DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixed window frame for attaching a window plate such as a glass plate to a window hole provided in a door or a wall.

[0002]

2. Description of the Related Art As a prior art relating to a fixed window frame provided on a door or a wall, Japanese Utility Model Publication No. 56-4789 discloses a frame material provided with a flange on the front side of a door or the like, and a door or the like. The other frame member provided with a flange on the back side is fitted into each inner surface of the window hole along the thickness direction of the door or the like, and is provided on the male engagement portion provided on one frame member and the other frame member. It describes that the window plate is sandwiched and fixed between both frame members by engaging with a female engaging portion. In addition, real Kimiaki 4
Japanese Patent Application Laid-Open No. 4-29489 describes a window frame structure in which three frame members are set as one set.

[0003]

In these two publications, the frame members are integrally held by utilizing the hooking engagement of a claw formed on the frame member.
Since it is fitted into the window hole along the thickness direction of the door or the like, for example, when a large pressing force acts on the surface of the window plate and a force along the thickness direction of the door or the like acts on the frame material, the frame is There was a risk that the material would fall out of the window hole. In addition, when the flange is pryed off with a screwdriver or the like, the frame material can be easily removed, so that there is a problem that the anti-theft property is inferior. 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 is reduced.

The object of the present invention is to solve these problems.

[0005]

The window frame of the present invention comprises two outer frame members disposed between each inner peripheral surface of the window hole and each outer peripheral surface of the window plate, and a window plate. It has two inner frame members sandwiched from both sides, and the outer frame members are a first outer frame member having a flange which contacts a surface of a door or a wall, and a flange which contacts a back surface of a door or a wall. And these two outer frame members are attached by fitting them into window holes along the thickness direction of the door or wall.

On the other hand, one of the inner frame members is moved to one of the inner frame members and the two outer frame members, and one of the inner frame members is moved toward the outer frame member along the wide surface of the window plate. And first engaging means for engaging the three members with each other to hold both outer frame members irreversibly and holding one inner frame member irreversibly from the window plate, and the other of the two inner frame members When the other inner frame material is moved toward the outer frame material along the wide surface of the window plate, the inner frame material and the corresponding outer frame material (and / or one inner frame material) A second engaging means is provided for engaging with each other and holding the other inner frame member so as not to be separated from the window plate.

[0007]

In the present invention, first, each outer frame member is mounted on the inner surface of the window hole, and then one inner frame member is attached. The window plate can be mounted in the window hole by the order of mounting the inner frame material.

Since each outer frame member is held 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 window plate, the inner frame member is not separated from the window. Both outer frame members cannot be removed unless they are moved and removed in the direction along the wide surface of the plate. In addition, the window plate cannot be removed unless each inner frame member is moved in a direction along the wide surface of the window plate to release the engagement with the outer frame member.

On the other hand, most of the external force acting on the window frame acts along the thickness direction of the door or the like, and almost no external force acts to move the inner frame member along the wide surface of the window plate. Not necessarily fix the frame material with nails or screws, etc.
It is possible to prevent an unexpected situation where the frame material comes off due to some external force, and even if you try to pry the flange of the outer frame material with a driver etc., the outer frame material will not come off,
Theft resistance is also improved.

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