Reclining system for a bed

The innovation relates to a bed system for a bed, comprising a rigid substructure containing longitudinal and transverse beams, optionally with movable parts, and a spring element arranged thereon, wherein the spring element is formed from two longitudinal, spaced-apart spring beams made of an elastic material, such as foam and/or latex, and a plurality of transverse slats connecting the spring beams and held on them in the manner of a slatted frame, and the spring beams rest on the outer, spaced-apart longitudinal beams of the substructure.

A generic lying system for a bed is known, for example, from WO 87/02559. In order to increase the comfort of lying down, the known lying system has elastic longitudinal bars, e.g. made of foam, which are divided over the entire length into individual zones with different levels of hardness in order to provide different levels of flexibility for individual areas of the lying system for certain parts of the body of a person lying on the bed. However, the formation of zones of different hardness within a continuous elastic longitudinal bar requires a great deal of manual effort and, once done, cannot be subsequently changed.

which makes it unnecessarily difficult to adapt such a lying system to the individual person.

From EP 043 9 712 Bl a bedstead or similar resting device is known which also has longitudinally running elastic spring bars made of e.g. foam, whereby in order to create different spring hardnesses the bars are provided in individual areas with recesses and/or inserts of different hardnesses.

The innovation is based on the task of making it easier and more variable, i.e. easier to adjust, to create areas of different hardness for individual parts of the body of the person lying on the bed in a lying system of the type mentioned at the beginning with a rigid and stable substructure, for example made of wood and a spring-loaded slatted frame, and to make it possible to lower the lying surface to 0, particularly in the shoulder area, by providing a particularly high level of flexibility in this area.

This object is achieved in a generic reclining system of the type mentioned at the outset according to the characterizing features of claim 1.

Advantageous embodiments of the innovation can be found in the subclaims.

The innovation proposes a bed system in which 0 the outer stable and rigid, e.g. made of wood, longitudinal beams of the substructure are made in two parts and the two parts are spaced apart from each other and the area of the shoulder area created by the spacing is assigned to a person lying on the bed and the two spaced apart longitudinal beam parts are each connected to each other by means of an elastic connecting element. In this way, a particularly

high flexibility of the lying surface is achieved, which enables a particularly high level of comfort, which can be varied to a large extent by selecting the elasticity of the elastic connecting element accordingly. This also enables greater flexibility than can be achieved by compressing the spring beam. The elastic connecting element is preferably made from a spring-yielding material such as natural rubber or latex, caoutchouc, rubber or a comparable material. The connecting element can be designed as a band or beam or as a helical spring or spring band, for example, and is fixed to the ends of the longitudinal beam parts, and can be adjusted if necessary.

In a preferred embodiment of the innovation, a connecting belt is provided as an elastic connecting element between the rigid longitudinal beam parts. Such a connecting belt can be advantageously made, for example, from a woven natural latex, a rubber band or a suitable rubber fabric or the like.

In order to ensure a sufficiently stable connection between the spaced-apart longitudinal beam parts, it is proposed that the connecting strap spans the area created by the spacing in a loop-like manner in the longitudinal extension and is held in the sides of the longitudinal beam parts facing each other. In this way, the connecting strap spans the open area between the longitudinal beam parts twice and ensures sufficient stability of the connection. Furthermore, it is possible to adjust the pre-tension of the tensioned connecting strap by adjusting the loop accordingly, so that subsequent individual adjustment of the degree of flexibility and elasticity in this area is also possible.

In order to ensure a high torsional strength of the substructure contained in the new reclining system,

The cross beams connecting the outer longitudinal beams of the substructure are advantageously arranged in such a way that a cross beam is located near each end region of the longitudinal beam parts.

In order to create a shoulder area of the bed system that is equally suitable for different body sizes and body weights, it is suggested that, with a substructure length of 2 m, as is the case with standard bed formats, the area created by the spacing should be approximately 40 to 55 cm away from the head end and should have a length of 35 to 50 cm.

To further increase the comfort of lying down and to support different parts of the body, another preferred embodiment of the innovation proposes that the substructure has a longitudinal central beam arranged centrally between the outer longitudinal beams, on which a pelvic support made of an elastic material such as foam or latex is arranged in the area associated with the pelvic area of a person lying on the bed. Due to its elastic properties, this pelvic support limits the deflection of the transverse slats of the spring element in the area of the pelvis of the person lying on the new lying system and thus ensures a somewhat greater hardness of the lying system in the area in which a large proportion of the person's body weight is resting.

Of course, as part of the innovation, it is also possible to attach additional support elements made of an elastic material to the substructure in other places where support for parts of the body is desired.

Furthermore, the invention can also be used in substructures that have movable parts, such as adjustable headrests, etc.

