The side projecting portion 11a is formed so as to project toward the side of the plate body 11, and is inclined so that the projecting width increases upward. A notch-shaped engaging portion 11d is formed on the upper side of the side protruding portion 11a. Further, the front projecting portion 11b is formed so as to project toward the front, which is the surface side of the plate body 11, and, like the side projecting portion 11a, the projecting width expands upward. It is inclined to. The side overhanging portion 11a and the front overhanging portion 11b can be integrally formed, for example, by bending a plate-like body.

  FIG. 3 is an enlarged view showing the vicinity of the side portion of the water stop device shown in FIG. 2. FIG. 4 is an enlarged view showing the vicinity of the lower part in the AA cross section of FIG. As shown in FIGS. 3 and 4, the first water stop material 12 has a protruding portion 12 a that protrudes so as to protrude from the surface side of the plate main body 11. It is interposed between the main body 11 and the floor surface 93. Further, the second water stop material 13 has such a length and arrangement that the lower end extends below the lower end of the plate body 11, and the protruding portion 12 a of the first water stop material 12 is applied to the back surface side. By touching, it curves forward. The third water blocking material 14 is provided on the back side of the plate body 11 so as to extend in the vertical direction.

  As shown in FIG. 2, the pair of guide rails 20 and 30 are configured to be bilaterally symmetric with each other. The rail main bodies 21 and 31 for guiding the water stop plate 10 and the rail main bodies 21 and 31 are provided inside. The lock members 22 and 32 are attached. The rail bodies 21 and 31 are formed in a U shape in plan view and extend in the vertical direction, and are arranged so that the U-shaped openings face each other. The lock members 22 and 32 are formed by bending a leaf spring-like member, and the vertical position of the water stop plate 10 is fixed by engaging with the engaging portion 11 d at the lowered position of the water stop plate 10. The The lock members 22 and 32 function as side edge pressing members provided on the rail bodies 21 and 31 so as to engage with the side edges of the water blocking plate 10.

  FIG. 5 is an enlarged view showing the vicinity of the upper portion of the guide rail 30 in the BB cross section of FIG. 3. One end of the lock member 32 is fixed to the inner surface of the enlarged upper portion of the rail body 31. On the other end side of the lock member 32, a locking portion 32a bent downward is provided. The locking portion 32a protrudes to the outside through an opening 31a formed on the side wall of the rail body 31.

  As shown in FIG. 5A, when the water stop plate 10 is lowered in the direction of the arrow, the lock member 32 is laterally stretched as a side edge portion of the water stop plate 10 in a state where elastic deformation is maintained. The sliding contact with the protruding portion 11a. When the water stop plate 10 is lowered to the lowered position, the lock member 32 engages with the engaging portion 11d of the water stop plate 10 as shown in FIG. 5B, and the position of the water stop plate 10 is fixed. The locking portion 32 a of the lock member 32 is locked to the outer surface of the rail body 31.

  In the water stop device 1 having the above configuration, when the water stop plate 10 is lowered to the lowered position, the lower surface of the first water stop material 12 contacts the floor surface 93 as shown in FIG. Further, the second water-stopping material 13 comes into contact with the projecting portion 12 a of the first water-stopping material 12 on the back surface side, and the tip portion comes into contact with the floor surface 93. In this state, when water W stays on the surface side (outdoor side) of the water stop plate 10 due to heavy rain or the like, a pressing force F as shown by an arrow acts on the second water stop material 13 due to water pressure. The protruding portion 12 a is pressed and comes into close contact with the floor surface 93. In this way, entry of water from below the water stop plate 10 is reliably prevented. In order to prevent the protrusion 12a from rising and to ensure water stoppage, it is preferable to provide the second water stop material 13 as in this embodiment, but the second water stop material 13 is not provided. However, it is possible to stop water by applying a pressing force by water pressure to the protruding portion 12a.

  Moreover, since the front overhang | projection part 11b of the water stop board 10 shown in FIG. 3 is formed so that the overhang width may become large upwards, if the water stop board 10 is lowered | hung to a descent | fall position, a board main body 11 is pressed toward the rear (back side) by the contact between the inner surface of the rail body 31 and the front overhanging portion 11 b, and the upper part of the third water blocking material 14 is in close contact with the inner surface of the rail body 31. As shown in FIGS. 3 and 4, the pair of guide rails 20 and 30 are formed in a gradient shape on the lower inner surface of the rail bodies 21 and 31 so that the protruding width gradually increases downward. The surface side pressing members 23 and 33 are provided, and when the surface side pressing members 23 and 33 slide on the surface side of the plate main body 11, the lower part of the third water blocking material 14 is placed on the inner surface of the rail main body 31. In close contact. Further, when water stays on the surface side of the water stop plate 10, the plate main body 11 receives a pressing force, and the lower part of the third water stop material 14 comes into close contact with the inner surface of the rail main body 31.

