摘要： The present invention relates to a screen rolling device, which includes a winding roller, an inner shaft, at least one metal strip roll and a screen. The inner shaft is located in the winding roller. The metal strip roll is wound around the inner shaft and has a first end and a second end. The first end is fixed to the inner shaft, and the second end drives the winding roller to rotate relatively to the inner shaft. The screen is wound around the winding roller and has a first end and a second end. The first end is fixed to the winding roller, and the second end is a free end. Therefore, the length of the screen pulled down by a user is the desired length and does not need further adjustment.

摘要： A spring drive system useful for window covers is disclosed, which comprises one or more coil spring drives or flat spring drives and the combination whose elements are selected from one or more of a group which includes (1) a band or cord transmission which provides varying ratio power transfer as the cover is opened and closed; (2) gear means comprising various gear sets which provide frictional holding force and fixed power transfer ratios; (3) a gear transmission which provides fixed ratio power transfer as the cover is opened or closed; (4) crank mechanisms; (5) brake mechanisms; and (6) recoiler mechanisms. The combination permits the spring drive force to be tailored to the weight and/or compression characteristics of an associated window cover such as a horizontal slat or pleated or box blind as the cover is opened and closed.

摘要： A door with a moveable window sash and a method of operating the same. The door includes vertical jambs with vertical channels. A window sash is movable in the vertical channels. A retractable screen assembly is attached to the door. The retractable screen assembly includes a roller, a flexible screen attached at a first end to the roller and at a second end to the movable window sash, and a biasing mechanism adapted to apply a continuous torque to the roller. The torque generates a positioning force on the window sash equal to at least 50% of the force of gravity acting on a window sash, such that the window sash can be positioned at an infinite number of locations along the vertical channels.

摘要： A shade positioning system which employs a wrap spring clutch system includes a shade operator, a shade roller, and an idle end bracket for supporting the shade roller when mounted. The shade operator includes a self-lubricating central stud around which a helical coil spring is wrapped, a manually operated pulley mounted on the wrap spring, and a support bushing to ensure positive engagement of the aforementioned elements. The central stud is composed of a plastic or metal, which allows the smooth rotation of the wrap spring around the stud. The tangs of the wrap spring project substantially radially outward from the spring central axis, and are shaped to accommodate for the coefficient of friction between the stud and the spring. A first preferred spring construction allows for decreased spring surface area to contact the stud. A second preferred spring construction allows for an increased spring surface area to contact the stud. Further, the bushing is provided is with a projection which engages the wrap spring due to the weight of the shade. This engagement causes the spring to further grip the stud preventing pulley rotation.

摘要： A hub provided at an end of a roller rotates with the roller. A stationary cap mounted to an axle of the roller is positioned adjacent the hub. A pawl pivots on the cap and is movable to engage gears on the hub. The pawl has two abutment surfaces mounted. The pawl pivots between a first position wherein one of the abutment surfaces engages the geared surface to prevent rotation of the hub in a first direction and a second position wherein the other abutment surfaces engages the geared surface to prevent rotation of the hub in a second direction.

摘要： An operator for a window covering has a stationary member and a hub which is moveable relative to the stationary member when not restrained. Preferably these members are a tube or solid cylinder within a tube. A spring having a selected diameter is fitted between these two generally cylindrical members. A first tang at one end of the spring is attached to the stationary member and a second tang at an opposite end of the spring is attached to a movable member so that one tang can be moved relative to the other tang to increase or decrease the diameter of the spring. The spring is sized and positioned so that the spring will press against the inside surface of the hub when in a relaxed condition. When the tangs of the spring are moved relative to one another to reduce the diameter of the spring, the spring does not restrain movement of the moveable member. In a present preferred embodiment there is a roller attached to the hub at one end. Alternatively, a spool about which lift cords are wound is attached to the hub. A counteracting spring may be attached to the roller or spool.

摘要： A roll screen apparatus improved in operation and manufacturing, wherein the winding up and down of the roll screen are effected in such a manner so that the rotation of the pulley, by the pulling down of the operation cord, is transmitted to the screen winding pipe, and wherein the stop of the screen is effected by disengaging the transmission from the screen winding pipe to the pulley. The improved apparatus is characterized by providing a clutch device and a disengagement device. The clutch device is only transmissive of the rotation of the pulley to the screen winding pipe, and the disengagement device disconnects the engagement between the pulley and the screen winding pipe and maintains such disconnected condition.

摘要： A clutch-brake type roll blind is provided with a wind-up spring for rolling up a screen on a tube and a weight bar free from a pulling string, being suitable for use with a tall window extending from floor to ceiling. The roll blind includes a rotary shaft fitted in the tube for rotation therewith and projecting therefrom, a pulley rotatably mounted on the rotary shaft, and an endless ball chain drivingly hung down from the pulley. The pulley can rotate the tube only when the ball chain is pulled down in the direction in which the screen is rolled down from the tube.

摘要： An improved winding apparatus for a roller blind is disclosed. The winding apparatus includes a clutch mechanism provided between the winding roller and the cord pulley for transmitting rotation of the pulley to rotation of the winding roller. The clutch mechanism is arranged to prevent the urging mechanism from rotating the winding roller when the cord is not handled. It also allows the pulley to rotate a predetermined angle in a screen lifting direction when the cord is operated to lift the screen. At this point, the urging mechanism is permitted to rotate the winding roller in the screen lifting direction. Additionally, when the pulley is rotated by the cord in a screen lowering direction the pulley is first allowed to rotate freely for a predetermined angle. Thereafter, the screen lowering motion of the cord is transmitted through said pulley to said winding roller to lower the screen.
