Patent DE-2422666-A1 (DE)
Title: Automatically folding sealing strip for door - is for use where door does not come into contact with frame or beam
IPC: E06B7/20
Filed: 1974-05-10
Abstract: In the closed position, the sealing strip is pressed onto the frame and folds downwards. A wheel or a roller can limit the frictional resistance. As soon as the pressure of the frame weakens, the sealing strip is moved back into its initial position by the natural elasticity of the material. This return movement can also be effected or strengthened by the use of spring force. Transmission of the movement forces can occur through the use of a hinge. The seal is designed to be fully weather-proof. In order to guarantee that the sealing strip folds downwards in a uniform manner a rigid rail is brought into contact with it.
