Description

[0001] Base element for a mattress, base and a base system

[0002] Description

[0003] The invention relates to a base spring element for a mattress according to claim 1. Furthermore, the invention relates to a base spring according to claim 14. Furthermore, the invention relates to a base spring system according to claim 16.

[0004] The base elements and base suspensions referred to here are elastic and / or springy supports for mattresses or similar upholstery of beds, sleeping berths, loungers, armchairs, strollers or the like.

[0005] Various spring bases and bases of the type mentioned above are known. These bases and bases differ primarily in their spring characteristics. The spring characteristics decisively influence the sleeping, lying, or sitting comfort of beds, loungers, chairs, or the like equipped with such spring bases and bases. Conventional bases support the mattress or upholstery unevenly and do not offer individually adjustable comfort to the person lying or sitting on the mattress or upholstery.

[0006] The invention is based on the object of creating a base suspension element and a base suspension, in particular for a mattress or upholstery of a piece of furniture for sleeping, sitting or lying down, which ensure improved and individually adjustable spring characteristics for stimulating micro-movements (MiS microstimulation). A base suspension element for solving this object has the features of claim 1. Accordingly, it is provided that a base suspension element for a mattress or upholstery of a piece of furniture for sleeping, sitting or lying down has at least two support bodies. These support bodies are preferably coupled to a base via a spring body, wherein the at least two support bodies are arranged opposite one another and symmetrically to a longitudinal axis of the spring body and are connected to the spring body via a common flexible web that extends parallel to a longitudinal axis of the spring body.The arms of the support bodies can preferably be suspended from the lower end of the bar or, if the bar is arranged above the spring bodies, attached to the bar. As an alternative to the bar, the articulated connection of the support bodies to the spring bodies can also be achieved via a pivot bearing. When a support body is subjected to pressure, the two support bodies pivot together but in opposite directions around their longitudinal axis. The design of the base spring elements allows the two support bodies to tilt in opposite directions, which can increase sitting or lying comfort for a person. The tilting movement of the two support bodies can stimulate the person by applying pressure to one support body through the other support body.This simultaneous MiS microstimulation increases both comfort and blood circulation to the part of the body sitting or lying on the base. Micro-movement stimulation converts the user's movements into micro-fine counter-movements via the suspension. A base for a base system can be assembled from a variety of base elements.

[0007] The invention preferably also provides that the spring body is reversibly deformable parallel to the longitudinal axis, wherein when both support bodies are subjected to pressure, the distance between the support bodies and the base is reduced. Due to this spring property of the spring body, the tilting or rocking movement of the two support bodies is supplemented by a joint spring action of the support bodies. The suspension of the support bodies on the spring body according to the invention and the shape of the spring body itself allow a superimposed spring and tilting movement, which has a particularly advantageous effect on the lying or sitting comfort for the person. In order to be able to ensure reversible deformation of the support bodies and the spring body even in the long term, it is provided that the aforementioned elements are made of a plastic.It is equally conceivable that the objects according to the invention are made of a metal, a composite material or wood.

[0008] Preferably, the base consists of at least two frame-like base elements, each of the base elements being connected to the spring body via at least one, preferably two, flexible connections, and the two base elements being arranged opposite one another and symmetrically to a longitudinal axis of the spring body. This symmetrical design of the base elements allows the pressure transmitted to the spring body by the support bodies to be well absorbed. The design of the base allows the base spring element to be particularly advantageously connected to a foam body, such as a mattress or upholstery. The size of the frame-like base elements corresponds at least to the size of the support bodies or is larger than the surface area of ​​the support bodies.However, embodiments are also conceivable in which the base elements are smaller and are designed asymmetrically with respect to the longitudinal axis of the spring body.

[0009] In particular, a further feature of the invention is that the support bodies are plate-shaped and the support surfaces of the support bodies are preferably convexly curved upwards and the support surfaces lie in the same horizontal plane. Due to the plate-like shape of the support surfaces, the pressure exerted by the mattress or upholstery on the base spring element can be transferred particularly well to the spring body. Due to the flat design of the support surfaces, the pressure is distributed evenly over the base spring element, whereby the rocking or springy effect of the base spring element can be generated in a particularly advantageous way for microstimulation. Not only is the pressure absorption by the base spring element particularly advantageous due to this feature, but also the tilting or spring force acting on the mattress or upholstery.In particular, the convex design of the support surfaces allows for a particularly efficient interaction between the base element and the mattress or upholstery.

[0010] Furthermore, it can preferably be provided that the support bodies are connected to the spring body via a particularly curved arm, wherein the two arms of the support bodies are preferably formed in one piece. The curved arms firstly transfer the spring force of the spring body to the support bodies and secondly the arms additionally act as a spring element. Furthermore, the spring characteristics of the sub-spring element can be changed by designing the arms in different ways, for example by varying the length, width or thickness of the arms. A special embodiment of the invention can provide that the two support bodies are connected to a common arm which is curved and connected to the spring body at its apex. Due to this symmetrical suspension of the arm on the spring body, the forces on the two support bodies act equally on the spring body.

