JP5029903B2 - Fixture vibration suppression structure when opening and closing the hinged door - Google Patents

Description

  The present invention is a closed space provided with a hinged door that is isolated from the outside by a partition wall and can be opened and closed in the front-rear direction, and a fitting that is guided by a rail and is slidable in the left-right direction. The present invention relates to a structure vibration suppression structure at the time of opening and closing a hinged door that suppresses the occurrence of vibrations in the furniture due to fluctuations.

  In buildings such as houses, when entering the entrance hall inside the building from the outside of the building, or when going out of the building from the entrance hall, the air pressure in the entrance hall fluctuates rapidly as the front door opens and closes. Therefore, there is a problem that the joinery provided in the entrance hall that can be opened and closed vibrates, and a rattling sound is generated or an impact is applied to the joinery. In addition, the airtightness of houses has been increasing in recent years from the viewpoint of cooling and heating efficiency, etc. In addition to the fact that the airtightness of the entrance hall has increased in recent years, the fixtures provided at the boundary of the entrance hall are walls so that the cold air of the entrance hall does not flow into the adjacent room In many cases, the airtightness of the entrance hall is further increased. Therefore, sudden pressure fluctuations are likely to occur in the entrance hall when the entrance door is opened and closed, and the problem of the vibration of the joinery becomes more prominent.

  In particular, in the case of so-called sliding doors where the joinery slides in the left-right direction and opens and closes, there is no gap between the floor and the so-called swing door that rotates in the front-rear direction, so the entrance hall is more airtight. High pressure is likely to occur when opening and closing the front door. Furthermore, such a sliding door has a structure in which a doorwheel provided rotatably at the lower end of the sliding door is fitted to a rail laid on the floor so that the doorwheel can smoothly rotate. Since some play is provided, this play is likely to be loose.

  As a means for suppressing such a problem, a method for attaching a rattle-preventing member to a fitting has been proposed. FIG. 12 is a schematic perspective view showing a configuration of a rattling prevention device 70 according to a conventional example (see Patent Document 1). The rattling prevention tool 70 includes a mounting portion 71 having an L-shaped vertical cross section and a pair of flexible pieces 72 that are curved and extended from the mounting portion 71. When the mounting portion 71 is attached to the upper edge of the sliding door and the flexible piece 72 bulges to the side of the sliding door and the upper end portion of the sliding door is fitted into the duck groove, The flexible piece 72 comes into contact with the side surface of the Kamoi groove. With such a configuration, the vibration generated in the sliding door is absorbed by the bending deformation of the flexible piece 72, and the sliding door does not come into direct contact with the duck groove and no rattling noise is generated, and no impact is applied to the sliding door.

  Moreover, the method of attaching what is called a door closer to the entrance door as another means to suppress the said problem is proposed conventionally (refer patent document 2). This door closer is a device for reducing the impact and sound at the moment when the door is closed by reducing the door closing speed using hydraulic pressure or the like. If this door closer is attached to the entrance door, the entrance door closes at a slow speed, so that the air pressure in the entrance hall does not fluctuate rapidly. Therefore, it is possible to prevent the joinery from vibrating when the entrance door is closed.

  However, in the structure in which the rattle prevention tool 70 is attached to the joinery, it is necessary to prepare the rattle prevention tools 70 as many as the number of the joinery and perform the attachment work respectively. This causes a problem that the cost increases and the attachment work becomes complicated.

  In addition, in the structure where the door closer is attached to the entrance door, the primary role played by the door closer is to mitigate the impact and sound at the moment when the door closes. There is a problem that the effect cannot be sufficiently obtained. On the other hand, if the door closer is set so that the closing speed of the entrance door is extremely low so that fluctuations in the air pressure in the entrance hall can be sufficiently suppressed, the time until the entrance door closes becomes very long and the usability becomes poor. There's a problem. Moreover, according to the door closer, although the fluctuation | variation of the atmospheric pressure of the entrance hall that occurs at the moment when the entrance door closes can be suppressed, there is also a problem that the fluctuation of the atmospheric pressure of the entrance hall that occurs at the moment when the entrance door opens cannot be suppressed. Furthermore, since the door closer is generally hydraulic and the impact mitigation effect depends on temperature, there is a problem that the door closer must be adjusted every season in order to keep the door closing speed constant.

