Slatted frames are often used as a springy base mattress. A distinction is made between two construction groups, one of which has the slats connected by cross bars to form a grate unit, while the other has the slats unified Support on the mattress frame. It is known both the cross bars of the first variant to be supported by springs on the bed frame as well as the ends of the individual slats of the second variant additional cushioning by springs on the mattress frame.

The invention relates to a resilient base mattress of the last mentioned type. You can It is true that significantly increasing the suspension comfort with such base mattresses, but this is countered by this Another problem that the springs should be supported against bending. To counteract this, Coaxial support spikes have been proposed for the springs. This has the disadvantage that with stronger When the springs are bent, the mandrels rest against their guide holes and thereby both the bend limit inelastic as well as be able to strongly dampen the spring action under friction. One loses so again part of the spring comfort.

In addition, metal parts are poorly tolerated in lying areas by many people, so that the This disadvantage is counteracted by the higher comfort brought about by the springs.

Metal-free spring elements are known which have advantages in terms of insulation, but they are unsuitable for the purposes of the invention.

The aim of the invention is to eliminate these inconveniences, and it thus relates to a resilient base mattress with a mattress frame and wooden slats, the ends of which are each supported on coil springs are arranged on the longitudinal legs of the mattress frame.

According to the invention it is therefore proposed that on the longitudinal legs of the mattress frame Foam bars are attached, which have vertical cavities in which the coil springs are embedded are.

For heavily used berths, e.g. B. for children's homes, it is an advantage if after a Embodiment of the invention in the middle of the base mattress one to the two longitudinal legs of the mattress frame arranged in parallel, covered with foam slat is provided on which in the event of excessive sagging, the slatted frame slats are elastically intercepted.

The foam bars in which the springs are embedded serve a dual purpose. she Spring base mattress

On the one hand, support the slat ends and springs under load, causing them to flex the springs counteract this and also have a shock-absorbing effect. On the other hand, they have an insulating and sound-absorbing effect.

The base mattress according to the invention is thus not only more comfortable than that in terms of suspension technology already known base mattresses, but is also health-wise due to the insulation of the metal springs and advantageous through noise reduction.

An embodiment of the invention is shown in the drawing.

F i g. 1 shows in its right half a section of the one attached to the longitudinal leg of the mattress Foam bar and in its left part a side view of the mattress seen from the outside; the The direction of view runs in both figures in FIG. 1 that is perpendicular to the longitudinal direction of the mattress and in the horizontal direction;

2 shows a cross section through the mattress with a vertical cross-sectional plane, which is perpendicular to the longitudinal direction of the mattress.

As far as it is shown in section in FIGS. 1 and 2, the mattress frame is denoted by 1, and the foam bars 2 are attached to the longitudinal legs of the mattress frame, which have vertical cavities 4 in which the 3 used to support the curved wooden slats Reach in coil springs 5.

When using the mattress, the wooden slats 3 bend, and especially the Coil springs 5 compressed. Simultaneously

Claims (2)

With the deflection of the wooden slats 3, the upper ends of the two helical springs in FIG. 2 shift outwards and then rest against the inner surfaces of the vertical cavities 4 in the foam bars, so that with a further shift of the upper ends of the helical springs S outwards too the elastic counterforces of the foam take effect. The flexibility of the mattress is based not only on the elasticity of the coil springs, but also on the elastic properties of the foam bars. F i g. 2 still shows a slat 6 which runs parallel to the two longitudinal legs of the mattress frame and is covered with foam in the middle of the mattress, which is also indicated by dotted lines in the side view shown in FIG. 1, left figure. This slat 6 is used to support the wooden slats 3 when they are completely bent. The foam bars and the foam covering of the slat 6 have the further advantage that they reduce the unwanted noises often occurring when using the known mattresses. Patent claims: 1. Spring-loaded base mattress with a mattress frame and wooden slats, the ends of each are supported on coil springs, which are arranged on the longitudinal legs of the mattress frame are characterized in that foam bars (2) are attached to the longitudinal legs of the mattress frame (1), which have vertical cavities (4) in which the coil springs (5) are embedded. 2. Resilient base mattress according to claim 1, characterized in that in the middle of the Lower mattress one to the two longitudinal legs of the mattress frame (1) arranged parallel, lath (6) covered with foam is provided.
