Definitions

  • 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.
  • 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.
  • 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.
  • the body 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.
  • FIG. 1 shows a diagrammatic transversal cross-section view of the device in this invention.
  • 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.
  • FIG. 1 consists of an elongated recipient 1 of rectangular shape, its ledge 2 and 2', the membrane 3, the flotation generation element 4, and the base mattress 5.
  • FIG. 2 consists of the recipient 1, its ledge 2 and 2', the fluid 4, the base mattress 5 and the main mattress 6.
  • FIG. 3 consists of the recipient 1, its ledge 2 and 2', the membrane 3, the fluid 4 and the base mattress 5. It shows a man lying down during its utilization.
  • FIG. 4 consists of the recipient 1, the fluid 4, the base mattress 5, and a number of sections 7.
  • FIG. 5 consists of the recipient 1, the base mattress 5, the capsules, bubbles or bags 8. It shows a type of device during its utilization.
  • FIG. 6 consists of the recipient 1, the membrane 3, the base mattress 5 and the capsules, bubbles or bags 8.
  • FIG. 7 consists of the fluid 4, the dense core 9 and its external membrane 10.
  • FIG. 8 consists of the fluid 4, its external membrane 10 and the powder particles 11.
  • FIG. 9 consists of the fluid 4, the external membrane 10 and the metallic balls or sand 12.
  • FIG. 10 consists of the base mattress 5 and a number of independent vertical sections connected at the base 13.
  • FIG. 11 consists of the ledges 2, the fluid 4, the base mattress 5, the main mattress 6, the recipient seat 14, the pillow extension of the mattress 15 and the leg 16.
