Description

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

[Prior art and its problems] A door opening/closing device that opens and closes the frontage by sliding the door laterally is widely used, but in this type of door, the part corresponding to the door pocket is 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, door opening/closing devices have traditionally been used that normally open and close the door by sliding it to open the frontage as much as necessary, and in emergencies, open and close the door by swinging to open the door wider. has been done.

In addition, since this type of moving door is generally made to be strong, it is quite heavy, and in order to slide or swing such a heavy moving door, it must be supported firmly and firmly. If the level of the movable door is off, it will not swing smoothly, so it is necessary to adjust the level of the movable door reliably. For this reason, some models have conventionally installed movable doors with adjusting screws, tightening bolts, etc., but conventional models were only attached to one side of the support shaft, so they could tilt during use. In some cases, it was not possible to reliably maintain levelness.

[Purpose of the invention] This invention was made to improve the above-mentioned situation, and its purpose is to be able to support the movable door reliably and firmly, and to adjust the levelness of the movable door reliably. Therefore, it is an object of the present invention to provide a door opening/closing device that allows a movable door to swing smoothly.

[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 that is offset in the width direction 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 the 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. a first and second pressing member that unlocks the first and second locking bodies when the movable door moves beyond a normal opening degree, and a support plate fixed to the traveling body; A mounting plate is arranged vertically and rotatably supported by two thrust bearings provided on the upper and lower sides of this support plate, and an adjustment screw and a tightening screw are attached to this mounting plate on one side of the support shaft. The movable door is attached to the other side of the support shaft via the tightening bolt and spacer.

[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 two movable doors 1, shifted in the width direction, and the upper and lower ends of the outside of each of these two fixed doors 2 are connected to a frame 5 by means of pins 3 and 4. Each of the fixed doors 2 is pivotally supported on the floor 6, and a lock portion, 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. Then, as described later, the movable door 1
The outer upper end of the traveling body 8 is connected to the traveling body 8 via the support shaft 10.
A pin 11 coaxial with the pin 10 is provided protruding from the outer lower end of the movable door 1, and a rotating body 11a pivotally supported on the outer periphery of the pin 11 is attached to the floor 6. It is inserted into a groove 12 formed along the moving direction of the movable door 1, and a lock portion, 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, but this movable door 1 can be moved by switching the opening degree to two stages by operating a switch. I'm starting to do that. 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). In addition, moving door 1
When the switch is set to S _W2 when the door is at the normal opening (X), the movable door 1 moves from the X position to the Y position.
It automatically slides into position. 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 portion on the fixed door side will be explained. Mounting plate 13 fixed to the lower side 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 locking body 17 is normally fixed to the upper part of the fixed door 2 through the hole in the frame 5. Locking member 2
The fixed door 2 is lockable by being removably engaged with a locking hole 22 formed in the fixed door 2. Further, a first pressing member 23 is fixed to the traveling body 8, and an inclined surface 24 is formed at the tip of the first pressing member 23.
is formed, and when the moving door 1 moves beyond the normal opening degree (Y in FIG. 2), the inclined surface 24 of the first pressing member 23 presses while sliding with the inclined surface 18 of the swinging member 15. , the swinging member 15 is the compression spring 2
swings about the shaft 16 as a fulcrum against an elastic force of 0,
The first locking body 17 at the tip of the swinging member 15 lifts up and comes out of the locking hole 22 on the fixed door 2 side, releasing the lock portion. Next, the lock part on the movable door 1 side will be explained. A mounting body 26 is fixed to a fixed plate 25 fixed to the traveling body 8, and a locking part 27 is mounted to this mounting body 26 so as to be movable up and down. A compression spring 2 is inserted between the upper surface of this locking portion 27 and a receiving plate 28 fixed to the mounting plate 26.
9 is interposed, and the elastic force of this compression spring 29 causes the second locking body 30 at the lower end of the locking part 27 to move to the mounting body 2.
A second locking body 30 protrudes below the movable door 1 and is located below the outside of the locking member 31 fixed to the upper end of the movable door 1. The locking member 31 acts as a stopper to lock the movable door 1 and prevent the door 1 from swinging. Furthermore, the locking portion 27
A rotating body 32a is attached to the protruding tip of a shaft 32 that protrudes along the horizontal direction on the outside of the frame 5, and a second pressing member 33 is fixed to the frame 5, so that the movable door 1 is opened more than the normal opening degree ( When the second pressing member 33 moves (Y) in FIG. 2, the inclined surface 34 of the second pressing member 33 slides with the rotating body 32a and pushes up, and the locking part 27 moves upward against the elastic force of the compression spring 29. The second locking body 30 formed at the lower part of the locking portion 27 is lifted up above the locking member 31 to unlock the movable door 1.

