[Technical Field]

[0001] The present invention relates to a display device that has an arrow marking on the display section that indicates the direction from the starting point to the end point, and that is suitable for use as a road direction guide. [Background technology]

[0002] Arrow signs are installed to guide drivers to change lanes on roads under construction, etc. A typical arrow sign has an arrow displayed on the surface of two metal plates connected in a downward-opening shape.

[0003] These types of general arrow signs can move or fall over when strong winds blow, making them unable to properly display information. There is also the risk that they could collide with pedestrians or moving vehicles, causing serious problems in terms of traffic safety.

[0004] The arrow board described in Patent Document 1 is a sign board that opens downward when viewed from the side and is formed in a mesh pattern, with an arrow marked in the center of the sign board.It is proposed that air passes through the mesh of the sign board to prevent it from falling over in strong winds. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Registered Utility Model No. 3138352 Summary of the Invention [Problem to be solved by the invention]

[0006] With an arrow board such as that described in Patent Document 1, the arrows are difficult to see due to the presence of numerous ventilation holes formed in the sign board, making it difficult to recognize the direction indicated by the arrows. As a result of research, the inventors of the present invention have found that the placement of the ventilation holes makes the arrows more visible.

[0007] The present invention was made based on the above findings, and aims to provide a display device that uses ventilation holes to prevent tipping over and allows the direction indicated by the arrow sign to be clearly visible. [Means for solving the problem]

[0008] The invention of claim 1 is a display device comprising a display unit having an arrow sign indicating the direction from the starting point to the end point, and a ventilation hole arrangement area outside the outline of the arrow sign and in which a plurality of ventilation holes are arranged, wherein the ventilation hole arrangement area is located from one side to the other side of a straight line passing through the starting point and the end point of the arrow sign, and the plurality of ventilation holes comprise radially arranged ventilation holes arranged in a row radially from the starting point side to the end point side of the arrow sign.

[0009] A second aspect of the present invention is the display device according to the first aspect, wherein the arrow indicator portion has a shape that becomes thicker from the starting point toward the end point.

[0010] The invention of claim 3 is a display device described in claim 1 or 2, characterized in that the radially arranged ventilation holes have long and short ventilation holes with an opening shape having a long direction and a short direction, and the long and short ventilation holes have radially arranged long ventilation holes in a row with the long direction of the opening facing radially from the starting point side to the end point side of the arrow sign portion.

[0011] A fourth aspect of the present invention is the display device according to the third aspect, wherein the elongated radial ventilation holes are diamond-shaped ventilation holes.

[0012] A fifth aspect of the present invention is the display device according to the third aspect, wherein the elongated radial ventilation holes include elliptical ventilation holes having an elliptical shape.

[0013] The invention of claim 6 is the display device described in claim 3, characterized in that the radial elongated ventilation holes are arranged in a row so that at least one of the longitudinal and lateral directions of the opening shape gradually becomes larger radially from the starting point side of the arrow sign portion toward the end point side.

[0014] The invention according to claim 7 is the display device according to claim 1 or 2, characterized in that a fluorescent band line is formed inside and along the outline of the arrow marking portion.

[0015] The invention of claim 8 is a display device as described in claim 1 or 2, characterized in that a handle hole is formed at the end of the display unit, and the handle hole has an inwardly convex curved shape. [Effects of the Invention]

[0016] The display device of the present invention has a plurality of ventilation holes arranged in the ventilation hole arrangement area, so that it is difficult to move or fall down even when exposed to strong winds, and therefore, it is possible to prevent the loss of the function of indicating direction and the occurrence of accidents such as hitting passersby or moving vehicles. In addition, the arrow marker is provided with radially arranged ventilation holes that are arranged in a row radially from the starting point side to the end point side, so that the row of radially arranged ventilation holes complements the direction indicated by the arrow marker, and as a result, the direction indicated by the arrow marker can be clearly seen.

[0017] In addition, by making the arrow marker portion thicker from the start point to the end point, the direction indicated by the arrow marker portion is emphasized and visibility is improved.

