Abstract (en)
[origin: EP1302620A2] Spring shaft for rollable flat bodies comprises a fabric shaft coupled to one end of a spring (6) whose other end is connected to a fixed clamping part (8). A coupling (25, 26) locking under the action of the axial tension of the spring prevents release of the spring. <??>Preferred Features: One part (26) of the coupling is provided on a spring guide rod (12) which is coupled to the tension part so that it cannot rotate, and the other part (25) of the coupling is provided on a spring receiving part (15) receiving the other end of the spring and connected to the fabric shaft so that it cannot rotate.
