Description

  The present invention is an open door-type door device that is installed in entrances and passages of buildings, machine rooms, underground passages, etc., and prevents inundation from the entrances and exits in an emergency such as heavy rain or flooding, and elastic used for such door devices. It relates to materials.

  A door device that constitutes an opening door generally includes a rectangular door body and a quadrilateral frame body that supports the door body with a hinge or the like. One door device is airtight. FIG. 12 is a schematic cross-sectional view of an example of a conventional door device having airtightness. In the figure, 1 is a door body, 2 is a frame body, 3 is a recess, 4 is an elastic material, and 5 is a pressing member. A pressing member 5 that protrudes inward is provided on the outer peripheral portion of the door body 1. Further, a recessed portion 3 is provided in a portion of the frame body 2 facing the outer peripheral portion of the door body 1, and an elastic material 4 is fitted in the recessed portion 3. When the door body 1 is closed, the pressing member 5 of the door body 1 comes into contact with the elastic material 4, and the pressing member 5 presses the elastic material 4. At this time, a latch (not shown) provided on the door body 1 is applied to the frame body 2, so that repulsion of the elastic material 4 is suppressed and the state in which the pressing member 5 presses the elastic material 4 is maintained. The elastic material 4 is deformed by the pressing of the pressing member 5 of the door body 1 to ensure airtightness and obtain sound insulation and heat insulation effects. Moreover, in the state which opened the door body 1, it has an elastic force of the grade which the elastic material 4 restores.

  On the other hand, in recent years, heavy rains, floods, and the like have occurred frequently, and watertightness is also required for door devices. As described above, the elastic member 4 is deformed by the pressing of the pressing member 5 to obtain airtightness. However, when water enters the gap between the door body 1 and the frame body 2, the water enters the inner side of the slight gap generated between the elastic member 4 and the pressing member 5 of the door body 1 due to the water pressure. End up. Therefore, the conventional door device having airtightness does not have high watertightness.

  Apart from the airtight door device, a watertight door device has also been developed. For example, in the door device described in Patent Document 1, the edge member provided on the inner periphery of the door and the seal member provided on the frame are brought into contact with each other, and the pulling handle device is further rotated. Thus, the edge member and the seal member are strongly pressed to obtain water tightness. In many door devices having water tightness that have been developed conventionally, water tightness is obtained by press-contacting the door and the frame in this manner.

  However, in such a door device having water tightness, a special configuration for strongly pressing the door body and the frame body is necessary, and a force required for the pressing must be applied. In addition, there is a case where it is not in time for an emergency because an operation for such press contact is necessary. In addition, if the operation of pressing is not performed, there may be a case where water has already infiltrated without noticing. In addition, there is a problem in that a handle for pressure welding is required and a door that can withstand pressure welding is required, and the design is poor.

  Even in the airtight door device shown in FIG. 12, it is conceivable that the pressing member 5 of the door body 1 is strongly pressed against the elastic material 4 to reduce the intrusion of water. As a result, the force for pressing the pressing member 5 against the frame 2 is increased, making it difficult to open and close.

  As an example of another door device having water tightness, there is one described in Patent Document 2. In this example, the watertight members are arranged in two stages, and the door body having a step at the end and the two stages of the watertight members are brought into surface contact with each other to obtain watertightness. In this configuration, a large force is not required because it is not pressed so much, but a space for arranging multi-stage watertight members on the door body and frame body is necessary, and a special structure for arranging them is necessary. Met.

  1 is a front view showing a first embodiment of the door device of the present invention, FIG. 2 is an AA ′ enlarged sectional view, and FIG. 3 is a sectional view showing an embodiment of an elastic material. . In the figure, 11 is a door device, 12 is a door body, 13 is a frame body, 21 is an outer surface of the door body, 22 is an inner surface of the door body, 23 is a side surface of the door body, 24 is a pressing member, 31 is a recess, and 32 is an elastic material. , 41 is an elastic part, 42 is a flexible part, 43 is a base part, and 44 is an elastic part. The example shown in FIG. 1 shows an example of a single-open door device.

  The door device 11 includes a rectangular door body 12 and a quadrilateral frame body 13 that supports the door body 12 with a hinge or the like. The door body 12 is provided with a pressing member 24 that protrudes from the door body inner surface 22 on the frame body 13 side. In this example, the pressing member 24 is provided on the outer periphery of the four circumferences of the inner surface 22 of the door body.

