Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of an electric curtain opening / closing device that opens and closes curtains by driving a drive motor through a geared cable of a power transmission material, a wire, a timing belt, or the like.

[0002]

[Prior art]

 Conventionally, in many electric curtain type opening / closing devices, for example, endless wires or timing belts are used for the power transmission material. In these, the power transmission strip is wound between the drive pulley or the drive toothed pulley that is rotated by the drive motor on one side of the curtain rail, and the driven pulley on the other side to make a circular movement. Curtains are opened and closed by making them open.

[0003] Recently, an electric curtain type opening / closing device using a geared cable as a power transmission member is increasing. This is because the geared cable has a feature that it can be moved in a curved curtain rail and can be driven by pushing or pulling. This electric curtain opening / closing device is, for example, as described in Japanese Utility Model Application Laid-Open No. 3-105378 filed by the same applicant as the present case, in which the cable cable is not an endless but a free end and is inverted at one side of the curtain rail. In this way, the driving motor provided on one side of the rail meshes with the driving gear that rotates, and the sliding operation opens and closes the curtains.

[0004]

[Problems to be solved by the device]

 However, when the wire or the timing belt is wound around the pulley as the power transmission strip, a large driving force is obtained on the side pulled by the driving pulley or the toothed pulley for driving, but it is reversed to the return side. When it comes to, the driving force due to being pushed by the pulley hardly occurs.

On the other hand, the one using the geared cable as the power transmission member can obtain a particularly large driving force when it is pulled by the driving gear, and also when it is reversed and comes to the return side, A considerable driving force is generated by being pushed by the gear. However, since the geared cable slides in the narrow cable passage hole of the curtain rail, it receives a very large frictional resistance, especially when the drive force is pushed by the drive gear on the inverted return side. The drop was noticeable.

The above-mentioned decrease in driving force of the geared cable is particularly remarkable when a long rail or a rail is bent and used, and it is difficult to move the curtains in either the opening or closing direction. Therefore, in the past, it was considered possible to increase the size of the drive motor and use rails and runners corresponding to it, but the curtain opening / closing device as a whole became large and heavy, and the cost was significantly increased. In addition, there is a problem that the appearance is bad.

The present invention is intended to solve the problems of the conventional electric curtain type opening / closing device. That is, the object of the present invention is to dramatically improve the driving capacity by effectively and effectively using two or more drive motors of the same type in an electric curtain opening / closing device using a geared cable or the like as a power transmission member. It has been improved so that a large driving force can always be obtained without increasing the size of the driving motor, and it is smooth regardless of the moving direction of the power transmission member and whether the rail is long or curved. The goal is to be able to open and close curtains.

[Action]

 According to the electric curtain opening / closing device of the present invention, regardless of the moving direction of each power transmission member, whether the rail is long or curved, the power transmission member always has a large driving force. Because of the force generated, the curtains can be opened and closed smoothly.

A) In the electric curtain opening / closing device according to the first aspect of the present invention, the geared cables 3 having both free ends as power transmission members are arranged in parallel on one side of the curtain rail 1. Two or more drive motors 2 and 2 are engaged with two or more drive gears 4 and 4, respectively, which rotate (see FIG. 1).

Therefore, the geared cable 3 has a strong pulling force on one side of the rail 1 by the drive gears 8, 8 which are respectively rotated by two or more drive motors 2, 2 before being inverted. On the side of the return that has been received and is inverted by the inversion guide portion 12 on this side, a strong pressing force is applied by the drive gears 8, 8 that are respectively rotated by the same two or more drive motors 2, 2. Will work.

Referring to FIG. 1 for example, when opening the curtains 9 that are closed, the geared cable 3 at the lower stage of the curtain rail 1 moves to the left in FIG. On the return side reversed by the section 12, the upper stage of the rail 1 moves to the right. When the geared cable 3 moves to the left in the lower stage of the rail 1, each drive gear 4 is rotated by two drive motors 2 and 2 arranged side by side on one side of the rail 1. , 4 is moving due to the strong pulling force. Further, when moving the upper stage of the rail 1 to the right on the return side which is reversed by the reversing guide section 12, it is moved by receiving the strong pressing force by the same two driving gears 4 and 4 as described above. There is. This also applies to the case where the geared cable 3 moves in the opposite direction when the curtains 9 are closed.

