AI Technical Summary

Benefits of technology

The invention is an air mattress that includes an inflatable bladder, a pump, and a controller. The controller activates the pump when a timer expires. This allows for controlled inflation of the bladder and provides a more comfortable and adjustable air mattress.

Problems solved by technology

However, airbeds tend to lose some amount of pressure once inflated.
Such loss of pressure may be cause by a slow leak, or by a stretching of the bladder material.
Loss of pressure is felt by users as a lack of support from the airbed, and is undesirable.
While the primary pump can inflate or deflate the airbed quickly, it is generally loud and imprecise.
However, this type of pressure management generally cannot be programmed.
In addition, due to tolerances of the pressure controlling assemblies, this type of pressure management is typically of poor accuracy and performance in maintaining pressure in the airbed.

Embodiment Construction

[0017]In the following description, various embodiments of the present invention will be described. For purposes of explanation, specific configurations and details are set forth in order to provide a thorough understanding of the embodiments. It will also be apparent to one skilled in the art, however, that the present invention may be practiced without the specific details. Furthermore, well-known features may be omitted or simplified in order not to obscure the embodiment being described.

[0018]Referring now to the drawings, in which like reference numerals represent like parts throughout the several views, FIG. 1 shows an airbed 20 in accordance with an embodiment. The airbed 20 includes a top 22 and a bottom (not shown). The top 22 and the bottom are connected by one or more than one sidewall 24. Together, the top 22, the bottom, and the sidewall 24 form an enclosed space, or air bladder, which may be inflated so that the airbed 20 may be used as a mattress in a manner known in ...

Abstract

An air mattress comprising an inflatable bladder, at least one pump, a controller, and a timer. The inflatable bladder includes at least one inner chamber. The at least one pump is in fluid communication with atmosphere, as well as the at least one inner chamber of the inflatable bladder. The controller is in communication with the at least one pump, as well as a time. The controller causes activation of the at least one pump upon expiration of the timer.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 62 / 669,464, filed May 10, 2018. The entire disclosure of said application referenced above is incorporated herein by reference.FIELD OF INVENTION[0002]The present invention relates generally to an air pump for inflatable bladders. More particularly, the present invention relates to an air pump for air mattresses that automatically maintains a desired pressure within the air mattress.BACKGROUND OF INVENTION[0003]An airbed, sometimes called an air mattress, is a large rectangular rubber or plastic (e.g., vinyl) bag that is filled with air so that it may be used as a bed. Airbeds are well known in the art, and have proven themselves to be very useful. On the one hand, an inflatable airbed may be deflated and folded to store the airbed in a closet or basement. On the other hand, when a guest is in need of a place to sleep, or when the owner of the airbed takes a trip to a...
