Description

[Detailed Description of the Invention] The present invention relates to the structure of an entrance door frame formed by obliquely cutting the ends of an upper frame and left and right vertical frames and joining the end faces.

In recent years, the ends of the upper frame and the left and right vertical frames made of extruded aluminum have been joined by cutting the ends at an angle of about 45 degrees to make the surface pattern continuous, as shown in Figure 6. I have to.

However, a doorstop wall 3 is generally provided on the inside surface of the vertical frame 1, and when the end of the vertical frame 1 is cut diagonally, the upper end of the doorstop wall 3 is also cut diagonally, so the vertical At the end surface connection between the frame 1 and the upper frame 2, a triangular gap 4 was formed as shown by the dotted line, which extremely degraded the appearance.

On the other hand, it is also possible to cut the upper end of the door stop wall 3 horizontally so that it touches the lower surface of the upper frame 2, but it is also possible to make two cuts, an oblique cut and a horizontal cut, at the end of the vertical frame 1, which is a form material. This resulted in a significant decrease in work efficiency and could not be adopted.

The present invention was developed in view of the above points, and the gap between the vertical frame and the upper frame, which is created by diagonally cutting the entire upper end of the vertical frame, is closed by using an appropriate closing material. By doing so, we propose an entrance door frame that easily prevents deterioration in the external appearance of the frame.

The present invention will be described below based on embodiments shown in the drawings.

FIG. 1 is a front view showing the joint end of the frame of the present invention.

In the same figure, the present invention shows that the upper end of the door stop wall 3 of the rotating door protruding from the inner surface of the vertical frame 1 is cut at an oblique end face 1a of the vertical frame 1.
Along with continuous cutting at approximately 45 degrees along the wall 3, a triangular gap 4 created between the cut end surface 3a of the wall 3 and the upper frame 2 is fitted with a closing material 5 having a shape that matches the gap. This is what they are trying to do.

The door stop wall 3 is located at the second
As shown in this figure and in FIG. 3, which is an exploded view of the main part, the vertical frame 1 has a plate-shaped piece projecting at a substantially right angle in the longitudinal direction of the inner surface of the vertical frame 1.

Further, in the longitudinal direction of the center of the plate-like piece, there is a groove 6 into which the doorstop backing material 7 is attached.

As shown in FIG. 5, the closing material 5 attached to the upper cavity 4 is attached to the front surface of the backing member 8 having a stepped shape.
At the same time, a triangular doorstop part 9 is formed to fit the doorstop part 9, and a groove 10 having a shape that fits the groove 6 of the doorstop wall 3 is formed in the center longitudinal direction of several doorstop parts 9. A horizontal mounting piece 11 with a screw hole 12 bored in the center is provided.

The closing material 5 is installed in the gap 4 of the end surface joint of the frame 1゜2 as shown in FIG. It is connected to the top surface of the vertical frame door stop wall 3, the backing member 8 is in contact with the back surface of the door stop wall 3, and the horizontal mounting piece 11 is in contact with the bottom surface of the upper frame 2, as shown in FIG. Insert screw 13 into screw hole 12 as shown.
Then screw it onto the upper frame 2.

Note that a backing material 14 is attached to the groove 10 of the door stop 9 in the same way as the door stop wall 3.

By providing the backing member 8 on the back surface of the door stop 9 as described above, the door stop 9 can be more firmly attached to the door stop wall 3.

The mounting piece 11 may not be provided on the upper surface of the backing member 8, but may be provided on the side surface of the backing member 8 and fixed to the vertical frame 1 with screws.

Next, returning to Fig. 1, the end surface connection between the vertical frame 1 and the upper frame 2 is 1
This is accomplished by a square-shaped connecting piece 15 and a plate-like connecting piece 16.

That is, as shown in FIGS. 2 and 4, the square connecting pieces 15 are fitted into the square tubular grooves 15a, 15a formed on the inner webs of each frame 1, 2, and the thin tubes formed on the outer webs are inserted into the square tube grooves 15a, 15a. By fitting the plate-like connecting pieces 16 into the width grooves 16a, 16a, the end faces of the frames 1, 2 can be easily and firmly joined.

After fitting, screws 17 and 18 are screwed into the square connecting piece 15 to further strengthen the connection between the frames 1 and 2.

Note that the above-described closing material 5 can also be provided on the above-described square connecting piece 15 itself.

That is, in the positional relationship shown in FIG.
Alternatively, it is also possible to integrally mold the doorstop part 9 of the closing member 5 with the square connecting piece 15.

In contact with the backing materials 7 and 14 shown in FIGS. 2 and 4 is a door 19 that rotates to open and close.

Note that the backing material may be attached to i6 and i10 continuously.

Since the present invention is constructed as described above, the triangular gap in the upper part of the doorstop wall that is created when the ends of the vertical frame and the upper frame are cut diagonally and the end faces are joined can be filled with a closing material that has a doorstop part. By attaching it, it is possible to reliably close the gap, and it is possible to easily prevent the appearance from deteriorating due to the gap.

Moreover, by providing the same backing material installation groove on the closing material as on the doorstop wall, the backing material can be attached continuously to the doorstop wall, making it possible to more accurately receive the door that rotates to open and close, and to ensure airtightness. Get the effect you want.
