[0001] SUSPENSION FOR A RELAXING FURNITURE AND RELAXING FURNITURE

[0002] Description

[0003] The invention relates to a piece of furniture for resting, in particular a piece of furniture for sleeping or reclining, according to the preamble of claim 19. The invention also relates to a suspension system for a piece of furniture for resting according to the preamble of claim 1.

[0004] Rest furniture, especially sleeping or reclining furniture, differs significantly due to varying sleep cultures across countries and continents. Rest furniture also varies depending on its intended use, namely in homes, hotels, and hospitals, and in the automotive sector, particularly in trucks, caravans, and ships. Because of these different sleeping habits and purposes, rest furniture differs in its construction and, above all, in its requirements for suspension or support.

[0005] In popular sleep furniture, so-called slatted bed bases are used as the support for mattresses. These bases have transverse slats, especially sprung slats, which are mounted to a rigid frame using springy bearings. The frame makes the support bulky and difficult to handle. It also necessitates specially designed stands. Furthermore, the spring properties of conventional slatted bed bases are fixed and only partially adjustable. However, especially when used as a support for mattresses, it is essential to be able to address the individual needs of the person lying on the mattress and to adjust the support accordingly.

[0006] The invention is based on the objective of creating a piece of furniture for resting, as well as a suspension system for such furniture, which is modular in design and individually configurable. A suspension system for achieving this objective has the features of claim 1. Accordingly, it is provided that a suspension system for a piece of furniture for sleeping, sitting, or reclining comprises several elongated and elastic support profiles having a longitudinal axis. These support profiles are arranged parallel to one another in a plurality of configurations and extend transversely to a longitudinal axis of the furniture, similar to the slats of a conventional slatted frame. The support profiles are interconnected by spring elements and / or connecting elements. The entirety of the support profiles essentially forms the suspension system for, for example, a mattress. According to the invention, it is provided that a first group of support profiles are arranged parallel to one another and form a common upper plane.Furthermore, a second group of support profiles is arranged parallel to each other, forming a common lower level. The upper and lower levels are parallel to each other and spaced apart. The two groups thus form a kind of sandwich structure, with the space between them essentially empty. The mattress, or parts of a mattress, are placed on the upper level, or on the first group of support profiles, while the second group of support profiles can be placed on virtually any other surface. The support profiles of the first group are connected to the support profiles of the second group via spring elements. This division of the sprung base into a first and a second level allows the forces acting on the sprung base and the mattress to be distributed in a particularly advantageous manner, resulting in exceptionally high sleeping comfort.By varying the properties of the individual levels and the suspension elements, a high degree of individualization or person-specific adaptation of the suspension properties can be achieved.

[0007] Preferably, a spring element connects one or two support profiles of the first group with two support profiles in the second group, wherein the first group is arranged above the second group and preferably forms a receiving surface for at least one mattress. This connection, linking, or networking of the two levels allows for particularly advantageous damping characteristics of the suspension system. It is conceivable that two support profiles of the lower level are each connected to a support profile of the upper level via the spring elements. Likewise, it is conceivable that two support profiles of the lower level are each connected to two support profiles in the upper level. Furthermore, it is essential for the stability of the suspension system that, in the longitudinal direction, or...In the direction of a longitudinal axis of the suspension system, successive spring elements each reach a common support profile, thus creating a linkage of successive support profiles. For example, if a first spring element is connected to the first and second support profiles of the lower level, then a second spring element is connected to the second and third support profiles of the lower level. Similarly, the spring elements can be connected to the support profiles in the upper level.

[0008] Preferably, the two groups are also arranged parallel to each other, with a support profile of the first group positioned above a gap between two support profiles of the second group. Since the individual support profiles are spaced apart from each other, a gap is created between them. One embodiment of the suspension system can provide that the support profiles of the first group are arranged precisely above this gap. This relative arrangement allows a spring element to be particularly advantageously connected to one support profile of the first group by means of two support profiles of the second group. In this embodiment, it is conceivable that the first group of support profiles has two fewer support profiles than the second group.

