Drum Foot Pedal Tension Adjustment via Upper Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drum foot pedal apparatuses face difficulties in tension adjustment due to the placement of the tension adjustment mechanism, which can be cumbersome and prone to frictional wear, leading to operational challenges and increased manufacturing costs.
Innovation Solution
The drum foot pedal apparatus features a connection position adjustment section positioned above the support post, allowing for easier adjustment of the coil spring tension by relocating the connection point between the coil spring and the tension adjustment mechanism, and incorporates a positional displacement prevention mechanism to maintain stability with a reduced number of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the tension adjustment mechanism is positioned at the lower end of the coil spring as in conventional designs, then the structure is compact, but the adjustment operation becomes difficult due to interference from other components and increased frictional wear
Solution Approach 1:
The patent repositions the tension adjustment mechanism from the lower end of the coil spring to the upper end, changing the spatial dimension of adjustment. This allows the adjusting nut to be accessed from above without interference from the foot board, pivot shaft, or other lower components, making the adjustment operation easier and more accessible while reducing frictional wear issues
2Ease of manufacture
If the coil spring is engaged at its lower end by a metal rod, then the connection is simple, but frictional wear increases and noise is generated due to sliding contact
Solution Approach 1:
The patent introduces a bush as an intermediary component between the coil spring's lower end and the metal rod. This bush acts as a mediator that reduces direct metal-to-metal sliding contact, thereby minimizing frictional wear and noise generation while maintaining the simplicity of the connection structure
Solution Approach 2:
The patent replaces the direct sliding contact mechanical system with a bush-mediated system. The bush provides a low-friction interface that substitutes the high-friction metal-to-metal contact, reducing harmful effects while preserving the mechanical connection function
3Device complexity
If the tension adjustment mechanism is accessible from below, then the structure is simplified, but extra operations are required when the pedal is mounted on the drum
Solution Approach 1:
The patent inverts the conventional approach by making the tension adjustment mechanism accessible from above rather than from below. This inversion allows players to adjust tension while the drum is mounted in its normal playing position, eliminating the need to detach or tilt the drum for adjustment purposes

Implementation Method 1
a coil spring for normally urging or biasing the foot board toward an initial (non-depressed) position of the foot board (in other words, for imparting resilient self-returning force to the foot board)

AI summary
A drum foot pedal apparatus includes: a coil spring (60) imparting resilient self-retuming force to a foot board (50); a rod member or an adjusting bolt (65) supported by a support section (23) provided on a support post member (21, 22); and a tension adjustment mechanism (100) provided between the coil spring and the rod member or the adjusting bolt. The tension adjustment mechanism includes a connection position adjustment section (70, 90) that interconnects the lower end of the coil spring and the rod member or the adjusting bolt above the support post member, and that is constructed to permit adjustment of a connection position between the lower end of the coil spring and the rod member or the adjusting bolt at a position above the support section. Thus, it is possible to effectively prevent frictional wear of component parts and generation of noise and achieve an enhanced operability in the tension adjustment, with a simple construction having a minimized number of component parts.
