Description of the Related Art As a conventional technique relating to a fixed window frame provided on a door, a wall or the like, Japanese Utility Model Publication No. 56-4789 discloses one frame member provided with a flange that contacts the front side of the door and the like. The other frame member with a flange that contacts the back side is inserted into each inner surface of the window hole along the thickness direction of the door, etc., and is provided on the male engaging portion provided on one frame member and the other frame member. by engaging the female engaging portions, Gala both frame member
It is described that the plate is sandwiched and fixed. Further, Japanese Utility Model Publication No. 44-29489 discloses a structure of a window frame in which three frame members are set as one set.

[0003]

Both of these publications attempt to hold the frame members together by utilizing the hooking engagement of the claws formed on the frame member.
Since it is to be fitted into the window hole along the thickness direction of the door or the like, when a force along the thickness direction of the door or the like acts on the frame material due to a large pressing force acting on the surface of the glass plate, for example,
There was a risk that the frame material would come off the window hole.

There is also a problem in that the anti-theft property is poor because the frame member can be easily removed by prying the flange with a driver or the like. In order to prevent this, the frame material must be fixed to the inner surface of the window hole with nails or screws, which causes another problem that the efficiency of the assembling work becomes poor.

The present invention aims to solve these problems.

[0006]

Window frame of the present invention, in order to solve the problem] has an outer frame member groups each two disposed between each inner peripheral surface and the outer peripheral surface of the glass plate of the window hole, the glass plate includes an inner frame member groups each two sandwiching the front and back sides, the two outer frame member includes a first outer frame member having a flange striking the surface of such a door or wall, strike the back surface of such doors and walls It consists a second outer frame member having a flange. And on both outer frame materials, inside the window hole

Each is provided .

On the other hand, in the inner frame material group, a glass plate is
First inner frame member provided with a glass pressing portion pressed from the side
And the glass holding part that holds the glass plate from the other side
A second inner frame member provided, and a first inner frame member
A first groove that fits into the pair of overlapping first protrusions
To form the first groove and the pair of the first ridges to form an outer frame.
The material is held irremovably and one inner frame material is a glass plate
Is a first engaging means that is held so that it cannot be separated.

Further, the second inner frame member, the first inner frame member and the first inner frame member
When the second inner frame member is moved toward at least one of the outer frame members toward the outer frame member along the wide surface of the glass plate, the second inner frame member is engaged with the second inner frame member and the second inner frame member is moved to the glass plate. A second engaging means is provided for holding the same so that it cannot be separated. And the first

The order of attaching the second inner frame member in a state of overlapping the glass plate to the first inner frame member, it is possible to attach the glass plate window hole.

Since each outer frame member is held irremovably in the thickness direction of the door or the like by the inner frame member moved from the direction along the wide surface of the glass plate, the inner frame member is made of glass. Both outer frame members cannot be removed unless they are removed by moving them along the wide surface of the plate. Also, each inner frame material,
The glass plate cannot be removed unless it is disengaged from the outer frame member by moving it in the direction along the wide surface of the glass plate.

[0011] On the other hand, the external force acting on the window frame, are mostly those which act along the thickness direction of the door or the like, glass and the inner frame member
Since an external force that moves along the wide surface of the sheet plate hardly acts, it is possible to prevent an unexpected situation where the frame material comes off due to some external force without necessarily fixing the frame material with nails or screws. Even if the flange of the outer frame member is opened by a screwdriver or the like, the outer frame member cannot be removed, so that the anti-theft property is improved.

According to the second aspect of the present invention, when each outer frame member is fitted into the window hole, it is held in that state by the third engaging means, which facilitates the assembly and the fixing strength of the outer frame member. There is an advantage that can be improved.
