[Composition of curtain opening and closing device]
First, the configuration of the curtain opening / closing device 1 according to the embodiment will be described.
The curtain opening / closing device 1 mainly includes a pair of runners 11, 11 that are driven in the curtain rail 51, and a driving roller that is positioned between the pair of runners 11, 11 and that drives and runs while pressing the lower surface of the curtain rail 51. 21 and a casing 41 suspended from the curtain rail 51 via a pair of runners 11, 11. Note that the type of curtain rail 51 to which the curtain opening / closing device 1 can be attached is a C-shaped rail or a square rail with an open bottom surface.

  The runner 11 is composed of a pair of wheels that are pivotally supported on the rotating shaft 12, and a horizontal rotating shaft 13 extends downward from the center of the rotating shaft 12. The wheel diameter of the runner 11 is smaller than the open width of the lower surface of the curtain rail 51. A coil spring 15 is connected to the lower end of the horizontal rotation shaft 13, and the lower end portion of the coil spring 15 is fixed to the housing 41. In addition, a disc-shaped rotation plate 14 is fixed to the position above the horizontal rotation shaft 13 and outside the housing 41 so as to be integrated with the horizontal rotation shaft 13. Note that the rotation plate 14 may be a rod-shaped rotation rod. In short, it is sufficient if the horizontal rotation shaft 13 can be manually rotated.

  The coil spring 15 is also twisted and twisted, and in the attached state, the runner 11 is biased downward and also horizontally, so that the rotary shaft 12 is biased in one direction. It is energized. Therefore, if the rotating plate 14 is manually rotated and the runner 11 is inserted into the curtain rail 51 from the open portion of the lower surface of the curtain rail 51 and then the hand is loosened, the rotating shaft 12 becomes longer than the length of the curtain rail 51. The runner 11 can travel in the curtain rail 51 by rotating in a direction orthogonal to the vertical direction and being fixed.

  The driving roller 21 is pivotally supported by the casing 41, and the upper half of the driving roller 21 protrudes outward from the casing 41. The driving roller 21 travels while pressing the lower surface of the curtain rail 51 at the protruding portion. This pressing force is applied as a reaction of the downward biasing force of the runner 11 by the coil spring 15. A plurality of grooves are formed in the outer peripheral surface where the driving roller 21 is in contact with the curtain rail 51 so as to be orthogonal to the rotation direction. Thereby, friction with the drive roller 21 and the curtain rail 51 becomes large, and the idling of the drive roller 21 can be prevented.

  The drive device includes a motor 23, a transmission gear 24 that transmits the rotation of the motor 23, and a drive gear 22 that replaces the rotation transmitted by the transmission gear 24 with the rotation of the drive roller 21. Further, the transmission gear 24 includes a worm gear 241 and a plurality of spur gears 242 fitted to the rotation shaft of the motor 23, and also plays a role of reducing the rotation of the motor 23. Then, the reduced rotation of the motor 23 is transmitted to the drive gear 22 so that the drive roller 21 integrated with the drive gear 22 is driven.

  In order to reduce the size of the curtain opening / closing device 1, a super capacitor is used as the capacitor 31 in the embodiment. The supercapacitor has a smaller storage capacity than a so-called storage battery, but it has a merit that it can be used semi-permanently while the storage battery has a short life of 500 to 1000 times. And the capacitor | condenser 31 is electrically connected with the solar panel 43 attached to the outer side of the container main body of the housing | casing 41, and the capacitor | condenser 31 and the motor 23 are also electrically connected. In addition, an electric circuit breaker 32 is electrically inserted between the capacitor 31 and the motor 23. In the embodiment, a pair of inclination sensors are used for the electric circuit breaker 32. Of course, a battery may be used in place of the capacitor, but in this case, periodic battery replacement is required.

  The inclination sensor detects the inclination of the casing 41 in the traveling direction, and the electric supply from the capacitor 31 to the motor 23 is turned off when a predetermined angle is exceeded. Referring to FIG. 2 as an example, when the upper part of the casing 41 is tilted to the right, the right electrical circuit breaker 32 is activated to turn off the power supply. The device 32 is activated to turn off the power supply, and the curtain opening / closing device 1 that is running automatically stops.