It is advantageous if the cross beams of the substructure are attached to the underside of the outer longitudinal beams facing away from the support side for the spring beams and the longitudinal central beam is attached to the underside of the cross beams. In this way, the longitudinal central beam is positioned lower than the outer longitudinal beams of the substructure, so that the pelvic support that can be placed on the longitudinal central beam can be designed at a higher height than the spring beams of the spring element that rest on the outer longitudinal beams if the spring beams and the pelvic support end at the same height on the top. This greater height of the pelvic support increases its effective spring travel compared to the spring beams on the outer longitudinal beams, so that the support of the pelvic area is more pronounced.

In a preferred embodiment of the innovation, the spring beams are provided with a cover and on the top of the spring beams, receiving pockets are provided on the cover into which the transverse slats of the spring element can be inserted. In this way, a simple mounting and effective connection of the transverse slats connecting the spring beams is achieved and the spring beams, together with the slats, form a spring element in the manner of a slatted frame.

The cover can be made of cotton fabric or other textile fabrics or other materials such as fleece or the like. It protects the spring bars, which are made of foam and/or latex, from damage and from strong exposure to light, which could attack or even destroy the foam structure over time.

In order to ensure a firm and permanent hold of the slatted frame-like structure made up of spring beams and transverse slats of the spring element, it is proposed that the spring beams be fixed on their inner sides facing each other

have at least one tensioning strap connecting the spring beams, by means of which they can be tensioned against each other when the cross slats are inserted. The tensioning strap can be fastened, for example, with round rods inserted into loops at the ends of the belt strap, which are fastened in corresponding loops on the cover surrounding the spring beams on the sides of the spring beams facing each other; fastenings and tensioning options using buttons, loops and buckles are also possible.

The innovation is explained in more detail below using an example embodiment in the drawing, which represents only one possible embodiment. It shows 15

Depiction

Fig. 3 is a plan view of a spring element of a

Reclining system for a bed.

As can be seen from Fig. 1 to 3, the bed system comprises a stable and rigid supporting substructure 2, e.g. made of wood, and a spring element 3 placed on top of it. As can also be seen from Fig. 1a, the substructure comprises the two outer longitudinal beams 20, 28, which are spaced apart from one another and connected to one another by means of cross beams 22a, b, c. The spring element 3 rests on the outer longitudinal beams 20, 28, as is also shown in Fig. 3.

The spring element 3 comprises two outer spring beams 30a,b running in the longitudinal extension of the bed system 1 made of an elastic material, for example natural latex, and a large number of slats 32 connecting the spring beams 30a,b and running transversely to the spring beams 30a,b. The spring beams 30a,b are provided with a cover in a manner not shown in detail and on the top of the spring beams, receiving pockets 33 are attached to the cover, for example sewn on, into which the transverse slats 32 are inserted, so that the spring beams 30a,b and the transverse slats are connected to one another in the manner of a slatted frame. The slats 32 are made of wood, for example, and are designed to be springy and easily bendable.

Furthermore, loops 35 are sewn onto the inner sides of the spring elements 30a,b facing each other on their covers, in which transverse tensioning straps 34 are fastened by means of retaining pins or the like. Using these tensioning straps 34, the two spring beams 30a,b can then be tensioned against each other in the transverse direction with the slats 32 inserted into the receiving pockets 33, so that the spring beams 30a,b and the inserted slats 32 are permanently fixed in their respective positions to form a slatted frame-like structure.

When the reclining system 1 is assembled, the spring beam 30a rests on the outer rigid longitudinal beam 20 of the substructure 2, while the spring beam 30b rests on the outer rigid longitudinal beam 28 of the substructure 2 according to Fig. 1a. Due to the elastic material properties of the spring beams 30a,b, the transverse slats 32, which are usually made of a suitable wood, are elastically held at the ends perpendicular to the lying surface they form on the spring beams 30a,b, whereby they can give way to the body weight of a person lying on the reclining system 1 due to the elasticity of their support on the elastic spring beams 30a,b.

In order to further increase this yielding of the spring element resting on the substructure 2 in the shoulder area of a person lying on the bed system 1, the outer longitudinal beams 20, 28 of the substructure 2 are each made in two parts and the corresponding longitudinal beam parts 20a,b and 28a,b are spaced apart from one another. The area S created by this spacing, which is assigned to the shoulder area of a person lying on the bed, is bridged by means of an elastic connecting element in the form of connecting straps 23, which connect the two parts 20a,b and 28a,b of the longitudinal beams 20, 28 to one another. Thus, in the area S, which is assigned to the shoulder area of the person lying on the bed, the elastic material properties of the connecting belt result in flexibility compared to the other rigid parts of the substructure 2, which allows the shoulder area of the person lying on the bed to be lowered further due to the body weight than would be the case with continuous, rigid, one-piece, external longitudinal beams 20, 28. In the area in which the spring beams 30a,b of the spring element 3 according to Fig. 3 rest on the elastic connecting belts 23 between the longitudinal beam parts 20a,b and 28a,b, these can thus bend considerably further together with the elastic connecting belts 23 and allow a corresponding lowering of the shoulder area of a person lying on the bed, so that increased lying comfort is achieved.

