Description

The invention relates to a mattress with a spring core to relieve the heavy parts of the body, the spring core consisting of interconnected cylindrical springs with a uniform coil diameter or double-conical spiral springs with a stepped change in coil diameter or shaped springs with a square grid at the top and bottom and above and below the springs each has a cover plate and in the cavities of the springs and / or in the spaces between the springs, corresponding cylindrical, cuboid or double-cone-shaped profile bodies with different pressure effects are inserted at different locations on the mattress and the profile bodies with the upper and / or lower horizontal spring coil run out , have about the same height and bump against the top and bottom of the cover plates.

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

The disadvantage of this 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. For this reason, they have to be provided with a particularly strong cover and padding so that the hard push buttons and the ball head holders are not covered by the Upholstery feels.

In the mattress mentioned, the body is supported anatomically 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 at about twice the sinking depth and half the contact area, the same body-appropriate and healthy Support is given. The combined pressure effect in the back, side and stomach position works simultaneously. But since there are also intermediate sleep positions in addition to the above-mentioned positions, in which the legs and arms lie offset, the limbs lying alone are supported too strongly. This can result in poor circulation and cramps.

The invention further relates to a mattress with a cushion core for relieving the heavy parts of the body, the cushion core being provided with upper and lower cavities and covered by an upper and lower cover plate, and wherein in the cavities of the cushion core in each case corresponding cylindrical or cuboidal profile bodies with different Pressure effect is used at different points on the mattress and the profile body have about the same height and bump against the top and bottom of the cover plates.

Such a mattress with a cushion core is known from an internal state of the art.

A similar construction is shown in CH-A-536616, which relates to a mattress with a cushion core, which consists of a base body made of soft foam, which has depressions on its upper contact surface, and the body is made of a harder material with a poorer thermal conductivity than the soft foam are embedded in such a way that it projects over these deposits. This cushion body is therefore made entirely of plastic and contains no metallic parts.

A similarly constructed mattress, but instead of the profile body with helical springs in recesses, is known from US-A-3 310 819.

This mattress has the disadvantage that the springs arranged in the recesses of the upholstery core damage and hollow out the upholstery core during sleep movements. Because this means that the springs used can differ in pressure from the vertical direction, such a mattress has a floating, unstable contact surface, which greatly reduces the lying quality.

The invention has for its object to develop the above-mentioned mattress with both cushion and spring core in such a way that the cushion or spring core is reduced in height and weight, with an emphasis on optimal lying quality.

This object is achieved according to the invention for a mattress with a spring core in that the profile bodies have an overhang relative to the spring core up to the upper and lower cover plate or only up to the upper cover plate and in that the springs of the spring core are at a distance corresponding to the projection from the lower and upper or are only attached to the profile bodies from the upper cover plate.

For a mattress with upholstery core, the solution to the problem according to the invention is that the profile bodies have a protrusion from the upholstery core up to the upper and lower cover plate or only up to the upper cover plate.

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.

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

1-5 show a spring core with double-conical spiral springs with a winding diameter 1 that can be varied in stages, a connecting wire 2, an edge wire or edge frame 3 and the profile pressure bodies 4 with a diamond-shaped cross section with different pressure intensities 4A, 4B, 4C, 4D, 4E and 4F, etc ., and an upper projection 5 and a lower projection 6. 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 closure is formed by the profile pressure elements with a rectangular cross section 11 with different pressure intensities 11 A, 11 B, 11 C, 11D, 11 E and 11 F. 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. On the upper and lower cover plate 16, 17 rests summer and winter upholstery 18 and 19 with pricking and cover 21 and 21. In addition, you can see the drill cover 22. In FIG. 4, the profile pressure element 4 is enlarged with the upper and lower overhang 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 31 A, 31 B, 31C, 31 D, 31 E. 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 pressure cross-section 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 with a rectangular cross section and 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, 35 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 Overlap 55, 56 on. The profile pressure elements of different pressure intensities are mutually connected by upper and lower elastic connectors 57, 58 by gluing, as a result of which 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 has a particularly high flexibility and is recommended for circulatory and vein 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 80, 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 body for both the winter side and for the summer side. H. 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 cushion bodies 67 is 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 bodies 66 are arranged offset and mutually complement one another in the pressure effect when changing from the back to the side position via the pressure distribution plate 68. 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 an upholstery core made of polyether foam or foam rubber. As a result of this measure, the orthopedic mattress has on one side an 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 polyether foam or foam rubber core 75 via a pressure distribution plate 77 and a cushion body 67 which has transverse recesses 80 , in which the profile bodies 66 are detachably integrated with projections 71 of different pressure intensities. 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 core 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 beds with bed frames that also serve as seating furniture, only a low overall height makes sense in order to achieve a sufficient bed frame volume on the one hand and a normal seat height on the other.

This variant has the advantage that it can be equipped with an integral suspension according to body weight and height when using the mattress as a bed, so that the body in the supine position on the protrusions of angular pressure bodies 81 depending on the contact pressure with different pressure intensities, for. B. 82.1 to 82.5, by an upper serving as bed side upholstery 69 padding, via recesses 83 and an upholstery cover 73, 74 with cushion cover 84, 85 and the cover 78 is anatomically correctly supported. If the body rotates into the lateral position, the profile body protrusions 71 are pressed together at about half the Aufiiegefifläche corresponding to the contact pressure at the level of the ventilation channels 72, so that now the same body important of the profile bodies 66 in the respective support zone over the bed side upholstery 69, the recesses 83, the upper upholstery end 73, 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, as Winter or summer side trained, the lower cushion cover 85 and the cover 78 is also supported anatomically correct. 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 body in the recesses 83 by opening the side zip 79 without problems. can be used and replaced.
