Abstract
The invention relates to an air mattress comprised of at least one air chamber made of strips of an air-tight, water vapor permeable or water vapor impermeable material that are welded or glued together. The air chamber is provided with a closable valve for letting air in and out, and the air chamber is filled with a down feather material or a synthetic fiber insulation material.
Description
- The present invention relates to an air mattress having the characteristics of the preamble to claim 1.
- Air mattresses comprising at least one air chamber of welded- or glued-together lengths of an air-impermeable, water-vapor permeable or -impermeable material, in which the air chamber is provided with a closable valve for admitting and releasing air, are known. Conventional air mattresses, while indeed comfortable, warm a person only minimally, since the air trapped in the air chambers or air chamber can circulate freely, and thus a great deal of heat is lost through convection. Air mattresses of encased foam are relatively heavy, large when packed, and relatively expensive to produce, since precautions must be taken to prevent problems of delamination of the casing from the foam.
- The object of the present invention is to create an air mattress which minimizes heat loss from convection yet nevertheless is lightweight, can be packed small, and is economical to produce.
- This object is attained with the characteristics recited in claim 1. Advantageous embodiments and refinements of the invention are summarized in the other claims.
- According to the invention, an air mattress, comprising at least one air chamber of welded- or glued-together lengths of an air-impermeable, water-vapor permeable or -impermeable material, the air chamber being provided with a closable valve for admitting and releasing air, is characterized in that the air chamber is filled with a down material or a synthetic fiber insulation material.
- In a preferred embodiment of the invention, the air chamber is subdivided by struts, and these struts are secured to the bottom and top large faces of the air mattress material either directly or via tapes or the like. The struts that keep the filling material in a balanced distribution are preferably air-permeable, in the case of relatively large chambers, and for instance comprise nylon tricot. However, they can also be air-impermeable, if a subdivision into independent chambers is wanted.
- Preferably, the struts or the tapes or the like are welded or glued to the air mattress material. The struts are disposed essentially regularly and are disposed perpendicularly or obliquely to the horizontal surface on which a person lies of the air mattress.
- It is advantageous if the valve or valves is lined with an open-pore material, to prevent the escape of down material or synthetic fiber insulation material. Inflation of the air mattress by mouth is unwanted, because then moisture is introduced into the down material or synthetic fiber insulation material placed inside. In a manner known per se, the valve is a safety valve to prevent the outflow of air. The valve can be connected to a pump device or a bellows device, and this device, in a special embodiment of the invention, comprises a flexible casing provided with an inlet valve, and this casing is filled with an open-pore, self-expanding foam.
- The invention is described in further detail below as an example, in conjunction with a drawing.
-
FIG. 1 shows an air mattress 1, seen in section at the front. The air mattress 1 is filled with afiller material 2 of down or synthetic fiber batting. This filler material is lightweight and can be compressed to an extreme extent, so that if a light casing fabric is selected, the result is a small packed size and low weight. The air mattress 1 is subdivided into uniform ribs by vertically disposedstruts 3, which are joined at the top and bottom to the casing material, for instance by welding. Thestruts 3 serve to keep the filler material in place. - In the embodiment shown, the air mattress is a single-chamber mattress with a
valve 4, so that thestruts 3 comprise an air-permeable material, to allow the mattress to be blown up with air and to allow air to be let out. Advantageously, thevalve 4 is a safety valve with an outflow preventer which can however be opened for packing or to facilitate the compression, or can even be switched over, so that air can only flow out but not in again.
