Description

A Parasol for crosswalk}

The present invention relates to a parasol installed to avoid sunlight or snow when a pedestrian waits for a signal to cross a pedestrian crossing. More specifically, the parasol is separated into two stages, It provides a cozy space that is cooler and avoids rain. In the nighttime, the light is lit inside the umbrella so that it can maintain a bright atmosphere without being dark, so that the pedestrian can use it safely.

Generally, pedestrians are waiting for a long period of time at the crosswalk of a street, and there is no space to provide shade to avoid snow or rain or to avoid intense sunshine, so that pedestrians are exposed to direct sunlight and high temperatures during a long wait, And so on.

Recently, in each municipality, a shade tent or a parasol is installed in the waiting space formed in the entranceway of the pedestrian crossing to partially solve the inconvenience of pedestrians passing through the pedestrian crossing.

Conventional techniques related to the present invention include Patent Documents 1 to 4, wherein the parasol for a crosswalk according to the related art is formed by attaching one parasol to one pillar, thereby preventing sunlight or snow. In the case of using a waterproof fabric, there is a problem that the air permeability is lowered, and the temperature of the lower part of the parasol rises due to the increase in the temperature of the parasol, thereby causing a discomfort. In the case of using the ventilated fabric, the air permeability is good but the waterproofness is poor.

In addition, a conventional parasol for a pedestrian crossing has a disadvantage that it gives a dark feeling because the parasol under the parasol is not received by the streetlight at night.
