Description

[Technical Field]

[0001] The present invention relates to a protective fence to be installed near an automatic door unit or the like. [Background technology]

[0002] When rising water caused by a typhoon or heavy rain enters the opening of a building or underground passage, it may cause serious damage due to flooding. Therefore, in cases where such a situation is anticipated, a prior art technique is known in which a water stop is attached to the opening to prevent water from entering (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2022-51357 Summary of the Invention [Problem to be solved by the invention]

[0004] When installing a water stop in an opening, a fixing member such as a mounting bracket may be used separately from the water stop. Furthermore, since water stops are used when water needs to be stopped during floods caused by typhoons or heavy rain, they are normally stored in a storage location such as a warehouse. However, since other items are also stored in storage locations such as warehouses, there are limitations on the storage space available for storing waterstops and fixing members together. Furthermore, if the waterstops and fixing members are stored in separate locations, there is a risk that the fixing members may be lost depending on the storage conditions, and there is room for improvement in the storage of waterstops and fixing members.

[0005] The present invention has been made in consideration of the above circumstances, and its object is to provide a protective fence that allows for convenient storage of water stops and fixing members such as mounting brackets. [Means for solving the problem]

[0006] In view of the above problems, one aspect of the present invention is provided with the following configuration. A protective fence having a storage function for storing a water stop plate that is installed to cover an opening in a structure and a fixing member for installing and fixing the water stop plate to an installation surface, characterized in that the protective fence has an attachment portion for detachably attaching the water stop plate and a storage portion for storing the fixing member. [Effects of the Invention]

[0007] Since the present invention is configured as described above, the protective fence can be used to conveniently store waterstops and fixing members such as mounting brackets. [Brief explanation of the drawings]

[0009] (First embodiment) Next, an embodiment of the present invention will be described. First, an example of installing a safety fence on an automatic door system 1 will be described. Fig. 1 is a schematic front view of an example of the installed safety fence according to the present invention, seen from the indoor side.

[0010] As shown in Figure 1, the automatic door system 1 comprises an opening and closing door 2, a wall 3, and a door activation sensor (not shown) for activating the opening and closing of the opening and closing door 2. The wall 3 may be any material that forms the wall surface of a building, and may be made of glass, concrete, wood, etc. The door activation sensor (not shown) may be, for example, an infrared motion sensor, a touch sensor, or the like.

[0011] In addition, a protective fence 10 is installed facing the wall surface 3 near the automatic door system 1 to prevent people or objects from colliding with the opening and closing doors 2 moving along the wall surface 3. Note that while Fig. 1 shows an example of a double-door system with two opening and closing doors 2, two walls 3, and two protective fences 10, the present invention is not limited to this example. It can also be applied to single-doors and the like, in addition to double-doors.

[0012] (protective fence) An example of the configuration of a protective fence according to the present invention will be described below. Fig. 2 is a schematic perspective view showing an example of a protective fence according to the present invention in an exploded state, and Fig. 3 is a schematic plan view showing an example of the arrangement of waterstops relative to the posts of the protective fence.

[0013] The protective fence 10 is installed on the floor (fixed portion) near the automatic door device 1 so as to face the wall surface 3 of the automatic door device 1. As shown in Figure 2, the protective fence 10 is composed of a portal frame 11 as a framework, upper and lower panels 20, 21 and upper and lower connecting members 30, 40 attached to the portal frame 11, and a water stop plate 50 detachably attached to the portal frame 11. The protective fence 10 also has an attachment portion (described later) for detachably attaching the water stop plate 50 to the portal frame 11.

[0014] <Gate-type frame> The portal frame 11 is composed of a pair of left and right pillars 12, 12 extending vertically at a predetermined distance apart, and a horizontally extending cross member 13 that is detachably connected between the upper ends of the left and right pillars 12, 12.

[0015] [Prop] The support 12 is formed of a tubular member having a hollow interior space and made of a metal such as aluminum, iron, or stainless steel, with a generally circular cross section. The support 12 is formed with vertical grooves 12a as attachment portions to which the waterstop 50 is detachably attached. The pair of left and right support posts 12, 12 are spaced a predetermined distance apart so that the vertical grooves 12a face each other, and their lower ends are fixed to the floor surface (fixed portion) using fixing means such as brackets or anchor bolts (not shown). The shape and material of the support 12 are not limited to the above examples, and the shape of the support 12 may be, for example, a substantially elliptical or rectangular cross section.

[0016] The vertical groove 12a is formed by removing the pipe wall of the support 12 so as to continue downward from a portion of the edge of the upper end opening 12b of the support 12. The vertical groove 12a extends downward from the edge of the upper end opening 12b of the support 12, and is configured as a vertical groove having an open upper end and a bottomed lower end into which the side end 51a of the waterstop 50 can be inserted and removed.

