On the leading runner 21 adjacent to
11 is provided. The sandwiching piece 211 is a portion for sandwiching and fitting the engaging piece 10 and is provided toward the engaging piece 10. It is preferable that the sandwiching piece 211 has a shape such that the engaging piece 10 can be easily sandwiched and the sandwiched engaging piece 10 cannot be easily removed.

[0011]

Next, a method of using the electric curtain using the curtain opening / closing device of the present invention will be described.

<A> Electric Curtain Operation When the curtain 40 is electrically operated to open and close, the engaging piece 10 is clamped and fitted to the leading runner 21 as shown in FIG. The fitting method may be carried out by manually pressing the leading runner 21 against the engaging piece 10, or by electrically moving the engaging piece 10 toward the leading runner 21 and pressing it against the leading runner 21. May be. Then, the belt 32 is electrically driven to move the engagement piece 10 in an arbitrary direction. Then, the leading runner 21 combined with the engagement piece 10 moves together with the engagement piece 10, and the curtain 40 can be opened and closed.

<B> Manual curtain operation When the engaging piece 10 and the leading runner 21 are united and the curtain 40 is closed, the curtain 4 is manually operated.
To open 0, the curtain 40 may be grasped and pulled in the opening direction. Then, the sandwiching piece 211 of the leading runner 21 is disengaged from the engaging piece 10, and the curtain runner 20 as a whole becomes free and can be manually moved. Therefore,
Only the curtain runner 20 holding the curtain 40 can be manually moved in the position where the engaging piece 10 remains.
Therefore, the curtain 40 can be opened and closed manually.

[0014]

[Embodiment 2] The drive rope of the engaging piece 10 is not limited to the electrically driven belt 32, and another method may be adopted as long as the engaging piece 10 can be moved along the curtain rail 30. For example, reel members are arranged at both ends of the curtain rail 30, respectively, and a rope material is wound around the reel member to be arranged along the curtain rail 30, and the engaging piece 10 can be attached on the way of the rope material. Then, if the rope member is moved by the rotation of the reel member and the engaging piece 10 is moved, the curtain 40 can be opened and closed electrically and manually as in the first embodiment.

[0015]

Third Embodiment The engaging piece 10 may be formed by providing a convex portion on the surface of the belt 32. At that time, the belt 32 and the engagement piece 10
Since they are integrated, the number of parts is reduced, and the parts cost and the manufacturing cost can be reduced.

[0016]

[Embodiment 4] The leading runner 21 may be provided with a protruding engaging piece, and the belt 32 may be provided with a sandwiching piece that can be fitted to the engaging piece so that the leading runner 21 and the sandwiching piece can be detachably formed. . In that case, the curtain 40 can be opened and closed electrically and manually as in the first embodiment.

[0017]

[Fifth Embodiment] The engaging piece 10 and the leading runner 21 may be configured to be detachable by magnetic force. For example, as shown in FIG. 3, the magnet 213 is installed on the leading runner 21 side, and the magnet 101 is also installed on the engaging piece 10 so that the engaging piece 10 and the leading runner 21 can be combined by magnetic force. . The magnetic attraction force at the time of the combination is set to such an extent that it does not come off due to the movement of the engagement piece 10, but comes off if the curtain 40 is gripped and pulled.
A magnet may be installed on either the leading runner 21 or the engaging piece 10 and a magnetizable metal body may be installed on the other. If the engaging piece 10 and the leading runner 21 are detachable by the magnetic force as described above, the curtain 40 can be opened and closed electrically and manually as in the first embodiment.

[0018]

[Sixth Embodiment] In an electric curtain in which two curtains 40a and 40b can be opened on both sides, a manual curtain operation is also possible. For example, as shown in FIG. 4, a slit 31a is provided along the longitudinal direction on the lower surface of the curtain rail 30a, and the curtain runner 20 similar to the above is attached to the slit in a state of being exposed downward. An endless belt 32 is housed inside the curtain rail 30a so that the curtain rail 30a can be electrically driven along the curtain rail 30a by using a known mechanism. Fix 10b. The engaging pieces 10a and 10b have protruding pieces 111 protruding downward.
Project each. On the other hand, of the curtain runner 20, the leading runner 21 adjacent to the engaging pieces 10a, 10b
A sandwiching piece 211 is provided on each of a and 21b. The sandwiching piece 211 is a portion for sandwiching and fitting the protruding piece 111.

When the curtains 40a and 40b of this embodiment are operated to open and close electrically, the projection piece 111 is clamped by the sandwiching piece 211.
It is clamped and fitted to the engaging piece 10a and the leading runner 21.
a, the engaging piece 10b and the leading runner 21b are combined, and when the belt 32 is driven electrically, the engaging pieces 10a and 10b move in opposite directions, so that the curtains 40a and 40b open and vice versa. Driving the belt 32 in the direction closes the curtains 40a and 40b. In this way, the curtains 40a and 40b can be opened both sides electrically.

On the other hand, when the engaging pieces 10a, 10b and the leading runners 21a, 21b are combined, the curtain 40
When a and 40b are closed, the curtain 40 is manually
If you want to open a, 40b, curtain 40a or 4
You can grab 0b and pull it in the opening direction. Then, the projecting piece 111 of the engaging piece 10a or 10b is disengaged from the sandwiching piece 211, and the curtain runner 20 becomes free.
Therefore, the curtains 40a and 40b can be opened and closed manually.

[0021]

[Embodiment 7] The engagement piece may be fixed to the belt by a fitting method. For example, as shown in FIG. 5, a tooth portion 321 is provided on the side surface of the belt 32a, and the engaging piece 10c is attached to the tooth portion 3 thereof.
21 is formed into a U-shaped cross-section having a toothed portion 112 fitted on the inner surface thereof, and a protrusion 11 is provided on the outer surface thereof. Therefore, the engagement piece 10c is a fitting type from above the belt 32a and can be attached to and detached from the belt 32a. Belt 32a
Since the engaging piece 10c fitted in and the leading runner 21 are detachable similarly to the first embodiment, it is possible to electrically and manually open and close the curtain.

[0022]

[Embodiment 8] The belt 32 that serves as a drive rope and the leading runner may be detachable by pressure contact. That is, as shown in FIG. 6, a protrusion 322 is provided in the middle of the belt 32, and a recessed groove 214 fitted to the protrusion 322 is formed on the leading runner 21c.
Is engraved so that the leading runner 21c can be attached and detached at the position of the protrusion 322. The shapes of the protrusion 322 and the concave groove 214 are not limited to the curved shapes as shown in FIG. 6, but may be different shapes as necessary. In addition, as shown in FIG. 7, if the protrusion 322 is formed of a plate-shaped member made of a material different from that of the belt 32 and has elasticity with respect to the contact of the leading runner 21c, the protrusion 3
The wear of 22 itself can be prevented.

When the protrusion 322 is formed by attaching another member to the surface of the belt 32, the engaging piece 10c of the seventh embodiment is formed.
In some cases, it may be formed as a fitting type.

[0024]

Since the present invention is as described above, the following effects can be obtained.

Although it is an electric curtain, the opening and closing of the curtain can be manually operated. Therefore, the curtain can be opened and closed even when it is not energized, and the operability is extremely excellent.