  The frame body 13 is provided with a recess 31 at a portion facing the outer periphery of the four circumferences of the door body inner surface 22, and an elastic material 32 is fitted in the recess 31. The elastic member 32 is provided so that the pressing member 24 protruding from the door inner surface 22 and the elastic member 32 come into contact with each other when the door member 12 is closed.

  An example of the elastic member 32 is shown in cross section in FIG. The elastic member 32 is provided with an elastic part 41, a flexible part 42, a base part 43, an elastic part 44, and the like. In the example shown in FIG. 3, the base portion 43, the flexible portion 42, and the elastic portion 44 are integrally formed, and the elastic portion 41 is joined to the base portion 43. Such an elastic material 32 is fitted into the recess 31 provided in the frame 13. When fitted, the bottom surface of the elastic material 32 is preferably in contact with the bottom surface of the recess 31 or is pressed by the elastic force of the elastic material 32. Of course, the bottom surface of the elastic member 32 and the bottom surface of the recess 31 may be bonded.

  When the door body 12 is closed, the elastic portion 41 comes into contact with the pressing member 24 protruding from the door body inner surface 22 and is further pressed. At this time, a locking device (not shown) may be provided on the door body 12, and the state where the elastic portion 41 is pressed by the pressing member 24 is maintained by the locking device being hooked on the frame body 13. Airtightness is ensured by the pressing force by the pressing member 24 and the elastic force of the elastic portion 41, and sound insulation and heat insulation effects are obtained. In addition, this pressing force and elastic force can provide a certain level of waterproofing effect, but may not have watertightness when subjected to water pressure. The elastic portion 41 is deformed by being pressed by the pressing member 24 when the door body 12 is closed as described above, and has returned to its original shape when the door body 12 is opened. Desired. Therefore, the elastic portion 41 is required to have a high restoring force although it is easily deformed by the pressing force. For example, a material having a relatively low hardness, a large thickness, and a high repulsive force may be used as the elastic portion 41.

  The flexible portion 42 has flexibility and is preferably more flexible than the material used for the elastic material 32. Further, the distal end portion of the flexible portion 42 may be directed outward in order to prevent the flexible portion 42 from undergoing unexpected deformation when the door body 12 is closed. When the door body 12 is closed, the flexible portion 42 abuts or approaches the pressing member 24 or the door body side surface 23 provided on the door body 12, and the abutting portion between the elastic portion 41 and the pressing member 24 is formed. The flexible part 42 covers. When water enters from a gap between the frame body 13 and the door body 12 from the outside, the flexible portion 42 is deformed to the door body side face 23 side by the pressure of the water. As the water pressure increases, the flexible portion 42 comes into pressure contact with the pressing member 24 and the door body side surface 23, and the water stop performance is improved by this pressure contact, preventing water from entering inside. Even if water enters between the distal end of the flexible portion 42 and the pressing member 24 or the door body side surface 23, the flexible portion 42 is pressed against the surface by the pulling pressure when the water escapes to the inside. The flexible portion 42 is pressed against the pressing member 24 and the door body side surface 23 by water that is pressed against the member 24 and the door body side surface 23 and further enters. This prevents water from entering the interior. Furthermore, since the flexible part 42 also covers the joint part of the elastic part 41 and the base part 43 in the case of water immersion, the water immersion from this joint part can also be prevented.

  The distal end portion of the flexible portion 42 is located away from the position of the door body side surface 23 when the door body 12 is closed, and the pressing member 24 contacts the elastic portion 41 so that the elastic portion 41 and the base portion 43 are Along with the deformation, the flexible portion 42 approaches or further abuts the door body side surface 23. In this case, the flexible portion 42 is not caught when the door 12 is closed. Further, even when the flexible portion 42 abuts against the door body side face 23 and the pressing member 24 in a state in which the door body 12 is closed, the force for closing the door body 12 does not increase.

  The elastic portion 44 abuts against the side surface of the concave portion 31 when the elastic material 32 is fitted into the concave portion 31 of the frame body 13, and the elastic material 32 makes it difficult for the elastic material 32 to escape from the concave portion 31. Further, the water that enters the recess 13 of the frame 13 and tries to enter is prevented together with the contact portion between the bottom surface of the base portion 43 and the recess 31. The elastic portion 44 is a common elastic material fixing method, and when other fixing methods such as adhesive fixing are used, the elastic portion 44 may be omitted.

