Since the guide rail outset on the wall surface protrudes from the wall surface, a load due to the load of the door body may be applied to the mounting portion, which may cause deformation of the mounting portion, reduction of the fixing force, and the like. Therefore, for example, it is desired to firmly fix the mounting portion to the wall surface by extending the mounting portion of the guide rail in the vertical direction and striking screws from the directions perpendicular to the extension portions of the upper part and the lower part thereof. ..

However, when the mounting portion of the guide rail is extended downward, there is a problem that the mounting portion at the lower part of the guide rail interferes with the rotating track of the folding door when the door body is a folding door that draws a rotating track when opening and closing. However, if the distance between the guide rail and the folding door is increased in order to avoid interference between the guide rail and the folding door, the gap between the guide rail and the folding door becomes large, and the lower mounting part can be visually recognized from the gap. There is a problem that is reduced.

According to the present disclosure, a guide rail mounting structure and a guide thereof, which can firmly fix the guide rail to the wall surface, do not interfere with the case where the door body that draws a rotating track is suspended, and have excellent design. It is an object of the present invention to provide fittings using rails.

It extends in a substantially horizontal direction toward a certain chamber R2 side. The second fixing piece 313 is arranged orthogonal to the first fixing piece 312 and parallel to the lower surface 4c of the base material 4. The width of the second fixed piece 313 along the prospective direction is substantially the same as the width of the lower surface 4c of the base material 4 along the prospective direction. The prospective direction is a direction extending over the chamber R1 and the chamber R2 with the opening 104 in between, and is a left-right direction in FIG. Since the second fixing piece 313 covers and blindfolds the entire lower surface 4c of the base material 4, the design of the guide rail 3 as seen from the lower surface side is also improved.

In the guide rail main body 31, the first fixing piece 312 is brought into contact with the side surface 4a of the base material 4, and the base material 4 is moved from above and below by the first piece 318a and the second fixing piece 313 of the upper end piece 318. It is attached to the base material 4 so as to sandwich it. A gap 108 corresponding to the thickness of the second fixing piece 313 is formed between the portion of the upper surface 101a of the upper frame member 101 protruding toward the chamber R1 and the lower surface 4c of the base material 4. The second fixing piece 313 is inserted into the gap 108.

After the guide rail main body 31 is attached to the base material 4, the first fixing piece 312 and the second fixing piece 313 are fixed by screws SC2 and SC3, which are fixing members, respectively. The screw SC2 is driven into the upper portion 312a of the fixing piece arranged above the connecting portion with the upper connecting plate 316 in the first fixing piece 312 from a direction perpendicular to the wall surface 100a.

The rising portion 315a of the lower protruding piece 315 of the guide rail main body 31 comes into contact with the inner surface 321a of the front cover portion 321 and stably supports the front cover portion 321. Further, the sandwiching piece 323 of the upper surface cover portion 322 sandwiches the second piece portion 318b of the upper end piece 318 of the guide rail main body 31.

The resin caps 33, 33 are formed in a rectangular shape corresponding to the shapes of both end faces of the guide rail main body 31 and the resin cover 32. As shown in FIGS. 1, 2 and 3, the resin caps 33 and 33 are detachably attached so as to cover both end faces of the guide rail main body 31 including the base material 4 and the resin cover 32.

When the door body 2 is attached to the guide rail 3 outset on the wall surface 100a in this way, the door body 2 is attached to the traveling portion 311 of the guide rail main body 31 before attaching at least one of the resin caps 33. The suspension wheels 25 and 27 of the above are inserted while sliding, and the guide roller 26 is fitted into the groove portion 311d between the rail portions 311c and 311c of the traveling portion 311. Since the door body 2 is suspended by the two suspension wheels 25 and 27, the door body 2 can be moved along the length direction of the traveling portion 311, and the position of the door body 2 can be easily adjusted. be able to. After the position adjustment of the door body 2 is completed, the suspension wheel 27 on the door tail side is fixed by using a fixing bracket (not shown) so as to be immovable in the traveling portion 311 and at the lower end portion on the door tail side. The shaft portion 28 is engaged with the bearing 281 on the floor surface FL.

As shown in FIG. 3, the door body 2 attached to the guide rail 3 has an opening by deploying the door end door body 21, the intermediate door body 23, and the door tail door body 22 of the door body 2 in series. Close 104. The door end door body 21 is arranged so as to face the prospective surface of the new vertical frame member 105, and the door tail door body 22 is arranged so as to cover the existing vertical frame member 103 from the room R1 side. Since the guide rail 3 projects from the wall surface 100a toward the chamber R1 via the base material 4, the door body 2 with the opening 104 closed is arranged apart from the wall surface 100a. Therefore, interference between the vertical frame members 102 and 103 provided so as to project toward the chamber R1 and the door body 2 can be easily avoided. By attaching the guide rail 3 using the base material 4, the degree of separation of the door body 2 from the wall surface 100a, that is, the degree of avoiding interference with the vertical frame members 102 and 103 can be easily adjusted. .. The gap between the door end side of the door body 2 and the vertical frame member 102 caused by separating the guide rail 3 from the wall surface 100a is closed by the new vertical frame member 105. The gap between the door tail side of the door body 2 and the wall surface 100a is closed by the spacer material 107.

