Description

The present invention relates to a pocket spring mattress, preferably in combination with a slatted frame, which is used as a support device for a mattress. The mattress is characterized by the fact that its spring hardness, particularly in the shoulder support area, can be easily adjusted. The mattress has a spring basket and at least one overlay, which can be exchanged individually or together to adjust the level of hardness of the mattress. The slatted frame is characterized by the fact that it can be variably adjusted to a variety of heights and spring properties of the slats. The invention further relates to a mattress system with several spring baskets and supports, from which a combination of a spring basket and at least one support can be selected in order to produce a mattress adapted to the needs of the user.

The slatted frame has the advantage that the slats are arranged in areas assigned to a human body and slats only have to be moved within the slatted frame in order to adjust the heights and spring properties.

In general, the slatted frame has two end frame sections, which preferably have the same length, which are pivotally articulated opposite one another on a central frame section or which are rigidly connected to one another. Optionally, each of the terminal frame sections can be pivoted independently of the other on the central frame section, e.g. into a plane common to the central frame section or beyond the plane in which the central frame section lies, e.g. to pivot only one or both of the terminal frame sections, e.g. in order to pivot one or both of the end frame sections for the upper body or the legs higher and further optionally to fix them in a pivoting position. In embodiments in which the end frame sections are rigidly connected to the central frame section, the central frame section can have a pivot joint about which the end frame sections can be pivoted towards one another, for example in order to arrange the end frame sections relative to one another, in particular to arrange the folded slatted frame in one Packaging. Generally preferred, each pivot joint with which a terminal frame section is articulated is arranged with its pivot axis on the side of the longitudinal sides that is opposite the slats. The long sides and their end frame sections can be made of wooden beams, for example with a rectangular cross section, or hollow metal profiles, each of which is divided in the area of a swivel joint. The long sides can be divided in that they have end faces arranged perpendicular to their length, or end faces arranged in a V-shape, with the pivot joint in the area of the smallest distance between the end faces. A pocket spring mattress is preferably placed on the slatted frame.

The invention further relates to a method for transporting a pocket spring core mattress according to the invention, which is arranged in an airtight cover, with the step of evacuating the cover, rolling up the cover with the pocket spring core mattress arranged therein and packing this rolled up cover in a box and transporting it of the box. The end frame sections of a slatted frame according to the invention are preferably pivoted towards one another along one or two swivel joints, the slatted frame is then packed with the end frame sections pivoted towards one another in a separate box, and transported.

From the DE 298 09 859 U1 Modular mattress systems are known that contain a one-part or multi-part mattress core that is connected to a pad and/or a plate can be. Furthermore, for example, from the DE 297 10 758 U1 Mattresses are known that are divided into zones of different hardness. The arrangement of the zones is usually symmetrical or synchronous.

The above-mentioned versions of mattresses have the disadvantage that after purchase it is not possible to individually adapt them to the needs of the user or not in a simple manner (e.g. only by exchanging the mattress).

The DE 10 2015 101 432 B4 describes a slatted frame for supporting a mattress, which has curved spring slats on a frame and spring slats that have a flat, centrally arranged bridge area between end cranked sections, so that the bridge area is arranged higher or lower when these slats are turned.

The above-mentioned versions of mattresses have the disadvantage that after purchase it is not possible to individually adapt them to the needs of the user or not in a simple manner (e.g. only by exchanging the mattress).

It has been shown that conventional slatted frames only allow a limited adjustment by varying the spring action and/or height of slats, which from one end of the slatted frame have a head area, a shoulder area, an adjacent lumbar area, an adjacent pelvic area, a leg area and a foot area exhibit.

The object of the invention is to provide an alternative mattress that can be easily adapted to the needs of the user. In particular, the spring hardness of the mattress should be adjustable at least in sections, for example in the area where the shoulder rests, preferably allowing a simple variation of the degree of hardness, in particular of the shoulder area. The mattress is preferably provided in combination with a slatted frame, which allows a variety of adjustments of the slats in terms of the height relative to the frame and their spring action in order to adapt the slatted frame to a body, the slatted frame providing a general adjustment, in particular for the lumbar area pretends.

