BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 to FIG. 10 are views showing an embodiment of the present invention, and show a case where they are used as a bay window curtain rail and a bay window curtain.
[0017]
In the figure, reference numeral 10 denotes a curtain rail, and the curtain rail 10 includes a straight rail 12 and a rotating rail 14. Two rotating rails 14 are prepared, and one end 14a of each rotating rail 14 and both ends 12a, 12a of the straight rail 12 are connected so that the straight rail 12 is sandwiched between the two rotating rails 14. ing.
[0018]
The straight rail 12 further includes an outer rail 12A and an inner rail 12B, and is a telescopic rail in which a part of the inner rail 12B is nested in the outer rail 12A. Each of the outer rail 12A and the inner rail 12B has a substantially U-shaped cross section (FIG. 4), and the runner arm 24 passing through the opening is movable along the lateral opening of the substantially U-shaped cross section. A runner 26 pivotally mounted on the tip of the runner arm 24 can roll on the bottom surface of the straight rail 12. The curtain fabric 22 is suspended from the runner arm 24.
[0019]
Similarly, each of the pivot rails 14 has a substantially U-shaped cross section, and a runner arm 24 passing through the opening is movable along a lateral opening of the substantially U-shaped cross section. Is run on the bottom surface of the rotating rail 14. A side cap 14b is provided at the other end of each rotating rail 14, and a support shaft 18 vertically suspended from a ceiling 21 near both side ends 20a of the bay window 20 rotates around the vertical axis with respect to the ceiling 21. Is rotatably supported.
[0020]
Both ends 12a of the straight rail 12 and one end 14a of the turning rail 14 are connected to each other by a hinge as a joint member 16 so as to be able to turn around a vertical axis, and as shown in FIGS. Either one of both ends 12a of the straight rail 12 or one end 14a of the rotating rail 14, in this example, one end 14a of the rotating rail 14 protrudes toward the other straight rail 12, and has a substantially fan shape in plan view. The connecting portion 14c is formed. The substantially fan-shaped arc-shaped contour of the connecting portion 14c is set so that it can be inserted into the straight rail 12 without interfering with the straight rail 12 along the rotation trajectory of both ends 12a of the straight rail 12. . That is, the connecting portion 14c is located at a position higher than the bottom surface of the substantially U-shaped cross section of the rotating rail 14 and the bottom surface of the substantially U-shaped cross section of the straight rail 12. The bottom of 12a can pass through. The peripheral portion of the connecting portion 14c is continuously connected from the bottom surface of the rotating rail 14 to the connecting portion 14c, and is also continuously connected from the connecting portion 14c to the bottom surfaces of both ends 12a of the straight rail 12, It has an inclined surface.
[0021]
In addition, a support bracket 28 that appropriately supports the straight rail 12 or the rotating rail 14 is fixed to the ceiling 21, and as shown in FIG. The rail 14 can be locked. As shown in FIG. 5, when the push button 28a provided on the support bracket 28 is pressed, the pawl for locking the straight rail 12 or the rotating rail 14 moves, and the straight rail 12 and the rotating rail 14 are moved. Can be removed from the support bracket 28.
[0022]
The straight rail 12 and the two rotating rails 14 are arranged as a curtain rail for a bay window in an arrangement in front of the bay window 20 and in a straight line with a side wall of the bay window 20, and along the bay window 20. And a non-linearly bent arrangement, and the support bracket 28 is fixed at a position corresponding to each arrangement.
[0023]
As shown by the solid line in FIGS. 1 and 6, when the curtain rail 10 is located in front of the bay window 20 and is arranged in a straight line with the wall on the side of the bay window 20, the straight rail 12 and the turn rail The moving rails 14 are linear, the straight rails 12 are contracted, and the connecting portions 14c of the respective rotating rails 14 are almost in a state where the bottom surfaces of both ends 12a of the straight rails 12 overlap. The runner 26 can smoothly move between the straight rail 12 and the rotating rail 14 through the connecting portion 14c and the inclined surface thereof. The state of the curtain rail 10 can be appropriately changed to a state of being spread over the entire curtain rail 10 or a state of being folded at the end of the curtain rail 10 by the movement of the curtain rail 10. However, even when the curtain fabric 22 is in the unfolded state, the curtain fabric 22 is not completely extended, but a plurality of folds are formed and the curtain fabric 22 fabric is in an overlapping state.
