Description

Technical Field

[0001] The present invention relates to a decorative cover that is retrofitted to renew an existing concrete vehicle stopper block and add luminous performance at the same time.

Background Art

[0002] For example, in large outdoor parking lots such as shopping centers and other large-scale retail stores, as well as amusement facilities, factories, and new towns, a large number of concrete vehicle stopper blocks are installed in parallel. However, those vehicle stopper blocks have discolored and become dirty during years of use, or have chipped or cracked due to collisions with vehicles, etc., and are in an unsightly state, but are left as they are.

[0003] In this regard, instead of performing major construction to replace with new vehicle stoppers, a method of repairing existing vehicle stoppers is disclosed in Patent Document 1. Also, a vehicle stopper block composed of a cover part and a concrete part filled inside thereof is described in Patent Document 2.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, since the reinforcing cover (13) used in the repair method of Patent Document 1 is only manufactured in a shape slightly larger than the existing vehicle stopper (10), even if it is made of weather-resistant plastic or weather-resistant fiber-reinforced plastic, it is difficult to distinguish from the concrete surface of the parking lot. In particular, not only the driver of the vehicle parked at night or during rainfall, but also the pedestrians in the parking lot cannot clearly visually recognize the presence and position of the vehicle stopper.

[0006] Moreover, even if the repair method of the vehicle stopper is a method of covering the existing vehicle stopper (10) with the reinforcing cover (13), the mutual gap (filling state of the filler) between the two cannot be visually observed from the outside of the reinforcing cover (13). In order to prevent the occurrence of the mutual gap (insufficient filling), as shown in Figs. 2(a) and (b), a lump (appropriate amount) of uncured resin concrete (18) is placed on the upper surface of the vehicle stopper (10), and the reinforcing cover (13) is covered and pressed from above. Therefore, not only is the operation extremely troublesome, but there is also a risk that the resin concrete (18) will overflow from below during the pressing and stain the surroundings. Also, in the case of the method of providing an appropriate number of injection holes in the ceiling portion (21) of the reinforcing cover (13) and filling the resin concrete (20) therefrom as shown in Fig. 3, the injection holes must be covered after the filling, which is also complicated, and it is not possible to efficiently repair a large number of existing vehicle stoppers (10) in a short time.

[0007] Furthermore, due to the hardening of the resin concrete (18)(20) filled in the mutual gap between the reinforcing cover (13) and the existing vehicle stopper (10), the reinforcing cover (13) is fixed and integrated to the entire surface of the vehicle stopper (10). Therefore, if the reinforcing cover (13) becomes dirty or cracked during long-term use, replacing only the reinforcing cover (13) with a new one is a major project, and the repair of the existing vehicle stopper (10) cannot be repeated.

[0008] On the other hand, although the car stop block (10) described in Patent Document 2 has a cover portion (1) which is a resin casing, it is a new product which also has a concrete portion (2) filled with concrete inside, and therefore cannot be considered a decorative cover which can be retrofitted to cover an existing car stop block to renew the existing car stop block. [Means for solving the problem]

[0009] The present invention aims to improve on these problems, and in order to achieve this aim, claim 1 provides a decorative cover that can be attached to an existing car stop block, comprising a cover body integrally molded from colored transparent polycarbonate resin into a rectangular shape extending in the left and right lateral directions in a plan and bottom view that corresponds approximately to the existing concrete car stop block, and a hollow, approximately trapezoidal shape that opens downward on the side cross section;

[0010] A plurality of LEDs are arranged side by side on the inner surface of the cover body and emit light forward or diagonally downward;

[0011] A battery that serves as a power source for the LEDs and a solar panel for charging the battery are housed in a recessed groove recessed from the top wall surface of the cover body.

[0012] A detachable transparent cover for the groove is provided.

[0013] The cover body is placed from above over an existing concrete car stop block, and the ground flange that projects continuously and integrally from the lower edge of the opening is fixed to the concrete or asphalt road surface of the parking lot with an adhesive for concrete or asphalt.

[0014] In claim 2, a plurality of vertical reinforcing ribs and / or horizontal reinforcing ribs capable of functioning as spacers are continuously and integrally extended from the inner surface of the cover body, and the protruding tips of the reinforcing ribs are fixed to the existing concrete car stop block. corresponding It is characterized in that it is designed to abut or engage with the outer surface.