  The present invention has been made in view of such a problem, and a means capable of sufficiently suppressing, with a simple configuration, sudden pressure fluctuations in the entrance hall that occur when the entrance door closes and opens. provide.

  In order to achieve the above object, the vibration control structure for opening and closing the hinged door according to the present invention is separated from the outside by a partition wall, and can be opened and closed in the front-rear direction.

  Further, in the fitting vibration suppression structure when opening and closing the hinged door according to the present invention, the ventilation mechanism includes a gap formed between the hinged door and the partition wall, and a gap adjusting member that blocks or opens the gap. Is.

  In addition, in the fitting vibration suppression structure when opening and closing the hinged door according to the present invention, the ventilation mechanism includes a ventilation window penetratingly formed in the hinged door, and a window adjusting member that blocks or opens the ventilation window. .

  According to the fixture vibration suppression structure at the time of opening and closing the hinged door according to the present invention, when the hinged door is in a closed state or in an opened state and the atmospheric pressure inside and outside the closed space is equal, the atmospheric pressure fluctuation suppression valve is connected to the ventilation duct. The internal cavity is closed, and the airtightness and soundproofing of the adjacent room to which the other end of the ventilation duct is connected are ensured. On the other hand, when the opening / closing operation of the hinged door is started and an instantaneous pressure difference occurs between the inside and outside of the enclosed space, the atmospheric pressure fluctuation control valve opens the inside cavity of the ventilation duct, so that the inside and outside of the enclosed space are The atmospheric pressure is equal. Accordingly, it is possible to suppress a sudden change in atmospheric pressure in the closed space when the hinged door is opened and closed, and it is possible to prevent the fitting from vibrating and causing a rattling sound or an impact.

  Further, according to the structure for suppressing vibration of a door when opening and closing the hinged door according to the present invention, the vibration of the door that is generated when opening and closing the door is sufficiently suppressed with a simple configuration and without being affected by surrounding environmental conditions. can do.

  First, a joinery vibration suppressing structure when opening and closing a hinged door according to a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic longitudinal sectional view showing a joinery vibration suppressing structure 1 (hereinafter simply referred to as a “jointing tool vibration suppressing structure”) when opening and closing the hinged door according to the first embodiment. The joinery vibration suppression structure 1 includes a ventilation duct 5 that communicates between the entrance hall 3 of the house 2 and the adjacent room 4, and an atmospheric pressure fluctuation that is provided inside the ventilation duct 5 and suppresses an atmospheric pressure fluctuation inside the entrance hall 3. And a suppression valve 6.

  FIG. 2 is a schematic perspective view of the entrance hall 3 according to the present embodiment as viewed from the indoor side. The entrance hall 3 is a closed space that is isolated from the outdoor 10 by being surrounded by a floor 7, a ceiling 8, or a wall 9 as a partition wall, and a hinged door 11 is provided on the wall 9 facing the outdoor 10 so that it can be opened and closed. On the other hand, a sliding door (joint) 12 is provided on the wall 9 facing the adjacent room 4 shown in FIG. Although not shown in FIG. 2, a wall 9 as a partition wall is also provided on the front side of the sheet.

  The hinged door 11 is an entrance door for going back and forth between the entrance hall 3 and the outdoor 10. Here, FIG. 3 is a schematic front view of the hinged door 11 as seen from the entrance hall 3 side. The hinged door 11 is configured by attaching handles 15 for opening and closing to both the front and back surfaces of a door plate 14 provided with a daylighting window 13. The hinged door 11 configured as described above is arranged so as to close the opening 16 formed in the wall 9 facing the outdoor 10, and the end opposite to the handle 15 is fixed to the wall 9 via a hinge 17. In addition, a conventionally known door closer 18 capable of adjusting the closing speed is attached to the upper portion thereof. As a result, the hinged door 11 can be opened and closed in the front-rear direction by rotating around the hinge 17, and the impact and sound at closing can be mitigated by adjusting the door closer 18. In addition, the opening direction of the hinged door 11 is not only the structure which opens toward the outdoor 10 side as shown in FIG. 2, but the structure which opens toward the entrance hall 3 side, or both the outdoor 10 side and the entrance hall 3 side. An open configuration is also possible. Although not shown in detail in the figure, the hinged door 11 is configured as a so-called double door in which two door plates open and close in the front-rear direction, or as a so-called parent-child door in which the width of the two door plates is different in size. It is also possible to configure.

