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.

Description

BACKGROUND OF THE INVENTION [0001] (a) Technical Field of the Invention [0002] The present invention is related to a pull band for an inflatable air mattress of medium or large size, and more particularly to one that provides an excellent elongation and automatic restoration mechanism. [0003] (b) Description of the Prior Art [0004] Whereas most of inflatable products generally available in the market are for entertaining, sports and leisure activities, the product is inflated without compromising its handy and lightweight features to operate on land or surface. [0005] An inflatable air mattress (A1) of the prior art as illustrated in FIG. 1 of the accompanying drawings having been introduced into the market for many years contains multiple pull rings (A2) and a pull band (A3), both being critical to whether the mattress (A1) maintains its shape in use or not. Those pull rings (A2) are arranged in a check fashion and each is disposed with an air vent channel (A21) to provide air conv...

Benefits of technology

[0011] The primary purpose of the present invention is to provide an improved construction of the pull band in the inflated air mattress that eliminates those flaws found with the prior art. To achieve the purpose, the band of the present invention is made in an integral enclosure as a breakthrough in solving the problem of deformation at four corners of the mattress. Meanwhile, the band is linked either as an entire piece or by section at a certain inclination to guide the pull and the traction otherwise on the top to the sides of the mattress in forming a perfect integrated traction not only to reduce the deformation when the mattress is inflated but also to give automatic restoration for the shape of the mattress. Furthermore, as the mattress is well balanced and stabilized, it offers the optimal resilience and comfort to sleep on.

Problems solved by technology

However, the prior art of the band is found with the following flaws: 1.

Therefore, once the mattress (A1) is inflated, there is the absence of traction on the tope edge and sidewalls of the mattress (A) to pop up to negatively affect the appearance of the entire mattress.
