Description

[Technical field]

[0001] The present invention relates to a temporary passageway that is temporarily installed at a site where people gather or in the surrounding area to allow pedestrians, wheelchairs, etc. to pass safely on a temporary basis. [Background technology]

[0002] Conventionally, a known temporary passage of this type comprises a roughly rectangular plate-like body having a connecting protrusion on one of the opposing short sides and a recess on the other side into which the protrusion can be detachably fitted, thereby connecting multiple plate-like bodies sequentially in the longitudinal direction to allow the passage of pedestrians, wheelchairs, etc. (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 62-66904 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, in the case of temporary passageways that are temporarily installed at sites where people gather or in the vicinity thereof, it is necessary to clearly indicate the existence of the temporary passageway itself so that walkers and wheelchairs using the passageway do not stray from the passageway or are not cut in halfway from the outside. In that case, as shown in Figures 21 and 22, it is conceivable to install a number of road cones S, S, ... (so-called color cones: registered trademark) or single-tube barricades (not shown) at a predetermined interval in the passageway direction on both ends of the passageway width of the temporary passageway X, and to connect adjacent road cones S, S or single-tube barricades in the passageway direction using a connecting member such as a cone bar B.

[0005] However, since temporary passageways are merely temporarily installed at sites G where people gather, the passageway width may not be sufficiently secured, and when multiple road cones S, S, ... or single-pipe barricades are installed at a specified interval in the passageway direction on both ends of the passageway width of temporary passageway X, the following problem occurs: The base S1 of each road cone S is a roughly square shape with a sufficient length on each side to prevent it from falling over, but each single-pipe barricade widens in the passageway width direction as it goes downwards, so nearly half of the base S1 or single-pipe barricade will intrude inside the passageway width of temporary passageway X.

[0006] As a result, the width of the passageway between the road cones S, S and the single-tube barricades of the temporary passageway X was just wide enough for wheelchair K to pass through, and when pedestrians were also using the passageway in addition to wheelchair K, they could not pass each other smoothly, so a solution to this problem was urgently needed.

[0007] The present invention has been made in consideration of the above-mentioned points, and its purpose is to provide a temporary passageway that can clearly indicate the existence of the temporary passageway itself without relying on road cones or single-tube barricades, while ensuring the passageway width and allowing smooth passage of wheelchairs and pedestrians.

[0008] In order to achieve the above object, the present invention is premised on a temporary passage having a temporary passage body that is temporarily installed at a site where people gather or in the vicinity thereof to allow safe passage of pedestrians, wheelchairs, etc., on an emergency basis. Furthermore, the temporary passage body is provided with a plurality of temporary devices installed at predetermined intervals in the passage direction of the temporary passage body, and a laying sheet is provided to be laid across the passage direction. Each of the temporary devices is characterized by comprising a plate frame portion extending between both ends of the passage width of the temporary passage body, extension frame portions starting from both ends of each of the plate frame portions and extending on both sides in the passage direction outside the plate frame portions, pole portions provided at the center position in the passage direction of both of the extension frame portions and rising upward from the center position in the passage direction, a connecting member that connects each of the temporary devices adjacent to each other in the passage direction of the temporary passage body, and a locking device provided at the upper end of each of the pole portions to lock the end of the connecting member.

[0009] Each fastener may be provided with a display member for displaying a display for displaying information.

[0010] Furthermore, each of the pole sections may be attached to a central position of both of the extension frame sections in the passage direction via an attachment means.

[0011] The mounting means may further include one of a male threaded portion and a female threaded portion provided at the lower end of each pole portion, and a screw-fitting member provided at a central position in the passage direction of both extension frame portions, the screw-fitting member having the other of the male threaded portion and the female threaded portion that screws into one of the male threaded portion and the female threaded portion.

[0012] In response to this, the mounting means may be provided with an extension portion that is bent approximately 90° from the lower end of each pole portion and extends approximately horizontally along the direction of one of the extension frame portions on both sides of each plate frame portion in the aisle direction, and a folded portion that is folded back approximately horizontally in an approximately U-shape from the tip of the extension portion, a plurality of support portions that are fixed to one of the extension frame portions and support the extension portion of the extension portion at a plurality of points in the aisle direction of each plate frame portion so that it can slide freely in the aisle direction and rotate freely around the axis of the extension portion, and a holding portion that is fixed to one of the extension frame portions and holds the tips of the folded portions of the extension portions inserted when each pole portion is erected.

