Beam construction of air mattress

Abstract

The beam construction of an air mattress includes a top sheet, a bottom sheet, and a periphery sheet. Beams are used to connect the top sheet and the bottom sheet. It is further characterized by both ends of the beam having at least one end that has two extended side-parts, with the surface of the extended side-parts connecting with the top sheet or the bottom sheet. The cross-section of the beam may a substantially “” shape, a substantially “” shape, a substantially “” shape, or a substantially “” shape. The advantage of this present utility model is that it has created a connecting area between the beam and the top sheet and the bottom sheet, thus reducing the pulling force at the seam and ensuring the durability of the air mattress.

Description

FIELD OF THE INVENTION[0001]The present utility model relates to one kind of air mattresses, and particularly to the beam construction of air mattresses.BACKGROUND OF THE INVENTION[0002]At present, air mattresses are becoming more and more popular in the market, because they have the advantages of being easily carried and conveniently stored, in addition to being comfortable. People not only use them as spare beds at home, but also for camping and for leisure. The traditional air mattress generally uses an I-shaped or an S-shaped beam, where both ends of the beam may connect with a top sheet and a bottom sheet, respectively. Generally, the beam's section shape is in the form of a “]” or a “Z”. A vertical direction pulling force is created against the top sheet and the bottom sheet after inflation, with more force being exerted at the seam where the beams and the top sheet or the bottom sheet connect. The place where the beams and the top sheet or the bottom sheet connect may easily ...

AI Technical Summary

Benefits of technology

[0005]Compared with the beams of the current and existing technology, the advantage of the present utility model is that it has an added connecting area between the beams and the top sheet and the bottom sheet, thus reducing the pulling force exerted at the seam and ensuring the durability of the air mattress.

Problems solved by technology

The place where the beams and the top sheet or the bottom sheet connect may easily come apart or be torn apart, especially when the interior air pressure value in the air mattress is high, and damage may occur when stronger exterior forces are exerted, which causes a sudden increase in the interior air pressure value.

Although the possibility of damage to the air mattress has been reduced using these methods, production costs have increased greatly.
