[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is mainly a waterproof door device for preventing water from entering an entrance of a building, parking lot facility, etc., and particularly, a waterproof door device provided with a mechanism for closing a gap formed between the waterproof door and the door contact frame. The present invention relates to a water door device.

[0002]

[Prior art]

 A waterproof door is normally laid horizontally in the pit provided on the floor of the doorway to close the opening of the pit, and when the drive mechanism is activated in an emergency, the door such as a link hinge is opened and closed. The waterproof door device installed so as to block the entrance and exit by pivoting up and down from the hinge mechanism as a starting point to move in the direction of abutting against the door contact frame of the entrance and exit, is disclosed in Japanese Utility Model Publication No. 56-27358. It is widely known, for example, in Japanese Patent Publication No. Sho 59-144033, that the conventional waterproof doors of this type are all provided when the waterproof door is laid down and pivoted between the door and the entrance. There is always a gap that can be moved in the direction of this frame. For this reason, an auxiliary door that can be pivotally raised in the same direction as the pivoting direction of the waterproof door from between the doors of the doorway to the waterproof door is installed so that it always remains in a lying state following the waterproof door. However, even if this auxiliary door is provided, it is not possible to fill only the air gap formed between the door frame and the base edge of the waterproof door. , There is a risk that foreign matter may enter through this gap and the waterproof door may cause a drive failure, or a child may be injured in the gap.

[0003]

[Problems to be solved by the device]

 The problem to be solved by the present invention is to solve the above-mentioned problems and completely close the gap formed between the base edge of the waterproof door and the door contact frame to prevent the entry of foreign matter from this gap. Another object of the present invention is to provide a waterproof door device in which a drive failure of the waterproof door due to intrusion of foreign matter is eliminated and a child is not injured in a void.

[0004]

[Means for Solving the Problems] A waterproof door device according to the present invention, which has solved the above-mentioned problems, has a state in which a waterproof door is always laid down horizontally in a pit provided on a floor surface of an entrance / exit. Although the opening of the pit is blocked, when the drive mechanism is operated in an emergency, it is installed so as to move up and down while pivotally standing up and move to the direction in which it contacts the door frame of the doorway. In a waterproof door device, a blindfold plate capable of standing upright in a direction orthogonal to the pivoting direction of the waterproof door is always provided in a space formed between the door contact frame and the laid down waterproof door. The feature is that it is installed in a state of being prone to fall below the waterproof door.

[0005]

[Action]

 In such a waterproof door device, since the gap formed between the base edge of the waterproof door and the door contact frame is closed by the blindfold plate when the waterproof door is lying down normally, It is possible to completely close the gap formed between the base edge of the door and the door frame, which causes foreign matter to enter through this gap, which may cause a drive failure in the waterproof door, or children to be injured in the gap. The fear of doing things is eliminated. If there is a risk of water inundation in buildings or parking facilities, the waterproof door can be pivotally raised together with the blindfold plate so that the waterproof door will not be obstructed by the blindfold plate. While moving to the side, it draws a trail that pivots upright and abuts on the door frame to waterproof the entrance.

[0006]

【Example】

 Next, the present invention will be described in detail based on the illustrated embodiment. Reference numeral 1 denotes a waterproof door that normally closes an opening of a pit 5 formed on the front floor surface of the doorway in a horizontally lying state. The waterproof door 1 is provided with a drive mechanism (not shown) in an emergency. When it is driven, it shifts to the direction in which it comes into contact with the door frame 4 at the entrance and exit while being pivotally erected from the hinge mechanism 2 that opens and closes the door such as the link hinge that connects the waterproof door 1 to the pit 5. Then, it can be undulated by closing the entrance. 3 is a blindfold plate which is provided in a space formed between the door contact frame 4 and the waterproof door 1 which is laid down, and which is normally in a laid-down state substantially horizontal to the waterproof door 1. The blindfold plate 3 is pivotally attached at its base end to a frame 6 provided in a pit 5 so that it can pivot and stand in a direction orthogonal to the pivot direction of the waterproof door 1.

