Air mattress and inflatable product
The present invention relates to an air mattress and inflatable product. The air mattress includes top and bottom sheets made of a flexible airtight material, and an airtight inflatable compartment formed at least partially by the top and bottom sheets. The air mattress further includes a plurality of elongated flexible strips positioned within the airtight inflatable compartment, each of the strips including a plurality of first bonding portions, intermediate connecting portions and second bonding portions arranged in order along the length direction of the strips, wherein the first bonding portions are bonded to an inner surface of the top sheet to form first bonding surfaces, the second bonding portions are bonded to an inner surface of the bottom sheet to form second bonding surfaces, and the intermediate connecting portions are positioned between the first bonding portions and the second bonding portions. The present air mattress is not only lightweight and flat but also has a simple structure so as to be suited to automated production, thereby reducing productions costs.
1. An air mattress, comprising top and bottom sheets made of a flexible airtight material, and an airtight inflatable compartment formed at least partially by the top and bottom sheets;
wherein:
the air mattress further comprises a plurality of elongated flexible strips positioned within the airtight inflatable compartment, each of the strips includes a plurality of first bonding portions, intermediate connecting portions and second bonding portions arranged in order along the length direction of the strips, wherein the first bonding portions are bonded to an inner surface of the top sheet to form first bonding surfaces, the second bonding portions are bonded to an inner surface of the bottom sheet to form second bonding surfaces, and the intermediate connecting portions are positioned between the first bonding portions and the second bonding portions, wherein the intermediate connecting portions are perpendicular to the first bonding portions and the second bonding portions.
2. The air mattress of claim 1 , wherein the length of the first bonding portions is equal to the length of the second bonding portions.
3. The air mattress of claim 1 , wherein the air mattress further comprises at least one second elongated flexible strip which is aligned with at least one of the elongated flexible strips;
wherein the second elongated flexible strip includes a plurality of first bonding portions, intermediate connecting portions and second bonding portions arranged in order along the length direction of the strip, wherein the first bonding portions are bonded to the inner surface of the top sheet to form first bonding surfaces, the second bonding portions are bonded to the inner surface of the bottom sheet to form second bonding surfaces, and the intermediate connecting portions are positioned between the first bonding portions and the second bonding portions;
wherein at least one of the first bonding portions of the second elongated flexible strip is positioned between the adjacent first bonding portions of the at least one of the elongated flexible strips, and at least one of the second bonding portions of the second elongated flexible strip is positioned between the adjacent second bonding portions of the at least one of the elongated flexible strips.
4. The air mattress of claim 1 , wherein the air mattress further comprises a side sheet, which is hermetically bonded to the top and bottom sheets to form the airtight inflated compartment.
5. The air mattress of claim 4 , wherein the air mattress further comprises at least one elongated flexible strip arranged within the airtight inflated compartment between opposite wall portions of the side sheet,
wherein the at least one elongated flexible strip includes a plurality of first bonding portions, intermediate connecting portions and second bonding portions arranged in order along the length direction of the strip, wherein the first bonding portions are bonded to an inner surface of one wall portion of the side sheet to form first bonding surfaces, the second bonding portions are bonded to an inner surface of the other wall portion of the side sheet to form second bonding surfaces, and the intermediate connecting portions are positioned between the first bonding portions and the second bonding portions.
6. The air mattress of claim 1 , wherein the elongated flexible strips are made of fabrics which are coated on both sides thereof with Polyurethane (PU) material, fabrics laminated on both sides thereof with a Thermoplastic Polyurethane (TPU) film, or a Thermoplastic Polyurethane (TPU) film.
7. The air mattress of claim 1 , wherein the first bonding portions and the second bonding portions are bonded to the inner surfaces of the top and bottom sheets respectively by a high frequency welding process or a thermal welding process.
8. An inflatable product, comprising two opposite walls made of a flexible airtight material, and an airtight inflatable compartment formed at least partially by the walls;
wherein,
the inflatable product further comprises at least one elongated flexible strip positioned within the airtight inflatable compartment, the strip includes a plurality of first bonding portions, intermediate connecting portions and second bonding portions arranged in order along the length direction of the strip, wherein the first bonding portions are bonded to an inner surface of one wall to form first bonding surfaces, the second bonding portions are bonded to an inner surface of the other wall to form second bonding surfaces, and the intermediate connecting portions are positioned between the first bonding portions and the second bonding portions, wherein the intermediate connecting portions are perpendicular to the first bonding portions and the second bonding portions.
