[Prior art]

 Shock absorbers worn on the body as various protectors, shock absorbers used to protect articles during the transportation of articles, etc., and used to reduce the impact when contacted by being provided on ships or vehicles. The cushioning tool, the assisting means for swimming, the assisting means for swimming lessons, and the floats used for various life-saving means are effective against the bulkiness of the cushioning tool and the floats. Since it is necessary to provide the cushioning function and the floating function to the cushioning device, the floating device, etc., it is often used by enclosing air in a tube or a mat-like bag that provides airtightness. It was

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 used when carrying, carrying or storing. Air is extracted from the float and 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 a shock absorber or such a float, it is necessary to fill the shock absorber or the float with air 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. It took a lot of time, labor and, in some cases, assembly of a suitable structure or equipment of equipment in order to effectively use it as a shock absorber or float.

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

In addition, such a float or cushion is made of a material such as rubber that is highly stretchable like rubber and is suitable for the construction of an airtight bag. Because of this, the manufacturing cost is high, and there is the inconvenience that air leakage easily occurs due to fatigue of the bag body due to aging of the material, etc. There is a disadvantage in that the bag forming the tool or the float has a hole and does not function as the shock absorber or the 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 carrying, storing, or equipping it, but on the other hand, it has the feature of always providing a predetermined cushioning function to the wearer. In this type of plastic foam material as well, a floating device made of an independent foamed plastic material or an open-celled foamed plastic material containing closed cells has a certain volume when carrying, storing or equipping. On the other hand, although it has tension, it has a characteristic that it always gives a predetermined floating force to the floats, etc. that are constructed by them, and the floating force is not impaired over time. There is no inconvenience such as the decrease of the cushioning function of the cushioning tool or the floating function of the floater due to the air leakage as in the above.

From this point of view, shock-absorbing means such as various protectors worn on the body, shock-absorbing means used for protecting various kinds of articles during transportation, contact with ships or vehicles, etc. Alternatively, an attempt was made to develop a shock absorber made of a plastic foam material as a shock absorbing means for mitigating the shock caused by a collision. In addition to the swimming aid, horizontal training aid, etc., a rescue tool that is permanently installed on ships, and even floaters such as life jackets are floats that use the above plastic foam material. It is meaningful to make use of, and especially it is necessary to be permanently installed in a state in which it can be used as a float, for example, swimming aids, swimming training aids, ship permanent rescue means, life jackets on board. As a float, the float made of the above-mentioned plastic foam material was attempted to be developed.

[0010]

[Problems to be solved by the device]

 However, when this type of plastic foam material is configured as a shock absorber or float, etc., the band, cord, etc. required to attach the shock absorber, float, etc. to the body, etc. It is difficult to attach to the plastic foam material, for example, by using a band, a string, etc., to bind the plastic foam material in the shape of a shock absorber or a float, or to use a plastic foam formed in the shape of a shock absorber or a float. By piercing the stick foam, the cord, etc., through the stick foam with an appropriate puncturing tool, the plastic foam material that constitutes the shock absorber or float is replaced by the shock absorber or float. Attempts were made to equip a belt, a string, etc. as a wearing means.

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, cord or the like is tied, and the shock absorber or float or the like is formed using the tied band or cord. When attaching to the body, it is easy to be uncertain that the plastic foam material will be tied up with this band or string, and the band or string that the plastic foam material is connecting while using it as a shock absorber or float. There was a risk of getting out of it, and it was difficult to use it as a shock absorber or float. Also, in the case of the shock absorbers or floats constructed by such a method, since the shock absorbers or floats are attached to the body using a band or string tied to the plastic foam material, The plastic foam material as a shock absorber or float cannot be attached in close contact with the body, etc., and the fit feeling when the shock absorber or float was worn was difficult.

Next, an attempt was made to make a hole through the plastic foam material by using a piercing tool or the like, and to insert a band, a string 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 trace of the puncture hole will be blocked as the puncture tool is pulled out, and the band and cord will not be attached. It is difficult to provide a hole that allows easy and reliable insertion, 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 will be uneven. There were some inconveniences, such as the hole diameter depending on the location.

From this point of view, it has been attempted to construct a shock absorber or a float by inserting a string, a band and the like into a plastic foam material together with an appropriate puncture instrument. However, it is difficult to specify the insertion / removal position of this piercing tool for a string or band that is attached to the plastic foam material by such a method. In addition, it is difficult to insert a string or band so that it extends over the length of the thin plastic foam material, and there are certain restrictions on the shape and size of the plastic foam material to which the string or band is attached. was there. In addition, in such a method, it is difficult to insert the band, the cord, etc. along the same insertion portion when the string, the band, etc., which have been inserted, come off, and the separate insertion tool It is necessary to insert the string, band, etc. to be reinserted through the plastic foam material by using, and as a result, a plurality of puncture scratches may occur in the plastic foam material. There was the inconvenience that the strength was lost enough to use it as a float.

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

The mounting plastic foam material according to the present invention can be used as a cushioning material or an immediate floating tool in view of the inconvenience of conventional mounting plastic foam materials such as cushioning materials or floaters on the above. Various types of plastic foam materials for mounting that do not impair the function as cushioning materials or floats for a long period of time. The purpose is to provide inexpensive plastic foam materials.
