Since the angle formed by the orthogonal direction with respect to the longitudinal direction is 5 to 10 °, it intersects the traveling direction of the vehicle approaching the sidewalk side at an angle closer to a right angle, so that the tire of the vehicle and one side of the recess The contact time is shortened, and more stable contact sound and vibration are generated.

  FIG. 1 is a schematic perspective view showing a use state of a side groove block according to the first embodiment of the present invention, and FIG. 2 is an enlarged sectional view taken along line II-II shown in FIG.

  Referring to these drawings, the side groove block 17 is configured around a trunk body 19 having a substantially rectangular parallelepiped shape, and the trunk body 19 is formed with a cavity 20 penetrating to both ends in the longitudinal direction. ing. In the side groove block 17 according to this embodiment, a portion corresponding to the slit 64 in the side groove block 57 of FIG. 13 shown as the conventional example is not formed, and the upper surface portion 21 is entirely closed. It is in the state.

  The trunk body 19 is installed on the basic crushed stone 27 through the leveling mortar 30. On the roadway side, the roadway asphalt 29 is constructed on the basic crushed stone 28 so that the upper surface thereof is aligned with the surface of the upper surface portion 21 of the side groove block 17. On the other hand, on the sidewalk side, a sidewalk asphalt 32 is constructed on the basic crushed stone 31, and the pedestrian boundary block 33 is fitted in the recess 22 of the trunk body 19 at the boundary with the side groove block 17. It is attached.

  A plurality of concave portions 23 having a rectangular shape in plan view are formed on the upper surface portion 21 of the trunk body 19 at regular intervals in the longitudinal direction of the trunk body 19. The upper surface portion 21 of the trunk body 19 is formed in an inclined state so as to descend from the roadway asphalt 29 toward the walking road boundary block 33. Accordingly, the bottom surface of the recess 23 is similarly inclined to the walking road boundary block 33 side. And the opening which consists of the position by the side of the pedestrian road boundary block 33 of the recessed part 23, ie, the part corresponded in the downward position of the recessed part 23, and the cavity 20 is formed. As shown in FIG. 2, the round hole 24 has a cross-sectional shape in which the opening area increases from the bottom surface of the recess 23 toward the cavity 20. This effect will be described later.

  Since the concave portion 23 is formed in the upper surface portion 21 of the trunk body 19 as described above, at least a part of the remaining portion 25 of the upper surface portion 21 where the concave portion 23 is not formed crosses the longitudinal direction of the trunk body 19. Will be located.

  Next, with reference to FIG. 1, it is assumed that the vehicle approaches the walking road boundary block 33 and the front wheel tire has entered in the direction indicated by the arrow. In this case, since the remaining portion 25 of the upper surface portion 21 of the trunk body 19 is formed in a direction crossing the longitudinal direction of the trunk body 19, the front wheel tires get over the pedestrian boundary block 33. Become. As a result, abnormal contact sounds and vibrations are generated. Since the remaining portions 25 are present at regular intervals in the longitudinal direction, contact sounds and vibrations are continuously generated at regular intervals, which is a stable warning. This alerts pedestrians and drivers and improves safety.

  Next, the draining action of rainwater and the like in the side groove block according to this embodiment will be described.

  Rainwater or the like generated on the roadway asphalt 29 flows into the walking road boundary block 33 side due to the inclination of the roadway asphalt 29. The rainwater that has flowed flows into the recess 23 from the upper surface portion 21 of the trunk body 19. Since the upper surface portion 21 of the trunk body 19 is inclined so as to be lowered toward the walking road boundary block 33 as described above, rainwater that has flowed into the concave portion 23 is also collected on the walking road boundary block 33 side. Since the round hole 24 inserted into the cavity 20 is formed in this part, the rainwater flowing into the recess 23 is discharged into the cavity 20 through the round hole 24. Since the discharging action of the round hole 24 is always performed, there is no possibility that rainwater remains on the upper surface portion 21 and the concave portion 23 of the trunk body 19. Therefore, problems such as mud splash and slip due to the vehicle passing over the upper surface portion 21 of the trunk body 19 are also reduced. Further, since the round hole 24 is formed in such a shape that its cross-sectional area widens as it goes to the cavity 20 as described above, foreign matters such as sand and dust flowing together with rain water flowing into the recess 23 are also clogged in the round hole 24. Without being discharged into the cavity 20. Therefore, the cleaning effect on the upper surface portion 21 of the trunk body 19 is also preferable.

