Multi-Point Pivot Door Lock with Universal Cylinder Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-point door locks for pivoting doors are not compatible with conventional deadbolt lock cylinders and latch hardware, limiting their use and security, as they require specific handles or actuators and cannot accommodate conventional spring latch and deadbolt systems effectively.
Innovation Solution
A door lock system featuring a drive bar, locking member, and bar slide with a transmission mechanism that allows vertical movement of the drive bar and linear movement of the bar slide, enabling the locking member to extend and retract, and is adaptable to various lock cylinder and deadbolt configurations, including those from different manufacturers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-point locks use specific handles or actuators, then the locking mechanism can be actuated properly, but the lock cannot be used with conventional latch and deadbolt systems
Solution Approach 1:
The lock mechanism is designed with a universal interface that can accept multiple types of actuators including conventional deadbolt cylinders, latch handles, and specialized multi-point lock actuators. The drive bar and transmission mechanism are configured to work with different actuator types, allowing one lock body to serve multiple functions and compatibility requirements.
Solution Approach 2:
The transmission mechanism includes movable components such as the drive bar that can change its operational characteristics based on the actuator type being used. The system can dynamically adjust its mechanical transmission path to accommodate different actuator geometries and motion patterns, enabling reliable operation across various actuator configurations.
2Reliability
If multi-point locks are configured for specific actuators, then the locking elements can be extended and retracted reliably, but the lock cannot accommodate various manufacturers' lock cylinders
Solution Approach 1:
The drive bar assembly is designed with a universal mounting interface that can accommodate lock cylinders from different manufacturers. The transmission mechanism uses standardized connection points and adjustable components that can be configured to work with various cylinder geometries and actuator types while maintaining reliable locking element actuation.
3Ease of operation
If conventional spring latch and deadbolt systems are used with pivoting doors, then the door can be secured, but only a moderate level of security is provided
Solution Approach 1:
The invention merges the conventional deadbolt or latch actuator with a multi-point locking mechanism that distributes locking points across multiple locations on the door edge. This combination provides both the ease of operation of conventional systems and the enhanced security of multi-point locking by engaging multiple locking elements simultaneously.
Solution Approach 2:
The locking mechanism transitions from a single-point locking approach to a multi-point distribution along the door edge. By adding the dimension of multiple locking points spaced apart along the door, the system provides enhanced security while maintaining the operational simplicity of conventional actuators through the universal interface design.

AI summary
A high security locking system can be used in a conventional pivot door adapted for use with a latch and deadbolt lock combination. The high security system can be a multi-point lock, received in a recess formed in a locking edge side of a door stile, cooperating with a linkage or other mechanism in a conventional deadbolt/location. The lock can be actuated with a keyed cylinder and thumb turn combination.
