Quick-Release Mounting Fitting for Tool-Free Seat Track Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting systems for objects, such as vehicle or aircraft seats, require multiple fasteners and tools for adjusting and securing positions, which is time-consuming and labor-intensive.
Innovation Solution
A mounting fitting with a quick-release mechanism using a push-button and spring-biased locking system that allows easy locking and unlocking of the fitting to a track without tools, utilizing a ball and groove mechanism for secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional fasteners (screws, bolts) are used to secure the fitting to the track, then the mounting is secure and reliable, but the process requires multiple parts, tools, and significant time and labor for fastening and unfastening
Solution Approach 1:
The patent merges the functions of multiple separate fasteners into a single integrated locking mechanism. The locking mechanism includes a body with a locking element that can engage with the track in multiple positions, replacing what would traditionally require multiple screws or bolts. This consolidation reduces the number of parts and simplifies the operation while maintaining secure mounting.
Solution Approach 2:
The locking mechanism is designed to be self-servicing through its spring-loaded locking element that automatically engages with the track when the fitting is inserted. The spring bias ensures the locking element maintains constant pressure against the track, providing automatic securing without requiring additional tools or manual fastening operations.
2Reliability
If multiple fasteners are used to secure the fitting, then the mounting is reliable, but the process is time-consuming and labor-intensive
Solution Approach 1:
The locking mechanism employs a dynamic spring-loaded locking element that can quickly transition between engaged and disengaged states. The spring provides rapid response when force is applied to the release element, enabling fast unlocking without the gradual unscrewing or unfastening required by traditional fasteners. This dynamic action maintains reliability through positive engagement while dramatically reducing the time required for mounting and dismounting operations.
3Ease of operation
If a simple push-button mechanism is used, then the operation is quick and easy, but the locking reliability may be compromised
Solution Approach 1:
The spring acts as an intermediary between the push-button release element and the locking element. When the button is pressed, the spring controls the timing and force of the locking element's disengagement, ensuring reliable unlocking. Conversely, when the fitting is installed, the spring ensures the locking element firmly engages with the track, providing reliable locking. This intermediary mechanism bridges the simplicity of the button interface with the reliability of positive mechanical engagement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables rapid repositioning of seats along tracks without tools, simplifying the adjustment process and reducing time and labor requirements.
Implementation Method 1
the locking mechanism includes a housing within which is mounted a push-button on a spring, the spring biasing the push-button relative to the housing to extend from an opening in the housing
Implementation Method 2
The quick-release mechanism may include a ball arranged to travel around a groove in the push-button and a complementary groove in the housing

AI summary
A mounting fitting includes an elongate fitting body having a first portion configured to be attached to the object and a second portion having a locking mechanism configured to releasably lock the mounting fitting. The locking mechanism includes a housing including a push-button on a spring, where the spring is biasing the push-button relative to the housing to extend from an opening in the housing, in an unlocked position, and where the button has one or more legs extending into the housing. The legs may be configured to extend from the housing, in a locking position, when the push-button is pressed against the force of the spring for engagement, in use, with the surface. The elongate fitting body further includes a quick-release mechanism between the push-button and the housing configured to lock the button in the locking position and to release the button from the locking position.
