ABSTRACT:
A device for slowing a downward movement of a sliding door of a wardrobe includes a free-wheel consisting of a driving portion and a driven portion. The driven portion is coaxially aligned with the driving portion and is provided with an external toothing. The device also includes a driving rope running through the free-wheel driving portion which is fastened at one end to the sliding door and at another end, by interposition of a tension spring, to a base of the wardrobe. Additionally a spring is arranged between the free-wheel driving and driven portions and is used to engage the two free-wheel portions during the downward movement of the sliding door and to disengage the two during upward movement of the sliding door. A centrifugal brake is coupled to a spindle which is provided with an external toothing cooperating with the external toothing of the free-wheel driven portion. The centrifugal brake is used to generate a resisting torque capable of braking the free-wheel driving and driven portions and slowing the downward movement of the sliding door.
