Articulated Sliding Gate Wheel Mount for Anti-Derailment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-derailment systems for articulated sliding gates require a tubular upright to house a piston element, helical spring, and abutment, making installation labor-intensive and expensive, and are limited to gates with suitable dimensions, and cannot be retrofitted to existing gates without modifications.
Innovation Solution
A sliding gate system with a wheel-holder element connected to a bearing body via a hinging means and elastic push means, allowing wheels to adapt to guide deformations, ensuring continuous contact with the guide and preventing derailment without needing a tubular upright.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a piston element with helical spring and abutment is installed inside a tubular upright to prevent derailment, then the anti-derailment function is improved, but the device complexity and installation cost increase significantly
Solution Approach 1:
The invention extracts the wheel from the tubular upright structure and positions it externally on the lower stretch of the upright. The wheel is mounted on a pivot pin that allows it to rotate freely, eliminating the need for complex internal housing while maintaining the anti-derailment function through the wheel's external contact with the guide rail
Solution Approach 2:
Instead of housing the wheel inside the tubular upright as in conventional designs, the invention inverts the arrangement by mounting the wheel externally on the lower stretch of the upright. This inversion simplifies the structure by removing the need for internal piston and spring mechanisms while achieving the same safety function
2Reliability
If a tubular upright is required to house the piston and spring mechanism, then the anti-derailment system functions properly, but the ease of manufacture and installation deteriorates due to labor-intensive work
Solution Approach 1:
The wheel is extracted from the tubular upright interior and mounted externally, eliminating the need for complex assembly operations inside the upright. This allows for much simpler installation that does not require specialized labor or time-consuming assembly procedures
Solution Approach 2:
The conventional approach of installing components inside the tubular upright is inverted by mounting the wheel externally. This inversion transforms a complex, labor-intensive installation process into a simple operation that can be performed quickly and easily
3Reliability
If the anti-derailment system uses a piston element inside the upright, then the wheel can be pushed down to maintain contact with the rail, but the ease of repair deteriorates as wheels cannot be easily removed or replaced
Solution Approach 1:
The wheel is extracted from the enclosed tubular upright structure and mounted externally on the lower stretch. This external mounting allows the wheel to be easily accessed, removed, and replaced without requiring disassembly of the upright or specialized tools, significantly improving maintenance ease
Solution Approach 2:
Instead of enclosing the wheel inside the upright where it is difficult to access for repair, the invention inverts the arrangement by mounting the wheel externally. This makes the wheel easily accessible for maintenance operations while still providing the necessary downward force to maintain rail contact
4Reliability
If the anti-derailment system is designed with specific dimensional requirements for the upright, then the piston and spring can be housed properly, but the adaptability to different gate configurations deteriorates
Solution Approach 1:
The wheel is extracted from the tubular upright interior, eliminating the need for specific dimensional requirements for housing the mechanism. This allows the system to be adapted to various upright sizes and gate configurations without being constrained by internal space requirements
Solution Approach 2:
The external wheel mounting design creates a universal solution that can be applied to different gate types and configurations. The wheel assembly can be mounted on various upright dimensions and gate structures, making the anti-derailment system highly adaptable and versatile across different applications

The push means of a wheel-holder element (15) comprise: - a bearing body (16) constrained to a lower portion of a section (11a, 11b); - hinging means (17) for the rotatable constraint of the wheel-holder element (15) with respect to the bearing body (16) around an axis of rotation (X2) parallel to the axis of rotation (X1) of the wheel (12, 13); - elastic push means (18) configured to push the wheel-holder element (15) to rotate around the axis of rotation (X2) so that the rest and sliding wheel (12, 13) moves away from the bearing body (16). The bearing body (16) is constrained to the lower portion of a section (11a, 11 b) with rotatable constraint means (80) with vertical axis.
