BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wheel stopper for receiving a wheel of an automobile in a parking lot, a garage, or the like, and stabilizing its stop position.

[0002]

2. Description of the Related Art Generally, in a parking lot, a garage or the like, in order to stably stop an automobile at a predetermined position, a wheel stopper is installed which mainly receives a wheel of an automobile moving backward and prevents further movement. ing.

[0003] As such a wheel stopper, a metal, concrete or wooden wheel which is usually used has a large weight and is difficult to handle during installation work, etc., and is damaged or cracked by impact (concrete), Or crack damage or corrosion (wooden) is likely to occur and there is a problem with durability,
In particular, it cannot be said that it is suitable as a wheel stopper for general households.

In recent years, it has been considered that the wheel stopper is made of a synthetic resin material or a rubber material to reduce the weight and the durability. For example, Japanese Utility Model Application Laid-Open No. 62-8867 has been proposed as a wheel stopper formed of a synthetic resin material or the like.

In the proposed wheel stopper, the side surface of the convex portion which is the main body of the wheel stopper has an I-shaped shape, and the upward and downward lateral protrusions of this I-shaped side surface are short at the upper end side and short at the lower end side. The wheel tire is made long and first comes into contact with the upper end side protruding end and then comes into contact with the lower end side protruding end.

[0006]

However, in the case where the wheel tire is abutted against the upper end side protruding end of the convex portion which is the wheel stopper main body like the above-mentioned proposed wheel stopper, the upper end portion is first Since it is pushed backward by the wheels, a force that tilts the convex portion backward acts, and not only when it is simply placed on the ground surface or floor surface, but also when it is stopped by adhesive means, It may peel off or move backward. Further, when the fixing portion is fixed by the anchor bolt, a strong force may act on the fixing portion to cause damage.

Therefore, in the proposal, the plate-like portion on which the wheel rides is connected to the front lower end of the convex portion which is the wheel stopper main body, but in such a shape, integral molding with a synthetic resin material is performed. This is not preferable because it is not easy, the manufacturing cost is high, the handling such as grounding work is not easy, and there is a risk of breaking at the connecting portion between the plate-shaped portion and the protrusion.

The present invention has been made in view of the above, and is made of synthetic resin, can be easily manufactured by molding, is lightweight and easy to handle, and can be easily and suitably used for general household use, and the wheel receiving surface can be used. The above-mentioned shape feature provides a wheel stopper that is free from inclination, peeling or movement due to contact with a wheel tire.

[0009]

DISCLOSURE OF THE INVENTION The present invention for solving the above-mentioned problems is a convex block-shaped wheel stopper which is integrally molded of a synthetic resin material and has an inclined wheel receiving surface for receiving the wheel. The receiving surface has a rounded curved contact surface portion which is continuous through the recessed portion of the curved surface of an inverted round having no horizontal and vertical portions, and the lower contact surface portion is lower than the upper portion. When it extends long forward and the wheel tire comes into contact with the lower contact surface portion, the upper contact surface portion is located slightly outside the outer circumference of the wheel tire, and the wheel tires are in sequence with respect to the lower and upper contact surface portions. It is characterized in that they are formed so as to come into contact with each other with different phases.

[0010]

According to the wheel stopper of the present invention having the above-mentioned structure, when the wheel of the automobile comes into contact with the wheel receiving surface, the wheel tire has a lower portion of the upper and lower abutting surface portions of the wheel receiving surface, which are projected forward. First, it comes into contact with the rounded curved contact surface portion of the above to form a cushion, and then, after some time, contacts the upper rounded curved contact surface portion to stop the rolling of the wheel. When the speed of entry of the vehicle is high and the hit is strong, the outer peripheral surface of the tire comes into close contact with the recessed portion to stop rolling and prevent the vehicle from overcoming.

As described above, the contact of the wheel tires is carried out in two stages, whereby the impact at the time of contact is effectively dispersed, and the contact surface portion may have a rounded curved surface shape. The shock is alleviated. In addition, since there is a recessed space due to the curved surface of the reverse radius between the upper and lower contact surface portions, the force at the time of contact is also absorbed and dispersed by this recessed space.

In particular, in the case of the present invention, since the wheel tire comes into contact with the lower abutment surface portion that extends forwardly from the upper side and rides up slightly, the wheel stopper is pushed by the weight of the vehicle on the front side. After that, since the wheel tire comes into contact with the upper contact surface portion after that, a strong force does not act so much on the bonding portion to the ground surface or the floor surface or the fixing portion with the bolt, and peeling and movement can be prevented.

[0013]

Embodiments of the present invention will be described with reference to the drawings.

