A device for adjusting and clamping the toothed strap of a fastening for sports footwear, comprising a base, a ratchet mechanism for stopping the strap, and a ratchet mechanism for advancing the strap, the stopping ratchet mechanism comprising a first lever pivotable on the base for pivotal movement about a fulcrum and defining therewith a passageway for the strap, at least one tooth being provided on the first lever for engaging the teeth of the strap in order to constitute a stopping pawl of the stopping ratchet mechanism, the advancing ratchet mechanism comprising a second lever for engaging the teeth of the strap in order to advance the strap, characterized in that the second lever of the advancing ratchet mechanism is articulated to the first lever of the stopping ratchet mechanism for pivotal movement about a pin spaced from said fulcrum.
A fastening for ski boots and similar sports footwear with a device for adjusting the tensioning of a toothed strap and for clamping the strap in a passageway defined in a base for anchoring the device to a ski boot, characterised in that the device comprises:
- a) a ratchet mechanism for stopping the strap in the passageway, including
- a first lever having an operating end, its other end being pivotable with a movable fulcrum on shoulders of the base,
- at least one pawl projecting from the lever towards the base,
- means for guiding and limiting the angular movements of the first lever about the fulcrum,
- b) a ratchet mechanism for advancing the strap through the passageway, including
- a second lever pivotable on the first lever close to the operating end thereof and having a respective operating end outside of the movable fulcrum of the first lever,
- a pawl projecting from the second lever towards the base.