  As described above, the flexible portion 42 and the elastic portion 44 are integrally formed on the base portion 43 in this example. When the elastic portion 41 is deformed by the pressing force of the pressing member 24 of the door body 12, the base portion 43 is also deformed. Due to the deformation of the base portion 43, the flexible portion 42 comes close to or further abuts on the door body side surface 23 and the pressing member 24. Therefore, a material having elasticity is also used for the base portion 43. In this example, the flexible portion 42 formed integrally with the base portion 43 is thin because it has flexibility as described above. Therefore, it is preferable to have a certain degree of hardness while having elasticity, and such a material is also used for the base portion 43. For example, an elastic material such as rubber having higher hardness than the elastic portion 41 may be used. In the example shown in FIG. 3, the elastic member 32 is formed by joining the elastic portion 41 and the base portion 43 having different materials such as hardness.

  FIG. 4 is a cross-sectional view illustrating a modification of the elastic material according to the embodiment. The reference numerals in the figure are those shown in FIG. 3, and different points will be mainly described. In the example of the elastic member 32 shown in FIG. 4, the elastic portion 41 and the flexible portion 42 are integrally formed, the base portion 43 and the elastic portion 44 are integrally formed, and the elastic portion 41 and the base portion 43 are joined. It is configured. In this case, since the elastic part 41 and the flexible part 42 are formed of the same material, it is manufactured by adjusting the hardness of the material and the thickness of each part.

  In the case of the example shown in FIG. 4, the flexible portion 42 is close to the pressing member 24 and the door body side surface 23 due to the deformation of the elastic portion 41 caused by the pressing member 24 pressing the elastic portion 41. Or it contacts further. When the elastic portion 41 is deformed by the pressing of the pressing member 24, the deformation of the base portion 43 is not essential. However, if the base portion 43 is also deformed, the flexible portion 42 can be easily brought close to the pressing member 24 or the door body side surface 23. Or even more easily.

  FIG. 5 is a cross-sectional view showing another modification of the embodiment of the elastic material. The reference numerals in the figure are those shown in FIG. 3, and different points will be mainly described. In the example of the elastic material 32 shown in FIG. 5, the whole is integrally formed. Also in this case, since the elastic part 41 and the flexible part 42 are formed of the same material, it is manufactured by adjusting the hardness of the material and the thickness of each part. In the example shown in FIG. 5B, the elastic portion 41 also serves as the base portion 43.

  In any of the examples shown in FIG. 5, the flexible portion 42 moves closer to the pressing member 24 and the door body side surface 23 due to the deformation of the elastic portion 41 caused by the pressing member 24 pressing the elastic portion 41. Or further abut. In the case of the example shown in FIG. 5A, when the elastic portion 41 is deformed by the pressing of the pressing member 24, the deformation of the base portion 43 is not essential, but if the base portion 43 is also deformed, the flexible portion 42 is pushed. It becomes easy to make it approach to the contact member 24 and the door body side surface 23, or it becomes easy to contact | abut further.

  Some examples of the elastic material 32 have been shown, but the elastic material 32 is not limited to these examples, and it goes without saying that various modifications may be used.

  FIG. 6 is an explanatory diagram showing an example of the state of the elastic body by opening and closing the door body in the first embodiment of the door device of the present invention. 6A shows a state where the door body 12 is opened, and FIG. 6B shows a state where the door body 12 is closed. As the elastic material 32, the case where the thing of the structure shown in FIG. 3 is used is shown.

  When the door body 12 is to be closed from the state where the door body 12 shown in FIG. 6A is open, the pressing member 24 protruding from the inner surface of the door body 12 is provided with the elastic member 32 provided on the frame body 13. The elastic member 32 is pressed against the elastic member 41 and the door member 12 is closed as shown in FIG. In this state, a locking device (not shown) provided on the door body 12 may be hung on the frame body 13. When locking is performed, the state in which the pressing member 24 presses the elastic member 32 is well maintained. Airtightness can be obtained by pressing the elastic portion 41 of the elastic member 32 by the pressing member 24.

