At the position, two tubular members 27 are embedded, and these tubular members 27 having a bottom portion 27A are composed of an upper large diameter portion 27B and a lower small diameter portion 27C, and the small diameter portion 27C. Reference numeral 27C is a female threaded portion having a threaded portion formed on the inner peripheral surface. Of the bridge members 21 and 22, the ends 21B and 22B on the floor member 10 side that are parallel to or substantially parallel to the floor surface 10A of the floor member 10 are when the seat plate 4 reaches the fully closed position. , Each of the tubular members 27 is coupled by the coupling tool 28, and these coupling tools 28 are hexagonal in which the male screw portion which is the shaft portion 28A of the coupling tool 28 is screwed into the small diameter portion 27C of the tubular member 27. It is a bolt with a head.

As described above, the coupling tool 28 has a shaft portion 28A which is a male screw portion inserted into the tubular member 27, and the shaft portion 28A is a female screw portion of the tubular member 27. Since the coupling tool 28 is connected to the tubular member 27 by screwing into the small diameter portion 27C, the tubular member 27 is a connecting member to which the coupling tool 28 is connected.

As described above, when the seat plate 4 reaches the fully closed position, the ends 21A and 22A on the seat plate 4 side of the bridging members 21 and 22 arranged on both sides in the thickness direction of the shutter curtain 2 are By being coupled to the reinforcing members 23 and 24 by the couplers 25 and 26, these ends 21A and 22A are coupled to the seat plate 4 by the couplers 25 and 26 and the floor of the bridging members 21 and 22. By connecting the ends 21B and 22B on the member 10 side to the respective tubular members 27 embedded in the floor member 10 by the coupling tool 28, these ends 21B and 22B are connected by the coupling tool 28. Since they are coupled to the floor member 10, these connecting members 21 and 22 are obliquely bridged between the seat plate 4 and the floor member 10 when the seat plate 4 reaches the fully closed position. become. As a result, the strength of the seat plate 4 in which the width direction of the shutter curtain 2 is the length direction is reinforced by the bridging members 21 and 22 on both sides of the shutter curtain 2 in the thickness direction.

Therefore, for example, the seat plate 4 can be prevented from bending and deforming toward the indoor side due to the wind pressure due to the strong wind of the typhoon by the bridging member 22 arranged on the indoor side, and for example, by blowing back the wind. The bending and deformation of the seat plate 4 to the outdoor side can be prevented by the bridging member 21 arranged on the outdoor side. For this reason, the seat plate 4 is prevented from bending and deforming on both sides in the thickness direction of the shutter curtain 2, and this bending deformation also prevents the central portion of the seat plate 4 from rising in the length direction, whereby the seat is prevented from being lifted. It is possible to prevent a large gap from being generated between the plate 4 and the floor surface 10A of the floor member 10.

FIG. 4 shows a state when it is no longer necessary to reinforce the strength of the seat plate 4 by the bridging members 21 and 22 due to the passage of a typhoon or the like. The work of removing the bridging members 21 and 22 is performed by the removal, and then the shutter curtain 2 is opened and closed.

Is closed by the closing member 30.

Therefore, in a normal time when the shutter curtain 2 is opened and closed in the vertical direction and the like, the member 30 can prevent mud, dust, and the like from entering and accumulating inside the tubular member 27.

Further, when the insides of the two tubular members 27 are each closed by the closing member 30, the height position of the upper surface of the head 30A, which is the upper surface of the closing member 30, is the floor. It coincides with or substantially coincides with the height position of the floor surface 10A which is the upper surface of the member 10. Therefore, since the head 30A does not or hardly protrudes from the floor surface 10A, the floor surface 10A is in the same state as the original floor surface or substantially the same state, and therefore, the floor surface 10A. A person or the like passing through the above-mentioned doorway having the lower surface can pass through as usual without paying special attention to the closing member 30.

Further, as shown in FIG. 4, the head 30A, which is the top of the closing member 30, is provided with an operation unit 30C used for taking out the closing member 30 from the inside of the tubular member 27.

It is applied to the seat plate 43 including the elevating body 42 arranged so as to be able to move up and down in the vertical direction, and the seat plate holding tool 90 is embedded inside the floor member 10. It is composed of a tubular member 91 and two seat plate pressing members 92 whose lower portion is inserted inside the tubular member 91 when the seat plate 43 has reached the fully closed position. It has become. The positions where the two tubular members 91 are embedded inside the floor member 10 are the locations on both sides of the shutter curtain 2 in the thickness direction, and the seat plate 43 when the fully closed position is reached. The two seat plate pressing members 92, which are within the range of the lower surface of the elevating body 42 and whose lower portion is inserted into the floor member 10 by inserting the lower portion into the inside of each tubular member 91, are fully closed. Of the seat plates 4 that have reached the position, the elevating body 42 is vertically penetrated and arranged.