  The sliding door 12 is a door for going back and forth between the entrance hall 3 and the adjacent room 4. Here, FIG. 4 is a schematic longitudinal sectional view in which the lower end portion of the sliding door 12 is enlarged. As shown in FIGS. 2 and 4, the sliding door 12 includes a door plate 14 provided with a daylighting window 19, a handle 20 for opening / closing operation respectively attached to both front and back surfaces of the door plate 14, and a lower end portion of the door plate 14. And a plurality of door wheels 21 that are rotatably supported by the shaft. In the sliding door 12 configured in this manner, each door wheel 21 is fitted to a rail 22 having a concave longitudinal section laid on the floor 7, and each door wheel 21 rolls along the rail 22. As shown by the arrows in FIG. 2, it can be opened and closed by sliding in the left-right direction. And, according to such a structure of the sliding door 12, the gap 23 between the lower end portion of the door plate 14 and the floor 7 is narrow, and the entrance is compared with the hinged door 11 in which a gap of a predetermined width is provided between the floor 7. Since the airtightness of the hall 3 is further increased, the atmospheric pressure fluctuation is likely to occur in the entrance hall 3 by opening and closing the hinged door 11. Further, when the door pulley 21 is fitted to the rail 22, a slight play 24 is provided between the two so that the door wheel 21 can smoothly roll, and thus the sliding door 12 is likely to be rattled for 24 minutes. . In this embodiment, the sliding door 12 will be described as an example of the joinery according to the present invention. However, other joinery having a configuration in which the gap between the floor 7 and the floor 7 is narrowed by sliding in the left-right direction in the same manner, for example, It may be a window, a bran or a shoji screen.

  The ventilation duct 5 is for ventilating the inside and outside of the entrance hall 3. The ventilation duct 5 is a tubular member made of metal, resin, or the like, and as shown in FIG. 1, the ventilation duct 5 is disposed on the ceiling back 25, and one end opening is formed in the ceiling 8 of the entrance hall 3. The other end opening 16 is connected to a vent hole 26 formed in the ceiling 8 of the adjacent chamber 4. In the present embodiment, the ventilation duct 5 is disposed in the ceiling back 25, but is not limited thereto, and may be disposed in the wall 9 or under the floor 27, for example. In addition, the position where the one end side of the ventilation duct 5 in the entrance hall 3 is connected as close as possible to the hinged door 11 makes it difficult for the sliding door 12 to be affected by atmospheric pressure fluctuations generated in the entrance hall 3 by opening and closing the hinged door 11. Therefore, it is preferable. Furthermore, it is sufficient that the other end of the ventilation duct 5 is connected to the outside of the entrance hall 3, and the vent duct 5 may be open to the ceiling 25 or the floor 27 without extending to the adjacent room 4, or connected to the outdoor 10. May be.

  The atmospheric pressure fluctuation suppression valve 6 is for suppressing the occurrence of an atmospheric pressure difference between the inside and outside of the entrance hall 3 by opening and closing the hinged door 11. Here, FIG. 5 is a partially enlarged longitudinal sectional view in which the periphery of the atmospheric pressure fluctuation suppression valve 6 in the ventilation duct 5 is enlarged. The atmospheric pressure fluctuation suppression valve 6 has a shape that substantially matches the shape of the internal cavity 28 of the ventilation duct 5, and an upper end portion 29 of the pressure fluctuation suppression valve 6 is fixed to the inside of the ventilation duct 5. Each can be bent toward both sides. According to such a configuration, when the air pressures on both sides across the air pressure fluctuation suppression valve 6 are equal, that is, when the hinged door 11 is in a closed state or opened state, and the air pressure inside and outside the entrance hall 3 is equal. The atmospheric pressure fluctuation suppression valve 6 is maintained in a vertical posture by its own weight without receiving an external force, and closes the internal cavity 28 of the ventilation duct 5. Thereby, while ensuring the airtightness of the adjacent room 4 and maintaining favorable air-conditioning efficiency, the soundproofing property of the adjacent room 4 can also be ensured.

