Description

The present invention relates to the technical field of water stop devices installed at entrances and exits of buildings such as buildings.

In general, water that overflows due to heavy rain may infiltrate (flood) into buildings (indoors, indoors) through the entrances and exits of buildings and other structures. Attempts have been made to provide a device (waterproofing device). Among such water stop devices, when there is no risk of flooding, the water stop body (water stop plate, waterproof body) is stored in a storage location such as underground (under the floor) so as not to impede passage at the entrance. There is a known device in which, in an emergency when there is a risk of flooding due to heavy rain, etc., the water stop body in the storage position is moved upward and placed in the water stop position to shut off the water. (For example, see Patent Document 1.).
However, in this device, the water stop body folded in a zigzag shape is lifted up by the biasing force of the projectile to take a straight water stop position; Even if it does, the zigzag condition cannot be completely wiped out, and as a result, a gap inevitably forms between the water stopper and the receiving member that receives the waterstop, preventing water from entering. The problem is that it is difficult.
Therefore, a structure in which a plate-shaped water stop body is configured to be vertically movable from a low storage position to a water stop position where water is stopped has been proposed (for example, see Patent Document 2).

Japanese Patent Application Publication No. 2002-227453 Patent No. 2527333

However, if the plate-shaped water stopper is simply moved upward from the storage position to the water stop position, there will inevitably be a gap between the water stopper in the water stop position and the receiving member that receives it, which causes water to seep in. become. Therefore, this product is equipped with a pressing means configured to press the water stop body that has moved upward to the water stop position in the horizontal direction and maintain this pressed state. Since it is oriented horizontally rather than in the direction in which the water stops, it is not possible to utilize the upward force of the water stopper, which not only requires a separate member, but also requires pushing in the horizontal direction, making it difficult to operate. There are problems such as inferiority, and these are the problems to be solved by the present invention.

The present invention was created with the aim of solving these problems in view of the above-mentioned circumstances. A water stop body that can be moved up and down between a water stop position and a water stop position, a displacement force applying means that applies a displacement force for displacing the water stop body from a storage position to a water stop position, and a water stop body that stops the water stop body from a storage position. In a water stop device configured with a guide means for guiding toward a water position and a receiving means for receiving a water stop body displaced to a water stop position and stopping water, the displacement force applying means is provided in the storage body. In the process of displacing the water stop body from the storage position to the water stop position, the guide means is displaced from a separated position where the water stop body is separated from the receiving means to an abutment position where it abuts on the receiving means. This water stop device is characterized by being configured to guide the water at an incline.
The invention according to claim 2 is the water stop device according to claim 1, wherein the guide means is an inclined rod disposed in the storage body.
The invention according to claim 3 is characterized in that the water stop body is provided with a detachable locking means for holding the water stop body in the storage position against the displacement force of the displacement force applying means. A water stop device according to claim 1 or 2 .
The invention according to claim 4 is the water stop device according to any one of claims 1 to 3 , characterized in that the water stop body is set such that the protrusion height corresponds to a case where the submergence depth is shallow. .

According to the invention of claim 1, when the water stop body is displaced from the storage position to the water stop position in response to the displacement force of the displacement force applying means while being guided by the guide means, the water stop body is displaced from the water stop position by the receiving means. As a result, the water stop body that has moved up to the water stop position comes into contact with the reception means, and the water stop body is moved upward to the water stop position. The upward motion is automatically guided by the guiding means, so there is no need to provide a separate pressing means and a separate operation for pressing, and the structure is simple and easy to operate. It can be done.
Moreover, since the displacement force applying means can be constituted by a bullet disposed in the storage body, the structure can be further simplified.
According to the second aspect of the present invention, the guide means can be constituted by an inclined rod disposed within the storage body, so that the structure can be further simplified.
According to the invention of claim 3 , the water stop body is held in the storage position by the locking means, and can be stably held in the storage position in normal times without flooding, but when flooding is anticipated. In an emergency such as when the water is stopped, by releasing the lock, the receiver member moves to the water stop position where the water stop is automatically performed, which improves the reliability of water stop.
According to the invention of claim 4 , the water stop body can be provided as a simple type whose protrusion height corresponds to a case where the submergence depth is shallow, so that the water stop body has high versatility.

