Building Locking Device Motorized Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional window and door locking devices, especially large and heavy ones, require significant manual force to actuate and often feature complex mechanisms with comfort axers that complicate the structure and make tilting processes cumbersome.
Innovation Solution
A motorized auxiliary drive system that supports the actuation of the locking device, allowing for smooth and effortless manual operation by engaging with the actuating element and eliminating the need for comfort axers, which provides positive control for tilting movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional manual locking devices are used for large and heavy window or door sashes, then the locking function is achieved, but significant manual force is required and the structure becomes complex with comfort axers
Solution Approach 1:
The patent replaces the traditional mechanical comfort axer system with an electromechanical actuator that directly drives the locking element. This substitution eliminates the need for complex mechanical linkages and comfort axers, reducing overall device complexity while providing motorized assistance to reduce manual actuation force.
Solution Approach 2:
The actuator serves multiple functions: it provides motorized assistance for manual operation, enables fully automated operation, and integrates the previously separate comfort axer function directly into the locking mechanism. This multi-functionality reduces the number of separate components needed.
2Ease of operation
If comfort axers are added to enable positively controlled tilting, then tilting control is improved, but the structure of the locking device and window becomes more complex
Solution Approach 1:
The patent merges the comfort axer function with the locking element itself. The locking element is designed to perform both the locking function and the comfort axer function for positively controlled tilting. This integration eliminates the need for separate comfort axer components and their associated linkages.
Solution Approach 2:
The locking element is designed as a multi-functional component that simultaneously provides locking engagement and serves as the control mechanism for positively controlled tilting. This universal design eliminates the need for additional dedicated comfort axer components.
3Reliability
If multiple locking pins or engagement elements are used to secure heavy sashes, then locking reliability is improved, but the number of mechanical components increases and actuation becomes more difficult
Solution Approach 1:
The patent replaces the system of multiple mechanically interconnected locking pins with a single actuator-driven locking element. The actuator provides the necessary force to move the locking element, which then engages multiple locking positions or pins simultaneously, reducing actuation difficulty while maintaining reliability.
Solution Approach 2:
The actuator serves as an intermediary mechanism that translates a single user input into the coordinated movement of multiple locking elements. This intermediary provides mechanical advantage and coordination, making it easier to actuate multiple locking points simultaneously.

AI summary
The closing device has a pivoting wing (13) that is disposed on one hinge (11) at a hinge side of the closing device, where the hinge is pivotally mounted on a frame (10). A locking device locks the pivoting wing in a locked position with the frame, where the pivoting wing is movable in an unlocked position, in which the pivot wing is pivotable around a pivot axis (L1) relative to the frame. A drive device is adapted to adjust the locking device acting on the one locking element on the hinge side. The locking element is made of a lever pivotable by an articulation point. An independent claim is included for a method for operating a closing device for a building opening.
