Cycle Accessory Mount With Angular Locking for Rack-Free Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cycle accessory mounting systems are limited by the need for bulky and heavy wire carrier racks, which are not compatible with all cycle types, especially those without eyelets or with carbon fiber frames, and traditional panniers can interfere with suspension and disc brake setups, while frame bags are restrictive in load size and require customization.
Innovation Solution
A system comprising a mounting part with an axially extending member and transversely projecting lugs, a receiving part with a recess and lip for angular adjustment, and a locking member for secure attachment to various cycle components, allowing for easy installation and adjustment of accessories like bags and baskets without the need for traditional racks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional wire carrier racks are used to mount panniers, then load-carrying capacity is improved, but weight and bulk increase significantly
Solution Approach 1:
The patent extracts the essential mounting function from the traditional wire carrier rack system, eliminating the bulky rack structure while retaining the ability to securely mount panniers. The mounting system uses direct attachment points on the cycle frame with simplified clamping mechanisms, removing unnecessary structural elements that added weight and bulk.
Solution Approach 2:
The invention applies local quality by creating specialized mounting points at specific locations on the cycle frame (front fork, rear stay, seat tube) with tailored clamping mechanisms for each location. This allows the mounting system to be lightweight overall while providing sufficient load-carrying capacity at each specific mounting point.
2Adaptability or versatility
If traditional wire carrier racks are used, then panniers can be mounted, but compatibility with all cycle types is reduced
Solution Approach 1:
The patent implements universality by designing a multi-functional mounting system that can attach to various cycle frame types (steel, aluminum, carbon fiber) and different locations (front fork, rear stay, seat tube). The clamping mechanisms are designed to accommodate different frame geometries and materials, making the system compatible with modern cycles that lack traditional eyelets while maintaining relatively simple construction.
3Quantity of substance
If traditional panniers are used with carrier racks, then load capacity is improved, but interference with suspension and disc brakes occurs
Solution Approach 1:
The invention addresses interference issues by carefully positioning mounting points and designing clamping mechanisms that clear suspension components and disc brake rotors. Each mounting location (front fork, rear stay, seat tube) is specifically designed to avoid interference with local components while maintaining load-carrying capacity.
4Weight of moving object
If frame bags are used for off-road touring, then weight and bulk are reduced, but load size is limited
Solution Approach 1:
The patent merges the advantages of frame bags (lightweight, low profile) with the capacity of panniers by using the cycle frame itself as the mounting structure. Multiple mounting points distributed across the frame allow attachment of multiple bags, effectively combining frame bag weight efficiency with pannier-style load capacity.

AI summary
A system for mounting an accessory to a cycle has a mounting part (400), a receiving part (500), and a locking member (508). The mounting part (400) has an axially extending member (402) and at least one transversely projecting lug (406). The receiving part (500) has a recess for receiving the member (402) and the lug(s) (406) when the receiving part (500) is in a receiving/releasing position, and at least one lip (506) for engaging with the lug(s) (406) to retain the mounting part (400) when the receiving part (500) is angularly moved relative to the mounting part (400). The locking member (508) is operable between the mounting part (400) and the receiving part (500), and is moveable between an unlocked position and a securing position to selectively retain the receiving part (500) in a plurality of angularly offset locked positions relative to the mounting part (400).
