Torque Pull-Up Bar Assembly with Selective Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pull-up bars cause hand blisters and skin tearing due to their static nature, require frequent re-gripping, and are impractical for high-repetition exercises, especially in competitions, and freewheeling bars pose safety risks and are not suitable for all maneuvers.
Innovation Solution
A torque pull-up bar assembly that provides selective and limited rotation with 'spring back' to a neutral position, offering adjustable rotation resistance from static to freewheeling, reducing hand slippage and the need for hand grips, and enhancing grip duration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a static pull-up bar is used, then the bar provides stable support structure, but the hand rubs against the bar causing blisters and skin tearing
Solution Approach 1:
The pull-up bar is designed to rotate dynamically during use, allowing the bar to move with the user's hand rather than remaining static. This dynamic rotation prevents the hand from rubbing against the same spot on the bar, thereby reducing friction and preventing blisters while maintaining structural stability through the mounting assembly.
2Stability of the object's composition
If a static pull-up bar is used, then the bar maintains fixed position, but the athlete must frequently re-grip the bar during repetitions
Solution Approach 1:
The bar rotates dynamically during pull-up movements, keeping the hand in contact with the bar surface throughout the repetition. This eliminates the need to re-grip the bar, allowing for continuous repetitions without disruption to rhythm or momentum, thereby improving productivity while maintaining position stability.
3Object-affected harmful factors
If a freewheeling pull-up bar is used, then the bar rotates freely preventing hand rubbing, but the bar is difficult to control and safe for all maneuvers
Solution Approach 1:
The bar provides controlled dynamic rotation rather than complete freedom of movement. The rotation is sufficient to prevent hand rubbing and reduce friction, but limited enough to maintain grip control and ensure safety during various maneuvers, thereby balancing ease of operation with harm reduction.
4Object-affected harmful factors
If hand grips are used, then hand protection is provided, but the equipment adds complexity and cost
Solution Approach 1:
The invention extracts the protective function from separate hand grips and integrates it directly into the pull-up bar structure. By making the bar itself rotate dynamically, the bar provides the protective function that would otherwise require separate hand protection equipment, thereby eliminating the need for additional complex gear while maintaining hand protection.

Function Achieved in This Case
The torque pull-up bar assembly reduces hand blisters, minimizes re-gripping, and allows for continuous exercise without disrupting rhythm, while being cost-effective, durable, and adaptable for various training needs.
Implementation Method 1
a torque assembly (16) configured to provide selective and limited rotation and 'spring back' to a natural or neutral position of the pull-up bar (14) during the natural movement of an individual completes an exercise
Data Source
AI summary
The disclosure provided herein is directed to a torque pull-up bar having a torque assembly positioned over a pull-up bar that is configured to selectively limit the rotation of a pull-up bar between a static position and freewheeling. In a strong resistance configuration and a weak configuration, the pull-up bar is capable of a limited rotation due to a resistance member that is biased to return to a natural state. Through selective engagement of the resistance member with the pull-up bar, the degree of rotation is modified.
