Abstract
Description
- The present invention relates to a fastening lever, particularly for sports shoes.
- Conventional ski boots have a first flap to be joined to a second flap by means of levers comprising a lever arm, which can be gripped by the user, and engages a toothed strap associated with the other flap to be joined.
- Those conventional fastening levers have the drawback that the toothed strap is made of plastics and must be at the same time very rigid and non-deformable, proximate to the interaction with the lever arm, and very flexible and adaptable to the radius of curvature of the region where it rests, for example on the shell or on the quarter.
- Those two features are incompatible, also because the above mentioned radius of curvature is always variable according to the size of the boot and to the degree of fastening to be achieved with the lever.
- As a partial solution to the above drawback, it is known to provide toothed bands by using rather flexible plastics, but this penalizes the retention ability of the teeth.
- In order to compensate for this limited retention of the teeth of the band, it is known to use selectively wide straps. However, even this entails a drawback, since it becomes necessary to use wide lever arms which accordingly have dimensions which penalize the styling of the boot, especially in medium to small sizes, in addition to increasing its production costs.
- The aim of the present invention is to solve the above cited drawbacks, by providing a fastening lever which uses a toothed strap which allows to achieve optimum fastening of the flaps of a sports shoe while obtaining optimum characteristics of adaptability to the radius of curvature of the region in which the lever is applied as well as high rigidity of the teeth of the strap, so as to achieve optimum fastening.
- A further object of the invention is to provide a compact fastening lever.
- A further object is to provide a fastening lever which has a low weight.
- A further object is to provide a fastening lever which is reliable and safe and free from malfunctions.
- This aim and these and other objects which will become better apparent from the description that follows are achieved by a fastening lever, particularly for sports shoes, comprising at least a first flap to be fastened to a second flap, said lever comprising a lever arm articulated to shoulders associated with a plate rigidly coupled to one of either said first or second flaps, said lever arm selectively interacting with a first end of a toothed strap; characterized in that said toothed strap has a second end comprising a pulley member engaging a traction member having two ends associated with the other one of said first or second flaps to be fastened.
- Other objects will become better apparent during the description that follows, which must be considered together with the accompanying drawings, which illustrate by way of non-limitative example a particular embodiment and wherein:
- Figure 1 is a right hand side view of a ski boot provided with the fastening lever according to the invention;
- Figure 2 is a left hand side view of the ski boot of Fig. 1;
- Figure 3 is a front view of the ski boot of Figs. 1 and 2;
- Figure 4 is a perspective view of the fastening lever according to the invention;
- Figure 5 is a cross section view of the ski boot provided with the lever according to the invention.
-
- With reference to the above cited figures, the numeral 1 designates a sports shoe, particularly a ski boot, having a
shell portion 2 and aquarter portion 3. - The
shell 2 and thequarter 3 have afirst flap 4 to be joined to asecond flap 5 by means of one or more fastening levers, designated by thereference numeral 6. Thefastening lever 6 comprises aplate 7 associated with thefirst flap 4, for example by means of a first rivet 8. - Two shoulders 9 protrude from the
plate 7, and alever arm 11 is articulated to the shoulders 9 by means of apivot 10. The lever arm selectively interacts with thefirst end 12 of atoothed strap 13. - The band is made of substantially rigid plastics, and this allows to obtain
teeth 14 which are compact and at the same time ensure optimum locking with thelever arm 11. - A
traction member 18, constituted by a cable, is slidingly pivoted at thesecond end 15 of thetoothed band 13 which is directed toward thesecond flap 5, at a pulley member, or cable guide, 16 which is associated with thesecond end 15.Guide 13 may be integral with thesecond end 15 or fastened thereof by means of asecond rivet 17. - The traction member is constituted by a very flexible cable or string whose
ends 19a and 19b are coupled at two separate points of thesecond flap 5 by means ofterminals 20 for anchoring to the second flap by means ofthird rivets 21. - This allows to place the
ends 19a and 19b in regions which are spaced apart and the flexible cable adapts perfectly in any case to the curved supporting surfaces on the shell and on the quarter. - Since the toothed band is made of very rigid plastics with teeth which are highly resistant to traction, it may be considerably narrower than the conventional toothed straps of the prior art therefore allowing to produce
smaller levers 6, so as to improve the styling especially of shoes of smaller sizes. - The presence of the two
terminals 20 also allows to use levers which double the traction points at thesecond flap 5. - The use of the
cable guide 16, which acts as a pulley, allows to achieve perfect balancing between the traction applied to the toothed band and to the terminals by means of the flexible cable. This balancing of all the closure points allows the sports shoe to adapt anatomically to the shape of the foot. - The aesthetic appearance of the assembly gives the sports shoe a styling which is more similar to that obtainable with a lace-type closure and a trekking boot than to the typical styling of a ski boot.
- The materials and the shape or dimensions of the individual components of the shoes may vary according to specific requirements.
