[0001]

[Industrial application] The present invention connects a leading car that locks the upper end of the curtain to a string, a wire, a ball chain, and other power transmission members for opening and closing the curtain that move in the passage of the curtain rail. Then, the present invention relates to an improvement of the curtain opening / closing device that opens and closes the curtain by moving the power transmission strip.

[0002]

2. Description of the Related Art Conventionally, in a curtain opening / closing device that opens and closes a curtain by moving a string or other power transmission strip, as a curtain rail, for example, as shown in Japanese Utility Model Laid-Open No. 60-108284, an upper rail cover is used. There has been a shape in which two passages of power transmission strips are symmetrically arranged side by side on the left and right sides of the central vertical plate portion between the holding portion and the lower runner suspension portion.

As the leading car, the above-mentioned actual Kai 60-1
As described in Japanese Patent Publication No. 08284, a leading vehicle main body portion slidably provided on a runner suspension portion is provided with a guide / bar member locking member and a power transmission member member movable in a passage of a curtain rail. There was one in which the hook portion was integrally formed.

Further, as a curtain rail 1 of a similar curtain opening / closing device, there is also a curtain rail having no central vertical plate portion as shown in FIG. .

[0005]

In the conventional curtain opening / closing device, the passages for the power transmission strips of the curtain rail are symmetrically arranged side by side as described above. (B) Therefore, when it is necessary to hang the curtain in a curved state in the horizontal direction, for example, in the case of a curtain opening / closing device such as a balcony, bay window, or partition of a patient room, the curtain rail needs to be curved in the horizontal direction. However, it was impossible or difficult to bend in the horizontal direction with the shape in which the passages were symmetrically arranged side by side.

If the curtain rail is forcibly curved with a large force, the sectional shape of the passage is deformed, and the power transmission strip cannot move smoothly. Therefore, in order to bend the curtain rail in the horizontal direction, it is necessary to fit the shape-retaining strip 13 into the passage 5 of the curtain rail 1 as shown in FIG. However, it was inconvenient because the operator could not bend it into the required curved shape at the installation site of the curtain opening / closing device.

Further, in the double-opening curtain opening / closing device, each power transmission member inserted in each passage of the curtain rail is
It is necessary to lock the top car respectively. However, in the case where the passages are symmetrically arranged side by side on the left and right sides of the curtain rail, both leading cars are provided on the front side and the back side of the curtain rail. Therefore, the back side of one of the leading cars can be seen, and the appearance in the mounted state is bad (for example, see Japanese Utility Model Laid-Open No. 60-108284).

[0008] Further, if the passages are merely arranged in two steps above and below the curtain rail, the leading car is hooked to the upper power transmission member and the lower car is connected to the lower power transmission member. The height of the guide / bar material hooking piece that slides in each passage is different. For this reason, the respective leading cars to which the respective guide / bar material retaining pieces are mounted are also mounted at different heights, which is bad in appearance. In addition, even if the guide / bar material retaining pieces with different heights are attached, in order for the leading car to have the same height, it is necessary to make the leading car large in height. There were problems such as getting worse.

The present invention is intended to solve the problems of the conventional curtain opening / closing device. That is, the purpose of the present invention is to allow anyone to easily and quickly bend the curtain rail horizontally at the site where the curtain opening / closing device is installed, and at that time, the cross-sectional shape of the passage of the power transmission member can be changed. It is an object of the present invention to provide a curtain opening / closing device that does not deform and can move the power transmission strip without hindrance. In addition, with the double-opening type curtain opening / closing device, each head car can be easily hooked on each of the two power transmission strips, and the back side of one head car can be seen and the height of both head cars can be seen. The purpose of the present invention is to provide a curtain opening / closing device that is not different and has a good appearance.

[0010]

In the curtain opening / closing device according to the present invention, a power transmission strip 2 for opening / closing the curtain , which moves in the curtain rail 1 , is provided with a leading wheel 4 for hooking a side upper end of the curtain 3. In the curtain opening / closing device which is connected to open and close the curtain 4, the curtain rail 1

It is preferable that 1 is mounted so as to be selectively engageable with the upper and lower two-stage passages 5 (see FIGS. 4 and 5). In the figure, y is a center line in the vertical direction, and each passage 5 and an upper rail held portion 6 are provided.
And a line passing through each center of the lower runner hanging portion 7.

