Description

The present invention relates to the construction of door openings.

Door openings provided indoors generally have a structure in which a frame member is attached to a wall, a door stop is provided on the frame member, and a door that opens and closes is arranged. The width of the door opening, which is the width of the door opening, should be large for the movement of wheelchairs and objects. In addition, since the frame material and the doorstop are exposed and are required to look beautiful, the frame material and the doorstop are often used in the same color as the door.

However, the exposed frame material may detract from the aesthetic appearance of the door opening. Therefore, in order to make the frame member invisible, Patent Document 1 discloses an invention in which the frame member is covered with a finishing material.

JP 2011-21459 A

However, in the invention disclosed in Patent Document 1, although the frame member is made invisible, a door stop is installed inside the door opening. Since the opening width of the door opening will be limited by the innermost door stop, the opening width of the door opening remains narrow.
Therefore, there has been a demand for a door opening structure that is excellent in appearance and has a large opening width.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a structure of a door opening that is excellent in appearance and has a wide opening width.

In order to achieve the above objects, the door opening structure according to the present invention is a door opening structure having a vertical frame formed in a wall, a door hinged to the vertical frame, and a finishing material. The door has projections on the opening side of the edges on the shaft side held by the hinge and on the opening/closing side, and the projections are formed on the shaft side and the opening/closing side of the door. The vertical frame has a protruding end surface and a stepped side surface on the closing side, the vertical frame has a first facing surface facing the end surface of the door and a second facing surface facing the stepped side surface, The finishing material is disposed on a surface facing the protruding end surface, and the protruding portion abuts against the second opposing surface when the door is closed, thereby preventing the door from moving too far toward the closing side. The vertical frame has no portion that protrudes toward the door opening from the first facing surface, including a door stop against which the closing side surface of the door abuts when the door is closed. The thickness from the second facing surface, which is the end surface on the opening side of the vertical frame, to the end surface on the closing side is the thickness from the surface on the opening side to the surface on the closing side of the door. Thinner than thick .

For example, in the structure of the door opening according to the present invention, the surface of the vertical frame is white.

For example, in the structure of the door opening according to the present invention, the surface of the vertical frame has the same color and pattern as the surface of the door.

For example, in the structure of the door opening according to the present invention, the door has a door body and an edge portion, the edge portion has the end surface, the protruding end surface and the stepped side surface, and the stepped side surface is provided with a cushioning material. are distributed.

According to the present invention, the vertical frame becomes difficult to see when the door is closed, so the appearance is excellent. Furthermore, since no doorstop is installed on the vertical frame, the opening width of the door opening is large.

First, the background of the problems to be solved by the present invention will be described.
The framed door, which is the structure of the door opening of the present invention, is installed at the doorway (opening) around the Western-style rooms and corridors of conventional wooden (frame construction method) buildings that account for about 70% of detached houses in Japan. for The large wall construction method (covering pillars with walls) is adopted for the opening. By the way, the traditional Japanese-style room was a straight wall construction method in which the pillars can be seen, but in recent years, the large wall construction method is often adopted in the Japanese-style room, and this case is also the object of the structure of the door opening of the present invention.

Originally, it is desirable for the width of the doorway to be as large as possible for users.
Assuming wheelchair care in an aging society, the government has promoted barrier-free measures to secure effective widths of 750 mm or more for entrances and exits of houses.

The door frame used in the frame construction method and the large wall construction method is three-dimensionally close to the pillars and the wall covering the installation part. For this reason, the maximum permissible width is guided by various restrictions such as the spacing and thickness of the pillars in the installed portion, the finished thickness of the wall, and the connection between the wall and the door frame.

The upper limit of the width of the doorway is obtained by subtracting the thickness of one pillar, the width of the vertical frame including the door stop, and the finished thickness of the buffer wall (see Fig. 8) from the pillar pitch of the installation opening. value.

As shown in the plan view of Fig. 4, the conventional construction method generally has a column pitch of 3 shaku (909 mm) and a column of 3.5 sun (105 mm). 12 mm), the effective width is 732 mm, and it is difficult to secure 750 mm. Therefore, it is difficult to realize barrier-free by avoiding troubles such as shifting the positions of the pillars.

