Description

[Detailed description of the invention] Industrial field of application This invention is used as a pallet supporter, that is, a support structure that is installed at the four corners of a flat pallet to allow pallets to be stacked in multiple layers above and below. This invention relates to pallet supports made of metal pipes.

Prior art and its problems This type of pallet supporter is, for example,
As seen in Publication No. 52-2180, Publication No. 53-35349, Publication No. 40593 of Utility Model No. 54-40, etc., a pair of horizontal rods and leg rods at both ends form a downwardly open U-shape. It is composed of metal pipe support frames, and both leg rods of each support frame are placed at diagonal angles of the pallet so that the horizontal rods of both support frames intersect above the quadrilateral pallet for cargo handling. By removably attaching the pallets via attachment fittings, it is possible to stack the pallets loaded with cargo in multiple stages.

However, when loading cargo onto a pallet in several layers, depending on the type of cargo, the total height of the stacked cargo may be considerably lower than the internal height of the pallet supporter, but may be slightly too high to stack one more layer. This creates a large dead space in the upper part of the inner side of the pallet supporter, resulting in a problem in that space utilization during storage and cargo handling efficiency are reduced.

The object of this invention is to solve the above problems by making the pallet supporter adjustable in height.

Means for Solving the Problems For the above purpose, this invention uses a pair of metal pipe support frames 3, 3 which are configured in a cross-shaped configuration with a horizontal rod 4 and leg rods 5 extending downward from both ends thereof. In the pallet supporter having
In this case, rod inserts 7, 7 of a predetermined length are vertically provided at both ends of the horizontal rod 4, and the rod inserts 7, 7 are slidably fitted into the cylindrical portion 8 at the upper part of the leg rod 5. A flange-like stopper portion 7a is provided at the base of the rod insertion portion 7 to be in contact with the opening edge 8a of the cylindrical portion 8 of the leg rod 5.
The spacer is inserted between the opening edge 8a of the opening edge 8a and the stopper part 7a by being fitted over the rod insertion part 7, and has a structure in which a cylindrical body shorter than the rod insertion part 7 is vertically divided into two parts. A height adjusting spacer 9 is comprised of a pair of semi-cylindrical members 10 and 11, and has locking portions 12 and 13 formed on the semi-cylindrical members 10 and 11 to engage with each other when the cylindrical shapes are combined. It will be done. The main feature is a height-adjustable pallet supporter.

Function The height adjustment spacer used in this invention is
The cylindrical body is constructed by combining a pair of semi-cylindrical members and engaging the locking portions of both members with each other, and when it becomes necessary to raise the height of the pallet supporter legs, the above-mentioned insert can be used. By fitting the cylindrical body integrated into the rod part and interposing it between the opening edge of the cylindrical part and the stopper part at the base of the rod insertion part, the actual height of the leg rod is reduced by the length of the cylinder body. It is possible to increase the height.

However, with a spacer consisting of a simple cylinder,
When attaching to the insertion rod, it is necessary to completely remove the insertion rod from the cylindrical part and then insert it from the tip side of the insertion rod.After installation, it is necessary to insert the insertion rod into the cylindrical part again. Especially when the weight to be supported by the connecting part is large or when there are multiple leg rods, it is very difficult to re-insert and re-insert them due to positioning, etc. The same applies when removing the spacer when returning the rod to its original height. On the other hand, in the spacer used in this invention, the cylindrical body is divided into a pair of semi-cylindrical members, so
By pulling out the insertion rod part to a certain extent without completely removing it, and holding the pulled out part from both sides, the two semi-cylindrical members are combined and the locking parts of each other are engaged, and the cylinder is closed. It can be simply and easily attached to the body, and there is no need to completely pull out the insertion rod when removing it, and it can be installed even if the insertion rod is fitted with a retainer.

Embodiment Hereinafter, this invention will be explained based on an illustrated embodiment in which the invention is applied to a pallet supporter.

