DETAILED DESCRIPTION OF THE INVENTION

Refer to FIG. 1a. FIG. 1a exemplifies an embodiment of an inflatable mattress 10 according to the invention.

In FIG. 1a, the inflatable mattress 10 has an upper layer structure 101, an inflatable middle layer 105 and a bottom layer structure 102. The upper layer structure 101 has a top surface portion, that is the inner rectangular region of the upper layer structure 101 in the FIG. 1a. The top surface portion covers more than 70% of the area of the upper layer structure facing up, and the top surface portion can connect to the bottom layer structure 102 by a plurality of Y-type drawstrings

The upper layer structure 101 can include a basic fabric layer and a covering layer. The basic fabric layer is woven by a plurality of fabric fibers. the number of weft and warp fibers per square inch are higher than 100.

The basic fabric layer orients toward the direction of the coverage layer, pressing and embedding into the covering layer and constituting a fabric surface laminating material.

The so-called pressing and embedding the basic fabric layer into the covering layer is, by pressing the basic fabric layer and the covering layer, the uneven surface of the basic fabric layer having fibers directly or indirectly pressing the covering layer via glues, so that the surface of the covering layer generating a certain degree of concavity, and thus composing a more stable pressing result.

The inflatable middle layer 105 can be fixedly connected to the upper layer structure 101 on a first surface of the inflatable middle layer by the drawstrings 106, and fixedly connected to the bottom layer structure 102 on a second surface of the inflatable middle layer.

The inflatable middle layer 105 can have one or more than one inflation holes which conducting the inflation to the inflatable middle layer 102 by an exterior inflation pump. Another approach is to integrate the inflation pump and the inflatable middle layer 105, providing an inflation power by plug-in or other ways. The inflatable middle layer 105 comprises at least one air chamber configured to provide a predetermined shape after expansion during the inflation. In practical manufacturing, more than two air chambers can be designed, these air chambers maintain certain independence even by the corresponding mechanism (such as a unidirectional valve), so that another air chamber still can maintain a certain supporting force when an air chamber is under leakage. In addition, if the mattress is designed to be used by two people, the air chamber corresponding to the mattress can be designed to have a buffer space between the two sets. By this way, even a first user lying on one side turns over, a second user sleeping on the other side will not be directly affected by excessive vibrations. The buffer layer can be constituted by vibration isolated materials in itself such as an air chamber with lower pressure or sponges, etc. Or, the gases between the two sets of air chambers do not connected with each other, so as to generate an effect similar to the independent cylinder of the conventional mattresses.

In addition, the periphery of the inflatable middle layer 105 has a surrounding side drawstring 103. The side surrounding sheet outstretches a surrounding three-layer structure by at least one side drawstring. The side drawstring can be plastic materials, fabric fiber materials or other connection materials which can provide a certain tension and supporting forces. by ways of high frequency welding or paste . . . etc., the side surrounding sheet 103 is connected to other portions of the inflatable mattress 10, so as to maintain the inflatable mattress 10 to keep a predetermined shape during inflation.

The side drawstring can be plastic materials, fabric fiber materials or other connection materials which can provide a certain tension and supporting forces. by ways of high frequency welding or paste, etc., the side surrounding sheet 113 is connected to other portions of the inflatable mattress 11, so as to maintain the inflatable mattress 11 to keep a predetermined shape during inflation.

In other words, the inflatable middle layers 105, 115 can be constituted by various kinds of different structures. Besides, since the top surface portion of the upper layer structures 105, 115 are main parts in touch with users, therefore, the top surface portion can include structures constituted by the fabric surface laminating materials, so that the fabric surface laminating materials oriented toward users are constituted by fabric surfaces. Of course, based on considerations of factors on designs and convenience of manufacturing . . . etc., this kind of fabric surface laminating materials can also extend to the whole upper layer structures 101, 111, or even extend to the side surrounding sheets 103, 113. If one hopes the mattresses can be designed to be used on two side, the bottom layer structures 102, 112 can be directly designed to be the same as the design of the upper layer structures 101, 111.

Likewise, one conduct the lamination between the basic fabric layer 211 and covering layer 213 by the glues. From FIG. 2b one can clearly see the basic fabric layer 211 pressing and embedding into the surface of the covering layer 213, so that the two (211, 213) join more closely together.

In one embodiment, the covering layer can have a polarity, and by this characteristic, the covering layer can be fixed to the inflatable middle layer by way of high frequency welding. For example, the covering layer can use PVC materials. Comparing to similar materials (with respect PVC materials), PVCs are easily being processed, capable of recycling for continuous use, high strength, superior geometrical stability.

In one embodiment, the fabric fiber of the basic fabric layer has number of fibers of more than 50 and less than 300 per square inch in weft direction and warp direction. For example, the basic fabric layer can be constituted by polyester fibers of 75D×75D or 110D×80D. Wherein the “D” means the standard unit of the wire diameter of 1 gram per 9 kilometers used in the industry.

In one embodiment, the glues can withstand drawing forces larger than 20 newtons per 3 centimeters. In one embodiment, the material of the glues is PU glue with viscosity between 350000 CPS to 100000 CPS. For example, the PU glues can be adopted for the glues with viscosity between 350000 CPS to 100000 CPS, or between 40000 CPS to 60000 CPS. The PU is the polyurethane material, and the CPS is a measurement unit for viscosity in the industry.

Set different amount of glues according to different standards of laminating firmness. The higher the standard of the laminating firmness, the more the amount of glues, and the higher the costs. Preferred approaches are such as between 20 N/3cm to 100 N/3cm, or between 10 N/3cm to 50 N/3cm, and the amount of glues is 10 g/Y2 to 100 g/Y2. The “N” represents the newton, and the g/Y2 represents the amount of glues per square yard.

There can be different settings according to different specifications, materials, and glue formulas of the basic fabric layer. Also, the basic fabric layer can be doped with flame retardant material. For example, by doping flame retardant material or a fireproof treatment, the ignition point of the basic fabric layer is larger than 300 degrees Celsius.

In FIG. 3a, the covering layer can have embossed patterns. The embossed patterns of the covering layer can be pressed out by one side of an embossing roller or by conducting rolling pressing on all two sides, thus generating the corresponding embossed patterns. In FIG. 3a, one can press out horizontal and vertical parallel embossed stripes 311 on the covering layer 31 manufactured by materials of PVC, etc. by the roller. Comparing to other portions 312, the embossed strips 311 can have a certain degree of protrusions. By designs of the embossed stripes 311, one can not only create higher stability and structural drawing forces, better effects can also be generated with respect to the cement of the basic fabric layer.

In FIG. 3b, the covering layer 32 has protrusive embossed patterns 321. Different from the design of the embossed stripes with staggered arrangements in horizontal and vertical directions in FIG. 3a, the embossed stripes in FIG. 3b constitute hexagonal shapes similar to honeycomb shapes, bringing better structural stability. In the point of view of manufacturing, it means one can manufacture a thin layer having the same strength using thinner materials. This approach can further reduce the manufacturing costs.

In FIG. 3c, the covering layer 33 also has protrusive embossed blocks 331 distributed between the embossed stripes arranged in horizontal and vertical directions (i.e. the black geometrical block patterns as marked).