In addition, in Japanese houses, it is overwhelmingly the case that the frame is installed so as to protrude from the wall at the openings provided at the inside corners on one side and both sides, and the actual situation is that the width is inevitably narrow.
For this reason, the door frames of each door manufacturer are very complicated and have a large number of module settings, and designers, suppliers, and builders are required to do complicated and difficult work, which is a heavy burden.

The combination of fittings and frames according to the present invention does not require a doorstop, and even when installed in an internal corner, the fitting frame can be directly attached to the pillar without receiving the cushioning of the wall.
Therefore, it is possible to supply a product that can easily secure a wider width than could be obtained by the conventional construction method without complicated considerations.

(Embodiment 1)
A structure of a door opening according to Embodiment 1 of the present invention will be described with reference to the drawings. As shown in the plan view of FIG. 1, the direction in which the door 20 is opened is the opening side, which is downward in FIG. The closing direction of the door 20 is the upper side in FIG. The direction in which the hinges are attached to the door 20 is the shaft side, which is the left side in FIG. The direction in which the door 20 is opened and closed is the opening/closing side, which is the right side in FIG.
In the structure of the door opening according to Embodiment 1 of the present invention, vertical frames 30 and 31 are attached to each of the two pillars 11 arranged inside the wall 10 so that the door opening faces each other. It is fixed between the upper part of the part and the floor surface. The vertical frame 30 and the vertical frame 31 have a rectangular cross-sectional shape, and the length of the wall 10 in the thickness direction is shorter than the length of the wall 10 of the pillar 11 in the thickness direction. The upper ends of the vertical frames 30 and 31 are positioned above the upper end of the door 20 , and the lower ends are positioned below the lower end of the door 20 . A door 20 is installed on the vertical frame 30 and the vertical frame 31 .

The standard values for the distance between the centers of the pillars 11, 11 are generally 3 shaku, 6 shaku, 9 shaku, and 12 shaku in the conventional framework construction method. In door openings, the distance between the centers of the pillars 11, 11 is overwhelmingly 3 shaku, or 909 mm. Furthermore, since the length of one side of the pillar 11 is generally 105 mm, the distance LP between the inner surfaces of the pillar 11 is 804 mm. Moreover, the thickness LB of the vertical frames 30 and 31 is generally 24 mm. Therefore, the length LA, which is the width of the opening, is 756 mm, which satisfies the barrier-free standard value.

The wall 10 has posts 11 , furring strips 12 , plasterboard 13 , facings 14 and baseboards 15 . The furrings 12 are partially arranged on the closed and open sides of the wall 10 where the posts 11 are absent and extend the surfaces of the closed and open sides of the posts 11 . The plasterboard 13 is arranged on the inner surface of the door opening of the pillar 11 and the closed and open side surfaces of the pillar 11 and the furring strip 12 without any gap except for the portion where the vertical frame 30 or the vertical frame 31 is fixed. .

A finishing material 14 is placed on the surface of the plasterboard 13 . A cloth material is generally used as the finishing material 14 . The finishing material 14 is folded at the corners of the plasterboard 13 and adhered continuously to the inner surface of the door opening and the closed and open sides of the wall 10 . The end face of the finishing material 14 is affixed against the side surface of the vertical frame 30 or the vertical frame 31, and the end face of the finishing material 14 is not exposed to the surface.

A skirting board 15 is arranged at the bottom of the wall 10 so as to be in contact with the floor. The baseboards 15 that intersect at the corners of the wall 10 are arranged with their obliquely cut faces abutting each other so that their surfaces and inner faces meet each other. The end surface of the baseboard 15 inside the door opening is placed against the side surface of the vertical frame 30 or vertical frame 31, so that it is not exposed to the surface.

The door 20 is opened by rotating to the opening side about the axis of the hinge 42.例文帳に追加The state shown in FIG. 1 is a state in which the door 20 is closed. The door 20 is fixed by a latch 40 to a latch receiver provided on the vertical frame 30 in a closed state.

The door 20 has a projecting portion 27 on the opening side of the opening/closing end, as shown in the enlarged plan view of FIG. The protruding portion 27 has a protruding end surface 21 on the opening/closing side and a stepped side surface 22 on the closing side. The door 20 has an end surface 23 on the opening/closing side excluding the protrusion 27 and a closing side surface 61 on the closing side of the door 20 .
The latch 40 is arranged on the end surface 23 and engages with a latch receiver provided in a recess provided on the inner surface of the door opening of the vertical frame 30 . The case lock 41 is arranged inside the door 20 .

