摘要:
First and second lifting and lowering units (21, 22) are connected to first and second shielding members hung from a head rail (13), and a single operating cord (14) drives the first and second lifting and lowering units to lift and lower the first and second shielding members independently. A rotating member (26) is attached to the head rail, and the operating cord is wound around the rotating member. Between a first input shaft (21a) to which the turning force of the rotating member is transferred and a first output shaft (21b) that can lift and lower the first shielding member, a first clutch (31) of the first lifting and lowering unit is provided, and a first stopper (41) is provided in the first output shaft. Between a second input shaft (22a) to which the turning force of the rotating member is transferred and a second output shaft (22b) that can lift and lower the second shielding member, a second clutch (32) of the second lifting and lowering unit is provided, and a second stopper (42) is provided in the second output shaft. A solar radiation shielding apparatus of the present invention lifts and lowers the first shielding member and the second shielding member independently with a relatively simple structure with operation of one operating cord.
摘要:
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).
摘要:
A clutch-brake type roll blind in which a screen is rolled up by means of a spring, characterized in that a pulling cord need not be attached to a weight bar even in a case where the blind is installed on a window which extends from the floor to a portion close to the ceiling. A rotating shaft (14) rotating integrally with a roll (10) is made to protrude from one side of the roll (10) so as to be rotatably supported on one of brackets, and a pulley (22) capable of rotationally driving the roll (10) in a screen pulling-out direction is mounted on the rotating shaft (14) integrally or via a one-way clutch so as to rotate together with the rotating shaft. An operation cord member such as a ball chain (23) is set over the pulley, whereby the ball chain (23) is operated so as to roll up or down the screen (11).
