The embodiment of the slatted base according to the invention shown in FIG. 1 comprises a frame which has an outer cladding 6, longitudinal struts 1 and Cross struts 2 and 5 rests on the floor by means of feet, and one A large number of slats 3, which are arranged parallel to one another in the transverse direction are.

As can be seen from FIG. 2, the slats 3 are in particular at their end regions supported movably by vertical elements 4, wherein the vertical elements 4 on the slats 3 pivotally attached via pivot axes 12 and free vertically are movable and by guide elements attached to the frame 7 in their movement are performed, causing a "tilting" of the vertical elements 4 is prevented from the vertical. This means that the slats 3 can be moved guaranteed in a vertical direction V.

The pivotable connection of the vertical element 4 with the slat 3, as well in particular the rounded end 13 of the vertical element facing the slat 3 4 allow a pivoting movement S of the slat 3 about its longitudinal axis, whereby an advantageous adjustment of the orientation of the crossbar 3 to the body directly or indirectly lying on it is guaranteed.

The guide elements 7 in particular include rectangular plates, which in Longitudinal direction of the slatted frame are attached to the longitudinal beam 1, and recesses in the longitudinal beam 1, the rectangular plates e.g. by a Tongue and groove connection in the side member are firmly connected. The rectangular ones Plates are spaced from each other so that they have cavities or recesses 9 define which a free movement of the vertical elements 4th allow between the rectangular plates in a vertical direction V while a movement in a horizontal direction H, apart from a certain one Game is prohibited.

The vertical elements 4 are supported on an elastic band 14, which in turn by rockers 10 hinged to the frame, at least over partial areas is worn, the support of the vertical elements 4 on the belt 14 in particular by rollers 17, which are each rotatable on one of the Latte 3 facing away from the end of each vertical element 4 are provided.

The rockers 10 are on the particularly hollow longitudinal strut 1 Swivel axes 12 pivotally attached, which in corresponding recesses intervention.

The band 14 is in particular elastic and endless, being about in the longitudinal direction of the slatted frame is deflected at the front rockers 10, i.e. Volume 14 runs on the upper and lower side of the rockers 10 and is one Endless belt closed.

On the lower side of the frame 1 facing away from the slat is a variety of Lower support elements 8 are provided, which preferably the band 14 and / or support the rockers 10 in the vertical direction V when the band 14 and / or the rockers 10 by a predetermined load Latte 3 can be stretched or swung out of the rest position. So it becomes a Overstretching the band 14 prevented.

The support elements 8 in particular define recesses 9 ', which with the Vertical elements 4 are aligned or aligned, whereby a partial Penetration of the vertical elements 4 with the two arranged one above the other Band layers is made possible, which in particular increases the rigidity of the slatted frame is reached when a predetermined or predeterminable Load of the individual slats is reached.

In Fig. 3 is a different type of load on the slats 3, 3 'that in Fig. 2nd shown embodiment of the present invention.

Due to a higher load, the slat 3 'lowers more, which means the associated vertical element 4 'causes the band 14 in this Area is bent down more than in areas where e.g. the crossbar 3 and thus the vertical element 4 are less stressed. The stronger bend of the band 14 causes the rockers 10 to pivot in different ways be, the tension of the belt 14 above and balances below the rockers 10. The displacement of the band 14 in one Horizontal direction H is here by the rollers 17 of the vertical elements 4, 4 ' which facilitates the friction between the vertical elements 4, 4 'and Reduce volume 14.

In order to prevent the vertical elements 4, 4 'from being inadvertently lifted out, is a retaining device 15 in particular in the form of a through a bore 16 provided in the vertical element 4 guided wire. This wire, in particular made of nylon, is carried out in particular by all vertical elements 4, 4 ' and attached to the front vertical elements 4. The restraint 15 could, however, also be inserted into a recess in the vertical element Be pin, which rests on the underside of the guide element when the highest position of the vertical element is reached.

From Fig. 3 it can also be seen that the vertical element 4 in a recess 18 of the crossbar 3 engages, creating a safe and easy pivoting is made possible.

The vertical element 4 shown in Fig. 4 comprises a roller 17 which on a End is rotatably arranged in a recess 19, wherein the vertical element 4 has a smaller width at the end opposite the roller 17, to be received in a recess (not shown) of a slat (not shown) and to be pivotally attached to it.

In an embodiment not shown, vertical elements are also in one central area of the slats arranged, providing improved support the slats are provided.
