Abstract

Lying system with frame and a supporting arrangement on which a horizontally divided mattress is laid, which mattress contains at least one spring interior comprising springs made of steel wire which are arranged in rows side by side and are connected to one another, part of these springs being adapted, by addition of further components, with respect to their varying height as a result of the weight loading due to the person resting on the system, to the weight, the height and the physique of the person and at the same time the varying height of part of the springs by at least one additional weight inserted horizontally, in the transverse direction of the system, into a spring interior and/or by at least one flexible force-distributing element placed, in the transverse direction of the system, upon a spring interior.

Description

The invention relates to a reclining system with a frame and a support device on which a horizontal un divided mattress is stored, which at least one Fe the core consists of arranged side by side in rows of the connected springs made of steel wire, where a Part of these springs by adding additional components in terms of their height as a result of Weight load by the person resting on the system is matched to the weight, size and shape of the Person.

In the patent DE 25 38 725 C2 is a one-piece Mattress with spring core described, in which a part of the Springs of the innerspring in the area of the ones they form Cavities with differently shaped profile bodies is filled out. As a result, the support force distribution is un can be formed below the lying surface of the mattress so that the Support of muscles and joints of the system in un person using different sleeping positions  adjusted according to body size and body weight can be.

Such a mattress construction is due to the large number e.g. T. different components and their type of inte cost in the area of the springs of the innerspring dig. That is why mattresses of this type only come for the sick houses and are only such in the private sector Accessible to those who have the resulting relatively high Can accept price. Nor is it possible to get one mattress provided for a specific person by means of fewer steps and without manual work modify that they meet the individual needs of a another person with a different figure, e.g. B. with a shorter or longer upper body. Is further a subsequent fine-tuning correction of the Stützver holding the mattress, which may be in the lumbar and buttocks area can be particularly important due to the use of experiences or thera achieved effects in turn only with greater effort to carry out and also requires manual work ten.

A bed system of this type should not only be part of the The requirements listed below, but all possible largely correspond:

• - Support muscles and joints of the system in un person using different sleeping positions without the individually tolerable tensions, ins especially in the area of the lumbar vertebrae and buttocks, but also in the area of the shoulders and calves be paced.
• - Possibility of an easy to carry out, subsequent Fine-tuning correction of the support force distribution inside half of the mattress based on experience and / or regeneration of the spine that has occurred Person using the system.
• - Presence for one is sufficient the, if possible by operating a device flowable air exchange in the area of the body surface the person resting on the system to avoid Water film formation on the skin.
• - Constructional design in such a way that low lying Procurement costs offer the advantages of a large Number of interested parties with different weights how different size and / or figure accessible do.

The invention is therefore based on the object of a lie to provide a system in which, starting from the features described in the leading position, which increase manufacturing costs  Lich reduced, the organizational handling of the Be significant position for a specific person fold and a fine-tuning correction regarding the by adding components to the springs we achieved based on experience gained without manual work che activity can be carried out with a few simple steps.

This object is achieved in that the adjusting height of the springs is influenced by at least one horizontally into one in the cross-system direction Spring core inserted additional weight and / or by min at least one in the cross-system direction on a spring core applied flexurally elastic force distribution element.

The bodies coming into contact with the mattress lying surface one in different postures on the Lying system resting person both point outwards bulging, convex as well as lying back to the Part additionally concave areas.

Convex areas to be particularly noted are on their back the buttocks, but to a lesser extent also the calves. At on Taking the lateral position are convex areas in particular Hip and shoulders. Towards a defective Un support particularly sensitive concave area at both The back and the side is the area of the loins vertebrae and the waist and to a small extent the opposite area of the thighs relatively back from the buttocks, connected to the hip and knee joints and  can therefore act on these two joint areas. When taking postures between a clear Supine and lateral position are the differences from convex as well as concave and back areas of the body the mattress lying surface changed, but in principle with an identical tendency.

Now a mattress contains a spring core that extends out composed of individual springs, their relation of heights reduction and increase in support force coincides, so is unavoidable that concave body zones, especially the sen flexible lumbar vertebra and also the waist area, only one be supported legally, which inevitably Sagging down the vertebrae there sets that is visually hardly or not at all recognizable, but is still there.

