Description

The present invention relates to fittings provided with mullions.

Patent Literature 1 discloses a configuration including a meeting frame and a meeting mullion of a sliding door with a single sliding structure.

Japanese Patent No. 6386360 Japanese Patent No. 6431327

The fitting of Patent Document 1 is provided with a concave portion facing the inside of the frame on the outdoor facing surface of the mullion. This type of recess generally functions as a retracting space for the door frame and handle when the sliding door is opened. However, in the configuration of Patent Literature 1, the frame inner opening of the recess is closed with the shape member. It is believed that this is because the concave portion is hidden by the resin shaped member to prevent the metal member from being exposed to the inside of the room, thereby ensuring heat insulating performance and appearance quality. However, in this configuration, the recess blocked by the profile cannot be utilized as a retraction space, resulting in a reduction in the amount of opening of the sliding door.

On the other hand, Patent Literature 2 discloses fittings in which a door body is provided with a window for ventilation (ventilation unit). In fittings of this type, since the ventilation unit is arranged inside the sliding door, the vertical frame of the ventilation unit is also arranged in addition to the meeting frame of the sliding door on the outdoor side of the mullion. For this reason, this type of fittings tends to have more metal members exposed to the indoor side near the mullions than fittings that are not for ventilation. It is even more difficult to achieve both quality improvement.

As shown in FIG. 1 , a fitting 10 according to one embodiment includes an opening frame 12 fixed to an opening formed in a building frame, and a door body 14 slidably supported by the opening frame 12 . The fitting 10 is used, for example, as an entrance door.

In the present application, the prospective direction refers to the depth direction of the fitting 10 (the direction indicated by the arrow Z in the drawing), and the prospective surface refers to a surface extending along the prospective direction. The viewing direction is a direction perpendicular to the projection direction, and in the case of a vertical frame 12c or the like that is elongated in the vertical direction, the horizontal direction (the direction indicated by the arrow X in the figure) perpendicular to the longitudinal direction. In the case of a long upper frame 12a or the like, the vertical direction (the direction indicated by the arrow Y in the drawing) perpendicular to the longitudinal direction thereof. A facing surface is a surface along the facing direction. The inside of the frame refers to the inner portion of the opening frame 12 or the like, which is a frame-shaped member. The frame outside refers to the outer peripheral portion of the opening frame 12, which is a frame-shaped member, fixed to the building skeleton. The in-frame direction refers to a direction from the outside of the frame such as the opening frame 12, which is a frame-shaped member, toward the inside of the frame. The frame-outside direction refers to a direction from the inside of the frame such as the opening frame 12, which is a frame-like member, toward the outside of the frame.

As shown in FIGS. 1 to 3, the opening frame 12 is made up of an upper frame 12a, a lower frame 12b, a vertical frame 12c, and a mullion 12d. Each frame 12a-12c is an extruded shape such as an aluminum alloy. Attachment members 16 made of resin such as vinyl chloride resin (PVC) are attached to the interior side portions of the frame inner projection surfaces of the frames 12a to 12c.

The mullion 12d is an extruded shape member such as an aluminum alloy, and a resin-made mullion attachment member 17 made of PVC or the like is attached to a part of the mullion 12d. 12 d of mullions have the chamfered part 20 formed so that the corner|angular part of the outdoor side of the frame inner projection surface 12d1 was notched. The chamfered portion 20 forms a retracting space for the door frame 22c of the door body 14 and the pull part 60 attached thereto. The chamfered portion 20 of the present embodiment is, for example, a recess obtained by notching a corner portion at a right angle. The mullion attachment member 17 has a substantially crank-shaped cross section, and covers the frame inner projection surface 12d1 and the inner surfaces 20a and 20b of the chamfered portion 20. As shown in FIG.

As shown in FIGS. 1 to 3, the door body 14 is a single sliding door that is supported by the opening frame 12 and slides inside the frame in the X direction. The door body 14 has a ventilation unit 21 and a frame body 22 .

First, the frame body 22 is formed by assembling an upper frame 22a, a lower frame 22b, a door frame 22c, and a meeting frame 22d. The frame 22 has a composite structure in which a metal frame 23 made of an extruded shape such as an aluminum alloy and a resin frame 24 made of an extruded shape such as PVC are combined. The metal frame material 23 has a metal upper frame 23a, a metal lower frame 23b, a metal door frame 23c, and a metal combination frame 23d. The resin frame material 24 has a resin upper frame 24a, a resin lower frame 24b, and a resin door frame 24c.

