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. 8 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, and 4 is an elastic material. A concave 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 into the concave portion 3. When the door body 1 is closed, the outer peripheral portion of the inner surface of the door body 1 comes into contact with and presses the elastic material 4. As a result, airtightness is ensured, and sound insulation and heat insulation effects are also obtained.

  On the other hand, in recent years, heavy rains, floods, and the like have occurred frequently, and watertightness is also required for door devices. In the door device having the above-described airtightness, the elastic member 4 has an elastic force that can be easily deformed by closing the door body 1, and is elastic with a wind pressure that enters the gap between the door body 1 and the frame body 2. The contact state between the material 4 and the door body 1 is not released. However, when water enters the gap between the door body 1 and the frame body 2, the contact state between the elastic member 4 and the door body 1 is released by the water pressure, and the water is immersed inside. Although it is conceivable that the door body 1 is strongly pressed against the elastic material 4 to reduce the intrusion of water, the force for pressing the door body 1 against the frame body 2 is increased during normal opening and closing. It becomes difficult.

  Watertight door devices have 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 brought into pressure contact to obtain watertightness. 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, the door device having such water tightness requires a special configuration for press-contacting the door body and the frame body, and a force required for press-contact 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.

  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 a door body outer surface, 22 is a door body inner surface, 23 is a door body side surface, 31 is a recess, 32 is an elastic material, 41 is an elastic portion, Reference numeral 42 denotes a flexible portion, 43 denotes a bottom portion, and 44 denotes an elastic portion. 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 frame body 13 is provided with a recess 31 at a portion of the door body inner surface 22 facing the outer periphery of the four circumferences. An elastic material 32 is fitted into the recess 31, and the elastic material 32 is placed on the outer periphery of the door body inner surface 22. It is provided facing.

  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 bottom part 43, an elastic part 44, and the like. When the door body 12 is closed, the elastic portion 41 comes into contact with the outer peripheral portion of the door body inner surface 22 and is pressed by the door body 12. As a result, airtightness is secured, and sound insulation and heat insulation effects are obtained. Moreover, although some waterproofing effects are acquired, it does not need to have the watertightness at the time of receiving a water pressure.

  The flexible portion 42 has flexibility and may be more flexible than the elastic material 32. When the door body 12 is closed, the flexible portion 42 is provided so as to cover or contact the door body side surface 23 and cover the contact portion between the elastic portion 41 and the door body 12. When water enters the gap between the frame body 13 and the door body 12 from the outside, the flexible portion 42 is brought into pressure contact with the door body side surface 23 by the pressure of the water. Water is stopped by this pressure contact to prevent water from entering inside.

  Note that 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 elastic material 32 is deformed as the door body 12 comes into contact with the elastic portion 41. Thus, the flexible portion 42 comes close to or further contacts the door body side surface 23. In this case, the flexible portion 42 is not caught when the door 12 is closed. Moreover, even when the flexible part 42 contacts the door body side surface 23, the force at the time of closing the door body 12 does not increase.

  The bottom 43 is fitted so as to face the bottom surface side of the recess 31 when the elastic member 32 is fitted into the recess 31 provided in the door body 12. The bottom 43 may be in contact with the bottom of the recess 31 or pressed by the elastic force of the elastic member 32. Of course, the bottom part 43 and the bottom face of the recessed part 31 may be adhere | attached. Further, the height of the elastic portion 41 can be adjusted by the bottom portion 43.

  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. In addition, water that tries to enter from the recess 31 of the frame 13 is prevented together with the bottom 43. If the error portion 44 is unnecessary, it may be configured without being provided.

  FIG. 4 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. 4A shows a state in which the door body 12 is opened, and FIG. 4B shows a state in which the door body 12 is closed. 4A, when the door 12 is to be closed from the opened state, the outer peripheral portion of the inner surface 22 of the door contacts the elastic portion 41 of the elastic member 32 provided on the frame 13. The elastic material 32 is pressed in contact, and the door 12 is closed as shown in FIG.

  When the door body 12 presses the elastic material 32, the elastic material 32 is deformed. Due to the deformation of the elastic material 32, 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. Since the flexible portion 42 is configured to contact the door body side surface 23, the force required to close the door body 12 is comparable to that of a conventional airtight door device or the like, and has conventional watertightness. Strong pressurization like a door device is unnecessary. 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 the door body 12 is closed, the flexible portion 42 is not caught in the door body side surface 23.

  FIG. 5 is an explanatory diagram showing an example of a state of water immersion 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, the water enters between the flexible portion 42 and the door body side surface 23 rather than between the flexible portion 42 and the frame body 13. The water will infiltrate.

  Then, the flexible portion 42 is pressed against the door body side surface 23 by the pressure of the water that has entered. The flexible portion 42 is more flexible than the elastic portion 41, and the flexible portion 42 bends toward the door body side surface 23 due to the pressing force of the water at the time of water immersion. 23 adheres closely. Further, 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 due to the pulling force of the entered water, and the flexible portion 42 and the door body side surface 23. Will be in close contact. Thereby, watertightness can be obtained and water can be stopped. Furthermore, the higher the water pressure, the greater the degree of adhesion between the flexible portion 42 and the door body side surface 23, and the water tightness is improved. Therefore, it is not necessary to press the door body side surface 23 against the waterproof rubber or the like in advance unlike the conventional door device having water tightness.

