AI Technical Summary
High-speed roller doors used in cold storage or freezer rooms face challenges in achieving rapid opening and closing while maintaining a tight seal without requiring excessive force, as increased airtightness leads to higher opening forces.
A high-speed roller door design featuring a curtain that can be wound around a horizontal shaft, a pressure frame applying force transverse to the door frame for a tight seal, and mechanically active control means on the curtain side to space the pressure frame during opening, eliminating the need for a separate drive for the pressure frame.
Enables rapid opening and closing with a tight seal, reducing frictional forces and ensuring secure closure without pressurizing the sealed space, using structurally simple and reliable mechanisms.
