Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the structure of a runner used to cover and assemble a folding door to a main body.

[Prior art] As shown in Japanese Utility Model Publication No. 51-48362, this type of folding door has conventionally been provided with rails on the upper and lower surfaces of the entrance and exit of the main body. A folding door runner is installed that protrudes from the side.

[Problem that the invention aims to solve] In the case of Jitsugoku No. 1983-48362, since the hanging rod protrudes in a straight line, the rotation locus becomes small, so the hanging rod is lengthened and has a large stroke. Therefore, the gap with the folding door when closed was too large. Since this gap is formed, when assembling it over the front surrounding the entrance/exit, work such as attaching a curtain plate separately is required, which has the fatal drawback that it cannot be commercialized as a cover assembly. It was inevitable.

By the way, when assembling a folding door cover, a certain distance is required between the back surface of the folding door and the front surface of the main body in order to prevent scratches caused by opening and closing of the folding door. Therefore, it was necessary to resolve the paradox of being able to run without rubbing in situations where the gap cannot be increased.

The purpose of the present invention is to provide a runner for assembling a folding door cover, which has been put into practical use in view of the above-mentioned circumstances, and which allows opening and closing of a folding door cover without causing friction even if the distance between the cover parts is brought closer together when closing. It's about doing.

[Means for Solving the Problems] The feature of the cover assembly runner according to the present invention for achieving the above object is that it has a substantially rectangular plate shape and is fixed in half to at least one of the upper and lower sides of the back surface of the folding door. a mounting member in which a U-shaped notch is formed from an end in one half; a tip of one piece is pivotally attached to the end of the mounting member; this one piece is accommodated in the notch of the mounting member; is integrally projected in a substantially L-shaped angle shape and is rotatable in the horizontal direction with respect to the mounting member, and the hanger is fixed to the protruding end of the other piece of the hanger and is provided in a vertically biased state. It is configured with a guide.

[Function] A substantially rectangular plate-shaped mounting member is fixed to the back surface of the folding door, and a guide can run inside the main body via an L-shaped hanger. In the closed position of the folding door,
One L-shaped piece of the hanger is accommodated and supported in the notch, and the space is closely spaced by the length of the accommodation.

In the open position, it is separated from the mounting member by the length of one L-shaped piece of the hanger, which is lengthened by the length of the notch, and the thickness of the L-shaped piece stored in the notch, so that the other L-shaped piece Combined with this, a large rotational trajectory is obtained, and the opening can be achieved without rubbing.

In the embodiment configured as described above, the guide 50 located at the upper part of the folding doors 1A, 1B
is attached to the upper guide groove 6A, and the lower guide 50 is attached to the lower guide groove 6B.

When the folding doors 1A, 1B are in the closed state, one angle piece 31 is positioned within the notch 12 as shown in FIG. 4b, and the outer surface of the other angle piece 33 is
3a comes into contact with the end surface 12a of the notch 12, the relative rotational movement between the mounting member 10 and the hanger 30 is stopped, and the other angle piece 33 is brought into a state of protruding rearward from the mounting member 10. This results in
A separation distance d is ensured as shown in FIGS. 3 and 4 a.

In addition, when opening the folding doors 1A and 1B, by operating the outsides of the folding doors 1A and 1B in a direction toward each other, the guides 50 of the runners 8 are guided inward from both ends of the upper and lower guide grooves 6A and 6B, and the folding doors are opened. 1A and 1B are folded and opened via the flag hinge 2 as shown by the phantom line in FIG. 4a. At this time, since the hanger 30 is prevented from rotating within the horizontal plane with respect to the guide 50, it moves laterally from the solid line shown in FIG. 4b to the virtual line shown while maintaining the distance d. Moreover, the shaft portions 20A and 20B are attached to the mounting member 10.
Since the mounting member 10 is provided at the end of the side plate B, the mounting member 10 does not come into contact with the front surface of the side plate B during opening and closing.

According to the embodiment, since the mounting hole 11 is provided in the unlocated portion of the angle piece 31, the mounting member 10 can be attached to the mounting screw without depending on the rotational position of the hanger 30 with respect to the mounting member 10. 9, it can be fixed to the folding doors 1A, 1B, and the runner 8 can be easily attached.

Furthermore, by installing the guide 50 of the upper runner 8 in the upper guide groove 6A, the square piece 42

In the above embodiment, the corner 33a of the other angle piece 33 is brought into contact with the end surface 12a of the notch 12, but the back surface 31a of the angle piece 31 is
It is also possible to implement a structure in which the above-mentioned rotation is stopped by bringing the folding door surface into contact with the folding door surface exposed in the notch 12.

In addition, in the embodiment, the angle piece 31
Although the angle piece 31 is positioned on the other half of the mounting member 10 in the above example, it is also possible to form the angle piece 31 on the shaft extending from the other half of the mounting member 10 to the other half. According to this modification, the other pieces of the angle are positioned closer to the inside of the folding door, so the left and right covering margins can be made wider.

Further, the shape of the guide 50 is not limited to a substantially rectangular parallelepiped in plan view, but may be formed in an elliptical, oval, or other shape in plan view. In each of the above embodiments, a pair of left and right folding doors 1A, 1B is illustrated, but a folding door structure in which a large number of folding doors are connected in a zigzag manner may also be used.

[Effects of the invention] As explained above, the invention has the following effects.

(b) When closing the folding door, by storing one L-shaped piece of the hanger in the notch of the mounting member, the other piece of the hanger protruding from the attachment member is shortened by the amount of storage, and the gap is created by the length of that part. In addition to being able to be kept small, during the folding process, the end of the other half located on the back side of the door serves as the pivot joint, and the L-shape extends from the end of the other half to the notch length toward the first half. By using one piece and the other L-shaped piece having the depth of the above-mentioned notch, a large rotation locus without rubbing was obtained, and the runner could be put to practical use as a cover assembly runner.

(b) Since the L-shaped piece of the hanger is stored in the notch of the mounting member, the back side of the door can be brought closer to the main body side by the amount of storage, and even if it is close, it can be opened and closed without rubbing. This makes it possible to reduce the distance between the back surface and the main body and perform close fitting assembly.

(c) Since the L-shaped piece of the hanger is stored in the notch extending from the end of the other half of the mounting member to the first half,
The cantilever load of the door acting on the pivoting part of the hanger can be supported by the notch of the mounting member along its length, and the load can be distributed during overlay assembly, resulting in a long service life. .

(d) Since a guide is fixed to the other protruding end of the hanger and biased in the vertical direction, when this guide is used on the top and bottom of the back of the door, for example, the guide can be moved downwards from the top as a reference. By allocating them, you can not only make the installation work easier, but also achieve smooth running with the vertical movement of the lower runners. Furthermore, it is possible to absorb errors occurring between the upper and lower sides.

(E) Since the guide and hanger are integrated,
It is sufficient to fix the mounting member to the back of the folding door and insert the guide into the main body, making the mounting work easy.
