Definitions

  • the invention relates to a spring strip for a Matratzenunterfederung, which spring bar is designed as a double spring bar and an upper spring bar and a lower spring bar comprises, wherein the upper spring bar with the same force is more yielding than the lower spring bar and both spring bars held in the region of their ends at a vertical distance from each other are, which double spring strip has at least one arranged between the end portions thereof support, by which the upper spring bar is supported on the lower 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.
  • spring strips which are composed of several vertically overlapping spring strips. Typically, two such spring strips are used. This spring strips are held at the end with mattress frame side distance.
  • previously known such spring strip designs have a support by which the upper spring bar is supported on the lower spring bar.
  • Such spring strips are made for example FR 500 894 . DE 298 17 431 U1 as well as from the post-published EP 2 965 665 A1 known. In these previously known double or multi-spring bar arrangements, the multiple arrangement serves to obtain a progressive deflection characteristic.
  • the main focus in this prior art is the holding together of the vertically spaced spring strips.
  • the present invention seeks to propose a spring strip for a Matratzenunterfederung, which not only provides a high comfort, but also counteracts a formation of mattress side permanent recumbent and yet favors the formation of a particular sleep positions supporting couch.
  • These double spring strips have an upper spring strip and a lower spring strip.
  • the spring strip coupling acts in the direction of loading and thus in the direction of compression.
  • the upper spring bar is supported between its ends, preferably centrally with respect to the span of the double spring bar on the lower spring bar.
  • This support is arranged by a between the spring strips, provided as a supporting element support provided, which is held between the two spring strips.
  • the support element with regard to the deflection characteristic of this double spring strip, the span thereof is subdivided into two softer areas with respect to their spring deflection characteristics. These are located between the respective end of the double spring bar and the area of the support provided by the support element. This is true for an embodiment in which a single support element is provided between the upper spring bar and the lower spring bar. Quite possible is also an embodiment in which then can be arranged with correspondingly greater span of the two spring strips between these two or more support elements.
  • Such a division of the lying surface into individual lying areas serves the purpose that in the spring strip sections, in which the two spring strips are spaced apart, in the manner described above, a couch also already forms with a relatively lower weight acting thereon.
  • a lying area can be used for example for a lateral position.
  • the body of a person lying on such mattress suspension mattress extends over several lying areas and thus also via a spring strip support the lower spring bar is involved directly in the compression process. Accordingly, only a couch of lesser depth, but with a greater width, forms. This is the case for example in a supine position and in this desired.
  • the shoulder blades are already in a lying adjacent to the support lying area, so that even in a reserve, the upper spring bar resiliently responds to impressions of the scapula in the mattress or at least can respond.
  • a lateral position however, the formation of a much deeper couch is desired. This is possible if the person using the mattress suspension is positioned adjacent to a spring strip support in a lateral position. Then occurs the already described above effect that the upper spring bar contributes due to its softer compression properties in particular dimensions to the formation of narrower and deeper Montkuhle.
  • the amount of deflection of the upper spring bar without the involvement of the lower spring bar is defined by the distance between the two spring strips in such a lying area between two spring strip supports.
  • the support member for supporting the upper spring bar on the support forming the same takes place on a support surface thereof.
  • the support surface against which the underside of the upper spring strip abuts is convexly curved in the direction of the upper spring strip.
  • the support takes place over a certain longitudinal extent of the spring bar, and thus not alone in a line contact.
  • the upper spring bar relative to the support is movable, in the longitudinal direction of the spring bar. In this way, a balance of displacements during compression between the spring strips should be allowed.
  • the upper spring bar is also on unloaded spring bar on the support surface of the support. In one embodiment, it is provided that this system is provided with a certain bias.
  • the double spring strips each have an upper spring strip and a lower spring strip so that the spring strip doubling acts in the loading direction.
  • the upper spring bar is more yielding and thus springs already at a lower load, as the lower spring bar, for the deflection of a higher weight is needed.
  • both spring strips are arranged vertically spaced from each other and thus are held at a vertical distance from one another in the region of their ends.
  • the upper spring bar also serves the purpose of a force absorption by deflection.
  • the relevant compression work is done according to a preferred embodiment of the lower spring bar.
  • the upper spring bar primarily serves to form a couch, which then adjusts itself at a relatively low pressure acting on the mattress (weight).
  • An advantage of such a configuration is that the upper spring bar compliantly reacts even at low Aufliegewith on the mattress and thus is responsible for the formation of a Stanfordkuhle without a compression of the lower spring bar is necessary.
  • a couch at the top of the mattress is equally formed when a person of low weight lies on the matzo, as well as a person with a greater weight.
  • a couch not only independent of the weight lying on it person forms, but also regardless of the elasticity properties of the mattress, so: whether it is softer or harder.
  • the upper spring bar assumes such a double spring bar at least a share in the formation of a couch, so far as the mattress itself is less stressed. Due to the significantly longer duration elasticity of the upper spring bar, compared with that of the mattress, even a long-term permanent training of a couch in the mattress itself is avoided.
  • a support member is mainly a made of plastic part, as this can be produced inexpensively even with more complex geometry.
  • An embodiment is advantageous in which such a support element comprises two individual molded parts which are typically designed C-shaped. In a C-shaped design of these moldings, these are arranged with their open mold sides facing each other, preferably with a small distance from each other. These moldings are attached to the lower spring bar. The spacing of the upper ends of these molded parts from one another serves the purpose of providing a certain amount of additional flexibility, since the mutually facing end faces can move towards one another when the double spring strip is loaded in the direction of compression. In such an embodiment, it is expedient to connect the two mold parts with one another for easy handling with a flexible connecting member. Typically, this will use a film hinge, since this can be formed simultaneously with the production of the two moldings.
