Abstract:
An infinite door check mechanism for enabling a door to be moved from a closed position in a door frame to any one of a plurality of different open positions and held in the different open positions, comprising:a rack adapted to be coupled to and extend outward from the frame; a gear adapted to be arranged on the door, said gear having teeth and being arranged in engagement with said rack; a cam having a pawl arranged to selectively engage with said rack; a detent arranged on said cam; and a spring arranged on said cam for biasing said detent against said gear to thereby press said gear against said rack and prevent rotation of said gear relative to said cam when a force exerted on the door is less than a threshold and allow rotation of said gear relative to said cam when the force exerted on the door is greater than the threshold whereby rotation of said gear relative to said cam enables the door to be positioned in a plurality of positions relative to said rack.
