A slider-and-channel release lets a revolving door fold open in emergencies while keeping the door leaf connected to the driving shaft.

Sensors and AI count users inside a turnstile to block piggybacking and allow only one authorized person through.

Foil conductors and integrated brush arrangements power door-wing displays while removing exposed edges that raise injury risk.

Lateral offsets between inner and outer drum glass hide support profiles, enabling a pre-assembled roof with cleaner appearance and faster installation.

Inner and outer glass offsets nest support profiles, reducing field assembly while preserving structural integrity and appearance.

This case uses seals that extend when stationary and retract during rotation to limit air leakage, friction, wear, and energy use.

A revolving door motor features a central through hole that allows cables to pass directly through the drive unit.

A passage lock uses a horizontally rotating ring segment to allow smooth transit for wheeled luggage and strollers.

Filling a hollow base body cavity with solid material increases flexural rigidity while maintaining lightweight operation against sabotage.

Segmented lock elements prevent simultaneous opening of adjacent doorways to optimize cockpit installation space while maintaining security.

Slidable door wing parts shift between extended and retracted positions to balance draught resistance with rapid human passage speed.

Evaluation unit detects freewheeling rotation and applies electrical signals to cancel stator currents.

Segmented drive rings with pivoting hooks reduce ceiling weight and height while maintaining structural strength.

Segmented carriers distribute wind loads to reduce twisting moments, resolving the trade-off between modular ease of manufacture and structural strength.

A revolving door entrance system adjusts opening width via movable door leaves to manage traffic flow.

Sensors trigger integrated light sources to emit visual warnings, preventing users from entering secured areas and maintaining turnstile rotation speed.

Magnetic clamping secures heavy glass panes during assembly, eliminating manual handling errors and improving positioning accuracy.

Sensors detect pedestrian presence and trigger a securing mechanism to release door wings, enabling free pivoting during heavy traffic or power loss.

An optical pattern occlusion mechanism detects objects in revolving door sectors, resolving unauthorized access risks while maintaining operational ease.

Segmented sliding door parts separate during emergencies to provide free egress without swiveling door wings around a central post.

Motor-driven rotating entrance assembly reduces access time by replacing heavy hinged doors with segmented shielding components.
