Description

[Technical field]

[0001] The present invention relates to a car stopper that can be fixed by the weight of a vehicle. [Background technology]

[0002] When parking a car, to prevent the body of the car from going out of the parking space or colliding with a structure such as a fence, car stops that will come into contact with the tires of a moving car are often installed in the parking space.

[0003] Conventional car stops generally use roughly rectangular parallelepiped concrete blocks, and in most cases are connected to the ground by rebar or bolts that penetrate the concrete blocks. However, they often fall off the ground due to years of use or the momentum of the car when parking, and they become displaced significantly from their original installation position, making it impossible to achieve the purpose of stopping the car in the designated place.

[0004] In order to achieve the above-mentioned object, inventions that utilize the weight of the vehicle to prevent the car stopper from shifting or falling off have been proposed, including in References 1 and 2. In addition, several proposals have been made, such as Reference 3, that apply anti-slip treatment to the part that the tire rides over. [Prior art documents] [Patent documents]

[0006] However, previously proposed car stops have had all four corners fixed with bolts or the stopper part that the tire comes into contact with and the part that the tire rides over each been made out of separate parts, raising issues with their ease of installation and strength.

[0007] In view of the above circumstances, the present invention aims to provide a car stopper in which the stopper portion and the portion that the tire rides over are integrally molded by casting, and which has two fixing points, improving ease of installation. [Means for solving the problem]

[0008] The car stopper is made of aluminum and is integrally formed by casting. The car stopper is provided with a stopper and a tire mounting plate.

[0010] According to the invention described in claim 1, by using aluminum as the material, it is possible to provide a car stopper that is lightweight, strong, and rust-resistant. In addition, by making the bolt fixing point directly below the point where the tire touches the stopper, the moment of force around the bolt that occurs when the tire touches the stopper can be made the smallest possible moment, and as a result, the weight of the vehicle exceeds the moment, making it possible to prevent the car stopper from shifting or floating. Furthermore, by providing reinforcing ribs all over the lower surface of the tire mounting plate, it is possible to increase the bending rigidity of the tire mounting plate and prevent it from breaking due to the weight of the vehicle. In addition, by providing a non-slip surface on the upper surface of the tire mounting plate, it is possible to prevent the tire from spinning on the tire mounting plate when the vehicle starts. In addition, by providing an inclined portion at the front end of the tire mounting plate, the vibration of the vehicle when the tire runs up can be suppressed, making it possible to park smoothly.

[0011] According to the invention described in claim 2, in addition to the effects described above, the stability of the stopper is increased and the force with which the tire presses the stopper rearward can be reduced, thereby preventing damage caused by stress concentration at the boundary between the stopper and the tire mounting plate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] An embodiment of the car stopper of the present invention will be described in detail below. As shown in Fig. 1, the car stopper 1 of this embodiment is equipped with a stopper 2 having a substantially truncated quadrangular pyramid shape with long sides in the left-right direction, and a tire placement plate 3 extending forward of the stopper 2, and is integrally molded by casting using a sand mold. AC7A is used as the material for the car stopper 1, and the thickness of the side wall of the stopper 2 is 7 mm.

[0014] The stopper 2 has a hollow, roughly square pyramid-like external shape with long sides in the left-right direction, a left-right width of about 40 cm, a height of about 10 cm, and a front-to-back length of the top surface of about 4.5 cm. The front side of the stopper 2 has a sloping surface that flares out downward from the top surface, and is provided with the plate-like tire mounting plate 3 that extends forward from the sloping surface. The front-to-back length of the bottom surface including the tire mounting plate 3 is about 26 cm, and the boundary between the stopper 2 and the tire mounting plate 3 is smoothly connected by a curved surface.

[0015] The tire mounting plate 3 is provided with an anti-slip pad 4 having obliquely arranged convex portions on its upper surface, and an inclined portion 6 that slopes toward the ground at a front end portion of about 1.5 cm wide. The thickness of the tire mounting plate 3 gradually increases from 4 mm to 8 mm from the tip of the inclined portion 6 to the boundary with the stopper 2. In addition, as shown in Fig. 2, a vertical groove-shaped rib 5 is provided over the entire lower surface of the tire mounting plate 3 so as to be perpendicular to the longitudinal direction of the tire mounting plate 3, and the surface is slightly lower than the surrounding edge portion 9.

[0016] 2, bolt fixing portions 7, 7 are provided on the left and right sides near the boundary with the tire mounting plate 3 so as to be accommodated inside the hollow stopper 2.

[0017] Next, the use of the car stopper 1 of the present invention will be described with reference to Figs. When installing the car stopper 1, the bolt 8 inserted into the bolt fixing part 7 is long enough that the tip of the screw protrudes from the underside of the car stopper 1 by about 7 cm, and is inserted into a hole pre-drilled in the installation location of the parking lot. In addition, adhesive is applied to the entire underside where the ribs 5 are provided, and the car stopper 1 is fixed by inserting the bolt 8 and contacting it with the ground. When parking a car, just like in normal parking, the position of the vehicle body 100 is adjusted so that the tire 101 comes into contact with the car stopper 1, and the vehicle moves forward or backward slowly (see Figure 4(a)). The tire 101 then rides up onto the tire mounting plate 3 and comes into contact with the stopper 2 at contact point P, thereby stopping the vehicle body 100 (see Figures 3 and 4(b)).

