Description

[Detailed explanation of the invention] (Industrial application field) This invention is a pallet support 7. More specifically, when multiple pallets loaded with cargo are stacked vertically, the support is attached to the lower pallet and the upper pallet is It relates to a pallet support structure used to support a pallet.

(Prior Art) The basic structure of this type of pallet supporter, which has been most commonly used in the past, is that supporting legs 23 are welded to both ends of an upper horizontal rod 22, as shown in FIG. A pair of support rods 21 formed in a downward U-shape are combined into an X-shape in plan view by engaging the upward recess 27 and the downward recess 28 formed at the center of the upper horizontal rod 22 with each other. , the lower end of each support leg 23 was inserted into the support cylinder 25 of the receiving bracket 24 attached to the four corners of the pallet P to stand upright. issue).

However, in such a conventional pallet supporter, since the support frame 21 is a large U-shaped product, the support frame is very bulky and difficult to store or transport when not in use. While it occupies a large floor space and space,
When transporting it, there are drawbacks such as only a small amount can be loaded on the platform of a truck or the like.

Incidentally, when bulk loading is carried out on a truck with a liter capacity, the support frame 21 can only load about 39,200 kg, which makes freight costs relatively high, which is a major factor in increasing product costs.

Therefore, in order to improve such drawbacks, the inventor of the present application has already proposed a technique disclosed in Japanese Utility Model Application Publication No. 54-60854 as another conventional technique.

That is, as shown in FIGS. 5 and 6, in this prior art, the upper horizontal rod 22 and the support leg 23 are formed separately, and the female fitting member 30 fixed to both ends of the upper horizontal rod is tapered. A pallet supporter in which a tapered male fitting part 32 corresponding to the vertical hole 31 formed at the upper end of the support leg 23 is fitted into a shaped vertical hole 31 so that the two can be connected during use. be.

Such a conventionally proposed pallet supporter is
and the support leg 23 are connected by fitting their tapered surfaces together, so the more the load is applied from above due to the stacking of pallets on the upper stage, the more the fitting portions are connected. While this has the advantage of strengthening the engagement and increasing the connection strength and achieving excellent safety without the risk of rattling, on the other hand, because the engagement is extremely strong, When disassembling it again, the above-mentioned fitting part does not come off easily, and it is necessary to remove it by hitting both ends of the upper horizontal rod 22 from below with a hammer, for example. Such work requires applying force from the bottom to the top. The problem was that it was not only difficult to perform, but also required a great deal of force.

(Purpose of the invention) In order to solve the above-mentioned drawbacks, this invention is designed to allow external striking force to be applied directly to the upper end of the support leg from above using a hammer or the like, thereby removing the support leg from the horizontal rod. It is intended to be easily removable.

(Structure of the device) Accordingly, this device includes a tapered male fitting portion formed at the upper end of the support leg in the tapered vertical hole of the female fitting member fixed to both ends of the upper horizontal rod. In the pallet supporter that is fitted into the pallet supporter and forms a downward U-shaped support frame, a notch is formed in the upper end peripheral wall of the female fitting member, and in the fitted state, the upper end of the male fitting part is inserted into the notch. It is characterized by the fact that it is made to appear in front of the viewer.

(Example) Hereinafter, embodiments of this invention will be described based on the drawings.

In the embodiment shown in FIGS. 1 to 3, each of the pair of downward U-shaped support frames 1, 1 has an upper horizontal rod 2 and supporting legs 3, 3 at both ends formed separately. Short cylindrical female fitting members 4 are vertically sloped at both ends of the upper horizontal rod 2.

This female fitting member 4 is made of a die-cast molded product,
The vertical hole 4a is formed in a tapered shape with an inner diameter that gradually decreases as it reaches the upper end, and a cut-out portion 4b that is semicircular in plan view is formed on the upper end peripheral wall, and protrudes laterally on the upper peripheral side. It has a mounting insertion part 5, and is integrally fixed to the upper horizontal bar 2 by tightly fitting the insertion part 5 into the opening of the upper horizontal bar 2 made of pipe and welding the mating part exposed to the outside. It is done.

On the other hand, at the upper end of the pipe support leg 3, a tapered male fitting part 6 corresponding to the vertical hole 4a whose diameter is gradually reduced toward the upper end by swage processing is formed. When the male fitting part 6 is fitted into the vertical hole 4a, the upper end 6a of the male fitting part 6 faces the notch part 4b.

Therefore, the fitting can be removed and easily disassembled by hitting the upper end 6a of the male fitting part 6 facing into the notch 4b from above with a hammer or the like.

Although the slopes of the circumferential surfaces of the vertical hole 4a and the male fitting portion 6 are shown slightly exaggerated in the drawings, in reality, it is preferable to set the slope to about 1 to 3 of 5.

If this slope is too large, there is a risk that the connection between the upper horizontal rod 2 and the supporting leg 3 will become uncertain; on the other hand, if it is too small, it will not only be difficult to fit together easily during assembly, but also when attempting to disassemble it. It may become difficult to remove the supporting legs 3.

A pair of support frames 1, 1 that are paired with each other have an upward recess 7 and a downward recess 8 formed in the center of each upper horizontal rod 2, and by meshing these, both support frames 1, 1
The upper surfaces of the upper horizontal rods 2, 2 are flush with each other so that they 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.

The means for attaching the support frame 1 to the pallet P is the same as the conventional one.

That is, a mounting bracket 11 having a short support cylinder 10 is attached to the four corners of the pallet P, and the lower end of each support leg 3 is inserted into the support cylinder 10 of this mounting bracket 11.

Reference numeral 12 is a collar that regulates the amount of insertion.

When using the above-mentioned pallet supporter, first attach the mounting brackets 11 to the four corners of the pallet P, set the support legs 3 on each of the support tubes 10, and then attach a pair of support legs 3 at diagonal positions.
3, and the upper horizontal bars 2, 2 are installed so as to intersect in an X-shape in plan view, and the next pallet P is stacked on these upper horizontal bars 2, 2.

(Effect of the invention) Since this invention has the above-mentioned configuration,
To disassemble the upper horizontal rod 2 and the supporting leg 3 when not in use, the fitting can be easily removed by lightly tapping the upper end 6a of the male fitting part 6 facing into the notch 4b from above with a hammer or the like. Since you only need to apply force in a natural direction from top to bottom, there is an advantage that disassembly work can be carried out effortlessly and smoothly without requiring much force.

Also, during assembly, the connection between the upper crossbar 2 and the supporting leg 3 is extremely easy since the tapered surfaces are used to connect each other.

In addition, since the upper horizontal rod 2 and the support legs 3 at both ends of each support frame 1 are made separately and are configured to be connected when in use, the upper horizontal rod 2 and the supporting legs 3 at both ends of each support frame 1 are made separately. By separating the support legs 2 and 3 and arranging them parallel to each other, a very compact state can be achieved.

Therefore, it does not have the disadvantage of taking up a large amount of space when stored like conventional products, and when transported by truck or ship, it is possible to increase the actual loading capacity and save on transportation costs, especially if the product is far away from the place of manufacture. The product does not have the disadvantage that transportation costs greatly increase the price even when sold to remote areas, and has the advantage of being suitable for overseas export, which had previously been economically constrained.
