Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in air bladders and other air expansion bodies.

Layer two non-breathable sheets and heat seal the same side edge.
Air expandable bodies in which air chambers are formed by bonding or the like are known. If a plastic such as vinyl chloride is used for the sheet, high frequency bonding can be performed.

In this type of air expandable body, the circumferential edges that are polymerized and bonded to each other are formed by the expansion of the air expandable body.

It makes waves and becomes shorter in length. Therefore, the size and shape of the circumferential line become unstable, making it difficult to join the air expandable body to another object via the circumferential edge.

Therefore, the present invention provides an air expandable body in which a reinforcing joint is formed in a part of the peripheral edge so that the dimensions and external shape are stable, and the air expandable body can be joined to other objects through the reinforcing joint. The purpose is to provide.

Terms used in the detailed description of this invention are defined as follows.

(1) A non-breathable thermoplastic plastic sheet is a flexible sheet that is made entirely or partially of plastic, fuses and deforms when heated or compressed, and seals to prevent air or gas from entering. This is to prevent leakage.

The air chamber is equipped with an air blowing valve to form an air expansion body.

(6) The inner part and the outer part are parts of the air expandable body,
The inner part is opened like a window, and the surrounding area is tightly sealed.
The outer parts are in close contact with each other at the outer edges of the air inflatable body, and the inner and outer parts also include the surrounding parts.

(4) Reinforced and stable joints are those applied to the inner and outer parts by heating and compression, reinforcing and stabilizing the inner and outer parts that deform due to expansion and contraction. This joint is flat, does not deform like a wave, and has a constant length.

(5) Stable joints are heat sealed for stability.

(6) The basic body of the air expandable body is not provided with joints for reinforcement.

(7) Complex refers to a composite of multiple components.

(8) Direct heat sealing is heat sealing that is performed by directly pressing a heating member against the area to be sealed.
Indirect heat sealing is a sealing method performed by electronic action due to the dielectric constant properties of heated plastics, such as high frequency welding.

(9) Pressure means pressurizing the sheet with upper and lower dies,
Refers to the pressure applied to stabilize the bond.

(10) The bonding means is a means for bonding by mechanical, physical, chemical, or electrical means.

(11) Various materials include textiles, wood, metal, paper,
Glass and plastics (soft and hard) are used.

(12) Shortening and stretching refer to changes in dimensions at the joined peripheral edges that occur when the air expandable body expands and contracts.

In the air expandable body of the present invention, a reinforcing joint is formed on the peripheral edge surrounding the air chamber, and the peripheral edge is formed by the joint.
Its main characteristics are that it is stable in size and external shape, does not deform due to expansion and contraction of the air chamber, and can be joined, connected, and combined with other objects accurately and easily.

The air expandable body of this invention can be joined, connected, or combined with other materials including plastics by direct heat sealing, indirect heat sealing, threads, strings, adhesives, snaps, buttons, eyelets, rivets, pins, etc. This can be done by means such as clips, and other materials include fabrics, fabrics, metals, glass, non-thermoplastics, etc.

What is shown in FIG. J is a thermoplastic sheet with a plurality of air chambers 22. ．． 2.2. Each air chamber 22 is provided with an air blowing valve 23.

The various basic structures of the air expandable body described above can accommodate required changes in coloring, thickness, robustness, etc.

The air expandable body shown in FIG. , are partially joined by a plurality of joints jff to form a communicating air chamber, and expansion and contraction of the air chamber is performed via an air blowing valve λ.

Figure 1 shows an air-expandable body that has been inflated with air.

The outer peripheral edge 27 located at a position perpendicular to the joint portion 2g is wavy.

As shown in FIG. 7, the outer edge 30 of the air-expanding body is heated and pressed by a heat-sealing die 2, and is reinforced over its entire length, so that it is not affected by expansion or contraction, that is, it has a corrugated shape. It becomes a stable part that is reinforced to prevent it from becoming wrinkled or wrinkled. The heat seal on the outer edge 30 may be provided in a plurality of strips, and the outer edge of the air expandable body is reinforced by the heat seal in one or more strips.

FIG. g shows an air expandable body with a reinforced outer edge 30, in which the outer edge 3/ of the reinforced joint 32 is wavy and deformed. Therefore, the outer edge 3/, which deforms in this way, can be cut off at the same time when heat-sealing the joint 3-2 (using a bladed die), and the joint 32 can be positioned on the edge. The length of the portion 32 is constant, and the length does not change during expansion and contraction, and the reference numeral 2t indicates the joining side edge of the air expandable body.

Ru. In Fig. 7, the air expandable body is reinforced by heat sealing while it is expanded, but this is for convenience of explanation, and normally the air expandable body is contracted after being clamped to a heat sealing die. Since the reinforcing heat-sealing is carried out after being flattened, no stress is applied to the parts that need to be reinforced and stabilized.

The air expandable body of the present invention can be joined, connected, or combined with other objects via the reinforced portion as described above. This joining, connection, and combination are performed in various ways.
