Abstract
A simply constructed, inexpensive underlay (10) for which the underspringing arrangement (12) is formed in the simplest case by a plastic sheet (15), which is selectively reinforced by supplementary crosslinking of the plastic of the plastic sheet (15). This crosslinking provides the plastic sheet (15) with supplementarily consolidated, more stable regions (20), which support the mattress (11). If required, the plastic sheet (15) having supplementarily consolidated regions (20) may be assigned spring strips (14). It is also conceivable to integrate the underspringing arrangement (12) in the mattress (11). The underspringing arrangement (12) formed according to the invention can be easily produced, thereby creating a low-cost underlay (10) with good resilient properties.
Description
- 1. Technical Field
- The invention relates to an underlay for the human body with at least one mattress of foam plastic or with at least one mattress of foam plastic and an underspringing arrangement. Furthermore, the invention relates to a method for producing an underlay for the human body, the underlay being formed by at least one mattress of foam plastic and an underspringing arrangement.
- 2. Prior Art
- Underlays of the type referred to here are used in the case of beds and furniture for sitting and lying on. The underlays are intended to offer sleeping, lying and sitting comfort appropriate for the requirements.
- In the simplest case, such an underlay comprises a mattress, which rests directly on a framework, for example a bed. Such underlays have minimal sleeping, lying and sitting comfort. High-grade underlays have in addition to the mattress an underspringing arrangement, which offers a resiliently compliant, elastic support for the mattress. Known underspringing arrangements of this type require a complex construction, making the underlays expensive.
- The invention is based on the object of providing a simple, inexpensive underlay, which nevertheless offers a high degree of sleeping, lying and/or sitting comfort for the human body. Furthermore, the invention relates to a method for the simple and inexpensive production of an underlay for the human body.
- An underlay serving to achieve this object comprises at least one mattress of foam plastic, characterized in that supplementarily consolidated regions are assigned to the mattress. Accordingly, the mattress is assigned supplementarily consolidated regions of its foam plastic. These supplementarily consolidated regions harden or stabilize the material of the mattress at selected locations. As a result, the underspringing arrangement can be virtually integrated in the mattress.
- Another underspringing arrangement for achieving the stated object comprises at least one mattress of foam plastic and an underspringing arrangement, characterized in that supplementarily consolidated regions are assigned to the underspringing arrangement. Accordingly, the underspringing of the mattress is assigned supplementarily consolidated regions. Such a separate underspringing arrangement is simple to manufacture.
- The supplementarily consolidated, in particular supplementarily crosslinked, regions form selectively hardened parts of the mattress or of a layer of plastic supporting the latter, which obviates the need for a complex underspringing arrangement. The hardened regions can be easily formed by supplementary consolidation from the material of the mattress or an additional layer of plastic. As a result, an underlay which is equivalent to a mattress lying on a complex underspringing arrangement with regard to the sleeping, lying and sitting comfort is obtained in an inexpensive way.
- If the regions selectively hardened by supplementary crosslinking are formed from a separate layer of plastic, this may be a foam plastic sheet or else a sheet of unfoamed plastic, in particular an elastomer sheet. An underspringing arrangement for the mattress can be formed from this very easily by simple supplementary crosslinking of the plastic, whereby the selectively hardened regions for supporting the mattress are created. A curable polymer also comes into consideration in particular as the plastic for the plastic foam.
- In the case of a preferred form of the invention, the underlay has supporting elements. The supporting elements are assigned to the mattress, to be precise in such a way that they are located in the mattress or under the mattress. The supporting elements form an additional support for the mattress.
- According to a further refinement of the invention, the supporting elements are assigned to the selectively hardened or supplementarily consolidated regions of the mattress or its integrated underspringing arrangement or a separate underspringing arrangement. In this case, the selectively hardened, in particular supplementarily hardened or supplementarily crosslinked, regions serve as supporting locations or load distributors, in that they introduce the load of the person resting on the mattress via the foam plastic of the mattress into the supplementarily consolidated regions and from there into the supporting elements. In this way, the supplementarily hardened regions form an underspringing arrangement together with the supporting elements.
