Abstract

PURPOSE:To fit diagonal tenons formed on the front ends of the top and bottom rails in grooves having a trapezoid section formed on the front ends of the stiles and to obtain joining construction of frame corner sections formed by fixing the top and bottom rails with screws or nails from the outsides of the stiles in the case frame joining of the stiles with the top and bottom rails of the corner sections in the frame of a window, door, etc., of fittings. CONSTITUTION:In a framing 1 such as a window frame, door frame, etc., inclinations of diagonal tenons 6 formed on the front ends of the top and bottom rails 5 are fitted in grooves 3 having a trapezoid section with a frame width formed to the insides of stoppers 2 formed on the front ends of both upper and lower ends of each of the stiles. The diagonal tenons on the front ends of the top bottom rails are fitted in the trapezoid grooves in a right closely in a right angle, and the top and bottom rails are fixed with nails or screws from the outsides of the stiles.

Description

[Detailed description of the invention]

0001

[Industrial Field of Application] This invention relates to the frame joining of vertical frames and horizontal frames at corners of frames for windows, doors, etc. of fittings.
This relates to a new framework structure in which a diagonal tenon formed at the tip of the horizontal frame is fitted into a groove with a trapezoidal cross section formed at the tip of the vertical frame, and the horizontal frame is fixed from the outside of the vertical frame with screws or nails. It is.

0002

[Prior Art] Conventionally, this type of frame corner joining method was as follows:
Various types of joints are widely used, such as directly nailing the vertical frame and horizontal frame together, or making cuts in the joints of the wood joints. However, these methods have the drawback that the former method, which involves only nailing, is unstable and looks bad, while the latter method, which uses joints, requires a lot of work and is similar to that of a joiner, making it unsuitable for mass production.

0003

[Problems to be Solved by the Invention] Therefore, the present invention provides a trapezoidal cross section with a machine-formed stop portion formed at the tip of the vertical frame in joining a vertical frame and a horizontal frame at the corner of a frame such as a window. The object of the present invention is to provide a joint structure that can be mass-produced and is formed by fitting a diagonal tenon machine-formed at the tip of a horizontal frame into the groove and nailing it.

0004

[Means for Solving the Problems] In order to achieve the above object, the joint structure of the corner portions of window frames, door frames, etc. of the present invention is such that stop portions are formed at the tips of both the upper and lower ends of the vertical frame. Then, on the inside of this frame, a groove with a trapezoidal cross section and the width of the frame is formed into which the sloped part of the diagonal tenon formed at the tip of the horizontal frame is inserted, and the diagonal tenon of the horizontal frame is inserted into this trapezoidal groove and assembled, and the vertical frame is assembled. This is a joint structure for the corners of window frames, door frames, etc., in which the horizontal frame is fixed from the outside with nails or screws.

[0005]

[Function] The corner portion of the window frame, door frame, etc. configured as described above is connected to the vertical wall of the stop formed at the tip of the vertical frame and the vertical wall of the stop formed at the tip of the horizontal frame. Insert the inclined tenon at the tip of the horizontal frame at right angles without any gaps into the groove with a trapezoidal cross section formed by the 45° slope into which the 45° inclined tenon is inserted, and then insert the horizontal frame with a nail or screw from the outside of the vertical frame. Since the frame is fixed, firm connection and fixation can be achieved by groove fitting and nailing.

[0006]

[Example] An example will be explained with reference to the drawings.
In Figure 1, the end of the vertical frame (1) of the framework has a stopper (
2), and a trapezoidal groove (3) with a cross section of the width of the vertical frame into which the inclined part of the diagonal tenon (6) formed at the tip of the horizontal frame (5) is inserted is formed inside the groove (3). A joint structure in which the diagonal tenon (6) of the horizontal frame (5) is inserted into the groove (3) and assembled, and the horizontal frame (5) is fixed from the outside of the vertical frame (1) with nails or screws (8). It is. In addition, in the drawing, vertical frame (1) and horizontal frame (5)
Long grooves (4) and (7) formed on the left and right sides of the
is a groove for attaching a frame material (9) for side decoration of the frame.

[0007]

[Effects of the Invention] Since the present invention is constructed as described above, it produces the effects as described below. When joining the corners of frames such as windows and doors, a diagonal tenon formed at the tip of the horizontal frame is inserted into a groove with a trapezoidal cross section the width of the vertical frame, in which a stopper is formed at the tip of the vertical frame. It has a sturdy fixed structure that is securely fixed from the outside of the vertical frame with nails or screws. Moreover, since the tips of the vertical and horizontal frames can be processed appropriately and quickly using a woodworking machine, there is a great advantage that accurate products can be mass-produced.

Claims (1)

[Claims] Claim 1: When joining a vertical frame and a horizontal frame at a corner of a window frame, door frame, etc., a stopper is formed at the top and bottom ends of the vertical frame, and a stopper part is formed at the tip of the vertical frame. The cross section of the vertical frame width into which the slope of the diagonal tenon formed at the tip is inserted forms a trapezoidal groove,
The frame corner joint structure is formed by fitting the diagonal tenon of the horizontal frame into this trapezoidal groove and assembling the horizontal frame, and fixing the horizontal frame from the outside of the vertical frame with nails or screws.
