Description

[Technical field]

[0001] The present invention relates to a synthetic resin car stopper that is installed mainly in outdoor parking lots of shopping centers and other mass retailers, as well as amusement facilities and factories. [Background technology]

[0002] This type of car stopper is disclosed in Patent Documents 1 and 2, and both are considered to be publicly known technologies similar to the present invention in that the car stopper body is molded from synthetic resin with a hollow interior and emits light forward, making it possible to notify people of the presence and position of the car stopper even at night. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 3692336 [Patent Document 2] Patent No. 2899791 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the car stopper described in Patent Document 1, a phosphorescent paint is applied (a phosphorescent layer is formed) to the back surface of the transparent side wall (light-emitting component) (5) made of acrylic resin or polycarbonate resin, and the light accumulated in the phosphorescent layer by exposure to sunlight during the day is released at night. Therefore, in rainy or cloudy weather, the phosphorescence efficiency is poor, and a long light emission time cannot be ensured.

[0005] In addition, the transparent side wall (light-emitting member) (5) having a phosphorescent layer formed on its back surface is a separate body from the car stopper main body (3) which is molded from polypropylene or polyethylene. Therefore, the car stopper main body (3) and the transparent side wall (light-emitting member) (5) must be molded using separate molding dies and resin materials, resulting in high manufacturing costs.

[0006] Furthermore, the multiple legs (7) provided on the peripheral portion of the transparent side wall (light-emitting member) (5) are inserted from the outside into fitting holes (9) formed corresponding to the peripheral portion of the recess (11) in the car stop body (3). Since the transparent side wall (light-emitting member) (5) is exposed from the outer surface of the car stop body (3), there is a risk that the transparent side wall (light-emitting member) (5) may be forcibly removed from the outside or that rainwater may seep in through the fitting portion, and as a result of being inevitably subjected to adverse effects from natural phenomena, the stability in use is inferior.

[0007] Furthermore, the car stopper body (3) is injection molded from polypropylene or polyethylene into a trapezoidal side cross section, but the surrounding wall surface of the hollow interior that opens downward is a simple plate of uniform thickness overall, so it has poor impact resistance and may easily be damaged when subjected to impact from a vehicle, etc.

[0008] Moreover, Patent Document 1 does not provide any specific description of the means for installing the car stopper body (3) made of synthetic resin in a parking lot. As described above, the surrounding wall surface and the ground bearing surface of the car stopper body (3) are simple plates of uniform thickness overall, and this, combined with the fact that the interior is hollow, makes it impossible to maintain a durable and rigid installation state in the parking lot.

[0009] On the other hand, in the synthetic resin car stopper described in Patent Document 2, when a new concrete floor surface of a parking lot is constructed, two special legs (3) are screwed into corresponding screw holes (2e) in the car stopper body (2) and the legs (3) are embedded and integrated into the concrete floor surface. This means that it is inconvenient that the car stopper cannot be installed in a desired position on the concrete road surface of an existing parking lot as a so-called retrofit method.

[0010] In addition, a reflector (2c) is integrally molded on the top surface (2b) or the slope (2a) of the car stop body (2), and the light reflected by the reflector (2c) when it receives light from vehicles entering the parking lot at night is used to indicate the location of the car stop. However, there is no description that the car stop body (2) is molded from a transparent (light-transmitting) synthetic resin, and furthermore, since the reflector (2c) is only partially formed on the top surface (2b) or the slope (2a), the range of the reflected light from this is narrow, and it is difficult to clearly see the location of the car stop from a distance at night or when it is raining, so it must be said that the function and effectiveness of the device is inferior. [Means for solving the problem]

[0011] The present invention aims to improve these problems, and in order to achieve this aim, claim 1 provides a car stopper body integrally molded from a colored transparent polycarbonate resin into a rectangular shape extending in the left and right lateral directions when viewed from the top and bottom, and into a hollow, approximately trapezoidal shape with a downward opening in the side cross section;

[0012] and a hard synthetic resin bottom plate attached to the underside of the opening of the car stopper body in a covered state.

