Description

Car stopper

[0001] The present invention relates to a car stopper, and more particularly, to a car stopper configured to increase durability by reducing external force applied to the car stopper when a vehicle is parked, thereby preventing damage to the car stopper, while also promoting convenience in construction and extending the maintenance cycle.

[0002] A car stopper or barrier is installed horizontally inside the boundary line that indicates a designated parking space. When a parked vehicle backs up, it prevents the vehicle from going beyond the designated parking space and hitting a wall, or colliding with a vehicle in an opposing parking space. This ensures the safety of the vehicle by stopping the rear wheels and also serves to guide the driver to the location where the vehicle should stop.

[0003] In the case of a generally known car stopper, as disclosed in Korean Utility Model Registration No. 0396005 (published on September 14, 2005), it is common to insert a body part (10) having a mounting hole (11) formed in an anchor bolt (12) connected to the ground and connect it with a fastening nut (13).

[0004] However, whenever a vehicle is parked, the car stopper receives a large external force in one direction from the vehicle's wheels, but the anchor bolt that secures the car stopper is made of a hard metal material and does not help in reducing the external force received by the car stopper.

[0005] Accordingly, the force that the car stopper receives from the vehicle's wheels and the reaction force generated by the fixed anchor bolt that comes into contact with the car stopper that is pushed by the force act together on the car stopper, resulting in a decrease in the durability of the car stopper and frequent occurrence of damage such as wear and tear.

[0006] Among the technologies for solving this problem, as disclosed in Korean Patent Publication No. 2008-0039201 (published on May 7, 2008), a technology for a car stopper for vehicle parking is disclosed, which has a car stopper structure sized to have a fixed bracket inserted into the bottom of a parking block, and a vehicle wheel contact surface of the parking block has a curved slope and a fixed bolt joint is formed on the curved slope so that when the vehicle wheel moves backward along the curved slope, the vertical load of the vehicle is transferred to the car stopper and the parking block is not pushed out, and a fixed bracket for fixing the parking block to the ground is fixed to the concrete surface of the ground with an anchor bolt to support the parking block, but the fixed bracket in contact with the ground surface is provided as a flat plate on both sides and has a protruding catch in the center, and a plurality of spare holes are provided in the fixed bracket so that the fixed bracket can be coupled and fastened by bolts, so that when the fastening part on one side is damaged, it can be moved to another hole and fastened to the fixed bracket.

[0007] However, the above technology is such that the load of the wheel is applied to one side of the car stopper rather than one end by fitting the curved slope to the shape of the wheel, so that the total amount of load received by the car stopper is the same regardless of the shape, and the bolt supporting the car stopper is made of metal and cannot absorb the impact applied to the car stopper, so there is still a great problem that the car stopper may be damaged.

[0008] Additionally, even if the car stopper is hard enough to support the impact applied from the vehicle, it is known that when the parking brake is applied while the vehicle is resting on the car stopper, a large force is applied to the parking pawl, which is a transmission component of the vehicle, causing the parking pawl of the vehicle to break.

[0010] (Patent Document 0002) KR 10-2008-0039201 A (May 7, 2008)

[0011] The present invention is intended to solve the problems of the above-mentioned prior art, and the purpose of the present invention is to provide a car stopper in which a car stopper is formed of a front support part and a rear support part having different hardnesses, and the front support part that comes into contact with the wheel of the vehicle is formed of a material having lower hardness and is deformable, thereby self-attenuating the impact received by the car stopper when it hits the wheel of the vehicle and preventing a failure that may occur in the parking pawl of the vehicle.

[0012] In addition, the present invention aims to provide a car stopper that facilitates the connection of the front support portion and the rear support portion to facilitate construction, prevents loosening of anchor bolts, and extends the maintenance cycle by preventing direct contact of moisture such as rainwater with the fastening portion of the anchor bolt and nut.

[0013] In addition, the present invention aims to prevent damage to a parking pawl, which is a vehicle transmission component, by attaching a warning device to a car stopper.

[0014] In addition, other purposes that are not described separately but can be inferred by considering the specific contents and claims for carrying out the invention described below are also included in the overall subject matter of the present invention.

