Door closer with dynamically adjustable latch region parameters
First Claim
1. A controller for a door closer comprising:
- a position sensor to determine a position of a door;
a memory to store settings to control a single valve for operating the door closer in a latch region for the door;
control circuitry including a connection for a motor to control the single valve in the door closer, the control circuitry functionally connected to the position sensor and the memory, the control circuitry operable to dynamically and automatically adjust at least a latch region definition from among the settings stored to control the single valve for operating the door closer in the latch region when the door does not reach jamb upon closing to increase a likelihood of the door closer causing the door to reach jamb upon closing; and
a device to provide electricity to power the controller.

Abstract
A door closer with dynamically adjustable latch region parameters is disclosed. Embodiments of the present invention include a door closer with a control unit to intelligently control a valve to vary the operating characteristics of the door closer as needed. The control unit can repeatedly determine whether a door has reached jamb upon closing. A setting or settings for the latch region of the door can be adjusted when the door does not reach jamb. These adjustments are such that the likelihood of the door reaching jamb upon closing is increased. Jamb successes can also be monitored, so that once there have been enough successful closes, settings can be adjusted to decrease the force on the door so that the latch region parameters are constantly adjusted for changing conditions to achieve closing success with the minimum closing force necessary.

10. A door closer comprising:
-
a spring; a movable element configured to move in response to movement of a door, the movable element loading the spring; a single valve configured to control movement of hydraulic fluid around the movable element; a motor connected to the valve; a position sensor to determine a position of the door; a memory to store settings to control the single valve for operating the door closer in a latch region for the door; control circuitry connected to the motor, the memory and the position sensor, the control circuitry operable to dynamically and automatically adjust at least a latch region definition from among the settings stored to control the single valve for operating the door closer in the latch region when the door does not reach jamb upon closing to increase a likelihood of the door closer causing the door to reach jamb upon closing; and a device to provide electricity to power the control circuitry, the memory, and the position sensor. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