The invention solves this problem with the features of the claims and in particular provides a pocket spring mattress with its top facing away from the slatted frame is arranged. The mattress is characterized by the fact that its spring hardness, particularly in the shoulder support area, can be easily adjusted. The mattress has a one-piece spring basket and at least one overlay, which can be replaced individually or together to adjust the hardness of the mattress. The invention further relates to the slatted frame in combination with a mattress system with several, each one-piece spring baskets and supports, from which a combination of one of the spring baskets and at least one support can be selected in order to create a mattress adapted to the needs of the user, optionally in combination with a slatted frame. The invention preferably also relates to a method for adapting a slatted frame of a pocket spring mattress to a human body, wherein the slatted frame is rotated by 180° in the plane in which its frame extends and/or that the slats (11) of the one Shoulder area can be exchanged for the slats of the other shoulder area and / or that the straps of one shoulder area are exchanged for the straps of the other shoulder area. The invention further relates to a method for producing a slatted frame in combination with a pocket spring core mattress, in which the pocket spring core mattress is assembled from a mattress system which contains at least two spring baskets and at least three first supports, with a first of the at least two spring baskets being a first shoulder area with a first spring hardness and a second shoulder area with a second spring hardness, and a second of the at least two spring baskets has a first shoulder area with a third spring hardness and a second shoulder area with a fourth spring hardness, and wherein the at least three first supports each have different degrees of hardness . Furthermore, the method can provide that the spring basket is wrapped together with the first and/or the second edition in a common cover, or alternatively that only the spring basket is wrapped in a cover and only a first edition is applied to one side of the cover .

The pocket spring mattress has

• a one-piece spring basket with a first end and an opposite second end, the distance between the first end and the second end of the spring basket being the length of the spring basket and the length of the mattress, respectively,
• a first side and an opposite second side, each connecting the first end to the second end, the distance between the first side and the second side being the width of the spring basket and the width of the mattress, respectively,
• a top and an opposite bottom, with the distance between The top and bottom are the height of the spring basket and the springs are spiral springs which are arranged with their spring axis parallel to the height of the spring basket, the top being set up as a support surface and the underside facing this when the mattress is arranged on a slatted frame,
• wherein the spring basket is divided into zones arranged parallel to its width, the spring basket having a first shoulder region of a first spring hardness and a second shoulder region of a second spring hardness, the first spring hardness being different from the second spring hardness,
• a first support which connects to the top of the spring basket and can preferably be connected to it,
• optionally a second support, which connects to the underside of the spring basket and can preferably be connected to it,
• a cover containing the spring basket, the first edition and/or optionally the second edition,
• preferably a strip of steel which is arranged between a row of springs arranged adjacent to the circumference of the spring basket and a row of springs adjacent to this,
• on or consists of.

The mattress preferably only has a support on its top side and consists of a spring basket which is encased in a cover and a support which is arranged inside, preferably outside of the cover on the top side of the mattress.

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

Generally, pocket springs are arranged in the spring basket, with their spring axis parallel are aligned with an axis of rotation of the mattress that is arranged parallel to the height of the mattress. Accordingly, the pocket springs are arranged with their spring axis perpendicular to the top and bottom of the mattress. The degree of hardness of the spring basket or the zones of the spring basket is generally determined by the spring strength of the pocket springs arranged therein, with a lower degree of hardness being generated by a lower spring strength and a higher degree of hardness being generated by a higher spring strength.

The spring basket can have at least 5, preferably at least 7 zones, e.g. starting from its first end a first head area, a first shoulder area, optionally a first lumbar area, a pelvic area, optionally a second lumbar area, a second shoulder area and a second head area.

The axis of rotation of the mattress is designed parallel to the height of the spring basket or perpendicular to the top. In general, the mattress can be transferred from a first position to a second position by rotating it about the axis of rotation through 180°, with the second shoulder region preferably being arranged in the second position exactly in the region in which the first shoulder region 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 as large as the distance between the second shoulder area and the second end, and the first and second shoulder areas each have the same dimensions.

