Description

The present invention relates to a technical field of a high-rise building, in particular, a door device including a door body with a ventilation mechanism provided at an entrance / exit part to the outside of an apartment house or the like.

In recent years, architectural styles based on high airtightness and high heat insulation have been widely used for buildings, and high airtightness and high heat insulation are common in buildings such as apartment buildings. In this way, when the building is made to be highly airtight and highly insulated, when the ventilation fan is used in the building (in each house), the inside of the building becomes negative pressure, and the entrance door is opened outward facing the outside In such a door device, the phenomenon that the opening operation becomes heavy occurs. In particular, in a house where a ventilator that operates for 24 hours is installed, if the ventilator is further operated due to cooking, etc., the pressure inside the house is further reduced, and the differential pressure inside and outside the door is increased. In addition to this, the opening operation becomes heavier and difficult to operate, but in addition to this, under the environment where the wind pressure acts on the door body, it is impossible for a powerless operator like a child to open the door body Is also envisaged.
Therefore, as a door device with a ventilation mechanism provided with a ventilation path (ventilation hole) that ventilates the inside and outside of the door body, and switching means that switches the ventilation path to either open or close state, When opening a door body, the thing which made it possible to eliminate the differential pressure inside and outside the house by opening the air passage is proposed.

In Patent Document 1, the air passage is formed by openings formed in the inner and outer surface plates of the door body, and is provided between the openings and is provided within the door thickness. The openings are communicated with each other by rotational displacement. The switching plate is configured as an opening / closing plate that transforms into a ventilation posture to be in a state and a blocking posture to block the communication state. The opening / closing plate is linked to the operation handle of the Gremon lock that is also used as the door body locking device, and the opening / closing plate rotates simultaneously with the unlocking of the door body in accordance with the rotation operation of the operation handle. The road is opened to ventilate the inside and outside of the door body. However, in this case, the operation handle is unlocked (rotation operation) to open the door body, and at the same time, air is vented through the air passage. For this reason, when the door body is pushed or operated by rotating the operation handle, or when the door body is opened by a series of operations for pulling, the air passage is pushed or pulled at the same time as it enters the ventilation state. Therefore, there is almost no time difference from the unlocking operation to pushing or pulling operation, and there is a case where ventilation (relative pressure difference) by the air passage is not sufficient, and in such a state, the door body is opened. Since the operation is heavy and a smooth opening operation cannot be performed, there is a problem that the opening must be performed with a time difference from the unlocking operation as appropriate, and the operability is poor. Further, in this case, not only is the opening formed in the outer side surface portion of the door body exposed to the outside, but there is also a problem that the opening and closing plate is exposed through the opening in the ventilation posture of the opening and closing plate and the design is inferior. is there.
In addition, in Patent Document 2, a notch portion in which a part of a door body is cut out is configured as a ventilation path, and a slide that slides within a door thickness to open and close the notch portion of the door body as a switching means. A plate is used, and the slide plate is held (locked) in the notch by a lock mechanism. When opening the door body, first release the locking mechanism that can also be used as the door body locking device, then manually slide the slide plate to open the notch, and then vent. The procedure of opening the door body by grasping the operation handle of the door body is a three-step operation of releasing the locking means, opening the slide plate, and opening the door body. . For this reason, it is possible to secure time to eliminate the pressure difference inside and outside before opening the door body, and the opening operation of the door body becomes light, but there is a problem that the operability is inferior because three steps of operation are required There is. Furthermore, this also has a problem that the design is impaired because the opening serving as the air passage is formed on the outer surface plate exposed to the outside of the door body.

In this case, the switching means 14 is inserted into the hollow portion within the door thickness through the through hole formed in the door end side end surface 5b of the door body 2 in a state in which members such as the partition body 16 are assembled in advance. The mounting plates 15n and 15p provided at the left and right end portions of the main body case 15 cover the through-holes opened in the door bottom side end surface and the door end side end surface 5b of the door body 2. By being fixed to the plate body 2b applied as much as possible, it is configured to be accommodated within the door thickness.
On the other hand, the second operating rod 11e that is long in the vertical direction is configured to be temporarily assembled using a guide body 11f provided in the door body 2 in advance, and the second locking device 11 and the switching means 14 are incorporated. At the stage, the upper end of the second operating rod 11e is connected to the first operating rod 11d, and the lower end of the second operating rod 11e is urged upward by the urging ammunition 18f. The first actuating rod 11d and the actuating plate 18 are configured to be coupled in an elastic manner by abutting against the abutting piece 18b. In the connecting step of the operating plate 18 and the second operating rod 11e, the operating plate 18 is urged toward the connecting portion with the second operating rod 11e by the urging ammunition 18f. Pushing downward against the biasing force of the ammunition 18f, the lower end of the second operating rod 11e is positioned above the contact piece 18b, and the biasing force of the biasing ammunition 18f is applied to the operating plate 18 from this state. By acting, the abutting piece 18b abuts on the second actuating rod 11e in a resilient manner, whereby the second actuating rod 11e and the abutting piece 18b are in an assembled state in which they can be detachably connected. Thus, the ventilation mechanism can be easily incorporated into the door body 2 by being assembled in this way.
Further, since the second operating rod 11e (second locking device 11 side member) and the operating plate 18 (switching means 14 side member) are in contact with each other, the locking device side member and switching means can be connected. The side member can be easily divided, and for example, it is configured so that maintenance of the exchange building of the switching means 14 can be easily performed. Further, when the partition 16 is inoperative in the closed position and the operating plate 18 is held at the position where it is moved downward, the second operating rod 11e moves upward while being separated from the contact piece 18b. Thus, the second locking device 11 can be unlocked, and there is no problem that the second locking device 11 remains locked when the switching means 14 is inoperative.
The contact piece 18b of the operating plate 18 and the second operating rod 11e can be integrally connected. In this case, the urging ammunition 18f can be dispensed with.

