[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame structure constituting a panel of a panel shutter.

[0002]

2. Description of the Related Art As is well known, a panel shutter is formed by connecting a plurality of relatively large panels, and cannot be wound and stored in a storage case. Is done. Therefore, although depending on the type of the panel shutter, the connection form between the panels is generally poor, and the panel bends due to wind pressure or the like that acts when the panel is closed, and the bending causes three-dimensional deformation. Due to this deformation, a gap is created between the panels that are always in close contact, and if the gap is enlarged further, the gap between the panels will shift, and if the deformation exceeds the elastic range, the original It is not possible to return to the panel shape, and the shutter cannot be stored.

[0003] If each panel has a shutter structure that is flexibly connected via a hinge joint, the strength of the entire shutter is greatly improved by the interaction between the panels, and of course, the deformation of the panel itself can be suppressed. However, if the panel shutter does not have a fixed joint and has a structure in which each panel is separated at the time of storage, the above problem occurs due to the action of an external force. In particular, as the length of the panel increases, the above-described phenomenon becomes more significant due to the influence of bending and torsion due to the weight of the panel.

A panel shutter device filed by the applicant on June 18, 1988 (Japanese Utility Model Application Laid-Open No. Hei 2-2492).
The upper panel has a convex curved surface, the lower panel has a concave curved surface, and the two panel surfaces are in close contact with each other. I have. The contact pieces protrude to the outside and the inside, but the joining surfaces of the upper and lower panels are merely in contact with each other, and the joined state is released and separated when stored. Accordingly, if the panel is deformed by the action of an external force, the joint surface is separated and a gap is formed between the panels, and sometimes the panel itself is plastically deformed.

In the "frame structure of panel shutter" according to Japanese Utility Model Laid-Open No. 1-96990, projecting pieces are provided on upper and lower frames, and an engagement receiving portion of the lower frame is engaged with an engaging portion formed on the upper frame. Panel to prevent displacement. However, even in such a structure, the joint surfaces of the upper and lower panels are merely in contact with each other, as in the conventional example, and are not structures that can prevent deformation due to external force.

[0006]

As described above, there is a problem as described above in the joint surface structure of each panel constituting the panel shutter. The problem to be solved by the present invention is these problems. Even if external force acts, the deformation is small,
Provided is a panel frame structure that does not generate a gap between panels.

[0007]

SUMMARY OF THE INVENTION The panel frame structure of the present invention has the following features. That is, the guide rail for guiding the panel is extended into the storage case, and the panel raised with the opening of the frontage is configured to be swung and suspended, and the joint surface of the panel lower frame has a predetermined arc. It forms a convex curved surface, and the joint surface of the panel upper frame forms a concave curved surface having the same arc. In the present invention, a protruding piece is extended on one side of the lower frame, and a locking piece is provided on the other side. On the other hand, a locking receiving portion for locking with the locking piece is provided on an upper frame of the lower panel. Form each.

[0008]

The projecting piece formed on the lower frame of the upper panel is constructed by configuring the joint structure of the upper and lower panels as described above.
When the shutter is closed, it contacts the side of the upper frame of the lower panel. In addition, the locking piece is locked with the locking receiving portion. In this state, even if an external force (wind pressure) acts on the side surface, the projecting piece hits the side surface of the upper frame, and the locking piece and the locking receiving portion are separated. Is prevented, the degree of deformation of the panel is suppressed, and, of course, displacement is prevented. Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 6 is a specific example showing a panel shutter to which the present invention is applied. The figure shows a state in which the shutter is closed, and the panels 1a and 1b constituting the shutter are shown.
Are connected to each other, and the shutter opens and closes along guide rails 2, 2 provided on both sides of the frontage. The guide rail 2 has an inverted U shape in the storage case 3 above the frontage, and has a curved rail portion 4, a horizontal rail portion 5, an inclined rail portion 6, and a hanging rail portion 7. A main traveling tool is pivotally supported below both side ends of the panel 1, and an auxiliary traveling tool is pivotally supported at an upper portion thereof. It is loosely fitted to the formed joint and panel rail. The panels 1a, 1b,... Are connected to each other when the auxiliary traveling tool is loosely fitted to the joint portion, and the shutter is opened and closed when the main traveling tool moves on the guide rail 2. The details are described in Japanese Utility Model Laid-Open No. 2-2492.

