Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a panel body structure used for a panel shutter or the like.

[Problems to be Solved by Conventional Techniques and Inventions] Conventionally, a panel body such as a panel shutter of this type is formed by welding a surface material formed by bending a thin plate material such as a steel plate or a stainless plate with a bender or the like. In general, they were formed by joining.

However, the panel body formed in this manner cannot be limited in length, thickness, etc. depending on the capability of the bender, and has a disadvantage that the number of steps increases and the cost increases. .

Therefore, it is conceivable to form the panel body by extrusion molding (aluminum or the like) having almost no restriction on the length dimension. Because it is necessary to increase the wall thickness, there is a disadvantage that the panel weight becomes heavy,
There is a disadvantage that the material cost increases.

In order to improve this, it is proposed to form the panel body by combining a plurality of extruded materials. However, in the case where the panel body is used to connect adjacent ones in a series, connecting portions for connecting the adjacent panel bodies are required on both side edges thereof. It is necessary to form a dedicated part for forming the connecting part, and there is another problem that a mold for that purpose is required, the number of parts is large, and the cost is high.

[Means for Solving the Problems] The present invention has been made in view of the above-mentioned circumstances, and has been created with the object of providing a panel body structure capable of eliminating these disadvantages. In forming a plurality of panel bodies in which adjacent panel bodies are connected in series, a pair of panel pieces are integrally assembled to form a panel body.
The pair of panel pieces are formed by cutting the same extruded material into a predetermined size, and have one symmetrical shape on one side which is a face facing each other by reversing the direction of the panel body connecting direction of one panel piece. A fitting portion that can be integrally fitted is formed, and the other side surface, which is a surface facing the adjacent panel body when the one panel piece is turned over, is symmetrical to each other, and A connecting portion for connecting with another side surface is formed.

The second invention is a panel body formed by integrally assembling a pair of panel pieces, wherein the pair of panel pieces is formed by cutting the same extruded material to a predetermined size, and On one side surface of one of the panel pieces, which is a surface facing each other when inverted in the panel body connecting direction, a fitting portion that is symmetrical with each other and can be integrally fitted is formed, and the one panel piece is On the other side, which is a surface facing the adjacent panel body by reversing the above, a connecting portion for forming a connection between the other side surface of the adjacent panel body and being symmetrical with each other is formed. On the side surface, a protruding piece that makes one panel surface continuous with the panel surface of the mating panel piece and a restricting piece that restricts deformation of the protruding piece formed on the mating panel piece to the outside of the panel surface are integrally formed. Is characterized by being Than it is.

According to the present invention, a lightweight panel body can be formed by this structure without increasing the thickness in extrusion molding.

Next, an embodiment of the present invention will be described with reference to the drawings.
In the drawings, reference numeral 1 denotes a panel body.
Is formed to be long in the left-right direction, and a plurality of sheets are connected in a series through a connecting member such as a chain to form a shutter curtain of a panel shutter. is there.

Numeral 2 is a panel piece formed into a hollow shape by aluminum extrusion, and the panel piece 2 is formed integrally with the panel piece 2 having the same shape to form the panel body 1. But one panel piece 2
On one side surface 2a which is a surface facing each other by reversing the panel body connecting direction, a fitting portion which is symmetrical with the same side surface 2a of the reversed same panel piece 2 and can be integrally fitted with each other is provided. Is formed. That is, on one side surface 2a of the panel piece 2, a first protruding piece 2d for making one panel surface 2b flush with the other panel surface 2c of the mating panel piece 2 in a plane.
And a second protruding piece 2e along the inner surface of the first protruding piece 2d of the mating panel piece 2 in the fitted state, and the opposing surfaces of the protruding pieces 2d and 2e in the fitted state are mutually Engagement projections 2f and 2g to be engaged are formed, respectively.

Reference numeral 2h denotes a locking piece protruding from one side surface 2a to restrict the second protruding piece 2e from escaping inward, that is, in the direction of disengaging.

Furthermore, the other side surface 2s which is a surface facing the panel body 1 adjacent to each other by the reversal of the one panel piece 2 is:
Like the one side surface 2a, it is not a straight line but a concave groove, but a connecting protrusion 2m is protruded from an edge on the side where the second protrusion 2e is formed, and the first protrusion is On the edge on the side where 2d is formed, there is formed a connecting step 2n into which the connecting protruding piece 2m of the adjacent panel body 1 which is symmetrical to each other by turning over the panel piece 2 enters and which opposes.

On the other hand, reference numeral 3 denotes a fixing bracket formed in a U-shape. The fixing bracket 3 is screwed to the left and right side surfaces of the panel piece 2 fitted to each other to form an integrated panel body 1. The connecting member such as the chain described above is attached to the fixing bracket 3.

