Description

"Seat, mattress or the like."

for the various types of known support devices are musty bent from wavy steel wire

"Ordering leathers for mattresses, beds or beds of ass used·

Here are such leathers according to Figure 1 in the Spread out in the direction of the arrow and fastened with their ends between the mattress edges.

Sdbhe leathers, however, have numerous drawbacks afflicted. Especially when they sleep two people When mattresses are attached, it is often necessary to reinforce them in the middle rope of the mattress, which is caused by Arrangement of further leather or in a similar manner. can follow.

The invention relates to such a support arrangement by means of leather in a new type of training, in which a lowering

of the mattress, especially in its middle part too is then avoided if the same is occupied by 2 people

The invention accordingly relates to a resilient support * - • and clamping device for seats, mattresses and the like characterized in that the middle part of this leather, e.g. shaped in an arc of a circle, has an area contains, in which the curvature is different from the curvature of the areas located at the ends of the springs is. Such training has the advantage that; 3 noble Deformation in the central part of the mattress under the action of the weight of the user can be avoided can"

The invention relates in the same way to the seats, mattresses and similar items, däie with one or several springs or are provided with a resilient device in a design according to the invention · In the accompanying drawings are, for example, invention shown according to designed springs.

While Figure 1, as mentioned above, illustrates a spring of known design, Figure 2 does not show one under tension, designed according to the invention Feather"

Figure 3 shows the same spring as Figure 2, but as Support device stretched between the sides of a mattress «

A leather according to the invention according to ligur 2, which can for example consist of a wave-shaped steel wire, has an approximately circularly curved central part 1 in each lobe. This middle circle continues in the end parts 2 and 3 of the leather also with arcuate curvatures. However, the radius of curvature of these end parts 2 and 3 is much larger than the radius of curvature of the central part 1 of the leather.

The gate part of this embodiment is a support spring in ligur 3 illustrates which leathers according to ügur2 shows in its supporting function stretched between the side surfaces 4 of a mattress

In the process, as can be seen from Ligur 3, "a." Bulge or bulge in the middle part 1 of the leather, which serves to create an undesirable depression this central part 1 to compensate for the higher weight load, ζ · Β · by 2 people, themselves could adjust. It is achieved by "using such tensioned support springs designed according to the invention to avoid any undesirable deformation of the mattress under stress when using leather known form of training would be inevitable.

The practice of the invention is not limited to shown schematically in the drawing as well as Examples described above are restricted to »instead of of a mattress or a couch, the leather designed according to the invention could also be used for seating or ideges Devices of a different kind, e.g. the fixed ones or removable cushions from armchairs or benches, sofas and the like.
