Abstract
A door anti-latch device includes a base mounted to a door or a door frame, and a lever rotatably mounted to the base so that the lever can rotate about a pivot point from an open position to a latching position. The lever includes a handle end and an opposing stop end. The lever can be rotated between the open position and the latching position by moving the lever handle. The lever stop prevents the door from latching when the lever is in the open position and will not prevent the door from latching when the lever is in the latching position. The door anti-latch device can be moved from the open position to the latching position without leaving the room or opening the door.
Claims20
A door anti-latch device for preventing a door from latching, the device comprising:
- a base;
- means for mounting the base to a door or a door frame;
- and
- a lever rotatably mounted to the base so that the lever can rotate about a pivot point from an open position to a latching position, the lever including a handle and an opposing stop end;
- wherein the lever can be rotated between the open position and the latching position by moving the lever handle;
- and
- wherein, when the base is mounted to the door or door frame, the lever stop will prevent the door from latching when the lever is in the open position and will not prevent the door from latching when the lever is in the latching position.
A door anti-latch device for preventing a door from latching with a door frame, comprising in combination:
- a base mounted to the door or the door frame;
- and
- a lever rotatably mounted to the base so that the lever can rotate about a pivot point from an open position to a latching position, the lever including a handle and an opposing stop end;
- wherein the lever can be rotated between the open position and the latching position by moving the lever handle;
- wherein the lever stop end contacts the door frame or the door and prevents the door from latching when the lever is in the open position;
- and
- wherein the lever stop end does not prevent the door from latching when the lever is in the latching position.
A door anti-latch device for preventing a door from latching, the device comprising:
- a base plate defining a pivot point and including a flange opposite the pivot point for contacting an edge of a door or door frame;
- means for mounting the base plate to the door or door frame, and
- a lever plate including a handle and an opposing stop end and rotatably mounted to the base so that the lever plate can rotate about the pivot point from an open position to a latching position by moving the lever handle;
- wherein the lever stop end engages the door frame or the door and prevents the door from latching when the lever is in the open position;
- and
- wherein the lever stop end does not engage the door or door frame and does not prevent the door from latching when the lever is in the latching position.
