Description

  The present invention relates to a vehicle alert plate, and more particularly to a vehicle alert plate that can efficiently generate vibration noise when passing through the vehicle.

  In road construction sites, measures such as installing a cushion drum and an arrow plate are taken to guide the vehicle. However, since these are visual and have no effect on vehicles that fall asleep, traditionally, a step is formed by laying on the road surface in front of the road construction section. A vehicle alert plate is used to alert a driver to notice that there is a road construction section ahead by generating a vibration sound (Patent Documents 1 and 2).

  Since the thing of patent document 1 is a plate-shaped object which does not have the projection which generates a vibration sound when a vehicle passes on an upper surface, the vibration sound when a vehicle passes will become a single shot, and an alerting effect is produced. Low. Although the vibration noise can be increased by forming the plate thickness large, the step with the road surface becomes large and the impact when passing through the vehicle increases. Even in the present situation, if it exceeds 20 mm, there may be a problem particularly when passing a precision component-equipped vehicle or a racehorse-equipped vehicle.

  On the other hand, the thing of patent document 2 generates a vibration sound at the time of passing of a vehicle by providing four large convex parts over the length direction on the upper surface of a plate main body, and a plurality of small convex parts in the center. To be able to.

JP 2003-41529 A Japanese Patent Laid-Open No. 10-88509

  As a result of confirmation by the present inventor, as described in Patent Document 2, even if a large number of protrusions extending in the length direction are provided on the upper surface of the plate body, the vibration sound as expected when passing the vehicle is generated. I could not. This is thought to be because the upper surface is almost flat due to a large number of convex portions, resulting in a single vibration sound.

  Then, this invention makes it a subject to provide the alert plate for vehicles which can generate a vibration sound efficiently at the time of vehicle passing.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
FIG. 1 is a partial perspective view of a vehicle alert plate according to the first embodiment, and FIG. 2 is a sectional view thereof.

  The vehicle alert plate 1 is provided with a plurality of ridges 11 projecting from the upper surface 10a of the plate body 10, and can be pasted on the lower surface 10b of the plate body 10 for fixing to the road surface. A fixing member 13 is provided.

  The plate body 10 is formed in a plate shape having a predetermined length that is rectangular when viewed from above by an elastic synthetic resin. In this embodiment, the width W1 is 150 mm, the length L is 1000 mm, and the height H1 is 4 mm. Both sides of the upper surface along the length direction of the plate body 10 are chamfered to form inclined surfaces 12.

  The synthetic resin having elasticity that forms the plate body 10 is arbitrary as long as it has resistance to the treading force of the vehicle, but it is preferable to use polyurethane rubber. Polyurethane rubber can be manufactured by extrusion molding or injection molding if it is thermoplastic, and it can be manufactured by cast molding if it is thermosetting. In the present embodiment, polyurethane rubber having a hardness of around JIS A90 is used. However, a higher hardness is preferred because the magnitude of sound and vibration increases and the alerting effect is high.

  Only two protrusions 11 are provided on the upper surface 10 a of the plate body 10 so as to protrude from the upper surface 10 a of the plate body 10 at a predetermined interval along the length direction of the plate body 10. That is, the upper surface 10 a of the plate body 10 has no protruding portion other than the two protruding strips 11. Accordingly, there is no flat surface between the two ridges 11 and between each ridge 11 to the inclined surface 12.

  As a result, when the vehicle passes over the upper surface of the vehicle alert plate 1, a clear vibration sound is generated when the tire passes over the two ridges 11, and at least twice for the driver. Can be sensed. That is, after the tire has climbed over the first ridges 11, the tire falls into a flat portion between the ridges 11 and subsequently gets over the next ridges 11. Is greatly generated, the alerting effect is high, and the vibration sound can be generated efficiently. In particular, since there is nothing protruding on the upper surface 10a of the plate body 10 other than the two ridges 11, the vibration sound is generated more clearly.

  Each ridge portion 11 is disposed closer to both ends in the width direction than the center portion in the width direction of the plate body 10, and the width direction of each ridge portion 11 is greater than the distance S <b> 1 between the centers in the width direction of the ridge portions 11. The distance S2 from the center to both ends in the width direction of the plate body 10 is shorter. Thereby, the vibration sound at the time of the tire which fell between the protruding item | line parts 11 gets over the 2nd protruding item | line part 11 becomes larger, and the alerting effect can be made higher.