When the door 20 is closed, the projecting end surface 21 is outside the surface of the vertical frame 30 inside the door opening. The stepped side surface 22 is located on the opening side of the vertical frame 30 on the opening side. The end surface 23 is located inside the surface of the vertical frame 30 inside the door opening. That is, when the door 20 is closed, the projecting portion 27 extends outside the surface of the vertical frame 30 inside the door opening. Thereby, when the door 20 is closed, the projecting portion 27 hides the gap between the end surface 23 and the inner surface of the vertical frame 30 when viewed from the opening side. Furthermore, when the door 20 is closed, the projecting portion 27 prevents the door 20 from moving too far toward the closing side and prevents light from leaking through the gap between the door 20 and the vertical frame 30 . A cushioning material may be arranged between the stepped side surface 22 and the open side surface of the vertical frame 30 .

The thickness LF of the door 20 is thicker than the thickness LG of the vertical frame 30 in the thickness direction of the door 20 . When the door 20 is closed, the closing side surface 62 of the vertical frame 30 is closer to the closing side than the closing side surface 61 of the door 20.例文帳に追加A step LE between the closing side surface 61 of the door 20 and the closing side surface 62 of the vertical frame 30 is set within 10 mm, preferably within 5 mm, for example, in order to improve the appearance when the door 20 is closed. It may be set. Moreover, the thickness LG may be larger than the thickness LF, and in that case the step LE may be larger than 10 mm.

The door 20 has a projecting portion 28 on the opening side of the axial end, as shown in plan view in FIG. The projecting portion 28 has a projecting end surface 25 on the outside of the door opening and a stepped side surface 24 on the closing side of the projecting portion 28 . The door 20 has an end face 26 on the shaft side excluding the protrusion 28 .
The hinge 42 has a door-side wing portion fixed to the end face 26 and a frame-side wing portion fixed to the inner surface of the door opening of the vertical frame 31 . In the present embodiment, the door 20 is held by the vertical frame 31 with the hinges 42, but instead of the hinges 42, the door 20 may be held by pivots.

When the door 20 is closed, the projecting end surface 25 is outside the surface of the vertical frame 31 inside the door opening. The stepped side surface 24 is located on the opening side relative to the opening side surface of the vertical frame 31 . The end surface 26 is located inside the inner surface of the door opening of the vertical frame 31 . That is, when the door 20 is closed, the projecting portion 28 extends outside the surface of the vertical frame 31 inside the door opening. Thereby, the protruding part 28 hides the gap between the end surface 26 and the inner surface of the vertical frame 31 when viewed from the opening side when the door 20 is closed. Furthermore, the projecting portion 28 prevents light from leaking through the gap between the door 20 and the vertical frame 31 when the door 20 is closed.

The thickness LF of the door 20 is thicker than the thickness LG of the vertical frame 31 in the thickness direction of the door 20 . When the door 20 is closed, the closing side surface 63 of the vertical frame 31 is closer to the closing side than the closing side surface 61 of the door 20 .
Although only the vertical frame has been described in the first embodiment, the horizontal frame placed above or below the door opening may also be configured so that the protruding portion of the door hides the gap between the door and the horizontal frame.

FIG. 5 shows a perspective view of the lower portion of the door opening arranged in this manner without the door 20 . A hatched area in the drawing represents the exposed surface of the vertical frame 31 . This hatched area is generally a different color or pattern than the finish 14 or skirting board 15, which is the color and pattern of the wood surface and has the same color and pattern as the door 20 surface. In addition, since finishing materials such as cloth generally have a white surface color, the surface color may be based on white, which is a similar color.

