DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a fastening device particularly for sports shoes.
Conventional shoes, used for example for trekking or for climbing on rock or ice, comprise a shell or an upper which have two flaps or a tongue that must be fastened usually by means of laces or of a cable.
These tensioning elements are usually guided at adapted adjacent hooks or rings which are associated proximate to the edges of the flaps, so as to allow the cable or laces to pass several times transversely to the upper or shell.
The ends of the lace or cable are then fastened, for example by forming a knot or in any case by being taken up with an adapted conventional lever.
The use of these guiding elements, which are constituted, as mentioned, by hooks or rings, has some drawbacks: due to the considerable friction that is produced by the multiple passages of the lace transversely to the upper or shell, the application of tension to the ends of the lace does not allow optimum tensioning of all the parts of the lace.
This forces the user to pull, in each instance, the various portions of the lace which are arranged transversely to the upper before fastening the loose ends.
This method has drawbacks, as the operation must be performed at very low temperatures that make the lace stiff or in any case force the operator to use gloves which make the operation even more troublesome.
SUMMARY OF THE INVENTION
The aim of the present invention is to solve the described technical problems, eliminating the drawbacks of prior art by providing a device that allows to achieve optimum and easy fastening of laces or cables in shoes which comprise an upper or a shell which has two flaps or a tongue to be fastened.
Within the scope of this aim, an important object is to provide a device that allows to achieve this fastening even at very low temperatures or if the user is wearing gloves.
Another important object is to provide a device in which fastening can be achieved by the user merely by gripping the ends of the laces or of the cable or an adapted lever with which said ends are associated.
Another object is to provide a device which is structurally simple and has low manufacturing costs.
This aim, these objects, and others which will become apparent hereinafter are achieved by a fastening device particularly for sports shoes comprising an upper or a shell that have two flaps or a tongue to be fastened by means of laces or cables, characterized in that it comprises multiple pulley members which are associated with said upper or shell and guide said laces or cables.
