This invention relates to a technique for increasing the ease of use by rotating the device, simplifying the configuration for doing so, and enhancing the appearance while doing so.

[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. The door cannot be opened and rotated approximately perpendicularly to the upper rail in the vicinity of the door, making it inconvenient 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 substantially perpendicular to the upper rail in its closed position, but this poses a problem in that the structure becomes complicated.

[Purpose of the invention] The present invention was made in view of the above problem, and its purpose is to open a door such as a sliding door so that it is approximately perpendicular to the upper rail in the closed position. To provide a door opening/closing structure which can be relatively simple in construction and can enhance the appearance, while increasing the ease of use by rotating.

[Disclosure of the invention] The door opening/closing structure of the invention runs the door main body 3 via upper and lower running tools a at least on the door end side along an upper rail 1 which is open at the bottom and has a substantially inverted U-shaped cross section. A retractable receiver 4 is provided, which can be freely configured and retracted to determine the closing position by which the tip of the door body 3 that is opened and closed by running along the upper rail 1 comes into contact with it, and the closing position of the door body 3 is closed. The door main body 3 is configured to be able to freely travel to the inner part beyond the direction of construction, and the upper and lower running tools a, a of the door tip of the door main body 3 are held in this inner part, and the door main body 3 is moved to the upper rail 1.
An opening rotation holding means 6 is provided to open and rotate the door substantially perpendicularly to the door body 3.
A notch b for approximately one piece of the door body 3 is provided in the upper rail 1 to allow the door body 3 to escape from the upper rail 1 when the door body 3 is opened and rotated, and a cover plate 31 that closes the notch b is released. It is characterized by being provided in such a way that it can be opened freely via a flexible locking means R, and by configuring it in this way, the above object has been achieved. In other words, the receiver 4 that determines the closed position of the door body 3 is retracted, the door body 3 is moved to the inner part, and the opening rotation holding means 6 provided in the inner part is used to open the door tip of the door body 3. A cutout b for approximately one piece of the door body 3 of the upper rail 1 holds the upper and lower running tools a, a.
By rotating the door body 3 and escaping, the door body 3 can be opened and rotated to be approximately perpendicular to the upper rail 1, which increases the usability of the door like a sliding door. By effectively utilizing the running tools a and a at the tip, and when opening and rotating the door body 3,
Cut out the notch a to escape from the upper rail 1.
Moreover, by providing a cover plate 31 to close the notch b, the notch b is closed and the appearance is enhanced, and the cover plate 31
has a locking means R, and since the closed cover plate 31 can be closed by the locking means R, the cover plate 31 will not be opened unexpectedly or shake, and can be integrated with the upper rail 1. The appearance can also be improved in this respect.

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 the lower rail 2 so as to be freely movable, but the number of doors 7 may be many or one. Two guide grooves 8 are formed in each of the upper rail 1 and the lower rail 2. Running shafts 5, 5 as running tools a forward in the closing direction are protruded from the upper and lower ends of the door tip side of the door body 3, and the lower running shaft 5 is inserted into the guide groove 8 of the lower rail 2 as a pivot 5a. It is fitted in such a way that it can be moved freely. Runner rollers 9 are rotatably provided on the upper running shaft 5 via a running block, and these runner rollers 9 are mounted on the receiving surface of the upper rail 1 so that they can run. 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 built so that the door body 3 can move freely in this way, is rotatably pivoted via a hinge 14. The frame 13 is made retractable from the running part of the door body 3. And it is made to be able to run freely to the part where the vertical frame 13 is evacuated, that is, to the inner part beyond the closing position of the door body 3 in the closing direction. In this deep part is a catch 1 as an example of the opening rotation holding means 6.
6 is provided above, and the running shaft 5 on the door body 3 that has been run to the back is fitted and held in the catch 16. By holding the running shaft 5 in this way, the door body 3 can be moved up and down. It is designed to be able to open and rotate approximately perpendicular to the 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 tip of the pivot 5a is connected to the vertical frame 1.
3 has been evacuated, its position is determined by abutting against the wall surface, and it is in a state as if it were holding the lower traveling shaft 5. In this way, the upper and lower traveling shafts 5,
5 is 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. The cover plate 31 can be locked in the closed position of the cover plate 31 by a locking means R such as a magnet type or a penetration type which will be described later.
Moreover, this lock can be easily released.