[0018] In addition, if the ventilation holes are long and short ventilation holes with opening shapes such as diamonds or ellipses having a longitudinal direction and a transverse direction, and if radial elongated ventilation holes are provided that are arranged in rows with the longitudinal direction of the opening oriented radially from the starting point side to the end point side, or if the radial elongated ventilation holes are arranged in rows that gradually become larger radially from the starting point side to the end point side, the effect of emphasizing the direction indicated by the arrow marking section is further enhanced.

[0019] In addition, a fluorescent band is formed along the inside of the outline of the arrow marker, making it easy to see the direction indicated by the arrow marker even when the device is installed in a poorly lit environment.

[0020] In addition, by forming a handle hole with an inwardly convex curve at the end of the display unit, when you insert your finger into the handle hole and grip it, the handle hole and your bent finger fit comfortably together, making it easy to grip. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0022] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. However, it goes without saying that the present invention is not limited to the embodiments described below.

[0023] [First embodiment] 1 to 3 show a first embodiment of the present invention. FIG. 1 is a front view of the display device, FIG. 2 is a side view of the display device, and FIG. 3 is a perspective view of the display device.

[0024] In the first embodiment, the display device 1 is a device that is installed on a road to provide direction guidance, and includes two display units 2 and a connecting member 3 that connects the two display units 2 together.

[0025] The display unit 2 is made of a rectangular plate-like material such as a metal, such as iron or aluminum. The two display units 2 are joined by a joining member 3 arranged along one long side (upper side) so as to gradually widen toward the other long side (lower side) in a mountain shape when viewed from the side.

[0026] When the display device 1 is installed on a road or the like, the connecting member 3 becomes the top, and the other long side of the unfolded display unit 2 becomes the bottom. Furthermore, a substantially rectangular gripping hole 30 is formed in the center of the connecting member 3.

[0027] On both the left and right sides (the ends on the short sides) of the two display units 2, handle holes 20 are formed that are curved convexly inward. The handle hole 20 has a curved shape, so when a finger is inserted into the handle hole 20 and gripped, the bent finger fits comfortably into the handle hole 20, making it easy to grip.

[0028] On the surfaces of the two display units 2 (opposite surfaces and opposite surfaces), an arrow mark portion 21 and a ventilation hole arrangement area portion 22 are formed.

[0029] The arrow mark 21 is an arrow mark having a rod-shaped portion 210 displayed in a straight line and extension portions 211 extending from one end of the rod-shaped portion 210 on both sides. A starting point 21a and an end point 21b are set at two predetermined points on the display unit 2, and the base end of the arrow (the base end of the rod-shaped portion 210) is located at the starting point 21a, and the tip of the arrow (the tip of the protruding portion 211) is located at the end point 21b.

[0030] In this embodiment, the starting point 21a and the end point 21b are set so that a straight line 21c passing through the starting point 21a and the end point 21b is positioned parallel to the long side of the display unit 2, i.e., in the horizontal direction and approximately at the center in the height direction, and the starting point 21a is set on the right side in Figure 1, and the end point 21b is set on the left side in Figure 1.

[0031] Therefore, arrow marker unit 21 has rod-shaped portion 210 disposed at the approximate center in the height direction, which was previously the horizontal direction, and protruding portion 211 disposed continuously from one end of rod-shaped portion 210, indicating the direction from start point 21a to end point 21b (the direction from right to left in FIG. 1). In other words, arrow marker unit 21 of this embodiment encourages a viewer to head left.

[0032] The arrow mark portions 21 are displayed so as to point in the same direction on the two display portions 2, and the bar-shaped portions 210 are shaped so as to gradually become thicker from the starting point 21a toward the end point 21b.

[0033] The inside of the outline 21d of the arrow mark portion 21 is colored in an attention-grabbing color such as red. A fluorescent band 212 is drawn inside the outline 21d of the arrow mark portion 21 along the outline 21d.

[0034] Even at night or in a dark environment, the fluorescent band line 212 shines in the shape of an arrow, so that the direction from the start point 21a of the arrow marker portion 21 to the end point 21b can be clearly indicated. The area outside the outline 21d of the arrow mark portion 21 of the display portion 2 is colored in a color different from that of the arrow mark portion 21.

