Description

[Detailed Description of the Invention] This invention relates to a head oil pan as a shock absorber for preventing damage to the ventilation fan caused by the ring part and the cylindrical electric motor part in the center.

Conventionally, in order to prevent damage to this type of ventilation fan during transportation, 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 bonded together. However, the former type made of foamed resin is known to cause pollution problems when disposed of after use, and the latter type takes time and effort to cut into the specified shape and cut into small pieces. There were drawbacks such as.

This invention is designed to eliminate these drawbacks, and one embodiment of this invention will be described below with reference to FIGS. 1 to 4.

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. denotes an H-shaped cardboard front shock absorber for holding the ring portion 1;
Reference numeral 3 indicates the shelf plate portions on both sides of the head oil pan of the ventilation fan A on which the ring portion 1 is placed in its operating condition; 4 indicates the vertical supporting legs of the respective shelf plate portions 3; 5 indicates the leg portions 4, The bottom wall portion between 4 and 6 is separated from the leg portions 4, 4 and the bottom wall portion 5 by cut grooves 7 on both sides thereof, and the free ends 6a and 6b thereof, which are divided into two at the center, are assembled. The shape-retaining buffer plates on both the left and right sides are lowered obliquely toward the bottom wall 5 in the above-mentioned state, and are combined in a crossed state at the central engagement groove 6C as shown in FIG. In this state, it abuts against the opposite side wall surfaces of the cylindrical motor section 2.

Reference numeral 8 indicates a separation groove provided at the center of each of the shape-retaining buffer plates 6, dotted lines 9 indicate bending guide lines during predetermined molding, and reference numeral B indicates the opening/closing lid of the outer packaging box 10.

When using the rear proposed shock absorber, which is formed by punching into a predetermined shape as shown in FIG. 7, first remove U regardless of the shape-retaining buffer plates 6 and 6 on both sides.
It is bent into a letter shape, and the above-mentioned shelf board parts 3, 3 are made to protrude outward in the horizontal direction at the upper portions of both ends.

After that, the free ends 6 a and 6 b of the shape-retaining buffer plates 6 and 6 on both the left and right sides, which protrude inward from the shelf board parts 3 and 3, respectively, are moved toward the bottom wall part 5. By lowering the shock absorber diagonally and intersecting with each other through the central engagement grooves 6C, the entire shock absorber is assembled as shown in FIG.

In the space surrounded by the legs 4, 4 formed in this way, the bottom wall 5 between them, and the shape-retaining buffer plates 6, 6 on the other side,
Place the cylindrical electric motor part 2 of the ventilation fan A as shown in Fig. 4,
The oil pan placed on both the above-mentioned shelf parts 3, 3 is designed by covering the ring part 1 with the above-mentioned upper buffer body a, and inserting the whole into the outer box B in the state shown in Fig. 4. .

In this inserted state, each of the buffer plates 6 is interposed between the inner wall surface of the outer box B and the cylindrical motor part 2 in a state where the entire shape is maintained, so that the shocks generated on the iron part from inside and outside are absorbed. This acts to ensure absorption and relaxation.

Since the shock absorber of this invention is constructed as described above, the entire shock absorber can be constructed by simply folding and assembling a single punched plate. Not only is it extremely convenient to store the device in its unfolded state, but its disposal is also non-polluting.

Furthermore, since the proposed shock absorber maintains its predetermined shape in the assembled state, the shock absorbing effect is even more reliable when used inside the outer box.

[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 ventilation fan housed in the outer box using each of the above shock absorbers. It is a top view in a lid|cover state. In the figure, A is the ventilation fan, 1 is the head oil pan is the ring part, and 2 is the ventilation fan.
The cylindrical motor part 3 is a shelf plate part for mounting the ring part 1, and 4
5 is the bottom wall between the inner legs 4, 4, and 6 is the free end portion 6a, 6b of the shelf board, which is joined to each other by the central retaining groove 6C. Both shape-retaining buffer plates 7 on the other side are brought into contact with each other, and reference numeral 7 indicates a cutting groove for separating each of these shape-retaining buffer plates 6. In other figures, the same reference numerals indicate the same parts.
