Panic Lock Key-Operated Slide Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing panic lock designs are complex and costly due to the need for numerous components to manage different operating states, particularly in ensuring reliable locking while allowing emergency escape from the inside and secure operation from the outside.
Innovation Solution
A key-operated slidable locking device controls the connecting rod slide and nut coupling, eliminating the need for separate components by using a conically tapering latching element and a claw adjustable to the nut axis, with a slide associated with the latching element's longitudinal edge, allowing automatic locking and unlocking via a single key-operated mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate components are used to manage different operating states (locking, emergency escape, external operation), then the lock can achieve reliable locking and emergency escape functionality, but the device complexity and cost increase significantly
Solution Approach 1:
The patent combines multiple separate components (slide for key-operated locking, connecting rod slide for emergency escape, and nut coupling mechanism) into a single integrated slide structure. This single slide performs all three functions: key-operated locking, emergency escape from inside, and external operation, thereby reducing component quantity while maintaining reliability
Solution Approach 2:
The single slide is designed as a universal component that performs multiple functions: it acts as the locking mechanism when key-operated, enables emergency escape when actuated from inside, and can be operated from outside when needed. This multi-functionality eliminates the need for separate dedicated components for each function
2Device complexity
If a single slide controls both key-operated locking and emergency escape functions, then component count is reduced, but the control mechanism becomes more complex
Solution Approach 1:
The slide is segmented into distinct functional zones: a key-operated section for locking control, an emergency escape section actuated from inside, and an external operation section. Each segment responds to different inputs but integrates into a unified control mechanism, making the complexity manageable through functional segmentation
3Reliability
If traditional multi-component locking mechanisms are used, then reliable locking is achieved, but the lock cannot be operated from the outside without additional handles
Solution Approach 1:
The patent merges the external operation function directly into the single slide structure, eliminating the need for separate external handles. The slide can be actuated from outside directly, combining the locking and external operation functions into one integrated mechanism

AI summary
The invention relates to a method for operating a panic lock (1), in which a building interior side spindle and a building exterior side spindle are provided which respectively interact with divided spindle-hole halves of a spindle hole (17), and in which the spindle-hole halves can be coupled using means (16, 16', 17), wherein the latch (6) and bolt (5) in the closed door leaf reach the locking position by means of a force accumulator, and an espagnolette slider (13) arranged in the main lock case (2) interacts with the bolt (5), and wherein a trigger (9) is assigned to the latch (6), which trigger, in the case of a closed door leaf and protruding latch (6), interacts in a triggering way with a frame part, by which means the latch (6) and the bolt (5, 7) lock. In order that a simple and efficient function selection of the panic lock can be carried out between automatic locking using the activated and deactivated external spindle, a slider (20) is provided which is displaceable by key activation via a lock cylinder and controls a latching mechanism (24, 23, 27) which holds the espagnolette slider (13) in an unlocked position, and applies the means (16, 16', 17) for coupling the spindle-hole halves.
