Archery Release Thumb Trigger Ring Sear Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing archery release devices are cumbersome to operate and require frequent re-adjustment due to loose set screws, and they do not accommodate various shooting styles effectively.
Innovation Solution
A handheld pull tension archery release with a handle, a rotatably connected bail, and a ring sear assembly that includes a thumb trigger for easy operation, adjustable spring tension, and customizable finger support configurations to ensure secure and consistent performance across different shooting styles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If adjustable set screws are used to hold the fork and catch in position, then the device can be adjusted to eliminate torque and adjust back-tension travel, but the set screws loosen during repeated firing requiring frequent re-adjustment
Solution Approach 1:
The patent replaces the mechanical set screw system with a rubber band elastic retention system. The rubber band engages with grooves in the fork and catch components, providing continuous elastic pressure that maintains adjustment positions without loosening. This substitution of mechanical fastening with elastic retention solves the problem of set screws loosening during repeated firing while preserving full adjustability of the release device.
2Ease of operation
If a traditional rope release or gripper release is used, then the bowstring can be engaged and released, but the device is cumbersome to operate and does not accommodate various shooting styles
Solution Approach 1:
The patent designs a handheld release body that can accommodate multiple finger configurations (index finger only, index and middle fingers, or all four fingers) through adjustable finger rests and a versatile handle design. The release mechanism itself remains the same but adapts to different shooting styles including traditional archery, Olympic archery, and 3D archery, making the device universally applicable across various shooting disciplines while maintaining ease of operation.
3Ease of operation
If a thumb trigger mechanism is used instead of finger-operated releases, then the release can be operated more easily with the thumb, but the mechanism becomes more complex with additional components
Solution Approach 1:
The patent merges the thumb trigger release mechanism with the traditional rope loop release mechanism into a single integrated device. The thumb trigger operates a sear that releases the same rope loop used in conventional releases, combining the ease of thumb operation with the proven reliability of rope loop mechanics. This merging approach adds minimal complexity while significantly improving ease of operation compared to traditional finger-operated releases.
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 reliable, user-friendly archery release that maintains adjustment settings securely, accommodating various shooting styles and reducing operational complexity by using a thumb trigger and adjustable spring tension, ensuring consistent performance.
Implementation Method 1
an adjustable spring within the handle which biases the ring sear toward the hold position

AI summary
A handheld pull tension archery release includes a handle containing a finger opening having an axis arranged normal to a plane containing the handle, a ring sear assembly arranged in the handle, and a bail connected with the handle for rotation about an axis parallel to the opening axis. The bail is configured to grip a bowstring. When the ring sear assembly is actuated, a ring sear arranged in the housing rotates about the finger opening axis from a hold position engaging the bail to a release position releasing the bail to free the bowstring and fire an arrow. Rotation of the ring sear is in response to pull tension on the bowstring and actuation of a thumb trigger connected with the handle.
