Description

[Detailed Description of the Invention] This invention relates to a packaging cushion for preventing damage to a ventilation fan, in which the head oil pan is composed of a ring part and a cylindrical electric motor part in the center thereof.

Conventionally, in order to prevent damage to this type of ventilation fan during transport, etc., the space between the outer packaging box and the interior ventilation fan was constructed in a predetermined shape using a combination of foamed resin molding or cardboard material. However, the former type, which is made of foamed resin, poses a well-known pollution problem when disposed of after use, and the latter type requires time and effort to cut and glue into the specified shape. There was a drawback.

This invention is designed to eliminate these drawbacks, and one embodiment of this invention will be described below.

That is, in the figure, A is the ventilation fan to be packaged, 1 is the head oil pan of this ventilation fan is a ring part, 2 is this oil pan is a cylindrical electric motor part protruding from the center of the ring part 1, and a is the oil pan. is a cardboard front buffer with an H-shaped cross section for holding the ring part 1;
b is a so-called rear shock absorber used in combination with the front shock absorber a to support the electric motor section 2 inside thereof; 3 is a ring portion 1 of the head oil pan of the ventilation fan A in its operating state; 4 is each shelf board part 3.3.
5 is the bottom wall between these two supporting legs 4, 4,
Reference numeral 6 denotes opposite side wall surfaces of the cylindrical motor section 2, whose central overlapping section 7 is fixed on the bottom wall section 5 in a folded state, and whose tips abut obliquely against the top edges of the respective support legs 4, 4. buffer plates 8 on both left and right sides for abutment against the supporting legs 4, 4, and iron parts 8 for separating both ends of the bottom wall 5 from the buffer plate 6 so as to leave the central overlapping part 7. , the dotted line indicated by 9 is the bending guide line during prescribed forming, B is the outer packaging box,
10 indicates its opening/closing lid.

As shown in FIG. 1, when using the proposed rear shock absorber which is formed by punching into a predetermined shape, a series of support legs 4, 4 are connected to the bottom wall 5 with the cut grooves 8 as a reference. Bend it into a U-shape and place a shelf section 3 at the top of both ends.
3 to project outward in the horizontal direction, and then the left and right buffer plates 6, 6 are each pulled inward, and the central overlapping portion 7 thereof is folded over and fixed onto the bottom wall portion 5.

Then, similarly, by using each of the cut grooves 8, both sides of the central overlapping part 7 are pulled up obliquely as shown in FIG. The assembly is completed in the state shown in the figure.

The cylindrical electric motor part 2 of the ventilation fan A is installed in the space surrounded by the dual leg parts 4, 4 formed in this way, the bottom wall part 5 between them, and the buffer plates 6 on both the left and right sides, as shown in FIG. The oil pan placed on both the above-mentioned shelf parts 3 and 3 is placed on the ring part 1 with the above-mentioned upper buffer body a, and the whole is inserted into the outer box B in the state shown in Fig. 4. be.

In this inserted state, each of the above-mentioned buffer plates 6 is interposed between the inner wall surface of the outer box B and the cylindrical electric motor part 2, and acts to absorb and alleviate shocks from inside and outside that occur on the iron part. It is.

Since the shock absorber of this invention is constructed as described above, the entire shock absorber can be constructed by simply bending a single punched plate, which allows for easy assembly when in use and when not in use. Not only is it extremely convenient to store in the unfolded state, but it also has practical benefits such as no pollution when disposed of.

[Brief explanation of drawings]

Figures 1 to 4 show an embodiment of the shock absorber for ventilation fan packaging of this invention. Figure 1 is a plan view of the expanded state after punching and forming, and Figure 2 is the assembled state when in use. FIG. 3 is a perspective view of a front shock absorber used with the shock absorber of this invention, and FIG. 4 is an open view showing a state in which a ventilation fan is accommodated in the outer box using each of the above shock absorbers. It is a top view in a lid|cover state. In addition, A in the figure is a ventilation fan, 1 is its head oil pan is a non-gang part,
2 is a cylindrical electric motor part, 3 is a shelf board for placing the upper 2+) ring part 1, 4 is a supporting leg of this shelf board, 5 is both supporting legs 4,
4, 6 is a buffer plate of the cylindrical electric motor section 2 with the center overlapping part 7 fixedly fixed on the bottom wall 5 on both sides thereof, and 8 is a buffer plate of this buffer plate. The cut groove provided for the rise mentioned above is shown. In other figures, the same reference numerals indicate the same parts.