[0015] In claim 3, a plurality of LEDs are attached to the front wall portion for partitioning the concave groove in the cover body in a side-by-side state from the inside of the cover body so as to be able to irradiate the inclined front wall surface that becomes the wheel receiving surface, and

[0016] the above-mentioned plurality of LEDs and a battery-integrated solar panel that serves as its power source loop are electrically connected by wiring, which is characterized in that.

[0017] In claim 4, the entire inner surface of the inclined front wall surface that becomes the wheel receiving surface in the cover body is shaped as a diamond cut surface or other uneven rough surface that diffuses the light emitted from the LED, which is characterized in that.

Effect of the Invention

[0018] According to the above configuration of claim 1, there is an effect that the problems of the prior art described in the initial patent document 1 can be completely solved.

[0019] That is, in the decorative cover described in claim 1, a hollow cover body having a size and shape that substantially correspond (fit) to the existing concrete vehicle stopper block is placed over the vehicle stopper block from above, and a grounding flange protruding from the lower edge of the opening of the cover body is fixed to the road surface of the parking lot with an adhesive for concrete or asphalt. Therefore, it is possible to easily and efficiently perform retrofitting work on the existing vehicle stopper block.

[0020] Moreover, the cover body of the decorative cover is not fixedly integrated with the surface of the existing vehicle stopper block (B) via a filler, and the vehicle stopper block remains in its originally installed state. Therefore, if the decorative cover becomes unsightly, dirty, or damaged due to long-term use, only this can be replaced with a new one, and the grounding flange of the cover body can be adhered to the road surface of the parking lot in the same way, and this decoration can be repeated conveniently.

[0021] Furthermore, a plurality of LEDs (light-emitting diodes) are installed side by side inside the cover body. The battery serving as its power source and the solar panel for charging it are housed in a concave groove recessed from the top wall surface of the cover body. Since the LEDs emit light toward the inclined front wall surface that serves as the wheel receiving surface, combined with the fact that the cover body itself is made of a colored transparent polycarbonate resin, the lighting performance can be added to the existing parking block afterwards by the decorative cover that is put on the parking block. This is not only beneficial for the drivers of parked vehicles at night or during rainfall, but also for pedestrians in large outdoor parking lots, as they can clearly visually recognize the presence and position of the parking block from a distance, which helps to improve safety.

[0022] In that case, if the configuration of claim 2 is adopted, the state of the decorative cover being put on the existing parking block can be stably and firmly maintained. Combined with the fact that the cover body of the decorative cover is integrally formed from a hard polycarbonate resin with high impact resistance, there is no risk of being deformed or cracked illegally even when receiving a large load or impact from a vehicle or the like.

[0023] Also, if the configuration of claim 3 is adopted, since the plurality of LEDs attached side by side to the front wall portion for forming the concave groove on the top wall surface of the cover body are in a front diagonally downward posture and irradiate the inclined front wall surface that serves as the wheel receiving surface from the inside, combined with the light transmissibility of the polycarbonate resin in the cover body, extremely high illuminance can be obtained by the light emission of the LEDs.

[0024] Furthermore, if the configuration of claim 4 is adopted, since the entire inner side of the front wall surface that serves as the wheel receiving surface is shaped as a diamond-cut surface or other uneven rough surface, there is an effect of further improving the above-mentioned illuminance due to its light reflection effect and the light transmissibility of the polycarbonate resin.

Brief Description of the Drawings

Figure 5

[0026] A preferred embodiment of the present invention will be described in detail below with reference to the drawings. Figures 1 to 4 show the entirety of an aftermarket decorative cover (A) according to the embodiment, and (10) is a cover body that covers an existing concrete car stop block (including one with a reflector) (B), and is a rectangular shape extending elongatedly in the left and right lateral directions in a plan and bottom view that roughly corresponds (fits) with the car stop block (B), and is a hollow, roughly trapezoidal shape that opens downward in a side cross section, and is injection molded as a whole from transparent polycarbonate resin colored in orange, green, fluorescent, or other suitable color.

