Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention provides a method for bringing at least two doors into an opening of a cabinet or the like into a two-dimensional closed state by abutting each other at their inner ends, Regarding flat sliding doors for insets or outsets in which one door is moved from this state so that it overlaps the front side or back side of the other door to create a stacked open door state, In particular, the present invention relates to a moving device for supporting rollers in the door.

[Conventional technology]

Conventional so-called sliding doors have a step in the thickness direction of the door between the doors, which detracts from the aesthetics of the design. Therefore, the above-mentioned flat-close sliding door that does not have a step is attracting attention. However, due to the structure of the existing door, unless there is a gap between the butt ends of both doors, the doors cannot be opened or opened, resulting in stacking of the doors, so it is necessary to make the door completely closed. There are various problems in terms of use, manufacturing, and cost, such as the inability to open and move the doors without chamfering the back surfaces of the butting ends of both doors into an inclined state.

Therefore, in an attempt to solve the above problem, the applicant has already provided two running bodies at both the upper and lower ends of the left and right doors, at the inner and outer ends of the door width direction, and on the other hand, the door mounting On the opposing surfaces of the upper and lower walls of the frame, there is a straight part at the center, sloped parts curved backward on both left and right sides of the straight part, and guide parts curved backward on both left and right sides of the straight part. One upper wall door rail consisting of one upper wall door rail and one lower wall door rail are installed side by side, and the running bodies at both the inner and outer ends in the door width direction are
By being engaged with the guide portion and the inclined portion of both door rails, the left and right doors are brought into a planar closed state with their respective inner edges butted against each other, and one door is connected to the other door. A planar closing sliding door device configured to be closed in a stacked state at the front or back is proposed.

According to the above-described door device, when both doors are closed in a plane, both door rails are covered by the doors, so that they are not exposed to the outside, and the design is excellent. Although it is certainly effective in that it is possible to make a completely closed door without cutting out the butting end of the door, and the structure can be simplified and manufactured at a low cost, the above door device is Since the weight of the door is carried by the traveling body, even if the traveling body is formed of rollers or rollers, the opening and closing operations of the door become heavy, and therefore, there is a drawback that the door is not suitable for particularly large and heavy doors. .

Therefore, it has been proposed to provide two supporting running rollers that receive the weight of the door, separately from the running body, at both the upper and lower ends of the door, and at both the inner and outer ends in the width direction of the door.

The support running roller is conveniently supported for moving and opening/closing the door, and is pivotally supported by a support shaft provided perpendicular to the door width direction, and is provided so as to roll on the flat part of both door rails in the door width direction. There is.

However, when the above support running roller is provided,
When the door is opened and closed, when the running body is pulled out from the guide part and the inclined part of both door rails to the straight part, and from the straight part to the guide part and the inclined part, and then pushed in, the support running roller is rotated. not the direction,
The door slides on the flat part of the rail in a direction almost perpendicular to the direction of rotation, so when opening and closing the door by moving it in the width direction, the door slides smoothly.
Although it is light and nimble, when opening and closing the door, frictional resistance between the support running roller and the rail increases the door opening/closing operation, and if the support running roller is made of metal, the roller and rail may wear out. As a result, the door may not open and close smoothly, and if rubber rollers are used, twisting force may be applied to the rollers, damaging them and causing malfunctions.

[Problem that the invention seeks to solve]

The present invention is an attempt to solve the above-mentioned problems, and is a planar closing device comprising two support running rollers and two guide running bodies at both the upper and lower ends of the door, at the inner and outer ends in the width direction of the door. At the door,
When the guide section of the upper wall door rail and the lower wall door rail is engaged with and disengaged from the guide section when the door is opened or closed, the door can be transferred from the supporting roller to the guide section and carried. By providing a push-up guide portion of the guiding traveling body, when the door is opened and closed, the weight of the door is supported by the supporting traveling rollers, so that the door can be opened and closed smoothly and easily. ,
When opening and closing the door, the weight of the door is supported by the guide running body to prevent sliding between the supporting running rollers and the rails, allowing the door to open and close easily, and reducing wear on the supporting running rollers and the rails. Its purpose is to prevent damage and improve durability.

[Means for solving problems]

That is, the present invention provides two support running rollers, two guide running bodies, and two guide running bodies provided at the upper and lower ends of the left and right doors, respectively, at the inner and outer ends in the door width direction. A flat rail part that rollably engages the support running roller so that the door can be opened and closed while supporting the door, and a straight part in the center that engages the running body and can guide both doors so that they can be opened and closed. , is formed by an inclined part curved backward on both the left and right sides, and a guide part curved backward on both left and right sides of the center part of the straight part, and is opposed to the upper and lower walls of the door mounting frame. one upper wall rail and one lower wall rail, and guide running bodies at both inner and outer ends in the door width direction are engaged with the guide portion and the inclined portion of both door rails.
