Definitions

  • the present invention relates to a loop for laces with rapid lace disengagement.
  • the loop for laces according to the invention is particularly suitable for safety shoes such as boots for building site workers and/or sports footwear.
  • the user while performing normally his duties, may in fact become caught with the shoe in a position and/or location that he must clear as rapidly as possible.
  • One known type of loop comprises a shaped base, to be fixed to the upper of the shoe, above which a lever is articulated; said lever has a front portion that is shaped like an eye and a rear portion that is available to the user and is normally arranged close to said base.
  • the eye has a radial opening normally closed by a front portion of the base.
  • loops of this type do not have a particularly tough structure.
  • Another type of known loop comprises, on a base to be fixed to the upper, a lever which has a front portion, which is articulated proximate to the opening of the shoe above the base, and a rear portion, which is arranged opposite with respect to the opening of the shoe relative to the articulation region and is hook-shaped for the engagement of the lace.
  • the rear hook-shaped portion has an elongated upper end that is available to the user.
  • the lever which normally rests on the base, provides with said base a cam-like coupling that contrasts its opening on the part of the user.
  • the aim of the present invention is to provide a loop for laces with rapid lace disengagement that solves or substantially reduces the problems of known type of loop for laces.
  • an object is to provide a loop for laces in which a variation in the direction of the tension of the lace in no way causes the disengagement of said lace.
  • Another object is to provide a loop for laces that is safe and sturdy.
  • Another object is to provide a loop for laces that has a low cost.
  • a loop for laces with rapid lace disengagement comprising a base to be fixed to the upper of a shoe, above which a lever is articulated, said lever having a hook-shaped head portion for the engagement of a lace and a tail portion that is available to the user for rapid disengagement, said lever being able to rotate with respect to a transverse articulation axis from a closed position, for the engagement of said lace, with said tail portion rested on said base, to an open position, for the disengagement of said lace, said articulation axis being arranged so as to generate, when the lace is pulled, a moment that always acts so as to close said lever.
  • a loop for laces according to the invention in a first embodiment, is generally designated by the reference numeral 10.
  • the loop 10 comprises a base 11 to be fixed to an upper 12 of a shoe, for example by means of a rivet 30, above which a lever 13 is articulated; said lever has a hook-shaped head portion 14 for the engagement of a lace 15 and a tail portion 16, which normally rests on the base 11 and has a free end 26 available to the user for rapid disengagement.
  • the lever 13 is articulated, by means of a transverse pivot 20, with an end 17 of its hook-shaped head portion 14, on an upper portion 18 of the base 11, which is also hook-shaped.
  • the head portion 14 of the lever 13 is a fork, which is articulated on an end 19 of the upper portion 18.
  • the pivot 20 is applied to corresponding transverse through holes 28 and 29, which are formed respectively in the head portion 14 and in the upper portion 18.
  • the head portion 14 of the lever 13 and the shaped portion 18 of the base 11 form a continuous hook-like shape for the engagement of the lace 15.
  • the head portion 14 and the shaped portion 18 in fact have the same transverse profile.
  • the lever 13 can rotate with respect to its articulation axis from a closed position, for the engagement of the lace 15, with the tail portion 16 rested on the base 11, to an open position, for the disengagement of the lace 15, in which the tail portion 16 can rotate through more than 180 sexagesimal degrees.
  • the head portion 14 of the lever 13 can have a monolithic transverse pivot 120, which engages by snap action within a corresponding seat 21 formed in the shaped portion 18 of the base 11 through an upper opening 27.
  • the lateral portions 22 of the base 11, arranged laterally adjacent to the upper portion 18, have upper surfaces that are determined by the portion of space swept by the fork-shaped head portion 14 of the lever 13.
  • the head portion 14 moves so as to skim over the lateral portions 22 of the base 11.
  • the rear portion 23 of the base 11, on which the tail portion 16 of the lever 13 rests, has a profile that is shaped complementarily to said tail portion 16.
  • the lever 13 has a free end 26, which forms a step 25 with the base 11 and is available to the user in order to turn the lever 13 with respect to the base 11 and rapidly disengage the lace 15.
  • the loop for laces 10 is normally arranged so that the lever 13 rests on the base 11.
  • Figures 9 and 10 illustrate a second embodiment of the loop according to the invention, generally designated by the reference numeral 110.
  • the loop 110 is substantially similar, as regards its operating principle, to the loop 10, but differs geometrically from it in that the upper portion 118 of the base 111 is a fork on which the head portion 114 of the lever 113 is articulated by means of a transverse pivot 220.
  • the head portion 114 of the lever 113 and the shaped portion 118 of the base 111 provide a continuous hook-like shape.
  • the head portion 114 and the shaped portion 118 in fact have the same transverse profile.
  • the transverse pivot 220 can be applied or monolithic with respect to the upper portion 118 of the base 111 or to the head portion 114 of the lever 113.
  • the loop is therefore safe, reliable and tough and has a simple structure.
  • the materials may be any according to requirements.
