  • Patent number: 7013513
    Abstract: A waterbed structure according to the invention comprises a water-containing body, long air protection borders, and a bed housing having a frame-shaped protection accommodating chamber. Each of the long air protection borders has transverse pull strips at a side thereof. The transverse strips have side edges thereof molded to side walls of the long air protection borders using high-cycle heat, and are disposed at interiors of the long air protection borders. The bed housing has a frame-shaped protection accommodating chamber, which is provided with at least an aperture at an appropriate position at an inner or outer side thereof for placing the aforesaid long air protection border. Furthermore, the bed housing is devised with attaching devices for joining with a long air protection border, thereby preventing the air protection borders from expanding outward for lengthening usage lifespan of the waterbed.

  • Patent number: 6343393
    Abstract: An improved waterbed having a waterbed mattress and a bed protecting cover with airbag protecting sides. The waterbed mattress has a plurality of internal, transverse partitions welded by high-frequency heat sealing, arranged at intervals in single or double rows, with water openings. When the water is filled and the air is inflated, the partitions buffer the water forces to increase the stability and maintain the bed mattress firm, straight and in shape. The level of compressing force towards the waterbed mattress can be changed by increasing or decreasing the air pressure in the airbag protecting sides to adjust the softness and hardness of the waterbed mattress.
