Japanese Patent Laid-Open No. 10-129661 (FIGS. 1 and 2)

  In general, in a plastic pallet to which a support tool can be attached, the top plate of the support tool comes into contact with the top surface of the pallet, so that water adhering during storage in the freezer warehouse is frozen and the support tool is attached to the pallet. There are problems that it becomes difficult to remove from the pallet, and that melted water wets the cargo loaded on the pallet.

  In order to solve these problems, it has been proposed that the pallet described in Japanese Patent Laid-Open No. 10-129661 forms an inclined surface that is inclined toward the groove side into which the fixing plate is fitted. However, since the inclined surface is formed only on the groove side, it is not enough to prevent freezing and flow of melted water, and the melted water enters the fitting hole and wets the cargo loaded on the lower pallet There's a problem.

  Therefore, it is intended to provide a synthetic resin pallet in which water adhering to the pallet is prevented from freezing and sticking the support to the pallet, and the melted water flows down to the side surface of the pallet.

  The synthetic resin pallet according to the present invention has the following configuration in order to achieve the above object. That is, in the synthetic resin pallet according to the present invention, the top plate is disposed between the upper portions of the second side plates orthogonal to the first side plate, and the fixing plate orthogonal to the first side plate and parallel to the second side plate is used as the top plate. The first side plate side of the fixed plate is cut out, an engagement piece is formed on the opposite side of the first side plate side, and a support column is provided above the top plate. A synthetic resin pallet to which a support tool can be attached, wherein a support tool mounting portion is formed at a corner portion of the pallet, and the support tool mounting portion has an engagement piece fitted in a concave surface formed at the corner portion. A projecting piece on which the insertion hole and the top plate are placed is projected, and two orthogonal end surfaces of the concave surface are formed to open to the side surface of the pallet. The concave surface is preferably formed in an inclined surface inclined downward toward the side surface of the pallet. Moreover, it is preferable that the number of projecting pieces is two or more and the upper surface is formed in a curved surface. Moreover, the upper surface height of the protruding piece can be formed lower than the upper surface of the upper deck board.

  A synthetic resin pallet according to the present invention will be described in detail based on the illustrated embodiment. Before describing the embodiment of the present invention, the structure of a support metal fitting that can be detachably attached will be schematically described.

  FIG. 1 is a perspective view showing an example of a support tool, and includes a support tool main body 1 and a column 6 fixed integrally to the support tool main body 1. The support body 1 includes a top plate 4 disposed between the first side plate 2 and the second side plate 3 orthogonal to the first side plate 2, and is orthogonal to the first side plate 2 and parallel to the second side plate 3. The fixing plate 5 is projected downward at the end of the top plate 4, the notch 5 a is provided at the lower end of the fixing plate 5 on the first side plate 2 side, the upper portion of the notch 5 a is used as a locking piece 5 b, An engagement piece 5 c is formed on the opposite side to the first side plate 2. A substantially L-shaped support column 6 is projected above the top plate 4.

  The support column 6 protrudes from the top surface of the top plate 4. However, the support plate may be formed by extending the first side plate 2 and the second side plate 3 as they are. In this case, the top plate 4 may be disposed inside the first side plate 2 and the second side plate 3. Moreover, the structure of the support | pillar 6 is not limited to the said L-shaped support | pillar, A pipe-shaped support | pillar is installed upright on the top plate 4, or the pipe of the 1st side plate 2 or the 2nd side plate 3 on the corner side outer surface. The structure formed by adhering a cylindrical support may be sufficient. Further, the material of the support body and the support is preferably metal, wood, synthetic resin, or the like.

  Next, a pallet for mounting the support metal fitting body 1 will be described. As shown in FIG. 2, the pallet P is formed by connecting an upper deck board 11 and a lower deck board 12 with a girder 13, and a portion surrounded by the upper deck board 11, the lower deck board 12 and the girder 13 is a forklift. A fork insertion hole 14 is provided for inserting a fork. The upper deck board 11 and the lower deck board 12 can have a known structure, and are not particularly limited.

  A support fixture mounting portion 15 for mounting the support fixture body 1 is formed at an upper corner portion of the upper deck board 11. The support attachment portion 15 has a concave surface 16 that is substantially the same as or slightly larger than the top plate 4 in a plane at the corner portion of the upper deck board 11, and the engagement piece 5 c is inserted into the inner edge of the concave surface 16. A fitting hole 17 is formed. Further, a projecting piece 18 on which the top plate 4 is placed projects from the concave surface 16.

  In addition, when the engagement piece 5c is formed not from the end portion of the fixed plate 5 but from the central portion, the size of the concave surface 16 is the same as the top plate or slightly as in the above embodiment. It is not limited to forming large, You may form smaller than a top plate.

