Abstract

A floating lift system for beds, seats and the like comprising a stretched recipient, open at the top, containing a fluid or flotation generation element of density between 1 and 2 approximately, and covered by a flexible, elastic, loose membrane, having an additional lift component added to the base in the form of a thin foam rubber mattress.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention
In elements for rest, repose, convalescence, etc., such as beds, seats and the like.
2. State of the Prior Art
Existing beds use mattresses either of the fluff or air or water type, all of which carry body weight under pressure from below in a manner which is partial, uneven and anatomical particularly for bones which increase such disproportion or unevenness in such pressure, to create points of extreme pressure and the associated discomfort, pain, poor circulation, etc., particularly if some physical problems or injury is involved. The same occurs with seats and the like.
BRIEF DESCRIPTION OF THE INVENTION
The floating lift system for beds, seats and the like in this invention consists of a stretched recipient, open at the top, containing a fluid or flotation generation elements of specific density between 1 and 2 approximately, and can be covered by a flexible, elastic loose membrane. An additional lift component is added to the base in the form of a thin foam-rubber mattress.
The flotation erements may be contained partly in a mattress which is itself housed in a container.
The container may take the external form of the cover or outside surround of a seat, open at the top.
The flotation element may be a fluid.
The container base may have a transversal cross-section curved in the shape of a tile making it possible to reduce the total amount of fluid or capsules to be used, and it may have foam rubber or inflatable tube-shaped edges.
It may also take the form of a mattress and be made up of a number of independent vertical sections connected at the base.
A variant consists of multiple blisters partly linked together and which, as a whole, take the form of a mattress, with transversal tile-shaped cross-section.
The containers may house or contain a flotation element in the form of multiple flexible capsules also partially filled with fluid which, in turn, may contain a dissolved solid.
Said capsules may consist of a flexible surround containing a dense core and mixture of liquid and a solid element in the form of powder, balls, sand, etc. This mixture makes it possible to obtain a component with some properties similar to those of very high-density liquids, without dampness or without direct contact between the user and the liquid.
The base foam rubber mattress not only supports but also dampens and prevents excessive movement by the user, and may have projections or protuberances on the upper surface.
The mattress fitted on the base, made of foam rubber or any other flexible fibre may have a pillow at one end made of the same material. Said mattress may be made up of a number of foam rubber portions linked together at the base.
If capsules are also used, they may be covered over as a whole by a membrane.
The surface of said membrane, which is highly elastic, may be undulating or made up of a number of projections or hemispherical cavities.
The fluid, which is cheap, harmless, non-toxic, non-inflammable and non-pollutant must, in some cases, be electrically insulated, or may be water, water with soluble dense solids such as sugars, salts, etc. and, in the case of capsules, liquids and non-soluble solids, to which small quantities of preservative products may be added. The fluid may be heated or cooled with safe convection, radiation or other systems.
A device and hydraulic pump can be employed to cause the fluid or flotation element and therefore, the body to vibrate, with application at specific points.
Both mattresses and capsules must be partly filled with fluids or other elements so that, as a whole, they will act like a fluid and mould to objects in contact with them.
OPERATION
When the body lies or is prone on the water-proof membrane or fabric, the body is lowered into the fluid, moving the wall of the capsules, membrane or fabric to adhere or adopt to the body laterally and below, until the body weight is the same as the upward lift of the fluid, at which point it remains static or balanced. In other words, an ideal flotation system is obtained without needing to wet the body. If the drop of the body is excessive, the wall of the capsules or the membrane create a concave form against the body, lifting it as greater flotation is created. When capsules are used without the upper membrane, said capsules behave in the same way.
BENEFITS
This is the only system which uses flotation for these rest components. With this system, the pressure from the flotation generation element on each of the various parts of the body is the same as the pressure of the body, so that they are counteracted or eliminated. It is not possible to obtain a better anatomical adaptation. On the other hand, the surface on which the body rests is maximum so that the pressure at specific points on the body, to support it, is minimal. Lift or suspension is obtained without eliminating gravitation, which is necessary to the organism. It is simple, economical and comfortable, enhances blood circulation, avoids pain at certain points as well as spinal deviations and allow body vibration to be applied.
BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 2 to FIG. 6 show a diagrammatic transversal cross-section views of different variants of the invention.
FIG. 7 to FIG. 9 show cross-section views of multiple capsules, bubbles or bags of the invention.
FIG. 10 shows a transversal cross-section view of a variant of the type of mattress fitted on the base. This allows a better stability to the user.
FIG. 11 shows a longitudinal cross-section view of a set type variant in the invention.
