Description

The present invention relates to a water stop device that is installed at the entrances of buildings such as facilities, stores, subways, and underground shopping malls to prevent water from entering the building during typhoons, heavy rains, etc.

Conventionally, there are known inventions of water stop devices that prevent water from entering a building by blocking the entrance of the building with a water stop and sealing the gap between the entrance and the water stop with a packing or the like. For example, Patent Document 1 proposes an invention of a water stop device in which the water stop is provided with packing that abuts against the underside and both left and right sides of the entrance of the building, a first pressing mechanism that presses the water stop toward the underside of the entrance and a second pressing mechanism that presses the water stop toward both the left and right sides of the entrance, and the first and second pressing mechanisms are used to press the packing against the entrance.

JP 2020-193517 A

However, the water stop device of Patent Document 1 uses a first pressing mechanism and a second pressing mechanism to press the water stop vertically downward and against both the left and right sides of the building entrance, which requires multiple operations, resulting in a problem that the installation work of the water stop device is time-consuming and laborious.

The object of the present invention is to provide a water stop device that can reduce the effort and time required to install a water stop plate.

In order to solve the above problems, the water stop device of the present invention comprises a post installed at the entrance of a building, a water stop plate, and a mounting fixture for mounting the water stop plate to the post, the mounting fixture including a hook that is hung on the post, an operating part that operates the water stop plate in the vertical direction, a restricting hole that restricts the direction of movement of the water stop plate, and a protrusion that is fixed to the water stop plate and loosely fits into the restricting hole, and the restricting hole includes a curved part that curves from the vertical direction to the horizontal direction.

In this case, the mounting fixture includes a fixed piece fixed to the water stop plate, and the fixed piece includes a retaining hole that holds the operating part so that it can move horizontally. Also, the upright has a slit that receives the hook so that it can move vertically.

The water stop device of the present invention is provided with a mounting fixture, which is provided with a restricting hole that restricts the direction of movement of the water stop plate, and the restricting hole has a curved portion that curves from the vertical to the horizontal direction, so that the water stop plate can be pressed in two different directions, the vertical direction and the horizontal direction, with a single operation. This has the effect of saving time and effort when installing the water stop device, and allowing the water stop plate to be installed quickly.

FIG.

An embodiment of a water stop device according to the present invention will be described below with reference to the drawings. In the following description, the side where the second packing 32 is attached to the water stop plate 3 will be described as the back surface 1b of the water stop device 1, and the opposite side will be described as the front surface 1a of the water stop device 1. The mounting fixtures 2 are arranged in pairs on both the left and right sides of the water stop plate 3, but since the pair of mounting fixtures 2 are symmetrical, only the mounting fixture 2 on the right side will be described.

The water stop device 1 shown in Figures 1 to 3 is composed of a mullion 4 that is detachably installed at the entrance E of a building, a water stop plate 3 that blocks the entrance E to prevent water from entering, a mounting fixture 2 that attaches the water stop plate 3 to the mullion 4, and a frame 5 on which the water stop plate 3 is placed. In Figure 1, the water stop device 1 is installed inside the entrance E, but it is also possible to install the water stop device 1 outside the entrance E. In this case, when installed inside the entrance E, the front surface 1a is installed so that it faces inside the building, and when installed outside the entrance E, the front surface 1a is installed so that it faces outside the building.

The mullions 4 function as pillars that support the waterstop 3. In addition, a frame 5 on which the waterstop 3 is placed is provided below the mullions 4. Note that the mullions 4 can be made of square pillars, square pipes, extrusion-molded components, etc.

The water stop 3 is composed of a main body 33, a first packing 31 attached to the bottom surface 33b of the main body 33, and a second packing 32 attached to the area where the water stop 3 abuts the upright 4. The first packing 31 is pressed against the frame 5, and the second packing 32 is pressed against the upright 4, so that the water stop 3 is tightly attached to the upright 4 and the frame 5 via the first packing 31 and the second packing 32, and water can be reliably prevented from entering. The first packing 31 and the second packing 32 are made of a flexible material such as rubber or resin. It is also possible to attach a handle (not shown) for carrying to the top surface 33a of the main body 33.

The mounting fixture 2 is composed of a main body 21, a bolt 24 with a knob 24a as an operating part for vertically operating the water stop plate 3, a fixing piece 25 fixed to the water stop plate 3, and a headed protrusion 26 fixed to the water stop plate 3 and loosely fitted into a restricting hole. At this time, the head 26a of the protrusion 26 acts as a member to prevent the main body 21 from coming loose. A bolt screwed into the water stop plate 3 can be used as the protrusion 26.

