ADJUSTMENT DEVICE PARTICULARLY FOR SKI BOOTS

Abstract: Device for ski boots comprising a front quarter (1002) and a rear quarter (1003) associated with a shell (1004) and/or an upper quarter (1005) embracing at least one portion of the leg of a skier and supported at the upper end of said front and/or rear quarter(s). The device has a slider (1014) which is movable transversely to said upper quarter and/or front quarter and/or rear quarter and/or shell, and interacts selectively with at least two separate abutments (1011,1012) provided on said upper quarter and/or front quarter and/or rear quarter and/or shell.

Description: The present invention relates to an adjustment device particularly for adjusting the flexing stroke or the inclination of ski boots. Various devices are currently known which allow to adjust the technical characteristics of a ski boot such as the front or rear support degree, the extent of the flexing stroke or the longitudinal inclination of the quarter with respect to the shell. U.S. patent No. 3,729,842 discloses a ski boot wherein the adjustment of the longitudinal inclination between the quarter and the shell of a front-entry boot is provided by means to two separate plates, one coupled to the quarter and the other to the shell, having a region of superimposition at which an eccentric is associated. This known device has, however, some disadvantages, among which there is a condition of unstable equilibrium of the position of the eccentric while skiing. This may cause the sudden disengagement of the eccentric from its selected position, the adjustment of the inclination being thus lost. German patent DE 2807371 discloses the use of at least one eccentric having its rotation point located at the shell or at the quarter of a ski boot wherein the quarter is pivotally fixed to the shell. Also in this case, however, the use of the eccentric, which adjusts the inclination of the quarter with respect to the shell, leads to a condition of unstable equilibrium while from an ergonomic viewpoint to rotate the eccentric the skier has to exert a fatiguing torsional movement with the arm. As a partial solution to these disadvantages, this same Applicant filed a European Patent Application No. 87100151. 7 on January 8, 1987, disclosing a support adjuster for ski boot quarters the peculiarity whereof resides in the fact that it comprises a shaped body which embraces at least one portion of the leg of the skier and is supported at the upper end of the quarter of a ski boot, and in that it has removable locking means for the location of said shaped body with respect to said quarter. Though this adjuster is undoubtedly effective, it is however complicated from a manufacturing point of view and is therefore little economical. The aim of the present invention is to eliminate the disadvantages described above in known ski boots by providing a device which allows, depending on its arrangement, to obtain the adjustment of the support or of the flexing stroke or of the inclination in ski boots. Within the scope of the above described aim, an important object is to provide a structurally simply device, therefore easily applicable to a ski boot so as to be economically very competitive. Still another important object is to provide a device which allows the skier to select stable positions while skiing. Yet another object is to provide a device which does not subject the skier's arm to any fatiguing torsion while operating it. Not least object is to provide a device having an easy and swift operation. This aim and these objects, as well as others which will become apparent hereinafter, are achieved by an adjustment device for boots, particularly for ski boots comprising at least one first and one second mutually movable elements, characterized in that it comprises at least one slider slideable on one of said elements of said boot and interacting with at least one abutment element fixed on the other of said elements of said boot and functioning as a guiding seat for the slider.

