Description

The invention relates to a mattress with spring core or cushion core to relieve the heavy parts of the body, the spring core consisting of interconnected cylindrical springs with a uniform winding diameter or double-conical spiral springs with a stepped change in winding diameter or shaped springs with a square grid at the top and bottom and above and below the Springs each have a cover plate, and wherein the cushion core is provided with upper and lower cavities and is covered by an upper and lower cover plate, wherein in the cavities of the springs or the cushion core and / or in the interspaces of the springs in each case corresponding cylinder, cuboid - or double-conical profile body with different pressure effect are used at different points on the mattress and the profile body with the upper and / or lower horizontal spring coil run out, have about the same height and on the top and bottom of the cover plates nudge.

Such a mattress with spring core is known from DE-PS 25 38 725.

Due to the integrated profile body of different pressure intensity, the well-known construction serves as an orthopedic mattress, in which the body is anatomically correctly supported both in the back and in the side position according to the support weight and in particular in the spine area during rest and sleep phases an optimal relaxation of the muscles and Regeneration of the intervertebral discs is achieved, which relieves the cardiovascular system.

The disadvantage of the spring mattress is that it has a high weight due to the spring core and the integrated profile body and is therefore difficult to handle. Another disadvantage is that the profile bodies are detachably connected to the covering material by means of push buttons, ball head holders or the like and for this reason with a particularly strong cover and padding must be provided so that you do not feel the hard push buttons and the ball head holder through the padding.

In the mattress mentioned, the body is supported anatomically correctly in the side, back and stomach position, because one starts from the supine position when calculating the combined pressure effect, so that in the side position with approximately twice the sinking depth and half the contact surface, the same body contour and healthy support is provided. The combined pressure effect in the back, side and stomach position works simultaneously. However, since in addition to the above-mentioned positions there are also intermediate sleep positions in which the legs and arms lie offset, these limbs lying alone are supported too strongly. This can result in poor circulation and cramps.

A similarly constructed mattress, but instead of a spring core with a cushion core and instead of the profile body with coil springs in recesses, is known from US-A-3,310,819.

Because the profile body in the spring mattress mentioned within the spring washers or within the spring spaces in the area of the entire height of the spring core close to the springs for reasons of stability, there is the disadvantage that the profile bodies can be damaged by friction on the springs during sleep movements. In addition, the transverse to the lying direction and protruding from the innerspring profile body in the individual bed zones of different pressure effect, are not closed, so that the profile body can be felt in an uncomfortable way while sleeping. For this reason, the covering material must be much stronger for the winter and summer side.

The mattress according to US-A-3,310,819 has the disadvantage that the springs arranged in the recesses of the cushion core damage and hollow out the cushion core during sleep movements. Since the springs used can differ in their pressure effect from the vertical direction, such a mattress has a floating, unstable contact surface, which greatly reduces the lying quality.

The invention is therefore based on the object of providing a mattress in which the spring core is reduced in terms of its overall height and its weight, emphasis being placed on optimum lying quality.

This object is achieved in that the profile body with respect to the spring core or the cushion core up to the lower and upper cover plate or only up to the upper cover plate. Have an overhang and that the springs of the spring core at a distance corresponding to the overhang from the lower and upper or are only attached to the profile bodies from the upper cover plate.

Further developments of the invention are contained in the dependent claims.

Through the invention, a mattress is obtained in the construction, in which the respective suspension acts individually or in combination in its pressure effect directly on the supporting surface of the body, so that an optimally adjustable all-point counter-pressure suspension is created and the spring core structure is kept optimally low and on the use of push buttons and ball head mounts or the like. can be dispensed with.

The pressure elements have upper and lower vertical incisions 7 and 8, in which the spring connecting wire 2 rests in horizontal recesses 9 and 10. The distance between the incisions and thus the upper edges of the springs from an upper or lower cover plate 16, 17 corresponds to the height of the protrusion.

