Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to an interior door using extruded shapes of aluminum or aluminum alloy for the left and right stiles and the upper and lower stiles.

Prior Art The strength of this type of interior door is mainly maintained by the left and right vertical stiles and the upper and lower stiles, so in order to obtain the necessary strength, each stile is formed thickly, and its outer wall is wide and extends outward toward the outside. exposed. In addition, the doorway frame into which the door fits similarly needs to have sufficient strength, so the left and right vertical frames and upper and lower frames that make up the door frame are thick, and their outer walls are widely exposed to the outside. In this way, with conventional doors, the stile and the frame look wide to the outside, making them ungainly installed.Especially in architectural styles with elaborate interior and exterior designs, the installation condition and design of the door are often unsightly. The drawback was that it was difficult to unify the above.

Further, the door is sized to have a certain amount of clearance between it and the frame so that there is no problem in opening and closing the door. If this gap is constant when the door is closed, there will be no problem in terms of appearance, but with the conventional door installation structure, the door may tilt even slightly relative to the frame due to loose hinges, etc. As a result, the gap between the door and the frame expands in one direction, resulting in an unsightly installation.Even if the door maintains stability and there is no problem with opening and closing, the door may tilt more than necessary. There was also the problem that people were easily concerned about this.

Purpose of the invention This invention was devised in view of the above-mentioned actual conditions of conventional doors. The purpose is to prevent the door from being easily perceived even if the door is tilted.

Structure of the invention The structure of this invention to achieve the above-mentioned purpose is that, in an indoor entrance/exit opening/closing door in which the inner and outer panels are held by the left and right vertical frames and the upper and lower frames made of extruded shapes, the outer peripheral edge of the doorway frame is attached to the outside of the doorway. A flange is provided that covers at least part of the width of the front wall facing the door, and when the door is closed, the flange closes the gap between the door and the frame, and the front wall of the frame is closed. The width is made to appear narrower, and the flange is formed into an overlapping structure of an extension of the outer wall of the stile and an extension of the outer face plate, and the end is inverted and bent at the edge of the extension to hold the narrow face plate. The gist is that the stile is made to look as if it is narrow by forming a piece and using a face plate holding piece.

Embodiment The drawing shows an embodiment of this invention, in which a doorway E is opened between the hallway C and the room R, and an aluminum alloy frame F is fitted into the doorway E closer to the hallway C side. An interior door D, also made of aluminum alloy, is pivotally supported on the frame F so that it can be opened and closed.

At the entrance E, wooden boards 4 and 5 are provided at both left and right ends and at the upper end so that the frame F can stably receive the door D. Therefore, each of the wooden boards 4 and 5 is fixed to the pillar 1 and the lintel 2 while being slightly retracted from the corridor C side. Further, the wooden board 4 at one end and the wooden board 5 at the upper end are fixed to each other via an adjusting member 6.

The frame F consists of left and right vertical frames 11, 11 and upper and lower frames 12, 13 made of extruded shapes, respectively. It is assembled by screwing in the screws.

The left and right vertical frames 11, 11 and the upper frame 12 are the upper frame 1.
2 have the same cross-sectional shape except for having the screw pocket 14,
On the front wall 15 facing the corridor C side, both the inner and outer peripheral walls 16,
17 are arranged in series, and a mounting piece 18 is provided protruding from the center of the back surface.

The inner circumferential wall 16 is formed in such a length that its tip joins to the inner circumferential surface of the frame of the pillar 1 or the lintel 2, and has an L-shaped bent door stopper 19 connected to the wooden boards 4 and 5 at the tip. Door stopper 19 has door D.
A mounting groove 21 for the tight material 20 is formed to directly receive the material. On the other hand, the outer circumferential wall 17 is very short, and its tip is dimensioned to abut against the outer surface of the lath board 7. Further, the mounting piece 18 is formed in an L-shape, has a tip end sized to pass under the outer circumferential wall 17 and protrudes outward, and is nailed to the front surface of the pillar 1 or the lintel 2.

