Drum Foot Pedal Spike Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drum foot pedal apparatuses experience positional displacement due to repeated footboard depression, and existing spike members fail to effectively prevent lateral rotational displacement, especially with double-pedal structures, and are difficult to adjust during performance.
Innovation Solution
The drum foot pedal apparatus features spike members on the heel or base member that are adjustable from above, allowing for easy adjustment and effective prevention of positional displacement, with the spike members being retractable to avoid interference during performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spike members are attached to the frame section to prevent positional displacement, then the foot pedal apparatus is retained on the installing surface, but the spike members cannot provide sufficient lateral-rotational-displacement preventing force
Solution Approach 1:
The invention transitions from a single-spike configuration to a multi-spike arrangement distributed across multiple dimensions (front frame section, heel section, and side surfaces). This spatial distribution creates a stabilizing geometry that resists lateral rotational forces through the combined effect of multiple projection points, effectively converting a one-dimensional stabilization approach into a three-dimensional stabilizing structure.
Solution Approach 2:
The invention combines multiple spike members into an integrated stabilization system where spikes are mounted on both the front frame section and the heel section simultaneously. This merging of stabilization functions at different locations creates a unified anti-rotation mechanism that leverages the geometric relationship between the front and heel sections to generate sufficient lateral-rotational-displacement preventing force.
2Ease of operation
If the spike member is made pivotable between retracted and projected positions, then the spike member can be adjusted, but operations for projecting and retracting require a tool and cannot be performed easily from above the upper surface
Solution Approach 1:
The spike member incorporates a self-adjusting mechanism where the operator's foot directly actuates the projection and retraction of the spike through a simple lever action. The foot-operated mechanism eliminates the need for external tools or complex adjustment devices, allowing the operator to easily adjust the spike position from above the upper surface by simply applying foot pressure in the desired direction.
3Reliability
If spike members are provided on the frame section, then positional displacement is prevented, but the left foot pedal cannot be retained appropriately in a double-pedal structure
Solution Approach 1:
The invention segments the stabilization function by providing separate spike members on the front frame section and additional spike members on the heel section. This segmentation allows each spike group to independently contribute to stabilizing different parts of the double-pedal structure, with the heel section spikes specifically supporting the left foot pedal and the front frame spikes supporting the overall apparatus, thereby appropriately retaining both foot pedals.

AI summary
A drum foot pedal apparatus is provided which can effectively prevent, by a spike member, positional displacement of the apparatus from occurring due to depression of a foot board and permits adjustment of a projected amount of the spike member with a simple construction. The apparatus includes: a base member fixed at one end to a frame section and fixed at the other end to a heel member, thereby interconnecting the frame section and the heel member; and a spike member provided on the base member in such a manner as to be projectable downward beyond the lower surface of the base member. The spike member is disposed at a position where it does not positionally overlap the foot board, and the spike member is constructed so that the projected amount of the spike member is adjustable by an operation from above the upper surface of the foot board.