The opening operation of the door body 2 is performed as follows. When the handle 211 of the door body 2 is operated toward the chamber R1 side, as shown in FIG. 6A, the door end door body 21 is on the chamber R1 side centering on the rotation shaft 253 of the suspension wheel 25 constituting the movable rotation shaft. Rotates to. The rotation operation of the door end door body 21 is transmitted to the intermediate door body 23 via the hinge portion 24a, and the intermediate door body 23 also rotates toward the chamber R1 around the shaft portion 261 constituting the movable rotation shaft. To do. As a result, the door end door body 21 and the intermediate door body 23 begin to be folded so as to project toward the chamber R1 side. Further, the rotation operation of the intermediate door body 23 is transmitted to the door tail door body 22 via the hinge portion 24b, and the door tail door body 22 also rotates around the rotation shaft 273 and the shaft portion 28 toward the chamber R1 side. Move. As a result, the intermediate door body 23 and the door tail door body 22 begin to be folded so as to project toward the chamber R1.

Since the rotation shaft 273 and the shaft portion 28 of the door tail door body 22 form a fixed rotation shaft, the position of the rotation shaft of the door tail door body 22 with respect to the guide rail 3 is immovable. Therefore, the door end door body 21 moves toward the door end door body 22 while rotating as the suspension vehicle 25 travels in the traveling portion 311 toward the door end side. Along with this, the intermediate door body 23 moves toward the door tail door body 22 while rotating as the guide roller 26 slides the groove portion 311d toward the door tail side. As a result, as shown in FIG. 6B, the door end door body 21, the door tail door body 22, and the intermediate door body 23 are folded so as to overlap each other in parallel, and the opening 104 is opened. At this time, the rotation shaft 253 and the shaft portion 261 which are the movable rotation shafts of the door end door body 21 and the intermediate door body 23 are arranged at the end portions on the side close to each other, and thus are as shown in FIG. 6B. In addition, the door body 2 with the opening 104 opened is folded so as to project from the guide rail 3 toward the chamber R1 side, and does not project significantly toward the chamber R2 side.

Since the door body 2 with the opening 104 opened does not protrude significantly toward the chamber R2, the length of the guide rail 3 with respect to the opening 104, the size of each door body of the door body 2, the position of the stopper, etc. By making appropriate adjustments, as shown in FIG. 6C, it is possible to prevent the folded door body 2 from overlapping within the opening width of the opening 104 when the door body 2 is fully opened. According to this, since the opening 104 can be used as effectively as possible when the door body 2 is fully opened, for example, a wheelchair, a nursing bed, or the like can be easily moved.

The end side of the door body 2 made of a middle folding door, which is closer to the rotation axis than each rotation axis of the door end door body 21, the door tail door body 22, and the intermediate door body 23, slightly protrudes toward the chamber R2 side. Draw a rotating track. If the constituent portion of the guide rail 3 is present on the rotating track, it may interfere with the door body 2. However, as shown in FIG. 4, since the guide rail 3 has a substantially horizontal flat surface extending from the lower surface 311e of the traveling portion 311 to the side surface 101b facing the chamber R1 side of the upper frame member 101, the guide rail 3 and the door body 2 In the space extending the width W between the upper frame member 101 and the side surface 101b, there is nothing protruding downward from the guide rail 3. Therefore, the rotating trajectories of the door end door body 21, the door tail door body 22, and the intermediate door body 23 do not interfere with the guide rail 3. As a result, it is possible to reduce the gap between the door body 2 and the guide rail 3 as much as possible, and it becomes difficult to see the fixed portion of the guide rail 3 from the gap, and the fitting 1 The design of the rail is also improved.

As shown in FIG. 7, when the wall surface 100a and the side surface 101b of the upper frame member 101 are arranged flush with each other, the base material 4 may be attached from the wall surface 100a to the side surface 101b of the upper frame member 101. As a result, the guide rail 3 can be outset so that the lower surface of the guide rail 3 is flush with the lower surface 101c of the upper frame member 101.

The guide rail 3 may be directly fixed to the wall surface 100a without the base material 4 if there is no risk of interference between the door body 2 and the wall surface 100a, the frame material, or the like. In this case, as shown in FIG. 8, the first fixed piece 312 of the guide rail main body 31 is not provided with the first piece portion 318a of the upper end piece 318 protruding toward the wall surface 100a, and the resin cover 32 is correspondingly provided. The upper surface cover portion 322 of the above is also formed to be narrow. The first fixing piece 312 is in direct contact with the wall surface 100a and is fixed by the screw SC2 from a direction perpendicular to the wall surface 100a. The second fixing piece 313 directly abuts on the lower surface 100b of the wall portion 100 facing the opening 104, and is fixed from below by the screw SC3. In this case, the guide rail 3 can be outset so that the lower surface of the guide rail 3 is flush with the lower surface 100b of the wall portion 100.

In the above embodiment, the fitting 1 configured to outset the door body 2 to the opening 104 without removing the existing frame forming the opening 104 has been illustrated. However, the fitting 1 may be outset by removing a part or all of the existing frame forming the opening 104 at the time of remodeling, or can be attached to the opening of a new building. ..

The door body 2 as the middle folding door used for the fitting 1 may have at least the door front door body 21 and the door tail door body 22, and is not limited to the one composed of three door bodies. Further, the door body may be any one suspended above the guide rail 3, and may be a door body other than a middle folding door such as a sliding door or an accordion door.
