Abstract
Description
Technical Field
[0005]
[0001] The present invention relates to a nestable pallet support frame.
Background Art
[0002] In a warehouse for storing and managing goods, goods are placed on wooden or resin pallets, and the pallets with the goods are transported and stored together by a forklift. In order to efficiently arrange and store the pallets vertically, horizontally, and in all directions, pallet support frames are used (for example, Patent Document 1 and Patent Document 2).
[0003] On the other hand, when the pallet support frame is in a state where no pallets are stacked, if it is left installed as it is, it will occupy space in the warehouse. Therefore, it is disassembled or nested and moved outdoors. As the structure of a nestable pallet support frame, for example, a positive nesting type pallet support frame with a shelf for placing pallets at the bottom as in Patent Document 3 or a reverse nesting type pallet support frame with a shelf for placing pallets at the top as in Patent Document 4 is known.

Summary of the Invention
Problems to be Solved by the Invention
[0005] However, conventional nestable pallet support frames made it difficult to move them when stacked. For example, with a standard nesting type, attempting to move them in a stacked state using a forklift meant inserting the forks under the lower shelves, causing the upper part of the frame to be higher than the forklift's forks, potentially leading to instability during movement. In the case of an inverted nesting type, there was no shelf at the bottom, and the bottom pallet was placed directly on the ground, making it difficult to move all the pallets at once. It was also conceivable to add shelves to both the top and bottom of the pallet support frame, but this presented the problem of making nesting difficult.
[0006] Therefore, the present invention aims to provide a pallet support frame that can be stably moved by a forklift even when stacked, and that can be compactly nested. [Means for solving the problem]
[0007] The pallet support frame according to the present invention is A rectangular base is provided at the bottom, on which luggage can be placed, Two rectangular shelves are located at the top, spaced apart on the left and right, A beam member connects the two aforementioned shelves on the rear side, Two first support columns extend downward from the outer front corners located on the outer front side of each of the two shelves and connect to the front front corners of the base, Two second support columns extend downward from both ends of the beam member and connect to the rear side of the base, Fork claw guides provided on each of the two aforementioned shelves and It has. [Effects of the Invention]
[0008] According to the present invention, a pallet support frame can be provided that can be stably moved by a forklift even when stacked, and that can be compactly nested. [Brief explanation of the drawing]
[0009] [Figure 1] This is a schematic perspective view showing an example of the configuration of a pallet support frame according to the present invention. [Figure 2] This is a schematic perspective view showing how the pallet support frames according to the present invention are nested. [Figure 3] This is a front view showing the pallet support frames according to the present invention stacked in layers. [Modes for carrying out the invention]
[0010] The pallet support frame according to the present invention is typically installed in warehouses that store and manage goods, and serves as a base for storing wooden or resin pallets on which goods are placed. Warehouses in which the pallet support frame according to the present invention is installed include not only warehouses that store ordinary goods at room temperature, but also temperature and humidity controlled warehouses equipped with temperature and humidity control functions for storing works of art, and refrigerated and frozen warehouses for storing food.
[0011] Figures 1 and 2 show examples of the configuration of the pallet support frame 10 according to the present invention. As shown in Figure 1, the pallet support frame 10 includes a rectangular base 1 on which a load can be placed on its upper surface, two rectangular shelves (right shelf 2a, left shelf 2b) spaced apart to the left and right, a beam member 3 connecting the right shelf 2a and the left shelf 2b on the rear side, two first support columns 4a and 4b extending downward from the outer front corners 21a and 21b located on the outer front sides of the right shelf 2a and the left shelf 2b, respectively, and connecting to the front corners (1a and 1b) on the front side of the base 1, two second support columns 5a and 5b extending downward from both ends of the beam member 3, and connecting to the rear side (second side 12) of the base 1, and a pair of fork claw guides (6a and 6b) provided on the right shelf 2a and the left shelf 2b, respectively. In this specification, the side facing both the first support columns 4a and 4b is referred to as the front, the side facing both the second support columns 5a and 5b is referred to as the rear, the right side when viewed from the front is referred to as the right, and the left side when viewed from the front is referred to as the left.
