Description

Prefabricated Pallet {The pallette in kit form}

The present invention relates to a prefabricated pallet, and more specifically, when assembling a prefabricated pallet that can be assembled and disassembled in a grid using a plurality of horizontal members and vertical members, orthogonal to the horizontal members of any one of the plurality of horizontal members. It relates to a prefabricated pallet so that the assembly and disassembly of the pallet can be made easily by fixing the coupling pins coupled to each of the plurality of vertical members at the same time with one coupling rod.

In general, a pallet that serves as a mobile pedestal that can be transported and stored together with parts is widely used in a production site or a product storage warehouse for various products to simplify the storage and transport of various items.

The pallet is a two-stage structure in which an upper pedestal in which an article is placed on a lower pedestal placed on a floor is combined. The pallet is carried by putting a conveying mechanism between the upper and lower pedestals, mainly wood, metal or It is made of a synthetic resin material, and the items to be loaded on these pallets are generally shaped to be easily stacked and stacked in multiple layers, such as hexahedral and columnar.

Among the pallets made of various materials in order to facilitate the transport and storage of goods as described above, wooden pallets have been used for a long time since they are relatively inexpensive, but they are easy to be damaged and have a low number of repeated use. As a result, industrial policies in each country are shifting to curb or prohibit the use of wooden pallets.

In order to supplement the disadvantages of wood pallets, which are not only repetitive in use, but also undesirable in terms of forest protection, upper and lower one-piece synthetic resin pallets have been developed. It is not only easy for the worker to handle, but also has a problem that the cost of recovering it is increased because the weight and volume is larger than the wooden pallet.

Therefore, in order to solve the problems of the integral synthetic resin pallet as described above, a pallet that can be dismantled and assembled repeatedly has been developed. Such a prefabricated pallet can be found in Korean Registered Utility Model Publication No. 20-296881, 20-314812, etc. Has been disclosed.

However, the conventional prefabricated pallets can be disassembled and assembled into a conventional one-piece pallet, which improves efficiency in terms of recovery and transportation of the pallets. Not only is this lengthened, but also when the member of a grid | lattice metal mesh, a wire, etc. is used, there exists a tendency for the appearance quality to fall.

In addition, the conventional general pallet is a structure in which a plurality of horizontal members are coupled to be parallel to each other orthogonal to the vertical members on a plurality of vertical members arranged in parallel, a plurality of vertical members parallel to each other on the horizontal member is combined, forklift In the case of using a forklift, the fork of the transport means is transported by pushing the fork in the space between the two upper and lower vertical members spaced apart from each other, and then lifting the fork in close contact with the bottom of the upper vertical member. There is no problem in using the pallet, but when people are using a portable lift with a hand-held hydraulic system, the use of the pallet becomes very cumbersome.

In the case of the portable lift, a frame having a wheel and a fork are arranged in parallel in the front, and when the portable lift is used, unlike the forklift that pushes only the fork between the upper and lower vertical members, the frame and the fork are used. Should be pushed together between the upper and lower vertical members.

However, in the conventional lower vertical member, since the cross section of the width direction is rectangular, the wheel of the frame cannot pass over the vertical member, and the fork also cannot be pushed between the upper and lower vertical members so that the pallet can be supported by If you do not wear it, you will not be able to carry the pallet as a portable lift.

Of course, if the thickness of the lower vertical member is thin, the wheels of the portable lift frame may exceed the lower vertical member, but in this case, the rigidity of the lower vertical member may be reduced, resulting in an increase in the damage rate of the pallet due to use.

The present invention was devised to solve all the problems of the conventional prefabricated pallets, and it is possible to reduce the pallet operating cost by reducing the assembly and dismantling time of the pallets, and can be used regardless of the type of transportation means.

That is, there is a structural feature of the present invention to shorten the assembly and dismantling time of the pallet by coupling a plurality of upper and lower vertical members coupled to each horizontal member by one connecting rod.

And, as described above, in order to solve the difficulty in using a portable lift when the cross section in the width direction of the lower vertical member constituting the bottom of the pallet is rectangular, the upper surface of the lower vertical member constituting the pallet of the present invention is In the width direction, the height of the one end is gradually increased from the bottom of the bottom portion to have a maximum height in the center, and then to the other end is composed of a curved surface gradually decreases to the bottom, so that the wheel of the frame can pass over the lower vertical member of the present invention There is another structural feature.

That is, the frame wheel of the portable lift can be pushed into the space between the upper and lower vertical members by crossing the width curved surface that becomes the upper surface of the lower vertical member. It is possible to move the pallet by lifting the pallet from the ground with the frame wheels positioned on the floor between two lower longitudinal members arranged parallel to each other.