With reference to the above described figures, the device is applicable at ski boots 1 comprising a front quarter 2 and a rear quarter 3, associated with a shell 4, and an upper quarter 5. The upper quarter embraces at least one portion of the leg of the skier and has a pair of lateral wings 6 rotatably supported, by means of adapted pivots or rivets 7, at shoulders 8 protruding upwardly and laterally to the rear quarter 3. The device comprises a substantially T-shaped slider 9 having a protrusion 10 projecting transversely to the wings 11 of the opposite side with respect to its stem 12. The slider 9 is slideably associated at a slot 13 provided transversely to the upper quarter 5; the protrusion 10, arranged along an axis which is longitudinal to the rear quarter 3, protrudes alone from said slot. A preferably elastically deformable tap 14 protrudes at the upper end of said rear quarter; the upper end of the tab 14 interacts with the inner surface of the upper quarter 5, a guiding seat 15, for the stem 12 of the slider 9, being provided at the region of the slot 13. Said seat 15 is in the shape of an inverted S, two separate abutments for the stem 12 being therefore defined at its ends. The use of the device is as follows: once the ski boot is on, the skier, by gripping the projection 10, imparts a leftward or rightward movement of the slider 9 which is followed by a translatory motion of the stem 12 at the seat 15 which forces the upper quarter 5 to to vary its inclination with respect to the rear quarter 3. An adjustment of the rear support is thus achieved by means of a swift and easy operation. The device is furthermore structurally very simple, it allows the selection of stable positions while skiing and is economically very competitive. Naturally the seat 15 may be provided directly at the rear quarter 3 by making the upper quarter 5 partially embrace the latter. The configuration of the seat 15 may also be the most appropriate, it being possible to provide even more than two separate abutments for the stem 12 of the slider 9. Figures 3 and 4 illustrate a first variated aspect of a ski boot 101 having an upper quarter 105 provided with a pair of lateral wings 106 laterally supported at the upper end of the front quarter 102, preferably in a pivotable manner. A slot 113 is provided transversely to the upper quarter 105 at the tibial resting region and the slider 109 has a jut 110 protruding from the slot 113. The stem 112 of said slider interacts with at least two separate abutments 115a and 115b provided by conveniently shaping the upper edge 116 of the front quarter 102 which is arranged facing the inner surface of the upper quarter 105 at the region of the slot 113. An adjustment of the forward support is thus obtainable, since by moving the slider 109 transversely within the slot 113 its stem 112 is located at the two separate abutments 115a and 115b which naturally have different depths. Naturally a similar configuration may be devised having the slot provided at the front quarter and the abutments provided at the upper quarter. Figures 5 and 6 illustrate such an embodiment, wherein on the front quarter 202 of the ski boot 201 a transverse slot 213 is provided, proximate to its front perimetral edge 217 and in the region overlying the foot instep. The slider 209 is slideably accommodatable within said slot, and it is positioned with respect to said slot by gripping the jut 210. The stem 212 of the slider 209 interacts with at least two separate abutments 215a, 215b provided at the ends of a flap 214 protruding longitudinally to the upper quarter 205 which is rotatably and/or slideably associated with the front quarter 202. The upper quarter 205 in fact has adapted slots 218 for its sliding with respect to the pivots 207 which connect the upper quarter to the front quarter. In this case, too, an adjustment of the forward support and therefore of the stroke of the tibial support during flexing is achieved. Figures 7 and 8 illustrate a third embodiment wherein the slot 313 is provided directly at the front quarter 302 proximate to its front perimetral edge 317 and in the region approximately overlying the foot instep. Slider 309 is slideably associable within the slot; the stem 312 of the slider interacts with adapted separate abutment 315a and 315b, formed at a raised portion 319 provided on the shell 304 in the region approximately underlying the slot 313. It is possible to obtain an adjustment of the flexing stroke while skiing. Figures 9 and 10 illustrate a fourth embodiment, wherein the slot 413 is provided at the front quarter 402 proximate to its front perimetral edge 417 and approximately at the foot instep region. The raised portion 419 provided at the shell 404, has at least two separate abutments 415a, 415b interacting with the stem 412 of the slider 409 upon a rotation of the front quarter 402 in the direction of the rear quarter 403. It is thus possible to obtain an adjustment of the longitudinal inclination of the front quarter with respect to the shell. Figures 11 and 12 illustrate a fifth embodiment, wherein the slider 509 is slideably associated at a slot 