Description

[Technical field]

[0001] The present invention relates to a liquid infiltration prevention device for blocking a gap that occurs between an opening, such as a doorway or window of a building, and the edge of a closing body for closing said opening, such as the lower edge of a door or storm shutter, in order to prevent various liquids, such as rainwater, from infiltrating through said gap. [Background technology]

[0002] The liquid ingress prevention device of the present invention is intended to prevent the ingress of various liquids through gaps that occur between an opening and the edge of a closure used to close it, but in this application, we will particularly explain the case where the opening is a doorway to a building and the closure is a door, by closing the gap between the doorway and the lower edge of the door to prevent rainwater from entering the building through the gap.

[0003] There are gaps between the doorway and the door to allow smooth opening and closing of the door, to allow air to circulate, etc. In such cases, rainwater may seep into the house through the gaps even when the door is closed. This problem is particularly noticeable when the wind and rain are strong, such as during a typhoon.

[0004] In the above cases, it is common to pile sandbags on the exterior side of the door to close the gap. However, preparing sandbags and soil to make sandbags is time-consuming and requires a large space. It also takes a lot of time and effort to make sandbags and pile them up, and it also takes a lot of time and effort to remove the sandbags and dismantle them after the wind and rain have stopped. It is particularly difficult for elderly people with weakened muscles and people with physical disabilities to perform such work.

[0005] Therefore, a liquid ingress prevention device has been proposed for blocking a gap between an opening and the edge of a closing body for closing the opening to prevent ingress of various liquids through the gap. That is, it is a simplified waterproofing device consisting of a waterstop formed with an L-shaped cross section by raising a waterstop section from the rear edge of a horizontal plate section placed on the floor surface of the entrance, and at least a pair of fixing weights placed on the horizontal plate section and abutting their rear sections against the front surface of the waterstop section to fix the waterstop in a fixed position, the waterstop has an elastic seal attached across the entire width of the lower surface of the horizontal plate section, and elastic seal members are attached vertically to both sides on the back surface of the waterstop section, and when used, the waterstop is temporarily placed at a predetermined position on the floor surface of the entrance. A simplified waterproofing device has been proposed in which a pair of fixed weights are then placed on the left and right side edges of the waterstop portion of the waterstop, and the weight of the fixed weights presses and adheres the elastic sealing material attached to the underside to the entrance floor surface, while at the same time pressing the rear ends of the fixed weights against the front faces of the left and right side edges of the waterstop portion, thereby pressing and adhering the elastic sealing materials attached to each of the back faces to the front faces of the left and right side portions of the entrance opening, thereby preventing water from entering the entrance opening (see, for example, Patent Document 1 below).

[0006] In addition, a tape-like member for sealing gaps in building fixtures has also been proposed, in which a relatively thick elastic member is attached to the surface of a flexible and bendable band-shaped support member, and an adhesive layer is formed on the surface of the band-shaped support member on both sides of the elastic member (see, for example, Patent Document 2 below).

[0007] Furthermore, a waterproof device has been proposed (see, for example, Patent Document 3 below), which includes a pair of left and right holders, a waterproof sheet whose left and right edges are held by the pair of left and right holders in a state extending in the vertical direction and whose lower part extends along the floor surface in this held state, and a pressing means for pressing the lower part of the waterproof sheet downward while held by the pair of left and right holders to adhere it to the floor surface.

[0008] The liquid infiltration prevention devices according to the above-mentioned conventional technology require less preparation time and space for installation than the above-mentioned sandbag stacking, and their installation and removal also require less labor and time than the production, installation, removal and dismantling of sandbags.

[0010] However, in the liquid infiltration prevention devices according to the above-mentioned conventional technology, new gaps are generated between the opening or the edge of the closure body and the blocking body, and various liquids may seep in through these gaps. Therefore, the first problem that the present invention aims to solve is to provide a liquid infiltration prevention device that can more effectively prevent the infiltration of various liquids through gaps generated between an opening and the edge of a closure body for closing the opening in order to prevent the infiltration of various liquids through these gaps.

