Universal Door Closer Mounting Bracket for Existing Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door closers often require new mounting holes when replacing a worn closer with a different mounting hole-pattern, leading to complex installations, reduced structural integrity, and unsightly exposed holes, which many non-professionals cannot accomplish due to the need for specialized equipment and skills.
Innovation Solution
A universal mounting bracket system that aligns with various pre-existing mounting patterns, allowing for easy installation by using existing holes without drilling new ones, featuring adaptable mounting openings and securing portions that grip the closer housing securely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a door closer with a different mounting hole-pattern is installed, then the closer can be replaced with a new design, but new mounting holes must be drilled and tapped which requires specialized equipment and skills
Solution Approach 1:
The mounting bracket is designed with multiple mounting openings arranged in different patterns, allowing it to accommodate various door closer models and mounting hole-patterns. This universal design enables the same bracket to serve multiple functions across different installation scenarios without requiring custom brackets for each closer model.
Solution Approach 2:
The mounting bracket acts as an intermediary component between the door and the door closer. Instead of directly mounting the closer to the door (which would require drilling new holes), the bracket is mounted to existing holes in the door, and then the closer is mounted to the bracket. This intermediate step eliminates the need for drilling new mounting holes in the door.
2Adaptability or versatility
If a heavy cumbersome adapter plate is used, then some mounting hole-patterns can be accommodated, but the installation becomes more complex and the adapter plate is difficult to handle
Solution Approach 1:
The mounting bracket is divided into multiple components including a bracket body with mounting openings, a securing mechanism with movable securing members, and mounting hardware. This segmentation allows each component to be optimized for its specific function and enables easier handling and installation compared to a single large adapter plate.
Solution Approach 2:
The securing members of the mounting bracket are designed to be movable rather than fixed. This dynamic design allows the securing members to move between a first position for receiving the door closer and a second position for securing it, providing flexibility during installation and adjustment while maintaining a compact form factor.
3Adaptability or versatility
If new mounting holes are drilled and tapped, then the new closer can be mounted, but the structural integrity and aesthetics of the door are reduced due to exposed unused holes
Solution Approach 1:
The mounting bracket is designed to be mounted to the door using pre-existing mounting holes before the door closer is installed. This preliminary action utilizes the existing holes that would otherwise be wasted, giving them a new purpose and eliminating the need to drill additional holes that would compromise the door's structural integrity and aesthetics.

AI summary
A method of installing a replacement door closer assembly including a closer mechanism includes the steps of: (a) removing a previous door closer assembly from a mounting surface of a door or a door jamb; (b) fixing a first mounting bracket on the mounting surface through a first pre-existing mounting hole; (c) extending the closer mechanism of the replacement door closer assembly through the first mounting bracket while aligning a second mounting bracket with at least a second pre-existing mounting hole in the mounting surface; (d) sliding the closer mechanism back toward the first mounting bracket so that the second mounting bracket can be fixed to the mounting surface through the second pre-existing mounting hole; and (e) positioning and securing the closer mechanism between the first and second mounting brackets.
