Definitions
- the present invention relates to a device for adjusting the position of a quarter with respect to the shell of a sports shoe.
- Conventional ski boots for example, are provided with a shell to which at least one quarter is articulated approximately at the malleolar region.
- the quarter is allowed to oscillate forwards and backwards during sports practice.
- a problem that is currently dealt with in the manufacture of ski boots is the possibility to control the oscillation of the quarter according to the specific sport or to any walking that the skier may have to do after disconnecting the boots from the skis.
- FR-A-2,647,649 discloses a ski boot constituted by a shell to which a quarter is articulated which comprises a tilting element which co-operates with a locator which is rigidly coupled to the shell in order to arrange the quarter in a chosen inclined position with respect to the shell.
- the shoe also comprises adjustable means which co-operate with the locator in order to modify the static inclination of the quarter of the shoe.
- the adjustable means is constituted by a locator which can be moved by means of a screw and can be accessed by the user.
- the actuation of the screw allows to vary the point where backward rotation is blocked for the quarter and therefore to vary its forward inclination.
- the tilting element can be activated manually by the user so that it does not interact with the locator, thus allowing optimum free backward movement of the quarter in the walking mode.
- This mode is not very easy for the user, because achieving it entails simultaneously imparting a manual movement to the tilting element in order to move it away from the locator and a backward movement of the leg in order to prevent interaction with the locator.
- the free movement of the quarter is limited by the tilting element, which can catch on or encounter obstacles between the support and the shell.
- the above-described boot also allows only one single position during sports practice, namely one allowing free forward movement, the boot however is not adapted for all sports, such as for example slalom, downhill racing or mountain skiing.
- E-P-A 0582803 discloses a mountain-skiing boot which comprises a shell to which a quarter is articulated so as to be able to oscillate.
- An eccentric element is rotatably associated with the quarter and interacts with a lever which is transversely articulated to the quarter and oscillates in contrast with a spring the other end whereof interacts with the quarter.
- the end of the lever that interacts with the spring can be arranged in abutment at an adapted recess provided in the shell.
- the articulation axis of the lever can be shifted vertically; this allows greater freedom of movement of the quarter and easier actuation of the device with respect to the previous solution, but still has the drawback that it allows free forward movement of the quarter and therefore does not allow to lock said quarter. As in the previously described boot, this is not ideal for the various kinds of skiing that can be performed.
- EPA No. 95108268.4 discloses a device for adjusting the position of a quarter with respect to the shell of a sports shoe, which comprises a lever which can be actuated by the user.
- the position of the lever with respect to adapted tabs, springs and a toothed ring allows to block the oscillation of the quarter or to achieve its free oscillation when the quarter is flexed forwards and the free backward oscillation of the quarter for walking.
- this boot is constructively very complicated, because it requires interaction among many components in order to achieve the chosen setting. Furthermore, if the user has preset a skiing position, thus either allowing the quarter to flex forwards or locking it, said position could not be kept “memorized” after selecting the condition for walking, making it necessary to set again either the locking of the quarter or the free forward flexing thereof.
- EPA No. 95108268.4 discloses a device for adjusting the position of a quarter with respect to the shell of a sports shoe which comprises a knob, rotation of which entails an equal rotation of a plate and of an eccentric element which loads a spring which actuates the positioning of a tilting element, moving it closer or further away from the shell.
- This boot allows to choose between the walking position and the skiing position, as required, at any time during sports practice, since the energy applied by the user to the eccentric element is accumulated by the spring, which forces the tilting element until it reaches a stable condition, allowing the quarter to assume an inclined skiing position and oscillate freely forwards, or a walking position, allowing free forward and backward oscillation.
- this device allows to achieve a single position for skiing which is preset by the manufacturer and therefore cannot be customized by the user in any way, at the same time allowing free oscillation of the quarter in a backward direction.
- this boot does not allow complete forward and backward locking of the quarter with respect to the shell.
- the aim of the present invention is therefore to solve the problems described above, eliminating the drawbacks of the prior art by providing a device which allows to achieve an adjustment of the position of a quarter with respect to the shell of a sports shoe while storing the positions selected by the user.
- An important object is to provide a device which is compact with respect to conventional devices.
