【Example】
Examples of the present invention will be described below. However, the present invention is not limited to these examples as long as the gist of the present invention is not exceeded.
[0008]
First, the overall configuration of a four-way synthetic resin pallet P as an example will be described with reference to FIGS.
[0009]
Reference numeral 1 denotes an upper deck configured in a rib structure with lattice-shaped ribs 1 a, corner girders 2 are arranged at four corners of the upper deck 1, and intermediate girders 3 are arranged between the corner girders 2. Further, a central girder 4 is arranged at the center of the upper deck 1. The lower deck 5 includes a connecting portion 6 that connects the corner beam 2 and the intermediate beam 3, and a connecting portion 7 that connects the intermediate beam 3 and the central beam 4. A substantially rectangular portion 8 surrounded by a connecting portion 6 that connects the intermediate girder 3 and a connecting portion 7 that connects the intermediate girder 3 and the central girder 4 has a bottomed structure (hereinafter, this portion). Is referred to as a bottomed portion 8). Two fork insertion holes 9 are formed between the corner beam 2 and the intermediate beam 3 on each side of the pallet P made of synthetic resin. With such a structure, a four-way synthetic resin pallet P is configured.
[0010]
Next, the configuration of the connecting portion 6 that connects the corner beam 2 and the intermediate beam 3 will be described with reference to FIGS. 3 and 4.
[0011]
The connecting portion 6 that connects the corner beam 2 and the intermediate beam 3 extends from the horizontal plate portion 6a and both ends of the horizontal plate portion 6a toward the side opening 9a of the fork insertion hole 9 and the bottom portion 8 direction. Each of them is formed in a substantially trapezoidal shape by the inclined plate-like portion 6b inclined downward. Further, an appropriate number of ribs 6c are suspended in a lattice shape on the lower surfaces of the horizontal plate-like portion 6a and the inclined plate-like portion 6b. 6d is a through-hole drilled in the horizontal plate-like portion 6a and the inclined plate-like portion 6b as necessary, and rain water and washing water on the horizontal plate-like portion 6a and the inclined plate-like portion 6b are directed downward. It is for draining.
[0012]
Next, the configuration of the connecting portion 7 that connects the intermediate beam 3 and the central beam 4 will be described with reference to FIGS. 3 and 5.
[0013]
The connecting portion 7 that connects the intermediate beam 3 and the central beam 4 is composed of a plurality of bars 7 a, 7 b, 7 c extending from the intermediate beam 3 toward the central beam 4. 3 and 5 show three crosspieces 7a, 7b, and 7c. Of course, three or more bars can be provided.
[0014]
A crosspiece 7a (hereinafter referred to as a central crosspiece) located in the center is suspended so as to extend from the intermediate girder 3 toward the central girder 4 at the center and both ends of the horizontal plate-like portion 71 and the lower surface of the horizontal plate-like portion 71. It is comprised by the plate-shaped leg part 72 provided. Further, bars 7b and 7c (hereinafter referred to as inclined bars) disposed on both sides of the central bar 7a and in parallel with the central bar 7a with a predetermined gap d1 are formed by a plate-shaped inclined portion 73, a plate The plate-like leg portion 74 is provided at the center and both ends of the lower surface of the inclined portion 73 so as to extend from the intermediate beam 3 toward the center beam 4. The plate-like inclined portions 73 of the inclined bars 7b and 7c are inclined downward in a direction away from the central bar 7a. In the embodiment shown in FIG. 5, the central bars 7a of the inclined bars 7b and 7c are inclined. The height h1 on the side is formed substantially the same as the height h2 of the central rail 7a. The width w1 of the central beam 7a (the width in the direction perpendicular to the central beam 4 extending from the intermediate beam 3 toward the central beam 4) is wider than the gap d1 between the central beam 7a and the inclined beams 7b and 7c. It is formed to become. The horizontal plate-like portion 71 of the central crosspiece 7a and the plate-like inclined portion 73 of the inclined crosspieces 7b and 7c are provided with rainwater and washing water below the horizontal plate-like portion 71 and the plate-like inclined portion 73 as needed. A through-hole 7d for draining can be formed.
[0015]
As described above, since the connecting portion 6 that connects the corner beam 2 and the intermediate beam 3 is formed with the inclined plate-like portion 6b at the end portions of the horizontal plate-like portion 6a that are positioned in the front and rear directions in the fork insertion direction. When the fork base f1 of the handlift F as shown in FIG. 6 is inserted into the fork insertion hole 9, the front wheel f2 disposed on the fork base f1 extends along the inclined plate-like portion 6b. Thus, the connecting portion 6 can be crossed smoothly and easily.
[0016]
Similarly, the connecting portion 7 that connects the intermediate beam 3 and the central beam 4 is also provided with inclined beams 7b and 7c on both sides of the center beam 7a, so that the fork base f1 of the handlift F is connected to the fork insertion hole. 9, the front wheel f2 disposed on the fork base f1 may pass over the connecting portion 7 smoothly and easily along the plate-like inclined portion 73 of the inclined bars 7b and 7c. it can. Further, since the width w1 of the central beam 7a is formed wider than the gap d1 between the central beam 7a and the inclined beam 7b, 7c, in other words, between the central beam 7a and the inclined beam 7b, 7c. Since the gap d1 is formed to be narrower than the width w1 of the central rail 7a, even if the front wheel f2 of the handlift F falls into the gap d1, it can easily come out.
[0017]
In the embodiment of the connecting portion 7 shown in FIG. 7 for connecting the intermediate beam 3 and the central beam 4, the height h1 of the inclined beam 7b, 7c on the central beam 7a side is set to the height h2 of the central beam 7a. It is a lower one. Since the height h1 on the side of the central beam 7a of the inclined beam 7b, 7c is made lower than the height h2 of the central beam 7a, the front wheel f2 of the hand lift F is located between the central beam 7a and the inclined beam 7b, 7c. Even if the hand lift F is accidentally jacked up and the fork base f1 is raised in a state where it falls into the gap d1, the fork base f1 comes into contact with the lower surface of the upper deck 1 and is lowered to the front wheel f2. When force is applied, component force in the direction of the inclined beam 7b lower than the central beam 7a acts on the front wheel f2, and the front wheel f2 can be moved downward along the inclined beam 7b. Accordingly, when the fork base f1 and the front wheel f2 are jacked up, the front wheel f2 may escape along the inclined beam 7b even if it is accidentally pinched between the upper deck 1 and the connecting portion 7. Since it can do, it can prevent that the connection part 7 is damaged.
[0018]
In the embodiment described above, an example of a four-way pallet P is shown, but the present invention is naturally applicable to a two-way pallet.
[0019]
【The invention's effect】
Since the present invention has the above-described configuration, the following effects can be achieved.
[0020]
Since the width of the crosspiece is wider than the gap between the crosspieces, the strength of the connecting part that connects the central girder and intermediate girder of the lower deck is improved, and the wheel of the hand lift does not fall down. The operability of the lift is improved.
[0021]
Since the height of the crosspiece is configured to gradually decrease from the center to both sides, even if the handlift wheel is accidentally jacked up while the wheel of the handlift remains in the gap between the crosspieces Therefore, it is possible to prevent a trouble that the wheel of the handlift falls from the crosspiece, and thus the crosspiece constituting the connecting portion connecting the central beam and the intermediate beam of the lower deck is broken.