(Conventional structure 1)
Next, the structure of a conventional door opening will be described for comparison. As shown in FIG. 4, the direction in which the door 120 is opened is the opening side, which is downward in FIG. The direction in which the door 120 is closed, opposite to the opening side, is the closing side, which is the upper side in FIG. The hinge is attached to the door 120, and the direction in which the rotation axis of the door 120 lies is the shaft side, which is the left side in FIG. The direction in which the door 120 is opened and closed, which is opposite to the shaft side, is the opening/closing side, which is the right side in FIG.
In the structure of the door opening according to the conventional structure 1, as shown in plan in FIG. It is fixed between the top of the door opening and the floor so as to face it. The upper edges of the vertical frames 130 and 131 are above the upper edge of the door 120 , and the lower edges are below the lower edge of the door 120 . A door 120 is installed on the vertical frame 130 and the vertical frame 131 . Door stops 121 are arranged inside the door openings of the vertical frames 130 and 131, respectively.

The distance between the centers of the pillars 111, 111 is the same as in the first embodiment, which is 909 mm. Since the length of one side of the column is also 105 mm, the distance LP between the inner surfaces of the columns 111 is 804 mm, which is the same as in the first embodiment. Moreover, the thickness of the vertical frame 130 and the vertical frame 131 is 24 mm as in the first embodiment. The thickness of each projection of the door stop 121 is 12 mm. Therefore, the length LC, which is the opening width (effective width), is 732 mm, which does not satisfy the barrier-free standard.

The vertical frame 130 and the vertical frame 131 have a rectangular cross section, the length in the thickness direction of the wall 110 is longer than the thickness of the wall 110, and protrudes from the surfaces of the wall 110 on the closing side and the opening side. The vertical frame 130 and the vertical frame 131 are fixed by screws between the upper part of the door opening and the floor so as to face each other on the inner surface of the door opening of the two pillars 111 inside the wall 110. It is

Wall 110 has posts 111 , furring strips 112 , plasterboard 113 , finishes 114 and baseboards 115 . The furring strips 112 are partially arranged on the closed side and the open side without the pillars 111 so as to extend the surface of the pillars 111 . The plasterboards 113 are arranged on the closed side and the open side of the pillar 111 and the furring strip 112 without gaps.

A finishing material 114 is applied to the outside of the plasterboard 113 . The end face of the finishing material 114 is affixed against the side surface of the projecting portion of the vertical frame 130 or vertical frame 131 and is not exposed to the surface.

A skirting board 115 is arranged at the bottom of the wall 110 so as to be in contact with the floor. The end face of the baseboard 115 is placed against the side surface of the projecting portion of the vertical frame 130 or the vertical frame 131 and is not exposed to the surface.

The door 120 rotates to the opening side about the axis of the hinge 142 and opens. The state shown in FIG. 4 is a state in which the door 120 is closed. A latch 140 arranged at the end of the door 120 on the opening/closing side is fitted and fixed to a latch receiver provided on the vertical frame 130 when the door 120 is closed. The hinge 142 has a door-side wing portion fixed to the shaft-side end portion of the door 120 , and a frame-side wing portion fixed to the surface of the vertical frame 131 inside the door opening.

The door stop 121 is fixed to the surfaces of the vertical frames 130 and 131 on the inner side of the door opening at a position where the closing side surface of the end portion of the door 120 abuts when the door 120 is closed. A cushioning material may be provided between the door stop 121 and the door 120. FIG. The presence of the doorstop 121 prevents the door 120 from rotating excessively toward the closing side when the door 120 is closed, and prevents light from leaking through the gap between the door 120 and the vertical frame 130 and the vertical frame 131. To prevent.

FIG. 6 shows a perspective view of the lower portion of the door opening arranged in this manner without the door 120 . The hatched areas in the figure represent the exposed surfaces of the vertical frame 131 and the doorstop 121 . This hatched area is generally a different color or pattern than the finish 114 or skirting board 115 , which is the color and pattern of the wood surface and has the same color and pattern as the surface of the door 120 .

(Comparison between Embodiment 1 and Conventional Structure 1)
Embodiment 1 and conventional structure 1 will be compared and explained.
A jamb is used to hold the door in the construction of the door opening. The vertical frame must have a certain thickness because it must be strong enough to support the weight of the door and also deep enough to form a recess for fitting the latch. However, there is also a condition that the thinner the door opening, the better, because the greater the opening width of the door opening, the higher the convenience. Therefore, the thickness of the vertical frame is usually the minimum necessary thickness.

