Definitions

  • the invention relates to a mattress for Lounge furniture with a centrally arranged Air cushion by an elastic Shaped body is surrounded.
  • Mattresses play in the living and sleeping areas of this type compared to mattresses for conventional bed systems a subordinate Role.
  • air beds are suitable to achieve a high level of comfort especially because of the pressure of the air cushion different, i.e. to the needs of the Customized, can be adjusted. This creates significant production and sales advantages because not for each desired degree of hardness has its own mattress must be produced and kept in stock.
  • UNITED STATES 4435 864 discloses an air bed, the Air cushions in the surrounding mattress body is fooled. The benefits of a variable Air pressure and interchangeability in the event of a defect, however, there is a mumbling one Stability especially in the peripheral areas of the Reclining furniture, generally its deformity and the one-sidedness of the air cushion.
  • EP 0 453 363 B1 discloses a mattress body that is a Air cushions or around conventional bed springs curved trachea only in the central zone of the Provides mattress body while the head and Foot zones are built conventionally. With this arrangement of the Air chambers can be more heavily loaded Buttocks area needs and variable set higher pressure than in the head and Foot zones; this also makes the one described Problem of shifting the internal pressure disarmed or even in the case of air pipes eliminated.
  • the disadvantage of this is that Construction that is both complicated and bulky and the individual zones are not connects compactly, but only strung together. The individual zones can do not act as a uniform spring system.
  • US 5 509 154 discloses an automatic, by the user via remote control operable control system with which in two Air cushions arranged alongside each other different air pressures applied and constant can be held.
  • the disadvantage here is that Irregularity of the system with an air pump that is not integrated in the bed frame.
  • the Control is limited to the Regulation of a maximum of two air cushions neither with the bed frame nor with one upper and lower padding compactly connected are.
  • EP 0 620 716 B1 describes one Mattress with one or more air chambers and with integrated, responsive to stress Air system for automatic refilling Air diffusion.
  • the disadvantage is that the Pressure of each air chamber does not have a single one Remote control device can be controlled but a separate one for each air chamber, by hand adjustable pressure regulating valve required.
  • padding and air cushions are not compactly connected. The stability of the The body of the mattress is therefore largely based on a solid, enveloping coating of mostly natural material like that used for air beds is known.
  • the object of the invention is that overcome disadvantages described and a To create a mattress of the type mentioned so high lying comfort that it can be used simplest bases can be combined and thus the manufacture of an inexpensive Lounger furniture enables.
  • the task accomplishes Mattress body with the features of the claim 1.
  • Other features according to the invention are based the dependent claims, and their Advantages are in the description below explained.
  • Fig. 1 The longitudinal section of a mattress body with the forces acting on it in a schematic Presentation.
  • Fig. 2 The perspective view of a Lounge furniture with partially cut open Mattress body.
  • FIG. 2a A detailed representation of Fig. 2.
  • Fig. 3 The schematic representation of a Air cushion with different air chambers.
  • Fig. 4 The schematic representation of a Mattress body (molded foam).
  • Fig. 5 The schematic representation of a Mattress body with a double bed additional precautions for the variable Adjustment of the inner spring (air chambers, Control).
  • Fig. 6 The block diagram of the controller for the variable adjustment of the inner spring.
  • Fig. 6a The block diagram of a variant of Control for the variable setting of the inner spring.
  • Fig. 1 shows the acting forces (F) when loaded by use.
  • F acting forces
  • the force acting on the head and feet, but also in the cross section is the smallest, with the shoulder section roughly in between.
  • the strength can also be great in the cross zone. It should also be taken into account that these zones do not form clear boundaries, but shift due to the movement of a user in the plane or overlap in the boundary zones.
  • the mattress body according to the invention. 2 takes into account the problem of forces acting differently at different points to a previously unknown extent.
  • the mattress body 2 consists of the centrally arranged air cushion 6 and the so-called elastic molded body 5.
  • the air cushion 6 acts as an inner spring (f1, f4).
  • This spring system creates a spring effect that loosens dynamically in the different zones of the mattress body and maintains the lying profile of a user who is also moving.
  • the high spring power of the mattress body 2 according to the invention enables it to be used without a resilient sub-mattress, as is conventionally used in connection with reclining furniture for the living area in which a high level of lying comfort is important.
  • 2 shows, for example, a simple, non-resilient base frame 3 can be used.
  • Such reclining furniture 1 has significant cost advantages in manufacture compared to conventional bed systems with resilient bottom mattresses.
  • the mattress body 2 is also suitable for use in motor beds, which are often equipped with hard but movable bases, particularly in the hospital area.