The profile pressure elements 4 are stabilized and guided by the connecting wire at the top and bottom. The edge seal is formed by the profile pressure elements with a rectangular cross section 11 with different pressure intensities 11A, 11B, 11C, 11D, 11E and 11F. They have an upper and lower projection 12 and 13 and an upper and lower horizontal cut 14 and 15. The vertical incisions 7 and 8 are additionally glued to one another, as a result of which the profile bodies are guided securely in the space between the springs. Summer and winter upholstery 18 and 19 with pricking and cover 20 and 21 rests on the upper and lower cover plates 16, 17.

4, the profile pressure element 4 can be seen enlarged with the upper and lower projections 5 and 6, the vertical incisions 7 and 8 and the horizontal recesses 9 and 10 for the connecting wire.

5 shows an enlargement of the edge termination profile with upper and lower horizontal incisions 14 and 15, in which the edge wire 3 is glued. In addition, the upper and lower projections 12 and 13 can be seen.

6 to 9 show a spring core made of shaped springs with a top and bottom square grid 23, the upper and lower spring connecting wires 24 and 25, and the upper and lower straight spring core outlet 26 and 27. In the recesses between the springs rest the rectangular in cross section Profile pressure body 28 with different pressure intensities 28A, 28B, 28C, 28D and 28E. The upper projection 29 of the rectangular profile pressure body has a vertical incision 30, in which the straight upper spring outlet 26 engages. After inserting the profile pressure element, the vertical incision is closed by gluing. The edge end profile pressure body 31 can be seen in FIG. 7 with the pressure intensities 31A, 31B, 31C, 31D, 31E. In addition, you can see the upper projection of the edge end profile pressure body 31 with the upper vertical incision. The profile pressure body 28 are placed on the lower spring connecting wire 25.

In Fig. 8 you can see the edge end profile pressure body 31 with the protrusion 32 and a vertical incision 33, while in Fig. 9 the rectangular cross-section profile pressure body with one-sided upper protrusion 29 and an upper vertical incision 30 can be seen, in which the upper straight spring core outlet rests. This mattress version has a very low height and is particularly suitable for camping and folding beds.

10-13 you can see a spring core 23 with a top and bottom square grid, the upper and lower spring connecting wire 24, 25, the upper and lower straight spring core outlet 26, 27, the profile pressure bodies 34, which are rectangular in cross section and have a projection 35, 40 on both sides and various pressure intensities 34A, 34B, 34C, 34D, an upper first and second vertical cut 36, 37, an upper first and second horizontal cut 38, 39, a lower first and second vertical cut 41, 42, a lower first and second horizontal cut 43, 44 , and the edge end profile pressure body 45, which has an upper and lower projection 46, 48 with upper and lower horizontal notch 47, 49.

Both profile pressure elements 34, 45 are shown enlarged in FIGS. 12 and 13 and it can be seen that in the profile pressure element 34 the vertical incisions with the horizontal recesses are arranged offset above and below. This version is particularly suitable for heavy people, because the profile pressure elements are arranged particularly close together in this spring system, so that there is an optimal support surface transverse to the lying direction.

14 to 16 show a spring core 50 made of cylindrical springs with a uniform winding diameter and the upper and lower retaining wire connections 51, 52 with the edge wire 53. The cylindrical profile pressure bodies 54 with different pressure intensities 54A to 54E are inserted into the interior of the cylindrical springs and point out an upper and lower projection 55, 56. The profile pressure elements of different pressure intensities are mutually connected by upper and lower elastic connectors 57, 58 by gluing, whereby the profile pressure elements are stably guided and secured against slipping. The connectors have different pressure intensities 57A to 57E and 58A to 58E. The edge termination profile 59 has a rectangular shape in cross section and has upper and lower projections 60, 61 and upper and lower horizontal incisions 62, 63, in which the edge wire engages and is connected to the incision points by gluing. This mattress is particularly flexible and is recommended for circulatory and venous diseases and similar complaints.

17 and 18 show the ready-made mattress, the cover 78 of which is held together by a separable zipper 79.

From FIG. 19 it can be seen that upper and lower cushion bodies 67 with recesses or cavities 8 ₀ , which run transversely to the lying direction, are arranged under and above a central pressure distribution plate 68. In these recesses, releasable profile bodies 66 with the same height, but different pressure intensities, rest transversely to the lying direction. These have a projection 71 relative to the upper and lower non-recessed plane of the cushion body 67. The profile bodies 66 are covered at the top and bottom by a pressure distribution plate 64, 65, so that ventilation channels 72 are formed. Upholstery ends are arranged on the pressure distribution plates. These have different cushioning materials, so that they are suitable on the one hand as a summer side 73 for the warmer days and on the other hand as a winter side 74 for the colder days.

