Description

[Detailed Description of the Invention] The present invention relates to a twin roll blind.

Generally, the width of roll blinds is up to about 2 meters, but this is because it is difficult to stretch wide cloth evenly, and the rolls become more likely to twist as the width increases. Therefore, when installing roll blinds in a wide space, for example a 4m wide window, you will need to install two 2m wide blinds. When two conventional roll blinds are installed in a row, the width of the adjacent brackets and the unwrapped edge of the blind, i.e. the width of the unshielded strip of the blind, is quite wide (30 mm).
(above), there was a problem that not only the light shielding was insufficient, but also the appearance was bad.

The object of the present invention is to minimize the gap between adjacent blinds in a double roll blind that is not covered with cloth. In order to achieve the above-mentioned problems, the twin roll blind of the present invention has bearing parts installed inside the adjacent ends of two cloth-wrapped rolls,
It has a connecting shaft fitted into the bearing portion and an intermediate bracket that supports the connecting shaft. Preferably, the intermediate bracket fixedly supports the connecting shaft, and both bearings are rotatably supported by the connecting shaft.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The continuous roller blind of the present invention will be explained based on an embodiment shown in the drawings. As shown in Figure 1,
Bearings 3 and 3' are respectively mounted on bearing blocks 2 and 2' provided at the adjacent inner ends of the two consecutively mounted roll blinds 1 and 1', and both shaft portions of the coupling shaft 4 are fitted into the bearings. The bearing blocks 2, 2' are connected to the rolls 5, 5' of the blinds 1, 1'.
Insert at the inner end of the Two blinds 1, 1'
The outer end portion 6 of the connecting shaft 4 is removably fitted into the left and right brackets 7 (only one side is shown), and the central portion of the connecting shaft 4 is removably attached to a plate-shaped intermediate bracket 8. Both brackets 7 and 8 are fixed to a window frame or the like.
The rolls 5 and 5' on which the cloths 9 and 9' are wound approach each other,
The distance between the two (5 mm or less) is extremely narrow compared to the conventional one.

As shown in FIG. 2, the cross section of the central portion 11 of the coupling shaft 4 is formed into an angular shape and is fitted into the angular groove 10 of the intermediate bracket 8, thereby fixing the coupling shaft 4. Whether the intermediate bracket 8 is mounted on the ceiling or on the front, the groove 1 is provided to prevent the connecting shaft 4 from easily falling out of the groove 10.
It is desirable that 0 be oblique to the vertical direction.

Since the continuous roller blinds of the present invention have very narrow gaps between the continuous roller blinds, it is possible to block light from a wide window in a stylish manner. Furthermore, since the twin roll blinds can be opened and closed individually, it is possible to control the light with finer grain than when using a single roll blind.

In the illustrated embodiment, the bearing block 2 is rotatably fitted to the coupling shaft 4 via the ball bearing 3, but instead of the ball bearing, a roll bearing, a needle bearing, a simple plain bearing, an oil-impregnated plain bearing, a lubricated plastic can be used. Bearings etc. may also be used.