The upper frame 22a is formed by attaching a resin upper frame 24a to the interior facing surface of the metal upper frame 23a. The lower stile 22b is obtained by mounting a resin lower stile 24b on the interior facing surface of the metal lower stile 23b. The door frame 22c is obtained by attaching a resin door frame 24c to the interior facing surface of the metal door frame 23c. The meeting frame 22d is composed of a metal meeting frame 23d.

As shown in FIG. 2, in the door body 14, a guide 25 provided on the frame outer projection surface of the upper frame 22a is guided by the rail 26a of the upper frame 12a, and a door roller 27 provided on the frame outer projection surface of the lower frame 22b is guided. It slides by rolling on the rails 26b of the lower frame 12b.

Next, as shown in FIGS. 2 and 3, the ventilation unit 21 is a ventilation window for allowing air to circulate indoors and outdoors with the door 14 closed. In this embodiment, the ventilating unit 21 is exemplified by a sliding window. The ventilation unit 21 has a ventilation opening frame 28 , an outer shoji 29 and an inner shoji 30 , and a screen device 31 .

The ventilation opening frame 28 is formed by framing an upper frame 28a, a lower frame 28b, and left and right vertical frames 28c and 28d. The ventilation opening frame 28 has a composite structure in which a metal frame member 33 made of an extruded shape such as an aluminum alloy and a resin frame member 34 made of an extruded shape such as PVC are combined. The metal frame member 33 has a metal upper frame 33a, a metal lower frame 33b, and metal vertical frames 33c and 33d. The resin frame member 34 has an upper resin frame 34a, a lower resin frame 34b, and vertical resin frames 34c and 34d.

The upper frame 28a is formed by attaching a resin upper frame 34a to the frame-inside prospective surface of the metal upper frame 33a. The lower frame 28b is obtained by attaching a resin lower frame 34b to the frame-inside prospective surface and the room-interior facing surface of the metal lower frame 33b. The vertical frames 28c and 28d are obtained by attaching resin vertical frames 34c and 34d to the frame inner projection surface and the room interior facing surface of the metal vertical frames 33c and 33d, respectively.

Opening grooves 35a and 35b aligned in the direction of projection are provided on the inside projection surfaces of the vertical frames 28c and 28d, respectively. The ventilation unit 21 of this embodiment includes two shojis 29 and 30 arranged in the indoor-outdoor direction. The side ends of the shojis 29, 30 are inserted into the opening grooves 35a, 35b so as to be vertically movable. The resin vertical frames 34c and 34d are provided so as to cover the interior facing surface of the opening groove 35a on the exterior side. Therefore, the vertical frames 28c and 28d are further provided with resin-made vertical frame attachment members 36 which are made of PVC or the like and which cover the interior facing surfaces of the interior-side opening grooves 35b. As a result, the interior facing surfaces of the vertical frames 28 c and 28 d are substantially formed by the vertical frame attachment member 36 .

The outer shoji 29 and the inner shoji 30 are ventilation shoji. The outer shoji 29 has a panel 38 supported on all four sides by a ventilation frame 39 . The inner shoji 30 has a panel 40 supported on all four sides by ventilation frames 41 . The face materials 38 and 40 are, for example, multi-layered glass in which two sheets of plate glass are arranged with a spacer interposed therebetween. The ventilation frames 39 and 41 have a composite structure in which a metal frame made of an extruded shape such as an aluminum alloy and a resin frame made of an extruded shape such as PVC are combined.

The screen door device 31 is provided so as to cover the shojis 29 and 30 from the outdoor side. The screen door device 31 has a screen door frame 31a fixed to the outdoor side face of the ventilation opening frame 28, and a screen door 31b supported by the screen door frame 31a. The screen door 31b is, for example, a roll type that can be raised and lowered. The screen door device 31 may be omitted.

Next, the specific configuration of each part of the fittings 10 and the effects thereof will be described. First, the connection structure between the frame 22 and the ventilation opening frame 28 will be described.

In general, in fittings having a ventilation unit, the same member is used for both the frame of the door body and the ventilation opening frame of the ventilation unit. On the other hand, in the fitting 10 of the present embodiment, the frame 22 and the ventilation opening frame 28 are configured as separate members, and the ventilation opening frame 28 is connected to the frame 22 .

