Abstract
A safety gate has a doorframe, a fence door and a repositioning unit. The doorframe has a base frame, a first side frame, and a second side frame. The repositioning unit is mounted on a bottom of the fence door and has a repositioning recess. The repositioning recess selectively engages a top of the base frame and has two opposite guiding surfaces. When the fence door is open at an angle under 5 degrees relative to the doorframe, one of the guiding surfaces abuts a side of the top of the base frame. Because the guiding surface is curved and inclined relative to the fence door and because a distance between the guiding surfaces is decreased gradually, the guiding surface gradually rotates the fence door to close. As a result, the repositioning unit can close the fence door that is open slightly at a small angle.
Claims20
A safety gate comprising:
- a doorframe having
- a base frame having two ends;
- a first side frame vertically mounted on one of the ends of the base frame;
- and
- a second side frame vertically mounted on the other one of the ends of the base frame;
- a fence door having
- a first side rotatably connected to the first side frame in an axially moveable manner;
- and
- a second side opposite to the first side;
- and
- a repositioning unit mounted on a bottom of the fence door, being adjacent to the first side frame, and having
- a repositioning recess formed in a bottom of the repositioning unit, being elongated along the fence door, communicating with an exterior environment via two ends of the repositioning unit, selectively engaging a top of the base frame and having
- two guiding surfaces facing each other, being curved and inclined relative to the fence door;
- and
- a distance between the guiding surfaces being decreased gradually along a direction from the first side frame to the second side frame, and being decreased gradually from bottom to top.
