Foam cover for curtain rails

The innovation concerns foam panels for curtain rails, which can be connected to a narrow side of the curtain rail.

From the German utility model 7 ^ 2O 962 is a curtain rail known with aperture, which consists of a support body in which at least one downwardly open running channel for rolling or sliding hanger is provided, and one can be connected to a narrow side of the support body Aperture exists. The panel is equipped with rigid locking claws at opposite points and the cover itself has an area that can be bent in the transverse direction, through which the locking claws can be transferred in their effective ledges of the curtain rail

will

rear-reaching position enables /. The flexible areas of the screen can be formed by a groove, whose wall thickness tapers towards the center of the groove.

With such a diaphragm, the best "'is a basic requirement for the effectiveness of the attachment of the same to the curtain wall in that the panel after its bending in the Area of said groove returns to its original shape so that the opposing locking claws can take effect.

This known fastening principle is therefore not suitable in connection with foam panels, since they are made of foamed plastic existing panels have very poor suspension properties and are, so to speak, plastically deformable and already do not return to the starting position after a relatively small deformation.

It is also generally known to make the connection between the cover and the support body of the curtain rail with the help of projections, engage the holes adapted to them.

Finally, it is also known to equip the panels or the support body with resilient retaining claws, which then form parts of the support body or reach around the cover or snap it into existing receptacles.

In all of these known fastening constructions, the lateral fastening projections such as the resilient retaining claws exist, the rigid locking claws or fastening pins made of the material the panel itself or the material of the curtain cViene and are formed in one piece with this.

Because of the easily deformable and mechanically non-rigid and solid material in the case of foamed material strips, this has been the case up to now proceeded that you foam panels by gluing to a associated support body has attached a curtain rail what However, it is associated with disadvantages, since you always have one when producing a rail set with curtain rail and cover Have a suitable adhesive on hand.

The innovation has therefore set itself the task of providing a cover for curtain rails consisting of foam in this way improve that it can also be attached to a curtain rail using conventional attachment methods. i

This problem is solved by the fact that the foam j fabric panel has lateral fastening projections made of a material j, which is harder and mechanically more stable than the material the foaming is of the essence.

According to a preferred embodiment, the projections exist the foam cover made of hard plastic and are partially embedded in the body of the foam cover. To achieve this, the projections made of hard plastic are technically injected at the same time as the production of the foam diaphragm self-trained. Due to this manufacturing process, it is also possible to have the projections in the form of at least one to form along the foam screen extending bar.

Finally, in order to make the foam cover versatile, it is possible to use the comparatively hard plastic Projections are designed to be resilient or rigid in themselves.

In order to be able to attach the foam cover to a curtain

to enable

rail using the well-known locking claw principle /, whereby So in the known version the panel is equipped with areas that can be bent in the transverse direction, the innovation can thereby experience an advantageous development that the projections are each forked at their free ends, so that these free ends can spring away from each other or towards each other your the diaphragm in the area between the two fork-shaped ends can be bent, but the foam cover after bending back into its original Form returns, as the bending then only takes place in an area in which an insert made of hard, resilient Plastic is present.

To ensure that the foam cover is securely fastened, the projections can be formed in the manner of a barb. There are also projections as resilient or rigid Locking claws can be formed and can consist of individual pins or strips arranged at a distance from one another.

Its preferred embodiment is characterized in that the projections or strips are made of rigid PVC and the foam cover is made of foamed rigid PVC with a density of 0.6 g / cnr exists.

: In the following, the innovation is based on exemplary embodiments explained in more detail with reference to the drawings. Show it:

Fig. 1 is a sectional view of a foam cover : lateral projections that are barb-shaped

forms are;

FIG. 2 shows an embodiment similar to that of FIG. 1

with a more simply designed lateral protrusion;

Fig. 3 is a sectional view of a foam screen with lateral Projections according to a further possible embodiment; and

Fig. ¹ I yet another disclosed embodiment at least two spaced lateral Befestigunrcsvorsprüngen.

j Figure 1 shows a sectional view through a schi'um-

j, th plastic existing panel 1, in the upper portion

a lateral fastening projection is embedded at 2 and the section of which protrudes from the material of the panel ne is barbed-shaped. This widerhcu ^r enförmire lateral portion 3 of the attachment projection can entwcdor

in the form of pegs following one another at certain intervals be provided or can consist of a continuous strip, the cross section of which has the shape shown in FIG. Several such loads can also be provided, which are then arranged to run parallel to one another.

A somewhat simpler embodiment is shown in FIG. 2, with also in this embodiment a mounting tab at 2 in the material of the foam cover is embedded and is barbed-shaped at its exposed end in order to thereby to be able to achieve a firm anchoring in the support body of a curtain rail.

Figure 3 shows a slightly modified embodiment, wherein a lateral fastening projection, which is also embedded in the material of the foam cover, at its free end is forked, so that there are effectively two projections 3a and 3b which spring towards or away from one another can, if the foam panel or the fastening projection is pressed into a recess provided for this purpose in a curtain rail.

In the embodiment according to FIG. 3, the lateral Projection 3a, 3b can be provided as a continuous strip.

Yet another very advantageous embodiment is shown in Figure i \. In this embodiment, two lateral projections are embedded at a distance from one another at 2a and 2b in the material of the foam panel 1 and the portion of the fastening projections protruding laterally from the foam panel is equipped with barb-shaped projections ^{at 3a 1 and 3b 'so that} these projections can be pressed into correspondingly arranged recesses of a curtain rail and through the barb-shaped projections at the free ends a; firm anchoring is ensured.

There is now also the possibility of the area 4 between the two fastening projections 3a 'and 3b' also with one

hard

Insert made of solid or resilient material such as / plastic to be filled, with the possibility then being obtained to bend the foam cover 1 in the area ^ to facilitate the latching process, whereby due to the insert in the area ² J the very. Amblende returns to its original shape or shape. This insert in the intermediate area 4 can finally also be formed in one piece with the lateral fastening projections 3a ¹ and 3b ″. As a result, the well-known locking claw principle can also be used with a foam cover without difficulty, although all the advantages of a foam cover are fully retained, for example the light specific weight, the very advantageous pressure uniformity, etc.

It should be emphasized that in all exemplary embodiments the lateral fastening projections both as a pin and / or! can be designed as longitudinal strips and can either be rigid or inherently resilient. They can also Spigots or strips can be designed in very different shapes and forms in order to ensure a secure attachment to the narrow side a curtain rail.

All technical details mentioned in the description and recognizable in the drawings are for the innovation significant.
