Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rack mounting column for mounting a rack.

[0002]

2. Description of the Related Art FIG. 5 is a perspective view for explaining a conventional rack mounting column. In FIG. 5, 1 is a rack mounting column, A is a rack conforming to the JIS standard (Japanese Industrial Standard), and B is a rack conforming to the EIAJ standard (Japanese Electronic Machinery Industrial Standard).

A printed wiring board on which various electronic parts are mounted is housed in racks A, B, ... In addition, racks A, B,
Each of ... Has front plates A _1, B _1, ... For attaching to a pair of parallel rack-mounting columns 1, _1, and both side ends of the front plates A _1, B _{1 ,} . In the vicinity thereof, notches A ₂ , B ₂ , ... For screwing the racks A, B ,. Further, the pair of rack mounting columns 1 and 1 are provided with a plurality of mounting screw holes 11 having an appropriate pitch so that the racks A, B, ... Therefore, with the front plates A _1, B _1, ... Of the racks A, B, ... Each rack A, B, ... is inserted and front plates A _1, B are inserted.
_{When the} notch portions A ₂ , B ₂ , ... provided in _1, ... are aligned with the respective mounting screw holes 11 and the fixing screws 2 are tightened, each rack A, B, ... is paired. Can be attached to the rack mounting columns 1 and 1.

[0004]

However, there are two types of racks A, B, ... As described above, the rack A conforming to the JIS standard and the rack B conforming to the EIAJ standard. Moreover, the mounting pitch dimension differs depending on the two types. That is, as shown in FIG. 5, the mounting pitch dimension W _a of the rack A conforming to the JIS standard is different from the mounting pitch dimension W _b of the rack B conforming to the EIAJ standard. Therefore, each time the mounting screw hole 11 of the rack mounting column 1 is provided, is the rack mounted at that position conforming to the JIS standard, or is it EI?
There is a problem that the mounting screw hole 11 cannot be processed unless it is confirmed whether the rack conforms to the AJ standard, which is inconvenient.

The present invention has been made in order to solve the above problems, and an object of the present invention is to provide a rack mounting column having general versatility that does not require consideration of the rack mounting pitch dimension. To provide.

[0006]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a pillar main body provided with a continuous recess having a narrowed opening in the form of a groove in the longitudinal direction, and without protruding from the opening. A rack mounting column comprising a fixture that can slide freely in the recess in the longitudinal direction, wherein a screw hole is provided in a portion of the fixture that faces an opening of the recess. .

[0007]

With the above-mentioned structure, the fixture provided in the continuous recessed portion of the opening of the column body of the rack mounting column can slide freely in the recessed portion in the longitudinal direction. A screw hole is provided in a portion of the fixture facing the opening of the recess. Moreover, the portion of the fixture facing the opening of the recess is deeper than the opening. Therefore, it is wondering whether the pitch dimension of the notch provided in the rack for mounting the rack to the rack mounting column conforms to the JIS standard or the EIAJ standard. Anyway, the cutout portion of the rack is addressed to the opening portion of the column main body of the rack mounting column, and the fixing member is slid to the position of the cutout portion of the rack while being pulled to form the cutout portion of the rack. The screw holes of the fixing tool are aligned with each other, and the notch portion of the rack is fastened to the fixing tool with a screw. Then, the fixing member and the vicinity of the notch of the rack sandwich the portion forming the opening of the column body of the rack mounting column, so that the fixing unit should be fixed to the column body of the rack mounting column. At the same time, the rack is also fixed to the column body of the column for rack mounting.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a rack mounting column according to the present invention will be described in detail below with reference to FIGS. FIG. 1 is a perspective view for explaining a rack mounting column, FIG. 2 is a perspective view showing a column body of the rack mounting column, and FIG. 3 is a perspective view showing a fixture for the rack mounting column. FIG. 4 is a cross-sectional view illustrating the movement of the fixture when the rack is attached.
FIG. 4A shows a state in which the set screw has started to be screwed into the screw hole of the fixture, and FIG. 4B shows a state in which the set screw has been screwed into the screw hole of the fixture and the rack has been fixed. There is.

As shown in FIG. 1, the rack mounting column 1 comprises a column body 10 and a fixture 20. As shown in detail in FIG. 2, the pillar body 10 has a columnar shape having a substantially rectangular appearance, and the pillar body 10 is provided with a continuous recess 12 in which an opening 11 is narrowed in a groove shape in the longitudinal direction. . As shown in detail in FIG. 3, the fixture 20 includes a fixing base 21 that is substantially rectangular in a plan view and is generally U-shaped in a side view, and a square nut 22. The square nut 22 has a substantially square shape, and is welded to the center of the bridging surface of the fixed base 21.

The dimensional relationship between the pillar body 10 and the fixture 20 described above is as follows. That is, the width dimension L ₁ of the fixing base 21 of the fixture 20 is made slightly smaller than the width dimension M ₁ of the recess 12 of the column main body 10. The height dimension L ₂ of the fixing base 21 of the fixing tool 20 is equal to the recess 12 of the support body 10.
Is slightly smaller than the step height height M _{2 of the} above. The height dimension L ₃ of the square nut 22 of the fixture 20 is determined by
Is smaller than the turn-back dimension M _{3 of} . Fixture 20
The width dimension L ₄ of the square nut 22 is slightly smaller than the width dimension M ₄ of the opening 11 of the column main body 10.

The fixture 20 having the above-mentioned relationship is inserted into the recess 12 of the column main body 10 as shown in FIG. Therefore, the fixture 20 can freely slide in the recess 12 of the column main body 10 in the longitudinal direction. Note that, in FIGS. 1 and 4, A indicates a rack. The rack A is intended steel box-like, front plate A ₁ provided for attaching the rack mounting posts 1,1 erected parallel pair on the front, both sides of the front plate A ₁ Notches A _{2 and} A ₂ for screwing the rack A to the rack mounting column 1 are provided near the ends.

Therefore, the rack A can be attached to the rack mounting column 1 having the above-described structure as follows. That is, with the front plate A ₁ of the rack A in the front, the rack A is inserted between the pair of rack mounting columns 1 and 1 standing in parallel from the rear of the rack A. Then, the notch A ₂ provided on the front plate A ₁ is aligned with the opening 11 of the recess 12 of the column main body 10 so as to be aligned. Then, while pulling the fixture 20 toward the position of the notch A ₂ of the rack A, the fixture 20 is pulled to the rack A.
Of is matched with the screw hole 22 _a corner nut 22 of the notch portion A ₂ and the fixture 20, clamp the notched portion A ₂ of the rack A fixture 20 through the screw 3.

At this time, at the beginning of tightening the screw 3,
As shown in FIG. 4 (a), is the fixing base 21 of the fixing tool 20.
And a gap between the tip 10a of the folded portion of the column main body 10
Although there is, there is a fixed base 2 as the screw 3 is tightened.
The gap between 1 and the folded portion tip 10a is reduced. That
Finally, as shown in FIG.

You can.

The present invention is not limited to the above-mentioned embodiment, and the above-mentioned fixture 20 is an upright pillar body 1.
In the recess 12 of 0, since it slides downward and falls naturally, there may be interposed a member that forms a proper sliding resistance between the fixture 20 and the column body 10.

[0016]

Since the rack mounting column of the present invention is constructed as described above, it is completely irrelevant which standard the rack mounting pitch dimension conforms to as in the conventional case. Since there is no need to do so, it is versatile and can be made and stored, and it is possible to provide an excellent rack mounting column that is easy to use.
