The width w of the tongue pieces 8 and 13 is elastically deformed so that the tongue pieces 8 and 13 are fitted into the groove 5, so that the two adjacent frame components 1 are connected at right angles by the connecting plates 6 and 10.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a window frame assembly structure for a building window such as a skylight.

[0002]

[Prior art]

 In the conventional window frame, several window frame components are connected by screwing or welding, which not only takes a long time for the work but also has the drawback that the head of the screw and the bead of the welding are exposed and the appearance is not good. It was

[0003]

[Problems to be solved by the device]

 The problem to be solved by the present invention is to eliminate the above-mentioned drawbacks and to provide a structure which can be assembled very simply and aesthetically.

[0004]

[Means for Solving the Problems]

 As a means for solving the above problems, the present invention forms inwardly bent L-shaped cross-section ridges on the inner surface sides of both side edges of several frame constituent members constituting a polygonal window frame. A corresponding groove is formed, and elastic tongues are formed on both side edges of the bent connecting plate toward the bent portion of the connecting plate, and the tongue is bent to form the tongue from the back surface of the connecting plate. The height up to the tip of the groove is larger than the width of the groove, and the tongue piece is elastically deformed to fit into the groove so that two adjacent frame components are connected at right angles by the connecting plate. It was configured.

[0005]

[Operation and effect of the device]

 The present invention has the above-mentioned structure, and the two frame components adjacent to each other are connected at right angles by the connecting plate by elastically deforming the tongue piece and fitting the tongue piece into the groove, so that the assembling work is extremely easy. In addition, the head of the screw and the bead of welding are not exposed and it looks good.In addition, the tongue faces the bending part of the connecting plate and the tip is pressed against the inner surface of the groove. When the component and the connecting plate are pulled in the direction of separating, the tongue bites into the groove and becomes inseparable and is firmly connected.

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 is an aluminum frame component having an L-shaped cross section consisting of a vertical portion 2 and a horizontal portion 3, which are respectively provided on the inner surfaces of the side edges of both the vertical portion 2 and the horizontal portion 3. A ridge 4 having an L-shaped cross section is formed inward, and a groove 5 corresponding to each other is formed between the vertical portion 2 and the horizontal portion 3.

Reference numeral 6 denotes a first connecting plate for connecting the vertical portions 2 of the adjacent frame components 1 to each other on both side edges of the main body 7 formed by bending a steel plate at a bending portion 9 at a right angle, and on the bending portion 9 side. A plurality of elastically deformable tongues 8 are formed so as to project toward the outside and are bent obliquely toward the outside.

Reference numeral 10 denotes a second connecting plate that connects the horizontal portions 3 of the adjacent frame component members 1 to each other. A plurality of elastically deformable tongues 13 are formed, each projecting and bent obliquely downward.

The end portions of the adjacent frame component members 1 are cut at 45 degrees so that they are abutted at a right angle. As shown in FIG. 1, first, one frame component member 1 is divided into the first and second frame component members 1. Insert into one side of the connecting plates 6 and 10. Here, as shown in FIG. 2 (A), the height h from the back surface of the main body 7, 11 of the tongue pieces 8, 13 of the connecting plates 6, 10 to the tip of the tongue pieces 8, 13 is equal to that of the frame constituent member 1. Since the width w of the groove 5 is larger than the width w of the groove 5, the tongues 8 and 13 are elastically deformed and are inserted while being pressed against the inner wall of the groove 5 as shown in FIG. 2B. Even if it tries, the elastic force bites into the inner walls of the tongues 8 and 13 and they are irremovably connected.

Next, the other frame component 1 is inserted into the first and second connecting plates 6 and 10 in the same manner and connected.

In the present embodiment, since the frame component 1 is made of aluminum and the connecting plates 6, 10 are made of steel, the tongues 8 and 13 easily bite into the inner wall of the groove 5 and are firmly connected. You can