It has been shown that the feeling of lying on a mattress is mainly determined by the degree of hardness of the mattress in the shoulder support area, although the degree of hardness in the leg area can be neglected. In the first position of the mattress, the user lies with his shoulder in the first shoulder area of the mattress and his legs in the second shoulder area of the mattress. By rotating the rotation axis through 180°, the mattress is transferred to the second position in which the user rests with his shoulder in the second shoulder area of the mattress and with his legs in the first shoulder area of the mattress.

Individual zones can have the same or different degrees of hardness, independently of one another or the same. The first head region preferably has the same degree of hardness as the second head region. More preferably, the first optionally has Lumbar area has the same degree of hardness as the second lumbar area. Deviating from this, however, according to the invention, the first shoulder region has a degree of hardness that is higher or lower than the second shoulder region, for example measured higher or lower by at least 10% or by at least 20%, for example up to 30% or up to 25% in each case as the average spring strength of the springs contained therein. A lower degree of hardness is preferably formed in that the springs have a smaller diameter, optionally consisting of spring wire of the same thickness and hardness as springs in a range with a higher degree of hardness. All springs are spiral springs whose spring axes are arranged parallel to the height or perpendicular to the top of the spring basket. Generally preferred, all springs, in particular adjacent springs, are arranged with their spring axes in the intersection points along the same lines running parallel to the length and width of the spring basket, so that the springs of smaller diameter are arranged at a greater distance from one another in the width of the spring basket. Further preferably, all springs, in particular adjacent springs, are arranged with their spring axes along the same lines, each running parallel to the length of the spring basket, with the springs with their pockets being arranged adjacent to one another along their circumference and/or in contact with one another. The areas of the pockets that are arranged in contact with one another can be connected to one another, for example glued, or only loosely contact one another when unconnected. In general, adjacent springs are arranged with their spring axes at intersections of the same lines or exactly a grid of lines that run parallel to the length and width of the spring basket, with all springs being arranged without an offset to adjacent springs, or no springs with an offset adjacent springs are arranged.

Due to the same degrees of hardness of the first and second head area, or optionally of the first and second lumbar area, 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, especially in the lumbar area and Pelvic area, in the second position have essentially the same degree of hardness as in the first position.

The spring basket preferably has a circumferential strip of steel which is arranged between a row of pocket springs arranged adjacent to the circumference of the spring basket and a row of pocket springs adjacent thereto, so that the strip of steel runs parallel to the circumference of the spring basket and around exactly the outer row of Pocket springs are spaced from the circumference of the spring basket. The strip steel has a rectangular cross section, with the broad side preferably being arranged parallel to the top side, and more preferably the strip steel being arranged adjacent to the top side or in the plane of the top side. The strip steel, for example, has a broad side of 5 to 20 mm, preferably 10-15 mm, and a thickness of 1 to 4 mm, preferably 2-3 mm. Generally, the strip steel is preferably made of spring steel. A steel strip arranged in this way allows the spring basket to be rolled up about an axis parallel to the top side, parallel to the width or perpendicular to the length of the spring basket, for example for arranging the rolled-up spring basket in a box. In addition, the steel band gives the spring basket sufficient stability, for example to prevent the top from moving against the underside of the spring basket, whereby optionally the spring basket is only covered by a cover, which can consist of a simple layer of fabric. In addition, the steel strip provides sufficient strength for the spring basket in its edge area, for example to prevent a person sitting on the edge from sinking in excessively.

The first edition, also referred to as a topper, preferably has foamed natural latex or foamed 100% natural latex, optionally in a cover, or consists of it. Preferably, the first support is set up to rest over the entire surface of the top of the spring basket and has the same length and width as the spring basket.

The first edition has a degree of hardness that is preferably constant over its entire cross section. The first edition is preferably set up so that its degree of hardness is one which, in combination with the spring basket and optionally further editions, results in an overall hardness of the mattress of H1, H2, H3, H4 or H5.

