Abstract

(57) [Abstract] [Purpose] The base plate portion 1 serving as a loading platform has high strength, is lightweight, and has a configuration that can be manufactured at low cost while suppressing material costs.
To provide a low-cost, low-cost carrier truck. [Structure] A core plate body 5 made of paper or aluminum in which a large number of partition parts 4 are arranged side by side by a large number of partition walls 4'standing in a plan view is covered with metal thin plates 6 and 6 in contact with each other. A carriage that constitutes the base plate part 1.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a carriage.

[0002]

[Problems to be solved by conventional techniques and devices]

 If the base plate, which is the cargo bed, is made of a simple thick iron plate, the bearing strength will be sufficient, but the weight will be large and the carriage will be difficult to handle.

[0003] Thus, various proposals have been conventionally made in which the base plate portion is formed of a synthetic resin plate. However, in order to increase the strength, it is necessary to make it thicker or to provide a reinforcing material, which makes the production difficult. In addition, there is a drawback that the cost of materials and production is high and it is not possible to provide inexpensive products.

The present invention solves such a drawback, and has a structure in which a base plate portion serving as a cargo bed has high strength, is lightweight, and can be manufactured at a low cost while suppressing a material cost. Providing products is a technical challenge.

[0005]

[Means for Solving the Problems]

 The gist of the present invention will be described with reference to the accompanying drawings.

[0006] In a carrier truck in which wheels 2 are attached to the back side of a base plate portion 1 serving as a loading platform and a grip portion 3 is attached to the base plate portion 1, a large number of partition walls 4'stand upright when viewed from above. According to a carrier truck, characterized in that the base plate portion 1 is constructed by abutting and covering metal thin plates 6 and 6 on the upper and lower surfaces of a core plate body 5 made of paper or aluminum in which the partition parts 4 are arranged in parallel. It is a thing.

[0007]

[Action]

 The core plate 5 is made of paper or aluminum in which a large number of partition walls 4'are arranged side by side by a large number of partition walls 4 ', and it is easy to receive a force from the left-right direction (horizontal direction). The partition 4 deforms and expands and contracts, but has bearing strength against the force from the vertical direction.

Therefore, since the metal thin plates 6 and 6 are contact-covered on the upper and lower surfaces of the core plate 5 to form the base plate 1 having a three-body polymerized structure, the load is placed on the upper metal thin plate 6. Even if it is mounted, it has a bearing strength, and the bending of the thin metal plate 6 between the wheels 2 is suppressed by the bearing strength of the core plate body 5.

[0009]

【Example】

 In this embodiment, the material cost is reduced, and a flat plate-like core plate body 5 having a thickness of a few cm is interposed between flat metal thin plates 6 having a thickness of a few mm and which can be obtained at a low price. It constitutes the body 1.

In this embodiment, not only the upper and lower surfaces of the core plate 5 but also the entire six surfaces are covered with the thin metal plates 6.

The core plate body 5 is made of paper in which a large number of honeycomb-shaped partition parts 4 are arranged side by side by a large number of partition walls 4 ′ when seen in a plan view.

The core plate 5 may be made of aluminum, and it is desirable that the core plate 5 be inexpensive and lightweight.

The vertical bearing strength of the honeycomb core plate 5 increases as the thickness of the partition wall 4 ′ increases and the density of the partition portions 4 increases.

[0014]

[Effect of the device]

 Since the present invention is configured as described above, the necessary members that make up the base plate are a thin metal plate that is inexpensive and easily available, and a large number of partition parts when viewed from the plane of paper or aluminum. Since it is a core plate that has a core plate, it can be manufactured at an extremely low cost and is lightweight, and since the thin metal plates are arranged on both upper and lower surfaces of this core plate, it is easy to manufacture, so it is a very inexpensive carrier truck. Can be provided.

Further, since the core plate body has no strength in the horizontal direction, which is unrelated to the load bearing, but has a sufficient vertical bearing strength, it has a strong load bearing strength. It becomes a dolly.

Further, since the core plate is covered with the thin metal plate, it is a carrier truck that is not easily damaged and has excellent durability.
