JPS5919440Y2 - Ceiling structure of electronic device housing - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a housing housing an electronic device, such as a housing for a computer main unit, and particularly to a structure of a ceiling portion thereof.

FIG. 1 is an exploded perspective view showing the ceiling of a conventional electronic device housing.

Reference numeral 1 denotes a frame of the casing, on which a wire mesh 2 is placed and fixed.

When cooling equipment inside an enclosure, it is necessary to leave the ceiling open to allow ventilation without sealing it, but wire mesh is generally placed on the ceiling to prevent objects from falling into the equipment from above. It's covered.

A louver 3 is installed on top of the wire mesh 2 because just covering it with a wire mesh does not look good and is insufficient in terms of design.

As shown in the enlarged view of FIG. 2, the louver 3 is made up of strips assembled in a grid pattern, and is the same as those used for interior decoration.

With the four sides of this louver 3 surrounded by decorative frames 4 to 7,
It is placed on the wire mesh 2.

However, since the louver 3 is made by combining a large number of strip plates, it is very expensive, leading to an increase in the cost of the device.

Furthermore, since there are a large number of parts, the workability of assembly, painting, etc. is also poor.

The purpose of the present invention is to solve these problems, and for this purpose, the present invention does not use expensive louvers as in the past, but instead uses a wire mesh that also serves as a louver. I'm picking it up.

FIG. 3 is a perspective view showing the structure of the ceiling according to the present invention, and FIG. 4 is a partially enlarged perspective view thereof.

8 is a metal plate with countless holes made by press working, and is called a metal lath.

In the present invention, concave portions 9 and convex portions 10 are alternately machined on this metartal lath as shown in the figure, giving it a wave-like shape.

The four sides of the metal lath 8 bent into a corrugated shape are surrounded by decorative frames 11, 12, 13, and 14.

That is, as shown in FIG. 4, the outer edge of the corrugated metal lath 8 is inserted into the U-shaped recess of the decorative frame, and the surface of the convex portion 10 of the metal lath 8 and the edge of the upper surface of the decorative frame are The inner surface is fixed by spot welding or the like.

The ceiling member thus integrated is installed on the ceiling of the casing, but in the case of the present invention, the corrugated metal lath 8 doubles as the conventional wire mesh and louver, so in addition to this, special No parts are required.

That is, since the metal lath 8 itself has countless holes formed by press working and has a three-dimensional structure, the opening area is larger than that of the conventional metal lath 8.

Furthermore, by processing the metal lath into a wave shape, a three-dimensional visual effect similar to that of a louver can be obtained.

Furthermore, the corrugation increases the mechanical strength of the metal lath itself, so that even if a heavy object falls, it can sufficiently catch it and prevent it from falling into the casing.

In particular, unlike conventional louvers, it has a simple structure and can be easily manufactured by press working, and it also functions as both a wire mesh and a louver, allowing for fewer parts and materials, resulting in significant cost reductions.

Furthermore, unlike conventional louvers, it can be easily integrated with the surrounding decorative frame by welding, etc. as shown in Figure 4, so there is only one part, making it easy to assemble the casing and store parts. become.

3 and 4 are examples in which the unevenness is formed in a waveform in only one direction, but as shown in FIG. 5, the four parts 9' and the convex parts 10' are formed alternately in the A formed metal lath may also be used.

[Brief explanation of the drawing]

Fig. 1 is an exploded perspective view of the ceiling of a conventional electronic device housing, Fig. 2 is an enlarged perspective view of a conventional louver, Fig. 3 is a perspective view of a metal lath type ceiling member according to the present invention, and Fig. 4 is its perspective view. FIG. 5 is an enlarged perspective view of a main part, and FIG. 5 is a perspective view showing another embodiment. In the figure, 2 is a wire mesh, 3 is a louver, 8 is a corrugated metal lath, 9.9' is a recessed part, 10.10' is a convex part, 11.
...14 is a decorative frame.