[0035] Ventilation hole arrangement area 22 is an area outside contour 21d of arrow marked portion 21, and is located from one side to the other side of straight line 21c passing through starting point 21a and ending point 21b of arrow marked portion 21. In other words, ventilation hole arrangement area 22 is an area outside contour 21d of arrow marked portion 21, and is located from the upper side to the lower side of straight line 21c.

[0036] In the ventilation hole arrangement region 22, a plurality of ventilation holes 220 are arranged. The ventilation holes 220 are formed by penetrating the plate-like body of the display unit 2 .

[0037] Of the ventilation holes 220, a pair of ventilation holes 220a are each formed in a triangular shape and are located adjacent to the starting point 21a of the protruding portion 211 of the arrow sign portion 21, with one side along the edge of the protruding portion 211 on the starting point 21a side and the other side along the upper and lower edges of the rod-shaped portion 210. The pair of triangular ventilation holes 220a are arranged symmetrically with respect to the line 21c.

[0038] A plurality of elongated, rod-like rectangular ventilation holes 220b with openings in the longitudinal and lateral directions are formed adjacent to the upper and lower long sides of the rod-shaped portion 210 of the arrow sign portion 21. The rectangular ventilation holes 220b are arranged in a region extending from the start point 21a to the end point 21b of the arrow sign portion 21.

[0039] The rectangular ventilation hole 220b is arranged such that its longitudinal direction is horizontal and its lateral direction is vertical. Specifically, the rectangular ventilation hole 220b is trapezoidal, with its opposite parallel sides in the lateral direction oriented substantially in the height direction of the display unit 2, and one side of each of its opposite non-parallel sides in the longitudinal direction aligned with the upper and lower long sides of the rod-shaped portion 210.

[0040] Because rod-shaped portion 210 has a shape that gradually becomes thicker at the same rate from start point 21a to end point 21b, rectangular ventilation holes 220b are arranged in rows radially from start point 21a to end point 21b. Specifically, rectangular ventilation holes 220b are arranged in two radial rows of three from start point 21a to end point 21b. The rectangular ventilation holes 220b are arranged in rows radially from start point 21a to end point 21b, with the longitudinal direction of the openings facing in the rows.

[0041] These rectangular ventilation holes 220b correspond to the radially arranged ventilation holes of the present invention. Furthermore, these rectangular ventilation holes 220b correspond to the long and short ventilation holes of the present invention, and correspond to the radially elongated ventilation holes of the present invention.

[0042] The rectangular ventilation holes 220b arranged along the upper long side of the rod-shaped portion 210 and the rectangular ventilation holes 220b arranged along the lower long side of the rod-shaped portion 210 are arranged so as to be symmetrical with respect to the straight line 21c.

[0043] Moreover, the rectangular ventilation holes 220b are arranged in a row so that the dimension of the opening in the longitudinal direction gradually increases from the start point 21a side of the arrow marked portion 21 toward the end point 21b side.

[0044] The ventilation holes 220c other than the ventilation holes 220a and 220b are diamond-shaped ventilation holes 220c arranged in a radial row from the starting point 21a side of the arrow marked portion 21 toward the end point 21b side.

[0045] Diamond-shaped ventilation holes 220c are arranged in a region extending from start point 21a to end point 21b of arrow mark portion 21. Diamond-shaped ventilation hole 220c has an opening shape with a diagonal line in the longitudinal direction and a diagonal line in the lateral direction.

[0046] In the diamond-shaped ventilation hole 220c of this embodiment, the diagonal lines in the longitudinal direction are arranged along the lines that form the radial shape, and the diagonal lines in the lateral direction are arranged in the vertical direction to emphasize the radial shape and make the arrows stand out, and the diagonal lines in the longitudinal direction and the diagonal lines in the lateral direction are not completely perpendicular to each other, so the shape is not a perfect diamond (it is a so-called parallelogram), but it may be a perfect diamond.If it is a perfect diamond, the diagonal lines in the longitudinal direction may be arranged along the lines that form the radial shape.