  On the other hand, when there is a difference between the pressures on both sides of the air pressure fluctuation suppression valve 6, that is, when the hinged door 11 is opened and closed, and the pressure inside the entrance hall 3 is instantaneously higher or lower than the outside pressure. By receiving a force from the air flow generated from the high pressure side to the low pressure side, as shown by a dotted line in FIG. 5, the atmospheric pressure fluctuation suppression valve 6 bends with its upper end portion 29 as a fulcrum, and the ventilation duct 5 The internal cavity 28 is opened. As a result, when the pressure inside the entrance hall 3 becomes lower than the outside pressure at the moment when the hinged door 11 is opened, the air pressure fluctuation suppression valve 6 bends toward the inside of the entrance hall 3 and the outside air passes through the ventilation duct 5. By flowing into the entrance hall 3 through the air pressure, the air pressure inside the entrance hall 3 becomes equal to the external air pressure. On the contrary, when the pressure inside the entrance hall 3 becomes higher than the outside pressure at the moment when the hinged door 11 is closed, the air pressure fluctuation suppression valve 6 bends to the outside of the entrance hall 3 and the air inside the entrance hall 3 is changed. By flowing out through the ventilation duct 5, the pressure inside the entrance hall 3 becomes equal to the pressure outside. In this way, it is possible to prevent rattling noises and impacts from being caused by vibrations of the fittings such as the sliding door 12 by suppressing the sudden fluctuation in atmospheric pressure in the entrance hall 3. In addition, the structure of the atmospheric pressure fluctuation suppression valve 6 is not limited to the present embodiment, and a conventionally known valve structure that opens and closes depending on an atmospheric pressure difference can be employed.

  Next, a joinery vibration suppressing structure according to a second embodiment of the present invention will be described with reference to the drawings. The joinery vibration suppressing structure according to the present embodiment is provided in the door closer 18 to detect the opening / closing speed of the hinged door 11 (not shown), and provided in the lower end portion of the hinged door 11 to the interior of the entrance hall 3. And a ventilation mechanism for venting or isolating the outside. Here, FIG. 6 is a view showing the ventilation mechanism 30 according to the present embodiment, and is a partially enlarged front view in which the lower end portion of the hinged door 11 in FIG. 3 is enlarged. The entrance hall 3 according to the present embodiment differs from the entrance hall 3 according to the first embodiment shown in FIG. 2 only in the configuration around the hinged door 11, and other configurations such as the sliding door 12 are the first. Since it is the same as 1st Example, the same code | symbol as 1st Example is used and detailed description is abbreviate | omitted here.

  As shown in FIG. 6, the ventilation mechanism 30 is provided with a gap adjusting member 32 that opens or closes the gap 31 between the door plate 14 and the floor 7 so as to be able to protrude from the lower end portion of the door plate 14. More specifically, the door plate 14 of the hinged door 11 according to the present embodiment is formed so that its height dimension is slightly smaller than the height dimension of the opening 16 formed in the wall 9, and as shown in FIG. It is fixed to the wall 9 via a hinge 17 so as to leave a slight gap 31 between the lower edge 33 and the floor 7. The gap adjusting member 32 is formed to be wider than the gap 31 and is controlled to open or block the gap 31 by projecting and descending from the lower end of the door plate 14 in response to a signal from the opening / closing speed detection sensor. Yes. That is, while the opening / closing speed of the hinged door 11 detected by the opening / closing speed detection sensor does not reach a predetermined value, the gap adjustment member 32 protrudes from the lower end of the door plate 14 as shown in FIG. The gap 31 is blocked. On the other hand, when the opening / closing speed of the hinged door 11 exceeds a predetermined value, the gap adjusting member 32 enters the inside of the door plate 14 and opens the gap 31 as shown in FIG.

  According to such a structure, when the hinged door 11 is closed, the gap 31 is blocked by the gap adjusting member 32 and the airtightness of the entrance hall 3 is maintained. On the other hand, when the opening operation is started by grasping the handle 15 of the hinged door 11 in the closed state, the gap adjusting member 32 opens the gap 31 when the opening speed reaches a predetermined value. Thereby, even if the air inside the entrance hall 3 flows out to the outside with the subsequent opening operation, the outside air flows into the entrance hall 3 through the gap 31, so that the entrance hall 3 The air pressure inside the water does not drop rapidly. Therefore, at the moment when the hinged door 11 is opened, it is possible to prevent the fittings such as the sliding door 12 from vibrating and causing rattling noises or impacts. Thereafter, in a state where the hinged door 11 is completely opened and stopped, the gap adjusting member 32 protrudes from the lower end portion of the door plate 14.