Embodiments of the present invention will be described below based on the drawings. In the drawing, reference numeral 1 denotes a water stop device, and the water stop device 1 is installed at an entrance E of a building such as a building.Fixed mirror plates 2 are installed on both left and right sides of the entrance E. is provided to serve as a door pocket, and a so-called sliding door type door body 3, which is disposed (located) on the indoor side of the mirror plate 2 and moves from side to side to open and close the doorway E, is provided so as to open from both sides to the left and right. It is being In this embodiment, the door body 3 is of an automatic opening/closing type.
In this case, the structure for automatically opening and closing the door body 3 is not directly related to the implementation of the present invention, and a general-purpose structure is adopted, so the specific structure is omitted, but the present invention In implementing this, the door body is not limited to an automatic opening/closing type, but may be a manual opening/closing type, and is not limited to a sliding door type, but may be a hinged door that swings back and forth to open and close. It goes without saying that even if the present invention is based on this method, it can be implemented in the same manner as in this embodiment.

The water stop device 1 is a simple type that is configured to cope with submergence depths at low water levels, such as a water stop height of about 5 cm or 10 cm. can be set as appropriate if necessary.
The water stop device 1 is installed on the outdoor side (outdoor side) of the opening/closing area of the door body 3, at a foot sliding portion Z between the left and right head panels 2. A groove is formed in the shape of a concave groove from the surface F, and a case body (corresponding to the "storage body" of the present invention) 4 having an open top surface is fitted into the groove. The body 4 forms a storage space (storage space) for the water stop body 5.

The water stop body 5 has a box-like hollow shape including a bottom surface 5a, front and rear indoor and outdoor side surfaces 5b and 5c, a top surface 5d, and left and right side surfaces 5e. (width) and the length between the left and right side parts 5e are shorter (narrower) than the length of the case body 4 in the indoor and outdoor directions and the length in the left and right directions. 4 and is set so that it can move vertically relative to the case body 4 without contacting the case body 4 (non-contact).
Incidentally, the upper surface portion 5d of the water stop body 5 corresponds to a grating (groove cover), and is designed to be thick so as not to deform even when moved by people, carts, etc.

On the other hand, a spacer 4b is provided on the bottom part 4a of the case body 4 so as to be located on both indoor and outdoor sides, and the water stop body 5 is fitted into the case body 4 with the bottom part 5a in contact with the spacer 4b. As a result, the upper surface portion 5d is located at a storage position flush with the floor surface F.
Furthermore, a mounting seat 4c is provided on the bottom surface 4a of the case body 4, and is located midway between indoor and outdoor directions. The lower end of the rod 6 is supported (fixed), and the rod 6 is inclined so that the upper end thereof is located closer to the indoor side. A regulating body 6a is provided at the tip of the rod 6 to abut against the guide receiver top plate portion 5h and to regulate further upward movement of the water stop body 5.

On the other hand, a large-diameter through hole 5f into which the rod 6 is loosely fitted is formed in the bottom portion 5a of the water stopper 5, and a guide receiver 5g having a hat-shaped cross section is provided so as to straddle the through hole 5f. installed. A small-diameter through hole 5i through which the rod 6 passes is formed in the top plate portion 5h of the guide receiver 5g.
Between the case body 4 and the water stop body 5, specifically, between the mounting seat 4c provided on the bottom surface 4a of the case body and the top plate portion 5h of the guide receiver 5g provided on the water stop body 5, While housed in the case body 4, the coil-shaped (cylindrical) bullet (corresponding to the "displacement force applying means" of the present invention) 7 is loosely fitted into the through hole 5f provided in the bottom surface portion 5a of the water stopper body. The rod 6 is provided in a loosely-fitted manner to penetrate the rod 6, but when the bomb 7 is in the storage position where the bottom surface 5a of the water stopper body is in contact with the spacer 4b, the rod 6 is compressed (elastic pressure). ), and is set to exert an urging force (displacement force) for forcibly moving the water stop body 5 toward the water stop position where it protrudes from the case body 4 and stops water, as will be described later.

Further, the water stop body 5 is provided with a locking means for locking and holding the water stop body 5 in the storage position against the biasing force of the ammunition 7. It is configured to include a convex portion 8 provided on the side surface portion 5c and a latch tool 9 provided on the outdoor side surface portion 5b.
A plurality of convex portions 8 are provided at intervals in the left-right direction so as to protrude outward with respect to the indoor side surface 5c, and when the water stopper 5 is in the storage position, the convex portions 8 of the case body 4 are It is set to be removably inserted into and locked into a locking hole 4e provided on the indoor side surface 4f.

