BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a free-standing cabinet installation structure. As shown in FIG. 4, a self-standing cabinet 1 for housing an electronic device generally has a vertically long box-shaped structure having doors on a front surface or front and rear surfaces.

A caster 2 is mounted near each of the four corners of the cabinet bottom plate 11 so that the caster 2 can be easily transported to an installation location by rolling. The cabinet provided with the casters in this way is fixed to the floor via fixing brackets after being transported to a predetermined installation place, and measures are taken so that the cabinet does not start moving due to vibration or fall over due to an earthquake or the like. Is required.

[0003]

2. Description of the Related Art FIG. 5 is a perspective view of a conventional example, and FIG. 6 is a side sectional view of the conventional example. As shown in FIG. 6, in the conventional cabinet 1, casters 2 are mounted near four corners of the cabinet bottom plate 11, and a fall prevention metal fitting 3 is mounted on the cabinet bottom plate 11 outside the rear caster 2.

[0004] The fall prevention fitting 3 is provided with a head plate member 3A at the lower end of a screw member 3B. Cabinet bottom plate 11
The screw member 3B is screwed into a vertical screw hole of the screw member 12 for attachment by welding or the like to the lower surface of the cabinet, so that the fall prevention fitting 3 is attached to the cabinet 1.

On the front side of the cabinet bottom plate 11, there is provided a locking plate member 13 projecting vertically downward. on the other hand,
Conventionally, in order to fix the cabinet 1 to the floor 5, FIG.
As shown in FIG. 6, a rear fixing bracket 20 is fixed to the floor 5 near the wall 6 so as to be parallel to the wall 6, and before the rear fixing bracket 20 is fixed to the floor 5 so as to be parallel to the rear fixing bracket 20. And a fixing part 30.

The rear fixing bracket 20 has a length of the cabinet 1.
A side view with an upper opening substantially equal to the left and right width of the channel-shaped fixing plate portion 21 and an upper edge near the left and right end portions of the fixing plate portion 21 are provided so as to protrude toward the near side. And an engagement plate portion 22 which is shaped (opened downward).

The arrangement pitch of the engagement plate portions 22 is equal to the arrangement pitch of the fall prevention metal fittings 3. A guide groove 23 is formed in the horizontal plate portion of each engagement plate portion 22 in a tapered shape in which the front side expands, into which the neck of the fall prevention fitting 3 is pushed.

Note that the upper edge of the rear plate portion of the fixing plate portion 21 is bent rearward at a right angle to reinforce the strength of the rear fixing bracket 20. The rear fixing bracket 20 is placed with the lower surface of the fixing plate 21 in close contact with the floor 5, a bolt 25 is inserted into a hole provided in the fixing plate 21, and screwed to an anchor nut (not shown) embedded in the floor 5. Thereby, it is fixed to the floor 5 so as to be parallel to the wall 6.

The front fixing bracket 30 has an angle shape in a side view composed of a horizontal plate member 31 and a vertical plate member 32, and is sufficiently smaller than the distance between the left and right casters whose lengths are arranged. Further, a pair of female screw members 14 are attached to the back surface side of the vertical plate member 32 at a desired interval by welding or the like.

The front fixing bracket 30 is mounted with the lower surface of the horizontal plate member 31 in close contact with the floor 5 and bolts are inserted into holes formed in the horizontal plate member 31.
By inserting 35 and screwing it to an anchor nut (not shown) embedded in the floor 5, it is fixed to the floor 5 on the front side of the rear fixing bracket 20 in parallel with the rear fixing bracket 20.

To install the cabinet 1 on the floor 5, the casters 2 are rolled and pushed toward the wall 6, and the neck of the fall prevention fitting 3 is inserted into the guide groove 23 of the rear fixing fitting 20. Then, the back surface of the locking plate member 13 is brought into contact with the vertical plate member 32 of the front fixing bracket 30, the bolt 36 is inserted into the hole of the locking plate member 13, and screwed into the female screw member 14, whereby the cabinet 1 Is fixed to the front fixing bracket 30.

Since the cabinet 1 is installed in this manner, even if an earthquake or the like occurs, the casters 2 roll and the cabinet 1 does not move off the floor. Fall prevention fitting 3
The head plate member 3A is locked to the engagement plate portion 22 of the rear fixing bracket 20, so that the cabinet 1 does not fall.

[0013]

The above-mentioned rear fixing bracket has a fixing plate portion fixed to the floor behind the engaging plate portion, and a reinforcing member provided at the rear portion behind the fixing plate portion.

For this reason, a space larger than the width of the fixing plate is required between the back surface of the cabinet and the wall. That is, the conventional installation structure has a problem that the occupied floor area increases.

The present invention has been made in view of such a point, and an object of the present invention is to provide a cabinet installation structure in which the occupied floor area required for installation is reduced.

[0016]

In order to achieve the above object, the present invention, as illustrated in FIG. 1, moves four casters disposed on a cabinet bottom plate and a lower portion of the cabinet bottom plate in a front-rear direction. A pair of reinforcing members having a U-shape in front view and a head plate member at the lower part of the vertical neck, and a fall prevention attached and disposed near the respective reinforcing members on the lower surface of the cabinet bottom plate. A cabinet having a pair of fixing brackets 50 such that their rear ends are close to the wall 6 and are orthogonal to the wall 6 and are arranged in parallel at an interval equal to the interval between the pair of overturn prevention brackets. 5 and fixed.

Each of the fixing brackets 50 has a bottom plate member 51 having a length substantially equal to the length of the reinforcing member in the front-rear direction, and a left and right side edge of the bottom plate member 51 which are respectively perpendicular to the floor surface. A pair of bent side plate members 52, a pair of upper plate members 53 and 54 formed by bending the upper edges of the respective side plate members inward at right angles, and the upper surfaces match the upper surfaces of the upper plate members 53 and 54. Engaging plate members connecting the rear portions of the pair of upper plate members 53 and 54
55, and a tapered guide groove 56 formed in the engagement plate member 55 so that the front side is widened and into which the neck of the fall prevention fitting is pushed.

The upper plate member 53 has a structure in which the upper surface is in close contact with the lower surface of the reinforcing member and is fixed to the reinforcing member by bolts 61 in a state in which the fall prevention metal fitting of the cabinet is fitted to the engaging plate member 55. And

[0019]

According to the present invention, the fall prevention fitting fixed to the cabinet is fitted to the engaging plate member of the fixing fitting fixed to the floor, and the reinforcing member of the cabinet is fixed to the fixing fitting.

Therefore, even if there is an earthquake or the like, the casters do not roll and the cabinet does not move off the floor. Further, since the head plate member of the fall prevention fitting is locked to the engagement plate member, the cabinet does not fall.

On the other hand, the length of the fixing bracket in the front-rear direction is substantially equal to the front-rear length of the cabinet, and the fixing bracket is fixed to the floor with its rear end close to the wall. Therefore, the cabinet can be installed on the floor, with the back side close to and close to the wall. Therefore, the occupied floor area required for installing the cabinet is small.
