Inflatable air mattress pull band

Abstract

A pull band for an inflatable air mattress particularly of medium and large sizes to provide for the mattress excellent elongation and self-balanced mechanism is divided into an upper and a lower portions to respectively jointed to the upper and the lower perimeters of the mattress in symmetric, corresponding and inverse fashion to form an enclosure for providing pull strength to regulate the form of and to support the mattress; the band yielding support for the mattress saturated with the air to effectively cope with external pressure for maintaining in shape; and the mattress being automatically restored to its shape once the external pressure is released.

1 . A pull band in an inflatable air mattress is essentially comprised of multiple built-in pull rings and a pull band; wherein the band related to an enclosure of an integral strip in an inclined configuration; an air vent channel being provided at four rounded corners of the band; the upper perimeter of the top edge of the band being shorter than that of the bottom edge of the band; the upper perimeter of the band being jointed to the inner perimeter of the mattress; and the lower perimeter of the band being jointed to that of the girder of the bank to provide traction by inclined joint.  
   
   
       2 . The pull band in the inflatable air mattress of  claim 1 , wherein both ends are jointed to form the enclosure; four rounded corners are jointed in a triangle; and each joint is provided with an air vent channel to give the inclined configuration to the band.  
   
   
       3 . The pull band in the inflatable air mattress of  claim 1 , wherein the enclosure of the band is broken into two identical shorter sections and two identical longer sections that are jointed to one another; each joint is made in an inclined fashion; four rounded corners being each provided with an air vent channel and indicating the same inclined fashion as that of the band.  
   
   
       4 . The pull band in the inflatable air mattress of  claim 1 , wherein the band is applied to a multi-layer inflatable air mattress; the band being arranged in an internally or externally inclined configuration; the band being divided into an upper portion and a lower portion; both portions being respectively jointed to the inner perimeter and the upper girder of the mattress as well as the lower girder and the base perimeter of the mattress in symmetric, corresponding and inverse fashion to provide traction among the layers.
