Toolbox Buckling Apparatus Torque Spring Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing buckling apparatuses in toolboxes are prone to failure due to easy removal of pivot shafts and are difficult to assemble, particularly in the snapping unit, which compromises the reliability and ease of use.
Innovation Solution
A buckling apparatus comprising a buckle, a connector with transversely extending levers and external rods, and an elastic element with torque springs that biases the buckle and connector, enhancing the locking mechanism and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pivot shaft is inserted in a C-shaped hole to connect the pivotal member, then the buckling apparatus can be assembled, but the pivot shaft can easily be removed causing failure
Solution Approach 1:
The patent combines the pivot shaft connection with the torque spring assembly into a single integrated operation. The pivot shaft passes through both the C-shaped hole and the torque spring simultaneously, so that one assembly action accomplishes both the structural connection and the elastic element installation, eliminating the need for separate assembly steps
2Ease of manufacture
If the pivot shaft must be inserted in two individual torque springs, then the torque springs can be installed, but the assembly process becomes troublesome
Solution Approach 1:
The patent positions the torque spring on the pivot shaft in advance during the assembly process. The torque spring is pre-placed on the shaft before final assembly, so that when the connector is inserted, the elastic element is already in position, eliminating the need for separate torque spring installation steps and reducing assembly errors
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
The solution provides a reliable and inexpensive buckling apparatus that securely locks the toolbox while being easier to assemble, ensuring the tools are kept safely closed and can be opened with ease.
Implementation Method 1
The first torque spring is located between and connected to the levers and adapted for biasing the buckle from the connector
Implementation Method 2
The second torque spring is supported on the first lever and adapted for biasing the connector from a toolbox

AI summary
A buckling apparatus includes a buckle, a connector and an elastic element. The buckle includes two bores. The connector includes a main axle, two levers transversely extending from the main axle, and two external rods extending from the levers into the bores. The elastic element includes a first torque spring, a second torque spring, and an intermediate lever formed between the first and second torque springs. The first torque spring is located between and connected to the levers and adapted for biasing the buckle from the connector. The second torque spring is supported on the first lever and adapted for biasing the connector from a toolbox. The intermediate lever is placed against the first lever.
