Definitions

  • the invention relates to a spring strip for a seat oroutheasternellefederung comprising at least two superimposed in the compression direction single spring strips, wherein the at least two individual spring strips are connected at their longitudinal axial ends acting in the longitudinal direction rigidly together. Furthermore, the invention relates to a spring base with at least one such spring bar.
  • Mattress pads serve to support a mattress and to increase lying comfort, compared to lying on a mattress without such spring support.
  • Matratzenunterfederonne are known in different configurations. Matratzenunterfederonne that adapt in a special way to the lying position of a lying on the mattress top person have a variety of individual and independently responsive spring elements.
  • Lower cost mattress supports have a frame formed of two longitudinal beams and the longitudinal beams end connecting crossbars, which carries a plurality of the longitudinal bars connecting spring strips. The transverse to the longitudinal extent extending spring strips such mattress suspension are yielding. The ends of the spring strips are usually connected with the interposition of executed by type of caps Kunststoffan gleichtücken to the longitudinal bars.
  • Such a mattress suspension is also addressed as a slatted frame.
  • the spring strips of such a mattress suspension are in many cases those made of wood. Are used at this point, other materials, such as fiber-reinforced plastics or the like. Due to the thickness and / or the width of the spring strips the jounce characteristic of the same is specified. Also known are female connectors, which consist of two individual spring strips, of which only the upper spring bar is connected at their ends to a spar of Matratzenunterfederung. The lower spring bar is connected over the longitudinal extension of the slats sliding slide to the upper spring bar. Are these Einfederhärteeinstellschieber in the central position of these two spring strips, the entire compression work is taken over by the upper spring bar.
  • EP 0 397 978 A1 discloses a spring bar for a slatted frame.
  • This known spring bar is in one piece.
  • the spring bar is made of several glued together and pressed veneer wood layers and an arranged between the veneer wood layers and glued with these elastic layer.
  • the elastic layer thins out toward the longitudinal axial ends of the veneer layers, so that they are glued together in the two end regions without the interposition of the elastic layer.
  • EP 2 105 068 A1 describes a spring bar made of plastic or plastic mixture. This known spring bar is curved against the compression direction over its span across. On the underside of the spring bar, a longitudinal web is connected, which is supported at the ends and by means of intermediate webs on the underside of the spring bar. The longitudinal bar runs straight and does not extend to the end of the actual spring bar.
  • the invention is therefore based on the object to propose a spring bar through which, without requiring additional elements, a sleeping position, in particular a side sleep position by forming a correspondingly limited to the lying area videkuhle is stabilized.
  • the spring strip comprises at least two single spring strips, which are arranged in the compression direction at a distance from each other. In the area of their ends, the single spring strips are rigidly connected. This rigid connection acts between the single spring strips at least in the longitudinal extension of the same. Is achieved by this connection that the single spring strips at a deflection of the spring bar can not move in longitudinal axial extension against each other. Because of the convex curvature of the single spring strips in the unloaded state, an individual spring strip located above each strives towards the underlying single spring strip to execute a compensating movement in longitudinal extension relative to the single spring strip located thereunder as a result of shortening by spring deflection.
  • Such a compensating movement is prevented in this spring bar, however, due to the force acting in the longitudinal extent of the single spring strips rigid connection in the ends.
  • the forcibly self-adjusting movement then leads to buckling or buckling of the upper single spring bar.
  • Such a bulge is dependent on the compression work done and also on the position at which the compression takes place with respect to the longitudinal extension of the spring bar. In any case, at least one such bulge forms between the end portion of the spring bar and the position of the deflection.
  • a sleeping position on such a slats comprehensive spring base is formed either on both sides to the position of the person lying on it by a respective bulge or only on one side by a bulge and on the other side by the completion of the lower spring.
  • a lying on such a spring bar recumbent couch has, as a rule, a smaller span than this would form in conventional spring strips. For this reason, when using this spring strips in a mattress suspension a sleeping position is much better fixed than when using conventional spring strips. Especially positive makes this effect when, when using such spring strips in a Matratzenunterfederung a person has taken a side sleeping position outside the middle of the mattress.
  • the top single spring strut endeavors to perform a directed in the longitudinal direction of the same compensating movement relative to the or below the single spring strips only in that section that is not burdened by the person. The bulge forming in the uppermost single spring strip is then particularly concise.
  • the couch is adjusted by forming the one or both of the above-described protrusions to a particular extent to the contour of a person lying on the mattress when using the same in a mattress suspension.
  • a so-called "roll-out effect" has been encountered.
  • this can be produced not only without additional elements or devices but also cost.
  • a mounting of such a spring bar over conventional spring strips is not difficult.
  • An assembly is carried out in the same way by inserting the opposite ends anchored in grooves in the spar or in corresponding connection caps, which are connected to the spars of a Unterfederungsrahmens.
  • the spacing of the individual spring strips can be the same across their span. There is also the possibility that the distance between the uppermost single spring strip and the single spring strip located below it in the compression direction increases from the regions of the end connections in the direction of the center. The result is that then the top single spring bar has a greater curvature relative to the underlying. The associated greater length of the upper single spring bar results in a deflection process for the formation amount greater compensating movement result, which in turn leads to a stronger bulge. As a result, a sleeping position is much better fixed than reclining, which can be formed by using conventional spring strips.
  • the jounce comfort in such a spring bar can be set up by the number and the design of the individual spring strips involved in such a spring bar.
  • the single spring strips of such a spring strip can be made of the same or a different material.
  • the individual spring strips may be formed differently in terms of their dimensioning with respect to their material thickness and / or width.
  • spacers which are inserted between the adjacent end sections of adjacent individual spring strips are used according to an embodiment.
  • the above-described rigid connection can be achieved, for example, by an adhesive connection of the parts involved in the creation of the rigid end connection.
  • an end connection thorough fastener and / or these enclosing sleeves can be used, as well as mechanically made by cutting of solid wood or one-piece plywood, as long as it is ensured that the individual spring strips in the longitudinal extension thereof do not move in the region of their ends against each other can.
  • a further connection point is provided, in which the single spring strips held at a distance from each other and acting in the longitudinal direction are rigidly connected together.
  • Such spring strips are also suitable for dividing the lying area, if this is intended for two people.
  • Such an additional connection point can also be useful within a lying surface area for a person, for example to achieve a special Buckling characteristic in the pelvic / hip area of a mattress suspension. It is understood that in case of slats with a larger span more than one additional connection point can be provided.
  • such a spring bar is slightly harder than one without additional, typically central additional connection point. Also, one can choose such a configuration, if the one or both should be formed less strong as a result of deflection forming bulges, compared with a previously described spring bar without the other, typically central, connection point.
  • spring strips are basically suitable for implementation in any spring suspension, be it for a sitting or a reclining furniture.
  • spring strips are particularly suitable in connection with an insert in a Matratzenunterfederung (slatted frame). In such a case, it is particularly useful to provide these slats due to their special contour adjustment for the shoulder and / or pelvic area.
  • a mattress suspension 1 comprises a frame 2, which is constructed in the illustrated embodiment of two longitudinal bars 3, 3.1 and two the longitudinal bars 3, 3.1 connecting cross bars 4, 4.1.
  • the longitudinal bars 3, 3.1 enclose a lower suspension area. This is covered by spring strips. These are connected in a conventional manner by means of spring strip caps 5, in which engage the spring strips with their ends to the longitudinal members 3, 3.1.
  • the mattress suspension 1 has several special spring strips 6, which are described below. The remaining slats are conventional slats.
  • the spring bar 6 In the side view of FIG. 2 is such a spring bar 6 with respect to their structure recognizable.

