Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a free-standing casing, and particularly to the structure of a casing for storing electronic/communication equipment, etc.

In recent years, equipment has become smaller and lighter in the field of electronic and communication equipment. On the other hand, various methods have been used to improve the structure of the casings used to house these devices in order to avoid wasting the mounting space inside the casings, that is, to increase mounting efficiency. There is. Improvements to this housing structure tend to be biased toward improving the mounting efficiency in the horizontal direction, but in order to further increase the mounting efficiency, it is necessary to improve the details not only in the horizontal direction but also in the vertical direction at the same time. It is desirable to make improvements.

[Problems to be solved by the prior art and the invention]

FIG. 1 is a partial view of a conventional free-standing casing, and is a front view of the lower front side with the front cover removed.
2 is a plan view seen from the direction of arrow A in FIG. 1. In both figures, numeral 10 is the floor surface, 11
12 indicates a pedestal, 12 indicates a bottom plate of the casing, 13 indicates a channel-shaped reinforcing metal fitting, 14 indicates a support member, and 15 indicates a right side cover. As shown in the figure, since the pedestal 11 and the support member 14 are attached horizontally apart from each other, it is necessary to provide strength to the bottom plate 12 itself. For this reason, the bottom plate 12 is reinforced by bending the end 12a of the bottom plate 12 or by fixing reinforcing metal fittings 13 to the lower surface of the bottom plate 12. and,
The base foot 11 is screwed to this reinforcing metal fitting 13 and fixed by a lock nut 16. Therefore, the bottom plate 12 substantially occupies a space having a dimension H in the vertical direction. Therefore, this conventional casing structure has a drawback in that the mounting space inside the casing is narrowed in the vertical direction by this dimension H space. Furthermore, since the reinforcing metal fitting 13 is required, it takes time and effort to manufacture and install the reinforcing metal fitting 13, and the weight of the casing increases.

On the other hand, in Japanese Utility Model Application Publication No. 56-172990, a horizontal frame made of square pipes is installed horizontally along the lower edge of the front and rear and left and right side walls of a housing whose lower end is open, and this horizontal frame is mounted on the installation floor. A housing structure is disclosed in which the horizontal frame is provided with means for directly or indirectly fixing it to the installation floor, and a threaded rod for level adjustment is attached so as to be movable up and down.

However, in this type of housing structure,
Because the horizontal frame made of square pipes extends horizontally along all four sides along the lower edge of the housing, the space for installing equipment at the bottom of the housing is narrowed both vertically and horizontally. A problem arises.

Therefore, the present invention can expand the mounting space inside the casing by minimizing the horizontal and vertical exclusive space of the bottom plate of the casing, and is compact and lightweight, making assembly work easier. The purpose of this invention is to provide a self-standing casing with excellent performance.

[Means to solve the problem]

The self-standing casing according to the present invention has bent parts to serve as supports on both sides of the first side cover, which are bent and integrally formed, and a flat bottom plate below the first side cover, which is L-shaped when viewed from the front. the first side cover and the upper surface of the support are connected with a ceiling plate; A casing body is formed by attaching a second side cover, a rear cover, and a front cover to the openings on three sides so as to be openable and closable, respectively.The height of the main body of the casing is adjustable and supports the base on the floor. The structure is such that the weight of the casing body housing the device therein is directly transmitted and supported by the support to the pedestal.

[Effect]

According to the structure of the autonomous housing according to the present invention, by integrating the bottom plate and the first side cover, the first side cover of the bottom plate is integrated.
Since the side cover side of the
There is no need to provide a frame extending in the front-rear direction on the edge of the side cover. Therefore, it is possible to achieve a reduction in the number of parts, a reduction in weight, and an increase in the space for installing equipment within the housing.

In addition, since the front and rear bent portions integrated with the first side cover serve as supports for supporting the ceiling board, there is no need to provide a separate support on the side of the first side cover, reducing the number of parts and Improved assembly workability can be achieved.

Furthermore, since the foot on the side of the second side cover passes through the bottom plate and is attached to the lower end of the column, the load applied to the column is directly transmitted to the foot on the side of the second side cover, and the load on the column is increased. It is possible to prevent distortion or the like from occurring in the bottom plate due to the applied load. Therefore, there is no need to bend the edge of the bottom plate on the side of the second side cover for reinforcement or to provide a horizontal frame extending in the front-rear direction. It is possible to prevent a decrease in the equipment mounting space within the housing and an increase in the size of the housing.
