[Detailed Description of the Invention] (Industrial field of application) The present invention is mainly used in the field of folding box pallets or containers, and forklifts and suspension devices with luggage stored inside. Foldable box for stacking up and down in multiple stages using, or placing on a shelf in a three-dimensional warehouse for storage or transportation,
In detail, aiming at weight reduction and cost reduction, a large number of linear bodies are arranged horizontally and vertically and fixed to form a mesh or lattice wall body, and the mesh box can be folded by this mesh wall body. It relates to a folding mesh box which is designed to be formed.

(Prior Art) First, a schematic structure of a folding mesh box will be described with reference to FIG. 1. The mesh wall A forms a bottom wall 1 and front, rear, left and right side walls 2 to 5 standing upright around the bottom wall 1. Of these, the front and rear side walls 2, 4 are connected to the front and rear peripheral edges of the bottom wall 1 by spiral coils 6, 7, and the left and right side walls 3, 5 are connected to the rear side wall 4 by spiral coils 8, 9 and still The side wall 2 is vertically divided into two, and the divided wall bodies 2A and 2B are also connected by the spiral coil 10.

Lock bars 11 capable of laterally moving a certain distance are attached to the left and right ends of the front side wall 2 by mounting metal fittings 12, and U-shaped locks are attached to the left and right side walls 3 and 5 adjacent to the front side wall 2. The metal fittings 12 and 13 are fixed, and the side walls 2 to 5 are maintained in an upright state as shown by locking the lock rod 11 by fitting the lock bar 11 into the lock metal fitting 13. Also, by releasing the locked state, the left and right side walls are locked. 3,5 can be folded around the spiral coils 8,9 toward the rear side wall 4 as shown by the arrow, and the front and rear side walls 2,4 are spiral coils 6,7.
It can be folded toward the bottom wall 1 around. Legs 17 are fixed to the four corners of the bottom wall 1 so that the forks of a forklift can be inserted into the space on the back surface of the bottom wall 1.

5 (a) to 5 (c) show details of the mesh wall body A and the lock rods 11 and the fittings 12 mounted on the mesh wall body A. The mesh wall body A is composed of a large number of vertical metal linear bodies. a and the metal linear body b in the horizontal direction are overlapped so that the vertical linear body a is located outside and the horizontal linear body b is located inside, and the intersections of the two are fixed by welding to form a mesh or grid. It is formed into a shape.

The lock rod is attached to the mesh wall body A forming the front side wall 2.
The mounting bracket 12 for mounting 11 is fixed, and the mounting bracket
12, lateral piece 12a extending laterally, as shown in FIGS. 5b and 5c
And both side vertical pieces 12c extending in the vertical direction from both ends of the horizontal piece 12a and having a convex curved portion 12b for inserting the lock rod 11 in the middle are integrally formed by a linear body. , The horizontal piece 12a of the fitting 12 is applied to the outer vertical linear body a of the mesh wall body A, and welded at the intersection 14 thereof, and the both vertical vertical pieces 12c, 12c are joined to the inner horizontal linear body b. Applied,
It is welded at the intersection 15 thereof, whereby the lock rod 11 is surrounded by the convex curved portions 12b of the vertical side pieces 12c, 12c and the vertical linear body a,
The lever 16 fixed to the lock bar 11 is the vertical piece 12 on the left side in the figure.
It is movably supported in the lateral direction while being supported by the distance between the c and the vertical part 12c on the right side. The tip 16 of the lever 16
As shown in Fig. 5c, a is fixed so as to be orthogonal to the lock rod 11 and further slightly protrudes, and is normally hung along the wall due to the weight of the lever 16. In this state, the tip of the lever is 16a is engaged with the vertical linear body a to prevent the lock rod 11 from moving unexpectedly laterally, and the lever 16 is rotated about the lock rod 11 to the position indicated by the chain line in the figure. The lock rod 11 can be freely laterally moved for the above-mentioned fixed distance.

(Problems to be Solved by the Invention) With the above-mentioned conventional structure, there is a problem in the fixing structure of the mounting fitting. That is, when the fitting 12 is fixed to the mesh wall A, the lateral piece 12a of the fitting 12 is abutted and fixed to the outer vertical linear body a of the wall A, while the vertical 12a is fixed. Since the piece 12c is adapted to be attached to and fixed to the inner lateral linear body b, when the wire diameter of the linear body forming the mesh wall body A, particularly the outer vertical linear body a is changed, As shown in FIG. 6a, the fitting 12 is inclined inward and the hole for inserting the lock rod 11 is inserted.
When the diameter of 11a changes and the tip 12d of the vertical piece 12c protrudes inward, and the width of the mesh of the mesh wall body A, especially the width between the vertical linear bodies a and a changes. To the mounting bracket 1
The second vertical piece 12c is disengaged from the inner horizontal linear body b, is applied to the outer vertical linear body a as shown in FIG. 6b, and has to be fixed at this position. As shown in the figure, the lock rod insertion hole 11a is enlarged more than necessary, and the vertical piece 12c is lifted from the vertical linear body a and cannot be firmly fixed.

