BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slide rail attachment device for an electronic equipment rack for attaching a slide rail for supporting the equipment cases in a retractable manner to the inside of the electronic equipment rack. .

[0002]

2. Description of the Related Art In a rack for electronic equipment, a slide rail mounting device has a structure which can be attached to and detached from a frame of the rack so that the slide rail can be mounted according to the equipment to be stored. There is.
Therefore, conventionally, as shown in FIG. 4, a mounting plate portion 35 is bent and formed at a base end of a rail bracket 33 for mounting a fixed side rail 43 of a slide rail, and the mounting plate portion 35 is mounted on a vertical frame 36 of a rack. Of the nut fitting groove 37 formed on the front and rear surfaces of the
The structure in which the slide nut 38 fitted to the above is fixed with the bolt 39 is common.

[0003]

However, in this prior art, since the rail bracket 33 is fixed to the slide nut 38 fitted in the vertical nut fitting groove 37 with the bolt 39, it is possible to fix the rail bracket 33 against heavy objects. I was worried. Further, when fixing the slide rail to the rail bracket, the bolt 39 must be tightened from the fixed rail side 43 of the slide rail while holding the nut 42 on the back side of the slide rail mounting hole 41 of the rail bracket 33. 33 is attached to the vertical frame 36 while holding the slide nut 38 and the bolt 39.
Since the driver 40 must be rotated in the direction parallel to the rail bracket 33, the mounting work is difficult to perform. The present invention has been made to solve the above-mentioned conventional problems, and to provide a slide rail mounting device for a rack for electronic equipment, which can stably support the weight and is easy to mount.

[0004]

SUMMARY OF THE INVENTION The present invention, which has been made to solve the above problems, forms a slide rail holding surface having a flanged groove for fitting a nut on the inner side surface, and
The rail bracket main body, which has the mounting surface for the frame with the flanged groove for nut fitting on the outer surface, was attached to the frame using the nut fitted in the flanged groove on the outer surface. It is a feature.

[0005]

In the slide rail mounting device of the present invention thus constructed, the rail bracket main body having the nut fitted in the flange for fitting the nut is brought into close contact with the inner surface of the vertical frame of the rack. A bolt inserted from the outer surface of the mounting hole provided in the above is screwed into the nut to attach the rail bracket main body to the frame. Next, fit the nut in the flanged groove for nut fitting provided on the slide rail holding surface of the rail bracket body, insert the bolt from the screw insertion hole provided in the guide rail of the slide rail, and then screw it into this nut. And attach the guide rail.
Then, the guide rails can be engaged with the moving-side rails attached to the side surfaces of the cases so that the cases can be supported so as to be pulled out from the rack.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described in detail with reference to FIGS. In FIG. 2 and FIG. 3, reference numeral 1 denotes a horizontally elongated rail bracket main body formed by extruding an aluminum alloy, and an inner surface of the rail bracket main body 1 has a concave shape for holding a fixed rail 21 of a slide rail. The slide rail holding surface 2 is formed. Reference numeral 3 denotes a flanged groove for fitting a nut, which is provided inside the slide rail holding surface 2 from the tip to the base end.

Reference numeral 4 denotes a mounting surface for mounting the rail bracket main body 1 on the inner side surface of the vertical frame 12 of the rack 11, which is formed on the outer side surface of the rail bracket main body 1. The mounting surface 4 is provided with a flat surface portion attached to the inner surface of the vertical frame 12, and a flanged groove 5 for fitting a nut is provided inside the flat surface portion from the tip to the base end.

FIG. 1 shows an example of a rack 11. The rack 11 has side plates (not shown) which can be attached and detached to expose the vertical frames 12 arranged on both sides. As shown in FIG. 2, each vertical frame 12 includes a side plate 1
In addition to connecting the bending piece 14 for reinforcement in front of and behind 3,
Elongated holes 15 for inserting bolts for mounting slide rails are provided in the side plate portion 13 at equal intervals in the vertical direction. In the embodiment, the long holes 15 are provided in two rows in the vertical direction.

In the slide rail mounting device of the present invention thus constructed, as shown in FIG. 3, a flanged groove 5 for fitting a nut is provided in series from the front end to the inner end of the mounting surface 4. 2 nuts 25 in the groove 5 with the collar.
, The mounting surface 4 is attached to the inner side surface of the side surface plate portion 13, the bolt 26 is inserted from the outside of the side surface plate portion 13 into the elongated hole 15, and the nut 25 is screwed. The rail bracket body 1 is attached to the vertical frame 12 of the rack 11.

In this way, the rail bracket body 1
1 is attached to the vertical frame 12 as shown in FIG. 1, the nut 25 is fitted into the nut fitting flange 3 provided on the slide rail holding surface 2 of each slide rail mounting device,
A bolt 27 is inserted through a screw insertion hole provided in each slide rail holding surface 2 and then screwed into a nut 25 to attach the fixed rail 21 of the guide rail. The fixed rail 21 is engaged with the movable rail 28 attached to the side surface of the case so that the case can be pulled out from the rack.

[0011]

As is apparent from the description of the above embodiment, the present invention is one in which bolts are screwed onto the nuts from the outside of the side plate portion, so that a screwdriver or the like for tightening the bolts is used for rails. It can be operated from the direction perpendicular to the bracket body. Further, since it is not necessary to hold the nut with one hand when mounting, unlike the conventional case, the mounting work becomes easy. Further, it has an advantage that it can be easily positioned in the height direction and leveled, and it can easily cope with a change in the specifications of the rack, so that it will not fall even if it receives weight. Therefore, the present invention has an extremely great practical value as a slide rail mounting device for an electronic device rack that solves the conventional problems.
