Child-Safety Egress Engineering
In pediatric clinics and residential nursery suites, standard thumbturns can be operated by toddlers. Push-to-Turn Cylinders introduce axial interlocking.
Mechanical Sequence
- Free-Spinning Idle: Rotating the knob without pushing spins freely.
- Axial Clutch Engagement: Depressing the knob axially by 3 mm engages internal drive dogs to retract the deadbolt.
