Description

[Detailed description of the invention] [Industrial application field] This invention normally opens and closes the movable door by sliding to open the frontage as much as necessary, and in emergencies, the movable door and fixed door can be opened and closed by swinging. This invention relates to a door opening/closing device that can be opened and closed to widen the frontage.

[Prior art and its problems] As a door opening/closing device, a device in which a movable door is slid laterally to open and close the frontage is widely used. Since it cannot be opened, it may not be possible to widen the frontage. However, it is necessary to open the frontage widely when loading and unloading large items or in case of evacuation due to fire or the like. For this reason, conventionally, movable doors are usually opened and closed by sliding to open the frontage as necessary, and in emergencies, movable and fixed doors can be opened and closed by swinging to open the frontage wider. However, in the past, this type of device was extremely dangerous because the door would swing even when opened and closed by a normal slide.

[Purpose of the invention] This invention was made to improve the above-mentioned situation, and its purpose is to ensure that the lock is activated to prevent the door from swinging when the movable door is opened and closed by sliding normally. It is safe to use, and when the movable door is moved beyond its normal opening, the lock automatically releases and the door can be opened and closed by swinging, opening up a wide opening.
Another object of the present invention is to provide a door opening/closing device that can more reliably operate the lock of a movable door.

[Main points of the invention] In order to achieve the above-mentioned purpose, this invention includes a traveling body that slides laterally along a rail, a movable door whose outer end is pivotally supported to the traveling body via a pin, A fixed door is provided at a widthwise offset from the movable door and whose upper and lower outer ends are pivoted to the frame and the floor via pins, and the fixed door and frame are removably locked. a first locking body that is attached to the traveling body so as to be movable up and down, and a second lock that detachably locks with the movable door when the movable door is moved within the normal opening degree. and first and second pressing members that release the locks of the first and second locking bodies when the movable door moves beyond the normal opening degree, and when the movable door moves beyond the normal opening degree. When the lock is released, both doors can be opened and closed by swinging.

[Example] Hereinafter, an example in which this invention is applied to a quadruple door will be described with reference to an example shown in the drawings. In the figure, reference numeral 1 denotes two movable doors that can be slid laterally, and these doors 1 are designed to move in the direction of arrow A to open and to move in the opposite direction to close. Two fixed doors 2 are provided on both sides of the movable door 1, shifted in the width direction, and the upper and lower ends of the outer sides of the fixed doors 2 are connected to a frame 5 and a frame 5 by pins 3 and 4, respectively. Each of the fixed doors 2 is pivotally supported on the floor 6, and a lock, which will be described later, is provided at the upper end of each inner side of both fixed doors 2. A rail 7 is fixed to the frame 5 via a support member 5a, and a roller 9 pivotally supported on the upper part of the traveling body 8 is rolled onto the rail 7. Further, the outer upper end of the movable door 1 is pivotally supported on the traveling body 8 by a pin 10, and
A pin 11 is provided coaxially with the pin 10 at the outer lower end of the movable door 1, and this pin 11 is inserted into a groove 12 formed in the floor portion 6 along the moving direction of the movable door 1. A lock, which will be described later, is provided at the inner upper end of the movable door 1. Furthermore, when a passerby or the like is located near the movable door 1, this is detected and an electric motor (not shown) is activated, causing the movable door 1 to travel on the rail 7 via the traveling body 8. It opens automatically, and when a passerby leaves, the electric motor operates in the opposite direction and closes it automatically.
The movable door 1 is configured to be moved by changing its opening degree into two stages by operating a switch. That is, when the switch (not shown) is set to S _W1 , the movable door 1 can be opened and closed by sliding within the normal opening range (X in Figure 2). When the switch is switched to the S _W2 position, the movable door 1 slides to a position above the normal opening degree (Y in FIG. 2). Furthermore, when the movable door 1 is normally located at the opening degree X, if you change the switch to S _W2 , the movable door 1 will automatically slide from the X position to the Y position. There is. Further, when the power is cut off due to a power outage or the like, the movable door 1 can be manually moved to the Y position.

