MATTRESS LIFTER

Abstract

A mattress lifter includes an air bladder sized to fit between a mattress and a mattress foundation, so that when inflated the air bladder lifts the mattress from the mattress foundation sufficiently to allow removal and replacement of bed linens and easy tucking of bedding under the mattress. Height-limiting material within the air bladder limits a height of the air bladder when the air bladder is inflated. An air pump inflates the air bladder by pumping air through a connection hose. When the air pump is turned on, air moves from the air pump to the air bladder inflating the air bladder. When the air pump is turned off, air moves from the air bladder to the air pump so that the air bladder automatically deflates when the air pump is turned off.

Description

BACKGROUND

Mattress technology improvements and improvement in bed technology in general has resulted in safer, healthier and more comfortable rest. Mattress technology improvements often times results in increasing the weight of mattresses. The lifting required to replace bed linens and tucking in bedding under a heavy mattress can be a significant challenge for some.

DESCRIPTION OF THE EMBODIMENT

FIG. 1 shows a top view of a mattress lifter 11 placed on a mattress foundation 10. FIG. 1 is for illustrative purposes and is not scaled to size. Mattress foundation 10 is a mattress foundation for a king bed, a California king bed, a queen bed, a full size bed, a twin bed or some other size bed. Mattress foundation 10 is, for example a box spring. Alternatively, mattress foundation 10 can be, for example, a wood slat support, a metal support, a floor or any surface that supports a mattress.

In the example given in FIG. 1, mattress foundation 10 matches in width and length a mattress 15 (shown in FIG. 2) which will be placed on mattress foundation 10. Mattress lifter 11 is placed on mattress foundation 10 and then mattress 15 is placed on mattress lifter 11. For example, mattress lifter 11 is both narrower and shorter than mattress 15 and mattress foundation 10. This allows a margin 17 between a front (head) of mattress foundation 10 and a front of mattress lifter 11, a margin 18 between a back (foot) of mattress foundation 10 and a back of mattress lifter 11, a margin 19 between a side of mattress foundation 10 and a side of mattress lifter 11, and a margin 20 between a side of mattress foundation 10 and a side of mattress lifter 11.

A typical size for margin 17, margin 18, margin 19 and margin 20 is five inches. This allows for efficient lifting of mattress 15 and for sufficient room to comfortably remove and replace bed linens and easy tucking of bedding under mattress 15.

For example, mattress lifter 11 is an air bladder composed of woven fabric laminate with an air tight surface. Alternatively, mattress lifter 11 could be composed of rubber, plastic, vinyl or another material selected as suitable for flexibility and for being air tight.

For example, mattress lifter is configured to lift mattress 15 between two and three inches. This configuration can include height-limiting material, such as straps or strips, placed along seams 16 of mattress lifter 11 or along other locations inside mattress liter 11. The height limiting material not only limits height but also adds rigidity and stability to mattress lifter 11 and to mattress 15 as mattress lifter 11 raises mattress 15. For example, these straps or strips are either heat or chemically welded to seams 16 of mattress lifter 11 or other locations within mattress lifter 11. Peripheral channels 22 in mattress lifter 11 allow for providing higher lift on the edges of mattress lifter 11. This tends to slightly bend up the ends of mattress 15 over locations of peripheral channels 22. This provides a deeper space to tuck in bedding. Height-limiting material may be included in peripheral channels 22. These height-limiting material can be selected to allow mattress lifter 11 to be inflated to a higher height around peripheral channels 22, that in the area of seams 16.

The height-limiting material prevents mattress lifter 11 from inflating to more than a height of about two or three inches. The straps or strips that compose the height-limiting material are placed close enough to each other, for example within two and one half to three inches of each other, so that lateral creeping in from out of perimeters is substantially avoided. When the height-limiting material is attached to seams 16 of mattress lifter 11 and the straps or strips that compose the height-limiting material are placed within two and one half to three inches of each other, this requires that seams 16 be separated from each other by no more than two and one half to three inches.

An air pump 12 is used to inflate mattress lifter 11. For example, air pump 12 is powerful enough to mattress lifter 11 and thereby raise mattress 15. For example, air pump 12 is low voltage and powered by a transformer suitable to convert an alternative current source to a direct current power source. The voltage and frequency of the current source will depend upon the standards of the country or region. A plug 14 is used to plug air pump 12 into an alternative current power source. Alternatively, air pump 12 may be configured to run on battery power.

A connection hose 13 is flexible and non-collapsing allowing unhindered airflow between air pump 12 and mattress lifter 11. FIG. 2 shows tubing 13 to head (front) of mattress lifter 11. This avoids the bulk of tubing 13 from being felt by a sleeper through mattress 15. Alternatively, tubing 13 can be connected to a foot (back) of mattress lifter 11 or another location.

For example, neither air pump 12 nor mattress lifter 11 have any valve that works to retain air in mattress lifter 11. Thus, mattress lifter 11 inflates when air pump 12 is turned on and automatically deflates when air pump 12 is turned off. The pressure provided by air pump 12 to mattress lifter 11 is carefully selected so that the air pressure supplied by air pump 12 is sufficient to inflate mattress lifter 11, but not sufficient to cause a leak or other failure of mattress lifter 11. For example, air pump 12 is designed to provide an amount of air pressure that is sufficient to inflate mattress lifter 11, but not sufficient to cause a leak or other failure of mattress lifter 11. In an alternative design, a pressure limiter can be included that prevents air pump 12 from supplying air pressure past a predetermined limit to mattress lifter 11. For example, air pump 12 is turned on and off by a switch on air pump 12 or by a remote switch hard wired between air pump 12 and a transformer for air pump 12.

FIG. 2 shows a cut away view of mattress lifter 11 in a fully inflated condition and residing between mattress foundation 10 and mattress 15. Mattress lifter 11 has lifted mattress 15 so that there is sufficient room to comfortably remove and replace bed linens and to easily tuck in bedding under mattress 15.

Height-limiting material 21 is shown to be preventing mattress lifter 11 from inflating to more than a height of about two or three inches. The straps or strips that compose height-limiting material 21 are placed close enough to each other, for example within two and one half to three inches of each other, so that lateral creeping in from out of perimeters is substantially avoided. Strips are, for example, evenly spaced and run in a direction from head to foot of mattress lifter 11. Optionally, additional height-limiting material may be included in peripheral channels 22.

FIG. 3 shows a side view of mattress foundation 10 and mattress 15 when mattress lifter 11 is deflated. As can be understood from FIG. 3, when mattress lifter 11 is deflated, mattress lifter 11 is not visible from a side view. Mattress 15 and the bedding on mattress 15 conform their shape so that mattress lifter 11 is hidden from view.

The foregoing discussion discloses and describes merely exemplary methods and embodiments. As will be understood by those familiar with the art, the disclosed subject matter may be embodied in other specific forms without departing from the spirit or characteristics thereof. Accordingly, the present disclosure is intended to be illustrative, but not limiting, of the scope of the invention, which is set forth in the following claims.
