Lock Striker Assembly With Hidden Retaining Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing strikers for locks are difficult to assemble and disassemble, aesthetically unattractive, and require additional components to cover visible fixing means, leading to increased complexity.
Innovation Solution
A striker design with a receiving body and retaining element that uses interchangeable sliders and arresting means for secure assembly and disassembly, eliminating visible fixing elements and allowing for easy installation on hollow profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional fixing means (screws, threaded fasteners) are used to secure the striker to the frame profile, then the striker can be reliably fixed in place, but the fixing means become visible on the front face of the striker, making it aesthetically unattractive and requiring additional covering elements
Solution Approach 1:
The invention extracts the fixing function from visible external fasteners and relocates it to an internal retaining element that operates within the striker body. The retaining element can be actuated from the rear face to engage or disengage fixing tabs from the hollow profile, completely hiding all fixing mechanisms from the front face and eliminating the need for aesthetic covering elements.
Solution Approach 2:
The invention introduces a retaining element as an intermediary mechanism between the operator and the fixing function. This retaining element, actuated by a tool inserted through a rear opening, mediates the engagement of fixing tabs with the profile, providing both aesthetic coverage and a controlled fixing mechanism that prevents component loss during maintenance.
2Reliability
If multiple fixing means and movable sliders are used to secure the striker in the frame seat, then the striker can be reliably fixed, but assembly and disassembly become difficult and time-consuming, especially for non-specialist personnel
Solution Approach 1:
The invention segments the fixing function into separate fixing tabs on the striker body that can independently engage with the hollow profile. The retaining element controls these tabs, allowing them to be engaged or disengaged as a group through a single actuation action from the rear, simplifying the operation while maintaining reliable fixing through multiple contact points.
Solution Approach 2:
The invention inverts the traditional approach by providing access to the actuating mechanism from the rear face rather than the front. The opening on the rear face allows insertion of a tool to actuate the retaining element, reversing the conventional wisdom that controls should be accessible from the front, thereby simplifying front-face operations while maintaining reliable fixing.
3Ease of manufacture
If the striker requires covering elements to hide visible fixing means, then aesthetics are improved, but the number of components increases and construction complexity increases
Solution Approach 1:
The invention extracts the aesthetic covering function from separate external elements and integrates it into the main striker body structure. The front face is designed as a continuous aesthetic surface with no openings or visible fasteners, while the fixing function is extracted to internal tabs actuated from the rear, eliminating the need for separate covering elements and reducing component count.

AI summary
A striker (10) for locks, comprising a receiving body (20) having a cavity (20") formed on a front face (20a) adapted to receive a closure member along an insertion direction (Z), and a lateral surface (20b); a retaining element (30) positioned in a seat (22) of said receiving body (20) and movable between an extracted position, corresponding to an engagement configuration in which said striker (10) is secured in a seat of a frame, and a retracted position, corresponding to a release configuration in which said striker (10) is extractable from said seat. Wherein the striker (10) further comprises an adjustment member (50) insertable into said receiving body (20) and operatively associated with said retaining element (30); said adjustment member (50) being configured to be actuatable from inside the cavity (20") along a direction transverse to said insertion direction (Z), so that said retaining element (30) is activated along a direction of movement (Y) transverse to said insertion direction (Z).