[0011] In addition, in the above-mentioned conventional liquid infiltration prevention devices, when they are placed on an opening, there is a risk that they will be washed away, especially when the wind and rain are strong, such as during a typhoon. Therefore, the second problem that the present invention aims to solve is to provide a liquid infiltration prevention device that can be attached more firmly to a closing body for closing a gap that occurs between an opening and the edge of a closing body for closing the opening in order to prevent various liquids from infiltrating through the gap.

[0012] Furthermore, in the liquid infiltration prevention devices according to the above-mentioned conventional technology, multiple weights are placed on the upper surface of a water stop plate with an L-shaped cross section (see, for example, the above-mentioned Patent Document 1), attached to the lower edge of a door (see, for example, the above-mentioned Patent Document 2), or a water stop sheet is sandwiched between a holder and then screwed to an opening with multiple knob nuts (see, for example, the above-mentioned Patent Document 3), which are complicated structures, and therefore their installation and removal require time and effort. Therefore, the third problem that the present invention aims to solve is to provide a liquid infiltration prevention device that can be installed and removed more easily for blocking a gap that occurs between an opening and an edge of a closing body for closing the opening in order to prevent various liquids from infiltrating through the gap. [Means for solving the problem]

[0013] The present invention has been proposed to solve the above problems, and has the following configuration. In the following, the numbers and symbols shown in the drawings attached to this application will be described together to help understand the configuration of the present invention.

[0014] The liquid ingress prevention device (A) according to claim 1 is a liquid ingress prevention device for blocking a gap (D) that occurs between an opening (B) and an edge of a closing body (C) for closing the opening (B) to prevent various liquids such as rainwater from ingressing through the gap (D), and includes a waterproof member (1), a fastening member (2), a first support member (3), a second support member (4), a connecting member (5), and a fixing member (6). The waterproof member (1) is a member for preventing ingress of liquid by blocking the gap (D) by abutting across the opening (B) and the closing body (C), and is made of a waterproof and elastic material, and is provided along the length direction of the first support member (3) so as to face the gap (D). The fastening member (2) is a member for fastening the liquid ingress prevention device (A) to the closing body (C), and is provided on the second support member (4) so ​​as to be rotatable in the vertical direction. The first support member (3) is a member for supporting the waterproof member (1) and is an elongated member provided parallel to the gap (D). The second support member (4) is a member for supporting the fastening member (2) and is an elongated member provided parallel to the first support member (3). The connecting member (5) is a member for connecting the first support member (3) and the second support member (4) and is configured to be rotatable in the vertical direction around the second support member (4) as an axis. The fixing member (6) is a member for pressing the waterproof member (1) and the first support member (3) toward the gap (D) to fix them, and is provided on the second support member (4).

[0015] The liquid infiltration prevention device (A) according to claim 2 is the liquid infiltration prevention device (A) described in claim 1, in which the first support member (3) and / or the second support member (4) are formed by an extendable rod-shaped member. Effect of the Invention

[0016] The liquid intrusion prevention device (A) according to the present invention has the above-mentioned configuration and can provide the following effects.

[0017] First, in the liquid infiltration prevention device (A) according to claim 1, the waterproof member (1) closing the gap (D) is supported by the first support member (3), which is a long member provided parallel to the gap (D), and since the waterproof member (1) can be prevented from twisting or bending, it is possible to more effectively prevent the infiltration of various liquids from the gap (D). Therefore, the liquid infiltration prevention device (A) according to claim 1, which is for a liquid infiltration prevention device for closing a gap between an opening and an edge of a closing body for closing the opening in order to prevent the infiltration of various liquids from the gap, can solve the first problem that the present invention aims to solve, which is to provide a liquid infiltration prevention device that can more effectively prevent the infiltration of various liquids from the gap.

