DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shock absorber which is installed inside a packaging box and protects articles stored in the packaging box from impacts received from a lower portion of the packaging box due to dropping or the like.

[0002]

2. Description of the Related Art As a conventional buffer, for example, a foamed styrene resin molded in a block shape is known. The cushioning body is interposed, for example, between the inner wall of the packaging box and the articles stored in the packaging box, thereby supporting the articles in the packaging box and dropping due to the buffering action of the styrene foam resin. Protect the goods by absorbing the impact of However, since the buffer is a block made of styrene foam resin, there is a disadvantage that the block itself cannot flexibly buckle and absorb a relatively soft impact, such as absorbing the impact.

Further, in order to facilitate incineration and recycling, etc., a plurality of corrugated paperboards are stacked between the article and the packaging box, and a cushioning material formed in a thick plate shape is interposed between the articles and the packaging box. There is also known an article which protects an article from an impact, but also does not buckle more flexibly than a styrofoam resin block and is relatively soft and difficult to absorb the impact.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a shock-absorbing body which can be formed by using a paperboard or the like which can be easily incinerated or recycled, and which can obtain a flexible shock absorbing force. The purpose is to do.

[0005]

In order to achieve the above object, a first aspect of the present invention is a buffer which is installed on a bottom plate inside a packaging box and protects articles placed thereon. A mounting plate having a shape corresponding to the bottom plate of the packaging box, a pair of frame plates vertically continuous from at least both side edges of the mounting plate, and a mounting plate surrounded by the frame plate. A grid-like body provided below and supporting the mounting plate with a predetermined gap from the bottom plate, and the grid-like body is made of flexible plate materials arranged in parallel between the frame plates. A plurality of vertical buffer plates,
A plurality of horizontal buffer plates made of a flexible plate material arranged in parallel with each other in a direction intersecting with the vertical buffer plate, wherein the vertical buffer plate has an upper edge with a gap from the mounting plate and a lower edge with a gap. A plurality of first vertical shock-absorbing plates projecting downward from the frame plate so as to abut against the bottom plate of the packaging box; The horizontal shock absorbing plate has a parallel upper edge that is inclined in a direction in which an upper end edge is gradually separated from the mounting plate and a lower end edge is inclined in a direction that gradually approaches the bottom plate of the packaging box. A first horizontal shock-absorbing plate formed into a shape and having one end fixed to one side surface of the first vertical shock-absorbing plate;
A second horizontal shock-absorbing plate formed so as to have the same shape as the first horizontal shock-absorbing plate when rotated by 0 degrees, and having one end fixed to the other side surface of the first vertical shock-absorbing plate; The first horizontal shock absorbing plate located between a plate and the first vertical shock absorbing plate,
The other side end is fixed to the frame plate, and the first horizontal buffer plate located between the first vertical buffer plate and the second vertical buffer plate has the other side end fixed to the second vertical buffer plate. The second horizontal shock absorbing plate located between the frame plate and the first vertical shock absorbing plate has another end fixed to the frame plate, and the first vertical shock absorbing plate and the second vertical shock absorbing plate are fixed to each other. And the other side end of the second horizontal buffer plate located between the second horizontal buffer plate is fixed to the second vertical buffer plate.

[0006] In the first aspect of the present invention, it is preferable that the horizontal buffer plate is provided to be inclined from the mounting plate toward the bottom plate of the packaging box.

According to a second aspect of the present invention, the lattice members according to the first aspect, in which the horizontal cushioning plates are inclined from the mounting plate toward the bottom plate of the packaging box, are arranged side by side in a pair. The grid on the right side is characterized by being formed into the same shape when the grid on the left side is rotated 180 degrees about the vertical direction as an axis.

In a third aspect of the present invention, the lattice-like body of the first aspect is provided in a pair of upper and lower layers, and the lower lattice-like body is arranged such that the upper lattice-like body is orthogonal to the vertical buffer plate. It is characterized in that it is formed in the same shape when rotated 180 degrees around a horizontal direction as an axis.

[0009] In the third aspect of the present invention, it is preferable that each of the horizontal buffer plates of both the grid-like bodies is provided to be inclined from the mounting plate toward the bottom plate of the packaging box.

[0010]

According to the first aspect of the present invention, when the article is placed on the mounting plate in the packaging box, a load is applied to the mounting plate by an impact received from a lower portion of the packaging box due to a drop or the like. First, the mounting plate is pushed down. by this,
The mounting plate and the bottom plate of the packaging box approach each other, the upper edge of the first vertical buffer plate is moved in a direction of contacting the mounting plate, and the lower edge of the second vertical buffer plate contacts the bottom plate of the packaging box. Go to At this time, the lateral shock absorbing plate is twisted and deformed with a restoring force to absorb the impact. Further, with the deformation of the horizontal shock absorbing plate, the vertical shock absorbing plate is also flexibly deformed with a restoring force and flexibly absorbs an impact.

