[Conventional technology]

FIG. 2 shows the structure of a conventional door frame. 50 is the main frame, and the opening in the wall 51 It is fixed to the peripheral edge portion 51a. This main frame 50 has recesses 52 and 5 in the thickness direction of the wall 51. 2 is provided, and a recess 53 is also provided on the inner peripheral surface. 54 is a picture frame that also serves as wall thickness adjustment It is. This attached picture frame 54 is approximately U-shaped, and one end fits into the recess 52, and the other end is in the front. It is attached so as to be in contact with the outer surface of the marking wall 51. 55 is a door stop, which is a recess in the main frame 50. It is attached so as to fit into the section 53.

0003 The procedure for assembling this door frame is to glue the main frame 50 to the opening periphery 51a with adhesive. At the same time, a fastener 56 such as a wood screw is passed through the opening periphery 51a from the recess 53. It will stick. Next, attach the door stop 55 to the recess 53, and adjust the door 57 by hanging it. do. Then, a picture frame 54 is attached to the recess 52. At this time, a frame is attached according to the wall thickness. Adjust the length of one end or the other end of the edge 54 by cutting.

[Problem that the idea aims to solve]

In the conventional door frame, attached frames 54, 54 are attached to the front and rear of the main frame 50 as described above. Because it is a structure, there are many parts, which makes construction time-consuming and increases material costs. There was a problem. In addition, when adjusting the wall thickness, it is necessary to cut the attached picture frame 54, so it is easy to I couldn't work.

[0005] Therefore, the purpose of this invention is to reduce the number of parts and make construction easier. The purpose is to provide door frames.

[0006]

[Means to solve the problem]

The door frame of this invention is placed on one side of the periphery of the opening in the wall. an adjustment frame having a corner portion that abuts a corner portion of the opening; a corner portion that abuts the corner portion on the other side of the opening periphery, and a recessed portion is provided on the inner circumferential surface. At the same time, from this recess, the main frame fixed to the opening periphery with a fixing tool and the main frame fixed to the recess A fitting convex portion is provided on the outer circumferential surface and is also provided on the inner circumferential surface of the adjustment frame and the inner circumferential surface of the main frame. It is equipped with a doorstop arranged in such a way that the

[0007]

[Effect]

According to the structure of this invention, it is made up of three members: the adjustment frame, the main frame, and the door stop, so it has a large capacity. It is easy to construct and the material cost is low. Also, add corners to the main frame and adjustment frame. Since the corner portion is provided, the corner portion of the opening periphery of the wall fits well. When adjusting wall thickness, Adjust by moving the adjustment frame in the direction of wall thickness. The door stop originally rests against the edge of the door. In addition to this function, it also has the function of hiding the gap between the main frame and the adjustment frame and the fixing device.

[0008]

【Example】

A door frame according to an embodiment of this invention will be explained based on FIG. This door frame can be adjusted It includes a frame 1, a main frame 2, and a doorstop 3, and is disposed at the opening periphery 4a of the wall 4. concrete Specifically, the adjustment frame 1 is arranged on one side of the opening periphery 4a and It has a corner part 5 that comes into contact with a corner part on one side of a. In this case, the corner portion 5 is the opening periphery. At the side edge of one of the finishing materials 7a attached so as to sandwich the core material 6 placed in the section 4. come into contact with This adjustment frame 1 is fixed to a core member 6 with fasteners 8 such as wood screws. Also , the main frame 2 is disposed on the other side of the opening periphery 4a, and the main frame 2 is disposed on the other side of the opening periphery 4a. It has a corner part 9 that comes into contact with the corner part of. In this case, the corner part 9 is the other finishing material 7 abuts against the side edge of b. This main frame 2 is provided with a recess 10 on the inner peripheral surface and A fixing device 11 such as a wood screw is passed through the core material 6 through the recess 10 and fixed thereto. door The hit 3 has a protrusion 12 on its outer circumference that fits into the recess 10, and the inner circumference of the adjustment frame 1 and the main frame. It is arranged so as to straddle the inner circumferential surface of No. 2. 13 is a door.

[0009] Next, the procedure for assembling this door frame will be explained. First, the corner part 9 of the main frame 2 is Open the main frame 2 with the fixing tool 11 while it is in contact with the side edge of the other finishing material 7b. It is attached to the other side of the mouth periphery 4a. Next, move the adjustment frame 1 according to the thickness of the wall 4. Adjust the adjustment frame 1 so that the corner 5 comes into contact with the side edge of one of the finishing materials 7a. It is attached to one side of the opening periphery 4a using a fixing tool 8. Then, on the outer peripheral surface of door stop 3 Apply adhesive and fit the convex part 12 into the concave part 10 of the main frame 2 to attach the door stop. 3 is arranged so as to straddle the inner circumferential surface of the adjustment frame 1 and the inner circumferential surface of the main frame 2. In addition, adjustment Adhesive is also applied to the outer peripheral surfaces of the frame 1 and main frame 2 in advance.

0010 In this embodiment, in addition to the original function of the door stop 3 in contact with the edge of the door 13, The gap formed between the fairing frame 1 and the main frame 2 and the fixing tools 8 and 11 can be hidden. Ru.

[0011]

[Effect of the idea]

According to the door frame of this invention, it is composed of three parts: the adjustment frame, the main frame, and the door stop. It is easy to construct and the material cost is low. In addition, in the main frame and adjustment frame, Since the corner part is provided, the corner around the opening in the wall can be easily removed even if there is no attached frame like in the past. The parts fit together well. Also, when adjusting the wall thickness, move the adjustment frame in the direction of the wall thickness. Adjustments can be made by simply using the tool, and no cutting is required. The door stop is the original mechanism that touches the edge of the door. In addition to the function, it also has the function of hiding the gap between the main frame and the adjustment frame and the fixing device.
