[0002]

2. Description of the Related Art Conventionally, a door frame having a door stop to which a packing material is attached has been used in order to exert functions such as airtightness and soundproofing of a door. In order to attach the packing material to the door stop, as shown in FIGS. 7 and 8 , the flat piece of the packing material a is connected to the door receiving surface c of the door stop b.
A method of fixing by implanting Tucker d in the state of being abutted to each desired interval in the longitudinal direction toward the doorstop b from the packing material a, as shown in FIG. 9, the doorstop b door A method is employed in which a concave groove e is cut in an intermediate portion of the receiving surface c, and most of the packing material a made of a soft material and having an appropriate sectional shape is fixed in the concave groove e.

[0003]

However, when the packing material a is fixed by the tucker d as in the former case,
Since it is difficult to keep the packing material a tensioned in the length direction when driving the tucker d, the packing material a between the adjacent tuckers d and d is not shown.
As shown in FIG. 8 , there is a possibility that the packing material a may float due to relaxation. When such a floating portion occurs, when the door comes into contact with the packing material a, the adhesion of the door to the packing material fixing portion by the tucker d becomes poor, and there is a problem that the airtightness and the soundproofness are reduced.

On the other hand, according to the latter packing material mounting structure, it takes time and effort to accurately and precisely cut the packing material embedding groove e in the middle of the door receiving surface c of the door stop b. Instead, in order to firmly attach the packing material a to the concave groove e, it is necessary to provide a special receiving member f such as a packing material retaining member in the concave groove e. Further, the work of fitting the packing material a into the concave groove e is troublesome, and it is difficult to mount the packing material a with a certain height over the entire length from the concave groove e with high accuracy. It is easy to get out of order.

[0005] As described above, if the packing material mounting accuracy is deviated, or if the packing material mounting portion is provided in the middle portion of the door receiving surface c of the door stop b as described above, the door may be damaged. There is a problem that the packing material a is easily detached from the concave groove e due to the impact force frequently received every time the opening and closing are performed.
An object of the present invention is to provide a door frame capable of completely solving such a problem.
