[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a door opening / closing device in which a door which can be opened and closed by a slide can be opened and closed by a swing as required. The present invention relates to a door opening / closing control device that prevents a door from opening and closing with a swing.

[0002]

By BACKGROUND ART slide, also the automatic door can be opened and closed is known by the swing. This is the figure
As shown in FIG. 6, a suspension frame is suspended via a pulley on a blind upper rail, and a door 1 is suspended from the suspension frame. The forward and reverse rotations of the driving device are performed via a belt and a pulley. The left and right doors 1 are opened and closed by sliding along the doors 2 as shown in FIG.

[0003] Toka when carrying a large Kina luggage, such as when an abnormal situation, such as a fire occurs, when you need a large frontage, as shown in FIG. 6 (b), the door 1
When the door 1 is pushed outward, the door 1 is disengaged from the engaging portion with the suspension frame 8 and swings with the pivoting fulcrum 5 as a fulcrum. I do. Even when the door 1 is kept open, the door 1 is slid to the position of the pillars 3 on both sides, so that a frontage that is twice as large as that of a normal door can be obtained.

[0004]

However, in a state where the door 1 can be normally opened and closed by sliding, when the door 1 is pushed out as shown in FIG. 6B, the fitted door 2 always swings. It is necessary to keep such a state.

However, in such a state,
When leaning against the door 2 or a large wind pressure is applied, there is a problem that only the door 2 is opened as shown by a chain line in FIG.

According to the present invention, in a normal state in which the door is opened and closed by sliding, the door does not open with the ink.
It is an object of the present invention to obtain a device that opens in conjunction with only the opening and closing of a door swing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. A horizontal upper rail 11 is provided inside the blind 7, and a suspension frame 8 is suspended on the upper rail 11 via slides 10, 10 and pulley holding plates 9, 9 so as to be movable by sliding. I have. As shown in FIG. 4, the door 1 is suspended from the swing fulcrum 5 at one end and the engaging portion 16 at the other end of the suspension frame 8. That is,
The turning fulcrum 5 has a vertical turning shaft 12 rotatably penetrating through the suspension frame 8 with a bearing 15 (does not move up and down). The lower end of the turning shaft 12 is connected to the upper frame 25 of the door 1. An unlocking lever 13 is integrally fixed to the upper end of the pivot 12 integrally with the door support 14 which is fixed. The unlocking lever 13 has a rectangular plate shape slightly protruding from the hanging frame 8 in the direction of the door 2, and rotates integrally when the door 1 swings. The engaging portion 16 has, for example, an L-shape, engages with the engaging hole 17 of the upper frame 25, and comes off when swinging.

As shown in FIGS. 1 and 3, the fitting door 2 is rotated by a swing fulcrum 6 provided on the blind 7 and a swing fulcrum (not shown) provided on the floor. You can only do it. Further, inside the blind 7, a turning prevention unit 1 for preventing a swing of the fitted door 2 is provided.
8 are provided. A lock pin 24 is fixed to the tip of an elongated holding plate 19 in a downward direction, and the lower end of the lock pin 24 penetrates a guide hole 27 provided in the eyelet 7 so that the turning door 18 of the fitting door 2 Locking hole 2 provided in upper frame 28
6 Below the other end of the holding plate 19, a downward U-shaped pin receiving plate 21 is provided.
The pin holding plate 22 provided on the eyelet 7 and the shaft pin 23 passing therethrough make the holding plate 19 rotatable. The holding plate 19 has a tapered portion 20 at a portion facing the hanging frame 8. The tapered portion 20 and the unlocking lever 13 have a slight gap when the door 1 is opened and closed by sliding. doing.

In the above-described configuration, during normal opening / closing by sliding, the door 1 is hung below the suspension frame 8 by the turning fulcrum portion 5 and the engagement portion 16, The door 2 is located immediately below the blind 7 and has a locking hole 26 in the upper frame 28.
, The lock pin 24 of the turning prevention unit 18 is lowered and engaged. Therefore, the door 2 cannot be rotated by the swing.

When a large frontage is required, the door 1 is pushed out as shown in FIG. Then, the door 1 is disengaged from the engaging portion 16 and the engaging hole 17 and slightly swings around the turning fulcrum 5 as shown in FIGS. 2 and 5. With the opening of the door 1 by the swing, the unlocking lever 13 also rotates together with the door 1 via the turning fulcrum 5, and the unlocking lever 13 is tapered by the pressing plate 19 of the turning preventing portion 18. 20 hits. When the door 1 is further rotated, the unlocking lever 13 presses into the lower side of the tapered portion 20 and pushes up the pressing plate 19, so that the pressing plate 19 rotates about the shaft pin 23 as a fulcrum to raise the lock pin 24. Let it. Therefore, the engagement between the lock pin 24 and the locking hole 26 is released. When the door 1 is further pushed out, the door 1 is pivoted on the pivot point 5, and the locked door 2 is
While being pushed out by the door 1, the door 1 and the swivel door 2 are pivoted by the swing with the swing fulcrum 6 as a fulcrum, and are simultaneously opened by the swing. The holding plate 19 is fitted with the upper frame 28 of the door 2
Since they are almost the same length, opening the door 1 by swinging
Engagement door 2 is open and closed at any time
Opened by swing.

After the door has been used by the double width, the door 2 and the door 1 are swung in the opposite directions to return to the original position.
3 is disengaged from the holding plate 19, the holding plate 19 is lowered by its own weight, and the lower end of the lock pin 24 is again engaged with the locking hole 26 of the fitting door 2.
And the turning prevention unit 18 returns to the normal state with the fitted door 2. The door 1 is also normally suspended and fixed below the suspension frame 8 by the engagement of the engagement holes 17 and the engagement portions 16.

[0014]

[Effects of the Invention] (1) Since the present invention is configured as described above, even when wind pressure is applied or leans, only the door 2 swings and does not open. (2) The holding plate 19 is approximately the same length as the upper frame 28 of the door 2
Because there is, the opening by the swing of the door 1 is by sliding
In any position of opening and closing, the door 2 can swing at the same time.
More open and restricted by the swing open / close position.
And not. (3) Push the door 1 and open it with a swing
And the turning fulcrum 5 of the door 1 and the unlocking lever 13 are integrally turned.
And the unlocking lever 13 is pushed by the unlocking lever 13.
Pushing up the plate 19, the engagement between the turning prevention part 18 and the door 2
The door 1 is moved by a predetermined amount and then
There is no need to perform a fixed amount of movement and unlock work.
The operation is simple. (4) When the door is not used as an automatic door, such as at night, only the lock mechanism is provided on the door, and there is no need to provide the door on the door. (5) The structure is simple, inexpensive and safe.