It is assumed that the thicknesses of the vertical frames 30 and 31 of Embodiment 1 and the vertical frames 130 and 131 of the conventional structure 1 are the same thickness. In the conventional structure 1, it is necessary to arrange the door stop 121, but in Embodiment 1 of the present invention, it is not necessary to arrange the door stop. As a result, the opening width LA shown in FIG. 1 can be made larger than the opening width LC shown in FIG. 3 even if the distance between the pillars is the same and the thickness of the vertical frame is the same.

In the conventional structure 1, the ends of the vertical frame 130 and the vertical frame 131 protrude from the wall 110 because it is convenient for the end face treatment of the finishing material 114 and the baseboard 115. This is because the end surfaces of the timber 114 and the baseboard 115 are exposed, which spoils the appearance. Therefore, since the end surfaces of the finishing material 114 and the baseboard 115 are not exposed, the appearance is not spoiled.
Further, in Embodiment 1, the finishing material 14 is bent at the corners of the wall 10, and the baseboards 15 have their surfaces butted together at the corners of the wall 10, and the end faces are not exposed. Furthermore, since the finishing material 14 and the baseboard 15 are in contact with the side surfaces of the vertical frame 30 and the vertical frame 31, the end surfaces of the finishing material 14 and the baseboard 15 are not exposed. Therefore, the first embodiment also does not impair the aesthetic appearance. That is, in this respect, the first embodiment and the conventional structure 1 are comparable.

In the conventional structure 1, when the door opening is viewed from the opening side with the door 120 closed, the door stop 121 is behind the gap between the door 120 and the vertical frames 130 and 131. and the vertical frame 130 and the vertical frame 131 do not leak light.
In the first embodiment, when the door opening is viewed from the opening side with the door 20 closed, the vertical frame 30 and the vertical frame 31 are located behind the gap between the door 20 and the finishing material 14. Light does not leak through the gaps between the door 20 and the vertical frames 30 and 31. - 特許庁That is, in this respect, the first embodiment and the conventional structure 1 are comparable.

In conventional structure 1, when the door 120 is closed and the door opening is viewed from the open side, thick vertical frames 130 and 131 can be seen around the door 120. - 特許庁The ends of the vertical frame 130 and the vertical frame 131 protrude from the surface of the wall 110 so that the end surfaces of the finishing material 114 and the baseboard 115 are brought into contact with each other. Therefore, the presence of the vertical frame 130 and the vertical frame 131 is large, and it cannot be said that the appearance is excellent. Also, in order to improve the appearance, a vertical frame having the same color and pattern as the color and pattern of the surface of the door 120 is generally used. Furthermore, the length of the vertical frame 130 and the wall 110 of the vertical frame 131 in the thickness direction varies according to the combination of the size of the pillar 111, the thickness of the plasterboard 113, the thickness of the finishing material 114 and the thickness of the baseboard 115. Is required. Therefore, it is necessary to stock materials for the vertical frames according to the type of door surface, wall thickness, etc., which increases the burden of inventory costs.

In Embodiment 1, when the door opening is viewed from the opening side with the door 20 closed, the vertical frame with a large presence unlike the conventional structure 1 is not visible around the door 20, and the appearance is beautiful. Excellent for A vertical frame 30 and a vertical frame 31 are located at the back of the gap between the door 20 and the finishing material 14, but they are not conspicuous because they are at a recessed position. Therefore, it is not necessary to make the surface color and pattern of the vertical frames 30 and 31 the same as the surface color and pattern of the door 20 . In addition, since the length of the wall 10 in the thickness direction of the vertical frame 30 and the vertical frame 31 is not affected by the thickness of the wall, there is no need to keep many types of inventory according to the thickness of the wall. will reduce the burden on Moreover, most of the wallpapers generally used as the finishing material 14 have a white base tone. Therefore, by making the surfaces of the vertical frame 30 and the vertical frame 31 the same color based on white, it is possible to make them even less conspicuous.

Further, in the conventional structure 1, when the door opening is viewed with the door 120 open, the vertical frame 131 having a surface different from that of the finishing material 114 is conspicuous as shown in FIG. do not have.
In Embodiment 1, when looking at the door opening with the door 20 open, the vertical frame 31 having a surface different from that of the finishing material 14 is less noticeable as shown in FIG. Furthermore, if the surface of the vertical frame 31 has the same base color as the wallpaper, it becomes less conspicuous and is more aesthetically pleasing.

