Flexible Guide Element for Concealed Locking Bar Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing assembly process for locking devices in doors and windows is time-consuming and error-prone due to the need for trial and error when threading locking bars into frames and connecting them with mortise locks, as these components are concealed during installation.
Innovation Solution
A mounting assembly featuring a mortise lock with at least one latch bar and a flexible guide element that allows for concealed arrangement within the door or window frame, where the locking bar is guided through a flexible guide device and connected to a suspension element, facilitating quick and reliable assembly by using a loop end that protrudes from the locking rod to connect with the mortise lock.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the locking bar is threaded into the frame and connected to the mortise lock in a concealed manner, then the aesthetic appearance is improved, but the assembly process becomes time-consuming and error-prone due to trial and error
Solution Approach 1:
The flexible guide element is pre-threaded through the locking bar before installation, with its loop end positioned in advance. This preliminary arrangement allows the locking bar to be directly guided into the correct position and connected to the mortise lock without time-consuming trial and error during the actual assembly process
Solution Approach 2:
The flexible guide element acts as an intermediary component between the locking bar and the mortise lock. It provides a physical guide path that directs the locking bar into the correct concealed position and enables reliable connection to the suspension element of the mortise lock, eliminating the need for trial and error
2Shape
If the locking bar is arranged concealed in the frame, then the aesthetic appearance is improved, but the connection to the mortise lock becomes difficult to align
Solution Approach 1:
The flexible guide element serves as a mediator that bridges the locking bar and the mortise lock. It provides a physical guide path that automatically aligns the locking bar with the suspension element of the mortise lock, making the concealed connection process straightforward and eliminating alignment difficulties
Solution Approach 2:
The flexible guide element changes the spatial parameters of the connection process by providing a three-dimensional guide path that accommodates the concealed arrangement. This flexible path allows for positional adjustments and ensures proper alignment between the locking bar and mortise lock connection devices

AI summary
This is an assembly for mounting a locking device in or on the sash of a door, window, or similar structure. The assembly comprises a mortise lock, a locking bar, and a flexible guide element associated with the locking bar. The at least one locking bar and the mortise lock can be concealed within the sash, such that the mortise lock, with its lock case, can be inserted into a recess in the sash, and the at least one concealed locking bar can be connected at its end to a connection point on the mortise lock. The locking bar protrudes with its free end through an opening in the sash.It is provided that a guide device is formed on or in the at least one locking bar, in which the associated flexible guide element can be arranged and guided at least along a section of the axial longitudinal extent of the locking bar. The end of the flexible guide element associated with the connecting device has a loop end that projects away from the locking bar. The end of the flexible guide element furthest from the loop end extends out of the guide device. The connecting device and/or the lock case has a bolt-shaped or hook-shaped attachment element into which the loop end can be hooked.
