Abstract: A sunlight-shielding device includes two one-way clutches characterized by a short overall length, compact size, simple structure, and fewer parts for a sunlight-shielding device in which two shielding materials suspended from a head box can be switched using a single-loop up/down operation cord. Each one-way clutch includes has an input disk, input plate, top plate, and output drum provided on a center pin in a rotatable manner such that when the input plate rotates in a specified direction due to the rotation from the input disk, an engagement part of the top plate projects along a guide groove and engages with an engagement projection strip of the output drum, to transmit the rotation from the input disk to the output drum.

Abstract: First and second lifting and lowering units are connected to first and second shielding members hung from a head rail, and an operating cord drives the units to lift and lower the shielding members independently. An operating cord is wound around a rotating member. Between a first input shaft to which the turning force of the rotating member is transferred and a first output shaft that can lift and lower the first shielding member, a first clutch of the first lifting and lowering unit is provided, and a first stopper is provided in the first output shaft. Between a second input shaft to which the turning force of the rotating member is transferred and a second output shaft that can lift and lower the second shielding member, a second clutch of the second lifting and lowering unit is provided, and a second stopper is provided in the second output shaft.

Abstract: Upper ends of the first fabric and the second fabric are attached to the head rail, respectively, and the first lift cord and the second lift cord suspended from the head rail in a liftable manner are coupled to the first fabric and the second fabric, respectively. The first lift cord is routed into a rear side of the first fabric and the second lift cord is routed into a rear side of the second fabric so as to come over an upper end of the second fabric. An extension member is provided so as to extend downwardly along with a lower edge of a rear portion of the head rail, and the upper end of the second fabric is attached to a front surface of the extension member.

Abstract: A curtain wave forming mechanism is constituted of curtain runners and a curtain hook attached to each curtain runner and hanging a curtain. The curtain hook is a separate body from a curtain tape and has a flat plate-like body section inserted into a hook insertion hole section of the curtain tape perpendicular to the length direction of a curtain rail, a foot section bent upward at the lower end central part of the body section and hooked to the hook insertion hole section, a shaft section extending from the upper central part of the body section, and a head section for insertion, formed on the head of the shaft section. A curtain runner has a body running in the curtain rail, a leg section hanging from the curtain rail, a hollow-cylindrical body supported at the leg section so as to be rotatable about the vertical axis of the leg section, and a bearing section for an insertion hook, supported at the hollow-cylindrical body.

Abstract: A lifting cable winding mechanism of a solar radiation shielding device capable of uniformly winding lifting cables for lifting solar radiation shielding materials on the peripheral surfaces of winding drums and minimizing the extra lengths of the lifting cables remaining in a head rail when the solar radiation shielding materials are lowered to a lower limit, wherein a case (2) is fixed in the head rail (1), the winding drums (4) are fitted to a drive shaft (3) axially passed through the inside of the head rail (1) so as to be rotated integrally with each other, slits (6) are provided at the bottom part of the case (2), rings (7) are fitted to the winding drums (4) so as to be rotated integrally with each other and slidably moved in axial direction, guides (11) suspended from the bottom part openings (10) of the head rail (1) are formed at one end parts of the case (2), and the tips of the lifting cables (5) inserted from the slits (6) into the case (2) through the guide (11) are fixed to the rings (7).

Abstract: 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.

Abstract: According to the present invention, there is provided an apparatus for lifting and tilting slats in a venetian blind, comprising: a head box; a rotating shaft; ladder drums rotating together with the shaft; drum holders for supporting the ladder drums; ladder rings of an open ring shape and fitted around each of the ladder drums; ladder cords being put on, and secured to, each of the ladder rings; lifting drums; lift cords, wound around each of the lifting drums; slats; and elements for stopping the rotation of the shaft.

Abstract: A manually and automatically operable curtain is provided with an electric motor, a planetary gearing of which the sun gear is fixed to the output shaft of the motor, a driven gear engageable with the planet gear of the planetary gearing, a cord pulley fixed to the driven gear for drawing the curtain, and an electric control system including a motor-reversing device. The rotation of the motor is transmitted to the cord pulley through the intermediary of the planet gear when the motor turns. Responsive to a signal to stop the motor, the motor-reversing device reverses the motor for a very small time so as to disengage the planet gear from the driven gear. Thus, the curtain is easily operated by hand without receiving the rotational resistance of the motor.

Abstract: A curtain runner comprising a runner body (10) made of a synthetic resin previously mounted in a curtain rail (40) with a curtain rod (30) vertically mounted to and coupled with the runner body. The rubber body is shaped in a box with a bore (15) in the bottom wall. The rod has a head (31) larger in diameter than the other portion thereof. A sleeve (20) is fitted from the bottom in the bore and provided with top and bottom flanges (21, 22) larger in diameter than the bore. The axial hole (24, 26) of the sleeve except for the top portion (25) thereof, is larger in diameter than the head. The sleeve has the upper portion thereof formed with a plurality of slits (23) to contract the top flange smaller than the bore when it is fitted in the bore and expand the top portion of the axial hole larger than the head when the head passes through the sleeve.
