Abstract

PROBLEM TO BE SOLVED: To provide a showing case capable of adjusting the height, by screwing a shaft part with a male screw extended upward from a floor contact part of a floor contact body into a screw hole equipped on an inward facing setting member on bottom corners of a box body and equipping a spanner applying part on the tip part of the shaft part extended upward from the screw hole. SOLUTION: An adjuster 3 is constituted by screwing a shaft part 3b with a male screw extended upward from a floor contact body 3a into a screw hole 7 fixed by welding, etc., to the lower face of the horizontal part of an attaching member 6 attached on a lower beam member 5 of a box body 1. At the tip part of the shaft part 3b with a male screw extended upward from the screw hole, a spanner applying part 3c is provided. The spanner applying part 3c is integrated with the lower end part of the shaft part 3b with a male screw and is made rotatable relative to the floor contact body 3a and connected in a relation prevented upward drawing off. Thus, even in the case one cannot or hardly can approach the showing case, the height can be easily adjusted.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display case having floor-adjusting floor-contact legs.

[0002]

2. Description of the Related Art A conventional height-adjustable floor-contacting leg called an adjuster generally has a columnar shaft portion having a male screw threaded vertically fixed to the center of a disk-shaped floor-contacting body. In addition, a wrench hooking portion to which a rotation loosening device such as a wrench can be fitted is provided in the lower portion of the shaft portion. This floor contact leg is attached by screwing into a screw hole provided in a corner of the lower part of the display case, and a spanner or the like is applied to the spanner hooking part exposed below the display case to rotate the shaft part. It is moved to adjust the height of the display case.

[0003]

In the above-mentioned conventional display case, the display cases are arranged in close contact with the wall surface, or as shown in FIG. 3, several display cases are arranged side by side. If you do, the spanner hook on the bottom of the display case
There was a problem that the height could not be adjusted due to the floor-contacting legs that could not be hung with a spanner, etc., hidden behind the wall surface or the connected display case.

It is an object of the present invention to provide an exhibition case having floor-contacting legs whose height can be easily adjusted even when it is placed in close contact with a wall surface or connected laterally.

[0005]

According to the present invention, the above-mentioned problem is solved as follows. (1) In an exhibition case having height-adjustable floor-contacting legs at the lower corners of the housing, the screw holes provided on the inward-facing mounting members at the lower corners of the housing are used to connect the floor-contacting legs. A shaft portion with an external thread extending upward from the floor body is screwed, and a spanner hooking portion is provided on the top of the shaft portion extending above the screw hole.

(2) In the above item (1), an extension shaft portion having a spanner hooking portion is provided at the top of the male screw shaft portion extending above the screw hole of the mounting member.

(3) In the above item (1) or (2), the external threaded shaft portion of the floor-contacting leg is provided with a spanner hook portion below the mounting member at the lower corner of the housing.

(4) In any one of the above items (1) to (3), only the floor-contacting leg at the lower corner of the rear portion of the housing is the floor-contacting leg provided with a shaft portion having a spanner hooking portion at the top. To do.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION FIG. 1 is a cross-sectional view showing one lower part of an exhibition case (A) in which three units are laterally connected as shown in FIG.

In addition to the casters (2), height adjustable floor contact legs, that is, adjusters (3) and (4) are provided at the front and rear corners of the lower part of the housing (1) of the display case (A). It is provided. The front plate (1a) of the housing (1) can be opened.

The adjuster (3) on the front part has a disk-shaped floor contact body (3a) and a male screw extending upward from the center of the upper part of the floor contact body (3a), as in the case of the conventional display case. Shaft (3b)
And This adjuster (3) is provided in a screw hole (not shown) of a nut (7) fixed to the lower surface of a horizontal portion of a mounting member (6) mounted on a lower beam member (5) of a housing (1) by welding or the like. , By screwing the male threaded shaft (3b),
It is mounted so that its height above the floor can be adjusted.

Above the floor contacting body (3a) and below the horizontal portion of the mounting member (6), the male threaded shaft portion (3b) is provided with a spanner hooking portion (3c). In this embodiment,
The wrench hook (3c) is integral with the lower end of the shaft portion (3b) with external thread, and is rotatable relative to the floor contact (3a) and is prevented from slipping upward. Are combined.

A rotary loosening device (not shown) such as a spanner inserted into the spanner hanging portion (3c) from a gap left between the lower portion of the casing (1) and the floor surface is engaged. By fitting them together, the male threaded shaft portion (3b) can be rotated with respect to the nut (7) integral with the mounting member (6) to adjust the height of the adjuster (3).

Similarly, the rear adjuster (4) is also provided with a disk-shaped floor contacting body (4a) and a male threaded shaft portion (4b) extending upward from the upper center of the floor contacting body (4a). ing. This adjuster (4) is provided with a male screw in a screw hole (not shown) of a nut (7) fixed to the lower surface of a horizontal portion of a mounting member (6) mounted on a lower beam member (5) of a housing (1). It is attached to the housing (1) so that its height from the floor can be adjusted by screwing the attached shaft portion (4b).

The rear adjuster (4) also has a flooring
Above the (4a) and below the horizontal portion of the mounting member (6), the external threaded shaft portion (4b) is provided with a spanner hooking portion (4c).

Shaft with male thread for rear adjuster (4)
A relatively long extension shaft portion (8) is fitted on the top of (4b). That is, the tip of the male threaded shaft portion (4b) is screwed into and fixed to the screw hole formed at the lower end of the extension shaft portion (8). A spanner hooking portion (9) is formed on the top of the extension shaft portion (8). This situation is shown magnified in FIG.

[0017]

According to the present invention, the front plate of the display case is opened, and the wrench is loosened at the top of the shaft portion with the male screw extending long above the screw hole of the mounting member at the bottom of the housing. By operating by tightening the fastening device, even if it is difficult or difficult to access from the outside of the display case, such as an adjuster at the position close to the wall or the adjacent display case,
The height can be adjusted very easily.

According to a second aspect of the present invention, when an extension shaft portion having a spanner hooking portion is formed on the top of the male threaded shaft portion extending above the screw hole of the mounting member, a conventional standard type adjuster is provided. It can be used as it is.

According to a third aspect of the present invention, if a spanner hook portion is provided on the male threaded shaft portion of the floor-contacting leg even below the mounting member at the lower corner of the housing, it can be easily mounted from the outside of the display case. If accessible, the height can be adjusted in the conventional manner.

According to the fourth aspect of the present invention, if only the floor-contacting legs at the lower corners of the rear part of the housing are floor-contacting legs provided with the extended shaft portions, the design change points are minimized and the initial stage is reduced. It is possible to exert an effect.