Next, the supporting portion of the movable door 1 described above will be described in detail with reference to FIGS. 3, 9, and 10. That is,
A support plate 35 made of angle material is fixed to the lower side of the fixed door 2 side of the traveling body 8, and a reinforcing plate 36 is fixed to the lower side of this support plate 35. A through hole 37 is formed through the plate, and both plates 35 and 3 are coaxially connected to the hole 37.
Both thrust bearings 38 and 39 are installed above and below 6, respectively. Furthermore, the shaft portion 10a of the support shaft 10 described above is supported in the mounting holes of both the thrust bearings 38 and 39, and the head portion 10a of the support shaft 10 is
The lower surface of 0b is brought into contact with the upper surface of the upper thrust bearing 38 via the seat plate 40. Further, the lower part 10c of the support shaft 10 is made to protrude, and the support shaft 1
The side portion of the mounting plate 41 is fixed to the protruding lower part 10c of the mounting plate 41, and a seat plate 42 is interposed between the upper surface of the mounting plate 41 and the lower surface of the lower thrust bearing 39. Then, the movable door 1 is attached to the lower side of the mounting plate 41. That is, after adjusting the lower protrusion length of the adjusting screw 43 screwed into the mounting plate 41, the lower protrusion of the tightening bolt 44 attached to the mounting plate 41 is inserted into the upper frame of the movable door 1. 1a and tighten, and the movable door 1 is attached to the mounting plate 41 via the bolt 44, so that the movable door 1 swings about the support shaft 10 as a fulcrum. In addition, since the protruding lower end surface of the adjustment screw 43 is in contact with the upper surface of the upper frame 1a of the movable door 1, this screw 4
The horizontality of the movable door 1 is adjusted by adjusting the protruding length of the movable door 3 and by interposing a spacer 45 between the mounting plate 41 and the upper frame 1a. In the figure, reference numeral 46 denotes a support plate fixed to the fixed plate 25, and this support plate 46 is inserted below the locking member 31 and slidably receives it, so that the inside of the movable door 1 in normal conditions. It is designed to accept the following. In addition, 47 in the figure is the fixed door 2.
A ball 47 is provided on the side and pressed by a spring, and this ball 47 elastically engages with the engagement hole 48 on the frame 5 side, thereby positioning the fixed door 2 during normal operation. .

To explain the operation of the door opening/closing device configured as described above, when a passerby approaches the movable door 1, this is sensed and the electric motor is activated, and the movable 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, since the movable door 1 normally only moves by the normal opening degree (X in FIG. The second locking body 30 of the locking part 27 attached to the traveling body 8 is locked by being locked in the locking hole 22, and the second locking body 30 of the locking part 27 attached to the traveling body 8 side is located below the outside of the locking member 31 fixed to the movable door 1. In this way, both doors 1 and 2 are locked by the locking portion, so both doors 1 and 2 can be used safely without swinging. When it is necessary to widen the frontage for loading and unloading large items or for evacuation due to fire, etc., a switch (not shown) is moved to the _SW2 position. Then, as shown in Fig. 11, when the movable door 1 is fully closed, it moves from 0 to Y, and when it is at the normal opening (X in Fig. 2), it moves from X to Y. In other words, the movable door 1 automatically slides to a position above the normal opening degree (Y in FIG. 2). Then, the first pressing member 23 fixed to the traveling body 8
Since the inclined surface 24 of the swinging member 15 slides and presses against the inclined surface 18 of the swinging member 15, the swinging member 15 swings about the shaft 16 as a fulcrum, and the first locking body 17 at the tip of the swinging member 15 is held. Since it goes up and exits from the locking hole 22 on the side of the fixed door 2, the lock of the fixed door 2 is released. 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 pushes up the rotating body 32a, so that the locking part 27 attached to the traveling body 8 moves upward,
The second locking body 30 formed at the lower part of the locking portion 27 is lifted up to above the locking member 31, and the movable door 1
to release the lock. Then, when the above-mentioned doors 1 and 2 are stacked in the width direction and the inside is pressed,
The fixed door 2 uses pins 3 and 4 as fulcrums, and the movable door 1 uses pins 10 and 11 as fulcrums to swing and open in the direction of arrow B, so that the frontage can be opened widely. In addition, if the movable door 1 is moved beyond the normal opening degree, the power is automatically turned off.
Safe to use.

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 part is released and both doors 1 and 2 can be swung open in the direction of arrow B, thereby making it possible to widen the frontage even in the event of 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 this invention, the movable door 1 is supported by the support shaft 10 attached to the upper and lower sides of the support plate 35 fixed to the traveling body 8, etc., and attached to both thrust bearings 38 and 39. The movable door 1 can be supported reliably and firmly, and
Attach the moving door 1 to a mounting plate 41 fixed to the lower part of the support shaft 10. Attach the adjustment screw 43, tightening bolt 44, and spacer 45 on one side of the support shaft 10, and attach the tightening bolt 44 and spacer 45 on the other side of the support shaft 10. 45, the horizontality of the movable door 1 can be reliably adjusted and maintained, and the movable door 1 can be smoothly swung.

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 that is offset in the width direction 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 the 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. a first and second pressing member that unlocks the first and second locking bodies when the movable door moves beyond a normal opening degree, and a support plate fixed to the traveling body; a mounting plate arranged vertically and rotatably supported by two thrust bearings provided on the upper and lower sides of the support plate;
An adjusting screw, a tightening bottle, and a spacer are attached to this mounting plate on one side of the support shaft, and the movable door is attached to the other side of the support shaft via the tightening bottle and spacer. Therefore, during normal opening and closing, when the moving door is moved by sliding and only the necessary opening is opened, the lock part is reliably activated and the door cannot swing, making it safe to use and making it easier to put in and take out large items. In the event of an evacuation due to a fire, if the movable door is moved beyond its normal opening degree by switching the switch, the locks on the movable door and fixed door will be automatically released, allowing both doors to be opened and closed by swinging with the doors overlapped in the width direction. Therefore, the frontage can be opened and closed widely, and it can be used very reliably and efficiently. Furthermore, a mounting plate is attached to the lower part of the support shaft supported by two thrust bearings provided on the upper and lower sides of the support plate fixed to the traveling body, and one side of the support shaft is attached to this mounting plate with an adjustment screw. , tighten the bottle and spacer,
