Claims

[Scope of utility model registration request]

A floor hinge rotatably supporting the lower end of a door,
A vertical main shaft connected to the lower end of the door is provided at one end in the width direction of the floor hinge body, and a lever is rotatably provided with a gear that engages with teeth formed on the outer peripheral surface of this main shaft. A transmission means is provided to apply a spring force that acts to bias the door in the direction of closing the door, and further, the rotation of the main shaft is stopped at a predetermined angle (a transmission means that can be fitted with a protrusion provided at an appropriate position on the outer circumference of the lever) is provided. A floor hinge provided with a locking means and an operating shaft for displacing the locking means between a position where it fits into the protrusion and a position away from this position.