- According to a preferred refinement of the invention, the underspringing arrangement formed by the supplementarily hardened or supplementarily consolidated regions and the supporting elements, but also, if appropriate, just by the supplementarily consolidated regions, is an integral part of the mattress. In particular when no supporting elements are provided, the underlay according to the invention substantially comprises only the mattress with its supplementarily consolidated regions. It is also conceivable to form the underspringing arrangement separately. Then the elastic underspringing arrangement forms the underlay together with the mattress, the underspringing arrangement supporting the mattress.
- According to a preferred refinement of the invention, the selectively hardened regions of the mattress or of the underspringing arrangement are connected to the supporting elements. This connection preferably takes place with positive engagement, but may also be additionally or alternatively created by adhesive bonding, welding or the like. The connection of the supporting elements to the supplementarily consolidated or supplementarily crosslinked regions leads to the supporting elements and the supplementarily consolidated or reinforced regions forming a functional unit which is effective altogether as an underspringing arrangement, to be precise independently of whether this underspringing arrangement is arranged separately under the mattress or is an integral part of the same.
- The selectively hardened, in particular supplementarily consolidated, regions are formed as punctiform 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 in a strand-like manner. The strand-like structures preferably extend continuously over the entire length or width of the underlay, in particular of the mattress. The strand-like structures then form a continuous reinforcement of the mattress or of the underspringing arrangement lying under it. On account of the strand-like structures, it may be possible to dispense with additional supporting elements. In the latter case, the underlay in its simplest form merely comprises the mattress, in that the selectively supplementarily hardened regions, in particular the strand-shaped structures, are an integral part of the same. Such an underlay can be produced particularly easily and inexpensively.
- The supporting elements are preferably formed as strips, in particular spring strips, extending continuously over the entire width or length of the mattress. As a result, good stabilization of the mattress is brought about. If all or some of the supporting elements are formed as spring strips, they form part of a resilient supporting structure, in particular an underspringing arrangement, of the mattress, to be precise even when the underspringing arrangement is integrated in the mattress with the strips and/or spring strips and also the supplementarily consolidated regions.
- If the underspringing arrangement is formed as an integral part of the mattress, the supplementarily hardened regions and/or the supporting elements, to be precise strips or spring strips, are arranged in the region of the underside of the mattress. As a result, the mattress is supported in a way similar to how it is supported by a separate underspringing arrangement. In this case, the supplementarily hardened regions expediently extend from the underside of the mattress. The supporting elements, that is to say the strips and/or spring strips, are also inserted or pushed from the side into corresponding recesses in the underside of the mattress, which extend through the supplementarily hardened punctiform or elongated structures.
- A method for achieving the object mentioned at the beginning has the measures of the underlay being formed by at least one mattress of foam plastic and an underspringing arrangement, characterized in that the underspringing arrangement is formed by at least one layer of plastic or foam plastic, and regions of the layer of plastic or foam plastic are supplementarily consolidated by subsequent selected crosslinking. Accordingly, the underspringing arrangement integrated in the mattress or separate underspringing arrangement is formed from a layer of plastic or foam plastic, regions of the at least one layer of plastic or foam plastic being supplementarily consolidated by subsequent crosslinking. This allows the underspringing arrangement to be formed in the simplest way by the supplementary crosslinking and accompanying curing of selected regions of the layer of plastic or foam plastic. As a result of the invention, structural changes or additional parts are not required to form the underspringing arrangement.
- A particularly simple underlay is obtained if the underspringing arrangement is formed from a part, in particular a lower part, of the foam material of the mattress. The underspringing arrangement then does not even require an additional plastic material, because the foam plastic that is required in any case to form the mattress is used to form the supplementarily consolidated regions.
- The subsequent crosslinking of the foam plastic of the mattress or of an additional layer of plastic to form a separate underspringing arrangement takes place thermally. For this purpose, electron beams, infrared beams or ultraviolet light may be used. These allow a targeted effect to be produced on the plastic, in particular foam plastic, in certain regions, so that punctiform or strand-like supplementarily consolidated structures are selectively created at the intended locations, but supplementary consolidation is not carried out on the entire mattress or the entire additional layer of plastic, as a result of which the supplementarily consolidated regions do not appreciably influence, in particular do not significantly reduce, the elasticity of the mattress or of the additional layer of plastic. These structures are either sufficient on their own to form the underspringing arrangement or they are supported on additional supporting elements such as elongated strips, in particular spring strips, the supplementarily consolidated regions or structures having the effect that the force exerted on the mattress by the person lying on it is introduced into the supporting elements over a large surface area.
