The following problems remain in the conventional technology.
If a curtain is provided inside the glass door or the glass window, that is, indoors, heat is blocked by the curtain and heat is trapped between the glass plate and the curtain. For this reason, in recent years, it has been desired to attach a curtain to the outside of the glass door or the glass window, that is, the outdoor side. However, in the case of an external curtain with a curtain attached to the outside of a glass door or glass window, electric power is supplied to the curtain drive mechanism provided on the outdoor side when the curtain is opened and closed electrically. There is a disadvantage that wiring work is required to open the indoor power line and connect it to the drive mechanism.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide an external curtain opening / closing device that does not require wiring work for opening a through hole for passing a power line through a wall or the like.

  The present invention employs the following configuration in order to solve the above problems. That is, the external curtain opening and closing device of the present invention is an external curtain opening and closing device that is attached to the outside of a glass door or a glass window and can open and close a curtain that covers a glass plate, and is on the outside of the glass door or glass window. A winding drive mechanism that can wind up and store the curtain, and a power supply mechanism that supplies power to the winding drive mechanism, and the power supply mechanism is disposed inside the glass plate. An inner power transmission coil that generates an alternating magnetic field, and an outer power receiving unit that is disposed outside the glass plate and that is connected to the winding drive mechanism and generates electric power generated by electromagnetic induction by the alternating magnetic field to the winding drive mechanism. And a coil.

  In this external curtain opening and closing device, the power supply mechanism is provided with an inner power transmission coil and an outer power reception coil that are separately disposed on the inner side and the outer side with a glass plate interposed therebetween and transmit power by electromagnetic induction. By transmitting power to the outdoor take-up drive mechanism without contact, it is possible to open and close the curtain by driving the outer take-up drive mechanism without the need for wiring work such as opening a through hole in the wall. it can. In addition, since an alternating magnetic field is generated through the glass plate, good electric power transmission is possible without being shielded by a metal plate or the like.

  In the external curtain opening and closing device of the present invention, the winding drive mechanism includes a storage portion that can store and retract the curtain that can be taken in and out of the opening, and is provided at the tip of the curtain.
