Spring-Mounted Slide Lock for Tool-Free Rack Component Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for securing rack rails to electronics racks are either cumbersome due to the use of mechanical fasteners or unreliable due to reliance on gravity, lacking an efficient and easy-to-use locking mechanism, especially in tight spaces.
Innovation Solution
A slide locking mechanism with a spring-mounted support base and release lever that securely attaches to a flat flange portion of the rack rail, featuring a locking latch and a spring to bias the mechanism toward the end of the rail, allowing for easy installation and removal without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If mechanical fasteners such as bolts are used to secure rack rails, then the connection strength is improved, but the ease of operation deteriorates due to the need for tools and time-consuming installation
Solution Approach 1:
The patent replaces the traditional mechanical fastening system (bolts, screws, and other threaded fasteners requiring tools) with a spring-loaded cam locking mechanism. The cam lever, when actuated, forces the locking latch through the slot in the flange portion, creating a secure mechanical interlock with the mounting rail without requiring any threading or tool operation. This substitution maintains connection strength while dramatically improving ease of operation.
Solution Approach 2:
The spring-loaded mechanism provides self-service functionality by automatically maintaining locking pressure and enabling easy release through simple lever movement. The spring continuously biases the locking latch against the mounting rail surface, ensuring constant engagement force without requiring adjustment or maintenance. For release, the user simply moves the cam lever to the released position, allowing the spring to retract the locking latch from the slot, enabling quick tool-free installation and removal.
2Ease of operation
If gravity-based static hook systems are used to hold rack rails, then the ease of operation is improved, but the reliability deteriorates due to the risk of inadvertent dislodgement
Solution Approach 1:
The spring-loaded mechanism acts as a counterweight force system, where the spring continuously applies forward biasing force on the locking latch to maintain positive engagement with the mounting rail slot. This active spring force counteracts any gravitational or vibrational forces that might otherwise cause the rail to dislodge, providing reliable retention while maintaining easy operation through the cam lever release mechanism.
3Ease of operation
If a pivotable latch system is used for securing rack components, then the ease of operation is improved, but the adaptability deteriorates because the latch may not work in tight locations
Solution Approach 1:
The patent employs a dynamic locking mechanism where the cam lever can be actuated through a limited arc to transform the locking state. The cam lever's rotational movement dynamically converts small user input motion into the linear displacement needed to engage or disengage the locking latch from the slot. This dynamic action requires minimal space and can be actuated even in tight locations where a full pivotable latch would not fit, while still providing easy one-handed operation.

Function Achieved in This Case
Provides a reliable, tool-free, and efficient method for securing rack rails to electronics racks, accommodating various rail and post thicknesses, ensuring secure attachment and easy detachment without the risks associated with gravity-based systems.
Implementation Method 1
A spring is mounted to or formed on the body and engages with the component so as to bias the slide lock toward the end of the component
Data Source
AI summary
An electronics rack component including at least one slide locking mechanism for removably securing the component to a rack. The slide lock mechanism includes a slide lock with a support configured to slide along a flat flange portion of the rail. A release lever protrudes from the top surface of the support base and provides a structure or surface for a user's finger to slide the support base along the flat flange portion. A locking latch extends downward from the bottom surface of the base and through the slot in the rail. The locking latch includes a portion spaced apart from the bottom surface of the base a distance to accommodate the flat flange portion and a flange on the electronics rack. A spring biases the slide lock toward the end of the component.