[0013] The mounting means may also be provided with an extension portion bent approximately 90° from the lower end of each pole portion and extending approximately horizontally along the direction of one of the extension frame portions on both sides of each plate frame portion in the aisle direction; a support portion fixed to one of the extension frame portions and supporting the extension portion so that it can slide freely in the aisle direction of each plate frame portion and can rotate freely about the axis of the extension portion; a biasing means compressed between the rotation support portion and the tip of the extension portion and biasing each of the pole portions toward one of the extension frame portions; and a retaining portion provided at a central position in the aisle direction of both extension frame portions and having a notched hole that holds the lower end of each pole portion inserted from the other side of both extension frame portions by the biasing force of the biasing means when each pole portion is erected. Effect of the Invention

[0014] In short, a plurality of temporary devices are installed at intervals in the passage direction of the temporary passage main body, and extension frame parts are provided on these temporary devices, which extend from both ends of a plate frame part extending between both ends of the passage width of the temporary passage main body as starting points on the outside of the plate frame part on both sides in the passage direction, and pole parts are provided that stand upward from the center position in the passage direction of both extension frame parts.Then, the upper ends of the pole parts of each temporary device that stands upward at both ends of the passage width of the installation sheet laid across the passage direction of the temporary passage main body and are adjacent to each other in the passage direction of the temporary passage main body are connected to each other by a connecting member via a locking device.

[0015] For this reason, by connecting the upper ends of the pole parts of each temporary device that stand upward on the outside of the plate frame part that extends between both ends of the passage width of the temporary passage main body with a connecting member, the passage width of the temporary passage main body is secured without being sacrificed by the pole parts that stand outside the passage width of the temporary passage main body, and the existence of the temporary passage itself is made clear. This ensures the passage width while making the existence of the temporary passage itself clear with the connecting member, allowing wheelchairs and pedestrians to pass each other, and allowing wheelchairs and pedestrians to pass each other smoothly.

[0016] In addition, by providing each fastening device with a display member that displays information, the reason for the temporary passageway that has been temporarily set up becomes clear through the display, making it possible to clearly show to those around the area the reason for the existence of the temporary passageway.

[0017] Furthermore, by attaching each pole section to the central position in the aisle direction of both extension frame sections via mounting means, each pole section can be attached and detached to both extension frame sections via the mounting means, and each temporary device can be stored in a compact state when not in use.

[0018] In addition, the mounting means provides one of a male threaded portion and a female threaded portion at the lower end of each pole section, and a screwing member is provided at the center position of both extension frame sections in the aisle direction to screw into one of the male threaded portion and the female threaded portion at the lower end of each pole section, allowing easy mounting by simply screwing the lower end of each pole section into the screwing members of both extension frame sections.

[0019] In response to this, the mounting means is provided with an extension part that extends from the lower end of each pole part along one of the extension frame parts on both sides of the passage direction of each plate frame part, and a folded part folded back from the tip of the extension part in an approximately U-shape, and a plurality of support parts that are fixed to one of the extension frame parts and support the extension part of the extension part at a plurality of points in the passage direction of each plate frame part, and a holding part that holds the tip of the folded part of the extension part inserted when each pole part is erected. Therefore, each pole part can be held when erected by holding the tip of the folded part inserted from one of the extension frame parts in a state where it is inserted into the holding part, while the extension part can be rotated within each support part in a state where the tip of the folded part is released by sliding it toward the other extension frame part from the holding part, thereby allowing the pole part to be collapsed along the plate frame part and stored. This allows the pole part to be easily converted to an erected state or a stored state simply by inserting or releasing the tip of the folded part of the extension part into or from the holding part of one of the extension frame parts.

[0020] The mounting means includes an extension extending from the lower end of each pole along one of the extension frame parts of each plate frame part, a support part fixed to one of the extension frame parts and supporting the extension, a biasing means for biasing each pole part toward one of the extension frame parts, and a holding part provided at the center of both extension frame parts in the passage direction and having a notched hole for holding the lower end of each pole part inserted from the other side of both extension frame parts by the biasing force of the biasing means when each pole part is erected. Therefore, the lower end of each pole part can be held in the erected state by being inserted from the other side of the holding parts of both extension frame parts through the notched hole by the biasing force of the biasing means, while the lower end of each pole part can be removed from the notched hole of the holding part against the biasing force of the biasing means and the extension part can be rotated in each support part to collapse the pole part along the plate frame part and stored. This allows the pole part to be easily converted between the erected state and the stored state by simply inserting or removing the lower end of each pole part into or from the notched hole of the holding part.

