Description

[Technical Field]

[0001] The present invention particularly relates to road closure signs and other signs that are placed across roads to stop vehicles from passing through the roads. [Background technology]

[0002] Conventionally, when an expressway is closed to traffic, a sheet-like road closure curtain 1 as shown in FIG. 7 is installed across the road at the boundary between an ordinary road and the entrance to the expressway.

[0003] When not in use, the road closure curtain 1 is folded and stored in, for example, a road closure curtain storage box 2 installed near an entrance, as shown in Figure 8. When the expressway is closed to traffic, the road closure curtain 1 is taken out of the road closure storage box 2 and both ends of the curtain 1 are attached to posts installed on both sides of the road via ropes 3, blocking the road and preventing cars from entering.

[0004] The traffic stop curtain 1 is foldable, which has the advantage of making it easy to store. Summary of the Invention [Problem to be solved by the invention]

[0005] However, in order to ensure visibility, the above-mentioned road stop curtain 1 is provided with a reflective sheet or the like on the surface of which characters such as "Road No Entry" are printed, etc., and is folded when stored. As shown in Figure 9, the folded reflective sheet portion 4 of the reflective sheet 3 peels off, making it impossible to distinguish the characters, and there are problems with durability.

[0006] The present invention is intended to eliminate the above drawbacks. [Means for solving the problem]

[0007] The folding signboard of the present invention is characterized by comprising a plurality of plate-shaped signboard elements arranged in parallel in the longitudinal direction (horizontal direction), a connecting portion that foldably connects each adjacent signboard element, and a reflective sheet element provided on the surface of the signboard element.

[0008] In addition, the foldable signboard of the present invention is characterized by comprising a plurality of plate-shaped signboard elements arranged in parallel in the longitudinal direction (horizontal direction), a connecting portion that foldably connects a portion of each adjacent signboard element, a connecting means that connects adjacent signboard elements other than a portion of each adjacent signboard element, and a reflective sheet element attached to the signboard element.

[0009] The reflecting sheet element is characterized in that it is not provided across adjacent signboard elements.

[0010] The width of each signboard element in the lateral direction and the thickness of each folded signboard element are smaller than the size of the storage box in which they are stored.

[0011] The signboard element is also characterized in that when all the adjacent signboard elements are opened, the overall length in the longitudinal direction is 2000 mm to 6000 mm, and the length in the lateral direction of each signboard element is 100 mm to 450 mm.

[0012] The signboard element may be provided with one or more openings, and the reflecting sheet element provided on the signboard element having the openings may have openings at corresponding portions. [Effects of the Invention]

[0013] According to this invention, the device is foldable, so it can be stored compactly and is easy to set up.

[0014] It also reduces damage to the reflective sheet and allows the signboard to be maintained for a long period of time.

[0015] In addition, the storage box for conventional road closure curtains can be used to store the foldable sign board.

[0016] Furthermore, since an opening is provided, the wind load during installation can be reduced. [Brief explanation of the drawings]

[0018] An embodiment of the present invention will be described below with reference to the drawings. [Example]

[0019] (1. Overall explanation of the sign board)

[0020] As shown in Figures 1 to 5, the folding signboard 5 of the present invention comprises a plurality of plate-shaped signboard elements 6 arranged in parallel in the longitudinal direction (horizontal direction) on the same plane, openings 7 such as through slits provided in the signboard elements 6, connecting portions 8 such as hinges provided on corresponding sides of each adjacent signboard element 6 to connect the adjacent signboard elements 6 in a foldable manner, and light-reflecting reflective sheet elements 9 with letters 9a, figures 9b, etc. printed on their surfaces and attached by adhesive or the like to each of the signboard elements 6.

[0021] The entirety of the signboard elements 6 constitutes one signboard.

[0022] Furthermore, the plurality of reflective sheet elements 9 form one or more road signs or the like, such as road no entry letters 9a or figures 9b.

[0023] The reflective sheet made up of the plurality of reflective sheet elements 9 may be provided over the entire surface of the signboard, or may be provided over a portion of the surface of the signboard.

[0024] The folding sign 5 is made of aluminum and has an overall length of 2000 mm to 6000 mm in the longitudinal direction, taking into account the width of the road, and a thickness of 1.0 to 2.0 mm, with a standard length of 3500 mm, for example.

[0025] Furthermore, the number of divisions into which the folding sign 5 is divided to create sign board elements 6 is determined by the horizontal length of each sign board element and the thickness when the entire sign board is folded, so that it can be stored in a storage box 2 that previously contained a road stop curtain 1, for example.

[0026] (1.1. Description of signboard element 6)

[0027] For example, since the typical size of a storage box 2 (compact) that has conventionally housed road stop curtains 1 is, for example, 170 mm (width) × 950 mm (height) × 200 mm (depth), the width direction length of each sign plate element 6 is preferably, for example, 100 mm or more and 160 mm or less, although it is not limited to these values.

