Description

  The present invention relates to a technique for preventing flooding.

  As background art in this technical field, there is JP-A-10-289345 (Patent Document 1). This publication discloses a technique for preventing an automatic transaction apparatus from being submerged by lifting a waterproof film with a buoyant material when submerged.

Japanese Patent Laid-Open No. 10-289345

However, in the technology described in Patent Document 1, the buoyancy material and the waterproof film are caught by the casing and peripheral members of the automatic transaction apparatus in the process of the rise of the buoyancy material and the waterproof film at the time of flooding. There is a risk of not.
Therefore, the present invention provides a technique for smoothly raising the buoyancy material and the waterproof film during flooding.

  In order to solve the above-described problems, the flooded waterproof device according to the present invention includes a lifting mechanism that lifts the waterproof film separately from the buoyancy acting on the buoyancy material.

Since the lifting mechanism raises the waterproof membrane separately from the buoyancy acting on the buoyancy material, the waterproof membrane can be raised smoothly.
Problems, configurations, and effects other than those described above will become apparent from the following description of embodiments.

  FIG. 1 is an external perspective view of a water intrusion prevention device 20 as Embodiment 1 of the present invention. In the present embodiment, the automatic teller machine 10 (hereinafter also referred to as ATM 10) is adopted as an object (infiltration prevention object) that the inundation prevention apparatus 20 prevents inundation.

  The flood prevention device 20 includes a housing 22, a hole 24, a waterproof film 28, a lid 36, and a resin sheet 37. A waterproof film 28 is laid on the housing 22, and the ATM 10 is placed thereon.

  In the housing 22, a lid portion 36 and a resin sheet 37 are disposed so as to surround the entire circumference of the ATM 10. In the housing 22, a groove 26 is formed below the lid 36 and the resin sheet 37. The groove 26 will be described with reference to FIG. In the normal state, the groove 26 and the resin sheet 37 close the groove 26.

  The lid portion 36 is made of a metal plate member. The lid 36 can be opened and closed in the directions of the arrows S1 and S2 shown. The resin sheet 37 is disposed between the adjacent lid portions 36. The resin sheet 37 is connected to the two adjacent lid portions 36. When two adjacent lids 36 open perpendicularly in the directions of arrows S1 and S2, the resin sheet 37 disposed between the two lids 36 is folded so as not to prevent the lid 36 from opening. . The resin sheet 37 is made of a material that has flexibility and is not easily torn. In this embodiment, an ABS sheet is adopted as the resin sheet 37. The resin sheet 37 may be a rigid rubber sheet.

  The hole 24 is formed at the periphery of the housing 22. At the time of flooding, water penetrates into the housing 22 from the hole 24. A lock mechanism 50 (described later) that maintains the lid 36 in the closed state in the normal state is formed inside the housing 22. The lock mechanism 50 unlocks the lid 36 by water that has entered from the hole 24.

  FIG. 2 is a cross-sectional view showing an AA cross section (see FIG. 1) of the ATM 10 and the flood prevention device 20. A groove portion 26 is formed inside the housing 22 of the inundation prevention device 20. Further, the housing 22 is provided with a lock mechanism 50.

  A portion of the waterproof film 28 other than the portion laid on the housing 22 is accommodated in the groove portion 26. When the waterproof film 28 accommodated in the groove 26 is expanded upward, the waterproof film 28 has a bag shape that covers the ATM 10 from the bottom to the top. A mechanism for raising the waterproof film 28 is accommodated in the groove 26. Details will be described later.

  A cable group 14 for communication and power supply is connected to the ATM 10. The other end of the cable group 14 is connected to an external device or an external power source. The cable group 14 passes through the inside of the housing 22 from the outside, passes through the waterproof film 28, and is connected to the ATM 10. In the waterproof film 28, a packing 16 for suppressing water intrusion from the outside to the inside is disposed in a hole portion through which the cable group 14 passes.

  FIG. 3 is an explanatory diagram showing the internal structure of the housing 22. The housing 22 includes a groove portion 26 and a lock mechanism 50 inside. The groove portion 26 accommodates a waterproof film 28, a buoyancy material 30, an elastic body 32, and a plate-like member 34. As the buoyancy material 30, a member that floats on water, such as wood, polystyrene foam, or polyethylene, or a floating bag in which air is sealed can be used. The buoyancy material 30 is coupled to the periphery of the opening of the waterproof film 28 that forms a bag shape.

