DOOR ACTUATOR
First Claim
Patent Images
1. An apparatus comprising:
- a power boost package configured as an attachable module for use with a spring-damper door actuator to move a door including a chassis and having a portion configured to be in power communication with the door actuator for movement of the door, the chassis of the package forming a structure to retain;
an actuation member structured to contribute a power in the movement of the door; and
an energy storage device capable of being energized by movement of the actuation member, the energy storage device operable to store a boost energy as a result of a first movement of the actuation member, and configured to release the boost energy at a release position of the actuation member, the boost energy released through the actuation member as a result of a second movement of the actuation member.

Abstract
A power boost assembly is disclosed that can be used with a door actuator, such as a door closer. The power boost assembly is structured to store an energy during a first movement of a door and release the stored energy during a second movement of the door. In one form the power boost assembly can be structured as a module that can be added to an existing door and door closer installation. In one form the power boost assembly is used to increase a closing force imparted to a door to ensure a latching event.

12. An apparatus comprising:
an add-on supplemental door actuation module having an outer housing structured for engagement to a door closer device and having an actuator configured to be in force communication with the door closer device, the add-on supplemental module structured to activate an energy storage device of the actuator to store an energy along a swing of a door when the door closer is actuated in a first direction and structured to maintain the stored energy via a power modulator of the actuator when the door closer is actuated in a second direction until the door reaches a boost location wherein the stored energy is released from the actuator to deliver a boost to a door to supplement the door closer device. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