The fixing pieces 25 are metal pieces with a roughly L-shaped cross section, fixed to both sides of the water stop plate 3 so that the bottom of the L shape forms the top surface 25a. At this time, the top surface 25a is fixed so that it is in the same plane as the top surface 33a of the body 33 of the water stop plate 3. In addition, a slit-shaped retaining hole 25b is formed in the top surface 25a, and the retaining hole 25b holds the bolt 24 so that it can move horizontally toward the front surface 1a or the back surface 1b.

The body 21 of the mounting fixture 2 is formed with a hook 22 that is hooked into a slit 41 formed in the upright 4, and a restricting hole 23 that restricts the movement direction of the water stop 3 is opened at the base end of the hook 22. The restricting hole 23 includes a curved portion 23a that curves from the vertical direction to the horizontal direction.

A groove 21a is formed at the top end of the main body 21 to receive a bolt 24 with a knob 24a, and a nut 21b is formed in the groove 21a to screw the bolt 24. The bolt 24 is inserted into the retaining hole 25b of the fixing piece 25 and screwed into the nut 21b.

The mullion 4 has a slit 41 that receives the hook 22 so that it can move vertically. The slit 41 is formed long in the vertical direction, and the upper end of the slit 41 engages with the hook-shaped portion 22a of the hook 22 when the waterstop 3 is installed (see Figure 4(b)).

Next, the operation of installing the water stop device 1 having the above configuration will be described with reference to Figure 4. First, as shown in Figure 4(a), the water stop plate 3 is placed on the first packing 31, and the hook 22 is inserted into the slit 41 with the second packing 32 lightly abutting against the mullion 4. Then, when the knob 24a of the bolt 24 is rotated forward, the bolt 24 advances deeper into the groove 21a while threading into the nut 21b. Note that forward rotation refers to the direction in which the bolt 24 tightens, and reverse rotation refers to the direction in which the bolt 24 loosens.

At this time, the bolt 24 is held by the fixing piece 25 at the same height as the top surface 33a of the body 33 of the water stop 3. As a result, the body 21 is pulled up vertically relative to the water stop 3, and the hook 22 engages with the upper end of the slit 41. At this time, the slit 41 allows the hook 22 to move vertically, so it does not prevent the body 21 from moving vertically upward.

Next, when the knob 24a of the bolt 24 is further rotated in the forward direction while the hook 22 is engaged with the upper end of the slit 41, the water stop plate 3 is pulled vertically downward relative to the main body 21, the first packing 31 is pressed vertically downward, and the water stop plate 3 is tightly attached to the frame 5. At this time, the protrusion 26 inserted into the restriction hole 23 also moves vertically downward inside the restriction hole 23.

Since the restricting hole 23 is gradually curved horizontally downward, the waterstop 3 also gradually moves horizontally relative to the main body 21, that is, toward the mullion 4 in the rear direction . At this time, the bolt 24 is held by the retaining hole 25b so as to be horizontally movable, and therefore does not impede the horizontal movement of the waterstop 3.

When the knob 24a is turned sufficiently, as shown in FIG. 4(b), the second packing 32 is pressed, and the water stop 3 is in close contact with the upright 4. To release the water stop 3, the knob 24a of the bolt 24 is rotated in the reverse direction. Note that in this embodiment, the protrusion 26 is moved to the end of the restriction hole 23, but it is sufficient that the first packing 31 and the second packing 32 are pressed to an appropriate degree to ensure waterproofing, and the installation can also be completed halfway through the restriction hole 23.

Therefore, according to this embodiment of the water stop device 1, the mounting fixtures 2 are provided on both sides of the water stop plate 3, and the mounting fixtures 2 are provided with restriction holes 23 that restrict the movement direction of the water stop plate 3. The restriction holes 23 are provided with curved portions 23a that curve from the vertical direction to the horizontal direction, so that the pressing force applied in the vertical direction can be changed to a pressing force in the horizontal direction, and pressing force can be applied in multiple directions with a single operation.

In addition, the fixing piece 25 that holds the bolt 24 has a retaining hole 25b that allows the bolt 24 to move horizontally, allowing the water stop plate 3 to move horizontally and reliably pressing the second gasket 32. Furthermore, a slit 41 that engages the hook 22 is formed in the mullion 4, and the slit 41 allows the hook 22 to move vertically, so the hook 22 can be easily attached to and detached from the slit 41.

The present invention is not limited to the above embodiment, and the shape and configuration of each part can be appropriately changed without departing from the spirit of the present invention.
