Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shock absorbing device for protecting a plate-like article which may be damaged or deformed by an impact applied during transportation from an impact force.

[0002]

2. Description of the Related Art Relatively expensive articles such as large mirrors and plate-shaped crafts must not be damaged or deformed during distribution.
For this reason, it is general that the above-mentioned articles are individually housed in an outer box by contacting a cushioning material on both front and back surfaces and then distributed in this state.

The cushioning material is formed by adhering a synthetic resin foam, which is foamed at an appropriate ratio, to a board such as corrugated board.
By contacting the foam with the front and back surfaces of a plate-shaped article, an impact from the outside is absorbed to protect the article. Such a cushioning material can set the expansion ratio and shape with a high degree of freedom according to the weight and shape of the packaged object, and can be used for cushioning many articles other than plate-like packaged objects. It is used as a material.

[0004]

Generally, the cushioning material in which the foam is attached to a mount is constructed so as to correspond to the intended article to be cushioned. Therefore, for example, even in the case of plate-shaped articles having the same plate thickness, if the sizes are different, different cushioning materials will be used, and as the number of product types increases, the types of cushioning materials to be managed increase, There is a problem that the management cost increases.

Further, recently, from the viewpoint of waste pollution, there is a problem that if an accessory made of a synthetic resin is provided, delivery is refused unless the recovery route of the accessory is established. Therefore, there is a demand for the development of a buffer that can protect the packaged object from impact without causing waste pollution.

The object of the present invention is to protect a packaged object from an impact that may act on the packaged object in the process of circulating the packaged object, and to eliminate the possibility of causing waste pollution. It is to provide a shock absorber that can be applied regardless of the increase in types.

[0007]

In order to solve the above problems, a shock absorbing device according to the present invention is a shock absorbing device which is mounted on the peripheral edge of a plate-shaped packaged object and is arranged between the package and the outer box. ,
A support member having a support groove into which the plate-shaped packaged object is fitted in the thickness direction, and a contact member that is fitted into the groove and contacts the end surface of the plate-shaped packaged object It is a thing.

In the above-mentioned shock absorber, the supporting member has a bottom piece that comes into contact with the outer box, a standing piece that is connected to the bottom piece, and a bending piece that is connected to the standing piece. A support groove that fits the packaged object in the thickness direction is formed across the pieces, and the contact member is formed by bending a blank having at least five pieces so that a side in a direction intersecting with the end surface of the packaged object is formed. It has a quadrangular cross section in which at least three pieces are overlapped, and is formed by forming an engaging groove for engaging these plates at a position facing the rising piece and the bending piece of the supporting member. preferable.

[0009]

According to the above-mentioned shock absorbing device, the contact member is fitted into the support groove formed in the support member, and the peripheral edge of the plate-shaped packaged object is fitted into the groove, and is housed in the outer box in this state. As a result, the packaged object can be packaged while being floated from each side of the outer box. Therefore, even if an impact force acts on the outer box in the distribution process, the impact force does not directly act on the packaged object, and the packaged object can be protected from the impact force.

Further, the support member is constituted by a bottom piece, an upright piece, and a bent piece, and a support groove is formed across the upright piece and the bent piece to form a support member, and at least one side has a quadrangular shape. A contact member is formed by forming an engaging groove that has a cross section and faces the upright piece and the bending piece of the support member and that engages these plates, and the contact member is fitted into the support groove and engaged. By locking the mating groove to the upright piece and the bent piece, a shock absorber composed of an assembly can be constructed.

Therefore, if the object to be packaged is plate-shaped, it can be applied regardless of weight or size. That is, by arranging and mounting a desired number of shock absorbers on the periphery of the packaged object, the packaged object can be buffered.

It is possible to prevent the impact force applied to the outer box C from directly acting on the packaged object B by protecting the outer box C from the outer box C for protection.

The support member 1 is, as shown in FIG.
The bottom piece 1a is in contact with the inner surface of the outer casing C, the standing piece 1b is connected to the bottom piece 1a, and the bending piece 1c is connected to the standing piece 1b. The support groove 3 is formed over 1c. The support member 1 has a bottomed M by bending the bending piece 1c toward the bottom piece 1a while raising the upright piece 1b with the bottom piece 1a as a reference.
A support groove 3 is formed in a letter shape and connects the standing piece 1b and the bending piece 1c to each other and extends along the longitudinal direction of the bottom piece 1a.

The dimensions of the width of the support member 1, the length of the bottom piece 1a, the length of the standing piece 1b, etc. are not particularly limited, and the weight and size of the package B and the package B can be arranged. It can be appropriately set according to the conditions such as the number of shock absorbers A.

The contact member 2 is, as shown in FIG.
It is formed to have at least five pieces 2a to 2e, and is configured such that the outermost two pieces 2a and 2e are bent so as to overlap with each other to have a rectangular cross section. In the present embodiment, the pieces 2a, 2c, 2e correspond to the long sides of the rectangular cross section, and the pieces 2b, 2d correspond to the short sides. Further, each of the pieces 2a, 2c and 2e is formed with an engagement groove 4 which engages with the standing piece 1b of the support member 1 and an engagement groove 5 which engages with the bending piece 1c.

The pieces 2a, 2c, 2e have a function of buffering the impact force generated when the packaged object B falls in a direction parallel to the surface of the packaged object B, and have sufficient buffering performance. It is necessary to stack at least three pieces in order to obtain. When the weight of the packaged object B is large, a piece similar to the piece 2e is added to the free end side of the piece 2a to bend the piece 2a into a rectangular shape, thereby forming four pieces in which long sides of rectangular cross sections are overlapped or It is preferable to be composed of four or more pieces.

The support groove 3 is formed to have a size equal to or slightly smaller than the thickness of the package B. Therefore, by fitting the peripheral edge of the packaged object B into the support groove 3, the shock absorber A can be firmly attached to the packaged object B, and the shock absorber A does not move during transportation.

A procedure for constructing the shock absorber A by the support member 1 and the contact member 2 will be described. First, the standing piece 1b and the bending piece 1c of the supporting member 1 are bent to form the bottom piece 1
Each piece 2a of the contact member 2 is formed in an M shape having a as a bottom.
2e is bent to form a rectangular tube. The contact member 2 is fitted into the support groove 3 of the support member 1, and the engaging grooves 4 and 5 are locked to the upright piece 1b and the bending piece 1c. This makes it possible to configure the shock absorber A shown in FIG.
