Definitions

  • the present invention relates to an inclination adjustment device particularly for sports shoes such as boots or skates.
  • ski boots can entail problems for a large number of users, since they have to meet two contrasting requirements.
  • ski boots In view of the need to provide products that have a high degree of standardization, commonly used known ski boots have a certain number of adjustments, aimed at providing the best adaptation of the sports implement to the physical configuration of the user.
  • the cross-member determines the position of a hole along the longitudinal axis of the body of the adjustment member depending on the position assumed inside the opening.
  • this device allows to vary the lateral inclination of the rear quarter with respect to the shell, it is constituted constructively by a plurality of components, which require particular work at the points of the boot where they are applied.
  • the device therefore, has considerable costs and requires specific components intended for this operation alone.
  • the ends of the complementarily threaded screws are respectively associated with the shell at a region that is adjacent to the tip of the foot and at the end of the front quarter that lies above the shell, at the foot instep region.
  • French patent no. 2,570,936, filed on 2 October 1984 is also known and describes a ski boot of the rear-entry type, in which canting can be adjusted by virtue of the presence of a head member provided with a slot that cooperates with a means that is shaped complementarily to the end of the pivoting shaft that affects two parts of the boot, the head member being blocked in a translational motion along an axis that is transverse to the longitudinal axis of the shaft by virtue of the presence of an elastically deformable means.
  • a canting adjustment device which has a stud provided with a surface that is profiled so as to mate with a contoured portion that is generally composed of a plurality of teeth and is provided on a front quarter.
  • the stud can be disengaged from contact with the contoured portion so that it can be moved and coupled again with it in a different position, since the contoured portion formed on the front quarter is larger than the profiled surface of the stud.
  • this minimum value is currently equal to approximately 3 millimeters.
  • any canting adjustment cannot provide for a relative translational motion of the front quarter by less than the above cited minimum pitch, and this is not entirely satisfactory for users.
  • the aim of the present invention is therefore to solve the cited technical problems, eliminating the drawbacks of the cited known art and thus providing an invention that allows to achieve fine adjustment of canting without increasing the complexity of the device with respect to what is provided by the background art.
  • an important object is to provide an invention that can be operated easily by the skier, so as to obtain easily the intended adjustment.
  • Another object is to ensure maximum reliability and safety in use, so as to allow the skier at all times to have adequate control over the skis.
  • Another object is to provide an invention that is structurally simple and has modest manufacturing costs.
  • an inclination adjustment device particularly for sports shoes such as boots or skates, which includes a quarter that is articulated, in the malleolar region, by virtue of a stud, to a shell, characterized in that the stud has a first toothed region that cooperates selectively with a second toothed region, which is formed on the quarter and is orientated approximately transversely thereto and is longitudinally longer than the first region, the stud having a first hole for a pivot for detachable connection to the shell, which is formed in a region that is intermediate between two consecutive teeth and does not coincide with a central axis of the stud.
  • the reference numeral 1 designates a ski boot that is composed of a quarter 2 and a shell 15, which are mutually articulated by virtue of an adjustment device according to the invention, designated by the reference numeral 25.
  • the quarter 2 is arranged laterally with respect to the shell 15 and can perform a translational motion, with respect to it, in a substantially vertical direction, assuming relative positions defined by the adjustment device 25.
  • a through slot 3 which in a particular but not exclusive embodiment is arranged so that the major axis of its cross-section is orientated substantially vertically and is therefore approximately perpendicular to the sole of the boot.
  • a first toothed region 5 is formed on the bottom of the receptacle 4, and its profile is constituted by a plurality of first teeth 6, which are arranged transversely with respect to the major axis of the slot 3 and have a preset pitch.
  • the pitch does not decrease, due to mechanical strength reasons, below a chosen minimum threshold.
  • the device 1 furthermore, is formed by a stud 7, which is essentially T-shaped and includes an actuation head 12, below which there is a coupling body 9 whose shape duplicates the shape of the receptacle 4 but is smaller at the major axis.
  • the coupling body 9 has, on the opposite side with respect to the actuation head 12, a second toothed region 10, whose profile is constituted by a plurality of second teeth 11, whose shape is such that they can mesh with the first teeth 6, formed in the first toothed region 5, and have the same pitch, so that the stud 7 can be positioned selectively with respect to the quarter 2 along a direction that coincides with the major axis of the through slot 3 and of the receptacle 4.
