A shutter locking assembly that has a bolt carriage with a bolt slidingly engageable with the bolt carriage and a biasing (actuator) means operatively connected to the bolt member and the bolt carriage. The bolt carriage is inserted into a cavity of a shutter slat, and the action of moving the shutter slat between an up (open) position and a down (locked) position, causing the bolt to be moved between an extended position and a retracted position. When the shutter slat is in a down (locked) position the bolt engages with a bolt receiving opening adjacent to the shutter slat, and when in an up (open position) the bolt is retracted

A releasable locking mechanism comprising a lock mode, and an unlock mode; a handle and at least one resilient member mountable between the handle and a shaft, wherein the resilient member biases the mechanism to the lock mode when the mechanism is at rest; and actuation of the handle by a user releases the mechanism from the lock mode to the unlock mode, allowing rotation of the handle and the at least one resilient member about the shaft.

The present invention relates to a roller blind and a control device thereof. The control device comprises a reeling mechanism, a solenoid valve, a push mechanism, a front cap, and a damper. After the solenoid valve is energized, the solenoid valve drives the push mechanism to push against the front cap so as to separate the front cap from an engaging portion of the reeling mechanism, and the reeling mechanism is not subject to a resistance of the damper. A curtain fabric is not affected by the resistance of the damper and can be quickly lowered by gravity.

An operating system for an architectural covering is provided. The operating system allows at least three modes of operation of an architectural covering. A transmission may be included between an input assembly and an output drive member, and the transmission may be selectively engaged to place the operating system into one of the at least three modes of operation. The operating system may include a first drive section including an input, a second drive section including an output, and a control mechanism arranged to selectively lock an element of the first and second drive sections to control movement of the output of the operating system upon actuation of the input. A shift lock is also disclosed herein. In use, the shift lock operates to restrict shifting operation of the operating system from one operating mode to another.

A speed regulating assembly for coupling to a roller tube for regulating a deployment speed of a covering of an architectural-structure covering is disclosed. The speed regulating assembly may include a detachable adapter for enabling a singular sized speed regulating device to be used regardless of the size of the roller tube. That is, by utilizing a detachable adapter for coupling to the roller tube, any change in the size of the roller tube only requires a different sized adapter. In addition, the speed regulating assembly may be configured so that during covering retraction, the speed regulating assembly is disengaged so that any input rotation from the roller tube is not transmitted to the speed regulating device. However, during covering deployment, the speed regulating assembly is engaged so that any input rotation from the roller tube is transmitted to the speed regulating device thereby regulating the speed of covering deployment.

A door curtain anti-dropping device for a rolling door is provided. The device comprises a worm shaft connected to the output shaft of the door operator, and a drive shaft comprising a limiting disc with through holes. The worm wheel having receiving slots is fixed on the drive shaft to mesh with the worm. The driven wheel is disposed adjacent to the limiting disc. Baffle plates designed to cover the through holes and receiving slots extend from the driven wheel. Plural latching pins stored with spring potential energy are compressed by the baffle plates and retained in the through holes and receiving slots. When the worm wheel is excessively worn and dislocated from the driven wheel, the baffle plates are moved to allow the latching pins to spring out and insert into the notches of the front cover, thereby lock the worm wheel and prevent the winding shaft from rotating.

A shift lock is also disclosed herein. In use, the shift lock operates to restrict shifting operation of the operating system from one operating mode to another.

A vehicle cover assembly has a body and a lock device. The body has a housing, a reeling device, and a cover fabric. The reeling device is mounted in the housing and has a reeling axle. The cover fabric is connected with and is selectively reeled around the reeling axle. The lock device has a casing, a pushing rod, and a lock cylinder. The casing is mounted on the housing. The pushing rod is moveably mounted through the casing and has an end selectively engaged with one end of the reeling axle. The lock cylinder is mounted in the casing and is selectively engaged with the pushing rod. When the lock cylinder is engaged with the pushing rod, the pushing rod is engaged with the reeling axle.

A device (1) is described for stopping, releasing and restoring the position of roller-type window nets (3, 48), comprising: a fixing shaft (13) having a coupling groove (15) formed in a front external circumferential surface thereof and an insertion groove (16) formed in a rear surface thereof; a ball rotor (18) inserted into the fixing shaft (13) and coupled to the external circumferential surface of the fixing shaft (13), including a front portion coupled by means of a spring (30) and having a conveying groove (20) formed in a surface thereof for conveying a ball (40) and a guide jaw (38) formed in a central part thereof, wherein the ball (40) is inserted into the conveying groove (20); and an outer rotor (42) coupled to the conveying groove (20) via the ball (40) and having a rotation groove (44) formed in an internal circumferential surface thereof, wherein the ball (40) is coupled to the rotation groove (44) to rotate.
