Description

Description: Inlet or filling

The present invention relates to an inlet or a chute, with a lower plate and an upper plate and with inner webs which divide the interior of the inlet or the chute into several cassettes, each of which can be filled with down and/or feathers.

Inlets or fillings of the type mentioned are generally known due to their widespread use. The bottom plate and the top plate are directly connected to one another by means of the inner bars. The cassettes formed by the inner bars can be filled with down and/or feathers to form a finished duvet. Due to their large volume, the down and/or feathers bulge the bottom plate and the top plate downwards and upwards in the area between the inner bars, so that the finished duvet is at its thinnest in the area of the inner bars and therefore has the least thermal insulation effect there.

The object of the present invention is to provide an inlet or a filler with which an upper bed can be produced which has an improved thermal insulation effect overall and in particular in the area of the inner webs.

The object is achieved according to the invention with an inlay or a chute of the type mentioned at the outset, which is characterized in that two additional middle plates are arranged between the lower plate and the upper plate and in that the inner webs are arranged on the one hand between the lower plate and the first middle plate immediately adjacent to it and on the other hand between the upper plate and the second middle plate immediately adjacent to it.

The inlay or the filler according to the invention offers a particularly good thermal insulation effect because its insulation function is practically equivalent to two conventional inlays or fillers placed on top of each other. The improved thermal insulation effect is also contributed to by the fact that an air gap is formed between the two middle panels, which, together with the down and/or feathers in the cassettes above and below the two middle panels, effectively prevents heat from passing through. In particular, the invention prevents continuous cold bridges from forming in the area of the inner webs because there are no longer any inner webs running from the bottom panel to the top panel. The amount of down and/or feathers used to fill this insert or this filling does not have to be twice as large as for a conventional duvet, since due to the design advantages of the insert or the filling according to the invention, a better insulation effect is achieved than with a conventional duvet by using the same amount of down and/or feathers and distributing them over the two layers of cassettes. If even greater thermal insulation is desired, this can be achieved simply by increasing the amount of down and/or feathers.

In order to obtain uniform cassette sizes within the inlay or the chute and in the two layers of the cassettes, the inner webs between the bottom plate and the first middle plate and the inner webs between the top plate and the second middle plate are preferably arranged so that they coincide with one another when viewed from above on the inlay or the chute. Alternatively, it is of course also possible to offset the inner webs of the two layers against one another, which requires more effort during production but can be expected to provide an even better insulation effect.

To prevent the two middle plates from moving too far away from each other in an undesirable manner, additional inner struts can be installed between the two middle plates.

With regard to the materials used for the ticking or the filling according to the invention, it is preferably provided that the lower plate and the upper plate consist of ticking fabric in filling qualities, that the middle plates consist of fleece or light fabric and that the inner webs consist of gauze or ticking tape.

In order to connect the bottom plate and the top plate as well as the two middle plates in a way that is down and feather-proof and mechanically durable on the one hand and to achieve an attractive appearance of the finished top bed on the other, the ticking or the filling is preferably edged all around by a piping tape that connects the bottom and top plates as well as the middle plates to each other at the edges.

In order to enable the later filling of the inlet or the filling with down and/or feathers with as little effort as possible and through as few filling openings as possible, it is further provided that the inlet or the filling

chute has an even number of cassettes in its transverse and/or longitudinal direction and that on a transverse or longitudinal edge of the insert or the chute, one filling opening is left free in the insert or chute edge for every two pairs of cassettes lying one above the other, with each filling opening extending over a part of the edge length of four adjacent cassettes. If, for example, the insert or the chute is divided into 4 x 6 cassettes, two filling openings on the narrow side of the insert or the chute are sufficient to fill all the cassettes. This requires that the inner webs running parallel to the narrow side of the ticking or the filling opening each have an opening in each cassette through which a filling pipe can be gradually introduced from one narrow side of the ticking or the filling opening into all of the cassettes located behind the filling opening in order to blow the required amount of down and/or feathers into each cassette.

In an alternative, simplified design, only a single center plate is provided instead of two center plates, which accordingly saves the material for a center plate.

For this design, it is advisable not to arrange the inner webs so that they are congruent with one another, but to install them with a lateral offset. This also avoids continuous cold bridges between the underside and the top of the insert or the filler.

