Definitions

  • the invention is directed to a mattress in the preamble of
  • the type of application of the invention is particularly aimed at mattresses such as those used for beds Find.
  • hollow body spring elements made of plastic.
  • This Hollow body spring elements have an in at least some areas Fold up the wall. In the walls of the spring elements there are small openings through which the air is limited can flow through.
  • the air in the hollow body spring element supports the spring action of the spring element. The air escapes slowly, as desired, during a load the hollow body spring element.
  • this has the disadvantage with the fact that the air is just as slowly back into the Hollow body spring element can flow back when the spring element is relieved and the hollow body spring element itself in his Defaults.
  • the hollow body spring elements described therefore have a very poor provision behavior on.
  • the object of the present invention is now to produce a mattress which avoids the disadvantages mentioned and which offers good lying comfort. This is achieved according to the invention by the measures mentioned in the characterizing part of claim 1, which have the following special meaning.
  • the peculiarity of the present invention is that Openings are provided in the hollow body spring elements that with a valve part interact through which they in Air outlet direction are at least partially closable. Thereby it is achieved that the air when the hollow body spring element is relieved again quickly through the air inlet openings in the Interior of the resetting hollow body spring element can flow back while the air is loaded with the hollow body spring element only flow slowly through the air outlet openings can.
  • the mattress according to the invention thereby receives excellent Resilience properties, and at the same time exhibits excellent air-assisted spring action.
  • valve part inside Hollow body spring element is arranged.
  • a valve lip be placed directly behind an opening.
  • valve part in an assembly then attached as a whole to an opening and with this cooperates.
  • both the slow Air flows out when the spring element is loaded, as how also the rapid inflow of air again when that Resets the spring element when the load is released.
  • plastic as a material for the Hollow body spring elements according to claim 9
  • long mattress life is achieved because the difference in material hardness between the top and the lower support and the spring elements is minimized and thus the Abrasion on the supports by the spring elements negligible becomes.
  • Another advantage of the mattress according to the invention is that low technical expenditure for the production of a such a mattress is necessary.
  • plastics for this application have become polyethylene 30 / 20D, thermoplastic Vulcanizate (TPV) and polyester elastomer (TPE-E) have been proven.
  • the mattress has zones of different hardness.
  • hollow bodies of spring elements of different spring hardness are advantageously arranged in the individual zones.
  • the different spring hardness of the hollow body spring elements can be influenced on the one hand by the selection of the material and its thickness, and on the other hand by a variation in the size of the air outlet opening. For example, by using low-elastic material, a higher spring hardness can be preset than when using high-elastic material.
  • a means is provided that the hollow body spring elements in their position and position to each other and to the conditions stabilized.
  • Such a thing Means can e.g. be a plate or a grid, which the Holds hollow body spring elements at the same distance from each other.
  • the hollow body spring elements have pins at both ends by means of which they are connected the requirements can be combined. It is thereby achieved that the upper and lower ends of the hollow body spring elements only perform small movements relative to the cushions, so that too this measure minimizes wear on the supports.
  • the invention is concerned around a mattress (10).
  • this mattress (10) are between one upper and a lower support (11, 12) hollow body spring elements (13) arranged, but the pads (11, 12) are also omitted could.
  • the mattress is usually of at least one Layer of fabric wrapped, but not shown in the drawing is.
  • the pads (11, 12) can still be made of e.g. Horsehair or new wool are covered.
  • the hollow body spring elements (13) have a cylindrical shape in this embodiment, which is not a requirement, and are made of plastic.
  • the walls (20) of the hollow body spring elements (13) are partially (Fig. 2) or completely (Fig. 1 and 3) designed as bellows (17), the planes spanned by the individual folds in this embodiment perpendicular to the longitudinal axis the hollow body spring elements (13). If a person lies down on the mattress, the hollow body spring elements (13) are compressed depending on the weight on them, the material counteracting this compression.
  • the wall (20) of the hollow body spring elements (13), which is at least partially designed as a bellows (17), supports the directional movement of the hollow body spring elements (13) and at the same time increases the stability of the hollow body spring elements (13).
  • openings (16) are provided in the hollow body spring elements on the head side.
  • these openings (16) are let in laterally in a central region into the wall (20) of the hollow body spring elements (13).
  • the openings (16) are divided into an opening cross section (24) and a further opening cross section (25), wherein these opening cross sections can be separated from one another (see FIGS. 2 and 3) or in one and the same opening (16) (see Fig. 5) may lie.
  • the size of the opening cross section (25) determines not only the selected material and its thickness, but also the damping property of the hollow body spring elements (13). Not shown in the drawings is the fact that by varying the size of the opening cross section (25) within different zones of the mattress, zones of different hardness can easily be produced in the mattress. Of course, the material and / or the wall thickness of the hollow body spring elements can be chosen differently depending on the zone in order to produce different hardness zones.
  • the inflow and outflow of air cause a whistling noise.
  • This is counteracted in the simplest manner by providing a sound-absorbing or sound-absorbing means (23) on the outside of the opening cross section (25), which suppresses the unpleasant noises.
  • the position of such a means (23) is shown in FIGS. 2-4, although other arrangements are also possible.
  • the means (23) can be attached to the hollow body spring element (13), for example by gluing. Not shown in the drawings, but in the sense of the present invention it is if the means (23) is identical to the supports (11, 12) or an alignment means (18), namely if they are made of a corresponding sound-absorbing / sound-absorbing material are made and they cover the openings (16).
  • the individual hollow body spring elements (13) are in the Embodiment in Fig. 1 still by a plate-like Alignment means (18) stabilized in position.
  • the single ones Hollow body spring elements (13) pass through the bushing (19) of the alignment means (18).
  • the bushings (19) are there according to the distances between the individual spring elements in Alignment means (18) arranged. It still remains at this point mention that the alignment means (18) e.g. even from individual ones Webs can exist, each between two individual hollow body spring elements (13) can be fastened, and these together connect.
  • the hollow body spring elements (13) in completely Foam can be edged, or they could be so tight be arranged so that they support each other.
  • valve lip (26) there are elements in the hollow body spring elements (13) (26) provided, which in the illustrated embodiments as Valve lip (26) are designed and with the Interact with cross sections (24).
  • the valve lip (26) is in this embodiment in the interior of the hollow body spring element (13) arranged.
  • the opening cross section (24) allows the air to be sucked in quickly in the event that Hollow body spring element (13) is relieved, and thus improved significantly the resetting properties of the mattress.
  • a Load i.e. when pressurizing the hollow body spring element (13), prevents the valve lip (26) from escaping the air from the interior (21) through the opening cross section (24).
  • Opening cross-section (25) also unidirectional, see above that only an outflow of air is possible through it.
  • both opening cross sections (24, 25) are arranged together in one opening (16).
  • the valve lip (26) has a cutout (27) which saves the opening cross section (25) when the valve lip (26) is pressed against the opening (16).
  • the valve lip (26) can have a corrugated edge profile, as a result of which the opening cross section (25) is also shifted to the periphery of the opening (16).
  • valve-like combination (16, 26) shown in FIG. 2 can generated directly during production with the plastic injection molding process first, the actual hollow body spring element (13) is injected and then the valve lip (26) in the Hollow body spring element (13) is injected.
  • the valve lip (26) can also be provided in an attachment, which is retrofitted.
  • the hollow body spring elements have at their upper and lower ends (13) each have a pin (15/23), which in a Receptacle (14) of the upper / lower support (11, 12) can be inserted, and thereby the hollow body spring element (13) in a certain Position fixed on the supports (11, 12).
  • the element (26) can also be designed as a valve body, for example as a spherical or conical body.
