Claims

[Scope of claim for utility model registration] The main body of the door check that is attached to the door,
The door check has a first link whose base end is connected to the main body, a second link whose base end is connected to the fitting frame, and the tips of the first link and the second link are rotatably attached to each other. A ratchet pawl attached to the door check body and an arcuate plate fixed concentrically with the axis of the base end of the first link, the door at the circumference of the plate being fully opened from the fully closed state. A ratchet tooth is formed in an area where the ratchet pawl can come into contact during the previous operation, and the ratchet pawl is placed in contact with the ratchet tooth at a position in the circumferential portion that will come into contact with the ratchet pawl when the door comes to the fully open position. A control plate formed with a cam that rotates the ratchet pawl to a non-meshing position where the tooth is disengaged, a spring that urges the ratchet pawl to a meshing position where the ratchet pawl meshes with the ratchet teeth, and a detent mechanism that maintains the non-meshing position of the ratchet pawl. A door check.
