Definitions

  • the present invention relates to a spring system for a mattress or under mattress with at least one spring element with two spring-elastically movable relative to each other parts, such as cover plate and bottom plate, and means for adjusting the spring rate of the spring system.
  • Such spring systems are known in many ways. They are used, for example, as individual support elements in sub-mattresses instead of conventional slats to accurately support a mattress. Preferably, the individual support elements are provided only in partial areas of the lower mattress. Such spring systems can also be used in mattresses themselves, namely in so-called spring mattresses.
  • the invention has for its object to simplify the adjustment of the spring rate of such spring systems and improve.
  • This object is achieved in that is supported on one of the two parts or a connected thereto element such as support bar for the spring element, an elastically deformable element with adjustable spring stiffness on which a connected to the other part actuator when moving against each other of the two parts and attacks it deforms.
  • the spring stiffness of the deformation element is manually adjustable. This is on the one hand cost in the production and handling and avoids the other repair-prone electrical, pneumatic or hydraulic systems.
  • the deformation element may be formed in particular as an elastic band.
  • An elastic band has the advantage that its spring hardness is adjustable by simply stretching the elastic band. As a result, the elastic band can be adjusted for example by winding on a drum in its hardness.
  • an elastic band is inexpensive, space-saving and can adapt well to local conditions.
  • Another way of adjusting an elastic band is to guide it through a sleeve element with locking device. After appropriate stretching of the elastic band prevents the locking device shortening the elastic, so that it remains taut and has the desired spring hardness.
  • the locking device can in particular be a bolt which is supported on the elastic band under spring load, as is known, for example, from the clothing industry for the adjustment of cords.
  • the handling of such a system is particularly simple.
  • the actuating element for actuating the deformable element can be designed in particular as a plunger. This training is manufacturing technology simple yet reliable.
  • actuating element is formed as a lever, which is tilted upon compression of the spring element and actuates the deformation element. This is also advantageous in certain applications.
  • the spring system according to the invention can be advantageously used in a spring arrangement by several spring systems according to the invention are arranged side by side.
  • the spring systems can be arranged in particular in rows and / or columns. This results in a flat elastic support, for example, as a mattress or part of a mattress or as a mattress itself.
  • a plurality of juxtaposed spring systems have a common deformation element.
  • an elastic band can overlap a complete column or a complete row. This is particularly cost-effective in the production also advantageous in the application, since stretching of an elastic band spring stiffness of all associated spring systems can be changed.
  • a spring arrangement is provided with a plurality of spring systems arranged in rows and / or columns with adjustable spring hardness, in which a plurality of spring systems detecting Bowden cable is provided for adjusting the spring rate.
  • the adjustment by means of a Bowden cable has the advantage that it can adapt flexibly. For example, in the adjustment of spring systems arranged on spring strips, the Bowden cable can bend together with the spring bar. In addition, a Bowden cable is easy to handle.
  • each spring system 1 comprises a spring element 2 with a cover plate 3 and a bottom plate 4. Between cover plate 3 and bottom plate 4 are arranged once outwardly angled spring struts 5, which deform elastically upon application of a force according to arrow I on the cover plate 3, as at the middle of the three elements in Fig. 1 is shown.
  • the spring elements 2 are each arranged with their bottom plate 4 on a support bar 6. Laterally to the bar 6, an elastic band 7 is provided, which is passed between each two spring elements 2 through eyelets 8, which are mounted laterally on the bar 6. With the cover plate 3 of the spring element 2 in each case a plunger 9 is connected, which is after extends down to the elastic 7.
  • the plunger 9 is arranged so that the elastic band 7 is bent in compression of the spring element 2 according to arrow I downwards, as shown in the middle spring element 2 in Fig. 1.
  • the spring elasticity of the elastic band 7 adds up to the spring hardness of the spring element 2 added. Accordingly, the spring stiffness of the spring system 1 can be changed by tensioning the elastic band 7, and for all adjacent spring systems 1 evenly.
  • Another possibility is to pull the elastic band 7 through a sleeve member and lock in the sleeve member by a locking device.
  • the spring elements 2 of the spring systems 1 are substantially the same design as the spring elements of Fig. 1. They only have additional supports 10, which are connected to the bottom plate 4 and project upwards. Between these supports 10, the elastic band 7 is now stretched, wherein each spring element 2 has an elastic band 7. The elastic band 7 is in turn bent downward by the plunger 9 when the spring element 2 is compressed by the action of a force in the direction of arrow I. Here, too, results in a changed spring hardness of the spring system 1, which is variable by tensioning the elastic band 7.
  • the plunger 9 may also have a distance from the elastic band 7, so that the contribution of the elastic band 7 to the spring rate only occurs after a certain distance. This results in a two-stage spring characteristic of the spring system. 1
  • the illustrated spring systems 1 can be arranged in rows and / or columns to form a resilient support surface. In particular, they may be part of a mattress on which a mattress is placed. But they can also be used as a spring inside a mattress.
  • the internal spring systems can be adjusted by tightening the elastic band 7 easily from the outside in the spring rate.
  • the adjustment could be made via a Bowden cable, so that an adjustment of internal spring systems from the outside would be possible here as well.
  • Such a Bowden cable can also be advantageously used in conjunction with other adjustable spring systems. If these are arranged on spring strips, the Bowden cable has the advantage that it flexes flexibly with the spring strip.
  • spring systems 1 are used, as shown in Fig. 2 and described above.
  • the spring systems 1 are arranged between two foam layers 11 and 12. You can also be arranged in pockets. The operation is according to the use in connection with the support slats 6 of Fig. 2nd
