Definitions

  • the present disclosure relates to a spring core having a plurality of helically wound springs.
  • the springs of such spring cores are normally made of wire and are known, for example, as Bonell springs or barrel springs.
  • the spring cores formed thereof have a superlinear, that is, uniform spring action.
  • the same degree of hardness exits at any point in time of the use of the spring core.
  • padding For this purpose, it has been attempted to achieve a certain softness by applying padding.
  • this application of padding to the mattress is not suitable for meeting the demands in the widest sense of the word, particularly because the elasticity of such padding is not comparable with a springiness.
  • the present disclosure relates to a spring core such that the comfort of resting on it is improved at the lowest possible manufacturing expenditures.
  • the present disclosure thus relates to a spring core including a plurality of helically wound springs, At least two of the plurality springs are shaped as or include a bulging at least at one of two end regions of each of the at least two springs in a direction of a longitudinal axis of the at least two springs.
  • projecting body regions can at first sink deeper into the mattress, but, after a compression of the bulging, a harder spring characteristic becomes effective, which optimally supports the lying person.
  • the progressive spring force achieves a remarkable relaxation, for example, of the spine, so that the new spring core optimally meets the demands with respect to a high springing comfort.
  • both end regions of each spring are shaped in the manner of a bulging. In addition to an optimized lying comfort, this results in a greater load capacity of the spring core.
  • pitches of the wire winding which differ in regions, the spring action of the spring can be influenced.
  • a pitch which is flat toward the ends and steep toward the center supports at first a soft and then a harder springing when the spring core is used.
  • the springs constructed according to the present disclosure may be mutually connected by a spiral wire in the manner of a Bonell spring core. However, they may be used as pocket springs. That is, they are enveloped by a fabric pocket. A plurality of springs form a strand and these strands, arranged side-by-side, are glued to one another in the region of the jacketed springs. The gluing-together takes place, for example, by a hot-melt adhesive, which is applied at the bulges.
  • intermediate layers of an elastic material such as a foamed material, may be provided.
  • the intermediate layer is arranged between two strands and is glued together with the adjacent strands.
  • the pockets enveloping the springs are adapted to the shape of the new spring.
  • fabric strips extending over the entire length of a strand are used for forming the pockets.
  • these fabric strips are connected with one another by ultrasonic sealing, corresponding to the shape of the spring, while forming the above-mentioned pockets.
  • differently shaped springs such as barrel springs, may also be arranged.
  • the center bulging of the barrel can then be inserted into the center constriction of the new spring. If a new spring with only one bulging is used, the opposite side of the spring core can be determined by the inserted barrel springs, so that a turner mattress is obtained which has different lying characteristics.
  • FIG. 1 is a lateral view of an individual spring of a spring core, according to the present disclosure.
  • FIG. 2 is a lateral view of a partial cutout of a spring core, according to the present disclosure.
  • FIG. 3 is a top view of the partial cutout of FIG. 2 .
  • FIG. 4 is a lateral view of a partial cutout of another embodiment of a spring core, according to the present disclosure.
  • FIGS. 5 and 6 are views of a partial cutout of a spring core in a connection region of two individual springs, according to the present disclosure.
  • FIG. 1 shows a helically wound spring 1 of a spring core, according to an embodiment of the present disclosure.
  • Spring 1 is shaped as or includes a bulging 2 , 3 , for example, at its two end regions 11 , while a center part situated in-between bulging 2 , 3 is a throat 4 having a reduced diameter.
  • FIG. 2 shows springs 1 which are disposed side-by-side and are enveloped by pockets 5 .
  • These pockets 5 include a textile material and combine a row of individual springs 1 disposed side-by-side to form a strand or a row.
  • Pockets 5 are formed in that two fabric strips covering individual springs 1 on both sides between two individual springs are mutually connected by ultrasonic sealing, such as sealing seam 7 shown in FIG. 3 .
  • FIG. 3 also shows an elastic intermediate layer 6 , which may include a foamed material.
  • Intermediate layer 6 is arranged between two spring strands, which intermediate layer 6 is glued to two adjacent spring strands and thereby forms a connection element. In their entirety, the intermediate layers 6 result in a completion of the spring core.
  • a mutual spacing of the individual spring strands changes depending on the width of the intermediate layer 6 , which results in a change of the spring characteristic of the spring core.
  • spacers can be used to fill spaces formed between two spring strands.
  • the spacers are also connected with adjoining springs 1 or their pockets 5 .
  • Such spacers may also be formed of a foamed material, but may include springs 1 , which may be barrel springs.
  • the barrel springs rest laterally against the throats 4 of the adjoining springs 1 .
  • the spring 1 has a bulging 2 at only one end region, while the tapered portion, that is, the throat 4 , is continued into the other end region.
  • barrel spring 9 rests against a region of the throat 4 , which barrel spring 9 is constructed as a pocket spring and whose pocket is connected with the pocket of the spring 1 , which connection may be by a gluing-together.
  • the barrel spring 9 projects over the spring 1 , on a side situated opposite the bulging 2 , so that, for example, a turner mattress is formed whose spring characteristic differs on the two sides.
  • the rows can be connected, for example, by cover layers 10 which include a nonwoven covering and are connected on one side with the bulging-out springs 1 and, on the other side, with the barrel springs 9 .
  • cover layers 10 which include a nonwoven covering and are connected on one side with the bulging-out springs 1 and, on the other side, with the barrel springs 9 .
  • FIGS. 5 and 6 show a connection region as an individual unit, by which the fabric strips covering the individual springs 1 on both sides are connected with one another between two springs 1 . In this manner, the pockets 5 are formed.
  • the sealing seams 7 are arranged such that the springs 1 are firmly clamped into the pockets 5 , so that a lateral deflection is virtually excluded.
