Abstract: This invention relates to a tube connector for connecting a plurality of tubes, said tube connector comprising: a first cover including a first groove and a third groove; a second cover including a second groove and a fourth groove, said first and second grooves forming a first tube accommodation space, and said third and fourth grooves forming a second tube accommodation space; a fastener for fastening the first cover and the second cover; and a springy member secured between the first and the second covers for detaching the same when the fastener is loosened.

Abstract: A polygonal tube rack connector includes a lid and a carrier incorporated to each other by means of multiple fasteners; multiple non-linear grooves are disposed on the connector to accommodate mounting of multiple linear tubes; a limiting hole being disposed to each groove to facilitate fast and direct insertion of a stud from a tube to secure the tube in the groove without slipping off; and the tube can be easily removed by loosening up those fasteners for replacement.

Abstract: A tube rack connector includes a lid and a carrier incorporated to each other, multiple slots and secondary slots being disposed on one side each of the lid and the carrier to receive an elastic member; and multiple fasteners each inserting through a locating hole and a connecting hole respectively from the lid and the carrier to allow a stud from a tube to fast and directly insert into the limiting hole to secure the tube in the groove without slip and deflection and convenient replacement of a tube by loosening up without removing the fasteners since both of the lid and carrier are held open due to elasticity exerted from the elastic member.

Abstract: A connector for a pipe frame includes a first cover and a second cover. The first and second covers have first and second longitudinal grooves and first and second transverse grooves. Further, on both sides of the first and second longitudinal grooves, one end of the first and second transverse grooves, between the first longitudinal and transverse grooves and between the second longitudinal and transverse grooves, are respectively provided with fixing holes and connecting holes. Further, fixing elements are provided in the fixing holes and the connecting holes corresponding to the first cover and the second cover, respectively. With the above structure, the desired pipe bodies can be disposed in the first and second longitudinal grooves and the first and second transverse grooves. Further, with the fixing elements being locked in the fixing holes and the connecting holes, it is easy to achieve the assembling and disassembling operations.

Abstract: A high strength inflatable mattress comprises: an upper surface, a lower surface, at least one side surface, a plurality of tightening sheets and at least one gas valve. The upper surface, the lower surface and the side surface have two PVC compound layers and a fiber layer, wherein the fiber layer is disposed between the two PVC compound layers. The side surface comprises PVC compounds, and the side surface is connected to the upper surface and the lower surface by a thermal melting method (such as thermal pressing, ultrasonic welding, or utilizing hot air, RF welding, hot wedge) to form a gas containment space surrounded by the upper surface, the lower surface and the side surface. Each tightening sheet is connected to the upper surface and the lower surface by the thermal melting method too.

Abstract: An inflatable air cushion has at least two sets of tension members therein. Each set of tension members includes multiple and parallel tension members. The tensile directions generated by the two sets of tension members are perpendicular. One of the tension members can be a strap member, and the other tension member can be a sheet member.

Abstract: An inflatable furniture assembly of has a plurality of inflatable cushions, inflation valves, covers, and connecting elements. The inflatable furniture assembly is formed from the plurality of inflatable cushions; each inflatable cushion has an inflation valve and can be covered by a cover to form a unit with an improved appearance. The cover comprises at least one opening corresponding to the inflation valve so that each unit can be inflated. Each unit has at least one connecting element that comprises self-adhesive tape or connecting rod so the units can be combined with the self-adhesive tape to form the inflatable furniture assembly.
