Description

[Technical Field]

[0001] The present invention relates to a signboard fixing device and a road signboard. [Background technology]

[0002] For example, a road signboard as shown in Patent Document 1 is used to notify motorists of road conditions. This road signboard includes a display panel for displaying road conditions and the like, and legs that support the display panel. The signboard has multiple legs spaced apart across the width of the signboard. Some road signboards also include horizontal bars that extend across the width from the legs and connect the multiple legs together. To prevent such road signboards from falling over or moving due to wind, weights such as sandbags are tied to the horizontal bars of the signboard. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-95344 Summary of the Invention [Problem to be solved by the invention]

[0004] However, when construction work is carried out along a road, if the road signboard is used to announce the work, the road signboard and its weight must be moved along the road as the work progresses. This work of moving the road signboard and its weight along the road is a heavy burden for the workers and causes a decrease in the work efficiency of the work related to the construction work. [Means for solving the problem]

[0005] The means for solving the above problems and their effects will be described below. A standing sign fixing device that solves the above problem includes an attachment portion, a protrusion, and a clamping portion. The attachment portion can be attached to a horizontal bar extending widthwise from the leg of the standing sign. The protrusion protrudes from the attachment portion and is parallel to the leg of the standing sign when the attachment portion is attached to the horizontal bar of the standing sign. The clamping portion is provided on the protrusion, and can be repositioned toward or away from the leg of the standing sign.

[0006] According to the above configuration, the mounting portion of the standing sign fixing device is attached to the horizontal bar of the standing sign, so that the protruding portion of the standing sign fixing device is parallel to the leg of the standing sign. Then, with the standing sign positioned so that a protrusion, such as a curbstone on a road, is located between the protrusion and the leg, the position of the clamping portion of the standing sign fixing device is changed to approach the leg, and the protrusion on the road is clamped between the leg and the clamping portion. This fixes the standing sign to the protrusion. When moving the standing sign, the position of the clamping portion of the standing sign fixing device is changed in a direction away from the leg of the standing sign, thereby releasing the clamping of the protrusion between the leg and the clamping portion. This makes it possible to move the standing sign. As described above, the standing sign can be fixed to and released from the road protrusion simply by moving the clamping portion of the standing sign fixing device closer to or farther away from the leg of the standing sign. Furthermore, the standing sign fixing device can be lighter than the weight used to fix the standing sign, making it easier to move the standing sign. Therefore, the signboard can be easily moved and fixed, which prevents the work of moving the signboard from becoming a heavy burden on the worker and also prevents this from reducing work efficiency.

[0007] In the above-mentioned stand-up sign fixing device, the mounting portion may be removably attached to the horizontal bar portion of the stand-up sign. With this configuration, the attachment position of the attachment part relative to the horizontal bar of the standing signboard can be easily changed in the direction of extension of the horizontal bar. Also, by adjusting the attachment position of the attachment part to match the size of the road protrusion, the range of sizes of the protrusion that can be clamped between the leg of the standing signboard and the clamping part of the standing signboard fixing device can be expanded.

[0008] A road signboard that solves the above problem includes a leg, a protrusion, and a clamping portion. The leg supports a display panel. The protrusion extends parallel to the leg and has a fixed position relative to the leg. The clamping portion is provided on the protrusion and can be moved toward or away from the leg.

[0009] According to the above configuration, when a road signboard is positioned so that a protrusion, such as a curbstone, is located between the protrusion and the leg, the position of the clamping unit is changed to approach the leg, thereby clamping the road protrusion between the leg and the clamping unit. This fixes the road signboard to the protrusion. When moving the road signboard, the position of the clamping unit is changed away from the leg, thereby releasing the clamping of the protrusion between the leg and the clamping unit. This makes it possible to move the road signboard. As described above, simply moving the clamping unit closer to or farther from the leg can fix and release the road signboard to the road protrusion. Furthermore, because the protrusion and the clamping unit can be lighter than the weights used to fix the road signboard, the road signboard can be moved more easily. Therefore, the road signboard can be easily moved and fixed. As a result, the task of moving the road signboard can be prevented from being a heavy burden on the worker, which can also prevent the resulting decrease in work efficiency.

