Description

  The present invention relates to a ventilation device and an opening device installed in a building, a house, and the like, and more particularly to a ventilation device and an opening device configured as a step window.

  In recent years, ventilation devices have been demanded as countermeasures against global warming, energy saving, and power saving, and for residential use, stepped windows having two upper and lower opening windows have been used (see Patent Document 1). In particular, as a ventilator with improved ventilation efficiency, a so-called upside down open window with the opening direction of the upper window and the lower window being reversed has been used. As an opening / closing operation means of such a ventilator, there are one that opens and closes a window by operating a rotary handle called an operator handle, and one that uses a latch handle.

  Among such ventilators, the conventional corrugated window type ventilator using an operator handle is provided with an operator handle for opening and closing the upper window on a seamless (intermediate frame) that partitions the upper window and the lower window. An operator handle for opening and closing the lower window is attached to the frame. Moreover, the conventional corrugated window type ventilator using a latch handle is configured by attaching a latch handle to the free ends of upper and lower shojis.
