Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hanging device for a folding door of furniture.

[Conventional technology]

Folding doors are sometimes used for furniture with larger openings than before. A folding door is made by connecting two doors with a hinge, and one of the doors is attached to the side panel of the furniture with a hinge, but if you just attach the two doors with a hinge like this, it will take a long time to make the door. Not only will the door sag under the weight, making it impossible to close completely when you close it, but the two doors may become as big as one door, making it unstable when opening and closing. Therefore, with folding doors, to prevent the door from falling down and to ensure that the two doors are always folded into a fixed shape, the door located far from the side panel of the furniture is suspended from a rail installed on the ceiling of the furniture. things are being done.

However, conventional hanging devices for hanging folding doors have the disadvantage that they do not run smoothly on the rails, and moreover, they tend to come off the rails.

[Purpose of invention]

The present invention was devised in view of the shortcomings of conventional hanging devices, and an object of the present invention is to provide a folding door hanging device that can smoothly open and close the door and run stably for a long period of time.

[Structure of the idea]

The inventor investigated the drawbacks of conventional hanging devices and found that when opening a folding door, the hanging device moves laterally along the rail while being subjected to an outward force that pulls the handle. It was found that the force in this direction hinders smooth running and makes it easier for the suspension device to come off the rail.

In the present invention, a groove is formed into which the lower surface of the rail can be easily inserted from the side surface of the main body of the suspension device, and the groove is used as a guide for the rail to facilitate smooth running of the suspension device.

〔Example〕

The present invention will be explained below based on the drawings.

The main body 1 of the suspension device has a groove 2 extending laterally therethrough. The groove communicates with a notch 3 that opens upward from the side of the main body, and the shape of the groove is such that the lower surface of the C-shaped rail R on which the suspension device is suspended can be easily inserted, as shown in Figures 1 and 4. It has become a thing. A door wheel 4 that protrudes into the groove is installed at the upper part of the groove 2. Leg-shaped hinge mounting portions 5, 5 are formed at the bottom of the main body. The arm of the angle hinge H installed on one folding door D is attached to the hinge attachment part, and the arm of the hinge is fixed by inserting a screw into the hole 6 drilled in the hinge attachment part. ing.

Next, the installation and operating conditions of the suspension device of the present invention having the above structure will be explained.

First, as shown in FIG. 1, attach the C-shaped rail R to the ceiling board T of the furniture using wood screws. At this time, the suspension device is placed in a state in which the rail is passed through the groove and suspended from the rail. Then, fix the arm of the angle hinge H installed at a predetermined position of the folding door D that is not attached to the side panel, that is, at a position that matches the hanging device suspended from the rail, to the mounting part 5 of the hanging device with screws. .

What is shown at the bottom of FIG. 1 is a guide device. The main body 10 of the guide device has a groove 11 with an opening at the top, and the lower part has a hinge attachment part similar to the hanging device of the present invention, although it is not shown in the drawing, and is an angle installed at the bottom of the folding door D. The arm of hinge H is fixed. The guide device prevents the lower part of the folding door from becoming unstable by holding the plate-shaped rail B installed on the lower surface of the floorboard F of the furniture between the grooves 11 of the main body.

In the hanging device of the present invention, the door roller slides on the lower surface of the rail inserted into the groove, and when the handle K of one folding door D is pulled outward, the side surface of the notch 3 in the groove moves to the side surface of the rail R. to prevent the door roller from coming off the underside of the rail. and folding door D
If you push the door to the right in Figure 2, the door roller will slide on the rail and the door will fold over and open completely as shown by the dashed line.

[Effect of idea]

In this invention, a notch is formed in the side of the main body of the suspension device that communicates with the groove in which the rail is inserted.
When the door is opened or closed, the side surface of the notch receives the force applied laterally to the rail, allowing the door roller to always be kept in a predetermined position. Therefore, the door roller runs smoothly, and since the door roller does not come off, there are fewer breakdowns.