An embodiment of an inlay according to the invention is explained below using a drawing. The figures of the drawing show:

Figure 1 shows an inlet in a schematic representation, partly in plan view and partly in horizontal section, and

Figure 2 shows the inlet from Figure 1 in a schematic cross-section along the line II-II in Figure 1.

As shown in Figure 1 of the drawing, the inlay 1 has a rectangular outline, as is usual. The inlay 1 has a bottom plate 2 facing away from the viewer and an upper plate 3 on the top, of which only the outer edge area is visible here; the inlay 1 is shown cut open in its central part.

Between the lower plate 2 and the upper plate 3, two additional middle plates 4, 4' are arranged, of which the upper middle plate 4' is visible, while the other middle plate 4 is invisibly located underneath.

The insert also comprises several inner webs 5, 5', which divide the insert 1 into several cassettes 10. A first group of inner webs 5 is provided between the bottom plate 2 and the lower middle plate 4 and a second group of inner webs 5' is provided between the upper middle plate 4' and the top plate 3. There is an air space or gap between the two middle plates 4, 4'.

The inlay 1 is edged all around its circumference with a piping tape 6, which connects the edges of the lower panel 2, the upper panel 3 and the middle panels 4, 4' and seals them tightly towards the outside.

The individual cassettes 10 can be filled with down and/or feathers to form an upper bed. For this purpose, in the illustrated embodiment of the insert 1

on the lower narrow side of which in Figure 1 two filling openings 11, 11' are provided. So that the cassettes located further away from the lower narrow side of the insert 1 can also be filled, the inner webs 5, 5' running parallel to the narrow side of the insert 1 are each interrupted near the inner webs 5, 5' running in the longitudinal direction of the insert 1. Through these interruptions a filling pipe or hose for blowing in the down and/or feathers can be guided from the filling opening 11, 11' into the rear cassette 10, i.e. the upper cassette 10 in Figure 1, in order to gradually fill the cassettes 10 with the specified amount of down and/or feathers from there. After the filling process the filling openings 11, 11' are closed, usually sewn up.

Figure 2 of the drawing shows the insert 1 from Figure 1 in cross section along the line II - II, also in a schematic representation. Figure 2 also shows the position of the section line I - I, according to which the insert 1 is shown in Figure 1.

According to Figure 2, the bottom plate 2 forms the underside and the top plate 3 the top of the inlay 1. The two middle plates 4, 4' are arranged parallel to each other between the bottom plate 2 and the top plate 3. On the edge side, i.e. on the left and right in Figure 2, the piping tape 6 can be seen, by means of which the bottom plate 2, the top plate 3 and the middle plates 4, 4' are tightly connected to each other all the way around.

Furthermore, the position and arrangement of the inner webs 5, 5' can be seen particularly clearly in Figure 2. A first, lower group of inner webs 5 is attached between the lower plate 2 and the lower middle plate 4; a second, upper group of inner webs 5' is attached between the upper middle plate 4' and the upper plate 3.

Between the two middle plates 4, 4' lies the air space 12.

The cassettes 10, which are formed in two layers in the insert 1, can be filled with down and/or feathers, as already explained above. The air space 12 is preferably not filled with down and/or feathers. If required, however, a light, flexible and voluminous intermediate layer can be inserted here, for example a foam layer, which ensures a constant height and thus a good insulating effect of the air space 12 between the two middle plates 4, 4'.

Figure 2 also clearly illustrates the high thermal insulation effect achieved with the insert 1. The function of the insert 1 according to the drawing corresponds in principle to the insulation function of two inserts arranged one above the other, with an additional insulation effect being achieved by the air space 12. The insulation effect of the insert 1 thus goes beyond the combined effect of two conventional inserts. Cold bridges in the area of the inner webs 5, 5' from the bottom to the top of the insert 1 can no longer occur here because there are no longer any inner webs running from the bottom plate 2 to the top plate 3.

In an alternative, simplified design, it is possible to provide only a single middle plate instead of the two middle plates 4, 4'. For this design, it is then expedient not to arrange the inner webs 5, 5' so that they are congruent with one another, as in the embodiment shown, but to attach them with a lateral offset. This also avoids continuous cold bridges between the underside and the top of the insert 1.
