Description

[Detailed description of the invention] This invention is a cushioning material for packaging ventilation fans to prevent damage that may occur during storage and transportation.

Conventionally, in order to prevent damage to the ventilation fan housed in the outer box, the cushioning material that is filled between the outer box and the ventilation fan is a molded product made of foamed resin or a cardboard board cut to a specified size and then glued together. Those combined into a predetermined shape were used.

However, with such conventional cushioning materials, for example, those made of foamed resin cause well-known pollution when disposed of after use, and those made of cardboard are expensive to manufacture due to their bottom shape and combination work. There were drawbacks.

This invention is aimed at eliminating the above-mentioned drawbacks, and one embodiment of this invention will be described below.

That is, in the figure, 1, as is well known, is a large-diameter front oil pan, which is a ventilation fan that is connected to a ring part A and a small-diameter cylindrical motor part B at the rear of the ring part, and 2 is a single molded folded board made of cardboard. 1 is a single-fold front half holder that covers the ring part A from the front, and is composed of parts 2a to 2e shown below.

First, 2a in the figure shows the assembled state, and the oil pan is a top plate part for holding down the front surface that abuts against the front surface of ring part A, and 2b shows the oil pans formed in series on both sides of this top plate part for holding down the sides of ring part A. The end plates 2C are protruding protrusions provided on the outer edge of each end plate 2b, and 2d are cut protrusions protruding from each end plate 2b so as to be located on the opposite side of the protrusions 2C. The pieces 2e are notches provided on both outer edges of the top plate portion 2a for forming these tension pieces 2d, and these are simultaneously formed by punching out a single plate such as cardboard paper.

Reference numeral 3 denotes a single-folded second half holder made of a single folded cardboard plate that accommodates the cylindrical electric motor part B in the assembled state. The left and right opposing double concave walls 3C on the inside of the center and the upper and lower retaining walls 3f on the outside are arranged on each of the flanges 3b so that the U-shaped horizontal flanges 3b on which the motor parts are placed and the cylindrical electric motor part B are sandwiched between them. A locking hole 3e is formed by notches 3d on four sides, and a locking hole 3e into which an overhanging piece 2C provided on the front half holder 2 is inserted in a connected state is provided at the center of each of the collar portions 3b.

4 is an outer box in which the ventilation fan 1 placed between the first half holder 2 and the second half holder 3 is stored, and the dotted lines on the map indicate the bending lines for forming each wall in the corresponding part. .

FIG. 3 is a plan view showing a state in which the ventilation fan 1 is housed in the outer box 4 using the first half holder 2 and the second half holder 3 configured as described above, with each holder and the outer box cut away. For the oil pan of the ventilation fan 1 supported by the second half holder 3, cover the ring part A with the first half holder 2, and
By fitting C into the locking hole 3e provided in the flange 3b of the rear holder 3, the ventilation fan 1 can be attached to the front and rear holders 2, 3.
Place it in the outer box 4 while holding it between them, and with the tension piece 2d of the first half holder 2 and the flange 3b of the second half holder 3 stretched inside the outer box 4, attach the outer box 4 with adhesive tape or the like. This is to complete the packaging by sealing it.

As mentioned above, in the shock absorber of this invention, both the front and rear holders are made of a single piece of cardboard, etc.
Disposal after use is easy, and the shape of the shock absorber itself is made up of a single folded sheet of plate-shaped molding, which reduces material costs and manufacturing costs. In addition, the space required for storage in the unfolded state is extremely small, and furthermore, by integrating the ventilation fan with the front and rear holders in advance, automatic packaging of the entire product becomes possible.

[Brief explanation of drawings]

The figures show one embodiment of the shock absorber of this invention. Figure 1 is a developed plan view of the rear half holder, Figure 2 A is a perspective view of the front half holder, the opening is a developed plan view, and Figure 3 is the outside. FIG. 3 is a plan view showing a state in which the ventilation fan is housed in the box by cutting the center section of the front and rear holders and the outer box. In the figure, 2 is the front half holder, 2a is its top plate, 2b is the front plate, 2C is an overhanging piece, 2d is a cut-and-raised piece, and 3
is the second half of the holder, 3a is its flange, 3C is the concave wall, 3e
3f is a locking hole, 3f is an upper and lower holding wall, A is a ring portion of the oil pan of the ventilation fan 1, B is a cylindrical electric motor portion, and 4 is an outer box. In other figures, the same reference numerals indicate the same or corresponding parts.
