Definitions

  • the present invention relates to a ski boot.
  • a structure of a ski boot comprising a shell and a front quarter, provided monolithically, having a transverse slot on said front quarter at the region of the foot instep.
  • French patent application no. 8008948 is also known, wherein a rear-entry ski boot is described which is provided, on the front quarter and at the region of the foot instep, with a groove arranged transverse with respect to the quarter.
  • the flexibility of the front quarter is allowed since the same can move forwards until it closes the span of said groove and thus causes the abutment of the two facing edges thereof.
  • a small rigid block, slideable in said groove is provided therein, said block being lockable in the desired point interposed between the end and the middle portion of said groove.
  • the quarter can thus perform a forward motion until its end makes contact with said raised portion.
  • sliders are associable, at said slot and at the interspace between the end of said quarter and said raised portion provided on the shell, said sliders being variably positionable therein.
  • the main aim of the present invention is therefore to eliminate all of the disadvantages of the prior art, in particular those described above, by devising a ski boot which allows to obtain a gradual forward flexibility of the quarter, without the latter necessarily rotating with respect to the shell, such flexibility being achieved progressively according to the stress imparted by the skier.
  • an important object of the invention is to devise a ski boot wherein the flexibility of the front quarter thereof is a function of easily controllable parameters.
  • Another object of the invention is to provide a ski boot wherein it is easy to preset and therefore to vary the characteristics of flexibility of the front quarter.
  • a further object of the invention is to devise a ski boot structurally simple and economical.
  • Still another object of the invention is to provide a ski boot obtainable in a simple manner from a constructive point of view.
  • Not least object of the invention is to devise a ski boot which allows to accommodate, at the malleolar region of the front quarter, any required adjustment or locking devices.
  • a rear entry ski boot comprising a shell, a rear quarter and a front quarter, said rear quarter being pivotally connected to said shell, characterized in that is comprises at least one band-like element and a plurality of slots, said band-like element being rigidly associated with said shell and interconnected to said front quarter, said plurality of slots being formed in said band-like element.
  • the ski boot comprises a sealing element against infiltrations of water at said slots.
  • slots are associable means for further graduating the flexibility of the front quarter.
  • the reference numeral 1 indicates a rear-entry ski boot which comprises a shell 2 provided with a flap 4 projecting from the foot instep region 3, above the shell 2 and embracing the tibial region 5 of the foot.
  • Said flap 4 is elastically deformable, it being provided, preferably but not necessarily, with a transverse opening 6 at the foot instep region 3, the flexing of the foot instep occurring in said region during use of the boot 1.
  • the opening 6 has a configuration adapted to impart a desired degree of elasticity to said flap.
  • an element for connecting to a front quarter 7 may be provided, consisting of a lug 8 projecting from said flap at the surface facing towards the tip of the boot.
  • Said lug 8 essentially consists of a parallelepipedal shaped member having, at the end facing the foot instep region 3, a small tooth 9 adapted to engage in snap-together engagement relationship the end 10 of a longitudinal notch 11 provided on said front quarter 7.
  • a sealing element for preventing the ingress of water consisting of a sealing element or gasket 12 encircling said flap and said shell at the foot instep region 3 and partially at the tibial region 5.
  • said gasket 12 is associated at one end 14a with said flap 4 by means of suitable studs 13, the other end thereof 14b, preferably being unattached and resting on said shell 2 proximate to a raised portion 15, adapted for the support and abutment of the perimetral edge or border 16 of a band-like element 17, adapted for interconnecting the front quarter 7 and the shell 2.
  • the band-like element 17 is matchingly shaped with respect to the region 3 of the foot instep, while the front quarter 7 is matchingly shaped with respect to the region 5 of the tibia.
  • the band-like element 17 has two lateral wings 17a, 17b associated, at their free end, with said shell 2 by means of a first stud 18 and a second stud 19.
  • the first stud 18 allows to fix the front portion of the band-like element 17 to the shell 2
  • the second stud simultaneously allows to fix the rear portion of the band-­like element 17 to the shell 2 and acts as a hinge point between the shell 2 and the rear quarter 20, the latter being thus able to rotate to allow the opening of the boot.
  • the band-like element 17 is provided with a plurality of slots, in the particular embodiment three slots are illustrated: thus, there is a first slot 21, a second slot 22 and a third slot 23, identical and arranged parallel to one another and to the raised portion 15 of the shell 2, their lateral ends partially affecting said lateral wings 17a, 17b of the band-­like element 17.
  • Each of the slots 21, 22 and 23 is a substantially parallel slot having a span 50 of constant dimensions.
  • the skier In flexing, the skier imparts a force to the front quarter 7 which makes it flex forwards: this flexing occurs and is allowed by virtue of the presence of the band-like element 17, and the slots 21, 22 and 23 formed therein.
  • the stress imparted to the quarter 7 is transmitted to the band-like element 17 and initially causes the span of the first slot 21 to diminish until the abutment of the facing edges thereof occurs; subsequently the span of the second slot 22 is reduced and closed, and once the span thereof has been closed the span of the third slot 23 is reduced and closed.
  • the foot instep region 3 whereat said slots 21, 22, 23 are provided on said band-like element 17 is planar or advantageously slightly convex with the concavity directed towards the exterior, i.e. in a direction extending away from said first stud 18 and said second stud 19.
