Description

[Technical field]

[0001] The present invention relates to a car stop block that is provided on the ground of a parking lot or the like to determine a parking position for a vehicle or the like. [Background technology]

[0002] In recent years, due to restrictions on cargo height, there has been an increase in low-bed trucks that ensure a large load capacity by lowering the floor of the loading platform to the ground. Since the body of these low-bed trucks is lowered by reducing the outer diameter of the tires, vibrations from the road surface while driving are relatively easily transmitted to the cargo. Therefore, an increasing number of low-bed trucks are equipped with air suspension (air springs) near the tires of the left, right, front, and rear wheels to suppress vibrations that the loading platform receives from the road surface while driving.

[0003] Providing air suspension provides the following advantages to trucks: Less vibration and a more comfortable ride. In addition, because vibration is less likely to be transmitted to the cargo, the truck is ideal for transporting precision machinery and fresh food. In addition, because the air suspension allows the height of the cargo bed to be adjusted, the work of loading cargo onto the bed can be done more efficiently.

[0004] In a low-floor truck, the air suspension is provided, for example, at a position behind the rear wheel axle of the vehicle so as to protrude downward. Therefore, when a low-floor truck is parked in a parking lot equipped with car stop blocks, the air suspension may come into contact with the car stop block. The contact of the air suspension with the car stop block may cause damage or breakage of the air suspension or the car stop block.

[0005] For example, Patent Document 1 discloses a car stopper in which the surface of a core material made of a rigid body such as concrete or metal is covered with a rubber chip layer made of an elastic body, in order to prevent damage to cars and injuries to people. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Utility Model Application Publication No. 6-43163 Summary of the Invention [Problem to be solved by the invention]

[0007] However, according to the car stopper as disclosed in Patent Document 1, even if a vehicle part such as an air suspension comes into contact with the car stopper, it is believed that the damage or breakage of the air suspension can be suppressed, but the contact between the car stopper and the vehicle part itself is not avoided. Therefore, the car stopper may be damaged or broken, and if the force of the contact with the car stopper is strong, the vehicle part such as the air suspension may be damaged or broken. In addition, the car stopper as disclosed in Patent Document 1 has a double structure made of different materials, which makes the structure complicated and the manufacturing process complicated.

[0008] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a car stopper block which has a simple configuration, can avoid contact with vehicle parts such as air suspension, suppresses scratching and damage to the vehicle parts, and can obtain high rigidity and improve impact resistance in the event of a tire collision. [Means for solving the problem]

[0009] A first aspect of the present invention is a vehicle stop block that is partially buried in the ground and receives the left and right wheels of a vehicle to determine the parking position of the vehicle, comprising: a longitudinal foundation block portion that is at least partially buried in the ground and has a horizontal reference surface; and a main body block portion that is provided above the foundation block portion and protrudes from the reference surface, wherein the main body block portion has wheel stop portions that are provided on both longitudinal sides of the foundation block portion and have wheel receiving surfaces that receive the wheels of the vehicle, and an intermediate block portion that is provided between the wheel stop portions on both longitudinal sides and has a lower height from the reference surface than the wheel stop portions.

[0010] In a second aspect of the present invention, the wheel stopper portion has a first upper surface portion which is a horizontal upper surface portion, and the intermediate block portion has a second upper surface portion which is a horizontal upper surface portion formed at a lower position than the first upper surface portion with respect to the reference plane, and forms a recess together with the wheel stopper portions on both sides in the longitudinal direction.

[0011] In a third aspect of the present invention, the second upper surface portion is provided with a reflecting portion that reflects light.

