Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an entrance door frame assembly apparatus in which the connecting ends of an upper frame and a vertical frame are connected by a corner member.

The connection end when assembling the frame of a conventional entrance door is
Generally, an assembly device is employed that abuts and joins the end face of one frame body and the side face of the other frame body.

However, an exterior facing edge is provided on the surface of the entrance door frame to create a decorative effect, and according to the abutment joint of the end face and side surface described above, the surface pattern of the exterior facing edge is discontinuous between the upper frame and the vertical frame. This has the disadvantage that the decorative effect is reduced.

To this end, recent efforts have been made to connect the connecting end surfaces of the frames by cutting them diagonally and butting them together. It is difficult to bond, and even if bonding is possible, the bonding strength is insufficient.

The present invention was developed in view of the above points, and uses two types of L-shaped corner members at the connecting ends of the entrance door frame to easily connect the end faces, and to improve the joint strength. The present invention proposes an assembly device for an entrance door frame that eliminates all the drawbacks of the conventional method.

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

Figures 1 and 2 are front views showing the connected state of the frame;
The figure is a cross-sectional view taken along the line A-A in Figure 2, and Figure 4 is a cross-sectional view of the upper frame.
FIG. 5 is a sectional view taken along the line B--B in FIG. 2, and FIGS. 6 and 7 show each corner member.

In each of the above figures, the present invention has an upper frame 10A and a left and right vertical frame 10.
Corner member mounting grooves 3 and 4 are formed in each outer web 1 and inner web 2 of B and IOB, respectively, and a plate-shaped corner member 11 and an angular L-shaped corner member 12 are fitted into these grooves, respectively. Then, the connecting ends of the frame body 10A and IOB are joined to form an entrance door frame.

In FIGS. 3 to 5, the upper frame 10A and the vertical frame 10
B includes an outer web 1 having a mounting piece 5, an exterior facing edge 6, and a corner part mounting groove 3 along the outer side of the building frame 30, and an inner wall surface 7 and an indoor side on the inner side of the opening of the building frame 30. It is composed of an inner web 2 having corner member mounting grooves 4 on the back side thereof.

As shown in FIG.
A thin plate piece is formed so that it can be inserted freely with a and 3a facing each other.

The other mounting groove portion 4 is formed into a substantially rectangular tube shape, and engagement pieces 4a, 4a are provided in the rectangular tube so as to face each other.

Note that it is possible to change the cross-sectional shape of the mounting groove 4, such as making it completely hollow.

Each frame 10A has the two types of mounting grooves 3 and 4 described above,
As shown in FIGS. 1 and 2, the IOB has its connecting end surfaces cut at approximately 45 degrees and butted against each other, and the plate-shaped groove 3 and the square groove 4 are connected to the adjacent upper frame 10A and vertical frame. They are formed in the same shape at positions facing each other between 10B.

In addition, by forming the exterior facing edges 6 in the same shape at opposing positions between each frame 10A and IOB,
The surface pattern can be made continuous.

Note that a transom panel 21 is provided on the inner web 2 of the upper frame 10A.
A mounting recess 22 is provided in the middle of the inner wall surface 7, and a door stop 24 of the door 23 is formed in the inner web 2 of the vertical frame 10B so as to protrude from the inner wall surface 7.

Next, the plate-shaped L-shaped corner member 11 described above has a plate thickness 11a that fits the U-shaped groove 3a in the corner member mounting groove 3 of each frame 10, as shown in FIG. , is formed of an L-shaped thin plate piece having a plate width 11b that is the same width as the width between the opposing grooves 3a, 3a.

Note that the length of one piece of the plate is determined in consideration of the length of fitting into the mounting groove 3.

The angular L-shaped corner member 12 has an angular shape that substantially conforms to the cross-sectional shape of the corner member mounting groove 4 of each frame 10, as shown in the front view of FIG. 6A and the bottom view of FIG. 6B. It is formed by connecting insert pieces 13.13 with an L-shaped cross section.

Each insertion piece 13.13 is provided with retaining grooves 14.14 facing each other, into which the engaging piece 4a of the mounting groove 4 is inserted and engaged, and a groove communicating with the groove 15 formed on the inner surface. The hole 16 and the screw holes 17 and 17 are arranged in series.

The above-mentioned L-shaped corner members 11 and 12 are used to connect the frame bodies 10A and IOB as shown in FIG. At the same time as inserting into the mounting groove 3, the square corner part 1
2 into the square corner member mounting groove 4 of each frame 10, the frames 10A and IOB are inserted as shown in FIG.
The ends are joined together.

At this time, the engagement pieces 4a, 4a of the mounting groove portion 4 are engaged with the engagement grooves 14.14 of the corner member 12.

After the joint end surfaces of each frame 10A and IOB are brought into contact as shown in FIG.
Screw the screws 18.18 into the screw holes 17 from the inside of the upper frame 10A to fix the insertion piece 13 and the upper frame 10A, and then from the through hole 16 of the insertion piece 13 of the fixed upper frame 10A. Vertical frame 10B
The horizontal insertion piece 13 and the vertical frame 10B are fixed by screwing the screw 19 into the screw hole 20 located in the groove 15 of the insertion piece 13.

Of course, the screws 18 and 19 may be attached to the vertical insertion piece 13.

On the other hand, the plate-shaped corner member 11 and each frame 10 can also be fixed with screws 25 as shown in FIG.

As described above, each corner member 11, 12 and the frame 10 need only be connected to at least one of them.

As described above, in the present invention, two corner member mounting grooves are formed in each frame body, and plate-shaped and square L-shaped corner members are inserted into these grooves to connect and connect the upper frame and the vertical frame. Therefore, the oblique end faces of each frame can be easily joined to the end faces, and after joining and connecting, one of the corner members is fixed to the frame with screws, so the connection is made stronger. .

Furthermore, since the end face connection between the two corner members is achieved by installing each corner member in a groove on the two orthogonal surfaces of the outer and inner surfaces of the building frame, the connection reinforcement effect is further improved. .