[0013]

The operation state of the curtain opening / closing device according to the present invention is as follows. When it is desired to hang the curtain in a curved state in the horizontal direction, the curtain rail 1 needs to be curved in the horizontal direction as a curtain opening / closing device such as a balcony, a bay window, or a curtain for partitioning a patient's room. In this case, the curtain rail 1 of the curtain opening / closing device according to the present invention is arranged such that the passages 5 are in two stages, upper and lower, as described above, and each of the passages 5 and the upper rail held portion 6 are provided. The centers of the lower runner-hanging portion 7 and the lower runner-suspending portion 7 are formed to be substantially in a line in the vertical direction.

Therefore, this curtain rail 1 is vertically long.
The width is narrow and the cross-sectional shape is different from the conventional one.
With the longitudinally with sufficient rigidity, the rigidity in the lateral direction is small, without requiring a large force to the curvature in the horizontal direction, and easily bent by hand if necessary human
Has become.

[0015] In the case of curving as the curtain rail 1 above, the curtain rail 1 as shown in FIG. 3,
As a reference surface a vertical plane z formed by the center line y which passes through the centers of the passages 5 and the upper rail to be holding portion 6 and the lower runners for hanging portion 7 is bent in the horizontal direction. In that case
This curtain rail 1 is a diagram showing a cross-sectional shape (for example,
As can be seen from FIGS. 1, 2 and 3), the horizontal part
The part to be held 6, which is a
-The ten runner suspension part 7 is formed in the lower part of the lower passage 5.
Has been done. When bending the curtain rail horizontally,
The horizontal portion that exerts the force that deforms the cross-sectional shape of the road 5 is
Unlike the conventional one, a part of each passage 5 is not formed.
Therefore, this curtain rail 1 has a shape-retaining strip (see FIG. 7) that is used when the conventional curtain rail is curved .
(See reference numeral 13) , the cross-sectional shape of each passage 5 is not deformed, so that even in this aspect, the cross-sectional shape can be easily horizontal.
It can be bent and the power transmission strip 2 can be smoothly moved even after bending.

Therefore, unlike the prior art, it becomes possible for anyone to easily and quickly bend the curtain rail horizontally to install the curtain opening / closing device at the construction site for installing the curtain opening / closing device.

In the case of a double-opening type curtain opening / closing device,
The upper and lower two passages 5 of the curtain rail 1 are opened on the same side, and are formed in a continuous manner so as to have a common opening 12 and can slide in the passage 5 while being formed in a continuous manner. It is preferable that the latching piece 11 is provided so as to be selectively engageable with the upper and lower two-stage passages 5.

Now, the two leading wheels 4 to be respectively connected to the two power transmission strips 2 may be attached to the same side of the curtain rail 1, for example, the front side. Then, through the common opening 12 of the upper / lower two-stage passage 5, the guide / bar material locking portion piece 11 engaged with the upper passage 5 in the upward direction is connected to the connecting portion 10 of one of the leading wheels 4. While being mounted, the power transmission strip 2 in the upper passage 5 is pulled out and hooked to the connecting portion 10 (see FIGS. 4 and 6).

Similarly, through the common opening 12, the guide / bar material locking piece 11 that is engaged downwardly with the lower passage 5 is attached to the connecting portion 10 of the other leading wheel 4. The power transmission strip 2 in the lower passage 5 may be pulled out and hooked to the connecting portion 10 (see FIGS. 5 and 6).

In the above case, since the respective leading cars 4 are on the same side of the curtain rail 1, it is unlikely that the rear face of one of the two leading cars can be seen and the appearance is bad as in the conventional case. And the power transmission strips 2 in the upper and lower two-stage passages 5
The work of pulling out and hooking it on the connecting portion 10 of each leading vehicle 4 can be easily performed (see FIG. 6).

Further, since the guide / bar material hooking piece 11 of each leading car 4 is attached to each connecting portion 10 through the common opening 12 of the upper / lower two-stage passage 5, both guide / bar members are provided. The material retaining piece 11 can have the same mounting height to the leading car 4, and even if two leading cars 4 of the same type are used for the upper and lower stages, both leading cars have the same height. It will be attached cleanly (see Fig. 6).

In the curtain rail, as described above, the two passages are in upper and lower two stages, and the respective centers of both passages, the upper rail-holding portion and the lower runner suspension portion are arranged in the vertical direction. The endless power transmission strip 2 is parallel to the upper and lower sides as long as it is formed in a substantially one-row shape. Therefore, unlike the conventional one in which the power transmission strip 2 is parallel on the left and right sides, the power transmission strip 2 is wound around the pulleys (not shown) on both sides of the curtain rail 1 without intersecting, so that the movement can be performed smoothly. Also becomes.

