Description

The present invention relates to a curtain opening and closing device.

The proposal shown in patent documents 1-3 is made about applying the reel using a mainspring about the curtain, especially the curtain which opens and closes in the horizontal direction.
Patent Document 1 discloses a shower curtain in which a base end of a synthetic resin film is fixed to a winding shaft in a storage box so that the shower curtain can be stored in the storage box. The proposal of Patent Document 1 is such that the entire curtain is wound up in a storage box, and it is difficult to apply it to the opening and closing of a normal curtain.

Patent Document 2 is a tying tool used for tying up curtains provided in openings such as windows and sweeping-out, and this tying tool is used for tying up curtains, and a tying band used for tying up curtains. The present invention discloses a curtain tying tool including a rotary winding device wound so as to be able to be drawn out and rolled up. The proposal of Patent Document 2 is an improvement relating to a means for binding the curtain, and is not related to the opening and closing of the curtain itself.

In Patent Document 3, a hook for hanging a reel is hung on a runner that suspends a curtain, a long body coming out of the reel is pulled out, connected to the upper end on the leading edge side of the curtain, set, and awakened. An opening device is disclosed in which a curtain is opened by detecting a sound sensor when a clock alarm is sounded and operating a reel to wind up a long body. The opening device is set in the above-described manner with respect to the closed curtain. Therefore, it is extremely difficult to open the curtain while the apparatus is attached to the opened curtain. More specifically, this opening device suspends the reel from the runner at the upper end of the curtain, which is higher than the person's back, and the long body cannot be pulled out stably. The front end of the scale is attached to the upper end on the front end side of the curtain. Therefore, it is practically impossible to move the curtain so that the curtain is pulled open with the front end of the elongated body attached to the upper end on the front end side of the curtain. Also, if you pull the long body attached to the upper end of the curtain, you can pull out the long body along with the curtain, but the reel is suspended from the runner at the upper end of the curtain, which is higher than the person's back. It is necessary to perform the operation of closing the curtain by extending it upwards, and it is difficult to smoothly pull out the long body from the reel.

(Outline of the first embodiment)
A first embodiment will be described with reference to FIGS.
The curtain opening and closing device according to this embodiment opens and closes the curtain 11 semi-automatically.
The fixed side portion 13 is a portion that maintains a fixed state with respect to the moving curtain 11, and includes a building such as a wall surface of an indoor window side and an attachment member such as a curtain rail 14 fixed to the building. The curtain 11 includes a curtain cloth 16 and a runner 15 (shown in FIG. 3) that hangs the curtain cloth 16 and travels along the curtain rail 14.

The curtain rail 14 is usually fixed along the upper side of the window side, but technically it is not necessary to be limited to this and can be used for a wall surface without a window. In this figure, the base end side of the curtain 11 is the left side, the tip side is the right side, the right side (base end side) is moved to the right, the curtain 11 is closed, and the curtain 11 is opened to the left.

The curtain opening / closing device includes a reel 21 that winds up a long body 22 such as a string, a thread, or a belt by the action of a built-in spring (not shown), and the interlocking portion 23 provided on the long body 22 is curtained. 11 is a device that opens and closes the curtain 11 semi-automatically. In the example of FIG. 1, when a person closes the curtain 11, the free end of the long body 22 is pulled down. At this time, it is also preferable to provide the gripping portion 26 at the free end of the long body 22 so that it can be easily pulled down. By pulling out the long body 22, the interlocking unit 23 moves and closes the curtain 11.

When the curtain 11 is opened, the long body 22 is wound up by the stored spring force. As a result, the interlocking portion 23 provided on the long body 22 moves the curtain 11 to open the curtain 11.
In this way, the curtain opening / closing device moves the curtain 11 to one of open and closed by human power, and moves the curtain 11 to the opposite (closed and open) by the spring force. The curtain 11 is opened and closed semi-automatically.

