Definitions

  • the invention relates to a pocket spring core according to the preamble of claim 1.
  • pocket spring cores form an essential element, for example, a mattress, for their production, the pocket spring core is covered with various materials.
  • an edge reinforcement which is formed by a circumferential metal frame, which is connected in the edge region of at least one formed lying surface by clamping with the outer spring pockets.
  • pocket springs are mass-produced as mass-produced products, this circumstance is of particular importance and counteracts the constant demand for cost optimization.
  • a pocket spring core with circumferential reinforcing frames, which are fastened to the two broad sides of the pocket spring core, each forming a lying surface, is in the WO 96/35355 A1 disclosed.
  • a pocket spring core is known in which the spring strands are aligned transversely to the longitudinal extent, wherein between the individual spring strands stiff strips of material are arranged through which a hinge effect is achieved in order to use such a pocket spring core, especially in slatted frames with adjustable foot and head part.
  • the invention has for its object to further develop a pocket spring of the generic type so that structurally simple means necessary for further processing of the pocket spring core dimensional stability can be produced without significantly affecting the suspension behavior, while cost-effective production.
  • a modified in this sense pocket spring core can be initially without any significant additional cost compared to such produce without reinforcing strips, which not only the reinforcing strips can be provided even with little effort, but also their attachment to the spring strands or.
  • the reinforcing strips are firmly bonded thereto, for which purpose, in particular, gluing is suitable.
  • the spring strands are, as mentioned, glued together, which is done on suitable production equipment.
  • the attachment of the reinforcing strips by gluing can be integrated into this production process, so that in this respect the production of the pocket spring core is almost cost-neutral.
  • the reinforcing strips can also be connected by positive locking, in particular by brackets on the spring strand.
  • the reinforcing strips which preferably extend over the entire length of the corresponding spring strand, are positioned at a distance from the outside between two adjacent spring strands, wherein an optimization of the desired dimensional stability consists in arranging two reinforcing strips which are spaced apart, preferably equidistant from the adjacent one outer edge.
  • the reinforcing strips are mounted approximately halfway up the springs. However, it is also conceivable to fasten more than one reinforcing strip to the corresponding spring strand.
  • two reinforcing strips are arranged at a distance from each other on the opposite outer spring strands, and preferably in the respective edge regions assigned to the lying surfaces and these reinforcing strips by connecting to one another over the entire length of the reinforcing strip extending flexible band.
  • the width of the band is chosen so that it is tightened in a relaxed position of the springs, so that there is a smooth surface.
  • This band covers the adjacent spring strand almost completely and thus forms a contact surface for a fabric, with which the spring core is wrapped to produce a mattress.
  • strips are mainly used primarily made of foam, as it is also used to cover the lying surfaces forming broadsides. These, so to speak, liners are then wrapped by the mattress cover fabric.
  • the two reinforcing strips are held at the two longitudinal edges of the band, for which purpose these longitudinal edges are folded over and formed to form a receiving pocket, so that the reinforcing strips are enveloped by the band.
  • the band may be made of any suitable flexible material.
  • textile, fleece or plastic film may be mentioned here.
  • the material of the band is preferably made of the same material in which the springs are dipped, especially when the attachment is made materially.
  • Each reinforcing strip in particular when a single is attached to a spring strand, has a shell made of said material, so that a material connection by gluing with the bag material is readily possible.
  • the buckling rigidity of the reinforcing strip which is largely in operation according to the invention, is preferably achieved by a metal core which is enclosed by the casing and which is formed by a correspondingly dimensioned wire.
  • the cohesive connection can be made by said bonding, but also by other suitable methods, for example by welding, such as thermal or ultrasonic welding.
  • a spring core which consists of a plurality of juxtaposed and interconnected spring strands 1, each spring strand 1 is formed of a plurality of springs 5, which are arranged in a row one behind the other and each in a flexible, preferably textile material existing bag 2 are stored. Between two pockets 2 of a spring strand 1 is made by a material consisting of the pocket material web 3, a distance that results in a certain, the further processing of the pocket spring core aggravating instability.
  • a spring core is rectangular in plan, wherein the spring strands 1 define the longitudinal extent, while the width of the spring core results from the abutting single springs 5. In the in the FIG.
  • each reinforcing strip 4 is connected in a materially bonded manner to adjacent spring strands 1, each reinforcing strip 4, according to the invention, being largely kink-resistant in function.
  • each reinforcing strip 4 extends over almost the entire length of the spring core and is preferably attached to each adjacent pocket 2.
  • the reinforcing strips 4 of the pocket spring core is stabilized in its shape so that easy handling for further processing is possible.
  • Exemplary are in the FIG. 1 provided inside the pocket spring core two spaced apart reinforcing strips 4, which are preferably positioned at the same distance from the outer edge of the pocket spring core.
  • reinforcing strips 4 can also be arranged on the opposite outer longitudinal sides. In the FIG. 2 is such a reinforcing strip 4 to recognize as a detail, for which the pocket spring core is shown partially cut.
  • the reinforcing strip 4 consists of a sheath 6, formed of the same material as the pockets 2, wherein in this case 6 in the manner of a piping a metal wire 7 is included. While the sheath 6 virtually forms a connecting element to the pockets 2, the metal wire 7 causes the buckling resistance. It is also conceivable to use a wooden soul.
  • the reinforcing strip 4 is attached halfway up the pockets 2 to the spring strands 1 and thus in a neutral zone, so that, independent of which side of the spring core is used as a lying surface, the suspension behavior of the springs 5 is not affected ,
  • the reinforcing strip can be connected at any height between two end rings bounding the respective spring 5.
  • two reinforcing strips are arranged in the form of the described metal wires 7, which are positioned in the upper and lower edge region of the spring strand 1 on the outside of an outer spring strand 1 delimiting the spring core.
  • These metal wires 7 are enveloped by the edge regions of a band 8 of a flexible material which connects the two reinforcing strips 4 and which largely covers the outside of the spring strand 1, wherein of course the outer spring strand 1 is configured on the opposite side in the same manner ,
  • the band 8 is in the non-use position of the spring core, ie relaxed springs, tightened, that is, the width of the band 8 is adapted to the dimension of the springs 5.
  • the band 8 can otherwise be glued, welded or clamped partially or in the entire contact area with the bellies of the springs 5 with the pockets 2, so that a solid composite is formed.