  In the present embodiment, the width W2 of the ridges 11 is 7 mm, and the protrusion height H2 of the ridges 11 from the upper surface 10a of the plate body 10 is 8 mm, but the width W2 is preferably 7 mm to 15 mm. If it is smaller than 7 mm, the strength is insufficient, and if it exceeds 15 mm, the contact area with the tire increases and the vibration becomes weak. On the other hand, if the protrusion height H2 is lower than 5 mm, the generation of vibration noise when the vehicle passes is not clear. Further, when the overall height (H1 + H2) including the plate body 10 exceeds 20 mm, the step height from the road surface becomes large as described above, and thus the protruding height H2 of the protruding strip portion 11 is 5 mm. It is preferable to be set to ˜15 mm.

  The distance S1 is preferably 90 mm to 120 mm from the viewpoint that vibration noise can be generated more efficiently when the vehicle passes.

  The ridges 11 are generally rectangular in cross section, but are preferably trapezoidal in cross section from the viewpoint of ensuring durability against frequent stepping by the vehicle.

  In addition, the ridge 11 can be formed separately from the plate body 10 and then fixed integrally with an adhesive. However, from the viewpoint of ensuring durability against frequent stepping by the vehicle, It is preferable to integrally form the same synthetic resin (polyurethane rubber).

  The fixing member 13 is not formed on the entire lower surface 10 b of the plate body 10, but is formed in two parts from both sides in the length direction of the plate body 10 to below the ridges 11.

  As shown in FIG. 3, the fixing member 13 includes a double-sided adhesive tape 131 that is fixed to the lower surface 10 b of the plate body 10, and a single-sided adhesive that is fixed to the opposite surface of the plate body 10 in the double-sided adhesive tape 131. And the tape 132. The single-sided adhesive tape 132 is disposed on the opposite side of the double-sided adhesive tape 131 so that the adhesive layer faces the road surface. In a state before laying on the road surface, a peeling tape (not shown) is stuck to the adhesive layer of the single-sided adhesive tape 132.

  When the plate member 10 and the road surface are fixed only by the double-sided adhesive tape 131, the fixing member 13 cannot follow the unevenness of the road surface and the plate body 10 is detached from the road surface. On the other hand, when the plate body 10 and the road surface are fixed only by the single-sided adhesive tape 132, it can be firmly fixed to the road surface, but when the single-sided adhesive tape 132 is peeled from the plate body 10, a large amount of adhesive is applied to the lower surface 10b of the plate body 10. Will remain. For this reason, by sticking the double-sided pressure-sensitive adhesive tape 131 and the single-sided pressure-sensitive adhesive tape 132 together, it can be firmly fixed to the road surface, and a large amount of pressure-sensitive adhesive does not remain on the plate body 10.

  As the double-sided pressure-sensitive adhesive tape 131, it is preferable to use a cloth double-sided pressure-sensitive adhesive tape in which a pressure-sensitive adhesive layer made of a rubber-based pressure-sensitive adhesive is formed on both surfaces of a cloth base material.

  Moreover, as the single-sided adhesive tape 132, it is preferable to use a butyl tape in which an adhesive layer made of butyl rubber is formed on one side of a base material made of polyethylene net.

(Second Embodiment)
FIG. 4 is a cross-sectional view of the vehicle alert plate according to the second embodiment. The parts with the same reference numerals as those in FIG. 1 and FIG.

  In the vehicle alert plate 2 according to the present embodiment, a plurality of reinforcing tensile bodies 14 are provided on the plate body 10. Accordingly, the plate body 10 can have high strength and can withstand repeated use over a long period of time.

  The tensile body 14 is made of stainless steel or aramid fiber, and is embedded along the length direction of the plate body 10. In the present embodiment, a total of six tensile bodies 14, two in total between the ridges 11 and two each on the outside of each ridge 11, are not particularly limited. Each tensile member 14 is preferably arranged so as to be close to the upper surface 10a of the plate body 10 to which the stepping load of the vehicle is applied.

  The outer diameter of the tensile body 14 can be selected as appropriate. For example, in the case of stainless steel, one having a diameter of φ0.3 mm to φ1.3 mm can be used. Moreover, in the case of an aramid fiber, the thing of (phi) 0.2mm-(phi) 0.65mm can be used. In the case of an aramid fiber, it is preferable to use a stranded wire.

