Description

[Detailed description of the invention] This invention enables the door roller inserted between the rails to be easily rotated so that it runs on the rail when the hanger door roller of a folding door installed in a bathroom, etc. is installed across the rail. This relates to erection equipment.

Folding doors, which are generally installed in bathrooms, have a pair of door wheels mounted oppositely on both ends of a horizontal shaft at the top of a rotatable vertical door wheel mounting shaft that protrudes from the upper ends of the hanging side and the running side. A hanger door roller consisting of a metal roller is inserted between the rails from below and straddled on rails that are installed on the upper frame of the opening with a gap wider than the diameter of the door roller, so that the door roller can be opened and closed. However, in order to straddle the rails with a door roller inserted between the rails from below, the door roller must be rotated horizontally around the mounting axis above the rail. It is necessary to match the running direction with the longitudinal direction of the rail. For this reason, conventionally, as shown in Fig. 4, a horizontal through-hole is bored in the rotatable mounting shaft, and a rod-shaped body inserted through the through-hole is turned by hand to rotate the door wheel. However, in this case, the rod-shaped body A must be operated in the gap between the rail attached to the upper frame and the folding door body, and the gap between the upper frame and the folding door body cannot be made large, so the above gap is Because of this, it is not easy to insert the rod-shaped body into the small through hole.
It is extremely difficult to rotate the inserted rod-shaped body. Moreover, since the rod-shaped body is operated while lifting the folding door body, it is not possible to hang the hanger door wheels on the hanging base side and the running side at the same time, and because they are hung on one side at a time, unreasonable force is applied to the folding door body. In addition, there was the inconvenience of inadvertently damaging the folding door itself.

The present invention was devised in order to eliminate these inconveniences in view of the above-mentioned actual situation.The present invention was created in order to eliminate these inconveniences. The folding door body is constructed in a folded state with the hanger door roller inserted between the rails, although it is constructed using the same construction method as the conventional method, in which the rails are inserted between the rails from below and straddled over the opposing rails. A hanger for a folding door that allows the door roller to be rotated so that its running direction matches the longitudinal direction of the rail simply by opening the door, allowing the hanger door roller to be easily hung without any particularly troublesome operations. For the purpose of providing a door roller erection device, in particular, through-holes are drilled in the vertical door roller mounting shafts on both the hanging side and the running side in a direction perpendicular to the upper horizontal axis, and both through-holes are Insert and latch both ends of a string-like body that is shorter than the distance between the door rollers on the hanging side and the traveling side when the folding door is opened, and the door roller mounting shaft is tightened by the string-like body that is tensed in conjunction with the opening operation of the folding door. The door roller is characterized by being configured so that it rotates and the door roller runs on the rail.

The structure of the present invention will be explained based on an embodiment shown in the drawings. 1 is a folding door body formed by foldably connecting door bodies 3, 3 via a center stile 2; At the upper part of the hanging side and the running side of the folding door body 1, there is a hanger formed by a pair of door wheels 5, 5 being pivoted via a horizontal shaft 6 to the upper part of a vertical door wheel mounting shaft 4 which is rotatably protruded. Door roller 7 is attached. 8 is a door frame, and the door frame 8 is composed of an upper frame 9, a lower frame 10, and vertical frames 11 and 12, and a concave guide groove 13 is formed on the lower surface of the upper frame 9. The rails 14, 14 are placed opposite each other with an interval wider than the diameter of the door roller 5. And hanger door car 7
is inserted between the opposing rails 14, 14 from below,
By rotating the door roller 5 until its running direction matches the longitudinal direction of the rail 14 and placing it astride the rail 14, the folding door body 1 can be opened and closed within the door frame 8. Reference numeral 15 denotes a through hole drilled in the door roller mounting shaft 4 in the running direction of the door roller 5, and when the folding door body 1 is hung on the rails 14, 14 so as to be openable and closable, it is connected to the hanging base side. The through holes 15, 15 bored in the side door roller mounting shafts 4, 4 are arranged to face each other on the same axis parallel to the rail 14. 16 is the through hole 15,1
5 is a string-like body that is inserted and hooked at both ends to connect the door roller mounting shaft 4 on the hanging side and the door roller mounting shaft 4 on the traveling side, and the string-like body 16 The folding door body 1 is opened in a folded state with the hanger door roller 7 inserted between the opposing rails 14, 14. In conjunction with the movement in the direction, tension is created between the door roller mounting shafts 4, 4 on the hanging side and the running side, and the door roller mounting shafts 4, 4 are rotated by the tension of the tensioned string-like body 16. The door rollers 5, 5 are configured to run on the rails.

In the above configuration, when hanging the folding door body 1 on the rails 14, 14, first assemble the door frame 8, and then attach it to the folding door body 1 in a folded state. Hanger door roller 7,7
If the horizontal shaft 6 is inserted from below between the opposing rails 14, 14 so that it is parallel to the longitudinal direction of the rail 14, the rails 14, 14 will have a gap wider than the diameter of the door roller 5. Since the folding door body 1 is folded, it can be easily inserted, and if the folded door body 1 is then moved in the direction of opening, the hanger door roller 7 on the hanging side and running side attached to the folding door body 1 can be inserted. , 7 are gradually separated, and as a result, the string-like body 16 connecting the door roller mounting shafts 4, 4 becomes tense. Then, the door roller mounting shafts 4, 4 are rotated by the tension of the string-like body 16, and when the above-mentioned string-like body 16 is further tightened and becomes straight, the through-hole 1 through which the string-like body 16 penetrates
5 and 15 are located on the same axis parallel to the rail 14, and the through holes 15 and 15
are bored in the direction of travel of the door wheels 5, 5, so simply operating the folding door main body 1 in the folded state in the direction of opening will ensure that the door roller 5 is opened without any troublesome operation. , 5 are now running on the rails 14, 14, and the hanger door roller 7 can be easily hung on the rails 14, 14. Then, by further operating the folding door main body 1 in the direction of opening, the string-like body 16 can be easily cut and removed.

In short, in the present invention, a pair of door rollers are pivotally supported at both ends of a horizontal shaft with an interval wider than the diameter of the door rollers.
Both hanger door rollers, which rotatably support the upper parts of the hanging side and running side of the folding door, respectively, are mounted on a vertical door roller mounting shaft hanging from the center of the horizontal axis, with an interval wider than the diameter of the door roller. Insert the two hanger door rollers between the two rails from below, with the horizontal axes of the two rails facing each other in the same direction as the longitudinal direction of the rails;
Next, in a folding door that is built by rotating the same horizontal shaft in the width direction of the rail, a through hole is drilled in the vertical double door car mounting shaft in a direction perpendicular to the horizontal axis, and the folding door is installed in both through holes. Insert and hook both ends of a string-like body that is shorter than the mounting interval of the door roller on the travel side on the hanging side when opened, and tension the string-like body by the opening operation of the folding door, and then connect both horizontal shafts to the rails. It is structured so that both hanger door rollers are built on the rails by rotating in the width direction of the rails, and the structure is the same as the conventional one, in which the two hanger door rollers are inserted from below the opposing rails and straddled between the rails. However, by simply opening the folding door in a folded state, the string-like body that connects the door roller mounting shaft on the hanging side and the running side rotates the door roller mounting shaft, ensuring that the door roller runs. The present invention has extremely useful practical effects in that the hanger door roller can be easily hung without any particularly troublesome operations, and the efficiency of the hanger door roller erecting work can be improved.
