Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a lighting small window of a steel plate door, and more particularly to a mounting structure of a small window frame.

[0002]

2. Description of the Related Art As shown in FIG. 4, a partition door or the like is often provided with a small window for lighting. Generally, an opening for a window is prepared in the door body 1, a small window frame body 2 is attached to the opening edge, and a window glass 3 is fitted in the small window frame body 2.

A conventional small lighting window of a steel plate door will be described with reference to FIGS.

The door body 1 shown in FIG. 5 and FIG. 6 is one in which a steel plate 5 is attached to a strength frame 4 made of a steel plate. In the drawings, 6 is a window opening previously formed in the door body 1.

The small window frame 2 is fixed to the force bone 4 that borders the window opening 6. The small window frame 2 comprises an outer frame 7 made of a steel plate and an inner frame 8 made of a steel plate.

The outer frame 7 is a frame surface 4 of the force bone 4.
The seat frame 9 is in contact with a and the outer frame part 10 has an inverted concave cross section that continuously rises up from the seat part 9. Stuck to. A lower end portion of the outer side surface 10a of the outer frame portion 10 is superposed on the outer steel plate 5.

The inner frame 8 has an inverted concave cross-section similar to the outer frame portion 10, and the inner frame 8 faces the outer frame portion 10 to form a groove 12 for fitting a window glass. To do. One lower end of the inner frame 8 is placed on the seat 9, and the other lower end overlaps the inner steel plate 5. The inner frame 8 is fixed to the force bone 4 by screws (not shown).

When the window glass 3 is to be fitted, the outer frame 7 is first attached, the window glass 3 is attached to the outer frame 7, and the inner frame 8 is fixed to complete the process.

FIG. 7 shows a case where the strength bone 15 is made of wood and the outer frame 13 and the inner frame 14 constituting the small window frame 2 are made of aluminum.

The outer frame 13 has the same shape as that of the outer frame 7, and is fixed to the force frame 15 with screws 16. The inner frame 14 is provided so as to abut against the outer frame 13, and the inner frame 14
Is similarly fixed to the force bone 15 with a screw.

[0011]

In the above-mentioned conventional small window of the steel sheet door, when the outer frame 7 is mounted, the outer frame 7 is fixed by screws, and at the work site, the outer frame is drilled by a drill or mounted by the screw. Work had to be done, and the workability was troublesome and time consuming. or,
There is a problem that cutting dust and dust are generated during the drilling work by the drill, and the working environment is deteriorated.

[0012] In view of the above situation, the present invention is designed so that the external frame can be attached without drilling work or attaching work with screws at the work site.

[0013]

According to the present invention, an outer frame and an inner frame are provided on a frame edge of a window opening formed in a door body, and a window glass is held by the outer frame portion of the outer frame and the inner frame. In a small lighting window of a steel plate door forming a groove for use, a tongue piece inclined toward the frame edge side is formed in a seat portion formed continuously with the outer frame portion of the outer frame, and a window opening A locking hole is formed in the frame edge, the outer surface of the outer frame portion is brought into contact with the steel plate of the door body, and the tip of the tongue is brought into contact with the hole edge of the locking hole to attach the outer frame to the door body. It is characterized by being attached.

[0014]

The outer frame is attached to the door body by holding the steel plate and the locking hole between the outer surface and the tongue. Therefore,
Mounting the external frame eliminates drilling and screwing work, improving workability.

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

The embodiment shown in FIGS. 1 and 2 corresponds to the conventional example shown in FIGS. 5 and 6, and the components similar to those in the conventional example are designated by the same reference numerals and their description is omitted. Omit it.

A rectangular locking hole 18 is preliminarily formed in the strength bone 4 when the door body 1 is manufactured, and a tongue piece 19 that is inclined to the strength bone 4 side by press working is previously formed in the seat portion 9 of the outer frame 7. Set up. The distance between the tip of the tongue piece 19 and the inside of the outer side surface 10a is set to be slightly smaller than the distance between the edge of the locking hole 18 and the surface of the steel plate 5.

When the outer frame portion 10 is attached to the door body 1, first, the tongue piece 19 is aligned with the locking hole 18, and the tip of the tongue piece 19 is brought into contact with the hole edge of the locking hole 18. Further, the lower end portion of the outer side surface 10a is slightly spread and brought into contact with the steel plate 5.

Due to the elasticity of the outer frame portion 10, the outer frame 7 is held by the door body 1. Therefore, the external frame 7 can be attached to the door body 1 without the need for a screw and without the need to form a hole for screw insertion. The inner frame 8 is fixed with screws as in the conventional case.

The outer frame 7 is pressed by the inner frame 8 and the fitted window glass 3 prevents the outer frame 7 from rising, so that the outer frame 7 does not come off from the door body 1.

Further, the one shown in FIG. 3 corresponds to the one shown in FIG. 7, and the outer frame 13 and the inner frame 14 are formed of an aluminum drawing material.

A locking hole 20 is preliminarily formed in the upper surface of the force bone 15, and a tongue piece 19 is formed in the seat portion 9 of the outer frame 13 by inclining by press working. The outer surface 13a of the outer frame 13 is engaged with the steel plate 5 of the door body 1 in a state where the tongue piece 19 is fitted into the locking hole 20 and the tip of the tongue piece 19 is brought into contact with the wall surface of the locking hole 20.

The outer frame 13 is held by the door body 1 by the elasticity of the outer frame portion 10. The inner frame 14 is fixed to the force bone 15 with screws.

[0024]

As described above, according to the present invention, when the external frame is mounted, the drilling work by the drill is unnecessary, and since the screw is not used for the mounting, the workability is improved and the working time is shortened. The cost can be reduced, and since dust is not generated due to drilling, the work environment is improved and other excellent effects are exhibited.
