スペーサを挿入する必要があつた。 Conventionally, a guide spacer was inserted between the connecting tube and the hinge piece to prevent the hinge piece from wobbling, but since it is inserted separately, a means for holding the guide spacer is required. In order to reduce the number of holding means, it was necessary to insert a long guide spacer along the entire length of the connecting tube.

構造を提供するにある。 The present invention was made in view of the drawbacks of the conventional examples mentioned above, and its purpose is to hold the guide spacer by integrally protruding the guide spacer from the latch, handle, and drop built into the connecting tube. To provide a structure of a hinge part of a folding door, which can shorten a guide spacer without requiring a separate means.

み扉Ａが滑かに折畳まれるようになつている。 The present invention will be explained in detail below with reference to the accompanying drawings. As shown in FIGS. 2 and 4, a connecting cylinder 1 having a substantially C-shaped cross section
A rounded shaft-shaped portion 2 is formed at both ends of the door panel 3, and a hinge piece 4 bent in an arc is protruded outward from the side edge of the door panel 3, so that each hinge piece 4 of the two door panels 3 The hinge pieces 4 of both door panels 3 are inserted into the connecting cylinder 1 and slidably engaged with the outer periphery of the shaft-shaped portion 2, thereby connecting the two door panels 3 to each other in a manner that allows the folding door A to be folded. It is configured so that Furthermore, as shown in FIG. 5, the connecting tube 1 is provided with notches 10 at three locations at the top, middle, and bottom.
Inside this notch 10 is a latch 6 that locks onto the upper rail 5 to hold the folding door A in a closed state.
, a foldable handle 7 for opening and closing, and a droplet 8 for locking.
and are attached to each other and fixed by means such as screws. Round rod-shaped guide spacers 9 are integrally projected from the latch 6, handle 7, and drop 8 installed in the connecting tube 1, and the guide spacers 9 of the latch 6 are inserted into the connecting tube 1 as shown in FIG. The upper and lower guide spacers 9 of the handle 7 are fitted between the inner surface of the connecting cylinder 1 and the hinge piece 4 as shown in FIG. is fitted between the inner surface of the connecting cylinder 1 and the hinge piece 4 as shown in Fig. 2 to prevent the hinge piece from rattling, so that the folding door A can be folded smoothly.

るものである。 Since the present invention is constructed as described above, the folding door can be opened and closed smoothly by preventing rattling due to the function of the guide spacer, and the guide spacer is integrally formed with the latch, handle, and drop. There is no need for a separate holding means to hold the guide spacer, the structure is simple, and there is an advantage that the guide spacer can be divided into pieces instead of a single piece, making it possible to shorten the guide spacer. Although the guide spacers do not extend over the entire length of the guide spacer, the guide spacers are arranged at the upper end, the center, and the lower end, so the same effect can be achieved as if the guide spacers did not extend over the entire length.