A very simple way of doing this unsatisfactory behavior one homogeneous in terms of its feathers and therefore To eliminate inexpensive innerspring, is inventive according to it, in the cross-system direction horizontal additional weights with a length approximately corresponding to the system width in insert the innerspring where it is in use system height reduction of the respective Spring rows easier and thus must be enlarged to a convex body zone bulge, esp especially that of the buttocks area, in supine and lateral position to allow a sinking depth corresponding to the bulge chen.  

The concave adjacent to the buttocks or opposite the Ge This gives gels to the back of the body opportunity, according to their body weight percentage the under to compress the springs located more so that there the support strength increases and one to tension leading sagging of these body zones until compliance of the respective tolerance range reduced or completely ver is prevented.

A supportive influence of the body zones adapted in System transverse direction arranged rows of springs of a spring According to the invention, kernel can be used instead of or in addition to Insertion of weights also brought about by who that that below concave and / or past body per zones on the spring rows present there are flexible Force distribution elements with a length correspond approximately depending on the system width or in the area of the upper one Spring ends are easily detachable. This will each above a force distribution element body weight percentage, z. B. the areas of Lumbar vertebrae, waist and thighs, not from finally vertically down to those located there Feathers passed on, but more or less depending on the preselected elastic behavior of the force distribution element on both sides on more springs than As a result of the partial parallel connection that occurs Feathers spread out, causing the one to each one involved, below a force distribution element the amount of weight in the springs is reduced,  and the height that arises in this area reduction of the springs and the sinking depth of the corresponding body zones is reduced accordingly. A Sagging the be above the force distribution elements sensitive concave or against the body contour standing body zones become even in this way if restricted within tolerable limits or prevented.

The number and cross-section of the additional weights is determined chosen according to the desired sinking depth. An additional weight can e.g. B. from flat iron with a cross cut from z. B. 50 × 8 mm, the dimensions of the Springs and the cross section of the additional weights so on each other which are coordinated that with normal use of the Liegesy stems not the elastic behavior of the springs is limited.

In contrast, a force distribution element consists of approx. 0.5 mm thick and z. B. about 40 mm wide spring steel or fiber-reinforced plastic strap. The preference of Ver Use of elastic bands for the Kraftver dividing elements compared to z. B. round, flexible Components result from the fact that tapes are without the Interfering influence of the mattress base level of the system Have height requirements integrated above the innerspring where The power transmission takes place without selective Stress on parts of the innerspring, which affects the Usability of the system has a beneficial effect.  

In addition, the flexible behavior of Bands of the same thickness depending on the chosen one Bandwidth can be varied in a very simple way. The The task is therefore also solved in that a spring core exclusively elastic bands be placed, their respective width and placement according to the weight, the weight distribution and the Figure of the person using the system is coordinated.

A particularly advantageous variant of the Erfin manure is that two spring cores with relatively small ger height one above the other and one or more additional weights in the area of the lower spring core pushed and / or one or more power distribution elements elements are placed between the two spring cores. At As expected, this solution has evolved empirically during the course carried out comparative investigations show that for the top mattress layer that is required e.g. B. made of foam and textile materials Edition can be chosen a lower height than this the case would be if only a single spring washer position of the bed system is used.

The prerequisites for a sufficient, adjustable Air exchange in the area of the body surface on the System resting person to avoid water film formation according to the invention are brought about on the skin by that the wrapping of the innerspring on the underside has the area which favors air exchange. The Wrapping is there for. B. from particularly air-permeable  Material or as an open area, i.e. an area without Wrapping material executed. In addition, the one below is provided support plate with openings, the free Cross sections for the passage of air by means of a ver sliding, arranged below the support plate, even if plate is provided with openings by hand can be changed. Because the space inside the spring does not hinder air flow and distribution, is achievable in the manner described above that ever according to the temperature in the area around the bed system Help of changeable breakthroughs at higher levels temperature of air exchange increased and at low temperatures can be reduced. So it will not only the air exchange in the lying system favors, but also adapt the air exchange seasonal changes in the ambient temperature door enables.

