The stopper part 45 by the lancing processing shown only in FIG. 3 is provided in this protrusion side edge part, and the engagement part 44 is prevented from escaping from the engagement long hole 23,34.

In addition, as described above, the position of the first auxiliary attachment means 30 is opposed to the concave recessed portion 12 of the main frame 11, and the long hole 34 for engaging the first auxiliary attachment means is provided. Since the engaging portion 44 of the second auxiliary attachment means 40 protrudes, the engaging portion 44 is in the recessed portion 12, and the body frame 11 in the assembled state and in the assembled state. Do not touch against

Next, the attaching operation | work to the ceiling board 4 of the ventilation fan attachment apparatus comprised in this way is demonstrated.

Initially, the exhaust frame 20 is prepared, and the first auxiliary attaching means 30 is attached to the left and right side portions. In other words, the upper bent portion 31 of the attachment means 30 may be hooked to the upper end of the exhaust frame 20, and the lower pole portion 32 may be inserted into the exhaust frame hole 33. In this state, the engaging long hole 34 of the first auxiliary attaching means 30 accurately faces the engaging long hole 23 of the exhaust frame 20.

Next, the engaging portion 44 of the second auxiliary attaching means 40 is inserted through each of the engaging long holes 23 and 34 to protrude the tip into the exhaust frame 20. At this time, the stopper portion 45 does not stand on the engagement portion 44 side, but is inserted and passed through, and then the engagement portion 44 smoothly inserts through the elongated holes 23 and 34 for engagement.

After attaching the first auxiliary attaching means 30 and the second auxiliary attaching means 40 to the exhaust frame 20, the exhaust frame 20 is opposed to the attachment opening 5 of the ceiling plate 4. Insert into the attachment opening from the upper end of the exhaust frame.

However, the engaging portion 44 of the second auxiliary attachment means 40 is pulled to protrude into the exhaust frame 20 as much as possible. Accordingly, the second auxiliary attachment means 40 is almost in close contact with the exhaust frame 20 through the first auxiliary attachment means 30 from the upper end thereof to the upper end of the accommodation part 43, and only the accommodation part 43 protrudes at an angle. do.

When the exhaust frame 20 is vertically pushed up as it is, the exhaust port body 2 comes into contact with the periphery of the attachment opening 5 of the ceiling plate 4, and it is obstructed to pass. It is the same as the conventional thing that the exhaust port 2 passes through the opening part 5 without pushing and pushing up.

When the lower flange portion 21 of the exhaust frame 20 abuts the ceiling plate 4, a hand is inserted into the exhaust frame 20 to raise the stopper portion 45 of the second auxiliary attachment means 40. Then, the engaging portion 44 is pushed outward of the tip. The stopper portion 45 abuts against the inner side surface of the exhaust frame 20 and restricts the engagement portion 44 from protruding further. As a result, the second auxiliary attachment means 40 is in an oblique position.

In addition, this operation requires the operator to hold the exhaust frame 20 with one hand, and to raise the stopper portion 45 and push outward the front end of the engaging portion 44 with one hand. Compared with the work using the tool, it is extremely simple and does not impair workability.

When the above work is completed, the worker may remove his hand from the exhaust frame 20 and the second auxiliary attachment means 40. One end is dropped by the weight of the exhaust frame 20 itself, but since the second auxiliary attachment means 40 is in an oblique position and the receiving portion 43 protrudes outward, the receiving end is placed on the ceiling plate 4. On top of that, an upper engagement portion 41 is inserted into each of the engagement holes 23 and 34.

That is, the fall amount is extremely small because the second auxiliary attachment means 40 directly regulates the fall of the exhaust frame 20. The exhaust frame 20 is attached while the ceiling plate 4 is sandwiched between the flange portion 21 of the exhaust frame 20 and the receiving portion 43 of the second auxiliary attachment means 40.

However, since the receiving portion 43 of the second auxiliary attachment means 40 protrudes outward, it is caught by the circumferential edge of the attachment opening 5, and the exhaust frame 20 is almost forcibly inserted. Therefore, in particular, as shown in FIG. 3, both side surface portions 20b of the exhaust frame 20 tend to elastically deform and fall from the upper side to the inner side.

Next, the main frame 11 having the ventilation fan 1 or the like attached to the exhaust frame 20 is inserted from below. Since both sides of the exhaust frame 20b fall inward, the main frame 11 is also forcibly inserted to push the exhaust frame both side portions 20b outward. In the state in which the main frame 11 is attached, the lower accommodating portion 43 and the upper engaging portion 41 of the second auxiliary attaching means 40 attach the exhaust frame 20 more firmly.

At the position where the flange portion 6 of the body frame 11 completely covers the flange portion 21 of the exhaust frame 30 and abuts against the ceiling plate 4, the protrusion 13 hangs on the exhaust frame 20. The fitting recess 22 is engaged with the fitting recess 22. Therefore, the worker does not fall even if he takes his hand from the main frame 11.

In this way, all the attachment work to the ceiling plate 4 of a ventilation fan attachment apparatus is complete | finished. As a result, it is not necessary to squeeze the frame of the wood to attach the ventilation fan attachment device, and it can be easily installed without tools such as wood screws or tools such as a screwdriver.

The engaging portion 44A of the auxiliary attaching means 40A is characterized.

That is, the width size is large so that only the upper part of a pair of engagement long hole 34B may protrude inwardly from each other compared with the lower part. The width of the upper part of the engaging long hole 34B is "A", and the mutual gap size of the long holes is "B".

On the other hand, the upper end of the engaging portion 44A of the second auxiliary attachment means 40A is bent so as to face the inner side here, and the width of the bent portion 46 is set to "A", and the bent portion is formed. (46) Set the end-to-end mutual spacing size to “B '” and set the size relations to A> A', B> B '.

Since the above conditions are provided, when the engaging portion 44A of the second auxiliary attachment means 40A is inserted into the engaging long hole 34B, the bent portions 46 at the upper end of the engaging portion 44A are mutually separated. Slightly widened to the left and right, from "B '" to more than "B". Once the engaging portion 44A is inserted into the engaging long hole 34B, the bent portion 46 mutual gap size returns to the original “B '”.

Accordingly, when the second auxiliary attachment means 40A moves along the engagement long hole 34B, the portion between the bent portions 46 is moved larger than the size B between the upper ends of the long holes. The fall prevention in the engagement long hole 34B of 40A is made reliably, and workability is favorable.