[0011] A particular embodiment of the present invention can provide that the spring body has an elliptical cross-section transverse to the longitudinal axis, wherein in particular a major axis of the ellipse is aligned horizontally and a minor axis of the ellipse is aligned vertically. This elliptical shape of the spring body can achieve particularly advantageous spring characteristics of the base spring element. By applying vertical pressure to the support bodies, force is transferred to the spring body via the arms, resulting in vertical compression of the elliptical spring body. After the compressive force is reduced or removed, the spring body deforms back to its original shape, thereby creating the resilient effect. Alternatively, it is equally conceivable for the spring body to have a different cross-sectional shape, such as a circle, a semicircle, a polygon, or the like.

[0012] A particularly advantageous embodiment of the invention can provide that the spring body has a central cutout which is spanned by a support region, wherein the web is arranged with a first end on an underside of the support region and the arms of the support bodies extend upwards through the cutout from a second end. Through this arrangement of the web on the spring body or through this design of the spring body, the force acting on the support bodies can be transmitted particularly well to the spring body. Furthermore, this shape enables the tilting or rocking movement of the support bodies. The support region, which extends over the entire length of the spring body, can be varied in its spring characteristics by further reinforcement. Through this reinforcement, the spring body achieves the necessary stability, particularly in the cutout, to absorb and release the spring forces.

[0013] Furthermore, a further advantageous embodiment can consist in the spring body and / or the base having a receptacle for an elongated, preferably rod-like, spring element parallel to the longitudinal axis, wherein a plurality of sub-spring elements can be coupled together via this spring element. It is conceivable that a plurality of sub-spring elements can be coupled together to form groups, for example for the pelvic area or shoulder area of ​​the lying person. It is also conceivable that the sub-spring elements are coupled together via the spring elements to form a sub-spring arrangement across the entire size of the mattress. By coupling the sub-spring elements together in this way, a joint spring effect of a plurality of sub-spring elements can be achieved. Furthermore, this coupling increases the stability of all sub-spring elements.In addition to the previously described spring and tilt movements, the spring elements now also provide a combined spring action of all the base elements. This coupling of several base elements allows for a particularly comfortable and individually adjustable spring action.

[0014] Furthermore, it is conceivable according to the invention for the base elements of the base to have tapered portions or receptacles, particularly with a circular cross-section, to which connecting means can be attached, allowing a base element of an adjacent base element to be connected. This further connection of individual base elements by means of connecting means can further improve the above-described combined effect of the base elements on the mattress or upholstery. The connecting means described here contribute in particular to the stabilization of the base element.

[0015] In particular, the invention can provide that the frame-like base elements have areas with increased flexibility, in particular that two opposite areas of the base element have areas with increased flexibility. These areas of increased flexibility make it particularly easy to connect the frame-like base elements to the mattress or upholstery. For this purpose, it is conceivable that the frame-like base elements are slipped over extensions, contours, projections and / or undercuts of the mattress or upholstery. By means of short-term, reversible deformation, which is made possible by the areas of increased flexibility of the base elements, the base elements can be easily and reliably coupled to the mattress or upholstery. Likewise, the base elements can be removed from the mattress or upholstery again without great force.

[0016] Particularly preferred embodiments of the spring base elements described here are designed such that the spring body and the base together have an elliptical, triangular, trapezoidal, semicircular, or other cross-section. Depending on the application or requirements, and depending on the mattress or upholstery used, various shapes can be provided for the spring base elements. However, all embodiments have the simultaneous springy or rocking movement in common. Different spring characteristics can be achieved by varying the design of the spring base elements.

[0017] A spring base for achieving the object mentioned above has the features of claim 14. Accordingly, it is provided that the spring base has a plurality of spring base elements according to at least one of claims 1 to 13. In particular, it is conceivable for several spring base elements to be coupled together to form one or more groups, wherein the spring base elements can be coupled together via spring elements parallel to a longitudinal axis of the spring base elements and / or via connecting means perpendicular to the longitudinal axis of the spring base elements. By coupling them together, a complete spring base for a mattress or upholstery can be created, wherein the individual spring base elements provide this spring base with both a springy and stimulating effect locally and overall.In particular, through tilting movements of the individual base suspension elements, the inventive design of the base suspension elements not only has a positive effect on the spring action, but also has a stimulating effect on the person. A base suspension system for achieving the stated object has the features of claim 16. Accordingly, it is provided that the base suspension system has a base suspension according to claim 14, which comprises a plurality of base suspension elements according to at least one of claims 1 to 13. This base suspension system also has a mattress or upholstery for a piece of furniture for sleeping, sitting or lying down. This mattress or this upholstery has recesses, contours, projections and / or undercuts on an upper side, into which the base suspension elements, the spring elements and / or the connecting means can be positively integrated. Through this integration into the mattress orA spring system can be integrated into the upholstery, providing increased comfort while remaining highly flexible. This allows the spring system to be adapted to a surface, for example, or rolled up for transport.