[0013] The waist wall that stands continuously and integrally at a certain height from the periphery of the base plate is surrounded by the front and rear walls and the left and right side walls of the car stopper body. death,

[0014] The entire inside of the inclined front wall surface, which serves as the wheel receiving surface of the car stopper body, is shaped as a light reflecting surface consisting of a diamond cut surface or other uneven rough surface,

[0015] A plurality of LEDs that emit light toward the light reflecting surface of the front wall are installed side by side at a mid-height position of the rear wall of the car stopper body,

[0016] A battery or solar cell of a battery-type solar panel housed in a recess recessed from the center of the top wall surface of the car stop body is electrically connected and wired to the plurality of LEDs powered by the battery or solar cell,

[0017] At the corners where the top wall surface of the car stopper body intersect with the left and right side walls, a mounting groove is formed in a cut-out state, which recesses a certain depth from the top wall surface to approximately the mid-height position of each side wall surface and opens sideways in a substantially semi-cylindrical or bilaterally symmetrical substantially L-shaped cross section,

[0018] The structure is characterized in that it is designed to be attached and fixed to the surface of the parking lot by means of anchor bolt receiving tubes that hang continuously and integrally from the bottom surface of each mounting groove to approximately the lower half of the bottom plate, and anchor bolts that penetrate the bottom plate and / or adhesive for the bottom plate.

[0019] In claim 2, a plurality of parallel vertical reinforcing ribs are continuously and integrally extended inward by a certain amount from the top wall surface and the front and rear wall surfaces of the car stopper body, and an inverted U-shaped wiring receiving tunnel is cut out at the lower end of the vertical reinforcing rib extending only from the rear wall surface.

[0020] The same plurality of rib support bosses for receiving the vertical reinforcing ribs of the car stopper body are formed by continuously extending upward from the upper end of the waist wall that rises a certain height from the rear wall portion of the base plate, and the wiring receiving tunnels of the vertical reinforcing ribs are kept covered from below by the respective rib support bosses,

[0021] A characteristic of this device is that electrical connection wiring between the multiple LEDs and their rechargeable battery is passed almost horizontally through the wiring receiving tunnels, which are all located at the same height in the multiple vertical reinforcing ribs.

[0022] A third aspect of the present invention is characterized in that a plurality of LEDs are interposed between adjacent parallel vertical reinforcing ribs.

[0023] In claim 4, a plurality of drainage holes are cut out in a scattered manner in a waist wall that rises continuously and integrally from the periphery of the bottom plate to a certain height,

[0024] The car stopper body is characterized in that the lower end receiving concave step surface of the anchor bolt receiving tube is formed to correspond to the left and right wall portions of the waist wall.

[0025] Claim 5 is characterized in that the wall thicknesses of the top wall, front and rear wall, and left and right wall surrounding the approximately trapezoidal hollow interior of the car stopper body are all set to approximately uniform dimensions of about 3.5 to 4.5 mm. Effect of the Invention

[0026] According to the above configuration of claim 1, a bottom plate is attached in a covered state to the underside of the opening of the hollow, approximately trapezoidal car stopper body, and a pair of left and right anchor bolt receiving tubes are erected on the car stopper body, and anchor bolt receiving holes that match and communicate with the anchor bolt receiving tubes are formed in the bottom plate corresponding to the above-mentioned bottom plate.Therefore, by using either or both of an anchor bolt (preferably a hole-in anchor) that passes through both of them, and a road surface adhesive (preferably an epoxy resin-based adhesive for concrete) that is applied to the underside of the bottom plate, the car stopper can be firmly retrofitted to the road surface made of concrete, asphalt, etc. of an existing parking lot, which is extremely convenient.

