Definitions
- the present invention relates to an improvement of a roll plane in which a screen is manually pulled down and a screen is wound by a spring.
- Roll blinds in which the screen is manually pulled down and wound by a spring are known from Jikken Sho 6 3-4 1 5 1 6 and Jikkoku 11-2 6 8 7 1.
- This known blind includes a roll that winds a screen, a fixed shaft that rotatably supports the roll at one end side, a spring that is interposed between the fixed shaft and the roll, and a clamp that is also interposed between the fixed shaft and the roll. And a latch brake.
- the clutch brake When the weight bar attached to the free end of the screen is pulled down, the clutch brake is released, the roll rotates and the screen descends, and when released, the clutch brake enters and the screen stops at that position. Then lower the screen a little and release it, the brakes on the clutch brake are released and the screen is wound up by the spring.
- the screen lifting speed is reduced by the reduction mechanism that is interposed between the fixed shaft and the roll.
- a clutch / brake is known from Japanese Examined Patent Publication No. 6-3,349,500, and a speed reducer is known by Japanese Utility Model Publication No. 1-268711.
- the present invention has been made to solve this problem, and an object of the present invention is to provide a roll blind that does not require a pull-down string to be attached to a weight bar. Disclosure of the invention
- the present invention relates to a roll that winds a screen, a fixed shaft that rotatably supports one end of the roll, a clutch brake that is interposed between the roll and the fixed shaft, and an intermediary between the roll and the fixed shaft. And a spring for rotating the roll in the screen winding direction, a rotary shaft protruding from the other end of the roll and integrally rotatably connected to the roll, and a pair of pluggage bearings for the fixed shaft and the rotary shaft.
- a pulley that can drive the roll to rotate is provided on the rotary shaft, and the endless operation string that hangs down to a predetermined position is hung on the pulley, and the operation string can rotate the roll in the screen descending direction. I have done so.
- the combination of endless operation string and pulley may be any combination of cord and pulley, belt and belt car, rope and rope car, pole chain and pulley.
- the roll blind of the present invention can operate the screen by both the wheel bar and the operation string, the screen is different from the conventional one which is operated only by the wheel bar. Even when reaching from the ceiling to the ceiling, it is not necessary to attach a pulling string to the weight bar, which is a hindrance when lowered.
- the one in which a one-way clutch is interposed between the pulley on which the operation string is applied and the roll on which the screen is wound is the loop-shaped operation string on the screen pull-out side. There is no risk of unreasonable force acting on the roll blind clutch brake even if the side opposite to is pulled forcefully.
- FIG. 1 is a front view showing a cross section of a main part of a roller blind according to an embodiment of the present invention
- Figure 2 is a cross-sectional view taken along the line I I -I I in Figure 1.
- FIG 3 is an exploded perspective view of the one-way clutch in Figure 1
- FIG. 4 is a view corresponding to FIG. 1 of another embodiment, and the present invention will be described based on the embodiment shown in the drawing.
- the fixed shaft 13 is inserted into the roll 10 from one end and the rotary shaft 14 is inserted from the other end.
- the fixed shaft 13 is fixedly supported by a bracket 15 on one end side, and the rotating shaft 14 protruding from the other end side is rotatably supported on a bracket 16 on the other end side.
- the fixed shaft 13 extends inside the roll 10, and the fixed part of the reduction mechanism 17 is attached to the tip of the fixed shaft 13.
- the rotating part of the reduction mechanism 17 is integrally connected to the inner circumference of the roll 10 and rotates integrally with the mouth 10. Attach the end piece 19 to the inner surface of the roll 10 at one end.
- the fixed side of the clutch brake 18 is externally fitted and fixed to the fixed shaft 13, and the rotating side of the clutch brake 18 is connected to the inner peripheral surface of the end piece 19.
