And it is fastened with a nut through the slit 1s of the guide rail body 1.

Each of the spacers 3c, 3f, 3j is formed in a cylindrical shape, and its axial length is determined so that the pulley 3 can be positioned at a substantially central portion in the guide rail body 1. The slit 1 s is for adjusting the distance between the pulleys 3, 3 and for adjusting the tension on the loop-shaped string 5 wrapped around the pulleys 3, 3. Reference numeral 4 denotes a stopper for fixing an end of the curtain K. The stopper 4 is provided on both sides of the guide groove 1g of the guide rail body 1 in the guide groove 1.
A pair of holding pieces 4a, 4b to be held from outside and inside of g
A hanging piece 4e having an engaging hole 4d for engaging a hanging tool 37c fixed to the upper end of the curtain extends below the guide rail body 1 on the outer holding piece 4a. On the other side, a contact piece 4f for stopping the floating runner 9 is extended from the guide groove 1g into the guide rail body 1.

The loop-shaped string 5 is made of a material having extremely low elasticity, such as Kevlar fiber or wire, and is looped over the pulleys 3, 3 as described above, and has a length substantially half that of the pulleys 3, 3. At two positions, they are connected to leading runners 7, 8 as shown in FIGS.

Since each of the leading runners 7 and 8 is substantially the same in structure, FIG. 4 and FIG.
This will be described specifically based on FIG. 4 is an enlarged perspective view of the leading runner 7, and FIG. 5 is an enlarged front view of the leading runner 7. The leading runners 7 are integrally formed of a synthetic resin having excellent wear resistance, and are located at both ends of the upper surface of the upper guide piece 31 which is formed in an elongated rectangular plate shape in a plan view. A pair of stopper pieces 32a, 32b
And a pair of guide rods 33a, 33b are vertically provided on the lower surface of the upper guide piece 31 at a predetermined distance in the front-rear direction in a region on the front end half thereof.
At the lower end of 33b, a lower guide piece 34 is provided in parallel with the upper guide piece 31.
As is clearly shown in FIG. 2, a mounting piece 35 is suspended so as to form a T-shape with the runner body, and a coil spring 36 is disposed between the stopper pieces 32a and 32b in the runner body. The hanging rod 37 of the curtain K is fixed to 35.

The length of the coil spring 36 in a state where no tension or compression force is applied is equal to the length of the two stopper pieces 32.
a, 32b are formed to be shorter than the length between them, and at both ends, stop rings 36a, 3 connecting the respective ends of the loop-shaped string 5
6b, and each of these retaining rings 36a, 36b
Each end of a loop-shaped string 5 having holes 32c of stopper pieces 32a and 32b passed therethrough.

When the loop-shaped string 5 is connected to the coil spring 36, the coil spring 36 is in a state of being extended by a predetermined length, and when the loop-shaped string 5 is pulled in either direction, a stop ring is provided. 36a or 36b abuts against the stopper piece 32a or 32b to restrict its movement area, so that relative movement between the loop-shaped string 5 and the leading runner 7 is allowed only between the stopper pieces 32a and 32b. . It is needless to say that an elastic member such as rubber can be used instead of the coil spring 36.

The hanging rod 37 is made of metal and is shown in FIG.
As shown in FIG. 5, it is bent at predetermined intervals at two points in the intermediate portion, and both ends are formed so as to extend in opposite directions and parallel to each other. The base end portion is fixed to the mounting piece 35 with a set screw 37b in a state of projecting from the side to the front side, and the hanging member 37c of the curtain K is locked in the hole 37a as shown in FIG. It is.

The leading runner 7 is shown in FIGS.

The guide rails 3a and 33b are slidably fitted on the guide rail main body 1 in a state where they are located in the guide grooves 1a of the guide rail main body 1. In the process of moving along the guide rail body 1, the leading runner 7 mainly swings left and right with respect to the guide rail body 1 by the guide rods 33a and 33b, and guide rails by the upper guide piece 31 and the lower guide piece 34. The upward and downward swinging of the main body 1 is mainly controlled.

The leading runner 8 differs from the leading runner 7 only in that the hanging rod 37 of the curtain K attached thereto is shorter than that of the leading runner 7 and hardly protrudes from the leading end side of the runner body. The configuration is substantially the same, and the guide rail body 1 is slidably fitted in the opposite direction, that is, left and right symmetrical. C
Are caps detachably fitted to both ends of the guide rail body 1.

FIG. 6 shows the operation of the first embodiment.
The operation will be described with reference to the operation explanatory diagrams shown in FIGS. When the curtain K is in a stationary state, the coil spring 36 provided on each of the leading runners 7 and 8 is generally located substantially in the middle between the stopper pieces 32a and 32b as shown in FIG. , 36b are stopper pieces 32a,
32b is maintained in a non-contact state.

Now, with the curtain K closed, the user holds one of the curtains in his hand and pulls it in the opening direction, as shown in FIG. At that moment, the loop-shaped string 5 is pulled on one side of the pulley 3 by the rotation of the pulley 3 and slightly relaxed on the other side, so that the leading runners 7 and 8 are pulled.
, The coil springs 36 are respectively extended, the stop ring 36b moves to a position where it abuts against the stopper piece 32b, and starts to move integrally with the leading runners 7, 8 at that position. It will be opened to the right.