[0009] Furthermore, according to the invention, it is conceivable that a suspension element connects two support profiles of the second group to one support profile of the first group, and that another suspension element connects one of the two support profiles of the second group to another support profile of the second group to another support profile of the first group. Likewise, it is conceivable that a suspension element is connected to three support profiles of the second group.

[0010] Another embodiment of the invention provides that the spring element has at least one, preferably two, springing means, and that the support profiles connected to the spring element are reversibly movable out of the first or second plane by the application of force and deformation of the springing means. These springing means can be rings or ring segments oriented transversely to the longitudinal axis of the support profiles and reversibly compressed by a vertical force. It is also conceivable that a spring element comprises several of these circular or zigzag-shaped springing means, arranged one above the other. The spring or damping characteristics of the spring elements can be adjusted by the type and size of these means.For example, a circular spring element with a large diameter has a different spring characteristic than a circular spring element with a smaller diameter.

[0011] In particular, it is provided that the support profiles of the first and / or second group are connected to three, four, five, or more spring elements, wherein the spring elements are spaced apart from one another, preferably at equal intervals, along the longitudinal axis of the support profiles. It has proven particularly advantageous to position one spring element at each end of the support profiles to ensure the necessary stability of the spring system. The remaining spring elements are then arranged at regular or random intervals between these two outer spring elements. Depending on the requirements, these inner spring elements can be arranged at various positions along the longitudinal axis of the support profiles. Preferably, the spring elements can be slid back and forth along the longitudinal axis of the support profiles without requiring significant force.

[0012] A particularly advantageous embodiment of the invention provides that the spring element has receptacles with which the spring element can be connected to the support profiles. These receptacles allow the spring element to be slid or clicked onto the support profiles with sufficient force to fix the spring element to the support profiles, but also to allow the spring element to be moved back and forth on the support profiles to achieve individual position adjustment.

[0013] Furthermore, it is conceivable that adjacent support profiles of the second group are connected to each other via connecting elements, and / or that adjacent support profiles of the first group are connected to each other via connecting elements. These clamp-like connecting elements can further increase the stability of the suspension by directly coupling the support profiles of the first or second group. This coupling can be rigid, preventing the two support profiles from moving relative to each other, or flexible, allowing for dynamic behavior of the lower or upper level within the limits of the support profiles' flexibility.

[0014] Preferably, springs with wing-shaped contact surfaces can also be attached to the support profiles of the first group, onto which the mattress can be placed. These wings allow the mattress's contact surface to be moved away from the support profiles, thus enabling easy customization of the mattress's contact area. These contact surfaces can be clipped onto the support profiles in a similar way to the spring elements. It is conceivable that each support profile or pair of support profiles of the first group can be assigned a plurality, preferably four, five, six, seven, or eight, of such contact surfaces. These contact surfaces can have one, two, or even four individual surfaces on which the mattress can be placed. Furthermore, these contact surfaces can also be resilient, providing an additional damping option.Furthermore, it is conceivable that the contact surfaces are convex in the direction of the mattress, so that even with a slight shift in position of the spring elements or the contact surface or the mattress, sufficient support of the contact surface on the mattress can be ensured.

[0015] Preferably, the invention further provides that each individual spring element comprises at least one foam body, which modifies the spring characteristic of the spring element. The foam body is inserted into the spring element to adjust the spring characteristic. The foam body can have additional undercuts that correspond to the spring elements or the springing means, thereby enabling the foam body to be fixed within the spring element. These foam bodies can be individually adapted for each area of ​​the suspension system. Since the manufacture and modification of the foam bodies are very simple compared to modifying the spring elements, the spring properties of the suspension system can be modified in a very simple and cost-effective manner by using the foam bodies.Furthermore, according to the invention, it is conceivable that two, three, four, or all spring elements, arranged successively transversely to the longitudinal axis of the support profiles in the suspension system, comprise a foam block that modifies the spring characteristic of the spring element. Several spring elements can be flexibly arranged on this foam block, thereby not only allowing the spring characteristic of the suspension system to be adjusted but also achieving an increased degree of stability. Here, too, it is particularly advantageous that the foam block is especially easy and flexible to manufacture.

