Bicycle Lock Bolt Latch Mechanism for Wheel Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle locks fail to provide a robust and user-friendly mechanism for securely blocking a bicycle wheel, particularly in preventing rotational movement, and often require complex operations or additional components for effective locking.
Innovation Solution
A bicycle lock system featuring a tube assembly with a bolt, channel, and latch mechanism that allows for manual or electromechanical operation, where the bolt is inserted into receiving means at the wheel, such as a disk with tapered recesses, to block rotation, and includes actuation and latch mechanisms for secure locking and unlocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional ring lock or cable lock is used to block the wheel, then the bicycle can be locked, but the locking mechanism is complex and requires additional components
Solution Approach 1:
The patent combines the bolt, latch, and receiving means into an integrated locking system where the bolt is received within the latch structure. The latch serves dual functions as both a locking mechanism and a housing for the bolt, eliminating the need for separate ring locks or cable locks and reducing overall device complexity while maintaining security.
Solution Approach 2:
The latch structure serves multiple functions: it houses the bolt, provides the blocking action against the wheel, and includes receiving means for the bolt. This multi-functional design replaces traditional separate locking components with a single integrated assembly that achieves the same security objectives.
2Reliability
If a robust locking mechanism is implemented to prevent wheel rotation, then security is improved, but the operation becomes more difficult and less user-friendly
Solution Approach 1:
The bolt is pre-positioned within the latch structure and aligned with the receiving means before engagement is required. When the user activates the locking mechanism, the bolt is already in position to engage with the wheel's brake disc or hub, eliminating the need for complex manual manipulation during the locking operation.
Solution Approach 2:
The latch structure automatically guides and positions the bolt during engagement with the receiving means on the wheel. The mechanical design ensures proper alignment and engagement through the structure itself, reducing the operational effort required from the user while maintaining secure locking.
3Ease of operation
If the bolt is manually pushed into the blocking state by manpower, then the locking is direct and simple, but sufficient force must be applied to overcome resistance
Solution Approach 1:
The latch structure incorporates dynamic elements that allow the bolt to move smoothly during engagement. The receiving means on the wheel are designed to guide the bolt's motion, reducing friction and resistance during the pushing operation. This dynamic design enables users to engage the lock with minimal force while ensuring secure blocking.
4Strength
If the receiving means are formed by a fixed part of the wheel such as an opening in a brake disc, then the mounting is firm and robust, but the receiving means must be precisely positioned
Solution Approach 1:
The receiving means are implemented as localized features (openings or recesses) in the wheel's brake disc or hub at specific positions where the bolt needs to engage. This localized approach allows the receiving means to be precisely positioned only where required for locking functionality, without requiring high precision across the entire wheel structure. The firm mounting is achieved by integrating these localized features directly into the wheel's existing structure.

AI summary
The present invention relates to a bicycle lock for blocking of a wheel of a bicycle in a locked state. The bicycle includes a tube assembly including a frame with mutually fixed tube elements and movable tube elements, such as a front stay. The bicycle includes a housing, a bolt for providing a blocking action in a blocking state with which the wheel is blockable, a channel for arranging therein of the bolt, and a latch for, in a latching state of the lock, keeping the latest in the blocking state. The latch in the blocking state is in cooperation with receiving means defining a state of cooperation in which the bolt and the receiving means block the wheel of the bicycle.
