Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a shock absorbing device used during packaging.

In television receivers and the like in which a heavy cathode ray tube is disposed on the front side of the product, the center of gravity of the product is often shifted toward the front side. When a product with such an eccentric center of gravity is packaged, the longer it takes after packaging, the more the cushioning material that receives the center of gravity of the product will be crushed or deformed. Therefore, the product is placed in an inclined position, and as a result, a product with an eccentric center of gravity has the disadvantage that it tends to fall toward the center of gravity, but when the inclination due to the deformation of the cushioning material is taken into account, this tendency becomes even more pronounced, making it unstable. It was packed in a perfect condition. This condition appears particularly when the number of stacks is increased by oriented the products in the same direction, causing the products to not be stacked in the same direction, and the products must be stacked with care, with the eccentric center of gravity facing alternately.

Therefore, as a countermeasure for the above-mentioned drawbacks, as a shock absorbing device for holding the lower side of a product with an eccentric center of gravity such as a conventional television receiver, it is necessary to increase the receiving area of the cushioning material on the center of gravity side, or to use a different one. The above drawbacks were addressed by adding and reinforcing parts.

However, the configuration in which the receiving area is widened has the disadvantage that a large amount of cushioning material is used. Additionally, when using a molding machine to manufacture shock absorbers, the effective area of the mold is determined by the machine, so the number of molds that can be molded at once decreases, making it impossible to mold multiple pieces or reducing the number of molds. This method has drawbacks, in other words, it leads to an increase in product cost. Furthermore, when additional parts are added, the product cost similarly increases and work is required to assemble and fix the separate parts to the shock absorber by some method.

The object of the present invention is to solve the above-mentioned drawbacks and to provide a shock absorbing device that can easily pack products with an unbalanced center of gravity.

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. FIG. 1 is an exploded perspective view showing a combination of a shock absorber and a television receiver according to the present invention. FIG. 2 is an enlarged perspective view of a part of the shock absorber shown in FIG. 1 (the right side part in the figure). The shock absorber 5 of the present invention is made of polystyrene foam and has a substantially prismatic outer shape. Further, a recessed portion is formed in a portion of the prism, into which a portion of the television receiver centered around the lower edge 2 of the side surface is mounted. Therefore, the bottom, side, front, and bottom of the television receiver are placed in this recess.
The product is placed in contact with a part of the back surface.

The bottom surface of the television receiver is brought into contact with the bottom surface of this concave portion, forming a product bottom receiving portion 6. This product bottom receiving portion 6 is provided with a sloped surface that decreases from the mounting side of the cathode ray tube 3 disposed in the front of the television receiver 1 toward the back. This inclined surface is formed by changing the thickness of the bottom receiving part of the product. That is, when the height of the front part of the shock absorber on which the cathode ray tube is attached is a, and the height of the rear part is b, a slope is provided such that a>b. Furthermore, a protrusion 7 which can be crushed relatively easily is provided integrally with the bottom receiving part 6 at a position on the back side of the product bottom receiving part 6 and in contact with the bottom surface of the television receiver 1. If the height of this protrusion 7 is c, the height relationship between a, b, and c is approximately c
The relationship is +b=a.

A case in which the television receiver 1 is packed using the shock absorber 5 having the above structure will be explained with reference to FIGS. 3 and 4. Fig. 3 is a cross-sectional view showing a television receiver packed using the shock absorbing device of the present invention, and Fig. 4 is a cross-sectional view showing a partially deformed state of the device shown in Fig. 3. be.

The bottom receiver 6 is provided with a protrusion 7 at the same time as the slope, and as mentioned above, the height relationship is c+b=a, so that the television receiver 1 is stable without tilting as shown in FIG. It is possible to place it on the shock absorber 5 in this state. However, the height c of the protrusion 7 is relatively easy to crush and is provided over a small area, so as shown in Figure 4, it is almost deformed by the impact and vibration load caused by movement during and after packaging. .

Also, after packaging, since the center of gravity is on the front side of the television receiver 1, the front side (a) of the shock absorber 5 deforms more and the back side (b) deforms less, but the height of each is in the relationship a>b. Since the front part is thick, the height of the front view and the rear part after deformation is as follows: Let the height of the front part after deformation be a', and the height of the back part after deformation be b'.
Since a'=b', the shock absorber 5 can be used in a stable state after deformation.

Furthermore, the lower shock absorber 5 of the present invention is used in combination with the upper shock absorber 10, which has conventionally been used on the ceiling side of products. 1) are combined and stored in a box-shaped cardboard box 11 for use.

As explained above, according to the present invention, an inclined surface and a protrusion are formed on the lower side of this inclined surface on the cushioning material receiving surface of a product whose center of gravity is offset, and the center of gravity of the product is placed on the higher side of the inclined surface. did. As a result, since the amount of deformation of the cushioning material on the center of gravity side is large, the inclined surface becomes a horizontal surface, and it was possible to obtain a shock absorbing device that can hold a product with a shifted center of gravity perpendicular to the floor surface.

Therefore, even if the number of stacked products is increased by aligning products whose centers of gravity are offset in the same direction, the products can be stored in a stable condition without tilting toward the center of gravity or falling over, which is a great effect. I was able to do that.
