Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a lateral shift prevention structure for a panel body in a panel shutter attached to an opening of a building.

[Problems to be Solved by Prior Art and Invention] Generally, in this type of panel shutter, each panel body is connected by a connecting chain, and when the connecting chain is unwound, the preceding panel body is operated. By grounding and contacting the grounded panel body upper edge with the subsequent panel body lower edge,
It is known that the opening is closed. In this case, the adjacent upper and lower panel bodies are made to contact each other by the male and female fitting method so that the panel surfaces are prevented from being displaced inward and outward. However, with this product, the vertical and middle frames of the panel body are not linear in the vertical direction, and they are displaced to the left and right, which is not desirable for appearance, and furthermore, the connection chain is subjected to an unreasonable load and is connected. Has the drawback of being damaged.

Therefore, it is conceivable to provide a lateral deviation prevention member on the panel body. In this case, in order to prevent lateral deviation of the panel body, the applicant has already filed Japanese Patent Application No. 59-193379 (No. 61-107884). Practical application Sho 60-110716
No. 62 (Actual No. 62-19390), the former one has a positioning pin protruding from the lower frame fitted into a positioning hole formed on the upper surface of the upper frame, and therefore the upper surface of the upper frame. Has to be perforated, and rainwater will infiltrate from here, and it will have to be poorly weathered, and the latter is assembled by sandwiching the upper and lower frames between the left and right vertical frames. However, on the contrary, in the case where the left and right vertical frames are sandwiched between the upper and lower frames, the outer side of the vertical frame cannot be used, and therefore, the lateral deviation prevention means needs to be separately provided.

[Means for Solving the Problem] The present invention was conceived with the object of providing a structure for preventing lateral displacement of a panel body in a panel shutter that can eliminate these drawbacks in view of the above-mentioned circumstances. Then, the lower frame of the succeeding panel body contacts the upper frame of the preceding panel body that moves downward in advance, by connecting the plurality of panel bodies that are connected to the connecting chain in a vertical direction at predetermined intervals in a series. Therefore, in the panel shutter configured to sequentially perform the closing operation, a sliding contact surface that is recessed inward with respect to the outer surface of the upper frame is formed at the upper portion of the outer surface portion of the upper frame, and Corrective pieces are provided at both left and right end portions so as to project outward beyond the sliding contact surface, while a lower end of the outer side surface portion of the lower frame is provided with a brim piece that slidably contacts the sliding contact surface from the outside when the closing operation is performed. Extend and fix the collar piece The cutout guides are provided on both left and right ends of the lower end corresponding to the base, and the cutout guides are corrected by the correction piece when the succeeding panel body descends in a lateral displacement state with respect to the preceding panel body. It is characterized in that it is configured so as to prevent lateral displacement.

Further, according to the present invention, even in the panel body assembled by sandwiching the left and right vertical frames with the upper and lower frames freely arranged, the present invention can surely prevent lateral displacement between the upper and lower panel bodies.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a shutter curtain of a panel shutter installed in an opening of a building, and a panel body 2 constituting the shutter curtain 1 has guide rails 3 provided on both left and right sides of the opening. The guide roller 4 projecting from the left and right end portions of the panel body 2 and the both end portions of the panel body 2 are guided so that the panel roller 2 can move up and down. Further, a connecting chain 5 is attached in series on the support shaft 4a of the guide roller 4 at a predetermined interval, and the connecting chain 5 is inside a shutter case 6 exposed by a portion of the guide rail 3. Is meshed with the drive sprocket 7 arranged at.

Further, the shutter case 6 is internally provided with a storage rail 8 which is appropriately inclined such that one end side faces the winding side of the drive sprocket 7 and the other end side is lower than the one end portion. By the chain winding operation of the drive sprocket 7, the guide roller 4 of the panel body 2 that has moved up the guide rail 3 is carried around to the storage rail 8 side and transferred onto the storage rail 8. The panel body 2 thus successively transferred onto the storage rail 8 moves laterally while rolling to the other end side of the storage rail 8 due to the weight of the panel body 2, and then sequentially in the shutter case 6. It is designed to be stored in parallel with each other.

The panel body 2 includes an upper frame 9, a lower frame 10, and left and right vertical frames 1
1, a middle frame 12 and members such as a face plate 13 (a glass plate or a synthetic resin plate) interposed between these frames. The left and right vertical frames 11 are composed of upper and lower frames 9. Screws 9a, 10a, which are sandwiched between 10 and screwed from above and below, are screwed into a screw pocket 11a provided on the vertical frame 11 to be integrally assembled. Moreover, at the lower part of the inner and outer side surfaces of the lower frame 10, a flange piece 10b extending downward is provided.
And the contact piece 10c are respectively formed. On the other hand, in the upper part of the inner and outer side surfaces of the upper frame 9, the collar piece 10b is slidable from the outer side in a slidable contact surface 9b and the contact piece 10.
Receiving surfaces 9c are formed so as to contact with c from above and to receive the same. When the shutter curtain 1 is closed, the collar piece 10b slides on the sliding contact surface 9b, and the contact piece 10c is received by the receiving surface 9c. It is supposed to be fixed.