  • the stud 7 furthermore includes a lug 8, which is essentially cylindrical and protrudes at the second toothed region, on the opposite side with respect to the actuation head 12.
  • the lug 8 can be positioned so that it can slide within the through slot 3, since its diameter is slightly smaller than the width of the slot 3, so that it can perform a translational motion therein, allowing the stud 7 to be guided during its relative movement with respect to the quarter 2.
  • the lug 8 can be rotated while remaining at least partially inside the through slot 3.
  • the mutual and selective arrangement of the first and second toothed regions 5 and 10, and the possible corresponding movement of the lug 8 within the through slot 3, allow the stud 7 to assume various positions, in each of which the second teeth 11 of the second toothed region 10 couple with a fraction of first teeth 6 of the first toothed region 5.
  • the actuation head 12 which has by way of example a circular cross-section, is meant to constitute a grip member for the actuation of the device 1 by the user and a protection for the first and second toothed regions 5 and 10.
  • a cavity 18 is formed on the actuation head 12 of the stud 7, on the opposite side with respect to the first toothed region 5 and through part of its thickness and is open in an upward region and forms, in a downward region, a preferably flat abutment surface 19.
  • a first through hole 13 is formed in the stud 7, and its axis coincides with the axis of the lug 8.
  • a pivot 14, provided at a first end with a head 14a, can be inserted in the first hole 13, so that the head 14a can abut against the abutment surface 19.
  • the stem 14b of the pivot 14 has a slightly smaller diameter than the first hole 13, so as to allow a relative rotation between the pivot and the stud 7 about the axis 20 of the first hole 13.
  • a second through hole 16 is formed in the lateral surface of the shell 15, approximately in the malleolar region, and a locking member 17 is accommodated inside it and can be connected, at a second end of the pivot 14 that lies opposite the one where the head 14a is formed, so as to fasten the stud 7, and therefore the quarter 2, to the shell 15.
  • the pivot 14 can move axially with respect to the locking member 17, so that it can pass from a first position, termed closure position, in which it retains, by virtue of its head 14a, the stud 7 against the quarter, to a second position, termed adjustment position, in which the head moves away from the stud 7, allowing it to disconnect from the quarter 2, so that the first and first toothed regions 5 and 10 are disengaged and the coupling body 9 is extracted from the receptacle 4, and vice versa.
  • closure position in which it retains, by virtue of its head 14a, the stud 7 against the quarter
  • adjustment position in which the head moves away from the stud 7, allowing it to disconnect from the quarter 2
  • This function can be achieved for example by virtue of the presence of a thread, which is formed in the end region of the pivot 14 that lies opposite the end where the head is present and is suitable to engage a corresponding thread provided on the locking member 17, which is constituted by way of example by a nut.
  • the second hole 13 has a longitudinal axis 20 that is arranged in an intermediate region between two consecutive teeth of the second toothed region 10 that does not coincide with the central axis 21 of the actuation head 12 of the stud 7.
  • the axis 20 is arranged in any position of the profile of the second teeth 11, except for the positions that correspond to a apex or base of the second teeth 11 or are arranged at a distance from any one of the apexes or bases that is equal to a whole multiple of the pitch of the first teeth 6 and of the second teeth 11.
  • the distance between the axis 20 and any one of the apexes or bases of the first or second teeth 6 and 11 can be equal to one quarter of the pitch of the first and second teeth; however, equally advantageous results can be achieved with different distances.
  • a first series of notches 22 and a second series of notches 23 can be provided conveniently on the outer lateral surface of the quarter 2, proximate to the receptacle 4; these notches indicate, in cooperation with the position indicator 24 provided on the upper surface of the actuation head 12 of the stud 7, the correct position that the stud must assume in order to obtain a given adjustment of the canting angle of the sports shoe.
  • each series are mutually spaced, along the direction of motion of the stud 7 with respect to the quarter 2, by a distance equal to the pitch of the first teeth 6 and of the second teeth 11, while the two series are advantageously mutually staggered, in the same direction, by a distance equal to half of the pitch.
