Description

[Detailed description of the invention] (Field of industrial application) This invention is a pallet supporter, that is, when multiple pallets loaded with cargo are stacked one above the other, it is attached to the lower pallet to support the upper pallet. This relates to a pallet support structure used in

(Prior Art) Conventionally, this type of pallet supporter is known, for example, as shown in Japanese Utility Model Application Publication No. 54-60854 and Japanese Utility Model Application Publication No. 54-60855. The basic structure of all of these known pallet supports is a pair of supports formed in a downward U-shape by an upper horizontal rod 22 and support legs 23, 23 at both ends, as shown in FIG. By inserting the lower ends of the supporting legs 23 into the short support tubes 25 of the mounting brackets 24 attached to the four corners of the pallet P, the frames 21, 21 are combined into an X-shape in plan view and placed on the pallet. It is now ready to be erected. However,
The inner diameter of the support tube 25 is made considerably larger than its outer diameter so that the support leg 23 can be easily inserted, and a collar piece 26 fixed to the outer periphery of the support leg 23 is attached to the upper end surface of the support tube 25. Since the support legs are supported by touching each other, when the support frame is erected, it wobbles, and the whole structure is somewhat unstable, which creates a sense of danger when stacking pallets in multiple stages. . In addition, the pallet P usually has a dimensional error of about ±5 to 7 mm in width and depth, and since the distance between the diagonal support tubes 25 and 25 is not always strictly constant, the support frame 2
The disadvantage was that it was often difficult to attach and detach the 1 and 21.

(Purpose of the invention) The purpose of this invention is to eliminate the above-mentioned drawbacks. The lower end of the support leg can be easily inserted and removed from the support tube of the mounting bracket, regardless of slight dimensional errors in the pallet, and the stability of the support leg in the inserted state is further improved. The purpose is to make something.

(Structure of the invention) For the above purpose, the pallet supporter according to the invention includes an insertion portion with a reduced diameter via an inclined step at the lower end of each support leg in a pair of downward U-shaped support frames. is formed, and the support cylinder of the mounting bracket attached to the four corners of the pallet has an inner diameter that allows the insertion part to be loosely inserted thereinto, and has an inclined surface at the upper end corresponding to the inclined step part. It is characterized by having a structure in which an enlarged tube portion is formed into which the support leg can be loosely inserted through the support stepped portion.

(Example) The configuration of this invention will be further explained in Figures 1 to 3 below.
Description will be given based on the embodiment shown in the figures.

Reference numerals 1 and 1 refer to a pair of support frames made of pipes formed in a downward U-shape by an upper horizontal rod 2 and support legs 3 at both ends, and the lower end of each support leg 3 has a diameter reduced by swaging. A reduced insertion portion 4 of a predetermined length is provided via an inclined step portion 5. The inclined step portion 5
The angle of inclination is approximately 30 to 60 degrees with respect to the horizontal plane, and preferably approximately 45 degrees. The lower end of the insertion portion 4 may be formed in a tapered shape with a smaller diameter toward the bottom in order to facilitate insertion into a support tube, which will be described later. Note that the upper horizontal bars 2, 2 of each support frame 1, 1 are formed with an upward recess 7 and a downward recess 8, respectively, and by engaging these, the upper surfaces of the upper horizontal bars 2, 2 can be made flush. The support frames 1, 1 can be combined in an X-shape in plan view. In addition, a reinforcing outer cylinder 9 of a predetermined length is sheathed in the center of the upper horizontal rod 2 in order to compensate for the bending strength reduced by the formation of the recesses 7 and 8.

Reference numeral 10 denotes a mounting bracket for the support frames 1, 1, which includes mounting parts 11 that are U-shaped in plan and fit into the ends of the end girders at the four corners of the pallet P, and short parts welded and fixed to the outer surface of one side of the mounting parts 11. It consists of a cylindrical support tube 12, and the inner peripheral surface of the support tube 12 has a diameter slightly larger than that so that the insertion part 4 at the lower end of the support leg 3 of the support frame 1 can be loosely inserted therein. There is. Further, at the upper end of the support tube 12, an enlarged pipe portion 13 is formed into which the support leg 3 can be loosely inserted via an inclined support step 6 corresponding to the above-mentioned inclined step 5. Similarly, an enlarged tube portion 15 is formed at the lower end of the support tube 12 via an inclined stepped portion 14, so that when manufacturing the mounting bracket 10, the support tube 12 can be flipped upside down and installed in any direction. being done.

(Effects of the invention) Since this invention has the above-described configuration, the mounting brackets 10 are attached to the four corners of the pallet P, and the lower end insertion portion 4 of each support leg 3 is attached to the support cylinder 12.
When attaching the support frames 1, 1 by inserting the lower end of the insertion part 4 into the enlarged tube part 13 at the upper end of the support cylinder 12, the insertion part 4 is then guided by the inclined support step part 6. can be correctly guided and fitted into the support cylinder 12, and the support cylinders 1 diagonally of the pallet P can be inserted into the support cylinder 12.
Even if there is some error in the distance between the support frames 1 and 12, the support frames 1 and 1 can be easily attached.

In addition, in the state after installation, the inclined step portion 5 of the support leg 3 is supported by the support step portion 6 on the support cylinder 12 side having a corresponding slope, so that the upper pallet P is stacked on the support frames 1, 1. The more the load is applied, the more stable the attachment state of the support leg 3 to the mounting bracket 10 becomes. Therefore, the support frames 1, 1 do not wobble and are extremely stable, improving safety and increasing the permissible range of stacking and multi-tier stacking of heavy-load upper pallets.

Furthermore, when disassembling the pallet supporter, if no load is applied to the support frame 1, the supporting legs 3
Since the sloped step 5 at the lower end is simply supported on the support step 6 of the support tube 12,
The insertion part 4 can be easily removed from the support tube 12, and the disassembly operation can be performed extremely easily.

As described above, compared to conventional products, this invention makes it possible to easily attach and detach the support frame regardless of the dimensional error of the pallet, while also exhibiting outstanding stability when in use. It has great practical effects.