As is apparent from the above, the curtain opening / closing device according to the present invention has the following effects. a Install the curtain opening / closing device horizontally at the construction site
If a curved curtain ray is required, anyone can easily and quickly bend it horizontally, and at that time, the cross-sectional shape of each passage of the power transmission material is not deformed, and power transmission is possible. The movement of the strip can be prevented
It

That is, in the conventional curtain opening / closing device, the two passages of the curtain rail are arranged side by side symmetrically on the left and right sides, and the rigidity in the horizontal direction is great, and it is very difficult to bend them. However, when it was forcibly bent with a large force, the cross-sectional shape of the passage was deformed, and the power transmission strip could not move smoothly. Therefore, it is necessary to fit the shape-retaining strip into the passage and process it into a curved shape in advance at the manufacturer stage.

On the other hand, in the curtain rail of the curtain opening / closing device according to the present invention, the two passages have two upper and lower passages, both passages, the upper rail-holding portion and the lower runner-suspending portion. The centers of and are formed in a shape that is substantially in a line in the vertical direction. Therefore, unlike the prior art, the rigidity in the horizontal direction is small, a large force is not required for bending, the cross-sectional shape of the passage is not deformed, and the power transmission strip can be smoothly moved. Therefore, unlike the conventional case, anyone can easily and quickly bend and install the curtain rail horizontally at the installation site of the curtain opening / closing device as needed.

B In the case of a double-opening type curtain opening / closing device,
If the upper and lower passages of the curtain rail are formed so as to open on the same side, both head cars can be mounted on the same side of the curtain rail, so one of the two head cars The rear surface of the car is not visible and the appearance is good, and the work of pulling out the power transmission strips in the two passages and hooking them on each of the leading cars can be easily performed.

That is, in the conventional curtain opening / closing device in which two passages are symmetrically arranged side by side on the left and right sides of the curtain rail, the power transmission strips on each side are locked to the leading car. It was necessary to attach the car to the front and back of the curtain rail. As a result, the leading car attached to the back of the curtain rail was facing backwards, and the back was visible and the appearance was bad.

On the other hand, in the curtain opening / closing device according to the present invention, the two passages of the curtain rail are arranged in upper and lower two stages and opened on the same side. Therefore, each of the lead wheels to be connected to the two power transmission strips may be mounted on the same side, for example, the front side, and the rear surface of one of the lead vehicles is not visible and the appearance is not as in the conventional case. Further, since the two power transmission members can be pulled out in the same manner and hooked on each leading car, this work can be performed easily and quickly.

C Further, in the case of a double-opening type curtain opening / closing device, the passages that open on the same side in the upper and lower two steps of the curtain rail are formed in a close continuous shape having a common opening,
In addition, if each guide and strip material locking piece that can slide in each passage is provided so that it can be selectively engaged with the upper and lower two-stage passages, each upper and lower two-stage power transmission It is possible to attach the leading cars that are hooked to the strips at the same height and in a good appearance.

That is, when the upper and lower passages are provided on the curtain rail, the guide / bar material engaging piece engaged with the upper passage and the guide / bar material engaging with the lower passage. Since the height is different from that of the pieces, the mounting heights of both leading cars are different. Further, if it is possible to attach the guide / bar material retaining pieces having different heights, the height of the leading vehicle becomes large and the appearance becomes bad.

However, in the curtain opening and closing device according to the present invention according to the present invention, the passages of the curtain rail are opened in the upper and lower stages on the same side, and are formed in a continuous shape having a common opening. Therefore, the guide / bar material locking pieces that are selectively engaged with the upper / lower two-stage passages can be attached through the common openings of both the passages. The mounting parts on the leading vehicle have the same mounting height, so that both leading vehicles can be mounted at the same height without increasing the size.

D As described above, the curtain rail of the curtain opening / closing device has two passages in upper and lower two stages, each passage, an upper rail-holding portion, and a lower runner suspension portion. If the center is formed in a shape that is substantially lined up in the vertical direction, the endless power transmission strip is parallel to the upper and lower sides. Therefore, the power transmission strip can be wound around the pulleys on both sides of the curtain rail without crossing, and can be smoothly moved, unlike the conventional one in which the power transmission strip is parallel on the left and right sides.
