Overview
Filed on August 14, 2019 and granted on February 23, 2021, this patented guard plate embodies a practical mechanical solution for protecting vehicle fluid portals. Inventors based in Plantersville, TX worked with Creative Alloy Products Co. to develop a robust plate body that mounts with lower bolts and uses engineered rotational origins and radii so the plate pivots smoothly to cover or expose a protected surface. The design’s curved top edge and purpose-built upper indentions guide fastener movement and avoid interference, while integrated fastener catches and slotted openings balance security with serviceability. The result is a physically simple yet technically precise accessory that discourages misfueling (for example, diesel into DEF ports) while allowing straightforward maintenance access.
This patent highlights careful claim drafting around rotational geometry, fastener alignment, and user interaction constraints—demonstrating the firm’s technical depth in translating practical vehicle-access problems into enforceable intellectual property.
Key Features
- Curved top edge aligned to a defined rotational radius to prevent fastener snagging
- Upper indentions and half‑circular fastener catches for selective retention
- Lower bolt hole serving as a rotational origin for controlled pivoting
- Slotted openings enabling tool‑assisted removal while deterring accidental access
By combining mechanical precision with user‑experience considerations, the guard plate reduces costly contamination events and supports safer vehicle maintenance practices across agricultural and off‑road equipment sectors.