[0012] Base 1 is located at the bottom, as shown in Figure 1. Base 1 is for placing cargo (cargo on a pallet) on its top surface and has a rectangular (or square) shape in plan view. The outer frame of Base 1 is composed of a first side 11 on the front side, a second side 12 on the back side, a third side 13 on the right side, and a fourth side 14 on the left side. The shape of each side may be cylindrical or prism-shaped, but prism-shaped is preferred. As shown in Figure 1, crossbars may be provided as needed. The size of Base 1 can be appropriately determined according to the size of the pallet to be loaded.
[0013] The shelves located at the top consist of a right shelf 2a and a left shelf 2b, which are spaced apart from each other. The right shelf 2a and the left shelf 2b are for placing cargo (cargo on pallets) on their top surfaces, and each has a rectangular (rectangle or square) shape in plan view. The size of the right shelf 2a and the left shelf 2b can be appropriately determined according to the size of the pallets to be loaded, but it is preferable that the overall shape formed by the right shelf 2a and the left shelf 2b is the same shape as the base 1.
[0014] As shown in Figure 1, the beam member 3 connects the right shelf 2a and the left shelf 2b on the rear side. However, the space between the right shelf 2a and the left shelf 2b on the front side is left open and unconnected. In other words, the shape formed in plan view by the right shelf 2a, the left shelf 2b and the beam member 3 is U-shaped. The shape of the beam member 3 may be cylindrical (tubular) or rectangular prism (tubular), but a rectangular prism (tubular) shape is preferred.
[0015] The first columns 4a and 4b extend downward from the front outer corners (21a, 21b) located on the outer sides of the front sides of the right shelf 2a and the left shelf 2b, respectively, and are connected to the front corners (1a, 1b) on the front side of the base 1, respectively. Specifically, as shown in FIG. 1, the first columns 4a and 4b are connected to the right side surfaces and the left side surfaces at the front outer corners 21a and 21b of the right shelf 2a and the left shelf 2b, respectively. And the first columns 4a and 4b are connected to the right side surfaces and the left side surfaces (the right side surface of the third side 13 and the left side surface of the fourth side 14) at the front corners 1a and 1b on the front side of the base 1, respectively. It is preferable that the distance between the left side surface of the first column 4a and the right side surface of the first column 4b is larger than the length of the base 1 in the left-right direction. The shapes of the first columns 4a and 4b may be cylindrical (tubular) or prismatic (tubular), but a prismatic (tubular) shape is preferable.
[0016] As shown in FIG. 1, the second columns 5a and 5b extend downward from both end sides of the beam member 3 and are connected to the side (the second side 12) on the back side of the base 1. The shapes of the second columns 5a and 5b may be cylindrical (tubular) or prismatic (tubular), but a prismatic (tubular) shape is preferable. Also, it is preferable that the distance from the right side surface of the second column 5a to the left side surface of the second column 5b is smaller than the interval between the right shelf 2a and the left shelf 2b (the distance between the left side surface of the right shelf 2a and the right side surface of the left shelf 2b). As shown in FIG. 1, a cross bar connecting the second column 5a and the second column 5b may be provided as necessary.
[0017] As shown in Fig. 1, the fork claw guides 6a and 6b are provided on the right shelf 2a and the left shelf 2b, respectively. The fork claw guides 6a and 6b function as guides when inserting the claws of the forklift from the front to the back into the right shelf 2a and the left shelf 2b. In the illustrated configuration, the fork claw guides 6a and 6b are provided closer to the center of the pallet support frame 10, but are appropriately determined according to the width of the claws of the forklift. In the present embodiment, the fork claw guides 6a and 6b may have any shape as long as they function as guides when inserting the claws of the forklift, but as shown in Fig. 1, it is preferable that they have a square tube shape with insertion ports (61a, 61b) for inserting the claws of the forklift from the front. Note that the fork claw guides 6a and 6b are not limited to the square tube shape shown in Fig. 1, and for example, they may have a U-shape with an open lower side in cross-section, or they may have an L-shape in cross-section. < 4a, 4b First pillar 5a, 5b Second pillar 6a, 6b Fork tine guides 7 Palettes 8 Luggage 10 Pallet support frame 11 First side 12 Second side 13 Third side 14.
