Description

[Detailed description of the invention] <<Industrial application field>> The present invention is a system for mutually connecting at least two doors (inset type) in which the doors are housed in a mounting frame that forms an opening in a cabinet, etc. of,
An inset in which the doors are brought into a two-dimensional closed state by butting against each other at their inner edges, and from this state, one door is moved to the back side of the other door so that they overlap, resulting in an open state in which the doors are stacked. This invention relates to a plane closing sliding door device for use in a flat sliding door.

Conventional general sliding doors create a step between the doors in the door thickness direction, which detracts from the aesthetics of the design, so the above-mentioned flat-close sliding doors are increasingly being used, but there are currently Due to the structure of the door, unless a gap is provided between the butt ends of both doors, the doors cannot be opened or opened so that they are stacked on top of each other, so it is not possible to completely close the door. As shown in Utility Model Application Publication No. 58-75877, there are various problems in use, manufacturing, and cost, such as the fact that opening cannot be moved unless the back surfaces of the butting ends of both doors are chamfered into an inclined state. .

In other words, the content of the above-mentioned known example is that running wheels are provided at the top and bottom of the sliding door, and these wheels are fitted into the running guide grooves of the upper and lower stile in the mounting frame so that they can run freely, and wheels are installed on the left and right sides of the running guide grooves. A pair of diagonal guide grooves are arranged in series, and when using this, the running wheels are guided by the diagonal guide grooves when pushing one sliding door to the back from the closed state. If the pushing direction is not exactly parallel to the direction of the diagonal guide groove, the sliding door will not be able to be pushed in smoothly.Furthermore, in order to enable the sliding door to run diagonally as described above, The mating ends of sliding doors must be chamfered diagonally, making this process quite troublesome.

The present invention is an attempt to solve the above-mentioned conventional problems, and it is designed to appropriately install two running bodies such as rollers at both the upper and lower ends of the left and right doors, at the inner and outer ends of the door width direction. On the other hand, on both the upper and lower walls of the door mounting frame, one upper wall door rail and one lower wall door rail are installed in parallel on the opposite surfaces. When the door is closed flat, both door rails are covered by the door, so they are not exposed to the outside.
Not only can the design be excellent, and a completely closed door with no gaps can be created without cutting the butt ends of the door, but also when the door is initially opened and closed, To make it possible to simply pull or push the door in the front-rear direction perpendicular to the door without moving the door diagonally, thereby improving usability and achieving smooth opening and closing, and furthermore, to facilitate the installation of a traveling body. The object is to provide a plane closing sliding door device for insets that can be simplified and manufactured at low cost by having one rail for each of the upper and lower sides.

Hereinafter, the present invention will be described in detail based on the illustrated embodiment. As shown in FIGS.
By abutting the doors, the door is closed in a two-dimensional state, with almost no gaps remaining between the upper wall 3a, the lower wall 3b, and the inner surfaces of the left and right side walls 3c, 3d of the door mounting frame 3 in a cabinet, etc. They are formed in the same size with storageable vertical and horizontal dimensions, and are located at the upper and lower ends of each