The invention is based on drawings he purifies. Show it:

Figures 10a and 10b an additional weight specially designed for the shoulder area in two views.

Fig. 11a, Fig. 11b and Fig. 11c is a supporting plate in three views with ver modifiable openings for air exchange.

From Fig. 1 the basic outline of the body contour of a person can be seen in a lateral position. The neck area H, the shoulder area S, the lumbar region L and the buttock area G as well as the center distance D between the neck and the lumbar area as well as the body length KL and a tangent T applied to the underside of the outline are particularly identified.

FIG underneath. 2 shows the basic Umrißverlauf of a person's body figure same body length and center distance D, however, in the supine position. The area W of the calves is also marked.

From the comparison of FIGS . 1 and 2, light shows with the help of the horizontal tangent T provided below the body contour that a convex curvature of the body contour in the buttocks area G both in the lateral and supine positions is approximately the same Place located within the body's longitudinal extension. Therefore, if an additional weight is inserted below the buttocks area G in the innerspring and / or a force distribution element is placed on the innerspring area L below the lumbar vertebrae L, the particularly sensitive lumbar vertebrae area is adequately supported in the back as well as in side position so that a partial, from the spine especially in older people often only little tolerable sagging of the lumbar vertebrae is limited or prevented.

The frame 1, one of the two support members 2 and the adjacent support plates 3, 3 a of the support device 2, 3, 3 a are shown in Fig. 3. The support plate 3 is shown in more detail in FIGS. 7a and 7b, the supporting plate 3 a differs from the support plate 3 by additional devices for air exchange and is more accurate is provided in FIGS. 11a, 11b and 11c. A spring core 4 is placed thereon, the sheathing of which is not shown. In the illustrated example, the additional weights 6 a, 6 b and 6 c, whose position is matched to the body contour of the person shown in FIGS. 1 and 2, are inserted into the spring core. The two additional weights 6 a are placed below the buttocks area G, the additional weight 6 b below the calf area W and the additional weight 6 c below the shoulder area S. The additional weights 6 a and 6 b are z. B. simple flat iron, while the additional weight 6 c has a special shape, which is shown in Fig. 10. On the spring core 4 are in the drawn example in the system transverse direction a Kraftver distribution element 7 a below the lumbar region L and a force distribution element 7 b below the thighs. The mattress layer 5 is deposited above the innerspring 4 shown without an envelope.

The outline shown in FIG. 4 of a person in a supine position shows a type of figure in which the center difference D between the cervical region H and the lumbar region L is less than in the body outline representation in FIG. 2, the total body length KL being the same as in FIG . 2.

Fig. 5 shows a longitudinal section through the reclining system as Fig. 3, but with the difference that the spring core is composed of two individual spring cores 4 a and 4 b placed on top of each other. Again, a wrapping of the innersprings is not indicated. For the presentation, it was assumed that additional weights are not required. On the innerspring 4 a are placed in the illustrated case of the game, therefore, only the force distribution elements 7 a and 7 b, the positioning of these parts being carried out to match the body figure shown in FIG. 4. The differences in the placement with respect to the longitudinal extent of the lying system compared to the analog force distribution elements in Fig. 3 can be seen by comparison and illustrate the easily feasible adaptability of the effective force distribution of the lying system according to the invention to different body figures.

From Fig. 6, the frame 1 with the Abstützvorrich device 2 , 3 can be seen, consisting of two support elements 2 and adjacent in the system transverse direction side by side angeord Neten support plates 3rd The spring core 4 is placed on the support plates, again without showing its casing. Additional weights 6 are inserted into the spring core 4 , and force distribution elements 7 are placed on the spring core. A z. B. possible spatial location of the additional weights and force distribution elements can be seen from Fig. 3. Stored above the spring core is the z. B. from a fabric covered and z. B. foam material existing mattress layer 5 .