The elastic connecting straps 23 can be made from a variety of materials, for example from a rubber fabric or a natural rubber fabric. The fastening of the elastic connecting straps 23 to the longitudinal beam parts 20a,b or 28a,b is shown using the example of the longitudinal beam parts 20a,b in Fig. 2.

As can be seen from this Fig. 2, the connecting belt 23 is laid in a loop shape over the area S between the longitudinal beam parts 20a,b created by the spacing. The longitudinal beam part 20a has a through hole 25 near the end facing the area S, through which the connecting belt 23 is pulled, so that its two ends run on the top and bottom of the longitudinal beam part 20a in the direction of the longitudinal beam part 20b and wrap around the end area of the longitudinal beam part 20a in a loop shape. The free ends of the connecting belt 23 are each folded over to form a loop, through which a retaining bolt 24a,b, for example made of wood, is inserted. By forming corresponding fastening holes in the end area of the longitudinal beam part 20b facing the area S formed by the spacing, these holding pins 24a,b are attached to the longitudinal beam part 20b. For example, the holding pin 24a is inserted through a fitting hole in the side surfaces of the longitudinal beam part 20b in a manner not shown in detail and is thus held, while the holding pin 24b rests on the underside of the longitudinal beam part 20b and projects beyond the hole 26 on both sides, so that it prevents the connecting belt 23 from slipping out of the hole 26. The connecting belt 23 is thus laid twice over the area S created by the spacing, in which the shoulder area of the person lying on the bed is lowered, and thus has sufficient strength.

In order to ensure good stability of the substructure 2 despite the flexible connecting straps 23 between the longitudinal beam parts 20a,b and 28a,b, the cross beams 22a,b,c connecting the longitudinal beams 20, 28 are arranged in such a way that a cross beam is arranged and fastened near each end area of the longitudinal beam parts 20a,b and 28a,b. Furthermore, a longitudinal central beam 21 runs centrally between the outer longitudinal beams 20, 28, so that in conjunction with the cross beams 22a,b,c a torsion-resistant substructure 2 is formed despite the flexible connecting straps 23 in the

Area S is created. The connections between the longitudinal, central and transverse beams can be made, for example, by means of tenoning and gluing in a known manner.

In order to achieve the most universal suitability possible of the shoulder lowering in the area S for different body sizes and body weights of people with the substructure 2, the area S created by the spacing is approximately 40 to 55 cm away from the head side K of the substructure 2 and is designed over a length of 35 to 50 cm.

In order to create a further improved lying comfort, moreover, as can be seen from Fig. 1a, in the area B assigned to the pelvic area of a person lying on the bed, a pelvic support 31 made of an elastic material, such as foam or natural latex, preferably made of the same material as the spring bars 30a,b of the spring element.3, is placed on the central bar 21 in the desired position.

When the spring element 3 is placed on this substructure according to Fig. 3, whereby the spring beams 30a,b are placed on the longitudinal beams 20, 28 or their longitudinal beam parts 20a,b, 28a,b and the connecting belts 23 connecting them, the transverse slats 32 of the spring element 3 come to rest on the pelvic support 31 in area B, so that their deflection in this area is limited by the spring effect of the pelvic support 31 and the pelvic area of a person lying on the bed is given effective support. The pelvic support 31 can be attached in the desired position, for example by means of Velcro fasteners or the like, to the central beam 21 of the substructure 2 and secured against slipping.

It is further proposed to construct the substructure 2 in such a way that the cross beams 22a,b,c of the substructure are attached to the underside of the outer longitudinal beam parts 20a,b, 28a,b facing away from the support side for the spring beams 30a,b.

are, compare Fig. 2, and the longitudinal central beam 21 - not shown in Fig. 2 - is attached to the underside of the cross beams 22a,b,c. In this way, the central beam 21 is at a lower level than the outer longitudinal beam parts 20a ₇ b, 28a,b and the pelvic support 31 placed on the central beam can have a greater height than the spring beams 30a,b and yet be flush with them, so that the effective spring travel of the pelvic support 31 can be increased and the support in the area B facing the pelvis of the person lying on the bed is improved.

In this way, an integrated bed system 1 is created for a bed, consisting of a spring element 3 and a substructure 2. The main benefit is the elastic shoulder lowering integrated into the substructure in area S. Furthermore, pelvic support is achieved by a foam element as a pelvic support 31 in area B, which is placed on the center beam 21 of the substructure 2 at the desired location. The shoulder lowering only works with the coordinated elastic spring element 3, which has spring beams 3 0a,b made of a suitable foam or natural latex extending over the entire length of the bed on the left and right.
