Embodiment Construction

[0011]As shown in FIG. 1, a beam 4 has a substantially “” shape cross-section. The two ends of beam 4 have extending parts 41 that are connected with a top sheet 1 or a bottom sheet 2, respectively, by adoption of high-frequency welding. After inflation, beam 4 of the air mattress exerts pulling forces against the top sheet 1 and the bottom sheet 2 through both ends of the extending parts 41. The pulling forces against the top sheet 1 and the bottom sheet 2 are dispersed. Simultaneously, the extending parts 41 connected with both ends of beam 4 protect the welded joints A. The place where beam 4 connects with the top sheet 1 or the bottom sheet 2 will not easily peel off or be torn away when pulling forces are brought from vertical directions, even when the interior air pressure value in the air mattress is high, or when stronger exterior forces are exerted, which causes a sudden increase of interior air pressure value.

[0012]The embodiment shown in FIG. 2 is similar to the embodimen...

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 ...