(Embodiment 2)
A structure of a door opening according to Embodiment 2 of the present invention will be described with reference to the drawings. In the structure of the door opening according to Embodiment 2 of the present invention, two door openings are arranged orthogonally adjacent to each other, as shown in plan view in FIG.

The vertical frame 330, vertical frame 331 and door 320 of the door opening shown in the lower part of FIG. Since the length of the vertical frame 330 and the vertical frame 331 in the wall direction is longer than the thickness of the wall, they interfere with each other and cannot be attached to the two orthogonal surfaces of the pillar 311 . Therefore, it is necessary to separate the vertical frame 330 and the vertical frame 331 from the pillar 311 and fix them so that they do not interfere with each other.

A vertical frame 330 of the door opening shown in the lower part of FIG. 8 is fixed to the lower side surface of the column 311 in FIG. 8 with screws 351 with spacers interposed therebetween. A vertical frame 331 is fixed at a position facing the vertical frame 330 , and a door 320 is installed on the vertical frame 330 and the vertical frame 331 . Therefore, the vertical frame 330 is fixed at a position farther from the pillar 311 than in the door opening structure according to the conventional structure 1 .

Another door opening vertical frame 331 is fixed to the right side surface of the column 311 in FIG. A vertical frame (not shown) is fixed at a position facing the vertical frame 331, and the door 321 is installed on the vertical frame 331 and the vertical frame (not shown). Therefore, the vertical frame 331 is fixed at a position farther from the pillar 311 than in the door opening structure according to the conventional structure 1 .

As with conventional structure 1 , wall 410 has posts 411 , furring strips 412 and plasterboard 413 . In the conventional structure 3, illustration of finishing materials and skirting boards is omitted. The plasterboard 413 is placed on the closing face and only on the closing face, as in conventional structure 1 . Then, the end surface of the plasterboard 413 is not hidden by the vertical frame 430. - 特許庁Therefore, the casing material 450 and the casing material 451 are arranged. The casing material 451 has an L-shaped cross section. By inserting one end of the casing material 450 or casing material 451 into one of the slits of the vertical frame 430 and placing the other end in contact with the plasterboard 413, the end face of the plasterboard becomes invisible.

Next, the portion of the structure of the door openings of the conventional structure 3, shown in the upper part of FIG. 9, where two door openings are arranged orthogonally adjacent to each other will be described. One end of the casing material 450 and casing material 451 is inserted into one of the slits of the vertical frame 430, and the other end is placed in contact with the plasterboard 413. Therefore, the positional relationship with the plasterboard 413 is In order to ensure the vertical frame 430 cannot be placed directly on the column 411, it must be separated.

The vertical frame 430 is fixed to the right side surface of the column 411 with a spacer 416 interposed therebetween. A vertical frame (not shown) is fixed at a position facing the vertical frame 430, and the door 420 is installed on the vertical frame.
Another vertical frame 430 is fixed to the lower side surface of the column 411 with a spacer 416 interposed therebetween. The walls are provided with furring strips 412 and plasterboards 413 as in conventional structure 1 . One of the casing material 450 , the casing material 451 and the casing material 452 is inserted into one of the slits of the vertical frame 430 and the other is placed in contact with the plasterboard 413 .

The door 420 is installed on a vertical frame 430 and is provided with hinges and latches (not shown). The doorstop 421 is arranged on the vertical frame 430 at a position on the closing side of the closed door 420 .

(Comparison between Embodiment 2 and Conventional Structure 2)
Embodiment 2 of the present invention and conventional structure 2 will be compared and explained.
In Embodiment 2, the length of the vertical frame 230 and the vertical frame 231 in the thickness direction of the door 220 and the door 221 is shorter than the length of the pillar 211 in the thickness direction of the door 220 and the door 221 . Therefore, the vertical frames 230 and 231 can be arranged on the two orthogonal surfaces of the column 211 as they are. Therefore, the opening width LA is the same length as in the first embodiment, satisfying the barrier-free standard.

However, in conventional structure 2, the lengths of the vertical frames 330 and 331 in the thickness direction of the doors 320 and 321 are longer than the lengths of the pillars 311 in the thickness direction of the doors 320 and 321 . For this reason, it is not possible to attach them to two sides of the wall as they are as in the second embodiment because they interfere with each other. Therefore, either door opening must be spaced from the pillar to avoid interference and spacers 316 must be provided to fill the gap.

