Universal Escutcheon Mounting Plate with Adjustable Slots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing escutcheon mounting systems lack universality, requiring multiple plates for different lock types due to varying hole spacings and sizes, making them inflexible and time-consuming to install, especially when retrofitting existing doors.
Innovation Solution
A universal mounting plate with adjustable elongated slots and a central aperture, allowing for flexible positioning of fasteners to align with existing door holes, compatible with both tubular and mortise locks, and exit devices, eliminating the need for custom hole patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple mounting plates are used for different lock types, then compatibility with various door hardware is improved, but device complexity and inventory requirements increase
Solution Approach 1:
The mounting plate is designed with a universal pattern of holes that can accommodate multiple types of door hardware including mortise locks, tubular locks, and exit devices. The plate includes a top pair of holes, a bottom pair of holes, and a center hole arranged in a configuration that can adapt to different lock types through selective use of fasteners at different hole positions, eliminating the need for multiple specialized mounting plates
Solution Approach 2:
The mounting plate incorporates adjustable fastener positions through elongated slots and multiple hole patterns that allow the fasteners to be repositioned along the plate. This dynamic adjustment capability enables the same mounting plate to accommodate varying hole spacings and configurations required by different lock types, providing flexibility without requiring multiple fixed-pattern plates
2Manufacturing precision
If custom hole patterns are drilled for each lock type, then precise alignment with door hardware is improved, but installation time and difficulty increase
Solution Approach 1:
The mounting plate is pre-manufactured with a universal pattern of holes and elongated slots that are strategically positioned to accommodate multiple lock types. This preliminary preparation of the hole pattern eliminates the need for on-site drilling and custom hole creation, allowing installers to simply align and fasten the plate to the door hardware
Solution Approach 2:
The mounting plate serves as an intermediary component between the door hardware and the escutcheon. It includes a pattern of holes and slots that act as a mediator, translating the varying requirements of different lock types into a standardized mounting interface, thereby simplifying the installation process while maintaining precise alignment
3Adaptability or versatility
If multiple mounting plates are inventoried for different lock types, then compatibility is improved, but inventory costs and complexity increase
Solution Approach 1:
A single universal mounting plate design replaces the need to maintain inventory of multiple specialized plates. The plate's hole pattern and slot configuration enable it to serve multiple functions across different lock types, reducing inventory requirements from several variants to one standardized component
Solution Approach 2:
The invention merges the functionality of multiple specialized mounting plates into a single universal plate. By combining the hole patterns and slot configurations that would otherwise require separate plates for mortise locks, tubular locks, and exit devices into one integrated design, the inventory burden is consolidated

AI summary
A mount is provided for securing an escutcheon on a door. The mount comprises a plate member having a central aperture and an upper pair of elongated slots and a lower pair of elongated slots. Each of the elongated slots extends parallel to a central longitudinal axis of the plate member. A mounting stud is slidably received in at least one of the upper pair of elongated slots and the lower pair of elongated slots for positioning of the stud relative to the central aperture, wherein the studs can be located at selected distances from the central aperture for alignment with a hole through the door.
