  The curtain opening and closing device according to the present invention is a device that automatically opens and closes a curtain using a magnet screw, and slides on the rotating shaft by rotating the rotating shaft around which the magnet body is spirally wound forward and backward. The curtain is opened and closed via a slider that can be moved freely. For this purpose, the magnet body can be spirally wound around one rotating shaft in one direction to open and close one curtain, or two curtains can be attached to the two left and right rotating shafts, respectively. It can be opened and closed. In addition, a magnet body can be spirally wound on both sides of a single rotating shaft in the right-handed screw direction and the left-handed screw direction, respectively, and a pair of left and right curtains can be simultaneously slid and moved to open and close.

  A curtain opening / closing device that opens and closes a pair of left and right curtains will be described with reference to FIG. A curtain opening / closing device 1 shown in the figure is a device that opens and closes a pair of left and right curtains 3, and includes two curtains 3 </ b> A and 3 </ b> B on a curtain rail 2. Each curtain is fitted with a curtain hook engaged with a curtain runner 8 slidably provided on the curtain rail 2.

  Reference numeral 4 denotes a rotating shaft in which a magnetic body of S poles and N poles is spirally wound at a predetermined pitch on the surface thereof, and is rotationally driven via a driving device 5 provided at one end. Further, in order to open and close the curtain at a desired speed, the rotational speed of the drive motor 51 can be reduced to a predetermined speed via the deceleration coupling 52. A slider 10 (10A, 10B) is slidably mounted on the rotating shaft 4, and a magnet body facing the spiral magnet body of the rotating shaft 4 is placed on the sliding surface of the slider 10 at the same pitch. A sliding portion wound in a spiral shape is provided.

  Further, a right magnet shaft 4A in which a magnet body is provided in a spiral shape in the right-hand screw direction is provided on one side from the center of the rotating shaft 4, and a left magnet in which a magnet body is provided in a spiral shape in the left-hand screw direction on the other side. A shaft 4B is provided. Further, a magnet body is wound around the sliding portion of the slider 10A that slides on the right magnet shaft 4A portion in the same right screw direction as the right magnet shaft 4A, and the slider of the slider 10B that slides on the left magnet shaft 4B portion. A magnet body is wound around the moving part in the same left screw direction as the left magnet shaft 4B. A predetermined gap is provided between the outer diameter of the rotating shaft 4 and the sliding portion of the slider 10. Thus, by making the inner diameter of the sliding portion of each slider 10 larger than the outer diameter of the rotating shaft 4, the slider 10 can slide in a non-contact state.

  For this purpose, the curtain runner 8A is connected to the slider 10A, the curtain runner 8B is connected to the slider 10B, the curtain runner on the moving tip side of the pair of left and right curtains is connected to each slider, and the rotating shaft 4 is rotated forward. Rotate in the direction and simultaneously move in the direction to close the pair of left and right curtains to close the curtain, rotate the rotating shaft 4 in the reverse direction and simultaneously move in the direction to open the pair of left and right curtains and open the curtain The pair of left and right curtains 3A and 3B can be integrally opened and closed.

  As shown in FIG. 2A, the slider 10 has a round hole formed at the center of the sliding block 11, and a sliding portion 12 having a magnet body spirally disposed on the surface of the round hole. Provided. As the sliding block 11, for example, a non-magnetic stainless steel block or resin block having a cylindrical shape or a prismatic shape (shown by an imaginary line) shown by a solid line in the drawing can be used. Further, a cover plate 13 made of a sheet metal that covers the block is attached to the sliding block 11, and the lower end portion of the cover plate 13 is connected to the curtain runner 8 via a connecting rod 14.

  The curtain runner 8 includes a runner portion 8A that slides in the curtain rail 2, a leg portion 8B that hangs down from the runner portion 8A, and a curtain hook mounting portion 8C that is provided below the leg portion 8B. I have. Therefore, when the connecting rod 14 is fixed to the leg portion 8B and the curtain runner 8 and the cover plate 13 are connected, the sliding block 11 to which the cover plate 13 is attached is prevented from rotating but can slide. Become. Therefore, when the rotating shaft 4 rotates, the sliding block 11 slides and moves following the magnetic field that changes due to the rotation of the magnet body spirally disposed on the surface of the rotating shaft 4.