Further, the collar piece 10b is notched at the lower left and right ends, and a guide portion 10e is further formed in the notch 10d. On the other hand, at the left and right ends of the upper frame 9, the correction piece 1
5 is integrally screwed, but the correction piece 1
5, the end portion on the sliding contact surface 9b side projects outward and corresponds to the flange piece 10b. Then, when the shutter curtain 1 descends, as shown in FIG.
Is laterally displaced with respect to the preceding panel body 2, the notch guide portion 10e of the succeeding panel body 2 comes down while coming into contact with the projecting portion 15a of the correction piece 15 of the preceding panel body 2. Therefore, the succeeding panel body 2 is corrected to have a lateral displacement and has a closed posture of the century. In addition, the correction piece 15 is configured such that a portion contacting with the notch guide portion 10e is an inclined portion 15b so that smooth correction guide can be performed.

In the embodiment of the present invention constructed as described above, the opening can be opened and closed by vertically moving the shutter curtain 1, but when the opening is closed here, the adjacent panel body is closed. 2 is sequentially descended by a connecting chain 5 in a suspended state at a predetermined interval, and after the preceding panel body 2 first comes into contact with the floor side, the connecting chain 5 is bent and the following panel body is bent. 2 descends so as to overlap the preceding panel body 2 and the panel bodies 2 are successively overlapped in this manner, whereby the opening is closed.

In the closing operation of the shutter curtain 1 as described above, even if the succeeding panel body 2 descends with respect to the preceding panel body 2 in a laterally laterally offset state, the lateral lateral deviation is surely achieved in the embodiment of the present invention. Will be corrected. That is, when the succeeding panel body 2 is laterally displaced laterally, the succeeding panel body 2 is provided with the notch guide portion 1 on the side of the succeeding panel body 2.
0e and the correction piece 15 on the side of the preceding panel 2 are lowered while receiving the above-described lateral deviation correcting action.
Therefore, the succeeding panel body 2 descends in a state in which the lateral displacement is surely corrected and overlaps with the preceding panel body 2 while maintaining the regular closed posture.

Therefore, in the embodiment of the present invention, the shutter curtain 1 is assembled even if the panel body 2 is assembled by sandwiching the left and right vertical frames 11 between the upper and lower frames 9 and 10.
In the fully closed state, there is almost no lateral displacement between the panel bodies 2, and the vertical frame 11 and the middle frame 12 are linearly continuous to provide an excellent appearance. Further, it is possible to reliably prevent damage to the edge of the panel body 2 and the connecting chain 5 due to the lateral displacement. Moreover, the lateral shift prevention of the present invention has an extremely simple structure, and it is not necessary to form a positioning hole on the upper frame as in the conventional case, and it is possible to implement an excellent rain proof at low cost.

The present invention is not limited to the above embodiment,
As the panel body to be implemented, it is possible to implement a panel body having no vertical frame and having a face plate attached between the upper and lower frame, and in this case, there is also an advantage that the correction piece can also be used as a retaining member for the face plate.

[Effects] In summary, since the present invention is configured as described above, the closing operation of the panel shutter is performed even when the panel body is assembled by sandwiching the left and right vertical frames between the upper and lower frames. At this time, even if the succeeding panel body is laterally displaced from the preceding panel body in the left-right direction, the succeeding panel body has the correction guide action of the correction piece on the preceding panel body side of the notch guide portion on the lower frame side. By receiving it, the lateral displacement will be corrected, and it will definitely overlap in the regular closed position. Therefore, the vertical design of the vertical frame and the intermediate frame is not impaired, and it is possible to surely prevent damage due to lateral displacement of the panel body edge and the connecting chain, while allowing for excellent appearance.

Moreover, the lateral displacement correction function of the panel body is such that, with respect to the upper frame, a sliding contact surface that is recessed in the upper part of the outer side surface portion and a correction piece that protrudes outward from the sliding contact surface at both left and right ends of the upper frame. With respect to the lower frame, the lower frame is to be demonstrated by having a flange piece that comes into sliding contact with the sliding contact surface from the outside and notch guide portions formed at both left and right ends of the flange piece. It is not necessary to open a positioning hole on the upper frame as in the past, and as a result,
The rainwater will not enter the upper frame through the positioning hole and accumulate in the upper frame, resulting in poor rain control.
