Adjustable Strike Assembly Lateral and Leveling Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing strike or keep assemblies face challenges in providing a simple and economical design for easy adjustment on a wide variety of door or window frames with different designs and materials, as they often require specialized tools and are not adaptable to varying frame profiles.
Innovation Solution
The adjustable strike or keep assembly features a faceplate with slots for lateral adjustment and a screw-threaded member for leveling, allowing easy installation and adjustment without special tools, using a backplate with integral projecting portions and a grub screw for contact with the frame, enabling comprehensive adjustment on diverse frame profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a strike or keep assembly is designed to be adjustable on various frame profiles, then adaptability is improved, but device complexity increases
Solution Approach 1:
The strike or keep assembly is divided into two main segments: a faceplate that interfaces with the frame and a backplate that provides mounting functionality. This segmentation allows each component to be optimized independently for its specific function while maintaining overall adaptability to different frame profiles.
Solution Approach 2:
The backplate is designed with multiple projecting portions that can contact various frame profiles, and the faceplate includes slots that accommodate different mounting positions. This multi-functional design enables a single assembly to work across diverse frame types without requiring specialized versions for each profile.
2Ease of operation
If adjustment mechanisms are added to enable lateral and leveling adjustment, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The adjustment mechanism utilizes the mounting fasteners themselves to perform dual functions: securing the faceplate to the backplate and enabling lateral adjustment through slots. The projecting portions of the backplate directly contact the frame to provide leveling adjustment, eliminating the need for separate adjustment devices.
Solution Approach 2:
The slots in the faceplate are designed to allow dynamic adjustment of the faceplate's lateral position relative to the backplate. The projecting portions enable dynamic leveling adjustment by contacting the frame at variable positions, allowing the assembly to be adapted during installation without specialized tools.

AI summary
A strike or keep assembly comprises a faceplate (5), a backplate (6) including a body portion having a planar front face butting up against a planar back face of the faceplate and one or more projecting portions (12) extending rearwardly from the body portion of the backplate into contact with a face (16) of a supporting frame (11), a screw-threaded member (7) in screw threaded engagement with a threaded hole in the faceplate and extending rearwardly for contacting the planar face (16) of the supporting frame, the faceplate including one or more slots for allowing the passage of one or more fasteners (8A) for engaging one or more fastener locations in the backplate to fasten the backplate (6) to the faceplate (5).