[0016] It is preferably conceivable that the size, in particular the height, hardness, and shape, as well as the number and position of the foam body and the foam block, can be changed, preferably adjusted, depending on the requirements of the suspension. Furthermore, it is provided that the foam body and the foam block have at least one undercut to fix the spring element(s).

[0017] According to the invention, the support profiles can be made of a fiber composite material. The diameter of the profiles can be 1, 2, or 3 cm. The cross-section of the profiles is round, oval, or elliptical. The length of the support profiles can be 80 cm, 100 cm, 120 cm, 40 cm, 160 cm, 180 cm, or 200 cm. It is also conceivable, particularly for the second group of support profiles, that they have a length of only 1 cm, 2 cm, 5 cm, 10 cm, or 20 cm. With this shorter length, the support profiles serve to support the spring elements on a lower shelf. Furthermore, it is conceivable that the support profiles have different dimensions. It is also conceivable that the support profiles are made of a different material, such as a plastic or a natural product like bamboo.

[0018] A piece of furniture designed to solve the aforementioned problem has the features of claim 19. Accordingly, this piece of furniture is provided to have a sprung base according to claims 1 to 18. It is provided that the sprung base is at least partially integrated into the mattress. Thus, the mattress is not placed on the sprung base, as is known from conventional furniture, but rather the mattress encloses at least the majority of the sprung base, thereby creating an integral piece of furniture that can be individually adapted to the requirements of a person.

[0019] Preferably, the mattress consists of several parts and can be arranged around the slatted base. For example, the mattress could be composed of at least one top part, at least one bottom part, at least two side parts, and at least two end parts, or at least one frame part. The frame part is a type of frame into which the slatted base can be inserted. Particularly for manufacturing, but also for cleaning, it is advantageous that the mattress can be assembled from several individual parts and can be disassembled and reassembled, for example, by means of hook-and-loop fasteners or zippers. Another embodiment of the invention provides that the mattress forms a kind of cover into which the slatted base can be inserted.

[0054] Figure 1 shows a highly schematic embodiment of a possible embodiment of a piece of furniture 10 for resting. This piece of furniture 10 can be a bed or a piece of sleeping or lounging furniture. It is equally conceivable that it could also be the seat of an armchair, sofa, or chair. This piece of furniture 10 essentially consists of a mattress 11 and a sprung base 12. According to the embodiment shown here as an example, the mattress 11 and the sprung base 12 can be supported by feet 13 or raised off the floor. While the mattress 11 allows a person to sit or lie on the piece of furniture 10, the sprung base 12 improves the cushioning or suspension of the mattress 11.

[0055] The support structure 12 can, as indicated in Fig. 1, be arranged across its entire surface beneath the mattress 11. Accordingly, the size of the support structure 12 corresponds to the size of the mattress 11. In this embodiment, a type of frame 14 can also be arranged beneath the support structure 12, upon which the support structure 12 rests.

[0056] Another embodiment, shown in Fig. 2, provides that the sprung base 12 is integrated into the mattress 11. In this embodiment, the sprung base 12 is enclosed by two end pieces 15 and two side pieces 16. Furthermore, the sprung base 12 is enclosed by a base piece (not shown) and a top piece. The entirety of these mattress components then forms the mattress 11. In this embodiment, the surface area of ​​the sprung base 12 is at least slightly smaller than the surface area of ​​the mattress 11. It is also conceivable that the end pieces 15 and side pieces 16 are formed in one piece and create a kind of frame into which the sprung base 12 can be placed.

[0057] Figures 3a to 3d illustrate a first embodiment of a sprung base 12. The sprung base 12 essentially serves to improve the sleeping or sitting comfort for a person lying on a mattress 11, which is arranged on the sprung base 12. This improvement is intended to be achieved by allowing the sprung base 12 described here to be customized to meet the individual needs of the person. For this purpose, the sprung base 12 has a plurality of elongated and elastic support profiles 17 arranged side by side. Figure 3a shows that these support profiles 17 are rod-like and arranged parallel to each other. The arrow 18 shown in Figure 3a symbolizes a longitudinal axis 18 of a support profile 17. This longitudinal axis 18 of the support profiles 17 is oriented transversely or perpendicularly to the arrow 19, which in turn represents a longitudinal axis of the sprung base 12.of the resting furniture 10 is meant to symbolize.