  Next, when the closing operation is started by grasping the handle 15 of the opened door 11 in the opened state, the gap adjusting member 32 opens the gap 31 when the closing speed reaches a predetermined value. Thereby, even if outside air flows into the entrance hall 3 with the subsequent closing operation, the inside air of the entrance hall 3 flows out to the outside through the gap 31. The air pressure inside the water does not rise rapidly. Therefore, at the moment when the hinged door 11 is closed, it is possible to prevent the fittings such as the sliding door 12 from vibrating and generating a rattling sound or an impact. After that, when the hinged door 11 is closed again, the gap 31 is blocked by the gap adjusting member 32 and the entrance hall 3 becomes airtight.

  In this embodiment, the gap 31 is formed between the lower edge 33 of the door plate 14 and the floor 7, and the gap adjustment member 32 protrudes from the lower end of the door plate 14. It is good also as a structure which forms a clearance gap (not shown) between the upper end edge of this, and the wall 9, and the clearance gap adjustment member 32 protrudes and protrudes from the upper end part of the doorplate 14. FIG. Furthermore, in the present embodiment, the gap adjusting member 32 is protruded from the door plate 14, but the gap adjusting member 32 may be protruded from the floor 7 or the wall 9 instead.

  In this embodiment, the opening / closing speed detection sensor is provided in the door closer 18, but it may be provided in the door plate 14 or the wall 9 as long as the opening / closing speed of the hinged door 11 can be detected. Further, in this embodiment, the ventilation mechanism 30 is controlled so as to be electrically interlocked with the opening / closing operation of the hinged door 11, but instead, the ventilation mechanism 30 is mechanically interlocked with the opening / closing operation of the hinged door 11. Operation control may be performed. That is, although not shown in detail in the figure, when the sliding door 12 is provided with a door knob and a door handle for opening and closing, and when these are grasped and turned, the gap adjusting member 32 is interlocked via a conventionally known crank mechanism or the like. It is also possible to configure. Further, in the present embodiment, the opening / closing speed of the hinged door 11 is used as a trigger for controlling the operation of the ventilation mechanism 30, but it is also possible to use, for example, the presence or absence of a person around the hinged door 11. That is, although details are not shown in the figure, human detection sensors for detecting the presence or absence of humans are installed on the entrance hall 3 side and the outdoor 10 side of the hinged door 11 by means of conventionally known thermal sensors, infrared sensors, etc. While detecting the gap, the gap adjusting member 32 is immersed in the door plate 14 to open the gap 31. When the presence of a person is not detected, the gap adjusting member 32 protrudes from the door plate 14 to block the gap 31. It is also possible to configure so as to. In addition, by providing a lock mechanism that locks the ventilation mechanism 30 so that it cannot be opened and closed, and interlocking this with the locking mechanism of the hinged door 11 itself, when the hinged door 11 is locked so that it cannot be opened and closed, the ventilation mechanism 30 is also locked so that it cannot be opened and closed. This is preferable from the viewpoint of crime prevention.

  Next, a joinery vibration suppressing structure according to a third embodiment of the present invention will be described with reference to the drawings. The joinery vibration suppression structure according to the present embodiment is provided in the door closer 18 to detect an opening / closing speed detection sensor (not shown) for detecting the opening / closing speed of the hinged door 11, and is provided at the side end of the hinged door 11 to A ventilation mechanism that ventilates or isolates the inside and the outside is provided. Here, FIG. 7 is a view showing the ventilation mechanism 40 according to the present embodiment, and is a partially enlarged front view in which the right end portion of the hinged door 11 in FIG. 3 is enlarged. The entrance hall 3 according to the present embodiment differs from the entrance hall 3 according to the first embodiment shown in FIG. 2 only in the configuration around the hinged door 11, and other configurations such as the sliding door 12 are the first. Since it is the same as 1st Example, the same code | symbol as 1st Example is used and detailed description is abbreviate | omitted here.