Next, the lock on the fixed door side will be explained. Mounting plate 13 fixed to the lower end of the frame 5
A support plate 14 is fixed to the support plate 14, the upper part of the swinging member 15 is pivotally supported on the support plate 14 via a shaft 16, and a first locking body 17 is provided protruding from the lower side of the tip of the swinging member 15. At the same time, an upward inclined surface 18 is formed on the upper side of the other end of the swinging member 15, and a compression spring 20 is interposed between the back surface of this inclined surface 18 and a receiving plate 19 fixed to the mounting plate 13, Since the tip of the swinging member 15 is always biased downward due to the elastic force of the spring 20, the first locking body 17 is normally attached to the frame 5.
Through this hole, the fixed door 2 is removably engaged with a locking hole 22 formed in a locking member 21 fixed to the upper part of the fixed door 2, thereby locking the fixed door 2. Furthermore, a first pressing member 23 is attached to the traveling body 8.
is fixed, and an inclined surface 24 is formed at the tip of the first pressing member 23, and when the movable door 1 moves beyond the normal opening degree (Y in FIG. 2), the inclined surface 24 of the pressing member 23 swings. When the member 15 is pressed while sliding on the inclined surface 18, the swinging member 15 swings about the shaft 16 against the elastic force of the compression spring 20, and the first engagement at the tip of the swinging member 15 is caused. The stopper 17 lifts up and comes out of the locking hole 22 on the fixed door 2 side,
The lock is now being released. Next, to explain the locking mechanism on the movable door 1 side, a mounting body 26 is fixed to a fixed plate 25 fixed to the traveling body 8, and a second locking body 27 is attached to this mounting body 26 so as to be movable up and down. At the same time as installing this second locking body 2
A compression spring 29 is interposed between the upper surface of the second locking body 27 and the receiving plate 28 fixed to the mounting plate 26, and the elastic force of the compression spring 29 causes the locking portion 30 at the lower end of the second locking body 27 to move. A locking portion 30 protruding downward from the mounting body 26 is located below the outside of a locking member 31 fixed to the upper end of the movable door 1. It is designed to act as a stopper to lock the movable door 1 and prevent the door 1 from swinging. Furthermore, the locking body 2
A rotating body 32a is attached to the protruding tip of a shaft 32 that protrudes along the horizontal direction on the outside of 7, and
The second pressing member 33 is fixed to the frame 5, and when the movable door 1 moves beyond the normal opening degree (Y in FIG. 2),
The inclined surface 34 of the second pressing member 33 slides on the rotating body 32a and pushes up the second pressing member 33.
The locking body 27 moves upward against the elastic force of the compression spring 29, and the locking part 30 formed at the bottom of the second locking body 27 lifts up above the locking member 31 and moves. Door 1 is now unlocked. In the figure, reference numeral 35 denotes a support plate fixed to the fixed plate 25. This support plate 35 is inserted below the locking member 31 and slidably receives it, so that the inside of the movable door 1 under normal conditions is It is designed to accept the following. In addition, 36 in the figure is the fixed door 2.
A ball 36 is provided on the side and pressed by a spring, and this ball 36 elastically engages with the engagement hole 37 on the frame 5 side to position the fixed door 2 during normal operation. .

