EP3525630B1 - Pocket-spring core and method for producing the pocket-spring core - Google Patents

Description

The present invention relates to a pocket spring core according to the preamble of claim 1, a mattress or a cushion with such a pocket spring core according to claim 12 and a method for producing such a pocket spring core according to claim 16.

It is known to design pocket spring cores with zones of different rigidity in sections. As a result, the zones of the pocket spring core can be used for individual parts of a sleeper's body, e.g. the shoulders, feet or buttocks are performed with reduced or increased rigidity compared to other parts of the body.

From the EP 1 603 434 B1 a method is known in which spring strands of pocketed springs lying next to one another and differing in height are connected to one another. This partially results in gaps in the surface of the pocket spring core, which are filled with filler material. This filling material can consist of spring strands made of pocketed springs joined together to form a partial spring core, the springs of which are dimensioned in their height in such a way that the gap is filled and an essentially flat lying surface is produced.

For this purpose, the individual sub-pocket spring cores, i.e. those with the springs that are different in height and those that fill a gap, are each produced separately, with previously formed similar spring strands of pocketed springs being connected to one another by, for example, gluing.

The partial spring core filling a gap is placed in the gap formed and the pocket spring core completed in this respect is then provided with one or more layers of padding and / or covered with a fabric, so that a pocket spring core mattress or a cushion with zones of different stiffness is created.

A disadvantage of the technical teaching of the EP 1 603 434 B1 is the separate manufacture of the respective spring strands from pocketed springs, which then have to be manually put together or put together first to form a partial spring core and then to form the entire spring core. This results in a complex production with correspondingly high costs, in particular due to the production-logistical effort and the technical handling effort that is usually to be carried out manually.

Through the technical teaching of the DE 10 2013 107 255 A1 the joining of separately manufactured pocket spring strands with respectively different, in particular differently high springs for the production of a zoned pocket spring core was automated by a device. This reduced the cost of manufacturing a zoned pocket spring core compared to EP 1 603 434 B1 can already be significantly reduced.

The disadvantage of the solution DE 10 2013 107 255 A1 is the still required, separate production of the required pocket spring strands, each with different springs, in particular springs of different heights, for producing a zoned pocket spring core.

In the WO 03/096847 A1 A zoned pocket spring core is disclosed in which two different springs, in particular springs of different heights, are used in one pocket, the respective pockets of the different springs being arranged vertically one above the other, so that a pocket spring core with pocket spring strand sections is created and each pocket spring strand section has at least two layers of pocketed springs has, in which the pockets of each spring are closed by welds.

Through the technical teaching of the WO 03/096847 A1 a complete pocket spring strand section or a complete spring strand with two or more layers of different springs, in particular springs of different heights, can be produced in one operation. The WO 03/096847 A1 thus overcomes the disadvantage of the separate manufacture of pocket spring strands each with different springs.

The invention has the object of creating a zoned pocket spring core which, compared to the prior art, can be produced more easily and thus more cost-effectively.

The present invention solves this problem by the subject matter of claim 1. It also creates the subject matter of claim 12 and the method of claim 16.

According to the characterizing part of claim 1, it is provided that at least one of the second zone (s) of the pocket spring core has at least one channel-like depression.

The invention is therefore based on the idea that in at least one zone or in several zones of the pocket spring core that have a lower stiffness than other zones or another zone of the pocket spring core, the lower stiffness of this zone (s) by a defined omission of springs to create.

This advantageously results in a cost-optimized zoned pocket spring core.

In a preferred embodiment of the invention, the channel-like depressions extend through the entire width of the pocket spring core. This results in an advantageously simple, uncomplicated production and thus a zoned pocket spring core that is cost-effective.

In a further preferred embodiment of the invention, the second spring strand section has three vertically superposed layers of a plurality of helically wound first compression springs in a first, upper layer, second compression springs in a second, middle layer and first compression springs in a third, lower layer on. As a result, part of a zone with comparatively low rigidity can advantageously be produced in an automated manner.

The height of the second spring strand section advantageously corresponds to the height of the first spring strand section. This results in optimized support through the zoned pocket spring core.

In a further preferred embodiment variant of the invention, the height of the third spring strand section is less than the height of the first spring strand section and is less than the height of the second spring strand section.

It is advantageous that the textile material from which the pockets, in which the compression springs of the spring strand sections are pocketed, is a fleece. This results in an advantageously inexpensive producibility of the zoned pocket spring core.

