Definitions

  • the present invention relates to an adjuster device for adjusting the position of the quarter with respect to the shell of a sports shoe.
  • FR-72.11273 discloses a device which comprises an actuation element to be fixed to the leg below the ankle and is directly or indirectly coupled to an automatic release system, so that an excessive forward inclination of the user's leg releases the boot from the binding.
  • DE-28 08 805 discloses a device for a boot whose purpose is to reduce the risk of breaking a leg during skiing.
  • Said device comprises a mechanism which connects the quarter directly to the heel unit of the binding, allowing to achieve rapid release of the boot if said boot tilts forward excessively.
  • the mechanism also allows to maintain the quarter in a skiing position, limiting its movement. This solution allows to render the actuation independent of the user's will, avoiding possible errors and oversights thereof.
  • US-4,379,370 discloses a device for adjusting the inclination of the quarter, particularly in ski boots, which comprises an abutment block which is associated with the rear part of the shell of a ski boot and is adapted to engage the quarter by contact in order to determine the angle, in the inactive position, between the longitudinal axis of the leg with which said quarter is associated and the longitudinal axis of the shell.
  • the abutment block can be arranged at various heights on the quarter in order to vary the angle.
  • EP-0 664 969 discloses a device for adjusting the inclination of the quarter and for prevent bending of the tip of the shoe in the skiing condition. The device disclosed is actuated by inserting the boot into the binding.
  • US-5,136,794 discloses a ski boot which has a mechanism for adjusting the position of the quarter with respect to a shell and in which said mechanism can be actuated simultaneously with the fastening of a lever. Accordingly, this solution, too, requires direct actuation by the user and an equally direct deactivation if the skier wishes to assume a position other than the one for skiing; however, for deactivation the skier must simultaneously loosen the closure of the boot, and this condition is undesirable in case of brief pauses in skiing, such as those due to waiting to access ski-lifts.
  • U.S. Patent Application S.N. 08/455,745 discloses a device for adjusting the position of a quarter with respect to the shell of a sports shoe which is characterized in that it comprises first means, associated with the quarter, for preselecting the chosen interaction between the quarter and the shell, second stable or temporary engagement means which are associated with said shell, and third means for interaction between said first preselection means and second engagement means which can be actuated by a movement applied to said quarter.
  • This solution allows to vary the inclination of the quarter with respect to the shell in three different and preset positions thanks to an actuation lever, which however must be actuated directly by the user.
  • the aim of the present invention is to solve the above-mentioned problems, eliminating the drawbacks of the cited prior art, by providing a device which allows to achieve an optimal and selected adjustment of the position of the quarter with respect to the shell of a sports shoe, achieving the skiing position, in which the backward oscillation of the quarter beyond a preset angle is blocked, or the walking position, in which the quarter can oscillate freely beyond said preset angle, without any direct intervention of the skier on any of the components that constitute the device.
  • An important object of the present invention is to provide a device which allows to avoid errors or oversights in arranging the quarter with respect to the shell.
  • Another important object of the present invention is to provide a device which is structurally simple and has small bulk and reduced weight.
  • Another object of the present invention is to provide a device which is reliable and safe in use, is free from malfunctions caused by ice or snow, and can be manufactured with conventional machines and equipment.
  • said actuator can be arranged at the sole of said shoe.
  • the reference numeral 1 schematically designates a sports shoe, such as for example a ski boot, which includes a shell 2 which is provided with a sole 3 and with which a quarter 4 is laterally rotatably associated.
  • Figs. 1 and 2 illustrate means for temporarily locking the position of the shell with respect to the quarter; said means are generally designated by the reference numeral 5 and are associated with the quarter proximate to its lower perimetric edge 6.
  • Said locking means comprise an enclosure 7 which can be accommodated in an adapted seat formed to the rear of the quarter and associated therewith by means of an adapted screw 8.
  • the enclosure 7 has, toward the surface that faces the outer lateral surface 9 of the shell 2, a first seat 10 for temporarily accommodating the tip of a tooth 11 which is pivoted transversely, at its other end, to said first seat by means of an adapted first pivot 12.
  • the tooth 11 can therefore oscillate from a position in which it is fully contained in the first seat 10 to a position in which it protrudes therefrom, being forced to do so by an adapted first spring 13 which is arranged coaxially to the first pivot 12.
  • the free end of the tooth 11 can be arranged at a second step-shaped seat 14 which is formed proximate to the upper perimetric edge 15 in the facing shell 2.
