Abstract: An inflatable product including tensioning beams is described. The inflatable product may include a first wall, a second wall spaced apart from the first wall, and an air chamber defined by at least the first and second walls. The inflatable product includes a plurality of tensioning beams disposed in the air chamber and coupled to the first and second walls. Each of the tensioning beams can include a first sheet made of a first flexible material and having an outer perimeter and a second sheet made of a second flexible material and having an outer perimeter, the outer perimeter of the second sheet overlapping the outer perimeter of the first sheet. Each of the tensioning beams can include a first layer, a first and a second pair of coupling layers, and a sandwiching arrangement.

Abstract: A plastic swimming pool with an enhanced structure comprises a pool wall, a connecting sheet, a base sheet and an inflatable ring, said pool wall is connected with the base sheet via the connecting sheet, the inflatable ring is mounted on a top of the pool wall, said pool wall is formed by connecting a plurality of sidewalls at both sides of them with each other into a loop, the connecting sheet is bonded to the inner side of the lower portion of the pool wall, the connecting sheet is formed by connecting a plurality of material sheets at both sides of them with each other into a loop as well, the welding seams between the sidewalls and the welding seams between the material sheets of the connecting sheet are staggered; the width of an interface for welding the sidewalls and the connecting sheet is more than 80 mm and reinforcing seals are provided in the interface where the sidewalls and the connecting sheet are bonded, and a bottom ring of the connecting sheet is connected directly with the base sheet.

Abstract: An air bed with a stable supporting structure comprises a periphery sheet, a top sheet, and a bottom sheet. A middle sheet separates the air bed into an upper air-chamber and a lower air-chamber, an outer extending strip separates the upper air-chamber into a peripheral air-chamber and an upper main air-chamber, a first set of extending strips is provided in the upper main air-chamber, a second set of extending strips, which is welded to the middle sheet and the bottom sheet, is provided in the lower air-chamber, and an oblique extending strip is provided around the periphery of the second set of extending strips and is welded with the periphery sheet and the bottom sheet to separate the lower air-chamber into a lower main air-chamber and a peripheral auxiliary air-chamber. The lower main air-chamber is a space which has a shape of an inverse cone and receives air therein.

Abstract: A built-in electrical inflating and deflating pump for inflatable product includes an air-pump, a panel, a housing and a base. The inlet of the air-pump is provided with an inlet hole communicated with external space and an inlet hole communicated with an internal space of an inflatable product respectively, the outlet of the air-pump is provided with an outlet hole communicated with external space and an outlet hole communicated with the internal space respectively as well. The first valve sheet is provided between two inlet holes, the second valve sheet is provided between two outlet holes, and each of these two valve sheets is moved between the respective corresponding inlet holes or outlet holes under the control of the valve pole and the valve sheet transmission-control device to open or close their respective corresponding inlet holes or outlet holes.

Abstract: A flexible swimming pool comprises a pool wall, a base sheet and an inflatable ring, the sidewall is a continuous sidewall, that is, there is no welding seam in a vertical direction from the top, on which the inflatable ring is connected, to the bottom, a plurality of notches are cut out in the lower edge of each continuous sidewall, the sidewall is connected directly with the base sheet, the pool wall formed of the sidewalls connected into a loop is connected with the inflatable ring at its top to support the pool wall in a vertical direction, and a sidewall bottom ring folding inwards which is formed by overlapping and bonding the material sheets of both sides of each notch is connected directly with the base sheet. The advantage of the present invention is that it has reduced the welding seams at the lower edge of the sidewall to make the strength of the pool increased and the probability of water-leaking decreased greatly.
