The detachment prevention device C is shown in FIGS. 4, 5, and 6.
As shown in the figure, the shoji shoji slip-off preventing mechanism includes a rod 20, a base 21, a member for preventing the shoji from coming off, such as a stopper 22, an operating pin 23, a leaf spring 24, a locking body 25, and the like.

The base 21 is integrally provided with mounting horizontal plates 31, 31 bent in a substantially crank shape on both longitudinal end faces 30a, 30a of a vertical plate 30, and a long hole 32 in the longitudinal direction is formed in the vertical plate 30. At the same time, a stopper piece 33 is stamped and formed, and a pair of mounting horizontal plates 3 are attached so that the vertical plate 30 faces a notch 34 formed near the left vertical stile 12 in the outdoor wall 10b of the upper stile 10.
1 and 31 are screws 35 and 3 on the indoor surface of the outdoor wall 10b.
It is fixed at 5.

The base 21 is also fixed to the upper stile 10 near the right stile 13.

The rod rod 20 is a long plate-like body, and is attached to the upper frame 1.
A pair of horizontal mounting plates 31, 3 of the base 21 are located in the upward groove 10' of the base 21 so as to be movable in the longitudinal direction.
A pair of elongated holes 36, 36 are formed in the longitudinal direction in a portion facing the elongated holes 36, and pins 37 inserted through the elongated holes 36 are fixed to the mounting horizontal plate 31, respectively, and one longitudinal end 20a is A through hole 38 facing the notch grooves 19, 19 of the left vertical stile 12 and serving as a locking portion is formed.

The operating pin 23 is fixed to the rod 20 and is slidably fitted into the elongated hole 32 of the vertical plate 30.

The stopper 22 is attached to the vertical plate 30 with a pin 39 so as to be movable up and down, and has one side 22a in contact with the operation pin 23, the other side 22b projecting upward from the vertical plate 30, and a locking piece 33 in contact with the stopper 22. A stop protrusion 22c and a protrusion 22 protruding from one side 22a
d, is rotatable around the pin 39 between a retaining position protruding upward from the vertical plate 30 and a non-receiving position at the same height as the vertical plate 30, and is rotatable by the base 21. It constitutes a mechanism to prevent it from coming off.

The leaf spring 24 is fixed to the outdoor wall 12b of the left vertical stile 12 with screws 40, and a cylindrical locking body 25 is provided at its free end.
is fitted into the hole 41 of the outdoor side 12b, and is pressed against the rod rod 20 by the spring force (elastic force) of the leaf spring 24.

A door stop member 42 is attached to the connecting wall 3c of the left vertical frame 3.
is fixed oppositely to the rod 20 with screws 43.

However, when installing shoji B on window frame A, the fourth
As shown in Figures 5 and 6, the rod 20
One end 20a is inserted into the vertical stile outer wall 12d from the notch groove 19.
It should be in a position that protrudes outward. This position is determined by one pin 37 coming into contact with the end of one elongated hole 36.

As a result, the stopper 22 is in the non-removal preventing position and is housed in the vertical plate 30 of the base 21, and the locking protrusion 22c is facing downward and the operation pin 2
The position is opposite to 3.

In this state, shoji B is built into window frame A in a Kendon style. At this time, the stopper 22 is in the non-removal preventing position, so it does not interfere with the erection.

After this, when the shoji B is closed and the rod rod 20 is brought into contact with the door stop member 42, the results shown in FIGS. 8, 9, and 10.
As shown in the figure, the rod rod 20 is pushed to the right with respect to the upper frame 10, and the operating pin 23 is moved to the stopper 22.
The stopper 22 is rotated counterclockwise around the pin 39, and the stopper 22 reaches a position where it protrudes upward from the vertical plate 30 of the base 21, and the locking protrusion 22c is rotated counterclockwise. The stopper 22 is held in a position where the stopper 22 is retained by the stopper piece 33.

At the same time, the locking body 25 fits into the through hole 38 of the rod 20 and locks the rod 20 so that it does not move in the longitudinal direction.

Because of this, the distance between the stopper 22 and the connecting wall 1c of the upper frame 1 is narrowed, and the upward movement of the shoji B is restricted, so the shoji B will not come off even if strong winds or the like act. .

Therefore, when the shoji B is closed after it has been erected within the window frame A, the locking mechanism is automatically activated, and it is safe to avoid forgetting to perform the locking operation.

Further, since the rod rod 20 is locked from moving in the longitudinal direction by the locking body 25 and the through hole 38, the rod rod 20 may be prevented from moving in the longitudinal direction by a collision with the frame that occurs when the shoji B is opened or closed, or by other external forces. Since the stopper 22 is not moved in the longitudinal direction and the stopper 22 is not rotated to the non-removal locking position by the operation pin 23, the locking function is not released unexpectedly.

Further, since the locking body 25 automatically fits into the through hole 38 of the rod rod 20 and locks, there is no need to perform a special locking operation, and there is no need to forget the locking operation.

Further, in order to unlock the rod rod 20, as shown in FIG. 8, a screwdriver is inserted through the notch rod 19, the locking body 25 is pushed and removed from the through hole 38, and the rod rod 20 is pulled out.

Then, when the rod rod 20 is pulled out, the operating pin 23 comes into contact with the projection 22d of the stopper 22 and rotates the stopper 22 clockwise to the non-removal position, so that the shoji B can be removed from the window frame A.

As shown in FIG. 11, the locking body 25 has a larger diameter than the through hole 38, has a tapered tip 25a, and has a tapered tip 25a.
5a may be fitted into the through hole 38.

Furthermore, a notched recess may be provided instead of the through hole 38, and the locking body 25 may be engaged with the notched recess.
In other words, it is sufficient to form a locking recess in the rod rod 20 that engages with the locking body 25, and in this case, the plate spring 2
4 with a screwdriver or the like to release the locking body 25 from the locking portion.

Further, instead of the base 21 and the stopper 22, a mechanism for preventing the device from coming off may be provided as shown in Japanese Utility Model Application No. 58-89562.

Effects of the invention When the shoji is closed after the shoji is placed in the window frame, the rod rods 20 move to the storage position and the shoji removal prevention member becomes the removal prevention position, automatically performing the removal prevention function, and the rod rods Since the locking body 25 engages with the locking recess 20 and the rod rod 20 is locked at the storage position and cannot be moved, the rod rod 20 may be damaged by collision with the frame or other external force when the shoji is opened or closed. to prevent the shoji removal prevention member from moving to a non-removal prevention position and the removal prevention function from being unexpectedly released.

Furthermore, since the locking body 25 is pressed and held against the rod rod 20 by an elastic body, the rod rod 20 slides against the locking body 25, and when the rod rod 20 is in the storage position, the locking body is locked. Since it automatically engages with the recess, there is no need to specially operate the locking body 25, which not only eliminates the need for troublesome operations, but also ensures that the rod rod 20 is locked without forgetting to lock it. .