That is, when the free end geared cable 3 moves while revolving at one end of the curtain rail 1, no matter which direction it moves, two or more driving cables are used. The drive gears 4 and 4 rotated by the drive motors 2 and 2 simultaneously receive a strong pulling force and a pressing force to move. Therefore, the geared cable 3 as a whole obtains an extremely large driving force, and the curtains can be smoothly opened and closed regardless of the moving direction of the geared cable 3 even if the friction resistance is great due to a long rail or a curved rail.

B) In the electric curtain opening / closing device according to the second aspect of the present invention, the geared cable 3 of the power transmission member is made endless, and two or more identical curtain rails 1 are provided side by side. Two or more drive gears 4, 4 that rotate with drive motors 2, 2 of each type are engaged (see FIG. 2). The endless geared cable 3 is also reversible at the reversing guide portion 13 provided at the other end of the rail 1 so that the endless geared cable 3 can be circulated and moved in the cable passage holes at the upper and lower stages of the rail 1.

Therefore, in the geared cable 3, as in the first invention, each side of the rail 1 is provided with one or more drive motors 2 and 2 for rotation before being inverted. On the return side, which receives a strong pulling force by the gears 4 and 4 and is reversed by the reversing guide portion 12 on that side, each driving gear that is rotated by the same two or more driving motors 2 and 2 described above. A strong pressing force is also exerted by 4 and 4.

Since the geared cable 5 is endless, it is reversed by the reversing guide portion 12 on one side of the rail 1 and is circulatingly moved. Therefore, when the above-mentioned pulling force is applied, Although it is indirect, the pressing force by the driving motor 2 and the driving gear 4 on the other side of the rail 1 is also acting, and when the pressing force is applied, it is indirect but also the pulling force. It is working.

Therefore, the geared cable 3 also obtains an extremely large driving force as a whole, and the curtains are always opened and closed regardless of the moving direction of the geared cable 3 and even when the friction resistance is large due to a long rail or a curved rail. It can be done with a large driving force.

C) In the electric curtain opening / closing device according to the third aspect of the present invention, the drive motor is provided in which the geared cable 3 of the power transmission member is made endless and one or more units are provided on both sides of the curtain rail 1. The drive gears 4 and 4 rotating by 2 and 2 are meshed with each other (see FIG. 3). The endless geared cable 3 is also reversible by the reversing guide portion 13 provided at the other end of the rail 1 so that it can be circulated and moved in the cable passage holes of the upper and lower stages of the rail 1.

Therefore, before the geared cable 3 is inverted at one side of the rail 1, the drive cable 4 rotated by the drive motor 2 on that side receives a strong pulling force and the guide portion for inversion is provided. On the return side, which is reversed by 12, the strong pressing force by the drive gear 4 rotated by the same drive motor 2 is also received. At the same time, before the geared cable 3 is reversed on the other side of the rail 1, the geared cable 3 receives a strong pulling force by the drive gear 4 rotating by the drive motor 2 on that side, and the guide part for reversing on that side. On the return side, which is reversed at 13, the drive gear 4 rotated by the same drive motor 2 also receives a strong pressing force.

Therefore, when the pulling force and the pressing force are applied to the geared cable 3 by the driving motor 2 and the driving gear 4 on one side of the rail 1, at the same time, the driving motor 2 on the other side is driven. And the driving gear 4 exerts a pressing force and a pulling force, and even when the driving motor 2 and the driving gear 4 apply the pulling force and the pushing force on the other side of the rail 1, A pressing force and a pulling force are applied by the drive motor 2 and the drive gear 4 on one side of the rail 1. The pulling force and the pressing force increase with the distance from the drive motor 2 and the drive gear 4 on one side, and the force by the drive motor 2 and the drive gear 4 on the other side increases. .

That is, the pulling force and the pressing force by the drive motors 2 and 2 and the drive gears 4 and 4 on both sides of the rail 1 act on the geared cable 1 in a synergistic manner. Since a very large driving force is obtained as a whole, the geared cables 3 always open and close the cartons 9 with a strong and almost equal driving force regardless of the position of the rail 1.