[0012] In a fourth aspect of the present invention, at least one of the wheel stopper portion and the intermediate block portion, together with the reference surface, forms a drain hole that penetrates in a direction perpendicular to the longitudinal direction in a plan view. Effect of the Invention

[0013] According to the present invention, there is provided a vehicle stopping block that is partially buried in the ground and receives the left and right wheels of a vehicle to determine a parking position of the vehicle, the vehicle stopping block comprising: a longitudinal foundation block portion that is at least partially buried in the ground and has a horizontal reference surface; and a main body block portion that is provided on the upper side of the foundation block portion in a manner protruding from the reference surface, the main body block portion having wheel stopper portions provided on both longitudinal sides of the foundation block portion and having wheel receiving surfaces that receive the wheels of the vehicle; and an intermediate block portion that is provided between the wheel stopper portions on both longitudinal sides and has a lower height from the reference surface than the wheel stopper portions. This simple configuration makes it possible to avoid contact with vehicle parts such as air suspensions, suppress damage and breakage of vehicle parts, and obtain high rigidity, thereby improving impact resistance during tire collisions.

[0015] The present invention aims to prevent contact with vehicle parts when parking a vehicle by devising a shape of a main block part that is provided in a manner protruding above a foundation block part buried in the ground in a car stop block for receiving left and right wheels of a vehicle to determine a parking position of the vehicle, thereby suppressing damage or breakage of the vehicle parts or the block itself. An embodiment of the present invention will be described with reference to the drawings.

[0016] The car stopping block M according to this embodiment will be described with reference to Figs. 1 to 9. Fig. 1 is a perspective view of the car stopping block M. Fig. 2 is a front view of the car stopping block M. Fig. 3 is a plan view of the car stopping block M. Fig. 4 is a left side view of the car stopping block M. Fig. 5 is an end view taken along line AA in Fig. 2 to show the intermediate block portion 30. Fig. 6 is a cross-sectional view taken along line BB in Fig. 2 to show the drainage holes 26, 39. Fig. 7 is a cross-sectional view taken along line DD in Fig. 2 to show the reflector plate 28. Fig. 8 is a perspective view showing the car stopping block M installed on the ground G. Fig. 9 is a view showing the state in which the wheel t of a vehicle (truck T) is in contact with the car stopping block M cut along line CC in Fig. 2. In explaining this embodiment, the left-right direction in Fig. 3 is the left-right direction of the car stopping block M, and the up-down direction in Fig. 3 is the front-rear direction of the car stopping block M. Also, in Fig. 9, for convenience, only the cross section of the intermediate block portion 30 of the car stopping block M is shown.

[0017] The vehicle in this embodiment is a large, low-bed truck T in which the floor surface of the loading platform is formed low by reducing the outer diameter of the wheels t, as shown in Fig. 9. The low-bed truck T has an air suspension (air spring) C as a vehicle component between the left and right wheels t, t at the rear of the truck T and in the vicinity of the left and right wheels t, t. The air suspension C is provided between the left and right wheels t, t in the middle in the vehicle width direction so as to protrude downward from the floor of the vehicle.

[0018] The car stop block M is installed with a part buried in the ground, and is for receiving the left and right wheels of a vehicle to determine the parking position of the vehicle. As shown in FIG. 1, the car stop block M comprises a foundation block part 1 at least a part of which is buried in the ground when installed on the ground, and a main body block part 2 provided in a manner protruding above the foundation block part 1. The car stop block M is configured as a linear elongated block with the left-right direction as the longitudinal direction as a whole. Moreover, the car stop block M is configured as a symmetrical or approximately symmetrical in each of the left-right direction and the front-rear direction as a whole.

[0019] As shown in Figures 2 and 3, the foundation block part 1 is a longitudinal block part having a horizontal reference surface 10 on its upper surface. The foundation block part 1 has four side surfaces 11 extending downward from the peripheral portion of the reference surface 10, and a bottom surface part 12 provided on the opposite side to the reference surface 10 and parallel to the reference surface 10. The foundation block part 1 is formed by the reference surface 10, the side surfaces 11, and the bottom surface part 12 into an elongated, approximately truncated quadrangular pyramid shape with the top side of the pyramid and the left-right direction as the longitudinal direction.

[0020] 2 and 4, the four side surface portions 11 are formed so as to have the same inclination angle α with respect to the vertical plane. In this embodiment, the inclination angle α is set to, for example, approximately 8°. However, the magnitude of the inclination angle α is not limited.

