[Problems to be solved by the device]

 However, in the conventional handy type curtain rail bending tool 70 as shown in FIG. 8, since the bending points at the bending points P and Q of the bay window 60 could not be accurately determined, the curtain rail 20 was bent. At this time, the distance between the curved points P and Q was longer or shorter than the length A of the straight portion of the bay window 60, and a certain size could not be obtained. For this reason, a certain curtain rail 20 has a large space between the bay window 60 and the curtain rail 20, and a certain curtain rail 20 has a gap between the bay window 60 and the curtain rail 20 which is too narrow, so that the curtain 50 is opened. There was a problem that the curtain could not be moved smoothly because it was caught in the room.

Furthermore, in the conventional handy type curtain rail bending tool 70, after bending the inclined portion 27 at one end of the curtain rail 20, the curtain rail 20 is easily removed from the handy type curtain rail bending tool 70. However, there is a drawback that it is difficult to take out the curtain rail 20 from the handy type curtain rail bending tool 70 after bending the inclined portion 28 at the other end.

The present invention eliminates the above-mentioned adverse effects and provides a curtain rail bending tool which can always maintain the distance C between the bay window 60 and the curtain rail 20 and can bend the curtain rail 20 at a constant position. is there.

When the curtain rails 20 and 25 shown in FIG. 2 are bent, the curtain rail 20 is kept at a predetermined dimension between the bay window 60, for example, C, and the inner curtain rail 25 is kept at a predetermined distance from the curtain rail 20. It is necessary to keep Hereinafter, a process of bending the curved portion P'point and the curved portion Q'point of the curtain rail 20 by the curtain rail bending tool according to the present invention will be described.

(1) First, as described with reference to FIG. 2B, the curtain rail 20 is cut into a length of A + 2 (BD) as a whole, and each end of the curtain rail 20 is cut to BD. Mark the points P'and Q'at the end of the length.

(2) As shown in FIG. 4, the point P ′ of the curtain rail 20 is aligned with the point P of one end of the fixed block 2, the inclined portion 27 shown by the dotted line is pushed in the direction of the arrow, and the predetermined point shown by the solid line is obtained. Bend to the position.

(3) Next, as shown in FIG. 5, the Q ′ point of the curtain rail 20 is aligned with the other Q point of the fixed block 2 of the curtain rail bending tool, and the inclined portion 28 indicated by the dotted line is formed. Push in the direction of the arrow and bend to the designated position indicated by the solid line.

By the above-mentioned three processes, the inclined portion of the curtain rail 20 can be curved along the bay window 60 to obtain the curtain rail 20 having a distance C from the bay window 60. Thus, by cutting the curtain rail 20 into a predetermined length by taking the dimension D into consideration from the beginning, it is possible to easily form a curtain rail in which the curtain can smoothly move along the bay window 60. In addition, in the above, the curtain rail 20 was cut to the length of A + 2 (BD), and the points P'and Q'were marked, but the curtain rail of (1) above was marked. The cutting step (1) at the end of 20 is omitted, the P ′ point and the Q ′ point are marked without cutting the curtain rail 20, and then the curtain rail 20 is cut by the steps (2) and (3). After bending both ends, the end of the curtain rail 20 may be cut along with the bay window 60.

Further, in the above description, the width W1 of the fixed block 2 + the first interval d1 is set to the same width as the interval C. The distance d1 between the fixed block 2 and the first movable block 3 is selected to have a width that allows the curtain rail 20 to be easily inserted and removed. For example, when the width of the curtain rail is 5 mm, it is selected to be about 6 mm, for example. The first distance d1 can be changed by adjusting the thumbscrews 5 and 6 according to the type of the curtain rail 20.

In FIGS. 1 and 5, the second movable block 4 is used to form the inner curtain rail 25 when a double curtain rail is required. Even when the inner curtain rail 25 is bent, it can be performed in the same manner as the above-mentioned bending steps (1) to (3) of the curtain rail 20. In order to bend the inner curtain rail 25, first, the entire inner curtain rail 25 is cut into a length of A-2F + 2 (B-D-G) as described in FIG. Mark points P "and Q" from the ends of the curtain rail 25 to the length B-D-G.

Next, the P ″ point of the inner curtain rail 25 is aligned with one end of the second movable block 4 shown in FIG. 5, and the inclined portion of the inner curtain rail 25 is set as the inclined portion 27 of the curtain rail 20. Similarly, push and bend to the position shown by the solid line.Next, align the Q ″ point of the inner curtain rail 25 with the other end of the second movable block 4 shown in FIG. Is bent to the position shown by the solid line in the same manner as the inclined portion 28 of the curtain rail 20.

The distance between the first curtain rail 20 and the inner curtain rail 25 is determined by the width W2 of the first movable block. This width is usually about 5 cm, but the distance between the curtain rail 20 and the inside curtain rail 25 can be changed by replacing the first movable block 3 having a different width W2 depending on the type of the curtain. . Further, the distance d 2 between the first movable block 3 and the second movable block 4 is selected to be a width such that the inner curtain rail 25 can be easily inserted and taken out similarly to the above. This distance d2 can be adjusted by the thumbscrews 7 and 8 according to the type of the inner curtain rail 25. The end of the inner curtain rail 25 is bent so as to coincide with the end of the curtain rail 20. In this way, the end of the curtain rail 20 and the end of the inner curtain rail 25 are aligned with each other, so that the curtain rail 20 and the inner curtain rail are overlapped at the end.

In the above, the example in which the curtain rail 25 is inserted and curved between the first movable block 3 and the second movable block 4 has been shown, but the curtain rail 25 is fixed similarly to the curtain rail 20. It can also be inserted between the block 2 and the first movable block 3 to bend. In this case, since the inclination angles of the inclined portions of the curtain rail 20 and the inside curtain rail 25 are different, it is necessary to adjust the inclination angle of the inside curtain rail 25 after the bending in accordance with the curtain rail 20.

In the above, the example in which the first movable block 3 and the second movable block 4 are adjusted by the thumbscrew has been shown, but only the first movable block 3 is made movable and the second movable block 3 is made movable. When the block 4 is replaced with the second fixed block and the curtain rail 20 is formed, the first movable block 3 is moved so that the fixed block 2 and the first movable block 3 have the first distance d1. When the inner curtain rail 25 is moved, the first movable block 3 is moved so that the first movable block 3 and the second fixed block have the second distance d2. Thus, it is possible to provide a curtain rail bending tool capable of forming both the curtain rail 20 and the inner curtain rail 25.