On the other hand, the latch tool 9 includes a case 9a provided on the outdoor side surface 5b of the water stopper 5, a movable body 9b provided so as to be movable in the left and right directions while being accommodated in the case body 9a, and a The latch 9c changes its shape from a locked position protruding from the outdoor side surface 5c to a released position recessed into the water stop body 5 side in conjunction with the movement, and a movable body 9b so that the latch 9c returns from the released position to the locked position. In this embodiment, the return bullet mechanism 9d of the movable body 9b is linked to the pulling operation of the wire (rope body) 9e connected to the movable body 9b. The latch 9c is configured to move downward from the locked position to the released position by movement against the force, but a general-purpose latch tool 9 is used, and its specific configuration is not explained below. The explanation of is omitted.
When the wire 9e is not pulled, the latch 9c is set to be removably inserted into a locking hole 4g formed in the outdoor side surface 4d of the case body 4.
In this embodiment, the wire 9e is disposed within the water stopper 5 so as to reach one side in the left-right direction, and is connected to the actuator 10 provided on the upper surface 5d. The actuating body 10 is integrally connected to a support shaft 10a that is rotatably provided with the upper end edge visible from above with respect to the upper surface portion 5d. Then, a tool (for example, a flathead screwdriver) corresponding to the tool locking groove (for example, a flathead groove) formed on the upper end edge of the support shaft 10a is inserted and locked and rotated, thereby locking the wire 9e and the latch 9c. It is possible to perform a pull operation to change the shape in the direction of release.
In addition, since the tip of the actuating body 10 is locked to the case body 4, the balance of the water stop body 5 is affected by the fact that the convex part 8 and the latch 9c are locked to the case body 4. Not only can the water stopper 5 be properly locked to the case body 4, but also the water stopper 5 can be smoothly moved upward when the latch 9 is released.

Next, the operation of the water stopper 5 will be explained with reference to FIGS. 5 and 6. In normal times, the water stop body 5 is located in a storage position where the bottom surface 5a is in contact with a spacer 4b provided on the case body bottom surface 4a. are set at intermediate positions spaced apart from the inner and outer surfaces 4d and 4f of the case body, and in this state, the convex portion 8 is locked in the locking hole 4e formed in the inner and outer side surface portions 4f of the case body, and , the latch 9c is locked in a locking hole 4g formed in the case body outdoor side surface 4d, so that the water stop body 5 can be stored in the case body 4 in a state where it resists the biasing force of the ammunition 7. held in position.

In this holding state, when the operating body support shaft 10a is rotated and the wire 9e is pulled as described above, the latch 9c swings downward in conjunction with this and swings in the direction of coming out of the locking hole 4g. As a result, the water stop body 5 receives the urging force of the bomb 7, and the outdoor side surface portion 5b moves upward, and the bottom surface portion 5a tilts and moves in the direction in which it comes into contact with the case body outdoor side surface portion 4d. When the convex portion 8 comes out of the locking hole 4e, the latch 9c also comes out of the locking hole 4g, and the locking by the locking means is released.

When the locking by the locking means is released in this way, the water stopper 5 moves upward under the urging force of the projectile 7, but in this case, the water stopper 5 is guided by the rod 6 at an angle. As a result, the water stopper 5 moves upward while approaching the inner side surface 4f of the case body, and the water stopper 5 moves upward to a position where the guide receiver top plate 5h abuts against the regulating body 6a and further upward movement is regulated. However, the position where the upward motion is restricted is the water stop position where the water stop body 5 protrudes from the case body 4 because it exhibits the water stop function. The lower end of the case body 5c comes into contact with the case body indoor side surface 4f, and the left and right sides of the indoor side surface 5c also come into contact with the vertical pieces 11 on the frame side formed at the lower parts of the left and right sides of the entrance/exit area. This prevents water from entering from the outdoor side.
When the water stop body 5 moves upward to the water stop position in this way, in this embodiment, the case body interior side surface portion 4f and the vertical piece portion 11 that the water stop body 5 comes into contact with are the "receiving member" of the present invention. This results in a water-stopping function. Of course, the receiving member is not limited to this, and for example, the vertical piece 11 can be used as a door stop for the door body 3 when the door body 3 is opened.Furthermore, such a water stop body 5 In the process of upward movement, the convex portion 8 moves upward in contact with the case body indoor side surface 4f, so the water stop body indoor side surface 5c moves upward while slidingly contacting the case body indoor side surface 4f. Upward movement while encountering resistance is avoided, and smooth upward movement of the water stopper 5 is achieved.

