Description

[Detailed description of the invention] This invention relates to a stacked structure of two casings each having a foot and a foot rest.

Conventionally, when stacking two cases, the feet screwed to the bottom surface of the lower frame of the upper case fit into the foot holders screwed to the flat surface of the upper frame of the lower case. Ta.

Figure 1 shows a conventional example of a stacked state of two casings viewed from the side, and Fig. 2 shows a front view of the fitted state of the legs and footrests when the two casings of Fig. 1 are stacked. This shows a cross-section seen from.

Attach the feet 3 to the lower frame 2 near the four corners of the bottom surface 1a of the housing 1.
are screwed, and truncated cone-shaped foot supports 6 are screwed to the upper frame 5 near the four corners of the flat portion 4a of the casing 4 so as to face the legs 3.

The foot 3 has a cylindrical shape and has a fitting hole 7 in the bottom surface thereof into which a foot rest 6 is fitted.

However, if the foot rests are attached to the flat surface of the housing, the feet and foot rests are not integrated with the housing, so when installing the feet and foot rests on the housing, the center position of each is fixed. It was a pain to install them together.

In addition, although it works well when housings with the same depth are stacked on top of each other, when housings with different depths are stacked on top of the same housing, the positions of the feet and the foot rests sometimes do not match.

Therefore, in order to reinstall the footrests, it was necessary to modify the housing and change the position of the footrests, or to install separate footrests in advance so that cases with different depth dimensions could be stacked. The cost is also high,
In the latter case in particular, six footrests protruded from the flat surface of the housing, making it unsightly.

Furthermore, since the foot rests are structured so as to protrude from the flat surface of the casing, when a casing having a structure different from that of the casings to be stacked is placed on top of the other, the foot rests collide with the foot rests, which is inconvenient.

This idea was devised in view of the above-mentioned problems, and by forming the foot rests on the left and right upper frames of the casing with steps that are approximately L-shaped and cut to a desired length, the foot rests can be placed on the frames. The present invention provides a stacked structure of the housing in which the feet are either integrally provided with the lower frame of the housing or are attached by fitting into positioning steps cut in advance on the lower frame. be.

This idea will be explained below.

Fig. 3 shows the first embodiment of this invention, showing the state in which the two casings are stacked together, and Fig. 4 shows the fitted state of the legs and footrests when the two casings in Fig. 3 are stacked, from the front. FIG.

The foot rest 20 is a stepped portion 24 formed by cutting the outer upper edges 23a, 23'a of the left and right upper frames 23, 23' of the housing 21, 22 to a desired length in a substantially L-shape along the longitudinal direction thereof. , 24', and the upper frame 23 and 23' are used for both purposes.

The foot 25 has a bow-like shape and is composed of a mounting portion, a leg portion, and a protruding portion.

The mounting portions 25a are attached to the outer lower edges 26a, 26'a of the left and right lower frames 26.26' of the housing 21.22, respectively.
The left and right lower frames 26.
It is attached to the outer surface of 6' with screws 28.

The distance α in the longitudinal direction between the stepped portions 24 and 24' is slightly wider than the distance β between the leg portions 25b of the legs 25 attached to the front and back of the outer surface of the lower frame.
．． The distance α' between the two legs 24' facing each other is slightly narrower than the distance β' between the left and right leg portions 25b of the legs 25 attached to the left and right lower frames 26 and 26'.

Therefore, the leg portions 25 b fit into the step portions 24 , 24 ′ to prevent the casings 21 .
Prevents back and forth movement.

The protrusion 25C is for providing a gap between the cases 21 and 22 when they are stacked.

Further, the legs 25 can be made into an ♂ shape and can be attached to the lower surface of the lower frame by sharing the attachment portion and the protruding portion.

Furthermore, as shown in FIG. 5, the legs can be formed integrally with the lower frame.

Note that the stepped portions 24, 24' are extended in the front-rear direction and are cut, so that a short-depth casing can be placed thereon without any problem.

In this case as well, even if the short-depth casing moves back and forth, the leg portion 25 of the casing remains at the end 20' of the stepped portions 24, 24'.
Since it comes into contact with, it prevents its movement.

FIG. 6 shows a second embodiment of this invention, in which when the depth dimensions of the stacked casings are constant, the foot rests 28 and casings 29.
The outer upper edges of the upper frames 31 and 31' of each of the upper frames 31 and 30 may be shaped along the longitudinal direction with step portions 33 and 33' that are cut long enough to fit with the legs 32 in a substantially L shape. .

Note that the leg 32 has the same shape and structure as in the above embodiment.

As explained above, the frame can also serve as a foot rest by forming the foot rest with a stepped part that is cut down to a desired length in a roughly L-shape along the longitudinal direction of the outer upper edge of the left and right upper frames of the casing. However, since the legs are attached independently to the lower frame of the housing or are integrally formed, the following effects can be obtained.

(a) There is no need to make the footrest itself independently.

(b) Since the footrests do not protrude from the flat surface of the casing, casings having a structure different from the casings to be stacked can be placed without any problem.

(c) By extending the stepped portion forming the footrest to an arbitrary length, housings of different depths can be easily stacked.

(2) Due to the structure, it is not necessary to align the feet and the foot rests.