[0010] In the road signboard, a plurality of legs are provided at intervals in the width direction of the display panel. The plurality of legs are connected by a horizontal bar extending in the width direction of the display panel. The protrusion is fixed to the horizontal bar, thereby fixing the relative position of the protrusion to the legs.

[0011] According to the above configuration, the protruding portion and the clamping portion are disposed between the plurality of legs, so that the size of the road signboard can be prevented from increasing due to the provision of the protruding portion and the clamping portion. In the above road signboard, the legs are pairs of legs connected by a horizontal bar. Two pairs of legs are provided in parallel. A protruding portion and a clamping portion are provided for each pair of legs.

[0012] According to the above configuration, the protrusions and clamping portions provided on each pair of legs allow the road signboard to be fixed at multiple points to protrusions on the road, thereby enabling the road signboard to be stably fixed to the protrusions.

[Figure 7] FIG. 3 is a rear view showing another example of the road signboard of FIG. 2. DETAILED DESCRIPTION OF THE INVENTION

[0014] Hereinafter, an embodiment of a standing signboard fixture and a road standing signboard will be described with reference to Figs. As shown in Figure 1, the road signboard 11 comprises a rectangular frame 12, a display panel 13 fixed to the frame 12, a support 14 supporting the frame 12, and a signboard fixing device 23 for fixing the road signboard 11 to the road 16.

[0015] The upper end of the support pole 14 is connected to the upper part of the frame 12 by a pin 15. The support pole 14 is capable of rotating around the center line of the pin 15. The rotation of the support pole 14 around the center line of the pin 15 causes the lower end of the support pole 14 to move closer to or away from the lower end of the frame 12. When the road signboard 11 is being transported, the lower end of the support pole 14 is brought closer to the lower end of the frame 12, thereby causing the road signboard 11 to be folded up into a small size. When the road signboard 11 is being used, the lower end of the support pole 14 is moved away from the lower end of the frame 12, allowing the road signboard 11 to stand on the road 16.

[0016] As shown in FIG. 2, the frame 12 has legs 17 and a horizontal bar 18. The legs 17 are located at both ends of the frame 12 in the width direction, i.e., the left-right direction in FIG. 2, and at the bottom end of the frame 12. The legs 17 protrude downward. The horizontal bar 18 is the bottom end of the frame 12 and extends from one leg 17 in the width direction of the road signboard 11, i.e., the left-right direction in FIG. 2, to connect to the other leg 17. Thus, the frame 12 has a pair of legs 17 connected by the horizontal bar 18. These legs 17 are used to support the frame 12 and the display panel 13 on the road 16. A rubber plate 22 is fixed to the surface of one leg 17 facing the other leg 17. The signboard fixing device 23 is removably attached to the horizontal bar 18 connecting the pair of legs 17. Therefore, the above-mentioned standing signboard fixture 23 can be attached to and detached from the horizontal bar portion 18, thereby making it possible to change the attachment position relative to the horizontal bar portion 18 in the direction in which the horizontal bar portion 18 extends.

[0017] As shown in FIG. 3, the support posts 14 are located at both ends of the road signboard 11 in the width direction, i.e., in the left-right direction in FIG. 3. As described above, the upper ends of these support posts 14 are connected to the frame 12 of FIG. 1 by pins 15. The road signboard 11 has a horizontal bar 21 connecting one support post 14 to the other support post 14. The support posts 14 have legs 20. The legs 20 are located at the lower ends of the support posts 14. The horizontal bar 21 extends from one leg 20 in the width direction of the road signboard 11 and is connected to the other leg 20. Therefore, the support post 14 has a pair of legs 20 connected by the horizontal bar 21. These legs 20 also serve to support the frame 12 and the display panel 13 on the road 16. A rubber plate 22 is also fixed to the surface of one leg 20 corresponding to the other leg 20. The standing sign fixing device 23 is also removably attached to the horizontal bar 21 that connects the pair of legs 20. Therefore, the attachment position of the standing sign fixing device 23 to the horizontal bar 21 in the extension direction of the horizontal bar 21 can be changed by attaching and detaching the standing sign fixing device 23 to and from the horizontal bar 21.