- a further important object is to provide a device which is structurally more simple and therefore has low manufacturing costs.
- Still a further important object is to provide a device whose actuation and operation are simple and intuitive for the user.
- Still a further object is to provide a device which combines the above characteristics together with that of being reliable and safe in use and of being producible with conventional machines and equipment.
- a device for adjusting the position of a quarter with respect to the shell of a sports shoe characterized in that it comprises a base element associated with a first actuation element for selecting either an active position, in which the backward oscillation of said quarter with respect to said shell is blocked, or an inactive position, in which said backward oscillation is free, a second actuation element, being associated with said base element, said second actuation element being distinct and separate from said first element and being adapted to select either a first configuration of said active position, in which the forward oscillation of said quarter with respect to said shell is blocked, and a second configuration of said active position, in which said forward oscillation is free.
- the reference numeral 1 designates the device for adjusting the position of a quarter 2 with respect to the shell 3 of a sports shoe such as, for example, a ski boot or a skate.
- the device is preferably applied at the rear region of the quarter 2 and is substantially constituted by a base element 4 which, at the surface that faces the quarter 2, has first lateral guides 5a, 5b for complementarily shaped first tabs 6a, 6b which are provided at the ends of a slider 7 whose cross-section is substantially U-shaped with an axial ridge 9 at the first base 8.

- the movement of the slider 7 forces a downward movement of the end of the second spring 27 accommodated in the inclined cavity 28, which in turn forces the oscillation of the pawl 15 and therefore the approach or arrangement of its first end 24, which is hook-shaped, at an adapted opening 29 formed on a plate 30 which is rigidly coupled to the shell 3 or is formed directly on said shell 3.

Abstract
Description
- The present invention relates to a device for adjusting the position of a quarter with respect to the shell of a sports shoe.
- Conventional ski boots, for example, are provided with a shell to which at least one quarter is articulated approximately at the malleolar region. The quarter is allowed to oscillate forwards and backwards during sports practice.
- A problem that is currently dealt with in the manufacture of ski boots is the possibility to control the oscillation of the quarter according to the specific sport or to any walking that the skier may have to do after disconnecting the boots from the skis.
- In this regard, FR-A-2,647,649 discloses a ski boot constituted by a shell to which a quarter is articulated which comprises a tilting element which co-operates with a locator which is rigidly coupled to the shell in order to arrange the quarter in a chosen inclined position with respect to the shell.
- The shoe also comprises adjustable means which co-operate with the locator in order to modify the static inclination of the quarter of the shoe. The adjustable means is constituted by a locator which can be moved by means of a screw and can be accessed by the user.
- The actuation of the screw allows to vary the point where backward rotation is blocked for the quarter and therefore to vary its forward inclination.
- The tilting element can be activated manually by the user so that it does not interact with the locator, thus allowing optimum free backward movement of the quarter in the walking mode.
- This mode, however, is not very easy for the user, because achieving it entails simultaneously imparting a manual movement to the tilting element in order to move it away from the locator and a backward movement of the leg in order to prevent interaction with the locator.
- Furthermore, in the walking mode the free movement of the quarter is limited by the tilting element, which can catch on or encounter obstacles between the support and the shell.
- The above-described boot also allows only one single position during sports practice, namely one allowing free forward movement, the boot however is not adapted for all sports, such as for example slalom, downhill racing or mountain skiing.
- E-P-A 0582803 discloses a mountain-skiing boot which comprises a shell to which a quarter is articulated so as to be able to oscillate. An eccentric element is rotatably associated with the quarter and interacts with a lever which is transversely articulated to the quarter and oscillates in contrast with a spring the other end whereof interacts with the quarter.
- The end of the lever that interacts with the spring can be arranged in abutment at an adapted recess provided in the shell.
- The articulation axis of the lever can be shifted vertically; this allows greater freedom of movement of the quarter and easier actuation of the device with respect to the previous solution, but still has the drawback that it allows free forward movement of the quarter and therefore does not allow to lock said quarter. As in the previously described boot, this is not ideal for the various kinds of skiing that can be performed.
