〔Example〕

1 and 2 are a sectional view of a first embodiment of a unit mounting structure according to the present invention in an installed state and a perspective view before installation, respectively. In the figure, reference numeral 1 indicates a unit, which is basically the same as that shown in FIG. Reference numeral 10 indicates a pair of left and right unit mounting struts (hereinafter simply referred to as "struts"), each of which is made of channel-shaped material.

A unit support member 20 and a unit fixing member 30 (hereinafter simply referred to as "support member" and "fixing member", respectively) are attached to each of the columns 2 in advance. As shown in FIG. 3, the support member 2o has a step portion 21 for engaging the unit as described later, a threaded portion (female thread) 22, and a detent notch 23 formed at the tip of a round bar, and a snap-locking notch 23 at the rear end. A groove 24 for a ring is formed, and the fixing member 3o is formed in the mounting hole IC of the unit 1 (FIGS. 1 and 6) as described later.
It has a main body portion or a knob portion 31 which also serves as a guide (see a), and a threaded portion (male thread) 32 protruding from the rear end. A vertical groove is formed in the knob portion 31 to prevent slipping.

In particular, as shown in FIGS. 1 and 6 (bl), the support member 20 is fixed to the column 10 with its tip protruding from the unit mounting surface. In other words, as shown in FIGS.
As shown in the figure, the front and rear flanges lQ of the strut 10
Holes 11 and 12 are formed in a and 10b, and the support member 20 is inserted into these holes with the stepped portion 21 at the tip protruding from the outer surface of the front flange 10a. Then, the snap ring 25 is fitted into the snap ring groove 24 of the support member 20 to prevent it from coming off backward, and as shown in FIG. (see Fig. 3) prevents the notch 23 from coming off forward, and the notch 23 itself is attached to the flange 10.
It engages with the straight portion 11a of the oval-shaped hole 11 of a, and is prevented from rotating. Then, the fixing member 30 is screwed into the threaded portion 22 at the tip of the support member 20 with its threaded portion 32.

Now, the work of attaching the unit 1 to the support column 10 is carried out as follows. As shown in FIG. 6, first, the fixing member 30 is slightly loosened and returned to the front. Then, the unit 1 is pushed inward as shown by arrow X, with its mounting hole IC guided by the fixing member 30. Then, the mounting hole IC fits into the protruding tip of the support member 20, and at the same time, the unit falls into the stepped portion 21 under its own weight as shown by arrow Y and is engaged. If the rotating member 30 is then tightened by hand, the mounting plate IB of the unit 1-1 will be tightened between the support member 20 and the fixed member 30 at the stepped portion 21, and as a result, the unit 1 will be attached to the support column 10 as shown in FIG. It will be permanently attached to.

As described above, according to the structure of the present invention, the mounting hole I of the unit
Since C is guided by the fixing member 30 and fitted to the support member 20, alignment is easy. Furthermore, once the unit's mounting hole IC is fitted into the fixing member 30, there is no need to support the unit by hand, which reduces labor.Furthermore, once the unit is engaged with the stepped portion of the support member 20, it will no longer fall off. The danger is gone and you are safe. Therefore, the installation work can be easily carried out by one person. Moreover, the fixed member 30
Tightening can be done by hand and no tools are required.

In addition, in order to remove the unit l-1 from the support 10, after loosening the fixing member 30, lift the unit 1 and pull it out from the fixing member 30 (this can be done easily. Even in this case,
While loosening the fixing member 30, the unit is supported by the support member 20, so there is no need to support it by hand, which reduces labor.

Next, FIG. 7 shows a modification of the unit support member.

This support member 2OA is basically similar to the support member 20 shown in FIG. 3, but the structure of the forward retainer and rotation retainer is different. In other words, the support member 20A includes the support member 20A.
0, there is no cutout 23 on the side surface, and instead, the step part 21 for unit engagement is lengthened, and a straight part 11Aa is formed in the hole 11A of the front flange 10a of the support column 10, and the end surface 21a of the step part 21 is formed in the hole 11A. The stepped portion 21 itself is formed so as to be engaged with the straight portion 11Aa of the hole 11A to prevent it from coming off forward, and the step portion 21 itself is also engaged with the straight portion 11a of the hole 11A to prevent rotation.

This shape of the support member 20A has the advantage that it is easier to process than the support member 20.

Furthermore, FIG. 8 shows another modification of the unit support member. This support member 20B is designed so that when the above-described support member 20 is used, a part thereof can be used in place of this. For example, among the four mounting hole ICs of unit l shown in FIGS. 1 and 2, the support member 20 and fixing member 30 as shown in FIG. 3 are used for the two upper left and right mounting hole ICs, The support member 20B shown in FIG. 8 is used for the two mounting holes IC on the lower left and right sides.

This support member 20B is like an integrated support member 20 and fixing member 30 shown in FIG. 3, and includes a stepped portion or groove 21B for unit engagement, a notch 23B for closing, and a stepped portion 23Ba for preventing the front side from coming out. , has a groove 24 for a snap ring, and its tip is formed as a guide portion 26 for the mounting hole IC of the unit 1. Although not shown, if this is attached to the support column 10 in the same way as the support member 20 in FIG. 3 or the support member 20A in FIG.
The unit 1 can be held in the attached state by guiding it along the guide portion 26 and engaging it with the stepped portion 21B. The fixing force of unit l is the fixing members 30 in two places on the upper left and right.
It can be secured by

Next, FIG. 9 is a diagram showing a unit installation state of a second embodiment of the present invention. In this embodiment, a supporting member 20C and a fixing member 30A as shown in FIG. 10 are used. Fixed member 2
0C has a stepped portion 21 for unit engagement, a groove 24 for a snap ring, and a threaded portion (male thread) 27 is formed at the tip. As shown in FIG. 9, the support member 20C is fixed to the support column 10 with the stepped portion 21 and threaded portion 27 at the tip thereof protruding from the support flange 10a. In this case, the hole of the flange tOa and the retaining and rotating structure of the support member 20C are the same as those of the support member 20A shown in FIG. On the other hand, the fixing member 30A is shaped like a cap nut, has a threaded portion (female thread) 32A on its inner surface, and is screwed onto the threaded portion 27 of the support member 20C. A non-slip vertical groove is formed on the outer peripheral surface of the fixing member 30A.

The unit installation work in the second embodiment is similar to that in the first embodiment. That is, as shown in FIG. 11, first loosen the fixing member 30A a little and return it to the front. And unit)
