Description

[0001] The invention relates to a substructure device according to the features in the preamble of claim 1.

[0002] Bed bases are known in many forms from practical experience. Essentially, these bases serve to support a bed mattress, with one or more mattresses being spaced apart from a support surface on which the base rests.

[0003] The well-being and sleep experience of a user is essentially determined by the local characteristics of the bed, particularly the distribution of elasticity. Maximum sleeping comfort is achieved through an individual adjustment of the local elasticity of the number of mattresses in conjunction with the local elasticity of the mattress base. Typically, slatted frames, spring cores, and / or similar components form the spring system of the mattress base.

[0004] Box spring beds, for example, offer a particularly high level of sleeping comfort. A defining characteristic of box spring beds is their special base construction, also known as the box or box spring, which incorporates a spring system upon which the multiple mattresses are essentially supported. The sleeping comfort experienced is therefore, among other things, the result of the combined effect of the spring systems in the base and the mattresses.

[0005] Particularly for design reasons, base structures expediently include a frame with numerous side elements, such as several side panels or the like. These side elements typically form a visually appealing edge finish by essentially concealing an internal spring mechanism, especially when combined with a mattress and / or a cover. It is known from practice that a mattress does not usually rest solely on a spring mechanism, but at least partially also on several side elements. Experience shows that even a small area of ​​mattress bearing on several side elements can be sufficient to impair the well-being of the user by disrupting their rest or sleep experience.

[0006] Against this background, the object of the presented invention is to provide a substructure that enables mattress support without impairing the rest or sleep experience of the user. At the same time, the bed should be inexpensive and easy to manufacture.

[0007] Since the problem described is known in particular in connection with box spring beds, the invention is explained here with reference to box spring beds, without limiting the invention to them.

[0008] The problem is solved by a substructure construction according to the features of claim 1 and by a bed according to the features of claim 13. Further advantageous aspects, details and embodiments of the invention will become apparent from the dependent and deferred claims and from the present description.

[0009] A first aspect of the invention relates to a base structure for a bed, in particular for a box spring bed, designed to arrange a number of mattresses at intervals from a standing surface. The base structure according to the invention comprises a frame structure with a plurality of side elements, that is, at least two side elements. Furthermore, the base structure comprises a spring assembly, for example, with a slatted frame, a spring core, and / or the like. A number of the plurality of side elements surround the spring assembly, so that, in a user arrangement, the visibility of the spring assembly is at least partially restricted. Preferably, the plurality of side elements are arranged substantially in a common spring plane with the spring assembly, wherein the spring plane is offset against the direction of gravity and, in particular, arranged parallel to the standing surface. In practice, side elements such as... have proven effective.Sheet materials or similar, which are essentially oriented elongated and / or upright within the frame structure.

[0010] In the context of the presented invention, "number" means a singular or plural feature.

[0011] Furthermore, a first side element of the plurality of side elements, in particular against a weight load acting towards the support plane, i.e. e.g. a weight load caused by a handler, which acts in particular in the direction of the support plane, exhibits a first compression resistance that is smaller than a second compression resistance of a second side element of the plurality of side elements.

[0012] In other words, the invention proposes that, under the influence of the same weight load or force, the first side element, preferably at least partially, is deformed more, i.e., compressed more, than the second side element. This is because the invention is based on the idea of ​​approximating, preferably substantially aligning, the deformation behavior of at least a number of first side elements, in particular their elastic deformation properties, with the deformation properties of the spring assembly, preferably aligning them locally.

[0013] The term compression resistance is used in the context of the invention as a measure to describe the deformation properties of individual materials, components, and / or assemblies of the substructure. In particular, for the testing of components and assemblies, the intended orientation of the components or assemblies, and thus the force acting in a user configuration, must be taken into account. The units of measurement available are those generally known from standard materials testing, e.g., kPa, N / mm², or N / mm². 2 , and / or the like.

[0014] By compressing at least a number of the first page elements of the multitude of page elements more strongly under the weight of a handler than a number of second page elements, and especially more strongly than all second page elements, disturbing sensations in a handler are reduced and the rest or sleep experience is improved.

[0015] The substructure according to the invention can preferably be further developed by the features and technical aspects set out below - individually or in combination with each other.

[0016] According to a further development, the first compression resistance is, for example, at least a factor of 2 smaller than the second compression resistance, preferably at least a factor of 10, and particularly preferably at least a factor of 100. Initial experience has shown that the described factor values ​​define a balanced relationship between a noticeable improvement in the feeling of rest or sleep and continued sufficient integrity of the frame structure.