In the present embodiment configured as described, the ventilation mechanism of the door device 1 includes a lower opening 2a opened to ventilate the spaces (indoors and outdoors) facing the outer side surfaces 5a and 6a of the door body 2. The air passage is constituted by the inner opening 5a, and switching means 14 for holding the air passage in either an open state or a closed state. And the said switching means 14 is accommodated in the cavity part formed in the door thickness of the door body 2, and the 1st, 2nd locking device 10 provided with two or more in the door body 2 as an operation tool which switches the switching means 14, 11, the second locking device 11 is also used, and the ventilation path can be switched and held in either the open or closed state in conjunction with the operation of the second locking device 11. For this reason, the operation for bringing the second locking device 11 into the locked-unlocked posture as well as the operation for bringing the door body 2 into the ventilation state and the blocking state can be performed simultaneously by one action, and the operability is excellent.
Further, the switching means 14 can be operated only from the outside of the door body 2 by a person holding a key for locking and unlocking the second locking device 11, and the switching means 14 is switched by mischief. There is no such trouble, and it is excellent in crime prevention.
Further, by performing a normal operation for opening the door body 2, that is, an operation of unlocking the first and second locking devices 10 and 11, and then gripping the handle 9 of the door body 2. The differential pressure generated inside and outside the room due to the time difference between the unlocking operation and the opening of the door body 1 can be eliminated, and the door body 2 can be opened smoothly and lightly. As a result, when the door mechanism is opened at the same time as the ventilation mechanism is vented, as in the case where the ventilation mechanism is connected to the conventional operation handle, the pressure difference is not sufficiently eliminated and the door body is not opened. It is possible to surely prevent the problem of becoming heavy and to make the door body 2 smooth and light by performing the normal opening operation of the door body 2 regardless of whether or not a differential pressure is generated inside and outside the room. Can be opened.
Furthermore, the door body 2 unlocks the second locking device 11 in a state where the first locking device 10 is locked, so that the switching means 14 is in a vented state or a shut-off state when the door body 2 is locked. There is also an advantage that the inside and outside of the door body 2 can be ventilated without impairing crime prevention, and indoor ventilation can be performed in a high temperature season.

As described above, in the embodiment in which the present invention is implemented, the switching means 14 of the ventilation mechanism opens and closes the partition body 16 that opens and closes the ventilation path, and opens the ventilation path. The first and second actuating rods 11d are configured to be provided with an actuating plate 18 that switches to any one of the closed attitudes, and is displaced in the up-down direction in accordance with the locking-unlocking operation of the second locking device 11. , 11e are connected to each other, and the operating plate 18 is biased toward the connecting portion with the second operating rod 11e by the biasing ammunition 18f, whereby the second operating rod 11e and the operating plate 18 are connected. It is in a detachable connection state where the connection is simply abutting. As a result, it is not necessary to directly integrate the second actuating rod 11e, which is the first actuating rod 11d side member, with the actuating plate 18, and the second locking device 11 with the first actuating rod 11d and the switching means 14 on the door body 2. Can be easily interlocked and connected within the door thickness, and not only the assembling work is facilitated but also the switching means 14 needs to be replaced, for example. There is also an advantage that the replacement work can be easily performed.
In addition, when the partition 16 is inoperative in the closed position and the operation plate 18 is held at the lowered position, the second operation rod 11e is moved upward while being separated from the contact piece 18b. Thus, the second locking device 11 can be unlocked, and it is possible to reliably prevent such a problem that the second locking device 11 remains locked due to the inoperative operation of the switching means 14.

  The pressure difference between the inside and outside of the door body 2 can be eliminated with good operability, and the door body 2 can be opened easily. In this case, the air passage constituting the ventilation mechanism constitutes the lower end surface of the door body 2. Among these, the lower opening 2a established in the outer bent pieces 5c and 6c and the inner opening 5d established in the lower end of the inner side surface portion 5a are air passage opening / closing members constituting the switching means 14. Since the partition 16 is provided between the door lower opening 2a and the inner opening 5a, no opening is formed in the outer surface portion 6a exposed to the outside of the door body 2, and the design is excellent. The door body 2 can be obtained.

