Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improvement of a shock absorber used when packing electrical equipment, gas equipment, and the like.
[0002]
[Prior art]
In general, when packing electrical equipment and gas equipment, etc., together with cushioning materials to protect the equipment from moving inside the cardboard box, and protecting it from impact caused by dropping or vibration, external impact, etc. Housed in a cardboard box, the equipment is protected during transportation and storage.
[0003]
As a conventional cushioning material, a material obtained by molding foamed plastic such as polystyrene foam is widely used. Foamed plastic is a material with an excellent buffering function for protecting the device, and can be easily molded in accordance with the shape of various devices, and has the advantage of increasing the efficiency of storage in the packaging material.
[0004]
[Problems to be solved by the invention]
However, although the cushioning material made of foamed plastic has excellent properties, the material itself has various problems in terms of processing after being used as the cushioning material. For example, because the collection route has not been developed, it is disposed of as household waste and has become a major social problem. In connection with this, handling takes time at the time of collection, and the collection cost increases. In addition, incineration and disposal requires high energy, so an incinerator must be maintained. In addition, since the cushioning material made of foamed plastic itself is extremely bulky, the transportation efficiency is low, the transportation cost is high, and a large space is required for the storage space.
[0005]
[Means for Solving the Problems]
Therefore, the present inventor has achieved the present invention as a result of diligent research in view of the above problems, and the feature is that from one side of the bottom plate, the side plate, the top plate and the inscribed plate The cylindrical body forming pieces are extended to connect two cylindrical bodies having different heights, and the upper surface plate of one cylindrical body and the inscribed plate of the other cylindrical body protruding from the upper surface plate are stored. Covering at least part of the openings at both ends of each cylinder and part of both ends of the top plate of each cylinder on the support used as the support surface of the body, respectively, provided on both ends of the top plate of each cylinder Each cylindrical body is connected and fixed by engaging a U-shaped frame body comprising an outer plate, a width plate, and an inner plate having insertion pieces inserted into the insertion grooves, and one of the cylinders. The inner plate protruding from the upper surface plate of the body is used as the support surface of the storage body.
[0006]
Alternatively, two cylindrical bodies having different heights are provided by extending cylinder-forming pieces each including a side plate, a top plate, and an inscribed plate from one side of the bottom plate, and the top of one cylinder is connected. Two support bodies having a structure in which the inscribed plate of the other cylindrical body protruding from the top plate and the top plate is used as a support surface of the storage body, and the two support bodies in a state where the one cylindrical body is opposed to each other Covers and fixes the openings on both ends of each cylinder and part of both ends of the top plate of each cylinder from both sides of the mounting plate on which each support is placed, and the top plate of each cylinder An outer plate having insertion pieces to be inserted into insertion grooves respectively provided on both ends, a width plate, and a tray in which an inner plate is sequentially extended, and one of the cylinders of the tray The inner plate protruding from the upper plate is used as a support surface of the storage body.
[0007]
Here, the term “support” as used in this specification refers to two different heights obtained by extending cylinder-forming pieces each consisting of a side plate, a top plate and an inscribed plate from one side of the bottom plate. With a structure in which cylinders are connected in series, the upper and lower plates of the lower cylinder and the inboard plate of the higher cylinder protruding from the upper plate are stored by varying the height of each cylinder. The body support surface. In addition, insertion grooves for inserting and fixing a frame body and a tray insertion piece, which will be described later, are respectively provided on both end sides of the upper surface plate of each cylindrical body. The cylindrical body forming piece may be provided with a superposed piece superposed on the bottom plate from the inscribed plate. In the case where the superposed piece is provided, a part thereof may be bent at a substantially right angle so that the end face comes into contact with the side plate, the top plate and the inscribed plate.
[0008]
The “frame” is used to connect and fix the cylinders of the support, and an outer plate and a width plate provided with insertion pieces that are inserted into insertion grooves respectively provided on both ends of the upper surface plate of each cylinder. It is composed of an inner plate. The inner plate is provided with the insertion piece at the tip thereof, and a portion protruding from the upper surface plate of the lower cylindrical body of the support body becomes a support surface of the storage body. The frame may be separate from the support or may be formed integrally.
[0009]
When the frame body is separated from the support body, an insertion piece is extended from the outer plate, and is inserted into and engaged with openings at both ends of each cylindrical body of the support body. Moreover, when forming integrally with a support body, what is necessary is just to extend an outer side board, a width | variety board, and an inner side board sequentially from the other both sides of the bottom face board of a support body, respectively. As the insertion piece, in order to make it difficult to come out from the insertion groove of the cylindrical body, for example, a cut is made in the base of the insertion piece or the insertion piece is bent. In the case of bending, it is preferable to provide a crease at the base of the insertion piece to facilitate bending, or to keep the tip in contact with the bottom plate or the polymerization plate so as to hold the inclined state.
[0010]
A “tray” is one in which two supports are connected and fixed so that the lower cylinder faces each other, and the inner plate protruding from the upper surface plate of the lower cylinder is used as the support surface of the storage body. Say. This tray has a structure in which an outer plate, a width plate, and an inner plate are sequentially extended from both sides of a mounting plate on which two supports are mounted. While covering a part of both ends of the face plate, it is provided with insertion pieces that are inserted through insertion grooves provided in the respective cylinders. In this tray, the inner plate located between the supports is provided with a crease at the same height as the upper plate of the lower cylinder, and the tip is inclined so that it is in contact with the mounting plate. The contact length with the side plate of the lower cylinder may be increased.
[0011]

In the tray 18 shown in this example, the insertion piece 14 to be inserted into the insertion groove 13 of the higher cylindrical body 2 of each support body 3 is bent by providing a crease 17 at its base. In addition, the inner plate 12 between the supports 3 is inclined by providing a crease 17 at the position of the upper surface plate 7 of the lower cylindrical body 2 and bending the tip to the mounting plate 19. I try to keep it in a state. This is because the inner plate 12 that contacts the side plate 6 of the cylinder 2 is inclined to increase the length of the contact, thereby more reliably preventing the cylinder 2 from falling to the side plate 6 side. is there.
[0019]
In this way, by integrating the two supports 3 with the tray 18, the strength as a buffer can be further increased. Moreover, since it is the structure connected with the tray 18, it becomes possible to use this tray 18 as a packaging material as it is. That is, it is possible to pack the buffer body 1 by mounting it on the storage body, or simply placing the storage body and covering the cover member with a tape.
