It is a top view in the lying down state of the waterproof door device of the present invention. (A) is the XX sectional drawing of FIG. 1, (b) is FIG. 2 (a) equivalent figure in a standing state. It is the YY sectional view taken on the line of Fig.2 (a). FIG. 4 is a sectional view taken along line ZZ in FIG. 3. FIG. 2A is a simplified diagram of FIG. 2A in a lying state, FIG. 2B is a diagram corresponding to (a) in the middle of standing, and FIG. 2C is a diagram corresponding to (a) in the standing state.

  Hereinafter, examples of embodiments of the present invention will be described with reference to the drawings as appropriate. In addition, embodiment of this invention is not limited to the following examples.

  FIG. 1 is a plan view of a waterproof door device 1 according to the present invention in a state where the waterproof door 2 is in a lying position (falling state), and FIG. 2A is a cross-sectional view taken along line XX in FIG. 2 (b) is a view corresponding to FIG. 2 (a) in which the waterproof door 2 is in a standing position (standing state), and FIG. 3 is a cross-sectional view taken along line YY in FIG. 2 (a). .

  The waterproof door device 1 includes a single waterproof door 2 that can rise and fall from a lying state to a standing state, and a case 4 that houses the waterproof door 2 in a lying state. In addition, the left-right length and the water stop height of the waterproof door 2 can be arbitrarily changed. In addition, the number of waterproof doors 2 can be arbitrarily changed, and the plurality of waterproof doors can be arranged in a straight line simply arranged in the left-right direction, arranged in other shapes such as L-shape and U-shape, Some dimensions can be different from others.

  The case 4 is installed on the road surface of the expected flooding road where there is a possibility of flooding. As an example of the road surface of the expected inundation road, a floor surface of an entrance / exit of a building or a parking lot can be given. In the waterproof door device 1, the front and rear are the front side of the standing waterproof door 2 (upper side in FIG. 1, right side in FIG. 2). The left and right sides are viewed from the front. The case 4 can be adapted to the arrangement of the waterproof door 2.

  The upper opening of the case 4 is closed by the waterproof door 2 in a lying state. That is, the fall position of the waterproof door 2 is a position where the opening is closed along the upper opening of the case 4. Here, the waterproof door 2 is in a horizontal position, but may be an inclined surface so as to match the expected flooded road surface. On the other hand, the standing position of the waterproof door 2 is a position fixed at the time of waterproofing, and can be an arbitrary position standing up from the lying down position. However, in general, in order to secure the water stop height as much as possible, This is also the case in this embodiment. In addition, on the front side of the case 4, door frames 8 having columns 6 on both sides that are in contact with the left and right sides of the standing waterproof door 2 are installed. An elastic body 9 is attached to the back side of each column 6. The waterproof door 2 in the standing state is in a state where both sides on the front side are in contact with the elastic bodies 9, and the space between both the columns 6 is closed in a watertight state to prevent water from entering from the front side (front side).

  Further, the hinge mechanism 10 is connected to the front part of the inner bottom surface of the case 4 and the front part of the back side of the waterproof door 2 in the lying state (the lower part on the back side in the standing state). Further, a tension arm 12 is connected to the central portion of the inner bottom surface of the case 4 and the central portion on the back side of the waterproof door 2 in a lying state. Here, the hinge mechanism 10 and the tension arm 12 are installed at two places on the left and right, but may be installed at one place or three or more places, or the number of the hinge mechanism 10 and the tension arm 12 may be changed.

  In addition, a standing assist mechanism 20 is connected to the front part of the inner bottom surface of the case 4 and the rear part of the back side of the waterproof door 2 in a lying state. The standing assist mechanism 20 includes dampers 21A to 21C as three urging members and arms 22A to 22C that are rotatably connected to the dampers 21A to 21C, respectively. The arms 22B and 22C have the same length and are shorter than the arm 22A. In addition, the dampers 21A and 21B have the same length when lying down and standing, and are shorter than the damper 21C. The arms 22 </ b> A to 22 </ b> C are rotatably attached to the case 4 via a common hinge 24. On the other hand, the ends of the dampers 21 </ b> A to 21 </ b> C opposite to the arms 22 </ b> A to 22 </ b> C are rotatably attached to the back surface of the waterproof door 2. Here, the mounting positions of the dampers 21A and 21C with respect to the back surface of the waterproof door 2 are arranged so as to have the same height when standing, and are arranged above the mounting position of the damper 21B. Note that an air damper, an oil damper, a torsion coil spring, or a combination thereof can be employed as the biasing member, and the number of biasing members can be two or less, or four or more.

