Definitions

  • the present invention relates to a lever, particularly usable for sports footgear and particularly for ski boots.
  • lever for ski boots are currently known. This same Applicant filed, on July 17, 1975, an Italian patent, granted as no. 1039897, which discloses a lever constituted by an arm which is pivoted at one end to a pair of shoulders which are rigidly coupled to a flap of the boot; the arm has a toothed region for interaction with the end of a hook which can be associated, at its other end, with the other flap of the boot to be closed.
  • This known type of lever requires a surface finish of good aesthetic quality, because it is visible on the boot. Accordingly, materials, such as aluminum or plastics must be used which have a pleasant external appearance for the skier but at the same time do not have high mechanical characteristics, which are required in order to withstand the stresses and shocks to which they are subject during sports practice.
  • the protrusion of the levers on the lateral surface of the boot does not give said boot a neat aesthetic appearance, and said levers are subject to accidental opening or breakage in case of impact with the snow.
  • Italian utility model no. 185645 filed on January 20, 1981 discloses a lever closure, particularly for motorcycle boots, wherein the arm of the lever, which is again pivoted, at one end, at an adapted support which is rigidly coupled to a flap, is inserted within adapted notches defined on another flap to be closed.
  • this lever despite having a low number of components, has some problems, such as the direct interaction of the lever arm with the flap to be closed, which entails breakages or deformations due to the different strength of the materials in mutual contact.
  • a French patent, published as no. 2432280 and filed on August 3, 1978, discloses a closure device which is again composed of a U-shaped lever arm whose wings are again pivoted, at their ends, at an adapted support which is rigidly coupled to a flap.
  • a pin is interposed between the wings and interacts with an adapted rack which protrudes from the other flap to be joined.
  • This device has problems, because the engagement between the lever arm and the rack is not always reliable.
  • the rack must be made of plastic material together with the boot flap and therefore does not withstand the high stresses imparted while skiing.
  • this device too comprises a large number of components and protrudes beyond the contour of the boot; the closure device also has a considerable longitudinal size which affects a very wide area of the boot.
  • One aim of the present invention is to eliminate the problems described above in known types, by providing a lever which is optimally associable with a flap of a boot and allows to ensure an optimum adjustment of the mutual securing of two flaps to be joined although it does not, at the same time, protrude from the outer contour of the boot.
  • an object of the invention is to provide a lever which is structurally simple and can be produced with a low number of components.
  • Another object is to provide a lever which can be easily interchanged even by the user himself, without requiring particular tools.
  • Another object is to provide a lever having a small size and thus occupying a minimal surface of the boot.
  • Another object is to provide a lever which is reliable and safe in use.
  • a securing lever particularly for sports footgear comprising a main body and at least one flap which can be closed onto said main body, characterized in that said at least one flap has at least one wing which can be removably associated with a containment element for at least one lever arm which has means for temporary coupling with engagement means associated with said main body.
  • the securing lever is particularly usable for sports footgear, such as a ski boot, which comprises at least one flap 2 which can be closed onto a main body of the footgear, such as an upper or a quarter or a shell, generally designated by the reference numeral 3.
  • At least one wing 4 is provided at said at least one flap 2 and, in the particular embodiment shown in figure 3, is substantially C-shaped.
  • a means for temporary connection to a containment element, constituted by a shell 6, is provided on the tabs 5a and 5b of the wing 4, which are directed toward the main body.
  • the means is constituted by a plurality of lugs 7a and 7b which protrude transversely to the respective tabs 5a and 5b, have a preferably cylindrical transverse cross-section and protrude outside the tabs 5a and 5b.
  • the ends of the lugs 7a and 7b which do not face each other are chamfered along an inclined plane.
  • the tabs 5a and 5b can be moved mutually closer in an elastic manner and can be inserted within an adapted cavity 8 defined axially inside the shell 6.
  • the cavity 8 is connected, at both sides, with adapted first seats 9a and 9b which are shaped complementarily to said lugs 7a and 7b and to second seats 10a and 10b which are shaped complementarily to the remaining parts of the tabs 5a and 5b which can be positioned within the shell 6.
