Description

[0001] The present invention relates to a pocket spring mattress. The mattress is characterized by the fact that its spring firmness, particularly in the shoulder support area, can be easily adjusted. The mattress comprises a spring cage and at least one topper, which can be replaced individually or together to adjust the firmness of the mattress.

[0002] The invention further relates to a mattress system with a plurality of spring baskets and toppers, from which a combination of a spring basket and at least one topper can be selected in order to produce a mattress adapted to the needs of the user.

[0003] Modular mattress systems are known from DE 298 09 859 U1, which contain a single or multi-part mattress core that can be connected to a topper and / or a plate.

[0004] EP 2 611 335 B1 describes a mattress with six different zones that can be rotated horizontally for adjustment. Mattresses with two, three, or six firmness zones are shown, each in three versions, in which the top

[0005] US Pat. No. 5,868,383 A describes the manufacture of pocket-spring mattresses by arranging coil springs in pockets of a continuous pocket strip. The springs can be arranged in three or six zones, each with a different spring strength.

[0006] US 9 974 395 B2 describes pocket spring mattresses in which the different areas, for example five different areas, can be arranged by the type of arrangement of springs, for example in the densest packing or with gaps, in order to set different degrees of firmness.

[0007] Furthermore, mattresses divided into zones of varying firmness are known, for example from DE 297 10 758 U1. The arrangement of the zones is usually symmetrical or synchronous.

[0008] The aforementioned types of mattresses have the disadvantage that after purchase, individual adaptation to the needs of the user is not possible or not possible in a simple way (e.g. only by exchanging the mattress). Object of the invention

[0009] The invention aims to provide an alternative mattress that can be easily adapted to the user's needs. In particular, the mattress should be adjustable in its spring firmness, at least in certain sections, e.g., in the area where the shoulder rests. Description of the invention

[0010] The invention solves the problem with the features of the claims and in particular provides a pocket spring mattress which - a one-piece spring cage having a first end and an opposite second end, wherein the distance between the first end and the second end of the spring cage is the length of the spring cage or the length of the mattress, a first side and an opposite second side, each connecting the first end to the second end, wherein the distance between the first side and the second side is the width of the spring cage or the width of the mattress, a top side and an opposite bottom side, the distance between the top side and the bottom side being the height of the spring basket, the top side being designed as a support surface and the bottom side facing the slatted frame when the mattress is placed on the slatted frame, wherein the spring cage is divided into zones arranged parallel to its width, wherein the spring cage has a first shoulder region of a first spring hardness and a second shoulder region of a second spring hardness, wherein the first spring hardness is different from the second spring hardness, - a first support which adjoins the top of the spring basket and is preferably connectable to it, - optionally a second support, which is connected to the underside of the spring basket and can preferably be connected to it, - a cover in which the spring basket, the first support, and / or optionally the second support are contained, or consists of it. The mattress according to the invention preferably has a support only on its upper side and consists of a spring basket encased in a cover and a support arranged inside, preferably outside, the cover on the upper side of the mattress.

[0011] The spring basket is generally constructed in one piece, so that the individual zones cannot be removed separately from the spring basket. When the mattress is arranged on a slatted frame, the spring basket is generally arranged with its underside facing the slatted frame and its upper side facing away from the slatted frame, with only one support being arranged preferably on the upper side, within a cover enveloping the spring basket or on the outside of a cover enveloping the spring basket. In particular, the mattress is not reversible, i.e. it is not suitable for rotating about an axis of rotation parallel to the length and / or width of the spring basket and resting with the upper side, on which the first support is arranged, adjacent to a slatted frame.

[0012] Generally, pocket springs are arranged in the spring cage, with their spring axes aligned parallel to the mattress's rotation axis, which is parallel to the height of the mattress. Accordingly, the pocket springs are arranged with their spring axes perpendicular to the top and bottom of the mattress. The firmness of the spring cage, or the zones within the spring cage, is generally determined by the spring strength of the pocket springs arranged within it, with a lower degree of firmness being achieved by a lower spring strength, and a higher degree of firmness being achieved by a higher spring strength.

