[Invention sword effect]

According to this invention, by providing a locking mechanism, it is fixed integrally in normal times and serves the purpose of crime prevention, but by releasing the lock, a part of the surface lattice can be removed, and in an emergency. Escape becomes possible. Additionally, if a portion of the grid is removed, it will be convenient for taking items in and out of the window, cleaning the window glass, and other benefits.

Further, this locking mechanism is protected by a switching cover 11i, and has a structure that prevents the locking mechanism from being released from outside.

For this reason, a part of the surface grid cannot be removed by someone else from the outside during normal times, and it is safe from the viewpoint of crime prevention.

Furthermore, in the first embodiment shown in Figures 1 to 4, the locking mechanism is tightened by screws, so the structure is simple.

Further, according to Examples 2 and 4, the locking mechanism is of a sliding type, so that the operation is easy. Furthermore, since the fitting frame is removed inward, there is no need to worry about creating a seam on the outside, and the appearance is good.

Since the locking mechanism of the fifth embodiment is a set of levers, it is similarly easy to operate.0 Note that the locking mechanism is not limited to the above-mentioned embodiment, and may be any other mechanism. Also, any protective cover that surrounds the locking mechanism is fine.

On the other hand, according to the third embodiment, since the protective cover is covered with a cap, it becomes impossible to insert hands, tools, etc. into the protective cover from the outside, and safety is improved. In particular, since the cap is inside the protective cup (-), it is difficult to remove the cap from the outside, and even if you try to remove it,
The gap between the cap and the window is narrow, so it gets stuck in the middle and you can't remove the cap, making it safer. To remove the cap from indoors, you can easily open the window by placing your hand over the drawer hole and pulling it out.

Although the cap shown in Example 5 has a structure that can be opened from the outside, the gap between the cap and the window is narrow, so it can only be opened halfway, and furthermore, the side plate protects the cover and narrows the opening. , hands, tools, etc. cannot be inserted into the protective cover from the outside. Therefore, the crime prevention effect is improved.

Note that the cap shown in Examples 4 and 5 has a structure that simply covers the protective cover, but the cap may have a function of fixing a locking mechanism. For example, part of the side surface of the cap of Example 4 may be made to protrude inward, or a protruding member may be provided.

The structure may be such that it is in contact with the insertion member and prevents the insertion member from moving. Further, a plate material is provided between the side plates of the cap of Example 5.

It is also possible to hold the bent bolt in a bent state.
