Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door opening / closing device in which a sliding opening / closing door can be opened / closed by swinging by adding a simple device to the door without lowering the door.

[0002]

2. Description of the Related Art Generally, a door that can be opened and closed by sliding and swinging as shown in FIG. 7 is known. this is,
The opening / closing door 10 and the fitting kill door 11 are provided.
In the device that opens and closes between the pillars 14 by the traveling wheels 19 while being suspended from the upper rail 16 in the seamless 15, the swing fulcrum 1 by swinging the opening / closing door 10 as necessary.
When the door 2 is opened with the fulcrum 2 as the fulcrum, the fit-and-kill door 11 is also opened with the fulcrum fulcrum portion 13 as the fulcrum, and a width twice as wide as the opening width by sliding is obtained.

Whether the opening / closing door 10 is completely closed by sliding or is completely opened,
In some cases, even if the door is in the middle of opening, if the opening / closing door 10 is pushed out, it is fitted and killed, and the door 11 is opened by swinging, and the opening / closing door 10 can be slid to the fully opened position while being opened.

As described above, when the swing door can be opened and closed at any position, the open / close door 10 must swing while supporting the entire load at the upper swing fulcrum portion 12, so the door tip is inevitably lowered. There's a problem. In order to solve this problem, conventionally, the swing axis of the upper swing fulcrum portion 12 is thickened to be inserted into the standing frame, or a cam is provided so that the door tip is gradually lifted as it swings, A method has been adopted in which the lower swing fulcrum portion 12 is pressed against a cam or the like so as to have resistance so as not to move during the swing.

[0005]

However, the conventional apparatus is not sufficient to prevent a heavy door from falling down due to its simple structure, and it is inefficient to completely prevent the door from falling down. 15 The internal mechanism became complicated, and in particular, it was almost impossible to completely prevent the door from falling down with a door without a vertical frame.

According to the present invention, by simply adding a simple device to the upper frame 50 and the suspension frame 18 of the sliding door 10, it is possible to completely eliminate the descent of the door when swinging, even if the door is heavy. An object is to provide a door opening / closing device.

[0007]

According to the present invention, the opening / closing door 10 is suspended by the swing shaft 23 and the latch 24 on the suspension frame 18 to enable the slide opening / closing, and the swing shaft 23 can be used as the fulcrum to open / close the swing. In the door, the sliding plate 30 is provided on the suspension frame 18 so as to be movable by a predetermined distance, and the fixing member 22 is provided between the suspension frame 18 and the sliding plate 30 when the opening / closing door 10 is fully opened. A holding means for holding and a swinging plate 64 that is rotatably connected to the sliding plate 30 and restricts movement and fixing of the hanging frame 18 and the sliding plate 30 to each other, and this swinging plate 64. The door opening / closing device is characterized by comprising a locking means for holding and releasing the holding means by setting a rotational position of the holding means.

[0008]

[Action]

(1) Opening / Closing by Sliding When the opening / closing door 10 slides, the stop notch 46 contacts the fixing member 22, and the hanging frame 18 moves slightly together with the opening / closing door 10. Then, the holding part 49 is lifted and the fixing member 22 is held. At this time, since the lower end surface of the rocking plate 64 is on the upper end surface of the locking plate 28, the locking plate 28 moves together with the opening / closing door 10 while being in contact with the lower end of the rocking plate 64. When the opening / closing door 10 is moved again together with the suspension frame 18 while the locking plate 28 is raised, the holding member 49 releases the holding of the fixing member 22, and the opening / closing door 10 moves to the left. As long as the locking plate 28 is raised, it is opened and closed by sliding. (2) Opening / Closing by Swing Before opening by swinging, the opening / closing door 10 is moved to the right end, and the knob 29 causes the rocking plate 64 to descend downward by the locking plate 28. Then, the shaft pin 65
Fits into the locking recess 67 and locks. In this engaged state, the suspension frame 18 and the sliding plate 30 cannot move and cannot be opened / closed by sliding. Here, when the opening / closing door 10 is pushed out to the side and opened by a swing, the hanging frame 18 and the sliding plate 30 are fixed by sandwiching the fixing member 22, so that the opening / closing door 10 is fixed to the swing shaft 23 and the steady rest projection. It is opened by swinging around 55 and the fulcrum.

The rocking plate 64 is slightly lifted by the locking plate 28, and then is lowered downward by the coil spring 80 as shown in FIG. At this time, the shaft pin 65 is fitted into the escape recess 69 side and then fitted into the locking recess 67 to be locked. In this state,
Even if the opening / closing door 10 is moved leftward, the suspension frame 1
8 and the sliding plate 30 cannot move due to the engagement of the shaft pin 65 and the locking recess 67, and cannot be opened and closed by sliding.

When the opening / closing door 10 is pushed out to the side and opened by a swing, the hanging frame 18 and the sliding plate 30 are fixed by holding the door stop 22.
Only the swing shaft 23 and the steady rest projection 55 are used as fulcrums to open by swinging. Since the steady rest projection 55 is fitted in the guide opening guide notch 57, the steady rest projection 5
If 5 rotates even a little, the movement to the left and right is restricted and the deviation is prevented.

In the state shown in FIG. 3, after the opening / closing door 10 is closed again by swinging, the locking plate 28 is opened by the knob 29.
When it is turned counterclockwise, the taper surface 81 of the rocking plate 64 is pushed up while sliding on the upper end of the locking plate 28 to return to the state of FIG.

When the locking plate 28 is rotated by the knob 29 when the slide is opened and closed as shown in FIG.
Since the shaft pin 65 is engaged with the long hole portion 68, therefore, the swing cannot be performed on the way.