[0017] [Beam] The cross member 13 is formed by bending both ends of a hollow tubular member made of a metal such as aluminum, iron, or stainless steel, having a substantially circular cross section, in the same direction. At the tip of each end of the cross member 13, a connecting portion 13b1 is provided that is fitted into the tube of each support column 12 through the upper end opening 12b of each support column 12 and is detachably connected. In other words, the cross member 13 is formed in a gate shape (substantially U-shaped) that includes a horizontal portion 13a extending horizontally and vertical portions 13b extending downward from both ends of the horizontal portion 13a, and a connecting portion 13b1 is provided at the tip of each vertical portion 13b.

[0018] The connecting portions 13b1 provided at the tip of each vertical portion 13b of the cross member 13 are removably fitted into the pipe of the support 12 from the upper end openings 12b of the left and right supports 12, 12, thereby making the water stop plate 50 detachable from the upper end openings 12b of the support 12. The shape and material of the cross member 13 are not limited to the above examples, and the cross member 13 may be configured to have, for example, a substantially elliptical cross section or a substantially rectangular cross section.

[0019] <Upper panel> The upper panel 20 is made of, for example, a plate material that is elongated in the left-right direction and has a generally rectangular shape when viewed from the front, with a predetermined thickness, and is fixed to the lower part of the horizontal part 13a and the sides of the left and right vertical parts 13b of the cross member 13. In this case, the lower end surface of the upper panel 20 and the lower end surfaces of the left and right vertical parts 13b of the cross member 13 are positioned on approximately the same plane.

[0020] The upper panel 20 is attached and fixed, for example, at its top end and left and right side end portions to the cross member 13 using fixing means such as brackets or screws (not shown). The upper panel 20 is configured to close the space surrounded by the horizontal portion 13a of the cross member 13, the left and right vertical portions 13b, and the upper end portion 51b of the water stop plate 50, and can prevent people and objects from approaching the wall surface 3 side of the automatic door device 1.

[0021] <Lower panel> Lower panel 21 is made of, for example, a plate material that is elongated in the left-right direction and has a generally rectangular shape when viewed from the front, with a predetermined thickness, and its left and right side edges are attached and fixed to each support pillar 12 using fixing means such as brackets or screws (not shown). Lower panel 21 is placed between upper connecting member 30 and lower connecting member 40 that are connected between the left and right support pillars 12, and is configured to prevent people and objects from approaching the wall surface 3 side of the automatic door system 1.

[0022] The mounting structure of the lower panel 21 is not limited to this configuration, and for example, the lower panel 21 may be mounted so that its side ends are removably insertable into vertical grooves 12a formed in the supports 12. In this case, with the upper connecting member 30 detached from the supports 12, the left and right side ends of the lower panel 21 are fitted into the tubes of the left and right supports 12, 12 through the upper end openings 12b of the left and right supports 12, 12 and the vertical grooves 12a, so that the lower surfaces of the left and right side ends rest on the lower edges of the vertical grooves 12a, thereby blocking the lower portion between the left and right supports 12, 12. The upper connecting member 30 can be mounted and fixed between the supports 12 after the lower panel 21 is positioned.

[0023] <Waterstop> The waterstop 50 is disposed, for example, above the upper connecting member 30 that connects the left and right supports 12. As shown in Fig. 3, the waterstop 50 is disposed with its left and right side end portions 51a housed within the pipes of the left and right supports 12 via the vertical grooves 12a of the left and right supports 12.

[0024] Specifically, the left and right side end portions 51a of the water stop plate 50 are inserted through the upper end openings 12b of each support 12 into the vertical grooves 12a, thereby being accommodated (positioned) within the pipes of each support 12, and are supported by the bottomed lower ends of each vertical groove 12a. That is, each side end 51a of the waterstop 50 is configured to be insertable into and detachable from the vertical groove 12a of each support 12, and is stably attached while being supported by the lower end of the vertical groove 12a. In this state, the upper end surface of the upper end 51b of the waterstop 50 and the upper end opening 12b of the support 12 are positioned on approximately the same horizontal plane.

[0025] 3, the watertight materials 52, 53 and the engaging portions 55, 56 provided on the side end portion 51a of the waterstop 50 are housed in a protected state within the internal space of the support 12. The specific configuration of the waterstop 50, including the watertight materials 52, 53 and the engaging portions 55, 56, will be described later.

[0026] Furthermore, the joint 13b1 of the cross member 13 is configured so that when the cross member 13 is fitted into the pipe of the support 12 through the upper end opening 12b of the support 12 and fitted and connected, the upper end portion of the side end 51a of the waterstop 50 does not interfere with the joint 13b1 of the cross member 13. In other words, the joint 13b1 is configured with a notch that removes, for example, a portion that interferes with the upper end portion of the side end 51a of the waterstop 50 or a portion that interferes with the rib 12c inside the support 12. In the illustrated example, the support 12 has a rib 12c extending vertically inside it to enable positioning of each side end 51a of the water stop plate 50, but this rib 12c may be omitted.

[0027] <Upper connecting material> The upper connecting member 30 is, for example, a long tubular member having a hollow interior space. Specifically, the upper connecting member 30 is made of a metal pipe material such as aluminum, iron, or stainless steel, having a substantially rectangular cross section and including a plate-shaped upper wall 31, a plate-shaped bottom wall 33, and plate-shaped front and rear walls 32 and 33 (not shown) that connect the front and rear edges of the upper wall 31 and the bottom wall 33, respectively.