513, provided transversely to the quarter 503 of a front-entry boot and proximate to its lower perimetral edge 520. The stem 512 of the slider 509 interacts with at least two separate abutments 515a, 515b, defined at a raised portion 519 which protrudes from the shell 504 at the slot 513. Said abutments have their surface of interaction with the stem of the slider directed towards the heel of the boot. It is thus possible to obtain the adjustment of the flexing stroke of the quarter of the boot. An equivalent embodiment of this case, is the accommodation of the slider at the shell, with the related abutments provided at the quarter. Figures 13 and 14 illustrate a sixth embodiment, wherein the raised portion 619 is provided so that the surfaces of the abutments 615a and 615b , interacting with the stem 612 of the slider 609, are directed towards the upper end of the quarter 603 of the front-entry ski boot 601. In this case, too, it is thus possible to obtain the adjustment of the longitudinal inclination of the quarter 603 with respect to the shell 604. Figures 15 and 16 illustrate a seventh embodiment wherein the slider 709 has its stem 712 interacting with the surfaces of at least two separate abutments 715a and 715b directed towards the heel of the rear-entry boot 701. In this case the slot 713 is provided at the rear quarter 703 proximate to the lower perimetral edge 720 thereof in a region overlying the two separate abutments. In this case, too, the slider has a jut 710 projecting from the wings 711 for the grip of the skier. Figures 17 and 18 illustrate a ski boot 801 having a front quarter 802 with a front perimetral edge 817. Longitudinally to said boot, a tab 814 protrudes beyond the edge 817 and has at least two separate abutments 815a and 815b at its free end. A first transverse slot 813a, in which a slider 809 is slideable accommodatable, is provided on the shell 804 at a raised portion 819. At the raised portion 819, the free end of the tab, or flap, 814 passes freely within a second slot 813b, provided on said raised portion along an axis which is longitudinal to the boot. The abutments 815a and 815b can thus interact with the stem 812 of the slider 809. The wings 811 of the slider are slideably accommodated within two guides 824 and 825 provided on the inner surface 826 of the shell 804 proximate to the longitudinal ends of the first slot 813a. Figures 21-24 illustrate an adjustment device according to a further embodiment of the invention and applicable at rear-entry ski boots 1001, constituted by a front quarter 1002 and by a rear quarter 1003 associated with a shell 1004 and comprising an upper quarter 1005, or at monolithic ski boots wherein the front quarter 1002 is provided integrally with the shell 1004. The upper quarter 1005 embraces a portion of the front part of the leg of the skier and is locatable internally to the front quarter 1002 proximate to the upper end 1006 thereof. The quarter 1002 is frontally provided with a vertical slot 1007, approximately at its middle longitudinal axis, to allow the elastic deformation of said front quarter 1002 upon a forward flexing of the skier's leg. Said upper quarter 1005 is associated at least with the sides of the front quarter 1002, e.g. by means of adapted small pins 1008a and 1008b which pass within adapted holes 1009 provided laterally to said front quarter 1002 or to said upper quarter. At least one second guide, constituted for example by a slot 1010 arranged so as to allow the sliding of the upper quarter with respect to the front quarter 1002, is conveniently provided at said holes 1009 laterally to said upper quarter 1005. At least at one side of said front quarter there is a first guide 1011 arranged along an axis approximately parallel to the longitudinal axis of said front quarter 1002. At said first guide 1011 said upper quarter 1005 has a substantially L-shaped seat 1012. One wing of the seat 1012 is directed towards the rear quarter 1003 and the other wing towards the upper end 1006 of said upper quarter 1005. The stem 1013 of a substantially T-shaped slider 1014, actuatable by the skier, is arrangeable within said first guide 1011 and said seat 1012. The use of the device is as follows: to adjust the flexibility it is sufficient to impart a translatory motion to the slider 1014 within the first guide 1011. In the condition illustrated in figures 22 and 23, i.e. with the slider 1014 having its stem at the crossing point of the wings of the seat 1012, upon a forward flexing said stem 1013 can slide at the wing of the seat 1012 which is directed towards the rear quarter 1003. Vice versa by arranging the slider at the opposite end of the first guide 1011 said sliding is prevented, thus making the boot rigid. It is naturally possible to provide a seat 1012 having a plurality of wings directed towards the rear quarter 1003 and having different depths so as to obtain a further diversification of the degree of adjustment of the flexibility. Naturally, as illustrated in figure 24, on the front quarter 1002 it is possible to provide a pair of first guides 1011a and 1011b, identical to one another and specular with