Hook Bolt Mechanism for Sliding Door Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional deadbolt locks are incompatible with sliding doors, failing to provide security as they only prevent lateral movement of swinging doors and do not address longitudinal movement, making them unsuitable for sliding doors.
Innovation Solution
A hook bolt mechanism that includes a deadbolt and one or more hooks, which automatically move between disengaged and engaged positions as the deadbolt transitions from retracted to extended, allowing the hooks to engage a door jamb strike plate, thereby securing both sliding and swinging doors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional deadbolt lock is used, then it can prevent lateral movement of swinging doors, but it is incompatible with sliding doors that move in a longitudinal direction
Solution Approach 1:
The deadbolt is designed to automatically change its orientation based on door movement. When the door slides or swings closed, the deadbolt rotates 90 degrees to extend perpendicular to the door surface, transforming from a lateral-blocking configuration to a longitudinal-blocking configuration that secures sliding doors effectively
Solution Approach 2:
The locking mechanism is designed to serve multiple door types with a single system. The deadbolt can function in both its original lateral-blocking mode for swinging doors and its transformed longitudinal-blocking mode for sliding doors, eliminating the need for separate locking systems
2Device complexity
If a conventional deadbolt lock is used for sliding doors, then the structure remains simple, but it fails to provide security against longitudinal movement
Solution Approach 1:
The deadbolt incorporates automatic rotational movement that activates through normal door operation. The simplicity of the structure is maintained while adding dynamic functionality - the deadbolt rotates 90 degrees automatically when the door closes, transforming its blocking direction without requiring complex additional mechanisms
Solution Approach 2:
The orientation parameter of the deadbolt is changed automatically through the door's closing motion. The deadbolt transitions from extending parallel to the door surface to extending perpendicular to it, changing its functional parameter to match the security requirements of sliding doors

AI summary
A hook bolt for a latch assembly includes a hook that deploys laterally from a deadbolt when the deadbolt is moved to an extended position. When the deadbolt is actuated, the hook automatically deploys perpendicular to the deadbolt movement to an engaged position within a corresponding opening in a door jamb to secure the door.