[0018] In addition, the liquid infiltration prevention device (A) according to claim 1 can be more firmly attached to the closure body (C) because the fastening member (2) is attached to the closure body (C) and the fixing member (6) presses the waterproof member (1) and the first support member (3) toward the gap (D) to fix them. Therefore, the risk of the liquid infiltration prevention device (A) being washed away can be reduced, especially when wind and rain are strong, such as when a typhoon is approaching. Therefore, the liquid infiltration prevention device (A) according to claim 1 can solve the second problem that the present invention aims to solve, which is to provide a liquid infiltration prevention device that can be more firmly attached to a closure body for closing a gap that occurs between an opening and an edge of a closure body for closing the opening to prevent various liquids from infiltrating through the gap.

[0019] Furthermore, since the liquid infiltration prevention device (A) according to claim 1 has a compact configuration as described above, it does not require much preparation time and does not require a large space compared to the conventional method of piling sandbags or the conventional liquid infiltration prevention devices. Furthermore, the installation and removal of the liquid infiltration prevention device (A) requires less effort and time compared to the conventional method of piling sandbags or the conventional method of installing and removing the liquid infiltration prevention device. Therefore, the liquid infiltration prevention device (A) according to claim 1 can solve the third problem that the present invention aims to solve, which is to provide a liquid infiltration prevention device that can be installed and removed more easily for blocking a gap that occurs between an opening and an edge of a closing body for closing the opening to prevent the infiltration of various liquids through the gap.

[0020] In particular, the liquid ingress prevention device (A) of claim 2 is preferable because the first support member (3) and / or the second support member (4) are extendable rod-shaped members, allowing the user to adjust their length by extending or retracting them to match the width of the opening (B) or closure (C), for example. [Brief description of the drawings]

[0021] [Figure 1] 1 is a diagram illustrating the function and effect of a liquid intrusion prevention device according to an embodiment of the present invention. [Diagram 2] FIG. 2 is a side view of FIG. [Diagram 3] FIG. 3 is a partial cross-sectional view of FIG. 2. [Figure 4] 3 is a reference diagram illustrating a state in which the fastening member in FIG. 2 has been removed. FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] The structure of a liquid infiltration prevention device (A) according to one embodiment of the present invention will be described below with reference to the attached drawings. The liquid infiltration prevention device (A) is a liquid infiltration prevention device for closing a gap (D) that occurs between an opening (B) such as a doorway or window of a building and an edge of a closing body (C) for closing the opening (B) such as the lower edge of a door or storm shutter, in order to prevent various liquids such as rainwater from infiltrating through the gap (D), and has a waterproof member (1), a fastening member (2), a first supporting member (3), a second supporting member (4), a connecting member (5), and a fixing member (6) as shown in Figures 1 to 4.

[0023] The liquid infiltration prevention device (A) is intended to prevent the infiltration of various liquids through the gap (D) that occurs between an opening (B) and the edge of a closing body (C) that closes it, but the following will be explained as an example of a case in which the opening (B) is a doorway of a building and the closing body (C) is a door, and the gap (D) that occurs between the doorway (B) and the lower edge of the door (C) is closed to prevent rainwater from infiltrating from the outdoors into the indoors through the gap (D). Note that while only one liquid infiltration prevention device (A) is installed in the figure, two or more can be installed to match the width of the doorway (B) and / or door (C).

[0024] 1 to 4, the waterproof member (1) is a member for preventing liquid from entering by abutting across the opening (B) and the closure (C) to close the gap (D), and is made of a waterproof and elastic material and is provided so as to face the gap (D) along the length direction of the first support member (3). Specifically, various known rubber materials, such as a long member that is L-shaped in vertical cross section and made of waterproof elastic rubber, can be used as the waterproof member (1).

