Spring frame for beds

The invention relates to a spring frame for beds, consisting of a rigid support frame, one on Support frame fastened spring insert, one the Außenforrti the top of the spring frame determining upholstery on the spring insert and one attached to the support frame Relation.

In the case of spring frames of this type, the Padding attached to the spring insert is usually made of crushed foam, wadding or similar material, with the A protective blanket is often also placed on the upholstery. As a final measure, you take care of the cover of the spring frame to be stretched over the upholstery and nailed to the underside or inside of the frame, but it is for hotel beds, for example

It is important that a high standard of hygiene is maintained, and one has therefore in various ways tried to improve the construction of the spring frame.

The invention is based on the object of a spring frame to create whose cover can be easily removed and washed, and its upholstery in a high is designed in a manner that satisfies hygienic requirements.

According to the invention, this object is achieved by the combination solved that the padding consists of an elastic foam, in which at least the outer coil of the springs Spring insert is embedded, and that the cover is releasably attached to the • support frame by having strips on its edge is connected and by these strips together with the attached edge parts of the cover in the lower edge of the Frame formed, downwardly or inwardly directed grooves are introduced, with the cover stretched over the upholstery is.

With such a spring frame, the reference held taut by the spring insert and held by the strips inserted into the frame grooves; do the solving and to facilitate attachment of the bespoke cover, the strips attached to the edge of the cover preferably end just before the corners of the spring frame.

The invention is now described in more detail below with reference to the drawing. Show it:

1 shows the spring frame according to the invention in cross section, and

2 shows a part of the corner of the spring frame from below seen.

The spring frame shown in Fig. 1 has a support frame 1 with a solid base inserted therein, made of a possibly perforated disc or slats 2 or a bottom made of braided rubber strips. A feather insert 3 of conventional construction is attached to the floor 2. The padding 4 of the spring frame consists of a single one Layer of elastic foam that, when foaming is connected to at least the outer coil of the springs of the spring insert in such a way that it encloses them. The padding 4 can consist of e.g. a polyether or polyurethane foam that has been manufactured in a sufficient thickness, to serve as a single layer of padding on top of the spring insert. D-by connecting the foam to the springs the spring insert, the upholstery is properly anchored to the spring insert and possibly squeaking noises in the upper part of the Spring insert, where the different springs are connected to each other, are effectively prevented.

According to a preferred embodiment of the spring frame according to the invention, the lower ends of the Feathers of the spring insert in an elastic foam layer 5 embedded, which have been connected to the spring insert and possibly also to the solid base 2 during foaming is.

According to the invention, the support frame 1 has grooves 6 which either are directed downwards, as shown on the left in Fig. 1, or inwards towards the center of the spring frame are inverted, as shown on the right in FIG. The cover 7 of the spring frame is on its edge parts connected to strips 8, which are expediently made of plastic and glued to the cover and / or sewn to it are. These strips and the parts of the cover attached to them are then inserted into the grooves 6, so that the cover is releasably attached to the frame 1. The tailor-made cover is preferably of such a size that the spring insert 3 is weakly compressed when attaching the cover to the support frame 1. In a conventional manner, the spring frame be provided with foam inserts at its corners, that support the corners and keep the cover stretched within these parts.

As can be seen from Fig. 2, they end at the edge of the cover 7 fastened strips 8 preferably just before the corners of the

Spring frame. In this way, the loosening of the Relation made easier. In Fig. 2, the cover 7 and the strips 8 attached to it are illustrated by dash-dotted lines.

According to a particularly advantageous embodiment of the According to the invention, the cover consists of a laminated fabric, i.e. a Fabric with an elastic foam layer on the back is applied. This offers the advantage that the cover retains its shape more easily on the upper side of the padding 4 can.
