Definitions

  • the present invention relates to a lever arm particularly for sports shoes.
  • levers which comprise a base which can be coupled rigidly to a flap of the shoe and from the longitudinal ends of which there protrude approximately at right angles two tabs between which a lever arm is rotatably associated.
  • the lever arm typically made of folded or stamped metal plate, or alternately of rigid plastic material, is approximately U-shaped in plan view, and has an approximately flat head adapted to be gripped by the user and from one end of which two arms protrude approximately at right angles, such arms being pivoted, at their free end, to the tabs of the base.
  • a pivot is supported transversely between the head and the free ends of the arms, and a hollow cylinder is rotatably associated with said pivot, is threaded internally and is open at its end which is directed away from the head; a complementarily threaded shaft is associated axially with the cylinder and its free end is associated rotatably with an element for temporary connection, such as for example a grip ring or tooth for a rack, which can be associated with a second flap of the shoe.
  • lever arm has a drawback: if they are made of metal plate, they can in fact have sharp or pointed edges, which can injure the user during operations for opening and fastening the shoe, especially if the operation is performed with one's bare hands; in this case, the low temperature of the environment makes the fingers less sensitive, consequently making it less likely for the user to notice promptly any cuts in his/her skin.
  • lever arm made of plastic material do not suffer the drawbacks mentioned above but have the disadvantage that they are more fragile than metal ones and therefore are not suitable for example for use for competitive practice, during which the shoe is subjected to intense stresses which might break them.
  • the aim of the present invention is to solve the above-mentioned problems, eliminating the drawbacks of the cited background art, by providing a lever arm, particularly for sports shoes, which can be used safely by the user.
  • an object of the present invention is to provide a lever arm which is reliable and strong and therefore can be used both in amateur practice and in competitive practice, maintaining its strength characteristic at a high level.
  • Another object is to provide a lever arm which is structurally simple and has low manufacturing costs.
  • a lever arm particularly for sports shoes, which can be associated with a base which can be rigidly coupled to a first flap of a shoe from which two first perforated tabs protrude, characterized in that it is constituted by a rigid wire-like element which is approximately U-shaped so as to form two first arms which are folded, at a first end, so as to form seats for first means for pivoting to said pair of first tabs, a stiffening cage being associated with said wire-like element and having second pivoting means for an element for interconnection to means for engaging a second flap of said shoe.
  • the reference numeral 1 generally designates a lever arm, particularly for sports shoes, which can be associated with a base 2 which can be rigidly coupled to a first flap of the shoe, which is not shown in the accompanying figures.
  • the base 2 has an approximately flat surface 3 and an approximately rectangular plan shape with appropriately rounded corners, from the longitudinal perimetric edges of which there protrude, approximately at right angles and preferably proximate to one of its ends, two first tabs 4a, 4b, which are mutually parallel and on which two first holes 5a, 5b are formed along a same axis.
  • the lever arm 1 comprises a rigid wire-like element 6, which is preferably provided by means of a metal wire which is appropriately treated and bent until it assumes an approximately U-shaped plan configuration, in which there are two first arms, designated by the reference numerals 7a and 7b, which are bent so as to form a curl at their first ends 8a, 8b so as to form respectively two seats 9a, 9b for first means for pivoting to the pair of first tabs 4a, 4b.
  • the first ends 8a, 8b of the first arms 7a, 7b have such a mutual distance as to allow their placement, during use, in the interspace and adjacent with respect to the first tabs 4a, 4b, respectively, of the base 2, preferably in engagement with their lateral surfaces, which face each other; advantageously, the first ends 8a, 8b are rotatably coupled to the contiguous first tabs 4a, 4b by means of the first pivoting means, which are constituted for example by two rivets 10a, 10b, which can be arranged in the first holes 5a, 5b and in the seats 9a, 9b.
  • the two first arms 7a, 7b are connected, on the opposite side with respect to the first ends 8a, 8b, to a first base 11, which has in plan view an approximately teardrop-shaped configuration so as to form two arms, designated by the reference numerals 12a and 12b, which are mutually connected at the vertex 11a of the first base 11.
