Abstract
A door closer is provided to automatically pull a storm or screen door to a fully closed position without user action. The door closer includes a bracket housing with a cam switch movable along a track as the door opens and closes. The closer cylinder rod is engaged with the cam switch until the door is fully opened. The cam switch biases the closer cylinder and rod as the door approaches the closed position.
Claims22
A door closer assembly for a storm or screen door movable between opened and closed positions relative to a door frame, comprising:
- a bracket attached to the door frame;
- a cylinder and rod assembly having a first end extending into the bracket and a second end adapted to be attached to the storm door;
- and
- the bracket including a spring to apply a force to the storm door to pull the storm door to a closed position.
A door closer assembly for a storm or screen door hinged to a door jamb, the assembly comprising:
- a bracket fixed on the door jamb;
- a cylinder fixed to the storm door;
- a rod having opposite first and second ends extending between the cylinder and the bracket and being extensible and retractable relative to the cylinder to allow the door to open and close;
- a cam on the bracket and operatively connected to the rod to urge the rod to a retracted position to pull the door closed.
A method of closing a storm door hinged to a door frame, comprising:
- retracting a linear actuator having a first end connected to the storm door and a second end connected to a bracket mounted on the door frame so as to move the storm door from an open position to a substantially closed position;