[0028] This upper connecting member 30 is extended approximately horizontally to the left and right support posts 12 at approximately the center of their height so as to connect each support post 12 together, and functions as a restricting section that restricts people or objects from entering (approaching) the wall surface 3 side of the automatic door device 1. The shape and material of the upper connecting member 30 are not limited to the above examples, and the shape of the upper connecting member 30 may be, for example, a substantially circular or elliptical cross section.

[0029] The left and right edges of the top wall 31 and bottom wall 33 of the upper connecting member 30 are each formed in an arc shape to fit along the circumferential surface (side surface) of the support 12, and with these arc-shaped edges abutting against the left and right supports, and with the edges of the front wall 32 and rear wall (not shown) abutting against the left and right supports, the upper connecting member 30 is connected and fixed to the left and right supports 12 by connecting means such as brackets or screws (not shown), or by fastening means such as welding.

[0030] [Storage section] The upper connecting member 30 is provided with a storage section 35 for storing a fixing member A1, which is made up of mounting hardware (fasteners 60, connectors 70) described below, for installing and fixing the waterstop 50 to the installation surface. The storage section 35 is configured to include a storage recess 36 that forms a storage space (recess) for storing (accommodating) the fixing member A1, and a lid 37 that can be opened and closed to close the upper opening of the storage recess 36.

[0031] The storage recess 36 can be configured, for example, as a box-shaped container (case) that is long in the left-right direction and has a front and rear surface that form the front and rear sides, a left side surface that form the left and right sides, and a bottom surface. This container can be made, for example, from a metal plate or a synthetic resin material, and can be detachably installed in the internal space of the upper connecting member 30 through an opening 31a formed in the top wall 31 of the upper connecting member 30. In this case, the container serving as the storage recess 36 can be installed by placing its bottom surface on the top surface of the bottom wall 33 of the upper connecting member 30.

[0032] The height of the container is set to a height that does not protrude upward from the opening 31a formed in the upper wall 31 of the upper connecting member 30 when the container is stored (contained) in the internal space of the upper connecting member 30. Specifically, the container opening is set to be located at a position that is approximately flush with or slightly lower than the upper surface of the upper wall 31. Preferably, the container opening is set to be located at a position lower than the upper surface of the upper wall 31 so that the upper surface of the lid 37 and the upper surface of the upper wall 31 of the upper connecting member 30 can be flush with each other when the lid 37 is closed.

[0033] In the above embodiment, the container serving as the storage recess 36 is configured to be detachably installed within the upper connecting member 30, but the present invention is not limited to this example. For example, the container may be fixed immovably within the upper connecting member 30. In this case, for example, the container may be inserted into the opening 31a of the upper wall 31 and fixed immovably by a fixing means such as welding or adhesive.

[0034] Furthermore, in the above embodiment, the storage recess 36 is configured as a container, but this is not limiting. The storage recess 36 may be configured as the internal space within the upper connecting member 30 itself. In this case, the space surrounded by the front wall 32, bottom wall 33, and rear wall (not shown) of the upper connecting member 30, and the peripheral surface (side surface) of the support 12 may be used as the storage recess for storing (accommodating) the fixing member A1.

[0035] The lid portion 37 is formed, for example, from a long plate made of metal or synthetic resin, and is formed to cover the opening 31a formed in the top wall 31 of the upper connecting member 30 and the upper opening of the storage recess 36. For example, one end side in the front-to-rear direction (the rear end side in the illustrated example) of the lid portion 37 is rotatably supported by a connecting member 38 such as a hinge at the rear edge of the opening 31a formed in the top wall 31. When the opening 31a in the top wall 31 is closed, the lid portion 37 is locked by a locking member or the like (not shown) to maintain the closed state. Preferably, the lid portion 37 is provided so that the top surface of the lid portion 37 is flush with the top surface of the top wall 31 of the upper connecting member 30 when the lid portion 37 is closed.

[0036] When the protective fence 10 is normally installed, the lower end 51c of the water stop 50 is located above the lid 37, and in this state the lid 37 cannot be opened or closed. This prevents the lid 37 from being accidentally opened and the fixing member A1 from being removed from the storage recess 36, allowing the fixing member A1 to be stored appropriately.

[0037] <Lower connecting material> The lower connecting member 40 is made of, for example, a long tubular member having a hollow interior space. Specifically, the lower connecting member 40 is made of a metal pipe material such as aluminum, iron, or stainless steel that has a substantially rectangular cross section and includes, for example, a plate-shaped upper wall 41, a plate-shaped bottom wall (not shown), and plate-shaped front and rear walls (not shown) that connect the front and rear edges of the upper wall 41 and the bottom wall, respectively.