The lower frame 13 has an inverted U-shaped cross section having a front wall 22 and a rear wall 23, and has walls 2 on both the front and rear sides.
2 and 23 have sloped portions 22a and 23a at their upper ends (FIG. 2).

The lath board 7 is placed on top of the mounting piece 18 so as to press the tip of the attachment piece 18 against the pillar 1 or the lintel 2. A baseboard 8 is applied on top of the lath board 7, and a baseboard 8 is applied on top of the baseboard 8. A cross 9 is pasted on it.

Door D has left and right vertical stiles 31, 31 and upper and lower stiles 3.
In combination with 2, 33, the inner and outer double-sided plates 34, 3
5 is assembled as a flush door, and is sized to fit inside the frame F. Further, since a flange portion 36 covering a part of the front walls 15, 22 of the frame body F is provided on the front side peripheral edge thereof, the size of the flange portion 36 is enlarged.

Left and right stiles 31, 31 and upper and lower stiles 32, 33
have the same cross-sectional shape, and are invertedly bent toward the inner circumferential side at the outer circumferential edge of both side surfaces.
40 is formed, but the holding piece 40 on the hallway C side
A collar extension piece 38a is formed on the outer wall 38, and is provided at the end of the extension piece 38a. Therefore, among the inner and outer double-sided plates 34 and 35, the outer plate 35 is expanded in width by one size, and the end of the expanded part 35a is held down by the holding piece 40, and the flange part 36
has an overlapping structure of the extension piece 38a and the expansion part 35a.

Since the vertical frames 31, 31 of door D have the above-mentioned cross-sectional shape, the hinge 45 has a special structure in which both pieces 46, 47 are bent in a step-like manner (Fig. 3), and both pieces 46, 47 are bent in a stepped manner.
47 is passed through the vertical frame 11 and the vertical stile 31, and the tip portions 46a, 47a are fixed at respective predetermined locations with screws 48, 49.

Plywood is used for both the inside and outside panels 34, 35, and a cloth 42 made of the same fabric as the wall cloth 9 is pasted to the exterior board 35 facing the hallway C side.
In addition, the inner surface board 34 includes the pillar 1, the lintel 2, the wooden boards 4 and 5.
As if to match, the surface is formed as a wood-like decorative board. The face plate holding pieces 39, 40 formed on the frames 31, 32, 33 are attached to the face plates 34, 3.
It is exposed like an extremely narrow frame on the outer periphery of 5. However, the holding piece 39 on the indoor R side is
When the door D is closed, all but the one at the bottom of the door D are hidden behind the door stopper 19 of the frame F, and are completely invisible from the inside.

When opening and closing the above-mentioned door D, it is operated in the same way as a normal door, and when closed, it is received by the door stopper 19 of the frame F, and the tight material 20 of the door stopper 19 prevents ventilation between the door D and the frame F. is sealed in.

However, unlike conventional doors, when the door D is closed, the flange portion 36 covers approximately half of the front wall 15 of the frame F, making the width appear narrower, and the inner wall 16 of the frame F The gap 50 between them is hidden so that it cannot be seen at all, and furthermore, the gap 50 can be made larger than in the past. Therefore, when the door D is closed, the frame F and the frames 31, 32, 3
3 is hardly noticed, and since the front of door D is widely covered with cloth 42 made of the same fabric as wall cloth 9, it is so inconspicuous that it gives the illusion that door D is part of the wall. Become an existence.

Effects of the invention As explained above, according to this invention, a flange covering the outdoor front wall of the doorway frame is provided at the periphery of the door, and the flange is connected to the extension piece of the outer wall of the stile and the outer surface plate. The extension piece is formed in an overlapping structure with the extension part, and the edge of the extension piece is inverted and bent to form a narrow face plate holding piece, so when the door is closed, the stile and frame of the door can be seen from the outside side. Each frame looks narrow and sharp, giving it a very good appearance.Also, the gap between the door and the periphery of the frame is hidden from view from the outside by the flange, so even if the door is tilted, Even if the gap widens to one side, there is little risk of the inclination of the door becoming known, and in this respect as well, there is an excellent effect in that a good-looking door installation state can be obtained.