[0022] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0023] Fig. 1 shows a plan view of a temporary passage according to a first embodiment of the present invention, viewed from above, with wheelchairs and pedestrians passing through it. Fig. 2 shows a front view of the temporary passage in Fig. 1, viewed from the front in the passage direction, and Fig. 3 shows a side view of the temporary passage in Fig. 1, viewed from one side in the passage width direction.

[0024] As shown in Figures 1 to 3, reference numeral 1 denotes a temporary passageway, which has a temporary passageway body 10 that is temporarily set up at a site G where people gather to allow pedestrians H, wheelchairs K, etc. to pass safely on a temporary basis.

[0025] The temporary passage body 10 is provided with a plurality of temporary devices 2, 2, ... that are installed at predetermined intervals n (for example, 200 cm) in the passage direction of the temporary passage body 10 (left and right direction in Figs. 1 and 3). The temporary passage body 10 is also provided with a laying sheet 20 that is laid over the entire area in the passage direction. The laying sheet 20 is molded from a rubber material or a synthetic resin material such as polyvinyl chloride or recycled resin, and is set to a thickness of about 3 mm. In this case, the width of the laying sheet 20 is approximately the same as the passage width m of the plate frame portion 21 described later.

[0026] Fig. 4 is a perspective view of the temporary device 2 installed in the temporary passage 1 in Fig. 1, and Fig. 5 shows an enlarged view of the vicinity of the plate frame part on one side in the passage width direction of the temporary device 2 in Fig. 4. Also, Fig. 6 shows an enlarged view of a fastener on one side in the passage width direction of the temporary device 2 in Fig. 4, and Fig. 7 shows an exploded perspective view of one side in the passage width direction of the temporary device 2 in Fig. 4. Furthermore, Fig. 8 shows a perspective view of a state in which a display body is attached to the display member of the fastener on one side in the passage width direction of the temporary device 2 in Fig. 4.

[0027] As shown in Fig. 4 to Fig. 8, each temporary device 2 is provided with a plate frame part 21 extending between both ends of the passage width m (for example, 100 cm) of the temporary passage main body 10, and extension frame parts 22, 22 extending integrally from both ends of the plate frame part 21 toward both sides in the passage direction outside the plate frame part 21. The plate frame part 21 and both extension frame parts 22, 22 are formed by punching out a single flat plate made of metal steel material (for example, general structural rolled steel material), and the surface is treated by zinc plating. The plate frame part 21 and both extension frame parts 22, 22 are set to a thickness of about 1.6 mm to 4.0 mm, so that unevenness caused by the plate frame part 21 when the laying sheet 20 is laid after the temporary passage main body 10 is installed is mitigated as much as possible. In addition, the plate frame portion 21 and both extension frame portions 22, 22 do not have to be formed by punching out from a single flat plate, but may be formed by punching out the plate frame portion and both extension frame portions from flat plates of different thicknesses depending on the installation location, and then welding them together.

[0028] Furthermore, two kinds of round holes 221, 222 with different diameters, large and small, are provided near the extension end of each of the extension frame parts 22, 22. A large-diameter stake or a small-diameter peg (not shown) is driven into at least one of the two kinds of round holes 221, 222 depending on the situation, and thus each temporary device 2 is positioned without shifting at the site G where the temporary passage 1 is to be installed.

[0029] Each temporary device 2 is provided with steel pole parts 23, 23 that stand upward from the center in the passage direction of both extension frame parts 22, 22 that are outside both ends (passage width m of the temporary passage main body 10) of the plate frame part 21. Each pole part 23 is attached to the center in the passage direction of both extension frame parts 22, 22 by attachment means 29. Each pole part 23 is provided with an upper male screw 231 at its upper end and a lower male screw 232 (male screw part) at its lower end.

[0030] Furthermore, each temporary device 2 has a locking device 24 for locking an end of a plastic chain 25 (described later) attached to the upper end of each pole part 23. Each temporary device 2 is equipped with a plastic chain 25 as a connecting member that connects adjacent temporary devices 2, 2 in the passage direction at both ends of the passage width m of the temporary passage main body 10.