- EPA No. 95108268.4 discloses a device for adjusting the position of a quarter with respect to the shell of a sports shoe, which comprises a lever which can be actuated by the user. The position of the lever with respect to adapted tabs, springs and a toothed ring allows to block the oscillation of the quarter or to achieve its free oscillation when the quarter is flexed forwards and the free backward oscillation of the quarter for walking.
- However, this boot is constructively very complicated, because it requires interaction among many components in order to achieve the chosen setting. Furthermore, if the user has preset a skiing position, thus either allowing the quarter to flex forwards or locking it, said position could not be kept "memorized" after selecting the condition for walking, making it necessary to set again either the locking of the quarter or the free forward flexing thereof.
- EPA No. 95108268.4 discloses a device for adjusting the position of a quarter with respect to the shell of a sports shoe which comprises a knob, rotation of which entails an equal rotation of a plate and of an eccentric element which loads a spring which actuates the positioning of a tilting element, moving it closer or further away from the shell.
- This boot allows to choose between the walking position and the skiing position, as required, at any time during sports practice, since the energy applied by the user to the eccentric element is accumulated by the spring, which forces the tilting element until it reaches a stable condition, allowing the quarter to assume an inclined skiing position and oscillate freely forwards, or a walking position, allowing free forward and backward oscillation.
- As in the boot disclosed in patent EP-A-0582803, this device allows to achieve a single position for skiing which is preset by the manufacturer and therefore cannot be customized by the user in any way, at the same time allowing free oscillation of the quarter in a backward direction.
- Accordingly, this boot does not allow complete forward and backward locking of the quarter with respect to the shell.
- The aim of the present invention is therefore to solve the problems described above, eliminating the drawbacks of the prior art by providing a device which allows to achieve an adjustment of the position of a quarter with respect to the shell of a sports shoe while storing the positions selected by the user.
- An important object is to provide a device which is compact with respect to conventional devices.
- A further important object is to provide a device which is structurally more simple and therefore has low manufacturing costs.
- Still a further important object is to provide a device whose actuation and operation are simple and intuitive for the user.
- Still a further object is to provide a device which combines the above characteristics together with that of being reliable and safe in use and of being producible with conventional machines and equipment.
- This aim, these objects and others which will become apparent hereinafter are achieved by a device for adjusting the position of a quarter with respect to the shell of a sports shoe, characterized in that it comprises a base element associated with a first actuation element for selecting either an active position, in which the backward oscillation of said quarter with respect to said shell is blocked, or an inactive position, in which said backward oscillation is free, a second actuation element, being associated with said base element, said second actuation element being distinct and separate from said first element and being adapted to select either a first configuration of said active position, in which the forward oscillation of said quarter with respect to said shell is blocked, and a second configuration of said active position, in which said forward oscillation is free.
- Further characteristics and advantages of the invention will become apparent from the detailed description of a particular but not exclusive embodiment, illustrated only by way of nonlimitative example in the accompanying drawings, wherein:
- Fig. 1 is an exploded view of the device;
- Fig. 2 is a plan view of the device;
- Fig. 3 is a sectional view, taken along the plane III-III of Fig. 2;
- Fig. 4 is a sectional view, taken along the plane IV-IV of Fig. 2;
- Figs. 5, 6 and 7 are views, similar to Figs. 2, 3 and 4, of a different arrangement of the device;
- Figs. 8, 9 and 10 are views, similar to Figs. 2, 3 and 4, of another different arrangement of the device;
- Figs. 11, 12 and 13 are views, similar to Figs. 2, 3 and 4, of another different arrangement of the device.