  The corners of the concave surface 16 are open to the side surfaces of the four corners of the pallet, and the depth of the concave surface 16 is formed to be the same as or larger than the height of the locking piece 5 b of the support body 1. Furthermore, the concave surface 16 may be a horizontal surface, but is preferably formed on an inclined surface that is inclined downward toward the side surface of the pallet in the same direction as the projecting piece 18. In this way, by forming the concave surface 16 on the inclined surface, even if the dew is melted by being heated from the freezer warehouse and the column is heated, the water flows down the side surface of the pallet along the inclined surface, so that the load is wetted. Or flow down to the upper surface of the lower pallet.

  The insertion hole 17 is provided at an inner corner of the concave surface 16 so that the engagement piece 5c is inserted when the support body 1 is attached, and is formed through the upper deck board 11 in the thickness direction. Has been. The position of the insertion hole 17 is changed corresponding to the engagement piece 5c.

  The projecting piece 18 is formed in a rectangular plane and is projected in parallel with one side surface of the pallet. The upper surface of the projecting piece 18 is flush with the upper surface of the upper deck board. If the top surface of the projecting piece 18 is formed on the same surface as the top surface of the deck board, the top plate protrudes from the top surface of the deck board. Therefore, the top plate 4 of the support body 1 may be formed as low as the wall thickness. . When the upper surface of the projecting piece 18 is formed lower than the upper surface of the upper deck board by the thickness of the top plate 4, the depth of the concave surface 16 may be formed deeper by that amount.

  The upper surface of the projecting piece 18 may be a horizontal smooth surface or a curved surface. When the upper surface of the projecting piece 18 is formed in a curved surface, the contact surface with the top plate 4 becomes smaller, and the sticking between the support body 1 and the pallet can be more effectively prevented by freezing in the freezer warehouse. .

  FIG. 5 shows a second embodiment of the support attachment portion 15, and FIG. 6 shows a third embodiment. In any embodiment, the configuration of the concave surface 16 and the insertion hole 17 in the support attachment portion 15 is the same as that in the first embodiment, and only the shape of the protruding piece 18 is different. Accordingly, the same components are denoted by the same reference numerals and the description thereof is omitted. However, unlike the first embodiment, the inclined surface of the concave surface 16 can be an inclined surface inclined downward toward the corner portion. Thus, when it is set as the inclined surface which goes to a corner part, water can flow down from a corner part. In particular, it is effective when the protruding piece is formed away from the corner portion as in the third embodiment shown in FIG.

  The projecting piece 18a of the second embodiment shown in FIG. 5 is projected from the tip of the corner portion, and the projecting piece 18b and the projecting piece 18c outer surface are projected so as to be flush with the side surface of the pallet. The projecting piece 18b is provided integrally with the upper surface of the upper deck board so as to protrude into the concave surface, but the projecting piece 18c is provided with a gap between the upper surface of the deck board. Similarly to the case of the first embodiment, the protruding height of the protruding pieces 18a to 18c may be formed lower than the upper surface of the upper deck board by the thickness of the top plate 4 of the support body 1. In this way, when the upper surfaces of the projecting pieces 18a to 18c are formed low, the upper surface of the top plate 4 and the upper surface of the upper deck board can be formed on the same surface.

  Next, the projecting pieces 18d to 18f of the third embodiment shown in FIG. 6 are projected from the side end surface of the pallet and inside the concave surface 16. The planar shapes of the projecting pieces 18d to 18e are different, the projecting piece 18d is a quadrangle, the projecting piece 18e is a trapezoid, and the projecting piece 18f is a hexagon. Further, the protruding heights of the projecting pieces 18d to 18f are set so that the top plate 4 of the support body 1 is higher than the upper surface of the upper deck board as in the case of the projecting pieces 18 and 18a to 18c, as in the first embodiment. It may be formed as low as the thickness of.

  In addition, as shown in the said embodiment, the shape, height, number, etc. of a protrusion can be determined arbitrarily and are not limited to the said embodiment. Moreover, the protrusion piece should just be what can mount the top plate 4 of the support tool main body 1 horizontally.

  In order to attach the support body 1 to the pallet having the above-described configuration, the engagement piece 15c is inserted into the insertion hole 17, and the first side plate 2 and the second side plate 3 are positioned outside the corner portion of the pallet, and the top plate 4 is placed. May be placed on the protruding piece 18. Since the locking piece 5b is inserted into the concave surface 16, the top plate 4 can be detachably attached horizontally. Since the first side plate 2 and the second side plate 3 are locked to the side surface of the pallet and the engagement piece 5c is inserted into the insertion hole 17, the support column 6 is securely attached to the pallet.
