Door Mechanism that Permits Easy Opening and Holds Door Open
A door support includes a first shaft coupled to a door for rotating the door; a first armature on the first shaft; a second shaft with at least one module that resists motion; a second armature on the second shaft; a linkage that connects the armature on the first shaft with the armature on the second shaft; a freewheel on the second armature or on the second shaft that does not engage the module that resists motion thereby allowing the door to open without resistance, the freewheel engaging as the door is closed to provide a resistance as the door is closed, and the linkage positioned such that as the door is nearly closed that the resistance becomes negligible allowing the door to fully close.
