Definitions
- the present invention relates to a Gutkern divellsystem for furniture, especially mattresses and seating, but also car seats and camping furniture, which have an air-filled core.
- water beds have several disadvantages. Physically weak persons have difficulty changing their reclining position. This is due to the fact that the water in the mattress must be moved under the body at a position change at the same time. For babies such mattresses are therefore even dangerous. Other disadvantages are the comparatively complicated handling and the very large weight. It has proven to be particularly problematic that water is a good heat transfer medium. The water filling which nor ⁇ mally has a maximum room temperature, must be at least constantly heated to a temperature of about 25 0 C to 28 0 C, not to escape to the body in an unpleasant manner and especially harmful to health temperature. However, such temperatures are absolutely harmful to persons with venous disorders.
- tempering devices can be dispensed with in mattresses with an air core, without having to give up the known advantages of the water beds. All other disadvantages of a waterbed can be avoided by using a mattress with air core.
- a more optimal adaptation of the Auf ⁇ position to the body shape of the user since it does not come to a lateral displacement of water as the waterbed, but the displaced air flow leads to a uniform increase in the air pressure over the entire volume.
- a disadvantage of seating or mattresses with air core is that they are not completely gas-tight. Gas diffusion, in particular under pressure during use, results in a pressure loss in the air core, which requires periodic refilling.
- older systems have filling systems driven manually or by means of an electric motor in order to be able to keep the once selected degree of hardness essentially constant for an indefinite period of time.
- a Luftkernhellsystem is known with a fold-out integrated pump, which is connected via a check valve directly to the air core. To refill the air core, the pump is unfolded and compressed manually. It may be relatively easy that the air core is overfilled and too hard, so in turn air must be drained through another valve. This cumbersome operation was therefore soon replaced by systems in which the air can be filled via a control valve only up to a preset pressure.
- EP 0 620 716 B1 describes an upper mattress with an integrated air system, in which there is an encircling foam frame around an air core, in which an air storage and supply system is integrated.
- Die ⁇ ses consists of an air pump, an air reservoir and a pressure regulating valve.
- Die ⁇ ses When loading the foam frame - the user sits down on the mattress - creates a pressure on the pum ⁇ pum body integrated in the foam frame, which promotes the air from these pump bodies in an air reservoir be ⁇ . There, the air coming from the pump bodies is compressed and stored. Between the pump bodies and the reservoir, a return check valve is installed in the connecting line.
- the pressure from the air reservoir equalizes the pressure in the air core of the mattress again to a value which is set on the pressure regulating valve.
- the pump bodies suck in ambient air via another valve by returning them to their starting position.
- a further disadvantage is that the reservoir must always be under pressure in order to be able to keep the air core of the mattress at the set value. However, if, for some reason, for example due to the entry of dust into the check valve to the reservoir, there is a pressure reduction in the reservoir, it is impossible to maintain the set pressure value. On the other hand, the built-up pressure of the compressed air can only be reduced via the air core. This has the consequence that in the reservoir with intensive use can easily build up a pressure of 100 mbar and more, causing the Ports and valves are subjected to a high load.
- Another disadvantage is the enormously long distances from the air inlet to the reservoir and on to the pressure regulating valve, which creates large gas diffusion surfaces. Also increases the risk of leakage due to the numerous connection points. Another disadvantage is that a desired pressure reduction in the air core is possible only by diffusion loss, which is why it takes a very long time until the pressure in the air core has adjusted to the lower level.
- the present invention therefore has the object of avoiding these disadvantages by providing a pumping and control system which operates without a reservoir and has the same pressure in the entire air core filling system when not loaded as in the air core.
- This object is achieved by the technical features described in the main claim.
- the air supply system according to the invention should have a considerably smaller design with considerably reduced connecting lines and also have a smaller number of connection points in comparison to the system of EP 0 620 716 B1, in order thereby to reduce the risk of unintentional pressure reduction.
- the figure shows the basic structure of the invention.
- the entire Vor ⁇ direction has with the enclosing them - not shown here - housing on a size that makes it possible to install the housing, for example, in the region of the head or foot of a mattress.
- the essential core of the invention is the pumping system, which is shown here by way of example as a two-chamber bellows, and the control system operatively connected to the pumping system. It goes without saying, however, that the same invention is also made possible by alternative technical embodiments, in which a chamber containing the displacement air from the air core and a suctioned outside air are in direct operative connection and are simultaneously and almost completely emptied via the return device become.
- the present invention therefore also encompasses such technical configurations.
- the air is forced out of the air core (not shown) via the connecting line 1 into the first chamber 2 of the two-chamber blowing bellows 3, whereby the bellows 3 stretches and with its outer surface 4 against a restoring spring 5 suppressed.
- the volume of the centrally arranged second chamber 6 is also forcibly increased, as a result of which a negative pressure is created which leads to an intake of ambient air via the line 7.
- This Lei ⁇ device 7 is via a check valve 8 with the connecting line 9 to the outside air and connected via another check valve 10 with line 1.
- the Ver ⁇ connection line 9 is an air filter 11, which reliably prevents the entry of even the smallest dust particles, which could affect the functioning of the return check valves.
- the return spring 5 has a pressure force which is approximately 1 mbar to 5 mbar, preferably approximately 2 mbar to 4 mbar, above the normal pressure of the air core.
- a flow restrictor 12 In front of the check valve 10 is a flow restrictor 12 to allow a slow pressure build-up in the air core up to that value which is predetermined by the pressure regulating valve 13. Exceeding air escapes at the Druckregulier ⁇ valve 13 via the air outlet opening 18. By this construction prevails in the entire system of the preset normal pressure of the air core.
- the pressure regulating valve 13 is designed as a conventional diaphragm valve, wherein the pressure diaphragm 14 should have as large a surface as possible, since the accuracy of the pressure setting is directly related to the diaphragm surface. Experiments have shown that the desired accuracy leads to satisfactory results for membrane diameters of about 30 mm to 50 mm.
- an overpressure valve 15 connected to the line 1 opens immediately and can be set, for example, to a limiting pressure of about 60 mbar or 70 mbar. This can prevent any damage caused by excessive pressure.
- the originally selected normal pressure of the air core was chosen too high.
- the normal pressure of the preferably unbelas ⁇ teten air core can be reduced to any, lower value in a short time.
- the valves 8, 10, 15 and 16 are preferably designed as diaphragm valves, de ⁇ ren membrane surface diameter in the range of about 0.5 cm to 2 cm, preferably is about 1 cm, wherein the membrane thickness has a thickness of about 0.2 mm to 0.4 mm, preferably about 0.25 mm.
- the particular advantages of the air core filling system according to the invention are, on the one hand, that the automatic air replenishment is independent of the respective load point of the air core, since any load leads to a Ansau ⁇ supply of fresh air, which in particular in air cores a significant Ver ⁇ improvement in reliability over brings known devices with it.
- Another advantage is the considerably reduced construction and the first possible, very short connecting lines. It is also advantageous that no memory with precompressed air is required for refilling the air core. The risk to the components and their joints by a possible build-up of excessive pressure in the air storage chamber is reliably avoided because the subject air storage chamber, from which the make-up of the air core is done with fresh air, maximum atmospheric pressure.
