[Invention of Claim 1]
In the resin pallet according to the first aspect, the lower end portion of the angle material as the support is inserted and attached to the angle material insertion holes formed in the four corner beams of the deck board. Here, instead of the pipe insertion hole in the conventional resin pallet, an angle material insertion hole having an L-shaped section is simply provided, and the tilting is regulated by sandwiching the angle material on the inner surface of the angle material insertion hole. Since the insertion hole molding core for molding the inside of the angle material insertion hole in the molding pallet of the resin pallet is thin, it cannot withstand the resin pressure and the shape can be unstable. On the other hand, in the resin pallet of the present invention, a pair of tilt restricting protrusions are provided on the inner surface of the angle member insertion hole, and the tilt of the angle member is restricted by the pair of tilt restricting protrusions. The insertion hole forming core can be made thicker by widening the part other than the part provided with the pair of tilt regulating protrusions in the angle member insertion hole. Thereby, the resin pallet having the angle member insertion holes can be formed into a stable shape. According to the present invention, since the lower end portion of the support column is composed of only the angle member, it is possible to attach the support column to the resin pallet only by inserting the support member into the angle member insertion hole. It is possible to eliminate the protruding portion of the column from the resin pallet to the side. In addition, the upper surface opening of the angle material insertion hole has an L shape that is open along the upper surface corner of the deck board, so the corner of the angle material and the corner of the deck board can be matched, The dead space by the support | pillar which became a problem conventionally can be reduced.

Since the second butting wall is reinforced, it is possible to prevent the angle material insertion hole from being broken by the angle material.

[Inventions of Claims 2 , 3 and 5 ]
According to the configuration of claim 2 , when the resin pallet is placed on the column of another resin pallet, even if the upper end of the column is shifted to the center side of the resin pallet, the L-shaped lower end wall The upper end surface of the column can be received. Moreover, according to the structure of Claim 3 and 5, the support strength with respect to an angle material can be made high.

[Invention of claim 4]
According to the configuration of the fourth aspect, the tilt restricting protrusion protrudes the outer wall of the spar into the angle material insertion hole, and forms the inner surface of the expanded structure, and the angle material insertion hole. The insertion hole molding core that molds the inside is joined through the core joint hole formed on the tip surface of the tilt restricting protrusion, so that the slide core and the insertion hole molding core reinforce each other, and the resin pressure Deformation can be prevented.

[Invention of claim 6 ]
According to the structure of Claim 6, since the four support | pillars attached to a resin-made pallet are comprised with the angle material of predetermined length, while being able to manufacture a support | pillar cheaply, when not in use, the support | pillars are connected. It can be put together to make it compact.

The flat partition wall 36 is disposed in parallel with one outer wall 30A and is orthogonal to the other outer wall 30B. Further, the flat partition wall 36 is formed in the entire vertical direction of the girder 21. Of the first and second regions R1 and R2, the second region R2 on the side away from the corners of the pair of outer walls 30A and 30B is, for example, in the horizontal direction along the flat plate dividing wall 36. It is divided into four rooms 25. Specifically, three upper end partition walls 39A are provided in parallel at the upper end between the flat partition wall 36 and the fork guide side wall 30C facing each other (see FIG. 8). Moreover, as shown in FIG. 6, three lower end partition walls 39B are passed in parallel between the lower end portions of the flat partition wall 36 and the fork guide side wall 30C (see FIG. 7). The region R2 is divided by the upper and lower upper partition walls 39A and 39B, and four rooms 25 are formed. In addition, the upper surface or the lower surface of each room 25 is alternately closed by the ceiling wall 40A or the lower wall 40B in the arrangement direction of the rooms 25.

  In addition, in the intermediate part of the height direction of the girder part 21, the whole several room 25 is mutually connected. Further, drain holes are formed through the ceiling wall 40A and the lower surface wall 40B, as well as the rectangular ceiling wall 41, the L-shaped lower end wall 42, and the like described below.

