Treestand Platform Captive Bracket for Secure Angle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing treestand platform adjustment mechanisms often rely on moving parts that can rust, break, or become detached and lost, leading to instability and inconvenience in adjusting the platform angle.
Innovation Solution
A captive bracket mechanism with no moving parts that allows for easy angle adjustment by rocking and sliding, locking into place, preventing accidental detachment and loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If plungers or pins with springs are used for adjustment, then the platform angle can be adjusted, but the springs can rust and break, reducing reliability
Solution Approach 1:
The patent removes the spring component entirely from the adjustment mechanism. The captive bracket system uses a simple rocking and sliding motion with a locking feature that requires no elastic elements, eliminating the source of rust and breakage while maintaining adjustment functionality.
Solution Approach 2:
The invention replaces the expensive-to-maintain spring mechanism with a simple, robust captive bracket system that has no wear-prone parts. The bracket is designed to be durable and maintenance-free, effectively treating the adjustment mechanism as a permanent, non-consumable component.
2Ease of operation
If detachable adjustment mechanisms are used, then the platform can be adjusted, but the mechanisms can fall off or be lost
Solution Approach 1:
The captive bracket is nested within the treestand structure itself, with the bracket designed to fit into and be retained by the stand's framework. This nesting ensures the adjustment mechanism remains an integrated part of the treestand, preventing detachment or loss while allowing full adjustment functionality.
Solution Approach 2:
The adjustment mechanism is merged with the treestand structure through the captive bracket design. The bracket becomes an inherent part of the stand rather than a separate detachable component, combining the adjustment function with the structural integrity of the treestand to prevent loss.
3Ease of operation
If traditional plunger mechanisms are used, then adjustment is possible, but the mechanism becomes complex with moving parts
Solution Approach 1:
Instead of using a complex mechanism with multiple moving parts to achieve adjustment, the patent inverts the approach by using a simple rocking and sliding motion that relies on the geometry of the captive bracket rather than complex mechanical linkages. The adjustment emerges from the bracket's movement constraints rather than from an elaborate mechanism.
Solution Approach 2:
The patent extracts all unnecessary moving parts from the adjustment mechanism, leaving only the essential captive bracket that rocks and slides to provide adjustment. This simplification removes complexity while preserving the core adjustment functionality.

AI summary
A treestand platform adjustment mechanism adjusts the angle of a treestand platform with respect to a vertical support. The treestand's vertical support extends between a seat and a platform, the platform extending generally perpendicularly from the support, the support generally aligned with a tree. The support comprises openings extending through a tree-facing side of the support. A captive bracket substantially surrounds the support. A fixing bolt extends through the captive bracket and is received by the openings to set the position of the platform with respect to the support.