Overall, the same elastic pressure properties are achieved in this structural structure by the same cushion bodies both for the winter side and for the summer side, i.e. in the supine position, the body is supported anatomically correctly in terms of its body size and body weight by the projections 71 with different pressure intensities, while in the side position where the same body weight presses on half the surface, the counterpressure effect results from the properties of the profile body 66 and the upper and lower upholstery 67 composed. The ventilation channels prevent heat build-up and make the mattress breathable. Moisture generated by perspiration is discharged to the outside via the side floor vents. By opening the zipper, the profile body can be easily replaced when the weight changes and adapted to the new conditions. This embodiment is particularly suitable for medium body weights.

20 and 21 with detail "D" show a second variant in which the profile body 6 6 are arranged offset and mutually when changing from the back to the side position on the pressure distribution. supplement plate 68 in the pressure effect. In the supine position, the body weight in the individual lying zones is carried by the protrusions of the profile body 66 and supported anatomically. In the loaded state, the height of the profile body 66 adjusts to the level of the cushion body 67. In the lateral position, however, the same body weight lies on approximately half the surface, whereby the profile bodies, which are alternately arranged at the top and bottom, are activated one after the other so that they anatomically support twice the body load. This embodiment is therefore particularly suitable for heavy people.

22 and 23 with detail "E", and 24 and 25 with detail "F" show a structural structure in connection with a spring core or with a cushion core made of polyether foam or foam rubber. As a result of this measure, the orthopedic mattress has on one side anatomically correct all-point support through the profile body of different pressure intensity, which is arranged on the upper side on the spring core 76 or poly ether foam or foam rubber core 75 via a pressure distribution plate 77 and a cushion body 67, the transverse recesses 80 has, in which the profile bodies 66 are detachably integrated with projections 71 of different pressure intensity. Ventilation channels 72 are formed between the profile bodies 66 and the upper pressure compensation plate 16. The padding on the summer or winter side is arranged above the pressure compensation plate 16. The combination with a spring core or polyether foam or foam rubber has the advantage that orthopedic mattresses for certain average sizes and body weights can be made available to the accommodation industry, while on the other hand a normal mattress is formed for other body weights and sizes.

In a further variant according to FIGS. 26 and 27, which is particularly suitable for couches with bed frames that also serve as seating furniture, only a low overall height makes sense in order to achieve a sufficient bed box volume on the one hand and a normal seat height on the other. This variant has the advantage that when the mattress is used as a bed, it can be equipped with integral suspension according to body weight and height, so that the body lies supine on the protrusions of angular pressure bodies 81 depending on the contact pressure with different pressure intensities, e.g. 82.1 to 82.5 , is supported by an upper padding serving as bed side upholstery 69, recesses 83 and an upholstery cover 73, 74 with upholstery cover 84, 85 and the cover 78 is anatomically correct. If the body rotates into the side position, the profile body protrusions 71 are compressed approximately on half the support surface in accordance with the contact pressure at the level of the ventilation ducts 72, so that the same body weight is now from the profile bodies 66 in the respective support zone via the bed side upholstery 69, the recesses 83, the upper upholstery end 73, designed as a winter or summer side, and the upper upholstery cover 84 on a lower upholstery serving as seat side upholstery 70 with a lower upholstery end 74, designed as a winter or summer side, the lower upholstery cover 85 and the cover 78 are also anatomically correctly supported becomes. If the mattress is to be used as a seat upholstery, which only requires selective stress and therefore firm upholstery, it is rotated by 180 °. This results in firm and stable elastic seat upholstery. The angular design of the profile pressure element has the further advantage that, during the transition from the back to the side position, the support takes place continuously in the same pressure progression because the vertical and horizontal legs are homogeneous. It is also advantageous that the profile bodies in the cutouts 83 can be inserted and replaced without problems by opening the side zip 79.