  • the operation of the adjustment device according to the invention provides for two operating modes, capable of allowing a respectively more or less significant variation of the angle of the quarter.
  • adjustment is performed by placing the pivot 14 in the adjustment position and partially extracting the stud 7 from the receptacle 4, so as to mutually separate the first and second toothed regions.
  • the stud 7 can be moved by sliding the lug 8 within the through slot 3 according to the direction in which the adjustment is to be performed, so that the first toothed region 5 is coupled to the second toothed region 10 at a different portion of the first teeth 6.
  • the stud 7 is fixed in the position that has been reached by locking the pivot 14.
  • the stud 7 performs a translational motion with respect to the quarter 2 by a distance that is equal to a whole multiple of the pitch of the first teeth 6 and of the second teeth 11, so that the reaction of the shell 15 applies, by virtue of the pivot 14 and the stud 7, a force to the quarter 2 that acts so as to force it to perform a translational motion that is equal to the translational motion performed by the stud 7 with respect to the through slot 3 and is directed in the opposite direction.
  • the stud 7 is thus stationary with respect to the shell 15, and only the quarter 2 moves, for example vertically, adjusting the canting of the boot.
  • the stud 7 In the second operating mode, instead, once the pivot 14 has been loosened, the stud 7, after being raised so that the first and second toothed regions 5 and 10 are disconnected and the coupling body 9 is extracted from the receptacle 4, is rotated appropriately through 180° about the axis of the first hole 13 by virtue of the support provided by the pivot 14.
  • the quarter In order to reinsert the stud 7 in the quarter 2 so that once the coupling body 9 has been reinserted in the receptacle 4 the second toothed region 10 is coupled to the first toothed region 10 at the same portion of the second teeth 11 with which it was coupled prior to the adjustment, the quarter must undergo a relative translational motion with respect to the shell 15 and the stud 7 in the direction in which the quarter 2 moves with respect to the shell 15.
  • This translational motion is equal to twice the distance of the axis 20 of the first hole 13 with respect to the nearest apex or base of the second teeth.
  • the fine canting adjustment performed in the manner described above entails a movement of the quarter in the intended direction that is equal to half the pitch of the first teeth 6 and of the second teeth 11.
  • the minimum dimension of the pitch of the first teeth 6 and of the second teeth 11 allowed by current technologies and materials is equal to approximately three millimeters, since the use of thicknesses of the first and second teeth 6 and 11 that are below this limit would entail a high risk of breakage thereof during use.
  • a movement of the stud 7 that entails the transfer of the position indicator 24 from one notch to the next of the same series, as shown in Figures 5 and 6, indicates a translational motion of the quarter 2 by a distance equal to the pitch of the first and second teeth 6 and 11, while the passage from one notch to the corresponding notch of the opposite series, as shown in Figures 6 and 7, produces a movement equal to half of the pitch.
  • Figure 8 illustrates, by way of example, three configurations of the canting of a ski boot, which can be obtained by virtue of the simple translational motion of the quarter 2 with respect to the stud 7.
  • the configuration D shown in Figure 9 can be obtained, starting from the configuration A, by virtue of a rotation of the stud 7 about the axis of the first hole 13 that is equal to 180°.
  • This action entails, as described above, a translational motion of the quarter 2 with respect to the shell 15 and to the stud 7 by a distance equal to half the pitch of the first and second teeth.
  • Figure 10 illustrates, in a normal view and in a partially sectional view, the relative arrangements of the quarter 2 and of the stud 7 that correspond to the adjustments shown in Figures 8 and 9.
  • the adjustment device described here can be present on just one side or on both sides of the ski boot, ensuring in either case the operation described above.
  • the adjustment device according to the invention fully achieves the intended aim, since it allows to obtain an adjustment of the canting of a ski boot more accurately than allowed by known systems without requiring a new sizing of the components or the introduction of additional components, thus ensuring a level of safety in use that is at least equal to that of known devices.
  • Another object achieved by the invention is to allow easy adjustment on the part of the user, allowing to obtain directly and safely the configuration that is most suitable for the user's requirements.
  • Another object achieved by the adjustment device according to the invention is to allow the user better control over the skis, since the finer adjustment and therefore the high level of adaptation to the physical characteristics of the user allow the user to be more confident in using the skis.
