Abstract: Provided is a novel inflatable bed, which relates to the field of articles for daily use. The novel inflatable bed comprises a bed body and a closed annular pull strap. The bed body is provided with a main air chamber. The closed annular pull strap has two annular edges, the closed annular pull strap is provided in the main air chamber, the two annular edges are respectively welded to two adjacent bed walls of the bed body, so that the main air chamber is separated to form a central air chamber and an edge air chamber. A weld seam formed by welding at least one of the two annular edges with the bed body has at least one broken portion, so as to form a channel making the central air chamber and the edge air chamber in communication at the broken portion.

Abstract: A pool apparatus configured to carry liquids has a side wall and a bottom surface. The side wall has a plurality of structure drawstrings, an outer side wall, and an inner side wall. Two sides of the structure drawstrings draw respectively the outer side wall and the inner side wall, so as to maintain a predetermined shape of the pool apparatus. The structure drawstrings include a main drawstring portions and at least two branch drawstring portions. The main drawstring portions have a first main string side configured to connect a first branch drawstring side of the at least two branch drawstrings. A second branch string side of the at least two branch drawstrings connects respectively to different positions of the outer side wall and the inner side wall.

Abstract: A disposable or limited use sleeping bag kit including a sleeping bag made of a multi-layered material, an inflatable pillow and storage pouch from which air may be evacuated. The layered material of the sleeping bag may be made of an inner layer for contacting a user, an outer layer providing water and abrasion resistance, and a middle insulating layer between the inner and outer layers.

Abstract: An apparatus has a first section having a hollow interior that is filled with air, and a second section attached to the top of the first section and having a hollow interior that retains a liquid.

Abstract: A waterbed having inside air cushion and method of manufacturing same is disclosed. The method comprises forming a watertight bladder having valve means thereon, forming an inflatable air cushion inside the watertight bladder, forming at least one air valve extended from the air cushion through the watertight bladder and secured thereat, inflating the air cushion, filling water into the watertight bladder, and drawing air out of the watertight bladder until the amount of air in a predetermined space of the watertight bladder is substantially reduced to less than 20% by volume, and a water screen is thus formed around the air cushion due to siphonage. The invention can provide an increased degree of softness to the skin of a user, suitably taking away heat from the body of the user, and making muscles supple when the user rolls thereon due to the compressibility of the air cushion.

Abstract: A waterbed system is provided. The waterbed system comprises a water fillable bed mattress, a plurality of transverse partitions, an air bag unit, and a bed protecting cover. The plurality of transverse partitions serve to dissipate the water disturbances caused by the weight and movement of a user, and enhance the stability and structural integrity of the mattress when filled with water. Those portions of the water fillable bed mattress at which components are joined are thus subjected to less pressure and stress and, consequently, the threat of water leakage is minimized. In certain embodiments, at least one longitudinal partition is also disposed within the water fillable mattress to isolate water disturbances in one set of transverse partitions from propagating to another set of transverse partitions, if any. The longitudinal partition is formed with water openings spaced in offset manner.

Abstract: An improvement for a water bed includes a pair of water bed mattresses housed in a bed cover. There is a heat insulating foam or air bag sandwiched between the two water bed mattresses. Each water bed mattress has a plurality of transverse partitions to reduce water vibration and turbulence therein. The disclosed structure has the advantage of not only improving the stability, but also lengthening the durability of the water bed mattress. A plurality of longitudinal air tubes run through the transverse partitions and communicate with an air bag for providing a desired softness of the water bed mattresses to suit an individual user's requirements. Moreover, the disclosed water bed mattress is able to support a user's back bone comfortably, and minimize the quantity of water used for the mattress to reduce its weight.

Abstract: A water bag for a water bed, including a hollow shell dividing into two inflating chambers at two oposite ends and a plurality of transverse water chambers between the inflating chambers, and a plurality of air bags longitudinally mounted in the transverse water chambers in parallel and respectively connected between the inflating chambers.

Abstract: A water bed which includes a soft frame; a peripheral air bag mounted within the soft frame; a water bag mounted within the soft frame and surrounded by the peripheral air bag, the water bag comprising three pairs of opposing plastic lining walls sealed together, at least one water valve for permitting water to be filled into the water bag, and a plurality of through holes through the plastic lining walls for the passing of water, the plastic lining walls including a top plastic lining wall and a bottom plastic lining wall, each of the top plastic lining wall and bottom plastic lining wall of the water bag having two sealing lines at two opposite sides respectively sealed to respective outer side edges of a respective sides of the periphery air bag; an intermediate air bag mounted within the water bag, the intermediate air bag comprising at least one air valve extending out of the water bag and the soft frame, a plurality of partition stretchers, each of the partition stretchers having at least one air hole,