[0025] As shown in Figs. 1 to 3, the fastening member (2) is a member for fastening the liquid intrusion prevention device (A) to the closure body (C), and is provided on the second support member (4) so ​​as to be rotatable in the vertical direction. Specifically, the fastening member (2) may be a suction cup-shaped attachment, which is composed of a suction cup portion (2a) and a base portion (2b), in which the suction cup portion (2a) is attached to the base portion (2b), and the base portion (2b) has a through hole for inserting the second support portion (4). If the closure body (C) is made of a magnetic material such as iron, a magnet attachment may be used as the fastening member (2). It is also preferable that the fastening member (2) is slidable on the second support member (4) so ​​that the user can adjust its position. The number and position of the fastening members (2) are not particularly limited, but it is preferable to provide them in two locations at both ends of the liquid ingress prevention device (A), which allows the liquid ingress prevention device (A) to be stably fastened to the closure body (C).

[0026] As shown in Figs. 1 and 4, the first support member (3) is a member for supporting the waterproof member (1) and is an elongated member provided parallel to the gap (D). Specifically, a cylindrical elongated member can be used as the first support member (3), but is not particularly limited thereto. Also, the first support member (3) may be any of various known telescopic rod-shaped members consisting of a thick-diameter rod-shaped member having a storage section and a thin-diameter rod-shaped member one end of which is stored in the thick-diameter rod-shaped member. By using such a telescopic rod-shaped member, the user can suitably adjust its length by adjusting it to the width of the opening (B) or the closure (C), which is preferable.

[0027] The first support member (3) has a waterproof member (1) attached to its outer circumferential surface facing the opening (B) and the closure (C). The waterproof member (1) may be fixed to the first support member (3), but it may be structured so as to be detachable so that the user can assemble and use the liquid intrusion prevention device (1) when using it. In the figure, the waterproof member (1) is supported over the entire length of the first support member (3), but it is not necessarily required to be supported in this way, and it may be supported over a part of its length.

[0028] As shown in Figures 1 and 4, the second support member (4) is a member for supporting the fastening member (2) and is an elongated member provided in parallel to the first support member (3). As the second support member (4), specifically, a cylindrical elongated member can be used like the first support member (3), but is not particularly limited. Also, as the second support member (4), like the first support member (3), it is preferable to use various known telescopic rod-shaped members so that the user can adjust the length according to the width of the opening (B) or the closure (C).

[0029] As shown in Figures 1 to 4, the connecting member (5) is a member for connecting the first support member (3) and the second support member (4), and is configured to be rotatable in the vertical direction around the second support member (4) as an axis. Specifically, a box-shaped member having a generally U-shape in vertical cross section is connected to the connecting member (5), and both ends of the first support member (3) are attached to the inside of the connecting member (5), and both ends of the second support member (4) are rotatably attached to the inside of the connecting member (5). The number and positions of the connecting members (5) are not particularly limited, but it is preferable to attach a total of two fastening members (2) to both ends of the first support member (3) and the second support member (4), respectively, so that they can be moved stably and smoothly.

[0030] As shown in Figs. 1 and 4, the fixing member (6) is a member that presses the waterproof member (1) and the first support member (3) toward the gap (D) to fix them, and is provided on the second support member (4). Specifically, the fixing member (6) has a pressing member (6a) and an attachment member (6b). The pressing member (6a) is a member that presses the waterproof member (1) and the first support member (3) toward the gap (D) by a biasing means such as a spring, and is a member that can perform pressing by the biasing means and release it by operating the locking bolt. The attachment member (6b) is a ring-shaped member through which the second support member (4) is inserted and attached to it so as to be rotatable. The number and positions of the fixing members (6) are not particularly limited, but it is preferable to provide two of them at both ends of the liquid ingress prevention device (1) to stably bring the waterproof member (2) into close contact with the edge of the closing body (C). Moreover, it is preferable that the fixing member (6) is structured so as to be slidable on the second support member (4), so that its position can be adjusted.