Reference numeral 7 denotes an inclined base stretched on the lower surface of the base edge of the waterproof door 1, and the inclined base 7 contacts an inclined contact surface 8 formed on one side edge of the blind plate 3. The tilt table 7 pushes up the contact surface 8 when the waterproof door 1 is pivotally erected, so that the blindfold plate 3 is pivotally erected at the same time. Reference numeral 9 is a spring for urging the blindfold plate 3 in the closing direction. The blindfold plate 3 is urged by the spring 9 in a direction in which the blindfold plate 3 is always laid down. The vertical surface 8 is erected along the inclined table 7, the upper surface 10 and the side edge 11 of the waterproof door 1. Reference numeral 12 is a seal member attached to the surface of the door contact frame 4 and abutting against the waterproof door 1, and 13 is always provided between the door contact frame 4 at the entrance and the exit and between the blindfold plates 3 on both sides. Is an auxiliary door provided in a state of being laid down substantially horizontally, and the auxiliary door 13 is capable of pivoting and standing in the same direction as the pivoting direction of the waterproof door 1.

With this structure, when the waterproof door 1 is lying down, the gap formed between the base edge of the waterproof door 1 and the door contact frame 4 is closed by the blindfold plate 3. Since the foreign matter enters the pit 5 through the gap, the waterproof door will not drive and the child will not be injured in the gap. In addition, if there is a risk of water inundation in buildings or parking lot facilities, the drive mechanism is activated, and the waterproof door 1 is pivotally erected by the hinge mechanism 2 that opens and closes the door, such as the link hinge, while standing up and down at the entrance and exit. In order to draw a locus that shifts in the direction in which it contacts the door contact frame 4, the blindfold plate 3 whose contact surface 8 is in contact with the inclined base 7 of the waterproof door 1 also resists the elastic force of the spring 9. The waterproof door 1 is pushed up and is pivotally erected in a direction orthogonal to the pivoting direction of the waterproof door 1, and as the pivoting movement of the waterproof door 1 progresses, the contact surface 8 of the blindfold plate 3 is now the upper surface of the waterproof door 1. When the waterproof door 1 is pushed up and is in contact with the seal member 12 of the door contact frame 4, the waterproof door 1 comes into contact with the side edge of the waterproof door 1 to maintain the standing state. To be done.

When the risk of water intrusion from the entrance / exit disappears, the drive mechanism is reversely operated to lay down the waterproof door 1 horizontally with the floor, and the waterproof door 1 is held at the side edge of the waterproof door 1. The blindfold plate 3 is lowered by the waterproof door 1 which is biased by the spring 9 and falls down, and when the waterproof door 1 is laid down horizontally, the contact surface 8 of the blindfold plate 3 is the slanted base 7 of the waterproof door 1. Since it is laid down while being held in contact with, the gap between the waterproof door 1 and the door contact frame 4 is closed.

[0010]

[Effect of device]

 As is apparent from the above description, the present invention keeps the waterproof door horizontally in a pit provided on the floor of the entrance and exit, and closes the opening of the pit. In the waterproof door device installed so as to pivotally stand up and move toward the door contact frame of the entrance and exit to block the entrance and exit, In the space formed between the waterproof door and the blind door, a blindfold plate that can be pivoted upright in the direction orthogonal to the pivot direction of the waterproof door is always provided so as to be in a lying state following the waterproof door. In addition to completely closing the gap formed between the base edge of the waterproof door and the base end of the door frame, it is possible to eliminate the drive obstacle of the waterproof door caused by the entry of foreign matter from this gap. The direction in which the child is not injured in the void, and especially the blindfold is always prone. If the contact surface that is biased by a spring and is formed on the waterproof door side is in contact with the inclined table provided at the base edge of the waterproof door, the blindfold plate will open and close in conjunction with the waterproof door. Since it does not need to incorporate a new drive mechanism into the pivot of the blindfold plate, it can be provided at a particularly low cost, and because the blindfold plate is spring-biased, it is not affected by the vibration caused by the passage of the vehicle. This blindfold plate does not flutter and generate noise, and since the blindfold plate is not opened and closed freely, children will not be mischievous and it will be more safe. Therefore, the present invention has a great practical value as a waterproof door device which solves the conventional problems.