[0038] This lower connecting member 40 is extended approximately horizontally from the left and right support pillars 12 at a vertically lower position so as to connect each support pillar 12 together, and functions as a restricting section that restricts people or objects from entering (approaching) the wall surface 3 side of the automatic door device 1. The shape and material of the lower connecting member 40 are not limited to the above examples. The shape of the lower connecting member 40 may be, for example, a substantially circular or elliptical cross section.

[0039] The left and right edges of the upper wall 41 and bottom wall (not shown) of the lower connecting member 40 are each formed in an arc shape to fit along the circumferential surface (side surface) of the support 12, and with these arc-shaped edges abutting against the left and right supports, and with the edges of the front wall 42 and rear wall (not shown) abutting against the left and right supports, they are connected and fixed to the left and right supports 12, for example, by connecting means such as brackets or screws (not shown), or by fastening means such as welding.

[0040] [Storage section] The lower connecting member 40 is also provided with a storage section 45 for storing a fixing member A1, which is made up of mounting hardware (fasteners 60, connectors 70) described below, for installing and fixing the waterstop 50 to the installation surface. The storage section 45 is configured to include a storage recess 46 that forms a storage space (recess) for storing (accommodating) the fixing member A1, and a lid 47 for closing the opening of the storage recess 46 in an openable and closable manner.

[0041] The storage recess 46 can be configured, for example, as a box-shaped container (case) that is long in the left-right direction and has a top surface and a bottom surface that form the upper and lower sides, a left side surface and a right side surface that form the left and right sides, and a rear surface that forms the rear. This container can be made, for example, from a metal plate or a synthetic resin material, and can be detachably installed inside the lower connecting member 40 through an opening 42a formed in the front wall 42 of the lower connecting member 40. In this case, the container serving as the storage recess 46 can be installed by placing the bottom surface of the container on the upper surface of the bottom wall (not shown) of the lower connecting member 40.

[0042] The depth of the container is set so that when the container is stored (contained) in the internal space of the lower connecting member 40, it does not protrude from the opening 42a formed in the front wall 42 of the lower connecting member 40. Specifically, the opening of the container is set so as to be approximately flush with the front surface of the front wall 42 or to be located slightly further back (rearward). Preferably, the opening of the container is set so as to be located further back than the front surface of the front wall 42 so that the front surface of the lid 47 and the front surface of the front wall 42 of the lower connecting member 40 can be flush with each other when the lid 47 is closed.

[0043] In the above embodiment, the container serving as the storage recess 46 is configured to be detachably installed within the lower connecting member 40, but the present invention is not limited to this example. For example, the container may be fixed immovably within the lower connecting member 40. In this case, for example, the container may be inserted into the opening 42a of the front wall 42 and fixed immovably by a fixing means such as welding or adhesive.

[0044] Furthermore, in the above embodiment, the storage recess 46 is configured as a container, but this is not limiting. The storage recess 46 may be configured as the internal space within the lower connecting member 40 itself. In this case, the space surrounded by the upper wall 41, bottom wall (not shown), rear wall (not shown) of the lower connecting member 40, and the peripheral surface (side surface) of the support 12 may be used as the storage recess for storing (accommodating) the fixing member A1.

[0045] The lid portion 47 is formed, for example, from a long plate made of metal or synthetic resin, and is formed to cover the opening 42a formed in the front wall 42 of the lower connecting member 40 and the opening of the storage recess 46. For example, one end side (the lower end side in the illustrated example) in the vertical direction of the lid portion 47 is rotatably supported on the lower edge of the opening 42a formed in the front wall 42 via a connecting member 48 such as a hinge. When the opening 42a in the front wall 42 is closed, the lid portion 47 is engaged with an engaging member or the like (not shown) to maintain the closed state. Preferably, the lid portion 47 is provided so that the upper surface of the lid portion 47 is flush with the upper surface of the front wall 42 of the lower connecting member 40 when the lid portion 47 is closed.

[0046] In the above embodiment, the upper connecting member 30 and the lower connecting member 40 are provided with the storage sections 35, 45, respectively, but this is not limiting. For example, a storage section may be provided in only one of the upper connecting member 30 and the lower connecting member 40.

[0047] (Installation of water stop device) Next, we will explain an example of how the water stop device A is installed in the automatic door system 1. Fig. 4 is a schematic front view seen from the outside showing an example of the installed state of the water stop device according to the present invention. Fig. 5 is a schematic side view showing the installed state of the water stop device, and Fig. 6 is a schematic plan view showing the installed state of the water stop device.

[0048] As shown in Figure 4, the water stop device A has one or more water stops 50 (two on the left and right in the illustrated example) installed between left and right support posts X, X (uprights of the automatic door device 1) spaced apart in the width direction, and the water stops 50 block the flow of water that attempts to pass between the support posts X, X.

[0049] This water stop device A has two water stop plates 50, 50 and a fixing member A1 made up of mounting hardware (fasteners 60, connectors 70) and the like for installing and fixing these water stop plates 50, 50 to an installation surface G on the outdoor side.