respect to the longitudinal middle plane of the boot. The guides 1011a and 1011b act as seats for the stems 1013a and 1013b of a pair of slides 1014a and 1014b, said stems being slideable within a a pair of seats 1012a and 1012b provided on said upper quarter 1005. Figures 25, 26 and 27 illustrate a boot 1101 according to another embodiment of the invention, the front quarter 1102 whereof again has a first lateral guide 1111, arranged approximately longitudinally to said quarter 1102, and an upper quarter 1105. The upper quarter 1105 is arranged internally to the front quarter 1102 and is associated therewith by means of small pivots 1108a and 1108b passing through adapted holes 1109 and slideable at the second guide 1110, which is constituted for example by a slot provided a the same side of the first guide 1111. The seat 1112 is provided on said upper quarter 1105 at the first guide 1111 and, in the illustrated embodiment, has an essentially U-shaped configuration; the wings 1115a and 1115b whereof are directed towards the upper end 1106 or the lower end of said upper quarter 1105. Therefore, according to the position in which the stem 1113 of the slider 1114 is located, it is possible to achieve an adjustment not only of the degree of flexibility but also of the inclination of the upper quarter 1105. In fact, depending on whether the stem 1113 is positioned at the ends of the wings 1115a or 1115b, a given inclination is imparted to the upper quarter. If a single slider is used a tibial support adjustment is mainly achieved, while, as illustrated in figure 28, the actual inclination adjustment may be obtained by using a pair of sliders 1114a and 1114b, the stems 1113a, 1113b whereof slide within a pair of first guides 1111a, 1111b while a pair of seats 1112a, 1112b is provided on the upper quarter 1105. Figures 29 and 30 illustrate another embodiment, wherein the boot 1201 has again a front quarter 1202 and a rear quarter 1203 pivoted to a shell 1204; the upper quarter 1205 is downwardly provided with a pair of tabs 1216a and 1216b, laterally and externally embracing the shell 1204, being possibly but not necessarily associable therewith together with the front quarter. Laterally to the front quarter 1202 there is again a first guide 1211 arranged along an axis approximately parallel to the longitudinal one of said front quarter, holes 1209 being furthermore provided on the latter for small pins 1208a and 1208b, the first one whereof is slideable at an adapted second guide 1210 provided on said upper quarter 1205 at the side adjacent to the side of the front quarter which has the first guide 1211. On the upper quarter there is an L-shaped seat 1212 having wings directed towards the rear quarter 1203 and towards the upper end 1206 of said upper quarter. As in the embodiment illustrated in figures 21-24, the slider 1214 allows to adjust the flexibility with the advantage that the configuration of the upper quarter allows a certain elastic return of the front quarter during extension. Naturally the seat 1212 may also have a U-shaped configuration, as illustrated for the second variated aspect. In the embodiment illustrated in figures 31 and 32 a boot 1301 is composed of a front quarter 1302 and of a rear quarter 1303 pivoted to a shell 1304A with which the upper quarter 1305 is integrally associated. On at least one side, the upper quarter 1305 also has a second guide 1310 within which there may slide a first pin 1308a which passes, together with a second pin 1308b, at adapted holes 1309 provided laterally to the front quarter 1302 and on the upper quarter on the opposite side to the second guide 1310. A seat 1312, again having an L-shaped configuration, is furthermore provided, the first guide 1311 within which the slider 1314 may slide being provided at said seat on the front quarter 1302. This particular solution offers the advantage, with respect to the preceding ones, of eliminating a component, besides providing an elastic return of the front quarter 1302 during extension. The seat 1312 may also be U-shaped. Figures 33 and 34 illustrate a boot 1401 again constituted by a front quarter 1402 and by a rear quarter 1403 pivoted to a shell 1404. In this particular embodiment the upper quarter 1405 has a single tab 1416 downwardly protruding therefrom and acting as presser at the region 1417 of the skier's foot instep. On at least one side of the front quarter 1402 there is again a first guide 1411 arranged approximately parallel to the longitudinal axis of said rear quarter and at the underlying there is an L-shaped seat 1412. The upper quarter is associated with the front quarter by means of adapted pivots 1408a, 1408b passing at adapted holes 1409 provided on said rear quarter and on said upper quarter on the opposite side with respect to the second guide 1410. The second guide 1410 is provided on the upper quarter at the same side of the rear quarter in which the first guide 1411 is provided. Differently from the previously illustrated solutions, this allows to achieve a significant increase of the degree of securing of the instep of the foot during flexing. The seat 1412 may