A tensioning member (111) for an inflatable product is delineated. The tensioning member (111) comprises a base (11) and a plurality of protrusions (12). The plurality of protrusion (12) are coupled to the base (11). Each protrusion of the plurality of protrusions (12) extends from the base (11) in a same direction and are spaced apart from one another. A method for manufacturing the tensioning member (111) and a method for manufacturing an inflatable product including the tensioning member (111) are also disclosed herein.

The present invention discloses an air bed including a mattress body formed by a top surface, a bottom surface and a side wall. The mattress body is provided with at least two layers of side walls being an inner side wall and an outer side wall respectively. The inside of the inner side wall forms a bed air chamber of the mattress body. A side wall air chamber of the mattress body is formed between the inner side wall and the outer side wall. The inside of the side wall air chamber between the inner side wall and the outer side wall is connected with a plurality of side wall drawstrings. The side wall drawstrings form a bed edge of the mattress body with the inner side wall, the outer side wall, and the side wall top surface/side wall bottom surface respectively.

An air mattress includes an inflatable chamber. The inflatable chamber defines a groove for fixing a fitted bed sheet. The fitted bed sheet has an elastic edge. The elastic edge of the fitted bed sheet is placed to engage the groove so as to keep the fitted bed sheet in place when the fitted bed sheet is stretched over the inflatable chamber.

The disclosed technology includes an internal support structure for providing structural stability to an inflated air mattress. The internal support structure can include a loop of material and attachment strips to attach the loop to the top and bottom panels. The internal support structure can also include attachment strips to attach the ends of the loop of material together to complete the loop. The air mattress can include a plurality of internal support structures.

The present invention relates to the technical field of air cushion beds, and discloses a double-layer air cushion bed, including an upper air chamber, a lower air chamber, a middle partition sheet arranged between the upper air chamber and the lower air chamber, and an inflating structure, where the middle partition sheet is provided with a communicating structure for communicating the upper air chamber and the lower air chamber to allow air in the upper air chamber and the lower air chamber to circulate with each other, and the inflating structure is configured to inflate and deflate the upper air chamber and the lower air chamber. Through this arrangement, the upper air chamber and the lower air chamber are configured as an upper layer and a lower layer, and the communicating structure on the middle partition sheet communicates the upper air chamber and the lower air chamber to form a large convective air chamber. The upper air chamber and the lower air chamber can be inflated using the inflating structure, thereby solving the problems that in the prior art, the layers of the double-layer air cushion bed are independent of each other, each layer requires the inflating structure such as an inflating nozzle or a built-in inner pump and needs to be inflated separately during inflation.

A transfer mattress includes a top panel, a bottom panel, an outer stringer and an inner stringer. The top panel has a perimeter including a proximal edge and a distal edge, wherein a central longitudinal axis extends from the proximal edge to the distal edge. The bottom panel has a plurality of perforations and a perimeter including a proximal edge and a distal edge coupled to the perimeter of the top panel. The outer stringer and inner stringer each have a superior edge coupled to the top panel and an inferior edge coupled to the bottom panel and a longitudinal portion that is substantially parallel to the central longitudinal axis. The inner stringer is positioned between the central longitudinal axis and the outer stringer.

A welding process of an inflatable product is provided that includes using isolating members between first and second portions of weldable tensioning members to resist the first and second portions of the weldable tensioning structures being welded together during welding of the first portions to a first sheet of weldable material and welding of the second portions to a second sheet of weldable material.

The disclosed technology includes an internal support structure for providing structural stability to an inflated airbed. The internal support structure may include an internal support wall connected to side panels by one or more side support beams. The internal support structure may further include corner support walls and a plurality of internal support beams to provide additional support.

An apparatus is configured for use with a chair having a supporting surface, and includes a bottom member adapted to be placed above the supporting surface of the chair. The bottom member includes a cushioning member in the form of a bladder. The bladder includes at least two internal chambers. A first of the at least two internal chambers extends from a rear edge disposed inwardly proximate a center of the bladder and a second of the at least two internal chambers extends peripherally around three inner sides of the first internal chamber. The apparatus further includes a top member having a bottom surface positioned in confronting relation to the bottom member and a top surface opposite the bottom surface.

A method for installing a universal air handler for a building air conditioning system includes installing a compact outdoor cabinet having a blower and separate intake and outlet chambers separated by an evaporator core. Cool and return air ducts from the building couple to each chamber. Return air drawn by the blower into the return air chamber passes across the evaporator, then through the blower and out through the cool air duct. Coolant lines couple the evaporator to a nearby stand-alone condenser/compressor unit. In one embodiment, an adapter enables stacking the condenser/compressor unit atop the cabinet to reduce the footprint of the combination. In another embodiment, a manifold couples permanently to the building air ducts and releasably couples to the cabinet. The universal air handler easily decouples from the manifold for transportation and maintenance. The manifold may be installed in various locations around the building, including on the roof.