(Arrangement structure)
A specific arrangement structure of the curtain opening / closing device will be described with reference to FIG.
First, as shown in FIG. 1A, a reel 21 is attached to one end side (left end side in this example) of a curtain rail 14 extending in the left-right direction. A long body 22 is partially wound around the reel 21, and the free end (tip) side of the long body 22 is drawn out to the outside. The drawn long body 22 is folded back at the folding portion 25 arranged slightly closer to the right end than the middle of the curtain rail 14 and returned to the left end. A guide portion 24 is disposed at the left end, and the long body 22 hangs down from the horizontal state to the vertical state by the guide portion 24. A grip portion 26 is provided at the free end (lower end) of the long body 22.

In order to reduce resistance, it is desirable to use a rotor such as a pulley or a roller at the turning portion of the folding portion 25 or the guide portion 24. It can also be used as the guide part 24. Further, the reel 21, the folded portion 25 and the guide portion 24 may be fixed to a wall surface or the like, but it is appropriate to be provided on the curtain rail 14, and in particular, to be mounted so as to be placed on the curtain rail 14. It is. It is desirable that the guide portion 24 be formed integrally with the reel 21 so that the actual attachment is sufficient if two members of the reel 21 and the folded portion 25 are attached. Further, the reel 21 and the folded portion 25 may be fixed in advance to a plate material or the like and attached to the curtain rail 14 together with the plate material. Further, in addition to the curtain rail 14, it may be attached to a curtain box.

(About the interlocking unit)
An interlocking portion 23 is provided in the forward path of the long body 22 (between the reel 21 and the folded portion 25). The interlocking portion 23 is attached to the upper portion of the leading end side (the right end side in FIG. 1) of the curtain 11, thereby fixing the leading end side of the curtain 11 to the long body 22. As the interlocking part 23, a part having a clip-like structure can be used, and an example in which the upper end of the curtain cloth 16 is pinched and fixed at the holding part of the clip to be opened and closed can be exemplified. Moreover, the string fixed to the long body 22 can also be used as the interlocking | linkage part 23, and this string may be tied through the ring of the runner 15, etc. Moreover, you may use the ring which opens and closes as the interlocking | linkage part 23. FIG. In any case, the interlocking portion 23 may be anything that can fix the tip side of the curtain 11 to the long body 22 so as not to move. However, the curtain 11 (particularly the curtain cloth 16) is washed or replaced. In consideration of the above, a thing that can be detachably fixed to the curtain 11 is suitable. The interlocking unit 23 may be connected to the curtain cloth 16 or connected to the runner 15.

In the example of FIG. 1, the rotation axis of the reel 21 and the folded portion 25 is drawn substantially horizontally so that the forward path is arranged below the return path, but at least one of the two is drawn. You may arrange | position so that one rotation axis may become substantially perpendicular | vertical.
Although not shown, a right curtain is disposed on the right side of the curtain rail 14. The right curtain can be provided with a curtain opening / closing device, and the right curtain can be provided without a curtain opening / closing device. Alternatively, instead of using a pair of left and right curtains, only one curtain may be used for the curtain rail 14.

(State of FIG. 1 (A))
The state of FIG. 1A is a state in which the curtain 11 is closed by about half, and the interlocking portion 23 is attached to the upper part of the right end side of the curtain 11.
The curtain 11 is in a state in which it is closed about half from the fully opened state (the state of FIG. 1 (D) approached to the left end side of the curtain rail 14), and in the fully opened state The interlocking part 23 is located closer to the left end. Then, when the person pulls down the free end (gripping portion 26) of the long body 22 by hand, the long body 22 is unwound from the reel 21 and the interlocking portion 23 moves to the right and is connected via the interlocking portion 23. The curtain 11 is closed. With the curtain 11 closed to an appropriate position, the person slowly releases his / her hand from the gripping portion 26, so that the reel 21 is locked with the elongated body 22 wound up slightly, and the curtain 11 is in a half-open state. can do.

