Description

Description: FIELD OF THE INVENTION The present invention relates to a bicycle erecting prevention plate for laying on a road surface, particularly a place where a bicycle should not be parked.

[Conventional Technology and Disadvantages] Unsolicited bicycle parking has become a major social problem in front of stations and the like. This bicycle parking is for coming to the station by bicycle and commuting to school by train.

This number is extremely large, which not only greatly hinders walking in front of the station, but also greatly affects nearby shops.

To prevent this, signs such as banning bicycle parking have been erected by the station manager or police chief, but this has little effect.

In addition, if a rope or the like is set up, it cannot pass therethrough, and it is meaningless because it interferes with walking.

Thus, there has been a long-awaited need for a method and apparatus that does not hinder pedestrians' walking and does not park bicycles.

[Means for Solving the Problems] In view of the current situation as described above, the present inventor has completed the plate of the present invention as a result of earnest research, and the feature of the plate is that a synthetic resin laid on a road surface is provided. The plate is made of a plate, and at least on one surface thereof, a large number of mountain-shaped projections having a height of 1 cm or more and having a sharp or curved tip portion are randomly arranged at intervals of 1 cm or less.

The inventor of the present invention has conducted various studies on a method of not parking a bicycle, and as a result, has recognized that a normal method cannot prohibit parking. He eventually realized that if the bicycle did not stand upright, there would be no way to park it. However, if the bicycle cannot be stopped but pedestrians cannot pass, there is no point in eliminating the bicycle, so we considered the condition that walking is not hindered. As a result of various studies on the condition that these two points, that is, the bicycle does not stand upright and there is no obstacle to walking, the present invention has been completed.

In order to stand upright, the center of gravity must be located within the triangle formed by the left and right ends of the stand and the front wheels. Therefore,
To avoid erecting the bicycle, tilt the bicycle so that the center of gravity does not enter this triangle. The present invention has been made from this point of view, and is configured such that there is always a height difference between the left and right ends of the stand.

The plate generally refers to a plate, but here also includes a block such as an interlocking block. The size is not limited, but it is 20-30
A square cm is preferable. The thickness may be thin except for the protrusion.

This plate is made of a synthetic resin, but if it is thick, the lower portion may be made of an inorganic material such as cement. When it is thin, an adhesive layer may be provided on the back surface so as to be easily attached to the road surface. The synthetic resin may be hard, but if it is made of soft rubber, there is an effect that the bicycle is more likely to fall.

The mountain-shaped projection is for preventing the bicycle from standing upright by losing the smoothness of the road surface. Therefore, the height is at least 1 cm or more, and 5 cm or more is meaningless. In addition, in order to make the left and right ends of the stand have a height difference, one must be located on the projection and the other must be located in the groove formed by the projection.

For this reason, the tip of the projection is configured to prevent the end of the stand from falling, that is, to have a flat or concave shape. However, if the left and right ends of the stand are both located on the projection, no difference in elevation can be made, and the stand will not fall.
In order to prevent this, the projections are provided randomly. There is no limitation on this shape.

Furthermore, since it is necessary to prevent both the left and right ends of the stand from being located in the groove, it is necessary to provide a relatively large number of projections, and the interval between them must be 1 cm or less.

With such protrusions, the pedestrian will notice the protrusions, but there is almost no problem in walking and there is no problem.

Embodiment FIG. 1 is a perspective view showing an example of the plate of the present invention.

The bicycle upright prevention plate 1 (hereinafter simply referred to as “plate 1”) includes a bottom plate 2 and a projection 3.
The bottom plate 2 has a thickness of 5 mm, and the protrusion 3 has a columnar shape and a height of 10 m.
m, diameter 10 mm. The plate 1 is made of polyvinyl chloride, and the bottom plate 2 and the projection 3 are integrally formed. The projections 3 are randomly arranged on the bottom plate 1, and one side of the bicycle stand is always in contact with the bottom plate 2, and the other side is always on the projection 3.

FIG. 2 shows the bicycle stand 4 on the plate 1 of FIG.
FIG. Left and right ends of stand 4
There is a height difference between 41 and 42, and the center of gravity is outside the stand, so the bicycle cannot stand alone.

FIG. 3 is a schematic perspective view showing that the example of FIG. 1 is laid on a part of the passage. Generally, it is laid at both ends of a passage that is easy to park, and not at the center. In the case of this example, an adhesive is applied to the back surface of the plate 1 and is adhered on the existing pavement. The lower portion is made of concrete, and the same procedure as the concrete block or the interlocking block is used. May be laid. [Effects of the Invention] As described above in detail, the bicycle erecting prevention plate according to the present invention is a synthetic resin plate laid on a road surface and has a height of 1 cm or more on at least one surface thereof. In the present invention, a large number of mountain-shaped protrusions having a flat or concave shape at the tip portion are randomly and randomly arranged at intervals of 1 cm or less, and have very high altitudes having various effects as described below. Invention.

Even if you try to park a bicycle, you will have to give up because you can not stand alone, so that annoying bicycle parking can be resolved as a result.

A large number of projections with flat or concave tips are arranged at intervals of 1 cm or less, so that they do not hinder walking.

Just by laying, the bicycle independence prevention area can be completed on the pavement, so it is possible to prevent annoying bicycle parking at low cost.
