Description

[Detailed Description of the Invention] In the present invention, the door is normally opened and closed by sliding along the insert door, and if necessary, by pressing the door, the door can be swung together with the insert door. te2
This invention relates to a door opening/closing device that doubles the width of the door.

In general, automatic doors come in two types: sliding type and swing type. The swing type requires space for the door to swing, but the sliding type does not require that space, and the sliding type has advantages such as being able to enter and exit from both sides, so it is currently used more than the swing type. . However, sliding type doors are usually fitted with a sliding door that is the same width as the door.

Therefore, when carrying in or out of machinery larger than a door, it is necessary to remove the door and the inset door, but this removal work is often only possible for service personnel, and it takes a long time to remove it. There was a problem that it was necessary. Also,
Automatic doors are installed in places where an unspecified number of people gather, so if a fire or earthquake occurs and the automatic doors do not open, it is easy to panic. Even if a disaster occurs, it is desirable to easily open the door and the jammed door to secure as wide a frontage as possible so that evacuation guidance can be conducted as soon as possible.

The present invention was made with the aim of solving these conventional problems.The door and the sliding door are equipped with a turning mechanism, so that the door can normally be opened and closed in a sliding manner, and can be opened and closed as needed. By pressing the door with your hand, both the door and the fitted door can be opened in a swinging manner.

An embodiment of the present invention will be described below with reference to the drawings.

First, to explain the general structure of an automatic door, in Fig. 1, 33 is a door that is fixedly attached to the ceiling of an entrance, etc., and there is a door between this door 33 and the floor that can be opened and closed by sliding. When the door 9 is placed on the inside and the fixed closing door 32 is on the outside, and when the door 9 is closed, the door 9 and the closing door 32 touch each other at their respective ends A and D. It is provided in a state where it partially polymerizes.

are fitted to form the door hinge 12 as a turning fulcrum. Also, on the outer surface of the hanging frame 8, the fitted door 32
A ratchet receiving piece 13 is fixed to the end portion on the side away from the ratchet receiving piece 13, and a pin 14 is provided on the ratchet receiving piece 13 facing downward to form an engaging portion 14.

A vertical connecting rod 17 is rotatably supported on the door 9 at a position facing the engaging portion 14 by a bearing 23 of the door 9. A crank latch 16 is fixed to a portion of the connecting rod 17 that protrudes from the upper end of the door 9.
The concave portion at the end of the pin 14 is adapted to engage with and disengage from the pin 14.

One end of a crank fitting 18 is connected to the lower end of the connecting rod 17 inside the door 9, and the other end of the crank fitting 18 has pins 19, 20 on the upper and lower surfaces.
is installed protrudingly. One end of a spring 20 is fixed to the downward pin 19, and the other end of the spring 20 is fixed to a protrusion 24 inside the door 9. A semicircular recess at one end of the push plate piece 22 faces the upward pin 21.

Approximately at the center of the inner surface of the door 9, as shown in FIG.
are fixed with a slight interval above and below, and a push plate 25 having a U-shaped cross section is fitted into the push plate mounting pieces 26, 26 so as to be able to move forward and backward. The push plate piece 22 is fixed to the inside of the push plate 25, and is urged outward together with the push plate 25 by springs 27, 27. Fourth
As shown in the figure, a support pin 28 is provided protruding from the hanging frame 8, and a locking hole 29 is provided protruding from the door 9 at a position opposite to the support pin 28. By engaging the support pin 28 and the locking hole 29 with each other, the opposite end B of the hanging frame 8 is suspended and supported.

A lower rail 30 is laid on the floor directly below the door 9, and the door hinge 12 is installed on the lower surface of the door 9.
A steady rest wheel 31 is provided substantially directly below the lower rail 30, and the steady rest wheel 31 is adapted to slide while being loosely fitted and guided by the lower rail 30. The upper surface of the end C remote from the door 9 of the fitted door 32 placed on the outdoor side is pivoted to the door 33 by a top hinge 34 serving as a pivot point, and the lower surface is attached to the floor by a floor hinge 36. It is pivoted.

Further, as shown in FIG. 2, a recess is formed on the upper surface of the end D of the closing door 32 near the door 9, and a latch pin 35 provided in the blind 33 is constantly press-fitted into this recess by a spring. ing. Then, when the closing door 32 is pushed from the indoor side to the outdoor side, the closing door 32 is pushed from the indoor side to the outdoor side.
2 is removed from the latch pin 35 and the top hinge 3
4 and the floor hinge 36 as fulcrums.

