A window shade includes a top box, a mediate bar, a bottom bar and a shade connected between the mediate bar and the bottom bar. A first scrolling unit and a second scrolling unit are located in the top box, and each are cooperated with a movable unit, a resilient member and a fixed member. The resilient member is connected between the movable unit and the fixed member. Each of the first scrolling unit and the second scrolling unit has a first roller and a second roller, and each of the movable unit has a third roller and a fourth roller. The first cords of the first scrolling unit are connected to the mediate bar. The second cords of the second scrolling unit extend through the mediate bar and are connected to the bottom bar. The first and second cords meet the requirements of a longer shade.

The present invention concerns a motorized door comprising an array of n detection cells distributed along the length of the leading edge, capable of detecting the presence and distance, x, from said detection cell of a body positioned between said detection cell and a distal transverse edge. The detection cells are coupled to a CPU which triggers different actions during the closing of the shutter, depending on the proportion, P=n1/n of the number, n1, of detection cells identifying the presence of a body at a same time located at a distance, xxs, wherein xs is a predefined safety distance. (a) if PPs, wherein Ps is a predefined safety proportion, the detected body is considered as an accidental obstacle and the CPU is programmed to instantly stop the movement of the shutter; (b) if P>Ps, the CPU considers that the detected body is a distal transverse edge defining the end of the closure run, and orders to decrease the closing speed of the shutter until the leading edge contacts the distal transverse edge.

The present discloses an automatically locked retractable protective door sill, including a retractable curtain assembly, a scroll assembly, an upper fixing base and a lower fixing base, a dial mechanism and a locking mechanism are arranged in the upper fixing base, the locking mechanism includes a hydraulic rod capable of retracting at a fixed time, and the hydraulic rod is connected to the dial mechanism; the sliding base is connected to the hydraulic rod, and the hydraulic rod drives the sliding base and drives the linkage base to reset automatically, so the automatic locking of the locking mechanism is achieved, and then the scroll assembly is locked. The whole device has a simpler structure and more convenient operation, the dial button may be manually pushed to return for locking after not reaching the set time, so as to prevent children opening the door sill during an automatic locking process.

An adjustable architectural frame uses multiple length-adjustable support beams and a pair of panel-connecting mechanisms to function as a framework for mounting architectural panels of varying size and construction. The support beams of the adjustable architectural panel include width-adjustment beams and height adjustment beams. The width-adjustment beams and the height-adjustment beams are preferably telescopic beams that have lengths which can be increased or decreased. These beams are terminally connected to create a quadrilateral frame that has physical dimensions which can be modified as a user desires. Additionally, the adjustable architectural panel makes use of the pair of panel-connecting mechanisms to mount various types of architectural panels onto the adjustable architectural frame. For example, the pair of panel-connecting mechanisms can be tracks along which an accordion door runs. Alternatively, the pair of panel-connecting mechanisms can be rods which support a sheet of material that is played out from a reel.

A window shade includes a reel and an aperture control module respectively assembled with a head frame, and a panel assembly including transversal vanes respectively connected with two panels. The reel is rotatable to wind and unwind the panel assembly. The aperture control module includes a positioning arm connected with a rubbing roller, and is operable to rotate the rubbing roller relative to the positioning arm and to displace the positioning arm and the rubbing roller between two positions, the rubbing roller being displaced away from a sidewall of the head frame in a first position and pressing the panel assembly against the sidewall in a second position, the rubbing roller being further rotatable relative to the positioning arm in the second position to cause relative sliding between the two panels for switching the panel assembly from a closed state blocking light passage to an open state allowing light passage.