(Third embodiment)
FIG. 5 is a partial plan view of a vehicle alert plate according to the third embodiment, and FIG. 6 is a sectional view thereof. The parts with the same reference numerals as those in FIG. 1 and FIG.

  In the vehicle alert plate 3 according to the present embodiment, a large number of grooves 15 are provided in the upper surface 10 a of the plate body 10.

  The groove 15 includes a groove 15 a disposed between the two ridges 11 on the upper surface 10 a of the plate body 10, and a groove 15 b disposed on the outside of each ridge 11, and these are the plate body 10. It is recessed along the direction (width direction) orthogonal to the length direction. One groove 15a and two grooves 15b and 15b on the outer side of each ridge portion 11 are arranged in the same straight line in the width direction of the plate body 10, and from these one groove 15a and two grooves 15b and 15b, A set of the plate body 10 is arranged along the entire length.

  Each of the grooves 15a and 15b may be a narrow groove having a width of about 0.5 mm, and is arranged in parallel at a pitch of, for example, 20 mm along the length direction of the plate body 10.

  By providing such a groove 15, the vehicle alert plate 3 according to the present embodiment allows water to flow into the groove 15 even when the upper surface 10 a of the plate body 10 is wet due to sudden rain or the like. Further, it is possible to prevent the upper surface 10a of the plate body 10 from getting wet, and it is possible to make the vehicle difficult to slip.

  In general, the vehicle warning plate 3 before or after use is wound in the length direction to form a compact cylindrical shape, and is unfolded and laid on the road surface during use. In some cases, it may be difficult to bring it into close contact with the road surface. However, the vehicle alert plate 3 according to the present embodiment can alleviate curl due to a large number of grooves 15 arranged in parallel on the upper surface 10a of the plate body 10 and improve the shape stability when laid on the road surface. Can be made.

  In addition, this vehicle alert plate 3 is a preferable embodiment because the tensile body 14 is embedded in the plate body 10 as in the second embodiment, and the strength of the plate body 10 can be secured. However, as in the first embodiment, the tensile body 14 may not be provided.

(Other aspects of vehicle warning plate)
In the above vehicle warning plates 1, 2, and 3, only two protrusions 11 are projected so that at least two vibration sounds can be sensed. The presence of a plurality of protrusions 11 projecting from the upper surface 10a of the vehicle 10 may allow the driver to sense three or more vibration sounds when passing through the vehicle.

(Description of usage state)
FIG. 7 is an explanatory diagram of the usage state of the vehicle alert plate. Although the vehicle alert plate 1 according to the first embodiment is used here, the other vehicle alert plates 2 and 3 are also used in the same manner.

  On the road surface 100 in front of the road construction section, an arrow plate 101 or the like is installed to restrict the lane, but the vehicle alert plate 1 is laid on the road surface 100 several hundred meters in front. Reference numeral 102 denotes a center line.

  The vehicle warning plate 1 has a width W1 of 150 mm and a length L of 1000 mm (see FIGS. 1 and 2), and is formed compactly. It is preferable to arrange the sheets side by side because the effect of continuous vibration noise when passing through the vehicle can be exhibited, and the alerting effect becomes higher. Here, a combination of 3 sheets in the length direction of the vehicle warning plate 1 and 2 sheets in the width direction, a total of 6 sheets is set as one set, and a plurality of sets are laid at intervals along the traveling direction of the vehicle on the road surface 100. Yes. The distance A between each set can be 1 m to 10 m.

  By laying a plurality of sheets as one set in this way, even when damaged, only the damaged part can be peeled off from the road surface 100 and replaced, and the maintainability is improved. Moreover, even if it peels off from the road surface 100 during use, since it is compact in size, it is unlikely to be a secondary disaster.

  FIG. 8 shows a mode in which two sets of vehicle alert plates 1 arranged side by side in the width direction are set as one set, and each set is arranged in a staggered manner with different laying methods.

  When arranged in a zigzag manner in this way, since only one wheel rides when passing through the plate, the generation of sound and vibration is slightly smaller than the arrangement mode in which both wheels ride as shown in FIG. Since the vehicle rides on the left and right alternately, a lateral vibration is also generated, and it is possible to effectively give a vibration to a driver such as a snooze driving and effectively call attention.
