Definitions

  • the invention relates to a pad for the human body according to the preamble of claim 1. Furthermore, the invention relates to a method for producing a pad for the human body according to the preamble of claim 11.
  • Documents of the type mentioned here are used in beds, sitting and lying furniture use.
  • the documents should offer sleeping, lying and sitting comfort that meets the requirements.
  • Such a base is in the simplest case of a mattress, which rests directly on a frame, such as a bed.
  • a frame such as a bed.
  • Such documents have a minimum sleeping, lying and sitting comfort.
  • High-quality documents have in addition to the mattress on a spring base, which provides a resilient, resilient support for the mattress.
  • Known lower suspension of this type require a complex structure, which makes the documents more expensive.
  • the invention has for its object to provide a simple, inexpensive pad, which nevertheless offers a high sleeping, lying and sitting comfort for the human body. Furthermore, the invention relates to a method for simple and inexpensive production of a support for the human body.
  • a serving to solve this problem documents has the features of claim 1. Accordingly, either the mattress has post-consolidated areas of its foam plastic, or the post-consolidated areas of a separate plastic layer are assigned to the mattress. These post-consolidated areas harden or stabilize the material of the mattress at selected locations. As a result, the spring suspension can be practically integrated into the mattress. If the post-consolidated areas are not integrated into the mattress, they form a separate spring base, which is easy to produce.
  • the post-consolidated, in particular post-crosslinked, areas form selectively hardened parts of the mattress or a plastic layer which supports them, thereby eliminating the need for a complicated underslung suspension.
  • the hardened areas can be easily formed by post-consolidation of the material of the mattress or an additional plastic layer.
  • an underlay is created in an inexpensive manner, which is equivalent in terms of sleeping, lying and sitting comfort documents with lying on a lush mattress mattress.
  • the areas selectively hardened by postcrosslinking are formed from a separate plastic layer, this may be a foamed plastic film or else a film made of unfoamed plastic, in particular an elastomer film. From this it is very easy to form a base for the mattress by simply post-crosslinking the plastic, whereby the selectively hardened areas for supporting the mattress arise.
  • a plastic for the plastic foam is in particular a curable polymer into consideration.
  • the pad on supporting organs.
  • the support members are associated with the mattress, in such a way that they are in the mattress or under the mattress.
  • the support members form an additional support of the mattress.
  • the support members are associated with the selectively hardened or post-consolidated areas of the mattress or its integrated lower suspension or a separate lower suspension.
  • the selectively hardened, in particular post-cured or postcrosslinked areas serve as support points or load distributors by introducing the load of the person resting on the mattress over the foam plastic of the mattress into the post-consolidated areas and from there into the supporting elements.
  • the post-hardened areas together with the supporting organs form a spring base.
  • the undershoot formed by the post-hardened or post-consolidated areas and the supporting elements, but optionally also only the underslung formed by the post-consolidated areas is an integral part of the mattress.
  • the underlay according to the invention exists, in particular, when no support members are provided, essentially only from the mattress with its post-consolidated areas. It is also conceivable to form the spring suspension separately. Then forms the elastic base suspension together with the mattress, the base, the base suspension carries the mattress.
  • the selectively hardened areas of the mattress or the lower spring are connected according to a preferred embodiment of the invention with the support members.
  • This connection is preferably positive fit, but can also be produced additionally or alternatively by gluing, welding or the like.
  • the connection of the support members to the post-bonded or post-cured portions results in the support members and the subsequently solidified portions forming a functional unit acting as a whole as a whole, irrespective of whether this support is separate under the mattress arranged or integral part of the same.
  • the selectively hardened, in particular post-solidified regions are formed as punctual and / or elongated or strip-like three-dimensional structures.
  • the punctiform structures may be formed as mushroom or dome-like structures, while the elongated structures are formed strand-like.
  • the strand-like structures preferably extend continuously over the entire length or width of the pad, in particular the mattress.
  • the string-like structures then form a continuous stiffening of the mattress or the lower spring arranged below. Due to the string-like structures may optionally be dispensed with additional support members.
  • the pad in its simplest form consists only of the mattress in that the selectively post-hardened areas, in particular the strand-like structures, are an integral part of the mattress. Such a pad is particularly simple and inexpensive to produce.
  • the support members are preferably designed as over the entire width or length of the mattress continuous strips, in particular slats. As a result, a good stabilization of the mattress is brought about. If all or some support members are designed as spring strips, these form part of a resilient support structure, in particular a spring, the mattress, even if the base is integrated with the strips and / or slats and the post-consolidated areas in the mattress.
  • the spring base is formed as an integral part of the mattress, the post-hardened areas and / or the support members, namely strips or slats, in the region of the underside of the mattress are arranged.
  • the mattress is supported in a similar manner as by a separate spring base.
  • the post-cured areas expediently start from the underside of the mattress.
