Definitions
- the invention relates to a pocket spring core according to the preamble of claim 1 and a method for producing a pocket spring core.
- Such spring cores are used in many applications. Primarily they are used in the production of mattresses or furniture upholstery.
- the spring core in order to achieve a sufficient edge stability, which is desired when the pad or the mattress is partially used as a seat, it is known to provide the spring core with an upper and lower circumferential edge reinforcement, made of a round or flat material , preferably of metal.
- Such a spring core is known for example from WO 96/35 355 A1.
- this innerspring can not be rolled up and unrolled, so that it does not meet the requirements for optimized production.
- the respective production facilities can be spatially very far apart.
- spring strands In order to achieve a different in their suspension behavior zoning, even for the named edge reinforcement, without a circumferential metal frame, find spring strands use whose springs are harder than the springs of adjacent spring strands. This is achieved by various selection criteria, for example by deviating wire diameters or by changes in the numbers of turns. Also, a selection of different material properties may justify a correspondingly changed spring behavior, as well as a sidecut of the individual springs. In the mechanical production of spring strands spring strands can always be equipped with the same springs.
- the spring strands In order to assemble spring strands with partially different springs to form a spring core, wherein, according to the genus, adjacent strands of spring are connected to each other, so far a prescribed frame is used, which encloses the innermost spring in its entirety.
- the spring strands of which at least a part are composed of quasi single spring strands, which differ in their suspension behavior, extend in the longitudinal direction of a rectangular elongated spring core. That is, the partial spring strands of a spring strand result in the sum of the total length of the spring core.
- the invention is based on the object, a pocket spring core of the generic type and a method for producing such a pocket spring core in such a way that a machine automatic production of the spring core is overall possible and cost optimization is achieved.
- a spring core with the features of claim 1 and by a method for producing the spring core.
- the invention now provides the possibility of creating arbitrarily different zonings of the spring core by mechanically, depending on the claim, either spring strands are made with the same springs or partial spring strands, each with different spring characteristics of the individual springs, which are then joined together in further process steps, that spring strands result with partially different suspension behavior.
- the individual springs of a partial spring strand are the same in their spring characteristic. In known manner, this spring characteristic can be influenced for example by the choice of material of the spring wire, the wire diameter and the spring shape, the latter, for example, as a waisted, cylindrical or tonnförmigen training.
- the manufacture of the new pocket spring core can be fully automatic, i. machine, which concerns both the production of the partial spring strands whose joining to a so far complete pocket spring core, as well as the interconnecting adjacent, in their spring characteristic differentisertaschter springs.
- pocket spring cores are possible, as needed by the future user. This includes the consideration of the suspension behavior of different zones. That is, for example, a one-sided, multi-sided or peripheral edge reinforcement is possible without any problems, given a correspondingly harder spring characteristic.
- preferred zones within the bed surface in the manufacture of the pocket spring core are individually adjustable and due to the automated production substantially cost neutral. Due to the omission of a circumferential metal frame, the further processing of the pocket spring core to a mattress or otherwise usable pad unproblematic, especially with regard to the transport of the manufacturing facility of the pocket spring core to the processing operation. This is mainly because the pocket spring core can be rolled up and thus requires only a small transport space, which, incidentally, also contributes to cost optimization.
- the invention according to the partial spring strands of adjacent spring strands are different lengths and these adjacent Operafedersträn- ge interconnected, a gearing done from which results in a solid composite of all spring strands, although the partial spring strands with different suspension behavior of a spring strand are not interconnected, at least not mechanically, as is possible in the connection of several juxtaposed spring strands.
- the connection of the parallel juxtaposed partial spring strands can be done by gluing or welding, which is also done by machine as the production of the partial spring strands.
- the method for machining a pocket spring core is, according to the invention, designed so that initially at least a part of the spring strands produced as partial spring strands with different suspension behavior in different lengths, then adjoining partial spring strands are interconnected, with partial spring strands overlap with their so-called free end with different spring characteristics and are also connected together in this overlap area. Further advantageous embodiments of the invention are characterized in the subclaims.
- Figure 1 is a schematic illustration of a detail of a pocket spring core according to the invention in a perspective view
- FIG. 2 is a schematic illustration of a detail of another embodiment of a pocket spring core according to the invention in a plan view.
- a detail in the region of a corner of a pocket spring core is shown, with a plurality oftienttaschten springs 4, 5, of which a plurality of successively arranged in a row form a spring strand 1, wherein the springs 4, 5 each in a flexible, preferably Cover bag made of textile material.
- These pockets are interconnected by webs 6.
- spring strands 1 which are arranged side by side and connected to each other, for example by gluing or by welding, bil- a lying surface, wherein the length of the spring strands 1 corresponds to the length of the rectangular lying surface ..
- the individual parallel spring strands 1 are each formed by partial spring strands 2, 3, whose
- the partial spring strands 2, 3 are of different lengths, in each case by a spring 4, 5.
- a shorter partial spring strand 3 is arranged between two longer partial spring strands 3, so that the partial spring strand 3 which completes the spring strand 1 protrudes between the two longer partial spring strands 3 and, like the short partial spring strand 3.
- Spring strand 3 is fixed with the longer part spring strands 3 lying on both sides in the region of a connection point 7. Incidentally, all juxtaposed spring strands 1 in the abdominal region of their individual springs 4, 5 or at their pockets are connected to each other.
- the spring strand 1 forming an outer edge of the lying surface, in the plane of the drawing is continuously equipped with identical springs 5 and thus forms an edge reinforcement, as well as the row of juxtaposed springs 5 running at an angle thereto which results from the respective last spring 5 of the juxtaposed spring strands 1, wherein this edge reinforcement can be circumferential.
