Description

[Detailed description of the invention] [Industrial applications]

 The present invention relates to a pallet used when carrying a load using a forklift or the like, and particularly relates to a pallet body having improved durability.

[0002]

[Prior art]

 Conventional pallets for forklifts include a stack of wooden, plastic or corrugated cardboard bars or a stacking plate with a single plate, and a plurality of girder members fixed to the underside of the stacking plate with an interval. Are provided.

[0003] Wooden or plastic pallets have the disadvantage that they are heavy and therefore expensive to transport, especially when transported abroad, and take up a lot of space when not in use and when stacked at the time of collection. . Overseas, the use of nails is restricted by laws and regulations, and plates and nails must be separated and discarded, which requires time and effort. In addition, on wooden pallets, the wood is apt to absorb moisture, so it can easily get stuck and break and lose its strength. In order to do so, it is necessary to carry out a smoking process, which is troublesome and costly.

[0004]

[Problems to be solved by the invention]

 In order to solve these problems, cardboard, which is a lightweight material, has been frequently used. However, in the case of cardboard, it is difficult to use it repeatedly because it is inferior in durability to wood and plastic, and it tends to have insufficient strength when working with forklifts. In fact, it is inferior to conventional materials and has not been completely replaced.

[0005]

[Means for Solving the Problems]

 An object of the present invention is to overcome the insufficient strength of cardboard, to enable repeated use, and to provide a pallet that can be collected without being bulky after being transported. Therefore, in the present invention, the durability of the cardboard pallet is improved by attaching a steel frame to the outer periphery of the cardboard pallet body.

[0006] A plurality of girder members are arranged in parallel or in a grid at predetermined intervals, and a cardboard pallet body provided with a loading plate on the upper surface of each of the girder members. An insertion hole for a fork is formed, and the fork is surrounded by a steel frame including a first frame provided on the upper surface of the upper stacking plate and a second frame provided on the lower beam member.

The first frame has a frame portion along an outer periphery of the loading plate and a wall rising from an outer edge of the frame portion, and the second frame has an outer portion of a beam on a lower surface of the beam. It has a frame portion along the circumference and an engagement piece that is bent inward from the lower end of the frame portion and includes each of the beam members, and the first frame and the second frame are connected by a connecting member. ing. The connecting member is provided with a reinforcing piece that extends inward of the pallet body and is provided on a top surface of the fork insertion hole.

[0008] The outer width of the second frame is set smaller than the inner width of the first frame. This allows the bottom of a pallet to be stacked on top of another pallet, which is stable during collection and can be transported in a small amount of space, while preventing lateral movement and preventing transport. An easy effect is obtained. Since the first frame and the second frame guard the top and bottom surfaces of the pallet body, corners and edges that are easily damaged are reinforced.

[0009]

[Embodiment of the invention]

 Next, embodiments of the invention will be described with reference to examples. FIG. 1 is an exploded perspective view showing the entire configuration of the embodiment. The pallet includes a pallet main body 3, a first frame 1 disposed on the upper part of the pallet main body 3, and a second frame 2 disposed on the lower part of the pallet main body 3. The pallet body 3 is composed of a girder member 32 arranged in a lattice and a loading plate 31 arranged on the upper surface of the girder member 32. Two notches 33 are formed on the left and right sides of the girder member 32 so as to correspond to insertion of a forklift fork.

FIG. 2 is a perspective view of the pallet body 3 as viewed from the bottom. As shown in FIG. 3, the cardboard girder 32 is assembled by engaging the engagement grooves 34a and 34b of the girder 32a and the girder 32b, which are installed in the vertical and horizontal directions, with each other. To form a pallet body 3.

In FIG. 1, a first frame 1 provided on the upper surface of a pallet body has a frame portion 11 made of steel and having an outer dimension slightly larger than a loading plate 31, and a wall rising from an outer edge of the frame portion 11. A part 12 is formed. The second frame 2 disposed on the bottom surface of the pallet body 3 is also made of steel and has a lower end bent inward to engage with the bottom surface of the pallet body and an outer edge of the frame portion 21. And has a wall 22 that encloses the outer periphery of each girder. Notch portions 23 are formed in the opposing wall portions 22 corresponding to the fork insertion holes formed in the beam members of the pallet body 3.

The first frame 1 and the second frame 2 are fixed by a connecting member 4. A reinforcing piece 41 is formed in the connecting member 4 so as to extend inward and abuts against the girder in the notch 33 of the girder outside the pallet body 3 to reinforce the top surface of the fork insertion hole. . FIG. 4 is a perspective view of a pallet to which the first frame 1 and the second frame 2 are attached. Here, in order to increase the connection strength, in addition to the connection member 4, H-shaped connection members are provided at the corners and at the ends, respectively. By using a plurality of connecting members in this way, it is possible to achieve weight reduction while maintaining a predetermined connecting strength.

[0013]

[Effect of the invention]

 The present embodiment is configured as described above, and the top and bottom surfaces of the pallet body made of cardboard are guarded by the frame portions of the first frame and the second frame, and the side surfaces of the pallet body are respectively protected. Since the frame wall and the connecting member guard, the strength of the pallet corners and edges that are easily damaged is improved.

In addition, the reinforcing piece 41 of the connecting member 4 fixed and integrated with the first frame 1 and the second frame 2 abuts on the girder member within the notch of the girder member inserted by the fork of the forklift, Since the fork is transmitted to the girder through the reinforcing piece, the force can be distributed to the frame, and the fork can be prevented from hitting the girder and damaging the girder.

In addition, by setting the outer width of the second frame to be smaller than the inner width of the first frame, when a plurality of pallets are conveyed or collected, the bottom of the pallet is overlapped with the top of another pallet. It can be carried out. As a result, it is possible to convey in a small space, and the movement in the lateral direction is prevented, so that an effect of easy conveyance can be obtained.