-
- With reference to the above figures, the reference numeral 1 designates the device for adjusting the position of a
quarter 2 with respect to theshell 3 of a sports shoe such as, for example, a ski boot or a skate. - The device is preferably applied at the rear region of the
quarter 2 and is substantially constituted by abase element 4 which, at the surface that faces thequarter 2, has first lateral guides 5a, 5b for complementarily shaped first tabs 6a, 6b which are provided at the ends of aslider 7 whose cross-section is substantially U-shaped with an axial ridge 9 at the first base 8. - The
slider 7 can therefore be slidingly associated at the end 10 of thebase element 4 that is directed away from the ground or the snow. - A first seat 11 for a tilting
element 12 is formed in theshell 4. The tilting element can be arranged thereat and is substantially U-shaped, and a secondaxial seat 14 for apawl 15 is formed between the wings 13a, 13b of the tilting element. - The tilting
element 12 is pivoted transversely to thebase element 4, along a first axis B, by means of afirst pivot 16, which passes at first holes 17a and 17b formed on the shoulders 18a and 18b of thebase element 4, between which the first seat 11 is formed, and at second holes 19 which are formed proximate to the tips of the wings 13a and 13b of thetilting element 12. - The
pawl 15 is in turn pivoted between the wings 13a and 13b by means of an adaptedsecond pivot 20. - The
pawl 15 is arranged within the secondaxial seat 14 and is forced into this position by afirst torsion spring 21 which is accommodated at an adapted third seat 22 which is formed on one of said wings 13a, 13b and is arranged coaxially to thesecond pivot 20. Thefirst spring 21 has an end which interacts with the back 23 of thepawl 15. - The pawl has a
first end 24 which is directed towards the snow and forms a hook directed toward theshell 3. - The
pawl 15 has a second end 25 at the opposite end. Second end 25 has afourth seat 26 for the end of an elastic means for the selective interaction of said pawl with said shell. The elastic means is constituted by asecond torsion spring 27, having a second end interacting in abutment at aninclined cavity 28 formed on the ridge 9 of theslider 7 at the end that is directed toward thetilting element 12. Theinclined cavity 28 is blended with the first base 8 of saidslider 7. - As shown for example in Figs. 3 and 6, the movement of the
slider 7 forces a downward movement of the end of thesecond spring 27 accommodated in theinclined cavity 28, which in turn forces the oscillation of thepawl 15 and therefore the approach or arrangement of itsfirst end 24, which is hook-shaped, at an adaptedopening 29 formed on aplate 30 which is rigidly coupled to theshell 3 or is formed directly onsaid shell 3. - The sliding of the
slider 7 with respect to thebase element 4 is guided by an adaptedthird spring 21 which is axially associated with thebase element 4 and protrudes from it toward theslider 7. Thethird spring 31 is a thin plate provided with a transverse ridge 32 for temporary engagement with a complementarily shaped fifth seat 33 formed on the ridge 9 at the opposite end with respect to the one provided with theinclined cavity 28. - The fifth seat 33 and said transverse ridge 32 allow to arrange the
slider 7 in a temporary and stable position with respect to thebase element 4. - The
slider 7 also has at least onesecond guide 34, at the first base 8 and at the opposite side with respect to thebase element 4. Asecond tab 35 is slidingly arranged in thesecond guide 34 and is associated with thequarter 2 or with thebase element 4. - The device 1 is also constituted by an
eccentric element 36 arranged within the first seat 11 of thebase element 4. Theeccentric element 36 has a first axial stem 37 which forms a second axis A and protrudes outside the shoulder 18a of thebase element 4 through an adapted third hole 38 formed therein. Aknob 39 can be keyed to saidfirst stem 36 and 37 and is accordingly arranged laterally to the shoulder 18b and can be easily gripped by the user. - The
eccentric element 36 also has a second stem 40 which is axially offset and faces the wing 13a of theadjacent tilting element 12. The end of an elastic means, such as afourth traction spring 41, is associated coaxially with the second stem. The spring is associated, at its other end, with a third pivot 42 which protrudes from the wing 13a of the tiltingelement 12. - A thinner region is formed in said wing 13a in order to allow to accommodate the
eccentric element 36 and thefourth spring 41. - Before describing the operation, it should be noted that the terms "WALK" or "inactive position" designate a condition of the device which allows the user to walk, while the expression "active position" designates the state of the device that allows to ski.
- Furthermore, within the active position, the term "SLALOM" or "first configuration" designates a condition of the device which blocks any forward and backward movement of the quarter, while the term "CARVE" or "second configuration" designates a condition for the device in which the quarter can oscillate freely forwards.