Therefore, in this embodiment, in order to allow the two seat plate pressing members 82 to vertically penetrate the elevating body 42 of the seat plate 43 when the fully closed position is reached, the thickness of the shutter curtain 2 in the elevating body 42 is thick. At two locations in the vertical direction, the two pipe members 85 also used in the embodiment of FIG. 13 are arranged so that the axial direction is in the vertical direction, and the heights of the upper and lower surfaces of these pipe members 85 are high. The position coincides with or substantially coincides with the height position of the upper and lower surfaces of the elevating body 42.

Each of the tubular members 91 is provided under the bottom portion 91A, the upper large-diameter portion 91B, and the large-diameter portion 91B, as in the case of the tubular members 27, 37, 61, 81 of the conventional embodiments.

The internal size of the large-diameter portion 91B of the tubular member 91 corresponds to the size of the head 92B of the seat plate pressing member 92, and the total length of the inside of the tubular member 91 in the vertical direction. Is the same as or larger than the total length of the seat plate holding member 92 in the vertical direction.

In this embodiment, the dimensions of the shutter curtain 2 in the thickness direction of the seat plate main body 41 of the seat plate 43 and the elevating body 42 are the same or substantially the same, so that the lower surface of the seat plate main body 41 has an elevating body. At a position corresponding to the arrangement position of the two pipe members 85 in 42, two holes 41F for communicating the internal space of the seat plate main body 41 with the external space below the seat plate main body 41 are formed. There is. Similar to the state shown in FIG. 16, when the seat plate 43 is located above the fully closed position and the vertical distance between the seat plate main body 41 and the elevating body 42 is large, these As can be seen from FIG. 15, after the upper portion of the seat plate pressing member 92 having an oblique posture with respect to the vertical direction is once inserted into the hole 41F, the male screw portion of the seat plate pressing member 92 returned to the vertical posture. The shaft portion 92A is inserted into the pipe member 85 from above, and the shutter curtain 2 is lowered to the fully closed position. It is screwed into the small diameter portion 91C which is the female screw portion. Then, as shown in FIG. 15, the lower surface of the head 92B of the seat plate pressing member 92 is the horizontal or substantially lower surface of the elevating body 42 for the lowering work of the seat plate pressing member 92 performed by this screwing and rotation operation. Continue until it comes into contact with the upper surface, which is a horizontal surface, or until it faces this upper surface with a slight gap.

Therefore, the seat plate holding member 92 in this embodiment extends to the elevating body 42 when the seat plate 43 reaches the fully closed position, but does not extend to the seat plate main body 41 in the vertical direction. have.

In this embodiment, the elevating body 42 of the seat plate 43 that has reached the fully closed position bends and deforms to the indoor side or the outdoor side in the thickness direction of the shutter curtain 2 due to the wind pressure due to the strong wind of the typhoon. Of the total length of the plate pressing member 92 in the vertical direction, it is prevented by the upper portion inserted through the pipe member 85. Further, at this time, the lifting of the elevating body 42 is prevented by the upper surface of the elevating body 42 coming into contact with the lower surface of the head 92B of the seat plate pressing member 92.

Further, when it is no longer necessary to prevent the elevating body 42 of the seat plate 43 from bending and deforming in the thickness direction of the shutter curtain 2 due to the passage of a typhoon or the like, the seat plate 43 is raised by raising the shutter curtain 2. Of these, after raising the seat plate main body 41 a little, each seat plate holding member 92 is pulled out from the tubular member 91 and further from the pipe member 85, and as shown in FIG. 16, the shutter curtain. 2 is made openable and closable in the vertical direction, and the entire length direction of each seat plate pressing member 92 is inserted into the tubular member 91. As a result, the seat plate pressing member 92 can be used as it is as a closing member for closing the inside of the tubular member 91, and the seat plate pressing member 92 can also be used.

