[Industrial applications]

 The present invention relates to a box-shaped body having a panel structure. That is, the present invention relates to a box-shaped body having a panel structure, which has a box shape, for example, in which articles and the like are stored.

[0002]

[Prior art]

 A box-shaped body having such a panel structure is generally prepared by first preparing a panel consisting of a face plate and a core material for each surface, and then assembling each such panel in a box-like shape through a frame. Although it was molded by the above, the followings have been recently developed in order to improve the manufacturing cost, dimensional accuracy, bonding accuracy, watertightness, etc. That is, FIG. 3 is an overall perspective view of such a recently developed box-shaped body 1. This recently-developed box-shaped body 1 having a panel P structure has a continuous outer surface plate 2 and a surface plate 2. It was provided with the core material 3 on each surface adhered to the inside and the frame 4 arranged at the corners between the core materials 3, and was molded as follows. That is, first, with respect to the outer surface plate 2 which is prepared in a linear and flat state as a whole, the core material 3 of each surface, the inner surface plate 5, and the frame 4 are longitudinally arranged in a predetermined positional relationship. After gluing while sequentially positioning in the direction (see the imaginary line display in FIG. 3), the outer surface plate 2 is attached to each frame 4 between the inner core members 3 of the panel P which is continuously and integrally molded in this way. The box-shaped body 1 was formed by bending along the line (see the solid line in FIG. 3).

Incidentally, FIG. 4 shows a main part of a conventional example of such a box-shaped body 1, FIG. 1 (1) is a sectional view before bending, and (2) is a sectional view after bending. That is, such a box-shaped body 1 is conventionally bent by bending the above-described bending and forming by bonding the surface plate 2, the frame 4, the core material 3 and the inner surface plate 5 at the corners of the panel P. The condition was fixed and it was assembled in a box shape. That is, conventionally, as shown in FIG. 4 (1), after placing the adhesive A in the important places, it is bent as shown in FIG. 4 (2), and the corner surface plate 2 and the frame are bent. 4, the core material 3 was adhered.

[Problems to be solved by the device]

 By the way, in such a conventional example, the following problems have been pointed out. That is, it is necessary to keep the bent state of the panel P as it is until the adhesive A hardens even after the bending. As described above, the box-shaped body 1 having the panel P structure has conventionally been problematic in that it needs to maintain the bent state after the adhesive A is cured during the curing time. However, some problems were pointed out in terms of time and cost. Especially, in view of the fact that the above-mentioned bending and the holding thereof are generally performed manually, such a problem has become remarkable.

In view of the above situation, the present invention has been made to solve the problems of the above-mentioned conventional example, and the frame is divided into a pair of frame members, respectively. Then, by adopting the welded joint method of welding the frame members, and in claim 2, by adopting the latch joint method of connecting the frame members by the latch structure, both can be easily and easily performed. It is an object of the present invention to propose a box-shaped body having a panel structure that can be molded without requiring curing time.

[0006]

[Means for Solving the Problems]

 The technical means of the present invention for achieving this object are as follows. That is, the box-shaped body of this panel structure includes a continuous surface plate, a core material on each surface adhered to the inside of the surface plate, and a frame arranged at a corner between the core materials. The surface plate is bent along each of the frames to be assembled in a box shape. Further, in claim 1, each of the frames is composed of a pair of divided frame members, and the frame members are connected by welding. Further, in claim 2, each of the frames is composed of a pair of frame members divided into two parts, and the frame members are connected by a latch structure.

[0007]

[Action]

 Since the present invention comprises such means, it operates as follows. In this box-shaped body, the core material of each surface is bonded to the inside of a continuous face plate, and the frame is arranged at the corner. At the time of molding, first, a continuous integrally molded panel is prepared in which a core material on each surface is positioned and adhered to a flat surface plate through frame materials at both ends. Then, a continuous surface plate of such a panel is bent along the respective frame members between the core members to form an overall box shape. In this case, the pair of frame members are integrated with each other to form each frame, and are tightly coupled to each other by a welding connection method in claim 1 and a latch connection method in claim 2. . In this way, a box-shaped body having a panel structure assembled in a box-like shape can be easily and easily formed by welding or latching instead of bonding.

【Example】

 The present invention will be described in detail below based on the embodiments shown in the drawings. 1 and 2 show the essential parts of each embodiment of the present invention. FIG. 1 (1) is a sectional view before bending, and FIG. 2 (2) is a sectional view after bending.

First, the box-shaped body 1 having the panel P structure will be described with reference to FIG. 3 described above. This box-shaped body 1 is arranged on one continuous outer surface plate 2, a core material 3 on each surface adhered to the inside of the surface board 2, and a corner with a space between each core material 3. A frame 4 and an inner surface plate 5 bonded to the inside of each core member 3, respectively, and the surface plate 2 of the panel P, which is previously integrally molded with the frame 4 and the surface plate 5, is formed. (Refer to the phantom line display in FIG. 3) By bending along each frame 4, it is assembled in a box shape (see the solid line display in FIG. 3). A honeycomb core, foamed plastic or the like is used as the core material 3 on each side or upper and lower surfaces, and an aluminum alloy plate or the like is used as the surface plates 2 and 5, and the frame 4 is used. As the material, a light metal material such as an aluminum material extruded is used. It is of course possible to use a type in which only the outer surface plate 2 is used and the inner surface plate 5 is not used regardless of the illustrated example.