[0031] The above is a description of the structure of the liquid infiltration prevention device (A) according to one embodiment of the present invention. Next, a description will be given of how to use the liquid infiltration prevention device (A) according to one embodiment of the present invention.

[0032] When the first support member (3) and the second support member (4) are telescopic rod-shaped members as described above, the user telescopically adjusts their length to fit the width of the opening (B) or the closure (C). When the waterproof member (1) and the first support member (3) have a detachable structure as described above, the user attaches the waterproof member (1) onto the outer circumferential surface of the first support member (3). When the fastening member (2) and / or the fixing member (6) have a structure that allows them to slide on the second support member (4) as described above, the user moves them to the desired position.

[0033] First, a scene where a user installs the liquid intrusion prevention device (A) will be described. As shown in Figs. 1 to 4, the user installs the liquid intrusion prevention device (A) by fastening the fastening member (2) at a desired position on the closure body (C). When using the above-mentioned suction cup-shaped attachment as the fastening member (2), the user attaches the liquid intrusion prevention device (A) by adsorbing the suction cup part (2a) to the door (C). The fastening member (2) is provided on the second support member (4) so ​​as to be rotatable in the vertical direction, and the connecting member (5) is configured so as to be rotatable in the vertical direction about the second support member (4) as an axis. Therefore, with the fastening member (2) attached to the closure body (C), the connecting member (5) rotates about the second support member (4) as an axis, and moves the first support member (3) in the direction of the gap (D). At this time, the bottom surface of the base (2b) of the fastening member (2) on the closure (C) side comes into contact with the top surface of the second support member (3). Then, the waterproof member (1) attached to the first support member (3) comes into contact across the opening (B) and the closure (C), thereby closing the gap (D). If the opening (B) is a doorway and the closure (C) is a door, the user may install the liquid intrusion prevention device (A) on either the outdoor side or the indoor side of the door.

[0034] 1 to 4, the user operates the fixing member (6) to press and fix the waterproof member (1) and the first support member (3) in the direction of the gap (D). Specifically, the user rotates the mounting member (6b) to orient the pressing member (6a) toward the waterproof member (1) and the first support member (3), operates the locking bolt to start pressing by the biasing means, and presses the waterproof member (1) and the first support member (3) in the direction of the gap (D) to fix them.

[0035] In the liquid ingress prevention device (A) installed as described above, the waterproof member (1) blocking the gap (D) is supported by the first support member (3), which is a long member arranged parallel to the gap (D). Since this prevents the waterproof member (1) from twisting or bending, it is possible to more effectively prevent the ingress of various liquids through the gap (D).

[0036] Furthermore, the liquid ingress prevention device (A) installed as described above has the fastening member (2) fastened to the closure body (C), and the fixing member (6) presses the waterproof member (1) and the first support member (3) toward the gap (D) to fix them, so that the liquid ingress prevention device (A) can be more firmly attached to the closure body (C). Therefore, even in times of strong winds and rain, such as when a typhoon is approaching, the risk of the liquid ingress prevention device (A) being washed away can be reduced.

[0037] Finally, a scene in which the user removes the liquid ingress prevention device (A) will be described. First, the user releases the fixed state of the waterproof member (1) and the first support member (3) by the fixing member (6). Specifically, the user operates the locking bolt to release the state in which the biasing means presses the waterproof member (1) and the first support member (3) toward the gap (D). Next, the user pulls the fastening member (2) away from the closure body (C) to remove the liquid ingress prevention device (A). Specifically, the user peels the suction cup portion (2a) off the door (C) to remove the liquid ingress prevention device (A).

[0038] As described above, the liquid infiltration prevention equipment (A) has a compact configuration, so compared to the conventional method of piling sandbags or the conventional liquid infiltration prevention equipment, preparation for its installation is not time-consuming and does not require a large space. Furthermore, compared to the conventional method of piling sandbags or the conventional liquid infiltration prevention equipment, installation and removal of the liquid infiltration prevention equipment (A) requires less effort and time.
