Therefore, the panel drive sprocket 6 is adapted to rotate coaxially with the power transmission sprocket, and the panel drive sprocket 6 is engaged with the panel connecting chain 4.

A storage rail 9 is a front end on the side of the panel driving sprocket 6 for supporting and running the hanging roller 5 of the panel 3 when the panel driving sprocket 6 passes in the panel storage direction. The rear end side from the side toward the panel storage direction side is gradually arranged to be inclined downward.

Here, the storage rail 9 will be described in more detail. As shown in FIGS. 3, 6 and 7, a mounting main body 10 is formed by removing the vicinity of one ridge line portion of a longitudinal member having a rectangular cross section, and this mounting body 10. A rail main body 11 having a groove-shaped cross section is fixed to the mounting main body 10 along the longitudinal direction of the main body 10 by means such as welding. The mounting main body 10 has a rail main body 11 at a fixing portion 10a that forms one side surface (upper surface) thereof.
Are fixed to each other, and the facing surface (lower surface) of the fixed portion 10a serves as a mounting portion 10b to the rail supporting piece portions 2a and 2b.

Further, the mounting body 10 has a fixed portion 1
Vertical plate portion 10c connecting between 0a and the attachment portion 10b
And a mounting portion 10d which is formed on the side facing the vertical surface plate portion 10c and is mounted on the brackets 2A and 2B, and a downward mounting piece portion 10e is integrally formed on the front end side of the mounting portion 10d. The lower end surface of the downward mounting piece 10e is formed as a rounded lower end surface having the same curvature as the outer peripheral surface of the sprocket support shaft 7. 10f
Is a vertical face plate portion that stands up from the lower end side of the mounting body 10 and the side opposite to the mounting portion 10d.

In the mounting body 10, the rounded lower end surface of the downward mounting piece 10e on the front end side is directly supported on the outer periphery of the sprocket support shaft 7, and the mounting portion 10
By b, the front end side is supported and fixed to the rail support piece portion 2a by bolting or the like, while the rear end side is supported and fixed to the rail support piece portion 2b by bolting or the like, and the appropriate portion of the mounting portion 10d is bolted. Bracket 2A
It has a mounting structure attached to.

Reference numeral 12 denotes a chain guide plate which guides the panel connecting chain 4 to slide from the upper end of the guide rail 1 to the storage rail 9 side along the tooth tip circle of the tooth tip circle of the panel driving sprocket 6. The structure is shown in FIG. 8. The bracket mounting portion 12a mounted to the bracket 2A, the storage rail mounting portion 12b mounted to the side portion 10c of the mounting body 10 of the storage rail 9, and the mounting portions 12a and 12b. And an arcuate sliding contact portion 12c that connects the two.
The pitch circle, that is, the shape along the movement locus of the panel connecting chain 4.

Therefore, the chain guide plate 12 is
While the bracket mounting portion 12a is fixed to the fixed bracket 2C fixed to the bracket 2A by bolting,
The storage rail mounting part 12b is mounted by bolting the main body 1
The mounting structure is fixed to the 0 side portion 10c.

Numeral 13 is a chain separating plate, and when the panel connecting chain 4 meshed with the panel driving sprocket 6 is moved up and down, the claw portion 13a comes into contact therewith to ensure that the panel driving sprocket 6 moves in the panel storing direction. It is something to pull them apart. As shown in FIGS. 3 and 9, the chain separating plate 13 is fixed to the side portion 10c of the mounting body 10 integrally with the chain guiding plate 12 by bolting.

In this way, the mounting body 10 for the storage rail 9
By integrally attaching the chain guide plate 12 and the chain separating plate 13 to the side portion 10c of the above, the front end side of the storage rail 9 can be accurately positioned with respect to the chain guide plate 12 and the chain separating plate 13. Therefore, even if there is an error in the inclination angle of the storage rail 9 on the rear end side, the error can be absorbed.

In FIG. 2, reference numeral 14 denotes a chain separating plate, which prevents the panel connecting chain 4 from coming off from the tooth tips of the panel driving sprocket 6.

Further, an opening / closing device (not shown) is attached to the bracket 2B, and the rotation output of the opening / closing device is transmitted to the sprocket for power transmission through a power transmission mechanism (not shown), whereby the sprocket 6 for driving the panel is moved. It is designed to be rotated.

Reference numeral 15 is a chain tip guide rod which is attached over the brackets 2A and 2B and slidably connects the upper end portions of the panel connecting chains 4, and 16 is rotatably supported on both lower sides of each panel 3. A lower guide rail on which a lower guide roller (not shown) travels, and 17 is a panel guide provided on the bracket 2A to guide the lower guide roller in a predetermined panel moving direction.

Next, the operation will be described. When the panel drive sprocket 6 is driven to rotate clockwise in the figure by the activation of the opening / closing device in the shutter fully closed state in which all the panels 3 are extended between the guide rails 1, the sprocket 6 rotates. The series of panels 3 are moved by the feeding operation of the panel connecting chain 4 by the vertical movement in the series posture along the guide rail 1 from the rail main body 1 of the storage rail 9.
1 is transferred to the horizontal movement in the parallel posture.

At the time of continuous feeding, that is, when the panel 3 passes through the panel driving sprocket 6 in the panel housing direction, the hanging roller 5 of the panel 3 moves onto the rolling surface of the rail main body 11, By traveling on the rolling surface, the panels 3 that have sequentially passed through the panel driving sprockets 6 toward the panel storage direction are stored by the rail body 11 in a suspended state in a parallel posture.

When the panel driving sprocket 6 is driven to rotate in the reverse direction in such a panel housed state, the series of panels 3 are arranged in parallel along the rail main body 11 by the feeding operation of the panel connecting chain 4 by the rotation of the sprocket 6. The horizontal movement of the posture is transferred to the vertical downward movement along the guide rails 1 to close the space between the guide rails 1.

In the above embodiment, the storage rail 9 is used.
Although the case where the storage rail 9 is inclined has been described, the storage rail 9 may be a horizontal rail, and in this case, the same effect can be obtained.

Further, in the chain guide plate 12 described above, for example, as shown in FIG. 10, the bracket mounting portion 12a mounted to the bracket 2A is formed with the guide rail mounting portion 12d so as to be mounted to the guide rail 1. Good. If formed in this way, the relative position of the chain guide plate 12 with respect to the guide rail 1 can be easily set.

[0035]

As described above, according to the first aspect of the present invention, the chain separating plate is attached to the side portion of the storage rail so as to be supported and fixed. Therefore, in view of the relative positional relationship with the chain separating plate. If the mounting position of the storage rail in the storage rail can be easily set and the front end side of the storage rail is accurately positioned with respect to the chain separating plate in this way, and there is a mounting error on the rear end side of the storage rail. Since the mounting error can be absorbed, the storage rail can be easily mounted.

According to the second aspect of the present invention, the chain separating plate and the chain guiding plate are mounted and supported and fixed to the side portions of the storage rail. Therefore, the relative positions of the chain separating plate and the chain guiding plate are fixed. It is possible to easily set the mounting position of the storage rail in relation to the rear end side of the storage rail by accurately positioning the front end side of the storage rail with respect to the chain separation plate and the chain guide plate. When a mounting error occurs, the mounting error can be absorbed, so that the storage rail can be easily mounted.
