Definitions

  • the invention relates to a spring base for upholstered furniture with a frame and a number of spring slats spanning the base area bordered by the frame and held on two opposing bars of the frame in a juxtaposition, of which at least two are attached as bearing spring slats directly or with the interposition of spring slat holders to the spars are connected, between which two spring slats at least one spring slat not supported on the spar side is arranged, the spring slat group formed from the two spring slats and the at least one spring slat arranged between them being connected by suspension means extending between the end sections of these spring slats.
  • a spring base can be designed as a slatted frame.
  • a slatted frame includes a frame and a number of slats.
  • the spring slats span the base area bordered by the frame.
  • the frame is formed by two longitudinal bars and two transverse bars, the longitudinal bars determining the length of the slatted frame and the transverse bars determining the width of the same.
  • the slats span the base of this frame parallel to the crossbars. The spring slats are thus held on the opposite longitudinal beams with such a sprung base.
  • the slats of such a slatted frame determine the suspension comfort.
  • Slats made of wood or composite materials are used as slats.
  • double spring slats are sometimes also used, which are arranged in a stacked arrangement relative to one another.
  • the two slats of such a double slat are held together by two cuffs enclosing them. These are in the longitudinal direction of the slats displaceable in order to be able to set the compression hardness of such a spring strip in this way. If these hardness adjustment slides are more in the middle area of the slats, the deflection behavior is softer than if they are in the outer areas of the slats.
  • the slats can be connected directly to the spar.
  • the spring slats are in many cases connected to the bars of the frame with the interposition of spring slat holders.
  • the slat holders are made of or at least with the participation of elastomeric materials, so that they are involved in the compression work.
  • Spring slat holders also allow the spring slat carried by them to be adjusted over a few angular degrees about a pivot axis running below the spring slat. Due to the elastomeric components of such a spring strip holder, it resumes its original position after being adjusted by a load.
  • zones can be provided within the lower spring area that react more softly than others in terms of their deflection.
  • softer zones are typically located in the shoulder area and/or in the hip area.
  • EP 2 392 232 B1 proposed to arrange at least one spring slat not connected to the spars between two spring slats connected to a spar, hereinafter referred to as support spring slats.
  • This at least one spring slat is connected to the two bearing spring slats with suspension means and is thus carried by them.
  • an elastic element arranged between two adjacent spring slats is used as the support means. This is elastic in the direction of its longitudinal extension and in the transverse direction.
  • the suspension spring slats are connected to the spars of the frame in such a way that they are perpendicular to the spar and parallel to the longitudinal extension about an axis are pivotally mounted on this female connector. Since the spring slats arranged between two support spring slats are not supported on the spar side, their deflection behavior depends on the elastic elements connecting them. Although the deflection behavior of these spring slats depends on the design of the elastic elements, it is typically significantly softer than the deflection behavior of the supporting spring slats carrying these spring slats.
  • each spring slat requires an end support element to which the intermediate elastic element is connected. Since it is known that the original elasticity of elastomers decreases over time, it would also be desirable to build on this EP 2 392 232 B1 previously known concept with respect to its deflection behavior more permanent spring support could be provided.
  • Another generic base is already from the DE 20 2013 007446 U1 known.
  • the invention is therefore based on the object of further developing a spring base of the type mentioned at the outset in such a way that not only does the deflection behavior remain the same over a longer period of time, but it is also easier to manufacture and assemble and in which the possibility consists in influencing the deflection behavior of the at least one spring slat held by two support spring slats with simple means.
  • each support means is elastically flexible, but has high tensile strength and extends from the first support spring strip via the at least one spring slat carried by this extends to the second spring slat and in which the spring slats connected by the suspension element each have a suspension element guide in which the suspension element is guided so that it can be displaced in the direction of its longitudinal extent and is held in a form-fitting manner in the radial direction relative to the suspension element.
  • the suspension element has tensile strength in the direction of its longitudinal extension and is elastically flexible in the transverse direction. that means: flexible.