[0027] In addition, despite being lightweight as a synthetic resin car stopper, the pair of left and right anchor bolt receiving tubes not only serve to reinforce the lower half of the car stopper body, but the waist wall that rises a certain height from the bottom plate functions as an inner wall that reinforces the front, rear and left and right side walls of the car stopper body which is fitted into it in a surrounding state. Combined with the fact that the car stopper body is a one-piece molded product made of impact-resistant polycarbonate resin, a highly rigid assembly with the bottom plate is obtained, and even if it is repeatedly subjected to impacts and loads from vehicles, etc., there is no risk of it being improperly deformed or even damaged.

[0028] Furthermore, the main body of the car stopper is molded as a single unit from colored transparent polycarbonate resin, and the entire inside (back side) of the front wall, which forms the inclined wheel-receiving surface that is approximately trapezoidal in cross section, is shaped as a light-reflecting surface made of diamond-cut surfaces and other uneven and rough surfaces. Due to this light-diffusing lens (diffuse reflection) action and the high light transmission performance of the particularly transparent polycarbonate resin, not only can the driver of the vehicle clearly see the location of the car stopper through the backup camera as well as the side mirror when backing into a parking space, but pedestrians in a large outdoor parking lot can also easily see the location of the car stopper from a distance at night or when it is raining, and there is no risk of an accident such as a pedestrian tripping over the car stopper and falling.

[0029] In particular, multiple LEDs (light-emitting diodes) are installed side-by-side at a mid-height position on the rear wall of the car stop body, and light is emitted from the multiple LEDs toward the entire inside of the front wall on which the light-reflecting surface is shaped. Combined with the light transmittance of the transparent polycarbonate resin, the light emitted from the LEDs can be emitted with extremely high illuminance in all directions, not only from the front wall of the car stop body, but also from the top wall, rear wall, and left and right wall.As a night-time lighting fixture that replaces street lights in vast outdoor parking lots with numerous car stoppers, the location of the car stoppers can be clearly seen from a distance, not only by drivers of parked vehicles but also by pedestrians.As a result, the device is extremely useful for vast outdoor parking lots at mass retailers, amusement facilities, and other locations where there are many pedestrians even at night.

[0030] In that case, if the configuration of claim 2 is adopted, a plurality of vertical reinforcing ribs that continuously protrude inward by a certain amount from the rear wall surface of the car stop body, and a plurality of the same rib support bosses that rise continuously upward by a certain height from the waist wall of the bottom plate that functions as the reinforcing inner wall of the car stop body, can be used to pass the electrical connection wiring between a plurality of LEDs (light emitting diodes) and the battery that powers them almost horizontally into the wiring receiving tunnel cut out at the lower end of the vertical reinforcing ribs, which is covered from below by the upper end of the rib support boss, thereby achieving the effect of reliably and stably laying the connection wiring inside the hollow interior of the car stop body.

[0031] Furthermore, if the configuration of claim 3 is adopted, since multiple of the above-mentioned LEDs are interposed between adjacent vertical reinforcing ribs which are arranged in parallel, the light emitted from the LEDs can be irradiated evenly and efficiently toward the front wall surface on which the light-reflecting surface is shaped.

[0032] Furthermore, if the configuration of claim 4 is adopted, rainwater and other moisture that has infiltrated into the hollow interior of the car stopper body can be drained to the outside through the multiple drainage holes cut into the waist wall of the bottom plate, and the receiving concave step surfaces formed on the left and right wall portions of the waist wall stably receive the lower end of the anchor bolt receiving tube in the car stopper body, thereby maintaining an even more rigid assembled state between the car stopper body and its bottom plate.

[0033] Furthermore, if the configuration of claim 5 is adopted, the wall thickness dimension constituting the main body of the car stopper is considerably thicker than that of conventional synthetic resin car stops, and this, combined with the polycarbonate resin material in particular, has the effect of providing excellent impact resistance and durability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0035] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Figures 1 to 13 show a car stopper (A) made of synthetic resin according to the embodiment, and (10) is the car stopper body, which is a rectangular shape extending elongatedly in the left and right lateral directions when viewed from the top and bottom, and has a hollow, approximately trapezoidal shape with a downward opening in side cross section, and is injection molded as a whole from transparent polycarbonate resin colored in orange, green, fluorescent color, or other suitable color.

