Abstract:
A roller shade is provided. The roller shade includes a roller (40); an axle located in the roller; an adjustable counterbalancing mechanism (44) configured to counter balance a rotation of the roller wherein the counterbalancing mechanism is configured to impart a rotational force on the roller and the rotational force is adjusted by rotating the axle; and a locking mechanism (60) attached to the roller and configured to lock the axle at a given angular orientation, wherein the locking mechanism includes a shear pin (62). A method of tensioning a counterbalancing mechanism is also provided. The method includes: mounting the counterbalancing mechanism (44) to a shaft; mounting the lock wheel (54) to the shaft; turning the shaft to tension the counterbalancing mechanism; and inserting a shear pin (62) into a hole (58) in the lock wheel (54) to lock the shaft in place.

본 발명은 이중원단 블라인드의 원단 각도조절 장치에 관한 것으로 더욱 상세하게는 회동구의 삽입홈에 삽입된 4개 및 8개의 볼이 스톱퍼의 가이드홈 내에서 90도 및 45도 회전될 때마다 다수 개의 볼이 순차적으로 구속홈에 구속되므로 전방시트의 개방 각도를 미세한 부분까지 조절할 수 있으며, 조절끈을 사용하지 않아 안전 사고를 원천적으로 방지할 수 있는 것이다.
Abstract:
The invention concerns a method for detecting an unauthorised action on a motorised shutter element, in particular a roller shutter, kinematically linked to an electric driving motor actuated by a control device, which consists in detecting the occurrence of the torque variation on the shaft of the motor powering the shutter element and in triggering an alarm when a torque variation is detected in the absence of motor powering.
Abstract:
A covering for an architectural opening is provided. The covering may include a roller, a shade, and an assembly associated with the roller. The assembly may include a biasing element and a retention element. The biasing element may be operably associated with the roller to selectively rotate the roller. The biasing element may be preloaded. The retention element may be associated with the biasing element. The retention element may be operable to release the preload in the biasing element at an extended shade position.
Abstract:
A fabric fire rated door is described. The door utilizes a fire resistant fabric curtain with an end lock attachment. A tubular steel shaft is driven by an internal tube motor. The shaft is supported to minimize deflection. Single door shafts can also be joined together with a coupler shaft to create infinitely wide doors. The coupler shaft is spring loaded to act as a take up reel for a coupling curtain which will overlap each adjacent single door shaft. All curtains are attached to the same bottom bar. A hood covers the shaft, curtain, and the supports that run across the width of the door. The curtain travels over these horizontal supports as it drops down through the hood opening. The horizontal supports keep the curtain in position for proper seal during a fire/smoke event.
Abstract:
A shading assembly (100) comprising at least one shading vane (120) and at least one vane mounting assembly, wherein the shading vane(120) is configurable in a first shading profile or a second shading profile about a twisting axis, the second shading profile being a twisted profile which is formed by twisting the shading vane of the first shading profile about the twisting axis; and wherein the vane mounting assembly comprises a vane anchoring base(166) which is adapted to hold the shading vane in the first shading profile, the second shading profile, or an intermediate shading profile having an extent of twist about twisting axis which is less than the extent of twist of the second shading profile.
Abstract:
The present invention relates to double fabric blinds and, more particularly, to a device for adjusting a fabric angle of the double fabric blinds, which is capable of finely adjusting an degree of openness of a front sheet, wherein a plurality of balls are sequentially held in a holding groove, e.g., as four or eight balls, inserted into an insertion groove of a rotation component, wherein the plurality of balls are rotated in a guide groove of a stopper by approximately 90 degrees or 45 degrees, thereby improving safety and omitting the use of a conventional string.