In this way, by forming the notch b for approximately one piece of the door body 3 in the upper rail 1, the door body 3 can be rotated and escaped so that the door body 3 is approximately orthogonal to the upper rail 1. A notch b that opens and rotates to increase the usability of a door such as a sliding door, makes effective use of the running tools a and a at the door tip, and allows the door body 3 to escape from the upper rail 1 when the door body 3 rotates to open. A simple configuration of providing the upper rail 1 is sufficient. Moreover, by providing a cover plate 31 for closing the notch b, the notch b is closed and the appearance is enhanced, and the closed cover plate 31 can be closed by the locking means R, and the cover plate 31 can be unexpectedly closed. It does not open or sway, and is integrated with the upper rail 1 to enhance its appearance.

As shown in FIG. 3, the cover plate 31 is
The door 7 is rotatably attached at a hinge portion of the upper edge so that the lid plate 31 that closes the notch b hangs down under its own weight, and the locking means R is unlocked, and then the door 7 is opened by rotation. It was made so that it could be lifted and rotated like a noren curtain.

As the locking means R, as shown in FIG.
Place the magnet receiving piece 34 on the cover plate 31 side with double-sided tape 3.
5, and attach the magnet case 37 with the magnet 36 attached to the upper rail 1 side with double-sided tape 35.
When the door 7 is rotated and closed using such a magnetic locking means R, the cover plate 31 can be magnetically locked. Also, as other locking means R,
As shown in FIGS. 9 and 10, a through hole 39 is slidably inserted into the lower space 38 of the running receiving piece 11 of the upper rail 1, and the pin 4 is made to protrude from the through hole 39.
0 is formed in the running receiving piece 11 of the upper rail 1.
1, and by sliding the through hole 39 with the pin 40 and inserting it into the receiving recess 42 at the bottom of the cover plate 31, which is hanging down due to its own weight, the cover plate 31 can be opened and deflected. There are things that suppress it. Also, the 11th
As shown in the figure, at the hinge between the upper rail 1 and the lid plate 31, the lid plate 31 is lowered by its own weight,
When the protrusions 43 come into contact with each other, the cover plate 31 becomes unable to rotate, and by pushing up the cover plate 31 by hand or the like and disengaging the protrusions 43, 43, the cover plate 31 is removed. 31 opening rotation is possible, and
As shown in FIGS. 12a and 12b, the projecting edge 4 is
Various design changes are possible, such as a configuration in which the projecting edge 44 prevents the opening rotation of the hinge portion of the cover plate 31, or a configuration in which such a projecting edge 44 can be protruded and retracted.

In addition, in the embodiment, the receiver 4 is used as the vertical frame 13, but the receiver 4 does not have to extend along the entire length in the vertical direction of the door body 3 like the vertical frame 13, and may be short. It may be provided within the upper rail 1 and lower upper rail 2 of
Its configuration can be modified in various ways.

Further, in the embodiment, the opening rotation holding means 6 holds the running shaft 5 by inserting it into the substantially C-shaped catch 16, but the running shaft 5 may be held from the end thereof. The lower traveling shaft 5 may also be held like the upper traveling shaft 5.

Further, in the embodiment, the receiver 4 is rotated and retracted, but the retracting may also be performed by sliding.

[Effects of the invention] In summary, the present invention is such that the door body is configured to be able to run freely along an upper rail that is open at the bottom and has a generally inverted U-shaped cross section, via upper and lower running tools at least on the door edge side. A retractable receiver is provided to determine the closing position when the tip of the door body, which is opened and closed by running along the rail, comes into contact with the door body. The upper and lower running tools of the door tip of the door body are held in this inner part, and the door body is opened and rotated approximately perpendicularly to the upper rail to open and rotate. A notch for approximately one piece of the door body is provided on the upper rail to allow the door body to escape from the upper rail when the traveling tool is held by the opening rotation holding means and the door body is opened and rotated. Since the receiver that determines the closing position of the door body is retracted, the door body is moved to the back, and the opening rotation holding means provided at the back allows the upper and lower parts of the door tip of the door body to be moved up and down. The door body can be opened and rotated approximately perpendicular to the upper rail by holding the running tool and rotating the door body through the approximately one-piece notch in the upper rail. The idea is to increase the usability of doors such as sliding doors, while also making effective use of the running gear at the door tip, and providing a notch in the top rail that allows the door to escape from the top rail when it rotates to open. The structure is simple, and since the notch is provided with a cover plate to close it, the notch can be closed to enhance the appearance, and the cover plate has a locking means, so that the closed cover plate can be locked. Since the lid plate can be closed by means of the above-mentioned means, the lid plate will not be accidentally opened or shaken, and the lid plate can be integrated with the upper rail, which also has the advantage of improving the appearance.