In a further preferred embodiment of the invention, the pocket is closed by means of horizontal weld seams and vertical weld seams. The weld seams advantageously achieve automated production of the spring strands with short cycle times.

It is advantageous that the weld seams are produced by an ultrasonic welding process. As a result, the production of the zoned pocket spring core is advantageously simplified and thus made inexpensive.

In a further preferred embodiment of the invention, the second spring strand section and the third spring strand section of the second zone are arranged in a pattern. The second zone advantageously has a pattern of in each case a single or several consecutive second spring strand section (s), on which a single or several consecutive third spring strand section (s) follows.

By arranging the spring strands in a defined pattern, it is possible to automate and thus easily implement the cost-effective zoning of the pocket spring core.

Further advantageous embodiments of the invention can be found in the subclaims.

Embodiments of the subject matter according to the invention are shown in the drawings and are described in more detail below. It shows:

a front view of a zoned pocket spring core according to the invention;

Figure 2:

a front view of a variant of the zoned pocket spring core according to Fig. 1 ;

Figure 3:

Figure 4:

a front view in section of a mattress or a cushion with a zoned pocket spring core Fig. 2 .

In the Fig. 1 a front view of a zoned pocket spring core 1 is shown. The pocket spring core 1 accordingly has at least one first zone 2 and at least one second zone 3. The first zone 2 differs from the second zone 3 in terms of its rigidity, the term "rigidity" here meaning the resistance to (elastic) deformation.

The first zone 2 has at least two rows or rows of a first spring strand section 4. The first spring strand section 4 has a plurality of similar, helically wound compression springs 5, which are each inserted individually in a pocket 6 surrounding the individual compression spring 5.

The term “row” or “line” relates to a direction transverse or perpendicular to the greatest longitudinal extent of the finished zoned pocket spring core 1.

The pocket 6 is each made of a sheet-like, textile material such as a fleece, the pocket 6 -related to the plane of the drawing Fig. 1- is closed by horizontal welds 7 and vertical welds 8. The weld seams 7, 8 are produced here by an ultrasonic welding process. Alternatively, other welding methods for producing the weld seams 7, 8 are also possible.

A spring strand made of individually pocketed compression springs 5 is usually produced as a quasi-endless strand in an automated process by a machine.

The at least two rows of the first spring strand section 4, which form the first zone 2 of the pocket spring core 1, are each formed by cutting the endless strand to length to form the first spring strand section 4. The cutting to length takes place in the area of the vertical weld seam 8 between two pockets 6, so that the respective pockets 6 are not damaged. The at least two rows or rows of the first spring strand section 4, which form the first zone of the pocket spring core 1, are formed by aligning, placing and gluing the contact points of the row or row-wise aligned and abutting spring strand sections 4.

The cutting of the strands to the respective spring strand sections 4 as well as the alignment, lining up and gluing of the spring strand sections 4 are also carried out in an automated process by a machine.

At least one of the second zone (s) 3 of the zoned spring core 1 has at least one row or row of a second spring strand section 9 and at least one row or row of a third spring strand section 10.

The second spring strand section 9 and the third spring strand section 10 are arranged in a pattern. The pattern is in Fig. 1 a simply alternating pattern is chosen as an example. After a single second spring strand section 9, there follows a single third spring strand section 10, which is again followed by a single second spring strand section 9, etc.

Alternatively, other patterns are also possible in the arrangement of the second spring strand section 9 and the third spring strand section 10 in the second zone 3 of the zoned pocket spring core 1. For example, it is also possible that the second zone 3 has a pattern of in each case a single or several successive second spring-strand sections 9, on which a single or several consecutive third spring-strand sections 10 follow.

The second spring strand section 9 has at least two in relation to the plane of the drawing Fig. 1 vertically superposed layers of a plurality of helically wound first compression springs 11 in a first, upper layer and second compression springs 12 in a second, lower layer, each individually in a pocket 13 enclosing the individual first compression spring 11 and each individual second Compression spring 12 enclosing pocket 14 are used.

The pockets 13, 14 are made of a sheet-like, textile material, such as a fleece, the pockets 13, 14 -related to the plane of the drawing Fig. 1 - Are each closed by horizontal welds 15 and vertical welds 16. The weld seams 15, 16 are produced here by an ultrasonic welding process. Alternatively, other welding methods for producing the weld seams 15, 16 are also possible.

