Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a door frame used for a soundproof door of a house or the like.

[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 make the door exhibit functions such as airtightness and soundproofing. Then, in order to attach the packing material to the door stop, as shown in FIGS. 8 and 9, the flat piece of the packing material a is attached to the door receiving surface c of the door stop b.
And a tucker d is fixed in the longitudinal direction from the packing material a toward the door stop b at desired intervals, or as shown in FIG. A method is employed in which a concave groove e is cut in the middle of the receiving surface c, and most of the packing material a made of a soft material and having an appropriate cross-sectional shape is fixed in the concave groove e in an embedded state.

[0003]

However, when the packing material a is fixed by the tacker d as in the former case,
When the tacker d is driven, it is difficult to hold the packing material a in a tensioned state in the lengthwise direction. Therefore, as shown in FIG. 9, the packing material a is located between the adjacent tackers d and d. In addition, there is a possibility that floating may occur due to the loosening of the packing material a. 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 is deteriorated, and there is a problem that airtightness and soundproofing are deteriorated.

On the other hand, according to the latter packing material mounting structure, it takes much time and labor to accurately cut the packing material burying groove e in the intermediate portion of the door receiving surface c of the door stop b in a straight line. 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 for preventing the packing material from coming off in the concave groove e. Further, the work of fitting the packing material a into the groove e is troublesome, and it is difficult to accurately mount the packing material a so as to project from the groove e by a certain height over the entire length. It is easy to get out of order.

As described above, if the packing material mounting accuracy is incorrect, or if the packing material mounting portion is provided in the middle of the door receiving surface c of the door stop b as described above, There is a problem that the packing material a is likely to come off the concave groove e due to the impact force that is frequently received at each opening and closing.
An object of the present invention is to provide a door frame that can completely eliminate such problems.

[0006]

In order to achieve the above object, the door frame of the present invention is, in the first claim, a door frame main body having a door stop projecting at a central portion of an inner surface, and a door frame. In a door frame composed of a mounted packing material, the packing material is connected to the inner surface of the door frame main body and the door receiving surface of the door stop, which is substantially perpendicular to the inner surface, at substantially right angles to each other. And a door contact packing made of a soft material is integrally provided on at least the hard mounting piece that is brought into close contact with the door receiving surface of the door stop, and the inside of the door frame body is provided. A fixing piece portion is provided at the base end of the hard mounting piece portion closely contacted with the surface in the extending direction from the base end, and further, at the base end of the door stopper, the inner surface of the door frame body is provided. A narrow groove that opens along the direction is cut, and the groove of the packing material is fixed in this groove. Inserting the piece parts, but has a fixed structure.

According to the second aspect of the invention, in a door frame composed of a door frame main body having a door stop projectingly provided in the center of the inner surface and a packing material attached to the door stop, the packing material is the door frame. At least a door receiving surface for a door is provided with hard mounting pieces that are in close contact with the inner surface of the main body and a door receiving surface for a door contact that is substantially perpendicular to the inner surface. A door contact packing made of a soft material is integrally provided on the hard mounting piece that is in close contact with the base, and the base end of the hard mounting piece that is in close contact with the door receiving surface is extended from the base end. A fixed piece portion is provided so as to project toward the door. Further, a narrow groove groove that opens in a direction along the door receiving surface is formed at the base end of the door stopper, and the packing material is provided in the groove groove. It has a structure in which the fixing piece portion of (1) is inserted and fixed.

[0008]

[Operation] When the packing material is attached, when the fixing piece of the packing material is inserted into the groove provided at the base end of the door stop, the hard mounting piece that is continuous to the right angle of the packing material and the inner surface of the door frame body The door receiving surface of the door stop, which is perpendicular to the inner surface, closely contacts with accuracy. When the fixing piece of the packing material is fixed in the groove, since the fixing piece projects in the extension direction of the hard mounting piece that is in close contact with the inner surface of the door frame body, the packing material will not hit the door. The fixing piece portion firmly prevents the door from rising from the receiving surface.

Further, since the groove is formed in the base end portion of the door stop in the direction along the inner surface of the door frame body or the door receiving surface, it can be easily and accurately machined straight. Since the fixed piece portion embedded and fixed in the groove is provided in the extension direction of the hard mounting piece portion that is in close contact with the inner surface of the door frame body or the door receiving surface, warping or twisting is unlikely to occur. Not only is the mounting accuracy improved, but the door does not directly contact the mounting portion, so that the door is hardly subjected to frequent impact forces due to opening and closing of the door. Therefore, it is possible to provide a highly durable door frame that always maintains a precise and strong mounting state.

In the structure, after the groove 3 is formed in the door stop 2 in advance, the door stop 2 may be fixed to the door frame body 1.
In this case, a part of the door stop 2 is fixed in a state of being embedded in the door frame body 1 as shown in FIG. 3, but a part of the groove 3 is embedded inside from the inner surface 1a of the door frame body 1. It may be inserted, and in short, the groove 3 may be opened over the entire length in the direction along the inner surface 1a of the door frame body 1.