[0047] Diamond-shaped ventilation holes 220c are arranged in a radial row further outward than the radial row of square-shaped ventilation holes 220b.

[0048] A plurality of diamond-shaped ventilation holes 220c are arranged in rows along lines that radiate from the starting point 21a of the arrow mark portion 21 toward the end point 21b.

[0049] Specifically, on one side (upper side) of the straight line 21c, diamond-shaped ventilation holes 220c are arranged from the starting point 21a side toward the end point 21b side, with five in the first row (the fifth one is on the end point 21b side of the protrusion 211) from the side closest to the square ventilation hole 220b, six in the second row (the sixth one is on the end point 21b side of the protrusion 211), five in the third row, and four in the fourth row, and these rows are arranged in four radial directions.

[0050] Furthermore, on one side (upper side) of the straight line 21c, a diamond-shaped ventilation hole 220c1 is arranged on the radial line formed between the first and second rows, closer to the end point 21b than the fifth hole in the first row and the sixth hole in the second row, and a diamond-shaped ventilation hole 220c2 is also arranged on the radial line formed between the first row and the straight line 21c, closer to the end point 21b than the fifth hole in the first row.

[0051] The diamond-shaped ventilation holes 220c (including 220c1, 220c2) on the other side (lower side) of the straight line 21c are arranged symmetrically with the diamond-shaped ventilation holes 220c (including 220c1, 220c2) on one side (upper side) of the straight line 21c, except for the fourth row. Two diamond-shaped ventilation holes 220c are arranged in the fourth row on the other side (lower side) of the straight line 21c.

[0052] Diamond-shaped ventilation holes 220c are arranged in a row so that the opening dimensions in the longitudinal and lateral directions gradually increase from the start point 21a side of arrow marked portion 21 toward the end point 21b side.

[0053] These diamond-shaped ventilation holes 220c (including 220c1 and 220c2) correspond to the radially arranged ventilation holes of the present invention. Furthermore, these diamond-shaped ventilation holes 220c (including 220c1 and 220c2) correspond to the long and short ventilation holes of the present invention, and correspond to the radially elongated ventilation holes of the present invention.

[0054] Since the ventilation holes 220 are provided in the ventilation hole arrangement area 22, the display device 1 is unlikely to move or tip over due to strong winds, and is highly stable. The arrow sign 21 has a shape that becomes thicker from the starting point 21a toward the end point 21b, which emphasizes the direction indicated by the arrow sign 21 and easily attracts the attention of passersby and drivers.

[0055] The rectangular ventilation holes 220b and diamond-shaped ventilation holes 220c are arranged in rows radially from the starting point 21a of the arrow marking section 21 toward the end point 21b, facing the longitudinal direction, and gradually becoming larger, so that the direction indicated by the arrow marking section 21 is further emphasized by the other ventilation holes 220c and can be seen more clearly.

[0056] Second Embodiment A second embodiment of the present invention will be described with reference to Fig. 4. Note that a description of the same parts as in the first embodiment will be omitted, and the following mainly focuses on the different parts. FIG. 4 is a front view of a display device showing the second embodiment.

[0057] The second embodiment differs from the first embodiment in that the diamond-shaped ventilation hole 220c is changed to an elliptical ventilation hole 220d having an opening shape with a longitudinal direction and a lateral direction.

[0058] The oval ventilation hole 220d is arranged in a region extending from the start point 21a to the end point 21b of the arrow mark portion 21. The elliptical ventilation hole 220d has an opening shape with a major axis in the longitudinal direction and a minor axis in the lateral direction.

[0059] The elliptical ventilation hole 220d of this embodiment has its major axis aligned along the line that forms the radial shape, and its minor axis aligned vertically to emphasize the radial shape and make the arrows stand out. The major and minor axes are not perfectly perpendicular to each other, so it is not a perfect ellipse (it is a deformed ellipse with the direction of the minor axis changed), but it may be a perfect ellipse. If it is a perfect ellipse, the major axis may be aligned along the line that forms the radial shape.