The height of the second spring strand section 9 -also its dimension in the vertical direction in relation to the plane of the drawing Fig. 1 - corresponds to the height of the first spring strand section 4.

A spring strand made up of two layers of individually pocketed compression springs 11, 12 is usually produced as a quasi-endless strand in an automated process by a machine.

The compression springs 11, 12 differ here in their height - that is, their dimension in the vertical direction in relation to the plane of the drawing Fig. 1 - and in the winding pitch. The second compression spring 12 is more rigid than the first compression spring 11.

The first compression spring 11 and the second compression spring 12 of the second spring strand section 9 are arranged vertically one above the other. Both compression springs 11, 12 act in the direction of arrow "F" in FIG Fig. 1 so like a series connection of compression springs. This results in an overall stiffness of an imaginary substitute spring of this series connection which is less than the stiffness of the first compression spring 11 with the lowest individual stiffness of the series connection of the compression springs 11, 12.The series connection of the compression springs 11, 12 thus results - at least approximately - a progressive spring constant of the conceptual substitute spring.

The third spring strand section 10 is constructed here analogously to the first spring strand section 4. Therefore, to avoid repetition, only deviations and additions to the first spring strand section 4 are described here. The third spring strand section 10 has a plurality of similar, helically wound second compression springs 12, which are each inserted here individually in a pocket 14 enclosing the single second compression spring 12. The second compression spring 12 of the third spring strand section 10 has, in comparison to the compression spring 5 of the first spring strand section 4, a smaller winding pitch and a smaller height.

Alternatively, the third spring strand section 10 can also have several layers of compression springs which are arranged vertically one above the other. In this case, each layer has a plurality of identical, helically wound compression springs, which are each inserted individually in a pocket surrounding the individual compression spring.

It is essential that the height of the third spring strand section 10 is less than the height of the first spring strand section 4 and is less than the height of the second spring strand section 9.

As a result of the pattern formed by the arrangement of the second spring strand section 9 and here the third spring strand section 10, at least one of the second zone (s) 3 of the pocket spring core 1 has channel-like depressions 17. The channel-like depressions preferably extend through the entire width of the pocket spring core 1. This advantageously results in a cost-optimized zoned pocket spring core 1. With “width”, the dimension of the pocket spring core 1 is perpendicular to the plane of the drawing Fig. 1 meant.

The second zone (s) 3 - especially the one (s) with the channel-like depressions 17 - has a significantly lower rigidity than the first zone 2 of the spring core 1 and is therefore arranged in areas of the spring core 1 in which certain body parts (e.g. shoulders or buttocks) of a sleeper should dip deeper into the spring core 1 than other body parts.

Due to the overall progressive spring stiffness of the second zone (s) 3 - in particular the one (s) with the channel-like depressions 17 - the corresponding part of the sleeper's body initially sinks relatively deep into the second zone 3, and then essentially through the second compression springs 12 of the second spring strand 9 and the second compression springs 12 of the third spring strand 10 to be supported. As a result, the sleeper's body is advantageously supported at all points during sleep so that the sleeper can advantageously sleep restfully. This also results in an advantageously pleasant feel for the sleeper.

Alternatively, the pocket spring core 1 can also have more than two zones 2, 3, each with a different rigidity, each of these zones being constructed either according to the model of the structure of the first zone 2 or according to the model of the structure of one of the second zones 3. It is essential to the invention that at least one second zone 3 has trough-shaped depressions 17 with a rigidity that is reduced in comparison to the first zone 2.

In Figure 2 FIG. 11 is a front view of a variant embodiment of the zoned pocket spring core 1 according to FIG Fig. 1 shown. In order to avoid repetition, only deviations, changes or additions to the in Fig. 1 shown and described above embodiment of the zoned pocket spring core 1 described.

The first spring strand section 4 a has a plurality of similar, helically wound compression springs 18, which are each inserted individually in a pocket 22 surrounding the individual compression spring 18.

The pocket 22 is each made of a sheet-like, textile material, such as a fleece, the pocket 22 -related to the plane of the drawing Fig. 2 - Is closed by horizontal weld seams 23 and vertical weld seams 24. The weld seams 22, 23 are produced here by an ultrasonic welding process. Alternatively, other welding methods for producing the weld seams 22, 23 are also possible.

In contrast to the second spring strand section 9 of the second zone 3 in Fig. 1 has the second spring strand section 9a of the second zone 3a with the channel-like depressions 17 three in relation to the plane of the drawing Fig. 2 vertically superposed layers each of a plurality of helically wound compression springs 11, 12.