[0031] Each fastener 24 has a horizontal portion 241 in the shape of a substantially horizontal plate, and the upper male screw 231 of the pole portion 23 is inserted from below into an insertion hole 242 (shown in FIG. 7) provided in the center of the horizontal portion 241. A nut 26 is screwed into the upper male screw 231 of the pole portion 23, and the fastener 24 is firmly fixed to the nut 26 of the upper male screw 231 by a cap nut 27 with the horizontal portion 241 sandwiched therebetween, with the insertion hole 242 inserted into the upper male screw 231 protruding upward from the nut 26. In this case, each fastener 24 is also formed by punching out from a steel plate having a thickness of approximately 3.5 mm, and the surface is treated by zinc plating.

[0032] A pair of locking pieces 243, 243 facing each other are provided on the horizontal part 241 of each locking tool 24, each of which protrudes upward by about 2 cm from both positions in the passage direction on the plate frame part 21 side and then extends substantially horizontally in a direction facing each other. Also, a pair of left and right notice pieces 244, 244 are provided on the horizontal part 241 of each locking tool 24 as notice members for displaying a notice F indicating information on the installation and guidance of the temporary passage 1. In this case, the notice F includes two laminated panel materials F1, F1 made of transparent laminated tubes, and a sheet F2 indicating information on the installation and guidance of the temporary passage 1, specifically information such as "safe passage", is sandwiched between the two laminated panel materials F1, F1 to be displayed.

[0033] Moreover, each notice piece 244 extends downward from both positions in the passage direction on the opposite side of the plate frame portion 21 of the horizontal portion 241 of each fastener 24, and then is bent in a substantially U-shape so as to open toward the plate frame portion 21. Each notice piece 244 is inserted into a pair of left and right opening holes F3, F3 that open at the upper end of each of the laminated panel materials F1, F1 of the display body F. In this case, when each notice piece 244 is inserted into the left and right opening holes F3, F3 at the upper end of the display body F, it is locked so as to hang down with the lower end of the display body F as a free end.

[0034] The mounting means 29 for mounting the pole portion 23 to both extension frame portions 22, 22 is composed of lower male screws 232 at the lower end of each pole portion 23, and L-shaped pieces 28, 28 as screwing members that are integrally provided at the center of the passage direction of both extension frame portions 22, 22 at both ends of the passage width m direction of the plate frame portion 21 and have a screw hole 281 (female screw portion) at the center of the horizontal portion. Each L-shaped piece 28 is formed in a substantially L-shape that extends upward from the end opposite the plate frame portion 21 at the center of the passage direction of both extension frame portions 22, 22 by about 3 to 4 cm, and then bends toward the plate frame portion 21 and extends horizontally. The lower male screws 232 of the pole portion 23 are screwed into the screw hole 281 at the center of the horizontal portion of each L-shaped piece 28, and the pole portion 23 is held in an upright state upward. In this case, the pole portion 23 in the upright state is set to a height of about 700 mm.

[0035] Next, as an example of temporarily setting up a temporary passage 1 at a site G where people gather, temporary devices 2, 2, ... are set at intervals n in the passage direction of the temporary passage main body 10. Then, the lower male screw 232 of the pole part 23 is screwed into the screw hole 281 of the L-shaped piece 28 in the center of both extension frame parts 22, 22 at both ends in the passage width m direction of the plate frame part 21 of each temporary device 2 to hold the pole part 23 in an upright position upward, and the laying sheet 20 is laid from above the plate frame part 21 of each temporary device 2 across the passage direction of the temporary passage main body 10. Then, the locking device 24 is fastened by the cap nut 27 to the nut 26 screwed into the upper male screw 231 of the pole part 23, sandwiching the horizontal part 241 therebetween. Thereafter, the ends of the plastic chain 25 are engaged with the engaging pieces 243, 243 of each engaging device 24, so that adjacent temporary devices 2, 2 in the passage direction are connected by the plastic chain 25 at both ends of the passage width m of the temporary passage main body 10.

[0036] Therefore, in this embodiment, a plurality of temporary devices 2, 2, ... are installed at intervals in the passage direction of the temporary passage main body 10, and each temporary device 2 is provided with extension frame parts 22, 22 that extend from both ends of the plate frame part 21 extending between both ends of the passage width m of the temporary passage main body 10 as starting points on the outside of the plate frame part 21 on both sides in the passage direction, and a pole part 23 that stands upright from the center position in the passage direction of both extension frame parts 22, 22. The upper ends of the pole parts 23, 23 of each of the temporary devices 2, 2 adjacent to each other in the passage direction of the temporary passage main body 10 that stand upright at both ends of the passage width of the laying sheet 20 laid across the passage direction of the temporary passage main body 10 are connected to each other by a plastic chain 25 via the locking pieces 244, 244 of the locking device 24.