[0017] Furthermore, the first side element comprises, for example, a number of spring elements and / or a foam material, and preferably the second side element comprises a wood-based material. Foam materials are particularly advantageous because a large number of different foam materials with specific compression strengths are known, enabling the desired compression resistance of the first side element, or of a section thereof, to be achieved. To realize a specific compression resistance, the dimensions of the first side element can preferably be determined, for example, by specifically defining the width of the first side element in a cross-sectional plane that is oriented transversely to the longitudinal axis of the first side element.

[0018] Theoretically, there are few limits to the design of the base of a substructure. In practice, however, essentially rectangular dimensions are particularly common, especially an elongated substructure. According to an exemplary embodiment, at least two side elements of the plurality of side elements, designated as long elements, have a first length, and at least two side elements of the plurality of side elements, designated as short elements, have a shorter second length. The short elements serve in particular to form the end faces of the substructure. It is preferred that at least one first long element has the first compression resistance and a second long element has the second compression resistance.

[0019] According to an exemplary embodiment, the end faces are designed in such a way that they provide a substructure width of at least 60 cm, in particular a width of at least 70 cm, where the width is defined as the distance between the outer edge of the first long element and the outer edge of the second long element.

[0020] Preferably, the spring assembly has a third compression resistance, wherein the third compression resistance is preferably essentially the same, and in particular the same in magnitude, as the first compression resistance. By deforming the first side element and the spring assembly in a similar manner, particularly in magnitude, under a weight load acting towards the standing surface, the user is afforded improved comfort while resting or sleeping.

[0021] Furthermore, a number of side elements preferably surround the spring assembly circumferentially, so that in a user arrangement the spring assembly is visually concealed from above by a mattress and laterally by the number of side elements. In particular, all side elements create a frame structure that circumferentially surrounds the spring assembly.

[0022] Following a further development measure, for example, a number of the numerous side elements each have an upper edge with an edge surface, and the spring mechanism creates a support surface, whereby the edge surface and the support surface are preferably arranged in a common support plane. The support plane is expediently offset against the direction of gravity and essentially parallel to the standing plane. The common support plane ensures that a number of mattresses can be stored in the same plane, which contributes to increased comfort.

[0023] The presented substructure, in particular the frame structure, can, for example, rest directly on a surface. However, especially for ventilation reasons, a number of foot elements are preferred, which support the spring assembly at a distance from the surface. A number of foot elements are attached, for example, to the frame structure and / or to a support structure to be explained later.

[0024] Furthermore, a covering preferably comprises a number of side elements of the plurality of side elements and the spring mechanism. This conveniently creates, for example, a single, easily handled unit. In addition, the covering supports the side elements and promotes a visually appealing overall appearance.

[0025] Preferably, the substructure comprises a support structure which, together with a number of side elements, forms a receiving space in which the spring assembly is arranged, particularly in such a way that a trough-like receiving space is created. The support structure includes, for example, a number of slats, base plates, spring rods, support elements, and / or similar structural elements which, in a functional arrangement, are configured to support the spring assembly. In particular, a radially inwardly directed collar and / or a number of radially inwardly directed projections, which are attached, for example, to the frame structure or to a number of side elements, provide a particularly simple means of mounting the spring assembly.

[0026] Following a further development, for example, a number of side elements of the multitude of side elements exhibit the second compression resistance, and these second side elements preferably together with the support structure create a self-supporting unit which, taking into account the intended purpose, is designed to be sufficiently deformation-resistant and / or torsionally stiff, so that advantageously no further significant measures are required to strengthen the construction and the substructure as such can be handled without damage.

[0027] Preferably, the spring assembly and / or a number of first side elements comprise a number of spring elements. The number of spring elements are, for example, made from a continuous wire or connected to one another via steel wires. It is also possible that a number of spring elements are individually or grouped packaged and connected to one another via these packages.

[0028] For example, the spring assembly incorporates several foam materials, which are either single- or multi-layered. The advantages of using foam materials have already been explained and are directly applicable to the application of a spring assembly.

[0029] According to a second aspect, the presented invention relates to a bed, in particular a box spring bed, with a plurality of base units, each comprising a frame structure with a plurality of side elements and a spring assembly, and which provide a number of mattress-supporting surfaces, wherein preferably the support surfaces are arranged in a common support plane, wherein at least two base units of the plurality of base units have a number of the features described herein. For connecting the base units, for example, metal clamps have proven to be particularly reliable in practice.

[0030] The advantages of using multiple bed bases, especially for beds with a footprint exceeding 200 cm x 140 cm, stem from logistical considerations. As the bed base increases in size, handling a single, uniform base becomes more cumbersome and expensive. Instead, combining smaller bases on-site into a single, modular unit simplifies handling and reduces transportation costs.

