2. Description of the Related Art Shock absorbers worn on the body as various protectors, shock absorbers used to protect articles during transportation of articles, etc., are provided on ships or vehicles to reduce the impact at the time of contact. The cushioning tool used for this purpose, the assisting means for swimming or the assisting method for swimming lessons, and the floats used for various life-saving means are effective against the bulkiness of the shock absorbers and floaters. Since it is necessary to provide a proper cushioning function and a floating function to the cushioning tool, the floating tool, etc., there is a tube or a mat-like bag which is airtightly sealed with air. .

The advantage of such a shock absorber or float is that when the shock absorber or float is not used as a shock absorber or float, the shock absorber or float may be stored, stored or stored. The air is removed from the float or the like to be contracted or folded to make it compact, and in this compact state, the shock absorber or float can be carried or stored.

On the other hand, however, in the case of using a shock absorber or such a float, it is necessary to fill the air into the shock absorber or float every time it is used, and it takes a lot of time to fill the air. It may be labor-intensive, and a structure for air filling may be provided in the shock absorber or float, and equipment for air filling may be required separately, which is convenient for carrying, storing or equipping, but cushioning. It takes a lot of time, labor, and in some cases, assembling of appropriate structure or equipment of equipment in order to effectively use it as a tool or float.

In addition, such a floating device is filled with air between the floating device and the storage condition between the stored or stored condition and the used condition, so that in an emergency, for example, when a ship is capsized. It is not suitable for cases such as when it is necessary to immediately act as a float.

Further, such a float or cushion is made of a material such as rubber which is highly elastic and is suitable for the construction of an airtight bag. As a result, the production cost becomes high,
Moreover, it has the disadvantage that air leakage easily occurs due to the fatigue of the bag body due to aging of the material, etc., and when it collides with a sharp part, etc., a hole is formed in the bag body forming the shock absorber or floater. However, it has a disadvantage that it does not function as a shock absorber or a float.

From this point of view, development of a cushioning material using various plastic foam materials, and in particular a floating tool using a closed-cell foamed plastic material or an open-cell foamed plastic material containing closed cells, etc. Has been developed.

The cushioning material using this type of plastic foam material has the disadvantage that the cushioning material is bulky when it is carried, stored, or equipped, but on the other hand, it has the feature of always providing a predetermined cushioning function to the wearer. Even with this type of plastic foam material, closed cell foamed plastic material or floats made of open celled foamed plastic material containing this closed cell, etc., will have a certain bulk when carried, stored or equipped. On the other hand, it has a characteristic that it always gives a predetermined floating force to the floats and the like that they constitute, and the floating force is not impaired over time. There is no inconvenience such as a decrease in the cushioning function of the cushioning tool or the floating function of the floater due to the air leakage.

From this point of view, shock-absorbing means such as various protectors worn on the body, shock-absorbing means used for protecting various articles during transportation of various articles, contact or collision with ships or vehicles, etc. An attempt was made to develop a shock absorber made of a plastic foam material as a shock absorbing means for reducing the accompanying shock. In addition, as a means for swimming, a means for horizontal training, etc., a rescue tool that is permanently installed on ships, etc., and a float using the plastic foam material as a float for life jackets, etc. In particular, it is necessary to be permanently installed in a state where it can be used as a float, for example, a swimming aid, a swimming training aid, a permanent rescue device, a floating life jacket, etc. As a tool, an attempt was made to develop a float made of plastic foam material.

[0010]

However, this type of plastic foam material is necessary for mounting the shock absorber, float or the like on the body when the plastic foam material is configured as the shock absorber or float. It is difficult to attach a band, string, etc. to the plastic foam material concerned.
A plastic foam material having a shape such as a shock absorber or a float is bound with a string or the like, and a plastic foam material configured in a shape such as the shock absorber or a float is provided with an appropriate band, cord or the like. An attempt was made to equip a plastic foam material forming a shock absorber or a float with a band, a string or the like as a mounting means for the shock absorber or the float by piercing with a piercing tool. Was given.

[0011] However, for example, a plastic foam material that has been adjusted to a shape such as a shock absorber or a float using the above-mentioned band or cord is tied, and the shock absorber or float is tied using the tied band or cord. When wearing on the body, etc., the binding of the plastic foam material with this band and the string is apt to be uncertain, and the plastic foam material during use as a shock absorber or a float,
There is a risk that it may come out of the band or the string that is tied, and it is difficult to use it as a shock absorber or float. Also, in a shock absorber or float which is formed by such a method, since the shock absorber or float is attached to the body using a band or a string tied to a plastic foam material, Since the plastic foam material as the shock absorber or the float cannot be attached in close contact with the body or the like, there is a difficulty in fitting when the shock absorber or the float is attached.

Next, it was attempted to make a hole through the plastic foam material by using a piercing tool or the like, and to insert a band, a cord or the like into the hole. However, even if the puncture tool is inserted through the plastic foam material that constitutes the shock absorber or float, the puncture hole trace will be blocked as the puncture tool is pulled out, and the band and cord can be easily attached. In addition, it is difficult to provide a hole that can be reliably inserted through, and even if a hole that allows easy and reliable insertion of a band and a cord is provided, the shape of the formed hole is uneven and There were inconveniences, such as the diameter being different depending on the location.

From this point of view, together with an appropriate piercing tool, a string,
Attempts have been made to construct a shock absorber or float by inserting a strip or the like into a plastic foam material. However, it is difficult to specify the insertion / removal position of this piercing tool for the string, band, etc. attached to the plastic foam material by such a method.
In addition to the inconvenience of attaching a band or the like, it is difficult to insert a string, a band, etc. through the length of the thin plastic foam material, and the shape and size of the plastic foam material to which the string or band is attached There were certain restrictions on the size. In addition, in such a method, it is difficult to insert the band, the band, etc., along the same insertion part when the string, the band, etc. that have been inserted are removed, and a separate piercing tool It is necessary to insert the string, band, etc. to be reinserted through the plastic foam material using
This causes a plurality of puncture scratches on the plastic foam material, resulting in the disadvantage that the plastic foam material loses sufficient strength to be used as a shock absorber, a float, or the like.

From this point of view, it is also possible to foam the plastic foam material in the mold so as to form a shock absorber or a float so that the plastic foam material is provided with a hole for inserting a string or a band in advance. It is conceivable that the cost of molds such as molds is high in such mold molding, and the molding cost is also high, and the shape and dimensions of the shock absorbers or floats to be molded are standardized. It is difficult to provide shock absorbers or floats that meet various needs, and because they are foamed at the molding stage, there are many variations in the product finish, and low quality cushions or floats for high product costs. There was an inconvenience.

The mounting plastic foam material according to the present invention has been considered in view of the inconvenience of the conventional mounting plastic foam material such as the cushioning material or the float on the above.
It can be used as a cushioning material or instant float, etc., and it is easy to make various kinds of plastic foam materials for mounting that does not impair the function as a cushioning material or float, etc. for a long time, and can be made according to the standard The purpose of the present invention is to provide a plastic foam material for mounting structure, and to provide the mounting plastic foam material at low cost.