[0018] The legs 17, 20 of the road signboard 11 are made up of two sets of legs: a pair of legs 17 and a pair of legs 20. The pair of legs 17 and the pair of legs 20 are parallel to each other. The signboard fixing devices 23 are attached to the horizontal bar 18 connecting the pair of legs 17 and the horizontal bar 21 connecting the pair of legs 20, respectively.

[0019] <Details of Standing Sign Fixture 23> As shown in Figures 4 and 5, the standing signboard fixture 23 includes an attachment portion 24, a protrusion 25, and a clamping portion 26. As shown in Figures 2 and 3, the attachment portion 24 can be attached to the horizontal bar portions 18, 21 of the road standing signboard 11. Furthermore, the attachment portion 24 attached to the horizontal bar portions 18, 21 in this manner can be detached from the horizontal bar portions 18, 21.

[0020] 4 and 5, the mounting portion 24 is formed by bending a plate material into a concave shape so that it can be fitted onto the horizontal bar portions 18, 21. The mounting portion 24 is formed so that when fitted onto the horizontal bar portions 18, 21, it extends in the same direction as the extension of the horizontal bar portions 18, 21. The mounting portion 24 is provided with a plurality of butterfly bolts 27 for attaching the mounting portion 24 to the horizontal bar portion 18. The butterfly bolts 27 are arranged at predetermined intervals in the extension direction of the mounting portion 24.

[0021] Then, with the mounting portion 24 fitted into the horizontal bar portions 18, 21, the mounting portion 24 is attached to the horizontal bar portions 18, 21 by tightening the plurality of butterfly bolts 27. At this time, the mounting portion 24 is fixed to the horizontal bar portions 18, 21. When the mounting portion 24 is attached to the horizontal bar portions 18, 21 in this manner, loosening the plurality of butterfly bolts 27 releases the mounting portion 24 from the horizontal bar portions 18, 21, making it possible to remove the mounting portion 24 from the horizontal bar portions 18, 21.

[0022] The protrusion 25 of the standing sign fixing device 23 protrudes from the mounting portion 24. When the mounting portion 24 is attached to the horizontal bar portions 18, 21, as shown in FIGS. 2 and 3, the protrusion 25 becomes parallel to the legs 17, 20 of the road standing signboard 11. Note that "parallel" here does not necessarily mean that the distance between the center lines of the legs 17, 20 and the protrusion 25 is constant, but also means that the distance between the center lines is not constant because one center line is tilted to some extent relative to the other. The protrusion 25 is fixed to the horizontal bar portions 18, 21 together with the mounting portion 24. At this time, the relative position of the protrusion 25 to the legs 17, 20 of the road standing signboard 11 is fixed.

[0023] As shown in Figures 4 and 5, the clamping portion 26 of the standing sign fixing device 23 is equipped with a butterfly bolt 28 and a stopper rubber 29. The butterfly bolt 28 penetrates the protruding portion 25 in the width direction, i.e., the left-right direction in Figure 4. The male thread of the butterfly bolt 28 is screwed into the female thread of a nut 30 fixed to the immediate face of the protruding portion 25 in the width direction. The tip of the butterfly bolt 28 protrudes from the nut 30. The stopper rubber 29 is fixed to the tip of the butterfly bolt 28. When the mounting portion 24 is attached to the horizontal bar portions 18, 21, the stopper rubber 29 faces the rubber plates 22 of the legs 17, 20.

[0024] When the butterfly bolt 28 is rotated, the male thread of the butterfly bolt 28 and the female thread of the nut 30 move the butterfly bolt 28 and the stopper rubber 29 of the clamping part 26 in a direction protruding from or approaching the nut 30. When the mounting part 24 is attached to the horizontal bar parts 18, 21, the positions of the butterfly bolt 28 and the stopper rubber 29 change in a direction approaching or moving away from the rubber plates 22 of the leg parts 17, 20 shown in Figures 2 and 3.