(State of FIG. 1 (B))
FIG. 1B shows a state in which the curtain 11 is completely closed. The right end of the curtain 11 moves to the approximate center of the curtain rail 14, and the long body 22 is also pulled out accordingly. The curtain 11 is stopped in this state in the same manner as described above, and when a person slowly releases his / her hand from the gripping portion 26 in a state where the long body 22 is pulled out (state shown in FIG. 1C), The reel 21 is locked in a state where the long body 22 is wound up slightly, and the curtain 11 can be fully closed (the state shown in FIG. 1B).

(State of FIG. 1C)
FIG. 1C shows a state for opening the curtain 11. The reel 21 is configured so that when the long body 22 is wound, the long body 22 is automatically wound by pulling out the long body 22 a little by the excessive length and releasing the hand. It is well known (Japanese Patent No. 4590, opening portion 1 interlocking portion 23, Japanese Patent Laid-Open No. 53-66583, Japanese Utility Model Publication 62-43973, Japanese Utility Model 4-spring spring 860, etc.). The one having the same structure as this is used.

Specifically, the guided portion of the stop lever attached to the drum slides while being guided by the guide groove provided in the case, so that the drum is rotated, stopped, and reversely rotated. Is.
More specifically, a drum around which the long body 22 is wound is rotatably mounted in the case, and the drum is biased in the winding direction of the long body 22 by a spring. Yes, the long body 22 pulled out against the mainspring is automatically wound by the action of the mainspring. At that time, after the long body 22 is pulled out, the hand is slowly released (in other words, the pulling is stopped while holding the long body 22). Then, after the long body 22 is slightly wound by the mainspring, it is locked and stops at that length. On the other hand, at the time of winding, the long body 22 is pulled out a little by the surplus length. And it is designed so that the long body 22 may be automatically wound by releasing the hand. Therefore, in order to wind up the long body 22 with the reel 21, the long body 22 is redundant by an extra length (specifically, about 5 to 10 cm) as compared with the fully closed state of FIG. Need to pull out. FIG. 1 (C) shows this state, and the folded portion 25 is arranged on the left side more than the surplus length.

The distance between the reel 21 and the folded portion 25 may be set longer than the distance obtained by adding the surplus length to the expected opening / closing length of the curtain 11, and may extend to the entire length of the curtain rail 14. .
As a result, a person can pull the grip 26 of the long body 22 and pull out the long body 22 from the reel 21 a little (excess length) (small arrow in FIG. 1C). Then, immediately after the pull-out, the long body 22 is wound around the reel 21 by releasing the hand from the grip portion 26, the interlocking portion 23 moves to the left end of the curtain rail 14, and the curtain 11 is fully opened. And

(Summary of operation)
As described above, the curtain opening / closing device of this example can close the curtain 11 by a person pulling on the free end of the long body 22, so that the person can pull the long body 22 without pulling the curtain 11. The curtain 11 is closed by being pulled by the provided interlocking portion 23. Then, by slowly releasing the hand after pulling the long body 22, the long body 22 is slightly wound around the reel 21, and then the rotation of the reel 21 is locked and the long body 22 stops. The curtain 11 can be opened to a desired position. To close the curtain 11, when the hand is released immediately after pulling the long body 22 by the excessive length, the long body 22 is wound around the reel 21, and the interlocking portion 23 reaches the left end of the curtain rail 14. The curtain 11 is fully opened. Thereby, the curtain 11 can be opened and closed without directly touching the curtain 11, and the curtain 11 is opened and closed semi-automatically.

In the above description, the force stored in the mainspring of the reel 21 is used when the curtain 11 is opened. Conversely, the force stored in the mainspring of the reel 21 may be used when the curtain 11 is closed. it can. At this time, the left and right positions of the reel 21 and the turn-back portion 25 may be interchanged, but the positions of the reel 21 and the turn-back portion 25 remain the same as in FIG. 1, and only the interlocking portion 23 is provided on the return path. When the curtain 11 is closed, the force stored in the main spring of the reel 21 can be used. Specifically, in the state of FIG. 1D (a state where the reel 21 winds up the long body 22), the curtain 11 is fully closed, and the interlocking unit 23 is connected to the right side thereof. The interlocking portion 23 is provided at a position near the folded portion 25 at the right end of the reel 21 on the return path.