[0058] The suspension system 12 has two groups of support profiles 17, namely a first group 20 and a second group 21. The first group 20 of support profiles 17 forms an upper level 22 of the suspension system 12, while the second group 21 of support profiles 17 forms a lower level 23. Both levels 22 and 23 are each formed by a plurality of parallel support profiles 17, with the support profiles 17 of each group lying in the same plane. The two levels 22 and 23 are spaced parallel to each other. The support profiles 17 of the upper level 22 and the lower level 23 are also aligned parallel to each other.

[0059] In the embodiment shown in Fig. 3a, the support profiles 17 of the upper level 22 are each positioned above a gap 24 formed by two adjacent support profiles 17 of the lower level 23. Due to this arrangement, the upper level 22 has two fewer support profiles 17 than the lower level 23. As will be shown below, however, embodiments are also conceivable in which the number of support profiles 17 of the upper and lower levels 22, 23 is identical. This arrangement of the support profiles 17 is particularly evident from the enlargement shown in Fig. 3b. Fig. 3b also shows that the support profiles 17 of the upper level 22 and the lower level 23 are each coupled to one another by spring elements 25. In the embodiment shown in the aforementioned figures, a spring element 25 couples one support profile 17 of the first group 20 or the second group 23.The upper level 22 is connected to two support profiles of the second group 21, respectively, of the lower level 23. A further special feature of this embodiment is that, with the exception of the outermost support profiles 17 of the lower level 23, each support profile 17 of the lower level 23 is coupled to its two adjacent support profiles 17 via the spring elements 25. This continuous arrangement of the support profiles 17 of the lower level 23 creates a linkage or coupling via the support profiles 17 of the lower level 23, ultimately forming the spring suspension 12. In the embodiment shown in Figures 3a to 3d, each support profile 17 of the upper level 22 is coupled to four spring elements 25, and each support profile 17, apart from the outermost support profiles 17, of the lower level 23 is coupled to eight spring elements 25.It can be seen that the guide elements 25 of adjacent support profiles 17 are positioned close together, resulting in four consecutive groups of guide elements 25 along the direction of arrow 19. The spring elements 25 are generally arranged at regular or equal intervals. However, it is also conceivable that in certain areas, for example, the area where the shoulders or pelvis will later rest, several spring elements 25 are arranged, while in other areas there are fewer. This individual positioning of spring elements allows the spring action of the suspension 12 to be adjusted precisely.

[0060] The guide elements 25 according to the embodiment shown in Figures 3a to 3d are kidney-shaped or oval and have three recesses 26 into which the support profiles 17 can be slid, clicked, or pressed. However, this connection is designed such that the guide elements 25 can be removed from the support profiles 17 without the need for a special tool or increased force, or can be moved back and forth along the longitudinal axis 18 on the support profiles 17 to create an individual support for the mattress 11.

[0061] The special shape of the spring elements 25 gives the suspension system 12 a high degree of flexibility perpendicular to a plane defined by arrows 18 and 19. This flexibility is primarily generated by the interaction of the flexible support profiles 17 and the spring properties of the spring elements 25. As soon as a force is applied perpendicularly to the upper plane 22 of the suspension system 12, the suspension system 12, or rather the support profiles 17 and the spring elements 25, compress around this point. As soon as the applied force is released, the suspension system 12 reversibly returns to its original shape. The connection between the two planes 22 and 23 via the spring elements 25 allows the restoring force to be transferred directly to the mattress 11. This connection enables both point-source and area-based compression, as well as point-source and area-based support of the suspension system 12.Unlike a conventional slatted frame, the suspension system 12 described here is not only suspended at the long sides, but is supported along the entire length of the support profiles 17. This means that the suspension system 12 partially replaces the function of a mattress 11, allowing the mattress 11 to be simplified in its structure, which can, for example, lead to weight savings. It should also be emphasized that the suspension system 12 described here can be used in conventional bed frames. Figure 3c clearly illustrates the arrangement of the support profiles 17 in two parallel planes 22 and 23. The distance between these two planes 22, 23 can range from a few centimeters to 10 cm, 15 cm, or even 20 cm. It should be noted that both the diameter of the support profiles 17 and the dimensions of the suspension elements 25 can differ from those shown here.Figure 3D shows a view of the end face of the suspension 12. This view shows that the suspension elements 25 are arranged in pairs on adjacent support profiles 17. This arrangement not only optimizes the networking or linking of the two planes 22, 23, but also the connection of the support profiles 17 in the direction of arrow 19.

