〔Example〕

FIG. 1 is a perspective view for explaining the basic configuration of the present invention.

The casing installation structure of the present invention is characterized in that the casing 1 is installed and fixed on the floor while being placed on a stand 10 of a special structure prepared separately.

This stand lO has a rectangular planar shape that matches the bottom shape of the housing 1, and is accurately leveled and fixed in advance by means such as anchor bolts at a predetermined location on the floor where the housing 1 is installed. There is.

The stand 10 is composed of a pair of left and right rail sections 11 that form a flat horizontal surface with a predetermined width, and a vertical wall-shaped stopper section 12 that connects their rear ends. A horizontal housing receiving surface 13 whose height is lower than the rail portion (almost the same as the floor surface) is formed. The relationship A>W>a is required between the outer dimension A, the inner dimension a, and the width W of the housing 1 between the rail portions 11. 1 can be placed on both sides of the bottom surface on the rail portion 11.

A front stop plate 14 hinged to the front ends of both rail parts 11 is attached to the front side of the housing receiving surface 13. As shown in FIG. 2, when this front stop plate 14 rotates forward, its front edge contacts the floor surface as shown by the chain line, and its back surface extends to the housing receiving surface 13. Forms the guide surface of the caster, but at the solid line position where it contacts the top surface of the rail portion 11. The front surface of the housing receiving surface 13 is configured to be closed.

A pair of left and right bottle-shaped locking protrusions 15 are protruded from the stopper portion 12 and are adapted to engage with locking holes (not shown) provided on the back side of the housing 1 .

On the other hand, the housing 1 is provided with four casters 2 on its bottom as usual, and can be moved on the floor by these casters until it is installed on the floor.The features of the present invention will be described later. In order to do this, the height of the caster 2 can be variably adjusted within a predetermined range. That is, when traveling on the floor, the height is set to be relatively high so as to leave a predetermined distance between the bottom surface of the casing and the floor surface, and the installation is sometimes adjusted to a lower height than this.

Regarding the installation of the casing of the present invention having such a configuration, the installation procedure based on the structure will be explained.

First, the stand 10 is fixed to a predetermined location on the floor where the housing 1 is to be installed using anchor bolts or the like. and,
The housing 1 is moved on casters to be positioned in front of the stand 10, and their axes are made to coincide with each other. At this time, front stop plate 1
4 is rotating forward. It functions as a guide surface that reaches the housing receiving surface 13. The casing 1 is moved on casters and pushed into the casing receiving surface 13 as it is. As described above, since the height of the casters 2 is set at a high position, the bottom surface of the housing 1 can enter the stand 10 without interfering with the rail portion 11. A locking protrusion 15 whose back surface protrudes from the stopper part 12
The caster 2 stops at a position just before reaching the height, and the caster 2 is adjusted to lower its height. As a result, the bottom surface of the housing 1 rests on the top surface of the rail section 11, and conversely, the casters 2 are placed in a floating state above the floor.

Next, the housing 1 further slides on the rail portion ll and is pushed inward. Then, the locking protrusion 15 engages with the locking hole on the back of the housing. The housing itself comes into contact with the stopper portion 12 and stops. As a result, the rearward movement of the housing 1 is restricted, and the vertical and horizontal movements of the rear part of the housing 1 are fixed.

In this state, the front stop plate 14 is rotated rearward to close the front opening of the housing receiving surface 13, and the stepped portions 14a at both ends of the 7 are brought into contact with the side surface of the housing and the top surface of the rail portion 11. position. (20) Screw holes are provided on the side surface of the housing and on the top surface of the rail portion in the contact area, and corresponding holes are provided on the front stop plate 14, so the bolt 16 is screwed through these holes, Fix both. This restricts the forward movement of the casing 1 and also prevents the casing 1 from moving forward.
The front part of the front part is fixed against vertical and horizontal movement by a front stop plate 14.

Next, the structure of the height-adjustable caster 2 of the present invention, which is attached to the bottom surface of the housing 1, will be explained based on FIG.

This caster 2 is. A nut body 21 welded and fixed to the inside of the bottom plate 20 of the housing, and a bolt body 22 screwed thereto.
The tip region of the unthreaded bolt body 22 protruding from the underside of the bottom plate has a hexagonal cross section. A known caster wheel 2 is mounted at the tip of the housing with a predetermined gap from the bottom surface of the housing and can take any direction in the horizontal plane.
3 is fixed with a screw 24.

To adjust the height of the caster, insert the spanner 25 through the gap on the bottom of the housing 1, and tighten the bolt body 22.
The bolt body 22 may be moved in the vertical direction relative to the nut body 21 by grasping and rotating the hexagonal cross-sectional area.

4 to 7 show other examples of the caster 2.

A horizontal shaft 31 fixed to one end of the lever 30 is supported on the bottom surface of the housing 1, and one end of a first link 32 is fixed to the horizontal shaft 31. One end of a second link 33 is pivotally supported on the other end of the first link 32, and the other end is pivotally supported on the front part of the caster body 34. The caster body 34 is supported by a horizontal shaft 35 on a bracket 36 attached to the bottom of the housing.

In this configuration, the lever 30 is fixed to the housing by the thumbscrew 38 in the position shown in FIG.
stand upright and support the bottom of the housing at the highest position farthest from the floor. When the casters are in this position, the housing 1 can run on the floor. In the figure, the lever 30
Tilt counterclockwise to the 5th i! When the caster 2 is in the position l, the link mechanism rotates the caster 2 clockwise about the horizontal shaft 35, so the bottom of the housing relatively moves downward and the distance from the floor becomes smaller.

If you perform this operation when placing the casing on the stand mentioned above. It becomes possible to smoothly transfer the weight of the housing from the casters to the stand.

As shown in FIG. 7, this caster rotation mechanism is preferably positioned and installed on the bottom surface of the housing 1 so that the lever 30 rotates along and parallel to the front and rear surfaces of the housing 1. In this way, the lever 30 is attached to the housing until the housing 1 is placed on the stand 10, and then removed from the housing so as not to get in the way, and the lever 30 is attached to the storage box 37 provided at the rear of the stand 10. It can be stored inside.

By employing such a lever link mechanism, even one worker can smoothly raise and lower the heavy housing with less force.

The installation structure using the above-mentioned stand is applicable to the case where multiple casings are installed in parallel, as shown in FIG. Place casing 1 on and secure it. Then, a front cover 40 and a rear cover 4 are provided to reduce the gap between the housing 1 and the adjacent housing 1.
1 and the front stopper plate 14 may be bolted to the upper surface of the rail portion of the stand 10, and the upper end thereof may be fixed to the top plate of each housing.

〔Effect of the invention〕

As detailed above, according to the present invention, the casing is installed on the floor via a stand, and the bottom of the casing is placed on the rails of the stand that are leveled in advance, so that the load is reduced. It becomes even and the structural strength increases, making it possible to perform reliable installation in a short time and with fewer man-hours.
