Hi there..
Since my Raycast Tryouts are not working, i wanted to try it with Triggers.
Therefor i created 2 Empty childs to my player, and attached Box colliders to them. Both colliders have "is Trigger" enabled.
As first, i wanted to try the Box, that should check if in the Height of Players head is a wall (wall objects do have a rigidbody with kinematic enabled + box collider).
But wether the Trigger Stay, nor the Trigger Exit are reacting when hitting the Wall Objects.
See this Pictures:

I despair slowly... 
Edit: Nevermind.. needed to give each trigger Object a Rigidbody - not the Walls.
