Cubicle Door Locking Device with Retractable Emergency Section
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cubicle door designs with inwardly opening mechanisms pose challenges in emergency situations, where an occupant may obstruct the door's inward opening, and are vulnerable to forced impacts that cause the door to bend and potentially swing outward, compromising security and access.
Innovation Solution
A locking device with a retractable section that extends from a fixed base section, allowing the door to pivot outward in emergencies while inhibiting lateral movement during normal use, featuring protrusions or grooves for alignment and biasing mechanisms to maintain the door's position, and a stop member to prevent excessive pivoting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the door is designed to open inwardly only, then the pilaster prevents the door from opening outwardly, but in a medical emergency the occupant becomes an obstacle to the door opening inwardly
Solution Approach 1:
The pilaster is made movable between a first position (preventing outward opening) and a second position (allowing outward opening). This dynamic transformation allows the structure to adapt between normal security mode and emergency access mode, resolving the contradiction between door security and emergency accessibility
2Reliability
If the door slightly overlaps the pilaster, then there is no sight line from exterior into interior, but forced impact can cause bending of the door which allows it to pass beyond the pilaster and swing outwards
Solution Approach 1:
The inhibiting means is pre-installed to counteract the potential harmful effect of forced impact before it occurs. When the door is closed, the inhibiting means actively prevents the door from moving laterally relative to the locking device, countering any attempted forced entry or vandalism before it can compromise the cubicle security

AI summary
A locking device (10) for a door (100) of a cubicle (110), the locking device (10) comprising: a fixed base section (20) provided at the side wall (112); and a retractable section (30) which laterally extends from the base section (20) to a normal use position in which the door (100) is prevented from pivoting outwards from a closed position, wherein the retractable section (30) is movable to an emergency use position in which the door (100) is free to pivot outwards from the closed position, and wherein the locking device (10) includes inhibiting means adapted to inhibit lateral movement of the door (100) relative to the locking device (10) when the door (100) is in a closed position.
