Why can't the hotel window be completely pushed open?

Because for the sake of protecting guests' safety, the windows of hotel rooms are usually equipped with stops, which will limit the opening angle and width of the windows: generally, the opening angle is allowed to be 15 degrees, and the relative width is less than 20cm.

The main purpose of this design is to protect the safety of high-rise guests and avoid accidental falls. Anti-theft on the low floor ensures the safety of guests' property. At the same time, it also saves the cost of installing protective fences and anti-falling nets, and saves the cost of hotel safety protection.

In addition, the hotel will control the slope below 12 degrees when designing, which is the routine design for the disabled. If the slope is too high, it is not suitable for wheelchairs, and the value less than 12 degrees can facilitate the implementation of wheelchairs. As you can see, there will be a small slope next to the stairs, which is the disabled passage.

Don't play around on that slope, it's disrespectful to the disabled. No matter in the hotel or in the Grand Duke's place, there are such designs. The greatest respect for disabled people is that they don't need help to travel by themselves. A simple slope design can make them get great satisfaction and respect.
