Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to frame joining of a vertical frame and a horizontal frame of a corner portion of a window or door of a fitting.
Concerning a novel frame structure in which a diagonal tenon formed at the tip of a horizontal frame is fitted in a trapezoidal groove formed at the tip of the vertical frame, and the horizontal frame is fixed with screws or nails from the outside of the vertical frame Is.

[0002]

2. Description of the Related Art Conventionally, this type of frame corner joining method is
Widely used are those in which the vertical frame and the horizontal frame are directly nailed and fixed, or various joints in which the joints of the timber are cut into each other and combined. However, these methods are unsatisfactory in strength and poor in appearance only by the nailing of the former, and the latter joints have a drawback that they are not suitable for mass production because they are labor-intensive craftsmanship.

[0003]

SUMMARY OF THE INVENTION Therefore, according to the present invention, in joining a vertical frame and a horizontal frame at a corner portion of a frame such as a window, a trapezoidal cross section having a mechanically formed stopper at the tip of the vertical frame is formed. An object of the present invention is to provide a joining structure capable of mass production, in which a diagonal tenon machined at the tip of a horizontal frame is fitted into a groove and nailed.

[0004]

In order to achieve the above object, the joint structure of the corner portions of the window frame, door frame, etc. of the present invention has stoppers formed at the top and bottom ends of the vertical frame. Then, a groove with a frame width is formed with a trapezoidal cross section into which the inclined part of the diagonal tenon formed at the tip of the horizontal frame is fitted inside, and the diagonal tenon of the lateral frame is fitted into this trapezoidal groove to combine the vertical frame. This is a joint structure of the corners of window frames, door frames, etc., where the horizontal frame is fixed from the outside with nails or screws.

[0005]

The joining of the frame corners of the window frame, door frame, etc. constructed as described above is formed at the vertical wall of the stop formed at the tip of the vertical frame and at the tip of the horizontal frame. The inclined tenon at the end of the horizontal frame is fitted at a right angle into the groove of the trapezoidal cross section formed by the 45 ° inclined surface into which the inclined tenon of 45 ° is fitted, and the lateral side of the vertical frame is fixed by a nail or screw nail. Since the frame is fixed, it is possible to firmly join and fix it by groove fitting and nailing.

[0006]

EXAMPLES Examples will be described with reference to the drawings.
In FIG. 1, a stopper (2) is formed at the tip of the vertical frame (1) of the frame, and an inclined part of an oblique tenon (6) formed at the tip of the horizontal frame (5) is fitted inside this. The cross section of the vertical frame width forms a trapezoidal groove (3), and the slanted tenon (6) of the horizontal frame (5) is fitted into the trapezoidal groove (3) to combine the nails or nails from the outside of the vertical frame (1). The joint structure is formed by fixing the horizontal frame (5) with screw nails (8). In the drawing, long grooves (4) and (7) formed respectively on the left and right side surfaces of the vertical frame (1) and the horizontal frame (5) are grooves for mounting a frame material (9) for side surface decoration of the frame. .

[0007]

Since the present invention is constructed as described above, it has the following effects. When joining the corners of a frame such as a window, insert a diagonal tenon formed at the end of the horizontal frame into a groove with a trapezoidal vertical frame width where a stopper is formed at the end of the vertical frame. A sturdy fixing structure that is securely fixed from the outside of the vertical frame with nails or screw nails. Moreover, since the tip end portions of the vertical frame and the horizontal frame can be appropriately and quickly processed by a woodworking machine, there is a great advantage that accurate products can be mass-produced.