  Next, the durability of the upper surface portion 21 of the side groove block 17 according to this embodiment will be described.

  Referring to FIG. 2, the upper surface portion 21 of the trunk body 19 is configured to align with the upper surface of the roadway asphalt 29. Therefore, the protrusion as shown in the conventional example is not formed on the upper surface portion 21 from the alignment surface. Therefore, there is no need to worry about wear on the protrusion as in the conventional example. On the other hand, since the concave portion 23 is formed below the alignment surface, and the remaining portion 25 of the upper surface portion 21 becomes relatively higher than the bottom surface of the concave portion 23, the same warning as that of the protrusion shown in the conventional example. Sound and vibration can be generated.

  Further, when the snow removal plate 34 passes over the upper surface portion 21 of the trunk body 19 in the snow removal operation in the cold region, no protrusions or the like are formed on the upper surface portion 21, so that the upper surface portion of the snow removal plate 34 is formed. It can be said that there is no concern about 21 wear or the like.

  FIG. 3 is a schematic diagram for explaining the manufacturing advantages of the side groove block shown in FIG.

  Referring to the drawing, in (1), the cross-sectional shape of the upper mold 36 for manufacturing a normal side groove block 57 in which the concave portion 23 is not formed on the upper surface portion 21 of the side groove block 17 is as follows. It is shown. That is, the inner surface 37 of the upper mold 36 is a flat surface corresponding to the upper surface portion 21 of the side groove block 57.

  In (2), it is a side groove block 17 corresponding to the side groove block 57 as shown in FIG. 1, and the cross section of the upper mold 36 in the case where the concave portion 23 is formed on the upper surface portion 21. The shape is shown. A plate 38 corresponding to the concave portion 23 of the side groove block 17 is attached to the inner surface 37 of the upper mold 36. As a result, a recess 23 is formed in the upper surface portion 21 of the side groove block 17. That is, as the upper mold 36, the side groove block 17 can be easily manufactured only by attaching the plate 38 to the inner surface 37 of the mold for manufacturing a normal side groove block conventionally used. . Therefore, the shape of the concave portion 23 formed in the upper surface portion 21 can be made arbitrary by detaching the plate 38 having various forms from the mold 36.

  Thus, in the present invention, since the side groove block 17 can be easily manufactured using the existing upper mold 36, there is a great merit in terms of manufacturing the side groove block 17.

  FIG. 4 is a schematic perspective view showing a usage state of the side groove block according to the second embodiment of the present invention.

  Since the description is basically the same as that according to the first embodiment, the difference will be mainly described.

  Referring to the figure, in this embodiment, the shape of recess 23 formed in upper surface portion 21 is greatly different. That is, the recess 23 has a trapezoidal shape in plan view. And the upper base 12 used as the short side is arrange | positioned so that it may be located in the walkway boundary block 33 side, and the several recessed part 23 is formed in the longitudinal direction of the block 17 for side grooves at predetermined intervals. The side 11a of the concave portion 23 on the vehicle traveling direction side is inclined by an angle α with respect to the direction orthogonal to the longitudinal direction of the side groove block 17. Further, the side 11 b facing the side 11 a on the vehicle traveling direction side of the trapezoidal shape of the recess 23 is formed to be orthogonal to the longitudinal direction of the side groove block 17. The angle α may be 1 to 30 °, but is more preferably 5 to 10 °, and the advantage thereof will be described later with reference to FIG.