[0036] In other words, the car stopper body (10) is a one-piece molded product made of the transparent polycarbonate resin, and has a flat top wall surface (11) on the surface, a front wall surface (12F) which serves as the wheel receiving surface and has a gentle inclination angle (the intersection angle with the ground contact surface is a relatively small acute angle, preferably 50 degrees) (α), a rear wall surface (12R) which has a steeper inclination angle (the intersection angle with the ground contact surface is a relatively large acute angle, preferably 85 degrees) (β) than the front wall surface (12F) or is nearly vertical (the intersection angle with the ground contact surface is nearly a right angle), and left and right wall surfaces (13L) (13R) which have nearly the same steep inclination angle as the rear wall surface (12R), and a edging flange (14) protrudes outward continuously and integrally from the peripheral edge of the car stopper body (10).

[0037] Moreover, the wall thickness (T) of the wall surfaces (11), (12F), (12R), (13L), (13R) surrounding the hollow interior (S) of the car stopper body (10), including the protrusion amount of the edging flange (14), is set to a uniform dimension of 3.5 to 4.5 mm, preferably about 4 mm, which, combined with the polycarbonate resin material used, enables the car stopper to exhibit excellent properties such as impact resistance, durability, high heat resistance, and other properties.

[0038] Incidentally, in the illustrated first embodiment, as a preferred example, the long side (length dimension) (Y) of the rectangular car stopper body (10) when viewed from the top and bottom is set to 550 mm, the short side (width dimension) (X) is set to 160 mm, the width dimension (W) of the flat top wall surface (11) is set to 80.5 mm, and the height (H) is set to 100 mm.

[0039] As is clear from Figures 10 to 13, in the hollow interior (S) opening downward of the car stopper body (10) which is integrally molded into a substantially trapezoidal shape in side cross section, a plurality of (two rows in the illustrated example) long horizontal reinforcing ribs (15) extending parallel to the long side (Y) forming a rectangle in plan and bottom view protrude inwardly and continuously by a certain amount (Z) (preferably 10 mm or less) from the top wall surface (11) and the left and right wall surfaces (13L) and (13R), while a plurality of (five rows in the illustrated example) short vertical reinforcing ribs (16) extending parallel to the short side (X) also forming a rectangle protrude inwardly and continuously by the same certain amount (Z) from the top wall surface (11) and the front and rear wall surfaces (12F) and (12R), and the vertical reinforcing ribs (16) and the horizontal reinforcing ribs (15) are arranged in a lattice pattern in bottom view.

[0040] In this case, among the vertical reinforcing ribs (16) that continuously protrude inward by a certain amount (Z) from the top wall surface (11) and the front and rear wall surfaces (12F) (12R), the vertical reinforcing rib (16) that protrudes along the rear wall surface (12R) in particular has an inverted U-shaped wiring receiving tunnel (17) cut out at its lower end as shown in Figures 10 and 13, so that the electrical wiring described below can be passed through it in a substantially horizontal, cross-sectional state.

[0041] At the corners where the top wall surface (11) of the car stopper body (10) intersects with the left and right wall surfaces (13L, 13R), mounting grooves (18L, 18R) are recessed by a certain depth (D) (preferably about half the back height) from the flat top wall surface (11) to a mid-height position of each side wall surface (13L, 13R), and are shaped as, so to speak, cut-outs having a substantially semi-cylindrical or L-shaped cross section that opens sideways as shown in Figures 1, 2, 5 and 10-12.

[0042] (19L) (19R) are anchor bolt receiving tubes that hang down continuously and integrally from the flat groove bottom surfaces (20L) (20R) of the respective mounting grooves (18L) (18R) to the underside of the opening in the car stopper body (10) in approximately the lower half thereof, and also serve to reinforce approximately the lower half of the car stopper body (10). The car stopper (A) according to the illustrated embodiment can be attached and fixed to the road surface of a parking lot by the anchor bolt receiving tubes (19L) (19R) and anchor bolts that penetrate the bottom plate, which will be described later.

