Inflatable cushion structure

The present invention relates to an inflatable cushion structure, and more particularly to providing an inflatable cushion which in particular provides a thermal insulation layer.

Press, the general inflatable cushions are used outdoors, such as hiking, wild outings, etc., and can be deflated and inflated for users to carry and use conveniently, please refer to the ninth to eleventh figures, The inflatable cushion 90 is mainly coated on the upper and lower layers 91, 92 with a film layer 93, 94 which can be adhered to each other and is gas-tight, and is sealed and sealed at the periphery, and the upper and lower layers 91, 92 are A plurality of straps 95 are bonded to each other by a splicing machine. The plurality of straps 95 are disposed in parallel, and are respectively adhered to the upper and lower layers 91 and 92 by the upper and lower ends thereof to form a plurality of parallel and communicating air passages 96 ( Since the length of the strap 95 is smaller than the length of the inflatable cushion 90, after the inflatable cushion 90 is bonded to the strap 95, the two ends of the inflatable cushion 90 are open, so that the air passages 96 can be circulated, and One side of the inflatable cushion 90 is provided with a gas valve 97. If, by the air inlet of the air valve 97, the air is circulated by the air passage 96 to fill the entire inflatable cushion 90, so that the inflatable cushion 90 has elasticity. For the user to provide lying while hiking or in the wild, however, the inflatable cushion 9 There is no heat-insulating material in the 0, which causes the inflatable cushion 90 to have no warming effect. Therefore, the operator fills the airway 96 with warmth materials, such as fluff, cotton wool and other lightweight articles, so that the warmth effect can be achieved. But the lightweight items such as fluff and cotton wool are filled in the air passage 96, because The circulation of the air makes the lightweight items such as fluff and cotton wadding unable to be fixed at the same position, so that the warmth in the inflatable cushion 90 is not uniformly filled, thereby causing poor warming effect and affecting the speed of inflation.

Therefore, the creators of this case have been based on their years of experience in the design and manufacture of inflatable cushions and automatic inflatable cushions. It is known that the existing inflatable cushions can provide a comfortable lying and lying surface, but the overall warmth protection effect is still not The ideal is to strive for excellence, to provide better design to meet and meet the needs of consumers, and to actively research, design and change, and ultimately the creation of this creation.

The main purpose of the creation is to bond the surface layer of the inflatable cushion with a heat-insulating layer between the pull belt and the surface layer of the inflatable cushion, so that the heat-insulating layer is restricted by the surface layer and the belt between the inflatable cushion. The inflatable cushion is placed between the surface layer and the drawstring on the inflatable cushion to achieve a warming effect.

Another purpose of the present invention is to have a draw tape adhered to the inner surface of the inflatable cushion, and a heat insulation layer is bonded between the surface of the pull tape and the air cushion or the upper layer of the drawstring and the lower layer. The perforations are arranged, and the bonding section between the drawing tape and the upper surface of the inflatable cushion and the lower surface layer can be located at the through-hole position of the thermal insulation layer without being interfered by the thermal insulation layer, so as to achieve a positively bonded inflatable cushion.

A further object of the present invention is to reduce the obstruction of air entering the inflatable cushion by means of a plurality of through-grooves on the drawstring to achieve an inflatable cushion that accelerates the inflation effect.

In order to achieve the above purpose, the present invention mainly covers a layer of adhesive film which can be adhered to each other and is gas-tight in the upper and lower layers, and is sealed by the periphery, and is on one side of the inflatable cushion. A gas valve is disposed, and a plurality of side-by-side drawstrings and an insulation layer are accommodated in the upper and lower layers, wherein: the upper and lower ends of the drawstring are respectively a first adhesive section and a second adhesive section, The first bonding segment and the second bonding segment can provide a plurality of bonding points with the film layers in the upper and lower layers, and the bonding portion is a point-to-point mutual relationship between the first bonding segment and the upper surface layer and the second bonding segment and the lower surface layer Bonding, and a plurality of through-grooves are disposed between the first bonding section and the second bonding section on the strap; the insulating layer is a heat insulating cotton, an aluminum foil or a material capable of absorbing heat, and the insulating layer is placed thereon Between the surface layer and the draw tape, the heat insulating layer is provided with a plurality of perforations arranged in a position, and the through holes are located at a position where the first bonding portion and the upper surface layer are bonded to each other, and the inner diameter of the through hole is larger than the bonding portion The maximum outer diameter.
