Abstract
A hardwood floor system with press down locking mechanism. Each floor board is equipped with both male and female locking mechanisms. The male locking mechanism of a floor board can be locked into the female locking mechanism of an adjacent floor board by simply exerting downward force on the floor board. The female locking mechanism is equipped with a spring slot that enables easy engagement of male and female locking mechanisms. The invention may be applied not only floor boards, but also to wall tiles and roof tiles.