1 to 3 show an example of a wheel stopper according to the present invention. In the figure, (1) is a convex block-shaped wheel stopper having a length at least the width of the wheel integrally molded with a synthetic resin having moderate elasticity and toughness, such as a polyolefin resin, and its front surface. The side is formed as an inclined wheel receiving surface (2) substantially corresponding to the outer periphery of the lower portion of the wheel tire (T).

As shown in the drawing, the wheel receiving surface (2) has a rounded curved surface which is continuous through a recessed portion (3) which does not have a horizontal portion and a hanging portion due to a curved surface of an inverted rounded portion on its lower portion. Of the upper and lower contact surface portions (2a) and (2b), the lower contact surface portion (2) has the contact surface portions (2a) and (2b).
The b) is formed in a curved surface that is longer than the upper portion, and the upper contact surface portion (2a) is formed in a curved surface that has almost no forward protrusion. In particular, the contact surface portions (2
When the wheel tire (T) abuts the lower abutment surface portion (2a), the overhanging portions (a) and (2b) are extended.
b) is set so as to be located slightly outward of the outer circumference of the wheel tire (T), and the wheel tire (T) is sequentially phased differently with respect to the lower and upper contact surface portions (2b) (2a). It is formed so as to abut in stages.

It is also possible to form the upper contact surface portion (2a) in the shape of a rounded curved surface which projects forward, but in this case as well, the lower contact surface portion (2b) is further projected forward. Then, the wheel tires (T) are formed so as to sequentially contact the lower contact surface portion (2b) first.

If the inclination of the wheel receiving surface (2) from the lower contact surface portion (2b) to the upper contact surface portion (2a) becomes too gentle, the wheel tire (T) will contact the inclined surface. Since there is a possibility that the function of stopping the ascending wheels may not be achieved, it is preferable that the inclination angle is an acute angle, and this is easier to mold.

The wheel stopper (1) shown in the figure is also formed as a wheel receiving surface (2) of which the rear surface side is symmetrically the same as the front surface side, and has a front-rear symmetrical shape as a whole. Although it is not always necessary to make it symmetrical in the front-rear direction, if it is made symmetrical with the wheel receiving surfaces (2) and (2) in the front-rear direction, the supporting force at the time of wheel contact increases and is reinforced. When the receiving surface (2) is damaged or worn, it can be used by reversing the front and back, and the appearance is good.

The top portion (1a) of the wheel stopper (1) has an abutting surface portion (2a) on the upper and lower sides of the front and rear wheel receiving surfaces (2) and (2).
Although it may be formed on the same curved surface as (2a), in the case of the figure, the top portion (1a) is formed on a horizontal surface to form the name plate (4) or the like as a display portion to which the name plate (4) can be attached. . It is also possible to directly display the name and the like by painting. Of course, the display part such as the name can be provided in another part, for example, in the recessed part (3) of the wheel receiving surface (2), but the plate may be peeled off or the display cannot be seen due to the contact of the wheel. Therefore, it is desirable to provide the top portion (1a) as described above.

Bolt insertion holes (5) are provided at the left and right ends of the front and rear wheel receiving surfaces (2) and (2) of the wheel stopper (1) so that they can be fixed to the ground or floor with anchor bolts. Also, the nut seating recess (6) is provided to a depth such that the nut does not protrude from the surface. Of course, this wheel stopper (1) can be used by fixing it with an adhesive or simply by placing it on the ground or floor, depending on the needs such as where the bolt cannot be embedded. is there. In this case, it is preferable to provide an anti-slip means on the lower surface (7) serving as the ground contact surface as described below.

Lower surface (7) serving as a ground contact surface of the wheel stopper (1)
Can have a flat surface over the entire surface, but in the case of the figure, a recess (8) is provided at the center in the front-rear width direction in consideration of installation stability on the ground or floor and prevention of sliding. There is. Further, on the lower surface (7), as a non-slip means, an uneven strip (9) having a saw-like cross section in the longitudinal direction (left-right direction) is formed. The non-slip means may be provided with concavo-convex stripes or small convex portions in the front-rear width direction in parallel or in a scattered manner. Further, when the concave portion (8) and the uneven strip (9) for preventing slippage are formed as described above, the drying is accelerated when rainwater or the like enters under the wheel stopper (1).

The wheel stopper (1) is set to a height such that the wheels of the automobile do not get over and the underside of the vehicle body does not rub. For example, the height is 150 mm or less, preferably 135 to 145 m
m. The lateral length may be at least the width of the wheel, for example, 400 to 600 mm,
The width in the front-rear direction is, for example, 240 to 300 mm. Of course, the dimensions other than the above can be used.