  • This suspension means can thus be bent in the transverse direction to the longitudinal extension and, due to its elastic, flexible property, automatically returns to its starting position after the end of the loading situation, and thus also the spring slats carried by it.
  • this support means is typically located in the area of the longitudinal end sections of the slats, is mounted in the first and second slats and extends continuously between them and thus also over the slats located between the two slats.
  • each spring slat has a suspension element guide.
  • the support means is guided in a longitudinally axial direction.
  • the suspension element can therefore be moved in such a suspension element guide in the direction of its longitudinal extent.
  • the suspension element In the suspension element guide, the suspension element is held in a form-fitting manner in its radial direction and thus in and against the deflection direction. This means that the suspension elements cannot be separated from such a suspension element guide in the radial direction.
  • suspension element guides that are not closed circumferentially, this means that the opening following the longitudinal extent has a smaller opening width than the diameter of the suspension element.
  • the spring slats are thus captively connected to the suspension element in the transverse direction.
  • the cross-sectional geometry of the suspension element guide does not have to correspond to the cross-sectional geometry of the suspension element. Both can be different, even though in many cases the cross-sectional geometry of the suspension element guide will correspond to that of the suspension element.
  • the at least one between the two Spring slats located spring slats deflect and pulls in this course by the associated increase in distance to the adjacent spring slats, if present, and to the spring slats or the support means to the extent of deflection.
  • the flexibility of the suspension means easily deviates from its unloaded, typically horizontal course with different deflection depths of the flexible slats. Due to the elasticity of the support means, no additional restoring means are required in principle in order to bring the support means back into their unloaded position after a spring deflection process and thereby return the trough in the lying surface caused by the load to its original position.
  • Such a spring base can be produced with simple means.
  • the support means which are typically designed as flexible rods with elastic properties in the transverse direction, preferably fiber-reinforced plastic rods, carbon fibers preferably being used as the fiber, although rods made of other materials, such as spring steel, can be used.
  • Fibre-reinforced plastic rods are preferred as load-bearing means due to their flexibility, even when the forces applied are low, and their typically smooth outer surface.
  • rods are preferably used in which the fibers follow the longitudinal extension of the rod.
  • such a rod may also include a fibrous structure in which the fibers are interwoven or otherwise engaged.
  • the spring slats can be drilled through in the transverse direction as support means guides.
  • adjacent spring slats have aligned bores as suspension element guides.
  • Another advantage of this slat base lies in this simple installation. This advantage consists in the fact that the flexibility (the required bending moment) influences the deflection behavior of this at least one spring slat that is not supported on the spar side and is held by the adjacent bearing spring slats can be.
  • the deflection behavior is harder than when using a more flexible suspension element.
  • the manufacturer can, for example, provide several suspension elements, each with a different bending moment. Exchanging an already mounted suspension element is easily possible due to the tensile strength, which also requires compressive rigidity, and can be done by anyone. Such a suspension element can thus be easily pushed out of the suspension element guides. In this way, the suspension element can be pressed out of the outer edge of a spring-loaded slat at least to such an extent that it can be gripped by the protruding section and then pulled out as a whole. It is not necessary to dismantle the female slats from the slat holders.
  • suspension element guides are designed as bores that reach through the spring slats, no additional elements are required in order to obtain the desired deflection comfort.
  • suspension means Since the suspension means is subjected to tensile stress when a spring slat held between two suspension spring slats deflects, the reliability of such a suspension means does not depend on elasticity and therefore proves to be far more durable, with no changes in properties.
  • Such a suspension element can have a circular cross section. It goes without saying that other cross-sectional geometries are also possible. Even if a rod is mentioned as the support means in the embodiment described above, it is not excluded that a tube can also be used as the support means, provided it has the desired flexibility.
  • the support means connecting the spring slats to one another in the region of their ends transversely to their longitudinal extent can be somewhat greater in length have than determined by the distance between the side faces of the bearing spring slats pointing away from one another.
  • the suspension element protrudes somewhat on the two side faces of the suspension spring slats that point away from one another.
