Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a folding door that can be folded into a small zigzag shape when not in use.

[Background technology]

In the past, runners, slide pins, etc. were attached to the upper or lower end of the hinge frame, so the upper or lower ends of the hinge arm of the door panel body had to be cut out, which caused manufacturing delays. The number of processes increased, resulting in poor efficiency.

[Purpose of the invention] The present invention was made in view of the drawbacks of the conventional example described above, and its purpose is to simplify the mounting structure of parts such as runners and slide pins, and to improve the hinge arm of the door panel body. The purpose is to allow runners, slide pins, etc. to be attached without cutting out the.

[Disclosure of invention]

The present invention has openings 1 on both side edges of a hinge frame 2 having a substantially C-shaped cross section and having an opening 1 along its entire length.
A shaft portion 3 is provided on either side of the door panel body 4, and a hinge arm 5 having a substantially C-shaped cross section is provided protruding from the side edge of the door panel body 4.
Each hinge arm 5 of the adjacent door panel body 4
is inserted into the hinge frame 2 through the opening 1 and rotatably locked on the outer periphery of the shaft portion 3, and a spacer 6 formed in a hollow cylindrical shape is inserted into the hinge frame 2 over substantially the entire length. The outer peripheral surface of the spacer 6 is brought into contact with the hinge arm 5, parts such as the runner 7, slide pin 8, ratchet roller 9, etc. are inserted into the upper or lower end of the spacer 6, and locking grooves are formed on both sides of the spacer 6. 11, a stopper 12 for preventing rotation of the spacer 6 is fitted into the locking groove 11, and the stopper 12 is fixed to the hinge frame 2 with screws 13, thereby achieving the above object. It could have been done.

The present invention will be explained in detail below with reference to the accompanying drawings. Reference numeral 2 denotes a hollow hinge arm made of aluminum or the like, which is formed into a substantially C-shaped cross section, and has an opening 1 extending over the entire length of one side, and both sides of the hinge frame 2 with the opening 1 in between. A substantially cylindrical shaft portion 3 is provided on the edge over the entire length of the upper and lower sides. Shaft part 3
The inner diameter of the hole is a tapping hole. Reference numeral 4 denotes a plurality of door panel bodies for configuring the folding door A, and from the end cover 10 attached to the side end surface of the door panel body 4, a hinge arm having a substantially C-shaped cross section extends over the entire vertical length. 5 is made to stand out. Then, each hinge arm 5 of the adjacent door panel element body 4 is inserted into the hinge frame 2 through the opening 1, and the hinge arm 5 is rotatably locked to the outer periphery of the shaft portion 3, and the adjacent door panel element body 4 is inserted into the hinge frame 2 through the opening 1. The four members are rotatably hinged together, and the door panel elements 4 are folded in a zigzag manner via the hinge frame 2, as shown in FIG.
In addition, in order to insert the hinge arm 5 into the hinge frame 2, it may be inserted from the opening 1 due to the size, or the hinge arm 5 may be slid from the upper end of the hinge frame 2. Reference numeral 6 denotes a hollow spacer, which is inserted over the entire vertical length of the hinge frame 2 and brought into contact with the inner surface of the hinge frame 2 and the hinge arm 5, thereby preventing the hinge arm 5 from coming off. It is prevented from sticking. Further, a pair of locking grooves 11 are formed on the inner surface of the spacer 6 over the entire length.
As shown in the figure, a stopper 12 fitted into this locking groove 11 is fixed from the outside of the hinge frame 2 with a screw 13 to prevent the spacer 6 from rotating. As shown in FIG. 5, a runner 7 is inserted into the upper part of the spacer 6 and fixed with a cap 14, etc., and a slide pin 8 is inserted into the lower part to project downward. Further, a ratchet roller 9 is inserted into the upper part of the other spacer 6 so as to be able to slide up and down as shown in FIG. 6, and a compression spring 16 is delivered between it and the spring receiving plate 15 to urge the ratchet roller 9 upward. It has been done. Note that 17 is a handle formed integrally with the spacer 6.

As shown in Fig. 1, the folding door A constructed in this way is suspended between the upper and lower rails 18 and 19 by runners 7 and slide pins 8 provided on every other hinge frame 2. It's lowered. Further, the elastic material 20 at the end of the folding door A is fitted into a groove 21 in the door stop, so that the folding door A can be closed without any gaps.

[Effect of idea]

Since the present invention is constructed as described above, it is only necessary to insert parts such as runners and slide pins into the spacer, simplifying the mounting structure of the parts, and since the parts are housed inside the spacer, the hinge arm This has the advantage that parts can be attached without cutting out the hinge arm as in the conventional case. In addition, since the spacer is formed into a hollow cylindrical shape and the outer circumferential surface of the spacer is brought into contact with the hinge arm, the hinge arm is rotated by sliding on the outer circumferential surface which is now the circumferential surface of the spacer. Therefore, the hinge arm can be rotated smoothly, and the folding door can be folded smoothly.Furthermore, locking grooves are provided on both sides of the spacer, and locking grooves are also provided on both sides of the spacer. Since the fitted stopper is fixed to the hinge frame with screws, the spacer can be fixed to the hinge frame via the stopper, and the spacer is formed into a cylindrical shape for smooth rotation of the hinge arm. However, the spacer can be installed within the hinge frame without idling, so that there will be no hindrance to the installation of parts such as runners, slide pins, and ratchet rollers to the spacer. It is.
