Definitions

  • the present invention relates to a flex control device particularly for a motocross boot.
  • Boots are currently used, particularly for practicing motocross, which comprise a soft upper with which stiffening and protection elements are associated; such elements are typically made of rigid plastic material, such as for example front plates, a toe cap, a heel counter and a rear cuff.
  • EPA. 03016526.0 of July 23, 2003 discloses a sports shoe, particularly for the practice of motocross, which comprises a soft upper with the rear of which a semirigid cuff, which partially surrounds the lower part of the leg of the user, and a semirigid counter, which wraps around the heel of the user, are separately associated.
  • Such sports shoe comprises an additional semirigid element which is approximately cross-shaped so as to form two first wings, which are arranged approximately vertically and to the rear and longitudinally with respect to the upper, and two second wings, which are arranged approximately transversely to the upper so as to wrap laterally around the malleolar region.
  • the first two wings form respectively a first tab, which protrudes approximately vertically toward the overlying cuff, and a second tab, which protrudes approximately vertically towards the underlying counter, and engage slidingly respectively in first and second receptacles formed respectively in the cuff and in the counter.
  • a reinforcement element adapted to protect the malleoli is provided at the tips of the second wings, and third and fourth tabs protrude from said reinforcement element respectively toward the cuff and toward the counter and engage slidingly respectively third and fourth receptacles formed respectively in the cuff and in the counter.
  • the positioning distances between the counter, the semirigid element and the cuff allow the sliding engagement of the various tabs in the respective receptacles, so as to allow the foot of the user to perform both forward or backward flexing and lateral movement to the right or to the left or a combination thereof; said sports shoe allows the user to maintain very good foot insertion, to perform a correct and guided movement of the system formed by the foot and the ankle, and at the same time ensures support and protection of said foot and ankle.
  • This riding position particularly during landing after a jump, which is frequent during motocross, entails a large and sudden flexing of the tibia toward the toe of the foot, thus imparting considerable stresses to the Achilles tendon, which can lead to inflammation or even rupture thereof.
  • the aim of the present invention is to solve the above described problems, eliminating the drawbacks of the cited background art, by providing a device which allows to provide, particularly during the practice of motocross, adequate protection to the Achilles tendon of the user.
  • an object of the invention is to provide a device which can be adapted quickly and easily to the various riding positions which can be adopted by each user and to the different shapes of the leg and of the foot of the various users.
  • Another object is to provide a device which is structurally simple and has low manufacturing costs.
  • a flex control device particularly for the quarter of a motocross boot, which comprises a soft upper provided at the rear with a semirigid cuff and a semirigid counter, which are connected respectively to said upper and to said upper and/or sole, characterized in that it is constituted by a first rod-like element and a second rod-like element, the first rod-like element being rigidly coupled to said counter, the second one being selectively associable with said quarter, said first and second rod-like elements being slidingly associated in contrast with at least one elastically deformable element.
  • the reference numeral 1 designates a motocross boot which comprises a soft upper 2, which is preferably shaped like an ankle-boot so as to form a lower portion 3, which during use covers the foot of the user, and a contiguous quarter 4, which affects the region from the ankle up to part of the tibia.
  • a sole 5 is associated in a lower region with the upper 2 and is provided at the rear with a heel 6.
  • a semirigid cuff 7 is rigidly associated or provided to the rear of the upper 2, in the region of the quarter 4, and during use wraps around the lower and rear part of the leg of the user.
  • a semirigid counter 8 is associated with the lower portion 3 of the upper 2 at the rear, at the region of the heel 6, surrounds the heel of the user during use and is connected to the upper 2 and/or the sole 5.
  • a semirigid element 9 is associated or rigidly coupled to the upper 2 and is approximately cross-shaped so as to form two first wings 10a, 10b, which are arranged approximately vertically and to the rear and longitudinally with respect to the upper 2, and two second wings 11a, 11b, which are arranged approximately transversely to the upper 2, so as to wrap around, in a rear region, the adjacent region of the leg and laterally the malleoli.
  • the two first wings 10a and 10b form respectively a first upper tab 12, which protrudes approximately vertically toward the overlying cuff 7, and a second lower tab 13, which protrudes approximately vertically toward the underlying counter 8; said tabs engage slidingly respectively in first and second receptacles or seats, designated respectively by the reference numerals 14 and 15 and provided respectively within the cuff 7 and the counter 8.
  • a thicker region or reinforcement element 16 which is adapted to protect the malleoli and from which a third tab and a fourth tab, designated respectively by the reference numerals 17 and 18, protrude respectively toward the cuff 7 and the counter 8 and engage slidingly and respectively third and fourth receptacles or seats, which are not shown in the accompanying figures and are provided respectively inside the cuff 7 and the counter 8.
  • the boot 1 comprises at least one device 50 for controlling the flexing of the quarter 4, which is constituted advantageously by a first rod-like element and a second rod-like element, designated respectively by the reference numerals 19 and 20, which are respectively rigidly coupled to the counter 8 and selectively associable with said cuff.
  • first rod-like element 19 and the second rod-like element 20 lie, during use, on planes which are substantially parallel and mutually spaced.
  • the first and second rod-like elements can slide freely with respect to the semirigid element 9, if provided, preferably without making direct contact therewith.