The optional second overlay may include or consist of foam and/or may include or consist of an elastic wall. Preferably, the second support is set up so that the spring basket rests on it over the entire surface and has the same length and width as the spring basket.

Generally preferred is the mattress including the spring basket, cover and one overlay or first overlay and optionally an additional second overlay, free of adhesive.

Generally, the spring basket is wrapped in a cover, optionally together with the first and/or second edition or alternatively individually or separately from the first and/or second edition. When the mattress is arranged, the cover rests on a slatted frame, preferably directly on the slatted frame.

The spring basket, preferably the cover, is generally preferably set up to be connected to the first and / or second edition, for example by Velcro or zippers, the closure halves of which are each on mutually facing sides of the spring basket or the cover and the first or second The support is arranged appropriately. Optionally, the spring basket in the mattress is only connected to the first and/or second edition in that the spring basket, first edition and optionally second edition are contained in a common cover, in particular are not glued. The mattress preferably consists of a spring basket which is encased in a cover, on one side of which, which forms the top, a support is arranged and connected to the cover, and in particular is free of adhesive. The support, which is also generally referred to here as the first support, can only be connected to the cover by means of a Velcro fastener and/or a zipper.

The mattress system has at least 2 spring baskets and at least 3 first editions, and further optionally at least 2 second editions. In general, a first of the at least 2 spring baskets has a first shoulder area with a first spring hardness and a second shoulder area with a second spring hardness, and a second of the at least 2 spring baskets has a first shoulder area with a third spring hardness and a second shoulder area with a fourth spring hardness , wherein the first, second, third and fourth spring hardnesses preferably differ by at least 10% or at least 20%. Furthermore, the at least 3 first editions each have different degrees of hardness. The at least 3 editions preferably all have the same height. Optionally, the at least 2 second editions each have different degrees of hardness, different thicknesses or consist of a filling made of different materials, for example one made of foam, one made of animal wool, one made of cotton, one made of synthetic fibers, each in a cover made, for example, of cotton fabric consists.

Preferably, first supports that 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.

To produce a mattress from the mattress system, preferably exactly 1 spring basket, exactly 1 first edition, optionally exactly 1 second edition is selected from the mattress system and the spring basket, optionally together with the first and / or the second edition, is wrapped in exactly one common cover, or exactly one overlay, also referred to as the first overlay, is placed on the top of the cover, which only covers the spring basket.

It has been shown that an optimal feeling when lying on a mattress can be created through the interaction of the overall hardness of the mattress. A mattress basket with spring hardness is selected for the user's body weight and height, which has a suitable spring hardness in the first shoulder area and a spring hardness that is one degree of hardness softer or harder in the second shoulder area. By combining two shoulder areas whose spring hardnesses differ by exactly one degree of hardness, the degree of hardness can be varied by one degree of hardness or changed by one degree of hardness by simply rotating around the rotation axis. According to the invention, by selecting a first edition and a spring basket, optionally a second edition, a mattress can be produced from the mattress system that creates an optimal lying feeling and contains a variation in the degree of hardness in the shoulder area. The mattress has the advantage that in order to vary the degree of hardness in the shoulder area, the springs of the spring basket remain unchanged and, for example, do not have to be replaced in segments.

The mattress is arranged with its pelvic area matching the pelvic area of the slatted frame, so that the shoulder areas of the mattress are also arranged matching the shoulder areas of the slatted frame and the lumbar areas of the mattress matching the lumbar areas of the slatted frame.

has or consists of.