[0025] <Effects of the road signboard 11 and the signboard fixing device 23> (1) As shown in Figures 2 and 3, the mounting portion 24 of the standing sign fixing device 23 is attached to the horizontal rod portions 18, 21 of the standing sign, so that the protruding portion 25 of the standing sign fixing device 23 becomes parallel to the legs 17, 20 of the road standing sign 11. This road standing sign 11 is positioned so that a protrusion 31 such as a curbstone on the road 16 is located between the protruding portion 25 and the legs 17, 20 to which the rubber plate 22 is fixed.

[0026] In this state, the position of the clamping part 26 of the standing sign fixing device 23 is changed so as to approach the rubber plate 22 of the legs 17, 20. More specifically, by tightening the butterfly bolt 28 of the clamping part 26, the butterfly bolt 28 and the stopper rubber 29 are brought closer to the rubber plate 22 of the legs 17, 20. As a result, the protrusion 31 on the road 16 is clamped between the rubber plate 22 of the legs 17, 20 and the stopper rubber 29 of the clamping part 26. As a result, the road standing signboard 11 is fixed to the protrusion 31.

[0027] When moving the road signboard 11 fixed to the protrusion 31, the position of the clamping part 26 of the signboard fixing device 23 is changed in a direction away from the legs 17, 20 of the road signboard 11. More specifically, by loosening the butterfly bolt 28 of the clamping part 26, the butterfly bolt 28 and the stopper rubber 29 are moved away from the rubber plates 22 of the legs 17, 20. This releases the clamping of the protrusion 31 between the legs 17, 20 and the stopper rubber 29 of the clamping part 26. As a result, the road signboard 11 can be moved.

[0028] As described above, the standing sign can be fixed to or released from the protrusion 31 on the road 16 simply by moving the position of the clamping portion 26 of the standing sign fixing device 23 closer to or farther away from the rubber plate 22 of the leg portions 17, 20 of the road standing sign 11.

[0029] (2) Compared to when the road signboard 11 is fixed with a weight, the signboard fixing device 23 can be made lighter than the weight. This makes it easier to move the road signboard 11. Therefore, the road signboard 11 can be easily moved and fixed. As a result, the task of moving the road signboard 11 can be prevented from becoming a heavy burden on the worker, and this can also be prevented from becoming a cause of reduced work efficiency.

[0030] (3) The mounting portion 24 of the standing signboard fixture 23 is removably attached to the horizontal bar portions 18, 21 of the road standing signboard 11. This makes it easy to change the mounting position of the mounting portion 24 relative to the horizontal bar portions 18, 21 of the road standing signboard 11 in the direction in which the horizontal bar portions 18, 21 extend. As a result, the mounting position of the mounting portion 24 can be easily adjusted to match the size of the protrusion 31 on the road 16. This adjustment of the mounting position also makes it possible to expand the range of sizes of the protrusion 31 that can be clamped between the rubber plates 22 of the legs 17, 20 of the road standing signboard 11 and the stopper rubber 29 of the clamping portion 26 of the standing signboard fixture 23.

[0031] (4) In the road standing signboard 11, a plurality of legs 17 are provided at intervals in the width direction of the display panel 13, i.e., the width direction of the road standing signboard 11, and the plurality of legs 17 are connected by a horizontal bar 18 extending in the width direction. The mounting portion 24 and the protruding portion 25 of the standing signboard fastener 23 are fixed to this horizontal bar 18. A plurality of legs 20 are also provided at intervals in the width direction of the road standing signboard 11, and the plurality of legs 20 are connected by a horizontal bar 21 extending in the width direction. As a result, the protruding portion 25 and the clamping portion 26 of the standing signboard fastener 23 are disposed between the plurality of legs 17 and between the legs 20, so that the increase in size of the road standing signboard 11 caused by attaching the standing signboard fastener 23 having the protruding portion 25 and the clamping portion 26 to the horizontal bar 18, 21 can be suppressed.