  • the support members that is, the strips and / or slats, from below into corresponding recesses of the underside of the mattress, which extend through the post-cured punctiform or elongated structures used or inserted from the side.
  • a method for solving the above-mentioned problem comprises the measures of claim 11. Accordingly, the integrated into the mattress or separate spring base is formed from a plastic or foam plastic layer, wherein portions of the at least one plastic or foam plastic layer are post-consolidated by subsequent crosslinking. This makes it possible in the simplest way to form the spring base only by the post-crosslinking and the associated curing of selected areas of the plastic or foam plastic layer. Structural changes or additional parts are not required as a result of the invention to form the suspension.
  • a particularly simple pad results when the base is formed from a part, in particular a lower part of the foam of the mattress. Then, not even an additional plastic material is required for the lower suspension, because the foam plastic, which is required anyway for the formation of the mattress, is used to form the post-consolidated areas.
  • the figures show parts of various documents for sleeping, lying or seating.
  • the respective base is supported by a frame of the furniture, for example a bed frame.
  • the pad takes a person who is lying on it in the case of a bed or a reclining furniture or sitting at the chair or armchair on.
  • the pad is to increase the sleeping, lying or sitting comfort in itself elastically and / or elastically deformable by bending at least partially.
  • Fig. 1 shows a first embodiment of a pad 10, which is formed from a preferably rectangular mattress 11 and a separate, elastically resilient spring base 12.
  • the mattress 11 rests with its underside 13 on the spring base 12.
  • the mattress 11 shown here is formed in one piece from foam plastic.
  • the mattress 11 can also be composed of several parts, and be formed both from longitudinally one behind the other mattress parts and / or several superimposed layers or partial mattresses. If the mattress 11 is formed of several superimposed layers, these can be connected to each other by positive engagement and / or gluing or be arranged in a common, not shown enclosure.
  • the mattress 11 of the embodiment shown can thus be conventional in any conventional manner.
  • the separate lower spring 12 of the base 10 is formed in the illustrated embodiment.
  • the spring base 12 has a plurality of supporting members, which are designed here as strips, in particular as spring strips 14. Several identical spring strips 14 are arranged at a distance parallel to each other. The spring strips 14 extend continuously transversely under the mattress 11 along.
  • the spring base 12 has a plastic layer, which is preferably formed as a plastic film 15.
  • the plastic film 15 may be made of foam plastic or of compact plastic, in particular an elastomer.
  • the plastic film 15 has in the embodiment shown here a corrugated in the longitudinal direction of the pad 10 course, whereby successive bulges 16 and 17 are formed, which are profiled along the spring strips 14 continuously, so that they have along the spring strips 14 about the same cross-section.
  • the plastic film may also be arched in the transverse direction of the mattress 11.
  • One type of buckle 16 extends over each spring bar 14, while the other type of buckle 17 is located between two adjacent spring strips 14.
  • the upper apex 18 of the bulges 16 and 17 are below the bottom 13 of the mattress 11 at.
  • the plastic film 15 has two-ply, approximately U-like connecting regions 19 which rest on opposite sides of the spring strips 14.
  • the plastic film 15 is partially postcrosslinked and thus cured.
  • the plastic film 15 has post-solidified regions 20. These are illustrated in FIG. 1 by cross-hatching. It can be seen that the post-strengthened regions 20 extend essentially over the bulges 16 associated with the spring strips 14 and the connecting regions 19 adjacent thereto on both sides.
  • the post-consolidated areas 20 are specifically assigned only to the slats. It is also conceivable not to form the middle part of the bulges 16, which rests on the spring strips 14, as a post-solidified region 20. In the post-consolidated areas 20, the plastic film 15 has a greater strength and also rigidity.
  • the post-consolidated areas 20 also contribute to the stabilization of the non-post-solidified Buckling 17 of the plastic film 15 between the spring strips 14 at. This stabilization leads to a smoothing out of the introduction of the force exerted on the mattress 11 by the person sitting or sitting on it in the spring base 12. Outside the post-solidified areas 20, the plastic film 15 has its original, undiminished strength and elasticity. These properties are changed in the post-solidified areas 20 by the post-crosslinking. Above all, the plastic film 15 or plastic layer in the post-consolidated areas on a greater strength and rigidity.
  • the foamed or unfoamed plastic film 15, preferably made of a curable polymer, is first laid in a wavelike manner over the spring strips 14 and then thermally bonded in certain regions, that is to say in a targeted manner, in that energy is applied to the post-solidified regions 20 in a targeted manner , This results in a partial, namely local, post-crosslinking of the plastic, whereby it hardens in the irradiated, post-solidified regions 20.
  • the selective thermal treatment of the plastic film 15 may be effected by electron beams, infrared rays or ultraviolet light. The light or the rays are selectively directed only to the nachverfestigenden or post-curing areas 20.
