Definitions

  • the present invention relates to a fastening lever, particularly for sports shoes such as ski boots, roller skates, ice skates, or ice-climbing boots.
  • a problem encountered in sports shoes is to achieve optimum fastening of the flaps of a quarter or shell while maintaining good comfort.
  • a conventional fastening lever is generally constituted by a lever arm articulated to a base which is rigidly coupled to a first member of the shoe and by a spring traction member which is associated with a second member of the shoe.
  • the lever arm has, on its lower surface, a plurality of teeth for engaging the free end of the spring traction member, which is constituted by two parallel cylindrical springs which are mutually rigidly coupled at the free end of the traction member.
  • such "elastic" lever has the advantage that it allows effective and uniform mutual closure of the two flaps over each other, while the springs tend to compensate for the differences in adjustment that frequently occur among the various levers of the sports shoe.
  • a further drawback is that, during the fastening action, the two cylindrical springs are subjected to possibly considerable elongations, according to the intended fastening that can be imparted to the lever.
  • the springs are very large and are arranged outside the lever arm, in an exposed position, they are prone to breaking or at least to being damaged by impacts with objects, such as rocks, branches, other shoes, skis and anything else that might accidentally make contact with the sports shoe.
  • a further drawback is that dirt, mud and grass blades, or any other solid object, such as small fragments of rocks, pebbles or ice fragments, can easily penetrate between the springs, causing possible defects in the operation of the lever and also possible damage thereto.
  • a second conventional type of elastic lever is constituted by a lever arm, which is articulated to a base which protrudes from a first flap or member of a shoe, and by a traction member, which is associated with the second flap of the shoe and has elastically deformable parts.
  • Teeth protrude downward from the lever arm and engage the free end of the traction member, which is constituted by two telescopic members which contain mutually parallel elastically deformable members.
  • Each member has a hollow cylinder in which a piston is slidingly arranged, the piston being constituted by a head and a stem which protrudes outside the hollow cylinder in the opposite direction with respect to the second flap.
  • a cylindrical spring which is coaxial to the stem, is arranged so that it is compressed by the head of the piston when the stem slides toward the outside of the cylinder, so as to contrast the elongation of the traction member.
  • the stems of the pistons that lie outside the hollow cylinders are mutually connected so as to form the free end, which interacts with the teeth of the lever arm.
  • This second type of conventional elastic lever too has the advantage of allowing effective and uniform closure of the two flaps.
  • the lever in fact has a structure which is fully similar to the previously described conventional type of fastening lever and differs only in the type of elastically deformable member that is used.
  • This second conventional type of lever has drawbacks which are similar to those of the preceding fastening lever.
  • the lever arm is disadvantageous and the closure action becomes more and more difficult as the distance of the tooth used for connection to the free end of the traction member with respect to the pivoting point of the lever arm increases.
  • the telescopic members are difficult to manufacture, because they are composed of several parts, most of which are small, requiring expensive precision processes.
  • the aim of the present invention is to solve the above-noted drawbacks and the described technical problems, by providing a lever in which the user can achieve optimum comfort for the foot while maintaining a constant closure load.
  • An object of the invention is to provide a lever which provides for a constant closure load even when the flaps, by settling and elongating, tend to reduce the initial closure load of the lever.
  • Another important object is to provide a lever which reduces the number of adjustments of the closure of the various levers applied to the sports shoe.
  • Another object is to provide a lever whose closure does not entail the accidental opening of an adjacent lever.
  • Another object is to provide a lever in which it is possible to indicate the obtained closure load value.
  • Another object is to provide a lever which is structurally simple and has low manufacturing costs.
  • the reference numeral 1 designates a fastening lever particularly for sports shoes such as for example skates and ski boots.
  • the lever 1 has a base 2, which is rigidly coupled to a first flap 3 of the sports shoe.
  • the base 2 is flat and is laterally provided with two shoulders 4a and 4b that protrude at right angles to the first flap 3 and face each other so that a lever arm 5 can be articulated between them.
  • the lever arm 5 is U-shaped so as to form two wings 6a and 6b that are pivoted, at their respective free ends, to the two shoulders 4a and 4b, by means of two first pivoting members 7a and 7b, respectively.
  • a traction member designated by the reference numeral 9, is pivoted between the two wings 6a and 6b, preferably in an intermediate position, by means of a shaft 8.
  • the traction member 9 has an approximately central longitudinal through slot 10 accommodating the shaft 8 for the pivoting of the traction member 9 to the pair of wings 6a and 6b.
  • the traction member 9 has a sleeve 13 which has a smaller diameter and is internally threaded in order to receive the stem of a screw 14.
  • the sleeve 13, by having a smaller diameter than the traction member 9, has a step-like surface 15 adapted to blend with the traction member 9.
  • the surface acts as an abutment for an annular member 16 having a C-shaped cross-section.
  • the shaft 8 slides within the through slot 10 in contrast with an elastically deformable member 17, which is preloaded and interposed between the head of the screw 14 and the annular member 16.
  • the elastically deformable member 17, which is for example constituted by a cylindrical spring, keeps the closure load of the lever 1 constant.
  • the traction member 9 is rotatably associated with a bridge 18, by means of, second pivoting members 19.
