Description

The invention relates to a double mattress with two lying in a width direction side by side lying surfaces for two people, with a mattress core, at least one support cushion and a common mattress cover, the mattress core having springs arranged side by side in the width direction and in the longitudinal direction and lying surfaces with different hardnesses and / or lying areas are formed.

Double beds usually consist of a common bed body, which may be uniformly formed with at least one mattress or which is suitable for receiving at least one mattress. Modern box spring beds can be constructed with firmly integrated mattresses. A double bed is for two people and therefore has two beds for the two people.

Insofar as a uniform mattress is used across the width of the double bed, as may be the case in particular for double beds up to a width of 160 cm, there is the problem that persons of different construction of a couple must sleep on the same mattress. As a result, the mattress may be proper and comfortable for one person of the couple while being too hard or too soft for the other person of the couple. In practice, it has been found that mattresses are formed over their longitudinal direction with different lying areas to meet the longitudinally inhomogeneous weight distribution of a person by appropriate support hardening. Also in this regard, there is the problem of the lack of adjustment of the unitary mattress to a person of the couple, if the persons of the couple have different body lengths or trunk lengths.

It is therefore known to equip double beds with two widthwise adjacent different mattresses, but have the disadvantage that they abut one another at a butt joint and ensure in the region of the butt joint, ie in the region of the edges of the two partial mattresses, no longer sufficient support so that a person in the area of the butt joint penetrates more strongly into the mattress. One "falls" into the butt joint between the mattresses.

The disadvantages of one or the other solution for the design of a double bed have been accepted for decades.

By DE 200 12 254 U1 It is known to form a mattress for double beds from two single mattresses, which are surrounded by a common enclosure and which are detachably connected to each other within the enclosure. The purpose of this mattress is that the handling is not a large double mattress required, but can be done in the form of taken out of the common enclosure single mattresses.

By EP 0 828 445 B1 Further, a double mattress in the form of a one-piece mattress structure is known, which is known by coil springs in pockets formed in a series of strands. The connection of the coil springs is made by an adhesive connection of the formed of heat-sensitive material bags. To form different hard lying surfaces for the two persons, the coil springs can be formed differently on one side of the bed, as the coil springs on the other side. In this way, a one-piece spring core is formed, which forms lying surfaces with different support hardnesses and in which the surrounding the spring pockets are interconnected.

By NZ 330 983 A is a double mattress of the type mentioned above known. In this double mattress a mattress core is formed by a one-piece foam or latex block, are introduced into the holes. In the holes spiral springs are introduced, which are arranged so regularly in the length and width direction side by side. This can be done without the training of Partial mattresses two lying surfaces are formed with different lying surfaces in which different coil springs are used in the holes for the different lying surfaces and lying areas or the density of holes for certain zones is increased.

The invention has the object of providing a double mattress of the type mentioned in such a way that a uniformly perceived lying surface is achieved without a noticeable butt joint.

To solve this problem, a double mattress of the type mentioned is inventively characterized in that the mattress core is formed of two adjoining each other in the width direction, each consisting of springs sub-cores, which are connected with a lying in the longitudinal direction butt joint together over the butt joint away are and that located on the butt joint edge springs of the two partial cores are mechanically connected directly by eyelets, spiral wire or textile, plastic or metal filaments or wires and that the split cores are covered by the extending over both lying surfaces support pad.

The invention is based on the idea to determine the hardness and possibly the distribution of Liezogen substantially by the split cores and produce an undivided in handling mattress in that the split cores covered by an over the entire width of the mattress extending support cushion and then from Surround the mattress cover. In this way, it is possible to form a mattress which is uniform in handling and lying comfort, in which the mattress properties on the two lying surfaces are different, because different partial cores determine this lying characteristics. It is possible that the two partial cores lie with a longitudinal joint lying close together and support each other so that an otherwise occurring in the butt joint reduction of the supporting force is not noticeable in appearance.

According to the invention, the split cores are formed with springs which are arranged side by side in the width direction and in the longitudinal direction. The springs customary for spring mattresses are used, which are made of wire material, in particular metal wire, formed coil springs and are used for example to build a pocket spring or Bonnell spring mattress.

The split cores are connected together via the butt joint. In the part cores formed from springs, the connection can be done in a conventional manner by eyelets or by spiral wire. Other direct mechanical connections of the springs, for example with textile, plastic or metal threads or wires, are possible. In this way, located on the butt joint edge springs of the two sub-cores are interconnected. The cohesion of the springs of a sub-core with each other in the usual way, as is common in Bonnell- or pocket spring mattresses, ie via a direct mechanical connection of the springs together or a compound of fabric bags in a pocket spring mattress.

