By press-contacting both end portions of the metal fittings 5 to the locking pieces 4 of the frame 2, the receiving metal fittings 5
Since the bracket 5 is fixed in the frame body 2, there is no need for welding and the receiving metal fitting 5 is attached to the frame body 2 by tightening the presser screw 6.
It can be fixed inside.

【Example】

The present invention will be explained in detail below with reference to Examples. The door frame 1 is formed by assembling a plurality of frames 2, 2, etc. made by extrusion molding of aluminum, etc., but in the embodiment shown in FIG.
2a is constructed by constructing a horizontal frame 2b between the upper ends thereof. Each frame 2 has locking pieces 4 facing each other at both ends of a main body piece 3 having an open back and a U-shaped cross section.
4 are extended, and a door stop piece 13 is integrally provided on the side of each frame 2 to protrude. Of each frame 2, the upper end of the vertical frame 2a and both ends of the horizontal frame 2b are 4.
It is cut diagonally at an angle of 5 degrees, and the end surfaces of the vertical frame 2a are butted against both end surfaces of the horizontal frame 2b, and the horizontal piece 15 of the L-shaped corner metal % 14 is attached to the horizontal frame 2b. The door frame 1 is assembled by connecting the frame bodies 2 by inserting the vertical pieces 16 into the upper ends of the vertical frames 2 and fixing them with screws, etc., into the left and right ends of the door frame 2. In FIG. 3, reference numeral 21 denotes a base metal fitting that is attached to the lower end of the vertical frame 2a to fix the lower end of the door frame 1 to the floor. Next, a latch receiving seat 8a (also called a strike) used to receive a latch attached to the door is attached to the frame 2 of the door frame 1 formed as described above as an attached member 8.
The latch receiving seat 8a is formed by providing the main body box part 19 on the back of the seat plate 24, and the latch receiving seat 8a is first attached to the latch receiving seat 8a.
1, an opening 7 of approximately the same size as the seat plate 24 of the latch receiving seat 8a as shown in FIG. 1 is cut out in the frame body 2. Further, as shown in FIG. 1, the receiving fitting 5 has a substantially U-shaped cross section with an opening on the back side, and has a fixing screw hole 17 and a mounting hole 18. Furthermore, an insertion opening 20 into which the main body box portion 19 of the latch receiving seat 8a is inserted is provided. This receiving metal fitting 5 is inserted into the frame 2 from the lower end of the frame 2, arranged in the frame 2 at the opening 7, and then inserted into the fixing screw hole 17 from the 7th side of the receiving metal fitting 5. By screwing in the cap screw 6, the tip of the cap screw 6 is brought into pressure contact with the inner surface of the frame 2 as shown in FIG. Press it against the inner surface of 4. In this way, the receiving metal fitting 5 can be fixed within the frame 2, and the fixing position of the receiving metal fitting 5 can be finely adjusted by loosening the presser screws 6. Next, as shown in Fig. m2, the latch receiving seat 8a is fitted into the opening 7 from the front side of the frame 2, and the latch receiving seat 8a is passed through the through hole 23 of the latch receiving seat 8a.
By screwing into the mounting screw hole 18 of the receiving fitting 5, the latch receiving seat 8a can be fixed to the receiving fitting 5. In this way, the latch receiving seat 8a can be attached to the frame body 2 via the receiving metal fitting 5. Here, the distance between the surface of the frame body 2 and the surface of the receiving metal fitting 5 is adjusted to the thickness of the seat plate 24 so that the surface of the seat plate 24 of the latch receiving seat 8a is flush with the surface of the frame body 2. They are adjusted so that they are the same, and the id slanted piece 25 provided on one edge of the seat plate 24 is designed to protrude from the opening 7 of the frame body 2. FIG. 4 shows an embodiment in which a lower hinge member 8b used for rotatably supporting the door is attached as an accessory member 8, and the lower hinge member 8b has a pivot 27 at the end of the fixed piece 26. The provided door receiving piece 28 is extended to create a formal appearance. *An opening 7 of approximately the same size as the fixing piece 26 is formed in the frame 2, and the receiving metal fitting 5 is fixed in the opening 7 with the presser bolt 6 in the same manner as described above. Then, attach the fixing piece 26 of the lower hinge 8b to the opening 7.
Mounting screw 9 inserted into the hole 23 of the fixing piece 26
By screwing into the mounting screw hole 18 of the receiving fitting 5, the lower hinge member 8b can be fixed to the receiving fitting 5. In this way, the lower hinge member 8b can be attached to the frame body 2 via the receiving fitting 5, and the frame body 2 is attached so that the surface of the fixing piece 26 is flush with the surface of the frame body 2.
The distance between the surface of the door and the surface of the receiving metal fitting 5 is adjusted to be the same as the thickness of the fixing piece 26, and the door receiving piece 28 is made to protrude through the opening 7 of the frame 2. As one of the attached members 8, the upper hinge member 8c can also be attached to the frame body 2 using the receiving fitting 5 in the same way as the lower hinge member 8b. In this case, the opening 7 needs to be provided so as to match both the frame 2 and the corner fitting 14. After attaching the member 8 to the base as described above, as shown in Fig. 3(b).
The door frame 1 formed as shown in FIG.
The door 30 is attached as shown in FIG. 5 with the door 30 rotatably supported by the door c.

【Effect of the invention】

As described above, in the present invention, the receiving fitting is disposed inside the frame, the tip of the cap screw screwed into the receiving fitting is pressed against the inner surface of the frame, and both ends of the back of the receiving fitting are attached to the frame. Since the receiving metal fitting is fixed in the frame body by pressing against the locking piece of the body, the receiving metal fitting can be fixed in the frame body by tightening the cap screw. There is no need to perform welding for fixing, and even if the frame is made of a material that is difficult to weld, such as aluminum, the receiving metal fitting can be fixed to the frame and attached parts can be attached.