  • the arms 12a, 12b are approximately V-shaped and comprise first portions 13a, 13b which are substantially straight and are connected respectively to the first arms 7a, 7b and mutually diverge away from said arms.
  • the first portions 13a, 13b are connected, at the opposite end with respect to the first arms 7a, 7b, respectively to two second portions, designated by the reference numerals 14a, 14b, which are inclined by a suitable angle with respect to the first portions 13a, 13b and mutually converge toward the vertex 11a of the first base 11.
  • a stiffening cage 15 is associated with the wire-like element 6 and is constituted preferably by a plate 16 which is conveniently flat and preferably made of metal or plastic material and advantageously has an approximately U-shaped plan configuration; advantageously, the cage 15 can be associated in an upper region with the wire-like element 6 by way of suitable engagement means described hereinafter.
  • the plate 16 has a second base 17, which is arranged between the first portions 13a, 13b and from which two second arms 18a, 18b protrude approximately at right angles and are arranged, during use, above the first arms 7a, 7b of the wire-like element 6.
  • the dimensions of the second arms 18a, 18b are such that they protrude laterally beyond the underlying first arms 7a, 7b of the wire-like element 6, so as to surround them at least partially.
  • the second base 17 acts as a reinforcement to avoid possible deformations of the wire-like element 6 transversely thereto, thus increasing its solidity.
  • the second free ends 19a, 19b of the second arms 18a, 18b are folded so as to partially wrap around the underlying first arms 7a, 7b of the wire-like element 6, so as to constitute said means for engaging the cage 15 with the wire-like element 6.
  • the cage 15 further comprises two wings, designated respectively by the reference numerals 20a and 20b, which protrude at the connecting region between the first arms 7a, 7b and the second base 17 and are inclined with respect to the latter, so as to be superimposed during use on the first portions 13a, 13b of the first base 11 of the wire-like element 6.
  • the third free ends 21a, 21b of the wings 20a, 20b are folded so as to wrap around the underlying first portions 13a, 13b of the wire-like element 6, so as to form additional means for engaging the cage 15 with the wire-like element 6.
  • the cage 15 has second pivoting means for an element 22 for interconnection to appropriately provided means for engaging a second flap of said shoe, not shown in the accompanying figures.
  • Such second pivoting means advantageously comprise two second tabs 23a, 23b, which protrude approximately at right angles from the non-facing longitudinal perimetric edges of the second arms 18a, 18b and in the direction of the underlying first arms 7a, 7b of the wire-like element 6 and have such dimensions as to protrude downward from them.
  • the interconnection element 22 is constituted by a hollow and internally threaded cylinder 26, and is open at its end which is directed away from the second head 17 of the cage 15, in which a through opening 26a is provided transversely and within which the pivot 25 can be accommodated.
  • a complementarily threaded shaft 27 is associated inside the cylinder 26 and its free end is associated rotatably with said grip means, which are constituted for example by an engagement tooth 28, which can be associated selectively with a rack 29 which in turn is associated with a second flap of the shoe, not shown in the accompanying figures.
  • the lever arm according to the invention is therefore as follows.
  • the cylinder 26 is arranged between the second tabs 23a and 23b of the cage 15 and is then rotatably associated with them by means of the pivot 25.
  • the first ends 8a, 8b of the first arms 7a, 7b of the wire-like element 6 are then associated rotatably with the first tabs 4a, 4b of the base 2 by means of the rivets 10a, 10b, and the latter can be fixed to a first flap of a shoe, which is not shown in the accompanying figures.
  • lever arm according to the invention is very strong and therefore can be used both for amateur practice and for competitive practice; in particular, a lever arm in which the cage is made of plastic material (which is cheaper but less strong than metal) can be used advantageously for amateur practice, while a metal cage can be preferred in competitive practice.
  • lever arm according to the invention can be provided with production costs which are lower than those of known types of metal lever arm.