The layer structure of the spring strand section 9a each has a first compression spring 11 in a first, upper layer, in each case a second compression spring 12 in a second, middle layer and in each case a first compression spring 11 in a third, lower layer, each individually in a individual first compression spring 11 enclosing pocket 13 and the respective individual compression spring 12 enclosing pocket 14 are used.

The height of the second spring strand section 9a -also its dimension in the vertical direction in relation to the plane of the drawing Fig. 2 - corresponds to the height of the first spring strand 4a.

The third spring strand section 10a of the second zone (s) 3a with the channel-like depressions 17 is constructed here analogously to the first spring strand 4a. The third spring strand 10a accordingly has a plurality of similar, helically wound second compression springs 12, which are each inserted individually in a pocket 14 surrounding the individual second compression spring 12. Accordingly, the second compression spring 12 of the third spring strand section 10a has a smaller coil pitch and a smaller height than the compression spring 18 of the first spring strand section 4a.

Alternatively, the third spring strand section 10a can also have a plurality of layers of compression springs which are arranged vertically one above the other. In this case, each layer has a plurality of identical, helically wound compression springs, which are each inserted individually in a pocket surrounding the individual compression spring.

It is essential that the height of the third spring strand section 10a is less than the height of the first spring strand section 4a and less than the height of the second spring strand section 9a.

The second spring strand section 9a and the third spring strand section 10a are here arranged in a pattern. The pattern is in Fig. 2 a simply alternating pattern is chosen as an example. After a single second spring strand section 9a, there follows a single third spring strand section 10a, which is again followed by a single second spring strand section 9a, etc.

Alternatively, other patterns in the arrangement of the second spring strand section 9a and of the third spring strand section 10a in the second zone (s) 3a with the channel-like depressions 17 are also possible. So it is e.g. It is also possible for the second zone (s) 3a with the channel-like depressions 17 to have a pattern of one or more consecutive second spring strand sections 9a, followed by a single or several consecutive third spring strand sections 10a.

Due to the pattern which is formed by the arrangement of the second spring strand section 9a and the third spring strand section 10a, at least one of the second zone (s) 3a of the pocket spring core 1a has channel-like depressions 17. Deviating from the zoned pocket spring core 1 after Fig. 1 the channel-shaped depressions 17 lie in the vertical direction above and below the second, central compression spring 12 of the second spring strand section 9a. This advantageously results in a cost-optimized zoned pocket spring core 1a.

In a further alternative design of the zoned pocket spring core 1a according to Fig. 2 it is also possible that the second zone (s) 3a with the channel-like depressions 17 from a pattern of alternately arranged second spring strands 9 according to Fig. 1 is constructed. The pattern can also have a single or several consecutive second spring strand section (s) 9, in which the recess 17 is above the second compression springs 12 and then one or several consecutive ones (n) have second spring strand section (s) 9, in which the recess 17 results below the second compression springs 12 in each case. This results in an advantageously cost-optimized zoned pocket spring core 1a.

The zoned pocket spring core 1a has a symmetrical structure with respect to its in Fig. 2 shown front view.

In Fig. 3 FIG. 16 is a front view in section of a mattress 19 or a cushion with the zoned pocket spring core 1 according to FIG Fig. 1 shown. To avoid repetition, the in Fig. 1 The embodiment of the zoned pocket spring core 1 shown and described above only describes additions that relate to the mattress 19. The term “mattress” used in the following also applies synonymously in the context of the present invention for a cushion, for example for a piece of furniture for sitting or lying on.

In addition to the zoned spring core 1, the mattress 19 has a first cushion layer 20a and a second cushion layer 20b. The cushion layers 20a, 20b are made of an elastic material, such as a foamed plastic, and in relation to the plane of the drawing Fig. 3 each arranged vertically above and below the zoned pocket spring core 1 over its entire extent.

The arrangement of the first cushion layer 20a covers the channel-like depressions 17 which the zoned pocket spring core 1 forms, so that the mattress 19 forms channel-like hollow chambers 21. The channel-like hollow chambers 19 extend through the mattress 19, preferably over the entire width of the mattress 19. “Width” means the smaller dimension of the lying surface of the mattress 19. The channel-like hollow chambers 21 take on aqueous secretions formed by perspiration of the sleeper during sleep, so that these secretions are not in the upper Pad layer 20a remain and can therefore evaporate more quickly. This results in a mattress 19 with advantageously improved hygienic properties.