  • the bridge 18 is U-shaped and has a pivot 20, at its free end. Pivot 20 is arranged transversely to the traction member 9 and is adapted to be selectively associated with one of a plurality of teeth 21 protruding from a rack 22.
  • the teeth 21 protrude from the rack 22 preferably approximately at right angles to a second flap 23 which is arranged above the first flap 3 with which the rack 22 is associated.
  • the teeth 21 In a transverse cross-section, the teeth 21 have a shape which is curved in the opposite direction with respect to the traction member 9, so as to prevent any motion of the pivot 20 towards the traction member 9.
  • the arrangement of the traction member 9 between the first flap 3 and the plane that passes between the first pivoting members 7a and 7b and the shaft 8 allows to lock the lever 1 in the intended position.
  • the shaft 8 performs a translatory motion, inside the slot 10, toward the screw 14, pressing on the annular member 16 and thus compressing the spring 17 until its turns are placed in mutual contact ("packed" arrangement of the spring).
  • the settling of the foot inside the sports shoe entails that the first and second flaps of the shoe have adapted and mutually overlapped more extensively.
  • the spring 17, preloaded in closure compensates, by elongating, for the greater overlap of the flaps, moving the screw 14 away from the annular member 16 and thus keeping the traction member 9 in traction.
  • the lever 1 allows quicker and simpler fastening of the various levers arranged along the quarter and the shell, because the spring 17 allows to compensate for the differences that are inevitably present among the fastening forces of the various levers.
  • the fastening lever also allows more rapid and effective closure of the sports shoe, avoiding a plurality of adjustments of the fastening levers.
  • Figures 9 to 12 show a fastening lever 101, according to a further aspect of the invention, comprising a first base 102 which is rigidly associated with a first flap 103 of a sports shoe.
  • the first base 102 is flat and laterally provided with two shoulders 104a and 104b, which protrude at right angles to the first flap 103 and face each other so that a lever arm 105 can be articulated between them.
  • the lever arm 105 is U-shaped so as to form two wings 106a and 106b pivoted to the pair of shoulders 104a and 104b by means of a pair of first pivoting members 107a and 107b respectively.
  • a shaft 108 is arranged between the pair of wings 106a and 106b, in an intermediate position.
  • the shaft 108 allows for the pivoting of a first end 130a of an elastically deformable member, such as a cylindrical spring 117, which is associated with a traction member 109 at its second end 130b.
  • an elastically deformable member such as a cylindrical spring 117
  • the traction member 109 is rotatably associated, at its free end, with a bridge 118, by means of second pivoting members 119.
  • the bridge 118 is U-shaped and has a pivot 120, at its free end.
  • the pivot 120 is arranged transversely to the traction member 109 and can be selectively associated with one of a plurality of teeth 121, protruding from a rack 122.
  • the teeth 121 protrude from the rack 122 preferably approximately at right angles to a second flap 123 which is arranged above the first flap 103, with which the rack 122 is associated.
  • teeth 121 In a transverse cross-section, teeth 121 have a shape which is curved in the opposite direction with respect to the traction member 109, so as to prevent any motion of the pivot 120 towards the traction member 109.
  • lever 101 The operation and the advantages of the lever 101 are similar to those of the lever 1, and in this case too the elastically deformable member keeps the closure load during the use of the shoe constant.
  • the lever 101 is simpler and cheaper than the lever 1, according to the first aspect of the invention, because it is constituted by a reduced number of component parts.
  • the lever 101 is of the advantageous type, since it allows the user to perform a first step of the closure of the lever without affecting the elastically deformable member and therefore without using considerable closure forces.
  • the elastically deformable member is activated only during the last step of the closure of the lever arm, in which it is already partially turned.
  • the position of the lever arm which is almost parallel to the first flap, allows to produce a low force to complete the closure action, simultaneously achieving the packed, or almost packed, compression of the elastically deformable member.
  • Figs. 13 to 15 show a fastening lever 201 according to still a further aspect of the invention and comprising a base 202, which is slidingly associated with a first flap 203 of the sports shoe.
  • the base 202 can in fact slide longitudinally by means of a sliding guide constituted by a longitudinal slot 204, which is formed along the central line of the base 202.
  • a rivet 205 has a stem 206 interposed between the base 202 and the first flap 203 and a pair of heads 207a and 207b, and is adapted to engage the longitudinal slot 204.
  • the base 202 is flat and laterally provided with two shoulders, 208a and 208b, protruding at right angles to the first flap 203 and facing each other so that a lever arm 209 can be articulated between them.
  • Two wings 210a and 210b protrude from the pair of shoulders 208a and 208b toward the end of a second flap 222 to be joined to the first flap 203 and lie on a plane which is approximately perpendicular to the first flap 203 and to the pair of shoulders 208a and 208b.
  • the base 202 can slide along the first flap 203 in contrast with a pair of elastically deformable members 211a and 211b interposed between the pair of wings 210a and 210b and a connecting member, constituted by a resting member 212.
  • Two resting surfaces 212a and 212b protrude from the resting member 212, which is associated with the first flap 203, and respectively face the pair of wings 210a and 210b.
  • the elastically deformable members 211a and 211b constituted by a pair of helical cylindrical springs, keep the closure load of the lever 201 constant.