[0062] Figures 4a to 4c illustrate a further embodiment of a spring suspension 12. For clarity, the same reference numerals are used for all the embodiments sketched here, although it should be noted that these reference numerals are used for different embodiments, but the features described by these reference numerals have the same technical function or effect.

[0063] The embodiment shown in Figures 4a to 4c is essentially identical to the embodiment described above in Figures 3a to 3d. The only difference is that the support profiles 17 of the lower level 23 are not continuous, but rather pin-like. This embodiment for the suspension 12 is suitable for placement on a closed support surface. In this case, the continuous support profiles 17 described above would be superfluous. Nevertheless, the multitude of pin-like support profiles 17 of the lower level 23 produces the same technical effect as described previously for the other embodiment. Figures 4b and 4c further illustrate the variation caused by the shortened support profiles 17 of the lower level 23.

[0064] Figures 5a to 5c illustrate another embodiment of a suspension system 12. This embodiment is also similar in its essential features to the embodiment discussed first. A key difference in this embodiment is that the suspension elements 25 are not arranged in pairs along the support profiles 17, but offset from one another. Thus, successive support profiles 17 of the upper level 22 are alternately assigned three or four suspension elements 25, and the support profiles 17 of the lower level are assigned six or seven suspension elements 25. This offset arrangement of the suspension elements 25 also allows for area-wide suspension, although the number of suspension elements 25 is reduced. Furthermore, it is particularly evident from Figures 5b and 5c that the structure of the suspension elements 25 differs from that of the embodiment according to Figures 3a to 3d. The structure shown, for example, in Figure 3a, is different from that shown in Figure 3b.The spring element 25 shown in Figure 5c has, in addition to an elliptical body 27 to which a support profile 17 of the upper plane 22 is attached, a crescent-shaped body 28 to which both the body 27 and two support profiles 17 of the lower plane 23 are attached. Even though the arrangement of the spring elements 25 varies in this embodiment, two spring elements 25 are assigned to each of the end regions of the support profiles 17 in order to achieve the necessary stability there.

[0065] In the embodiment of the suspension 12 shown in Figures 6a to 6f, the suspension elements 25 are designed as hinges. These hinge-like suspension elements 25 have two legs, each connected to the other at one end and connected at the other end to one or two support profiles 17 of the lower plane 23 and one support profile 17 of the upper plane 22. The suspension elements have corresponding receptacles for this purpose. The apex where the two legs of the suspension elements 25 meet is directed inwards towards the interior of the suspension 12, so that when the suspension elements 25 or the suspension 12 are compressed, they move into the suspension 12 and are not moved outwards in a disruptive manner.In this embodiment as well, it is preferably provided that four suspension elements 25 are assigned to each support profile 17 of the upper level 22 and that the corresponding suspension elements 25 each connect two support profiles of the lower level 23 to each other.

[0066] This particular embodiment according to Figures 6a to 6f, in addition to the features of the other embodiments, has wing-like support surfaces 29 that can be clicked onto the support profiles 17 of the upper level 22. Figure 6d shows, by way of example, that these support surfaces 29 are convex and are connected to each other and to the support profile 17 via two legs 30. In particular, the connection of the support surfaces 29 via the legs 30 creates an additional resilient element in the suspension system 12. These support surfaces can be positioned in almost any position along the support profiles 17 of the upper level 22. Due to the convex shape of the support surfaces 29, the mattress 11 conforms particularly well to these support surfaces 29, thus achieving optimal force exchange, even when the suspension system 12 is compressed.