  • the spring strips 14 are preferably formed from a plastic which does not cure or postcrosslink under the influence of the thermal treatment of the plastic film 15, so that it remains excluded from the thermal treatment or post-crosslinking of the regions 20.
  • Those areas of the plastic film 15 which are not to be post-consolidated are not thermally treated. These are in particular the bulges 17, in the region of which the plastic film 15 essentially retains its original strength and elasticity. This strength is lower than in the post-bonded areas 20.
  • the elasticity of the plastic film 15 outside the post-consolidated areas 20 is greater than in the post-consolidated areas 20.
  • Post-crosslinking post-consolidation can be operated so far that in the post-bonded areas 20 the plastic film 15 has only a very low residual elasticity or substantially no elasticity at all.
  • Fig. 2 shows a pad 21 according to a second embodiment of the invention.
  • This pad 21 consists essentially only of the mattress 11.
  • a separate base 12 as in the embodiment of FIG. 1 is not present in the pad 21. Rather, this spring base is integrated into the mattress 22, in a lower-side area of the same.
  • the mattress 22 is formed in one piece or single layer. But it can also be designed in several pieces or multi-layer, as has been described in connection with the embodiment of FIG. 1 above.
  • the pad 21 has in addition to the mattress 22 support members.
  • the support members are formed from strips, which in the illustrated embodiment is spring strips 23.
  • the spring strips 23 are spaced parallel to the bottom 24 of the mattress 22 assigned.
  • the spring strips 23 are in the mattress 22, in such a way that they are surrounded by the mattress 22 apart from a portion of its underside.
  • the spring strips 23 may also be completely embedded in the mattress 22, so that they are completely surrounded by the foam plastic of the mattress 22.
  • the transverse to the longitudinal direction of the mattress 22 over the entire width of the same continuous spring strips 23 are largely embedded in the mattress 22, in such a way that they lie within the contour lines of the mattress 22. But it is also conceivable that the spring strips 23 are only partially within the mattress 22 or are completely below the bottom 24 of the mattress 22.
  • the mattress 22 is formed entirely of foam plastic. Subsections of the foam plastic are formed by thermal post-curing harder than the original remaining part of the foam plastic of the mattress 22.
  • the post-solidified areas 25 resulting from thermal post consolidation are assigned to the spring strips 23.
  • the post-consolidated areas 25 extend over those parts of the mattress 22 which surround the respective spring strip 23 in cross-section (FIG. 2).
  • the size of each post-solidified area 25 corresponds to the requirements. It can be varied as needed.
  • the post-solidified areas 25 lead to a large-scale introduction of the force exerted on the mattress 22 force in the spring strips 23, whereby a stable support of the mattress 22 on the spring strips 23 without a separate spring base 12 comes about.
  • This underspring is integrated in the pad 21 quasi in the mattress 22 and thus part of the same.
  • the post-solidified regions 25 are formed in three dimensions.
  • the post-consolidated areas 25 shown in FIG. 3 are punctiform, in the form of mushroom or dome-like structures. Several of these selectively solidified areas 25 follow along the spring bar 23 either directly adjacent to each other or spaced apart, the distances of the punctiform structures for forming the post-solidified areas 25 are varied according to requirements.
  • FIG. 4 shows post-solidified regions 26 according to an alternative embodiment of the invention.
  • each spring strip 23 is associated with a continuous, elongated, post-consolidated region 26.
  • Such a post-consolidated region 26 forms a strand-like structure which extends over the entire width of the mattress 22 or length of the spring strip 23, and that continuously.
  • the post-consolidated areas 26 thus form a partial tube, which surrounds the cross section of the respective spring strip 23, as far as it is enclosed by the mattress 22.
  • the preparation of the pad according to FIGS. 2 to 4 takes place in such a way that a mat of the shape of the mattress 22 is cut out of a foam plastic block.
  • the foam plastic of the mattress 22 is partially and selectively cured by being thermally postcrosslinked, as described in detail in connection with the embodiment of Fig. 1, namely by electron beams, infrared rays and / or UV light.
  • the spring strips 23 can also be pressed into the bottom 24 of the mattress 22, namely the foam plastic mat serving to form the same, whereby the cutting of grooves is unnecessary.
  • the invention is also suitable for documents not shown, which have no support members, so that the spring strips 14 and 23 shown in FIGS. 1 to 4 completely or even partially missing.
  • the separate or integrated into the mattress base is then formed alone from the post-solidified areas 25 and 26 or the plastic film 15 with post-solidified areas 20.
  • the post-consolidated areas 20 of the plastic film 15 need not be strand-like continuous to form the lower suspension; they may also be present at points (as in the exemplary embodiment of FIG. 3), so that the post-solidified regions 20 are formed by mushroom-shaped or dome-like local structures.
  • the structures may have any other shape than the embodiments shown.