[0018] In the vehicle stopper 1 configured as described above, the stopper 2 and tire mounting plate 3 are integrally molded by casting. Therefore, even if a moment of force is generated around the bolt 8 such that the stopper 2 would tip backward due to the impact of the tire 101 hitting it, the weight of the vehicle applied to the tire mounting plate 3 can prevent the stopper 2 from tipping over or shifting. The car stopper 1 of the present invention is fixed to the ground at the boundary between the stopper 2 and the tire mounting plate 3 (see Figs. 2 and 4), and the bolt fixing part 7 is located almost directly below the contact point P where the tire 101 contacts the stopper 2, so that the distance from the bolt 8, which serves as the fulcrum when the car stopper 1 falls over, can be made as small as possible, and the force moment around the bolt 8 generated as a result can also be made as small as possible. Then, the force moment around the bolt 8 generated at this time is balanced with or smaller than the vehicle weight on the tire mounting plate 3, so the car stopper 1 is prevented from falling over by the vehicle weight, making it more difficult to fall over and less likely to shift than conventional car stops. As a result, the car stopper 1 of the present invention can be fixed by pressing only at two points, the left and right ends of the stopper 2 and the tire mounting plate 3, and therefore the car stopper 1 can be made to be easy to install and cost-effective.

[0019] In addition, the tire mounting plate 3 has an anti-slip surface 4 and an inclined portion 6 on its upper surface, which prevents the tire 101 from spinning on the tire mounting plate 3 and makes it easier to ride up, thereby helping the vehicle to move more smoothly. At this time, by configuring the thickness of the tire mounting plate 3 to gradually increase from the tip of the inclined portion 6 to the boundary with the stopper 2 at a thickness of 4 mm to 8 mm as in this embodiment, it becomes difficult to notice that the tire 101 has run up onto the tire mounting plate 3, and it is possible to provide a safer and more natural car parking comfort than a conventional car stopper having a similar configuration. In addition, by using aluminum as the material, it is possible to exhibit the toughness, rust prevention, and corrosion resistance unique to aluminum even with a thickness of 4 mm to 8 mm. In addition, a load-bearing test was also conducted, and no change in shape was observed in the stopper 2 up to a direct downward pressure of 6 tons. This makes it clear that if the tire 101 runs up onto the stopper 2 during parking, there is no risk of deformation for a standard car that is popular in ordinary households. In addition, considering that only the front or rear wheels of a vehicle may run over the stopper 2, the possibility of deformation of this wheel stopper 1, which can withstand a direct downward pressure of 6 tons even for a mid-sized vehicle, is extremely low, so it is highly anticipated that it will be used not only for home use but also for corporate use, such as by installing it in the parking lots of tourist bus companies and transportation companies.

[0020] In addition, ribs 5 that are perpendicular to the longitudinal direction of the tire mounting plate 3, that is, that extend in the front-rear direction, are provided over the entire underside of the tire mounting plate 3, thereby increasing the bending rigidity in the front-rear direction of the tire mounting plate 3. Increasing the bending rigidity makes it possible to prevent breakage that would otherwise occur due to bending of the tire mounting plate 3 caused by the weight of the vehicle, making it possible to provide a stronger car stopper 1 than before.

[0021] In addition, by making the front side of the stopper 2 a sloping surface that diverges downward from the top surface, when the tire 101 hits the stopper 2, the impact from the tire 101 can be deflected by the amount of the sloping front side, compared to when the front side is a straight wall. Therefore, distortion is less likely to occur at the boundary between the stopper 2 and the tire mounting plate 3, and shearing at that location can be prevented. Furthermore, by making the boundary between the stopper 2 and the tire mounting plate 3, which is the most heavily loaded when the tire 101 hits the stopper 2, a curved surface is made on the upper surface of the car stopper 1, so that the points at which stress is concentrated at the boundary when the tire 101 presses the stopper 2 are somewhat dispersed, and the probability of destruction due to stress concentration can be reduced. In addition, by connecting the boundary between the stopper 2 and the tire mounting plate 3 with a curved surface, paint does not accumulate during surface painting, allowing the entire car stopper 1 to be painted evenly, and when a sand mold is used for molding, the sand mold is less likely to collapse, improving the design of the molded car stopper 1.

[0022] In addition, since the lower surface of the tire mounting plate 3 is positioned slightly lower than the edge portion 9, the entire lower surface is recessed like a dish, making it easier to apply adhesive to the entire lower surface. In addition, since the bolt fixing portion 7 is positioned so as to be concealed in the hollow portion of the stopper 2, the bolt 8 is not exposed on the surface of the car stopper 1, which makes it possible to prevent deterioration of the car stopper 1 body due to intrusion of rainwater, etc. through the bolt fixing portion 7, and corrosion of the bolt 8, and also makes it possible to provide a car stopper 1 with good design.

[0023] The car stopper 1 of the present invention is not limited to the above embodiment, and may be modified as appropriate within the scope of the claims. For example, AC7A is used as the material in the embodiment, but other aluminum alloys for casting may be used. In addition, the shape of the slip prevention is a convex oblique line in this embodiment, but any shape may be used as long as it has a slip prevention function that prevents the tire from spinning, and in some cases, the product logo may be raised to provide a slip prevention function. In addition, the rib 5 does not have to be oriented perpendicular to the longitudinal direction of the tire mounting plate 3, and may be arranged obliquely as long as it increases the strength of the tire mounting plate 3.