  As described above, the waterproof film 28 is laid on the housing 22 and the other part is accommodated in the groove 26 in a folded state. A plate-like member 34 is disposed under the waterproof film 28 folded in the groove 26. An elastic body 32 is disposed under the plate member 34. The upper end of the elastic body 32 is fixed to the plate member 34, and the lower end of the elastic body 32 is fixed to the bottom of the groove 26. The elastic body 32 and the plate-shaped member 34 have a function of raising the waterproof film 28. In the present embodiment, a spring is employed as the elastic body 32. In addition, a damper may be adopted as the elastic body 32. The elastic body 32 is accommodated in the groove portion 26 in a contracted state. At normal times, since the lid portion 36 is in the closed state, the elastic body 32 holds the contracted state.

  The lid portion 36 is rotatably fixed to the housing 22 via a hinge 38. The lid 36 is normally kept closed by the lock mechanism 50. When the lock is released by the lock mechanism 50, the elastic force of the elastic body 32 pushes up the lid portion 36 via the waterproof film 28 and the buoyancy material 30, and the lid portion 36 opens in the direction of the arrow S3 shown in the figure.

  The lock mechanism 50 includes a housing 51, an elastic body 52, a piston 53, a water-soluble member 54, a link mechanism 55, and a lock portion 56. The elastic body 52 is sandwiched between the casing 51 and the piston 53 and maintains a contracted state.

  Normally, the piston 53 is held in a state (contracted state) in which the elastic body 52 is contracted by the solid water-soluble member 54. The water-soluble member 54 is a solid member disposed between the housing 51 and the piston 53 in order to maintain the elastic body 52 in a contracted state in a normal state. As the water-soluble member 54, a water-soluble material such as a potassium compound, a sodium compound, a nitric acid compound, or a water-soluble polymer can be employed. As the potassium compound, potassium hydroxide, potassium iodide, potassium bromide, potassium carbonate, potassium chloride and the like can be employed. As the sodium compound, sodium chloride, sodium nitrate, sodium carbonate and the like can be employed. As the nitrate compound, ammonium nitrate, sodium nitrate, calcium nitrate, potassium nitrate and the like can be employed. As the water-soluble polymer, starch paste, carboxymethyl cellulose and the like can be employed.

  At the time of water immersion, water that has entered the inside of the housing 22 through the hole 24 comes into contact with the water-soluble member 54. The water-soluble member 54 in contact with water dissolves. The piston 53 moves due to the elastic force of the elastic body 52. The elastic force of the elastic body 52 is transmitted to the lock portion 56 via the piston 53 and the link mechanism 55, and the lock portion 56 moves in a direction to release the locked state. The lid 36 that has been unlocked is opened by the elastic force of the elastic body 32.

  FIG. 4 is an explanatory diagram for explaining the hole 24. The holes 24 are formed at equal intervals around the periphery of the housing 22. As shown in the drawing, external water enters the inside of the housing 22 through the hole 24 during water immersion. When the water that has entered the inside of the housing 22 reaches the lock mechanism 50, it dissolves the water-soluble member 54. The lock is released when the water-soluble member 54 melts.

  FIG. 5 is an explanatory view for explaining the state of the inundation preventing device 20 at the time of flooding. As described above, when the water is immersed, the water-soluble member 54 is dissolved in water, so that the lock mechanism 50 unlocks the lid 36. The elastic force of the elastic body 32 is transmitted to the lid portion 36 via the plate member 34, the waterproof film 28 and the buoyancy material 30, and pushes the lid portion 36 open. The elastic force of the elastic body 32 raises the waterproof film 28 and the buoyancy material 30 via the plate-like member 34.

  The opened lid 36 is in a state of leaning against the main body of the ATM 10 and closes the gap between the ATM 10 and the housing 22. The lid portion 36 prevents the rising buoyancy material 30 and the waterproof film 28 from being caught in the gap between the ATM 10 and the housing 22.

  The raised waterproof film 28 forms a bag shape and covers the ATM 10 from the bottom to the top. The waterproof film 28 covers the ATM 10 to prevent the water 99 from entering the ATM 10. When the water surface of the water 99 rises due to water immersion, the buoyancy material 30 raises the waterproof film 28 by buoyancy according to the water surface height. The waterproof film 28 covers the ATM 10 at a position higher than the water surface of the water 99 and prevents the water 99 from entering the ATM 10.