  As shown in FIG. 5, the first region R <b> 1 of the girder 21 is divided into an angle member insertion hole 23 and a reinforcing portion 21 </ b> H according to the present invention by an angle inner support wall 37. The angle inner support wall 37 is formed in the entire vertical direction of the girder 21, and is formed between a pair of flat plate walls 37A and 37B parallel to the pair of outer walls 30A and 30B, and an angle between the flat plate walls 37A and 37B. It is comprised from the chamfering wall 37C arrange | positioned in the part.

  The reinforcing portion 21H is arranged on the center side of the deck board 11 (see FIG. 1) with respect to the angle inner support wall 37, and the inside is further divided into a plurality of rooms. Specifically, a pair of upper end partition walls 38A, parallel to the flat plate walls 37A, 37B of the angle inner support wall 37, are provided on the upper end portion of the beam portion 21 from the angle inner support wall 37 to the center side of the deck board 11. 38A are provided and are orthogonal to each other. The upper surface of the rectangular chamber 26 surrounded by the upper end partition walls 38A, 38A, the flat plate dividing wall 36, and the fork guide side wall 30D is closed by the rectangular ceiling wall 41.

  A pair of lower end partition walls 38B, 38B are provided at positions slightly shifted from the pair of upper end partition walls 38A, 38A at the lower end of the girder 21 and are orthogonal to each other. The lower surface of the L-shaped column adjacent room 24 surrounded by the lower end partition walls 38B and 38B, the angle inner support wall 37, the fork guide side wall 30D, and the flat partition wall 36 is the L-shaped lower end wall 42 (see FIG. 4). ). Further, as shown in FIGS. 5 and 7, the column adjacent room 24 is formed by a diagonal wall 35 that is interposed between the chamfered wall 37 </ b> C of the angle inner support wall 37 and the joint portion of the upper end partition walls 38 </ b> A and 38 </ b> A. It is divided into two.

  As shown in FIG. 5, the angle member insertion hole 23 is surrounded by a pair of outer walls 30A and 30B, an angle inner support wall 37, a flat plate dividing wall 36, and a fork guide side wall 30D, as shown in FIG. As described above, an L-shaped upper surface opening 23 </ b> K opened along the upper surface corner of the deck board 11 is provided. As shown in FIG. 9, a first abutting wall 32 capable of abutting the lower end surface 90 </ b> D of the angle member 90 is formed in the inner portion (lower end portion) of the angle member insertion hole 23. In addition, in the first abutting wall 32, concave portions 33 and 33 are formed in a recessed manner in two places on both sides of the corners of the outer walls 30A and 30B. Moreover, the lower surface of these recessed parts 33 is obstruct | occluded with the 2nd abutting wall 34 which concerns on this invention.

  On the inner surface of the angle member insertion hole 23, a pair of tilt restricting protrusions 31, 31 are formed to protrude. Each of these tilt regulating protrusions 31 has a structure in which the outer walls 30A, 30B are bulged into the angle member insertion hole 23, and from the corners of the outer walls 30A, 30B from the recess 33 of the angle member insertion hole 23. It is located at a distance. Each tilt restricting protrusion 31 extends in the vertical direction from the upper end position of the girder 21 to the first abutting wall 32. Further, the tilt regulating protrusion 31 is narrower as it goes upward (see FIG. 8). The tilt regulating protrusions 31, 31 are abutted against a pair of outer side surfaces 90 </ b> A, 90 </ b> A of the angle member 90 as a column inserted into the angle member insertion hole 23, and play a role of restricting the inclination of the angle member 90. .

