Infinite check link system

摘要

A check system for selective movement between a frame and a door includes a link attached to one of the door and the frame, and a housing attached to the other of the door and the frame. The link defines a link friction surface. The housing defines a tunnel through which the link is selectively movable and a first housing ramp formed at an acute angle relative to the link. A friction plate is disposed within the housing, and defines a first plate ramp slidably engaged with the first housing ramp. The friction plate also defines a plate friction surface configured for contact with the link friction surface. A biasing member is operatively attached to the housing and biases the friction plate toward the link and the first housing ramp.

1. A check system between a frame and a door, comprising:
a link attached to one of the door and the frame, and defining a link friction surface; a housing attached to the other of the door and the frame, and defining a tunnel through which the link is selectively movable and a first housing ramp at an acute angle relative to the link; a friction plate disposed within the housing, and defining a first plate ramp mirroring the first housing ramp and a plate friction surface in selective contact with the link friction surface, such that contact creates friction between the plate friction surface and the link friction surface; and a biasing member operatively attached to the housing and biasing the friction plate toward the link and the first housing ramp, wherein movement of the link relative to the housing causes movement of the friction plate relative to the housing, which moves the first plate ramp up the first housing ramp and reduces the friction between the plate friction surface and the link friction surface.
