Description

  The present invention relates to a undulating waterproof door device that is installed to prevent inundation at the entrance or road of a building, an underground parking lot, or the like during a flood.

  In the event of floods such as heavy rains, buildings that are expected to be inundated, underground doors and roads, and roads are provided with waterproof doors to prevent inundation. The slide type and the undulation type are used.

  Of these, the undulating type is often installed in places where aesthetic maintenance is required, such as building entrances, so the undulating of the waterproof door can be done manually or using an air cylinder or oil cylinder, or a gear device Etc. are used.

  However, as shown in the drawings described in Patent Documents 1 and 2, in the conventional undulating waterproof door device, the waterproof door is pivoted upright so that a slight gap exists between the doorway and the waterproof door in the overturned state. A foreign object may enter the storage box through this gap and hinder the operation of the waterproof door, or a passerby may catch the foot, or a child may get injured by putting a hand in the gap. There was a fear.

The drive device for hoisting is installed at the center of the hoisting door, and the waterproof door is hoisted around the hinge and the hoisting door is pressed against the door to maintain watertightness. As compared with the portion, the end portion of the door body is weak, and a force is applied to the hinge portion due to the structure, so that there is a problem that the water tightness of the lower portion of the waterproof door body is weakened when it is erected.
JP-A-9-170382 JP-A-11-294026

  Therefore, the present invention reduces the gap formed between the waterproof door and the entrance and exit to prevent entry of foreign objects and accidents when lying down, and watertightness of the end of the waterproof door on the hinge side when the waterproof door stands. It is an object of the present invention to provide a undulating waterproof door device that raises the height.

  The present invention has been made to solve the above-mentioned problems, and the first invention includes an attachment member provided on the waterproof door and an inclined portion that engages at the entrance / exit side of the fixed base for hinges provided on the storage box when standing up. The undulation is characterized in that a mounting member provided on the waterproof door and the hinge fixing base are connected by a link, and a support member is provided to support the front and rear portions of the waterproof door when the waterproof door is laid down. Type waterproof door device.

  According to a second aspect of the present invention, there is provided a undulating waterproof door device according to the first aspect, wherein a roller for supporting the waterproof door is provided on a support member provided at a front portion of the waterproof door.

  According to the first aspect of the invention described above, when the mounting member provided on the waterproof door and the fixed base for hinges provided in the storage box are connected via the link, and the waterproof door is laid down, Since it is configured to rotate while being moved backward away from the contact side and the clearance between the waterproof door and the entrance is reduced as much as possible when lying down, the problem of the gap between the waterproof door and the entrance and exit is solved, and the waterproof door Since the mounting member provided on the waterproof door and the inclined part provided on the fixed base for hinges provided in the storage box engage with each other, Therefore, there is an effect of increasing the water tightness of the hinge side end of the waterproof door.

  Further, according to the second invention, when the waterproof door is raised and lowered, the roller can be smoothly moved in the horizontal direction, and the noise generated by the waterproof door and the storage box during driving can be reduced.

  FIG. 1 is a partially cut-away side view of a waterproof door in a undulating waterproof door device according to an embodiment of the present invention when lying down, FIG. 2 is a plan view thereof, and FIG. 3 is a partially cut-away side view when standing up. A waterproof door, 2 is a storage box, and 3 is a door stop. Reference numeral 4 denotes an attachment member provided on the waterproof door 1, and an inclined portion 5 is provided on the entrance / exit side, which has a wedge shape. 6 is a hinge fixing base provided with an inclined portion 7 on the entrance / exit side provided in the storage box 2, 8 is a link pivotally attached to both hinge portions 4 and 6, and 9 is a stopper provided on the hinge fixing base 6. 10 ′ is a nylon roller provided on the support member 10, 11 is a receiving portion of the roller provided on the lower surface of the waterproof door 1, and 12 is a support member for the waterproof door 1 provided with a rubber plate 12 ′ on the upper side. , 13 is a U-shaped rubber packing provided per door, 14 and 15 are front edge members and rear edge members provided at both ends of the waterproof door, and the front edge member 14 is the rubber packing 13 described above. The rear edge member 15 is formed so as not to come into contact, and is configured to ride on the rear edge of the storage box 2 when lying down. Reference numeral 16 denotes a stopper provided at the storage box 2 when the waterproof door is erected. In addition, the drive device for undulation uses a well-known thing, and is abbreviate | omitted here and is not shown in figure.

  4-7 is operation | movement explanatory drawing which shows the behavior of the hinge part of the raising / lowering waterproof door apparatus of the said Example 1 from the lying down state to an upright state.

  Hereinafter, operations from the lying state to the standing state of the undulating waterproof door device according to the first embodiment will be sequentially described with reference to FIGS.

  First, in the operation from the lying down state to the standing up state, the waterproof door 1 is lifted from the lying down state shown in FIG. 4 as shown in FIG. 5 until it is locked by the stopper 9 in the direction away from the door stop 3 in the drawing. Move to the right.

  For this reason, the prevention door 1 can stand up without bringing the front edge member 14 into contact with the storage box 2.

  Next, as shown in FIG. 6, the waterproof door 1 rotates around the pivot 17 of the link 8, and then the waterproof door 1 rotates around the pivot 18 of the link 8 as shown in FIG. While pressing the rubber packing 13 in the direction of the door stop 3, the mounting member 4 and the inclined portions 5 and 7 of the fixed base 6 come into contact with each other, and the waterproof door 1 is in an upright state.

  At this time, since the mounting member 4 provided on the waterproof door 1 does not interrupt between the fixed base 6 provided on the storage box 2 and the rubber packing 13, the waterproof door 1 is pressed in the door contact direction, and the waterproof door The watertightness of 1 and 3 per door will be improved. The stopper 16 has an effect of preventing unnecessary interruptions.

  The operation from the standing state to the lying down state is the reverse of the order shown in FIGS. 4 to 7. First, as shown in FIGS. 7 to 6, the link 8 is moved to the stopper 9 around the pivot 18 of the link 8. The waterproof door 1 rotates until it abuts, then pivots about the pivot 17 of the link 8 until the receiving portion 11 abuts on the roller 10, and then moves the waterproof door 1 in the door-to-door direction. The waterproof door 1 is supported by the support member 10 and the support member 12 with 10 ′, and the lying state of FIG. 4 is obtained.

  In this operation, the waterproof door 1 smoothly moves in the door contact direction by the roller 10 ′, and the rubber plate 12 ′ of the roller 10 ′ and the support member 12 causes less impact sound and scratching and can be smoothly laid down. Further, even when the waterproof door 1 is moved backward to the entrance / exit side and then moved up to the entrance / exit side, the rising / lowering operation can be performed without the front edge member 14 contacting the storage case 2.