  In the first embodiment, the buoyancy material 30 is coupled to the periphery of the opening of the waterproof film 28 by stitching with a suture thread. In the first embodiment, the waterproof film 28 is stitched to the top of the buoyancy material 30. As a result, the periphery of the opening of the waterproof film 28 is located at a position higher than the water surface of the water 99 at the time of flooding. Therefore, intrusion of the water 99 from the peripheral edge part of the waterproof film 28 is prevented at the time of flooding. In the first embodiment, the waterproof film 28 and the buoyancy material 30 are fixed by stitching, but may be bonded using an adhesive.

  As described above, the flooding prevention device 20 according to the first embodiment raises the waterproof film 28 by the elastic force of the elastic body 32 separately from the buoyancy acting on the buoyancy material 30. Therefore, the infiltration preventing device 20 can raise the waterproof film 28 more quickly than the case where the waterproof film 28 is raised only by the buoyancy of the buoyancy material 30. Further, by raising the waterproof film 28 by the elastic force of the elastic body 32, it is possible to suppress the possibility that the waterproof film 28 is caught on the ATM 10 main body, peripheral members, and the like and the rise is inhibited.

  The flood prevention device 20 has a lid 36. Since the cover part 36 closes the groove part 26 at normal time, it is possible to prevent the user of the ATM 10 from catching his / her foot on the groove part 26 and to ensure safety. At the time of flooding, the lid 36 pushed open by the elastic force of the elastic body 32 closes the gap between the ATM 10 and the housing 22. Therefore, the lid part 36 can reduce the possibility that the rising buoyancy material 30 and the waterproof film 28 will be caught in the gap between the ATM 10 and the casing 22, and raise the buoyancy material 30 and the waterproof film 28 smoothly.

  The water immersion prevention device 20 includes a lock mechanism 50 that releases the lock when the water is immersed. Since the lock mechanism 50 locks the lid portion 36 so as not to be opened in a normal state, it is possible to avoid an erroneous operation in which the user or a maintenance worker accidentally releases the lock. In addition, since the lock mechanism 50 quickly releases the lock at the time of flooding, the buoyancy material 30 and the waterproof film 28 can be quickly lifted to prevent the ATM 10 from being flooded.

  The inundation prevention device 20 raises the buoyancy material 30 and the waterproof film 28 by the elastic body 32. Therefore, the buoyancy material 30 and the waterproof film 28 can be raised with a relatively simple structure as compared with the case of using a damper using gas pressure or air pressure.

  Since the inundation preventing device 20 is configured as the housing 22, it can be easily installed as compared with a case where a groove or a lock mechanism is directly configured on the ground on which the ATM 10 is installed. The ATM 10 provided with the inundation preventing device 20 can prevent inundation promptly by the buoyancy material 30 and the waterproof film 28 that have risen smoothly during the inundation.

  In this example, the inundation prevention device 20 is installed in the automatic transaction apparatus. Therefore, money stored in the automatic transaction apparatus can be protected from flooding.

  As a correspondence relationship with the claims, the plate member 34 and the elastic body 32 correspond to the ascending mechanism described in the claims, and the groove 26 corresponds to the accommodating portion described in the claims.

  A second embodiment of the present invention will be described. Since the difference between the first embodiment and the second embodiment is only the configuration of the lock mechanism, in this description, the lock mechanism 60 in the second embodiment will be described, and description of other configurations will be omitted. FIG. 6 is an explanatory diagram illustrating a configuration of the lock mechanism 60 according to the second embodiment. The lock mechanism 60 includes a housing 61, a buoyancy material 62, a link mechanism 65, and a lock portion 66. A buoyancy material 62 is disposed in the housing 61. One end of a link mechanism 65 is connected to the buoyancy material 62.

  FIG. 7 is an explanatory view for explaining the state of the inundation preventing device 20 at the time of flooding. When water 99 intrudes from the hole 24 at the time of water immersion and the water surface reaches a predetermined height or more, water enters the housing 61. When water enters the housing 61, the buoyancy material 62 rises due to buoyancy. The ascending buoyancy material 62 moves the lock portion 66 by driving the link mechanism 65. The lock mechanism 60 releases the lock to the lid portion 36 by moving the lock portion 66. Since the subsequent operations of the lid portion 36, the elastic body 32, the plate-like member 34, the waterproof film 28, and the buoyancy material 30 are the same as those in the first embodiment, description thereof is omitted.

  As described above, the inundation preventing apparatus 20 according to the second embodiment uses the buoyancy material 62 to detect water during flooding. Therefore, it is not necessary to prepare a water-soluble member as in the first embodiment. Further, it is possible to avoid a malfunction such that the water-soluble member is melted by the humidity in the air and the lock is released.