  When the pressing member 24 presses the elastic material 32, the elastic material 32 is deformed. In this example, the elastic portion 41 of the elastic member 32 is greatly deformed by the pressing force of the pressing member 24 and the base portion 43 is also deformed. Due to the deformation of the base portion 43, the flexible portion 42 is inclined toward the door body 12, and in this example, the flexible portion 42 contacts the door body side surface 23 and the pressing member 24. Since the flexible portion 42 is configured to contact the door body side surface 23 and the pressing member 24, the force required for closing the door body 12 is comparable to that of a conventional door device having airtightness. Thus, strong pressure is not required as in the case of a door device having water tightness. Moreover, in this structure, the flexible part 42 can be made to contact | abut to the door body side surface 23 reliably by closing the door body 12. FIG. Furthermore, when closing the door body 12, the distal end of the flexible portion 42 facing outward does not cause unexpected deformation such as being caught by the door body side surface 23 or the pressing member 24.

  FIG. 7 is an explanatory diagram of an example of a state during the flooding in the first embodiment of the door device of the present invention. When water is immersed in a state in which the door body 12 is closed, water enters the gap between the door body 12 and the frame body 13. The water that has infiltrated pushes the flexible portion 42. At this time, since the flexible portion 42 is in contact with the door body side surface 23 and the pressing member 24, the flexible portion 42 Water enters between the frames 13.

  The flexible portion 42 is more flexible than the elastic portion 41, and the flexible portion 42 is bent and deformed toward the door body side surface 23 due to the pressing force of water during water immersion, so that the flexible portion 42 and the door are deformed. The body side surface 23 and the pressing member 24 are in close contact with each other. Furthermore, the flexible portion 42 is pressed against the door body side surface 23 and the pressing member 24 by increasing the pressure of the water that has entered.

  In addition, even when water enters the gap between the door body side surface 23 and the flexible portion 42, the flexible portion 42 bends toward the door body side surface 23 side by the pulling force when the infiltrated water spreads in the back, and the flexible portion 42, the door body side surface 23, and the pressing member 24 will contact | adhere. Thereby, watertightness is obtained and water stop performance can be improved. Furthermore, as the water pressure is higher, the degree of adhesion between the flexible portion 42 and the door body side surface 23 is increased, and high water stopping performance can be obtained. Therefore, unlike the conventional door device having water tightness, it is not necessary to press the outer peripheral portion of the inner surface 22 of the door body strongly against the waterproof rubber in advance.

  The door body 12 is pushed by the pressure of water, and the pressing member 24 that is in contact with the elastic portion 41 of the elastic member 32 may be slightly displaced to generate a gap. Even when such a gap occurs, the flexible portion 42 stops water in the vicinity of the pressing member 24 and the elastic member 32, so that stable water stopping performance can be maintained.

  The water that is about to enter between the frame 13 and the flexible portion 42 is also blocked by the error portion 44, the portion where the base portion 43 and the concave portion of the outside frame 13 are in contact, and the like, and it is difficult for water to enter the inside. It is a configuration. As described above, in the first embodiment of the present invention, the water stopping performance is improved and the water tightness is obtained by the simple configuration in which the elastic member 32 is provided with the flexible portion 42.

  In the example shown in FIG. 6, a configuration in which the flexible portion 42 of the elastic material 32 abuts against the door body side surface 23 and the pressing member 24 by closing the door body 12 is shown, but the door body 12 is closed. Therefore, the flexible portion 42 may be close to the door body side surface 23 or the pressing member 24. In this case, water enters the gap between the side surface 23 of the door body and the flexible portion 42, but the intruded water pulls the flexible portion 42 to the back when spreading at the back, and this pulling pressure and the frame 13 The flexible portion 42 is bent toward the side surface 23 of the door body by the pressing force applied to the flexible portion 42 by the water entering between the flexible portion 42 and the flexible portion 42, and the pressing member 24 abuts and comes into close contact. Further, the flexible portion 42 is pressed against the door body side surface 23 and the pressing member 24 by the pressure of water. In this way, even when the flexible portion 42 is close to the door body side surface 23 and the pressing member 24 with the door body 12 closed, as shown in FIG. The flexible portion 42 is brought into close contact with and pressed against the door body side surface 23 and the pressing member 24 to improve the water stopping performance, and the water tightness can be obtained to stop the water.

  Here, the case where the elastic member 32 having the structure shown in FIG. 3 is used has been described. However, the elastic member 32 having the structure shown in FIG. 4, the elastic member 33 having the structure shown in FIG. Even when the deformed elastic material 32 is used, water tightness is basically obtained by the above-described operation. Further, for example, as the elastic material of the conventional airtight door device shown in FIG. 12, various elastic materials 32 shown as one embodiment of the elastic material of the present invention in FIGS. By using or replacing the elastic material 32 that is appropriately deformed, the water stop performance can be improved even in a conventional door device having airtightness.

