Adjustable Cylinder Lock Protection via Movable Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lock protections for cylinder locks lack flexibility to adapt to different lock/door constructions while maintaining high security and ease of use.
Innovation Solution
A lock protection system comprising a first part with a threaded cylindrical surface and a second, ring-shaped part that can be moved along it, locked relative to the first part using blocking means like pins or balls, allowing for adjustable positioning and secure locking, with the ability to accommodate various lock cylinder designs and door configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the lock protection is manufactured as a single piece, then the manufacturing process is simple, but the adaptability to different lock/door constructions is poor
Solution Approach 1:
The lock protection is divided into multiple parts: a first part with a threaded cylindrical surface and a second ring-shaped part that can be moved along it. This segmentation allows the second part to be positioned at different locations to accommodate various lock cylinder protrusion distances, thereby achieving adaptability to different constructions while keeping each individual part simple to manufacture.
2Adaptability or versatility
If the lock protection is made flexible with adjustable parts, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The second ring-shaped part is designed to be movable along the threaded cylindrical surface of the first part, allowing dynamic adjustment of the lock protection configuration. This movability enables adaptation to different lock/door constructions without requiring completely different designs, as the same basic structure can be adjusted to fit various scenarios.
Solution Approach 2:
The second ring-shaped part is positioned around the first part, with the second part essentially nested on the cylindrical outer surface of the first part. This nesting arrangement allows for compact design while maintaining adjustability, as the movable second part can be positioned at different locations along the first part without significantly increasing overall device complexity.
3Reliability
If blocking means are added to lock the parts relative to each other, then the security improves, but the device complexity increases
Solution Approach 1:
The blocking means are pre-positioned in holes formed in the first part, and corresponding recesses are pre-formed in the second part. This preliminary arrangement of blocking elements allows for secure locking when the parts are assembled, while avoiding the need for complex locking mechanisms during operation. The blocking means are already in place to engage when needed.

AI summary
The invention concerns a lock protection for a cylinder lock for a door. The lock protection has a first part (28) with a substantially cylindrical outer surface (36). The first part (28) is adapted to receive a lock cylinder (20, 22). The lock protection also has a second, substantially ring-shaped, part (46) with a substantially round second hole (48) which is adapted to said substantially cylindrical outer surface (36) of the first part (28). The second part (46) can be moved to different positions along the substantially cylindrical outer surface (36) and can be locked in a selected position relative to the first part (28). The lock protection enables an adaptation to different lock/door constructions. The invention also concerns a use of the lock protection.