  When the curtain opening / closing device 1 pulls the curtain 52 and cannot move due to the end of the curtain rail 51 or any obstacle, the rotational torque of the motor 23 becomes maximum and the casing 41 is centered on the drive roller 21. Will tilt. The electric circuit breaker 32 using the inclination sensor according to the embodiment uses the inclination of the housing 41, but an electric load detection sensor is added to the electric circuit breaker 32 by using the maximum rotation torque of the motor 23. It can also be used.

  The casing 41 is a flat, substantially rectangular container having a small thickness, and is composed of a container body and a detachable front lid. FIGS. 2, 3 and 5 show a state where the front lid is removed. . And the lower part of the horizontal rotation axis | shaft 13 and the coil spring 15 following it are accommodated, and the lower end part of the coil spring 15 is being fixed to the container main body so that attachment or detachment is possible. The rotating shaft of the driving roller 21 including the driving gear 22 is pivotally supported by the container main body, and the lower half of the driving roller 21 is housed in the housing 41. Further, the motor 23, the transmission gear 24, the capacitor 31, and the electric circuit breaker 32 are accommodated in the casing 41. The rotation shaft of the transmission gear 24 is pivotally supported by the container body, and all the others are detachable. It is fixed to the container body as possible.

  And the housing | casing 41 which concerns on an Example is the magnitude | size about a cigarette box, each of the both sides | surfaces (front side and the back side of the running direction of the housing | casing 41) of the container main body located in the exterior of the housing | casing 41 Auxiliary runners 42, 42 are fixed to the upper part, and hook insertion rings 44, 44 through which the curtain hooks are inserted are fixed immediately below. The auxiliary runner 42 has substantially the same specifications as the runner 11, prevents excessive inclination of the casing 41 with respect to the traveling direction, and prevents the hook insertion ring 44 from entering the curtain rail 51 due to the inclination of the casing 41. In addition to playing a role, it also plays a role of facilitating manual travel when the curtain opening / closing device 1 is not energized.

[Use of curtain opening and closing device]
Next, a usage example of the curtain opening / closing device 1 will be described below.

  First, the curtain opening / closing device 1 is attached to the curtain rail 51 with the solar panel 43 attached side facing outward. The attachment method is as described in paragraph [0014]. After being attached to the curtain rail 51, the hook insertion rings 44, 44 are inserted into the hook insertion rings 44, 44 through the hook at the tip of the curtain 52 and the next hook respectively. This completes the installation of the curtain opening and closing device 1. In addition, since the rotating shaft 12 of the runner 11 is always urged so as to be orthogonal to the length direction of the curtain rail 51 after the curtain opening / closing device 1 is attached, the curtain opening / closing device 1 has the curtain rail 51. There will be no departure.

  Electricity of the solar panel 43 generated by daylighting is sent to the capacitor 31 and charged during the sunshine hours. Since the curtain 52 is opened and closed several times a day, the solar panel 43 and the capacitor 31 having a predetermined capacity are selected, so that electricity is not deficient even in long-term bad weather.

  By incorporating a remote control receiver in the curtain opening / closing device 1, remote control operation becomes possible. By turning on the travel switch of the curtain opening / closing device 1, the curtain opening / closing device 1 travels while pulling or pushing the curtain 52. For example, when the curtain opening / closing device 1 travels and the curtain 52 is stored in the curtain pool, the curtain 52 itself does not move, but the curtain opening / closing device 1 is rotated by the rotation of the driving roller 21. The upper part is inclined to the curtain pool side. For this reason, the electric circuit breaker 32 works to turn off the power supply, the curtain opening / closing device 1 automatically stops, and the travel switch of the curtain opening / closing device 1 is turned off.

  If the curtain opening / closing device 1 breaks down or the curtain opening / closing device 1 is not used, the runner 11 can be rotated horizontally by pulling the curtain 52 at the hook position inserted into the hook insertion rings 44, 44 downward. The shaft 13 is pulled downward, the driving roller 21 is separated from the curtain rail 51, and the curtain 52 can be manually opened and closed. Further, even if the curtain 52 is pulled while being pulled down, any one of the auxiliary runners 42 is driven while being in contact with the lower surface of the curtain rail 51, so that the manual opening and closing of the curtain is extremely easy. 5 shows a state in which the curtain 52 is pulled leftward. The left auxiliary runner 42 is in contact with the lower surface of the curtain rail 51, the right coil spring 15 is extended, and the drive roller 21 is attached to the curtain rail 51. The state is separated from the lower surface.
