<p>A shock-absorbed stop device or rolling shutters or sectional doors, capable of automatically intervening in case of accidental descend of the shutter, and adapted to dissipate by friction the kinetic energy accumulated by the shutter. Said device (A) comprises a bearing case (1) wherein a cursor (B) is enclosed and braked by a pair of jaws (15) associated with a tightening screw (14) contained inside the bearing case (1), the head (14a) of which can be anyhow accessed from the outside of the case (1) through a hole (1 c) obtained on one (1 b") of the two lateral walls (1 b' and 1 b") of the case (1), which is also provided with a window (10) through which the cursor (B) can be reloaded.</p> |