  • Projecting or protruding from the sides of the spring-loaded slats pointing away from one another can be 1 to 5 cm, for example. This usually allows a sufficient material reserve.
  • an end cap is to be placed on the end of the suspension element as a stop, this must be taken into account with regard to the length of the section of the suspension element protruding from the suspension spring strip. A length of about 1 cm is considered sufficient for fitting an end cap forming a stop.
  • the suspension element has a deduction on at least one end, but preferably on both ends. Even if movements of the suspension element in a direction transverse to the longitudinal extent of the spring slats are generally not to be expected, such stops ensure that the suspension element remains in its intended position and does not move out of the suspension element guide of a suspension spring slat as a result of various deflection processes.
  • a stop can be provided, for example, by end caps, as already outlined above.
  • a stop element engaging in the suspension element guide of these suspension spring slats is connected to the end face of the suspension element.
  • this can be a screw that engages in the end face of the suspension element, the head of which represents the stop.
  • the spring-loaded slats have blind holes on their mutually facing narrow sides, into which the ends of the suspension element engage.
  • the support means or means are shorter than the distance between the two sides of the outer support spring slats that point away from one another.
  • these can also have guide elements, for example sleeves, as support means guides. This will typically be arranged on the underside of the spring strips. Instead of such a sleeve, it is also possible to mount one or two spaced-apart eyelets on the underside of such a spring strip, through which the suspension element is passed.
  • smooth displaceability of the suspension element(s) in the suspension element guides is provided in that the clear diameter of the suspension element guides is larger by a sufficient amount than the diameter of the suspension element.
  • Suspension means with a circular cross-section geometry are particularly smooth-running.
  • suspension element(s) Due to the high-tensile character of the suspension element(s), several spring slats that are not supported on the spar side can be arranged between two suspension spring slats, depending on the length of the area of the lower spring system that is softer in terms of its deflection characteristics, for example in the shoulder area or in the hip area.
  • each end area of such a spring slat group comprising two support spring slats and at least one spring slat arranged between them and not supported on the spar side can have several support element guides adjacent to one another on each end area.
  • the deflection characteristic of the flexible slats that are not supported on the spar side can be set up not only by using different suspension means with regard to their bending behavior, but also by the number of suspension means.
  • a suspension means provided for soft deflection can be preassembled at the factory.
  • the spring slats belonging to this group are arranged in alignment with one another in the unloaded position with regard to their support element guides. If a harder deflection behavior is desired, simply add an additional one Push the suspension elements into the suspension element guides of this spring slat group.
  • spacer means are arranged between adjacent spring slats of such a spring slat group, by means of which it is ensured that the spacing of the spring slats from one another remains constant.
  • These spacers can be sleeves or sleeve-like bodies, for example, through which the suspension element is guided. These spacers are supported with their end faces on the areas of the spring slats that enclose the openings of the suspension element guide.

  • the spring base 2 comprises a frame 4, of which the figure shows a longitudinal beam 5 and a transverse beam 6, the latter in section.
  • a plurality of spring strips 7 are arranged, which span the base of the frame 4 in the transverse direction.
  • 7 spring elements 8 are connected to the slats, on the top of which the mattress 3 rests.
  • the spring strips 7 are connected to spring strip holders 9 on the two longitudinal bars 5 lying opposite one another.
  • the slats 7 are made of wood.
  • the spring base 2 has a spring slat group 10 located in the shoulder area of the slatted frame, which is delimited by two supporting spring slats 11, 11.1 in the direction of the longitudinal extent of the bed 1.
  • the support spring slats 11, 11.1 are basically constructed like the other spring slats 7 of the slat base 2 and are also connected in the same way by means of spring slat holders 9 to the two longitudinal bars 5 of the frame 4.
  • These spring strips are referred to as support spring strips 11, 11.1, since in the exemplary embodiment shown they carry two spring strips 12, 12.1, which in turn are not connected to the longitudinal beams 5.