  A third embodiment of the present invention will be described. Since the difference between the first embodiment and the third embodiment is only the configuration of the lock mechanism, in this description, the lock mechanism 70 in the third embodiment will be described, and description of the other configurations will be omitted.

  FIG. 8 is an explanatory diagram illustrating a configuration of the lock mechanism 70 according to the third embodiment. The lock mechanism 70 includes a housing 71, an elastic body 72, a piston 73, a buoyancy material 74, a link mechanism 75, and a lock portion 76. The elastic body 72 is compressed by one end of the housing 71 and the piston 73 and maintains a contracted state. The piston 53 is fixed by a buoyancy material 74 in a state where the elastic body 52 is contracted (contracted state). The tip of the buoyancy material 74 forms a wedge shape. The tip of the buoyancy material 74 penetrates from the outside to the inside of the housing 71 and fixes the piston 53.

  FIG. 9 is an explanatory view for explaining the state of the inundation preventing device 20 during inundation. When the water 99 enters from the hole 24 during the flooding and the water surface reaches a predetermined height or more, the buoyancy material 74 rises by buoyancy. When the buoyancy material 74 rises, the fixed piston 73 is moved by the elastic force of the elastic body 52. By the movement of the piston 73, the link mechanism 75 and the lock portion 76 operate, and the lock of the lid portion 36 is released. Since the subsequent operations of the lid portion 36, the elastic body 32, the plate-like member 34, the waterproof film 28, and the buoyancy material 30 are the same as those in the first embodiment, description thereof will be omitted.

  As described above, the inundation preventing apparatus 20 according to the third embodiment uses the buoyancy material 74 to detect water during flooding. Therefore, it is not necessary to prepare the water-soluble member 54 as in the first embodiment. Further, it is possible to avoid a malfunction such that the water-soluble member 54 is melted by the humidity in the air and the lock is released.

  Embodiment 4 of the present invention will be described. FIG. 10 is an explanatory diagram for explaining the buoyancy material 90 and the lid portion 96 in the fourth embodiment. The difference between the first embodiment and the fourth embodiment is the configuration of the lid portion 96 that closes the groove portion 26 and the buoyancy material 90 that floats the waterproof film 28. In this description, the lock mechanism 80 employs either the lock mechanism 50 in the first embodiment, the lock mechanism 60 in the second embodiment, or the lock mechanism 70 in the third embodiment.

  Unlike the lid portion 36 and the buoyancy material 30 in the first embodiment, the lid portion 96 and the buoyancy material 90 are joined. Further, the flood prevention device 20 according to the fourth embodiment does not include the hinge 38 (see FIG. 3). The lid portion 96 is fixed to the groove portion 26 by a lock mechanism 80.

  FIG. 11 is an explanatory diagram for explaining the state of the inundation preventing device 20 during inundation. When the water 99 enters from the hole 24 at the time of flooding and the water surface reaches a predetermined height or more, the lock mechanism 80 unlocks the lid 96. When the lock is released, the lid portion 96 and the buoyancy material 90 rise while maintaining the joined state. As the buoyancy material 90 rises, the waterproof film 28 fixed to the buoyancy material 90 also rises. The raised waterproof film 28 forms a bag shape and covers the ATM 10 from the bottom to the top. The waterproof film 28 covers the ATM 10 to prevent the water 99 from reaching the ATM 10. When the water surface of the water 99 rises due to water immersion, the buoyancy material 90 raises the waterproof film 28 by buoyancy. The waterproof film 28 covers the ATM 10 at a position higher than the water surface of the water 99 and prevents the water 99 from entering the ATM 10.

  As described above, the water intrusion prevention device 20 according to the fourth embodiment does not require a hinge for fixing the lid portion 96 and the housing 22 and can simplify the structure. Moreover, the operation of joining the lid portion 96 and the housing 22 can be avoided at the time of manufacturing the flood prevention device 20.

Even if it does in this way, the effect similar to the said Example can be acquired.

-Modification 4:
In the above embodiment, the waterproof film 28 has a bag shape that covers the ATM 10 from the bottom to the top. However, other shapes may be adopted as the shape of the waterproof film 28.

The other end of the two open ends of the waterproof film 28 is coupled to the buoyancy material 30. That is, the ATM 10 is covered from the bottom to the top by the cylindrical waterproof film 28 and the side surface of the casing 22 surrounded by the waterproof film 28 (the side surface of the housing 22 facing the bottom surface of the ATM 10). Even if it does in this way, the effect similar to the said Example can be acquired.
