Title:
DOOR HARDWARE NOISE REDUCTION AND EVALUATION
Document Type and Number:
WIPO Patent Application WO/2019/032673
Kind Code:
A3
Abstract:
An exemplary noise-reducing mechanism for door hardware includes a housing, a damper, and a stop. The door hardware includes a first component and a second component, and an operational movement of the door hardware causes relative movement of the first and second components. The housing is mounted to the first component, and the damper is mounted to the housing. The stop is mounted to the second component such that the stop engages the damper during the operational movement. The damper is configured to slow the operational movement, thereby reducing noise generated by operation of the door hardware.
