Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to the opening/closing structure of a door such as a sliding door, and more specifically, the present invention relates to an opening/closing structure for a door such as a sliding door. In addition to increasing its ease of use by rotating it,
This invention relates to a technology that uses a simple configuration to avoid interference by the front door when opening and rotating the door on the back side when opening and rotating the door relative to the running rail. .

[Background Art] Conventionally, a door such as a sliding door that runs on the upper rail only runs on the upper rail, and its function is a single function. It is not possible to open and rotate the door approximately perpendicular to the upper rail in the vicinity of the door, making it difficult to use such a door as a partition. Therefore,
Various configurations have been proposed in which a door such as a sliding door is opened and rotated so as to be approximately perpendicular to the upper rail in its closed position. However, the front door interferes with the opening and rotation of the rear door, making it difficult to open and rotate the rear door.

[Purpose of the invention] The present invention was made in view of the above-mentioned problems, and its purpose is to make a door such as a sliding door so that it almost intersects with the running rail in the closed position. Although the opening rotation increases the ease of use, the rear door can be easily opened and rotated without interference from the front door, and the configuration can be simplified. Our goal is to provide a structure that allows doors to open and close.

[Disclosure of the invention] The door opening/closing structure of the present invention has a plurality of door bodies 3 arranged side by side in the front and back direction in the thickness direction, and each door body 3 is connected to at least upper and lower running tools a on the door edge side. a
The respective door bodies 3 are installed so that they can run freely on the respective running rails R, and the respective door bodies 3 are connected to their running tools a, a.
The receiver 4 is configured to be able to open and rotate approximately perpendicularly to the running rail R through the support body 4, and the door tip of the door body 3 at the front in the thickness direction comes into contact with the receiver 4 to determine the closed position. It is constructed so that it can freely rotate rearward, and when this receiver 4 is rotated backward and retreated, it travels to the position created by this retreat and is substantially orthogonal to the traveling rail R at this location. It is characterized in that it is a positioning tool that determines the opening rotation position at which the rear door body 3 can be opened and rotated without interference with the front door body 3 that has been rotated to open. With this configuration, the above object has been achieved. In other words, the door body 3 can be opened and rotated approximately perpendicularly to the running rail R, increasing the usability of a door such as a sliding door. When the receiving body 4 that abuts to determine the closed position is rotatable rearward about the vertical axis, and the receiving body 4 can be rotated backward and retracted,
The rear door body 3 can be opened and rotated without interference from the front door body 3 which has traveled to the position created by this evacuation and has been rotated to open approximately perpendicular to the traveling rail R at this point. By using a positioning tool that determines the opening rotation position that can be moved, when the receiver 4 is rotated backward and evacuated, the evacuated receiver 4 is moved to the rear door body 3. Therefore, the front door body 3 is moved to the location created by the retraction of the receiver 4, and then the front door body 3 is opened and rotated so as to be approximately perpendicular to the running rail R. In this case, the rear door body 3 is positioned at a position where its opening rotation is not interfered with by the front door body 3, and the front door body 3
Effectively utilizes the receptor that positions the closed position of the
By utilizing this simple configuration, the rear door body 3 can be easily and reliably opened and rotated.
This allows it to be done without causing any damage.

Embodiments of the present invention will be described in detail below based on the drawings.

FIG. 1 shows a schematic front view, in which a plurality of doors 7, 7 are installed on the upper rail 1 and lower rail 2 as running rails R so that they can run freely. The number of 7s is 1 even if there are many
It may be one piece. Two guide grooves 8 are formed in each of the upper rail 1 and the lower rail 2. Door body 3
Running shafts 5, 5 as running implements a forward in the closing direction are protruded from the upper and lower ends of the door edge side, and the lower running shaft 5 is connected to the guide groove 8 of the lower rail 2 as a pivot 5a.
It is fitted in so that it can run freely. Runner rollers 9 are rotatably provided on the upper running shaft 5 via a running block, and these runner rollers 9 are connected to the upper rail 1.
It is mounted on the receiving surface of the car so that it can be moved. Travel receiving pieces 11, 11 are hung over the entire length on the front and back sides of the upper rail 1 so as to be able to guide travel.

