Definitions
- the present invention relates to a fastening device for a shoe.
- a shoe comprises an upper assembly, on the upper portion of which there is an opening.
- a shoelace is passed through such eyelets and, usually, the lace alternates its passage between an eyelet positioned on one side with passage through an eyelet of the opposite side, starting from the eyelets arranged proximate to the toe of the shoe.
- the two free ends of the shoelace are knotted, generally in a region proximate to the instep, in order to keep the shoelace under tension and ensure an adequate contact between the shoe and the foot of the user.
- a tongue which is adapted to be raised through the opening, after having loosened the shoelace, in order to facilitate the insertion of the foot into the shoe, or the exit thereof.
- the shoelace has no memory and it is therefore necessary that the user uses his or her own memory in order to carry out the various different necessary steps and perform the operation.
- an excessive tension applied to the shoelace or owing to the fixing knot, may cause a bothersome pressure on the foot.
- US 6,427,361B1 contains the teachings for providing a device for tightening and loosening the shoelace by way of a mechanism which is present between the layers that make up the sole and the upper.
- One end of the shoelace is affixed to the upper, and it enters the insole through an opening and is wound around a slider.
- a platform associated with the removable insole, is lowered, which slides the slider.
- the slider tightens the shoelace up until a locking position, which is constituted by a mechanical anchor.
- the mechanical coupling is automatic and snap-acting.
- the fastening position coincides with the position in which the foot of the user is completely inserted into the shoe, with the platform and the slider immobilized.
- Such device ensures a fastening that is the same every time, and prevents the problem of loosening and untying of conventional knots.
- the use of the device which comprises sliders and levers, is complex and increases the risks of breakage associated with such components.
- the components of the device are inaccessible and do not allow, for example, substitution of a damaged shoelace.
- US patent no. 2007/0209234 Al contains the teachings for providing a facilitated fastening device.
- Such device comprises a U-shaped foil, connected with the base, in a downward region, to a removable insole and, in an upward region, to the two opposite edges of the upper opening of the upper.
- the fastening takes place when, by virtue of the insertion of the foot into it, the foil is lowered to an anchoring position.
- the aim of the present invention is to provide a fastening device for a shoe which is capable of improving the known art in one or more of the above mentioned aspects.
- an object of the invention is to provide a fastening device for a shoe that is easy to use and does not require the hands to be used.
- Another object of the invention is to provide a fastening device for a shoe that allows substitution of the shoelace.
- Another object of the invention is to provide a fastening device for a shoe with a system for automatic engagement and disengagement.

- a drawstring 816 is affixed, at the ends, to the flaps 834a and 834b of a front portion of the quarter 815 which is directed respectively toward the outer and inner side portion of the foot.
- the drawstring 816 is affixed, at the ends, to the flaps 834a and 834b, for example, by way of stitching.
- the drawstring 816 may be knotted to specific eyelets or d-rings.
- the ends of the drawstring 816 may be joined together to form a closed path.
- the drawstring 816 passes through a plurality of first openings 853 and second openings 854, and also a plurality of third openings 863 and fourth openings 864.
- the second openings 854 and the fourth openings 864 are arranged at the front portion of the quarter 815.
- the first openings 853 and the third openings 863 are arranged on the single side wall 817 of the upper assembly, proximate to the sole.
- the drawstring 816 exits from the third opening 863 and enters the first opening 853. Furthermore, the drawstring 816 exits from the second opening 854 and enters the fourth opening 864, thus describing a loop 818, turning about a portion thereof, which is different from the one described by the loop 818. In other words, the drawstring 816 describes, from the flap 834a to the flap 834b, a path that is concatenated with itself.
- the ends of the drawstring 816 may be joined together to form a closed path, concatenated with itself.
- the drawstring 816 passes through the binding points, not shown in the figures, which are arranged on the appendages of the lever, which are also not shown in the figures.
- the plurality of first openings 853 is equal in number to the plurality of third openings 863.
- the plurality of second openings 854 is equal in number to the plurality of fourth openings 864.
- drawstring 816 is advantageously crossed between the two pluralities of second openings 854 and fourth openings 864.
- Adjustment of the tension of the fastening may be done by acting on the ends of the drawstring 816 which is fixed at the ends to the flaps 834a and 834b.
- Adjustment of the drawstring 816 occurs on the basis of the length of the portion of drawstring 816 that is left free to be concatenated with itself.
- the drawstring 816 is advantageously elastic: this to adjust the tension of the fastening if the ends of the drawstring 816 are joined together to form a closed path.
- the plurality of first openings 853 and of third openings 863 is smaller in number than the plurality of second openings 854 and of fourth openings 864. This to decrease the number of passages that the drawstring 816 performs below the lever. This is advantageous since, in moving closer to the fulcrum, the contribution to the operation of the device 810 decreases considerably, until it becomes negligible.
- the lever stroke needed to actuate the device 810 decreases drastically, making it preferable to decrease the number of passages of the drawstring 816, which is equal to the number of first openings 853 or of third openings 863, in order to simplify the device 810.
- a fastening device for a shoe which comprises an upper assembly, with an insole, and a sole
- the device being characterized in that it comprises: at least one drawstring, a lever, inside the upper assembly and positioned under the foot of the user, at least one binding point, on the lever, for the passage and/or the deviation of the at least one drawstring, means for automatic engagement and disengagement between the lever and the insole.