[0043] Furthermore, the entire inside (back side) of the inclined front wall surface (12F), which serves as the wheel receiving surface of the car stopper body (10), is shaped as a light-reflecting surface (21) consisting of a diamond-cut surface or other uneven rough surfaces as shown in Figure 13. This allows the light received from the vehicle to be reflected retrogradely in the direction from which it entered, or, preferably, due to the light diffusion lens effect and light transmission effect of the resin, to be diffusely reflected in all directions, thereby obtaining a wide irradiation range and high illuminance that allows the presence and position of the car stopper (A) to be clearly seen even from a distance.

[0044] (22) denotes a plurality of bolt receiving holes (six in the illustrated example) distributed along the peripheral portion of the car stopper body (10). Although not shown in the figure, bolts for assembling the bottom plate (30) are inserted from above through these holes and are fastened to fixing nuts at their lower ends.

[0045] The bottom plate (30) covers the underside of the opening of the car stopper body (10) and has the same rectangular shape as the car stopper body (10) in plan and bottom view. However, due to the nature of the assembly relationship with the car stopper body (10), it is integrally formed into a special shape as shown in Figures 6 to 9 from polycarbonate resin, fiber-reinforced resin, ABS resin, polyacetal, or other hard synthetic resin.

[0046] That is, a waist wall (inner wall) (31) which is surrounded and covered by the front and rear wall surfaces (12F) (12R) and the left and right wall surfaces (13L) (13R) of the car stop body (10) is erected continuously and integrally for a certain height (h1) (e.g., 25 to 30 mm) from near the peripheral portion of the bottom plate (30), and along the peripheral portion outside the waist wall (31), bolt receiving holes (32) which align with and communicate with the bolt receiving holes (22) on the car stop body (10) side are distributed.

[0047] In this case, as is clear from Figures 6 and 7, a hexagonal nut receiving hole (33) is provided in a stepped communicating state on the underside of the bolt receiving hole (32) in the bottom plate (30), and an assembly bolt (not shown) for attaching the bottom plate (30) to the car stopper main body (10) is inserted from the bolt receiving hole (22) on the car stopper main body (10) side to the bolt receiving hole (32) on the bottom plate (30) side, and fastened to a nut (not shown) that is fixed and maintained in the nut receiving hole (33).

[0048] The waist wall (31) of a certain height (h1) is arranged upright along the peripheral edge of the bottom plate (30), and at appropriate intermediate positions between the front and rear wall portions and the left and right side wall portions, a plurality of drainage holes (34) (11 in the example shown) are cut out and distributed in a scattered manner as shown in Figure 6, so that rainwater and other moisture that has seeped in and accumulated inside the hollow interior of the car stopper body (10) can be discharged to the outside.

[0049] Similarly, the left and right wall portions of the waist wall (31) are formed with concave stepped surfaces (35L) (35R) that correspond to the anchor bolt receiving tubes (19L) (19R) of the car stopper body (10) as shown in Figures 6 and 9, thereby enabling the lower ends of the anchor bolt receiving tubes (19L) (19R) to be stably received without the risk of swinging. (36) denotes anchor bolt receiving holes formed in the centers of the lower end receiving concave stepped surfaces (35L) (35R), which of course mate with and communicate with the anchor bolt receiving tubes (19L) (19R) on the car stopper body (10) side to receive an anchor bolt not shown.

[0050] Furthermore, of the waist walls (31) arranged in a row along the peripheral portion of the bottom plate (30), the upper end of the waist wall (31) rising from the rear wall portion by a certain height (h1) has a plurality of rib support bosses (37) (five in the illustrated example) scattered as shown in Figures 6 to 9, which are continuously extended upward by a certain height (h2) (for example, about 25 mm or up to about half the height of the car stopper body).