  FIG. 8 is an enlarged cross-sectional view showing a second embodiment of the door device of the present invention. In the figure, the same parts as those of the first embodiment are denoted by the same reference numerals and the description thereof is omitted. Reference numeral 14 denotes a first door body, 15 denotes a second door body, 33 denotes an elastic material, and 51 denotes a door receiving portion. In the second embodiment, a case of a double door device is shown. The door device 11 in the second embodiment has a rectangular first door body 14 and a second door body 15, and a four-round shape that supports the first door body 14 and the second door body 15 with a hinge or the like. It consists of a frame 13.

  As in the case of the single door device in the first embodiment, the frame body 13 is provided with a recess 31 at a portion facing the outer peripheral portions of the inner surfaces of the first door body 14 and the second door body 15. The elastic material 32 is fitted in the concave portion 31, and the elastic material 32 is provided to face the outer peripheral portions of the inner surfaces of the first door body 14 and the second door body. The elastic material 32 has been described in the first embodiment, and various elastic materials 32 shown in FIGS. 3, 4, and 5 or an elastic material 32 appropriately deformed can be used. Since the watertightness between the frame body 13 and the first door body 14 and between the frame body 13 and the second door body 15 is as described in the first embodiment, the description thereof is omitted here. To do.

  In the double door device, the pressing member 24 and the elastic member 32 are further provided at the mating portion of the first door body 14 and the second door body 15. In this example, the door receiving portion 51 is provided on the first door body 14 side, and the elastic material 33 is provided on the door receiving portion 51. The elastic material 33 may be the same as the elastic material 32 provided on the frame 13. Here, an example is shown in which the elastic material 32 having the structure shown in FIG. 3 is used. However, the elastic material 32 is not limited to this, and the elastic material 32 shown in FIGS. It may be used. The second door body 15 is provided with a pressing member 24 that protrudes from the inner surface of the second door body 15 at a position facing the door receiving portion 51 of the first door body 14.

  Before closing the second door body 15 with the first door body 14 closed, the tip of the flexible portion 42 is separated from the position of the side surface of the second door body 15 when the second door body 15 is closed. It is good to exist outwards at the position. When the second door body 15 is further closed with the first door body 14 closed, the pressing member 24 provided on the second door body 15 abuts against the elastic member 33 and is further elasticated by the pressing member 24. The material 33 is pressed. In the case where a locking device (not shown) is provided on the second door body 15, the pressing may be maintained by the locking device hanging on the frame body 13. The elastic member 33 is deformed by the pressing by the pressing member 24, and the flexible portion 42 provided on the elastic member 33 comes into contact with or approaches the side surface of the second door body 15 and the pressing member 24. Thereby, the flexible portion 42 is provided so as to cover the contact portion between the elastic portion 41 and the pressing member 24. With such a configuration, unexpected deformation such as the flexible portion 42 being caught when the second door body 15 is closed is not caused, and the flexible portion 42 is not attached to the second door body 15. Even when abutting against the side surface or the pressing member 24, the force for closing the second door body 15 does not increase.

  When water infiltrates from the outside, the above-mentioned first water is introduced between the first door body 14 and the frame body 13 and between the second door body 15 and the frame body 13. As described in the embodiment, the flexible portion 42 of the elastic member 32 provided in the frame body 13 is pressed against the side surface of the first door body 14 and the side surface of the second door body 15 by the pressure of water. Stop water. Further, when water enters the gap between the first door body 14 and the second door body 15 from the outside, the flexible portion 42 of the elastic member 33 provided on the first door body 14 causes the second door by the water pressure. The flexible portion 42 is pressed against the side surface of the second door body 15 and the pressing member 24 due to the deformation of the side surface of the body 15 and further water pressure. Even when water enters between the second door body 15 and the flexible portion 42, the flexible portion 42 is deformed by the pulling pressure of the water that has entered the back portion, and is applied to the side surface of the second door body 15 and the pressing member 24. The flexible portion 42 is further pressed against the side surface of the second door 15 and the pressing member 24 by the pressing force of the water that is in pressure contact and enters between the first door body 14 and the flexible portion 42. Such pressure contact improves the water stopping performance and prevents water from entering through the gap between the first door body 14 and the second door body 15. Even when water pressure is applied to the first door body 14 and the second door body 15 and the pressing member 24 and the elastic member 41 are displaced to form a gap, the flexible portion 42 covers the vicinity and stops the water. Therefore, stable water stop performance can be maintained.