In this example, the forward path and the return path of the long body 22 are arranged side by side. Correspondingly, two folding rollers 29 are arranged on the folding section 25 at the front and back. The scale 22 is changed in direction by 90 degrees by the front folding roller 29, and then changed by 90 degrees by the subsequent folding roller 29, whereby the direction of the insertion portion 180 degrees is changed. .

The reel 21 is provided on a fixed plate 27, and the fixed plate 27 is passed over the front and rear curtain rails 14 so that the reel 21 is fixed to the curtain rails 14 in a stable state. Further, when the long body 22 slides, a force is applied to the reel 21 and the guide portion 24 so that they are lifted up. It is also preferable that the fixing plate 27 and the curtain rail 14 are fixed.

As the interlocking portion 23, a clip provided at the lower end of the string and the upper end of the string fixed to the long body 22 is used. The curtain 11 (runner 15 or curtain cloth 16) is attached to the clip, and the curtain 11 and the long body 22 are connected.

(Outline of the second embodiment)
Next, a second embodiment will be described based on FIG.
In the first embodiment, an example in which one curtain 11 is opened and closed by one curtain opening and closing device has been shown. In the second embodiment, a pair of left and right curtains 11 are simultaneously opened and closed by one curtain opening and closing device. It is a thing.
The second embodiment is a partial modification of the first embodiment. The same components are denoted by the same reference numerals, and detailed description thereof is omitted.

(Main changes)
In the second embodiment, the curtain opening / closing device is arranged over substantially the entire length of the curtain rail 14, the reel 21 and the guide part 24 are arranged at the left end, and the folding part 25 is arranged at the right end. is there. The left and right positions can be changed.

Further, the forward path and the return path of the long body 22 are arranged side by side in the horizontal direction, and the reel 21 and the folded portion 25 are arranged so that the rotation axis of the pulley is substantially vertical. And the interlocking | linkage part 23 is provided in each of the outward path | route of this elongate body 22, and the return path | route, the interlocking | linkage part 23 of an outward path | route is connected to the right side of the left curtain 11, and the interlocking | linkage part 23 of a return path is the left side of the right curtain 11 Connected to the side.

(About operation)
The opening / closing operation of the curtain 11 is substantially the same as that of the first embodiment. In particular, the left curtain 11 performs the same movement.
4 (A) and 4 (B) correspond to FIG. 1 (A), and the curtain 11 is shown in a half-open state. In this example, since the forward path and the return path of the elongated body 22 are arranged in the lateral direction (front-rear direction), a front view is shown in FIG. 4 (A) and a plan view is shown in FIG. 4 (B). is there. 4C to 4F are plan views, and the state of the curtain 11 is indicated by a thick arrow.

4C corresponds to the state of FIG. 1B, FIG. 4D corresponds to the state of FIG. 1C, and FIG. 4E corresponds to the state of FIG. .
The right curtain 11 moves symmetrically with the right curtain 11 only in that the forward path and the return path of the long body 22 are changed. Specifically, the curtain 11 on the right side is in the fully opened state and is positioned near the folded-back portion 25 at the right end, and the interlocking portion 23 provided in the return path on the left side (tip side) of the curtain 11. Is connected. Then, by pulling the grip portion 26 of the long body 22, the interlocking portions 23 of the forward path and the backward path move and approach each other, and the left and right curtains 11 are closed.

As described above, the reel 21 pulls out the long body 22 a little (excess length), and the part retracts and stops. Therefore, as shown in FIG. 4C, when the runners 15 (shown in FIG. 6) of the left and right curtains 11 stop at the center, the interlocking parts 23 retreat from each other, and the left and right curtains 11. There may be a slight gap between them. Therefore, by providing the interlocking portion 23 with a stretchable portion such as a rubber string or a coil spring, even if the runners 15 of the left and right curtains 11 collide with each other at the center, the long body 22 has an excessive length. Can be pulled out (see FIG. 4D). Moreover, the example shown in FIG. 8, FIG. 9 mentioned later is also employable.