- the spring 21 is loosely fitted to the fixed shaft 13, and one end of the spring 21 is fixed to the tip of the fixed shaft 13 and the other end is fixed to the end piece 19 of the hole 10.
- the clutch / brake 18 is the same as that described in Japanese Patent Publication No. 6-3-3495.
- the configuration up to this point is the same as the conventional clutch break type roller blind that winds the screen with a spring.
- a pulley 22 is rotatably fitted on a rotating shaft 14 protruding from the other end of the roll 10.
- the endless pole chain 23 is hung on the wheel 22 and the ball chain is hung down to a position where it is easy for the user to operate.
- the end piece 20 is integrally mounted on the inner peripheral surface of the other end of the roll 10, and the rotary shaft 14 is connected to the end piece through a key 30 and a key groove 31 so as to rotate integrally.
- the key 30 and the key groove 31 diametrically extend the inner ends of the end piece 20 and the rotary shaft 14, respectively, and are detachably connected to each other.
- a one-way clutch 24 consisting of a coil spring is provided between the pulley 22 and the rotary shaft 14.
- the roll blind of the present invention unlike the conventional one, does not need to be attached with a drawstring on the weight bar 12. As shown in Fig.
- the rotary shaft 14 includes an outer end shaft portion 25 that fits in a bracket, a flange portion 26 that regulates the outer end surface of the pulley 22, a central shaft portion 27 that fits the pulley 22, and a one-way clutch 24. And an inner end shaft portion 28 into which the coil spring of FIG.
- the inner end shaft portion 28 of the rotary shaft 14 has a key groove 31 at the tip for coupling with a key provided on the inner circumference of the end piece 20, and the outer diameter is smaller than the central shaft portion 27.
- the hollow shaft portion 31 of the pulley 22 extends to the inner end shaft portion 28 of the rotary shaft 14 and surrounds the coil spring of the one-way clutch 24 mounted on the inner end shaft portion 28.
- An axial slit 33 is formed on the hollow shaft portion 32 of the pulley 22, and the one end 34 of the coil spring of the one-way clutch 24 is inserted into the slit.
- the coil spring of the one-way clutch 24 is wound when one end 34 thereof is rotated in the screen withdrawing direction, and is wound so as to be loosened when it is rotated in the opposite direction.
- the coil is wound around the inner end shaft 28, and the pulley 22 and the rotating shaft 14, that is, the roll, rotates integrally. Then, when the pulley 22 is rotated in the opposite direction, the coil is wound by the slit 32. Since the spring is slack, the pulley 22 spins on the rotating shaft 14 and cannot rotate the roll.
- the coil spring of the one-way clutch 24 is loosened, so that the one-way clutch is disengaged, the rotary shaft 14 or the roll 10 is stopped, and the pulley 22 is idle.
- the one-way clutch in this embodiment is of the coil spring type, the one-way clutch is not limited to the coil spring type, and one-way clutch of other type can be used.
- the pulley 22 rotates with the roll unless resistance is applied to the pole chain, but when the pole chain is stopped and resistance is applied, the one-way clutch 24 The coil spring of the is relaxed, the pulley 22 does not rotate, and it stops together with the ball chain.
- the reduction gear mechanism and the one-way clutch are both omitted, and the other end piece 20 fixed integrally to the roll 10, the rotary shaft 14 bearing on the bracket 16, and the ball chain 23 are provided.
- the hanging pulley 22 may be integrally formed. In this case, since the ball chain 23 always travels while the roll 10 is rotating, it is possible to suppress the rising speed of the screen 11 by manually adjusting the travel of the pole chain 23.
- the user should always hang the Since the screen 11 can be moved up and down by operating the routing 23, even if the weight bar 12 is installed in a window that rises to a high position that is out of reach, it is not necessary to attach a drawstring to the weight bar 12.
- the roller blind of the present invention is used for manually adjusting the shading of a building window or the like, and is particularly suitable for adjusting shading of a high window reaching from a floor to a ceiling.