[0021] In addition, the foundation block portion 1 has chamfered corners at the corners formed by the reference surface 10 and each of the four side surface portions 11, the corners formed by the bottom surface portion 12 and each of the four side surface portions 11, and the corners formed by adjacent side surface portions 11. That is, in the foundation block portion 1, all of the corners (ridge lines) formed by adjacent surface portions are chamfered (rounded).

[0022] A car stop block M equipped with the foundation block portion 1 configured in this manner is installed with the entire or nearly entire foundation block portion 1 buried in the ground, as shown in Fig. 8. In the example shown in Fig. 8, the car stop block M is installed with the reference surface 10 of the foundation block portion 1 nearly flush with the ground surface G, and the entire main body block portion 2 protrudes from the ground surface G.

[0023] As shown in Fig. 2, the main body block part 2 is a block part provided in a manner protruding upward from a reference surface 10 constituting the upper surface part of the foundation block part 1. The main body block part 2 protrudes in a stepped manner from the upper surface part of the foundation block part 1 except for the peripheral part so that the reference surface 10 is formed so as to be continuous all around along the rectangular outer shape of the foundation block part 1 in a plan view. Therefore, the reference surface 10 has, as its area parts, front and rear long side parts formed over the entire longitudinal direction of the foundation block part 1 and left and right short side parts formed over the entire lateral direction of the foundation block part 1.

[0024] The main body block portion 2 is provided integrally with the foundation block portion 1. In other words, the main body block portion 2 constitutes an integral block body together with the foundation block portion 1 in the car stopper block M. This block body has a symmetrical or approximately symmetrical shape in the left-right direction. The main body block portion 2 has wheel stopper portions 20 provided on both sides in the longitudinal direction of the foundation block portion 1, and an intermediate block portion 30 provided between the wheel stopper portions 20 on both sides in the longitudinal direction.

[0025] The wheel stopper portions 20 on both the left and right sides are block portions that receive the left and right wheels of a vehicle. The wheel stopper portions 20 have first upper surface portions 21 that are horizontal upper surface portions on both the left and right sides of the main block portion 2. The wheel stopper portions 20 are protruding portions that follow the outer shape of a substantially rectangular parallelepiped, and have the following surface portions that form the outer shape: the first upper surface portion 21, the wheel receiving surface 22 that is the front surface of the wheel stopper portion 20, the outer inclined surface portion 23 that is the outer side surface portion in the left-right direction, the inner inclined surface portion 24 that is the inner side surface portion in the left-right direction, and the rear inclined surface portion 25 that is the rear surface side surface of the wheel stopper portion 20. The wheel stopper portion 20 is formed into an approximately quadrangular pyramid shape by the first upper surface portion 21, the wheel receiving surface 22, the outer inclined surface portion 23, the inner inclined surface portion 24, and the rear inclined surface portion 25, with the upper side being the apex side of the quadrangular pyramid, the left-right direction being the long side direction, and the front-rear direction being the short side direction.

[0026] The first upper surface portion 21 is provided parallel to the reference surface 10 of the foundation block portion 1. The first upper surface portion 21 is connected to each of the front, rear, left and right inclined surfaces of the wheel stopper portion 20, including the wheel receiving surface 22, via curved surface portions forming an arc shape. Furthermore, in the wheel stopper portion 20, adjacent inclined surface portions are connected to each other via curved surface portions forming an arc shape. That is, in the wheel stopper portion 20, the corner portions (ridge portions) formed by adjacent surface portions are all rounded portions formed by curved surfaces.

[0027] As shown in Fig. 2 and Fig. 4, the wheel receiving surface 22 is formed to be slightly inclined backward in the vertical direction from the reference surface 10 of the foundation block portion 1 to the first upper surface portion 21. In this embodiment, the inclination angle β of the wheel receiving surface 22 with respect to the vertical plane is set to, for example, about 8° similar to the inclination angle α. However, the magnitude of the inclination angle β is not limited. The magnitude of the inclination angle β is set, for example, according to the height H of the main body block portion 2 from the reference surface 10, etc., so that the wheels of the vehicle do not easily go over the wheel stopper portion 20.

