BACKGROUND OF THE INVENTION
The present invention relates to an automobile tire stop block made of a plastic hollow molded article.
[0002]
[Prior art]
As shown in FIG. 9, conventionally, a tire retaining block (1P) for automobiles is a concrete tire retaining block (1P) having a constant height H (patent). Reference 1).
In general, the length LP of the concrete tire stop block (1P) is set to 600 mm, and the height H of the tire stop block (1P) is set to 120 mm. Further, the width W1 of the parking space is usually 2500 mm, the width W2 of the tire of the automobile is 200 mm, and the distance W3 between the tires is 1300 mm. Therefore, when installing a pair of tire retaining blocks (1P) in the parking space, if the distance l from the side edge of the parking space to the outer end of the tire retaining block (1P) is set to 300 mm, the tire retaining block (1P) A gap S of 700 mm is generated between them (see FIG. 7 ).

[Problems to be solved by the invention]
However, since the conventional tire stop block (1P) has a gap S of 700 mm between the tire stop blocks (1P), when the vehicle is parked, particularly when reversing and parking, If there is a slight mistake, there is a problem that the tire of the automobile slips through the gap S between the tire stopping blocks (1P).
Therefore, in order to prevent such slipping of the tire, it is conceivable to install another tire retaining block (1P) in the gap S between the pair of tire retaining blocks (1P). In such a case, there is a problem that installation work of the tire stop block (1P) requires a lot of labor and labor, and the installation cost is also greatly increased.
In order to prevent the tire from slipping through as described above, it is conceivable to increase the length LP of the tire stop block (1P). In this case, however, the weight of the concrete block (1P) increases significantly. However, there was a problem that the handling property at the time of installation work was lowered.
[0005]
In addition, since the conventional tire stop block (1P) has a constant height H, the mounting height of the muffler, etc. is also set low especially in the case of an automobile with a low vehicle height. There is a problem that a part of the vehicle body such as a muffler may come into contact with the tire stopping block (1P).
Furthermore, when the tire stop block (1P) is made of concrete, there is a problem that the vehicle body is often greatly damaged when a part of the vehicle body such as a muffler comes into contact with the tire stop block (1P). there were.
Therefore, in order to prevent contact with a part of the vehicle body such as a muffler, it may be possible to lower the height H of the tire retaining block (1P), but if the height H of the tire retaining block (1P) is decreased. When parking, there is a problem that the tire of the automobile easily gets over the tire stop block (1P), and the vehicle stop function is lowered.
