Definitions

  • the present invention refers to a fastening device, in particular for sports footwear such as ski boots, mountaineering boots, skating boots, and the like.
  • Fastening devices such as generally known and currently used in the art include the so-called binding or fastening buckles comprising a lever arm, which is attached to the footwear on one of the edges thereof to be fastened, and to which there is associated, by means of a so-called wire or link-up rod, a hook-up member adapted to engage a rack attached to the other one of the footwear edges to be bound together.
  • the link-up rod is formed by two members that are telescopically coupled with each other by means of a screw/nut screw system and enable the length of the same link-up rod to be adjusted micrometrically, i.e. finely, so as to in this way enable the tightening tension to be varied.
  • a drawback that is typically encountered in prior-art solutions lies in the fact that, owing to the clearances existing between the various parts making up the fastening device, as well as the weight of each such part, the link-up rod and the hook-up member fail to be kept into due alignment with the rack when the fastening device is unfastened, i.e. in a condition in which the hook-up member is not engaging the rack.
  • This drawback is particularly felt with those fastening devices that are adapted to tighten the footwear around the lower portion of the leg, and are therefore positioned on the upper of for instance the boot or the skate.
  • the force of gravity due to the inherent weight of the component parts is oriented downwards, roughly in a direction perpendicular to the direction of mutual alignment thereof, thereby exerting a torque on the link-up rod that causes the telescopic member supporting the hook-up member to rotate relative to the other telescopic member connected to the lever arm.
  • a torque causes the hook-up member to swing downwards, so that it becomes misaligned relative to the rack it is due to engage.
  • This operation requires both hands to be practically used at the same time, considering that a hand must be used to keep said hook-up member engaged in the selected catch, while the other hand is used to complete the tightening of the lever, so that it proves particularly inconvenient to perform under certain environmental conditions of use of the sports footwear: in the case of ski boots, for example, the footwear is used under low-temperature conditions and, sometimes, in the presence of ice forming on the fastening device, while the user generally wears gloves that restrict the sensitivity and motility of the hands.
  • an important purpose of the present invention is to provide a fastening device of the above-indicated kind, which is capable of keeping the link-up rod, the hook-up member and the rack duly aligned with each other not only under mutual engagement conditions, but also when they are unfastened, i.e. disengaged from each other.
  • Another purpose of the present invention is to provide a fastening device of the above-cited kind, in which the selected micrometric adjustment for a desired length of the link-up rod is capable of being maintained in a stable manner over time, without any need arising for the user to subsequently perform any further re-adjustment or correction.
  • a further purpose of the present invention is to provide a fastening device of the above-cited kind, in which the micrometric or fine adjustment of the length of the link-up rod is capable of being performed in such a manner as to be immediately perceived by the user.
  • the reference numeral 1 is used there to generally indicate a fastening device comprising an lever arm 2 that is pivotally hinged, in correspondence to a first cross-wise axis 3, on to a base (not shown) adapted to be attached to one of the edges of a sports footwear to be fastened, i.e. tightened together.
  • a link-up rod 4 is pivotally hinged with an end thereof on said lever arm 2 along a second cross-wise axis 5 by means of a first pin 6 passing through the lever arm and the link-up rod in correspondence to respective holes 7 (not visible in the Figures) provided both in the link-up rod and the lever arm.
  • the link-up rod 4 is coupled to a hook-up member 8, preferably by means of a second pin 9, so as to allow for just a limited extent of swinging movement of the hook-up member 8 relative to the link-up rod 8 about a third cross-wise axis 10.
  • the hook-up member 8 is provided with known hook-up means, such as for instance a crosspiece, tongue, pawl or the like, adapted to engage into a desired one of the catches of a rack (not shown) that is capable of being attached on the other edge portion of the footwear to the purpose of enabling the same footwear to be tightened and fastened.
  • known hook-up means such as for instance a crosspiece, tongue, pawl or the like, adapted to engage into a desired one of the catches of a rack (not shown) that is capable of being attached on the other edge portion of the footwear to the purpose of enabling the same footwear to be tightened and fastened.
  • the link-up rod 4 comprises a first tensioning element 11, provided at an end portion thereof with an externally threaded head 12 and, at the other end portion thereof, with a head 13 adapted to couple up with the hook-up member 8 in the manner described hereinbefore, and a second tensioning element 14 provided with a longitudinal, internally threaded dead hole 15;
  • Figure 3 is a cross-sectional view of this second tensioning element 14, as viewed along the plane III-III of Figure 4, in which the above-cited hole 15 is clearly shown.
  • the threaded head 12 of the first tensioning element 11, which forms the screw, is thus adapted to engage said internally threaded dead hole 15 of the second tensioning element 14, which therefore performs as the screw nut, in such a manner as to enable the micrometric adjustment of the total length of the link-up rod 4 to be carried out through the telescopic displacement of the first tensioning element 11 relative to the second tensioning element 14.