  It should be noted that the lengths and lengths of the various members can be appropriately changed, such as the lengths of the arms 22B and 22C being different, and the lengths of the dampers 21A and 21B being different. Further, the length of the damper 21A or the like can be changed without changing the length of the arm 22A or the like, or the length of the arm 22A or the like can be changed without changing the length of the damper 21A or the like. Furthermore, after providing the hinge 24 separately, the attachment position with respect to the inner bottom face of the case 4 of the arms 22A to 22C may be moved back and forth, or the attachment position of the damper 21A or the like on the waterproof door 2 may be changed as appropriate.

  4 is a cross-sectional view taken along the line ZZ of FIG. 3 and shows a side view of one hinge mechanism 10. The other hinge mechanism 10 is configured in the same manner as the one hinge mechanism 10.

  The hinge mechanism 10 includes a first base 62 that rotatably supports a first rotating shaft 60 along the left-right direction, a second base 66 that rotatably supports a second rotating shaft 64 along the left-right direction, and a tip (upper end). ) Is connected to the first rotating shaft 60, and has a L-shaped link 68 in a side view when the base end (lower end) is connected to the second rotating shaft 64. The first base 62 is fixed to the lower part of the back surface of the waterproof door 2, and the second base 66 is fixed to the inner bottom front part of the case 4. The hinge mechanism 10 is a single link having no link other than the link 68.

  A protruding plate 70 as a rotation restricting portion is fixed to the lower portion of the waterproof door 2 so as to protrude rearward when standing up (downward when lying down). The protruding height of the protrusion 70 from the rear surface of the waterproof door 2 is such that the waterproof door 2 stands up around the first rotation shaft 60 by a first predetermined rotation angle (for example, 70 degrees) from the lying state. It is supposed to be in contact with the front side. It can be said that the state in which the waterproof door 2 is erected by the first predetermined rotation angle from the lying down state is the state in which the waterproof door 2 is rotated by the first predetermined rotation angle in the direction in which the waterproof door 2 lower part approaches the link 68. In the lying state (from the state rotated by the first predetermined rotation angle), the link 68 takes a posture in which the distal end side is vertical and the proximal end side is horizontal.

  Note that a locking mechanism that locks them together when they come into contact may be provided between the protruding plate 70 (rotation restricting portion) and the link 68. In addition, the lock mechanism can be unlocked when lying down so that the standing angle is equal to or less than the first predetermined rotation angle. Furthermore, instead of the waterproof door 2 side, a rotation restricting portion such as a protrusion may be provided on the link 68 side. In addition, a rotation restricting portion may be provided on the waterproof door 2 and the link 68, and the rotation may be restricted when the rotation restricting portions and the like come into contact with each other.

  The waterproof door device 1 having such a hinge mechanism 10 stands as shown in FIG.

  That is, when the waterproof door 2 in the fall state as shown in FIG. 5A starts to stand, the waterproof door 2 starts to rotate around the first rotation shaft 60 close to itself. Such rotation around the first rotation shaft 60 (first rotation) is performed until the waterproof door 2 rotates by the first predetermined rotation angle and the standing angle reaches the first predetermined rotation angle. During the standing operation, the weight of the waterproof door 2 is supported by the urging force exerted by the standing assist mechanism 20, and the standing operation force is assisted.