Further, also in this embodiment, when the inside of the tubular member 91 is closed by the seat plate pressing member 92, the height position of the upper surface of the head 92B, which is the top of the seat plate pressing member 92, is the upper surface of the floor member 10. It coincides with or substantially coincides with the height position of a certain floor surface 10A. Further, since the groove 93 which is the operation portion 92C described above is formed on the upper surface of the head 92B, the seat plate holding member 92 which is a closing member for closing the inside of the tubular member 91 is provided. The work for taking out from the inside of the tubular member 91 can be easily and quickly performed by engaging a tool such as an electric screwdriver with the groove 93.

Also in this embodiment, the operation unit 92C may not be the groove 93, but the operation unit 92C may be the grip member 31 of FIG. 4 capable of rotating the seat plate pressing member 92.

Further, in this embodiment, as shown in FIG. 16, on the upper and lower ends of the pipe member 85 from which the seat plate holding member 92 is removed, the hard synthetic resin or the like shown in the embodiment of FIG. The shaft portion 89B of the closing member 89 with the lid portion 89A formed in the above is press-fitted, and the upper and lower ends thereof are closed by the closing member 89.

According to this embodiment, the length dimension of the tubular member 91 and the seat plate pressing member 92 in the vertical direction can be made shorter than that of the cylindrical member 81 and the seat plate pressing member 82 used in the embodiment of FIG. You can get the benefits.

In this embodiment, since the dimensions of the shutter curtain 2 of the seat plate 43 and the elevating body 42 in the thickness direction are the same or substantially the same, the lower surface of the seat plate body 41 is described above. Although the hole 41F is provided, when the dimension in the thickness direction of the shutter curtain 2 for the elevating body 42 is larger than the dimension in the thickness direction of the shutter curtain 2 for the seat plate main body 41, the lower surface of the seat plate main body 41 is provided. It is not necessary to provide the hole 41F in the hole 41F.

The seat plate presser 100 shown in FIG. 17 also has the seat plate main body 41 and the seat plate main body 41 in the same manner as the seat plate pressers 40, 80, 90 shown in FIGS. 7, 13 and 15. The lower side is applied to the seat plate 43 including the elevating body 42 arranged so as to be vertically movable with respect to the seat plate main body 41, and the seat plate presser 100 is applied to the floor. The two tubular members 101 embedded inside the member 10 and the two seats whose lower portions are inserted inside the tubular members 101 when the seat plate 43 reaches the fully closed position. It is composed of a plate pressing member 102. The positions where the two tubular members 101 are embedded inside the floor member 10 are the positions on both sides of the shutter curtain 2 in the thickness direction, and the seat plates in the seat plate 43 reaching the fully closed position. The lower part of each seat plate holding member 102, which is a position shifted from the main body 41 and the elevating body 42 in the thickness direction of the shutter curtain 2 and is a circular solid or hollow rod-shaped member in a plan view, has a cylindrical shape. By being inserted into the inside of the member 101, the lower portion of these seat plate pressing members 102 is inserted into the inside of the floor member 10.

As shown in FIG. 17, each of the tubular members 101 has a bottom portion 101A and a large diameter portion 101B at the top, similarly to the tubular members 27, 37, 61, 81, 91 of the previous embodiments. And the small diameter portion 101C provided on the lower side of the large diameter portion 101B, but the small diameter portion 101C is not a female threaded portion. When the seat plate 43 reaches the fully closed position, the lower portion of each seat plate holding member 102 is inserted into the small diameter portion 101C of the tubular member 101, whereby the lower portion of the seat plate 43 is vertically oriented from the tubular member 101. These seat plate pressing members 102 having a large length dimension stand on their own with the lower portion inserted inside the floor member 10. Further, the seat plate pressing member 102 at this time is in contact with both the seat plate main body 41 and the elevating body 42 of the seat plate 43 in the thickness direction of the shutter curtain 2 or faces each other with a slight gap. Further, the upper end of the seat plate holding member 102 reaches the same height position as the upper surface 41G of the seat plate main body 41 or a height position exceeding the upper surface 41G.

Therefore, the seat plate main body 41 and the elevating body 42 of the seat plate 43 that have reached the fully closed position bend and deform toward the indoor side or the outdoor side in the thickness direction of the shutter curtain 2 due to the wind pressure due to the strong wind of the typhoon. Is prevented by the upper part of the total length of the seat plate holding member 102 in the vertical direction except the lower part inserted into the small diameter portion 101C of the tubular member 101.

