Mattress, provided with spring elements, such as coil springs
The present invention relates to a mattress ( 10 ), for use as a bed, which mattress comprises substantially resilient material such as a foam rubber, spring devices ( 4 ) such as coil springs being provided in the mattress, in order to distribute the pressure exerted upon the mattress. The mattress according to the invention is characterised in that the mattress comprises at least two layers ( 1,2 ) placed one on top of the other, blind holes ( 3 ) for the accommodation of the spring devices ( 4 ) being made in at least one of said two layers, which blind holes connect to the boundary face between the two layers.
1. A mattress for use as a bed, the mattress comprising resilient material, spring devices provided in the mattress to distribute pressure exerted upon the mattress, at least two layers placed one on top of the other, blind holes for the accommodation of the spring devices in at least one of said two layers, the blind holes extending through said at least one layer to the boundary between said one layer and another of said at least two layers, wherein each said spring device comprises a coil spring element, a shock absorber operatively connected to said coil spring element and a disc-shaped end element on the end of the coil spring element.
2. Mattress according to claim 1 , wherein said shock absorber is in the form of a substantially continuous element of resilient material.
3. Mattress according to claim 1 , wherein said shock absorber comprises polyether.
4. Mattress according to claim 1 , wherein said shock absorber comprises a rubber element.
5. Mattress according to claim 1 , wherein said shock absorber comprises an air cylinder.
6. Mattress according to claim 5 , wherein said spring devices are distributed over the mattress, the spring characteristic of the springs varying along the length of the mattress.
7. Mattress according to claim 6 , wherein said first layer comprises a first material and the second layer comprises a second material, the first material and the second material differing from each other.
8. Mattress according to claim 1 , wherein at least one of the layers comprises slow foam.
9. Mattress according to claim 8 , having notches made in the slow foam on the outside of the mattress, which notches extend in one or both of the longitudinal direction or the traverse direction of the mattress.
10. Mattress according to claim 9 , notches extend along a length of approximately 40 mm.
11. Mattress according to claim 1 , wherein at least one of the layers comprises polyester.
12. A mattress according to claim 1 wherein the coil spring element has two ends and each spring device includes a disc-shaped end element for each end of the coil spring element, the coil spring element being fixed at each end to a respective one of the disc-shaped end elements.
13. Mattress according to claim 12 , wherein each said shock absorber is fixed at both ends to the end elements of the spring devices.
14. Mattress according to claim 13 , wherein said shock absorber is hingedly connected to at least one of the end elements of the spring devices.
15. Mattress according to claim 1 , wherein the spring characteristic of the shock absorber varies along the length of the mattress.
16. A mattress according to claim 1 wherein each end element is pivotally attached to a respective shock absorber.
17. A mattress according to claim 16 wherein the pivotal attachment of each end element to a respective shock absorber is effected by a snap closure and the end element is pivotable about the snap closure.
18. Method for producing a mattress, for use as a bed, the mattress being made of resilient material, and spring devices being fitted in the mattress, in order to distribute the pressure exerted upon the mattress, wherein said mattress is constructed of at least two layers placed one on top of the other, blind holes being made in at least one of the layers, wherein each said spring device comprises a coil spring element, a shock absorber operatively connected to said coil spring element and a disc-shaped end element on the end of the coil spring element and wherein said spring devices are provided in said blind holes, after which said blind holes are covered by a second layer of the mattress.
19. Mattress according to claim 18 , wherein blind holes are provided in both a first and a second layer of the mattress, and spring devices are subsequently provided in the blind holes of the first layer of the mattress, the spring devices then being covered by the second layer of the mattress, so that the blind holes of the first layer of the mattress lie in line with the blind holes of the second layer of the mattress.
20. A mattress for use as a bed, the mattress comprising resilient material, spring devices provided in the mattress to distribute pressure exerted upon the mattress, at least two layers placed one on top of the other, blind holes for the accommodation of the spring devices in at least one of said two layers, the blind holes extending through said at least one layer to the boundary between said one layer and another of said at least two layers, wherein said spring devices each comprise a coil spring element and a shock absorber operatively connected to said coil spring element and wherein the shock absorber comprises an air cylinder.
