a fast rate thereby causing elevated noise levels. In response to an automated movement command, power is supplied to the motor by cycling power to the motor between a powered state and an unpowered state thereby moving the shade material from a start position to an end position in an incremental manner. While moving the shade material in this incremental manner is slower, it is substantially quieter. The preferred mode of operation is selected based on whether the movement command is a standard movement command or an automated movement command. 1.

A blind system may control (e.g., automatically control) an amount of daylight entering a window on a façade of a building to prevent direct sunlight from shining into the building, while maximizing the amount of indirect sunlight in the building. The blind system may tilt one or more slats into a view tilt position in which the slats are horizontal, a slanted tilt position in which the slats may block direct sunlight from shining into the building, and a privacy tilt position in which the slats are vertical. The drive unit may tilt the slats according to a timeclock having the event times determined from a predicted position of the sun, such that the slats are tilted to the slanted tilt position when the predicted position of the sun indicates that direct sunlight is incident on the façade. A facing direction of the façade may be configured using a mobile device.

Unidirectional wire take-up mechanism

Номер: US20200198927A1

Автор: Zheng Bang LEI

Принадлежит: Individual

A unidirectional wire take-up mechanism includes a fixing seat, a reel, a spindle, a unidirectional bearing, a bearing sleeve, a damping bounce member, and a positioning shaft. When the curtain is pulled down, the unidirectional bearing is locked, and the reel links the spindle through the bearing sleeve to rotate counterclockwise. When the spindle is rotated, the spindle and the damping bounce member generate a frictional force to form a damping effect, thereby providing a reaction force when the wire is released and offsetting part of the gravity of the curtain and effectively slowing down the speed and impact force when the curtain falls. When the curtain is rolled up, the reel links the bearing sleeve to rotate clockwise relative to the spindle, and the spindle and the damping bounce member have no relative movement, and the rotation has no resistance.