Further, when it is no longer necessary to prevent the seat plate main body 41 and the elevating body 42 of the seat plate 43 from bending and deforming in the thickness direction of the shutter curtain 2 due to the passage of a typhoon or the like, it is shown in FIG. As shown above, each seat plate pressing member 102 is pulled out from the inside of the tubular member 101, and the inside of each of the tubular member 101 from which the seat plate holding member 102 is pulled out is closed by the closing member 103. Similar to the closing member 30 of FIG. 4, the closing member 103 is made of, for example, a hard synthetic resin, and has a head portion 103A provided with a shaft portion 103B, and has a shaft portion. When the 103B is press-fitted into the small diameter portion 101C of the tubular member 101, the inside of the tubular member 101 is closed by the closing member 103. As a result, the member 103 can prevent mud, dust, and the like from entering and accumulating inside the tubular member 101.

Further, when the inside of the tubular member 101 is closed by the closing member 103, the height position of the upper surface of the head 103A which is the upper surface of the closing member 103 is the height position of the floor surface 10A which is the upper surface of the floor member 10. It is or almost the same as the height position. Therefore, the head 103A does not or hardly protrudes from the floor surface 10A, and the floor surface 10A is in the same state as the original floor surface or in substantially the same state, so that the floor surface 10A is in the same state or substantially the same state. A person or the like passing through the above-mentioned doorway on the lower surface can pass through as usual without paying special attention to the closing member 30.

Further, as shown in FIG. 18, the head 103A, which is the top of the closing member 103, is provided with an operation unit 103C used for taking out the closing member 103 from the inside of the tubular member 101. There is. Similar to the operation unit 30C of FIG. 4, the operation unit 103C is located on both ends of a semicircular main body formed of a hard metal wire on opposite sides of the head 103A having a circular shape in a plan view. It is a pinching member 104 provided with a rotation center shaft portion inserted into holes formed at two locations, and can be freely tilted with respect to the head 103A around these rotation center shaft portions. The closing member 103 can be taken out from the inside of the tubular member 101 by picking the picking member 104 after the picking member 104 is erected as shown by the two-dot chain line in FIG.

Therefore, even if the inside of the two tubular members 101 shown in FIG. 18 is closed by the closing member 103 in the normal time when the typhoon does not arrive, the closing member 103 is tubular when the typhoon arrives. By using the picking member 104, the work for taking out from the inside of the member 101 can be easily and quickly performed.

The seat plate presser 100 of this embodiment shown in FIG. 17 can also be applied to the seat plate 4 shown in FIG. 3 and the like.

The seat plate presser 110 shown in FIG. 19 also has the seat plate main body 41 and this seat in the same manner as the seat plate pressers 40, 80, 90, 100 shown in FIGS. 7, 13, 15, and 17. It is applied to the seat plate 43 configured including the elevating body 42 which is vertically arranged to be able to move up and down with respect to the seat plate main body 41 on the lower side of the plate main body 41. The lower portion of the 110 is inserted into the two tubular members 111 embedded inside the floor member 10 and the inside of the tubular members 111 when the seat plate 43 reaches the fully closed position. It is composed of two seat plate pressing members 112. The positions where the two tubular members 111 are embedded inside the floor member 10 are the locations on both sides of the shutter curtain 2 in the thickness direction, and the seat plate 43 when it reaches the fully closed position. The positions of the shutter curtain 2 are offset from both the seat plate main body 41 and the elevating body 42 in the thickness direction, and the lower portion of each seat plate pressing member 112 is inserted into the tubular member 111. The lower portion of the seat plate holding member 112 is inserted inside the floor member 10.

The vertical length dimension inside the tubular member 111 is the same as or substantially the same as the vertical length dimension of the seat plate holding member 112, and in FIG. 20, these tubular members 111 and the seat are seated. A perspective view of the plate holding member 112 is shown. As shown in FIG. 20, the tubular member 111 has the same outer diameter dimension continuous over the entire length in the vertical direction and has a bottom portion 111A, and has an opening at the upper end. Below the 111B, a wall portion 111C protruding inward of the tubular member 111 is provided. The upper end of the wall portion 111C is a stepped portion 111D, and the inside of the wall portion 111C is a circular hole portion 111E in a plan view in which the opening portion 111B having dimensions in the vertical direction also has a small diameter. The hole 111E has a large vertical dimension from the step 111D to the bottom 111A. Further, the wall portion 111C is formed with two groove portions 111F having a vertical direction extending from the step portion 111D to the bottom portion 111A at two locations on opposite sides in a plan view.