Further, as in the door stop 2 shown in FIG. 4, the door receiving surface 2a side having a small space from the portion fitted into the fitting groove 1b of the door frame main body 1 is formed thickly, The groove 3 may be formed between the end surface 2b of the thick portion and the inner surface 1a of the door frame body 1. In this case, it is preferable that the end surface 2b is formed as an inclined end surface such that the groove 3 gradually narrows toward the opening end.

Reference numeral 4 is a long packing material formed in the shape of a right-angled triangle having a hollow cross section, and two sides connected to the right angle are the surface 1a of the door frame body 1 and the door receiving surface 2a of the door stop 2. The hard mounting pieces 4a and 4b in the form of strips are formed in close contact with each other, and the hypotenuses are formed in the door contact packing 4c made of a soft material having a constant thickness.

The door abutment packing portion 4c is formed to have a tongue-shaped cross-section projecting from the tips of the hard mounting pieces 4a and 4b in opposite directions in the figure.
Although the tips of 4c and 4c are separated from each other, the structure may be such that they are continuously stretched between the tips of the hard mounting pieces 4a and 4b without separating them. The packing portion 4c is provided so as to project only on the tip end, and the packing portion 4c
The tip of the hard mounting piece may be close to or separated from the tip of the other hard mounting piece, in short, it may be continuous or discontinuous from the tip of the one hard mounting piece to the tip of the other hard mounting piece. You should just let it project.

Reference numeral 5 denotes a base end of the one hard mounting piece 4a which is brought into close contact with the inner surface 1a of the door frame body 1, and projects from the base end in an extending direction along the inner surface 1a of the door frame body 1. The protruding length of the hard fixing piece is equal to or slightly smaller than the depth of the groove 3 and the thickness thereof is smaller than the width of the groove 3. Further, the projecting end of the fixed piece 5 is integrally provided with a soft locking piece 6 which is bent in an obliquely folding direction toward the lower surface of the base end of the other hard mounting piece 4b. The portion 5 is elastically brought into close contact with and locked to the other groove side surface 3b of the groove 3.

In the packing material 4 as described above, the mounting pieces 4a and 4b and the fixed piece 5 made of hard PVC and the packing 4c and the locking piece 6 made of soft PVC are integrally formed by PVC extrusion molding. However, the structure is not limited to such a structure, and as shown in FIG. 5, the hard mounting pieces 4a and 4b and the packing portion 4c which are connected at right angles are formed separately. You may leave as a structure. That is, as the packing portion 4c, without adopting a tongue-shaped cross section as described above, a soft soft urethane or foamed polyethylene or the like whose surface is formed into a convex arc surface is used. It is also possible to use a rod-shaped member having elastic restoring force and integrally fix the packing portion 4c on the hard mounting piece portion 4b that is in close contact with the door receiving surface 2a of the door stop 2.

In order to attach the packing material 4 constructed as described above to the two door contact portions of the door frame body 1, one of the hard mounting piece portions 4a is brought into contact with the inner surface 1a of the door frame body 1. When the sliding door 2 is slid to the side, the fixing piece 5 protruding in the base end extension direction of the hard mounting piece 4a is inserted into the groove 3 and the other hard mounting piece 4b is pressed against the door. 2 door receiving surface

Not only is it possible to mount, but the hard mounting pieces 4a and 4b that are connected at right angles are fully adhered to the inner surface 1a of the door frame body 1 and the door receiving surface 2a of the door stop 2 respectively, and accuracy is improved. A good installation is possible.

In this attached state, the tip locking piece 6 of the fixed piece 5 inserted into the groove 3 is closely attached and locked to the groove side surface 3b of the groove 3 to prevent the packing material 4 from floating. However, as shown in FIG. 3, a part of the groove 3 is embedded inward from the surface 1a of the door frame body 1 and a part of its opening end is covered with the opening end face 1c of the fitting groove 1b. On the other hand, by making the locking piece 6 bend to the opposite side to the above structure, the tip of the locking piece 6 is locked to the opening end face 1c, and a reliable lifting prevention effect is achieved. You can Similarly, as shown in FIG. 4, the groove side surfaces of the groove 3 are inclined end surfaces 2b.
It is also possible to more securely prevent the rising by locking the locking piece portion 6 on the inclined end surface 2b by forming the above.

The locking piece 6 is not necessarily provided, and the thickness of the fixed piece 5 may be made equal to the groove width of the groove 3 for press fitting and fitting. An adhesive may be filled into the groove 3 to fix the fixed piece portion 5 in the groove 3 in an embedded state. Further, a receiving member (not shown) having a locking groove into which the tip of the fixed piece portion 5 is engaged may be embedded in the groove 3. Further, in order to fix the packing material 4 more firmly, the hard mounting piece 4b, which comes into close contact with the door receiving surface 2a of the door stop 2, may be adhered by using a double-sided adhesive tape or the like, as shown in the figure. It can also be fixed together by the tacker 7.

Next, an embodiment of the second aspect of the present invention will be described with reference to the drawings. Indicated at 1 is a door frame main body made of a rectangular plate member fixed to the inner peripheral surface of an entrance / exit opening in a room, and its inner surface 1a.
