- the retaining wall 7 comprises a through opening 7 . 1 , such as a circular opening, the diameter of which is substantially smaller than the diameter of the collar 6 . 5 .
- a through opening 7 . 1 such as a circular opening, the diameter of which is substantially smaller than the diameter of the collar 6 . 5 .
- the retaining wall 7 is arranged so as to place the adjustment part 6 , when inserted into the retaining wall, in a position close to its location during use.
- This arrangement makes it possible to quickly fix the adjustment part.
- the adjustment part 6 is located in the vicinity of the end 52 . 2 of the portion 52 , close to the nut 52 . 11 .
- the retaining wall can form a tunnel through which a portion of the portion 53 passes. This tunnel makes it possible to guide the portion 53 translationally, and to keep it close to the second portion 52 .
- a first solution is to use a relatively flexible retaining wall 7 .
- the retaining wall 7 can thus deform elastically to be able to pass above the collar 6 . 5 and return to engage in the circular groove 6 . 4 .
- the more flexible the retaining wall 7 the less efficient the retention of the adjustment part 6 on the retaining wall 7 will be.
- a second solution is to make the collar 6 . 5 more flexible, for example by using a flexible and/or suitably collar-shaped material. In this case, it is the collar that will become deformed. This solution is suitable if the wall is relatively rigid. Conversely, this solution is ill-suited to the previous embodiment because it weakens the pressing surface 6 . 3 , which becomes deformed with the collar.
- a third solution is to locally slit the collar 6 . 5 .
- the slit 6 . 51 has a width “l” slightly greater than the thickness “e” of the wall 7 . It extends from the periphery of the collar 6 . 5 to substantially the bottom of the circular groove 6 . 4 . Thereafter, the engagement of a portion of the circular edge 7 . 2 of the opening 7 . 1 of the retaining wall 7 in the slit 6 . 51 makes it possible to guide the remainder of the circular edge 7 . 2 in the groove 6 . 4 . Indeed, a 360° rotation of the adjustment part 6 about its axis X 6 automatically brings the entire circular edge 7 . 2 in the circular groove 6 . 4 .
- the slit 6 . 51 is inclined at an angle ⁇ in relation to a plane perpendicular to the axis of rotation X 6 .
- the angle ⁇ is equal to 45°+/ ⁇ 10°.
- the angle ⁇ makes it possible to form a ramp 6 . 52 within the slit 6 . 51 . Consequently, when the adjustment part 6 is turned clockwise and a portion of the circular edge 7 . 2 is engaged in the slit, the ramp guides the circular edge 7 . 2 inward of the circular groove 6 . 4 .
- the same principle can be applied to dismount the adjustment part 6 from the retaining wall 7 , by turning the adjustment part 6 counterclockwise.
- This third solution can advantageously be combined with a flexible retaining wall 7 .
- the third portion 53 can be a simple tongue provided with a row of holes aligned along a longitudinal median line. These holes are adapted to receive the threaded rod 6 . 1 of the adjustment part 6 .
- the indexing device for positioning the second portion 52 in relation to the third portion 53 are formed by these holes and the threaded rod.
- the invention can also apply to an element for adjusting the abutment of a rear support element, or highback, such as described, for example, in EP-A-1 108 450 and in U.S. Pat. No. 6,533,295-B2, the disclosure of the latter being hereby incorporated by reference thereto in its entirety.

The retaining or tightening linkage/strap is generally divided into three portions, namely, a first portion connected to the base; a second portion, namely, a so-called covering portion for covering a portion of the foot; and a third portion, also connected to the base. The position of the covering portion is adjustable in relation to the first portion, as it is adjustable in relation to the third portion. These adjustments make it possible to correctly position the covering portion, which is adapted to be in contact with the foot or boot of the rider. This correct positioning makes it comfortable to wear the boot. The first positional adjustment for the second portion, in relation to the first portion, involves a ratchet mechanism. During use, this is the area in which the linkage opens whenever the user wishes to insert or remove the boot into/from the binding. The first adjustment mechanism should therefore be strong and easy to operate. It is quite complex and expensive. Conversely, the second positional adjustment for the second portion, in relation to the third portion, generally does not change much during use. The adjustment is made once to adapt to the boot. The second adjustment mechanism should be reliable but can be simplified to be less expensive. An embodiment of the second adjustment mechanism involves using a screw that is fixed on the covering portion and passes through the third portion. This embodiment is very simple and inexpensive but has a drawback that the screw, once disengaged, may be dropped and lost.