Moreover, as shown to FIG. 4 (F), you may make it avoid the interference of runners 15 by separating the curtain rail 14 for every curtain 11 on either side.
Even in this example, the curtain 11 can be closed rather than opened by the force of the spring 21 of the reel 21.

(Specific example according to the second embodiment)
5 and 6 show the example of FIG. 4 more specifically, and the description will focus on the parts not described in FIG. Also in this example, two curtain rails 14 are arranged at the front and rear, and different types of curtains 11 such as a thick cloth curtain and a lace curtain are suspended. The curtain rail 14 is fixed to a wall surface or the like by mounting brackets 17 at the left, right, and center.

Also in this example, the folding | returning part 25 is passed on the front and back curtain rail 14, and the both front and back ends of the folding | returning part 25 are supported by each curtain rail 14. FIG. In this example, two folding rollers 29 are arranged at the top and bottom of the folding unit 25 so that the direction of the insertion portion 180 degrees is changed vertically, but as in the previous example, The long body 22 may change the direction of the forward path and the backward path.

The interlocking portion 23 is provided on each of the long and long bodies 22 on the forward path and the return path, the upper end of the string is fixed to the long body 22, and the clip on the lower end of the string is the left and right curtains 11 (runner 15 or curtain cloth 16. ) Is attached.

(Outline of the third embodiment)
In the previous two embodiments, when the curtain 11 is opened or closed by a human hand using the folded portion 25 or the guide portion 24, the free end (gripping portion 26) of the long body 22 is lowered. Although an example that can be performed by pulling has been shown, in this embodiment, when the curtain 11 is opened or closed by a human hand without using the folding portion 25 or the guide portion 24, the normal curtain is opened and closed. In this manner, the curtain 11 is opened or closed by moving left and right.

In the previous two embodiments, the curtain opening / closing device is provided at the upper part of the curtain 11. In this example, the curtain opening / closing device is provided at an intermediate position in the vertical direction of the curtain 11.
In the third embodiment, the same reference numerals are given to substantially the same configurations as those in the previous embodiment, and the detailed description thereof is omitted.

(Characteristic configuration of the third embodiment)
In this embodiment, the reel 21 is fixed to a fixed side portion 13 (for example, a wall surface at the window) at an intermediate position in the vertical direction of the curtain 11. The fixing method is not particularly limited, and screws, nails, double-sided tape, or the like can be used.

An interlocking portion 23 is attached to the free end of the long body 22. This interlocking part 23 can adopt a clip-like one as in the previous example, and is connected to an intermediate position in the vertical direction of the curtain 11. The intermediate position where the long body 22 and the reel 21 are provided is a position where a person can easily hold it by hand, and it is desirable that the intermediate position be within the reach of the hand without bending.

In addition, a grip portion 26 is provided at the free end of the long body 22 together with the interlocking portion 23. The interlocking portion 23 and the gripping portion 26 can be provided separately, but can also be formed integrally.
When the curtain 11 is closed, a person pulls the holding part 26 to the side, whereby the interlocking part 23 is drawn out from the reel 21 and the force is stored in the mainspring. FIG. 7A shows a state where the curtain 11 is half-opened, and corresponds to FIGS. 1A and 4A and 4B of the previous example. The reel 21 itself when opening and closing the curtain 11 is the same as in the previous example. By slowly releasing the hand while the long body 22 is pulled, the reel 21 winds up the long body 22 slightly. The long body 22 is completely wound up and the curtain 11 is fully opened by releasing the hand immediately after pulling the excess length. The difference from the previous example is that the movement of the hand of the person pulling the grip portion 26 causes the curtain 11 to be pulled almost directly, which is the same procedure as closing the curtain with the hand of the person.

FIG. 7B shows a state in which the curtain 11 is fully opened by the force of the spring 21 of the reel 21. In this embodiment, in order to bundle the curtain 11 at the window from this state, the curtain side engaging portion 31 is provided at the free end of the elongated body 22 and is detachable from the curtain side engaging portion 31. The reel 21 engaging portion 32 to be connected is provided on the reel 21.

