20080209642 | AIR-INFLATED MATTRESS - An air-inflated mattress, comprising a top layer, an outer shroud band, a plurality of anchor separators and a bottom layer, wherein said shroud band connects the top and bottom layers together to form an inflatable bladder. A middle layer below said top layer is partially sealed to the top layer to form a plurality of sealed or half-sealed cavities, in which some or all of said cavities are in fluid communication with the inflatable bladder, via a plurality of air vents in the middle layer, creating air-pockets arrayed on the top surface of the air mattress. The mattress may also comprise a middle shroud band and an inner shroud band, with a plurality of joint spots welded between the shrouds, creating a plurality of half-sealed cavities on the surface of the outer shroud band, with means to pass air between the inflatable bladder and the cavities, which slows the spreading speed of the air to the bladder and the cavities, so that the air mattress is even and level and the supporting strength of the air mattress is greatly improved. | 09-04-2008 |
20080209643 | AIR-INFLATED MATTRESS - A double air-inflated mattress having an upper chamber and a lower chamber, the upper chamber having a top layer, an outer shroud band, a plurality of anchor separators and a bottom layer, the outer shroud band connecting the top and bottom layers to form an inflatable bladder; a middle layer below said top layer partially sealed to the top layer to form a plurality of sealed or half-sealed cavities, in which some or all of said cavities are in fluid communication with the inflatable bladder, the lower chamber having a top layer, an outer shroud band, a plurality of anchor separators and a bottom layer, said outer shroud band connecting the top and bottom layers to form an inflatable bladder. Each chamber of the double mattress may also have a middle shroud band and an inner shroud band, both of said middle shroud bands being separately welded to the outer shroud bands and the inner shroud bands to form a plurality of closed or half-closed cavities, some or all of said cavities being in fluid communication with its respective inflatable bladder to form a plurality of air pockets on the outer shroud bands of the double air mattress. | 09-04-2008 |
20090044342 | Inflatable massaging mattress - An inflatable massaging mattress, comprising: —an air compressor ( | 02-19-2009 |
20090064417 | LIFTING DEVICE - A device for lifting a person from a supine position into a raised supine position or sitting posture. The device comprises at least one U-shaped inflatable structure which defines a hollow and a flexible membrane which is attachable to the device. The membrane is extendable over at least a portion of the hollow to provide a support surface for the person. | 03-12-2009 |
20100043148 | AIR MATTRESS INTERNAL SUPPORT STRUCTURE - An air mattress having an internal support structure for stabilizing and resisting deformation of a sleep surface. The air mattress includes an air bladder defined by an upper sleep surface, a bottom surface, and an interconnecting side wall. A plurality of support columns interconnect the upper sleep surface to the bottom surface and segment an interior cavity of the air bladder into a plurality of air chambers for receiving air to support the upper sleep surface. A resilient member is carried within each of the air chambers to stabilize and resist deformation of the upper sleep surface resulting from changes in air pressure within the air bladder and from the shifting of weight on the upper sleep surface. | 02-25-2010 |
20110191961 | ECOLOGICAL AIRBED - An ecological inflatable airbed comprises a main body, a plurality of rings, and an air faucet. The main body is made by non-woven fabric and Ethylene Vinyl Acetate copolymer. A space is defined within the main body. The main body is inflatable, and has a top layer and a bottom layer. The non-woven fabric is laminated to a layer of Ethylene Vinyl Acetate copolymer which is laminated to a polyester mesh. A plurality of interstitial flaps have connection between the top layer and the bottom layer. A plurality of loop connection areas are arranged within the space defined in the main body. An air valve is provided on the main body for inflating or deflating the main body. The air valve forms an airtight seal with the main body for retaining air within the main body. | 08-11-2011 |
20130145560 | AIR MATTRESS - An air mattress including an inflatable compartment, strips, a connecting sheet and pillow strips is provided. The inflatable compartment includes a top wall, a bottom wall and a side wall surrounding peripheries of the top wall and the bottom wall. The strips are air-pervious and disposed in the inflatable compartment, wherein the strips are connected between the bottom wall and the top wall and located in a lying portion of the top wall. The connecting sheet is air-pervious and disposed in the inflatable compartment and facing a pillow portion of the top wall, wherein the connecting sheet is connected between the side wall and the strips adjacent to the pillow portion. The pillow strips are air-pervious and disposed in the inflatable compartment, wherein the pillow strips are connected between the connecting sheet and the pillow portion of the top wall. | 06-13-2013 |
20130180052 | AIR MATTRESS - An air mattress includes an inflatable compartment, strips and decoration strips. The inflatable compartment includes a top wall, a bottom wall and a side wall surrounding the peripheries of the top wall and the bottom wall. The strips are air pervious and disposed in the inflatable compartment. The strips are connected between the top wall and the bottom wall. The decoration strips surround the top wall and are connected between the top wall and the side wall, so that the side wall is formed into a first layer portion and a second layer portion. | 07-18-2013 |
20140237727 | 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. | 08-28-2014 |
20160113411 | METHOD AND APPARATUS FOR WELDING 3D BELLOWS, AND BELLOWS - The present invention relates to a method for welding a 3D bellows. The method includes: repeatedly laminating a unit cell material, a second adhesion-preventing film, a different unit cell material, and a first adhesion-preventing film; forming ventilation holes on the unit cell materials by pressing a hole-processing cutter on which a hole-circumference welding heater is installed onto the laminated unit cell materials and the first adhesion-preventing films, and then heating the circumference of the ventilation holes; finishing two sides of the unit cells by positioning, on two outermost surfaces of the laminated unit cell materials, a first finishing unit cell material and a second finishing unit cell material provided with an air injection port; and cutting the first finishing unit cell material, the unit cell materials, and the second finishing unit cell material and heating the periphery of the cut area by pressing a contour-processing cutter. | 04-28-2016 |