  • the taper is introduced into the pointing to the pressure load side top of the female connector 6 by a material reduction.
  • the taper of the pressure shadow side of the spring bar 6 is provided. The transition from the pressure side of the spring strip 6 in the adjacent groin cap then takes place without a groove in which the mattress base or a reference could jam during the process of compression or rebound.

  • the material thickness of the spacers 8, 8.1 in the illustrated embodiment corresponds to those of the Einzelelfederancen 7, 7.1, 7.2.
  • the distance between the individual spring strips 7, 7.1, 7.2 provided by the spacers 8, 8.1 corresponds to the material thickness of such.
  • the material thickness of the spacers, which determine the spacing of the individual spring strips from one another may also be different from the material thickness of the individual spring strips and may also be provided differently from each other. Different distances lead to a different design of a couch, so that the distance of the individual spring strips is provided from each other depending on the desired training a couch.
  • FIG. 4 shows the behavior of the spring strip 6 at a central load by a person in back sleep position.
  • a mattress located on the mattress suspension 1 mattress. Due to the central load of the spring bar 6 forms a couch 11 at its center. Due to the above-described embodiment of the spring bar 6, the couch is limited to the actual width of the body parts, which act on the spring bar 6.
  • the forming Medkuhle 11 thus does not extend from the engaging in the spring strip caps ends to the middle, but as a result of the above-described concept of spacing the Einzelfederancen 7, 7.1, 7.2 from each other, but is limited to the or those sections, in contrast to prior art which are specifically claimed by the use of the person on the mattress spring 1.