[0050] <Strut> The pillars X constitute both the left and right sides of the opening of the structure on which the water stop device A is to be installed. In this embodiment, the system is made up of left and right pillars X, X erected in the opening that is opened and closed by the opening and closing door 2 of the automatic door device 1. Each pillar X is formed, for example, from a hard metal material in the shape of a pillar extending upward from the installation surface G. As shown in Figure 5, an upper engaged portion x1 and a lower engaged portion x2 are provided on the opening side surface (visible surface) of each support X, and these upper engaged portion x1 and lower engaged portion x2 are engaged with and attached to upper engaging portion 55 and lower engaging portion 56 provided on water stop plate 50, respectively.

[0051] The upper engaged portion x1 and the lower engaged portion x2 are each formed in the shape of a cylindrical pin made of hard metal material. The upper engaged portion x1 and the lower engaged portion x2 protrude inward (toward the center of the opening) between the left and right columns X, X at the upper and lower sides of the column X, respectively.

[0052] <Waterstop> The waterstops 50 are provided adjacent to each other on the left and right so as to cover the left and right halves of the opening between the supports X, X. These two waterstops 50, 50 are configured symmetrically and are watertightly connected to each other.

[0053] Each waterstop 50 integrally comprises a waterstop body 51 which is approximately rectangular when viewed from the front, a first vertical watertight material 52 which protrudes from one end in the width direction on the downstream side of the waterstop body 51 and continues in an elongated shape in the vertical direction, a second vertical watertight material 53 which protrudes from the side at the other end of the waterstop body 51 and continues in an elongated shape in the vertical direction, a horizontal watertight material 54 which protrudes downward from the waterstop body 51 and continues in an elongated shape in the width direction, and an upper engaging portion 55 and a lower engaging portion 56 which protrude from the left end or right end of the waterstop body 51 toward the corresponding support X.

[0054] The waterstop body 51 is formed into a substantially rectangular plate shape with a predetermined thickness from a hard material such as metal. As shown in Figure 6, the downstream side of the waterstop body 51 is cut out in a concave shape at the portion facing the support X, and the first vertical watertight member 52, the upper engaging portion 55, and the lower engaging portion 56 are provided in this concave portion.

[0055] Furthermore, a locked portion 57 (see FIG. 5) for locking the engaging / disengaging portion 61a of the locking device 60 is provided on the lower portion of the upstream surface of the waterstop body 51. Specifically, a bottomed hole (not shown) that is open on the upstream side is provided on the lower portion of the upstream surface of the waterstop body 51, and a plate-shaped locked portion 57 that stands upward is provided inside this hole. As another example, the locked portion 57 may be arranged so that it is exposed to the outside.

[0056] The first vertical watertight member 52 and the second vertical watertight member 53 (see FIG. 6) are each formed into a continuous, elongated shape in the vertical direction from an elastic material such as rubber or elastomer resin. The first vertical watertight member 52 is pressed against the support X over its entire vertical length, and the second vertical watertight member 53 is pressed against the second vertical watertight member 53 of the adjacent waterstop 50 over its entire vertical length. In addition, a single waterstop 50 installed in an automatic door system has the first vertical watertight member 52 attached to the left and right side end portions 51 a instead of the second vertical watertight member 53. The lateral watertight material 54 (see FIG. 5) is formed in an elongated shape from an elastic material such as rubber or elastomer resin, and is continuous in an elongated shape over substantially the entire length in the left-right direction on the lower end surface of the waterstop body 51. The lateral watertight material 54 is pressed against the installation surface G over the entire length in the left-right direction.

[0057] <Latching device> The fastening device 60 includes, for example, a fastening piece 61 whose one end is fastened to the waterstop body 51 and whose other end is in contact with the installation surface G, and a detachable member 62 that detachably fastens the fastening piece 61 to the installation surface G. The locking piece 61 has two locking / disengaging portions 61a, 61a that are roughly forked in plan view at one end, and a flat fixing portion 61b that is fixed to the installation surface G by overlapping it at the other end.

[0058] The two engaging and disengaging portions 61a, 61a are disposed to correspond to the left and right waterstops 50, 50. Each engaging and disengaging portion 61a is formed in a generally hook shape so as to engage with and disengage from the engaged portion 57 inside the waterstop body 51.

[0059] The fixing portion 61b is formed in a flat plate shape that overlaps the installation surface G, and has a through-hole (not shown) for inserting the detachable member 62 vertically.

[0060] The detachable member 62 is a bolt having a male thread on the tip end side and a knob portion that can be rotated by hand and fixed to the rear end side. The male screw portion of this detachable member 62 passes through the fixing portion 61b of the locking piece 61 and is screwed into a female screw hole g1 provided in the installation surface G and tightened.

[0061] <Connector> The connector 70 is installed diagonally between the top of the waterstop 50 and the installation surface G (see Figure 5), and pulls the top of the waterstop 50 diagonally downward, pressing the lateral watertight material 54 at the lower end of the waterstop 50 against the installation surface G.

[0062] This connecting device 70 includes, for example, a pulling device 71 that is operated to pull the upper part of the water stop plate 50 diagonally downward, a detachable part 72 that is pivoted to the upper end side of the pulling device 71 and is detachably connected to the upper side of the water stop plate 50, and a fastening part 73 that supports the lower end side of the pulling device 71 and is detachably fastened to the installation surface G.