The mattress 19 is also completely enveloped with a textile cover material (not shown here).

In Fig. 4 FIG. 13 is a sectional front view of a variant embodiment of the mattress 19 or a cushion according to FIG Fig. 3 with the zoned pocket spring core 1a Fig. 2 shown. To avoid repetition, the in Fig. 2 shown and described above embodiment of the zoned pocket spring core 1a described only additions that the mattress 19a according to Fig. 4 affect. The term “mattress” used in the following also applies synonymously in the context of the present invention for a cushion, for example for a piece of furniture for sitting or lying on.

In addition to the zoned spring core 1a, the mattress 19a has a first cushion layer 20a and a second cushion layer 20b. The cushion layers 20a, 20b are made of an elastic material, such as a foamed plastic, and in relation to the plane of the drawing Fig. 4 each arranged vertically above and below the zoned pocket spring core 1a over its entire extent. In the Fig. 4 illustrated mattress 19a is also known in technical terms as so-called. Reversible mattress because it is in relation to the front view (see Fig. 4 ) is constructed symmetrically. Furthermore, the mattress 19a can each have different cover fabrics on its lying sides, which define, for example, a “summer side” and a “winter side”.

The arrangement of the first cushion layer 20a covers the channel-like depressions 17 that the zoned pocket spring core 1a forms, so that the mattress 19a forms channel-like hollow chambers 21a. Notwithstanding the mattress 19 after Fig. 3 the mattress 19a has the channel-like hollow chambers 21 here analogous to the channel-like depressions 17 of the zoned pocket spring core 1a, each vertically below the first cushion layer 26a and vertically above the second cushion layer 26b.

The channel-like hollow chambers 21 absorb aqueous secretions of the sleeper formed by perspiration during sleep, so that these secretions do not remain in the upper cushion layer 20a and can therefore evaporate more quickly. This results in a mattress 19a - here a reversible mattress - with advantageously improved hygienic properties on both sides.

The following procedure is specified for the production of the zoned pocket spring core 1, 1a:
First, wire is used for the compression springs 5, 11, 12, 18, the textile material for the pockets 6, 13, 14, 22, a machine for the automated production of endless spring strands from pocketed springs, a machine for separating the spring strands and aligning them , Juxtaposition and gluing of spring strand sections and adhesive for gluing the spring strand sections 4, 4a, 9, 9a, 10, 10a are provided.

In a subsequent process step, the compression spring 5, 18 is wound from the wire by the machine for the automated production of endless spring strands from pocketed springs and into a pocket 6, 22, which is open at least on one side and formed by the welds 7, 8, 23, 24 of a welding process inserted from the textile material and the pocket 6, 22 closed by a weld 7, 8, 23, 24 and thus the first spring strand of pocketed compression springs 5, 18 is produced.

In a further process step, the first compression springs 11 and the second compression spring 12 are each wound through the machine and each inserted into a pocket 13, 14, which is open at least on one side and formed by the welds 15, 16 of a welding process, and the respective pocket 13, 14 is inserted through a The weld seam 15, 16 is closed and the second spring strand of pocketed compression springs 11, 12 arranged vertically one above the other is thus produced. This process step is preferably carried out on a second machine in parallel with the preceding process step.

In a subsequent process step, the second compression spring 12 is wound from the wire by the machine and inserted into a pocket 14 made of the textile material, which is open at least on one side and formed by the welds 15, 16 of a welding process, and the pocket 14 is inserted through a weld 15, 16 closed and thus the third spring strand of pocketed compression springs 12 produced. This process step is preferably carried out on a second machine in parallel with the two preceding process steps.

In a subsequent process step, the respective endless spring strand sections are separated in the machine for separating the spring strands and aligning, laying together and gluing spring strand sections 4, 4a, 9, 9a, 10, 10a and the resulting spring strand sections 4, 4a, 9, 9a, 10, 10a aligned, lined up in a defined pattern and glued together, so that the zoned pocket spring core 1, 1a is formed with at least one first zone 2 and one second zone 3, with at least one zone 3 of the at least two zones 2, 3 Has channel-like depressions 17.

The specified method advantageously simplifies the manufacture of the zoned pocket spring core 1, 1a. This advantageously creates an inexpensive zoned pocket spring core 1, 1a.