[0011] In the first aspect, by providing the horizontal buffer plate inclined from the mounting plate toward the bottom plate of the packaging box,
The horizontal buffer plate is bent according to the direction of its inclination, and the amount of bending is smaller than when the horizontal buffer plate is provided vertically. As a result, it is possible to prevent the lateral buffer plate from being damaged and to obtain a relatively large restoring force.

According to a second aspect of the present invention, the protection of the article by the buffering action of the horizontal and vertical cushioning plates when a load is applied to the mounting plate is the same as the first aspect described above. . In the second aspect, a lattice-like body located on the left side and a lattice-like body located on the right side of a shape obtained by rotating the lattice-like body by 180 degrees around the vertical direction are arranged side by side as a pair of left and right sides. . The horizontal buffer plate of the lattice-shaped body located on the left side is provided between the frame plate, the first vertical buffer plate, and the second vertical buffer plate, and is inclined in the same direction between the mounting plate and the bottom plate of the packaging box. Have been. When the horizontal shock absorbing plate absorbs the impact as described above, the mounting plate approaches the bottom plate of the packaging box so as to be pushed down obliquely under the influence of the inclination of the horizontal shock absorbing plate. On the other hand, the grid-like body located on the right side is provided to be inclined in the direction opposite to the lateral buffer plate of the grid-like body located on the left side. As a result, when the horizontal shock absorbing plate absorbs the impact as described above, the horizontal shock absorbing plate is deformed so as to push down the mounting plate in a direction opposite to the lateral shock absorbing plate of the lattice-like body located on the left side. Therefore, the deformation direction of the lateral buffer plate of the lattice-like body located on the left side,
The direction of deformation of the horizontal buffer plate of the lattice-shaped body located on the right side is opposite to that of the horizontal buffer plate, and the effect of the inclination of the horizontal buffer plate is cancelled, and the mounting plate is pushed down while maintaining a horizontal state.

According to the third aspect of the present invention, in a state where the article is placed on the placing plate installed in the packaging box, the article is placed on the placing plate by an impact received from a lower portion of the packaging box by dropping or the like. When a load is applied, in the same manner as in the first embodiment, the upper and lower horizontal buffer plates are torsionally deformed with a restoring force to absorb shocks, and as each horizontal buffer plate is deformed, each vertical buffer plate is deformed. It also bends and deforms with a restoring force to absorb the impact. At this time, in particular, in the shock absorber of the third mode, the mounting plate is not only flexible, but also the peripheral edge is supported on the bottom plate of the packaging box by the frame plate. For this reason, even if the load of the article by an impact is applied to the mounting plate, the mounting plate is deformed so that the center portion thereof is depressed without being entirely lowered toward the bottom plate of the packaging box. On the other hand, between the mounting plate and the bottom plate of the packaging box, the lattice-shaped members are provided one above the other, and each buffer plate of the upper lattice-shaped member and each buffer plate of the lower lattice-shaped member are provided. Since each of them is deformed separately, higher flexibility can be obtained as compared with the case where a single lattice-like body is provided. Therefore, the upper and lower lattice members can flexibly support the depression of the mounting plate and obtain a sufficient buffering action at the central portion of the mounting plate.

[0014] In the third aspect, the horizontal buffer plate is provided so as to be inclined from the mounting plate toward the bottom plate of the packaging box.
Each horizontal buffer plate of the upper and lower lattice members is bent according to the direction of its inclination, and the amount of bending is made smaller than that in the case of bending in the vertical direction to obtain a sufficient restoring force without lowering the buffering action.

At this time, by providing the horizontal buffer plates inclining from the mounting plate toward the bottom plate of the packaging box, each horizontal buffer plate is bent according to the direction of the inclination, thereby reducing the buffering effect. A sufficient restoring force can be obtained without any.

Further, in the shock absorber of the present invention, when the article is placed on the mounting plate installed in the packaging box, a load is applied to the mounting plate by an impact received from below the packaging box when the article falls. When the mounting plate has flexibility, the periphery of the mounting plate is supported by a frame plate, so by providing the pair of lattice-like bodies vertically stacked, especially the mounting plate The article can be reliably protected by obtaining higher flexibility in the central portion of the article.