[0063] The pulling tool 71 includes, for example, a substantially cylindrical rotation operation part 71a located toward the center in the longitudinal direction, an upper screw member 71b with a right-hand thread threaded on one end of the rotation operation part 71a, and a lower screw member 71c with a left-hand thread threaded on the other end of the rotation operation part 71a. With this pulling tool 71, rotating the rotation operation part 71a in one direction narrows the gap between the upper screw member 71b and the lower screw member 71c, and rotating the rotation operation part 71a in the opposite direction widens the gap between the upper screw member 71b and the lower screw member 71c. A turnbuckle of known structure can be used for this pulling tool 71.

[0064] A bracket 71b1 is fixed integrally to the upper end of the upper screw member 71b, and a bracket 71c1 is fixed integrally to the lower end of the lower screw member 71c.

[0065] The detachable portion 72 integrally comprises an engaging portion 72a that fits across two adjacent waterstop plates 50, 50 in the width direction, and a pivoting portion 72b that rotatably supports a bracket 71b1 fixed to the upper end side of the upper screw-engaging member 71b.

[0066] The fitting portion 72a has a channel steel shape with an inverted concave vertical cross section that continues in the width direction, and is made of a hard metal material.

[0067] The pivot portion 72b protrudes upstream from the fitting portion 72a, and rotatably supports the upper end of the upper screw member 71b at its tip via a rotation shaft 72c. That is, the upper screw member 71b is supported by the pivot portion 72b so as to rotate around the rotation shaft 72c in the width direction.

[0068] The fastening portion 73 pivotally supports a bracket 71c1 fixed to the lower end side of the lower screw member 71c, and is composed of a support member 73a fixed to the installation surface G, and a detachable member 73b that detachably connects this support member 73a to the installation surface G.

[0069] The support member 73a integrally includes a substantially plate-shaped base 73a1 that overlaps the installation surface G and a pivot portion 73a2 that protrudes upward from the base 73a1. The pivot portion 73a2 rotatably supports a bracket 71c1 on the lower end side of the lower screw member 71c via a horizontal rotation shaft 73c.

[0070] The detachable member 73b has a knob that can be rotated by hand and is fixed to the rear end of a bolt that has a male thread on the tip end, similar to the detachable member 62. The male thread of the detachable member 73b passes downward through the base 73a1 of the support member 73a and is screwed into a female threaded hole g2 provided in the installation surface G.

[0071] (Water stop device installation method (procedure)) Next, a description will be given of an installation method (procedure) for installing the waterproofing device A. Figures 7 and 8 are explanatory diagrams for explaining an installation mode of the waterproofing device according to the present invention. Because the water stop device A is used when the water level rises due to a typhoon, heavy rain, or the like, it is normally stored as an assembled component of the protective fence 10 placed near the automatic door device 1, or housed (stored) within the components of the protective fence 10, as shown in Figure 1. In other words, the water stop plate 50 is stored attached to and assembled on the support post 12 of the protective fence 10, and the fixing members A1 such as the locking device 60 and connecting device 70 are stored housed (stored) in the respective storage sections 35, 45 of the upper connecting member 30 and lower connecting member 40 of the protective fence 10.

[0072] <Step 1> When flooding due to a typhoon, heavy rain, or the like is anticipated, the waterstop 50 and fixing member A1 are removed from the protective fence 10. In this case, first, the cross members 13 of the portal frame 11 are removed from the left and right support posts 12, 12, and the waterstop 50 is pulled upward and removed from the vertical grooves 12a of each support post 12. Thereafter, the lid portion 37 of the upper connecting member 30 is opened, and the fixing member A1 stored (housed) in the storage recess 36 is removed. Also, the lid portion 47 of the lower connecting member 40 is opened, and the fixing member A1 stored (housed) in the storage recess 46 is removed.

[0073] <Step 2> Next, as shown in FIG. 7, the left and right waterstop plates 50, 50 are hung on the left and right supports X, X, respectively, and are set upright on the installation surface G. [Step 2-1] Specifically, first, for one of the left and right waterstop plates 50, the first vertical watertight material 52 (see Figure 6) is pressed against the support X, and the horizontal watertight material 54 is pressed against the installation surface G, so that the upper engaging portion 55 and the lower engaging portion 56 are engaged with the upper engaged portion x1 and the lower engaged portion x2 of the support X, respectively.

[0074] [Step 2-2] Next, in the same manner as for one of the left and right waterstops 50, for the other of the left and right waterstops 50, the first vertical watertight material 52 is pressed against the support X and the horizontal watertight material 54 is pressed against the installation surface G, and further, the second vertical watertight material 53 is pressed against the second vertical watertight material 53 of one of the waterstops 50, and the upper engaging portion 55 and the lower engaging portion 56 are engaged with the upper engaged portion x1 and the lower engaged portion x2 of the support X, respectively.