Although this curtain side engaging part 31 can also be implemented as a separate member from the grip part 26, in this example, the curtain side engaging part 31 and the grip part 26 are shared by one member. Specifically, by carrying out the ring-shaped part as the gripping part 26 and curtain side engaging part 31, when a person pulls, the gripping part 26 that is a ring-shaped part can be pulled and the reel side By making the engaging portion 32 into a hook shape, the curtain side engaging portion 31 that is a ring-shaped part can be detachably connected to the reel side engaging portion 32 (FIG. 7C )reference).

In addition, the curtain side engaging part 31 and the reel side engaging part 32 may be detachably connected. For example, the curtain side engaging part 31 and the reel side engaging part 32 may be a hook and an annular belt. It may be a connection.
Although the right curtain 11 is not shown in FIG. 7, the curtain opening / closing device of the third embodiment can be adopted for each of the left and right curtains 11. At that time, a connecting member using a magnetic force such as a magnet is provided in the interlocking portion 23, the gripping portion 26, or the curtain side engaging portion 31, so that the left and right curtains 11 can be fixed to each other in a closed state. May be.

(Specific example according to the third embodiment)
8 and 9 show the example of FIG. 7 more specifically, and the description will focus on the parts not described in FIG.
In this example, the interlocking portion 23 is composed of one long body side member 33 and two curtain side members 34.

The long body side member 33 is fixed to the long body 22 and moves together with the long body 22.
Each of the curtain side members 34 includes an insertion portion 35 and a connection portion 36. The insertion portion 35 has a ring shape or the like through which the long body 22 can be slidably passed. The ring-shaped insertion portion 35 is formed smaller than the long body side member 33. As a result, the insertion part 35 does not move even when the long body 22 moves, but the insertion part 35 is pushed together with the long body side member 33 so as to be pushed by the long body side member 33 fixed to the long body 22. Moving. The connecting portion 36 is detachably fixed to the curtain 11 such as a clip. However, the connecting portion 35 may be fixed to the curtain 11 so as not to be detachable by attachment or the like. In this manner, the curtain side members 34 of the reel side engaging portions 32 are fixed to the curtain 11 at intervals, and the long body 22 is passed through the long body side member 33 between them.

Thus, when the person pulls the grip portion 26 from left to right by hand and closes the curtain 11 while pulling out the long body 22, the curtain side member 34 on the side far from the reel 21 (right side in this example) is extended. The front end side of the curtain 11 is moved so that the scale member 33 is pushed. Then, when the drawing is finished and the hand is slowly released from the gripping portion 26, the excessive length of the long body 22 is rewound and stopped as described above. At that time, since the elongate body side member 33 is slidable with respect to the insertion portion 35 of the curtain side member 34, the elongate body side member 33 is basically moved without moving the curtain side member 34 (although it may move slightly due to frictional resistance). In the free state), only the long member 33 moves to the left as the long member 22 moves. As a result, the curtain 11 can be kept closed.

Next, when opening the curtain 11, the curtain 11 is wound around the reel 21 by pulling out the grip portion 26 more than the surplus length and suddenly releasing the hand, as described above. At that time, the elongate body side member 33 fixed to the curtain 11 moves so as to push the curtain side member 34 on the side close to the reel 21 (the left side in this example), whereby the curtain 11 is closed.

In the figure, the space between the left and right curtain-side members 34 is greatly illustrated, but it is sufficient if there is an interval of about the extra length.
This structure can also be applied to the first and second embodiments described above. At that time, one curtain side member 34 may be connected to the front end side of the curtain 11, and another curtain side member 34 may be connected to a position in the vicinity thereof. The connection portion 36 may be connected to the runner 15 or the curtain cloth 16, but when attached to the runner 15, the connection portion 36 (curtain side member) is connected to the runner 15 on the tip side of the curtain 11 and the runner 15 adjacent thereto. 34) is most preferable, and if implemented in this way, the reel 21 does not have to be provided with an extendable portion such as a rubber string or a coil spring as described above. It is possible to absorb the surplus length necessary to stop the operation.
