Snowboard Binding Highback Lock Lever Stopper Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional snowboard bindings with tether systems are cumbersome and inconsistent, leading to accidents when the snowboard slides due to lack of a functional stopper mechanism during boot mounting/dismounting, and the existing stopper function does not automatically engage when boots are removed.
Innovation Solution
A snowboard binding with a highback that automatically rotates rearward and locks into place using a connecting cord and urging body, allowing the lock lever to contact the snow surface, thereby preventing sliding when boots are removed, eliminating the need for a separate tether and enhancing safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tether is provided to prevent snowboard sliding, then safety is improved, but the device complexity and ease of operation deteriorate due to separate mounting/dismounting operations and poor appearance
Solution Approach 1:
The patent combines the tether function with the existing lock lever mechanism. The lock lever serves dual purposes: locking the highback during riding and acting as a stopper by extending to contact the snow surface when the highback is tilted rearward. This integration eliminates the need for a separate tether device, reducing overall system complexity while maintaining safety functionality.
Solution Approach 2:
The lock lever is designed with multi-functionality, serving both as a locking mechanism for the highback and as a stopper device that contacts the snow surface to prevent sliding. This universal component performs multiple safety-related functions, eliminating the need for separate dedicated tether or stopper devices.
2Reliability
If a tether is provided to prevent snowboard sliding, then safety is improved, but ease of operation deteriorates due to separate mounting/dismounting operations
Solution Approach 1:
The patent merges the stopper function into the boot removal operation. When the rider tilts the highback rearward to remove boots, the lock lever automatically extends and contacts the snow surface, providing stopper functionality during the same operation. This eliminates the need for separate tether attachment/detachment steps, improving ease of operation while maintaining safety.
Solution Approach 2:
The system provides self-service functionality where the stopper action occurs automatically during the boot removal process. The lock lever self-extends and contacts the snow surface without requiring additional rider input, making the safety function activate itself during the necessary boot removal operation.
3Reliability
If the stopper function automatically engages when boots are removed, then safety is improved, but the device complexity increases due to additional mechanisms
Solution Approach 1:
The lock lever is designed as a dynamic component that changes position based on highback orientation. When the highback is in the riding position, the lock lever is retracted and locked. When the highback is tilted rearward for boot removal, the lock lever automatically extends under its own weight or spring force to contact the snow surface. This dynamic behavior provides automatic stopper engagement without requiring complex control systems.
Solution Approach 2:
The automatic stopper engagement is achieved through self-service mechanisms where the lock lever's position is determined by the highback orientation and gravity. The system automatically transitions from a retracted locked state to an extended stopper state during boot removal, eliminating the need for additional actuators or control mechanisms.
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 solution provides a practical and safe snowboard binding that prevents accidents by automatically engaging the stopper function when boots are removed, ensuring the snowboard does not slide, and simplifies the boot mounting/dismounting process without requiring a tether, thus enhancing user experience and safety.
Implementation Method 1
an urging body 9 for rotatably urging the highback 4 rearward is provided to the highback 4
Implementation Method 2
when the highback 4 arrives at the rearward-rotation-limit position or near the rearward-rotation-limit position, the connecting cord 8 is tensioned, the orientation at which the lock lever 7 projects from the highback 4 rear surface section is maintained

AI summary
Provided is a snowboard binding in which a stopper function operates when a boot is removed and the stopper function is released when a boot is mounted, and a stopper device for a snowboard binding. The snowboard binding is provided with an urging body for rotatably urging a highback rearward, and configured so that when a lock lever of a lock mechanism is placed in an unlocked state by the rotational urging of the urging body, the highback automatically rotates rearward, and configured so that when the highback arrives at the rearward-rotation-limit position or near the rearward-rotation-limit position, a connecting cord of the lock mechanism is tensioned, the orientation in which the lock lever projects from the highback rear surface section is maintained, and the lock lever in this projecting orientation makes contact with the snow surface below a snowboard to bring about a slide-preventing effect.