  In this way, even in a double door device, water from the outside can be prevented.

  FIG. 9 is an enlarged sectional view showing a third embodiment of the door device of the present invention. In each above-mentioned embodiment, the flexible part 42 of the elastic materials 32 and 33 shows the example which contact | abuts or adjoins to the side surface of the door body 12, the 1st door body 14, and the 2nd door body 15, and the pressing member 24. It was. The present invention is not limited to this. In the third embodiment, an example is shown in which the flexible portion 42 is in contact with or close to the inner surfaces of the door body 12, the first door body 14, and the second door body 15. FIG. 9 shows an example of a single-open door device as an example. FIG. 9A shows a state in which the door body 12 is opened, and FIG. 9B shows a state in which the door body 12 is closed. Show. Note that description of the same parts as those in the first embodiment may be omitted.

  Also in the third embodiment, the door body 12 is provided with a pressing member 24 protruding from the door body inner surface 22. Further, a concave portion 31 is provided in a portion of the frame 13 that faces the pressing member 24, and the elastic member 32 is fitted into the concave portion 31. When the door body 12 is closed, the pressing member 24 becomes the elastic material. 32 elastic parts 41 are configured to be pressed. Further, in this embodiment, the concave portion 31 provided in the frame body 13 is arranged so that the flexible portion 42 of the elastic material 32 is disposed in contact with or close to the inner surface 22 of the door body when the door body 12 is closed. And the elastic material 32 is provided inside the above-mentioned each embodiment. In connection with this, the pressing member 24 provided in the door body 12 is also correspondingly provided inside the above-described embodiments.

  The flexible portion 42 of the elastic member 32 in the third embodiment is in contact with or close to the door body inner surface 22 when the door body 12 is closed, and the contact portion between the elastic portion 41 and the door body 12. Cover. The distal end of the flexible portion 42 may be directed toward the outer peripheral portion of the door body 12 in order to avoid unexpected deformation when the door body 12 is closed. The flexible portion 42 has flexibility and is preferably more flexible than the material used for the elastic portion 41. 9 shows the elastic material 32 having the structure shown in FIG. 3, the elastic material 32 shown in FIGS. 4 and 5 or an elastic material 32 obtained by appropriately deforming them may be used.

  When the door body 12 is closed, as shown in FIG. 9B, the pressing member 24 provided on the door body 12 comes into contact with the elastic portion 41 of the elastic material 32 provided on the frame body 13. The elastic material 32 is pressed. If a locking device (not shown) is provided on the door body 12, the pressing state is maintained by the locking device hanging on the frame body 13. When the pressing member 24 presses the elastic material 32, the elastic material 32 and the base portion 43 are deformed, and the flexible portion 42 contacts or approaches the door body inner surface 22 and the pressing member 24. As described in the first embodiment, the elastic portion 41 may be deformed so that the flexible portion 42 approaches or contacts the door body inner surface 22 and the pressing member 24, or the tip position of the flexible portion 42 is previously set. However, the flexible portion 42 may be brought close to or in contact with the inner surface 22 of the door body or the pressing member 24 regardless of the deformation of the elastic portion 41. If the flexible portion 42 is more flexible than the material used for the elastic portion 41, it is necessary to close the door body 12 even when the flexible portion 42 abuts against the door body inner surface 22 or the pressing member 24. The power is almost unchanged. Further, in the configuration in which the flexible portion 42 is brought into contact with or close to the inner surface 22 of the door body or the pressing member 24, unexpected deformation such as the winding of the flexible portion 42 caused by closing the door body 12 does not occur.

  When the door 12 is closed and the water is infiltrated into the gap between the door 12 and the frame 13, the flexible portion 42 is flexible. By the pressing force, the flexible portion 42 is bent and deformed toward the door body inner surface 22 side, and the flexible portion 42 and the door body inner surface 22 and the pressing member 24 are brought into close contact with each other. As the water pressure further increases, the flexible portion 42 is brought into pressure contact with the door body inner surface 22 and the pressing member 24. Further, even when water enters between the flexible portion 42 and the door body inner surface 22, the flexible portion 42 bends toward the door body inner surface 22 side by the pulling pressure caused by the entered water, and the flexible portion 42 and the door body inner surface 22. And the pressing member 24 are in close contact with each other. In this way, the flexible portion 42, the door body inner surface 22 and the pressing member 24 are in close contact with each other, water tightness is obtained, and water intrusion into the interior can be prevented. Furthermore, as the water pressure increases, the flexible portion 42 is pressed against the door body inner surface 22 and the pressing member 24 to increase the degree of adhesion between the two, and the water stop performance is improved. Further, even when the door body 12 is pushed by water pressure and the pressing member 24 is displaced and a gap is formed between the elastic part 41, the flexible part 42 is still water in the vicinity, and the stable water stop Performance can be maintained. Thus, also in the third embodiment, a door device having high water tightness can be provided with a simple configuration.