  Further, since the round hole 24 is disposed on the upper base 12 side of the concave portion 23 in a trapezoidal shape in plan view, rainwater that has flowed into the concave portion 23 can be intensively discharged into the cavity 20 of the side groove block 17. .

  FIG. 5 is a view showing a relationship between the concave portion of the side groove block according to the embodiment shown in FIG. 4 and the vehicle.

  In FIG. 5, a trapezoidal shape surrounded by a solid line indicates the concave portion 23 of FIG. 4, and a dotted line indicates a rectangular concave portion. 5 shows the roadway X on the right side and the sidewalk Y on the left side. An alternate long and short dash line arrow N indicates the longitudinal direction of the side groove block 17, and a solid line arrow M indicates the traveling direction of the tire of the vehicle.

Since the rectangular side BD indicated by the dotted line is located in a direction orthogonal to the arrow N, the angle α between the side AC of the invention according to this embodiment and the side BD is ∠AOB. Next, the angle y formed by the arrows N and M is な る EOF. In addition, angles θ ₁ and θ ₂ formed by the arrow M and each of the side AC and the side BD are ∠COG and ∠DOG, respectively.

In general, assuming that the approach angle of the tire is more than 10 ° when the longitudinal direction of the side groove block 17 of the vehicle deviates and approaches the sidewalk,
y> 10 ° (1)
It becomes.

On the other hand, from FIG. 5, θ ₂ > θ ₁ = y + 90 ° −α = 90 ° + (y−α) (2)
In the invention according to this embodiment,
10 ° ≧ α ≧ 5 ° (3)
Therefore, from the formulas (1) and (3), y-α> 0
It becomes. Therefore, from equation (2), θ ₂ > θ ₁ > 90 °
It becomes.

As a result, when the vehicle tire approaches the sidewalk at an approach angle y exceeding 10 °, the side AC of the invention of this embodiment is determined from the angle θ ₂ formed by the side BD of the rectangular recess and the arrow M. And the angle θ ₁ formed by the arrow M approaches 90 °.

If theta ₁ approaches 90 °, the tire of the vehicle because the contact time between the tire and the lateral side when the ride on the side AC is shortened, contact noise and vibration is increased.

For the other side HI having a trapezoidal shape in plan view, the tire entry angle y when the vehicle side groove block 17 deviates in the longitudinal direction and approaches the sidewalk is the invention according to this embodiment. When the side AC is equal to or smaller than the angle α formed by the side BD, the angle θ ₃ between the arrow M and the side HI approaches 90 ° as the angle y approaches zero.

  Therefore, in the invention according to this embodiment, the tire approach angle y when the side groove block 17 of the vehicle deviates in the longitudinal direction and approaches the sidewalk is the same as the side AC of the invention according to this embodiment. When the angle formed with the BD is less than or equal to α, stable contact sound and vibration can be generated.

  FIG. 6 is a schematic perspective view showing a use state of the side groove block according to the third embodiment of the present invention.

  Since this embodiment is basically the same as that according to the first embodiment, the difference will be mainly described.

  Referring to the figure, in this embodiment, the shape of recess 23 formed in upper surface portion 21 is greatly different. That is, the recess 23 has a parallelogram shape in plan view. A plurality of recesses 23 are formed at predetermined intervals in the longitudinal direction of the side groove block 17. The side 11 a of the concave portion 23 on the parallelogram-shaped side in the vehicle traveling direction is inclined by an angle α with respect to the direction orthogonal to the longitudinal direction of the side groove block 17. In addition, the side 11 b of the concave portion 23 facing the side 11 a of the parallelogram shaped vehicle traveling direction is naturally inclined at an angle α with respect to the direction perpendicular to the longitudinal direction of the side groove block 17. As described above with reference to FIG. 5, the angle α is preferably 5 to 10 ° from the viewpoint of increasing contact sound and vibration.