- Preferred exemplary embodiments of the underspringing arrangement according to the invention and of the method for producing the same are explained in more detail below on the basis of the drawing, in which:
-
FIG. 1 shows a partial longitudinal section through an underlay according to a first exemplary embodiment of the invention. -
FIG. 2 shows a partial longitudinal section through an underlay according to a second exemplary embodiment of the invention. -
FIG. 3 shows a perspective partial view of the underlay ofFIG. 2 . -
FIG. 4 shows a perspective partial view analogous toFIG. 3 of an underlay according to a third exemplary embodiment of the invention. - The figures show parts of various underlays for furniture for sleeping, lying or sitting on. The respective underlay is supported by a frame of the furniture, for example a bed frame. The underlay receives a person, who lies on it in the case of a bed or lounger or sits on it in the case of a chair or armchair. To increase the sleeping, lying or sitting comfort, the underlay is intrinsically elastic and/or elastically deformable, in that it at least partially bends.
-
FIG. 1 shows a first exemplary embodiment of anunderlay 10, which is formed by a preferablyrectangular mattress 11 and a separate, elasticallycompliant underspringing arrangement 12. Themattress 11 rests with itsunderside 13 on theunderspringing arrangement 12. Themattress 11 shown here is formed in one piece from foam plastic. Themattress 11 may, however, also be made up of more than one part, to be precise of mattress parts lying one behind the other in the longitudinal direction and/or of a number of layers or part-mattresses lying one on top of the other. If themattress 11 is formed by a number of layers lying one on top of the other, they may be connected to one another by positive engagement and/or adhesive bonding or be arranged in a common covering (not shown). Themattress 11 of the exemplary embodiment shown can consequently be formed conventionally in any desired customary way. - In the case of the exemplary embodiment shown, the
separate underspringing arrangement 12 of theunderlay 10 is formed in a special way according to the invention. Theunderspringing arrangement 12 has a number of supporting elements, which are formed here as strips, to be precise in particular as spring strips 14. A number of identical spring strips 14 are arranged such that they run parallel to one another with a spacing. The spring strips 14 extend continuously along under themattress 11 in a transversely directed manner. Furthermore, theunderspringing arrangement 12 has a layer of plastic, which is preferably formed as aplastic sheet 15. Theplastic sheet 15 may be formed from foam plastic or else from compact plastic, in particular an elastomer. In the exemplary embodiment shown here, theplastic sheet 15 has a contour undulating in the longitudinal direction of theunderlay 10, thereby creatingsuccessive curvatures 16 and 17, which are continuously profiled along the spring strips 14, so that they have approximately the same cross section along the spring strips 14. The plastic sheet may, however, also be curved in the transverse direction of themattress 11. One type of curvature 16 extends over eachspring strip 14, while the other type ofcurvature 17 is located between two adjacent spring strips 14. Theupper vertices 18 of thecurvatures 16 and 17 lie against theunderside 13 of themattress 11. Betweensuccessive curvatures 16 and 17, theplastic sheet 15 has double-layer, approximately U-like connectingregions 19, which lie against opposite sides of the spring strips 14. - According to the invention, the
plastic sheet 15 is partly supplementarily crosslinked and thereby cured. As a result, theplastic sheet 15 has supplementarily consolidated regions 20. These are illustrated inFIG. 1 by a crosshatching. It is evident from this that the supplementarily consolidated regions 20 extend substantially over the curvatures 16 assigned to the spring strips 14 and the connectingregions 19 adjoining them on both sides. The supplementarily consolidated regions 20 are specifically assigned only to the spring strips. It is also conceivable for the middle part of the curvatures 16, which rests on the spring strips 14, not to be formed as a supplementarily consolidated region 20. In the supplementarily consolidated regions 20, theplastic sheet 15 has a greater strength and also rigidity. This produces a positively engaging solid connection of theplastic sheet 15 in the regions of the curvature 16 to the spring strips 14. The supplementarily consolidated regions 20 also contribute to the stabilization of thecurvatures 17 of theplastic sheet 15 between the spring strips 14, which are not supplementarily consolidated. This stabilization has the effect that the force exerted on themattress 11 by the person lying or sitting on it is introduced more uniformly into theunderspringing arrangement 12. Outside the supplementarily consolidated regions 20, theplastic sheet 15 has its original, unreduced strength and elasticity. These properties are changed in the supplementarily consolidated regions 20 by the supplementary crosslinking. In particular, theplastic sheet 15 or the layer of plastic in the supplementarily consolidated regions has a greater strength and rigidity. - In the production of the