In the embodiment of the present invention configured as described above, the panel body 1 is formed by cutting a single extruded material to a predetermined size to form a panel piece 2 having the same shape, and inverting the panel pieces 2 having the same shape. It is formed by integrally assembling in a shape and then fixing the fixing bracket 3 with screws.

As described above, in the case where the present invention is implemented, the panel body 1 is formed to be long in the left-right direction, but the panel body 1 is formed by extrusion molding with almost no restriction on the length dimension. It is formed by fitting and assembling a panel piece 2 having an inverted shape integrally. In other words, the width dimension during extrusion is substantially half of the panel width, so that it is not necessary to technically increase the thickness of the extruded material, and accordingly, the weight of the panel can be reduced, or the material cost can be reduced. Can be reduced.

Moreover, the panel body 1 has a first step of cutting the extruded material and a second step of forming screw holes in the panel piece 2 formed in the first step (by simultaneously forming the screw holes during extrusion molding). (Can be omitted)) and a third step of fitting and assembling the panel piece 2 and a fourth step of screwing the fixing fitting 3, so that the number of steps can be reduced and the cost can be reduced.

In this case, the panel body 1 is turned by turning one of the panel pieces 2 in the direction in which the panel bodies 1 are connected, and in this case, the two side faces 2a that are symmetrical to each other are fitted together. On the other side surface 2s of the panel body 1 assembled in this manner, a connection protruding piece 2m for connecting the adjacent panel body 1 with the adjacent panel body 1 by being inverted and also symmetrical, As a result of the formation of the connecting step 2n, the panel body 1 is assembled using a pair of panel pieces 2 cut with the same extruded material, but is adjacent to the assembled panel body 1. It is not necessary to separately provide an end member for connecting adjacent panel bodies to a side surface connected to each of the panel bodies 1, so that the number of parts can be reduced and assembly of the panel body 1 is simplified, Is it possible to reduce the panel weight? Fee cost is also reduced.

Further, since the panel body 1 is formed by assembling a pair of the same panel piece 2 and the fixing bracket 3 by a simple operation, it is possible to reduce the number of parts and simplify the structure, or to reduce manufacturing errors. be able to.

Further, since the panel pieces 2 of the same shape formed by extrusion molding are integrally fitted and assembled in an inverted manner, the warpage of the panel pieces 2 generated at the time of extrusion molding is canceled out to form the panel body 1. There is an advantage that dimensional accuracy can be improved.

Note that the present invention is not limited to the above-described embodiment, and it goes without saying that, for example, the panel body structure of the present invention can be implemented in a structure other than the panel shutter. Also, the shape of the fitting portion formed on one side surface 2a of the panel piece 2 is not limited to the above-described embodiment, and may be, for example, as shown in FIGS. 4A, 4B, 4C, and 4D. To
A restricting piece 2k may be provided for restricting deformation of the protruding piece 2j (or protruding piece 2d) that connects the panel surface 2b to the panel surface 2c of the mating panel piece 2 to the outside of the panel surface. That is, in the first embodiment, the first protrusion 2d may be pressed by the second protrusion 2e due to a molding error or an assembly error, and may be deformed outward from the panel surface. In the other example described above, by restricting this deformation, it is possible to prevent the inconvenience that the projecting piece 2j (or the projecting piece 2d) forms a step on the panel surface.

[Effects] In summary, since the present invention is configured as described above, it is intended to form a panel body whose length can be freely set by extrusion molding. It consists of a pair of panel pieces, and the pair of panel pieces may be the same extruded material cut to a predetermined size, and the panel body is turned one panel piece in the panel body connecting direction, In that case, it is assembled by fitting the fitting portions of one side facing each other in a symmetrical manner, and the other side of the panel body assembled in this manner is also inverted by the above-mentioned inversion. A connecting portion for forming a connection between adjacent panels is formed symmetrically. As a result, while the panel body is assembled using a pair of panel pieces cut out of the same extruded material, the panel body is adjacent to the side surfaces respectively connected to the adjacent panel bodies of the assembled panel body. Since it is not necessary to separately provide an end member for connecting the panel bodies, the number of parts can be reduced, the assembly of the panel body can be simplified, and the weight of the panel can be reduced, or the material cost can be reduced.

Furthermore, since the panel body is formed by fitting and assembling one of the pair of panel pieces obtained by cutting the same extruded material, the warpage of the extruded material generated during the extrusion can be offset. Thus, the dimensional accuracy of the panel body is improved.

Also, on one side formed with the fitting portion, a protruding piece for connecting one panel surface to the panel surface of the mating panel piece,
If the protruding piece formed on the mating panel piece is integrally formed with a restricting piece that restricts the deformation of the protruding piece to the outside of the panel surface, a step is formed on the panel surface due to the deformation of the protruding piece due to molding error or assembly error. The trouble that occurs can be prevented.