  FIG. 7 is a view showing the relationship between the concave portion of the side groove block according to the embodiment shown in FIG. 6 and the vehicle.

  Since the description is basically the same as that according to the second embodiment shown in FIG. 5, the difference will be mainly described.

  In FIG. 7, the parallelogram shape surrounded by the solid line indicates the concave portion of the present invention, and the dotted line indicates the rectangular concave portion.

Since the rectangular side BD indicated by the dotted line is located in a direction orthogonal to the arrow N, the angle α between the side AC of the invention according to this embodiment and the side BD is ∠AO ₁ B, and the side AC is In general, the description is valid for tire approach angles exceeding 10 ° when the vehicle's lateral groove block 17 moves forward in the longitudinal direction and approaches the sidewalk, as described above.

Next, since the rectangular side KI indicated by the dotted line is located in the direction orthogonal to the arrow N, the angle α between the side JH of the invention according to this embodiment and the side KI is ∠JO ₂ K. . The angles θ ₃ and θ ₄ formed by the arrow M and each of the side JH and the side KI are ∠HO ₂ Z and ∠IO ₂ Z, respectively. Since the concave portion of the side groove block according to this embodiment has a parallelogram shape in plan view, θ ₁ = θ ₃ and θ ₂ = θ ₄ are established. Therefore, the side JH is also effective for a tire approach angle that is generally greater than 10 ° when the side groove block 17 of the vehicle deviates in the longitudinal direction and approaches the sidewalk.

  As described above, in the side groove block according to this embodiment, the approach angle of the tire when the vehicle progresses in the longitudinal direction of the side groove block 17 of the vehicle and approaches the sidewalk, which exceeds 10 °. Since there are two sides that are effective in each recess, when the tire of the vehicle comes into contact with the recess of the side groove block according to this embodiment, unique contact sounds and vibrations are further generated.

  FIG. 8 is a schematic perspective view showing a use state of the side groove block according to the fourth embodiment of the present invention.

  Since the description is basically the same as that according to the third embodiment shown in FIG. 6, the difference will be mainly described.

  Referring to the figure, a concave portion 23 arranged at equal intervals in a parallelogram shape in plan view on the upper surface portion 21 of the side groove block 17 and a parallelogram shape connection in plan view connecting between the adjacent concave portions 23. It is comprised from the part 41a and the connection part 41b. As a result, the remaining portion 25 of the upper surface portion 21 is further divided, and there are many dents that come into contact with the tire entering in the direction of the arrow, and more unique contact sounds and vibrations can be expected.

  FIG. 9 is a schematic perspective view showing a use state of the side groove block according to the fifth embodiment of the present invention.

  Since this embodiment is basically the same as that according to the third embodiment shown in FIG. 6, the difference will be mainly described.

  Referring to the figure, the planar parallel sides connecting the recesses 23 arranged at equal intervals in the planogram parallelogram shape on the upper surface portion 21 of the side groove block 17 and the lower positions of the bottom surfaces of the adjacent recesses 23. It is comprised from the connection part 41 of a shape.

  The connecting portion 41 has the same depth as the adjacent concave portion 23 and connects the lower position (the sidewalk side end portion) of the bottom surface portion thereof, and is formed continuously in the longitudinal direction of the side groove block 17. . Therefore, since rainwater or the like generated on the roadway asphalt 29 flows into the connecting portion 41 from the recess 23, a round hole 24 that inserts the connecting portion 41 and the cavity 20 is provided in each of the recesses 23 as shown in FIG. There is no need.

  FIG. 10 is a partial perspective view showing a schematic structure of a side groove block according to a sixth embodiment of the present invention.

