Resilient, resilient floor for furniture

The invention relates to a resiliently flexible floor for furniture, in particular for beds.

2s are already resilient floors for beds, Chairs and the like have been proposed, essentially several have parallel and rather rigid ribs resiliently suspended between a pair of frame members are. In one case, the resilient suspension of the ribs or slats consists of bands or rings made of rubber, which are attached to the ends of the ribs and to the frame elements with the aid of hooks or the like.

The furniture base described above is well suited per se, but it tends to be somewhat overloaded; Furthermore it is difficult to vary the deflection. Furthermore, the wear on the suspension is unnecessarily great.

The object of the invention is to overcome these disadvantages. avoid; for this purpose, the furniture floor according to the invention is essentially characterized in that each resilient suspension in combination an elastically stretchable element and one or two inelastic elements pivoted in most or all m possible load conditions, one between the frame element and the associated rib or slat are arranged one after the other.

The furniture floor according to the invention has the advantage that it bends easily in response to small loads and at the same time withstands large loads without impermissible deflection. In addition, the furniture floor can be easily can be adapted to numerous requirements.

™ To on the one hand a softer spring effect and on the other hand to create a guarantee against overload at the same time, the furniture floor according to the invention is preferably designed so that the suspension devices between the associated frame and a downwardly protruding arm, projection or the like. on the underside of each slat, the end portions of each slat being the adjacent frame side member overlap. This also ensures that

the friction and wear of the mattresses is reduced and that the floor has a more pleasant impression offers, as it is flexible up to the edge sections.

The invention is explained in more detail below erläu- reference to schematic drawings of several exemplary embodiments M. Show it

Fig. 1 shows an embodiment of a resilient one Suspension for a rib or lath;

. Fig. 2 on an enlarged scale, like the various Forces act when bending;

Fig. 3 shows an ideal bending profile for a bed base and

According to the drawings, a bed base can have a frame with two frame side elements Io, between which several ribs or slats 11 are suspended resiliently, preferably parallel to one another. The slats 11 are substantially rigid and can be made of wood, plastic or any other suitable material including metal. Each slat is resiliently suspended on each of its sides on the adjacent frame side element Io,

with the help of a general. labeled 12 Spring arrangement.

Each spring arrangement 12 has an elastic element 13, preferably formed by a rubber ring, and a (or 2) inelastic, pivotable element 1 * 1, which is preferably an at least "substantially closed metal wire hanger. The elastic element, that of simplicity is referred to in the following as a rubber ring 13, is on the frame side element Io with the aid of a bracket 15 attached, which can be fixed or pivotable and which in this case has two bent ends that are inserted into one in

the frame side member Io protrude slot 16 in which they are retained in an easily removable manner by means of a pair of pins 17 inserted from above. The pivotable bracket 1 * 1 is inserted into the rubber ring 13, with its legs reaching over the end of the slat 11 on which the bracket I ¹ J is pivotably held in an inclined slot 16 located on the underside of the slat. There are of course a number of other ways of attaching the rubber ring 1-3 to the frame side element and attaching the pivoting bracket I ² J to the slat 11 are conceivable.

2 shows that when the slat 11 is bent in the direction of arrow A, a tensile force is exerted on the rubber ring

is exercised. This tensile force can be divided into a vertically lifting component B and a horizontally pulling component C. be disassembled. When the rib 11 is bent downward, the angle y between the horizontal plane increases and the direction of arrow A and the stroke component B increases compared to the horizontal tension component C. The size of component B varies as a sine function of the ™

Force A according to the following formula:

B = A * sin y

This means that the stroke component B depending on the resistance of the elastic element (the rubber ring 13) and varies as a sine function of the size of the angle y.

The amount X of the deflection varies according to the formula: X = Z * tang y, '

where Z is the length of the spring assembly 12 in the unloaded condition. From this it follows that the size X of the deflection varies with Z and with the tangent of the angle y. ^ If the load remains the same, the deflection increases, when Z is increased. The size B grows rapidly with increasing values of the angle y, ao that the deflection spawns as desired ii large limits can thus be varied,

109830/0087

that the length of the spring assembly 12 and / or the resistance of the rubber ring 13 is varied.

The pivotable bracket 14 leads to the fact that the rubber ring .13 is only lengthened by a few millimeters with normal deflection, which in terms of the service life of the A rubber ring 13 is very beneficial. In addition, the pivotable bracket allows the rubber ring 13 to be short and strong to make, so that the spring arrangement takes up only a small amount of space. - '

Fig. 3 shows in general that 'by a large resistance against high loads and a weaker resistance against smaller loads a deflection profile for correct rest position is guaranteed; of course this weaker resistance is in the highest to ensure softness and comfort Dimensions desired.

Fig. 4 shows schematically in end view a bed base the afore-described version in detail. In the lower * 5 shows that the slats 11 in an overlapping manner Arrangement can be arranged; in this case the spring arrangements are between the outer edges of the frame side elements Io and arms 19 extending downward

the underside of the ends of the slats 11 arranged. In this embodiment, the floor bed extends into the edge sections yielding, v / obei the frame side elements Io act at all times as a carrier against overloading by the slats 11 place on the frame elements Io in the event of inadmissibly high loads.

In some areas of application, the battens can be comparatively wide, e.g. on the order of 15 up to 2o cm; in this case it may prove advantageous to have two or more spring assemblies 12 for each slat end to use. Other modifications and changes in detail can be made without the The scope of the appended claims is left.