  • the so-called elastic molded body 5, as FIG. 2 further shows, consists of two longitudinal beams 17 and two transverse beams 18 which form the frame, which in turn is closed off from above and below by the upper cover mat 19 and the lower cover mat 20.
  • Both cover mats 19, 20 on the one hand each have a row of finger-thick air exchange channels 21 arranged one behind the other and extending transversely to the mattress body, and on the other hand, offset and underneath or above, a row of finger-thick ventilation channels 22 arranged one behind the other and running transversely to the mattress body Longitudinal beams 17, but not the transverse beams 18, in turn have an upper and lower row of ventilation ducts 22 ', their position below the ventilation ducts 22 of the upper cover mat 19 or above the ventilation ducts 22 of the lower cover mat 20 are arranged.
  • the nonwovens have a sound-insulating effect.
  • the air cushion 6 consists of an upper airtight film 25 and a lower airtight film 26, which are welded to one another in such a way that they form a web 7 around the side of the air cushion 6 at half the side height. This web is inserted and glued all around in the corresponding slots 4 of the longitudinal beams 17 and cross beams 18. According to the invention, the air cushion 6 and the elastic molded body 5 are connected to one another in a force-locking manner. The position of the web 7 at half the side height corresponds to commercially available air cushions 6 which are laterally cambered towards the outside.
  • the spring system according to the invention thus absorbs the load pressures acting on the mattress body 2 not only by a vertical spring (f1, f2) but also by a horizontal spring (f4, f5).
  • the air cushion 6 has in its interior longitudinal support walls 29 and transverse support walls 30, which give the air cushion 6 a rib-shaped surface.
  • Fig. 3 shows an example with 2 longitudinal support walls 29 and a plurality of transverse support walls 30 distributed over the entire length of the mattress body. Another arrangement of the support walls, such as that there are more longitudinal support walls 29 and fewer transverse support walls 30, is readily with the technical teaching compatible with the present invention.
  • the ventilation ducts 22 of the upper cover mat 19 and lower cover mat 20 are - as shown in FIGS. 2 and 2a - positioned along the long side of the elastic molded body 5 such that they are above or below those through the rib-shaped surface of the air cushion 6 formed depressions 12 come to rest.
  • the ventilation channels 22 ′ of the longitudinal beams 17 are positioned such that they open into the depressions 12 formed by the rib-shaped surface of the air cushion 6.
  • the elastic molded body 5 ′ can form a non-positive connection with the web 7 and a positive connection with the air cushion 6 as a whole.
  • the breathable film 13 has the function of enabling the air cushion 6 to be positively enclosed by the elastic molded body 5 'and at the same time to prevent a non-positive connection being created with the exception of the web 7.
  • the purpose of this arrangement is that the elastic molded body 5 ′ adapt optimally to the air cushion 6 with a variable air chamber volume and that a surface tension that hinders the spring power cannot arise.
  • the outer spring can be Compacting or padding the elastic Shaped body 5 at the desired locations arrange differently.
  • the molded body can be made from conventional PUR foam or latex his. For example, it is possible to Shoulders with compressed foam manufacture, while the rest of the cover mats 19.20 made with normal compressed foam becomes. For body weight users provided mattress bodies 2 it is also conceivable, the entire central zone of the cover mats 19.20 and the shoulders with compressed Foam.
  • the outer spring (f2, f5) is determined by fixed measures
  • the inner spring (f1, f2) can be variably adjusted by changing the internal pressure. This is described below with reference to the example shown in FIG. 5 for a double bed with two air cushions 6, each of which has two independent, non-communicating air chambers 27, 28. There are a total of four independent, non-communicating air chambers.
  • the air cushions 6 are non-positively connected to an elastic molded body 5 which has longitudinal beams 17, cross beams 18, an upper cover mat 19 and a lower cover mat 20; instead, a non-positive and positive connection with a molded one-piece molded body 5 'is also possible.
  • the air cushions 6 each consist of a chamber 27, which corresponds to the head and foot zone of a mattress body 2, and from a chamber 28, which corresponds to the central zone of a mattress body 2.
  • Chamber 28 has an airtight partition 28 'to define it from chamber 27.
  • a connecting channel 27 ' connects the two zones of the chamber 27.
  • a commercially available, low-noise 12 or a 24-volt compressor with a relatively low delivery capacity fulfills its purpose for this purpose, since the mattress bodies, without wishing to be limited to this embodiment, are already brought to the market in an inflated state and, for example, in the event of defects, they are repaired or replaced by the factory.
  • the inflator 32 is connected to the air chambers 27, 28 of both air cushions 6 via the valve control block 33 and separate air lines 34 leading to and from each of the four air chambers.