[0060] Similar to the diamond-shaped ventilation holes 220c of the first embodiment, the elliptical ventilation holes 220d are arranged in rows along lines that radiate from the starting point 21a of the arrow marking portion 21 toward the end point 21b.

[0061] An elliptical ventilation hole 220d1 is arranged similar to the diamond-shaped ventilation hole 220c1 in the first embodiment, and an elliptical ventilation hole 220d2 is arranged similar to the diamond-shaped ventilation hole 220c2 in the first embodiment.

[0062] In addition, the elliptical ventilation holes 220d are arranged in a row so that the dimensions of the long and short diameters of the openings, i.e., the dimensions of the openings in the longitudinal and transverse directions, gradually increase from the starting point 21a side of the arrow marking portion 21 toward the end point 21b side.

[0063] These elliptical ventilation holes 220d (including 220d1 and 220d2) correspond to the radially arranged ventilation holes of the present invention. Furthermore, these elliptical ventilation holes 220d (including 220d1 and 220d2) correspond to the long and short ventilation holes of the present invention, and correspond to the radially elongated ventilation holes of the present invention.

[0064] [Third embodiment] The third embodiment will be described with reference to FIG. Note that explanations of parts that are the same as those in the first and second embodiments will be omitted.

[0065] In the third embodiment, the arrow marking portion 21 is colored (graded) so that the color gradually changes from light to dark from the starting point 21a to the end point 21b, thereby expressing a strong sense of dynamism as if the arrow is jumping out from the starting point 21a to the end point 21b.

[0066] No fluorescent band 212 is provided inside the outline 21d of the arrow mark portion 21, and a ventilation hole non-arrangement area 23 in which no ventilation holes 220 are provided is formed with a constant width surrounding the outside of the outline 21d.

[0067] All ventilation holes 220 are elliptical, but the elliptical opening shape of ventilation hole 220 is partially cut out in the portion located in ventilation hole non-arrangement area 23 around arrow marked portion 21. Therefore, outline 21d of arrow marked portion 21 surrounded by ventilation hole non-arrangement area 23 becomes clear.

[0068] A plurality of ventilation holes 220 are arranged in rows along lines that radiate from the start point 21a side of the arrow mark portion 21 toward the end point 21b side.

[0069] Specifically, on one side (upper side) of the straight line 21c, the ventilation holes 220 are arranged from the starting point 21a side toward the end point 21b side, with 10 holes in the first row (the 9th and 10th holes are on the end point 21b side of the protrusion 211), 10 holes in the second row (the 9th and 10th holes are on the end point 21b side of the protrusion 211), 11 holes in the third row (the 9th to 11th holes are on the end point 21b side of the protrusion 211), 11 holes in the fourth row (the 9th to 11th holes are on the end point 21b side of the protrusion 211), 9 holes in the fifth row (the 9th hole is on the end point 21b side of the protrusion 211), and 8 holes in the sixth row, and these rows are arranged in six radial directions.

[0070] The ventilation holes 220 on the other side (lower side) of the straight line 21c are arranged symmetrically with the ventilation holes 220 on one side (upper side) of the straight line 21c with respect to the straight line 21c.

[0071] The ventilation hole 220 is formed from the start point 21a of the arrow mark portion 21 to the area of ​​the display portion 2 beyond the end point 21b. In this embodiment, the ventilation holes 220 are formed from the starting point 21a, but they may be formed from outside the starting point 21a.

[0072] In this embodiment, similar to the elliptical ventilation holes 220d of the second embodiment, the openings are arranged in a row so that the dimensions of the long and short diameters of the openings, i.e., the dimensions of the openings in the longitudinal and lateral directions, gradually increase from the starting point 21a side of the arrow marking portion 21 toward the end point 21b side, but the elliptical shape of the ventilation hole 220 closest to the starting point 21a side is arranged so as to be closer to a circle. Alternatively, the opening of the ventilation hole 220 closest to the starting point 21a may be circular, and the opening may be gradually oval-shaped toward the end point 21b.