  The ventilation mechanism 40 is provided with a gap adjusting member 42 that opens or closes the gap 41 between the door plate 14 and the wall 9 so as to be able to protrude from the side end portion of the door plate 14. More specifically, the door plate 14 of the hinged door 11 according to the present embodiment has a width dimension slightly smaller than the width dimension of the opening 16 formed in the wall 9, and as shown in FIG. It is fixed to the wall 9 via a hinge 17 so as to leave a slight gap 41 between the edge 43 and the wall 9. The gap adjusting member 42 is formed wider than the gap 41, and is controlled to open or block the gap 41 by protruding from the right end of the door plate 14 according to a signal from the opening / closing speed detection sensor. ing. That is, while the opening / closing speed of the hinged door 11 detected by the opening / closing speed detection sensor does not reach a predetermined value, the gap adjustment member 42 protrudes from the right end of the door plate 14 as shown in FIG. The gap 41 is blocked. On the other hand, when the opening / closing speed of the hinged door 11 exceeds a predetermined value, the gap adjusting member 42 is immersed in the door plate 14 and opens the gap 41 as shown in FIG. Here, since the effect which such a structure has is the same as that of the second embodiment, the description thereof is omitted here.

  In the present embodiment, the gap 41 is formed between the right edge 43 of the door plate 14 and the wall 9, and the gap adjusting member 42 protrudes and protrudes from the right edge of the door plate 14, but instead, A gap (not shown) may be formed between the left edge of the door plate 14 and the wall 9, and the gap adjustment member 42 may protrude from the left edge of the door plate 14. Further, in the present embodiment, the gap adjusting member 42 is protruded from the door plate 14, but the gap adjusting member 42 may be protruded from the wall 9 instead. In addition, the installation position of the opening / closing speed detection sensor may be the door plate 14 or the wall 9, the ventilation mechanism 40 may be mechanically linked to the opening / closing operation of the opening door 11, and a trigger for controlling the operation of the ventilation mechanism 40.

  Next, a joinery vibration suppressing structure according to a fourth embodiment of the present invention will be described with reference to the drawings. The joinery vibration suppressing structure according to the present embodiment includes a ventilation mechanism that ventilates or isolates the inside and outside of the entrance hall 3. The entrance hall 3 according to the present embodiment differs from the entrance hall 3 according to the first embodiment shown in FIG. 2 only in the configuration around the hinged door 11, and other configurations such as the sliding door 12 are the first. Since it is the same as 1st Example, the same code | symbol as 1st Example is used and detailed description is abbreviate | omitted here.

  Here, FIGS. 8 and 9 are views showing the ventilation mechanism 50 according to the present embodiment. The ventilation mechanism 50 includes a main door 51 having a large width and configured as an open door, a child door 52 having a small width and configured as a sliding door, and an opening / closing speed detection sensor (not shown) for detecting the opening / closing speed of the main door. It has. One end in the width direction of the main door 51 is fixed to the wall 9a via a hinge 53, and can be opened and closed in the front-rear direction by rotating around the hinge 53 as a fulcrum. On the other hand, the child door 52 is provided so as to be slidable along a rail 54 laid on the floor 7, and is controlled so as to appear and disappear from a door pocket 55 provided on the wall 9b in response to a signal from the opening / closing speed detection sensor. ing. That is, the child door 52 protrudes from the door pocket 55 while the opening / closing speed of the main door 51 detected by the opening / closing speed detection sensor does not reach a predetermined value. On the other hand, when the opening / closing speed of the main door 51 exceeds a predetermined value, the sub door 52 slides and is accommodated in the door pocket 55.

  According to the ventilation mechanism 50 configured as described above, as shown in FIG. 8A, when the main door 51 is completely opened, the child door 52 is completely protruded from the door pocket 55. When the closing operation of the main door 51 is started from this state, when the closing speed reaches a predetermined value, the child door 52 starts to slide in the direction of the door pocket 55 as shown in FIG. A part of the gap 56 between 51 and the wall 9b is opened. As a result, even if external air flows into the entrance hall 3 along with the subsequent closing operation of the main door 51, the air inside the entrance hall 3 flows out through the gap 56 to the outside. The air pressure inside the entrance hall 3 does not rise rapidly. Therefore, at the moment when the main door 51 is closed, it is possible to prevent the fittings such as the sliding door 12 from vibrating and causing rattling noises or impacts. Thereafter, when the main door 51 is completely closed as shown in FIG. 9A, the sub door 52 starts to slide toward the main door 51, and the sub door 52 is moved as shown in FIG. 9B. By completely closing the gap 56, the entrance hall 3 becomes airtight.