  In the example shown in FIG. 9, the configuration in which the flexible portion 42 of the elastic member 32 abuts against the door inner surface 22 and the pressing member 24 by closing the door body 12 is shown, but the door body 12 is closed. Thus, the flexible portion 42 may be close to the inner surface 22 of the door body or the pressing member 24. Also in this case, the flexible portion 42 is deformed by the pressing force and pulling pressure of the water that has entered, and comes into contact with and closely contacts the inner surface 22 of the door body and the pressing member 24. The door body side surface 23 and the pressing member 24 are brought into pressure contact with each other, water tightness is obtained, and water can be stopped.

  In addition, although FIG. 9 illustrates a single-open door device, the present invention is also applicable to the double-open door device shown in the second embodiment. In that case, the flexible portion 42 of the elastic member 33 provided on the door receiving portion 51 of the first door body 14 may be brought into contact with or close to the inner surface of the second door body 15. Thus, it is possible to prevent water from entering between the first door body 14 and the second door body 15 as well as between the frame body 13 and the first door body 14 and the second door body 15. Can prevent flooding.

  FIG. 10 is an enlarged cross-sectional view showing a fourth embodiment of the door device of the present invention. In the figure, the same parts as those of the first embodiment are denoted by the same reference numerals and the description thereof is omitted. 61 is an elastic material, 62 is a flexible material, and 63 is a protrusion. In the third embodiment, an example in which the flexible portion 42 provided in the elastic members 32 and 33 in each of the above-described embodiments is separated is shown. The example shown in FIG. 10 shows an example of a single-open door device. FIG. 10A shows a state in which the door body 12 is opened, and FIG. 10B shows a state in which the door body 12 is closed. , Respectively.

  An elastic material 61 is fitted into the concave portion 31 of the frame body 13, and the elastic material 61 is provided so as to face the outer peripheral portion of the inner surface 22 of the door body. When the door body 12 is closed, the pressing member 24 that protrudes from the inner surface 22 of the door body is brought into contact with and pressed against the elastic member 61. The elastic member 61 is not provided with the flexible portion 42 in this embodiment. For example, an elastic material used in a conventional door device having airtightness may be used.

  The frame 13 is provided with a flexible material 62 on the four circumferential surfaces facing the door body side surface 23. The flexible member 62 is preferably attached so that the tip thereof faces the outside so that unexpected deformation does not occur when the door body 12 is closed. A protruding portion 63 is provided in the middle of the flexible material 62, and this protruding portion 63 is in a position that comes into contact with the distal end portion of the pressing member 24 provided on the door body 12 when the door body 12 is closed. Be placed. The flexible material 62 is flexible particularly on the tip side of the protrusion 63.

  When the door body 12 is closed, the projection 63 is pushed to the inner side by the pressing member 24, and at the same time, the tip of the flexible material 62 moves toward the door body side surface 23, and the door body side surface 23 and the pressing member 24 are moved. Abut or close. The pressing member 24 abuts on the elastic material 61 and further presses the elastic material 61. If the door body 12 is provided with a locking device (not shown), the locking device is hooked on the frame body 13 so that the pressure is maintained well. Airtightness is obtained by pressing the elastic member 61 by the pressing member 24.

  The force required to push the projection 63 by the pressing member 24 and move the tip of the flexible material 62 is very small, and the force when closing the door body 12 does not increase so much. Further, in the configuration in which the protruding portion 63 is provided, the distal end of the flexible material 62 does not cause unexpected deformation such as being caught when the door body 12 is closed, and the distal end portion of the flexible material 62 is securely attached to the door. It can be brought into contact with or close to the body side surface 23.

