Abstract
An assembly including a ratchet tightening device and a band. The device includes a base, a driving lever, and a pawl. For at least one tooth of a series of serrations of the band, at least one straight line tangent to the meshing surface of the tooth and parallel to the band, forms, together with the longitudinal direction of the band, an angle that is less than 90 degrees. A driving end of the lever is configured to cooperate with the serrations of the band. A retaining zone of the pawl is configured to cooperate with the serrations of the band.
Claims16
An assembly comprising:
- a band extending lengthwise in a longitudinal direction, from a fastening end to a free end;
- the band comprising serrations, said serrations including a succession of teeth extending in said longitudinal direction;
- a ratchet tightening device comprising:
- a base;
- a driving lever articulated to the base and including a driving end for driving the band along a first direction and a handling end;
- a pawl articulated on the base and having a retaining zone provided to oppose displacement of the band along a second direction opposite the first direction;
- and
- an elastic mechanism constantly biasing the retaining zone of the pawl towards the base;
- for at least one tooth of said succession of teeth of the band, at least one straight line tangent to a meshing surface of the one tooth and parallel to a surface of the band forms, together with the longitudinal direction of the band, an angle less than 90 degrees;
- the driving end of the lever being structured and arranged to cooperate with the succession of teeth of the band;
- the retaining zone of the pawl being structured and arranged to cooperate with the succession of teeth of the band.
A snowboard binding assembly for binding a snowboard boot to a snowboard, said assembly comprising:
- at least two straps, at least one of said straps including a ratchet tightening device and a band;
- the band extending lengthwise in a longitudinal direction, from a fastening end to a free end;
- the band comprising serrations, said serrations including a succession of teeth extending in said longitudinal direction;
- the ratchet tightening device comprising:
- a base;
- a driving lever articulated to the base and including a driving end for driving the band along a first direction and a handling end;
- a pawl articulated on the base and having a retaining zone provided to oppose displacement of the band along a second direction opposite the first direction;
- and
- an elastic mechanism constantly biasing the retaining zone of the pawl towards the base;
- for at least one tooth of said succession of teeth of the band, at least one straight line tangent to a meshing surface of the one tooth and parallel to a surface of the band forms, together with the longitudinal direction of the band, an angle less than 90 degrees;
- the driving end of the lever being structured and arranged to cooperate with the succession of teeth of the band;
- the retaining zone of the pawl being structured and arranged to cooperate with the succession of teeth of the band.