  Further, in this case, the lower end surface of the door body 2 is formed with a stepped portion at the intermediate portion in the inner and outer direction, and the facing distance between the outer bent piece 6c serving as the outer portion of the stepped portion and the lower frame body 3c serving as the floor side surface. However, since the distance between the inner bent piece 5c and the lower frame 3c is larger than the facing distance, air from the outside of the door body 2 can be easily taken into the inside, and the differential pressure is eliminated by further increasing the ventilation by the ventilation mechanism. Can be further shortened.

Of course, the present invention is not limited to the above-described embodiment, and may be the second embodiment shown in FIG.
In the second embodiment, the door body 20 with a ventilation mechanism is constituted by a pair of inner and outer surfaces, outer surface plates 21 and 22, and a ventilation path is constituted by a lower opening (not shown) and an inner opening 21a. A partition (not shown) for the switching means 23 is provided between the lower opening and the inner opening 21a. And, the basic configuration is that the first locking device 23 is the second locking device 25 side of the first and second locking devices 24, 25 provided on the door body 20. The configuration is the same as that of the embodiment, and it is configured to obtain the same effect as that of the first embodiment. And in this thing, the some through-hole 21c is opened in the food | hood body 21b which blocks | closes with the predetermined clearance gap H around the inner side opening 21a. Thereby, in the ventilation mechanism of the second embodiment, the air flow rate on the inner opening 21a side can be increased, the ventilation inside and outside the door body 20 is further promoted, and the differential pressure elimination time can be further shortened. .

Furthermore, the third embodiment shown in FIG. 9 can be used.
In the third embodiment, the first actuating rod 26a provided in the second locking device 26 is provided so as to move up with the locking operation of the second locking device 26 and to move down with the unlocking operation. The second operating rod 26b connected to the first operating rod 26a is linked to the operating plate 27a of the switching means 27. Then, in the locked state of the second locking device 26, as shown in FIG. 9A, the operating plate 27a biased upward by the biasing force of the biasing ammunition 27b closes the partition body 27c. In the unlocked state of the second locking device 26, as shown in FIG. 9B, the actuating plate 27a opens the partitioning body 27c against the biasing force of the biasing ammunition 27b as shown in FIG. It is configured. In this case, since the partition body 27c is in the closed position in a state where it receives the urging force of the urging ammunition 27b, the partition body 27c abuts on a stopper piece (not shown) in a resilient manner. There is an advantage of being blocked.

Moreover, it can also be made like 4th Embodiment shown in FIG.
In the fourth embodiment, the basic configuration is the same as that of the first embodiment, and the same member configuration is denoted by the same reference numeral as that of the first embodiment, and the description thereof is omitted. In this case, an emergency urging ammunition 29 is interposed in the second operating rod 28b connected to the first operating rod 28a extending from the second locking device 28 at an intermediate portion. The emergency urging ammunition 29 is set to an urging force larger than the urging force of the urging ammunition 18f for urging the operating plate 18 of the switching means 14. In a normal use state, when the first and second actuating rods 28a and 28b are moved down along with the locking operation of the second locking device 28, the emergency urging ammunition 29 does not interfere and is attached. The operating plate 18 is moved downward against the urging force of the ammunition machine 18f to bring the partition 16 into the closed position, and the first and second operating rods 28a and 28b are raised as the second locking device 28 is unlocked. In the case of movement, the partition plate 16 is configured to be in the open posture by receiving the biasing force of the biasing ammunition 18f and moving the operating plate 18 upward.
On the other hand, in the case where an unexpected situation occurs and the partition 16 of the switching means 14 becomes inoperative in the ventilation posture, and the operating plate 18 is held in the upwardly moved position, the second locking is performed. With the locking operation of the device 28, the upper part of the emergency urging ammunition 29 of the first operation rod 28 a and the second operation rod 28 b is moved down against the urging force of the emergency urging ammunition 29. Thus, the second locking device 28 is configured to be in a locked state.
Further, when the partition 16 is inoperative in the closed position and the operation plate 18 is held at the lowered position, the second operation rod 28b is separated from the contact piece 18b of the operation plate 18 as described above. The second locking device 28 is configured to be unlocked by moving up in a separated state. Thus, by providing the emergency urging ammunition 29, the locking / unlocking function of the second locking device 28 is not impaired even if any unexpected situation occurs in the switching means 14. it can.
Incidentally, the emergency urging ammunition is in the middle part of the operating rod and may be inserted in any part up to the operating plate. When the displacement of the direction is restricted, any configuration can be used as long as the operation of the locking device is not impaired by allowing the vertical displacement of the portion of the operating rod on the locking device side.
