BRIEF SUMMARY
FIELD OF INVENTION
This invention relates to a slatted base for a bed with two longitudinal supports, spaced apart, running essentially in longitudinal direction of the bed, with a number of spring slats mutually spaced apart essentially in transverse direction with respect to the longitudinal supports, which collectively form a supporting surface for a mattress. Elastically deformable supporting slats situated lower with respect to the spring slats connect the spring slats with the longitudinal supports, the longitudinal supports being positioned below the spring slats and the outer sides of the longitudinal supports facing the ends of the spring slats being set back with respect to the spring slat ends. In each case, at least one spring slat and one supporting slat combine with two lateral edge-area elements to form a bearing module.
BACKGROUND OF THE INVENTION
A slatted base is disclosed in the European Patent Application EP 0 539 644. Shown therein are lower supporting elements, or respectively lower supporting slats, which are either firmly connected to the longitudinal supports or have a considerable degree of freedom at the places of connection to the longitudinal supports. It has been shown that the sleeping comfort achievable with the slatted base can be increased with specially designed supporting slats and with a corresponding fastening of the slots to the longitudinal supports. It is important for the lower supporting slat to have a certain elastic characteristic. It is also important to arrange the fastening of the supporting slats to the longitudinal supports in such a way that there is only a limited degree of freedom of the supporting slats with respect to the longitudinal supports.
Furthermore, the lateral connecting element, or the edge-area element as it will be denoted hereinafter, is of great significance. This edge-area element, which connects a lower supporting slat and one or more upper spring slats at each of their ends and combines them into a bearing module, is designed in such a way that a pivoting of each individual spring slat or a pivoting of all of the spring slats combined into a bearing module is possible transverse to the longitudinal direction of the longitudinal supports.
Resulting upon deflection of both the spring slats as well as the supporting slats are these longitudinal changes; these have to be compensated for, whether through the edge-area elements or the way of fastening the bearing module to the longitudinal supports.
With the present type of slatted bases, the longitudinal supports, which are hidden laterally below the spring slats, are not the dominating elements, which mark the appearance of the slatted base, but instead the edge-area elements, side by side in a row. So that the slatted base has an aesthetically appealing appearance, these edge-area elements should be as flat as possible, or respectively be constructed as low as possible, so that the lateral edge areas of the slatted base are finished off with a relatively slender line. Such a construction gives the viewer the impression of a freely suspended slatted base or bed.
SUMMARY OF THE INVENTION
It is the object of the present invention to create a slatted base, improved with respect to the state of the art.
The invention is an improvement in that the supporting slat has a central, elastically deformable area, situated between the longitudinal supports, which is more elastic than two end areas of the supporting slat directed from the longitudinal supports toward the spring slat ends. The supporting slat is supported on the two longitudinal supports and is held thereon with connecting elements. A pivoting movement of the supporting slat is possible at each supporting place in the transverse direction to the corresponding longitudinal support, wherein the pivoting movements have the effect that the two lateral edge areas of a bearing module, when loaded at any place, move from the support side downward.
The range of deflection of the spring slats in the middle of the slatted base is relatively
