Description

  The present invention relates to a shutter, and more particularly to an external electrical wiring structure of a retrofit type electric shutter installed with a base member attached to an outer wall of a building.

  As shutters, a base member is attached to the outer wall of a building having windows, and a shutter box that houses an electric winding part that winds and lowers shutter slats on the base member, and both sides of the shutter slats are guided up and down freely. There is a retrofit-type shutter mainly for remodeling, in which a shutter frame having a guide rail is attached. The base member is used when the outer wall is soft and the shutter is difficult to attach, for example, when the outer wall is a metal siding in which a urethane foam resin is filled in a metal outer shell.

  In particular, in the case of an electric shutter, when connecting the electric wiring connected to the electric part of the winding part to a power source, for example, connecting to an internal power source (indoor power outlet), a hole is made in the wall. It is necessary to draw the electric wiring indoors, and when connecting to an external power source (outdoor power outlet), it is necessary to open a hole in the shutter frame or the base member and pull out the electric wiring to the outdoors.

  As a related technique, a remodeling shutter using a base frame (see Patent Document 1) is known.