also have a U-shaped configuration. Figures 35, 36, 37 and 38 illustrate another embodiment of the device applied to a ski boot 1501 composed of a front quarter 1502 and for a rear quarter 1503 pivoted to a shell 1504. In this embodiment, the upper quarter 1505 is arranged externally to the front quarter 1502, at least at one side of the upper quarter there being provided a first guide 1511 arranged inclined with respect ot the longitudinal middle axis of the front quarter. The seat 1512 for the stem 1513 of the slider 1514 is instead provided on at least one side of the front quarter 1502 at the first guide 1511 provided on the upper quarter, and at least one first guide 1510 for pins according to what is illustrated in the first embodiment may also be provided. Said seat 1512 has a wing parallel to said first guide 1511 and the other one perpendicular thereto directed towards the slot 1507 provided on said front quarter 1502 thereof. On the opposite side to the seat 1512 the upper quarter 1505 and the front quarter 1502 have a hole 1509 for a small pivot 1508b. Similarly to the embodiment illustrated in figures 21-24, a pair of first guides 1511a, 1511b and, on the front quarter, a pair of eats 1512a, 1512b, for the sliding of the stems of a pair of sliders 1514a, 1514b, may be provided. Figures 39, 40, 41 and 42 illustrate a further embodiment of the device applied to a ski boot 1601 composed of a front quarter 1602 and of a rear quarter 1603 pivoted to a shell 1604. Similarly to the preceding embodiment, the upper quarter 1605 is external to the front quarter 1602, on the latter there being provided at least one U-shaped seat 1612, at the first guide 1611 of the upper quarter. The seat 1612, has wings 1615a and 1615b arranged inclined approximately in the direction of the upper end 1606 or of the lower one of the front quarter, and at least one first guide 1610 for pins, according to what is illustrated in the embodiment illustrated in figures 21-24, may also be provided. The use is similar to what has been previously illustrated and described, the positioning of the slider 1614 allowing to achieve an adjustment both of the flexibility and of the inclination of the upper quarter. In this case, too, it is naturally possible to provide, laterally to the front quarter 1602, a pair of seats 1612a and 1612b, together with a pair of first guides 1611a and 1611b, for the sliding of a pair of sliders 1614a and 1614b. Figure 43 illustrates a ski boot wherein the upper quarter 1705 is obtained by monolithic molding integrally with the front quarter 1702 and is jointed to said quarter in the central region 1706 which acts as hinge for the rotation of the upper quarter 1705. The boot furthermore has the seat 1712 for the slider 1714 similarly to what is described for the boot of figure 37. The boot of figures 44, 45, 46 has its upper quarter 2001 pivoted to the quarter 2002, at its lower part 2001a, for example by means of the elastically deformable tab 2001b inserted snap-together in the slot 2002a of the quarter (as illustrated in figure 45), or by means of a plate 2005 (as illustrated in figure 46). Laterally there is at least one slider 2003 adapted to vary the inclination of the upper quarter 2001 with respect to the quarter 2002 by means of the different arrangement of said slider on the guide 2004. The upper quarter 2001 of figures 44, 45 is external to the quarter 2002, while figure 46 illustrates an internal upper quarter; the illustrated boot is of the front-entry type, but it may also be of the rear-entry type. Figure 47 and 48 illustrate a boot wherein the upper quarter 2011 is integral with the shell 2006 and is arranged inside the quarter 2012; in this case, too, there is a slider 2003 adapted to vary the inclination of the upper quarter 2011 by means of its different positioning on the guide 2014. Figures 49-54 illustrate different further embodiments of the device, substantially similar to what is illustrated in the previously described figures 1-16. In this case (figures 49 and 50) the slider 3001 is connected to a small band 3002 so as to be arrangeable on one side of the boot. The band 3002 has in fact a tooth 3003 interacting with the abutment element 3004, while the slider 3001 is actuatable from outside of the boot by virtue of the presence of the slot 3005 on the quarter 3006. The device illustrated in figure 49 adjusts the flexing stroke of the quarter, while the device of figure 50 adjusts its inclination. Figures 51 and 52 illustrate a bilateral-action device wherein the slider 3011 has a tooth 3011a interacting with the abutment 3014a of the shell. The adjustment action occurs between the teeth 3011a, 3013 and, respectively, the abutments 3014a and 3104. Finally, figures 53 and 54 illustrate a device substantially similar to the one described in figure 49 but interacting between the upper quarter 3027 and the front quarter 3026. It has thus been observed that the device according to the invention achieves the intended aim and objects, allowing the adjustment of the flexibility in a simple and rapid manner on the part of the skier, who has to act with minimum effort.