[0013] The spring basket has 7 zones, starting from its first end a first head area, a first shoulder area, a first lumbar area, a pelvic area, a second lumbar area, a second shoulder area and a second head area.

[0014] The mattress's axis of rotation is parallel to the height of the spring basket or perpendicular to the top. In general, the mattress can be moved from a first position to a second position by rotating it 180° around the axis of rotation. In the second position, the second shoulder area is preferably arranged exactly in the area in which the first shoulder area is arranged in the first position, and vice versa, so that the second shoulder area takes the place of the first shoulder area, and vice versa. For this purpose, the distance between the first end and the first shoulder area is preferably exactly the same as the distance between the second shoulder area and the second end, and the first and second shoulder areas each have the same dimensions.

[0015] It has been shown that the comfort of lying on a mattress is primarily determined by the firmness of the mattress in the shoulder support area, while the firmness in the leg area can be neglected. In the first position of the mattress, the user rests with their shoulder in the first shoulder area of ​​the mattress and their legs in the second shoulder area. By rotating the mattress 180° around the rotation axis, the mattress is transferred to the second position, in which the user rests with their shoulder in the second shoulder area of ​​the mattress and their legs in the first shoulder area of ​​the mattress.

[0016] Individual zones can, independently of one another or identically, have the same or different degrees of hardness. According to the invention, the first head region has the same degree of hardness as the second head region. Furthermore, the first lumbar region has the same degree of hardness as the second lumbar region. However, in contrast to this, the first shoulder region according to the invention has a degree of hardness that is higher or lower than the second shoulder region, e.g., higher or lower by at least 10% or by at least 20%, e.g., in each case up to 30% or up to 25%, measured as the average spring strength of the springs contained therein.

[0017] By having the same degree of hardness in the first and second head areas, or the first and second lumbar areas, the mattress has the advantage that by rotating around the axis of rotation only the degree of hardness of the shoulder area can be varied and the other zones of the mattress, in particular in the lumbar and pelvic areas, have essentially the same degree of hardness in the second position as in the first position.

[0018] The first layer, also referred to as the topper, preferably comprises foam, optionally in a cover, or consists of foam. The first layer is preferably designed to rest completely on the top surface of the spring cage and has the same length and width as the spring cage.

[0019] The first layer has a firmness level that is preferably constant across its entire cross-section. The first layer is preferably designed so that its firmness level, in combination with the spring basket and optionally additional layers, results in an overall mattress firmness of H1, H2, H3, H4, or H5.

[0020] The optional second support may comprise or consist of foam and / or comprise or consist of an elastic wall. Preferably, the second support is configured so that the spring cage rests on it over its entire surface and has the same length and width as the spring cage.

[0021] Generally speaking, the mattress, including the spring basket, cover and one layer or first layer and optionally an additional second layer, is free of adhesive.

[0022] Generally, the spring basket is encased in a cover, optionally together with the first and / or second support, or alternatively individually or separately from the first and / or second support. When the mattress is placed on a slatted frame, the cover rests on top, preferably directly on the slatted frame.

[0023] The spring basket, preferably the cover, is generally preferably designed to be connected to the first and / or second support, e.g. by means of hook-and-loop fasteners or zippers, the closure halves of which are each arranged to fit on mutually facing sides of the spring basket or the cover and the first or second support. Optionally, the spring basket in the mattress is only connected to the first and / or second support in that the spring basket, first support and optionally second support are contained in a common cover, in particular are not glued. Preferably, the mattress consists of a spring basket which is wrapped in a cover, on one side of which, which forms the upper side, a support is arranged and connected to the cover, and is in particular free of adhesive. The support, which is generally also referred to here as the first support, can be connected to the cover only by means of a hook-and-loop fastener and / or a zipper.