  Thus, even if the board main body 11 is lightweight, the water stop board 10 of this embodiment is between the 1st water stop material 12 and the floor surface 93, and the 3rd water stop material 14 and a rail. Since the inner surface of the main body 31 can be reliably brought into close contact with each other, it is possible to reliably prevent water from entering through the entrance / exit 92 while improving the handleability.

  In addition, the water stop plate 10 is fixed when the engaging portions 11d and 11d formed on the laterally protruding portions 11a and 11a on both sides are engaged with the lock members 22 and 32, respectively, in the lowered position. The operator can easily confirm that the water stop plate 10 has been reliably lowered to the lowered position, and can prevent a third party from unintentionally removing the water stop plate 10.

  FIG. 5B shows a state where the lock member 32 is engaged with the engaging portion 11d. The engagement between the lock member 32 and the engaging portion 11d can be released by strongly pressing the upper portion of the lock member 32 downward. This operation can be easily performed by using a dedicated unlocking tool described later.

  FIG. 6 is a plan view showing an embodiment of the unlocking tool, and FIG. 7 is a cross-sectional view taken along the line CC in FIG. As shown in FIGS. 6 and 7, the lock release tool 40 has a grip 42 on the upper part of a main body 41 formed in a bent shape. A pressing portion 41a extending downward from the bent portion of the main body 41 is divided by a notch portion 41b. Slit-like engaging portions 41c and 41d extending in the width direction are provided at the upper portion of the main body 41 and the tip portion of the pressing portion 41a, respectively.

  When the unlocking tool 40 is inserted into the upper portion of the guide rail 30 from above as shown in FIG. 8A with the notch 41b aligned with the laterally protruding portion 11a of the plate body 11, the pressing portion 41a The lower end abuts on the upper part of the lock member 32 on both sides of the side projecting portion 11a and presses the lock member 32 downward. As a result, the lock member 32 is elastically deformed to the state shown in FIG. 8B, and the engagement with the engaging portion 11d is released. Thus, by using the lock release tool 40, the water stop plate 10 can be removed quickly and easily.

  As shown in FIG. 8 (a), when the convex engaging portions 31b and 31c are provided on the guide rail 30, these engaging portions are inserted when the unlocking tool 40 shown in FIG. 8 (b) is inserted. 31 b and 31 c can be engaged with the engaging portions 41 c and 41 d of the lock release tool 40. Thereby, since the lock release tool 40 is hold | maintained at the guide rail 30, and the state by which the lock by the lock member 32 was released can be maintained, the removal of the water stop board 10 can be performed more easily.

  As mentioned above, although one Embodiment of this invention was explained in full detail, the specific aspect of this invention is not limited to the said embodiment. For example, a plurality of water stop plates 10 of the present embodiment are prepared, and as shown in FIG. 9, another water stop plate is provided for one water stop plate 10-1 supported by a pair of guide rails 20 and 30. You may comprise so that several water stop board 10-1, 10-2 may be connected up and down by dropping the board 10-2 to the arrow direction. In this case, the first water stop plate of the upper water stop plate 10-2 is formed so that the thickness of the lower water stop plate 10-1 is larger than the thickness of the upper water stop plate 10-2. Sufficient space for the material 12 to adhere to the upper end surface of the lower water stop plate 10-1 can be easily secured, and water enters between the two water stop plates 10-1 and 10-2. Can be surely prevented.

  Moreover, in this embodiment, although the whole bottom face of the 1st water stop material 12 is formed so that it may closely_contact | adhere with the floor surface 93, the shape is not specifically limited. For example, as shown in FIG. 10, the front part and the rear part of the first water-stopping material 12 are folded back through the adjusting members 12b and 12c, respectively, and the central part of the first water-stopping material 12 is pressed by the pressing plate 12d. You may press and fix to the board main body 11. FIG. According to this configuration, even when the floor surface 93 is inclined, the thickness of each of the adjusting materials 12b and 12c is appropriately adjusted according to the inclination angle of the floor surface 93, so that the front and rear of the first water stop material 12 are placed on the floor. The contact with the surface 93 is possible, and the degree of freedom of installation can be increased.

