摘要： A lockable corner bracket includes a lockable encapsulated axle pulley which houses one end of a length of cord, with the free end secured to a side bracket. A cord locking mechanism is used to lock the encapsulated axle pulley and prevent unwinding of the cord, or loss of tension, during transport and installation to facilitate do-it-yourself installation. The axle pulley is further configured with a central slot to allow frontal insertion of a roller tube. The corner bracket may be used with a manual roller screen including roller tubes fitted with spring assist systems to facilitate winding and unwinding of the screen, or with roller tubes fitted with a tubular motor to drive rotation of the roller tube.

摘要： A roller shade actuation device includes two actuators arranged in a winding drum, a shaft inserted into the winding drum, and a transmission mechanism. Each actuator includes a housing fixed to the winding drum, a rotary power member arranged in the housing, a driving gear fixed to an output shaft of the rotary power member and coaxial with the output shaft, and a first transmission gear rotatably mounted to the housing and meshed with the driving gear. The actuators are connected linearly in sequence. The driving gear of one actuator adjacent to the transmission mechanism is transmission-matched with and connected to the transmission mechanism, and the driving gears of the remaining actuators are meshed with the first transmission gears of neighboring actuators adjacent to the transmission mechanism. The actuators are connected in series to form an actuator combination through the driving gears and the first transmission gears.

摘要： The present invention provides a constant force multiple spring curtain winding system, including a mounting bracket fixedly connected to a wall, and a revolving drum connected to a curtain, wherein one end of the mounting bracket is connected to a rotating rod through a speed change mechanism, a constant force spring mechanism fixedly connected to the revolving drum is arranged on the rotating rod, and the rotating rod is fixedly connected to a constant force elastic piece in the constant force spring mechanism. According to the present invention, a speed of the revolving drum is adjusted by the speed change mechanism, and the rotating rod rotates at a low speed by the speed change mechanism when the revolving drum rotates at a high speed, thus ensuring that the revolving drum rotates for enough turns to meet a height of the curtain, maximizing a width of the curtain and reducing a counterweight of a lower rail of the curtain; and the requirement on the size of the curtain is met by increasing or decreasing the number of the constant force spring mechanisms, and the curtain is capable of staying at any positions. The constant force multiple spring curtain winding system is novel in structure, simple to operate, wide in application and easy to popularize.

摘要： A system for exerting torque on a shaft includes: a spring assembly having; a spring; a companion member to the spring, wherein at least one of the spring and the companion member is in compression and the other of the spring and companion member is in tension; connecting structure for transmitting a force associated with the spring outside of the gear assembly; and a gear train for connecting the connecting structure to the shaft to apply torque to the shaft. A method of exerting torque on a shaft includes: arranging a plurality of spring assemblies arranged in an array around the shaft, each spring assembly having; a spring; connecting structure for transmitting a force associated with the spring; attaching a gear train to the connecting structure; and configuring the gear train to apply the force associated with the spring to the shaft in the form of torque on the shaft.

摘要： A counterbalancing device for a roller shade having a flexible sheet member and a roller shaft coupled to the flexible sheet member includes a stationary rod extending within the roller shaft, with the rod including a first end and a second end opposite the first end. The counterbalancing device also includes a rod adjuster coupled to the first end of the stationary rod and a spring winder positioned adjacent to the first end of the stationary rod. The rod adjuster is configured to selectively rotate the stationary rod and the spring winder is configured to rotate with the roller shaft. Additionally, the counterbalancing device also includes a spring having a first spring end coupled to the spring winder such that the first spring end rotates with the spring winder, and a second spring end coupled to the stationary rod such that the second spring end rotates with the stationary rod.

摘要： A window curtain includes a rotary tube located in the top rail, and a curtain is connected between the top rail and the bottom rail. A scrolling device is located in the tube and includes a torsion spring mounted to a fixed shaft. A sleeve is connected to the fixed shaft. An adjustment unit is connected to the fixed shaft. The torsion spring is located between the sleeve and the adjustment unit. The adjustment unit includes a housing, a tubular part and a resilient member. The first end of the torsion spring is fixed to the tubular part. The torsion spring is compressed or released by rotating the adjustment unit. The tubular part includes ratchets which are engaged with a pawl in the housing to maintain the tubular part and the torsion spring from rotating reversely.

摘要： A desired range of lift force to raise a window shade is used to select the window shade hardware such as, for example, the optimal LAM. A desired lift force may be 5 pounds for ADA compliance. However, if the user wants to exert less effort to lift the window shade, the user may request an increased lift force of 6 or 7 pounds. Therefore, if a lift force range between 3-8.5 pounds is desired, the system selects the optimal LAM to maintain and guarantee that the lift force required to operate the shades will not exceed the desired range of between 3-8.5 pounds.