The vertical frame 13, which is an example of the receiver 4 that determines the closing position of the door body 3, which is built so that the door body 3 can travel freely, is pivoted freely around the vertical axis via the hinge 14. The vertical frame 13 can be freely retracted from the running area of the door body 3. and vertical frame 1
3 is evacuated, that is, the door body 3 is made to be freely movable to the inner part beyond the closed position of the door body 3 in the closing direction. A catch 16 as an example of the opening rotation holding means 6 is provided above in this deep part, and the running shaft 5 on the door main body 3 that has been moved to the deep part is fitted into the catch 16 and held. By holding the running shaft 5 in the door direction, the door body 3 can be opened and rotated substantially perpendicularly to the upper and lower rails 1 and 2. In such a case, the pivot 5a rotatably provided at the lower end of the lower running shaft 5 is non-rotatably engaged with the guide groove 8 of the lower rail 2, and the pivot 5a is rotatably provided at the lower end of the lower running shaft 5.
After the tip of a moves away from the vertical frame 13, it comes into contact with the wall surface and its position is determined, as if it were the lower traveling shaft 5.
In this way, the upper and lower running shafts 5, 5 are held so that the door 7 can be stably opened and rotated.

A notch b corresponding to approximately one sheet of the door body 3 is provided in the traveling receiving pieces 11, 11 on the side of the vertical frame 13 of the upper rail 1, and a cover plate 31 is provided in the notch b to close it.

In this way, by forming the notch b in the upper rail 1, the door body 3 can be rotated and removed, and the door body 3 can be opened and rotated approximately perpendicular to the upper rail 1, making it look like a sliding door. It is simple to increase the usability of the door, make effective use of the running tools a and a at the door tip, and provide a notch b in the upper rail 1 that allows the door body 3 to escape from the upper rail 1 when it rotates to open. The structure is fine. Furthermore, the notch b is provided with a cover plate 31 for closing it, thereby enhancing the appearance.

As shown in FIG. 3, the lid 31 is rotatably attached at its upper edge so that the lid plate 31 that closes the notch b hangs down under its own weight, and when the door 7 is opened. It was made so that it could be lifted up and rotated like a noren.

When the vertical frame 13 serving as the receiver 4 is rotated backward, it travels to the position created by this retreat, and opens and rotates at this location to be approximately orthogonal to the running rail R. This is a positioning tool for determining an opening rotation position at which a rear door body 3 can be opened and rotated without interference with the moved front door body 3. However, as shown in FIG. 7b, when the receiver 4 is rotated rearward and evacuated, this evacuated receiver 4 is attached to the rear door body 3.
Therefore, the front door body 3 is moved to the location created by the retraction of the receiver 4, and then the front door body 3 is opened and rotated so as to be approximately perpendicular to the running rail R. In this case, the rear door body 3 is positioned at a position where its opening rotation is not interfered with by the front door body 3, and the rear door body 3 can be easily and reliably opened and rotated without damaging the door body 3. I can do it. Such a receiver 4 has a thickness T that is approximately 1/3 of the width W of the vertical stile 17 forming the opening,
Further, it has a length L that is approximately 2/3 of the vertical stile 17. As shown in FIG. 8, if a few spacers 18 are provided at the tip of the receiver 4, the door 7 at the rear can be opened and rotated even more easily.

In the embodiment, the opening rotation holding means 6 holds the running shaft 5 with a substantially C-shaped catch 16, but the running shaft 5 may be held from its end. The lower traveling shaft 5 may also be held like the upper traveling shaft 5.

Further, in the embodiment, a catch 16 for holding the running shaft 5 is provided, but the catch 16 may be omitted, and in short, any door body 3 can be opened and rotated perpendicularly to the running rail R. Bye.

[Effects of the invention] In summary, the present invention allows the door body to open and rotate approximately perpendicular to the running rail, increasing the usability of doors such as sliding doors, while at the same time improving the usability of doors in the front direction in the thickness direction. When the receiver that the door tip of the door body comes into contact with and determines the closed position is configured to be able to freely rotate backwards around the vertical axis, and the receiver is pivoted backwards, the position created by this retreat. An opening rotation position where the rear door body can be opened and rotated without interference from the front door body, which has been traveled up to this point and rotated to open approximately perpendicular to the running rail. Since it is used as a positioning tool to determine the position of the door, when the receiver is rotated backwards and evacuated, this retracted receiver becomes the positioner for the rear door body, and therefore, the retracted receiver becomes the positioner for the rear door body. If the front door body is run at a location where the front door body is moved, and then the front door body is opened and rotated approximately perpendicular to the running rail, the rear door body will be moved by the front door body as the opening rotation is made. It is positioned in a position where it will not be interfered with, and effectively utilizes the receiver that positions the closing position of the front door body.With a simple configuration that utilizes this, the opening rotation of the rear door body can be easily and reliably done. This has the advantage that it can be done without damaging the door itself.