  An inner surface 31N (see FIG. 4) of the bulging structure in the tilt restricting protrusion 31 is formed by a slide core (not shown) that advances and retreats in a direction intersecting the mold opening direction of a molding die (not shown) of the pallet 10. Molded. In addition, a core joint hole 31 </ b> A is formed penetratingly at a position near the lower end of the tip end surface of the tilt regulating protrusion 31 that faces the angle inner support wall 37. And the insertion hole shaping | molding core (not shown) which shape | molds the inside of the angle material insertion hole 23 among the shaping | molding dies of the pallet 10 and the said slide core are mutually joined via the core joining hole 31A. . Further, as shown in FIG. 10, the upper end portion of the tilt regulating protrusion 31 on the surface facing the angle inner support wall 37 is a guide surface 31 </ b> S inclined so as to move away from the angle inner support wall 37 as it goes upward. ing.

  In addition, as shown in FIG. 4, the corner | angular part between outer wall 30A, 30B is rounded, and a pair of protrusion 21T, 21T is a horizontal direction in the position near the upper end in the corner | angular outer surface. It is formed in the state extended to.

  The description regarding the structure of the pallet 10 of this embodiment is above. Next, the effect of the pallet 10 will be described. When the angle member 90 as a support column is inserted into the angle member insertion holes 23 formed at the four corners of the pallet 10 of the present embodiment, the angle member 90 is guided by the guide surface 31S (see FIG. 10) of the tilt restricting protrusion 31, and FIG. As shown, a pair of inner side surfaces 90 </ b> B and 90 </ b> B in the angle member 90 is in a state of being addressed to the angle inner support wall 37. Further, in this state, the tilt regulating protrusions 31, 31 are abutted against the pair of outer side surfaces 90A, 90A of the angle member 90, and the tilt of the angle member 90 is regulated. Further, at the back of the angle member insertion hole 23, the lower end surface 90D of the angle member 90 is abutted against the first abutting wall 32 as shown in FIG. As a result, the angle members 90 are positioned in the vertical direction with respect to the pallet 10, and the upper surfaces of the four angle members 90 are flush with each other.

  Here, for example, when an angle material insertion hole having an L-shaped cross section is provided at the end of the pallet of the pallet and the angle material is sandwiched between the inner surfaces of the angle material insertion hole, the tilting is regulated. Since the insertion hole molding core for molding the inside of the angle member insertion hole in the mold becomes thin, it cannot withstand the resin pressure, and the shape can be unstable.

  On the other hand, in the pallet 10 of this embodiment, a pair of tilt restricting projections 31, 31 are provided on the inner surface of the angle member insertion hole 23, and the angle member 90 is formed by the pair of tilt restricting projections 31, 31. Therefore, the insertion hole forming core can be made thicker by widening the portion of the angle member insertion hole 23 other than the portion provided with the pair of tilt restriction protrusions 31, 31. Thereby, the pallet 10 which has the angle material insertion hole 23 can be shape | molded in the stable shape. In addition, each tilt restricting protrusion 31 is formed by causing the outer walls 30A and 30B to bulge into the angle member insertion hole 23, and forms the inside of the angle member insertion hole 23 and the slide core for forming the inner surface of the bulge structure. Since the insertion hole molding core is joined via the core joint hole 31A at the tip of the tilt restricting protrusion 31, it is ensured that the slide core and the insertion hole molding core reinforce each other and are deformed by the resin pressure. Can be prevented.

  When the angle members 90 are attached to the four corners of the pallet 10, another pallet 10 can be placed on the angle member 90 as shown in FIG. Then, as shown in FIG. 11, the upper end surface 90 </ b> C of each angle member 90 is in a state of being abutted against the second abutting walls 34 of the four corner beams 21 in the upper pallet 10. At this time, even if the angle member 90 is slightly tilted toward the center of the pallet 10, the upper end surface 90 </ b> C of the angle member 90 can be received by the L-shaped lower end wall 42 of the upper pallet 10.

  Further, the load of the load placed on each angle member 90 and the upper pallet 10 and the pallet 10 is applied to the back of the angle member insertion hole 23 in the lower pallet 10. However, in the inner part of the angle member insertion hole 23, the first butting wall 32 against which the lower end surface 90D of the angle member 90 is butted and the second butting wall 34 described above are arranged so as to be shifted vertically. Since the first and second abutting walls 32 and 34 are reinforced by the step wall 33S between the second abutting wall 32 and the second abutting wall 32, 34, the angle material insertion hole 23 is pierced by the angle material 90. Such a situation can be prevented.