In the figure, 1 is a quadrilateral pallet for cargo handling, 2
is a pallet supporter composed of a pair of support frames 3, 3 made of metal pipes, each support frame 3 has a U-shape opened downward with a horizontal rod 4 and leg rods 5, 5 on both sides, By erecting both leg rods 5, 5 removably on the diagonal portions of the pallet 1 via mounting brackets 6, the horizontal rods 4, 4 of both support frames 3, 3 are installed.
are arranged so as to intersect with each other in a plane above the pallet 1. Therefore, the horizontal rod 4 of the support frame 3 and the leg rods 5, 5 on both sides are arranged such that the insertion rods 7, which are vertically installed at both ends of the horizontal rod 4, slide into the upper cylindrical portion 8 of the leg rod 5. A connection structure is adopted in which the pallet supporter 2 can be freely inserted and connected to each other, and the pallet supporter 2 can be separated from the pallet supporter 2 so as not to be bulky when stored or transported when not in use. is provided with a flange-shaped stopper portion 7a that contacts the opening edge 8a of the cylindrical portion 8 of the leg rod 5. still,
The connecting portion between the leg rod 5 and the mounting bracket 6 also adopts the same fitting structure as described above, so that it can be separated when not in use.

Reference numeral 9 denotes a height adjustment spacer, which is a pair of metal spacers having a structure in which a cylindrical body shorter than the rod insertion part 7 of the pallet supporter 2 is vertically divided into two, that is, the cylindrical body is divided into two in the axial direction. Semi-cylindrical member 10,1
It is composed of 1. This one semi-cylindrical member 10 has approximately triangular locking pieces 1 at two locations on the upper and lower outer surfaces of the side edges 10a, 10a on both sides thereof.
2 and 12 are welded and fixed with their acute angle portions 12a facing upward and protruding outward from the side edges. Similarly, the other semi-cylindrical member 11 has upper and lower outer surfaces 2 on both side edge portions 11a, 11a.
Approximately triangular locking pieces 13, 13 are welded and fixed to these positions with their acute angle portions 13a facing downward and protruding outward from the side edges. Therefore, when the two semi-cylindrical members 10, 11 are combined to form a complete cylinder, the locking pieces 12, 13 of the two semi-cylindrical members 10, 11 engage with each other at their acute angle portions 12a, 13a. The mounting positions and the angles and orientations of the acute angle portions 12a and 13a are set so that the parts 12 and 13 cannot be separated laterally.

In the above configuration, when it becomes necessary to increase the internal height of the pallet supporter 2 depending on the type of cargo to be loaded on the pallet 1, the horizontal rods 3 of each support frame 3
If the inserting rod 7 is pulled out from the cylindrical part 8 by pulling it upward, and the semi-cylindrical members 10 and 11 of the spacer 9 are joined to the pulled out part by sandwiching them from both sides. good. Incidentally, during this clamping, one half-cylindrical member 10 is vertically shifted so that it is lower than the other member 11, and both side edges 10a, 10a and 11 of both members 10, 11 are attached.
a, 11a and then eliminate this vertical deviation, both locking pieces 12, 13
are automatically engaged, and both members 10 and 11 cannot be separated laterally to form a complete cylindrical body as a spacer.

The spacer 9 installed in this way is interposed between the stopper part 7a of the rod insertion part 7 and the opening edge 8a of the cylindrical part 8, and its length increases the height of the leg rod 5, that is, the inner height of the pallet supporter 2. becomes higher. Therefore, by preparing several types of spacers 9 with different lengths, it is possible to adjust the inner height of the pallet supporter 2 in a plurality of stages. Also, if you want to return the inner height of the pallet supporter 2 to its original height, pull up the horizontal rod 4 a little and remove the spacer 9.
The two semi-cylindrical members 10, 11 may be shifted up and down to disengage the locking pieces 12, 13, and in this state, the two members 10, 11 may be laterally separated.

Note that the structure of the locking portions of both semi-cylindrical members in the spacer can be modified in various ways, for example, one locking portion may be configured to have a movable hook shape and be locked to the other pin-shaped locking portion. good. Furthermore, the two semi-cylindrical members are not limited to a structure in which they are completely separated, but can be pivoted so that the side edges of one side can be opened and closed via a hinge, etc., and a locking part of an appropriate structure is provided on the side edge of the other side. A structure in which the cylindrical bodies can be constructed so as to engage with each other may also be used.

Effects of the invention As described above, the pallet supporter according to the invention can adjust the height of the support frame by attaching and removing the spacer. Therefore, depending on the type of cargo to be loaded on the pallet, the inner height of the pallet supporter can be adjusted to avoid creating a large dead space above the pallet, thereby improving space utilization during storage and cargo handling efficiency. It becomes possible.

Moreover, the height adjustment spacer is divided into a pair of semi-cylindrical members that are combined to form a cylinder, and the locking portions of both members are engaged with each other to form a cylinder. When attaching and detaching the rod, there is no need to completely remove the insertion rod from the cylindrical portion, and the attaching and detaching operations can be easily performed.
