Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a fixed shock absorber that is used when a complex or irregular outboard motor is accommodated in a transport box and transported.
[0002]
[Prior art]
As illustrated in FIG. 7, the outboard motor is a large product having a heavy special shape with a weight of 60 to 70 kg. However, when the outboard motor is packed and transported to a remote place, it is special as described later. Careful consideration is required.
[0003]
The outboard motor includes a cowling 1 that wraps the engine, a steering handle 2, a clamp bracket 3 for fixing the outboard motor to the stern of the boat, an upper casing 4 and a lower casing 6 that protect the drive shaft, a cavitation plate 5, and a propeller. 7, the product with skeg 8 etc. as the main component, as shown in FIG. 7, the propeller attached to the lower casing can be submerged under the surface of the water to kick the water and run the boat, The legs under the cowling have a special long and narrow shape. Further, the center of gravity of the outboard motor is unevenly distributed at the lower part of the cowling, that is, at the upper part of the drive casing.
Therefore, when packing and transporting an outboard motor having such a complicated structure without dismantling it, the outboard motor will not be damaged even if the packing box is dropped during transportation or loading, or strong impacts or vibrations are applied. There was a need to install a fixed cushioning material in the packing box so that the product would not be damaged by rattling or bottoming and absorbing external shocks.
[0004]
Conventionally, when transporting a small outboard motor of about 25 to 30 horsepower, upper and lower alignment frames made of a synthetic resin molded product such as polystyrene foam are used, and the products are fitted in both frames and placed in a transport box. I was carrying it.
[0005]
However, at present, the problem of packaging waste made of synthetic resin materials such as polystyrene foam has become a global social problem regardless of the country or country. That is, when processing packaging waste made of synthetic resin, it could not be incinerated with combustibles such as paper, and it had to be separated, so there was a problem that the recovery and disposal costs were high, and when incinerated Injury gas may be generated, burned calories may increase and the incinerator may be damaged. On the other hand, when landfilling is performed, this kind of waste is not decomposed.
[0006]
Therefore, in recent years, we have developed a packaging material that combines a fixed cushioning material that uses corrugated cardboard that is easy to recycle as used paper and an exterior box that is the same paper product, clearing the problems of environmental measures, which is a drawback of the conventional type. Is desired.
[0007]
From this viewpoint, the present applicants have recently proposed a packaging box for an outboard motor comprising a combination of a cardboard frame material and an outer box in place of the foam cushioning material (see Japanese Patent Laid-Open No. 5-338669). .
This packing box is composed of a cardboard-shaped receiving frame made of corrugated cardboard folded in a corrugated cardboard shipping box and the same material, and the outboard motor supported on the receiving frame is viewed from above. Proposes a packaging box that incorporates a holding frame to hold down. More specifically, the receiving frame is formed by combining two vertical and horizontal elongate members so as to form a cross-beam shape, and by forming a hollow corresponding to the outer shape of the outboard motor in the receiving frame, Then, after folding the whole downward in a U-shape, the bent ends are formed with corresponding recesses in the outer shape of the outboard motor and recesses that engage with the vertical members, and further, A packaging technique has been proposed in which an outboard motor is accommodated between the holding frame and a conventional plastic frame material.
[0008]
However, in this prior invention, in order to transport an outboard motor having a weight of approximately 70 kg and a large shape, the load bearing strength of the receiving frame and the holding frame is weak, and when a large impact or vibration is applied, the impact or It has been found that there is a possibility that the engaging portion of both the frames may be deformed and damaged due to vibration, or the packaged product may be rattled.
Further, in this prior example, it is necessary to tightly engage the lower receiving frame and the upper holding frame, which is cumbersome and cumbersome, and an improvement in the assembly work efficiency at the time of packaging has been desired.
[0009]
[Problems to be solved by the invention]
The present invention solves the above-mentioned problems of the conventional type, and maintains the advantages of the prior invention of using all corrugated cardboard (paper material) for the packaging material as it is, and has a high load bearing strength against heavy objects and deformation. An object of the present invention is to propose a fixed shock absorber that can be easily assembled at the time of packaging and that can be packaged as it is without disassembling a large and irregular heavy object such as an outboard motor.