  Moreover, in this embodiment, although the both sides of the water stop board 10 are comprised so that a pair of guide rails 20 and 30 can raise / lower freely, for example, as shown in FIG. By forming a notch-like engagement portion 15a in the engagement block 15 provided on one or both sides of the engagement portion 15 and engaging the engagement portion 15a with a protrusion 93a such as a bolt protruding from the floor surface 93. It is also possible to install the water stop plate 10 without providing the pair of guide rails 20 and 30. In addition, in FIG. 9 to FIG. 11, the same code | symbol is attached | subjected to the component similar to the water stop apparatus 1 shown to FIG. 1 to FIG.

  Moreover, in this embodiment, although the 1st water stop material 12 and the 2nd water stop material 13 are comprised as a separate member which can be isolate | separated, the 1st water stop material 12 is 2nd in the protrusion part 12a. The structure integrated with the water stop material 13 may be sufficient.

  FIG. 12 is a front view of a water stop device according to still another embodiment of the present invention. Moreover, FIG. 13 is a principal part top view of the water stop apparatus shown in FIG. 12, and FIG. 14 is an enlarged view which shows the lower part vicinity in the DD cross section of FIG. The water stop device 1 shown in FIGS. 12 to 14 does not fix the position of the water stop plate 10 while the side edge pressing members 22 and 32 engage with the side edges of the water stop plate 10, respectively. This is different from the lock member of the above embodiment. The side edge portion pressing members 22 and 32 of the present embodiment are block-like members fixed to the inner surfaces of the rail bodies 21 and 31 of the pair of guide rails 20 and 30.

  Further, the water stop device 1 is provided with guide members 16 and 16 on both sides of the surface of the plate body 11 of the water stop plate 10.

The members 23 and 33 are engaged. The surface-side pressing members 23 and 33 are formed in a gradient so that the protruding width gradually increases downward.

  The height positions of the side edge pressing members 22 and 32 and the surface side pressing members 23 and 33 in the rail main bodies 21 and 31 are not particularly limited, but are below the rail main bodies 21 and 31 (for example, in the lowered position). It is preferable to provide a certain water stop plate 10 below the central portion in the height direction. Thereby, since the favorable water stop effect is acquired in the lower part of the water stop board 10, the water immersion from the downward direction of the water stop board 10 can be prevented more reliably. Further, by providing the side edge pressing members 22 and 32 and the surface side pressing members 23 and 33 at the lower part of the rail main bodies 21 and 31, the water stop plate 10 is attached to the rail main bodies 21 and 31, as shown in FIG. On the other hand, when attaching from the lateral direction indicated by the arrow (horizontal direction), the water stop plate 10 interferes with the side edge pressing members 22 and 32 and the surface side press members 23 and 33 without lifting the water stop plate 10 high. Since it can prevent, it can reduce a work burden.

  Also about this water stop apparatus 1, as shown in FIG. 16, the some water stop plates 10-1 and 10-2 can be comprised so that connection up and down is possible. In this case, it is preferable to provide a plurality of side edge pressing members 22, 32 and front surface pressing members 23, 33 on the rail bodies 21, 31 so as to engage with the side edges and the surface side of each water blocking plate 10. . FIG. 16 shows a case where the water stop plate 10-2 is inserted into the rail main bodies 21 and 31 from above, but the interval between the upper and lower side edge pressing members 22 and 32 and the surface side pressing members 23 and 33 is shown. By making this larger than the height of the water stop plate 10-1, each water stop plate 10-1, 10-2 can be attached to the rail bodies 21, 31 from the lateral direction (horizontal direction). Mounting pins 17 and 17 are provided above the water blocking plates 10-1 and 10-2, and the mounting pins 17 and 17 of the lower water blocking plate 10-1 are connected to the upper water blocking plate 10-2. By inserting into the insertion hole (not shown) formed in the lower end surface of the water stop plate 10-1, 10-2 can be more reliably maintained.

  As shown in FIG. 17, a support plate 18 that protrudes forward from the surface of the plate body 11 is provided on the top of the water stop plates 10-1 and 10-2. The water stop material 12 may be configured to be in close contact with the upper surface of the support plate 18 of the lower water stop plate 10-1. According to this configuration, since the upper and lower water stop plates 10-1 and 10-2 can be made the same size and shape, the water stop plates 10-1 and 10-2 are attached to the rail bodies 21 and 31. There is no need to worry about the order, and workability can be improved.