In the box-shaped body 1 having the panel P structure shown in FIG. 1, each frame 4 is composed of a pair of frame members 6 divided in two, and the frame members 6 are welded to each other. It is connected by M. To describe these in detail, first, the frame 4 at each corner is composed of a pair of frame members 6 which are divided into two parts. The frame member 6 thus divided into two parts is used for each core member 3. It is attached to the end in advance by adhesion or the like, and in the illustrated example, it is also attached to the end of the inner face plate 5 by adhesion or the like. Further, both frame members 6 have a rounded surface formed on the outer side, a mutually opposing surface is formed flat, and a weld M is formed between the inner end portions 7 which are continuous with the opposing surface and are bent. Are applied (see FIG. 1 (2)), and thus, the welds M are closely connected.

Next, in the box-shaped body 1 having the panel P structure shown in FIG. 2, each frame 4 is composed of a pair of frame members 6 divided into two parts, respectively, and a space between the frame members 6 is They are connected by a latch structure. Explaining these in detail, first, the frame 4 at each corner is made up of two parts divided into a pair of frame members 6 as in the case of FIG. 1 described above. The frame member 6 is attached to the end of each core member 3 in advance by adhesion or the like, and is also attached to the end of the inner surface plate 5 by adhesion or the like. Furthermore, both frame members 6 are formed with rounded surfaces on the outer side, flat surfaces facing each other, and latch portions 8 and 9 corresponding to the inner ends of the facing surfaces are provided. There is. In the illustrated latch structure, one latch portion 8 has a protruding hook shape, and the other latch portion 9 has a protruding shape that can be locked by such a latch portion 8. By locking the parts 8 and 9, both frame members 6 are tightly coupled. Of course, this latch structure is not limited to the one shown in the drawing, and various other uneven shapes can be adopted.

The present invention is configured as described above. Then it becomes as follows. That is, in the box-shaped body 1 having the panel P structure, the core material 3 of each surface is attached to the inside of the continuous surface plate 2, and the frame 4 is arranged at the corner. Then, in the molding, first, the core material 3 on each surface to which the inner surface plate 5 is adhered is adhered to the outer surface plate 2 in a continuous and generally linear and flat state, respectively. A continuous, integrally-molded panel P is prepared in which the frame member 6 adhered to both ends and a small space are positioned and adhered in a predetermined positional relationship (see (1) of FIG. 1 and FIG. 2). See (1) in Fig. 3 and the phantom line display in Fig. 3). Then, with respect to such a panel P, the surface plate 2 is pressed from the outside, and is bent along the rounded surfaces of the frame members 6 between the core members 3 on the inside to form an overall box shape. It At that time, the pair of frame members 6 which were each divided into two parts are joined together by their opposing surfaces to form each frame 4, and in the example of FIG. By welding M, and in the example of FIG. 2, respectively, the latch portions 8 and 9 are locked, so that they are closely coupled (see (2) of FIG. 1 and FIG. 2). (See Figure (2)).

As described above, by adopting the welding M coupling method or the latch coupling method, the bent state of the panel P is fixed without adhesion unlike the conventional example of this kind, and thus the box-like shape is formed as a whole. The box-shaped body 1 having the panel P structure assembled to is molded (see the solid line display in FIG. 3). As described above, the bent state of the box-shaped body 1 can be easily and easily fixed only by the welding M and the latching. That is, the box-shaped body 1 does not need to maintain the bent state of the panel P during the curing time of the adhesive A even after being bent, unlike the conventional example of this kind shown in FIG. Molding is performed with a reduced number of steps, especially in the example of FIG. Note that, even after the box-shaped body 1 is joined, the outside is joined by the continuous surface plate 2 and the inside is joined by the weld M or the latch, so that the shape is maintained.

In FIG. 3, reference numeral 10 is a joint between the panels P. FIG. 5 is a perspective view of the cart. That is, the box-shaped body 1 is used as a cart in which articles are stored and various services are provided by further adding a door D, casters C, a back plate, and the like.

[0015]

As described above, the box-shaped body having the panel structure according to the present invention is formed by dividing the frame into two pairs of frame members, respectively. The following effects can be obtained by adopting a welded joint method of welding the above-mentioned materials and, in claim 2, by adopting a latched joint method of connecting the frame materials by a latch structure.

That is, the box-shaped body having this panel structure is very easy and easy to assemble and form. In other words, unlike the conventional example of this kind, it is not necessary to keep the bent state even after bending during the curing time of the adhesive, which saves time and labor and saves time and cost. Excellently shaped. Thus, the effects of the present invention are remarkably large, such as the problems existing in this type of conventional example are eliminated.
