Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to, for example, a leg structure of an audio equipment case.

[Prior Art] Most conventional legs of this type have the structure shown in FIG.

That is, it has a structure in which legs 01 made of rubber or synthetic resin molded products are fixed to the bottom plate 02 of the equipment case using fasteners such as screws 03, and the legs 01 are made of rubber or synthetic resin molded products.
Fixed in the corner.

[Problems to be solved by the invention] The leg structure of the above configuration uses a leg 01 having a constant height.

This is because it is assumed that the floor surface 04 to be placed is flat.

However, there are many cases where it is necessary to place the device on an uneven floor or on top of other equipment, and in such cases, other cushioning materials are interposed between the floor and the legs of the equipment. However, there was a noticeable flaw in its appearance.

[Means for Solving the Problem] This invention is a leg disposed between the bottom plate of the device and the floor surface, a protruding piece is formed on the surface of the leg opposite to the bottom plate, and the bottom plate has the above-mentioned projection piece. A leg structure of an equipment case in which a plurality of recesses through which protrusion pieces are inserted are formed concentrically, and holes corresponding to the shape of each step of the stepped protrusion are bored concentrically, and the recesses have different depths. It is.

[Example] This invention will be described below with reference to an example. In Figs. 1 and 2 a and b, 1 is a leg made of a synthetic resin molded product, and has a hole 1a in the center through which a screw 3 is inserted.
is formed, and a protruding piece 1b is formed on the surface facing the bottom plate 2 of the device.

At least two or more, preferably three or more protrusions 1b are arranged concentrically.

On the other hand, in the bottom plate 2, recesses 2b, 2c, and 2d into which the protruding pieces 1b are inserted and locked are formed concentrically corresponding to the protruding pieces.

The depth of each of the recesses is increased in the order of 2b, 2c, and 2d.

In the above configuration, the leg 1 is fixed to the bottom plate 2 with a screw 3 via a spring 5.

Figure 2a shows the case where the projection piece 1b is locked in the recess 2b with the smallest depth, and Figure 2b shows the case where the projection piece 1b is locked in the recess 2d with the largest depth. The difference in distance between the floor surface 4 and the bottom plate 2 corresponding to the difference in depth between the recesses 2b and 2d is obtained.

That is, in the embodiment of the leg structure of this invention, the distance between the floor surface and the bottom plate can be changed in three stages.

To change the height position of the leg, pull the leg 1 downward against the elastic force of the spring 5, rotate it so that the protrusion piece aligns with the desired recess, and then remove the tension. , the leg moves upward due to the elastic force of the spring 5, and the protrusion piece is locked in the desired recess.

[Effects of the invention] According to the invention explained above, the height of the legs fixed to the four corners of the equipment case can be adjusted independently, and the height of the legs fixed to the four corners of the equipment case can be adjusted independently. The device can be adjusted so that it is horizontal.

Note that the shape of the protrusion is not limited to the shape shown in the embodiment, and various shapes can be adopted, and the recess may be formed in a shape through which the protrusion piece can be inserted and locked.

Furthermore, although the spring in the embodiment has the effect of simplifying the adjustment work, the invention of the present invention does not apply even if it is omitted or if it is simply interposed between the bottom plate of the device and the floor surface without being fixed with screws. The main purpose of this can be achieved.

[Brief explanation of the drawing]

Fig. 1 is a partially cutaway perspective view of the leg structure of this embodiment of the invention, Figs. 2a and b are sectional views of the leg structure of this embodiment of the invention, and Fig. 3 is a sectional view of the conventional leg structure. .

Claims (1)

[Scope of utility model registration request] A leg arranged between a bottom plate of a device and a floor surface, wherein a protruding piece is formed on a surface of the leg opposite to the bottom plate, and a plurality of recesses through which the protruding pieces are inserted are formed in concentric circles in the bottom plate. A leg structure for an equipment case, characterized in that the recesses have different depths.