[0051] The multiple rib support bosses (37) receive the lower ends of the vertical reinforcing ribs (16) that protrude continuously inward a certain amount (Z) from the top wall surface (11) and the front and rear wall surfaces (12F) (12R) of the car stopper body (10), particularly the lower ends of the vertical reinforcing ribs (16) that protrude along the rear wall surface (12R), as shown in Figures 11 and 13, and keep the wiring receiving tunnel (17) in a covered state from below, so that their positions and number are set to correspond to those of the vertical reinforcing ribs (16).

[0052] In addition, while the vertical reinforcing rib (16) in the illustrated embodiment is in the form of a plate, the rib support boss (37) is in the form of a cylinder, but the shape is not limited to a cylindrical shape and may be a columnar shape, a square tube shape, or any other shape.

[0053] The car stopper (A) according to the illustrated embodiment has the above-mentioned configuration, and the waist wall (31) of the bottom plate (30) is inserted from below into the hollow interior (S) of the car stopper main body (10), the bottom plate (30) is placed against the underside of the opening of the car stopper main body (10) in a covering state, and a plurality of bolts (not shown) are inserted from above into the bolt receiving holes (32) of the bottom plate (30) through the bolt receiving holes (22) of the car stopper main body (10). Fixing nuts (not shown) are then fastened to the lower end portions (tips) of the bolts, respectively. As a result, the waist wall (31) standing at a certain height (h1) as shown in Figures 11 to 13 can be used as a reinforcing inner wall of the car stopper main body (10), and the bottom plate (30) can be assembled and integrated into the car stopper main body (10) in a stable fitted state.

[0054] When the car stopper (A) as an assembled, integrated product is to be installed and used in an outdoor parking lot of a shopping center, for example, it can be attached and fixed to the road surface of the parking lot, which may be a concrete surface or an asphalt pavement surface, by means of anchor bolts (not shown) which are inserted into the pair of left and right anchor bolt receiving nozzles (19L) (19R) in the car stopper body (10) and the pair of left and right anchor bolt receiving holes (36) corresponding to the bottom plate (30).

[0055] The anchor bolts may be hole-in anchors or other post-installed anchor bolts, but instead of or in addition to using anchor bolts as a fixing means, it is also possible to apply an epoxy resin adhesive, silicone resin adhesive, or other adhesive for concrete or asphalt to the flat underside of the base plate (30) and then use the adhesive to affix and fix it to the road surface of the parking lot, which provides the convenience of easily installing and constructing the car stopper (A) on the road surface of an existing parking lot.

[0056] In any case, the car stopper body (10) of the above-mentioned car stopper (A) is molded as a whole as a single unit from colored transparent polycarbonate resin, and the entire inside (back side) of the inclined front wall surface (12F), which serves as the wheel receiving surface for the vehicle, is shaped as a light-reflecting surface (21) consisting of diamond-cut surfaces and other uneven and rough surfaces. Therefore, when light is projected from a parked vehicle at night, the light-reflecting surface (21) not only has a retroreflective effect, but also exhibits a light-diffusing lens (diffuse reflection) effect. Combined with the high light transmittance of the transparent polycarbonate resin, the bright light that shines widely in all directions from the car stopper (A) makes the location of the car stopper (A) easily visible even from a distance at night, not only to the driver of the parked vehicle, but also to the surrounding area of ​​the parked vehicle and pedestrians in the large parking lot, and there is no risk of accidents such as pedestrians tripping and falling.

[0057] Moreover, in the hollow interior (S) of the car stopper body (10) in the above-mentioned car stopper (A), a plurality of vertical reinforcing ribs (16) and horizontal reinforcing ribs (15) are arranged in a lattice pattern, and a pair of anchor bolt receiving tubes (19L) (19R) which serve as a reinforcing structure are also erected at the corners where the top wall surface (11) of the car stopper body (10) and the left and right side wall surfaces (13L) (13R) intersect, while the waist wall (31) which stands continuously and integrally from the bottom plate (30) can function as a reinforcing inner wall for the front and rear wall surfaces (12F) (12R) and the left and right side wall surfaces (13L) (13R) of the car stopper body (10) which surrounds it. Therefore, even if it is repeatedly subjected to impacts and loads from vehicles, etc., there is no risk of it being improperly deformed or cracked, and a car stopper (A) which is highly rigid can be obtained despite being a lightweight synthetic resin product.