[0015] The present invention relates to a car stopper comprising a front support portion and a rear support portion having different hardnesses, wherein the front support portion is formed of a material having a lower hardness than the rear support portion so as to be deformed when in contact with a tire of a vehicle, and the rear support portion is formed of a material having a higher hardness to the extent that it can prevent deformation of the front support portion and movement of the vehicle, wherein the rear support portion comprises a fixed support plate, a protrusion formed forwardly on the fixed support plate so as to place an anchor bolt thereon and be capable of being engaged with a concave portion of the front support portion, and an anchor bolt embedded in the protrusion and buried in the ground, and wherein the front support portion comprises an inclined portion in contact with the tire of the vehicle, and a main body portion covering an upper surface of the rear support portion, wherein a concave portion for receiving the protrusion of the rear support portion is formed.

[0016] In one embodiment, the car stopper of the present invention may be formed such that the cross-section of the protrusion of the rear support portion has a trapezoidal shape and the width of the lower portion is narrower than the width of the upper portion.

[0017] In one embodiment, the car stopper of the present invention may be formed such that the concave portion of the front support portion is formed in a trapezoidal shape corresponding to the shape of the protrusion portion of the rear support portion, and a space of a predetermined width exists between the concave portion and the protrusion portion.

[0018] In one embodiment, the car stopper of the present invention may have a protrusion formed on the lower portion of the concave portion of the front support portion that protrudes inwardly from the concave portion.

[0019] In one embodiment, the car stopper of the present invention may be formed such that the depth of the concave portion of the front support portion is deeper than the length of the protruding portion of the rear support portion.

[0020] In one embodiment, the car stopper of the present invention may have a stamped portion formed on the upper part of the female thread of a nut fastened to an anchor bolt.

[0021] In one embodiment, the car stopper of the present invention may be equipped with a proximity sensor and a contact sensor.

[0022] The present invention has the effect of reducing the impact received by a car stopper when it hits a wheel of a vehicle by forming the front support portion and the rear support portion of a car stopper with different hardnesses and forming the front support portion in contact with the wheel of a vehicle with a material having lower hardness than the rear support portion, thereby enabling deformation, and at the same time preventing a failure that may occur in a parking pawl of the vehicle.

[0023] In addition, the present invention has the effect of not only facilitating construction by allowing the protrusion formed on the lower portion of the concave portion of the front support portion to be simply joined to the rear support portion, but also preventing direct contact of moisture with the fastening portion of the anchor bolt and nut, and preventing loosening of the anchor bolt, thereby extending the maintenance cycle.

[0024] In addition, the present invention has the effect of preventing damage to the parking pawl, which is a transmission component of the vehicle, by warning the driver not to park the vehicle with the wheels excessively off the ground through a proximity sensor and a contact sensor attached to the car stopper.

[0035]

[0036] Hereinafter, preferred embodiments for achieving the purpose of the present invention will be described with reference to the drawings attached to the present invention.

[0037] FIG. 2 is a perspective view of a car stopper according to an embodiment of the present invention, FIG. 3 is a plan view of the car stopper of FIG. 2, FIG. 4 is a cross-sectional view taken along the cutting line AA of FIG. 2, FIG. 5 is a cross-sectional view taken along the cutting line BB of FIG. 2, and FIG. 6 is a perspective view for explaining a stamped portion formed on the upper part of the female thread of a nut fastened to an anchor bolt of the present invention.

[0038]

[0039] The car stopper (1) of the present invention is formed by combining a front support part (20) and a rear support part (30) as shown in FIG. 2.

[0040] The front support part (20) is configured to include a sloped portion (21) that comes into contact with the tire of the vehicle, as shown in FIGS. 2 to 5, and a main body part (22) that extends from the sloped portion (21) and covers the upper surface of the rear support part (30), and is formed of a material having a lower hardness than the rear support part (30) so that it can be deformed when in contact with the tire of the vehicle, and a plurality of cavities (25) are formed.

[0041] In addition, the front support part (20) is formed with a concave portion (23) that can accommodate the protrusion (31) of the rear support part (30) in a lower part of the main body part (22). The concave portion (23) is formed in a trapezoidal shape corresponding to the shape of the protrusion (31) of the rear support part (30), but a space of a predetermined width exists between the concave portion (23) and the protrusion (31), and the depth thereof is formed in a square cross-sectional shape that is deeper than the length of the protrusion (31) of the rear support part (30).