[0037] For this reason, by connecting the upper ends of the pole parts 23 of each temporary device 2 that stand upward outside the plate frame parts 21 extending between both ends of the passage width m of the temporary passage main body 10 with a plastic chain 25, the passage width m of the temporary passage main body 10 is secured without being sacrificed by the pole parts 23 that stand outside the passage width m of the temporary passage main body 10, and the existence of the temporary passage 1 itself is made clear. As a result, the passage width m is secured while the existence of the temporary passage 1 itself is made clear by the plastic chain 25, enabling wheelchairs K and pedestrians H to pass each other, and allowing the wheelchairs K and pedestrians H to pass each other smoothly.

[0038] In addition, each fastening device 24 is provided with display pieces 243, 243 that display display elements F for displaying information, so that the reason for the temporary passage 1 that has been temporarily installed becomes clear through the display elements F, and the reason for the existence of the temporary passage 1 can be clearly indicated to those around.

[0039] Furthermore, since each pole portion 23 is attached to the central position in the aisle direction of both extension frame portions 22, 22 via mounting means 29, each pole portion 23 can be detached from both extension frame portions 22, 22 via the mounting means 29, and each temporary device 1 can be stored in a compact state when not in use.

[0040] In addition, the mounting means 29 is composed of a lower male threaded portion 232 provided at the lower end of each pole portion 23, and an L-shaped piece 28 provided at the central position in the aisle direction of both extension frame portions 22, 22 at both ends of the plate frame portion 21 in the aisle width m direction and having a screw hole 281 that screws into the lower male threaded portion 232 of each pole portion 23, so that mounting can be easily performed by simply screwing the lower male threaded portion 232 of each pole portion 23 into the L-shaped pieces 28 of both extension frame portions 22, 22.

[0041] Furthermore, since the width of the laying sheet 20 is approximately the same as the passage width m of the plate frame portion 21, the step caused by the plate frame portion 21 extending between both ends of the passage width m of the temporary passage main body 10 is eliminated by the laying sheet 20 laid over the entire passage direction of the temporary passage main body 10, allowing wheelchairs K and pedestrians H to pass through safely and smoothly.

[0042] In the first embodiment, the mounting means 29 is composed of the lower male screw portion 232 at the lower end of each pole portion 23 and the L-shaped piece 28 having the screw hole 281 at the center of both extension frame portions 22, 22 in the passage direction, but as shown in Figures 9 and 10, the mounting means 29' may be composed of the lower male screw portion 232 at the lower end of each pole portion 23 and a nut-shaped screw member 32 fixed to the center of both extension frame portions 22, 22 in the passage direction and having a screw hole (female screw portion) whose screw shaft extends vertically. In this case, too, the lower male screw 232 of the pole portion 23 is screwed into the screw hole of the screw member 32 at the center of both extension frame portions 22, 22 in the passage direction, and the pole portion 23 is held in an upright state upward.

[0043] Furthermore, in the first embodiment and modified example, the mounting means 29 is provided with the lower male threaded portion 232 at the lower end of the pole portion 23, and an L-shaped piece 28 or a screwing member 32 having a screw hole 281 at the central position in the passage direction of both extension frame portions 22, 22. However, the mounting means may also be provided with a nut-shaped member provided at the lower end of the pole portion and having a screw hole (female threaded portion) with a screw shaft extending vertically, and a bolt-shaped screwing member protruding at the central position in the passage direction of both extension frame portions and screwed into the screw hole of the nut-shaped member.

[0044] In the first embodiment, the stopper 24 has the fastening paper pieces 243, 243 for fastening the end of the plastic chain 25 at the upper end of each pole part 23, and the notice pieces 243, 243 for displaying the display F are provided on the stopper 24. However, as shown in Fig. 11 and Fig. 12, each temporary device 33 installed at a predetermined interval n in the passage direction of the temporary passage main body 10 is provided with a steel pole part 34 that stands upward from the center position in the passage direction of both extension frame parts 22, 22. Then, a stopper 35 having only a pair of fastening pieces 36, 36 for fastening the end of a connecting member such as a plastic chain 25 may be fixed to the upper end of each pole part 34 by a screw-shaped fastener 37. In this case, the height of the pole part 34 in the standing state is set to about 700 mm.

[0045] Next, a second embodiment of the present invention will be described with reference to the drawings.

