ABSTRACT:
A hose reel includes a support casing, a drum rotatably fitted inside the casing and connected to it by an elastic rewinding element. The drum provides a flange integral with it and couplable in rotation with a locking disc equipped with teeth engageable with opposing teeth capable of stopping its rotation. An elastic separator is provided between the flange and the locking disc to keep the latter in a first position axially distanced from the flange, teeth and counter-teeth mutually engaged to allow the flange to draw the locking disc into integral rotation with it, and cam and counter-cam which, in the event of the flange exceeding a predetermined threshold speed cause the axial displacement of the locking disc into a second position adjoining the flange in which its teeth engage with the opposing teeth to produce the consequent stopping of the rotation of said drum.
