Abstract

PURPOSE:To open and close a curtain by remote control by increasing a stroke of a reciprocating motion driving device by a gear and opening and closing a movable shielding member. CONSTITUTION:When an injection is executed to a hydraulic cylinder, a rod 21 expands, a driving belt running member 6 slides a sub-frame part 5 of a frame and a driving belt 4 fixed to the driving belt running member 6 runs. As a result. a driving pulley 3 rotates, and a large gear 13 provided in the same shaft 12 rotates. Accordingly, a small gear 15 rotates and a driven pulley 8 rotates. A movable shielding member fixture 11 fixed to a driven belt 9 slides a main rail 10 and a curtain is closed. On the contrary, by executing the injection in the direction in which the rod 21 of the hydraulic cylinder contracts, the curtain 27 is opened. A gear ration of the small gear 15 and the large gear 13 is 1:2, and a diameter ratio of the driving pulley 3 and the large gear 13 is 1:2, therefore, a running distance of the curtain 27 of four folds of a stroke of the hydraulic cylinder is obtained. Opening and closing can be executed by remote control with an inexpensive device.

And a pinion gear 15 mounted on.

The frame 2 has a front frame 16 and a rear frame 17, is parallel to each other, and is formed to have a length corresponding to the length of a window frame in which the curtain is used. As shown in FIG. 2, the front frame 16 has a flat plate shape, a central portion is inclined rearward, and a U-shaped sub-rail portion 5 is horizontally provided on the upper portion. Further, a main rail portion 10 bent at a right angle is projectingly provided on the lower portion so that the U-shaped ends are vertically opposed to each other.

The rear frame 17 has a flat plate shape, and an auxiliary rail portion 5 which is the same as that of the front frame 16 projects from the upper portion thereof, and a main rail portion 10 which is the same as that of the front frame 16 projects from the lower portion thereof.

One of the drive pulleys 3 is provided substantially in the center of the frame 2, and the other one is provided near the end of the frame 2. A drive belt 4 is wound around these drive pulleys 3 and 3.

The drive band traveling member 6 has a sliding member 18 and a cylinder mounting member 19, as shown in FIG.

The sliding member 18 has a flat plate shape, and both sides thereof are freely fitted into the auxiliary rail portion 5 of the front frame 16 and the auxiliary rail portion 5 of the rear frame 17 so as to be slidable. Then, a mounting plate 20 is attached to the lower surface of the sliding member 18, and the drive belt 4 is sandwiched between the mounting plate 20 and the sliding member 18 to attach the mounting plate 20 to the sliding member 18. The drive belt 4 is fixed to the drive band traveling member 6 by being attached to the lower surface. Also, the cylinder mounting part 1
9 is erected on a sliding member 18, and a cylinder mounting portion 19 is mounted with a rod 21 of a hydraulic cylinder 7 provided above the front frame 16 and the rear frame 17.

The driven pulleys 8 and 8 are the frame 2 respectively.
The driven belt 9 is mounted near the end of the driven pulley 8 and has a driven belt 9 wound around it.

As shown in FIG. 3, a plurality of movable shield member attachments 11 are provided (determined by the length of the curtain).
Each is provided with a mounting body 22 and two sets of wheels 23.

A mounting plate 24 is mounted on the upper surface of the mounting body 22. The mounting plate 24 and the mounting body 2 are attached to each other.
The driven belt 9 is sandwiched between the two and the mounting plate 24 is mounted on the upper surface of the mounting body 22, so that the driven belt 9 is fixed to the movable shield member mounting tool 11. A shaft 25 extends through the central portion as shown in FIG. 3, and wheels 23 are mounted on the shaft 25.
The wheels 23, 23 ... Are fitted into the main rail portion 10 of the front frame 16 and the main rail portion 10 of the rear frame 17. Further, a hanging portion 26 is formed in the lower portion of the mounting body 22, and a hook of the curtain 27 can be hung on the hanging portion 26.

As shown in FIGS. 1 and 4, the small gear 15 is integrated with the driven pulley 8 and is inserted into the shaft 14, and the large gear 13 is, as shown in FIGS. 1 and 2, the drive pulley. The shaft 12 is adapted to rotate integrally with the shaft 3.
Has been inserted into. The tooth number ratio between the small gear 15 and the large gear 13 is 1: 2.

Reference numeral 28 indicates a tension pulley. Next, the operation of the opening / closing device 1 will be described. Now, assume that the curtain 27 shown in FIG. 1 is moved in the direction of arrow P. First, when water is injected into the hydraulic cylinder 7 through a pipe (not shown), the rod 21 extends, and the drive belt traveling member 6 slides on the sub rail portion 5 of the frame 2 and is fixed to the drive belt traveling member 6. Runs. Then, the drive pulley 3 rotates, and the large gear 13 provided on the same shaft 12 as the drive pulley 3 rotates. Therefore, the small gear 15 rotates and the driven pulley 8 rotates. And
The driven belt 9 travels and the movable shield member attachment 11 fixed to the driven belt 9 slides on the main rail portion 10 of the frame 2 to close the curtain.

When the curtain 27 is opened, the rod 21 of the hydraulic cylinder 7 is poured in the direction of contraction in the opposite direction, so that the rod 21 contracts and the movable shield member attachment 11 travels in the direction of opening the curtain 27. Two
7 can be opened. In the present embodiment, the gear ratio of the small gear 15 and the large gear 13 is 1: 2, and the diameter ratio of the drive pulley 3 and the large gear 13 is 1: 2.
A double traveling distance of the curtain 27 can be obtained. Therefore,
By changing the tooth number ratio of the small gear 15 and the large gear 13 and the diameter of the drive pulley 3, it is possible to obtain the traveling distance of the curtain 27 that is twice the tooth number ratio of the stroke of the hydraulic cylinder 7.

In this embodiment, the drive wheel and the drive belt are pulleys and belts, but they may be sprockets and chains, and the reciprocating drive device is a hydraulic cylinder, but may be an air cylinder or a hydraulic cylinder. Although the movable shield member is a curtain, it may be a shutter, a skylight or the like, and is not limited to these.