[0028] 2, in the wheel stopper portion 20, the outer inclined surface portion 23 is formed to be inclined from the left and right outer side toward the inside in the up-down direction from the reference surface 10 of the foundation block portion 1 to the first upper surface portion 21. In this embodiment, the inclination angle γ of the outer inclined surface portion 23 with respect to the vertical plane is set to, for example, about 16°, which is about twice the inclination angle β of the wheel receiving surface 22. However, the magnitude of the inclination angle γ is not limited.

[0029] 2, the inner inclined surface portion 24 is formed in an inclined shape from the left-right inner side toward the outer side from the second upper surface portion 31 to the first upper surface portion 21 of the intermediate block portion 30 described later. In this embodiment, the inclination angle of the inner inclined surface portion 24 with respect to the vertical plane is set to the same inclination angle γ as that of the outer inclined surface portion 23.

[0030] 3 and 4, the rear inclined surface portion 25 is formed to be slightly inclined forward from the reference surface 10 of the foundation block portion 1 to the first upper surface portion 21. In this embodiment, the rear inclined surface portion 25 is formed as an inclined surface that is symmetrical with the wheel receiving surface 22 in the front-rear direction. However, the rear inclined surface portion 25 does not have to be symmetrical with the wheel receiving surface 22 in the front-rear direction.

[0031] The intermediate block portion 30 is a portion between the left and right wheel stopper portions 20 in the main body block portion 2, and is a block portion having a lower height from the reference plane 10 than the wheel stopper portions 20. As shown in Figs. 2, 3, and 5, the intermediate block portion 30 is provided between the left and right wheel stopper portions 20 in a manner protruding upward from the reference plane 10 of the foundation block portion 1. The intermediate block portion 30 has a second upper surface portion 31 which is a horizontal upper surface portion that is an upper surface portion of the left and right intermediate portion of the main body block portion 2. The intermediate block portion 30 is a protruding portion that has approximately the same dimensions as the wheel stopper portions 20 in the front-rear direction and follows an approximately rectangular parallelepiped outer shape, and has the second upper surface portion 31, a front surface portion 33 which is a surface portion on the front side of the intermediate block portion 30, and a back surface portion 32 which is a surface portion on the rear side of the intermediate block portion 30 as surface portions that form the outer shape. The intermediate block portion 30 is connected to the wheel stopper portions 20 on both the left and right sides, respectively, and forms an integral main body block portion 2 together with the left and right wheel stopper portions 20.

[0032] The second upper surface portion 31 is formed at a lower position than the first upper surface portion 21 with respect to the reference surface 10. That is, as shown in FIG. 2, the second upper surface portion 31 is formed to be substantially parallel to the reference surface 10 of the foundation block portion 1 and lower than the first upper surface portion 21. In this embodiment, the height h of the second upper surface portion 31 with respect to the reference surface 10 is formed to be substantially half the height H of the first upper surface portion 21 with respect to the reference surface 10. That is, the height h and the height H have a relationship of h=1 / 2H. However, the height h of the second upper surface portion 31 may be lower than the height H of the first upper surface portion 21, and the ratio of the sizes of these heights is not limited. In addition, the height H of the first upper surface portion 21 is set to be lower than the height of a general ready-made product with respect to the ground G and to be able to firmly receive the tire in order to correspond to the low-floor truck T.

[0033] The front portion 33 and the back portion 32 are each formed as an inclined surface portion that forms a certain inclination angle with respect to the vertical plane from the reference surface 10 to the second upper surface portion 31 of the foundation block portion 1. In this embodiment, the front portion 33 and the back portion 32 of the intermediate block portion 30 are formed so as to overlap the wheel receiving surface 22 and the rear inclined surface portion 25 of the wheel stopper portion 20, respectively, in a side view, and are inclined at the same angle as the inclination angle β of these surfaces.

[0034] The intermediate block portion 30 forms a recess 37 in the main body block portion 2 together with the wheel stopper portions 20 on both sides in the longitudinal direction of the foundation block portion 1. The recess 37 is formed by the second upper surface portion 31 of the intermediate block portion 30 and the inner inclined surface portions 24 of the left and right wheel stopper portions 20. That is, the main body block portion 2 forms a recessed step portion in the middle portion in the longitudinal direction by lowering the second upper surface portion 31 of the intermediate block portion 30 relative to the first upper surface portions 21 of the wheel stopper portions 20 on both the left and right sides. In this embodiment, the range of the intermediate block portion 30, i.e., the range of the recess 37, is approximately 1 / 3 of the middle portion of the entire car stopper block M in the longitudinal direction of the car stopper block M.

