Definitions

  • This invention relates to a ratchet pawl device for coupling with a serrated strap of a closure lever, particularly for ski boots.
  • That ratchet device or mechanism consists essentially of a small lever which is pivoted at its middle and has a first toothed end adapted to engage with the strap serrations so as to inhibit translation of the strap in a withdrawing direction extending away from the base and to enable translation of the strap in an inserting direction by oscillating said small lever.
  • the adopted configuration allows then, as mentioned above, the lever to be oscillated to allow the strap through the ratchet mechanism in order to adjust its working length; further, the first toothed end of the lever may be disengaged from the serrated strap by acting on the second end of the lever, which will move the first end away and release the serrated strap.
  • the ratchet mechanism just described has the disadvantage of not providing a ' reliable locking action with the lever in the closed position.
  • the cited lever in use, is specially exposed to shocks at its second end, and consequently liable to release the serrated strap from its coupling and alter the tightening action applied by the closure lever.
  • Another object of this invention is to provide a ratchet pawl device as indicated which, while notably having improved features, is structurally simple and requires no special or difficult procedures for its operation.
  • Still another obect of this invention is to provide a ratchet pawl device as indicated, which can be readily manufactured from commercially available elements and materials, and which is competitive from a purely economical standpoint.
  • a ratchet pawl device for coupling with a serrated strap of a closure lever, particularly for ski boots, according to the invention, comprising a base attachable to one of the flaps to be brought together and having lateral sides bounding the area of engagement for a serrated strap connected to a lever associable with the other of the flaps to be brought together, also provided being an oscillable body hinged, at a middle portion thereof, to said sides and having a first toothed end engageable with said serrated strap to block translation of said serrated strap in a withdrawing direction extending from said base and to enable translation of said strap in an inserting direction extending through said base on oscillation of said oscillable body, said oscillable body having a second end actuatable for pivotally disengaging said first toothed end from said strap, said ratchet pawl device being characterized in that it further comprises a means of blocking the oscillation of said oscillable
  • a ratchet pawl device for coupling with a serrated strap of a closure lever, particularly for ski boots, according to the invention, as genrally indicated at 1, comprises a base 2 having a center portion 3 formed with holes 4 for its attachment to one of the flaps to be brought together.
  • lateral sides 5 which are located oppositely to each other and substantially delimit the area of engagement for a serrated strap 6 which is connected, with one end thereof, to a closure lever, of a type known per se, which is generally indicated at 7.
  • the ratchet pawl device 1 further includes an oscillable body 10, which advantageously has a substantially flattened configuration and hingedly connectable, at a middle portion thereof, to a pin 11 supported on the lateral sides 5.
  • the oscillable body 10 has a first toothed end, indicated at 12, which is engageable with the serrations 6a on the serrated strap 6.
  • the serrations 6a of the serrated strap 6, and the teeth 12a on the toothed end 12, are shaped to effect blocking of the serrated strap, 6 preventing it from translating in a withdrawing direction (as indicated by the arrow 100 in figure 3), extending off the base 2, while they enable the serrated strap 6 to be inserted with a resultant oscillation of the body 10 about the hinge connection point.
  • the first toothed end 12 is held elastically in contact with the serrated strap by the elastic biasing action of a spring means which advantageously comprises a hairpin spring 15 associated with the pin 11 and having a first end 16 coupled with one of the sides 5 and the other end 17 received in a recess 18 defined in a side of the body 10.
  • a spring means which advantageously comprises a hairpin spring 15 associated with the pin 11 and having a first end 16 coupled with one of the sides 5 and the other end 17 received in a recess 18 defined in a side of the body 10.
  • the body 10 defines, at the opposite end from the first toothed end 12, a second end 19 whereon a pressure may be exerted to oscillate the body 10 about the hinge connection point against the bias of the spring 15 thereby removing the first toothed end 12 from its engagement with the serrations 6a of the serrated strap 6.
  • a peculiarity of the invention resides in the fact that the cited ratchet pawl device has a means of blocking the oscillation of the oscillable body 10 which is actuatable by the pull applied to the serrated strap by the closure lever, on tightening the closure lever; this is very important because it prevents any inadvertent striking against the body 10 from causing an undesired release or withdraw of the serrated strap from the ratchet mechanism.
  • Such locking arrangement is provided, in essence, by the provision for a limited translation of the body 10 relatively to its point of hinge connection such as to bring lugs 20 projecting laterally from the body itself into notches or locking seats 25 formed in the lateral sides 5.
  • the body 10 engages with the hinge pin 11 by means of a channel 21 which has, in cross-section, a substantially oval or otherwise elongate shape having a major axis extending in the direction of extension of the serrated strap.
  • the cited lugs are provided at the first toothed end 12 and may be formed of a throughgoing pin which projects laterally from the body 10, or may be formed integrally with the oscillable body 10 itself.
  • the cited lugs are receivable in the side notches or cutouts 25, defined by the sides 5, on engaging the pin 11 with the front portion of the oval channel 21, the front portion being herein the portion located at the end of the channel 21 which is remote from the closure lever 7.
  • the lugs 20 will not interfere with the notches 25, and accordingly, the body 10 can be oscillated in the traditional manner to disengage its toothed end 12 from the serrated strap.
  • the invention achieves its objects, and in particular that blocking of the oscillation of the oscillable body 10, with the serrated strap under tension, that is with the lever in the closed position, may be obtained in an extremely simple and quick fashion.
  • any materials so long as compatible with the specific use, as well as any dimensions and contingent shapes may be selected and used depending on requirements.
