DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a box-shaped structure in which a metal plate is formed in a box shape, and more particularly to a box-shaped structure constituting an outer box of a vending machine.

[0002]

2. Description of the Related Art Hitherto, a box-shaped structure in which a metal plate is formed in a box shape has been widely used as, for example, an outer box of a vending machine. Such box-like structure that constitutes the outer box of the automatic vending machine is generally is composed of a box body, provided at the bottom of the box body and the base portion. Since this base portion functions as a load receiving portion of the box body, considerable compressive strength and rigidity are required.

[0003] However, the base portion is made of a steel plate which is thicker than the box body, but it is often difficult to obtain sufficient strength by simply using a steel plate. For this reason, a countermeasure as shown in FIG. 8 is taken as a general reinforcing measure.
In FIG. 8, reference numeral 41 denotes a box body.
A base 42 is provided at the bottom of the base. Base 42
Is substantially composed of a steel plate 43 and a reinforcing member 44. That is, the reinforcing member 44 is attached to an end of the lower surface of the steel plate 43 or the like.
The base portion 42 is strengthened by improving the compressive strength and rigidity of the steel plate 43. A hole 45 is formed in the base portion 42, a leveling nut 46 is provided in the hole 45, and a leveling screw 47 is screwed into the leveling nut 46. Then, by moving the leveling screw 47 up and down according to the height difference of the installation surface 48 (for example, the ground or floor) on which the vending machine is installed, the levelness and stability at the time of installation can be improved. ing.

[0004]

However, in the above-described method, after the steel plate 43 is processed (notched, bent, drawn, etc.), the reinforcing member 44 needs to be fixed to some places by welding or the like. Therefore, the number of components of the base portion 42 is increased, and the workability at the time of manufacturing is reduced, which causes a cost increase. Further, even if the above-described reinforcement measures are taken, when the load of the box body 41 is large, or when the height difference of the installation surface 48 is large, an excessive load is applied to the steel plate 43, which causes the deformation of the steel plate 43 and the like. There is also a risk.

Further, even when the base is installed in a poor environment (for example, high temperature and high humidity) outdoors, it is necessary to apply a special surface treatment to the base 42 in order to obtain sufficient corrosion resistance and weather resistance. There was also.

[0006] The present invention focuses on the above problems,
In addition to improving the compressive strength, rigidity, corrosion resistance, and weather resistance of the base, reducing the number of parts (particularly for the machine room
It is an object of the present invention to provide a box-shaped structure for a vending machine capable of eliminating complicated processing operations and greatly reducing costs. Furthermore, the present invention aims that the vending machine is also encountered earthquake or the like, to provide a vending machine which hardly fallen to lower the center of gravity of the vending machine.

[0007]

SUMMARY OF THE INVENTION In accordance with the present invention, there is provided
Vending machine box-like structure is self-forming a metal plate into a box-shaped
An outer box of a vending machine and a concrete provided at the bottom of the outer box.
A box-shaped structure having a base portion made of
The base portion is in contact with the bottom plate portion and the bottom plate portion on the bottom plate portion.
The bottom plate and the U-shaped section
To form a machine room .

In this box-shaped structure for a vending machine,
Preferably, the base is made of reinforced concrete.
No.

Further , a ventilation port is formed in the machine room.
Preferably, an opening is provided.

[0010]

In the box-shaped structure for a vending machine as described above, since the portion substantially constituting the base of the box-shaped structure is made of concrete, it is made of a conventional steel plate. In particular, the compression strength and rigidity can be significantly improved as compared with the base portion, and the strength of the base portion can be improved to eliminate the possibility of deformation or the like. Further, by making the base portion a concrete, sufficient corrosion resistance and weather resistance can be imparted without performing a special surface treatment.

In addition, since the base portion is made of concrete, the base portion can be formed as a single piece in a single step, so that the number of parts can be reduced and complicated processing steps such as sheet metal processing can be performed. Omission is possible, and cost reduction can be achieved. Also, when using concrete,
Even if the base has a complicated shape, it can be easily formed into a desired shape, and a desired machine room can be easily formed.

Further, the base is made of concrete .
Thus, it is possible to increase only the weight of the base provided on the bottom without changing the weight of the main body of the box-shaped structure. Therefore, the center of gravity of the box-shaped structure can be set low, so that the stability after installation can be improved.

Further, by using reinforced concrete as the concrete, various characteristics required for the base portion, that is, the compressive strength, rigidity and the like can be more effectively improved.