[0035] In this configuration in which the recess 37 is formed in the main body block portion 2, the inclination angle γ of the inner inclined surface portion 24 of the left and right wheel stopper portions 20 is formed to be large, so that the degree of expansion of the left and right dimension of the recess 37 from the bottom to the top can be increased.

[0036] In the intermediate block portion 30, a reflecting portion 35 that reflects light is provided in the center of the second upper surface portion 31. The reflecting portion 35 has a configuration in which a circular reflecting plate 35b is fitted and fixed in a reflecting plate fixing recess 35a that is recessed in a circular shape in the second upper surface portion 31.

[0037] The reflector 35b has an outer shape of a generally dome shape or a flat truncated cone shape that is convex upward, and has an outer diameter that is generally the same as the inner diameter of the reflector fixing recess 35a in a plan view. The reflector 35b is, for example, a corner cube reflector that reflects irradiated light in the direction of incidence, that is, has a so-called retroreflective characteristic. The reflector 35b is fixed to the reflector fixing recess 35a with most of its upper side protruding from the second upper surface portion 31. The method of fixing the reflector 35b to the intermediate block portion 30 may be any method, such as adhesive, double-sided tape, or screws, as long as the reflector 35b does not easily come off.

[0038] A central groove 34 is formed in the center of the intermediate block 30 in the left-right direction. The central groove 34 is formed over the entire second upper surface 31, the back surface 32, and the front surface 33, except for the portion where the reflector fixing recess 35a is formed, so as to extend along a plane perpendicular to the left-right direction. That is, the central groove 34 is formed so as to connect to both the front and rear sides of the reflector fixing recess 35a in the second upper surface 31, and has grooves 32c, 33c formed in the back surface 32 and the front surface 33, respectively. The central groove 34 is formed to the same or approximately the same depth as the reflector fixing recess 35a in the second upper surface 31.

[0039] In addition, at the boundaries between the intermediate block portion 30 and the left and right wheel stopper portions 20, boundary groove portions 36 are formed, which are groove portions formed along a surface perpendicular to the left-right direction, similar to the central groove portion 34. The boundary groove portion 36 has portions formed along each of the surfaces of the second upper surface portion 31, the back surface portion 32 and the front surface portion 33.

[0040] Further, a reflector 28 is attached to the wheel receiving surface 22 side of each of the left and right wheel stopper portions 20. The reflector 28 is provided on the wheel receiving surface 22 of each of the wheel stopper portions 20 at a position closer to the outside than the center position in the left-right direction.

[0041] The reflector 28 has a rectangular outer shape and is fixed to the wheel stopper 20 in a manner of being fitted into a rectangular reflector fixing recess 27 formed in the wheel receiving surface 22. The reflector fixing recess 27 is formed as a substantially square recess corresponding to the outer shape of the reflector 28 in a front view, and is horizontally recessed from the wheel receiving surface 22 toward the rear. As shown in FIG. 7, the reflector fixing recess 27 is formed in a substantially U-shape with the lower side longer than the upper side in a side cross-sectional view. The reflector 28 is attached so as to contact the rear surface of the reflector fixing recess 27. The reflector 28 may be fixed to the wheel stopper 20 by any means, such as adhesive, double-sided tape, or screws, as long as the reflector 28 does not easily come off.

[0042] The reflector 28 is formed in substantially the same shape as the reflector fixing recess 27 in a front view, and in this embodiment, is formed in a substantially rectangular shape. The reflector 28 is provided so that, when attached to the reflector fixing recess 27, its surface is positioned at a position set back from the wheel receiving surface 22. In other words, when the reflector 28 is installed in the reflector fixing recess 27, the reflector 28 is provided so as not to protrude from the wheel receiving surface 22 (see FIG. 7). The reflector 28 is formed, for example, of a corner cube reflector having retroreflective properties.