[0024] A mattress system according to the invention comprises at least two spring baskets and at least three first supports, and optionally furthermore at least two second supports. In general, a first of the at least two spring baskets has a first shoulder region with a first spring hardness and a second shoulder region with a second spring hardness, and a second of the at least two spring baskets has a first shoulder region with a third spring hardness and a second shoulder region with a fourth spring hardness, wherein the first, second, third and fourth spring hardness preferably differ by at least 10% or at least 20%. Furthermore, the at least three first supports each have different degrees of hardness. Preferably, the at least three supports all have the same height. Optionally, the at least two second supports each have different degrees of hardness, different thicknesses or consist of a filling made of different materials, e.g.one made of foam, one made of animal wool, one made of cotton, one made of synthetic fibers, each in a cover made of, for example, cotton fabric.

[0025] Preferably, first supports which have different degrees of hardness and / or consist of a shell with a filling made of different materials all have the same height or thickness.

[0026] To produce a mattress from the mattress system, preferably exactly 1 spring basket, exactly 1 first layer, optionally exactly 1 second layer is selected from the mattress system and the spring basket, optionally together with the first and / or the second layer, is wrapped in exactly one common cover, or exactly one layer, also referred to as the first layer, is arranged on top of the cover that only wraps the spring basket.

[0027] It has been shown that an optimal lying feeling on a mattress can be created by the interplay of the overall firmness of the mattress. In this case, a mattress basket with spring firmness is selected for the body weight and height of the user. This mattress basket has a suitable spring firmness in the first shoulder area and a spring firmness that is one degree softer or harder in the second shoulder area. By combining two shoulder areas whose spring firmnesses differ by exactly one degree, the degree of firmness can be varied or changed by one degree by simply rotating it around the axis of rotation. According to the invention, by selecting a first layer and a spring basket, optionally a second layer, a mattress can be produced from the mattress system that creates an optimal lying feeling and contains a variation in the degree of firmness in the shoulder area.The mattress has the advantage that, in order to vary the firmness in the shoulder area, the springs in the spring basket remain unchanged and do not have to be replaced segment by segment.

[0028] The invention will now be described in more detail with reference to the figures shown in - Fig. 1 a spatial view of an embodiment of the spring cage, and - Fig. 2 shows an embodiment of the mattress in longitudinal section.

[0029] In general, the same reference numbers in the figures indicate elements with the same functions.

[0030] Fig. 1 shows a spring cage F in a three-dimensional view. The spring cage F has a first end 101 and an opposite second end 102, wherein the distance between the first end 101 and the second end 102 is the length 100L of the spring cage F. The spring cage is further delimited by a first side 103 and a second side 104 opposite the first side, wherein the distance between the first side 103 and the second side 104 is the width 100B of the spring cage F. In addition, the spring cage F has a top side 105 and a bottom side 106, wherein the distance between the top side 105 and the bottom side 106 is the height 100H of the spring cage.

[0031] As from Fig. 2, pocket springs 121 are each aligned in the spring cage F with their spring axis parallel to the rotation axis 107 of the spring cage.

[0032] Further shows Fig. 1, the spring cage F in this embodiment is divided into 7 zones 111-117, each of which is separated from one another parallel to the width 100B of the spring cage F. In detail, the spring cage F in the embodiment shown here has, starting from the first end 101, a first head region 111, a first shoulder region 112, a first lumbar region 113, a pelvic region 114, a second lumbar region 115, a second shoulder region 116, and a second head region 117.

[0033] By rotating about the rotation axis 107 by 180°, the spring cage F can be transferred from a first position shown here into a second position in which, according to the embodiment shown, the second head region 117 takes the place of the first head region 111, the second shoulder region 116 takes the place of the first shoulder region 112, and the second lumbar region 115 takes the place of the first lumbar region 113.

[0034] The Fig. The mattress 100 shown in Figure 2 has, in the embodiment shown, a first support 108 adjacent to the top side 105 of the spring basket F, and a second support 109 adjacent to the bottom side 106 of the spring basket F.