[0031] In a particularly preferred embodiment, the first side element of the first substructure and the first side element of the second substructure are arranged adjacent to each other, i.e., with a distance of less than 10 cm. For example, the aforementioned first side elements also run parallel to each other.

[0032] Preferably, a dividing line runs between the aforementioned first side elements, the dividing line essentially lying in a bed center plane that is oriented perpendicular to the standing plane and arranged in a central axis of the bed. This advantageously allows for the realization of a mattress base with a compression resistance that is essentially homogeneously distributed over the surface.

[0033] According to a further training measure, it may be provided that a number of foot elements are arranged in a vertical plane that runs along the central axis.

[0034] Further features, details and advantages of the invention will become apparent from the wording of the claims and from the following description of exemplary embodiments with reference to the purely schematic drawings, whereby individual features or a combination of features of the illustrated exemplary embodiments can also be realized independently of the other configuration. This shows Fig. 1 A cross-sectional view of an exemplary representation of a box spring bed.

[0035] An exemplary embodiment of a box spring bed 101 in a typical usage arrangement shows Fig. Figure 1 shows a cross-sectional view. Two substructures 1 are arranged adjacent to each other and connected to form a single unit by several clamps (not shown for illustrative purposes). Each substructure 1 has a width of 100 cm, creating a bed base of approximately 200 cm x 200 cm.

[0036] The described substructure devices 1 have a rectangular, elongated base body supported on several foot elements 13. A frame structure 3 comprises two side elements 5, designated as long elements 55, and two end-forming side elements 5, designated as short elements. For illustrative purposes, the short elements are shown in Fig. 1 not recognizable. The side elements 5 each surround an internal spring device 7 with a spring core circumferentially in a spring plane FE, so that these are not visible from the outside.

[0037] Essentially, each long element 55 of the two substructure devices 1 forms a first side element 51, which is characterized by the fact that it exerts a first compression resistance against a weight load F acting towards the support plane. In the illustrated arrangement, the two first side elements 51 of the two substructure devices 1 are aligned facing each other and run parallel to each other. The further long elements 55 and the short elements form second side elements 53, which exhibit a higher compression resistance.

[0038] A dividing line 103 between the first side elements 51 of the base assemblies 1 runs in a bed center plane ME, which is arranged in a central axis of the box spring bed 101. Due to the essentially central arrangement of the first side elements 51 of the base assemblies 1, locally homogeneously distributed compression resistances are provided in the center of the bed 101, which do not diverge significantly from the spring action of the respective adjacent spring assemblies 7. This ensures that, despite the central arrangement of the first side elements 51, a person handling the bed experiences no perceptible impairment of rest or sleeping comfort.

[0039] All of the side elements 5 of the second set of side elements 53 comprise a sheet-like wood-based material. In contrast, the first side elements 51 comprise a foam material and are correspondingly larger than the second side elements 53, in particular wider. The compression strength of the foam material, and thus the compression resistance of the first side elements 51, is at least 100 times lower than the compression resistance of the second side elements 53.

[0040] The first and second side elements 51, 53 of the substructure devices 1 each have an upper edge with an edge surface which, together with the spring assembly 7, is covered by a cover 9, among other reasons for aesthetic purposes. Thus, the edge surfaces and the upper surface of the spring assembly 7 create support surfaces 11 for the mattress 105 in a common support plane LE. The support plane LE is spaced apart from the base plane AE. In the illustrated embodiment, the mattress 105 is shown in a simplified form for illustrative purposes. A topper 107 is also arranged on top of the mattress 105.

[0041] In Fig.Figure 1 also shows a base plate forming a support structure 15. The support structure 15, or the base plate, together with the frame structure 3, creates a trough-like receiving space 17 in which the spring assembly 7 is arranged. The second side elements 53 and the base plate are torsionally rigidly connected to each other and are sufficiently dimensioned so that they form a self-supporting unit.

[0042] Each substructure device 1 also has a covering 19 which surrounds all first and second side elements 51, 53 and the cover 9.

[0043] The invention is not limited to one of the embodiments described above, but can be modified in many ways.

[0044] For the purposes of explaining the present invention, it should be noted that the terms "first" and "second" are used primarily for the purpose of differentiation and should not be interpreted as directly indicating or implying quantitative limitations. Furthermore, it should be noted that the orientations or positional relationships indicated by the terms "above," "below," "inside," and "outside" are based on a preferred arrangement of use of the invention and thus serve primarily to improve clarity.
