  FIG. 5 shows an example of a metal pallet in which a reinforcing cover according to the present invention is attached to a pedestal. The illustrated pallet P uses a long leg frame member 10 and a top plate member 11 made of steel, and is arranged on three leg frame members 10 arranged in parallel to each other in a direction perpendicular to them. Five top plates 11 are fixed by spot welding and assembled in a lattice shape. The leg frame member 10 has a structure in which a plurality of connecting leg posts 14 are fixed between the upper plate 12 and the lower plate 13 and an opening 15 is formed between the leg posts 14 for inserting a fork of a forklift. It has become.

  In the illustrated pallet P, the top plate member 11 and the upper plate 12 and the lower plate 13 of the leg frame member 10 are each made of a plate material that is bent and formed into a square wave shape with unevenness in the width direction, as shown in FIG. Become. In particular, the upper plate 12 and the lower plate 13 are each processed into an angular wave shape in which at least two parallel fitting longitudinal grooves 16 and 17 are formed in the length direction on both side edges in the width direction.

  In the leg frame material 10, the pedestal 14 is made of, for example, a single thin steel plate, and is bent into a short channel shape as a whole, both of which are a flat bottom plate portion 14 a and side plate portions 14 b. 14c is formed. In addition, it is bent in a small U-shape so as to face each other at the corner between the bottom plate portion 14a and the side plate portions 14b, 14c, and is bent in a small U-shape so as to face each other in the same manner at the leading edges of the side plate portions 14b, 14c. A first fitting portion 14d is provided at the corner edge of the both side plate portions 14b and 14c with the bottom plate portion 14a, and a second fitting portion 14e and 14e is provided outwardly at the tip edge. The first and second fitting portions 14d and 14e are processed by being bent into a U-shape having a size that allows fitting into the groove widths of the longitudinal grooves 16 and 17 in the upper plate 12 and the lower plate 13. Further, the both side plate portions 14b and 14c are bent at the upper and lower ends at right angles to form the welding rib pieces 14f and 14g, and the upper and lower end portions of the fitting portions 14d and 14e are welded. From the height position of the rib pieces 14f and 14g for use, it has a shape protruding in the vertical direction in the figure by the depth of the longitudinal grooves 16 and 17. The leg frame member 10 is provided with three pedestal pillars 14 having such a shape between the upper plate 12 and the lower plate 13 so that the side plate portions 14b and 14c are orthogonal to each other, and both fitting portions 14d and 14e are provided. Are fitted into the longitudinal grooves 16 and 17 and connected to each other and spot welded by rib pieces 14f and 14g to be fixed to the upper plate 12 and the lower plate 13 for assembly.

  Therefore, the illustrated pallet P is detachably mounted by fitting the reinforcing cover 20 of the present invention on the pedestal 14 of the leg frame material 10 described above. Therefore, the reinforcing cover 20 is made of a spring steel plate, and as shown in FIGS. 3 and 4, is bent substantially at right angles to match the two surface shapes of the bottom plate portion 14 a and the side plate portion 14 b (or 14 c) of the pedestal 14, The first reinforcing plate portion 20a is bent on the side and the second reinforcing plate portion 20b is formed on the other side, and is bent into an L plate shape. Further, the first reinforcing plate portion 20a is bent at an end at a right angle facing the second reinforcing plate portion 20b at a right angle, and further, the first reinforcing plate portion 20a is substantially aligned with the bent plate piece 21 of the second fitting portion 14e in the bent piece. At the length position, the bending tip is folded back into a V shape toward the second reinforcing plate portion 20b, and a hook portion 20c is formed there. On the other hand, the second reinforcing plate portion is bent at an end at a right angle facing the first reinforcing plate portion 20a at a right angle, and the width of the second reinforcing plate portion is matched to the bent plate piece 22 of the first fitting portion 14d in the bent piece. At the position, the bent tip is bent in a left-right inverted shape so as to be convex toward the first reinforcing plate portion 20a, and the fitting portion 20d and the pressing portion 20e are connected to the bent piece. To be molded.

