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 areas of application. They are primarily used in the production of mattresses or furniture upholstery.
- the US 2007/0130883 A1 discloses a method and a device for producing pocket spring cores. In a strand with pockets for springs, you can select whether a spring with a thicker or thinner wire diameter is inserted, so that different spring behavior is generated depending on the spring inserted into a pocket.
- US 2017 / 035211 A1 discloses a mattress with two spring cores, which are held in a frame and interlocked into one another on the side facing each other by individual springs.
- the spring cores are each removable.
- the spring core with an upper and lower circumferential edge reinforcement, which is made of a round or flat material, preferably made of metal.
- Such a spring core is, for example, from WO 96/35 355 A1 known.
- this spring core cannot be rolled up and unrolled, so it does not meet the requirements for optimized production.
- the spring cores In order to complete the end product, mattress or upholstered part, the spring cores usually have to be transported from the place of manufacture to the mattress production site, whereby the respective production sites can be spatially very far apart.
- spring strands are used whose springs are harder than those of the springs of neighboring spring strands. This is achieved through various selection criteria, for example through different wire diameters or by changing the number of turns. A selection of different material properties can also cause a corresponding change in spring behavior, as can a waist of the individual springs.
- spring strands When producing spring strands by machine, spring strands can only ever be equipped with the same springs.
- a previously described frame has been used which completely encloses the spring core.
- the spring strands at least some of which are composed of, so to speak, individual spring strands that differ in their suspension behavior, extend in the longitudinal direction of a rectangular, elongated spring core. This means that the partial spring strands of a spring strand add up to the total length of the spring core.
- the invention is based on the object of designing a pocket spring core of the generic type and a method for producing such a pocket spring core in such a way that machine-automatic production of the spring core as a whole is possible and cost optimization is achieved.
- the invention now makes it possible to create any different zoning of the spring core by mechanically producing, depending on the requirement, either spring strands 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 in this way, that spring strands result in areas with different suspension behavior.
- the individual springs of a partial spring strand have the same spring characteristics.
- this spring characteristic can be influenced, for example, by the material selection of the spring wire, the wire diameter and the shape of the spring, the latter for example as a waisted, cylindrical or barrel-shaped design.
- the new pocket spring core offers clear advantages over one based on the state of the art, both in terms of manufacturing costs as well as in terms of handling and freedom of design.
- the production of the new pocket spring core can be carried out fully automatically, i.e. by machine, which concerns both the production of the partial spring strands, their assembly to form a complete pocket spring core, as well as the connection of adjacent pocketed springs with different spring characteristics.
- pocket spring cores are possible, depending on the needs of the future user. This includes consideration of the suspension behavior of various zones. This means, for example, that one-sided, multi-sided or all-round edge reinforcement is easily possible with correspondingly harder spring characteristics. Likewise, preferred zones within the lying surface can be individually adjusted during the production of the pocket spring core and are essentially cost-neutral due to the automated production.
- the further processing of the pocket spring core into a mattress or a cushion that can be used for other purposes is also unproblematic, especially with regard to the transport from the production site of the pocket spring core to the further processing company. This is mainly because of the pocket spring core It can be rolled up and therefore only requires a small amount of transport space, which also contributes to cost optimization.
- the invention according to which partial spring strands of adjacent spring strands are of different lengths and these adjacent partial spring strands are connected to one another, creates a toothing which results in a firm connection of all spring strands, although the partial spring strands with different suspension behavior of a spring strand are not connected to one another can be connected, at least not mechanically, as is possible when connecting several spring strands next to one another.
- the partial spring strands lying parallel to one another can be connected by gluing or welding, which is done by machine in the same way as the partial spring strands are manufactured.
- the method for the mechanical production of a pocket spring core is, according to the invention, designed in such a way that at least some of the spring strands are first produced as partial spring strands with different suspension behavior in different lengths, then adjacent partial spring strands are connected to one another, with partial spring strands with different spring characteristics overlap with their free end, so to speak, and are also connected to each other in this overlap area.
- a section is shown in the area of a corner of a pocket spring core, with a plurality of pocketed springs 4, 5, several of which, arranged in a row one behind the other, form a spring strand 1, the springs 4, 5 each being in a flexible, preferably Insert a pocket made of textile material. These pockets are connected to one another by webs 6.
- the individual spring strands 1 lying parallel to one another are each formed by partial spring strands 2, 3, the suspension behavior of which is different, which is illustrated in the figures by different line widths of the pocketed springs 4, 5.
- the partial spring strands 2, 3 are of different lengths, in the examples each by a spring 4, 5.
- the spring strand 1 which forms an outer edge of the lying surface and is lower in the plane of the drawing, is continuously equipped with the same springs 5 and thus forms an edge reinforcement, as does the row of springs 5 lying next to one another at an angle to it, which consists of the last spring in each case 5 of the spring strands 1 lying next to each other, whereby this edge reinforcement can be circumferential.
- the springs 5 shown in the figures with a larger line width are harder in their suspension characteristics than the springs 4 shown with a smaller line width.
- the arrangement of the partial spring strands 2, 3, depending on the desired suspension behavior of corresponding areas of the spring core, can be selected arbitrarily and only depends on the customer's wishes.