  When water enters the gap between the frame body 13 and the door body 12 from the outside with the door body 12 closed, the tip side of the protrusion 63 of the flexible material 62 bends and deforms due to the pressure of the water. The flexible material 62 is pressed against the door body side face 23 and the pressing member 24 by further water pressure. This pressure contact improves water stopping performance and prevents water from entering inside. In addition, between the frame 13 and the flexible material 62, the flexible material 62 is bonded to the frame 13 and the flexible material 62 is pressed against the frame 13 by water pressure. Water can be stopped even at the part, preventing water from entering the interior. Further, even when water enters between the front end of the flexible material 62 and the door body side surface 23, it spreads and becomes a pulling pressure when the water enters further to the back, and the flexible material 62 has the door body side surface 23 or It can be pressed against the pressing member 24 to stop water. Further, even when the door body 12 is pushed by water pressure and the pressing member 24 is displaced and a gap is formed between the elastic member 61, the flexible member 62 is still stopped in the vicinity, and stable water stopping Performance can be maintained.

  In addition, although it showed about the single door apparatus here, it is applicable also to the double door apparatus similarly to 2nd Embodiment. For example, what is necessary is just to comprise so that the flexible material 62 may be provided in any one of the side surface of the 1st door body 14 and the 2nd door body 15 which oppose, and the front-end | tip part may contact | abut or adjoin to the other. Further, as shown in the third embodiment, the flexible member 62 may be provided so as to face the outer periphery of the four circumferences of the inner surface 22 of the door body.

  FIG. 11: is a cross-sectional enlarged view which shows the modification of 4th Embodiment of the door apparatus of this invention. In this modification, a configuration is shown in which the flexible member 62 in the fourth embodiment described above is provided on the door body 12 side. The example shown in FIG. 11 shows an example of a single-open door device. FIG. 11A shows a state in which the door body 12 is opened, and FIG. 11B shows a state in which the door body 12 is closed. , Respectively.

  In the modification of the fourth embodiment, a flexible material 62 is provided on the door body side surface 23. The flexible material 62 is flexible and may be attached so that the tip thereof faces outward so as not to be deformed unexpectedly. When the door body 12 is to be closed, the flexible material 62 comes into contact with the corner of the frame body 13 and moves so as to slide on the surface of the frame body 13 that faces the door body side surface 23 and faces the door body side surface 23. The state where the end portion of the flexible material 62 is in contact with the surface of the frame body 13 to be maintained is maintained.

  When water enters the gap between the frame body 13 and the door body 12 from the outside, the flexible material 62 is bent and deformed by the water pressure, and the surface of the frame body 13 facing the door body side surface 23 by further water pressure. The flexible material 62 is press-contacted. This pressure contact improves water stopping performance and prevents water from entering inside. In addition, between the door body side surface 23 and the flexible material 62, the flexible material 62 is attached to the frame 13 and the flexible material 62 is hydraulically attached to the door body side surface 23 and the pressing member 24. In this area, water is stopped even at this portion, and water can be prevented from entering inside. Further, even when the door body 12 is pushed by water pressure and the pressing member 24 is displaced and a gap is formed between the elastic member 61, the flexible member 62 is still stopped in the vicinity, and stable water stopping Performance can be maintained.

  Further, the front end of the flexible member 62 may not be in contact with the side surface of the frame body 13 in a state in which the door body 12 is closed. Also in this case, the flexible member 62 is deformed to the surface of the frame body 13 facing the door body side surface 23 by the water pressure of water entering the gap between the frame body 13 and the door body 12 from the outside. The flexible material 62 is pressed against the surface of the frame body 13. Even when water enters between the side surface of the frame body 13 and the tip of the flexible material 62, the flexible material 62 comes into close contact with the side surface of the frame body 13 due to the pulling force when the water advances. Further, the flexible material 62 is brought into pressure contact with the side surface of the frame body 13 by the water pressure entering between the door body side surface 23 and the flexible material 62. This improves the water stopping performance and prevents water from entering the interior. Further, even when the door body 12 is pushed by water pressure and the pressing member 24 is displaced and a gap is formed between the elastic member 61, the flexible member 62 is still stopped in the vicinity. The water stop performance can be maintained.

  In this example, a single-open door device is also shown, but the present invention can also be applied to a double-open door device as in the second embodiment. For example, the flexible material 62 may be provided on one of the side surface of the first door body 14 and the side surface of the second door body 15 that are opposed to each other, and the tip portion may be in contact with the other. In the fourth embodiment, the example in which the flexible material 62 is provided on the side surface of the door body 12 or the side surface of the frame body 13 facing the door body 12 is shown. However, as in the above-described third embodiment.
