【Example】

 As shown in FIG. 1 and FIG. 2, the plastic door frame of the present invention is a newly created one mainly relating to the structure and mounting method of the door frame used when replacing the door frame. In the door frame 1 of the present invention, the front frame 11 and the rear frame 12 are fitted and coupled to each other.

The front frame 11 has a F-shaped cross section and has a gap 113 between the outer plate 111 and the inner plate 112. The inner plate 112 is longer than the outer plate 111. The front end of the frame 11 is provided with a groove 114 that can be fixed with a nail or screw, and the head of the nail or screw is covered with a U-shaped groove lid 115.

The rear frame 12 also has an F-shaped cross section, and has a structure in which a gap 123 is provided between the outer plate 121 and the inner plate 122, and the front frame 11 is provided in the gap 123 of the rear frame 12. The inner plate 112 of the rear frame 12 is fitted, and the thickness of the outer plate 121 of the rear frame 12 is set so as to fit into the gap 113 of the front frame 11, and the end of the rear frame 12 can be fixed with nails or screws. A groove 124 is provided, and the head of the nail or screw is covered with a U-shaped groove lid 125.

After cutting the front frame 11 and the rear frame 12 into appropriate lengths, they are fitted and joined to each other from the front and rear of the frame 0 of the old door, respectively. That is, the outer plate 121 of the rear frame 12 is inserted into the gap 113 of the front frame 11, the inner plate 112 of the front frame 11 is inserted into the gap 123 of the rear frame 12, and originally fixed to the sill. Adjust the width covered by the front frame 11 and the rear frame 12 by freely expanding and contracting according to the width of the old door frame 0. Moreover, the step and width formed by the inner plate 112 of the front frame 11 and the inner plate 122 of the rear frame 12 can cover the outer surface of the frame 0 of the old door originally fixed to the sill. Further, nails or screws 2 are driven into the grooves 114 and 124 to fix the front frame 11 and the rear frame 12 to the frame 0 of the old door, and then they are fixed with the U-shaped groove lids 115 and 125, respectively. Covering the grooves 114 and 124 (as shown in FIGS. 3 and 4) The door frame having a perfect appearance is constructed as described above.

Furthermore, the present invention also has a structure (shown in FIG. 5) having a different cross section due to the structure of the frame 0 of the old door. In FIG. 5, the old door frame 0 has a larger lip than in the previous embodiment. Therefore, the front frame 11 and the rear frame 12 are appropriately structurally modified to meet the requirements of aesthetics and practical use. That is, the ends of the front frame 11 and the rear frame 12 are widened, right-angled cover plates 116 and 126 are provided, and by fitting with the right-angled plate 13, the edges of the frame 0 of the old door are covered, and the actual Meet demand.

[0011]

[Effect of device]

 With the structure of the present invention, it is possible to insert the front and rear frames into each other in a mating manner so as to cover the frame of the old door that is originally fixed to the sill. The work to remove the door can be omitted, and at the same time, the destruction when removing the old door can be prevented. INDUSTRIAL APPLICABILITY The present invention has an effect that it has excellent bondability, has a strong structure, and has practical value.