  As shown in FIG. 1, the reinforcing cover 20 having such a shape has a hook portion 20 c and a bent plate of one of the second fitting portions 14 e and 14 e in the pedestal column 14 as shown in FIG. 1. Hooked on the piece 21, the two reinforcing plate portions 20a and 20b are applied to the side plate portion 14b (or 14c) and the bottom plate portion 14a against the spring property, and the fitting portion 20d of the second reinforcing plate portion 20b is made spring property. The pressing portion 20e is elastically pressed against the plate surface of the side plate portion 14c (or 14b) while being fitted to the leg column 14 while being fitted to the U-shaped convex portion of the first fitting portion 14d. Then, the reinforcing cover 20 is attached to the pedestal 14 in a state where both the reinforcing plate portions 20a and 20b are embraced with the side plate portion 14b (or 14c) and the bottom plate portion 14a based on the spring property. Then, in the pallet P, the reinforcing cover 20 attached to the pedestal 14, as illustrated in FIG. It is covered and protected by the plate portions 20a and 20b.

  Therefore, even when the pallet P shown in the figure is used and the fork of the forklift collides with the leg column 14 by mistake, the leg column 14 attaches the bottom plate portion 14a and the side plate portion 14b (or 14c) to the reinforcing cover 20. Since the reinforcing plate portions 20a and 20b are overlapped and reinforced, the impact force applied to the inner leg column 14 is weakened to prevent the leg column 14 from buckling or being damaged. In addition, the vertical load received from the load placed on the top plate 11 is supported by the pedestal 14 and the reinforcing cover 20, and the pedestal 14 buckles in the same manner even if the load is heavy. To prevent damage.

  On the other hand, when the reinforcing cover 20 is removed from the pedestal 14 as necessary, the pressing portion 20e is pushed up against the spring property to remove the pressing against the side plate portion 14c (or 14b), and both the reinforcing plate portions 20a. The hook portion 20c may be removed from the second fitting portion 14e while being detached from the side plate portion 14b (or 14c) and the bottom plate portion 14a so as to peel off 20b.

  By the way, the reinforcing cover 20 according to the present invention may be provided with an identification means for identifying a load placed on the top plate 11 when the pallet is used. For example, the identification means has a configuration in which the reinforcing cover 20 is formed of colored steel plates having different colors. Then, according to the internal luggage placed on the top plate 11, for example, packed in a cardboard box, the corresponding color reinforcement cover 20 is selected and attached to the pedestal 14, and the difference in color of the reinforcement cover 20 A package placed on the top plate 11 is identified. Therefore, according to the present invention, the reinforcing cover 20 of the corresponding color can be appropriately attached to and detached from the pedestal 14 in accordance with the load placed on the top plate 11. In the present invention, the identification means may be configured by imprinting or printing appropriate marks on the reinforcing plate portions 20a and 20b of the reinforcing cover 20. Further, the identification means can be configured by attaching a seal to the reinforcing plate portions 20a and 20b.

  The reinforcing cover 20 of the illustrated embodiment described above has shown an example in which the hook portion 20c is bent into a V shape and the pressing portion 20e is bent into a dogleg shape, but is not limited to the illustrated example, As long as it can be hooked on a part plate piece of the second fitting portion 14e of the pedestal 14, it may be another hook shape such as a U shape, and the pressing portion is also a plate of the side plate portion 14c (or 14b), for example. If it can be pressed against the surface, it may be formed in a convex shape such as a U shape or a U shape.

  As shown in FIG. 6, for example, the reinforcing cover 20 of the present invention has a plate structure in which both reinforcing plate portions 20a and 20b are partially shaped into a fine wave shape to increase rigidity. It is possible to increase the rigidity by increasing the rigidity against a vertical load received from a fork collision or a loaded load.