The seat plate pressing member 112 is provided at the main body 112A having a diameter corresponding to the hole portion 111E of the tubular member 111 and being a circular solid or hollow rod-shaped portion in a plan view, and at the upper end portion of the main body 112A. It is composed of a circular head 112B in a plan view, and the diameter dimension and the vertical dimension of the head 112B which is the top of the seat plate holding member 112 are the opening 111B at the upper end of the tubular member 111. Corresponds to diameter dimensions and vertical dimensions. Further, the main body 112A is formed with a protrusion 112D protruding in the outer diameter direction of the main body 112A at a position slightly above the lower surface 112C of the main body 112A, and the protrusions 112D are 2 opposite to each other in a plan view. It is provided in two places.

Of the seat plate holding member 112, the head 112B is formed with an operation portion 112E, and the operation portion 112E is formed in a rectangular hole portion 112F in a plan view formed on the upper surface of the head 112B with a depth. It is a finger hook portion 113 protruding in the horizontal direction. Since the vertical thickness dimension of the finger hook portion 113 is smaller than the depth of the hole portion 112F having the horizontal width dimension extending to the lower part of the finger hook portion 113, the entire seat plate holding member 112 has a tubular shape. By being inserted inside the member 111, even when the entire head 112B of the seat plate holding member 112 is inserted inside the opening 111B of the tubular member 111, the finger inserted from the hole 112F can be inserted. By hanging on the lower surface of the finger hook portion 113, the seat plate holding member 112 can be taken out from the inside of the tubular member 111.

As shown in FIG. 19, when the seat plate 43 has reached the fully closed position, the lower portion of the main body 112A of each seat plate pressing member 112 has a hole 111E from the opening 111B of the tubular member 111. Since each protrusion 112D provided on the seat plate pressing member 112 is displaced from the groove portion 111F of the tubular member 111, each protrusion 112D is inserted into the tubular member 111. It is placed on the step portion 111D. As a result, each seat plate pressing member 112 becomes self-supporting with the lower portion of the main body 112A inserted into the hole portion 111E of the tubular member 111.

Further, at this time, the lower surface of the head 112B of the seat plate pressing member 112 reaches the same height position as the upper surface of the seat plate main body 41 of the seat plate 43 or a high position beyond the upper surface thereof. The seat plate holding member 112 of this embodiment has a vertical length extending to the seat plate main body 41 when the seat plate 43 reaches the fully closed position. Further, at this time, as shown in FIG. 19, the main body 112A of the seat plate pressing member 112 touches or slightly touches both the seat plate main body 41 and the elevating body 42 in the thickness direction of the shutter curtain 2. We are facing each other with a gap.

Therefore, the seat plate main body 41 and the elevating body 42 of the seat plate 43 that have reached the fully closed position bend and deform toward the indoor side or the outdoor side in the thickness direction of the shutter curtain 2 due to the wind pressure due to the strong wind of the typhoon. Is prevented by the upper portion of the total length of the main body 112A of the seat plate pressing member 112 in the vertical direction except the lower portion inserted into the hole portion 111E of the tubular member 111.

Further, when it is no longer necessary to prevent the seat plate main body 41 and the elevating body 42 of the seat plate 43 from bending and deforming in the thickness direction of the shutter curtain 2 due to the passage of a typhoon or the like, the respective seat plates are used. The pressing member 112 is taken out from the inside of the tubular member 111. After that, as can be seen from FIG. 21, by rotating the taken-out seat plate pressing member 112 around the vertical axis, the position of the protrusion 112D of the seat plate pressing member 112 is set to the tubular member 111. The work of inserting the seat plate pressing member 112 into the inside of each cylindrical member 111 from which the seat plate pressing member 112 is pulled out while matching the position of the groove portion 111F of the above and then inserting the protrusion 112D into the groove portion 111F. By this work, the inside of the tubular member 111 is closed by the entire seat plate pressing member 112. As a result, the seat plate pressing member 112, which is entirely inserted into the tubular member 111 in the vertical direction, is used as it is as a closing member for closing the inside of the tubular member 111. It can be used for both purposes.

Also in this embodiment, when the inside of the tubular member 111 is closed by the seat plate pressing member 112, the height position of the upper surface of the head 112B which is the top of the seat plate pressing member 112 is the floor which is the upper surface of the floor member 10. It coincides with or substantially coincides with the height position of the surface 10A. Further, since the finger hook portion 113 which is the operation portion 112E described above is provided on the upper surface of the head 112B, the seat plate holding member which is a closing member for closing the inside of the tubular member 111 is provided. The work for taking out the 112 from the inside of the tubular member 111 can be easily and quickly performed by the finger hook portion 113 which is the operation portion 112E.
