Description

[Detailed description of the invention] Industrial application field This invention is a rotating window in which the shoji rotates around a support shaft, such as a vertical axis rotating window, a horizontal axis rotating window, or a casement window, in which the opening angle of the shoji is kept constant. This invention relates to a device for fixing an arm stopper to a window frame.

Prior Art As shown in Japanese Utility Model Publication No. 58-47190, when the window is opened, an arm stopper is bridged between the window frame of the revolving window and the shoji to keep the opening angle of the shoji constant. An arm stopper fixing device is known that can disconnect the arm stopper from the window frame when the shoji must be turned over, such as when cleaning the back side of the shoji.

In this fixing device, a connecting shaft having a large-diameter shaft portion and a small-diameter shaft portion is provided on a support member so as to be movable up and down, and is biased downward by a spring, and a notch formed at one end of an arm stopper is used. The notch is dimensioned so that the small-diameter shaft portion of the connection shaft can be inserted therethrough, but not through which the large-diameter shaft portion can pass.

Problems to be Solved by the Invention With such a fixing device, it is difficult to connect and release the arm stopper and the connecting shaft.

In other words, first, to connect and release the connection, pull up the connection shaft with one hand against the spring force, hold the arm stopper with the other hand, and insert the notch into the small diameter shaft. , the arm stopper and the connecting shaft must be detached and connected or disconnected, and the operation becomes troublesome as both hands are used, and the arm stopper cannot be held down by hand without being able to hold the shoji. This is extremely dangerous as the shoji is supported by the shoji, and when the shoji is stirred up by strong winds, it may not be able to support itself and rotate.

Secondly, in order to connect the arm stopper and the connecting shaft, the small diameter shaft of the connecting shaft should face the fitting hole from the notch of the arm stopper, and the large diameter shaft and the fitting hole should be connected. It is necessary to match them accurately, but even at this time, the operation becomes extremely troublesome because the shoji must be rotated while lifting the connecting shaft with one hand and pulling the arm stopper with the other hand.

Means and action for solving the problem The device has a fixed block fixed to the window frame, a movable block slidable along the guide part of the window frame, and a small diameter part and a large diameter part fixed to the arm stopper. Consisting of a connecting shaft, the small diameter part inserted into the bay formed on the fixed block is held by the protrusion of the movable block, and the large diameter part is latched to the stepped part formed opposite the fixed/movable block, making it movable. The block is provided with a locking body that faces the notch formed in the guide portion and is movable up and down and biased upward, and when the movable block is placed in a position to clamp the aforementioned small diameter portion, the locking body faces the notch. By locking the arm stopper and moving the arm stopper with one hand or moving the movable block, the arm stopper can be connected and disconnected from the window frame, allowing connection and release operations. At times, the shoji can be supported with the other hand, and can be easily connected and disconnected.
