Portable Hunting Platform with Winch-Actuated Pivoting Legs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable deer stands are cumbersome and difficult to move between transport and use positions, often requiring partial assembly and lacking a simple mechanism for converting between horizontal and vertical leg positions.
Innovation Solution
A portable elevated platform assembly with a trailer, pivotally attached legs, and a winch system that uses cable systems to easily transition between lowered transport and raised use positions, along with a ladder for access, allowing for quick and efficient movement and setup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If portable deer stands are designed to be moved between transport and use positions, then mobility is improved, but the structure becomes cumbersome and difficult to move
Solution Approach 1:
The patent applies dynamics by making the support legs movable between vertical and horizontal positions through pivotal attachment points. The legs can dynamically transition from a vertical configuration during use to a horizontal configuration during transport, allowing the stand to adapt its structure based on operational requirements rather than being fixed in one position
Solution Approach 2:
The patent implements nesting by allowing the support legs to be positioned horizontally along the trailer frame during transport, effectively nesting the leg structure within the trailer's footprint. This nested configuration minimizes the overall size and makes the stand easier to tow and store when not in use
2Adaptability or versatility
If portable deer stands require conversion between transport and use positions, then adaptability is improved, but the process becomes time-consuming and complex
Solution Approach 1:
The patent applies preliminary action by pre-configuring the support legs with pivotal attachment points and cable system connections that are ready for immediate deployment. The legs are designed to naturally follow the lifting motion of the platform, eliminating the need for manual assembly steps or complex conversion procedures during field deployment
Solution Approach 2:
The patent implements self-service through the cable system that automatically raises and lowers the support legs as the platform is lifted or lowered. The cables are connected to the legs through linkages that convert the vertical motion of the platform into the appropriate leg movement, allowing the structure to self-adjust without requiring manual intervention for each conversion action
3Stability of the object's composition
If the platform is elevated for use, then the viewing position is improved, but the structure becomes unstable during movement
Solution Approach 1:
The patent applies dynamics by designing the support legs to be vertically positioned and locked during platform use, providing stable elevation. During transport, the same legs can be pivoted to a horizontal position along the trailer frame, transforming the structure from a stable elevated platform to a compact transport configuration. The pivotal joints allow this dynamic reconfiguration while maintaining structural integrity in both states
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 a lightweight, economical, and safe platform that can be easily moved and set up, providing a stable elevated position for hunters and photographers, improving usability and convenience.
Implementation Method 1
A winch is mounted to the frame. A first cable system extends between the winch and the frame. A second cable system extends between the front and back legs. A connector interconnects the first and second cable systems, whereby actuation of the winch moves the legs between raised and lowered positions via the cable systems.
Implementation Method 2
A first cable system extends between the winch and the frame. A second cable system extends between the front and back legs.

AI summary
A portable lookout platform is provided with legs which can be moved between raised and lowered positions via a cable and winch system. Pulleys and rollers provide for controlled movement of the legs. A platform is mounted on top of the legs to support a person. The ladder provides access for a person to the platform when the legs are raised. The legs, platform and ladder are mounted on a trailer for transportation.