[0027] In other words, the cover body (10) of the decorative cover (A) is a one-piece molded product made of 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, for example 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, for example 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 almost the same steep inclination angle as the rear wall surface (12R), and a ground contact flange (14) protrudes outward in a continuous, integrated manner from the lower edge of the opening of the cover body (10).

[0028] Moreover, the wall thicknesses of the above-mentioned wall surfaces (11), (12F), (12R), (13L), and (13R) surrounding the hollow interior (S) of the cover body (10) are preferably all set to a relatively thick dimension of 3.5 to 4.5 mm. In combination with the material of the polycarbonate resin employed, it can exhibit excellent properties such as impact resistance, durability strength, high heat resistance temperature, and weather resistance.

[0029] Incidentally, in the cover body (10) of the illustrated embodiment, as an example of the size and shape that substantially correspond (match) to the existing vehicle stop block (B), in its plan and bottom views, the long side (length dimension) (Y) of the rectangle is 550 to 600 mm, the short side (width dimension) (X) is 160 to 180 mm, the width dimension (W) of the top wall surface (11) is 80 to 85 mm, and the height (height above the ground) (H) is 100 to 120 mm, respectively.

[0030] And in the hollow interior (S) that opens downward of the above-mentioned cover body (10), as is apparent from FIGS. 3 and 4, a plurality of long horizontal reinforcing ribs (15) extending parallel to the long side (Y) of the rectangle in its plan and bottom views project inward continuously and integrally by a certain amount (for example, 5 mm) from the top wall surface (11) and the left and right side wall surfaces (13L), (13R). On the other hand, a plurality of short vertical reinforcing ribs (16) extending parallel to the short side (X) of the rectangle also project inward continuously and integrally by substantially the same certain amount from the top wall surface (11) and the front and rear wall surfaces (12F), (12R). The vertical and horizontal reinforcing ribs (16), (15) are in a lattice arrangement state in the bottom view.

[0031] Such horizontal reinforcing ribs (15) and vertical reinforcing ribs (16) not only reinforce the above-mentioned cover body (10) literally, but also, when the cover body (10) is placed on the existing concrete vehicle stop block (B), the tip portions projecting inward abut or engage with the corresponding surfaces (outer surfaces) of the vehicle stop block (B), thereby also serving as a spacer function to keep the covering state stable and firm.

[0032] So long as the mutual distance between the vehicle stopper block (B) and the cover body (10) put thereon is kept substantially constant and the possibility of the cover body (10) moving illegally can be prevented, either one of the horizontal reinforcing ribs (15) and the vertical reinforcing ribs (16) may be omitted in its installation.

[0033] Also, if the grounding flange (14) is grounded to a road surface (GL) made of concrete, asphalt, etc. in a parking lot, the mutual distance between the wall surfaces (11), (12F), (12R), (13L), (13R) of the cover body (10) and the existing vehicle stopper block (B) will be kept constant. Therefore, the installation of the vertical and horizontal reinforcing ribs (16) and (15) may be omitted. However, in that case, the strength of the cover body (10) cannot be improved. Therefore, it is preferable to further increase the wall thickness of the wall surfaces (11), (12F), (12R), (13L), (13R) of the cover body (10).

[0034] Furthermore, the entire inner (back) surface of the inclined front wall surface (12F) serving as a wheel receiving surface of the cover body (10) is shaped as a diamond cut surface or other uneven rough surface (17) as shown in FIGS. 3 and 4. Thereby, the light received from the vehicle is retroreflected in the incident direction, or preferably diffused and reflected in all directions by the light diffusing lens action or light transmission action of the resin, so that the presence and position of the vehicle stopper block (B) can be clearly visually recognized even from a distance, and a wide irradiation range and high illuminance can be obtained.

[0035] Also, a concave groove (18) that sinks by a certain depth (for example, 10 to 20 mm) is formed in the flat top wall surface (11) of the cover body (10). Inside thereof, a battery (19) serving as a power source for an LED (light emitting diode) described later and a solar panel (20) for charging the battery (19) are preferably housed in a side-by-side state. (21) is a detachable transparent lid that covers the concave groove (18) in a watertight state, and this is also made of polycarbonate resin. A plurality of tapping screws and other fixing tools for attaching the transparent lid (21) are omitted in the drawing.