[0067] In the embodiment for a suspension system 12 according to Figures 7a to 7d, the hinge-like suspension elements 25 are each connected to two support profiles 17 of the first group 20 or upper level 22 and two support profiles 17 of the second group 21 or lower level 43. In particular, four suspension elements 25 are thus each connected to exactly four support profiles 17. In this embodiment, the support profiles 17 are linked in the direction of arrow 19 via additional connecting elements 31. These connecting elements 31 are arc-shaped and each has two receptacles at its ends for connection to a support profile 17. It is provided that each connecting element 31 connects two adjacent support profiles 17 that are not connected via a suspension element 25. Figures 7a to 7d show the following:Figures 7b or 7d show that these connecting elements 31 are arranged between the spring elements 25, alternating between the upper plane 22 and the lower plane 23. Of course, it is also conceivable that the connecting elements 31 are arranged between the spring elements 25 in both the upper plane 22 and the lower plane 23. The arched shape of the connecting elements 31 gives the spring suspension 12 and the support profiles 17 the flexibility necessary to react dynamically to the applied forces.

[0068] The embodiment of the invention shown in Figures 8 to 8d represents a combination of the two previously described embodiments of the suspension system 12. Here, four support profiles 17 are connected to one another by four suspension elements 25 and coupled to each other via connecting elements 31. Additionally, the support profiles 17 of the upper level 22 are assigned wing-like support surfaces 29 for receiving the mattress 11. This embodiment of the suspension system 12 thus possesses the mechanical properties of the two previously described embodiments.

[0069] Figures 9a to 9d show a specific embodiment of the suspension system 12. Specifically, the suspension elements 25 each comprise a foam body 32 integrated into the springing means, such as the kidney-shaped, elliptical, or crescent-shaped springs. The spring characteristic of the suspension elements 25 is therefore determined by the properties of the foam body 32. To enable the foam body 32 to be fixed within the suspension elements 25, it has an undercut (not shown). In the embodiment of the suspension system 12 shown, for example, in Figure 9b, each suspension element 25 has three foam bodies 32 arranged in a sandwich-like configuration and is coupled to four support profiles 17, i.e., two support profiles 17 of the upper level 22 and two support profiles 17 of the lower level 23.However, it is also conceivable that, as previously described, the suspension elements 25 are each connected only to one support profile 17 of the upper level 22 and two support profiles 17 of the lower level 23.

[0070] The connection of the support profiles 17 to one another, for example, the support profiles 17 of the lower level 23, can also be achieved, for instance, by means of shared foam bodies 32. Integrating these foam bodies 32 into the suspension elements 25 allows for particularly efficient damping of the suspension elements 25. Furthermore, adding the foam bodies 32 increases the stability of the entire suspension system 12. By varying the hardness of the foam, different damping properties can be achieved for different areas of the suspension system 12.

[0071] Figures 10a to 10d describe a modified version of a suspension system 12 according to the embodiment described above in Figures 9a to 9d. For example, Figures 10b and 10c show that the support profiles 17 of the upper level 22 and the lower level 23 are connected to each other via a common foam block 33. This foam block 33 can accommodate a plurality or all of the support profiles 17 of the lower level 23 and the upper level 22. Figure 10a shows, for example, that four rows of foam blocks 33 are associated with the support profiles 17, with the two inner foam blocks 33 having short gaps. These gaps allow the spring behavior of the suspension system 12 to be modified at specific points.Otherwise, the previously described suspension elements 25 are integrated into the foam blocks 33, allowing the support profiles 17 to be connected to the foam blocks 33 in a simple and flexible manner. In one embodiment, the foam blocks shown in Figures 10a to 10d may be composed of several of the foam bodies 32. It is conceivable that the foam bodies 32 are coupled together to form the foam blocks 33. By arranging several foam bodies 32 in series to form the foam block 33, and by varying...

[0072] With this embodiment of the suspension system 12, personalized damping can also be achieved with regard to foam hardness, which can be tailored to the individual needs of individual persons.