  • These slats 12, 12.1 are also equipped with spring elements 8 that correspond to those of the slats 7.
  • figure 2 shows the spring strip group 10 in a standalone representation.
  • the slats 12, 12.1 not held on the spar side are connected to the two external support spring slats 11, 11.1 by two flexible rods 14 as support means.
  • the flexible rods 14 are connected to the respective spring strips 11, 11.1, 12, 12.1 in the end section relative to their longitudinal extent. Because of the perspective, only one of the two flexible rods 14 can be seen.
  • the flexible rod 14 serving as a support means has high tensile strength and penetrates through each spring slat 11, 11.1, 12, 12.1 in a bore that crosses it in the direction of the longitudinal extension of the spring base 2.
  • the diameter of the bores is designed with sufficient play in relation to the diameter of the flexible rod 14 so that it can be displaced longitudinally in these bores without any significant resistance.
  • the spring slat bores represent suspension element guides.
  • the bores for the flexible rods 14 of the spring slats 11, 12, 11.1, 12.1 are aligned with unloaded spring base 2 with each other.
  • the flexible rod 14 is a fiber-reinforced plastic rod with carbon fibers as fibers.
  • the fibers extend in the longitudinal extent of the rod 14.
  • an epoxy resin for example a bisphenol A epoxy resin, has been used as the binder.
  • the flexible rods 14 have a fiber content of approximately 63% by volume.
  • the flexible rod 14 has a smooth outer surface, which supports its smooth displaceability or its sliding within the bores in the spring slats 11, 12, 11.1, 12.1 that serve as support means guides.
  • the diameter of the flexible rod 14 of this embodiment is about 4mm.
  • the spring slat bores serving as support means guides in this exemplary embodiment have a diameter of approximately 6 mm.
  • the material properties of the flexible rod ensure its tensile strength with a maximum elongation of 1 to 2% and sufficient flexibility in the direction transverse to its longitudinal extension.
  • the representation of the spring strip group 10 in the figure 2 makes it clear that the two spring strips 12, 12.1 located between the support spring strips 11, 11.1 are held solely by the flexible rods 14.
  • a deflection behavior of the spring slats 12, 12.1 is therefore dependent on the flexibility of the rods 14, that is to say the force that must be applied in order to be able to bend the rod 14 in the transverse direction to its longitudinal extent. Since the slats 12, 12.1 are not supported on the spar side, they form a particularly soft zone in the slat base 2.
  • the flexible rods 14 have a length that is greater than the distance between the side faces of the two spring slats 11, 11.1 that point away from one another.
  • the flexible rods 14 each have an end section 15, 15.1 that protrudes from each support spring strip 11, 11.1.

  • the spring slats 12, 12.1 located between the support spring slats 11, 11.1 of the spring slat group 10 and carried by them react particularly flexibly (softly).
  • the deflection situation of the spring strip group 10 in the in figure 3 The load shown is in an isolated representation of the spring strip group 10 in figure 4 shown.
  • the support spring strips 11, 11.1 move in the direction of one another about a virtual pivot axis which runs perpendicular to the plane of the longitudinal beam 5.
  • the longitudinal displaceability of the flexible rods in the spring slat bores as support means guides is necessary so that this vertical movement of the spring slats 12, 12.1 can take place.
  • This adjustment of the spring strips 12, 12.1 takes place against the restoring force of the flexible rods 14. It is therefore necessary to overcome a certain bending moment in the flexible rods 14 so that the in figure 4 deflection situation shown can occur.
  • the bending moment required for the adjustment of the flexible rods 14 is to the expected load by a person lying on the mattress 3, for example in the figure 3 lateral position shown, adjusted.
  • the deflection behavior of the spring slat group 10 and in particular its spring slats 12, 12.1 is used by the bending moment of the rods required for an adjustment in the transverse direction.
  • the design of the spring slat holder 9 of the support spring slats 11, 11.1 with regard to their in figure 4 recognizable pivotability also influences the deflection behavior of the spring slats of the spring slat group 10.
