Description

[Detailed description of the invention] (Field of industrial application) This invention is a sash attachment/removal aid used when removing or attaching a shoji from a window frame in a horizontal or vertical rotating window installed in a building. In particular, it relates to a sash attachment/detaching aid suitable for attaching/detaching a rotating window shoji of a type in which the shoji is rotated approximately 180 degrees, the shoji rotating shaft is removed from the bearing, and the entire shoji is removed from the window frame.

(Prior Art) Generally, when a revolving window is newly installed in a building, a shoji screen is attached to the window frame in advance at a factory, and then this is attached to the building using a machine such as a crane at the construction site. However, after the building is completed, there are cases where it is desired to remove the installed shoji from the window frame in order to repair or replace the attached parts of the shoji. In this case, if the shoji is lightweight, several workers can remove the rotating shaft while supporting the shoji, remove the shoji from the window frame, and reinstall it manually after repair. In the case of shoji with heavy glass or built-in blinds, the weight of the shoji is large (some weigh more than 100 kg), and it is extremely dangerous to remove and install it manually, even if it is done by a large number of people. It was hot.