[0042] As an example of a modified embodiment, the shape of the concave portion (23) may be changed to a shape that can accommodate a protrusion (31) formed on the rear support portion (30) and provide a space in which the inclined portion (21) of the front support portion (20) can be deformed when pressed by a wheel of a vehicle.

[0043] As described above, a cavity (25) is formed in the front support (20), and a space is formed between the concave portion (23) of the front support and the protrusion (31) of the rear support, so that when the wheel of the vehicle comes into contact with the front support (20) and pressure is applied, the portion of the front support that receives the pressure is deformed into the cavity (25) and the space, thereby reducing the pressure, thereby alleviating the impact applied to the car stopper (1) and the anchor bolt (33), and at the same time alleviating the impact transmitted to the vehicle.

[0044] As a result, the shock that causes the nut (34) to loosen from the anchor bolt (33) is alleviated, preventing the car stopper from shaking and reducing the need for maintenance.

[0045] Meanwhile, it goes without saying that the cavity (25) formed in the front support (20) and the space formed between the concave portion (23) of the front support and the protrusion (31) of the rear support can be appropriately adjusted by simulation according to the front support material and the design stress to be buffered.

[0046] In addition, a protrusion (24) protruding inwardly from the concave portion (23) of the front support portion (20) is formed at the bottom of the concave portion (23), so that when the front support portion (20) and the rear support portion (30) are combined, the protrusion (24) can be caught at the bottom of the protrusion (31) of the rear support portion (30).

[0047] Furthermore, a proximity sensor (50) and a contact sensor (51) can be installed in the front support member (20).

[0048] The proximity sensor (50) is configured to detect when a vehicle approaches the car stopper (1) within a certain distance and transmit a warning signal, and the contact sensor (51) is configured to detect when a wheel of the vehicle contacts the car stopper (1) and transmit another warning signal so that the driver can be notified of this.

[0049] Since the above proximity sensor (50) and contact sensor (51) can be installed according to known sensors and installation methods, a detailed description thereof is omitted.

[0050]

[0051] Meanwhile, the rear support (30) includes a fixed support plate disposed on the lower part of the main body (22) of the front support (20), a protrusion (31) formed to protrude forward from the fixed support plate and capable of being accommodated in a concave portion (23) of the front support (20), and an anchor bolt (33) embedded in the protrusion (31) and buried in the ground, and is formed of a material having a hardness sufficient to support deformation of the front support (20) and ultimately support a vehicle.

[0052] Any material that has a hardness sufficient to support the vehicle, such as a known plastic material or steel material, can be used as the material for the rear support member (30) as described above.

[0053] As shown in FIG. 3, the protrusion (31) formed protruding from the rear support member (30) has a trapezoidal cross-section when viewed from above, and as shown in FIG. 4, the width of the lower portion is narrower than the width of the upper portion, so that the protrusion (24) formed at the lower portion of the concave portion (23) of the front support member (20) is formed to be inclined so that it cannot easily fall upwards. A through hole (32) having a size into which an anchor bolt (33) can be inserted is formed in the protrusion (31) formed protruding from the rear support member (30).

[0054] The above protrusions (31) can be increased or decreased depending on the length of the car stopper (1), but it is preferable that they be configured with at least two or more so that the car stopper (1) does not rotate due to the force received from the wheels of the vehicle.

[0055]

[0056] Referring to FIGS. 4 and 5, the anchor bolt (33) is first installed on the ground where the car stopper (1) is to be installed, and then its upper part is inserted through a through hole (32) formed in the protrusion (31) of the rear support part (30) to fix the rear support part (30) by a fastening nut (34). After the rear support part (30) is fixed by the anchor bolt (33) in this way, when the main body (22) of the front support part (20) is placed on the upper part of the rear support part (30) and pressed downward, the protrusion (31) of the rear support part (30) is inclined downward, so that when the front support part (20) is coupled to the rear support part (30), the lower protrusion (24) formed in the concave part (23) of the front support part (20) catches on the lower part of the protrusion (31) formed protruding from the rear support part (30), thereby fixing the car stopper (1).