[0075] <Step 3> Next, as shown in FIG. 8, the left and right waterstop plates 50, 50 are fixed to the installation surface G by the locking members 60 and the connecting members 70. [Step 3-1] Specifically, first, the lower end sides of the left and right water stops 50, 50 are fixed to the installation surface G by the locking device 60. In this case, the engaging and detaching portions 61a, 61a of the locking pieces 61 of the locking device 60 are hooked onto the engaged portions 57, 57 of the left and right water stops 50, 50, respectively, and the fixing portions 61b are fastened to the installation surface G by the detachable members 62.

[0076] [Step 3-2] Next, the upper portions of the left and right waterstops 50, 50 are connected to the installation surface G by the connector 70. First, the fitting portion 72a on the upper end side of the connector 70 is placed over the left and right waterstops 50, 50 from above so as to straddle them from the left and right. Next, the support member 73a is fastened to the installation surface G by the detachable member 73b. In this case, the connector 70 can be tightened by rotating the rotation operating portion 71a of the connector 70. This operation pulls the upper ends of both waterstops 50, 50 diagonally downward toward the upstream side, and the lateral watertight materials 54 at the lower ends of each waterstop 50 are pressed more firmly against the installation surface G.

[0077] The waterstop 50 can be installed and fixed to the installation surface G by the above procedure. With this water stop device A, the center side of each water stop plate 50, 50 can be pressed downward sufficiently, and even if the installation surface G is slightly uneven, the lateral watertight material 54 can be brought into close contact with the installation surface G, preventing water leakage between the water stop plate 50 and the installation surface G.

[0078] Furthermore, when the water stop device A installed on the installation surface G is subsequently removed for storage, it can be stored in the protective fence 10 by following the reverse procedure of the installation procedure described above. The connectors 70 and locking devices 60 are removed from each water stop plate 50 and stored in the storage sections 35, 45 of the upper connecting member 30 and lower connecting member 40 of the protective fence 10, and the water stop plates 50 are attached to the left and right supports 12, 12 of the protective fence 10 to return them to their original state.

[0079] As described above, the protective fence 10 allows the waterstop 50 and the fixing member A1 such as a mounting bracket to be stored in a suitable manner.

[0080] Next, another embodiment of the present invention will be described. Note that since the other embodiment described below is a partial modification of the configuration of the above embodiment, the modified portion will be mainly described, and the same components will be assigned the same reference numerals and redundant description will be omitted.

[0081] (Second embodiment) 9 is a schematic perspective view showing another example of a protective fence according to the present invention. The protective fence 10A shown in the figure is configured so that a storage section for the fixing member A1 is also provided on the support post 12'.

[0082] Specifically, the support 12' is provided with a storage section 100 for storing the fixing member A1, for example, extending downward from approximately the center of the support 12'. This storage section 100 is configured to include a storage recess 101 that forms a storage space (recess) for storing (accommodating) the fixing member A1, and a lid 102 for closing the opening of this storage recess 101 in an openable and closable manner.

[0083] The storage recess 101 can be configured, for example, as a long, vertically extending box-shaped container (case) having an opening. This container can be made of, for example, a metal plate or a synthetic resin material, and is configured to be detachably installed in the internal space of the support 12′ through an opening formed in the peripheral wall of the support 12′, or to be fixedly secured within the support 12′.

[0084] The lid 102 is formed, for example, from a long plate made of metal or synthetic resin, and is formed so as to cover the opening formed in the peripheral wall of the support 12' and the opening of the storage recess 101. For example, one end side in the left-right direction (the right side in the illustrated example) of the lid 102 is rotatably supported on the side edge of the opening formed in the peripheral wall of the support 12' via a connecting member 103 such as a hinge. When the opening in the peripheral wall of the support 12' is closed, the lid 102 is locked by a locking member or the like (not shown) to maintain the closed state. Furthermore, the lid portion 102 is provided so that when the lid portion 102 is closed, the surface of the lid portion 102 and the peripheral wall surface of the support 12' are substantially flush (the same arcuate surface in the illustrated example).

[0085] In the above example, the storage recess 101 is configured as a container, but the internal space within the support 12' itself may be configured as the storage recess without being configured as a container. In this case, for example, a bottom wall may be provided in the internal space of the support 12' at a position lower than an opening formed in the peripheral wall of the support 12', and the space surrounded by this bottom wall and the peripheral surface (side surface) of the support 12' may be configured as the storage recess for storing (accommodating) the fixing member A1.

[0086] Furthermore, in the above example, the storage recess 101 is provided only on one side of the support posts 12' that make up the protective fence 10A, but this storage recess 101 may also be provided on the other side of the support post 12, or it may be configured so that it is provided on both supports 12, 12'. In addition, in the above example, storage sections 35, 45 are also provided in the upper connecting member 30 and the lower connecting member 40 of the protective fence 10A, but the upper connecting member 30 and the lower connecting member 40 may be configured so that the storage section 100 is provided only on the support posts 12, 12' side without providing the storage sections 35, 45.