[0024]
When it is desired to change the arrangement of FIG. 1 to an arrangement in which the curtain rail 10 is bent non-linearly along the bay window 20, a support bracket supporting the straight rail 12 and the rotating rail 14 in the state of FIG. 28, the rotating rail 14 is rotated around the support shaft 18. When the one end 14a of the rotating rail 14 is moved, both ends 12a of the straight rail 12 are moved together with the bending of the hinge 16, and the length of the straight rail 12 is extended at the same time. In this state, by fixing to the support bracket 28 along the bay window 20, the curtain rail 10 has a shape along the bay window 20, as shown by the phantom line in FIGS. In this case, the overlap between the connecting portion 14c and the lower surfaces of both ends 12a of the straight rail 12 is reduced, but the runner 26 can move between the straight rail 12 and the rotating rail 14 through the connecting portion 14c. This is the same as the state of FIG. Then, the curtain fabric 22 suspended from the runner arm 24 can be appropriately changed to a state of being spread over the entire curtain rail 10 by moving the runner 26 or a state of being folded at the end of the curtain rail 10. . In this case, since the total length of the curtain rail 10 is long, the folds of the curtain fabric 22 are smaller than those in FIG. 1 when the curtain fabric 22 is deployed.
[0025]
Optionally, the curtain fabric 22 is made of a translucent fabric, and is in a non-light-shielded state when it is relatively extended as shown in FIG. 7, and when the curtain fabric 22 is loose as shown in FIG. It is possible to use a cloth having a high degree of light shielding because of overlapping, for example, at night, light shielding and heat insulation are performed as shown in FIG. 1, and during daytime, light transmission is increased as shown in FIG. A method of using the space of the bay window can be used in an open manner, and the switching can be easily performed.
[0026]
Optionally, a guide for guiding the movement of the joint member 16 can be provided on the ceiling 21 in accordance with the movement of the one end 14a of the rotating rail 14.
[0027]
In this embodiment, the straight rail 12 is a telescopic rail. However, the rotating rail may be a telescopic rail instead of the straight rail, or both the straight rail and the retraction rail may be telescopic rails. It may be.
[0028]
Further, in this embodiment, one curtain rail 12 for the bay window is composed of one straight rail 12 and two rotating rails 14. However, the number of straight rails 12 is not limited to this, and the number of rotating rails can be varied. By combining with the rail 14, a curtain rail can be configured.
[0029]
【The invention's effect】
As described above, according to the present invention, by combining the straight rail and the rotating rail, one end of the straight rail and one end of the rotating rail are rotatably connected by the joint member, and the other ends of the rotating rail are connected. The end is rotatably supported on a fixed body such as a window frame, a wall, a ceiling, and the like, and one end of a straight rail is movable with one end of a swing rail, and a plurality of arrangements are made with the straight rail and the swing rail. Because it was made possible, a variety of curtains can be obtained.
[0030]
Further, when the straight rail and / or the rotating rail are telescopic rails that can be extended and contracted, the length of the entire length of the curtain rail can also be changed, so that a more varied curtain can be obtained. Then, as an example of the change of the curtain, the arrangement in which the curtain rail becomes linear by the expansion and contraction of the telescopic rail and the arrangement in which the curtain rail becomes non-linear can be easily achieved.
[0031]
Further, a curtain rail suitable for a bay window can be provided by a combination of a straight rail and two rotating rails.
[0032]
Further, a connecting portion projecting toward one of the straight rail and the rotating rail is formed at a connecting portion between the straight rail and the rotating rail, and the other of the connecting portion is formed at the other of the connecting portion. By providing the arc-shaped contour along the rotation trajectory, regardless of the rotation angle of the rotation rail and the straight rail, without obstructing the rotation between the rotation rail and the straight rail, A gap can not be formed between the two.
[0033]
Further, when the curtain fabric is suspended from the curtain rail, and the straight rail and the rotating rail are arranged in a straight line on the curtain fabric, the curtain fabric is loosened and overlaps to transmit. When the light is in a light-shielding state with a small amount of light, and when the straight rail and the rotating rail are rotated to each other via the joint member so as to be non-linear, the curtain fabric is stretched and becomes a non-light-shielding state with a large amount of transmitted light. Thus, switching between light shielding and non-light shielding by the curtain can be performed in accordance with a change in the shape of the curtain rail.
