Description

[Detailed explanation of the invention] (Field of industrial application) This invention is a pallet supporter, more specifically, a pallet supporter that is attached to the lower pallet to support the upper pallet when multiple loaded pallets are stacked vertically. This article relates to the pallet support used for this purpose.

(Prior Art) Conventionally, as this type of pallet supporter, those shown in Japanese Utility Model Publication No. 48-39814, Japanese Utility Model Publication No. 52-2180, etc. have been commonly used. This known palette supporter is
As shown in FIG. 5, a pair of support frames 20, 20 are formed in a downward U-shape by an upper horizontal rod 22 made of a round pipe and supports 21, 21 at both ends thereof.
The upper concave portions and the downward concave portions formed in the center portions of the upper horizontal bars 22, 22 are engaged with each other to form an X-shaped plane, and the lower ends of each support column 21 are attached to the four corners of the pallet P with the mounting brackets 23. It is said to have been erected through the bridge. However, such a palette
The supporter has the disadvantage that it is somewhat inferior in strength,
Particularly when loading pallets with a relatively large weight are stacked on the upper stage, the support frame 2 with a long span is
The upper horizontal rod 22 of 0 tends to bend downward, and the supporting legs tend to bend outward as well, resulting in a short service life.

For this reason, as shown in Japanese Utility Model Publication No. 56-48031, it has been proposed to strengthen the central part of the upper horizontal rod by forming it with a double pipe. However, it has not been possible to completely eliminate the risk of downward bending deformation of the upper transverse rod when a large load is applied.

In view of the above-mentioned problems, this invention aims to reduce the risk of bending deformation by further shortening the span of the upper support member corresponding to the upper transverse rod, and also to reduce the risk of bending deformation of the upper support member. The purpose is to prevent deformation by increasing the strength of the rod by using two rods.

(Structure of the invention) In other words, the pallet supporter according to the invention consists of four pillars erected at the four corners of the pallet, and a receiving frame removably attached to these pillars. , the receiving frame is formed in a U-shape in plan view with a rear frame portion and left and right side frame portions located inward from a vertical plane on which the circumferential side of the pallet exists; The device is characterized in that each part is formed as a double type with inner and outer frame rods arranged in parallel with their upper surfaces located on the same plane.

(Embodiment) In the illustrated embodiment, the pallet supporter according to the invention includes four pillars 1 erected at the four corners of the pallet P, and a receiving frame detachably attached to these pillars 1. 2.

Each of the receiving frames 2 has a rear frame portion 3 located inward from a vertical plane on which the circumferential surface of the pallet P exists.
The left and right side frame portions 4, 4 are formed into a U-shape in plan view. Moreover, the rear frame portion 3 and the left and right side frame portions 4, 4 have outer frame rods 3a, 4a made of square pipes and arranged in parallel with their upper surfaces located on the same plane, and inner frame rods 3a, 4a made of square pipes as well. frame rod 3
b and 4b, it is formed as a compound type. That is, on the inner surface of both ends of the outer frame rod 3a of the rear frame portion 3, both the inner and outer frame rods 4a, 4b of the left and right side frame portions 4, 4 are attached.
Both end surfaces of the inner frame rod 3b of the rear frame section 3 are welded and fixed to the rear inner surfaces of the inner frame rods 4b, 4b of the both side frame sections 4, 4, and both ends of the inner frame rod 3b of the rear frame section 3 are welded and fixed. The front ends of the outer frame rods 4b, 4b are welded and fixed to the rear surfaces of the tips of the outer right angle bent portions 5, 5 formed at the front ends of the inner frame rods 4b, 4b.

6 is both the inner and outer frame rods 3a, 3 of each of the above-mentioned frame parts 3, 4.
b, 4a, and 4b are short pipes for connecting them interposed at appropriate locations.

Moreover, short cylindrical female fitting members 7 are vertically attached to both ends and both corners of the receiving frame 2. This female fitting member 7 is made of a die-cast molded product, and is a fitting tube having a tapered vertical hole 8 whose inner peripheral surface gradually decreases in diameter as it reaches the upper end, as shown in FIG. 7a, and a cylindrical attachment part 7b that protrudes laterally from the outer peripheral surface of the part 7a. It is fixed to the receiving frame 2 by fitting into the opening at the tip and openings at both ends of the outer frame rod 3a of the rear frame part 3, and welding the mating parts. On the other hand, at the upper end of the support column 1, a male fitting part 10 is formed which corresponds to the vertical hole 8 whose diameter gradually decreases as it reaches the upper end by swaging. By fitting the male fitting part 10 into the vertical hole 8 of the female fitting member 7, it can be detachably attached to the receiving frame 2.

The means for attaching the pallet supporter to the pallet P in the above embodiment is the same as the conventional one. That is, a mounting bracket 12 having a short support tube 11 is attached to the four corners of the pallet P, and the pallet P can be attached by inserting the lower end of each support column 1 into the support tube 11 of the mounting bracket 12. .

(Effects of the invention) This invention achieves the following effects by having the above-mentioned configuration.

First, the receiving frame attached to the four pillars is U-shaped in plan view. Therefore, when the upper pallet is placed on top of the pallets and stacked, the load is applied to each of the two pallets adjacent to each other in the left and right, front and rear, located at the shortest distance, via the rear frame and left and right side frames of the receiving frame. Although the pallet supporter is distributed and supported by the pillars, there is a risk that it may bend and deform due to the load because the span of the rear frame part and the side frame part is shorter than that of the upper horizontal rod of the conventional pallet supporter mentioned above. can be reduced. Moreover, since both the rear frame portion and the side frame portions are formed in a double manner with two inner and outer frame rods, they are strong in themselves and have little risk of bending deformation, and each frame portion Since both the inner and outer frame rods are arranged in parallel with their upper surfaces on the same plane, the receiving area for the upper pallet to be stacked on them is large, and the lower pallet is slightly Even if the device is placed at a position shifted from its position in the front-rear direction or left-right direction, it can be safely supported without any problem. Furthermore, since the receiving frame has a U-shape in plan view and is open on the front side, the receiving frame does not become an obstacle when loading cargo onto a pallet, which is advantageous in terms of work.
In addition, since the supports are designed to be detachable from the receiving frame, the pallet supporter itself can be advantageously made smaller and more compact when transporting and storing it.