As shown in FIG. 4, the upper rail 22a has an upper connecting portion 44a on the frame inner projection surface 22a1 of the metal upper rail 23a. The upper connecting portion 44a is hidden on the indoor side of the outdoor-side viewing surface 22a2 of the upper frame 22a. The upper connecting portion 44a is composed of, for example, a pair of L-shaped plate pieces. In this embodiment, one of the plate pieces forming the upper connecting portion 44a is provided on the rear surface of the outdoor side viewing surface 22a2.

The upper frame 28a is connected to the upper frame 22a by engaging the upper connecting portion 44a with the engaging piece 44b on the room-side end of the metal upper frame 33a. The metal upper frame 33a has a draining surface 33a1 inclined downward toward the outside of the room, and a hollow portion 33a2 provided behind the draining surface 33a1. The engagement piece 44b is formed at a portion of the drain surface 33a1 bent upward at the indoor-side end. The metal upper frame 33a has a mounting portion 45a in a portion hidden inside the frame of the hollow portion 33a2. The resin upper frame 34a is connected to the metal upper frame 33a by engaging the engaging piece 45b at the outdoor end with the mounting portion 45a.

As shown in FIG. 4, the upper frame 28a is provided so as to protrude to the outdoor side from the outdoor side viewing surface 22a2 of the upper rail 22a. At this time, as for the boundary between the upper frame 22a and the upper frame 28a, since only the boundary line between the outdoor side viewing surface 22a2 and the draining surface 33a1 is exposed to the exterior of the fitting 10, the appearance quality is not impaired. Moreover, although both the upper frame 22a and the upper frame 28a are composite structures of metal and resin, the exterior surface thereof is composed of the continuous metal upper frame 23a and the metal upper frame 33a. Therefore, the connecting body of the upper frame 22a and the upper frame 28a has high rigidity and fireproof performance.

Further, in the fitting 10, the upper connecting portion 44a and the engaging piece 44b are hidden behind the exterior facing surface 22a2 of the metal upper frame 23a. Therefore, even when the upper frame 22a and the upper frame 28a receive the heat of a fire from the outside of the room, for example, it is possible to prevent the upper connecting portion 44a from being disengaged. Moreover, since the upper connecting portion 44a and the engaging piece 44b are located above the draining surface 33a1, the waterproof performance is also high. In addition, in the fitting 10, since the mounting portion 48a of the resin top frame 34a to the metal top frame 33a is located on the inner surface of the metal top frame 33a, it is possible to prevent the resin top frame 34a from falling off from the metal top frame 33a in the event of a fire. can. In particular, since the mounting portion 48a is hidden inside the frame of the hollow portion 33a2 provided in the metal upper frame 33a, the heat insulating action of the hollow portion 33a2 further improves the fire prevention performance.

Next, as shown in FIG. 6A, the total length (length in the X direction) of the upper frame 28a is configured to be shorter than the total length (length in the X direction) of the upper frame 22a. Therefore, a step L is formed between the fore end face 22a3 of the upper frame 22a and the fore end face 28a1 of the upper frame 28a due to the difference in overall length. That is, the fore end face 28a1 of the upper frame 28a is offset inward from the fore end face 22a3 of the upper frame 22a. Although FIGS. 6A and 6B only show one end of the upper frame 22a and upper frame 28a, the other end also has a substantially symmetrical structure.

That is, the fitting 10 includes the ventilation unit 21 . Therefore, as shown in FIGS. 3 and 6B, in the fitting 10, the ventilation opening frame 28 protrudes from the inside of the frame of the frame 22 to the outside of the room. Therefore, the above-described step L is required between the upper frame 22a and the fore end surfaces 22a3 and 28a1 of the upper frame 28a. Therefore, the door frame 22c and the meeting frame 22d, which are vertical frames, straddle the step L and cover the fore end surfaces 22a3 and 28a1, and are screwed to the fore end surfaces 22a3 and 8a1.

In this way, the upper frame 22a, which is a horizontal frame, and the upper frame 28a, which is a horizontal frame, are connected by separate members, forming a step L between the edge end faces 22a3 and 28a1. As a result, the fitting 10 does not need to be post-processed to form the step L on the fore edge surface 28a1. That is, in the general fittings described above, since the frame of the door and the ventilation opening frame of the ventilation unit are made of one member, additional processing for forming the step L is required. On the other hand, the fitting 10 of the present embodiment does not require additional processing for the step L, and has high manufacturing efficiency. Although the upper resin frame 34a is not shown in FIGS. 6A and 6B, the overall length of the upper resin frame 34a is the same as the overall length of the metal upper frame 33a, and the edge surface thereof is flush with the edge surface 28a1. .