  • a peculiar feature of the fastening device lies in the fact that, between the first tensioning element 11 and the second tensioning element 14, and in particular between the threaded head 12 and the bottom of the threaded dead hole 15, there is arranged at least an elastically deformable member 16, such as for instance a spring, which exerts a compressive action upon the first tensioning element 11, in correspondence to the threaded head 12, which is aimed at opposing the torque being applied on said head by the force of gravity acting on the hook-up member 8.
  • an elastically deformable member 16 such as for instance a spring
  • the hook-up member 8 is prevented from lowering due to the rotation of the first tensioning element 11 relative to the second tensioning element 14, and these same component parts are in turn prevented in this way from displacing into misalignment with respect to the rack, when the tension imparted by the elastically deformable member 16 upon the first and the second tensioning element 11 and 14, in correspondence of the respective threads thereof, is greater than the torque generated by the force of gravity, which the hook-up member 8 is subject to when not engaging the hook-up rack, thereby ensuring a substantial alignment of the link-up rod with the hook-up member under all conditions.
  • a slide 17 that is slidably housed in the threaded hole 15 of the second sensor 14 and is provided axially with an aperture 18.
  • the end portion of the head 12 that interacts with the corresponding end portion 19 of the slide 17 is provided with an indentation-like recess 21 featuring two faces that are counter-shaped to the respective faces of the end portion 19 and inclined substantially according to the same angle.
  • the first pin 6 performing as the fulcrum between the lever arm 2 and the link-up rod 4 is arranged to pass through the holes 7 of the second tensioning element 14 and the aperture 18; in this way, the slide 17 is not caused to rotate by the threaded head 12 of the first tensioning element 11 when the latter is rotated in view of performing the desired micrometric adjustment of the length of the link-up rod 4.
  • the two faces of the indentation-like recess 21 cause the slide 17, the rotation of which is prevented by the first pin 6, to perform a translational motion in the same direction in contrast with the action exerted by the elastically deformable member 16, whereas during the remaining part of the rotation, from 90° to 180°, the elastically deformable member 16 presses again the end portion 19 of the slide 17 into engaging the matching, complementarily shaped faces of the threaded head 12, thereby bringing the slide 17 and the head 12 into a new stable position of mutual engagement, while at the same time producing a snap-like effect that is perceived by the user both on a tactile and auditory level.
  • a further 180°-rotation in the same direction will cause the head 12, and the slide 17, to further move on towards the bottom of the threaded dead hole 15, thereby reducing the total length of the link-up rod 4.
  • Figures 7 and 8 illustrate the condition of minimum total length of the link-up rod 4 in the stable position thereof, in which the head 12 and the slide 17 are mutually engaged, and in the state in which the first tensioning element 11 is rotated to length adjustment purposes, respectively.
  • this fastening device is capable of maintaining the link-up rod, the hook-up member and the rack properly aligned with each other not only in the condition in which said hook-up member engages the rack, but also in the unfastened condition of the device, thanks to both the tension generated by the elastically deformable member 16 between the first and the second tensioning element 11 and 14, and the effect of the end portion 19 of the slide 17 firmly engaging with its inclined planar faces the corresponding, complementarily shaped faces of the indentation-like recess 21 of the threaded head 12.
  • the effect of the above-cited tension as enhanced by the respective inclined faces of said matching parts being so firmly engaged with each other, enables the force of gravity acting of the fastening device, when the latter is unfastened, to be effectively opposed.
  • the fastening device is capable of ensuring that the micrometric adjustment of the length of link-up rod selected by the user will be kept unaltered over time, without any subsequent re-adjustment being required any more, thanks to the rotation prevention effect brought about by the end portion 19 of the slide 17 being firmly engaged in the corresponding recess 21 of the threaded head 12.
  • a further advantage of the fastening device according to the present invention derives from the fact that the micrometric, i.e. fine adjustment of the tie-rod length is performed in a stable manner and is immediately perceived by the user owing to the end portion 19 snapping into engagement with the corresponding recess 21.
  • Figure 9 can be noticed to illustrate a link-up rod 104 comprising a first tensioning element 111 and a second tensioning element 114 that are substantially similar to the afore described ones, as well as at least an elastically deformable member 116 extending in the direction of the threaded head 112 of the first tensioning element to form a kind of buckle consisting of two axial arms 117a and 117b connected with each other by a crosspiece 119; therefore, this buckle acts as the slide 117, which is thus formed integrally with the elastically deformable member 116 as a single-piece construction, and the crosspiece 119 of which is adapted to move into engaging the indentation-like recess 121 of the head 112, when in a stable position, and is compressed by this head, in opposition to the elastically deformable member 116, when it is rotated for micrometric adjustment.
  • Figure 10 illustrates a further embodiment of a link-up rod 204 for the fastening device according to the present invention. While this embodiment is substantially identical to the one that has been described hereinbefore with reference to Figures 1 to 7, it differs therefrom for the fact that the recess 221 in the head 212 is given a polyhedral conformation, in such a manner that a stable engagement thereof with the inclined planar faces of the end portion 219 of slide 217 occurs every 90° of rotation, instead of every 180° as in the other case.
