Problems solved by technology

As a consequence, the user will have to reserve more space for the storage of the pumps, which is quite a waste to space especially in urban areas.
Further, once the pump is out of order, the inflatable product is useless such that the user will need to maintain the pump to be active and efficient for whenever needed.
The labor and energy to maintain the pump efficient to fulfill the requirements are a drain on the time and resources of the user of the inflatable product.

Embodiment Construction

[0012] With reference to FIG. 1 and taking FIG. 4 for reference, the self inflatable mattress (1) of the present invention has a first chamber (110) defined in a main portion (11) of the inflatable mattress (1) and a second chamber (20) defined in an extended portion (2) which is integrally formed with the main portion (11). The first chamber (110) and the second chamber (20) are isolated and enclosed by a covering (13).

[0013] A valve (12) is provided on the main portion (11) of the inflatable mattress (1) and a unidirectional valve (3) is provided on the extended portion (2) and sandwiched between the first chamber (110) and the second chamber (20). It is noted from FIG. 4 that a portion of the first chamber (110) extends into the second chamber (20) so that the unidirectional valve (3) is sandwiched between the first chamber (11) and the second chamber (20). However, it is possible that a portion of the second chamber (20) extends into the first chamber (110) and still the unidir...

Abstract

A self inflatable mattress includes a main portion with a first chamber and a sponge in the first chamber, an extended portion and having a second chamber, a valve mounted on the main portion to allow surrounding air to enter the first chamber and a unidirectional valve received in the extended portion and sandwiched between the first chamber and the second chamber to provide alternate communication between the first chamber and the second chamber. A self expansion of the main portion due to the automatic expansion of the sponge from a compressed state to a non-compressed state allows the surrounding air to enter the first chamber, the air inside the first chamber is able to be forced to enter the second chamber by pushing away the unidirectional valve to resume communication between the first chamber and the second chamber so that the second chamber is inflated.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a self inflatable mattress, and more particularly to a self inflatable mattress having at least a first chamber and a second chamber isolated from the first chamber. A valve is mounted on the first chamber to allow air from the surrounding environment to enter the first chamber due to the self expansion of a sponge in the first chamber and a unidirectional valve is sandwiched between the first chamber and the second chamber to allow the air from the first chamber to enter the second chamber so that the mattress is able to fulfill the requirement of self inflation. [0003] 2. Description of Related Art [0004] It is noted that the inflatable product in the market requires a pump to inflate / deflate the inflatable product and so the pump is a necessity to inflatable products. Therefore, the user will have to purchase a pump in addition to the inflatable product and prepare a space for sto...
