Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a window frame provided on a wooden fire door and a method of assembling a glass window.

[0002]

2. Description of the Related Art Fire doors are generally made of metal, but wooden fire doors may be used to make a living space comfortable or according to preference. The fire door is filled with rock wool as a core material to protect it from fire, but as shown in Fig. 5, a glass window is placed at the center of the fire door (a).
There are cases where (b) is provided. Of course, the glass plate is made of ultra heat-resistant crystallized glass or netted glass that can withstand high temperatures in the event of a fire.

However, this glass plate must be fitted to a window frame formed on the door so as not to come off, and FIG. 6 shows a glass plate attached to a window frame (c) provided in a conventional fire door.
(D) is shown in (a), and the glass plate (d) is fitted in the window frame (c). Between the window frames (c) and (c), glass receivers (e), (e),... Having a U-shaped cross section are attached, and the glass receivers (e), (e),. The edge of d) fits.

The glass receiver (e) is made of metal, and is made of metal so that the glass plate (d) does not come off even if the wooden window frame (c) burns down due to high heat in a fire. , (E) ... As shown in FIG. 6 (a), the glass plate (d) is inserted obliquely into one of the glass receivers (e), and then partially returned in the opposite direction to be fitted as shown in FIG. 6 (b). After being fitted in the glass receivers (e), (e), it is caulked so as not to come off. However, since the fire door targeted by the present invention is made of wood, the metal glass receiver (e) is used. , (E)... Must be increased so that the width M of the window frame (c) is not exposed.

The size M of the window frame of the conventional fire door is about 25 mm, which is larger than the size of the window frame other than the fire door is about 16 mm. Therefore, the appearance of the fire door is impaired, and it is preferable to make the window frame size the same as a general door. In particular, when a general door is installed nearby, the window frame
The difference in the dimensions of (c) becomes noticeable.

[0006]

As described above, the window frame structure of the conventional wooden fire door has the above-mentioned problems. The problem to be solved by the present invention is this problem, and provides a window frame structure in which the size of the window frame does not increase. Also provided is a method of attaching a glass window to a wooden fire door.

[0007]

In order to provide a glass window on a wooden fire door, the surface of the window frame to be surfaced must be wooden, but the wooden window frame is burned down by the high heat of a fire. Therefore, a metal glass receiver is required inside. Therefore, although the basic structure is the same as that of the conventional one, in the present invention, the width of the glass receiver is reduced so that the glass receiver can be covered so that the glass receiver is not exposed even with a general window frame.

However, the glass plate cannot be fitted unless the glass receiver has a certain width dimension. However, in the present invention, the glass plate is not fitted to the glass holder previously mounted, but is attached to the edge of the glass plate. The structure is such that it is attached to the window space formed in the door with the receiver fitted. A screw groove is formed in the glass receiver, and the glass receiver fitted in the window space together with the glass plate is moved so that the screw previously attached is fitted into the screw groove so as not to come off.

When the number of glass receivers is equal to the number of attached screws, or a long glass receiver is used, a thread groove for fitting a plurality of screws may be formed in the glass receiver. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

[0010]

FIG. 1 is an embodiment showing a window frame structure of the present invention. In FIG. 1, reference numeral 1 denotes a glass plate, 2 denotes a window frame, and 3 denotes a glass receiver. The basic structure of the window frame in which the glass plate 1 is fitted as shown in FIG. However, as shown in (a), the mounting method of the glass plate 1 is different, and the glass receivers 3 are fitted to the window space 4 while being temporarily fixed to the edge of the glass plate 1.

The window frame 2 is mounted on one side of the window space 4, and screws 6, 6,... Are screwed into the inner surfaces 5, 5,. Then, the glass plate 1 on which the glass receivers 3, 3,... Are arranged fits into the window space 4, and the glass receivers 3, 3,.

FIG. 2 shows a specific example of the glass receiver 3, which has a U-shaped cross section having both side pieces 7, 7 and a bottom piece 8, and an edge of the glass plate 1 is provided between both side pieces 7, 7. It can be fitted and a thread groove 9 is formed from one end of the bottom piece 8. The glass receivers 3, 3,... Are attached to both side edges of the glass plate 1 as shown in FIG.
It is stopped at. Further, the glass receivers 3 and 3 may be attached to the upper and lower edges of the glass plate 1 as needed.

By the way, the glass receivers 3, 3.
The glass plate 1 temporarily fixed at 1, 11,... Is fitted into the window space 4, but the screws 6, 6,. 3 ... is different. .. Do not hit the screws 6, 6,..., And after the glass plate 1 is fitted in the window space 4, the tapes 11, 11,. Screws 6, 6 in screw grooves 9, 9, ... of glass receivers 3, 3, ...
Are fitted into the window spaces 4.

Here, the width of the screw groove 9 is such that the head of the screw does not come off. By attaching the glass receivers 3, 3,... To the window space 4, the glass plate 1 does not come off, and the window frame 2 is fitted on the opposite side as shown in FIG. The side piece width of the glass receiver 3 shown in FIG. 2 is small. Therefore, the width dimension M of the window frames 2, 2 covering the glass receivers 3, 3,. They can be the same size.

FIG. 4 shows another specific example of the glass receiver 3. The glass receiver 3 has a length extending substantially over the entire length of the side edge of the glass plate 1.
9b is formed. The screw groove 9a has an inlet groove 1
0a are formed continuously, and the screw groove 9b is formed in the inlet groove 10a.
b is formed continuously. The glass receiver 3 is attached to the side edge of the glass plate 1, and screws 6, 6,... Screwed from the inlet grooves 10a, 10b to the inner surfaces 5, 5 of the window space 4.
Can enter, and the screws 6, 6,... Fit in the screw grooves 9a, 9b by descending the glass receiver 3.

As described above, in the window frame structure of the wooden fire door according to the present invention, the glass receiver is fitted to the window space with the glass receiver attached to the edge of the glass plate, and the screw is fitted to the screw groove of the glass receiver. Thus, the following effects can be obtained.

[0017]

According to the window frame structure of the present invention, the glass receiver is fitted to the window space with the glass receiver attached to the edge of the glass plate. When the glass receiver is fitted to the window space, the glass receiver is lowered and formed on the bottom of the glass receiver. Screw is inserted into the thread groove. Therefore, the side piece width of the glass receiver may be small, and as a result, the size of the window frame that covers the glass receiver may be small, and the window frame of the wooden fire door is preferable in appearance. That is, even with a fire door, there is no difference in appearance from a general wooden door.