[0046] In this embodiment, the structure of the mounting means for mounting each pole section at the center of both extension frame sections in the aisle direction is changed. Note that the structure other than the mounting means is the same as in the above embodiment, so the same parts are given the same reference numerals and detailed explanations are omitted.

[0047] Fig. 13 shows a perspective view of a temporary device according to a second embodiment of the present invention, and Fig. 14 shows an enlarged view of the vicinity of a plate frame part on one side in the passage width direction of the temporary device of Fig. 13.

[0048] That is, in this embodiment, as shown in Figures 13 and 14, each temporary device 4 installed at a predetermined interval n in the passage direction of the temporary passage main body 10 is provided with a steel pole part 41 that stands upward from the center position in the passage direction of both extension frame parts 22, 22. An upper male screw 411 is provided at the upper end of each pole part 41, which is inserted from below into the central insertion hole 242 in the horizontal part 241 of each locking device 24. In this case, the height of the pole part 41 in the standing state is set to about 700 mm.

[0049] Each pole portion 41 is provided with an extension portion 40 consisting of an extension portion 42 bent at approximately 90° from its lower end and extending straight and approximately horizontally along the direction of one of the extension frame portions 22, 22 on both sides of each plate frame portion 21 in the aisle direction, and a folded portion 43 folded back approximately horizontally by approximately 180° into a substantially U-shape from the tip of this extension portion 42. A tip 44 of the folded portion 43 extends linearly from the folded portion 43 toward the other extension frame portion 22 so as to be parallel to the extension portion 42.

[0050] Moreover, two substantially inverted U-shaped support parts 45, 45 are fixedly provided on the plate frame part 21 side of one extension frame part 22, which support the extension part 42 of the extension part 40 at two locations in the passage direction of each plate frame part so that the extension part 42 can slide freely in the passage direction (axial direction of the extension part 42) and can rotate freely around the axis of the extension part 42. Furthermore, one substantially inverted U-shaped holding part 46 is fixedly provided on the opposite plate frame part 21 side of one extension frame part 22, which holds the tip 44 of the folded part 43 of the extension part 40 inserted toward the other extension frame part 22 side when the pole part 41 is erected.

[0051] Furthermore, the mounting means 49 for mounting the pole part 41 to both extension frame parts 22, 22 is composed of the extension part 42 and the folded part 43 of the extension part 40 of the pole part 41, each support part 45 supporting the extension part 42 in one extension frame part 22 so as to be slidable in its axial direction and rotatable about its axis, and a holding part 46 for holding the tip 44 of the folded part 43 in an inserted state. The holding part 46 holds the tip 44 of the folded part 43 in an inserted state when each pole part 41 is erected. In this case, when each pole part 41 rotates the extension part 42 around the axis of each support part 45 in a state in which the extension part 40 is slid relative to each support part 45 and holding part 46 in the axial direction of the extension part 42 to separate the tip 44 of the folded part 43 from the holding part 46, the folded part 43 rotates upward and falls along the plate frame part 21 from the erected state.

[0052] Therefore, in this embodiment, each pole part 41 can be held in an upright state by inserting the tip 44 of the folded part 43 into the holding part 46, while the extension part 40 is slid relative to each support part 45 and the holding part 46 in the axial direction of the extension part 42 to remove the tip 44 of the folded part 43 from the holding part 46, and the extension part 42 is rotated about the axis of each support part 45 to collapse each pole part 41 along the plate frame part 21 and store it. Thus, each pole part 41 can be easily converted into an upright state or a collapsed state (storage state) by simply inserting the tip 44 of the folded part 43 of the extension part 40 into or removing it from the holding part 46 of one extension frame part 22.

[0053] Next, a third embodiment of the present invention will be described with reference to the drawings.

[0054] In this embodiment, the structure of the mounting means for mounting each pole section at the center of both extension frame sections in the aisle direction is changed. Note that the structure other than the mounting means is the same as in the above embodiment, so the same parts are given the same reference numerals and detailed explanations are omitted.

[0055] FIG. 15 is a perspective view of a temporary device according to a third embodiment of the present invention, and FIG. 16 is an enlarged view of the vicinity of a plate frame part on one side in the passage width direction of the temporary device in FIG.

