JPH09242286A - Awning, especially cartridge awning - Google Patents

Abstract

PROBLEM TO BE SOLVED: To avoid concentrated frictional motion in a cloth central region while holding a basic advantage of a cloth guide board on an awning. SOLUTION: A cartridge awning includes awning cloth 8 free to wind around a cloth shaft 6 supported in an awning, especially in a cartridge free to rotate. Additionally, the cloth shaft 6 is supported by a cloth shaft bearing (square bearing 10) respectively on its both sides, furnished with a cloth guide board 1, and winding cloth 5 formed by the awning cloth 8 is supported against deflection in the cross direction against the delivery direction through the cloth guide 1. Thereby, it is constituted so that each of the cloth shaft bearings (square bearing 10) is guided while shifting its direction roughly in the delivery direction (arrow 9).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sunshade, in particular a fabric shaft (Tuchwelle) rotatably supported in a cartridge.
It is intended for cartridge awnings containing awning fabric that can be wrapped around, and the fabric shaft is supported by the fabric shaft bearings at both ends, and the fabric guide plate (Tuchleitbleche)
Is provided, and the wound cloth formed by the sunshade cloth is supported by the cloth guide plate against bending in the lateral direction with respect to the feeding direction.

2. Description of the Prior Art Cartridge shades are becoming increasingly popular in the market. It is designed to have the smallest possible structural size. In larger equipment, the dough shaft and the discharge roller (Ausfallrohr) tend to bend in the lateral direction with respect to the feeding direction, which is aesthetically effective or the moisture discharge (Wassera
Even if bfuehrung) is taken into consideration, it will cause unacceptable material deflection. Therefore, such cartridge shades are increasingly equipped with a fabric guide plate that counteracts this action. Known fabric guide plates are installed to support the fabric dispensed within the cartridge and thereby prevent sagging. Similar problems become apparent with other awnings with fabric guides.

[0003]

Certainly, this dough guide plate has the drawback of producing a concentrated frictional movement in the center of the dough when the dough shaft is most flexed there during unwinding.

It is therefore an object of the present invention to avoid such intensive frictional movements in the central area of the fabric while retaining the basic advantages of the fabric guide plate.

[0005]

According to the present invention, this problem is solved by the fact that the respective fabric shaft bearings are guided in such a manner that they can be displaced substantially in the payout direction or are displaced in position. In this way, the dough shaft moves toward the dough guide plate as the winding diameter decreases, and the dough always makes the same contact with the dough guide plate regardless of the winding diameter. Guarantees to avoid particularly strong frictional movements at.

Each fabric shaft bearing is a quadrangle bearing (Lagervi
It is preferable that two vertical side surfaces including the erkant, which are parallel to each other at the four corners, are used as a cam surface to be guided between two guide ribs extending in parallel to each other.

Furthermore, these guide ribs are expediently arranged on the fabric shaft holder, in particular on the inside of the side wall of the cartridge, which results in a structure which is particularly particularly easy to manufacture and easy to assemble. .

Finally, within the scope of the invention, a final stop is provided for the displacement movement (displacement) of each quadrilateral bearing, so that the displacement path is well defined.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below in detail based on preferred embodiments with reference to the drawings.

The structure of the cartridge shade is generally known, for example, from European Patent Application Publication No. 186742 (EP
0 186 742 A1). For the purpose of illustrating the invention, only the dough guide plate 1 including the lower part 2 and the upper part 3 which are connected to each other via the forming part 4 is shown in the drawing. The dough guide plate 1 is formed so as to surround the wound dough 5 and the dough shaft 6 substantially concentrically, and to provide an outlet opening 7 for paying out the shade fabric 8 in the payout direction (arrow 9).

The fabric shaft 6 is not directly supported on the side wall of the cartridge, but is supported on the quadrilateral bearing 10 in which the parallel side surfaces 11 and 12 are arranged between the two parallel guide ribs 13. . These guide ribs 13 are further connected to the inside of the side wall of the cartridge on their own side. Correspondingly, the four-sided ridge bearing 10 and the material shaft 6 can be displaced (positional displacement) in the feeding direction (arrow 9).

In the state shown in FIG. 1, the roll dough has approximately the maximum diameter, in other words the shade fabric 8 has not been paid out at all or has not been paid out at all. In this state, the material shaft 6 and the quadrangle bearing 10
Is at the left-hand limit in the drawing of the displacement movement defined by the guide ribs 13.

As the winding diameter decreases, as can be appreciated from the comparison between FIG. 1 and FIG.
And to the right in the drawing, still ensuring that the dough 8 or the dough 5 abuts the lower part 2 of the dough guide plate 1 over the entire width of the shade device and correspondingly an equal burden pressure distribution (Auflagedruckverteilung). Is guaranteed.

FIG. 3 shows the situation in which the awning is finally fully extended and the wrapping material 5 correspondingly has its minimum diameter. The quadrilateral bearing 10 and the fabric shaft 6 are in the rightmost position in the drawing of the displacement path and still ensure that the winding fabric is supported on the guide surface 1 by the piece 2 over its entire width.

When the shade fabric 8 is stored, the displacement movement of the fabric shaft 6 is performed smoothly.

[Brief description of drawings]

FIG. 1 is a schematic cross-sectional view through a dough shaft having a dough guide plate at a certain feeding stage.

FIG. 2 is a schematic cross-sectional view at a payout stage different from that of FIG. 1, and thus at different dough winding diameters.

FIG. 3 is a schematic cross-sectional view at a payout stage different from FIGS. 1 and 2, and thus at different dough winding diameters.