  • the first rod-like element 19 is constituted by a first strip 21, which is fixed inside the counter 8, for example by means of one or more fixing elements such as screws or rivets 22 associated with an appropriately provided first hole 23 which is formed at the end of the first strip 21, which is adjacent to the sole 5.
  • the first rod-like element 19 protrudes upward with respect to the counter 8 and is arranged so that the respective first rods 24a and 24b lie approximately at a central region of the semirigid element 9.
  • the first rod-like element 9 cooperates with appropriately provided first guiding means for guiding the sliding motion with respect to the counter 8, said first guiding means being constituted advantageously by a first bridge 26, which protrudes inside the counter 8 and surrounds, during use, the first strip 21, so as to keep it slidingly coupled to the counter 8.
  • the second rod-like element 20 comprises a second strip 27, which is slidingly and selectively associable with the cuff 7 by way of adjusting means for adjusting its position.
  • Two second rods protrude axially from the end of the second strip 27 which is directed toward the counter 8, have a preferably approximately circular cross-section, are approximately mutually parallel, and lie approximately on the same plane of arrangement as the second strip 27; advantageously, the second free ends, designated respectively by the reference numerals 29a and 29b, of the second rods 28a and 28b are bent approximately at right angles on mutually opposite sides.
  • the second rod-like element 20 protrudes below the cuff 7, being arranged so that the respective second rods 28a, 28b lie at an approximately central region of the semirigid element 9, if provided, so that the second rods 28a and 28b are superimposed and spaced with respect to the first rods 24a, 24b of the first rod-like element 19; advantageously, the second free ends 29a, 29b of the second rods 28a, 28b are positioned at a lower height than the first free ends 25a, 25b of the contiguous first rods 24a, 24b.
  • the position of the second strip 27 with respect to the cuff 7 is guided by appropriately provided second guiding means, which are constituted advantageously by a second bridge 30, which protrudes inside the cuff 7 and surrounds, during use, the second strip 27, so as to keep it slidingly coupled to the cuff 7.
  • second guiding means which are constituted advantageously by a second bridge 30, which protrudes inside the cuff 7 and surrounds, during use, the second strip 27, so as to keep it slidingly coupled to the cuff 7.
  • the first and second rod-like elements are mutually slidingly associated in contrast with at least one elastically deformable element, which is constituted advantageously by at least one spring 31 which is arranged coaxially to the first and second rods and is interposed between the first and second free ends of said first and second rods.
  • the spring 31 is preloaded, so that it applies constantly a thrust to the first and second free ends of the first and second rods, respectively; the thrust of the spring 31 tends to move the first free ends 25a, 25b away from the second free ends 29a, 29b, so as to move mutually closer, in the longitudinal direction, the first strip 21 and the second strip 27.
  • the means for adjusting the position of the second rod-like element 20 with respect to the cuff 7 are constituted by a plate 32, which is approximately U-shaped in plan view so as to form an approximately flat base 33, which during use is arranged approximately parallel to the second strip 27 on the opposite side with respect to the cuff 7.
  • a pin 34 protrudes approximately at right angles to the base 33 toward the second strip 27 and can engage selectively, during use, one of one or more second holes 35 which are provided in the second strip 27 and are advantageously aligned approximately along the longitudinal central axis of said strip.
  • Two arms designated respectively by the reference numerals 36a and 36b, protrude at right angles to the base 33 and are arranged during use so as to surround laterally the second strip 27, protruding with their respective free ends through two appropriately provided slots 37a, 37b formed in the cuff 7.
  • the mutual distance between the base 33 and the second strip 27 can be adjusted by way of appropriate distance adjustment means, so as to allow insertion or extraction of the pin 34 with respect to the chosen hole among the second holes 35.
  • Said adjustment means are constituted advantageously by a lever 38, which is arranged outside the cuff 7 and is supported rotatably between the free ends of the arms 36a and 36b.
  • the lever 38 is cam-shaped at its region for pivoting to the arms 36a and 36b; its interaction with the outer surface of the cuff 7 allows to vary the distance of the base 33 from the latter and therefore from the second strip 27.
  • the base 33 moves respectively toward or away from the second strip 27 and the pin 34 is consequently inserted in, or extracted from, one of the second holes 35, so as to rigidly couple or disengage the second rod-like element 20 with respect to the cuff 7.
  • the degree of compression of the spring 31 is increased and the effort required to move mutually apart the first and second strips is therefore increased; vice versa, by reducing the distance between the second rod-like element 20 and the counter 8, the spring 31 reduces its degree of preloading, and a smaller effort is sufficient to move mutually apart the first and second strips.
  • the invention has achieved the intended aim and objects, a device having been devised which allows to control the flexing of the quarter of a motocross boot so as to ensure adequate protection both of the foot and of the ankle of the user, and in particular of the Achilles tendon of said user, at the same time allowing the foot and the ankle to perform all the movements required to control the motorcycle.
  • the possibility to adjust the degree of preloading of the spring allows to achieve a chosen degree of control of the flexing of the quarter, so as to adapt for example to the various riding positions assumed and to the various body shapes of the users.
  • the production costs of the device according to the invention remain low, since it is provided by means of components which are easy to manufacture and/or assemble.