[0043] Furthermore, in the car stopper block M according to this embodiment, each portion of the wheel stopper portion 20 and the intermediate block portion 30, together with the reference surface 10, forms drainage holes 26, 39 penetrating in a direction perpendicular to the longitudinal direction (front-rear direction) in a plan view. The drainage hole 26 in each wheel stopper portion 20 is formed in the center in the left-right direction. Furthermore, the drainage holes 39 in the intermediate block portion 30 are formed in two places on both the left and right sides.

[0044] The drain hole 26 at the portion where the wheel stopper portion 20 is formed is formed as a substantially linear through-hole portion along the front-rear direction, with the front side opening toward the wheel receiving surface 22 and the rear side opening toward the rear inclined surface portion 25. The wheel stopper portion 20 has a groove portion which, together with the reference surface 10, forms the drain hole 26. This groove portion penetrates in the front-rear direction and is formed by a concave surface that forms an inverted "U" shape when viewed from the front. The drain hole 26 is formed as a tunnel-shaped through-hole portion with the lower surface being the reference surface 10 by the groove portion formed on the wheel stopper portion 20 side.

[0045] 2 and 6, the drainage hole 26 is formed so that the opening area of ​​the opening 26b on the rear inclined surface portion 25 side is larger than the opening area of ​​the opening 26a on the wheel receiving surface 22 side. The drainage hole 26 is formed so that the flow path area through which water flows gradually increases from the front opening 26a to the rear opening 26b. In other words, the drainage hole 26 is formed in a tapered shape with the width dimension (dimension in the left-right direction) gradually narrowing from the rear side to the front side.

[0046] The drain hole 39 in the formation portion of the intermediate block portion 30 is formed as a portion having the same shape as the drain hole 26 of the wheel stopper portion 20. That is, the intermediate block portion 30 has a groove portion formed by a concave surface which forms the drain hole 39 together with the reference surface 10, and the drain hole 39 is formed as a tunnel-shaped through portion with the lower surface being the reference surface 10 by the groove portion formed on the intermediate block portion 30 side. The drain hole 39 is formed so that the flow path area through which water flows gradually increases from the front opening 39a to the rear opening 39b.

[0047] As described above, the drainage holes 26, 39 formed in a total of four locations in the wheel stop block M are arranged at approximately equal intervals in the left-right direction. In other words, as shown in FIG. 2, the drainage holes 39 of the intermediate block portion 30 are provided at positions that divide the interval R between the drainage holes 26, 26 of the left and right wheel stop portions 20 into approximately three equal parts. In other words, the interval r between adjacent drainage holes 26, 39 in the left-right direction is 1 / 3 the length of the interval R. Note that, in this embodiment, the drainage holes 26, 39 are provided in the formation portions of both the wheel stop portion 20 and the intermediate block portion 30, but it is sufficient that the drainage holes are provided in the formation portions of at least one of the wheel stop portion 20 and the intermediate block portion 30.

[0048] The car stopping block M of this embodiment having the above-mentioned configuration has the following effects: That is, the car stopping block M has a simple configuration that can avoid contact with vehicle parts such as the air suspension C, suppress scratching and damage to the vehicle parts, and obtain high rigidity, thereby improving impact resistance in the event of a tire collision.

[0049] In the car stopping block M, the main body block portion 2 formed on the foundation block portion 1 has wheel stopping portions 20 provided on both longitudinal sides of the foundation block portion 1 and having wheel receiving surfaces 22 for receiving wheels t of a vehicle (truck T), and an intermediate block portion 30 provided between the wheel stopping portions 20 on both longitudinal sides and lower in height from the reference plane 10 than the wheel stopping portions 20. In other words, the car stopping block M has a configuration in which the portions that are not hit by the tires and where downward-protruding vehicle parts such as the air suspension C are located are relatively lower in the left-right direction.

[0050] 9, when a truck T is parked against a car stop block M installed in a parking lot with its wheels t in contact with the wheel receiving surface 22, the air suspension C located between the left and right rear wheels t, t in the vehicle width direction is located above the intermediate block portion 30, that is, in the recess 37. This can reduce the risk of the air suspension C also coming into contact with the main body block portion 2 of the car stop block M as much as possible, thereby suppressing damage or breakage to the vehicle parts of the truck T parked using the car stop block M and the car stop block M.