[0056] That is, in this embodiment, as shown in Figures 15 and 16, each temporary device 5 installed at a predetermined interval n in the passage direction of the temporary passage main body 10 is provided with a steel pole part 51 that stands upward from the center position in the passage direction of both extension frame parts 22, 22. A locking device 35 having a pair of locking pieces 36, 36 is fixed to the upper end of each pole part 51. In this case, the height of the pole part 51 in the standing state is set to about 700 mm.

[0057] Each pole portion 51 is provided with an extension portion 52 that is bent approximately 90° from its lower end and extends approximately horizontally and straight along the direction of one of the extension frame portions 22, 22 on both sides in the aisle direction of each plate frame portion 21. In addition, one of the extension frame portions 22 has two support portions 53, 53 fixed thereto that support the extension portion 52 of each pole portion 51 at two locations in the aisle direction of each plate frame portion so that the extension portion 52 can slide freely in the aisle direction (axial direction of the extension portion 52) and can rotate freely around the axis of the extension portion 52.

[0058] An approximately L-shaped piece 56 is integrally provided at the center of the passageway direction of both extension frame parts 22, 22, which extends upward from the end opposite the plate frame part 21 by about 4 to 5 cm and then bends toward the plate frame part 21 and extends horizontally. An approximately U-shaped cutout hole 57 is provided in the horizontal part of the upper end of this L-shaped piece 56, which opens so that the lower end (straight part) of each pole part 51 can be inserted from the other side of both extension frame parts 22, 22. In this case, the center line of the cutout hole 57 in the insertion direction coincides with the axis of the extension part 52 of each pole part 51 in a plan view.

[0059] Further, a nut member 54 is screwed to the tip of the extension portion 52 of each pole portion 51. A compression spring 55 as a biasing means is compressed between the nut member 54 and the support portion 53 on the tip side of the extension portion 52. When each pole portion 51 is erected, it is biased toward one of the extension frame portions 22 by the biasing force of the compression spring 55 between the nut member 54 and the support portion 53 on the tip side of the extension portion 52, and the lower end portion of each pole portion 51 is held in a state in which it is inserted into the notch hole 57 of the L-shaped piece 56 from the other side of both extension frame portions 22, 22. In this case, the L-shaped piece 56 has a function as a holding portion that holds the lower end portion of each pole portion 51 in a state in which it is inserted into the notch hole 57 when each pole portion 51 is erected.

[0060] The mounting means 59 for mounting the pole part 51 to both extension frame parts 22, 22 is composed of the extension part 42 and the folded part 43 of the extension part 40 of the pole part 51, each support part 45 supporting the extension part 42 in one extension frame part 22 so as to be slidable in its axial direction and rotatable about its axis, and a holding part 46 for holding the tip 44 of the folded part 43 in an inserted state. The holding part 46 holds the tip 44 of the folded part 43 in an inserted state when each pole part 41 is erected. In this case, when the extension part 40 of each pole part 41 is slid in the axial direction of the extension part 42 relative to each support part 45 and holding part 46 to separate the tip 44 of the folded part 43 from the holding part 46, the folded part 43 rotates upward and falls along the plate frame part 21 from the erected state.

[0061] Therefore, in this embodiment, the lower end of each pole part 51 can be held in an upright state by being inserted through the L-shaped pieces 56 of both extension frame parts 22, 22 from the other side through the notched holes 57 by the urging force of the compression spring 55. On the other hand, in a state in which the lower end of each pole part 51 is removed from the notched holes 57 of the L-shaped pieces 56 against the urging force of the compression spring 55, the extension parts 52 can be rotated within each support part 53 to collapse the pole part 51 along the plate frame part 21 and store it. Thus, the pole part 51 can be easily converted into an upright state or a stored state by simply inserting the lower end of each pole part 51 into or removing it from the notched holes 57 of the L-shaped pieces 56.

[0062] Next, a fourth embodiment of the present invention will be described with reference to the drawings.

[0063] In this embodiment, the structure of the mounting means for mounting each pole section at the center of both extension frame sections in the aisle direction is changed. Note that the structure other than the mounting means is the same as in the above embodiment, so the same parts are given the same reference numerals and detailed explanations are omitted.

[0064] Fig. 17 is a perspective view of a temporary device according to a fourth embodiment of the present invention with a pole part attached only to one side in the aisle width direction, and Fig. 18 is a perspective view of the temporary device in Fig. 17 with a pole part attached to the other side in the aisle width direction and removed from the one side in the aisle width direction. Also, Fig. 19 is a rear view of the pole part alone as viewed from the other side in the aisle width direction of the temporary device in Fig. 17, and Fig. 20 is an enlarged view of the plate frame part on the other side in the aisle width direction of the temporary device in Fig. 17.

