1. Field of the Invention
The present invention relates generally to air mattresses and more specifically it relates to a multiple position air mattress system for achieving various support positions.
2. Description of the Related Art
Air mattresses have been in use for years. A conventional air mattress is comprised of a rectangular flat structure that is inflatable forming a bed-like structure. Conventional air mattresses may have pumps built into them or may be inflated from an external air source. Conventional air mattresses are not capable of being positioned in more than a prone bed position. The present invention overcomes the inherent limitations contained within conventional air mattresses.
In view of the foregoing disadvantages inherent in the known types of air mattresses now present in the prior art, the present invention provides a new multiple position air mattress system construction which can be utilized for achieving various support positions and support functions.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new multiple position air mattress system that has many of the advantages of the air mattresses mentioned heretofore and many additional features that result in a new multiple position air mattress system.
Thus, a primary object of the present invention is to provide a multiple position air mattress system that will overcome the shortcomings of the prior art devices.
Another object is to provide a multiple position air mattress system for achieving various support positions.
A further object is to provide a multiple position air mattress system that may form into various positions such as but not limited to a chair, a recessed lounge, a prone bed and an adjustable lounge.
An additional object is to provide a multiple position air mattress system that is efficient and easy to utilize.
A further object is to provide a multiple position air mattress system that may be stored in a compact storage position.
In accord with these objects, the present invention generally comprises a first relatively larger mattress, a second relatively smaller mattress mechanically coupled to the first mattress, and a bellows unit attached to the second mattress. Each of the first mattress, second mattress, and bellows unit is preferably separately inflatable through separate valves. A pump unit is provided for supplying pressurized air to the first mattress, the second mattress and the bellows unit.
With the first relatively larger mattress, the second mattress and the bellows, the mattress system of the invention can be utilized to implement a chair, a recessed lounge, a prone bed and an adjustable lounge. In particular, with the bellows deflated, and the first and second mattresses longitudinally adjacent each other, the system implements a prone bed. With the bellows unit inflated and atop the second mattress, the system implements a recessed lounge. With the bellows unit inflated and below the second mattress, the system implements an adjustable lounge. With the bellows unit inflated above the second mattress, and the first mattress located under the second mattress, the system implements a chair.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and that will form the subject matter of the claims appended hereto.
In this respect, before explaining at least one embodiment of the invent ion in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of the description and should not be regarded as limiting.
Other objects and advantages of the present invention will become apparent to the reader and it is intended that these objects and advantages are within the scope of the present invention.
To the accomplishment of the above and related objects, this invention may be embodied in the form illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustrative only, and that changes may be made in the specific construction illustrated and described within the scope of the appended claims.
In the drawings, like reference characters designate the same or similar parts throughout the several views.
A. Overview
Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views,
A. First Mattress
B. Second Mattress
The second mattress 40 is preferably pivotally connected (via hinge member 30) to the first mattress 20 as best illustrated in
If desired, the second mattress 40 may be fluidly connected (via a tube—not shown) to the first mattress 20 to allow for simultaneous inflation and deflation. However, in the preferred embodiment of the invention, the second mattress 40 is not fluidly connected to the first mattress 20 and is inflated separately by the pressurized air source. This permits the first and second mattresses to be inflated to different pressure levels, which is desirable in providing desired support levels to different parts of the body. For example, because the human torso weighs considerably more than the legs, it may be desirable to inflate the second mattress to a higher degree than the first mattress, thereby providing more support to the torso.
C. Hinge Member
A hinge member 30 is preferably attached between the first mattress 20 and the second mattress 40 for pivotally sup porting the same as best illustrated in
D. Bellows Unit
The bellows unit 50 is attached to the second mattress 40 as illustrated in
The bellows unit 50 preferably has a U-shaped structure which is highest at the back, and which tapers down in the front. The bellows unit, when completely inflated, is approximately twenty-three inches high at the back, and approximately ten inches high at the front of the arms. The arms are about five inches wide at the front (although they are preferably radiused with a radius of between 2 and 2.5 inches at their very front end), and they taper in width as they extend backwards such that the back of the bellows unit 50 is about twelve inches wide. From the tip of the arms to the back of the back, and from the outside of each of the arms, the U-shaped bellows unit 50 is approximately the same size as the second mattress 40; i.e., about thirty-nine inches across the arms and thirty-three inches from front to back.
When located under the second mattress and inflated, the first bellows 52 and the second bellows 54 elevate the second mattress 40 to a desired angle (preferably from zero degrees up to forty-five degrees) with respect to the first mattress 20 as best illustrated in
In the preferred embodiment of the invention, the first and second bellows 51, 52 are fluidly coupled to one another via a number of non-valved flow paths. The bellows 51, 52 receive pressurized air from the pressurized air source via valve 51 such that they are inflated at substantially the same pressure. The extent of inflation of the bellows unit 50 is preferably controllable by the user. Alternatively, if desired, the first bellows 52 and second bellows 54 may be inflated to different pressures. This feature may be controlled by a valve (not shown) that fluidly couples the two bellows 52, 54, or by realizing the two bellows 52, 54 as two distinct air chambers that are pressurized independently from one another. Moreover, it is contemplated that the shape and structure of the bellows unit 50 may be changed as desired.
According to another embodiment of the invention shown in
E. Valves
In the preferred embodiment of the invention, each of the mattresses and the bellows unit is provided with its own respective inflation/deflation valve 21, 41, 51. An additional valve (not shown) may be provided to inflate the second bellows 54 separately from the first bellows 54 if they are not fluidly connected.
F. Pump Unit
As shown in
G. Operation
The present invention preferably has four main positions: a chair position, a recessed lounge position, a prone bed position and an adjustable lounge position. In use, the user first determines what position they desire. Regardless of the position desired, the user preferably inflates the first mattress 20 and the second mattress 40 as shown in
If the user desires to have a chair posit ion, a recessed lounge position or an adjustable lounge position, the user then inflates the bellows unit 50 to a desired level. For example, if an adjustable lounge is desired the user may only inflate the first bellows 52 and not the second bellows 54 or alternatively only partially inflate the bellows unit 50 to achieve a desired height and angle for the second mattress 40 as illustrated in
In yet another alternative embodiment shown in
While specific sizes, materials, shapes, forms, functions and manners of operation, assembly and use have been provided, it will be recognized by those skilled in the art that they may be varied, and all equivalent structural variations and relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. Any headings utilized within the description are for convenience only and have no legal or limiting effect. Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