  The water that is about to enter between the frame 13 and the flexible portion 42 is also blocked by the elastic portion 44 and the bottom portion 43, so that the water does not easily enter the inside. As described above, in the first embodiment of the present invention, the water blocking performance is exhibited by a simple configuration in which the elastic member 32 is provided with the flexible portion 42, and water tightness is obtained.

  For example, the watertightness is improved by using or replacing the elastic material 32 shown in FIG. 3 as one embodiment of the elastic material of the present invention as the elastic material of the airtight door device shown in FIG. Can be made.

  In the example shown in FIG. 4, a configuration in which the flexible portion 42 of the elastic material 32 abuts on the door body side surface 23 by closing the door body 12 is shown. However, the flexible portion 42 is in a state where the door body 12 is closed. The structure which adjoins to the door body side surface 23 may be sufficient. In this case, water enters the gap between the door side surface 23 and the flexible portion 42. The intruded water pulls the flexible portion 42 toward the elastic portion 41, and this pulling force and the invading water Due to the pressing force applied to the flexible part 42, the flexible part 42 bends toward the door body side surface 23, the flexible part 42 and the door body side surface 23 come into contact with each other, and is further brought into pressure contact with the door body side surface 23. . Thus, even if the flexible part 42 is close to the door body side surface 23 with the door body 12 closed, the flexible part 42 is caused by the infiltrated water as shown in FIG. The flexible portion 42 and the door body side surface 23 are brought into close contact with each other by being pressed against the door body side surface 23, and water tightness is obtained and water can be stopped.

  Needless to say, the elastic member 32 is not limited to the shape shown in FIG. 3 and may be appropriately modified within the range having the above-described function.

  FIG. 6 is an enlarged 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. 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 elastic material 32 is also provided at the joint 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.

  When the first door body 14 is closed and the second door body 15 is further closed, the elastic material 33 comes into contact with the inner surface of the second door body 15 and is pressed by the second door body 15. Before the second door body 15 is closed, the distal end portion of the flexible portion 42 is located away from the position of the side surface of the second door body 15 when the second door body 15 is closed. When the second door 15 presses the elastic member 33 and the elastic member 33 is deformed, the flexible portion 42 of the elastic member 33 comes into contact with or is close to the side surface of the second door 15 and the elastic member 33 is pressed. 41 and the second door 15 are provided so as to cover the contact portion. With such a configuration, the flexible portion 42 is not caught when the second door body 15 is closed, and the second door even when the flexible portion 42 contacts the side surface of the second door body 15. The force when closing the 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. In addition, 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 pressure due to the water pressure. It is pressed against the side surface of the door body 15. Water is stopped by this pressure contact, and water can be prevented from entering through the gap between the first door body 14 and the second door body 15.

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

  FIG. 7 is a cross-sectional enlarged view showing a third embodiment of the door device of the present invention. In each of the above-described embodiments, examples have been described in which the flexible portions 42 of the elastic members 32 and 33 are in contact with or close to the side surfaces of the door body 12, the first door body 14, and the second door body 15. 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. 7 shows an example of a single-open door device as an example. FIG. 7A shows a state in which the door body 12 is opened, and FIG. 7B 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, a concave portion 31 is provided in a portion of the frame body 13 that faces the four-circumference outer peripheral portion of the door inner surface 22, and the elastic material 32 is fitted into the concave portion 31, and the elastic material 32 is provided. Is provided opposite to the outer peripheral portion of the inner surface 22 of the door body.

  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. It is provided so as to cover. The distal end of the flexible portion 42 faces the outer peripheral portion of the door body 12. The flexible portion 42 has flexibility and is preferably more flexible than the elastic material 32.

  When the door body 12 is closed, the outer peripheral portion of the inner surface 22 of the door body abuts against the elastic portion 41 of the elastic material 32 provided on the frame 13 to press the elastic material 32, and the flexible portion 42 is in the door body. Abuts against the surface 22. As described in the first embodiment, the flexible portion 42 may approach and contact the inner surface 22 of the door body by deformation of the elastic portion 41, or the tip position of the flexible portion 42 may be adjusted in advance. For example, regardless of the deformation of the elastic part 41, the flexible part 42 can be brought close to or further brought into contact with the inner surface 22 of the door body. If the flexible portion 42 is more flexible than the elastic portion 41, the force required to close the door body 12 is hardly changed even when the flexible portion 42 abuts against the inner surface 22 of the door body. 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, the flexible portion 42 is not caught by closing the door body 15.

  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. Due to the pressing force, the flexible portion 42 bends toward the door body inner surface 22 side, and the flexible portion 42 and the door body inner surface 22 are brought into close contact with each other.

Are in close contact. In this way, the flexible portion 42 and the door body inner surface 22 are in close contact with each other to obtain water tightness and prevent water from entering the interior. Furthermore, the higher the water pressure, the greater the degree of adhesion between the flexible portion 42 and the door inner surface 22 and the water tightness is improved. 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. 7, the configuration in which the flexible portion 42 of the elastic member 32 abuts against the inner surface 22 of the door body 12 by closing the door body 12 is shown, but the flexible portion 42 is in a state where the door body 12 is closed. The structure which adjoins to the door body inner surface 22 may be sufficient. Also in this case, the flexible portion 42 comes into contact with the inner surface 22 of the door body due to the pressing force and pulling force of the water that has entered, and further, the flexible portion 42 and the door body side surface 23 are brought into close contact with each other. It can be obtained and stopped.

  In addition, although the single-open door device is illustrated in FIG. 7, it can also be applied 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.