As the synthetic resin for the constituent material of the wheel stopper (1), there may be used a polyolefin resin such as a polyethylene resin or a polypropylene resin or a copolymer resin mainly containing olefin, or other synthetic resin which is not easily broken. The above-mentioned polyolefin-based resin can be preferably used because it is easy to mold and hard to crack, but the polyolefin-based resin has a slightly large molding shrinkage, and may warp after molding, and deformation is likely to occur. A resin in which a rigid polystyrene resin is mixed with a resin and a styrene-ethylene copolymer resin can be particularly preferably used. In this case, the amount of polystyrene resin is preferably 20 to 75% by weight of the total amount. If it is more than this range, the molded product will be easily cracked, and if it is less than this range, the deformation after release will be large.

Further, as the synthetic resin material, a used synthetic resin product such as a molded product of polyethylene resin may be crushed and mixed into a raw material resin for reuse. The material resin can be colored appropriately. As a plastic material, a polyolefin-based resin is preferable because it is easy to mold and has few cracks, but there is a drawback that the deformation becomes large as the shape becomes complicated. Therefore, it is preferable to blend a resin having high rigidity such as polystyrene resin.

The wheel stopper (1) is molded by, for example, injecting and filling a raw material resin with an extrusion nozzle inserted in a molding die to heat-mold the molded product, and then shrinking the molded product by cooling after molding. Die longitudinally. Specifically, heat molding is performed for about 4 minutes, and the molding die is placed in a water tank after molding.
Immerse for a while to cool, and then remove the molded product from the mold. In particular, in the case where the lower surface (7) has a recess (8) as shown in the figure, the rod-shaped mold corresponding to this recess (8) is first removed to facilitate the die-cutting of the molded product. It can also be manufactured by injection molding.

The synthetic resin wheel stoppers (1) can be made much lighter than those made of cocrete or metal. For example, 25 kg of concrete is 8 kg.
The weight can be reduced to a certain degree. Therefore, handling such as transportation and installation work is easy and the name can be displayed.
Also, since it can be colored, it can be used very suitably for general household use.

Then, for example, in a parking lot or a garage,
When the rear wheel of the reverse-moving vehicle comes into contact with the wheel receiving surface (2), the wheel tire (T) first comes into contact with the lower contact surface portion (2b) that extends forward of the wheel receiving surface (2), and then the cushion. Next (FIG. 4), after a short time, the rolling contact of the wheel tire (T) is stopped by contacting the upper contact surface portion (2a) (FIG. 5). As described above, the contact of the wheel tire (T) is performed in two stages, so that the impact at the time of contact is effectively dispersed. Further, since there is a void due to the recessed portion (3) between the upper and lower contact surface portions (2a) and (2b), the contact impact is also absorbed and dispersed by this void. Therefore, the wheels can be stopped with less shock caused by the contact. In the case of a strong hit, the wheel tire (T) comes into close contact with the recessed portion (3) between the upper and lower contact surface portions (2a) and (2b) (Fig. 6), and the contact includes the surface of the recessed portion. It will be done in three steps and can be stopped more strongly.

When the wheel tire (T) is brought into contact with the tire (T),
The lower contact surface portion (2
Since it comes into contact with b) first from above and rides slightly, the wheel stopper (1) is pressed by the weight of the vehicle,
The movement and lifting phenomenon are prevented, and then the wheel tire (T) comes into contact with the upper contact surface portion (2a), so that a strong force acts on the bonding portion to the ground or floor surface or the fixing portion with the bolt. Therefore, peeling, movement or damage can be prevented. In addition, it is not necessary to extend the plate-like portion on which the wheel rides forward as in the conventional case.

[0029]

As described above, according to the wheel stopper of the present invention, it is possible to easily and cost-effectively manufacture the synthetic resin by molding, and it is far better than the conventional concrete or metal. It is lightweight and easy to handle, has excellent durability, and can be easily and suitably used for general household use. Moreover, the shape characteristic of the wheel receiving surface, that is, the shape in which the upper and lower abutting surface portions of the wheel receiving surface are brought into contact with each other in two steps, particularly from the lower side, can alleviate the shock at the time of contact, and the lower side contact. By the pressing action of the wheel tire on the contact surface portion, it is possible to effectively prevent the inclination, peeling or movement due to the contact of the wheel tire. In addition, a strong force does not act on the fixing portion by the bolts and nuts, and damage from this portion can be prevented. Further, since the recessed portion does not have the horizontal and vertical portions between the upper and lower contact surface portions, the tire comes into close contact with the surface of the recessed portion when the vehicle enters at a high speed, so that the tire can be stopped more reliably. .
