DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double-sided shared pallet which can be used on both front and back sides when carrying a load using, for example, a forklift.

[0002]

2. Description of the Related Art Conventionally, as a pallet for receiving goods on both sides, a pallet integrally formed of a pair of upper and lower synthetic resin materials or metal materials having the same shape and the same size has been proposed. For example, Japanese Patent Laid-Open No. 4-102551,

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and to provide the following on a lower surface of a square flat substrate.
A plurality of circular projections in plan view having the same depth dimension are formed at regular intervals in the vertical and horizontal directions, and the depth of the projections is set at a position between the plurality of circular projections in plan view. A pair of pallets each integrally formed with at least two or more concentric concave-convex ribs having a dimension substantially smaller than the dimension, and joining the bottom surfaces of the projecting portions of the pair of pallets to each other. It is characterized by being integrated.

Further, in the embodiment of the pallet alone in the dual-sided shared pallet of the present invention, the number of the plurality of circular projections in plan view formed at regular intervals in the vertical and horizontal directions is nine, and the projections are concentric in plan view. The number of the uneven ribs is four.

Further, in the embodiment of the pallet alone in the double-sided shared pallet of the present invention, the maximum diameter of each concentric concave and convex rib in plan view is substantially larger than the diameter of each circular projection in plan view. It is characterized by.

Further, in the embodiment of the pallet alone in the double-sided shared pallet of the present invention, the periphery of the rectangular flat substrate is bent toward the protruding portion.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION As described above, the double-sided shared receiving pallet of the present invention has a large number of circular projections having the same depth dimension on the lower surface of a rectangular flat substrate at equal intervals in the vertical and horizontal directions. At a position between a plurality of the plurality of circular projections in a plan view, concentric concave and convex ribs having at least two dimensions substantially smaller than the depth dimension of the projections are formed in alignment. It has a pair of pallets formed integrally. The bottom surfaces of the projecting portions of the pair of pallets alone are joined together and integrated. In the pallet alone, the number of the circular projections in plan view is nine, and the number of concentric concave and convex ribs in plan view is four. In the pallet alone, the maximum diameter of each concentric concave and convex rib in plan view is substantially larger than the diameter of each circular projection in plan view. In the pallet alone, the periphery of the rectangular flat substrate is bent toward the protruding portion.

FIG. 1 is a plan view showing an embodiment of a pallet alone used in a pallet for double-sided shared receiving according to the present invention, and FIG. 2 is a sectional view taken along line AA in FIG. It is. FIG. 3 is a plan view showing a preferred embodiment of a pallet for receiving double-sided shared goods according to the present invention, and FIG. 4 is a BB view of FIG.
FIG. 5 is a partially enlarged sectional view taken along line CC of FIG. 3.

Hereinafter, an embodiment of a pallet for double-sided receiving cargo according to the present invention will be described in detail with reference to the drawings.
1 to 5, reference numeral 10 denotes a single pallet used for the double-sided shared pallet according to the present invention, which is configured as follows. In the figure, reference numeral 1 denotes a rectangular flat substrate made of a metal plate such as a steel plate or a hard synthetic resin plate, and nine circular projections having the same depth t1 on the lower surface of the rectangular flat substrate 1 having the same depth dimension t1. 2
It is formed so as to be aligned at equal intervals in the vertical and horizontal directions. 9 above
Four concentric concave-convex ribs 3 in plan view having a dimension t2 that is substantially shallower than the depth dimension t1 of the projection 2 are integrally formed at positions between the plurality of the projections 2 in plan view. It is.

The maximum diameter φ2 of each concentric concave-convex rib 3 in plan view is substantially larger than the diameter φ1 of each circular protrusion 2 in plan view. The pallet unit 10
In the above, since the bent portion 4 bent toward the protruding portion 2 is formed at the peripheral edge of the rectangular flat substrate 1, it is possible to prevent danger to the operator.

The bottom surfaces of the projecting portions 2 of the pair of pallets 10 constructed as described above are joined to each other by, for example, spot welding, an adhesive, a rivet, a clinch (caulking), etc. to be integrated into the present invention. Such a dual-sided shared pallet is formed.

According to the pallet for double-sided use of the present invention configured as described above, it is possible to prevent torsion even when a certain load is applied, and to prevent occurrence of distortion. In addition, uniform strength can be obtained. Further, for example, when carrying a load using a forklift, the load can be used on both front and back surfaces, and the work efficiency is improved.

The one shown in FIG. 1 has nine circular projections 2 in plan view and four concavo-convex ribs 3 in concentric circles in plan view. Of course, it can be changed to any required number.

[0015]

According to the present invention, on the lower surface of a rectangular flat substrate, a plurality of circular projections having the same depth are formed at regular intervals in the vertical and horizontal directions. A pair of pallets each integrally formed with at least two or more concentric concave-convex ribs having a dimension substantially smaller than the depth of the projection at positions between the plurality of projections; However, since the bottom surfaces of the projecting portions of the pair of pallets are joined to each other and integrated, the structure is simple, the whole pallet is robust, and the cost is low. Even when a load is applied to the square flat substrate, it can prevent torsion, prevent the occurrence of distortion, and can be made lightweight and have uniform strength. Without front and back also becomes available on either side, it has an effect such as improving the work efficiency. Further, since a bent portion bent toward the protruding portion is formed at the peripheral edge of the rectangular flat substrate, there is also an effect of preventing danger to an operator.