[0057] When the front support (20) and the rear support (30) are combined as above, the anchor bolt (33) and the nut (34) that fastens the anchor bolt (33) are not exposed to the outside, which has the effect of reducing corrosion caused by direct contact with moisture such as rainwater.

[0058] Meanwhile, referring to Fig. 6, a stamped portion (35) may be formed on the upper portion of the female screw (36) of the nut (34) fastened to the anchor bolt (33). As described above, when a portion of the screw thread collapses due to the stamped portion (35) formed on the upper portion of the female screw (36) and the pitch of the screw is reduced, when the nut (34) is fastened to the anchor bolt (33) later, the collapsed screw thread causes the contact angle with the screw thread of the anchor bolt (33) to increase, making it difficult for the nut (34) to be loosened from the anchor bolt (33), and ultimately, the rear support member (30) can be stably fixed to the ground.

[0059]

[0060] The car stopper (1) configured as above can detect when the wheels of a vehicle to be parked approach within a predetermined distance through a proximity sensor (50) and issue a warning signal so that the driver can roughly predict the point at which to stop, and then when the wheels of the vehicle come into contact with the car stopper (1), a contact sensor (51) can detect this and issue another warning signal so that the driver can stop immediately.

[0061] This prevents the vehicle from excessively pushing the car stopper (1) backwards, and at the same time prevents damage to the transmission parts of the vehicle, i.e. the parking pawl, which may occur when the vehicle is parked with the car excessively elevated above the car stopper (1) and then restarted.

[0062]

[0063] Meanwhile, when the vehicle is parked and the vehicle's wheels come into contact with the front support (20) of the car stopper (1) and the vehicle moves further, the front support (20) of the car stopper (1) is deformed due to the weight of the vehicle.

[0064] The front support (20) used in the present invention is formed of a rubber product such as NBR (acrylonitrile butadiene rubber), which has excellent cushioning and restoring force. Normally, rubber is incompressible and deforms without being compressed. When the front support (20) is pressed while the vehicle is parked as described above, the front support (20) that is pressed into the space between the concave portion (23) formed in the front support (20) and the protrusion (31) formed in the rear support (30) and into the cavity (25) formed in the front support (20) deforms to support the vehicle. As the vehicle moves further and the force applied from the vehicle increases, the front end of the concave portion (23) of the front support (20) comes into contact with the protrusion (31) of the rear support (30), and then the side surface of the concave portion (23) of the front support (20) also comes into contact with the side surface of the protrusion (31) of the rear support (30). At this time, since the side surface of the protrusion (31) of the rear support (30) is formed in a trapezoidal shape, friction with the side surface of the concave portion (23) of the front support (20) that is being deformed becomes severe, making it difficult for the front support (20) to deform, thereby allowing the force supporting the vehicle to increase. If this condition continues, the front support (20) and the rear support (30) are completely pressed together, and there is almost no space between the concave portion (23) of the front support (20) and the protrusion (31) of the rear support (30), so that the front support (20) and the rear support (30) behave as if they are a car stopper (1) made of one body, and support the vehicle, thereby functioning to resist the movement in the direction of travel of the vehicle.

[0065]

[0066] According to the present embodiment formed as described above, the car stopper can be deformed by using a material having a hardness lower than that of the rear support portion of the front support portion, and the proximity sensor (50) and contact sensor (51) attached to the car stopper enable the vehicle to be parked without the wheels of the vehicle excessively coming off the ground, thereby preventing a failure that may occur in the parking pawl of the vehicle, and also enabling the car stopper to self-attenuate the impact received.

[0067] In addition, the present invention has the effect of not only making construction easy by allowing the protrusion formed on the lower part of the concave portion of the front support portion to be combined with the rear support portion, but also preventing moisture from directly entering the fastening portion of the anchor bolt and nut, and preventing the anchor bolt from loosening, thereby extending the maintenance cycle.

[0068]

[0069] Although the present invention has been described with reference to the embodiments shown in the drawings, these are merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom, and therefore the true technical scope of the present invention should be determined by the technical idea of ​​the appended claims.
