Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a frame structure that constitutes a panel of a panel shutter.

[0002]

[Prior Art]

 As is well known, the panel shutter is configured by connecting a plurality of relatively large panels, and cannot be rolled up and stored in a storage case, but is stacked and stored in the thickness direction. Therefore, although it depends on the model of the panel shutter, the connection between the panels is generally poor, and the panel bends due to the wind pressure that acts when it is closed, and the deflection can cause three-dimensional deformation. .. As a result of this deformation, a gap is created between the panels that are always in close contact with each other. If the gap becomes larger and the gap becomes larger, the panels will be displaced, and if the deformation exceeds the elastic range, It will not be possible to return to the panel shape of, and the storage of the shutter will be impossible.

If each panel has a shutter structure in which it can be bent 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 is suppressed. However, if the panel shutter has a fixed joint and the panels are separated when stored, the above problem will occur due to the action of external force. In particular, as the length of the panel increases, the phenomenon described above becomes remarkable due to the influence of bending and twisting due to the weight of the panel.

Although the panel joint surface of the “panel shutter device” (Actual No. 2-2494) submitted by the applicant on June 18, 1988 depends on its own storage form, the lower end surface of the upper panel is It has a convex curved surface, the upper end surface of the lower panel has a concave curved surface, and both joint surfaces are in close contact. And, although the contact pieces project to the outside and the inside, the joint surfaces of the upper and lower panels are merely in contact with each other, and the joint state is released and separated during storage. Therefore, if it 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.

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

[0006]

[Problems to be solved by the present invention]

 As described above, the joint surface structure of each panel forming the panel shutter has the above-mentioned problems. The problems to be solved by the present invention are these problems, and provide a panel frame structure in which deformation is small even when an external force is applied and no gap is formed between the panels.

[0007]

[Means for Solving the Problems]

 The panel frame structure of the present invention has the following features. In other words, a guide rail for guiding the panel is extended into the storage case, and the panel that rises with the opening of the front is swung to be suspended, and the joint surface of the panel lower frame has a predetermined arc. It has a convex curved surface, and the joint surface of the upper frame of the panel is a concave curved surface having the same arc. Further, in the present invention, a projecting piece is extended on one side of the lower frame, and a locking piece is provided on the other side, while a locking receiving portion for locking the locking piece is provided on the upper frame of the lower panel. Are formed respectively.

[0008]

[Action]

 By constructing the joint structure of the upper and lower panels as described above, the protruding piece formed on the lower frame of the upper panel contacts the upper frame side surface of the lower panel when the shutter is closed. Further, the lock receiving portion is locked to the lock piece, and even if an external force (wind pressure) acts on the side surface in this state, the projecting piece contacts the side surface of the upper frame and separates the lock piece from the lock receiving portion. Therefore, the degree of deformation of the panel is suppressed and, of course, the positional deviation is prevented. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

【Example】

 FIG. 6 is a specific example showing a panel shutter to which the present invention is applied. Although the figure shows a state in which the shutter is closed, the panels 1a, 1b ... Constituting the shutter are connected to each other, and the shutter is opened and closed along the guide rails 2 and 2 provided on both sides of the frontage. The guide rail 2 has an inverted U shape inside the storage case 3 at the upper part of 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 above the panel. The main traveling tool is loosely fitted on the guide rail 2, and the auxiliary traveling tool is extended from the lower end of the panel to the upper portion. It is loosely fitted to the joint portion and the panel rail that are formed. The panels 1a, 1b, ... Are connected to each other by loosely fitting the sub-running tool into the joint portion, and the shutter is opened and closed by moving the main running tool on the guide rail 2. Details are described in Japanese Utility Model Laid-Open No. 2-2492.

FIG. 7 shows a process in which the shutters are opened and the panels 1a, 1b ... Are stored in the storage case 3, and thus the panels 1a, 1b ... Ascend along the guide rails 2. The curved rail portion 4, the horizontal rail portion 5, the inclined rail portion 6, and the hanging rail portion 7 formed inside the storage case 3 are pivoted and suspended. In this case, the main running tool moves while being guided by the guide rails 2, while the sub running tool moves from the joint to the panel rail.

FIG. 1 is a cross-sectional view showing the panel frame structure of the present invention. The panel 1 is constructed by inserting a plate material 10 into a frame body framed by an upper frame 8, a lower frame 9 and left and right frames, The upper and lower frames 8 and 9 are extruded materials having a predetermined cross section shown in FIG. Therefore, the joint surface 11 of the lower frame 9 forms a smooth convex curved surface, the protruding piece 13 extends downward on the outer side 12, and the concave portion 15 is formed on the inner side 14, and the lower end of the concave portion 15 is formed. A locking piece 16 is provided on the extension of the joint surface 11. On the other hand, the upper frame 8 has a concave joint surface 17 that can be adapted to the joint surface 11 of the lower frame 9, and an L-shaped bent lock receiving portion 18 is erected on the inner side 14 of the joint surface 17. There is. Therefore, the tip of the protruding piece 13 contacts 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 the case where the wind pressure P acts on the shutter. Since the main traveling tool is constrained by the guide rails 2 and 2 on both sides, the central portion is curved inward 14 as shown in FIG. The frame structure of the present invention suppresses this bending deformation as much as possible, and FIG. 3 shows an enlarged view of the portion A of FIG. If the upper and lower panels 1, 1 are inclined as shown in the figure, the tip of the protruding piece 13 of the lower frame 9 contacts the outer surface of the upper frame 8 so that the above-mentioned tip functions as a kind of fulcrum. Become. Then, a slight gap is formed between the joint surfaces 11 and 17, and 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, the above-mentioned gap between the two joint surfaces 11 and 17 does not expand any further, and much less the positional deviation occurs due to separation.

FIG. 4 shows another embodiment of the present invention in which a lower frame 9 is formed with a projecting piece 13 and a locking piece 16 and an upper frame 8 is formed with a lock receiving portion 18. The basic structure is the same as that of the above embodiment. FIG. 5 shows a case where a roller 19 is axially supported in a notch portion of the upper frame 8 of the lower panel 1. The roller 19 fixes a shaft 21 in a hollow portion 20 of the upper frame 8 and the roller 19 is attached to the shaft 21. It is pivotally supported. The outer peripheral surface of the roller 19 has a size slightly protruding from the joint surface 17. Therefore, when the panel 1 is stored in the storage case 3, the panel 1 that has reached 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 joint surface 11 of the upper panel 1 can move while rolling the roller 19. In addition, a sliding member (not shown) is arranged in the concave portion 15 of the lower frame 9 at a position where the roller 19 is attached to form a smooth convex curved surface continuous to the joint surface 11 and continuing to the inner side surface. .. As described above, in the panel frame structure of the present invention, the joint surface of the lower frame has a convex curved surface, the protruding piece extends downward on one side surface, and the locking piece is provided on the other side surface. The joining surface of the upper frame has a concave curved surface to form a lock receiving portion for locking the lock piece, and the following effects can be obtained.

[0015]

[Effect of the device]

 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 against external force such as wind pressure is suppressed, and as a result, expansion of the gap between both joint surfaces is prevented. However, the position shift of the panel can be prevented, and the airtightness and watertightness of the shutter are improved. Further, by constructing the upper and lower frames of the panel in this manner, even a horizontally long panel can withstand external force, and the thickness of the panel itself can be reduced. As a result, the opening / closing operation of the panel is facilitated.