[0028] The thickness of the folding sign when folded is preferably 110 mm to 150 mm, although it is not limited to this value.

[0029] For example, when adjacent signboard elements 6 are folded with a thickness of 1 mm, the thickness is, for example, 11 mm, taking into account the thickness of the hinge portion, so that the thickness of each folded element is approximately 5.5 mm (note that this thickness will vary depending on the design).

[0030] Therefore, for example, if a 3500 mm signboard 5 is divided so that the horizontal length of the signboard element 6 is approximately 100 mm, the number of divisions will be 35, and the thickness when the whole is folded will be 35 (sheets) x 5.5 mm, which is approximately 193 mm, and it can be stored in the storage box 2.

[0031] Furthermore, for example, if a 3500 mm signboard 5 is divided so that the horizontal length of the signboard element 6 is approximately 145 mm, the number of divisions will be 24, and the thickness when the whole is folded will be 24 (sheets) x 5.5 mm, which is 132 mm, and it can be stored in the storage box 2.

[0032] Furthermore, for example, if a 3500 mm sign is divided so that the horizontal length of the signboard element 6 is approximately 160 mm, the number of divisions will be 22, and the thickness when folded as a whole will be 22 (sheets) x 5.5 mm, or 121 mm, and it can be stored in the storage box 2.

[0033] Note that these are just examples.

[0034] (1.2. Explanation of opening 7)

[0035] The openings 7 may be provided in all the signboard elements 6 or in some of the signboard elements 6.

[0036] Furthermore, the signboard element 6 may have one or more openings 7.

[0037] The opening 7 can reduce the wind load that the signboard 5 receives.

[0038] Depending on the wind load conditions, it may not be necessary to provide openings 7 in all of the signboard elements 6.

[0039] (1.3. Description of connecting portion 8)

[0040] The connecting portion 8 is not particularly limited as long as it allows adjacent signboard elements 6, 6 to be folded until they overlap, and may be, for example, a hinge as shown in FIG.

[0041] Furthermore, by rotating the folding direction of adjacent sign board elements 6, 6 in only one direction and alternately reversing the folding direction of each adjacent sign board element 6, 6, the sign board 5 can be folded in an accordion-like manner, making folding easier.

[0042] (1.4. Explanation of divided parts of sign board 5)

[0043] In addition to all of the signboard elements 6 constituting the signboard 5 being connected by the above-mentioned foldable connecting portions 8, some adjacent signboard elements 6 may not be connected by the above-mentioned foldable connecting portions 8, but rather, for example, as shown in Figure 6, the signboard 5 may be divided into divided portions 5a, 5b, and 5c, and when stored, each of the divided portions 5a, 5b, and 5c may be folded and stored in the storage box 2, and when in use, each of the divided portions 5a, 5b, and 5c may be unfolded and adjacent divided portions may be connected to each other by connecting means such as bolts.

[0044] (1.5. Description of Reflective Sheet Element 9)

[0045] Each of the reflection sheet elements 9 is provided on a corresponding one of the signboard elements 6, and is configured so as not to be provided across adjacent signboard elements 6, 6.

[0046] That is, the reflecting sheet element 9 is not attached to the connecting portion 8 such as a hinge.

[0047] With this configuration, the reflective sheet element 9 does not bend even when the folding signboard 5 is folded, so that the reflective sheet portion 4 can be prevented from peeling off from the signboard 5.

[0048] The reflecting sheet element 9 has an opening formed in a portion corresponding to the opening 7 of the signboard element 6.

[0049] (2. Instructions on how to use the folding sign board)

[0050] For example, a folded sign board 5 stored in a road stop curtain storage box 2 or the like installed near the entrance to a highway is taken out, and each adjacent sign board element 6 is unfolded and placed at the entrance to the highway or the like so as to block the road (in a direction perpendicular to the road), and both ends of the sign board 5 are fixed to, for example, supports or the like installed on both sides of the road.

[0051] In addition, if the road width is longer than the signboard 5, for example, one end of a rope or chain etc. can be fixed to each end of the signboard 5, and the other end of the chain etc. can be fixed to the above-mentioned support etc.

[0052] When storing the sign board 5, it is removed from the support pole, and adjacent sign board elements 6 are folded in an accordion-like manner so that they are inverted relative to each other, and the folded sign board 5 is stored in the storage plate 2.

[0053] (3. Effects of this invention)

[0054] According to this invention, the sign board can be folded and stored compactly in a storage box, making it easy to install.

[0055] In addition, the storage plate can be stored using a conventional storage box for road curtain panels.

[0056] Furthermore, since the reflective sheet portion is not provided across adjacent refracting signboard elements, it will not bend when stored, and therefore the reflective sheet will not peel off from the signboard, improving durability.

[0057] Furthermore, if the opening 7 is provided, the influence of wind can be reduced. [Explanation of symbols]