- Assuming that the initial position allowed by the device is the one designated as WALK or inactive, and therefore the position for walking, the skier can select one of two distinct configurations of the active position in order to ski; this is done by moving the
slider 7 vertically and turning theknob 39 through 180°. - The walking position is illustrated in Figs. 2 to 6: in this position, the tilting
element 12 is moved backwards with respect to theshell 3, so as to allow free forward and backward oscillation of the quarter with respect to the shell. - If the skier wishes to pass to the active skiing condition, he can for example turn the
knob 39 through 180°, as shown in Figs. 9 to 13. - This rotation forces an equal rotation of the
eccentric element 36 which is connected to thefourth spring 41, which moves the tiltingelement 12, forcing it to rotate so that thesecond base 43 of the tiltingelement 12 that connects the wings 13a and 13b is arranged adjacent to anabutment 44 formed at the facing surface of theshell 3. - Any backward oscillation of the quarter is therefore contrasted by the tilting
element 12, because thesecond base 43 thereof rests in abutment against thelocator 44. - It is evident that in passing from the inactive position to the active position the device maintains the configuration of the active position that had been set earlier.
- Figs. 5 to 10 in fact show that the
slider 7 is shifted downwards toward the ground with respect to thebase element 4, thus determining the first configuration ("SLALOM") of the device. Thesecond spring 27 in fact forces thepawl 15 to oscillate so that itsfirst end 24, which is hook-shaped, tends to protrude from the secondaxial seat 14 formed on the tiltingelement 12, thus overcoming the force of thefirst spring 21. - If the user turns the
knob 39 through 180°, the knob forces the oscillation of the tilting element as mentioned earlier, making thesecond base 43 abut again against thelocator 44 provided on theshell 3 and simultaneously allows to arrange the first hook-shapedend 24 of thepawl 15 at theopening 29 formed in theplate 30 or directly in theshell 3. - In this way, the
pawl 15 prevents any forward oscillation of the quarter and the tiltingelement 12 prevents any backward rotation of the quarter. - As in the preceding case, the simple rotation of the
knob 39 allows the user to reposition the quarter in the WALK position for walking and vice-versa because the device maintains the configuration for the previously selected type of skiing. - If one wishes to pass from the first configuration to the second configuration while remaining in the active position, as shown in Figs. 8 to 13, it is sufficient for the user to move the
slider 7 upwards, thus obtaining the second configuration ("CARVE"). The upward sliding of theslider 7 in fact produces a counterclockwise rotation of thesecond spring 27 and in particular lifts its lower end, which is connected to thepawl 15, forcing the oscillation of said pawl in a clockwise direction, making thefirst end 24 disengage from theopening 29. The quarter is therefore allowed to oscillate freely forwards, while the backward oscillation is still blocked by the tiltingelement 12. - In passing from the second configuration of the active position to the inactive position the set configuration is maintained also in this case because the position of the
pawl 15 is not altered, as shown in Figs. 11 to 13 and 2 to 4. - Therefore, the device memorizes the different configurations set in the active position when passing to the "WALK" position or inactive position. As shown in Figs. 2, 3 and 4, the
pawl 15 is in fact fully accommodated within the secondaxial seat 14 formed in the tiltingelement 12, as shown in Figs. 11, 12 and 13, while as shown in Figs. 5, 6 and 7 thepawl 15 is slightly rotated and therefore its first hook-shapedend 24 protrudes slightly from the secondaxial seat 14, as shown in Figs. 8, 9 and 10. - It has thus been observed that the invention has achieved the intended aim and objects, a device having been provided which makes it easier and more comfortable for the user to position the quarter with respect to the shell, remembering the selected operating positions and decreasing the dimensions, the bulk and the production costs.
- The device in fact allows to achieve multiple configurations in the active skiing position and allows to select at any time the walking position while the preceding skiing configuration used continues to be preset and therefore "memorized" and is automatically restored when the walking position is abandoned.
- Furthermore, the components of the device are all grouped within the
base element 4 and accordingly the device is compact. - Furthermore, the device is intuitive in terms of operation for the user, making it even easier to use.
- The device according to the invention is of course susceptible of numerous modifications and variations, within the scope of the appended claims.
- The materials and the dimensions that constitute the individual components of the device may also be the most pertinent according to the specific requirements.
- The disclosures in Italian Patent Application No. TV97A000162 from which this application claims priority are incorporated herein by reference.
- Where technical features mentioned in any claim are followed by reference signs, those reference signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly, such reference signs do not have any limiting effect on the interpretation of each element identified by way of example by such reference signs.
