Abstract
A fastening device particularly usable in sports shoes (1) includes a band (7), a first fixed end (8)
of which is associated with a ring (10) that cooperates with the second movable end (9) of the
band in order to guide it. A first means (14) is rotatably associated with the ring, which acts as
a guide for the second movable end of the band, and is adapted to limit the friction
between the band and the ring. There is also a second (15) means for increasing friction with
the band.
Description
- The present invention relates to a fastening device particularly for sports shoes, such as for example ski boots.
- It is known to manufacture ski boots that have a first flap and a second flap to be fastened at the shell and at the quarter articulated thereto.
- The flaps are fastened together by levers arranged transversely to the shell and/or the quarter so as to fasten the shoe around the metatarsal region of the foot and/or the lower part of the leg of the user.
- In combination with the use of these levers, it is also known to use at least one fastening band that is transversely associated with the quarter, preferably at a region thereof that is arranged at the level of the tibia.
- Such band, usually made of plastics, is provided with a grip means of the type commonly known by the trademark "Velcro", which provides a coupling produced by overlapping.
- Such band is therefore arranged around the quarter so as to have a first fixed end and a second movable end that can be mutually connected by means of a metallic ring, which is usually made of steel and has an approximately rectangular plan shape.
- In greater detail, the first fixed end of the band is associated with one side of the metal ring, while the second movable end of the band is inserted at the opposite side thereof.
- In this manner, the metallic ring allows to guide the second movable end, which can therefore be pulled by the user toward the region arranged opposite the first fixed end of the band.
- The guiding of the second end of the band on the ring allows to tension the band as a consequence of the sliding of a portion thereof at the respective side of the metallic ring.
- Once the intended fastening has been achieved, the band is locked by overlapping the second movable end on a respective adjacent portion of the band, so as to allow their coupling.
- A first drawback that is observed in such conventional type of fastening band is the fact that the activation of the bands is very troublesome for the user, because the sliding with respect to the metallic ring is greatly hindered by the friction that occurs between the parts arranged in mutual contact.
- A further drawback is that the locking of the band is often inaccurate, because unexpected slippages can occur between the band and the metallic ring.
- A further important drawback is that the band can deteriorate and wear rapidly due to the friction that hinders the sliding of the band with respect to the metallic ring.
- The aim of the present invention is therefore to solve the drawbacks noted above and therefore solve the described technical problems by providing a fastening device that can be used easily and at the same time allows to achieve precise closure of the shoe around the respective region of the foot or of the lower part of the leg.
- An object is to provide a fastening device that allows to perform rapidly and safely the guiding and subsequent locking of a band.
- A further object is to provide a fastening device that is reliable over time and is not subject to deterioration or rapid wear.
- A further object is to provide a device that is structurally simple and has low manufacturing costs.
- This aim, these objects and others that will become better apparent from the description that follows are achieved by a fastening device, as claimed in the appended claims.
- Other objects will become better apparent in the description that follows, which must be considered together with the accompanying drawings, which illustrate only by way of non-limitative example a particular embodiment, which is illustrated by way of non-limitative example in the accompanying drawings, wherein:
- Figures 1 to 3 are side views of a sports shoe provided with a fastening device according to the invention;
- Figure 4 is a front view of the fastening device according to the preceding figures;
- Figure 5 is a sectional view of the fastening device, taken along the line V-V of Figure 4;
- Figure 6 is a sectional view of the guiding ring, taken along a longitudinal plane;
- Figure 7 is a sectional view of the guiding ring, taken along the line VII-VII of Figure 6;
- Figure 8 is a bottom view of the guiding ring according to the preceding figures;
- Figure 9 is a view of a detail of Figure 6.
