Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a door frame mounting structure whose mounting width can be adjusted.

[Prior art]

The thickness of the frame K, such as a wall or pillar, to which the door frame is fixed is not always constant, and varies somewhat depending on the mounting location. The door frame has an adjustable mounting width and can be easily fixed in any location. As a width-adjustable door frame, a door frame installation structure has been developed in which a frame body with an L-shaped cross section is fitted inside, and the installation width is adjusted by adjusting the insertion depth of the fitting part. (Utility Model Publication No. 49-32424).

In this door frame, one frame body is provided with a U-shaped groove, and the leading edge of the other frame body is fitted into this U-shaped groove to connect them to each other. However, with this door frame mounting structure, the inner surface facing the outer circumferential surface of the closed door is not fixed to the frame, but only to both sides of the frame. Strength is required. Therefore, the outside of the U-shaped groove is reinforced with a doorstop, and the part that is inserted into this U-shaped groove is
It is reinforced by forming it into a double cylindrical shape. However, even with this structure, unless it is strongly reinforced, the door frame is likely to be deformed by the impact received when the door is closed, and the mounting position is also likely to shift. Furthermore, since the door frame becomes thicker, there is also a drawback that if the opening width of the frame is narrow, the width of the door to which it can be attached is restricted. Furthermore, since the double structure of the fitting insertion portion is not visible from the outside, although the structure of this portion is complicated and expensive, this does not appear on the outside and has the disadvantage of poor cost performance.

〔the purpose〕

The important purpose of this invention is that the door frame is divided into two parts, so it can be manufactured at low cost with a small number of parts.
Moreover, the divided frame can be easily and firmly fixed,
Furthermore, it is an object of the present invention to provide a door frame mounting structure in which the mounting width can be easily adjusted.

Another important object of this invention is to provide a door frame mounting structure that can substantially reduce the mounting thickness and allow a wide door to be mounted on a frame with a narrow door mounting width.

Furthermore, another important purpose of this invention is that the head of the fixing screw is hidden, and the fixing set screw that fixes the inside of the door frame does not require a special concealing member, and is easy to fit. To provide a mounting structure for a door frame which can prevent the door frame from slipping out, is beautiful, and can be firmly and securely fixed forever.

〔effect〕

The door frame mounting structure of this invention constructed as described above has the following features compared to conventional ones.

Although the door frame can be attached to frames of different thicknesses, the structure of the entire door frame is extremely simple, and it can be mass-produced at low cost, the door frame can be securely and firmly fixed to the frame for a long period of time.

This feature is due to the unique split structure of the doorstop frame and the fitting frame, so that the fixed piece of the split part is fixed to the main frame K, and the tip edge of the fitting frame that is inserted into the fitting groove is pressed. It has a plate shape that cannot be crushed, and
This is achieved by a structure in which the fixing piece is provided on the back side of the door stop. That is, according to this structure,
The door frame is fixed to the frame at three points, the middle and both sides where they fit together, and when the door stop receives a strong impact when the door is closed, the fixing piece is pressed against the sleeper and fixes it. The set screw is prevented from coming off, and the leading edge of the plate-shaped fitting frame is not crushed by impact, and the door frame is firmly fixed to the frame.

Even though the divided door frame is fixed to the frame at both the connecting parts and both sides, the screw heads are hidden, creating an extremely beautiful appearance.

In particular, the screws that fix the connecting part of the door frame to the frame do not require any special member to hide them, and are hidden by the fitting frame fitted into the fitting groove. The set screw, which is hidden by the tip of the fitted frame, is pushed into the frame K by the frame every time the door is closed, and
This prevents them from escaping. That is, when the door is closed and hits the door stop, the door stop pushes the fitting part of the fitting frame, which hits the head of the set screw of the fixing piece and pushes it into the frame K, thereby preventing the set screw from coming off.

Furthermore, since the head of the set screw of the fixing piece is hidden, it is not visible from the outside, and it also has the advantage that it can be easily driven into the frame K, although it is prevented from coming off. This feature has the advantage that the entire surface of the fixing piece is hidden by the fitting frame, so the fixing piece can be made longer to make it easier to screw onto the frame K. Moreover, the fitting frame hides the set screw even if it is separated from the back of the doorstop. This is because his head was pushed in.

In other words, the fixing piece provided at a unique position not only allows easy fixing, but also securely and firmly fixes the door frame, and also achieves the advantage of being beautifully finished without being visible on the outside.

The installation thickness of the door frame can be made thinner, allowing a wide door to be installed on a frame with a narrow door installation width. In other words, there are fewer restrictions on the width of doors that can be attached to the frame K, and more types of doors can be used.

This feature is realized by the structure in which the fitting portion of the fitting frame is thinned into a plate shape to increase the mounting strength, and the fixing pieces are fixed to the frame body K via sleepers. That is, by adjusting the thickness of the sleeper, the mounting thickness of the door frame can be adjusted significantly.

By simply screwing the mounting pieces of the inset frame, the door frame can be fixed without gaps according to the width of the mounting part, making it extremely easy to adjust the door frame width during installation. Furthermore, although the width can be adjusted, the number of parts is small, making it easy and inexpensive to manufacture.Furthermore, it can be installed after finishing the walls and interior, minimizing damage and scratches during work. Since it is easy to install, it also has the advantage that it can be installed by a do-it-yourselfer, even if you are not a professional engineer.
