Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a curtain rail that opens and closes curtains provided on the left and right sides by operating strings.

BACKGROUND TECHNOLOGY In general, when curtains are overlapped in the center to block light when the curtains are closed, there is a method in which crossed runners are placed on one curtain rail on the left and right.
A method was seen in which curtains were attached separately to two curtain rails.

Problems to be Solved by the Invention However, in the method of using crossing runners on a single curtain rail, there is a limit to the intersecting dimension of the curtain by the crossing runners, that is, the overlapping dimension, and a complete light blocking effect could not be obtained. On the other hand, in the method using two curtain rails,
The dimensions of the curtains that overlap in the center can be set arbitrarily, and a reliable light blocking effect can be obtained. On the other hand, a drawstring is strung between the two curtain rails, and a tension pulley is used to prevent the string from loosening. In other words, the structure was complicated.

Means for Solving the Problems Therefore, the present invention aims to provide a curtain rail that does not require a tension pulley and has a simple structure, while having the features of a system using two curtain rails. Two rails ₁ having a length l ₂ longer than half of the finished length l 1, with an interval of 4 in the front and back, overlapping and paralleling an appropriate length l ₃ to have a finished length l ₁ , 2, a support plate 5 provided at the end of the overlapped side of each rail 1, 2,
Two large and small horizontal guide rollers 6 and 7 attached to each support plate 5, a horizontal turn roller 8 provided at the other end of one rail 1, and two vertical guide rollers provided at the other end of the other rail 2. A guide roller 9 and a leading runner 10 attached to each rail 1, 2
, the vertical guide roller 9, the horizontal guide rollers 6, 7, and the horizontal turn roller 8 pass through the rails 1, 2, and both leading runners 10
It consists of a drawstring 11 that moves the objects in opposite directions.

Function: Therefore, the drawstring 11 hangs endlessly from the vertical guide rollers 9, and one of the vertical guide rollers 9
The drawstring 11 enters the rail 2 through the runner 10, connects the leading runner 10, enters the horizontal guide roller 7 of the other rail 1 via the horizontal guide roller 6, the interval 4, and connects the horizontal turn roller at the end. 8, connects the leading runner 10, reenters the rail 2 from the horizontal guide roller 7 via the horizontal guide roller 6 and the spacing 4, and reaches the vertical guide roller 9.

At this time, when reaching from one rail to the other rail, the drawstring 11 is passed over the horizontal guide rollers 6 and 7 from large to small or from small to large. By pulling one of them and moving the entire drawstring 11, the leading runner 10 connected thereto is moved and the curtain is opened and closed.

Embodiment Hereinafter, an embodiment of the present invention will be explained with reference to the drawings. Reference numerals 1 and 2 are rails with a drawstring advancing/retreating path 3 at the front and back of the interior and having a length l ₂ longer than half of the finished length l ₁ , and both rails. 1 and 2 are placed at a distance of 4 in front and behind, with a finished length of _l1 , and a suitable length of _l3 are overlapped and fixed in parallel. Reference numeral 5 denotes a support plate protruding from the end of the overlapping side of each rail 1, 2, which biases the axis in the direction of the parallel rails 1, 2, and separates a part of the circumference from each other into a separate advancing/retreating path 3. Two horizontal guide rollers 6 and 7, large and small, corresponding to the 8 is one rail 1
A horizontal turn roller is provided at the other end, and its circumference corresponds to the advance/retreat path 3 of the rail 1. Reference numeral 9 denotes vertical guide rollers provided at the other end of the other rail 2, two of which are arranged in parallel corresponding to the advance/retreat path 3 of the rail 2. 10 is a leading runner attached to the rails 1 and 2; 11 is a drawstring fitted into the advance/retreat path 3, which hangs endlessly from the vertical guide roller 9;
0, and from one rail 2 to the other rail 1
It moves across between horizontal guide rollers 6 and 7 and is turned back by horizontal turn roller 8. 12 is a bracket for fixing the rails 1 and 2; 13 is a support; and 14 is a cover.

Effects of the invention As mentioned above, the invention consists of two rails _{1 and 2} with a length l 2 longer than half of the finished length l ₁ arranged one behind the other, and overlapped with an appropriate length l _3. Therefore,
The curtains attached to the two rails 1 and 2 will be fully overlapped in the center,
The light shielding effect is extremely large. In addition, horizontal guide rollers 6 and 7 are provided at the overlapping ends of both rails 1 and 2, respectively, and since the rails 1 and 2 are arranged in parallel with an interval of 4, one rail 1
The drawstring 11 from one rail to the other rail 2 can be stretched through the horizontal guide rollers 6, 7 and the interval 4, and is used in the same way as a conventional drawstring curtain rail, making it an innovative curtain that does not require a tension pulley. It's a rail.