Therefore, in conventional structure 2, the length of the opening width of the door opening becomes shorter than that of conventional structure 2 by the amount of separation of the vertical frame 330 from the pillar 311, and does not satisfy the barrier-free standard. Further, in order to separate the vertical frame 330 from the pillar, more members than in the second embodiment are required, increasing the material cost and man-hours.

(Comparison between Embodiment 2 and Conventional Structure 3)
In the conventional structure 3, slits are provided in the vertical frames 430 and 431, and the casing material 450 and the casing material 451 are arranged to hide the joint with the wall 410. Therefore, in order to separate the vertical frame from the pillar 411 A spacer 416 is required. Furthermore, when it is attached to two sides of a wall, it cannot be attached as it is because the casing materials interfere with each other. Therefore, a spacer 416 for fixing the casing material 451 and an additional casing material 452 are required. Therefore, the length of the opening width is shorter than that of the second embodiment.

Therefore, in conventional structure 3, the opening width of the door opening is narrowed by the distance between the vertical frame 430 and the vertical frame 431 from the column 411 . Furthermore, in order to hide the adjacent portion, more members than in the second embodiment are required, increasing material costs and man-hours.

(Embodiment 3)
A third embodiment of the present invention will be described with reference to the drawings. In the third embodiment, the protruding portion 527 formed on the door 520 is made of a material different from that of the main body of the door 520 . Only the door differs from the first embodiment.

As shown in FIG. 10, the main body of the door 520 does not have a protrusion like the door of the conventional structure 1 . Edge portions 570 having a substantially L-shaped cross section and the same longitudinal length as the door 520 body in the vertical direction are fixed to both ends of the door 520 body to form the door 520 . The edge portion 570 is formed by extruding aluminum, for example, but it may be formed by molding resin. The length in the thickness direction of door 520 of the portion of edge portion 570 that contacts the end surface of the door body is the same as the thickness of door 520 body. The shape of the protruding portion 527 of the edge portion 570 is the same as that of the protruding portion 27 according to the first embodiment. The projecting portion 527 has a projecting end surface 521 on the outside of the door opening and a stepped side surface 522 on the closing side. Edge portion 570 has end face 523 outside the door opening except for protrusion 527 . When the door 520 is closed, the protruding end surface 521 is outside the surface of the vertical frame 530 inside the door opening. Further, the step side surface 522 is located on the opening side rather than the closing side surface of the vertical frame 530 . Further, the end surface 523 is located inside the surface of the vertical frame 530 inside the door opening. That is, the projecting portion 527 extends outside the surface of the vertical frame 530 inside the door opening.

The projecting portion 527 is hollow, and a slit is formed over the entire length of the stepped side surface 522 in the middle in the left-right direction. A tight material 580, which is a cushioning material, is arranged in a portion that abuts against the vertical frame 530 when the door 520 is closed. The tight member 580 has an attachment portion that fits into the cavity of the slit and the projecting portion 527, and an abutting portion that bends to abut against the vertical frame 530 when the door 520 is closed. 522 attached. The tight material 580 is an elastic member, and is made of rubber, for example.
As a cushioning material, a foam member having a rectangular or semicircular cross section or an elastic member such as rubber may be attached to the side surface 522 of the step so that it partially contacts the vertical frame 530 when the door 520 is closed. good.

Although FIG. 10 shows only the opening/closing side of the door opening, the edge portion 570 is fixed to the main body of the door 520 similarly on the shaft side.
Although only the vertical frame has been described in the third embodiment, the horizontal frame arranged above or below the door opening may have the same configuration.

According to Embodiment 3 of the present invention, the door 520 main body does not need to be provided with a projecting portion as in the conventional structure, so that the processing cost of the door 520 main body can be reduced. In addition, since the both side edges of the door 520 are covered with metal, when the hinges and latches are fixed to the door, they can be fixed more firmly than the wood surface.

The present invention is capable of various embodiments and modifications without departing from the broader spirit and scope of the invention. The above-described embodiments are intended to illustrate the invention and do not limit the scope of the invention.