In this embodiment configured as described above, the water stop body 5 is housed in the case body 4 at all times when there is no risk of flooding, and does not obstruct passage through the entrance/exit E. However, if it is determined that there is a risk of flooding, the administrator rotates the operating body support shaft 10a and pulls the wire 9e, causing the water stopper 5 housed in the case body 4 to become resilient. Under the urging force of the machine 7, it protrudes from the case body 4 and moves upward to the water stop position where it stops water.At this time, the water stop body 5 moves upward under the guidance of the rod body 6. The rod 6 is brought into contact with the indoor side surface 4f from a distance position where the water stopper 5 is separated from the indoor side surface 4f of the case body 4 in the process of displacing the water stopper 5 from the storage position to the water stop position. As a result, although the water stop body 5 automatically moves upward from the storage position to the water stop position under the urging force of the bomb 7, the upward movement In the process of doing so, the water stopper 5 is guided from a position where it is separated from the inner side surface portion 4f of the case body and the vertical piece portion 11 on the body side, which serve as receiving members, to be inclined and guided so as to come into contact with these in an elastic manner. As a result, there is no need to provide a separate pressing means, and the structure is simple and easy to operate.

Furthermore, in this case, what guides the water stopper 5 at an angle is the inclined rod 6 disposed inside the storage case 4, and the means for applying a displacement force for moving the water stopper 5 upward is the storage case. 4, these members can be arranged compactly within the storage case 4, and the structure of the water stop device can be simplified.
Moreover, in this case, since the ammunition 7 has a structure in which the rod 6 is fitted through the rod 6, further compactness can be achieved.
Incidentally, as a configuration for guiding the water stop body 5 in an inclined manner, for example, convex guide pieces are provided on the left and right side surfaces 5e of the water stop body 5, and the guide pieces are guided by inclined guides provided on both left and right side surfaces of the case body 4. Also, the means for applying a displacement force for upwardly displacing the water stop body 5 is not limited to the bomb 7, but a device having a displacement force such as a damper can be adopted. Needless to say.

Furthermore, in this case, the water stopper 5 located in the storage position is provided with a removable locking means to hold the water stopper 5 in the storage position against the biasing force of the ammunition 7. The water body 5 is prevented from moving up to the water stop position inadvertently, and the locking means is provided on both the indoor and outdoor sides by a convex portion 8 on the indoor side and a latch device 9 on the outdoor side. This ensures that the water stopper 5 is held in the stored position, while the water stopper 5 can be reliably moved upward by releasing the latch 9 on the indoor side. It turns out.
In this case, the water stop body 5 is set as a simple type whose protrusion height corresponds to the case where the depth of flooding is shallow as described above, so the water stop body 5 itself is lightweight and has an upward movement amount. Since the distance may be as small as several centimeters, a simple member such as the bomb 7 can be used to apply the force to displace the water stopper 5.

It should be noted that the present invention is of course not limited to the above-mentioned embodiment, and the upward movement of the water stop body 5 is changed from the above-described embodiment to a manual type in which the support shaft 10a is rotated. However, this can be made automatic. In this case, the actuating body 10 may be linked to an actuating arm 12a provided on an actuating means 12 operated by an electromagnetic solenoid, for example, so that it can be remotely controlled from a control room or the like, and further, water intrusion detection may be performed. The actuating means 12 may be automatically actuated based on (for example, rainfall detection).
In order to further improve the water stop function of the water stop body 5 that has moved upward, a plate with rubber elasticity is provided at the part of the water stop body 5 that comes into contact with the case body 4 etc. to stop water, as shown in FIG. 9(A). Alternatively, as shown in FIG. 9(B), a sealing material 14 may be provided that presses against the inner surface of the opening vertical frame 13. In this case, the vertical frame 13 is often a component of the receiving member of the present invention.
Furthermore, the water stop device according to the present invention is not limited to the entrances and exits of buildings and other structures, but can also be applied to mounds that are one step higher than the ground, such as entrances and exits from the ground installed in subways, underground passages, etc. It can also be implemented by providing it in a raised area.

INDUSTRIAL APPLICATION This invention can be utilized as a water stop device provided in the entrance and exit of buildings, such as a building.
