Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a panel body of a panel shutter, and more specifically, the present invention relates to a panel body of a panel shutter. A panel shutter that allows the panel body to be easily removed and replaced in the event that the panel body is damaged, even when the panel body is installed facing the guide rails set up on both the left and right sides of the The present invention relates to a panel body.

[Conventional technology]

Conventionally, in this type of panel shutter,
In order to facilitate the replacement of a damaged panel body, for example, as shown in Fig. 5, the panel body a is made narrower than the opposing spacing between the guide rails b, which are erected on both the left and right sides of the building opening. At the same time, end metal fittings c were connected and fixed to both ends of the panel body a via fasteners d, and the shutter curtain was installed with the end metal fittings c facing inside the guide rail b.

However, since a shutter curtain installed in this manner requires end hardware c in addition to the panel body a, it is difficult to increase the number of parts of the shutter curtain, and it is difficult to maintain airtightness, which is the original function of the shutter. In addition, the appearance of the end of the shutter curtain was unnatural due to the different shapes of the panel body a and the end hardware c, and was not desirable in terms of design.

[Problem that the invention attempts to solve]

The present invention was devised in view of the above-mentioned actual situation and to eliminate the drawbacks of the conventional method.The purpose of this invention is to construct a shutter curtain with only a panel body, eliminating the need for end hardware. Moreover, even if the shutter curtain is installed with both ends facing inside the guide rail, if the panel body becomes damaged, the panel body can be easily and easily removed and replaced. , reducing the number of parts in the shutter curtain and improving work efficiency.
Furthermore, it is an object of the present invention to provide a panel body for a panel shutter that can exhibit excellent functional beauty in terms of design.

[Means for solving problems]

The present invention employs the following technical means to solve the above problems.

That is, roller shafts are inserted into both ends of the upper frame of a long panel body through insertion holes, and a plurality of panel bodies are vertically connected by a roller chain attached to the roller shaft to form a shutter curtain. At the same time, a panel body is removably fixed to the roller shaft, and furthermore, a panel body is provided at the end of the panel body in the longitudinal direction of the roller chain at a depth extending from the edge to the insertion hole in the longitudinal direction. A cutout groove is formed that is wider than the width of the groove.

[Effect]

Therefore, according to the present invention, even if the shutter curtain is installed with both ends facing inside the guide rail, if the panel body is damaged,
After releasing the fixed state between the panel body and the roller shaft, when the panel body is slid along either the left or right roller shaft, the end of the slid panel body passes through the notch groove. As it passes through the roller chain and moves to the bottom wall side of the guide rail, the end of the panel body on the other roller shaft side comes out of the guide rail, so the panel body can be easily and easily removed and replaced. .

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

That is, in FIGS. 1 to 4, 1 is a panel shutter, and the panel shutter 1 includes an upper frame 3 of a plurality of elongated panel bodies 2 arranged at predetermined intervals in the vertical direction. The roller chain 5 is connected in a series with a roller chain 5 attached to a roller shaft 4 which is fitted through fitting holes 3a formed in a cylindrical shape at both ends of the roller. And the above upper frame 3
is fixed to the vertical stile 2a of the panel body 2 via screws 2b. 6 is a roller rotatably supported on the roller shaft 4. The panel body 2 is detachably fixed to a stepped portion 7 formed on the roller shaft 4 via screws 8.

As clearly shown in FIG. 3, the upper stile 3 of the panel body 2 has a width wider than the width of the roller chain 5 in the front-rear direction at a depth extending from its edge in the longitudinal direction to the insertion hole 3a. A notch groove 9 is formed at the end of the panel body 2, and the end of the lower stile 3b and the outer surface side of the cross section of the vertical stile 2a are also formed in a corresponding groove shape. This notch groove 9 may be formed at both the left and right ends of the panel body 2, or may be formed at either the left or right end. Further, the shape of the notch groove 9 is not limited to the U-shape in plan view as in the embodiment, but is essentially wider than the front and rear width of the roller chain 5, and the shape of the notch groove 9 is not limited to the U-shape in plan view as in the embodiment. When the panel body 2 is released from the fixed state with the shaft 4 and is slid along one roller shaft 4, the end of the panel body 2 on the other roller shaft 4 side corresponds to the distance of movement. It may have any shape as long as it can come out of the guide rails 10 erected on both the left and right sides of the building opening.

11 is a shutter case connected to the upper end of the guide rail 10, and the shutter case 1
An induction sprocket 13 is coaxially supported on the left and right side plates 12 of the roller chain 1 on the inside thereof and coaxially with a drive sprocket (not shown), and the extra length of the roller chain 5 is engaged with the induction sprocket 13. . 14 is the left and right side plate 1 of the shutter case 11
The storage rail 14 is a storage rail disposed horizontally inside the panel body 2, and the storage rail 14 rolls a roller 6 supported on the roller shaft 4 of each panel body 2, which moves upward in conjunction with the rotation of the induction sprocket 13. By moving the panel bodies 2, the panel bodies 2 are guided and moved in the lateral direction in a state in which they are lined up in parallel.

Since the present invention is constructed as described above, a part of the panel body 2 constituting the shutter curtain 1 is
If the shutter curtain 1 is damaged over time or accidentally and needs to be replaced, each panel body 2 constituting the shutter curtain 1 is rolled up a little to maintain a predetermined interval in the vertical direction, and then the panels that require replacement are After removing the screws 8 fixing the body 2 and the roller shaft 4, as shown in FIG. When the panel body 2 is slid along either the left or right roller shaft 4, the end of the slid panel body 2 passes through the roller chain 5 through the notch groove 9, and is placed on the bottom wall side of the guide rail 10. As it moves, the end of the panel body 2 on the other roller shaft 4 side comes out of the guide rail 10, so if the screws 8 are released in the same way, the shutter curtain 1 can be installed with both ends facing inside the guide rail 10. Even if the panel 2 is installed, the panel 2 can be easily and easily replaced.

In this case, for example, as in the embodiment shown in FIG.
A cover body 16 is detachably fixed in the vertical direction to the opening side edge of the guide rail 10 via screws 17 so that the facing interval between the two can be adjusted wide and narrow.
If the shutter curtain 1 is opened and closed with the shutter curtain 6 fixed, and the panel body 2 is damaged and needs to be replaced, the cover body 16 can be removed and the distance between the guide paths 15 facing each other can be widened. , the replacement work of the panel body 2 can be performed even more easily.

[Effect of idea]

In short, according to the present invention, the shutter curtain is constructed only from the panel body, eliminating the need for end hardware, and even when the shutter curtain is installed with both ends facing inside the guide rail, the panel body If the panel body is damaged and needs to be replaced, the panel body can be easily removed and replaced by simply disassociating the roller shaft, and by eliminating the need for end hardware, the shutter curtain The number of parts can be reduced and work efficiency can be improved.
Furthermore, since the shutter curtain is composed of panels of the same shape, it can exhibit functional beauty in terms of design, and has extremely useful practical effects.