underspringing arrangement 12, the following procedure is adopted: the foamed or unfoamedplastic sheet 15, made preferably of a curable polymer, is firstly placed in a wave-like manner over the spring strips 14 and subsequently thermally consolidated in certain regions, that is in a targeted manner, in that the supplementarily consolidated regions 20 are specifically exposed to energy beams. This causes a partial, that is local, supplementary crosslinking of the plastic, whereby the latter cures in the irradiated, supplementarily consolidated regions 20. The selective thermal treatment of theplastic sheet 15 may take place by electron beams, infrared beams or else ultraviolet light. For this purpose, the light or the beams is/are selectively directed only onto the regions 20 that are to be supplementarily consolidated or supplementarily crosslinked. The spring strips 14 are preferably formed from a plastic which is not cured or supplementarily crosslinked under the influence of the thermal treatment of theplastic sheet 15, so that it remains excluded from the thermal treatment or supplementary crosslinking of the regions 20. Those regions of theplastic sheet 15 which are not to be supplementarily consolidated are not subjected to supplementary thermal treatment. These are, in particular, thecurvatures 17, in the region of which theplastic sheet 15 substantially retains its original strength and elasticity. This strength is less than in the supplementarily consolidated regions 20. The elasticity of theplastic sheet 15 outside the supplementarily consolidated regions 20 is also greater than in the supplementarily consolidated regions 20. The supplementary consolidation by supplementary crosslinking may be performed to such a degree that, in the supplementarily consolidated regions 20, theplastic sheet 15 then only has a very small residual elasticity or substantially no elasticity at all. - Alternatively, it is conceivable for the
plastic film 15 to be thermally supplementarily crosslinked and cured before it is placed onto thespring strip 14, to be precise only in those regions of theplastic sheet 15 which correspond to the supplementarily consolidated regions 20 above the spring strips 14 running transversely in relation to the longitudinal direction of theunderlay 10. -
FIG. 2 shows anunderlay 21 according to a second exemplary embodiment of the invention. Thisunderlay 21 substantially comprises only themattress 22. Aseparate underspringing arrangement 12, as in the case of the exemplary embodiment ofFIG. 1 , is not present in the case of theunderlay 21. Rather, this underspringing arrangement is integrated in themattress 22, to be precise in an underside region of the same. - In
FIG. 2 , themattress 22 is formed in one piece or one layer. It may, however, also be formed in more than one piece or more than one layer, as described further above in connection with the exemplary embodiment ofFIG. 1 . - In addition to the
mattress 22, theunderlay 21 has supporting elements. The supporting elements are formed by strips, these being spring strips 23 in the exemplary embodiment shown. The spring strips 23, running parallel with a spacing, are assigned to theunderside 24 of themattress 22. In the present case, the spring strips 23 lie in themattress 22, to be precise in such a way that they are surrounded by themattress 22 apart from a partial region of their underside. The spring strips 23 may, however, also be completely embedded in themattress 22, so that they are entirely surrounded by the foam plastic of themattress 22. In this way, the spring strips 23 extending transversely in relation to the longitudinal direction of themattress 22, continuously over the entire width of the same, are for the most part embedded in themattress 22, to be precise in such a way that they lie within the outlines of themattress 22. However, it is also conceivable for the spring strips 23 to lie only partially within themattress 22 or to be located completely under theunderside 24 of themattress 22. - The
