Caster Swivel Brake Plate Structure for Load Cushioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing caster swivel restriction structures face challenges in durability due to deformation of metal plates when convex portions on the anti-swivel plate do not match with receiving portions during swivel braking, leading to increased material costs and machining time.
Innovation Solution
A caster swivel restriction structure featuring a swivel brake plate with through holes and latch pieces, supported by a synthetic resin base with biasing members like coil springs that cushion downward loads and prevent deformation by creating a gap between the swivel brake plate and the support base.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the concave receiving portion is formed as a through hole in a metal plate to strengthen concavo-convex fitting, then the fitting strength is improved, but a gap portion must be held between the metal plate and the resin support base, increasing structural complexity
Solution Approach 1:
The receiving portion is nested within the support base as a recessed cavity rather than a through hole, eliminating the need for a separate gap portion while maintaining the engagement function between the convex portion and receiving portion
2Adaptability or versatility
If multiple receiving portions are arranged on the metal plate to allow fitting of convex portions, then the adaptability is improved, but when convex portions and receiving portions deviate during swivel braking, downward load causes metal plate deformation
Solution Approach 1:
The support base is designed with enhanced rigidity and appropriate thickness to preemptively resist downward loads during swivel braking, preventing deformation before it occurs. The base structure inherently absorbs the shock of misaligned engagement without requiring additional cushioning components
Solution Approach 2:
The support base combines the metal plate with the resin support base material to create a composite structure that leverages the strength of metal and the shock-absorbing properties of resin, improving overall stability under load
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 structure effectively cushions downward loads and prevents deformation of the swivel brake plate, enhancing durability and reducing material costs by using a synthetic resin base and biasing members to absorb mismatched loads during swivel braking.
Implementation Method 1
biasing members which support the body piece aloft and are downwardly compressible are interposed between the body piece and the upper surface fitting portion
Implementation Method 2
biasing members like coil springs that cushion downward loads

AI summary
The present invention relates to an improvement in caster swivel restriction structure. The present invention is characterized in that a swivel brake plate has a body piece having a plurality of through holes arranged therein and latch pieces bent downward from the body piece, a support base has latch hole portions for fitting the latch pieces in a vertical slidable manner, a gap portion provided at a location corresponding to below the group of through holes formed in the swivel brake plate, and cushioning members or biasing members which are disposed in the gap portion and supports the swivel brake plate aloft and which is repulsively compressed when downward force is applied to the swivel brake plate.
