Door Closer Mounting Plate With Adjustable Spacer Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door closer mechanisms often have varying mounting hole positions due to different manufacturers or models, making it difficult to reuse mounting holes for replacement installations, which can be aesthetically undesirable and complicate installation.
Innovation Solution
A mounting plate with adjustable spacers and cutouts that fit against the frame of the door closer, allowing for flexible alignment with existing mounting holes, and a stepped profile to ensure flush installation without excessive pressure on the door.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If door closers from different manufacturers or models are replaced, then functional requirements are met, but mounting hole positions vary making reuse of existing holes difficult
Solution Approach 1:
The mounting plate is segmented into multiple regions with different hole patterns, allowing selection of appropriate hole configurations for different door closer models. The plate includes a first region with a first hole pattern and a second region with a second hole pattern, enabling adaptation to various manufacturers while maintaining ease of installation by reusing existing holes.
Solution Approach 2:
The mounting plate is designed as a universal component that can accommodate multiple door closer manufacturers and models through its multiple hole patterns. The plate serves multiple functions: providing mounting holes for different configurations, supporting both door closer mechanisms and decorative covers, and enabling reuse of existing mounting holes across different replacements.
2Shape
If decorative covers are used to conceal mounting holes, then cosmetic integrity is improved, but the covers may not fit properly if hole positions vary
Solution Approach 1:
The decorative cover is segmented into a first portion and a second portion, each corresponding to different hole patterns. The first portion is configured to cover mounting holes in a first configuration, while the second portion covers mounting holes in a second configuration, allowing proper fit and cosmetic integrity for different door closer models.
Solution Approach 2:
Different portions of the decorative cover have different geometries and hole-covering configurations tailored to specific mounting hole patterns. The first portion has characteristics optimized for covering holes in the first region, while the second portion has characteristics optimized for the second region, ensuring proper fit and appearance for each configuration.
3Adaptability or versatility
If mounting holes are drilled at different positions for different door closer models, then compatibility is achieved, but the door appearance becomes inconsistent and installation becomes more complex
Solution Approach 1:
Multiple hole patterns are merged into a single mounting plate, allowing the plate to provide appropriate hole configurations for different door closer models while maintaining a consistent mounting location on the door. This combines the adaptability of multiple patterns with the stability of a fixed mounting position, ensuring consistent door appearance.

AI summary
A mounting plate for a door closer mechanism includes attachment points for attaching the door closer mechanism and openings with opposing parallel linear sides for receiving spacers. The spacers are dimensioned to at least partially fit within the openings, with the spacers defining a through slot to allow passage of shaft of a screw or bolt through the slot and openings. The spacers may include a portion overlapping portions of the mounting plate. The mounting plate may have a stepped profile, with the overlapped portions of the mounting plate having a reduced profile compared to at least some other portions of the mounting plate.
