Kickstand Telescopic Leg Button Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional telescopic kickstands require special tools and are not always stable, as the locking mechanism can loosen under stress, leading to potential functional failure and safety risks.
Innovation Solution
A kickstand with a button-based locking system using elastic means to secure the telescopic leg, allowing intuitive length adjustment without tools and ensuring stability through a self-centering button and helical spring mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw-based locking system is used to secure the telescopic leg, then the kickstand can be locked in position, but the adjustment requires special tools and takes a long time
Solution Approach 1:
The patent replaces the traditional screw-based mechanical locking system with a spring-loaded button mechanism. The button, when pressed, releases the locking engagement between the telescopic elements, allowing quick adjustment without tools. The spring automatically maintains the button in the locked position, providing reliable securing while enabling rapid adjustment by simply pressing the button.
Solution Approach 2:
The spring-loaded button mechanism is designed to be self-maintaining. The spring automatically keeps the button engaged in the locking position without requiring additional fastening operations. When adjustment is needed, the user simply presses the button to disengage and reposition the telescopic elements, and the spring automatically re-engages the locking mechanism, eliminating the need for manual screw tightening.
2Reliability
If a screw-based locking system is used, then the kickstand can be secured, but the screw may loosen under constant stress
Solution Approach 1:
The patent replaces the screw-based mechanical system with a spring-loaded button system. The spring continuously applies force to keep the button engaged, creating a positive locking mechanism that resists loosening. This eliminates the problem of screws working loose under vibration and stress, as the spring mechanism naturally compensates for any displacement and maintains constant engagement pressure.
3Reliability
If a screw-based locking system is used, then the telescopic elements can be secured, but the user must adopt uncomfortable positions to operate it
Solution Approach 1:
The patent replaces the screw-based system with a button mechanism that can be operated with a simple finger press. This eliminates the need for the user to crouch or bend into uncomfortable positions to manipulate a screw with a hex key or screwdriver. The button is positioned and sized for easy access and operation in various riding positions, significantly improving user comfort while maintaining secure locking.
4Ease of operation
If a button with elastic means is used for locking, then quick adjustment without tools is enabled, but the mechanism must ensure stability under stress
Solution Approach 1:
The spring-loaded button mechanism is designed to be self-maintaining under stress. The spring continuously applies force to keep the button engaged in the locking position, automatically compensating for any vibrations or stresses applied to the kickstand. This self-service mechanism ensures that the locking remains stable without requiring additional user intervention or complex adjustment procedures.

AI summary
A kickstand with adjustable length (10), which comprises a fixing bracket (11) to which a telescopic leg (12) with a resting foot (13) is articulated; the telescopic leg (12) comprises a first element (14) articulated to the bracket (11) and a second element (15), which can be extracted telescopically with respect to the first element (14) and is provided with the resting foot (13); reversible means are provided for locking the position of the second element (15) with respect to the first element (14). The reversible locking means comprise: - a button (16), which is accommodated in a corresponding seat (17) defined in the inner element of the first element (14) and the second element (15) and open toward the outer element of said first element (14) and second element (15), with elastic means for pushing the button (16) toward the outside of the seat (17), - a series of through holes (18, 19, 20, 21, 22, 23) which are defined on the outer element of the first element (14) or second element (15) and are shaped to be crossed by a protruding end (24) of the button (16) in a mutual locking configuration between the first and second elements.
