1. Field of the Invention
The present invention relates to a mattress, particularly an adjustable mattress with supporting force regulated by second flexible members.
2. Description of the Prior Art
A case for a mattress's supporting force regulated with second flexible members shown in the patent application Ser. No. 12/877,275, MATTRESS STRUCTURE (hereinafter referred to as cited case 1), submitted on Sep. 8, 2010. Cited case 1 has major features as follows: A mattress structure is a mattress body and comprises: a fixed plate, which has a plurality of flexible accommodating holes and at least one first flexible member; a moving plate, which has at least one second flexible member corresponding to the flexible accommodating hole, the moving plate is below the fixed plate and has a distance with the fixed plate for moving; at least one lifting device, which is combined with the bottom of the moving plate, the moving plate and the second flexible member move up and down via the lifting device in order to let that the second flexible member penetrates through the flexible accommodating holes and protrudes out of the top surface of the fixed plate.
The patent application herein which is different from cited case 1 is to combine and accommodate first flexible members and second flexible members in a carrier and each of the first flexible members and each of the second flexible members are encased in packages to become a flexible support unit. In a regular state, one of the first flexible members sustain weight of the bed surface by means of two bearing points in a stretchable direction contacting both the bed surface and the bottom surface; one of the second flexible member allows its bottom to protrude from or be concealed in the carrier's bottom surface regularly. In addition, the bottom surface of the carrier can be a wire netting structure and each of the first flexible members is fastened to the bottom surface by means of fastener components without exposure of the first flexible member due to the shifted package.