  As described above, according to the pallet 10 of the present embodiment, the support column is composed of only the angle member 90 having a predetermined length, and the support member (that is, the support member) is inserted into the pallet 10 only by inserting the angle member 90 into the angle member insertion hole 23. The angle member 90) can be attached. Thereby, the protrusion part of the support | pillar to the side from the pallet 10 used as a problem conventionally can be eliminated. Further, since the upper surface opening 23K of the angle member insertion hole 23 has an L shape that is open along the upper surface corner of the deck board 11, the corner of the angle member 90 and the corner of the deck board 11 coincide with each other. This can reduce the dead space caused by the strut that has been a problem in the past. In the present embodiment, the four struts are made of only the angle member 90 having a predetermined length, so that it can be manufactured at a low cost and, when not in use, another angle member is provided at the inner corner of the angle member 90. By stacking and bundling the outer corners of 90, for example, it is possible to collect in a compact manner as compared to a case where pipe materials as a support are collected. Furthermore, since the angle member 90 of the present embodiment is made of resin, it is lighter than metal and can be easily transported.

[Second Embodiment]
This embodiment is shown in FIG. 12, and is different from the first embodiment only in that the tilt restricting protrusion 31V is formed from the upper end surface to the lower end portion of the beam portion 21V. According to the configuration of the present embodiment, the reinforcing effect of the girder portion 21V by the tilt restricting protrusion 31V is increased, and the angle member 90 can be smoothly inserted into the angle member insertion hole 23. In the present embodiment, the configuration other than the tilt restricting protrusion 31V is the same as that of the first embodiment, and therefore, the same reference numerals as those of the first embodiment are given and the duplicate description is omitted.

[Third Embodiment]
The girder portions 21W provided at the four corners of the pallet of this embodiment are shown in FIGS. 13 and 14, and the structure of the angle inner support wall 37W is mainly different from that of the first embodiment. That is, the angle inner support wall 37 of the first embodiment has a structure in which the flat plate walls 37A and 37B are connected by a chamfered wall 37C inclined at an angle of 45 degrees with respect to them (FIG. 5). As shown in FIG. 14, the angle inner support wall 37W of the present embodiment has a structure in which end portions of the two flat plate walls 37A and 37B that are close to each other are bent at right angles to the inside so as to be orthogonal to each other. ing. Further, the intersecting portions of the bent end portions 37D and 37D that are bent at right angles in both the flat plate walls 37A and 37B are connected to the diagonal wall 35. As a result, as shown in FIG. 13, the upper surface opening 23L in the angle member insertion hole 23W has an L shape with the central corner bulging inward. Further, as shown in FIG. 14, the L-shaped lower end wall 42W that closes the lower ends of the column adjacent rooms 24W, 24 has an L shape with a central corner recessed from the outside.

  Further, inside the angle member insertion hole 23W, diagonal ribs 31T project inwardly on the inner surface of the corner portion where the outer walls 30A and 30B intersect, so that the corner portion is divided into two equal parts. When the angle member 90 is inserted into the angle member insertion hole 23 </ b> W, the diagonal rib 31 </ b> T is abutted against the corner portion of the angle member 90. In addition, since structures other than the site | part mentioned above of this embodiment are the same as that of 1st or 2nd embodiment, the same code | symbol as 1st and 2nd embodiment is attached | subjected and duplication description is abbreviate | omitted.

  According to the configuration of the present embodiment, the bending end portions 37D and 37D reinforce the flat plate walls 37A and 37B, and the diagonal wall 35 reinforces the right-angle bending end portions 37D and 37D. The strength of the part to receive is increased. Furthermore, the strength of the outer walls 30A, 30B can be increased by the diagonal ribs 31T.