[0073] In this embodiment, unlike the first and second embodiments, the display unit 2 is not provided with a handle hole 20, but it is of course possible to form one.

[0074] [Fourth embodiment] A fourth embodiment of the present invention will be described with reference to FIG. Note that a description of the same parts as those in the first to third embodiments will be omitted, and the following mainly describes the different parts.

[0075] In the fourth embodiment, the arrow sign portion 21 comprises an arrow main body portion 213 having a rod-shaped portion 210 and a protruding portion 211, a first direction support portion 214 formed at a slight distance from the tip side of the protruding portion 211 of the arrow main body portion 213, and a second direction support portion 215 formed at a slight distance from the tip side of the first direction support portion 214.

[0076] The first direction support portion 214 has a shape similar to but larger than the protruding portion 211 of the arrow main body 213, and is a mountain-shaped portion that is arranged parallel to and spaced from the tip edge of the protruding portion 211 of the arrow main body 213.

[0077] The second direction support portion 215 has a shape similar to that of the first direction support portion 214 but is larger than it, and has a mountain shape that is arranged parallel to and spaced from the tip edge of the first direction support portion 214.

[0078] The first direction support portion 214 and the second direction support portion 215 point in the same direction as the direction indicated by the arrow main body portion 213, and the tip of the second direction support portion 215 becomes the end point 21b of the arrow mark portion 21.

[0079] As in the third embodiment, the arrow mark portion 21 is colored (gradationally) so that the color gradually becomes darker from the starting point 21a to the end point 21b.

[0080] All of the ventilation holes 220 are diamond-shaped, but rows of larger ventilation holes 220 and rows of smaller ventilation holes 220 are alternately arranged radially. The ventilation holes 220 in each row are arranged so that the longitudinal and lateral dimensions gradually increase from the starting point 21a side of the arrow marked portion 21 toward the end point 21b side, and so that the ratio of the longitudinal dimension to the lateral dimension gradually increases. In other words, the ventilation holes 220 gradually become thinner and longer from the starting point 21a side of the arrow marked portion 21 toward the end point 21b side.

[0081] In this embodiment, the direction indicated by the arrow marked portion 21 is emphasized by varying the shape of the arrow marked portion 21 and the size and shape of the ventilation holes 220.

[0082] [Other Modifications] The present invention is not limited to the above-described embodiment, and may also include the following, for example.

[0083] In this embodiment, the arrow mark portion 21 is configured to prompt a viewer to turn left, but the direction of the prompt may be in any direction.

[0084] In this embodiment, the ventilation holes arranged in a radial row have a shape having a longitudinal direction and a lateral direction, but they may also be circular, square, or the like, in which there is no distinction between the longitudinal and lateral directions.

[0085] In this embodiment, the ventilation holes arranged in radial rows are arranged in a shape that gradually increases in size radially from the starting point side to the end point side of the arrow marker section, but ventilation holes of the same shape can also be arranged in radial rows. Furthermore, ventilation holes of different shapes may be arranged in radial rows, such as by arranging diamond-shaped and elliptical ventilation holes alternately. Furthermore, the first row of ventilation holes may be arranged along the radial line 21c, and the second row of ventilation holes may be arranged in a different shape.

[0086] In the first and second embodiments, the ventilation holes arranged in a radial row are arranged in an area extending from the start point to the end point of the arrow marker section, and in the third and fourth embodiments, they are arranged in an area extending beyond the start point to the end point of the arrow marker section, but they may also be arranged in only a part of the area extending from the start point to the end point of the arrow marker section.

[0087] In this embodiment, the two display units are joined in a mountain-shaped configuration when viewed from the side so that they expand from one long side to the other long side, but the two display units may also be rotatably attached to one of the long sides so that they can be opened and closed between a mountain-shaped open state and an overlapping state.

[0088] In the first and second embodiments, the handle holes are provided on both side edges of the display section, but they may be provided on only one side edge.

[0089] Each technical matter in any of the embodiments may be applied to other embodiments to form examples. [Explanation of symbols]