  Further, as shown in FIG. 2B, washers 15 are attached to the front and rear ends on both sides of the sliding block 11 having a length L. This is because the inner diameters of the washer members 15, 15 arranged at intervals of the length L are made smaller than the inner diameter of the sliding block 11, the washer members 15, 15 on both sides are brought into contact with the rotating shaft 4, and the rotating shaft 4 This is to prevent the magnet bodies from being magnetically attached to each other by preventing direct contact with the sliding block 11.

  Therefore, as shown in FIG. 3, even if the inner diameter D of the sliding block 11 is set to be slightly larger than the outer diameter d of the rotary shaft 4, the washer member 15 having an inner diameter slightly larger than the outer diameter d and smaller than the inner diameter D is provided. Contact the rotating shaft 4. That is, a predetermined gap is provided between the exterior part 41 around which the magnet body of the rotating shaft 4 is wound and the sliding part 12 around which the magnet body of the slider 10 is wound. With this configuration, the washer member 15 is made thin and the hole is made to be a slippery sliding surface, so that the washer member 15 and the rotating shaft 4 are easily slidable, so that the rotating shaft 4 and the slider are in contact with each other. Since a predetermined gap is formed between the magnetic bodies and the magnet bodies are not magnetically attached to each other, the sliding movement of the slider 10 can be lightened.

  The magnet body spirally wound around the surface of the rotating shaft 4 is preferably a magnet body that is flexible enough to be wound around a bar and has a strong magnetic force. Therefore, in this embodiment, the sheet-like magnet body which mix | blended the neodymium magnetic body with the rubber material is used. Moreover, it is set as the spiral shape by which S pole and N pole are alternately arrange | positioned by predetermined pitch (for example, 1 mm pitch).

  The sliding part of the sliding block 11 which becomes the sliding surface of the slider 10 is also formed by winding a sheet-like magnet body containing a similar neodymium magnetic body in a spiral manner with the same pitch and the south pole and the north pole alternately. Yes. The rotating shaft 4 and the slider 10 constitute a magnet screw, the curtain runner 8 attached to the curtain rail 2 is connected to the slider 10, and the rotating shaft 4 is rotated forward and backward to open and close the curtain. is there.

  The magnetic force (magnetic flux density) of the magnet body is preferably about 1000 to 1500 gauss (0.1 to 0.15 Tesla), and a sheet-like magnet body in which a neodymium magnetic body is blended with the rubber material described above. A magnet body using a neodymium magnetic body that exhibits such a high magnetic flux density is preferable because it can easily achieve a desired magnetic force of 1000 gauss or more.

  In the present embodiment, a sheet-like magnet body having a magnetic force of 1400 gauss (0.14 Tesla) with a thickness of 1 mm is spirally wound around a bar having a diameter of 6 mm to form a rotating shaft 4 having an outer diameter of 8 mm. 4 and the slider 10 has a predetermined gap of about 0.5 mm on one side, and the slider 10 having the above-described length L of about 60 mm is assembled. Further, with this configuration, it has been confirmed that the slider 10 can be easily and reliably slidable following the rotation of the rotating shaft 4.

  This is because when the rotating shaft 4 rotates, the S and N poles alternately arranged at a predetermined pitch move, so that the S (N) pole on the rotating shaft 4 side and the N (S) pole on the slider 10 side attract each other. This is probably because the S (N) pole on the rotating shaft 4 side and the S (N) pole on the slider 10 side repel each other and the slider 10 slides smoothly.

  Since it is configured as described above, the slider 10 can be slid and moved lightly using the attractive force and repulsive force between the magnetic bodies, and the slider 10 can be slid simply by rotating the rotating shaft 4 lightly. It becomes the composition to do. Therefore, a small drive motor 51 with a small capacity can be used.

  Further, the sliding movement of the slider 10 can be stopped using a stop member. For this purpose, a stop member that abuts against the end of the slider 10 or the washer members 15 attached to both sides of the slider 10 can be provided at the center and both ends of the rotating shaft 4 to define the stop position of the slider 10. For example, as shown in FIG. 1, support blocks 7A and 7B that rotatably support both sides of the rotating shaft 4 and a support block 7C that rotatably supports the central portion of the rotating shaft 4 are used as stop members. Can do.