On the other hand, when closing the curtain K as shown in FIG. 6B, when one of the curtains is held in hand and pulled in the closing direction, the pulley 3 rotates to rotate the loop-shaped string 5, The loop-shaped string 5 is pulled on one side by the rotation of the pulley 3 and slightly relaxed on the other side. As a result, the coil springs 36 are extended in the leading runners 7 and 8, respectively, and the stopper ring 36a abuts against the stopper piece 32a. The curtain K is moved to the position, and starts moving integrally with the leading runners 7 and 8 at that position, and the curtains K on both sides are simultaneously closed.

That is, at the moment when the curtain K is pulled, the coil spring 36 expands, and the shock applied to the loop-shaped string 5 is reduced, so that the life of the loop-shaped string 5 can be extended. Also, while the curtain K is being closed and opened, the loop-shaped string 5 is connected to the coil spring 3.
The slack is absorbed by the contraction force of No. 6, and the tension is maintained. Moreover, since the loop-shaped string 5 itself is also formed of a material having extremely low elasticity such as a wire or Kevlar fiber, there is little slack that occurs over time, and the elastic strength and length of both coil springs 36 are set appropriately. By doing so, tension can be maintained without sagging for a long time.

Such a guide rail body 1 has a pulley 3 and a roller 6 attached thereto in a factory, a loop-shaped string 5 is wound around the pulley 3, and leading runners 7, 8 and a floating runner 9 are attached to the guide rail body 1. The pulleys 3 and 3 are positioned so that the sliding fit and the loop-shaped string 5 have an appropriate tension.
Shipped as a whole in assembled state.

At the time of shipping, as shown in FIG. 7, the sheet is folded in two by a butterfly board 11, packed in a box in a shortened state, or packed and shipped. When folded into two, the loop-shaped string 5 is pulled more strongly. The loop-shaped string 5 is connected to a coil spring 36 as an elastic member of the leading runners 7 and 8 in the middle thereof. Due to the extension of the coil spring 36, the increase in the tension of the loop-shaped string 5 due to the bending is alleviated, so that a large tightening force can be prevented from acting on the pulley 3. In addition, it is not bulky at the time of transportation, so that the transportation cost can be reduced.
By extending the connecting portion by 1, the end surfaces of the guide rail main body 1 abut against each other and extend straight, so that the mounting can be immediately performed. Note that leather, a soft synthetic resin plate, canvas, or the like may be used instead of the butterfly plate 11 as the connecting tool.
It is desirable that the thickness of these connecting members be equal to or less than the thickness of the cap C so as not to cause inconvenience in mounting the guide rail body 1.

(Embodiment 2) FIG. 8 is a perspective view showing the structure of a guide rail for a manually opened / closed curtain according to Embodiment 2, and FIG. 9 is an enlarged sectional view taken along line IX-IX of FIG. In the second embodiment, the hook 12a attached to the leading end of the drawstring 12 is engaged with the hole of the hanging rod 37 of the curtain K in the leading runner 8, and is hung as it is. Other configurations are substantially the same as those of the first embodiment, and corresponding portions are denoted by the same reference numerals and description thereof is omitted.

In the second embodiment, in addition to the functions and effects of the first embodiment, the fabric of the curtain K can be damaged as compared with a case where the curtain K is directly held and opened and closed. In addition, it is possible to prevent the curtain K from being stained. Further, when the curtain K is closed, the drawstring 12 has a hanging rod 37 of the leading runner 7 on its front surface.
Since the long extended end portion is located, it is covered by the curtain K and is concealed from the outside, which is desirable in appearance.

The coil spring 14 can be moved relative to the operation string 13 by its own weight. When one side of the operation string 13 is pulled to open and close the curtain K, the other side moves upward. 14 moves relative to the operation string 13 by its own weight, and is always located at the lowermost end, so that the operation string 13 can always be given an appropriate tension state. In the case where a wooden or metal donut-shaped member made of wood or metal is passed through the operation string 13 instead of the coil spring 14, the operation string 13 is prevented from being twisted due to the contact with the curtain K. Therefore, a similar effect can be obtained.

In the third embodiment, in addition to the operation and effect of the first embodiment, the curtain K is simultaneously opened by pulling one of the operation cords 13 on one side of the window. By pulling the other, the curtain K is simultaneously moved in the direction in which it is closed. In addition, when the operation string 13 is released when the opening and closing operations are completed, the tension is maintained by the gravity of the coil spring 14, and the operation string 13 is loosened and hangs downward from the guide groove 1 g of the guide rail body 1. The unsightlyness is eliminated.

Further, the operation cord 13 is extended parallel to one end of the guide rail main body 1 in parallel with the guide rollers 15a and 15b and is led out below the guide rail main body 1 in parallel. As a result, the user is always kept in a parallel state with respect to the user who has headed for the curtain K, and the strings on both sides are twisted, and it is not known which side should be pulled. Can be prevented. Other configurations and actions,
The effect is substantially the same as that of the first embodiment. Corresponding portions have the same reference characters allotted, and description thereof will not be repeated.

In the first to third embodiments, the guide rail body 1 for the curtain is divided into two parts. However, it is needless to say that the guide rail body 1 may be divided into many parts. Further, in the first to third embodiments, the case where the present invention is applied to the guide rail for the curtain of the window is shown. However, the present invention can be applied to the guide rail of the curtain of the theater and the like, and other guide rails curved in an arc shape. Needless to say. The weight according to claim 5 is preferably a donut shape on the interior of the room, but the coil spring may be colored in the same color as the operation string 13 so as to be inconspicuous.
