A pallet for carrying goods, in which the pallets are arranged and fixed at predetermined intervals in a direction orthogonal to the open side of the lip, with the lip groove at the intersection of the rectangular pipe and the tip of the lip groove. It is provided with a stopper that can enter and exit from the upper surface of the material, and uses a steel square pipe for the girder material and deck material, and is lighter and relatively inexpensive compared to conventional pallets that have fixed stoppers. It has a structure that can secure the structural strength, can more easily and surely prevent collapse of the load during pallet transport, and does not hinder loading and unloading.

In the present invention, pallet components (square pipes, lip channels or reinforcements, etc.) are mainly made of steel, but are made of metal materials such as stainless steel, titanium (alloy) and aluminum (alloy). The surface may be coated with a coating having excellent anticorrosion properties, or the surface may be treated (including plating) depending on the use environment or for the purpose of extending the life. The reason for using the lip channel in the present invention is that it is lighter than a square pipe and is advantageous in terms of cost.

An embodiment of the present invention will be described below with reference to the drawings. In the following embodiments, main parts such as a square pipe, a lip channel, and a locking structure using a stopper are made of steel. The pallet for transporting goods (hereinafter, simply referred to as "pallet") of the present invention basically has, for example, three rectangular steel pipes 5a to 5c arranged in parallel at predetermined intervals as shown in the embodiment of FIG. A plurality of lip channel steels 6a to 6n are arranged on the upper surface of the rectangular steel pipe in a direction perpendicular to the rectangular steel pipe, and the outer surfaces of the lip portions rp are arranged at predetermined intervals to abut and weld. By doing so, the rectangular steel pipes 5a to 5c and the lip channel steels 6a to 6n are integrated into a shape of a cage.

FIG. 2A shows an example of the square steel pipes 5a to 5c used here. Further, the lip channel steels 6a to 6n have a C-shape as shown in FIG. 2B, and it is preferable to coat anticorrosive paint on the surfaces of all of them.

[0011] In the present invention, in such a pallet P2, the rigidity is ensured and the life is ensured by using, as the forming material, the rectangular steel pipes 5a to 5c and the lip channel steels 6a to 6n having high rigidity and relatively light weight. To extend. In addition, an empty pallet is stacked on a carrier such as a truck or a truck by providing a different locking structure with a stopper 4s that can be put in and taken out at the intersection of the square steel pipe and the end of the lip channel steel. When transporting the pallets, the pallets are prevented from being displaced from each other to prevent collapse of cargo.

The locking structure by the stopper 4s is formed at four corners here. Specifically, as shown in FIGS. 3 and 4, square steel pipes 5a and 5c forming corners and a lip are formed. The end portions of the channel steels 6a and 6n are pre-processed and can be easily formed when assembling them.

As shown in FIG. 4 (a), a rectangular steel pipe 5a is provided with a through hole 7a through which a cylindrical casing 9 made of a steel pipe is inserted in an upper wall 5e, and pallets are stacked on a lower wall 5d. The lip channel steel 6a, which is sometimes abutted and fixed to the square steel pipe 5a, is provided with a through hole 7b into which the stopper 4a of another pallet P3 located below is inserted, as shown in FIG. 4 (b). As described above, the through hole 8 for allowing the stopper 4s to enter and exit is formed in the upper wall of the distal end portion. Therefore, when the lip channel steel 6a is brought into contact with and fixed to the rectangular steel pipe 5a, the through hole 8 is drilled at a position where the center thereof substantially coincides with the through hole 7a of the upper wall 5e of the rectangular steel pipe 5a in the vertical direction. I have.

In the through hole 7a of the upper wall 5e of the rectangular steel pipe 5a, a cylindrical casing 9 is located at the upper end in the internal space of the lip channel 6a, and the lower end is in the internal space of the rectangular steel pipe 5a. And fixed by welding w. As shown in FIG. 4 (c), the cylindrical casing 9 has a vertical groove 10a in the side wall on the open end side of the rectangular steel pipe 5a, an upper fixing groove 10b bent substantially horizontally from the vertical groove, and a lower fixing groove. A U-shaped (or inverted U-shaped) groove formed by the groove 10c is provided.

Here, the rest lower limit position (retreat position) of the stopper 4s is determined by the lower end position of the vertical groove 10a. The installation of the fixing groove 10c is not indispensable, but in order to prevent the stopper 4s from freely moving in the vertical groove 10a due to the inclination and vibration during the handling of the pallet P2 and generating an unpleasant sound, the fixing groove 10c is required. It is preferable to lock the operation pin 11 at the position.

A stopper 4 s made of a steel pipe is inserted into the cylindrical casing 9 so as to be able to move up and down and rotate. This stopper has a pin hole 12 in the lower part as shown in FIG. 4D, and the stopper 12 penetrates the groove (10a or 10b) provided in the cylindrical casing 9 as shown in FIG. By inserting the operation pin 13 as shown in the figure, the operation pin 11 is moved up and down in the cylindrical casing 9 along the vertical groove 10a, and is rotated along the fixed groove 10b or 10c to thereby stop the stopper 4s. The vertical position of can be fixed.

When the operation pin 11 is locked in the lower fixing groove 10c, the upper end of the stopper 4s is located slightly lower than the upper surface of the lip channel steel 6a fixed to the upper surface of the rectangular steel pipe 5a. 11 is locked in the upper flat fixing groove 10b, the length of the stopper 4s and the elevating stroke so that the upper end of the stopper 4s projects from the upper surface of the lip channel 6a to a predetermined height h. Is set.

Here, the operation pin 11 of the stopper 4s is moved along a U-shaped groove composed of the vertical groove 10a, the upper fixing groove 10b, and the lower fixing groove 10c. The stopper is stopped and positioned at the upper limit of the stopper 4s, and is locked in the fixing groove 10c so as to be positioned at the lower limit of the stopper 4s. However, depending on the structure of the pallet, the stacking condition, the locking position by the stopper 4s, etc. It is also effective to form a groove, for example, in an E-shape and increase the number of fixing grooves so that the protrusion height h of 4 s can be made variable.

The locking structure by the stopper 4s is formed at the corner in the above description, but is not limited to this, and the intersection between the rectangular steel pipe and the tip of the lip channel steel other than at the corner. May be formed. According to the structure (including the weight) of the pallets, the stacking conditions, and the transport conditions of trucks, etc., the locking structure may be selected in terms of the number of formed portions and the number of formed portions so as to ensure sufficient functions.

FIG. 5 shows another embodiment of the present invention. In this embodiment, in order to further secure the strength of the pallet, the reinforcing structure in which the reinforcing plate 13 is fixed to the lower surfaces of the rectangular steel pipes 5a to 5c by welding w is fixed on the pallet P2 as shown in FIG. Pallet P4. As shown in FIG. 5 (b), the reinforcing plate 13 has through holes 14 at both ends so as to expose the through holes 7b in the lower wall of the rectangular steel pipe 5a. It is the same as the main pallet that the surface may be coated with anticorrosive paint.