[0058] In the car stopper (A) of the illustrated embodiment, a plurality of LEDs (light-emitting diodes) (40) (four in the illustrated example) that emit light toward the front wall surface (12F) on which the light-reflecting surface (21) is formed are installed at a mid-height position of the rear wall surface (12R) of the car stopper main body (10), preferably at a mid-height position corresponding to approximately half the height (H), on the inside (rear side) of the car stopper main body (10) in a generally horizontally aligned state as shown in Figures 11 and 13.

[0059] In addition, a battery storage recess (41) that is recessed to a certain depth (d) (e.g., 25 to 30 mm) is provided in the center of the flat top wall surface (11) of the car stopper body (10). Inside this recess (41) are stored a battery-integrated solar panel (42) that serves as the power source for the LED (40), a control circuit board (not shown), and a brightness detection sensor that turns on the LED (40) at night and turns it off during the day.

[0060] The battery (43) charged by the natural energy of the solar panel (42), the control circuit board and the brightness detection sensor are built into a separate small box (not shown) made of ABS resin or other flame-retardant resin as a set, and the small box is stored in the battery storage recess (41) of the car stopper body (10). (44) is a removable protective cover that covers the battery storage recess (41) in a watertight manner, and is also made of transparent polycarbonate resin.

[0061] However, instead of the battery-integrated solar panel (42), a solar cell (not shown) that serves as a power source for the LED (40) may be fitted into the recess (41) and used.

[0062] Electrical connection wiring (45) between the plurality of LEDs (40) and a battery (43) that serves as a power source for the LEDs (40) is passed through the inside of the tunnel (17) in a transverse manner, as shown in FIGS. 11 and 13.

[0063] In this case, the tunnel (17) is located at the same height (lower end) of the multiple (five rows in the illustrated example) vertical reinforcing ribs (16) that protrude inward by a certain amount (Z) from the rear wall surface (12R) of the car stop body (10), so the electrical connection wiring (45) inserted therein is installed in a nearly horizontal state. Moreover, the multiple LEDs (40) scattered along the connection wiring (45) are aligned horizontally between the adjacent vertical reinforcing ribs (16) as shown in FIG. 11, and irradiate the entire light reflecting surface (21).

[0064] According to the car stopper (A) of the illustrated embodiment, not only is the entire inside (back side) of the front wall surface (12F) of the car stopper main body (10) shaped as a light reflecting surface (21), but also, light is emitted from a plurality of LEDs (40) mounted side by side on the left and right sides at a mid-height position of the rear wall surface (12R) toward the light reflecting surface (21) of the front wall surface (12F). Moreover, since the car stopper main body (10) itself is integrally molded from a colored transparent polycarbonate resin, the light emitted from the LEDs (40) is reflected by the light reflecting surface (21) of the front wall surface (12F). The light is brightly illuminated in all directions not only from the front wall surface (12F) which forms the wheel receiving surface, but also from the top wall surface (11), rear wall surface (12R) and left and right side walls (13L) (13R), so that it can serve as a lighting fixture in a vast outdoor parking lot that replaces street lights at night, allowing pedestrians in the parking lot to easily see the location of the car stopper (A2) even from a distance. This provides an even safer car stopper (A2) not only for drivers of parked vehicles, but also for pedestrians in a vast parking lot where multiple car stops (A2) are installed in parallel.

[0065] Furthermore, by changing the color of the car stopper body (10) made of the polycarbonate resin, it is possible to divide the parking areas for each store in a vast outdoor parking lot so that they can be identified even at night, and it can also be used as a lighting lamp that distinguishes and indicates each floor of a multi-story parking lot at night, thereby providing convenience in installation and use.