Therefore, with the conventional mounting member 12, if the wire diameter or the mesh width of the linear body forming the mesh wall body A changes, it is necessary to manufacture a mounting member having a size corresponding to the wire diameter and the mesh width, which is inferior in compatibility. was there.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention arranges the longitudinal linear members on the outer side and the horizontal linear members on the inner side, and arranges them in a mesh shape. While firmly fixed to form a mesh wall body, these mesh wall bodies are arranged to face each other, and at the same time one of the adjacent mesh wall bodies is mounted with a lock rod that can move laterally by a certain distance by a mounting metal fitting, In a foldable box in which a U-shaped lock metal fitting is fixed to the other side, and adjacent mesh wall bodies are locked to each other by fitting a lock rod into the metal fitting to assemble into a mesh box, the mounting metal fitting is: An upper horizontal piece extending in the horizontal direction, both vertical pieces extending in the vertical direction from both ends of the horizontal piece and having a convex curved portion through which the lock bar is inserted, and further in the horizontal direction from the lower ends of both vertical pieces. The lower horizontal part that extends is integrated by a linear body The upper and lower lateral portions of the mounting metal fitting are formed so as to be pressed against and fixed to the outer vertical linear members of the mesh wall body.

(Operation) Since the upper lateral piece of the mounting bracket is attached and fixed to the outer vertical linear body of the mesh wall body, the lower horizontal portion is also fixed to the outer vertical linear body and fixed to the mesh wall. Even if the wire diameter of the linear body forming the body, particularly the vertical linear body, changes, the mounting metal fitting is fixed to the surface along the mesh wall body, and the fixing position is not displaced inward.

Also, since the upper and lower lateral pieces of the mounting bracket naturally extend in the lateral direction, even if the mesh width of the mesh wall body, especially the width between the vertical linear bodies, changes, As long as the distance between adjacent vertical linear members is narrower than the length of one piece, these vertical linear members can be freely abutted and fixed, and the fixed position is not displaced.

(Embodiment) As shown in FIGS. 1 and 2, the mounting metal fitting 18 includes an upper lateral piece 18a extending in the lateral direction and a longitudinal direction extending from both ends of the lateral piece, with a convex curve in the middle. The vertical side members 18c, 18c, which are deformed, and therefore the opposite side thereof has the convex curved portion 18b serving as the lock rod insertion recess 19, further extend in the lateral direction from the lower ends of the vertical members 18c, 18c, and the upper horizontal member 18a. It is a substantially rectangular ring-shaped member composed of the lower horizontal piece 18d facing each other, and is integrally formed of a metal linear body. When forming a rectangular annular endless shape by bending a metal linear body, the abutting end faces of the linear body may be welded and integrated, or the abutting end face may be on the side of the upper lateral piece 18a.

On the other hand, a substantially U-shaped lever 21 is fixed to the lock rod 20 in the same manner as in the conventional case. The lock rod 20 is fitted into the lock rod insertion recess 19 of the mounting member 18, and in this state, the upper and lower parts of the mounting member 18 are attached. The horizontal piece 18a, 18d is applied to the outer vertical linear body a of the mesh wall body A composed of the outer vertical linear body a and the inner horizontal linear body b, and the respective intersections 22, 22 are welded. Stick to it. The lock rod 20 is supported by a lock rod insertion hole 23 formed by the concave portion 19 and the vertical linear body a, and the lever 21 is provided with both vertical portion pieces 18.
Lateral movement is possible within the range of contact with c and 18c.

As is apparent from the state shown in the drawing, both the upper and lower lateral pieces 18a, 18d of the fitting 18 are applied to the outer vertical linear bodies a, a of the mesh wall body A and fixed at that position. Regardless of the wire diameter of the vertical linear body, particularly the outer vertical linear body a, the vertical linear body can always be fixed in a fixed position at a fixed position. Further, since the upper and lower lateral pieces 18a and 18d of the mounting member 18 naturally extend in the lateral direction, regardless of the mesh width of the mesh wall body A, in particular, the distance between adjacent vertical linear bodies a and a. , Upper and lower horizontal pieces 18a, 18d
Is attached to and fixed to the vertical linear bodies a, a.

FIG. 3 shows another embodiment of the present invention. In the above embodiment, the mounting member 18 is formed in a rectangular annular endless shape. The horizontal piece 18d or the upper horizontal piece 18a may extend halfway in the horizontal direction.

(Effect) According to the present invention, even if the wire diameter or the mesh width of the horizontal and vertical linear members of the mesh wall forming the folding box changes, the mounting bracket is always fixed in a fixed position at a fixed position. It has sufficient compatibility with mesh wall bodies having different wire diameters and mesh widths, and is extremely effective for mass production.
