Strap winder, the following description of the operation of a shutter or roller blind comprising such a winder and method of adjusting the tension of the spring, such a winder

摘要

This winder (101) comprises a spring (106), a first end is integral with a ring (105), - even secured to the strap or the like (102), whereas the second end of the spring is fixed to a sleeve (104) disposed around a pin (107) integral with a body (108) of the winder (101). The ring (105) and the sleeve (104) together form a housing (103) for the spring (106), the ring being able to rotate around the sleeve. The means (110) of selective interlocking of the sleeve (104) and of the pin (107) are adapted to immobilize the sleeve in rotation about said pin in a first configuration and to allow the rotation of the sleeve about the pin in a second configuration.il is thus possible to adjust the activation of the spring while maintaining the ring (105) and the strap (102) is attached and by rotating the sleeve (104) about the axis of symmetry (x - x ′) of the pin (107).