  • Such an arrangement ensures correct operation of the band-like element 17, by preventing the portions thereof delimiting the slots 21, 22, 23 from overlapping, obtaining undesirable and uncontrollable effects in flexing.
  • the presence of the gasket 12 prevents any infiltration of water due to the presence of snow at the slots.
  • Fig. 10 illustrates the flexing condition if a force F1 is imparted to the front quarter 7 closing the spans of the first and second slots of the band-like element 17 according to the diagram of fig. 9 where the decrease of the span of each individual slot is plotted on the abscissa in sequence.
  • Means adapted to further graduate the flexibility of the band-like element 17 are associable with said slots 21, 22, 23, said means being composed of one or more blocks 24, essentially T-shaped, the stem 25 thereof has a width equal to the span of the slot, said block 24 also having a grip element 26, projecting therefrom to enable a skier to shift the block, to regulate the flexibility of the band-like element 17, as will be described hereinafter.
  • the fins 27 of the block 24 instead rest on the surfaces of the band-like element 17 adjacent to the slot and facing towards the interior of the boot, said fins 27 prevent the slippage of the block 24 out of the slot, and guide the block when moved along the slot.
  • At least one recessed seat 28, shaped complementarily with respect to the stem 25 of the block and therefore such as to allow its accommodation therein, may be provided at each slot.
  • the length of the fins 27 is such as to prevent the slippage of the block out of the slot even when the block is rendered inoperative.
  • the ski boot is furthermore obtainable in a simple manner from the point of view of manufacture, this allowing to contain its cost.
  • the front quarter 7 and the band-like element 17 can be formed monolithically or rigidly associated with each other.
  • the front quarter 107 which embraces the tibial region 5 of the leg can be rigidly associated with lateral extensions 107a (Fig. 5), pivotably associated with the second stud 119, while the band-like element 129, embracing the foot instep region, may be rigidly associated with the shell at the studs 118 and 119 as illustrated in fig. 15.
  • the band-like element 117 is rigidly associated with the shell, and the front quarter 107 is pivotally mounted to the band-like element.
  • the slots 121, 122 and 123 are provided in the band-like element 129.
  • the front quarter 107 can oscillate about the point, defined by the studs 119, whereat the lateral extensions 107a are pivotally connected to the band-like element 117. Free forward oscillatory movement of the front quarter 107 is delimited by abutment engagement of the front lower edge 107c of the front quarter with the rear upper edge 117c of the band-like element 117. Thereafter, any force or flexing of the front quarter 107 tends to close the slots 121, 122, 123 in the band-like element 117, which in turn acts on the shell.
  • the arrangement allows, for example, to preset the amount of flexibility of the boot by adopting the required band wherein, for example, the color features might suggest a given obtainable degree of flexibility to the skier.
  • Fig. 4 illustrates a second embodiment of the invention wherein a first slot 221, a second slot 222 and a third slot 223 are provided on the band-like element 217, all said slots being arranged at the foot instep region approximately parallel to the raised portion provided on the shell.
  • the ends of the second slot 222 affecting the lateral wings 217a of the band-like element 217, are again approximately parallel to said raised portion, the ends of the first and third slots 221, 223 being instead arranged so as to converge with respect to the second slot 222.
  • Fig. 5 illustrates a third embodiment, wherein a first slot 321, a second slot 322 and a third slot 323 are provided on the band-like element 317, all said slots being arranged at the foot instep region, approximately parallel to the raised portions provided on the shell.
  • the ends of the second slot 322 affecting the lateral wings 317a of the band-like elements 317 are again arranged approximately parallel to said raised portion, the ends of the first and third slots 321, 323 being instead arranged so as to diverge with respect to the second slot 322.
  • Fig. 6 illustrates a fourth embodiment, wherein a first slot 421, a second slot 422 and a third slot 423 are again provided on the band-like element 417.
  • All said slots, at the foot instep region, are approximately parallel to the raised portion provided on the shell, said slots being provided, at the ends affecting the flaps 417a of the band-like element 417, with a progressive decrease of the span.
  • Fig. 7 illustrates a fifth embodiment, illustrating a front quarter 507 and a band-like element 517 on which a first slot 521, a second slot 522 and a third slot 523 are provided.
  • said slots, at the foot instep region, are approximately parallel to said raised portion provided on the shell, in this region the span being constant.
  • each of said first, second and third slots has a span which progressively increases in width towards the ends of the wings 517a.
  • the graph of fig. 9 is respectively similar to the one indicated by the letter C (but with a value for the upper spans) and similar to the one indicated by the letter B, achieving, however, a better distribution of stresses.
  • Fig. 8 illustrates a sixth embodiment, wherein a first slot 621, a second slot 622 and a third slot 623 are provided on the band-like element 617, rigidly associated with the quarter 607, all said slots being approximately parallel to the raised portion provided on the shell, all having the same span, and being differentiated in that the longitudinal extension of the slots at the lateral wings 617a of the band-like element are different from one another in length.
  • said length increases starting from said first slot up to said third slot.
  • This embodiment allows to achieve variations in the flexibility characteristics by varying the ideal arm of rotation in flexing.
  • the number of slots may be any according to the specific requirements.