  In this embodiment, the operation of closing the main door 51 has been described. However, even when the main door 51 is opened, the child door 52 is slid to the door pocket 55 side when the opening speed of the main door 51 reaches a predetermined value. Thus, by partially opening the gap 56, it is possible to obtain the same effect as that during the closing operation. In addition, the ventilation mechanism 50 may be mechanically interlocked with the opening / closing operation of the main door 51, the human detection sensor may be installed as a trigger for controlling the operation of the ventilation mechanism 50, and the child door 52. It is the same as in the second embodiment that a lock mechanism for locking the door to be opened and closed is suitable for crime prevention if the lock mechanism is interlocked with the lock mechanism of the main door 51 itself.

  Next, a joinery vibration suppressing structure according to a fifth embodiment of the present invention will be described with reference to the drawings. The joinery vibration suppression structure according to the present embodiment is provided in the door closer 18 and is provided in an opening / closing speed detection sensor (not shown) for detecting the opening / closing speed of the hinged door 11, and in the daylighting window 13 of the hinged door 11. 3 is provided with a ventilation mechanism that ventilates or isolates the inside and the outside. Here, FIG. 10 is a view showing the ventilation mechanism 60 according to the present embodiment, and is a partially enlarged front view in which the daylighting window 13 of the hinged door 11 in FIG. 3 is enlarged. The entrance hall 3 according to the present embodiment differs from the entrance hall 3 according to the first embodiment shown in FIG. 2 only in the configuration around the hinged door 11, and other configurations such as the sliding door 12 are the first. Since it is the same as 1st Example, the same code | symbol as 1st Example is used and detailed description is abbreviate | omitted here.

  The ventilation mechanism 60 is configured to be able to open and close the daylighting window 13 provided on the door plate 14. That is, in the daylighting window 13, a transparent window glass (window adjusting member) 62 for taking in external light from the ventilating window 61 formed through the doorboard 14 protrudes and appears from the doorboard 14. The ventilation window 61 is provided so as to be blocked or opened. That is, the window glass 62 protrudes from the door plate 14 as shown in FIG. 10 (a) and opens the ventilation window 61 while the opening / closing speed of the hinged door 11 detected by the opening / closing speed detection sensor does not reach a predetermined value. Blocked. On the other hand, when the opening / closing speed of the hinged door 11 exceeds a predetermined value, the window glass 62 immerses into the door plate 14 and opens the ventilation window 61 as shown in FIG. Here, since the effect which such a structure has is the same as that of the second embodiment, the description thereof is omitted here.

  In addition, the formation position, the number, and the shape of the ventilation window 61 in the door plate 14, the opening / closing method of the window glass 62, and the like can be appropriately changed. For example, the opening / closing method of the window glass 62 may be a method using a hinge 63 as shown in FIG. 11 (a), or a method using a bendable arm member 64 as shown in FIG. 11 (b). . Further, the installation position of the opening / closing speed detection sensor may be the door plate 14 or the wall 9, the ventilation mechanism 60 may be mechanically linked to the opening / closing operation of the opening door 11, and a trigger for controlling the operation of the ventilation mechanism 60. As for the point that a human detection sensor may be installed as well as the fact that a locking mechanism that locks the ventilation mechanism 60 so that it cannot be opened and closed and interlocked with the locking mechanism of the hinged door 11 itself is suitable for crime prevention. Similar to the example. Furthermore, in the present embodiment, the ventilation window 61 is formed on the door plate 14 of the sliding door 12, but the ventilation window 61 may be formed on the wall 9, the floor 7, or the ceiling 8. In this case, it is preferable that the position where the ventilation window 61 is formed is as close as possible to the hinged door 11 because the fitting is less likely to be affected by atmospheric pressure fluctuations generated in the entrance hall 3 by opening and closing the hinged door 11.

  In addition, if the joinery vibration suppression structure according to the present invention is a space isolated from the outside by a partition wall, not only the entrance hall 3 of the house 2 but also, for example, an open space or an indoor closed space Can also be applied. The joinery vibration structure according to the present invention can be applied not only in the house 2 but also in a space isolated from the outside, for example, in an office building. Further, instead of ventilating the inside and outside of the entrance hall 3 with the ventilation duct 5 and the ventilation mechanisms 30, 40, 50, 60, the interior of the entrance hall 3 is used by using a pump or the like in conjunction with opening / closing of the hinged door 11. The atmospheric pressure may be adjusted.

  The joinery vibration suppression structure according to the present invention can also be appropriately combined with the above embodiments.