[0051] Therefore, with the car stopping block M, for example, a driver of a low-floor large truck can park the vehicle in a parking lot with peace of mind by backing up to the position of the car stopping block M, that is, to a position where the rear wheels come into contact with the wheel receiving surface 22 of the car stopping block M. This prevents the vehicle from protruding out of the parking space designated for the vehicle in the parking lot, realizing an orderly parking state of the vehicle in the parking lot and contributing to improving safety. Note that examples of vehicle parts that protrude downward and are provided on the rear bottom side of the vehicle include the arm of the air suspension C, rear lifting equipment such as a gate lift, and a tool box provided at the rear of the vehicle.

[0052] Moreover, the car stop block M is configured as an integrated block with a foundation, including a foundation block portion 1 and a main body block portion 2. This configuration allows for a simple configuration of an integrated block body, and also provides high rigidity and resistance to impacts during tire collisions, in comparison with a car stopper in which blocks are provided at two locations spaced apart in the left-right direction, corresponding to the left and right wheels, for example.

[0053] Furthermore, for example, even if the wheels t of the truck T come into contact with the body block part 2 during parking, the body block part 2 will not move independently of the foundation block part 1. This makes it possible to minimize the risk of the body block part 2 moving and coming into contact with vehicle parts when the wheels t of the truck T collide with the body block part 2.

[0054] Moreover, the wheel stopper portion 20 has a first upper surface portion 21 which is a horizontal upper surface portion, and the intermediate block portion 30 has a second upper surface portion 31 which is a horizontal upper surface portion formed at a position lower than the first upper surface portion 21 with respect to the reference plane 10, and forms a recess 37 together with the wheel stopper portions 20 on both sides in the longitudinal direction. According to this configuration, when the wheel t is received by the wheel receiving surface 22 of the wheel stopper portion 20, the air suspension C provided between the left and right wheels t, t can be positioned in the recess 37, so that contact between the vehicle parts such as the air suspension C and the car stopper block M can be avoided, and the bottom of the truck T, the vehicle parts, and the car stopper block M can be prevented from being scratched or damaged.

[0055] In addition, the second upper surface portion 31 is provided with a reflecting portion 35 that reflects light. According to this configuration, when the truck T is parked in reverse, the position of the recessed portion 37 that can avoid interference between the bottom of the truck T or vehicle parts and the car stop block M can be easily seen by, for example, a rearward confirmation camera or the like provided at the rear of the truck T, and the position of the truck T in the vehicle width direction relative to the car stop block M can be easily adjusted. This makes it easier to position the rear bottom of the truck T and the air suspension C, etc. above the intermediate block portion 30 of the main body block portion 2, and effectively avoids contact between the vehicle parts of the truck T and the car stop block M. In particular, according to the configuration in which a circular reflector 35b is provided in the reflecting portion 35, light from any angle of 360° can be reflected, so that good visibility can be obtained for the reflecting portion 35.

[0056] In addition, at least one of the wheel stopper portion 20 and the intermediate block portion 30 forms drain holes 26, 39 penetrating in a direction perpendicular to the longitudinal direction in a plan view together with the reference surface 10. With this configuration, it is possible to prevent water from accumulating near the wheel stopper block M.

[0057] Furthermore, the car stop block M described in this embodiment is formed by integrally forming the foundation block portion 1 and the main body block portion 2, and is installed with the foundation block portion 1 buried in the ground G. With this configuration, no bolts are required to fasten the block body to the ground G, so pins such as bolts are not exposed from the ground G and do not damage the tires or vehicle of the truck T that is being parked, allowing the truck to be parked safely.

[0058] Although one embodiment of the present invention has been described, the above description is merely an example of the present invention, and the present invention is not limited to the above-described embodiment. Therefore, even if the embodiment is different from the above-described embodiment, various modifications can be made depending on the design, etc., as long as they do not deviate from the technical concept of the present invention.
