Description

[Detailed description of the invention] The present invention relates to a net basket pallet constructed so that it can be folded into a flat state when not in use, and which achieves a remarkable compactness purpose and allows the flattened pallets to be folded into a stacked state. The feature is that it is allowed to be stored in

Conventionally, this kind of pallet was made in 1973.
There is one published in Publication No. 38878. This was a folding method in which the front and rear mesh plate parts were folded inward, and then the two side mesh plate parts were stacked and folded on top of this. However, when folding the net plate portions on both sides, the column portions attached to both side edges get in the way, making it impossible to overlap them exactly.
Since the pillar portions overlap in a mountain shape, sufficient flattening cannot be achieved, and as a result, it has become completely impossible to store the required number of pallets vertically stacked on top of each other.

The present invention is configured so that when the front and rear mesh plate parts are folded, a space is formed for accommodating the column parts provided in the mesh plate parts on both sides, thereby solving the problems described above. This is characterized by its ability to eliminate the

Hereinafter, the configuration of the present invention will be explained in detail with reference to the drawings.

In the figure, 1 is a pallet base in the shape of a lattice frame, and legs 1a, 1a are fixed to both sides of the base to form spaces for inserting forks.

A pair of retractable pins 5b, 5b are housed in the housing 5a so that their tips protrude symmetrically from openings at both ends of the housing 5a so that they can freely protrude and retract. Together with both children 5
By interposing a spring 5e between b and 5b, a protruding force is given to both protruding pieces 5b and 5b so that they can freely protrude and retract. 5d is a protruding shaft for attaching a spring that protrudes from the center of the rear end surface of the sliding guide 5c.

The control body 5 having the above-mentioned configuration is installed in the column 4 by inserting its protrusions 5b, 5b into the through holes 4a, 4a in the column 4, respectively. In addition, when the column 4 is fully inserted to the bottom of the guide part 2 as shown in FIG. 4 (state where it can be used as a pallet), the pivot protrusions 5b, 5b are as shown in FIG. As shown in FIG. 2, the tip thereof is pressed against the inner wall of the guide cylinder 2 and held in a retracted state against the spring 5e, and when the column 4 is pulled up by the required amount for folding the pallet, the pivot protrusions 5b, 5b is based on the repulsive force of the spring 5e, as shown in FIGS. 4 and 7, the engagement holes 2a, 2
It is configured to push into engagement within a.

The control body 5 is adopted to achieve the purpose of rationally installing a retractable element on the column 4, and therefore, other than such means, the retractable element itself can be freely retracted and retracted via a spring as appropriate. Any form is acceptable as long as it has a suitable protrusion force.

Reference numeral 6 denotes a stopper piece protruding from a predetermined location of the columnar body 4, and is connected to the stopper groove 2b of the guide tube 2 described above.
By engaging with the column 4, the column 4 is stabilized in the inserted state.

Reference numeral 8 denotes mesh plates on both sides of the pillars 4 at the four corners, which are stretched over the respective pairs of pillars located on the right end side and the left end side of the pallet base 1; It is stretched so that it is almost flush with the outer surface of the.

Reference numerals 9 and 9 denote front and rear mesh plates formed by connecting an upper mesh plate 9a and a lower mesh plate 9b via a hinge 9c so that the front sides of the upper mesh plate 9a and the lower mesh plate 9b can be folded together, The mesh plates 9, 9 are configured to be temporarily fixed to the respective pairs of pillars 2 located on the front side and the back side of the pallet base 1 via latching metal fittings a, a and b, b. ing. Reference numerals 10 and 10 refer to pivot metal fittings connected to the lower ends of the back surfaces of the mesh plates 9, 9, which are bent at both ends of the pivot rod portion 10a and are formed on both sides of the pallet base 1. 1
It consists of a hook-shaped connecting rod part 10b that is hook-shaped along the upper inner corner part of b, 1b, and a mounting rod part 10c connected to the base end of the hook-shaped connecting rod part 10b,
The mounting rod portion 10c is fixed to the lower edge of the back surface of the mesh plates 9, 9. 11 is the said both side frame rod 1
It is a vertically ring-shaped pivot fitting fixedly installed near both ends of the pivot fittings 1b and 1b, and the pivot rod portion 10a of the pivot fitting 10 is inserted into the longitudinally groove-shaped hole so as to be rotatable and vertically movable.

The present invention has the above-mentioned structure, and when the pallet is folded for storage etc. in the assembled state shown in Figs. , b, fold the front and rear mesh plates 9, 9 in half, and remove the pallet base 1.
When tilted upward, the mesh plates 9, 9 will be attached to the pivot fittings 1.
It rotates via the pivot rod portion 10a at positions 0 and 10, and is converted into the laid down and folded state as shown in FIG. At this time, the mesh plates 9, 9 are folded inwardly due to the presence of the hook-shaped connecting rods 10b, which have supported the mesh plates 9, 9 until now. The mesh plates 9, 9 no longer exist in the space where both the pillars 4 face each other, and therefore, a folding space s of the pillars 4 is formed.

Next, if each column 4 is pulled upward by pulling up the mesh plates 8, 8 on both sides, the pivot protrusions 5b, 5 in the control body 5 attached to each column 4
When the spring 5e reaches the rectangular engagement holes 2a, 2a of the guide cylinder 2, the spring 5e is inserted into the engagement holes 2a, 2a.
(see Fig. 7), and therefore, the column 4 is restricted from being pulled up, and is now allowed to rotate around the protruding elements 5b, 5b. As a result, the column 4
will be folded as shown by the chain lines in FIGS. 5 and 10.

At this time, the columnar body 4 will lie down in the space s formed based on the folding of the front and rear mesh plates 9, 9 mentioned above.
Moreover, since the mesh plates 8, 8 on both sides stretched over the column 4 are stretched almost flush with the outer surface of the column, the above-mentioned The presence of the front and rear mesh plates 9, 9 in the folded state allows the folding thereof without causing any obstruction (see FIG. 10).

Note that reassembly is achieved based on the above-mentioned reverse operation.

According to the present invention described in detail above, when storing the column 4 when not in use, the column 4 can be folded to become significantly flattened, and the column 4 and the mesh plates on the four sides can all be made into pallets as shown in FIG. Since the pallets are folded on the base 1 and do not exceed the upper end of the guide tube 2, it becomes possible to store a large number of pallets in a stacked state. In other words, in the conventional pallet of this type, the front and rear mesh plates in the folded state become an obstacle to the folding of the columns, so the columns are folded into a mountain shape, and therefore it is difficult to stack them. Storage was deemed impossible. In contrast, the present invention
The pivot point of the front and rear mesh plates 9, 9 to the pallet base 1 is connected to the inside of the pallet base 1 via appropriate pivot fittings fixed to the lower edges of the backs of the mesh plates 9, 9. By forming the mesh plates 9, 9 on the sides, the mesh plates 9, 9 are configured to move outward of the space facing the pillars to which they are temporarily fixed and fall down, so that the folded front and rear mesh plates 9, 9 does not interfere with the folding of the column 4,
Therefore, the folding of the pallet is achieved with remarkable flatness.

Since the present invention has a simple structure and excellent practical effects as described above, its utility value is extremely high.
