Dual link door check
First Claim
1. A door check comprising, in combination:
- a check body having an opening, wherein the check body is adapted to pivot with respect to a fixed member over a travel range;
a main link having a first end and a second end opposite the first end, linearly slidable through the opening of the check body in response to pivoting of the check body; and
a second link having a first end pivotably connected to the first end of the main link, in direct contact with the main link and adapted to be pivotably attached to the fixed member at a second end opposite the first end, wherein the second link is pivotable in response to pivoting of the check body, and the first and second ends of the second link are generally collinear with the first and second ends of the main link when the door check is in a closed position.

Abstract
A door check for holding a door in an open position is disclosed, which is particularly useful for thin doors. The door check comprises a check body attached to the door and having an opening. The door check pivots with the door about a first axis. A main link is slidable through the door check opening as the door pivots. A second link is pivotably attached to the main link, and pivotably about a second axis with respect to a rigid member. As the check body pivots about the first axis, the second link pivots about the second axis and the main link translates through the opening in the check body. The main link may have an irregular surface so that a large force may be required to move the door back from the open position to a closed position.

7. A door check comprising, in combination:
-
a check body having an opening, attachable to a door and pivotable about a first axis;
a main link having a first end and a second end opposite the first end, positioned in the opening of the check body; and
a second link having a first end and a second end opposite the first end, pivotably attached to the door at the second end about a second axis different from the first axis, and the first end of the second link is pivotably connected to the first end of the main link;
wherein in response to the check body pivoting about the first axis, the second link pivots about the second axis, and the main link translates through the opening in the check body, and the first and second ends of the second link are generally collinear with the first and second ends of the main link when the door check is in a closed position. - View Dependent Claims (8, 9, 10)
