Pole Vault Swing-Up Rack with Push Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pole vault training devices require complex movements and positions, making training less efficient and less effective in simulating the actual mechanics of the pole vault action.
Innovation Solution
A pole vault swing-up rack with a rectangular frame, vertical uprights, upper and lower crossbars, hooks, and a push bracket, along with foam pads for comfort, allows athletes to practice the vertical raise by kicking and pushing, simplifying the training mechanics and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If prior art athletic training devices simulate the total movement of pole vault with multiple movements and positions, then the training more closely simulates actual pole vault action, but the training becomes more complex and less efficient
Solution Approach 1:
The training device segments the pole vault action into distinct phases by providing multiple support positions (first support position for initial swing, second support position for upward motion). This allows the complex movement to be broken down into manageable segments that can be practiced independently, reducing training complexity while maintaining simulation accuracy.
Solution Approach 2:
The device introduces intermediate support structures (uprights, crossbars, and support positions) that act as mediators between the athlete and the ground. These intermediaries provide controlled assistance at specific points in the movement, making the training less complex by offering structured guidance through the motion sequence.
2Reliability
If prior art devices require maintaining shoulders forward of vertical line during training, then the training simulates actual pole vault posture, but the training becomes more difficult and less efficient
Solution Approach 1:
The device dynamically adjusts the required posture through its multiple support positions. The first support position allows shoulders to be forward of the vertical line during the swing phase, while the second support position naturally guides the athlete into a more upright posture during the upward motion phase. This dynamic adaptation maintains posture accuracy while improving training ease.
Solution Approach 2:
The device provides beforehand cushioning by offering controlled support at intermediate positions during the movement sequence. The support structures are positioned to provide assistance before the athlete reaches difficult portions of the motion, cushioning the training difficulty while maintaining proper posture requirements.

AI summary
A pole vault swing-up rack includes a frame body with upper hooks and a lower push bracket. The rack is designed to hang vertically from a horizontal bar—as a pull-up bar—by the hooks. An athlete hanging from the pull-up bar in an upright vertical position may kick his/her legs and torso up to an inverted vertical position to simulate movement of a pole vault. The athlete's shoulders rest against vertical uprights of the rack to maintain the athlete's shoulders and body in front of a vertical plane as in a pole vault movement. A trainer can use the lower push bracket to assist the athlete in the kicking motion. The parts of the rack that come into contact with the athlete may be covered in foam padding and a rubber coating.