[0018] Preferably, it can be provided that a base can be detachably coupled to a preferably mushroom- or head-like contour, and two spring bodies of the slatted base elements can be placed with a spring-loaded underside on the top side of the mattress. When the slatted base elements are integrated into the mattress or upholstery, the mattress or upholstery is clamped between the base elements and the spring body. This, and the additional connection of the individual slatted base elements, creates a non-slip connection between the components. The positive connection between the mattress or upholstery and the slatted base not only gives the entire slatted base element outstanding stability, but also flexibility, allowing the slatted base system to be folded or rolled up for transport.The ability to individually adjust the spring properties of the base and simultaneously exert microstimulation (MiS) on the person lying on the base by applying pressure to the individual base elements makes the base system particularly suitable for applications in the rehabilitation and nursing care sectors. However, the base system described here is also intended for use in private homes.

[0036] Fig. 1 shows a possible embodiment of a base suspension element 10. This base suspension element 10, together with other base suspension elements 10 that can be coupled together, serves as the base suspension 39 of a mattress 41 or upholstery. The base suspension 39, consisting of a plurality of base suspension elements 10, together with the mattress 41 or the upholstery forms a base suspension system 40. By varying the arrangement and the connections between the individual base suspension elements 10, the spring characteristics of the base suspension 39 can be adjusted individually and locally. Due to the special design of the base suspension element 10, when subjected to pressure from a lying or sitting person, it not only has a springy effect but also has a stimulating effect on the person. Therefore, the base suspension 39 orThe 40 base system is particularly suitable for use in rehabilitation and nursing care.

[0037] The base spring element 10 essentially consists of two support bodies 11, 12, a central spring body 13, and a base 14. The two support bodies 11, 12 are aligned symmetrically to a longitudinal axis 22 through the spring body 13. The plate-shaped support bodies 11, 12 each have a support surface 15, 16, which, in the embodiment shown in Fig. 1, are slightly convex upwards and lie in the same horizontal plane. Mattress elements and upholstery elements can be placed on these support surfaces 15, 16. These support surfaces 15, 16 also serve to positively clamp the mattress or upholstery (not shown) with an underside. In addition to the shape of the support surfaces 15, 16 shown here, they can also have a different shape. The support bodies 11, 12 are each attached to the spring body 13 via an arm 17, 18.The arms 17, 18 are arched and thus also contribute to the spring properties of the base spring element 10. The arms 17, 18 shown here are formed as a single piece, converging within the spring body 13 and connected by a web 19 (Fig. 4). For this purpose, the spring body 13 has a recess 20 into which the two arms 17, 18 extend and in which the web 19 is positioned. The recess 20 is spanned by a support area 21. The web 19 is attached below this support area 21. The two arms 17, 18 thus extend from the web 19 out of the spring body 13 upwards to the two support bodies 11, 12.

[0038] In the embodiment shown in Fig. 1, the spring body 13 has an elliptical cross-section perpendicular to the longitudinal axis 22. This cross-section provides the spring body 13 with its resilient effect. This embodiment has a receptacle 23 on its upper side, which also has an elliptical cross-section. A profile 24 can be inserted into this receptacle 23, which allows the spring properties of the base spring element 10 to be varied (Fig. 2). This additional profile 24 reinforces the spring body 13, making deformation more difficult.

[0039] In the embodiment shown in Fig. 1, the base 14 consists of two base elements 25, 26. These base elements 25, 26 are frame-like and are each flexibly attached to the spring body 13 by two connections 27. These base elements 25, 26 are also positioned and formed symmetrically to the longitudinal axis 22 on the spring body 13. On two opposite end faces, the base elements 25, 26 each have a taper 28, 29. Connecting means 30 can be detachably coupled to these tapers 28, 29, which preferably have a circular cross-section (Fig. 2). These connecting means 30 each have a plug-in, snap-in, or click connection, via which two sub-spring elements 10 can be connected to one another as shown in Fig. 4. This allows long rows of sub-spring elements 10 arranged next to one another to be formed.The circular design of the tapered portions 28, 29 allows the various base spring elements 10 to be moved or rotated relative to one another. The connecting elements 30 primarily serve to provide mechanical stability and connect the individual base spring elements 10. Furthermore, the individual base elements 25, 26 can have recesses 33 in their frame parts. These recesses 33 make the frame-like base elements 25, 26 very flexible, allowing them to be connected to the mattress or upholstery particularly easily and reliably.