. Figs. 7a and 7b show an embodiment of the support plate 3, the supporting device 2, 3 in two Ansich th Such support plates are normally ge wooden customized, have a length corresponding to the system width and the support plates are self - adjusted to each z. B. two rows of springs of the spring core - about 140 mm wide and z. B. 20 mm thick. Each support plate is equipped with four spacers 8 in the example shown, so that adjacent support plates between them a z. B. 20 mm wide air gap, the width of which is kept constant by the mutual contact of adjacent spacers.

In Fig. 8a and 8b are a z. B. made from a flat iron additional weight 6 in two views Darge. Cross sections of the additional weights that deviate from the illustration can, for. B. have an obtuse angle or a slight curvature.

Figs. 9a and 9b show a flexurally elastic force distributing element 7 in two views, for the width b. B. is about 50 mm if the height reduction of the spring core which is set in the region of its position is to be greatly reduced, and its width b z. B. is 25 mm if the height reduction should be reduced less. Is clearly visible from Fig. 9b, the small thickness d as a prerequisite for the desired Biegeela sticity, which in the case of the manufacture of the Kraftvertei development element from spring steel z. B. is about 0.5 mm.

In FIGS. 10a and 10b, a Zusatzge is weight 6 c, which as shown is provided in Fig. 3 for insertion in a spring core in the shoulder region S. In this case, there are two externally placed Flachei senstücke 9 connected by a relatively light round rods 10. By means of the special design of this additional weight it is achieved that the sinking depth below the shoulder is preferably increased in the lateral position of the person using the system as a result of an increase in the height reduction of the spring core by the weight of the flat iron pieces 9 .

FIGS. 11a, 11b and 11c show the support plate 3 a in three views, with Fig. 11a is a longitudinal section along the line XIa-XIa in Fig. 11c. In the example shown, the support plate 3 a three Publ voltages is provided. 11 Another plate 12 has three openings Publ 14 and is slidably arranged by means of the two-sided Hal teschienen 13 under the plate 3 a. With the help of the handle 15 , the openings 14 can be placed so that the openings 11 open, partially ge opens or are completely closed.

Regardless of adding additional weights and / or Force distribution elements are the wire thickness and the Fe the winding diameter of the springs of the spring cores roughly the quotient of body weight in kg to body length in cm Voted. For people with a ratio of body weight for body length above about 0.5 kg / cm Wire gauge z. B. instead of 1.7 mm in diameter ser from z. B. 1.9 mm selected.

If 2 spring cores are arranged one above the other, you can depending on the requirements of the later user of a system in terms of the size of the emerging Sink depths or "mattress hardness" also two spring cores come to use, of which a z. B. made of wire a diameter of 1.7 mm and the other to B. from one Wire with a diameter of 1.9 mm is produced. If you choose egg  Such a combination then also offers the possibility by turning over the two different spring cores existing partial mattress a change of the To bring mattress hardness.

A way of an above average heavy waiter body with a quotient above approx. 0.5 kg / cm correspond, is below the torso in System transverse direction additional, relatively wide power distribution placement elements and then the fi support force distribution that becomes effective in relation to the gur by Un to realize differences in the width of the elements.

To the elastic behavior of the springs in the area of a closed Additional weights can also be used to secure the set weight also with at least one horizontal, transverse to its longitudinal direction provided joint.

The risk of noise as a result of loading contact between springs and additional weights or Force distribution elements can be eliminated that the added components with a non-metallic provided wrapping, the z. B. from a textile Fabric can be made.

For a subsequent fine adjustment of the support force distribution within the mattress due to exposed Experiences and / or regeneration of the Spine without manual work and without tools  To be able to make in a short time, it is advantageous to or the two innerspring of the mattress separated from the envelop the mattress overlay. The order envelope of the or the two spring cores is then z. B. executed so that the upper part of the envelope after opening tion of a separator, for. B. a tear or Velcro closure, foldable upwards or completely removable is. Then there is a simple way speed, the position of existing additional weights and / or Change power distribution elements or these against others exchange or change their number.

Because a successful use of the lying system ahead places the person resting on it in about one position of the head in the supine and lateral position, which the by adding additional weights and / or Force distribution elements becoming effective support force ver the pillow should be chosen not just the neck area and the head in a suitable way support, but also in relation to the longitudinal Fix the stretch of the lying surface.