The slatted frame according to the invention is based on the knowledge that a central frame section, which forms a pelvic area, can be arranged between two end frame sections, and each of the end frame sections can have a different combination of supports and slats held therein to form one of the end frame sections to configure the desired shoulder area, while the shoulder area of the other end frame section is sufficiently adjustable or adapted as the leg area. The slatted frame therefore offers a shoulder area in each end frame section, so that when aligned horizontally by rotating horizontally, the slatted frame already offers two different, interchangeable shoulder areas. In addition, the straps and slats of the shoulder areas can be freely combined, for example by exchanging straps and/or slats from the second shoulder area with supports and/or slats from the first shoulder area. It has been shown that the individual adaptation of the slatted frame to a body in the shoulder area is much more important than in the leg area, and that the straps and slats that are arranged in the unadjusted shoulder area always form an acceptably adjusted leg area. The slatted frame according to the invention forms two lumbar areas that can be freely combined with the other areas, in particular with the shoulder areas, and it has been found that the lumbar areas can each have four identical slats, the spring action of which can be adjusted, held on height-adjustable supports, each resilient or non-resilient, and a centrally located pelvic area, which extends over four slats, can have spring-action adjustable slats on non-height-adjustable supports.

In general, slats whose spring action can be adjusted are preferably formed by two slats arranged one above the other, bent in parallel, which are clamped against one another with at least two clamping elements which can be moved along the slats, with preferably only the ends of one of the slats being held in a support and the other, parallel slat is shorter.

Non-resilient slats are solid, one-piece slats that have an arcuate center section or are fully arcuate, optionally with offset between their arcuate center section and their ends.

The slats of one shoulder area, which are cranked between their ends and their middle section, can have a curved middle section, particularly convexly curved towards the area on which a mattress is placed, or a flat middle section without load. Generally, these slats are oppositely cranked between their ends and their middle section so that the ends are spaced in a common plane from the plane in which the middle section extends. Such slats can be held by the supports in a position rotated through 180° about their longitudinal axis in order to position their central portion in a different plane, for example in relation to the plane in which the slats of the pelvic area extend.

Non-height-adjustable supports are supports that hold slats on the frame at exactly one height, optionally resiliently, and e.g. supports that have exactly one mounting section so that the recess in the support, in which one end of a slat is held, is at exactly one distance from the Frame is arranged.

Height-adjustable supports have at least two preferably parallel mounting sections, so that their recess, in which one end of a slat is held, is arranged at one of at least two distances from the frame, depending on the mounting section that is connected to the frame.

Resilient supports are made of plastic and have at least one spring section between their recess, into which one end of a slat can be inserted and held therein, and a mounting section which can be connected to the frame. The spring section can, for example, have at least two spring arms, for example at least four spring arms arranged around a cavity. A mounting section can be set up to arrange a plug connection, clamp connection or screw connection that is fixed to the frame. Preferably, the mounting section is set up to arrange a plug-in connection that can be reversibly connected to the frame, for example holes for receiving bolts that are fixed to the frame. Resilient supports are, for example, those with a change in the distance between the recess in which one end of a slat is held and the Mounting section, by at least 1 cm, preferably by at least 2 cm or at least 3 cm by a load of 100 N (about 10 kg).

Non-resilient supports are those in which there is a substantially rigid connection between the mounting section and the recess in which one end of a slat is held and without a spring element, e.g. with a change in the distance between the recess in which one end of a slat is held is, and the assembly section, by a maximum of 1 cm, preferably by a maximum of 0.5 cm or a maximum of 0.2 cm by a load of 100 N (about 10 kg).

Generally, a middle section of a batten can have 50 to 80% of its length between the beams.

Slats, which have a central elongated hole parallel to the longitudinal extent of the slat in their central section, can consist of two, three or four parallel narrow slats, the distance between which forms an elongated hole which optionally extends over the entire length between the supports, preferably the Narrow slats are connected to each other at their ends.

The second frame is preferably designed to be congruent with the frame if its frame sections are arranged in a common plane, and in particular arranged below the frame opposite the direction of pivoting of the end frame sections. Optionally, a second frame can encompass the circumference of the first frame. In embodiments in which the frame sections are rigidly connected to one another, the long sides of the frame can be formed in one piece.

The slatted frame preferably has exactly one frame, which consists of two parallel long sides and attached narrow ends, the long sides being divided in the middle and connected with a hinge.
