Description

[Detailed Description of the Invention] (a) Field of the Invention This invention relates to a connecting member for a curtain rail such as that used in curtains stretched over polygonal bay windows such as triangular, pentagonal, and octagonal bay windows.

(b) Background of the invention When installing curtains on the polygonal bay window in the above example,
A curtain rail is laid at a predetermined position on the ceiling side along each window, but if the lift cord of each curtain is configured to be operated from one position,
It is necessary to pass the lifting cords of each curtain through the curtain rail and gather them at the operating position. To do this, the ends of each curtain must be brought close to each other so that they are connected, and the connecting ends of each curtain rail must be connected to each other. Since the installation direction of the curtain rail is bent in accordance with the bay window surface, a guide roller for guiding the lifting cord is required at the connecting end of the curtain rail.

Conventionally, there has been a corner end member that is attached to the connecting end of the curtain rail to guide the lifting cord (Japanese Utility Model Publication No. 59-59181).

A guide roller that guides the lifting cord is pivotally supported on the above-mentioned corner end member, and the lifting cord comes into contact with this guide roller and is changed in the direction in which the curtain rail is laid, but this corner end member constitutes a corner. Since it is attached to the opposing ends of two curtain rails, the ends of each curtain rail at the corners are free, which makes it easy to lay each curtain rail in different positions, making the workability of installing curtain rails poor. Also, there was a problem in that the guide of the lifting cord deteriorated.

(C) Purpose of the invention In this invention, a pair of connecting members fixed to the connecting end of the curtain rail are pivotally connected by a shaft, and a guide roller is provided using this shaft, so that the curtain rail can be laid easily. It is an object of the present invention to provide a curtain rail connecting member that is easy to guide and also stabilizes the guide position of a lifting cord at a corner portion.

(e) Summary of the invention In this invention, a U-shaped connecting piece extending toward the bending side is provided at each opposing end of a pair of connecting members having a hollow in the center, and the overlapping part of these connecting pieces is The curtain rail connecting member is characterized in that the curtain rail connecting member is pivotally connected at a bent inner position with a shaft and is provided with a rollable guide roller in the middle part of the shaft.

(e) Effects of the invention According to this invention, since the mutual ends of the curtain rails are connected at the corner portion by the curtain rail connecting member, the connection interval, connection position, and bending direction of the curtain rails are determined, and the curtain rail installation is made easier. Improves work efficiency.

Furthermore, since the guide roller for guiding the lifting cord is provided using a shaft to which a connecting member is pivotally connected, a separate shaft for supporting the guide roller is not required, and the structure is simplified.

(F) Embodiment of the invention An embodiment of the invention will be described below in detail based on the drawings.

The drawing shows a curtain rail connecting member, and in FIG. 5, a curtain rail 1 for hanging a curtain is shown.
0... are laid at a predetermined position on the ceiling side along the window surface of the polygonal bay window, and curtain rail connecting members 11... that connect mutual ends of the curtain rails 10... are attached to the corners of each curtain rail 10... has been done.

When the above-mentioned curtain lifting/lowering operation position is set to the rightmost position 10a in the figure, each curtain rail 10
The lift cord 12 of the curtain suspended on... is
It is inserted through the inside of each curtain rail 10 and guided to the operating position 10a.

Note that guide rollers 13 for supporting the lifting cords 12 are laterally installed inside each curtain rail 10 at necessary locations.

As shown in FIGS. 1 to 4, the curtain rail connecting member 11 described above has a cavity formed in the center,
a pair of U-shaped connection members 14 opening upward;
14, the opposite ends of the connecting members 14, 14 have curved outer side sides 15, 15 extending in opposite directions, and a connector extending to the bent inner side on the extending side sides 15, 15. Connection pieces 16, 16 in the shape of a square are provided in succession.

The U-shape of each of the connection pieces 16, 16 described above is formed such that one side is large and the other is small, and the small connection pieces are inserted inside the large connection piece and overlapped with each other, resulting in the overlapping connection pieces 16, 16 A guide roller 18 for guiding the lifting cord 12 in the bending direction is loosely fitted in the middle part of the shaft 17.

Bottom side 1 on the free end side of each of the above-mentioned connecting members 14, 14
Female screws 20, 20 are formed in the female screws 9, 19, and screws 22, 22 are screwed into these female screws 20, 20 via contact plates 21, 21.

Further, at one end of the above-mentioned contact plates 21, 21, a rotation stop 23, 23 is provided in a row facing upward, and on the bottom side 19, 19 corresponding to the rotation stop 23, 23, a locking recess 24, 24 is provided. are formed, and when these engage with each other, the contact plates 21, 21 are screwed in place.

Curtain rails 10, 1 of connecting members 14, 14
0 is fixed by sandwiching the opening edge of the curtain rail 10 between the bottom side 19 and the cover plate 21 and tightening the screws 22.

In addition, 25 in the figure is an ear member, and the connection member 1
4 and 14 are inserted into the ends of the curtain rails 10...

The curtain rail connecting member 11 configured as described above has its free end inserted into the end of the curtain rail 10 and is fixed via the contact plate 21 and screws 22.

The above-mentioned curtain rail connecting member 11... is the shaft 17
Since the curtain rails 10 can be bent at the positions, each curtain rail 10 can be laid along the window surface of the polygonal bay window.

At this time, the connection interval of the curtain rails 10...
The connection position and bending direction are determined, improving the workability of installing curtain rails.

Further, the lifting cord 12 passing through the curtain rail 10 is inserted between the guide roller 18 and the connecting piece 16 at the corner portion, and is further guided by the guide roller 18 to change its direction.

FIG. 6 shows another example, in which parts having the same functions as those in the above-mentioned first embodiment are given the same reference numerals. As in the case of the first embodiment, U-shaped connection pieces 16, 16 are formed, but between these connection pieces 16, 16 there is a pair of upper and lower intermediary connection pieces 2.
6 and 26 are interposed, and the respective overlapping parts are connected to the axis 1.
7 and 17 are continuous, and guide rollers 18 and 18 are loosely fitted to each shaft 17 and 17, respectively.

In this way, the two positions may be pivotally connected and the guide roller 18 may be provided using the shaft 17 of each connecting portion. Furthermore, the number of guide rollers 18 described above can also be increased.

In addition, in the above-mentioned embodiment, both connection pieces 16, 16
Although they extend from the same direction, they may be formed to extend from opposite bending directions.

Further, although the shaft 17 and the guide roller 18 are formed separately, they may be formed integrally.