  With the above configuration, even if the slider 10 is stopped via the stop member, the rotary shaft 4 and the slider 4 are merely attracted to each other by magnetic force. Therefore, even if the rotary shaft 4 continues to rotate, the slider 10 runs idle and does not deviate from its stop position. Therefore, the curtain can be stopped at a predetermined opening / closing position where the stop member is installed.

  As the stop member, a member other than the support block may be used as long as the member is in contact with the end of the slider 10 or the washer member 15 attached to both sides of the slider 10. At this time, it is preferable that the installation position of each stop member can be changed. If the installation position of the stop member provided at both ends can be changed, the open attitude of the curtain can be easily changed according to preference, and if the installation position of the stop member provided at the center can be changed, It is preferable because the attitude of the curtain closed can be changed.

  Also, the sliding movement of the slider 10 can be stopped by providing a nonmagnetic portion instead of the stop member. In this case, if a nonmagnetic part is provided in the center part and both ends of the rotating shaft 4, this nonmagnetic part becomes a stop position where the slider 10 idles, and the opening / closing position of the curtain can be defined. Even if the rotary shaft 4 rotates and the slider 10 is idle, the magnetic bodies of the rotary shaft 4 and the slider 10 are not magnetically attached. Does not occur.

  The drive device 5 includes a drive motor 51 that rotates the rotating shaft 4 forward and backward. The drive motor 51 in this case is preferably a brushless motor capable of forward and reverse rotation. If it is this structure, it will become a motor with a low noise and a long life, and low-speed rotation is also possible via the deceleration coupling 52, and opening and closing operation of a curtain can be performed quietly. Further, since the curtain can be easily opened and closed by simply rotating the rotating shaft 4, the curtain can be automatically opened and closed quietly by using the drive motor 51 having a small driving force.

  In addition, since the position of the slider 10 is fixed by the attractive force between the magnetic bodies, the slider 10 can be gripped and slid by being pulled more strongly than the attractive force. Also, when the drive motor 51 is driven with the two left and right curtains 3A and 3B mounted and the position of one of the curtains changed, the curtains 3A and 3B slide in predetermined directions, respectively, and reach the respective stop positions. And stop. At this time, the curtain that has reached the stop position earlier is in a state in which the slider 10 included in the curtain is idle at the stop position. Therefore, the phase of the pair of left and right curtains 3A and 3B can be matched by continuing to drive the drive motor 31 until the other curtain reaches the stop position.

  As described above, once the left and right curtains 3A and 3B are once fully closed or fully opened regardless of the initial arrangement position of the slider 10, each slider 10 is set to a predetermined corresponding position. Thereafter, the pair of left and right curtains 3A and 3B are opened and closed simultaneously in accordance with the forward and reverse rotations of the drive motor 51.

  Therefore, when the curtain is removed and replaced after washing, it is not necessary to consider the position where the curtain is to be attached, and the curtain hook is simply fitted into the curtain hook attachment hole 8C. The operation can be performed and the curtain can be easily replaced.

  Further, the drive device 5 can be provided with the communication function means 53 so that the curtain 3 (3A, 3B) is automatically opened and closed by remote control. For example, by making control possible via infrared communication, the curtain can be opened and closed automatically by remote operation, not only for people who are indoors, but also for people who are outdoors, using mobile phones and control devices that can communicate with infrared rays. Can do.

  As described above, according to the present invention, a rotating shaft in which a magnetic body of S and N poles is spirally wound at a predetermined pitch on the surface, and a similar magnetic body is spirally formed on the inner sliding surface. A magnet screw is composed of a slider having a wound sliding part, a curtain runner is connected to this slider, and the rotating shaft is rotated forward and backward to open and close the curtain so that the sliding part is not contacted. A curtain opening and closing device that can be slid in a state and that can be gently and lightly opened and closed without generating abrasion powder or abnormal noise can be obtained.

  Further, one side from the central part of the rotation shaft is a right magnet shaft provided with a magnet body in a spiral shape in a right-hand screw direction, and the other side from the central part is a left-hand side provided in a spiral shape in a left-hand screw direction. If the magnet shaft is provided with a pair of left and right sliders wound in a spiral shape corresponding to each screw direction, the rotating shaft is rotated forward and backward to open and close the pair of left and right curtains gently and lightly simultaneously. be able to.

  Therefore, the present invention can be suitably used as a curtain opening / closing device that can be automatically opened and closed quietly and lightly.
