Warning Apparatus

Abstract

A warning apparatus is provided, whose main body includes a monolithically formed transparent tempered material with a thickness. The top of the main body includes at least two injections units. The injection units are upward bumps. The injection units are less than 10 mm in height. The curvature on the surface of injection unit bumps changes at different height of the bumps. The bottom of the main body includes at least two reflection units. The reflection units are downward bumps. The bottom of the main body also includes a reflective layer attached to the outer surface of the reflection units so that the light entering the main body can be reflected by the reflective layer to provide warning. The durable, low-height injection unit bumps will minimize the impact on the driving safety when the tires run over, while providing effective visual warning.

Description

FIELD OF THE INVENTION[0001]The present invention generally relates to a warning apparatus for traffic roads, and more specifically to a road warning apparatus that has lower surface bump, higher reflective effect, and durable structure.BACKGROUND OF THE INVENTION[0002]The marks on the road surface are for providing the drivers with the visible direction so as to keep proper space between vehicles. The ideal situation is that the marks on the road surface must be able to provide suitable visibility under any circumstances, rain or shine, day or night. FIG. 1 shows a cross-sectional view of a conventional road mark. A conventional road mark 91 is mainly made of thermal-plastic. To reflect light for warning, small glass beads 92 with diameters ranging between 0.1-0.4 mm are added to the thermal plastic. Glass beads 92 can reflect the light from the headlights of the vehicles so that the driver can still see the lane division and the direction of the road when the visibility is low. Ho...

Benefits of technology

[0005]The present invention has been made to overcome the above-mentioned drawback of conventional reflective warning apparatus. The primary object of the present invention is to provide a warning apparatus that is low-height and durable. The warning apparatus of the present invention is monolithically made of a tempered transparent material, such as glass. The warning apparatus has a thickness with the injection unit and the reflection unit at the top and the bottom so as to reflect horizontal lights effectively. The warning apparatus, after installation, is only less 5 mm over the road surface, and will not be immersed by the rain to lose the reflection for warning. As the bump after the installation is low, the warning apparatus will not affect the driving safety and remains to provide effective warning for drivers.

Problems solved by technology

However, when it rains in the evening, the 0.1-0.4 mm glass beads are easily immersed by the rain, and fail to reflect the light properly.

Therefore, the usability of such conventional road marks is impaired.

In addition, the reflective warning apparatus forms a bump on the road surface that may cause discomfort, or even hazard, when the tires run over the reflective warning apparatus, which causes the tire skid or shift.

Another concern is that the reflective warning apparatus may be easily damaged by the snowplow in the snowy area when the roads are covered in snow.

On the other hand, it is difficult to keep the height of the reflective warning apparatus less than 3 mm, as the protective shell for such apparatus, usually made of aluminum alloy or plastics, must be thicker than 3 mm to provide sufficient protection to the apparatus as well as weather the weight of vehicles.

However, in actual application, this design usually suffers the problem of lack of durable strength.

Thus, it is prone to damage or worn out easily by vehicles in a short period of time, and the glass beads may break off to lose the reflectivity.

However, the integration of glass beads and the thermal-plastic road marks is still lack of the fixation strength, and can be easily broken off after a longer period of time of running over by vehicles.