D) In the electric curtain type opening / closing device according to the fourth aspect of the present invention, one or more driving motors 2 and 2 are provided on both sides of the curtain rail 1 and are rotated by the respective motors 2 and 2. The endless wire 5 of the power transmission strip is wound around the drive pulleys 6 and 6 (see FIG. 4). Therefore, the wire 5 is pulled by the drive pulley 6 which is rotated by the drive motor 2 on one side of the rail 1, and then immediately rotated by the drive motor 2 on the other side of the rail 1 when it comes to the return side. The pulling force of the drive pulley 6 is received.

Therefore, the wire 3 is always subjected to the pulling force by the drive pulleys 6 and 6 of the drive motors 2 and 2 on either side regardless of the moving direction thereof. Further, as the distance from the driving pulley 6 on one side of the rail 1 increases, the pulling force of the driving pulley 6 of the driving motor 2 on the other side strongly receives, so that the wire 5 always has a strong driving force. The curtains 9 are opened and closed with.

E) In the electric curtain opening / closing device according to the fifth aspect of the present invention, the endless timing belt 7 of the power transmission member is provided for driving two or more units arranged in parallel on one side of the curtain rail 1. It is meshed with two or more drive toothed pulleys 8, 8 rotated by motors 2, 2. Therefore, the timing belt 7 receives a strong pulling force by the two or more drive gears 8, 8 rotated by the two or more drive motors 2, 2 on one side of the rail 1.

Therefore, the timing belt 4 also opens and closes the curtains 9 with a strong driving force by the strong pulling force of the two driving toothed pulleys 7, 7 regardless of the moving direction thereof.

F) In the electric curtain type opening / closing device according to the sixth aspect of the present invention, each driving toothed pulley 8, which is rotated by one or more driving motors 2, 2 on each side of the curtain rail 1, An endless timing belt 7, which is a power transmission member, is wound around 8. Therefore, as in the case of the fourth wire, the timing belt 7 is pulled by the drive toothed pulley 8 rotating by the drive motor 2 on one side of the rail 1 and then inverted to the return side. When it comes, it immediately receives the pulling force by the driving toothed pulley 8 rotated by the driving motor 2 on the other side of the rail 1.

Therefore, the timing belt 7 is always subjected to the pulling force by the driving toothed pulleys 8 and 8 on either side regardless of the moving direction thereof, and also from the driving toothed pulley 8 on one side. As they are separated, they are subjected to a strong pulling force by the driving toothed pulley 8 on the other side. The timing belt 7 also always opens and closes the curtains 9 with a strong driving force.

[Effect of device]

 As is apparent from the above, according to the electric curtain opening / closing device of the present invention, the driving performance is dramatically improved by effectively using a plurality of drive motors of the same type. A large driving force can always be obtained without increasing the size, and even if the rail is long or curved, it is possible to smoothly open and close the caten regardless of the moving direction of the power transmission strip. .

That is, in the conventional electric curtain opening / closing device, the wires of the power transmission material, the timing belt, the geared cable, etc. are pulled by the drive pulley, the drive toothed pulley, the drive gear, etc., respectively. A large driving force was obtained, but when it was reversed and came to the return side, almost no driving force was generated or it was significantly reduced. On the other hand, in long Karten rails and curved rails, a very large frictional resistance is added to the moving power transmission strip. For this reason, especially with long curtain rails and curved rails, the driving force of the power transmission strip was significantly reduced, and the curtains could not be opened and closed without increasing the size of the drive motor.

On the other hand, in the electric curtain opening / closing apparatus according to the present invention, one or more drive motors and drive gears are provided on both sides of the rail, or two rails are provided on one side of the rail. By arranging more than one drive motor and drive gears in parallel, the overall drive force given to the geared cable of the power transmission material is increased by simply increasing the number of drive motors. Rather, they are able to increase synergistically.

Therefore, in the electric curtain opening / closing device according to the present invention, the power transmission member always has a strong driving force regardless of the moving direction thereof, regardless of whether the rail is long or curved. , You can always open and close the curtains with a strong driving force.

Further, since it is only necessary to use two or more drive motors as standard products of the same type, unlike the conventional case, the drive motors do not need to be upsized and rails and runners for them are not required. The curtain opening / closing device does not become large and heavy, and it is possible to reduce costs and has an excellent appearance.