[0065] That is, in this embodiment, as shown in Fig. 17 to Fig. 20, each temporary device 6 installed at a predetermined interval n in the passage direction of the temporary passage main body 10 has a pole part 61 that stands upward from the center position in the passage direction of both extension frame parts 22, 22. Each pole part 61 is made of a colored pole made of synthetic resin that can be colored to be easily noticeable, and is set to a diameter larger than that of a steel pole. In this case, the height of the pole part 61 in the standing state is set to about 700 mm.

[0066] A pair of locking pieces 62, 62 serving as locking devices are provided at the upper end of each pole portion 61. Also, a recess 63 that is recessed in the radial direction over the entire periphery is provided at the lower end of each pole portion 61.

[0067] At the center position of both extension frame parts 22, 22 in the passage direction, an L-shaped piece 64 is integrally provided, which extends upward from the end opposite to the plate frame part 21 by about 2 cm, and then bends toward the plate frame part 21 and extends horizontally. This L-shaped piece 64 is provided with a substantially U-shaped cutout hole 65 that opens toward the plate frame part 21 side. The lower end of each pole part 61 is inserted through the cutout hole 65 between the center position of both extension frame parts 22, 22 in the passage direction and the L-shaped piece 64, and in this state, the upper side surface of the recess 63 is pressed against the horizontal part of the L-shaped piece 64. In this case, the height of the horizontal part of the L-shaped piece 64 is set slightly higher than the height between the lower end surface of each pole part 61 and the upper side surface of the recess 63, so that the lower end of each pole part 61 is securely held by the pressing force when it is inserted into the L-shaped piece 64 through the cutout hole 65.

[0068] The mounting means 69 for mounting the pole portion 61 to both extension frame portions 22, 22 is composed of the recess 63 of the pole portion 61 and an L-shaped piece 64 that presses the upper side surface of the recess 63 against the horizontal portion when the lower end portion of each pole portion 61 is inserted through the notch hole 65. The L-shaped piece 64 holds each pole portion 61 in an upright state by inserting the lower end portion through the notch hole 65 and pressing the upper side surface of the recess 63 of each pole portion 61 against the horizontal portion. In this case, each pole portion 61 can be removed by releasing the lower end portion from the L-shaped piece 64 through the notch hole 65.

[0069] Therefore, in this embodiment, the lower end of each pole portion 61 can be inserted through the L-shaped pieces 64 of both extension frame portions 22, 22 from the plate frame portion 21 side via the notch holes 65 to hold each pole portion 61 in an upright position. On the other hand, the pole portion 61 can be removed and stored by removing the lower end of each pole portion 61 from the notch holes 65 of the L-shaped pieces 64 to the plate frame portion 21 side. Thus, the pole portion 61 can be easily converted between an upright position and a stored position by simply inserting the lower end of each pole portion 61 through or removing it from the notch holes 65 of the L-shaped pieces 64.

[0070] The present invention is not limited to the above-mentioned embodiments and modifications, but includes various other modifications. For example, in the above-mentioned embodiments, the passage width m of the temporary passage body 10 is set to 100 cm, but it goes without saying that it is not limited to this and may be set to a passage width that allows mutual passage. In that case, the length of the plate frame part extending between both ends of the passage width of the temporary passage body is also changed according to the passage width of the temporary passage body.

[0071] In addition, in each of the above-described embodiments and modifications, the height of the pole portions 23, 34, 41, 51, 61 in the upright state is set to about 700 mm, but this is not limited thereto and may be within the range of 600 to 1200 mm.

[0072] In addition, in each of the above-described embodiments and modified examples, the pole portions 23, 34, 41, 51 are made of steel, but this is not limited to this and any material such as hard synthetic resin or aluminum may be used.

[0073] In addition, in each of the above-described embodiments, attention-calling information is displayed by the display F, but it is also possible to display information on guidance, information that serves as a landmark for guidance to places such as smoking areas, and the like.

[0074] Furthermore, in each of the above-described embodiments, a plastic chain 25 is used as a connecting member, but a plastic cone bar or the like that connects adjacent pole portions in the passage direction may also be used as a connecting member.

[0075] Furthermore, in each of the above-described embodiments, the temporary passage 1 (temporary passage main body 10) is installed at the site G where people gather, but the temporary passage may be installed in the vicinity of the site where people gather. [Explanation of symbols]