[0032] (5) In the road signboard 11, a signboard fixing device 23 is attached to each of the horizontal bar 18 connecting the pair of legs 17 and the horizontal bar 21 connecting the pair of legs 20. Then, the road signboard 11 is fixed at multiple locations to the protrusions 31 on the road 16 using the protrusions 25 and the clamping portions 26 of the signboard fixing device 23 attached to the horizontal bar 18 and the protrusions 25 and the clamping portions 26 of the signboard fixing device 23 attached to the horizontal bar 21. This allows the road signboard 11 to be stably fixed to the protrusions 31.

[0033] (6) The wing bolts 27 are used to attach the mounting portion 24 to the horizontal bar portions 18, 21. The wing bolts 27 can be easily tightened or loosened by hand by an operator. This makes it possible to easily attach and detach the mounting portion 24 to and from the horizontal bar portions 18, 21 without using tools or the like.

[0034] (7) The wing bolts 28 are used to move the stopper rubber 29 toward or away from the rubber plate 22. The wing bolts 27 can be easily moved by tightening or loosening them by hand. This makes it easy to move the stopper rubber 29 toward or away from the rubber plate 22 without using tools or the like.

[0035] (8) The road signboard 11 is fixed to the protrusion 31 on the road 16 by clamping the protrusion 31 between the rubber plate 22 of the leg 17 and the stopper rubber 29 of the clamping part 26. Therefore, when the road signboard 11 is fixed to the protrusion 31, the leg 17 and the clamping part 26 are less likely to slip relative to the protrusion 31.

[0036] The above embodiment can be modified as follows, for example: The above embodiment and the following modifications can be combined and implemented within the scope of technical compatibility. The mounting portion 24 of the standing sign fixture 23 does not necessarily have to be attached to the horizontal bar portions 18, 21 with a butterfly bolt 27. For example, as shown in Fig. 6, the mounting portion 24 of the standing sign fixture 23 may be attached to the horizontal bar portion 18 with a normal bolt 32 and nut 33. In this case, the mounting portion 24 is fastened to the horizontal bar portion 18 with the bolt 32 and nut 33. Similarly, the mounting portion 24 may also be attached to the horizontal bar portion 21 with a normal bolt 32 and nut 33.

[0037] Instead of attaching the signboard fastener 23 to the road signboard 11, the protrusion 25 may be directly fixed to the horizontal bar 18, 21 by welding or the like. In this case, the position where the protrusion 25 is fixed to the horizontal bar 18, 21 may be the center of the horizontal bar 18, 21 in the longitudinal direction, or may be shifted from the center toward the end of the horizontal bar 18, 21 in the longitudinal direction. When the position where the protrusion 25 is fixed to the horizontal bar 18, 21 is shifted from the center toward the end of the horizontal bar 18, 21 in the longitudinal direction, the following effect can be obtained. That is, by reversing the penetration direction of the butterfly bolt 28 into the protrusion 25 to match the size of the protrusion 31 on the road 16, the range of sizes of the protrusion 31 that can be accommodated can be expanded.

[0038] Furthermore, the protruding portion 25 does not necessarily have to be fixed to the horizontal bar portions 18, 21, but may be fixed to the legs 17, 20 so as to protrude in an arm-like manner from the legs 17, 20 outward in the width direction of the road signboard 11. Furthermore, the arm-like protruding portion 25 may be fixed to a location on the frame 12 other than the leg 17, or to a location on the support 14 other than the leg 20.

[0039] As shown in Fig. 7, the leg 17 may also function as a protrusion. In this case, the wing bolt 28 of the clamping part 26 passes through the leg 17. Note that the leg 20 may also function as a protrusion. In this case, the wing bolt 28 of the clamping part 26 passes through the leg 20.

[0040] The rubber plate 22 does not necessarily have to be fixed to the legs 17, 20. The signboard fixing device 23 may be attached to only one of the horizontal bar portion 18 and the horizontal bar portion 21.

[0041] If the road signboard 11 is to be used by leaning it against some kind of structure, the support pole 14 may be omitted. [Explanation of symbols]