To explain the operation of the door opening/closing mechanism configured as described above, when a passerby approaches the moving door 1, this is sensed and the electric motor is activated, and the moving door 1 is automatically moved to the direction indicated by the arrow 1. The movable door 1 is moved in the direction to open the frontage, and when there are no passersby, the electric motor is reversed and the movable door 1 is automatically closed. and,
Normally, when a switch (not shown) is set to _SW1 , the movable door 1 moves within the normal opening range (X in Figure 2) to open only the required opening. Therefore, the movable door 1 only moves by the normal opening degree (X in FIG. 2) under normal conditions, so the locking body 17
is locked by being locked in a locking hole 22 formed in a locking member 21 fixed to the fixed door 2, and a second locking body 27 attached to the traveling body 8 side
A locking member 3 having a locking portion 30 fixed to the movable door 1
Since both doors 1 and 2 are locked in this way, they can be used safely without swinging. Also, taking in and out large luggage,
If it is necessary to widen the frontage for evacuation due to fire, etc., turn on a switch (not shown).
S Switch to _W2 position. Then, as shown in Fig. 9, when the movable door 1 is fully closed, 0→Y
When it is at the normal opening degree (X in Figure 2), it moves from X to Y, that is, the movable door 1 slides to the position above the normal opening degree (Y in Figure 2). automatically move. Then, the inclined surface 24 of the first pressing member 23 fixed to the traveling body 8 presses while sliding on the inclined surface 18 of the swinging member 15, so that the swinging member 15 swings about the shaft 16 and swings. The first locking body 17 at the tip of the moving member 15 lifts up and comes out of the locking hole 22 on the fixed door 2 side.
The fixed door 2 is unlocked. At the same time, when the movable door 1 is moved beyond the normal opening degree, the inclined surface 34 of the second pressing member 33 fixed to the frame body 5
2a, the second locking body 27 attached to the traveling body 8 moves upward, and the locking part 30 formed at the lower part of the second locking body 27 moves above the locking member 31. Lift it up to the point where it unlocks moving door 1. Then, when both the doors 1 and 2 are overlapped in the width direction and the inside is pressed, the fixed door 2 uses the pins 3 and 4 as fulcrums, and the movable door 1 uses the pins 10 and 11 as fulcrums.
They are each swung open in the direction of arrow B using the fulcrum as a fulcrum, and therefore the frontage can be opened widely. In addition, if the movable door 1 moves beyond the normal opening degree,
It can be used safely if the power turns off automatically.

In addition, if the power is cut off due to a power outage or the like while the movable door 1 is closed or at the normal opening, the movable door 1 can be moved manually. Y in Figure 2)
When moved to the position , the lock is released and both doors 1 and 2 can be swung open in the direction of arrow B, allowing a wide opening even during a power outage. Also, doors 1 and 2 that swing open
When the movable door 1 is returned to its original position and moved inward to a position within the normal opening degree, both doors 1 and 2 are locked and cannot be swung, allowing them to be used in a normal state.

In addition, although the above-mentioned example explained the quadruple door, it goes without saying that it is applicable also to the double door which provided one movable door and one fixed door.

[Effects of the invention] As detailed above, this invention includes a traveling body that slides laterally along the rail, a movable door whose outer end is pivotally supported to the traveling body via a pin,
A fixed door is provided at a widthwise offset from the movable door and whose upper and lower outer ends are pivoted to the frame and the floor via pins, and the fixed door and frame are removably locked. a first locking body that is attached to the traveling body so as to be movable up and down, and a second lock that detachably locks with the movable door when the movable door is moved within the normal opening degree. and first and second pressing members that release the locks of the first and second locking bodies when the movable door moves beyond the normal opening degree, and the movable door moves beyond the normal opening degree. When this occurs, the lock is released, and both doors can be opened and closed by swinging using the pins as fulcrums while the doors are weighted down in the width direction. Therefore, when the movable door is moved by sliding to open only the required opening, the lock is reliably activated during normal opening and closing, and the door cannot swing, making it safe to use and preventing large items from being taken in and taken out or fires. In the event of an evacuation, if the movable door is moved beyond the normal opening degree, the movable door and fixed door will be automatically unlocked, and both doors can be opened and closed by swinging with them overlapped in the width direction, allowing for wide openings and closings. It can be used very reliably and efficiently. Furthermore, when the movable door is locked by the lower end of the locking body that is vertically movably attached to the traveling body that slides laterally with the movable door, and when the locking body is moved,
Since the lock is released, the locking mechanism of the movable door can be operated reliably.