[0036] The front wall portion (22) that demarcates the concave groove (18) in a sunken state from the top wall surface (11) is preferably shaped as a flat inclined surface that intersects substantially at a right angle with the front wall surface (12F) which becomes the wheel receiving surface of the cover body (10) as shown in FIG. 4. A plurality of LEDs (light emitting diodes) (23) are installed in a side-by-side state on the inclined front wall portion (22), and the front wall surface (12F) with uneven rough surfaces (17) such as the diamond cut surface can be irradiated from the inside of the cover body (10) by the downwardly inclined front LEDs (23).

[0037] In that case, the plurality of LEDs (23) are implanted in a scattered distribution state on a flexible strip-shaped LED wiring board (24), and the LED wiring board (24) is preferably attached and fixed to the inclined front wall portion (22) of the concave groove (18) by a double-sided adhesive tape (25).

[0038] And, starting from the LED wiring board (24), the battery (19) charged by the solar panel (20), and a brightness detection sensor (not shown) that lights the LEDs (23) at night and turns them off during the day are electrically connected to a control circuit board (not shown). However, it is also acceptable to not use the LED wiring board (24) and make the electrical connection by wiring (power supply line).

[0039] In addition, if the front wall surface (12F) can be irradiated from the inside along the inclined front wall surface (12F) that becomes the wheel receiving surface of the cover body (10) by a plurality of LEDs (23), the installation locations of the LEDs (23) are not limited to only the front wall portion (22) of the concave groove (18), and other appropriate inner sides of the cover body (10) are also acceptable, and they can be installed in parallel in the forward directionality.

[0040] The attachable decorative cover (A) of the illustrated embodiment has the above configuration. When using it, the cover body (10) is placed over an existing concrete vehicle stopper block (including those with reflectors) (B) in an outdoor parking lot from above as shown in FIG. 5. Then, the grounding flange (14) that continuously projects integrally from the lower edge of the opening of the cover body (10) is fixed to the road surface (GL) composed of concrete, asphalt, etc. in the parking lot with an epoxy resin-based adhesive, a silicone resin-based adhesive, or other adhesives for concrete or asphalt (26).

[0041] In that case, when the cover body (10) of the decorative cover (A) is placed over the vehicle stopper block (B), the protruding tip portions of the plurality of vertical reinforcing ribs (16) and / or the plurality of horizontal reinforcing ribs (15) that project inward continuously from the cover body (10) abut or engage with the corresponding surface (outer surface) of the existing vehicle stopper block (B). Therefore, it conforms without the risk of floating in an improper direction or posture, and is maintained in a stable and firm covering state, enabling the renewal of the vehicle stopper block (B).

[0042] Moreover, in the state where the existing vehicle stopper block (B) is covered and decorated, the plurality of LEDs (23) built and installed in the cover body (10) emit light toward the front wall surface (12F) of the cover body (10) that serves as a wheel receiving surface, and irradiate the diamond-cut surface or other uneven and rough surfaces (17) of the front wall surface (12F) from the inside. Together with the fact that the cover body (10) is integrally formed from a transparent polycarbonate resin colored itself, not only for the driver of a vehicle parked at night or during rain, but also for pedestrians in a vast outdoor parking lot where numerous vehicle stopper blocks (B) are installed in parallel, the presence and position of the vehicle stopper block (B) can be easily visually recognized from a distance, and there is no danger of tripping and falling over the vehicle stopper block (B).

[0043] Also, by varying the coloring color of the cover body (10), it is possible to distinguish the parking areas for each store in a vast outdoor parking lot even at night, which is also helpful for improving convenience.

[0044] However, if the decorative cover (A) is damaged or becomes unsightly and dirty during long-term use, for example, only the decorative cover (A) can be replaced with a new one, and in the same way, with the cover body (10) still covering the existing concrete vehicle stopper block (B), the grounding flange (14) of the cover body can be fixed to the road surface (GL) of the parking lot with an adhesive (26). The existing vehicle stopper block (B) can remain in its fixed state, and by replacing only the decorative cover (A), its renewal can be easily repeated.
