However, the present invention relates to a technique for butt connection with high strength and good appearance.

BACKGROUND ART Conventionally, in a door frame structure, as shown in FIG. 6, the holding plates 1a, 1a formed on the vertical frame 1 are cut off over a length corresponding to the height of the horizontal frame 2, The end face of the horizontal frame 2 is brought into contact with the inner surface of the vertical frame 1 at the cut portion, and the tapping screw inserted into the through hole 7 of the vertical frame 1 is screwed into the tapping hole on the horizontal frame 2 side. 2 is connected, but at the connecting point, the vertical and horizontal frames 1 and 2 are simply butted, so this is conspicuous when there is a gap in the butted direction, and the horizontal frame 2 in the thickness direction There is a problem that the positioning is insufficient and a shift easily occurs in this direction. Further, there is a similar problem in the framed structure of the door in which the sandwiching plates facing each other are slanted in a taper shape so that the distance between them becomes narrower toward the front end side thereof to give a stereoscopic effect to the door.

[Object of the Invention] The present invention has been made in view of such problems,
The purpose is to increase the connection strength in the thickness direction without creating a gap in the abutting direction while tilting the holding plate for holding the door face plate to give a stereoscopic effect to the door. It is possible to provide a frame structure for a door that can improve the appearance by connecting diagonally sandwiching plates well.

Embodiments of the present invention will be described in detail below with reference to the drawings.

The door A is constructed by assembling the left and right vertical frames 1,1 and the upper and lower horizontal frames 2,2 into a square frame shape, and holding the peripheral portion of the door face plate 5 in such a square frame 10. There is. The vertical frame 1 and the horizontal frame 2 are respectively provided with a pair of sandwiching plates 1a, 1a; 2a, 2a facing the entire length in the frame length direction on the inner surface of each of the frame bodies mainly of a hollow rectangular pipe. . The vertical frame 1 and the horizontal frame 2 thus configured are extruded products made of aluminum and synthetic resin.

Although the vertical frame 1 and the horizontal frame 2 are butt-connected at substantially right angles to each other at their ends, the horizontal frame 2 on the side where the end faces in the frame length direction are butted against each other.
Further, an inserting recess 12 is formed by cutting on the outer surface of the holding plates 1a, 1a of the vertical frame 1 on the other side. The depth of the insertion recess 12 is deeper than the height of the holding plate 1a. And the insertion recess
The tips of the sandwiching plates 2a, 2a on the side where 12 is formed are cut at about 45 ° in the frame length direction. A clamping plate on the back of this cutting edge
An inclined surface 2d is formed such that the thickness of 2a becomes thinner toward the cutting edge 2c.

To follow. In such a case, the inclined surface 2d is in contact with the tapered surface 1b. afterwards,
The block 13 is inserted from the end of the vertical frame 1 and the tapping screw 9 as a connecting means, which is screwed into the block 13 in advance, is inserted into the through hole 7 formed in the vertical frame 1 and screwed with a tool such as a driver tool. The tapping screw 9 is advanced and screwed into the tapping hole 8 formed in the horizontal frame 2, and the horizontal frame 2 is strongly attracted to the vertical frame 1 side to make a strong connection. The block 13 shown in the figure has a pivot shaft 14 for rotating the door A. The pivot shaft 14 is formed by compressing a coil spring 16 inserted into the insertion hole 15 formed in the block 13. A retaining pin 18 inserted into the block 13 and a long hole 17 formed in the vertical frame 1 is screwed into the block 13 to allow the pivot shaft 14 to move up and down and to prevent the retaining.

In this way, the sandwiching plates 1a, 1a; 2a, 2a on the outer surface of the sandwiching plates 1a, 1a; 2
By forming the tapered surfaces 1b and 2b in which the distance becomes narrower toward the front end side of a and 2a, the door face plate 5 held between the sandwiching plates 1a and 1a; 2a and 2a is recessed from the frame surface to give a three-dimensional effect. An insertion recess 12 is formed on the horizontal frame 2 on the side where the end faces in the frame length direction are butted against each other. The insertion recess 12 is externally inserted on the outer surface of the vertical frame 1 holding plates 1a, 1a on the other side. By inserting 12 onto the clamping plates 1a, 1a, the vertical frame 1
And the horizontal frame 2 at the abutting point, the holding plates 1a, 1a are internally provided.
And there is no gap at the abutting position, and the insertion recess 12 is externally attached to the sandwiching plates 1a, 1a to position the vertical frame 1 and the horizontal frame 2 in the thickness direction, This increases the connection strength at the butting point. Moreover, the tip of the holding plate 2a, 2a on the side where the insertion recess 12 is formed, in the frame length direction is cut at about 45 °, and the thickness of the holding plate 2a is closer to the cutting edge 2c on the back of the cutting edge portion. By forming the thin inclined surface 2d, the cutting edge 2c is substantially aligned with the tapered surface 1b of the sandwiching plate 1a, and the appearance of the connecting portion is enhanced.

In the embodiment, the insertion recess 12 is formed in the horizontal frame 2, but the insertion recess 12 may be formed in the vertical frame 1.
Then, the insertion recess 12 is linearly performed with a cutting tool, and the machining of the inclined surface 2d is also performed all at once by such machining. The processing of the inclined surface 2d may be performed separately, and the inclination angle can be variously changed in design.

[Effects of the Invention] In summary, according to the present invention, by forming a taper surface on the outer surface of the sandwiching plate, the interval of which becomes narrower toward the tip end side of the sandwiching plate, the door face plate held between the sandwiching plates is recessed from the frame surface. While giving a three-dimensional effect, the horizontal frame or vertical frame on the side where the end faces in the frame length direction are abutted has an insertion recess that is externally inserted on the outer surface of the holding frame of the vertical frame or horizontal frame on the other side. Since it is formed and the insertion recess is externally attached to the sandwiching plate, the sandwiching plate exists inside the abutting position of the vertical frame and the horizontal frame, and no gap is created at the abutting position. Since the position of the holding plate is externally attached to the sandwiching plate, the vertical frame and the horizontal frame can be positioned in the thickness direction, the connection strength at the abutting point is enhanced, and the frame of the sandwiching plate on which the insertion recess is formed is formed. The tip in the length direction is omitted