Next, the connection structure between the lower frame 22b and the lower frame 28b and the waterproof structure by the lower frame 28b will be described.

As shown in FIG. 5, the lower stile 22b has a lower connecting portion 48a above the exterior facing surface 22b1 of the metal lower stile 23b. The lower connecting portion 48a is composed of, for example, an L-shaped plate piece and a concave portion facing each other. The lower frame 28b has an engaging piece 48b on an indoor side face 28b1 that overlaps the outdoor side face 22b1 of the lower frame 22b. The lower frame 28b is connected to the lower frame 22b by engaging the engaging piece 48b with the lower connecting portion 48a.

The metal lower frame 33b has a receiving surface 33b1, a gutter-shaped portion 33b2, and a draining surface 33b3 in order from the indoor side to the outdoor side. The receiving surface 33b1 is an inclined surface inclined downward toward the outdoor side. The gutter-shaped portion 33b2 protrudes downward on the outdoor side of the receiving surface 33b1 and has a groove shape. The draining surface 33b3 is an inclined surface that slopes downward toward the outdoor side on the outdoor side of the gutter-shaped portion 33b2. The engagement piece 48b is provided on the indoor side face 28b1 of the gutter-shaped portion 33b2 facing the outdoor side face 22b1 of the lower rail 22b.

The receiving surface 33b1 and the gutter-shaped portion 33b2 face the lower end portion 30a of the inner shoji 30, that is, the lower frame of the ventilation frame 41, and cover it in the prospective direction. Specifically, the indoor end of the receiving surface 33b1 is on the indoor side than the indoor surface of the inner shoji 30, and the outdoor end of the gutter-shaped portion 33b2 is on the outdoor side of the outdoor surface of the inner shoji 30. be. Of course, the receiving surface 33b1 and the gutter-shaped portion 33b2 also cover the lower end portion 30a of the inner shoji 30 in the longitudinal direction. At this time, the gutter-shaped portion 33ba1 is arranged on the outdoor side of the outdoor side viewing surface 22b1 of the lower rail 22b and overlaps the upper portion of the outdoor side viewing surface 22b1. At this time, the receiving surface 33b1 and the gutter-shaped portion 33b2 are formed of one shape member including the draining surface 33b3.

Accordingly, the lower frame 28b is also provided so as to protrude to the outdoor side from the outdoor side facing surface 22b1 of the lower frame 22b. At this time, the lower frame 28b has a receiving surface 33b1 and a gutter-shaped portion 33b2 on the metal lower frame 33b, and covers the lower end portion 30a of the inner shoji 30 with these. For this reason, in the fitting 10, rainwater, condensation water, etc. that has flowed down the indoor and outdoor surfaces of the inner shoji 30 are trapped by the metal receiving surface 33b1 and the gutter-shaped portion 33b2, and are appropriately discharged to the outdoor side as described later. be. As a result, the fitting 10 can obtain high waterproof performance. In addition, since the gutter-shaped portion 33b2 overlaps with the outdoor side facing surface 22b1 of the lower frame 22b and protrudes downward, the volume of the gutter-shaped portion 33b2 is increased, the water storage amount is improved, and the drainage performance is further improved. become good.

The fitting 10 of the present embodiment penetrates the interior facing surface 28b1 of the gutter-shaped portion 33b2 and the exterior facing surface 22b1 of the lower rail 22b, allowing water to flow from the gutter-shaped portion 33b2 into the lower rail 22b. A communication port 50 is provided. Therefore, water flowing from the receiving surface 33b1 to the gutter-shaped portion 33b2 passes through the communication port 50 while flowing through the gutter-shaped portion 33b2. The water that has passed through the communication port 50 flows down inside the metal lower frame 23b and is discharged to the outdoor side through a drainage component 51 provided on the outdoor side viewing surface 22b1, for example. At this time, the communication port 50 passes through the lower connecting portion 48a between the lower frame 22b and the lower frame 28b. For this reason, water stopping around the communication port 50 can be easily performed by, for example, providing a water stopping material at the connecting portion between the lower connecting portion 48a and the engaging piece 48b.

The drainage path from the gutter-shaped portion 33b2 is not limited to this. For example, like a drain component 51 indicated by a chain double-dashed line in FIG. 5, a drain port may be provided directly on the outdoor side face of the gutter-shaped portion 33b2. Further, for example, like a drain port 52 shown in FIG. 5, a path may be provided for draining water flowing down inside the metal lower frame 23b to the outside of the room through the lower end surface of the metal lower frame 23b.