The double bed mattress according to the invention makes it possible, without the formation of a butt joint which is noticeable when lying down, that different support properties on the two lying surfaces for different persons of a pair are possible. Without an individual preparation of the mattress, this is possible, for example, that according to the in the German patent 103 01 557 criteria for a bed for a man and the adjacent bed for a woman is formed. Statistical data on average body length and average body shape of men and women are used as a basis for adjusting the distribution of different resting zones for men and women. However, this is only a preferred embodiment. It is also possible to categorize the reclining surfaces according to other categories, such as by stem length ranges of persons involved, to create double mattresses with different combinations of reclining surface types.

In a simplified - and therefore advantageous for production and storage - form the two lying surfaces but also have an equal distribution of lying areas and be designed only to adapt to different body weights with different degrees of hardness. In an even simpler training, the two reclining surfaces differ only by the degrees of hardness, if, for example, waives a zone education.

The as a section along a width direction in FIG. 1 shown mattress consists of a mattress cover 1, an upper support cushion 2 and a lower support cushion 3 and a mattress core 4, which is formed of two side by side juxtaposed partial cores 5, 6. In the illustrated embodiment, the split cores 5, 6 are formed as pocket spring cores, wherein the pocket spring cores have close to each other in rows and columns adjacent springs 7 in the form of pocket springs. Shown are pocket springs with a barrel-shaped contour, as it is known for pocket spring cores in itself. The split cores 5, 6 abut one another at a butt joint 8 extending in the longitudinal direction of the mattress and are connected to one another there. The connection takes place in that all edge springs 5 ', 6' are connected to one another via a connecting means 9.

The split cores 5, 6 can have different support properties. In the simplest case, for example, the partial core 5 has a degree of hardness H2, while the partial core 6 is designed for a higher degree of hardness H3. This way you can For example, the double bed mattress can be adjusted for a heavier man and a lighter woman.

Between the support pads 2, 3 runs on the outer edge of the mattress, a side cushion 10, which forms a circumferential, the springs 7 enclosing frame.

FIG. 2 shows a plan view of the arrangement of the springs 7 of the split cores 5, 6, which abut in a longitudinally aligned butt joint 8 with the edge springs 5 ', 6' together.

In the illustrated embodiment, both partial mattresses 5, 6 have a zone structure of seven zones Z1 to Z7 to better meet the different support requirements of the body shape. In the same zone distribution of the two partial cores 5, 6, the springs 7 of the two partial cores 5, 6 differ only by their spring hardness, so that the partial core 5 to a softer lying surface with the degree of hardness H2 and the partial core 6 to a harder surface with the hardness H3 leads. Of course, the specified degrees of hardness are mentioned only by way of example. Other combinations of degrees of hardness, including the hardnesses H1, H4 and H5 are also conceivable. In practice, however, the degrees of hardness H2 and H3 dominate.

FIG. 3 shows the connection of the edge springs 5 ', 6' in barrel-shaped pocket springs. Here, the connection is preferably made with a fastening means 9 in the form of an eyelet, which is mounted centrally with respect to the height of the springs, where the bulbous barrel-shaped pocket springs abut each other.

According to FIG. 4 the connection is in cylindrical pocket springs as edge springs 5 ', 6' with connecting means 9, which are also in the form of eyelets, but at the top and bottom of the edge springs 5 ', 6' are mounted.

If the split cores are formed with Bonnell springs as edge springs 5 ', 6', the connection of the edge springs 5 ', 6' can take place with fastening means 9 in the form of a spiral wire, as shown in FIG FIG. 5 is indicated.

In the illustrated embodiment, the springs 7 are disposed in columns corresponding to the longitudinal direction and rows corresponding to the width direction are abutted. Both partial cores 5, 6 have 13 springs side by side in the width direction, while springs 30 are provided in the longitudinal direction. Usually, the springs of one row in the width direction are all the same, while the columns in the longitudinal direction can have springs of different spring hardness, in order to form the different zones Z1 to Z7.
Although the split cores 5, 6 are formed differently, the double mattress according to the invention appears as a uniform mattress, although over the split cores 5, 6 forms two different lying surfaces of example different hardness, but comfort disadvantages by the butt joint 8 avoids that the split cores 5, 6 are covered by support pads 2, 3 uniformly extending over the entire width of the mattress. In principle, the mattress could also be formed with a support pad 2. However, an embodiment with two support pads 2, 3 is preferred, since in this case the mattress can also be occupied by both sides.

In the formation of the split cores 5, 6 with springs 7, the split cores 5, 6 connect to a common mattress core 4, which prevents a noticeable effect of the butt joint 8 in practice.
