Definitions

  • the present invention relates to a lever particularly usable for sports shoes such as ski boots, ice skates, or roller skates.
  • levers that are for example constituted by a lever arm which is pivoted at one end to two shoulders.
  • the shoulders are rigidly coupled to a first flap to be closed and the lever arm has a rack, towards the surface of the shoe.
  • a ring selectively interacts with the rack, and at its other end the ring is rigidly coupled to the second flap to be closed.
  • levers have a U-shaped lever arm.
  • a bar is associated between the wings of said arm and is associated by means of a coupling element with a cable or band or ring that interact, at their other end, with a rack that is associated with the second flap to be closed.
  • Italian patent no. 755,249 is known as a partial solution to this drawback and discloses a lever-like closure device for ski boots and sports shoes in general which is essentially constituted by a base plate which is essentially T-shaped and is rigidly coupled, at its corners, by a flap to be joined. Two parallel sides, provided with recesses which are open upward, protrude from its stem.
  • a closure lever is also articulated to the base plate approximately at the connection between the stem and the head.
  • the lever has, in the direction of the flap to be closed, notches at which it is possible to place a ring which is rigidly coupled, at its other end, to the other flap to be closed.
  • this assembly must be performed very precisely, like the execution of the recesses and of the notches, since any inaccuracy would prevent the placement of the ring between the notches and the recesses.
  • Italian utility model no. 189,418 discloses a lever for closure hooks, particularly for ski boots, which comprises a plate for fixing to a boot which has two lugs to which a lever for actuating the closure hook is pivoted.
  • a protrusion is formed on the lever at the pivot of the lugs and is adapted to snap into a seat which is associated with the plate, to prevent rotation of the actuation lever while the closure hook is not subjected to traction.
  • the seat is formed at an adapted elastic blade which is coupled to the plate.
  • the aim of the present invention is to solve the described technical problems, eliminating the drawbacks of the prior art and thus providing a lever that can maintain its closed condition even if the traction element, associated therewith to close the flaps of the shoe, is not subjected to traction.
  • an important object is to provide a lever that is structurally very simple and easy to activate and deactivate for the user.
  • Another object is to provide a lever that allows the user to perform no additional effort during closure and opening in order to achieve the intended aim.
  • Another important object is to provide a lever that can be activated even for an extremely large number of operations while always maintaining in optimum conditions the characteristic of its aim.
  • Another object is to provide a lever that has low manufacturing costs and can be obtained with conventional and known systems.
  • a lever particularly for sports shoes comprising a lever arm articulated to a closure member and having a pivot arranged between two teeth of a rack that is associable with another closure member to be closed, characterized in that said lever arm has means for engagement with complementarily shaped seats formed laterally with respect to said rack to retain said pivot between said two teeth.
  • the reference numeral 1 designates the lever particularly usable for sports shoes, comprising a lever arm 2 articulated to a closure member constituted by a flap, or by a traction element 3, and having a pivot 4, at one end.
  • Pivot 4 can be arranged between two adjacent teeth 5 of a rack 6 that is associable with the other flap to be closed.
  • Teeth 5 have a seat 7 connected to the preceding tooth and to the following tooth respectively, by means of a first vertical wall 8 and a second vertical wall 9.
  • This shape prevents the pivot 4, once accommodated in the seat 7, from leaving the seat because of a force applied along an axis that lies at right angles to said first and second walls.
  • the lever arm 2 also has engagement means which are constituted by at least one protrusion 10 that protrudes internally at at least one of the arms 11a, 11b of lever arm 2.
  • Protrusion 10 is substantially curved and can be arranged, when the lever arm 2 rotates towards the rack 6, at one of several complementarily shaped seats 12 formed at the lateral surfaces of said rack 6.
  • the protrusion 10 can thus be removably located at said seats 12 during the rotation of the lever arm 2.
  • a set of teeth 13 is formed at each side of the rack 6 and protrudes approximately as much as the protrusion 10.
  • the protrusion 10 prevents the lever arm 2 from lifting even in the absence of any traction force at the traction element 3 or even in the presence of a negative force, i.e. a force directed towards the rear part of the lever arm, since the particular curved shape of the protrusion 10 and of the complementarily shaped seats 12 opposes a movement at right angles to the rack 6.
  • said protrusion Due to its curved shape, said protrusion also prevents opening actions performed along directions that form an acute angle assuming a vertex directed towards the rack on the side opposite to the one adjacent to the flap to be closed and assuming a counterclockwise rotation.
  • the lever arm 2 can be released only by rotating it through such an angle as to disengage the protrusion 10 from the seat 12 formed by the set of teeth 13.
  • the seats 12 in fact contrast loads directed vertically with respect to the rack, whereas the seats 7, which are vertical with respect thereto, contrast the longitudinal loads orientated against the traction load, so that when the lever is closed any movement that might cause disengagement is prevented.
  • Deactivation is also very easy, since it is sufficient to rotate the lever arm by a preset angle, without having to apply additional efforts.