In addition, as shown in FIG. 5, the resin lower frame 34b has a facing piece 34b1 and a projection piece 34b2, and is formed to have a substantially L-shaped cross section. The facing piece 34b1 covers the interior facing surface of the protruding piece 33b4 that protrudes upward from the interior-side end of the metal lower frame 33b. The projected piece 34b2 protrudes toward the outside of the vehicle so as to cover the frame-outside projected surface of the receiving surface 33b1. The lower resin frame 34b is attached to the lower metal frame 33b by engaging the upper end of the facing piece 34b1 and the tip of the connecting piece 34b2 with the lower metal frame 33b. As a result, the resin lower frame 34b can reliably cover the portion of the metal lower frame 33b exposed to the interior side, and the appearance quality and heat insulating performance are further improved.

Next, as shown in FIG. 7A, the total length (length in the X direction) of the lower frame 28b is also shorter than the total length (length in the X direction) of the lower rail 22b. As a result, a step L is also formed between the edge end face 22b2 of the lower frame 22b and the edge face 28b2 of the lower frame 28b due to the difference in overall length. 7A and 7B illustrate only one end of the lower frame 22b and the lower frame 28b, the other end also has a substantially bilaterally symmetrical structure.

In this manner, the lower frame 22b, which is a horizontal frame, and the lower frame 28b, which is a horizontal frame, are also connected by separate members, forming a step L between the edge end surfaces 22b2 and 28b2. Therefore, the fitting 10 does not require additional processing for forming the step L on the edge face 28a2 of the lower frame 28b (see FIG. 7B), further improving manufacturing efficiency. Further, since the lower frame 22b and the lower frame 28b are separate members, the metal lower frame 33b can be formed into a desired saucer shape regardless of the shape of the lower frame 22b, further improving the waterproof performance.

Next, the relationship between the door body 14 and the mullion 12d will be described.

As shown in FIG. 8A, the mullion 12d is in contact with the meeting frame 22d (metal meeting frame 23d) with the door body 14 in the fully closed position, and the smoke returners 54 and 55 are connected to each other. facing outward. At this time, the chamfered portion 20 of the mullion 12d forms a recessed portion 56 between it and the surface of the door body 14 on the interior side. The recessed portion 56 is a recessed space that opens toward the inside of the frame of the opening frame 12 .

The recess 56 is surrounded on three sides by a first inner surface 56a facing the outside of the room, a second inner surface 56b facing the inside of the frame, and a third inner surface 56c facing the inside of the room. The first inner surface 56 a is formed by a portion of the surface of the cubic attachment member 17 that covers the inner surface 20 a that is the exterior facing surface of the chamfered portion 20 . The second inner surface 56 b is formed by a portion of the surface of the mullion attachment member 17 that covers the inner surface 20 b that is the frame inner surface of the chamfered portion 20 . The third inner surface 56c is formed by the indoor-side facing surface of the vertical frame attachment member 36 attached to the vertical frame 28d of the ventilation unit 21. As shown in FIG.

Accordingly, in the fitting 10, when the concave portion 56 is viewed from the inside of the room as indicated by an arrow A in FIG. 8A, the metal joining frame 23d, which is a metal member, is not substantially exposed. In other words, substantially the entire inner surfaces 56a to 56c of the recess 56 are formed by the attachment members 17 and 36, which are resin members. Therefore, the fitting 10 can obtain high heat insulation performance and appearance quality.

By the way, the frame body 22 has a composite structure of a metal frame member 23 and a resin frame member 24, and the opening frame 12 including the mullion 12d has a similar structure. Here, the resin material can be easily colored and can be formed in a color according to the user's preference, but it is not easy to change the color of the metal material.

Therefore, in the fitting 10, for example, a laminate film 58 (indicated by a dashed line in FIG. 8A) having the same color as the surrounding resin material is attached to the surface exposed to the outside of the metal interlocking frame 23d to ensure the appearance quality. are doing. In the case of the metal stile 23d, the laminate film 58 covers, for example, the frame-outside projection surface 23d1 and the outdoor-side projection surface 23d2.

On the other hand, the metal stile 23d is hidden by the resin attachment members 17 and 36 and is not exposed to the outside. not That is, since the surfaces 23d3 and 23d4 of the metal fitting frame 23d are hidden by the resin attachment members 17 and 36, the laminate film 58 does not need to be provided. As a result, the joining area of the laminate film 58 can be minimized in the fitting 10, and the work cost and parts cost can be reduced.