  Referring to the drawing, the upper surface portion 21 of the side groove block 17 is not an inclined surface as in the previous embodiments, but a horizontal flat surface. The recess 23 has a rectangular flat plate shape, and an elongated hole 43 that is inserted into the cavity 20 is formed as an opening on the recess 22 side of the flat surface 44. Since the flat surface 44 of the recess 23 is not inclined, the drainage efficiency of rainwater is slightly reduced. However, since a long hole 43 having a large opening area is formed at a position below the rainwater, the rainwater remains in the recess 23. It becomes possible to discharge into the cavity 20 without causing it. The effect of generating contact noise and vibration due to the approach of the vehicle is almost the same as that according to the first embodiment.

  FIG. 11 is a partial perspective view showing a schematic shape of a side groove block according to the seventh embodiment of the present invention, and corresponds to FIG. 10 according to the sixth embodiment.

  Since this side groove block is basically the same as that shown in FIG. 10, the difference will be mainly described.

  Referring to the figure, the shape of recess 23 is different from that of FIG. That is, the lower part of the recess 23 is an inclined surface 46 that is inclined toward the recess 22 side. Since the depth of the recess 23 on the road side is slightly shallow, the contact sound at the start of entry of the vehicle is slightly reduced, but the drainage effect of rainwater flowing into the recess 23 is further improved.

  FIG. 12 is a partial perspective view showing a schematic shape of a side groove block according to the eighth embodiment of the present invention, and corresponds to FIG. 10 according to the sixth embodiment.

  Even in this embodiment, the difference will be mainly described.

  Referring to the drawing, the shape of the recess 23 is different, and the bottom portion is constituted by an inclined surface 47a and an inclined surface 47b which are inclined so as to become lower from the position on the road side and the sidewalk toward the center thereof. . An elongated hole 43 that passes through the cavity 20 is formed as an opening at the center. As a result, the size of the warning sound or the like is about the middle between the sixth embodiment and the seventh embodiment, but the drainage efficiency of rainwater or the like flowing into the recess 23 is maximized.

  In addition, in said 4th Embodiment, although the shape of the connection part is specified, what is necessary is just to have a dent which connects the adjacent recessed part.

  In the fifth embodiment, the concave portion has the same parallelogram shape as that of the third embodiment in plan view. However, the concave portion is a plane according to the first embodiment or the second embodiment. A visual shape may be used.

  Moreover, in said 5th Embodiment, although the shape of the connection part is specified, what is necessary is just to have a dent which connects the downward position in the bottom face of an adjacent recessed part.

  Further, in the second to eighth embodiments, the shape of the concave portion is specified, but one side on the vehicle traveling direction side in the concave portion passes through one end on the sidewalk side, and the side groove block The angle formed by the direction perpendicular to the longitudinal direction and one side may be an acute angle.

  Furthermore, in each of the above-described embodiments, the shape of the concave portion is specified, but other shapes may be used in a plan view, a depth direction, and the like, and the interval between the concave portions may be arbitrarily set.

  Furthermore, in each of the above-described embodiments, the side groove block without a slit is targeted, but the present invention can be similarly applied to a side groove block having a slit. In this case, it is preferable to provide a recess on at least the roadway side of the upper surface portion divided by the slit.

  Furthermore, in each of the above-described embodiments, the opening through which the concave portion and the cavity are inserted is specified, but the number, shape, position, and the like may be arbitrarily set. Moreover, the cross-sectional shape does not necessarily have to expand toward the cavity.

  Furthermore, in each of the above-described embodiments, the trunk body is an integral type including the upper surface portion. For example, the trunk main body includes a gate-type side groove block and a side groove block provided with an upper lid (fixed type, separation type). Can be applied similarly. That is, the side groove block of the present application includes such a side groove block.

  Furthermore, in each of the above-described embodiments, the cross-sectional shape of the cavity formed in the trunk body is specified, but it goes without saying that other cross-sectional shapes such as an oval shape and a rectangular shape may be used.

  Furthermore, in each of the embodiments described above, the pedestrian road boundary block is separate from the side groove block, but can be similarly applied to a side groove block in which these blocks are integrated.