[0087] In this embodiment as well, the waterstop 50 and the fixing member A1 such as a mounting bracket can be stored conveniently by the protective fence 10A. (Third embodiment) 10 is a schematic perspective view showing another example of a protective fence according to the present invention. The protective fence 10B shown in the figure is configured so that a storage section 200 can be attached externally to a lower connecting member 40.

[0088] Specifically, a storage unit 200, which is, for example, a substantially rectangular parallelepiped (box-shaped) container (case), is detachably disposed on the lower surface of the lower connecting member 40. This storage unit 200 (container) is configured to have, for example, a main body 201 capable of storing the fixing member A1, and a lid 202 for closing an opening formed in the front surface of this main body 201 in an openable and closable manner.

[0089] The main body 201 is configured as a container (case) made of, for example, a metal plate or synthetic resin material with an opening on the front, and has an internal storage space for storing the fixing member A1. The main body 201 can be formed as containers of various sizes that are placed in the spaces between the left and right support columns 12 and the lower connecting member 40.

[0090] Lid 202 is formed, for example, from a long plate made of metal or synthetic resin, and is formed so as to cover the opening of main body 201. This lid 202 is configured such that, for example, one end side in the vertical direction (the lower side in the illustrated example) is rotatably supported via connecting member 203 such as a hinge on the lower edge of an opening formed in the front surface of main body 201, and when the opening of main body 201 is closed, it is locked by a locking member or the like (not shown) to maintain the closed state.

[0091] In addition, an engaging device such as a magnet or hook (not shown) is provided on the upper surface of the storage section 200, and it can be magnetically attracted to the lower surface of the lower connecting material 40 of the protective fence 10B, or can be attached and detached by engaging with the engaging device, etc. The storage section 200 may be configured to be fixedly provided on the lower surface of the lower connecting member 40.

[0092] In this embodiment as well, the waterstop 50 and the fixing member A1 such as a mounting bracket can be stored conveniently by the protective fence 10B. (Fourth embodiment) 11 is a schematic perspective view showing another example of a protective fence according to the present invention. The protective fence 10C shown in the figure is configured so that a cross member 13' is rotatably attached to one of the support posts 12, and a storage section 300 is detachably supported by an upper connecting member 30'.

[0093] Specifically, a connecting part (not shown) is provided at the tip end of one vertical part 13c of the cross member 13', and this connecting part is fitted and connected from the upper end opening of one of the support columns 12 into the tube of the support column 12 so as to be movable up and down and rotatable about the vertical axis. Also, a connecting part 13b1 is provided at the tip end of the other vertical part 13b of the cross member 13', as in the first embodiment described above, which is fitted into the tube of the support column 12 from the upper end opening 12b of the support column 12 and is fitted and connected detachably.

[0094] To remove the waterstop 50 and storage section 300 from the protective fence 10C, the horizontal member 13' is lifted slightly to disengage the connecting portion 13b1 of the other vertical portion 13b from the upper end opening 12b of the support 12, and the horizontal member 13' is rotated around the axis of one vertical portion 13c. A vertical groove 13c1 that can connect with the vertical groove 12a formed in the support 12 is formed at a predetermined position on one vertical portion 13c. For example, when the horizontal member 13' is rotated 90 degrees, the vertical grooves 12a and 13c1 become continuous from top to bottom, and in this state, the waterstop 50 can be pulled out upward.

[0095] The upper connecting member 30' is, for example, composed of a long tubular member made of metal having a hollow internal space, and is provided with an attachment portion 30a' for attaching a storage portion 300 consisting of, for example, a container (case) having an approximately rectangular parallelepiped (box-shaped) shape. This mounting portion 30a' can be configured to have, for example, an insertion hole through which the storage portion 300 is inserted in the vertical direction, and a locking portion (not shown) that locks the upper end portion of the storage portion 300. In other words, the container as the storage portion 300 is configured to be supported by being removably attached to the upper connecting member 30' from above.

[0096] The container serving as the storage unit 300 is configured as, for example, a container (case) made of a metal plate or synthetic resin material with an opening on the top surface, and has an internal storage space for storing the fixing member A1. The storage unit 300 can be formed as containers of various sizes that are placed in the spaces between the left and right support columns 12 and the lower connecting member 40.

[0097] In this fourth embodiment, the lower panel 21 of the protective fence in the above-described embodiment is omitted, and the storage section 300 is positioned so that it protrudes downward below the lower part of the upper connecting member 30'. Therefore, this storage section 300 is configured to close the space below the upper connecting member 30', and can prevent people and objects from approaching the wall surface 3 side of the automatic door system 1.

[0098] In this embodiment as well, the waterstop 50 and the fixing member A1 such as a mounting bracket can be stored conveniently by the protective fence 10C.

[0099] In the above embodiment, an example of a protective fence installed near the automatic door device 1 has been described, but the protective fence that is the subject of the present invention may also be a protective fence installed in a location such as a road or other land. In addition, the storage section provided in the frame of the protective fence may be configured as a drawer-type storage section that can slide relative to the frame.

[0100] The present invention is not limited to the specific configurations described above, and can be modified as appropriate within the scope of the present invention.