By the way, in the fitting 10 of the present embodiment, the frame inner side portion 23d5 of the metal interlocking frame 23d is exposed to the concave portion 56 (see FIG. 8A). However, since the frame inner portion 23d5 is only slightly exposed from the gap between the inner surfaces 56b and 56c, even if the laminate film 58 is not provided, the appearance quality is hardly affected. Moreover, when the fitting 10 is in the fully closed position shown in FIG. 8A, the frame inner prospective surface 23d3 (and the frame inner portion 23d5) of the meeting frame 22d is aligned with the frame inner prospective surface 17a of the mullion attachment member 17 and the mullion 12d. It is arranged at a position offset to the outside of the frame with respect to the frame inner projection surface 12d1. That is, the meeting frame 22d has a smaller opening width than the mullion 12d. As a result, the fitting 10 can suppress the amount of protrusion of the metal interlocking frame 23 d into the recess 56 , and further suppress the exposure of the metal interlocking frame 23 d to the recess 56 .

Of course, the laminate film 58 may be provided on the frame inner portion 23d5. Alternatively, for example, the width of the metal stile 23d may be reduced to the outside of the frame to completely prevent the inside portion 23d5 of the frame from being exposed to the recess 56. FIG.

As shown in FIG. 8B, in the fitting 10 of the present embodiment, the concave portion 56 opens inside the frame.

A fitting according to an aspect of the present invention is a fitting comprising an opening frame, a door body that slides within the opening frame, and a ventilation unit attached to the door body, wherein the door body is made of metal. A meeting frame is provided, and the opening frame has a mullion that joins the meeting frame when the door body is in the fully closed position, and the mullion is on the outdoor side of the inner surface of the frame. It has a chamfered portion that is formed as if a corner is notched and forms a concave portion between itself and the door body, and a resin-made upright attachment member that is provided so as to cover the surface of the chamfered portion. The ventilation unit includes a vertical frame connected to the frame inner projection surface of the meeting stile, and is mounted on the vertical frame to form the interior facing surface of the vertical frame. a vertical frame attachment member forming an inner surface of the recess. According to such a configuration, by forming the inner surface of the recess with the resin mullion attachment member and the vertical frame attachment member, high heat insulation performance and appearance quality can be obtained while ensuring the amount of opening of the door by the recess. be done.

The width of the meeting stile is smaller than the width of the mullion, and when the door body is in the fully closed position, the inner side of the frame of the meeting stile faces the frame of the mullion attachment member. It may be configured to be arranged at a position offset to the outside of the frame from the inner projection surface. By doing so, it is possible to suppress the projecting length of the meeting stile into the recess, and to suppress the metal meeting stile from being exposed to the recess and degrading the appearance quality.

When the door body is in the fully closed position, the recess has a first inner surface facing the outside of the room, a second inner surface facing the inner side of the opening frame, and a third inner surface facing the inside of the room. , wherein the first inner surface and the second inner surface are formed by the mullion attachment member, and the third inner surface is formed by the vertical frame attachment member. By doing so, each inner surface of the recess can be made of a resin member, and heat insulation performance and appearance quality can be ensured.

The door body may have a door frame, and the recess may be configured to open to face the inner side of the opening frame. By doing so, the concave portion can smoothly pull in the door frame while ensuring heat insulating performance and appearance quality and avoiding interference.

The mullion attachment member may have a pocket portion for attaching a tight material that abuts on the indoor surface of the door body, and the pocket portion may be arranged at a position not forming the inner surface of the recess. good. By doing so, it is possible to prevent the tight material from interfering with the door frame and the pull part attached thereto, and also improve the appearance quality of the inner surface of the recess.

The meeting stile may be provided with a laminate film on the frame-outside projection surface and the outdoor-side facing surface, and may not be provided with the laminate film on the frame-inside projection surface and the indoor-side projection surface. That is, in the fitting, since the concave portion is formed of a resin member, the metal meeting frame is not largely exposed in the concave portion. As a result, the fitting can have a high appearance quality without providing a laminate film on this part, so the area where the laminate film is adhered can be minimized, and the work cost and parts cost can be reduced.

It goes without saying that the present invention is not limited to the above-described embodiments, and can be freely modified without departing from the gist of the present invention.

In the above description, the attachment members 16, 17, 36, the resin frame member 24, and the resin frame member 34 are exemplified as members to be attached to the interior side of the room or the inner side of the frame of the metal member. Other than that, for example, wood or the like may be used.