[0040] Additionally, a receptacle 31 can be arranged on the base 14 and / or the spring body 13, through which a spring element 32 can be pushed through several sub-spring elements 10 or receptacles 31 (Figs. 2, 3). This spring element 32 connects several sub-spring elements 10 to one another and exerts a spring action on the thus coupled sub-spring elements 10.

[0041] As shown in Fig. 4, when a load 34 or pressure is applied, the support bodies 11, 12 perform a tilting movement, symbolized by arrow 36. In response to the load 34, the opposing support body 11, 12 moves upward in the direction of arrow 35. As a result, the application of pressure to one support body 11, 12 immediately causes stimulation by the other support body 12, 11. This tilting movement is made possible by the connection of the support bodies 11, 12 with the web 19 in the clearance 20 of the spring body 13. When both support bodies 11, 12 are loaded simultaneously according to the arrows 37 (Fig. 4), a resilient effect of the spring body 13 occurs in the direction 38 of the entire base spring element 10. The application of pressure to the base spring element 10 thus leads to a superimposed effect consisting of a rocking movement 36 and a spring movement 38.Through the optional coupling of the individual sub-suspension elements 10 by the spring element 32 and the connecting means 30, the effect is transferred to several adjacent sub-suspension elements 10, which leads to a particularly comfortable suspension for the person.

[0042] In a further embodiment according to Figs. 5 to 7, the spring element 32 is guided above the spring body 13 through the receptacle 23. By coupling the individual sub-spring elements 10 according to this embodiment, the spring bodies 13 are directly coupled to one another, so that exerting pressure on a support body 11, 12 has a direct effect on the spring body 13 of at least the adjacent sub-spring element 10. This coupling not only transfers the spring effect to adjacent sub-spring elements 10, but also the stimulating effect that occurs as a reaction to the load on the individual support bodies 11, 12. The other features of the embodiments shown in Figs. 5 to 7 are identical to the previously described embodiment and are therefore not numbered again in the figures.

[0043] Fig. 8 shows a base spring assembly 39 composed of a plurality of individual base spring elements 10. The individual base spring elements 10 are coupled to form a rectangle by a plurality of parallel spring elements 32 and by connecting means 30. In the exemplary embodiment shown in Fig. 8, not all base spring elements 10 are coupled to one another via connecting means 30. This allows groups of base spring elements 10 to be formed, each exerting a stronger or weaker spring effect locally. The spring effects of the individual base spring elements 10 can thus be adjusted locally, individually, and tailored to each individual.

[0044] 9 to 11 show a section of a possible embodiment of a base suspension system 40. In this case, several base suspension elements 10 are brought together in a form-fitting manner with a mattress 41 made of, for example, foam. The mattress 41 has several mushroom-shaped contours 42 arranged symmetrically to one another, which have an undercut 43 on an underside. To manufacture the base suspension system 40, the base suspension element 10 with its two base elements 25, 26 is guided over two adjacent mushroom-shaped contours 42, so that the frame-like base elements 25, 26 are positioned in the undercuts 43. The two support bodies 11, 12 of the base suspension element 10 are placed under pretension on an upper side 44 of the contours 42, so that a form-fitting connection between one base suspension element 10 and two adjacent contours 42 is achieved (Figs. 10, 11).Channels or elevations are formed between the individual contours 42, in which the connecting means 30 or the spring elements 32 can be placed. If necessary, additional cushions or mattress parts can be placed on the upper sides 44 of the contours 42 or on the support bodies 11, 12. Due to the flexible coupling of the individual base suspension elements 10 to one another, the base suspension system 40 is also highly flexible, which in particular enables rolling up for transport. It should be expressly pointed out that, in addition to the contours 42 shown here, other shapes are also conceivable in order to form a base suspension system 40 together with the base suspension elements 10. It is also conceivable that sensor means can be integrated into the contours 42 or into the spaces between the contours 42, in order to determine and analyze, in particular, movement behavior or a sleeping climate.

[0045] 12 to 18 show further exemplary embodiments of a base suspension element 14. What all of these exemplary embodiments have in common is that they each have two support bodies 11, 12, which are connected to a spring body 13 via two arms 17, 18 and via a web 19. This spring body 13 is in turn connected to a base 14 via connections 27 or directly forms the base 14. Just as previously shown for the exemplary embodiment according to Fig. 1, these base suspension elements 10 according to Figs. 12 to 18 can also be coupled to one another via connecting means and spring elements to form a base suspension 39. Integration into a mattress to form a base suspension system 40 is also provided for the last-mentioned exemplary embodiments, as described for the exemplary embodiment according to Fig. 1. The features of the exemplary embodiments according to Figs.12 to 18 are provided with the same reference numerals as the corresponding features of the embodiment according to Fig. 1.