mattress 22 is formed completely from foam plastic. Partial regions of the foam plastic are made harder by thermal supplementary crosslinking than the original remaining part of the foam plastic of themattress 22. In the exemplary embodiment shown, the supplementarilyconsolidated regions 25 created by thermal supplementary consolidation are assigned to the spring strips 23. For this purpose, the supplementarilyconsolidated regions 25 extend over those parts of themattress 22 which surround therespective spring strip 23 in cross section (FIG. 2 ). The size of the respectively supplementarilyconsolidated region 25 corresponds to the requirements. It can be varied as need be. The supplementarilyconsolidated regions 25 assigned to eachspring strip 23 have the effect that the foam plastic of themattress 22 is hardened in certain regions, that is only partly, whereby reliable retention, if appropriate with positive engagement, of the spring strips 23 in themattress 22 is ensured. Furthermore, the supplementarilyconsolidated regions 25 have the effect that the force exerted on themattress 22 is introduced into the spring strips 23 over a large surface area, whereby stable support of themattress 22 on the spring strips 23 comes about even without aseparate underspringing arrangement 12. In the case of theunderlay 21, this underspringing arrangement is virtually integrated in themattress 22 and is consequently part of the same. - The supplementarily
consolidated regions 25 are three-dimensionally formed. The supplementarilyconsolidated regions 25 shown inFIG. 3 are formed in a punctiform manner, to be precise as mushroom- or dome-like structures. A number of theseregions 25 supplementarily consolidated in a punctiform manner follow one another, either lying directly one against the other or spaced apart from one another, along thespring strip 23, the spacings between the punctiform structures for forming the supplementarilyconsolidated regions 25 being variable in a way corresponding to the requirements. -
FIG. 4 shows supplementarilyconsolidated regions 26 according to an alternative exemplary embodiment of the invention. Here, eachspring strip 23 is assigned a continuous, elongated supplementarilyconsolidated region 26. Such a supplementarilyconsolidated region 26 forms a strand-like structure, which extends over the entire width of themattress 22 or length of thespring strip 23, to be precise uninterruptedly. The supplementarilyconsolidated regions 26 thus form a partial tube, which surrounds the cross section of therespective spring strip 23 to the extent that the latter is enclosed by themattress 22. - The production of the underlay according to FIGS. 2 to 4 takes place by a mat corresponding to the shape of the
mattress 22 being cut out from a block of foam plastic. Transversely directed, continuous grooves, which are large enough to receive the spring strips 23, if provided, are then cut into theunderside 24 of the foam plastic mat at locations where the spring strips 23 are later to be accommodated, to form themattress 22. The spring strips 23 are then placed into these grooves and supplementary consolidation of the originally relatively soft foam plastic is subsequently performed selectively where the supplementarilyconsolidated regions mattress 22 is partially and selectively cured, in that it is thermally supplementarily crosslinked, to be precise in the way described in detail in connection with the exemplary embodiment ofFIG. 1 , that is by electron beams, infrared beams and/or UV light. The spring strips 23 may, however, also be pressed into theunderside 24 of themattress 22, that is the foam plastic mat serving to form the same, obviating the need for grooves to be cut in. - Alternatively, it is conceivable to perform the supplementary crosslinking of the plastic foam of the
mattress 22 before the placement of the spring strips 23 into the grooves cut into theunderside 24 of themattress 22, and thereby form the punctiform supplementarilyconsolidated regions 25 or the strip-shaped supplementarilyconsolidated regions 26. Subsequently, the spring strips 23 are pushed or pressed or clamped into the downwardly open grooves remaining in theregions mattress 22, in particular the supplementarilyconsolidated regions - The invention is also suitable for underlays (not shown) which do not have supporting elements, so that the spring strips 14 or 23 shown in FIGS. 1 to 4 are entirely absent or else only partly absent. The separate underspringing arrangement, or underspringing arrangement integrated in the mattress, is then formed just by the supplementarily
consolidated regions plastic sheet 15 with supplementarily consolidated regions 20. In this case, the supplementarily consolidated regions 20 of theplastic sheet 15 need not run continuously in a strand-like manner to form the underspringing arrangement; they may also be present in a punctiform manner (as in the case of the exemplary embodiment ofFIG. 3 ), so that the supplementarily consolidated regions 20 are formed by mushroom- or dome-like local structures. As a departure from the exemplary embodiment shown, the structures may have any desired other shape. -