  And as shown in FIG.5 (b), when the standing angle of the waterproof door 2 reaches the 1st predetermined rotation angle, the protrusion board 70 of the waterproof door 2 lower part will contact the front end side of the link 68 from the front side, and the waterproof door 2 The first rotation is restricted, and the waterproof door 2 does not perform the first rotation any more. When the standing operation is further performed from this state and a force in the standing direction is applied to the upper side of the waterproof door 2, the waterproof door 2 rotates around the second rotation shaft 64 together with the link 68 (second rotation).

  In addition, when the standing angle of the waterproof door 2 becomes the first predetermined rotation angle or an adjacent angle thereof (for example, any angle within the range of 5 degrees in the front and rear directions), the waterproof door 2 is stopped by the standing assistance mechanism 20. Can be configured. That is, when the damper 21A is already at the maximum length and the arm 22A is floating, when the first predetermined rotation angle or its adjacent angle (stop angle) is reached, the damper 21B is also at the maximum length so that the arm 22B starts to float. When standing up as described above, only the damper 21C exerts an urging force. Adjust the weight of the waterproof door 2 (component force of gravity at the standing angle), the maximum length and biasing force of the dampers 21B and 21C, the length of the arms 22B and 22C, the mounting position of the dampers 21B and 21C with respect to the waterproof door 2, etc. If the relationship is such that the urging force is switched and balanced at the stop angle, the waterproof door 2 can be temporarily stopped at the stop angle.

  The second rotation continues from the first predetermined rotation angle to the second predetermined rotation angle (the angle at which the device stands up, the angle at the upright position, here 90 degrees), and as shown in FIG. In addition, the waterproof door 2 is in an upright state.

  Since the first rotation is performed around the first rotation shaft 60 on the waterproof door 2 side, the first rotation is performed in a state in which interference with the case 4 and the column 6 is prevented. On the other hand, since the second rotation is performed around the second rotation shaft 64 on the case 4 side below the waterproof door 2, the entire waterproof door 2 rotates so as to approach the support column 6, and the support column 6 as a whole at the end of the standing state. Thus, the waterproof door 2 can be erected in a state where the adhesiveness is excellent as a whole, and can be erected in a highly watertight state.

  On the other hand, the transition from the standing state to the lying state by the lying down operation is performed in the opposite manner to the case of the standing up operation. That is, the second rotation is performed from the standing position (second predetermined rotation angle) to the first predetermined rotation angle, and the first rotation is performed from the first predetermined rotation angle to the lying position (standing angle 0 degree). Further, the waterproof door 2 is temporarily stopped at a stop angle near the second predetermined rotation angle.

  The waterproof door device 1 according to the present invention includes a waterproof door 2 provided so as to be able to rise and fall with respect to the case 4 from a lying position to a standing position, a first rotating shaft 60 provided on the waterproof door 2 side, and the case 4. The second rotary shaft 64 provided on the side and a link 68 connecting the first rotary shaft 60 and the second rotary shaft 64 are provided, and the waterproof door 2 rotates around the first rotary shaft 60 by a predetermined rotation angle. Then, the protrusion 68 which contacts the link 68 and regulates the rotation exceeding the predetermined rotation angle around the first rotation shaft 60 is included.

  Therefore, the hinge mechanism 10 can be a single link type, and the structure can be simplified as compared with the multi-link type, as well as the manufacturing cost and the failure rate reduction and easy repair. Maintenance costs can be reduced by making it easier. In addition, by shifting from the first rotation to the second rotation, it is possible to realize an appropriate operation of the waterproof door such as an interference prevention operation and a pressing operation with respect to the case 4 and the door frame 8. Then, by adjusting the size and shape of the link, the degree of protrusion of the protruding plate 70, etc., the first predetermined rotation angle that shifts from the first rotation to the second rotation can be adjusted. Can be easily and accurately tuned.

  Further, when the standing angle of the waterproof door 2 is in the range from the lying position to the first predetermined rotation angle, the waterproof door 2 is rotated around the first rotation shaft 60, and the standing angle of the waterproof door 2 is the first predetermined angle. In the range from the rotation angle to the standing position, the waterproof door 2 is rotated around the second rotation shaft 64 and the link 68 is L-shaped in a side view. Therefore, it is possible to perform an appropriate operation while further reducing the cost, and to further facilitate the design.