Next, the operation of the device according to the present invention will be explained.

When opening and closing the door 9 using the sliding method, the third
As shown in the figure, the door 9 and the hanging frame 8 are held in parallel by a crank ratchet 16. That is, the concave portion of the crank ratchet 16 is in contact with the pin 14, and as shown in FIG. It is in close contact with the hanging frame 8 while being suspended and supported via the door hinge 12 and the support pin 28. In this state, an automatic door slides to open and close by forward and reverse rotation of the motor, and a manual door slides to open and close manually.

In the case of an emergency such as a fire or an earthquake, or when a frontage larger than the door 9 is required for carrying in and out of machinery and equipment even during normal times, the push plate 25 of the door 9 is manually pushed. Then, the push plate 25 is pushed out against the springs 27, 27, and the tip of the push plate piece 22, which is integral with the push plate 25, pushes out the upward pin 21 toward the outdoors against the spring 20. Along with this, the crank fittings 18
rotates, and at the same time, the crank latch 16 turns toward the indoor side, and as the spring 20 moves outward from the connecting rod 17 as shown in FIGS. The engagement of 14 is released and the released state is maintained as it is.
Thereafter, the door 9 pivots toward the outdoors using the door hinge 12 and steady stop wheel 31 as fulcrums. When the door 9 turns, the door 9 and the closing door 32 partially overlap, so the closing door 3
2 is also pushed outward. Due to this turning pressure of the door 9, the latch pin 35 comes off against the spring, and the locking door 32 is moved to the top hinge 34 and the floor hinge 36.
Use this as a fulcrum to turn toward the outdoors. When the door 9 is swung with the door 9 closed or partially open, if the door 9 is manually slid while being swung, the door 9 moves to the rotational fulcrum position of the stopper door 32, and the door 9 is opened. A frontage twice as wide as 9 is obtained.

In addition, in the case of an automatic door, in order to prevent the door 9 from closing during or after turning, the control power is turned off or a limit switch is provided on the crank ratchet 16 or the like to stop the automatic door function.

After turning, to return the door 9 to its normal state, press the push plate 2.
5, the recess of the crank latch 16 and the pin 14 engage, and the crank latch 16,
The connecting rod 17 and crank fitting 18 return to their original states. Further, to return the closing door 32, the upper end of the closing door 32 is engaged with the latch pin 35 by manually pushing it from the outdoor side.

In the embodiment described above, the door 9 and the closing door 32 are arranged so that their main bodies partially overlap each other. but,
The method is not limited to this, but a rod-shaped object is fixed to a position that does not interfere with normal opening and closing, such as the upper end of the fitted door 32, and the rod-shaped object and the door 9 are overlapped with each other. The rod-like object may be pressed by swinging to swing the dead door 32.
In this case, when the length of the rod-like object is long, the pivot point of the door can be provided closer to the center.

In the embodiment described above, the door 9 and the hanging frame 8 are engaged with each other by the pin 14 and the crank latch 16, but they may be engaged with each other by a latch pin similar to the latch pin 35 of the closing door 32.

In the embodiment described above, a turning fulcrum was provided between the sliding door and the door, but it may also be provided between a fixed object such as a pillar other than the door.

In the above embodiments, the case where the door is opened on one side is explained, but it goes without saying that it may be opened on both sides.

Since the present invention is configured as described above, when the door is strongly pushed and turned, the inset door also turns at the same time.
You get twice as much frontage as the door. Therefore, it is no longer necessary to remove the door and the inlaid door from the open position, which is required in the past, and the labor required for removal and installation work is reduced.
You can save time. In addition, since the frontage twice as wide as the door can be quickly secured through a simple operation, especially in the event of an emergency such as a fire or an earthquake, the building can be evacuated more quickly and human disasters can be prevented. Furthermore, when the push plate of the door is pressed, the crank latch is removed from the pin of the hanging frame via the crank fitting and the connecting rod, so the hanging frame remains inside the opening and only the door turns. When the door is pushed back, it will automatically engage the hanging frame again. Furthermore, the engagement and disengagement mechanism between the crank ratchet and the pin in the engagement portion is simple and reliable.