  • the lugs 7a and 7b enter the respective first seats 9a and 9b and the remaining parts of the tabs 5a and 5b arrange themselves at the second seats 10a and 10b: the shell 6 is thus temporarily rigidly coupled to the flap 2.
  • At least one lever arm 11 is insertable at the cavity after the placement of the wing 4.
  • the lever arm in fact has a pair of coupling elements 12 which can be slidingly arranged at the cavity 8 and are connected to a block 13 whose free end is substantially C-shaped and comprises a temporary engagement means, such as a transversely arranged pin 14, suitable to interact with an engagement means such as a rack 15 which is associated with said upper and/or said quarter and/or said shell 3.
  • the axial movement of the block 13 with respect to the shell 6 is allowed by virtue of the presence of a threaded stem 16 which protrudes axially with respect to the block 13 and interacts with a complementarily threaded and externally knurled pawl 17 which can be activated by the user and can be arranged at the adapted opening 18 defined on the shell 6.
  • the pawl also has the task of retaining the lever arm 11 inside the shell 6.
  • the lever arm 11 is then inserted, placing the pair of coupling elements 12 thereof within the cavity 8 and inserting the pawl 17 in the opening 18, screwing it onto the threaded stem 16.
  • the user may of course operate the pawl 17 to increase or decrease the degree of securing, as shown in figures 7 and 8.
  • a lever having been provided which is rapidly and optimally associable with a flap of a boot and allows to ensure an optimum adjustment of the mutual securing of said flap and of the upper and/or a quarter and/or the shell.
  • lever is contained within the flap to be secured, so that it does not protrude from the outer contour of the boot, thus improving the aesthetic characteristics thereof.
  • the lever is constituted by a low number of components, and this allows to reduce the manufacturing costs.
  • figure 9 illustrates a second embodiment, wherein a securing lever comprises at least one flap 102 which has a substantially C-shaped wing 104.
  • a securing lever comprises at least one flap 102 which has a substantially C-shaped wing 104.
  • cylindrical lugs 107a and 107b are transversely associated with the free ends of the tabs 105a and 105b of said wing.
  • Tabs 105a and 105b can be compressed elastically so that they are temporarily accommodated at first seats 109 and second seats 110 formed laterally with respect to a cavity formed axially to a shell 106.
  • the securing lever comprises a lever arm 111 having a pair of coupling elements 112 which can be slidingly positioned at the cavity 108 and are connected to a block 113 which has, at one end, a pin 114 which interacts with the adapted rack.
  • the lever arm 111 can be adjusted by means of an adapted pawl 117 which interacts with a threaded stem 116 which protrudes axially with respect to the block 113.
  • the pawl can be operated by the skier through an adapted opening 118 formed on the shell 106.
  • a third embodiment of the invention is illustrated in figures 10 and 11, wherein the flap 202 has at least one wing 204 on which adapted engagement means, such as a plurality of first holes 220a and 220b formed laterally with respect to a longitudinal through slot 221, are provided.
  • adapted engagement means such as a plurality of first holes 220a and 220b formed laterally with respect to a longitudinal through slot 221, are provided.
  • the lever also comprises a shell 206 which is constituted by two half-bodies 222a and 222b which can be mutually coupled.
  • the first half-body has a plurality of protrusions 223a and 223b which constitute means for gripping said first holes and second holes 224a and 224b formed on the second half-body 222b.
  • the removable connection between the wing 204 and the shell 206 thus occurs by opening the two half-bodies 222a and 222b, arranging the first holes 220a and 220b at the protrusions 223a and 223b and then closing the half-bodies 222a and 222b on one another.
  • a lever arm 211 can be arranged beforehand between the wing 204 and the half-body 222a.
  • the lever arm has a block 213 provided with a pin 214 which can be associated at the adapted rack 215 which can be coupled to the upper and/or to the quarter and/or to the shell 203.
  • the lever arm 211 also has means suitable to adjust its longitudinal extension, such as an externally knurled pawl 217 which has a threaded seat for a complementarily threaded stem 216 which is associable at the pair of coupling elements 212 of said lever arm 211.
  • Openings 219a and 219b are furthermore provided on the first half-body and on the second half-body.
  • the lever can also be applied at sports footgear such as roller skates, ice skates, snowboard boots, trekking and mountain footgear, motorcycle boots, etc.