FIG. 7 shows the state of each panel 1 with the shutter opened.
a, 1b... are stored in the storage case 3. In this way, the panels 1a, 1b... rise along the guide rails 2 and the curved rail portions 4, formed in the storage case 3, The horizontal rail 5, the inclined rail 6, and the hanging rail 7 pivot and suspend. In this case, the main traveling tool moves while being guided by the guide rail 2, while the sub traveling tool moves from the joint portion to the panel rail.

FIG. 1 is a sectional view showing a panel frame structure according to the present invention. The panel 1 is constructed by inserting a plate material 10 into a frame framed by an upper frame 8, a lower frame 9 and left and right frames. The upper and lower frames 8, 9 are extruded members having a predetermined cross section shown in FIG. Therefore, the lower frame 9 has a joint surface 11 which forms a smooth convex curved surface, a protruding piece 13 extends downward on the outer side 12, and forms a concave portion 15 on the inner side 14. A locking piece 16 is provided on the extension of the joining surface 11. on the other hand,
The upper frame 8 has a concave joint surface 17 that can fit into the joint surface 11 of the lower frame 9.
The lock receiving portion 18 bent into a mold is erected. Therefore, the tip of the projecting piece 13 abuts on the outer surface of the upper frame 8 of the lower panel 1, and the locking receiving portion 18 is locked to the locking piece 16.

FIG. 2 shows a case where the wind pressure P acts on the shutter. Since the main traveling tool is restrained by the guide rails 2 and 2 on both sides, the center portion is curved inward as shown in FIG. It is the frame structure of the present invention that suppresses this bending deformation even a little, and FIG. 3 shows an enlarged view of a portion A in FIG. If the upper and lower panels 1 and 1 are inclined as shown in the figure, the tip of the projecting piece 13 of the lower frame 9 comes into contact with the outer surface of the upper frame 8, and the above-mentioned tip functions as a kind of fulcrum.
Then, a slight gap is created between the joining surfaces 11 and 17,
The locking piece 16 is locked to the locking receiving portion 18 of the upper frame 8 to prevent the panels 1 and 1 from tilting. Therefore, both joining surfaces 11,
The gap between the 17 is not enlarged any more, and it is even more separated so that no displacement occurs.

FIG. 4 shows another embodiment of the present invention.
A projecting piece 13 and a locking piece 16 are formed on the lower frame 9, and a locking receiving portion 18 is formed on the upper frame 8, respectively. The basic structure is the same as that of the above embodiment. FIG. 5 shows the upper frame 8 of the lower panel 1

A roller 19 is supported on the shaft 1. The outer peripheral surface of the roller 19 has a size slightly protruding from the joining surface 17. Therefore, when the panel 1 is stored in the storage case 3, the panel 1 approaching the curved rail portion 4 is inclined, but the sliding of the joint surfaces 11 and 17 caused by the inclination is smoothly performed.

That is, the joining surface 11 of the upper panel 1 can move while rolling the roller 19.
Further, a sliding member (not shown) is disposed in the recess 15 of the lower frame 9 at a position where the roller 19 is attached, and a smooth convex curved surface continuing from the inner surface to the joining surface 11 is formed. . As described above, in the panel frame structure of the present invention, the joining surface of the lower frame forms a convex curved surface, and a protruding piece extends downward on one side,
A locking piece is provided on the other side, while the joining surface of the upper frame forms a concave curved surface to form a locking receiving portion for locking to the locking piece, and the following effects are obtained. Can be.

[0015]

[Effect of the Invention] Since the upper and lower frames of the present invention are formed with a protruding piece, a locking piece, and a locking receiving portion, deformation of the panel due to external force such as wind pressure is suppressed, and as a result, there is generated between both joint surfaces. The expansion of the gap can be prevented, the displacement of the panel can be prevented, and the airtightness and watertightness of the shutter can be improved. In addition, by configuring the upper and lower frames of the panel in this way, even a panel having a large width can withstand external force, and the thickness of the panel itself can be reduced. Further, the opening and closing operation of the panel is facilitated.