  • the tooth 11 has, at the end that is pivoted to the first pivot 12, a tab 16 which protrudes inside the quarter 4 in a region located above the upper perimetric edge 15 of the shell 2; a cup 17 is rigidly coupled to said tab 16 and is adapted to temporarily accommodate a cable termination 18.
  • Said cable termination is also connected to an adapted cable 19, which is slideable within an adapted sheath 20 which is associated inside the shell 2 and is adapted to convey the cable 19 at an actuator 21 which is located at the sole 3.
  • Said actuator is constituted by a guiding element 22 for the cable 19; said guiding element is perimetrically associated at a substantially cylindrical spacer 23, coaxially to which an axially movable annular element 24 is internally associated and a support 25 is externally associated; the entire assembly can be arranged and rigidly coupled, by means of a second screw 27, at an adapted third seat 26 formed in the sole 3 at the plate 28, which makes contact with the ground or the snow.
  • buttons 29 which is perimetrically associated with one end of the support 25 in a region located above the annular element 24.
  • the button 29 accordingly has an end which protrudes outside the plate 28; the other end interacts with an adapted gasket 30 which is interposed between said button 29, said annular element 24, said support 25 and said spacer 23, as shown in Fig. 1.
  • a cable retainer 31 for the cable 19 is associated axially with respect to the button 29 and a mushroom-shaped element 32 is associated coaxially with respect to the cable retainer 31 and is located in an axial seat of the annular element 24.
  • the actuator 21 also comprises a second spring 33 and a third spring 34 which are arranged coaxially to each other and are interposed between said annular element 24 and said guiding element 22.
  • the illustrated device can therefore be actuated whenever the plate 28 associated with the heel of the boot makes contact with the ground or with any other resting surface and therefore for example at each step during walking and while the boot is inserted at a suitable binding of a ski.
  • the weight force applied to the heel region in fact allows a vertical movement of the button 29 which forces the axial movement of the annular element 24 by virtue of the possibility to compress the second spring 33 and the third spring 34, as shown in Fig. 2.
  • the arrangement of the button 29 within the seat formed in the plate 28 allows to loosen the cable 19, accordingly allowing, by means of the first spring 13, to force the protrusion of the tooth 11 from the first seat 10.
  • the quarter 3 is in a more vertical position than the one normally used during skiing, and therefore the continuous actuation and deactivation of the device due to the resting of the heel on the ground does not entail the locking of the quarter, because the tooth 11 is located too low to be able to interact with the second seat 14 formed in the shell 2, due to the fact that the leg is extended forward during this phase of walking.
  • the engagement of the tooth 11 with the second seat 14, in order to achieve the skiing condition can be achieved only after the forward rotation of the quarter in addition to the simultaneous activation of the button 29.
  • the invention has achieved the intended aim and objects, a device having been obtained which ensures the arrangement of the quarter in the skiing position whenever the boot is associated with the binding, without the skier having to perform any intervention on the individual components of the device.
  • the skier can pass to the walking condition simply by lifting the boot from the binding.
  • the device therefore allows to avoid errors or oversights in positioning the quarter with respect to the shell, automatically achieving an arrangement of the quarter with respect to the shell which allows skiing or walking.
  • figs. 3 and 4 illustrate another embodiment, in which the means 105 are associated at the shell 102 proximate to its upper perimetric edge 115.
  • the sheath 120 and the end part of the cable 119 slide within an adapted enclosure 107 which is rigidly coupled at said upper perimetric edge 115 of the shell 102 and is then blocked outside said enclosure at a cable termination 118.
  • Said termination is accommodated at a tooth 111 whose free end is directed away from the plate 128 associated with the sole 103; at the opposite end, the tooth 111 is pivoted transversely to the enclosure 107 by means of an adapted first pivot 112.
  • a first spring 113 is also present coaxially to said pivot and is adapted to force the protrusion of the free end of the tooth 111 from an adapted first seat 110 formed in said enclosure 107.
  • a second step-shaped seat 114 is formed at the inner lateral surface 135 of the quarter 104, and the free end of the tooth 111 can interact by abutment therewith in the skiing condition, shown in Fig. 4.
  • the operation of the device can be deduced from the above described solution, since the actuation or lack of actuation of the button 129 entails the release or lack of release of the cable 119 and therefore allows or disallows the first spring 113 to force the free end of the tooth 111 toward the facing inner lateral surface 135 of the quarter 104 until it is arranged, in the skiing condition and therefore with the quarter rotated forwards, at the second seat 114.
  • the inclination of the quarter with respect to the shell is of course preset during design, so as to ensure that the user has an anatomically correct skiing position.
  • the actuation of the device is in any case independent of the will of the user, avoiding incorrect actuations or accidental oversights.