-
- With reference to the cited figures, and bearing in mind that they exemplify a particular embodiment and are in variable scale and that individual reference numerals designate identical or equivalent parts therein, the reference numeral 1 designates a sports shoe, such as for example a ski boot, which includes a
shell 2 to which aquarter 3 is pivoted approximately at the malleolar region. - The
shell 2 and thequarter 3 have afirst flap 4 and a second flap, not shown, which can be mutually connected for example by partial overlap in the metatarsal and instep region. - The fastening of the
first flap 4 and of the second flap around the foot and the lower part of the leg of the user is performed by activating levers, of a per se known type, each designated by thereference numeral 5, and a fastening device according to the invention, generally designated by thereference numeral 6. - The device includes a
band 7, made for example of plastics, which has a first male layer at one surface and a second female layer at the opposite surface, both of the type commonly known by the trademark "Velcro", so that they can be mutually coupled by overlapping. - The
band 7 is arranged transversely to thequarter 3, so as to surround the quarter, for example at the region of the tibia, and has a first fixed end, designated by thereference numeral 8, and a second movable end, designated by thereference numeral 9. - The first fixed
end 8 of theband 7 is rigidly coupled to thefirst flap 5 and at the same time is associated with aring 10 which is preferably metallic and is allowed to cooperate with the secondmovable end 9, so as to allow its guiding. - In greater detail, the
ring 10 has a preferably rectangular shape and is constituted by a pair of spacer shoulders or linkages, generally designated by thereference numeral 11, that are mutually parallel. Afirst pivot 12 and asecond pivot 13 are associated transversely, for example by riveting with the ends of theshoulders 11. The pivots are arranged at a preset distance from each other and approximately at right angles to the spacer shoulders orlinkages 11. - The first fixed
end 8 of theband 7 is associated with thefirst pivot 12, and a first means for limiting the friction between theband 7 and thering 10 is rotatably associated with thesecond pivot 13; the means is preferably constituted by aroller 14, which is arranged coaxially with respect to thesecond pivot 13 so as to be freely pivoted with respect to the pivot. - The
roller 14 has a circular annular transverse cross-section and an approximately I-shaped longitudinal cross-section. - The
roller 14 is provided with a second means, suitable to increase the friction with theband 7, which is preferably constituted by a plurality ofprotrusions 15 which protrude radially and longitudinally with respect to theouter surface 16 of theroller 14. - Figures 1 to 3 show how it is possible to insert manually the second
movable end 9 through the gap between thefirst pivot 12 and theroller 14, so as to allow, by pulling manually thesecond end 9, the subsequent guiding of the end toward the region directed away from the first fixedend 8. - Pulling the second
movable end 9 toward the region directed opposite with respect to the first fixedend 8 causes an equal sliding of theband 7 with respect to thesecond pivot 13, so as to achieve the intended fastening between thefirst flap 4 and the second flap of thequarter 3 due to the tensioning thus received by theband 7. - The sliding of the
band 7 with respect to thesecond pivot 13 is matched by an equal rotation of theroller 14 about thepivot 13. - This is due to the fact that the
protrusions 15 of theroller 14 perform an antislip action for the respective portion of theband 7 that is temporarily rested at theouter surface 16 of theroller 14, consequently entraining it in rotation. - The rotation of the
roller 14 about thesecond pivot 13 occurs easily, since the friction produced between the parts arranged instantaneously in contact is very small, for example by applying lubricants or by using suitable materials. - Respective first annular ridges, designated by the
reference numeral 17, protrude radially at the ends of theouter surface 16 of theroller 14, and contain and guide theband 7 during its sliding with respect to thesecond pivot 13. - Second
annular ridges 18 protrude axially at the ends of theouter surface 16 of theroller 14, preferably in a region adjacent to the lateral surface of thesecond pivot 13, and are arranged approximately at right angles to thefirst ridges 17. - The function of the second
annular ridges 18 is to reduce the friction of theroller 14 also in relation to the facing surfaces of the spacer shoulders orlinkages 11. - Once the intended fastening between the
first flap 4 and the second flap is achieved, by overlapping the secondmovable end 9 on a respective adjacent portion of theband 7 it is possible to produce the coupling between the female layer and the male layer thereof, so as to provide the temporary locking of theband 7. - It has thus been shown that the described solution has achieved the intended aim and objects, a fastening device having been provided which allows to obtain easily a precise closure of the corresponding region of the shoe, because the application of the roller at the second pivot drastically reduces the friction between the band and the ring and at the same time prevents the sliding and slipping of the band with respect to the ring once the intended mutual fastening of the first and second flaps has been achieved.
- The roller also allows to avoid or at least reduce drastically the wear of the band, both by way of the drastic reduction of the friction that occurs between the band and the ring and because the diametrical dimension of the roller gives the band a larger contact surface.
- The materials and the shape or the dimensions of the individual components of the described embodiment may of course vary according to specific requirements.
- The various means for performing certain different functions need not certainly coexist only in the illustrated embodiment but can be present per se in many embodiments, including ones that are not illustrated.
- Anything found to be already known during the patenting process is understood not to be claimed and to be the possible subject of a disclaimer.