second portion 52, or covering portion, extends along its length from a first end 52.1 to a second end 52.2, transversely from a first edge 52.3 to a second edge 52.4, and thickness-wise from a support surface 52.5 to a free surface 52.6. The support surface 52.5 is adapted to press against the rider's foot or boot. In addition, as can be seen in the drawing figures, the length of the portions of the linkage/strap extends across or transversely in relation to the longitudinal direction of the retainingdevice 1. - With particular reference to
FIG. 2 , the coveringportion 52 comprises a frame 52.7, which is substantially lengthwise inextensible to provide a stable tightening of the foot or boot, and it is also transversely, or widthwise, flexible so as to make it possible to adapt it to the shape or surface(s) of the foot or boot. As shown inFIG. 4 , the frame 52.7 is partially coated with a foam 52.8, at least in the area of the support surface 52.5 in order to provide comfort to the rider. The frame 52.7 and foam 52.8 are inserted into a cover 52.9. (SeeFIGS. 2-4 .) - The
third portion 53 extends along its length between a fastening end 53.1 and a free end 53.2. The fastening end 53.1 is affixed to themedial flange 22, for example, by means of a pivot or articulation 53.3. Here again, the pivot 53.3 may include any element, such as a screw, a bolt/nut, a rivet, or other such mechanical element or assembly. - The first 51 and second 52 portions are removably connected, i.e., they are readily separable.
- The second 52 and third 53 portions are connected so as to form a
section 54 having a length that does not vary much during use, except for adjusting the linkage/strap 5 to the footwear. The purpose of this adjustment is to properly balance the position of thesecond portion 52 in the area of the instep. - In this embodiment, the connection between the first 51 and second 52 portions is carried out by a tightening ratchet mechanism 52.10. This mechanism 52.10 is affixed to the frame 52.7, in the area of the second end 52.1 of the
second portion 52. Thefirst portion 51 comprises a series of teeth 51.4 oriented outward. These teeth 51.4 are spread from the free end 51.2 to the vicinity of the hinge 51.3. The teeth 51.4 cooperate with the ratchet to block the linkage/strap 5 at a predetermined tightening length. The free end 51.2 of thefirst portion 51 passes above or through a tunnel or passageway of thesecond portion 52. - The
section 54 is adjustable lengthwise to adjust the positioning of thesecond portion 52. For this, the adjustment is carried out by means of the following elements. - The
third portion 53, forming a tongue, comprises a series of inwardly projecting teeth 53.4 (seeFIG. 4 ) and a longitudinal groove 53.5 (seeFIGS. 1 and 4 ) centered along the tongue. The teeth 53.4 are spread from the free end 53.2 to the vicinity of the hinge 53.3. The longitudinal groove 53.5 extends over a similar length. - The end 52.2 of the
second portion 52 is also fitted. A nut 52.11 is fixed on the frame 52.7 so that its axis of revolution X11 passes through the median and transverse planes of thesecond portion 52. Two studs 52.71, 52.72 extend outward along a longitudinal direction, on both sides of the nut 52.11. The two studs 52.71, 52.72 are structured and arranged to be housed in the longitudinal groove 53.5 so as to position and translationally guide thethird portion 53 with respect to thesecond portion 52. Moreover, a series of teeth 52.73, outwardly projecting, are spread on both side of a zone including the two studs 52.71, 52.72, along a transverse direction. The teeth 52.73 are sized to cooperate with the teeth 53.4 of thethird portion 53, when thethird portion 53 is brought closer to thesecond portion 52, thereby immobilizing thethird portion 53 with respect to thesecond portion 52. - Finally, an
adjustment part 6, or manipulatable part, rotatable about an axis X6, comprises a threaded rod 6.1 centered on that axis. The threaded rod 6.1 is structured and arranged to engage the nut 52.11 and to pass through the longitudinal groove 53.5. Theadjustment part 6 comprises an interface 6.2 structured and arranged for engagement and manipulation by a user, such as the rider. Theadjustment part 6 also comprises a lower pressing surface 6.3, perpendicular to the axis X6 and positioned at the base of the threaded rod 6.1. The pressing surface 6.3 is wider than the width of the longitudinal groove 53.5. In the illustrated embodiment, the threaded rod 6.1, the pressing surface 6.3, in conjunction with the nut 52.11 can be regarded as a mechanism for enabling the teeth 53.4 of thethird portion 53 to cooperate with the teeth 52.73 of thefirst portion 52 of thesports article 1. - Thus, the pressing surface 6.3 moves closer to the
second portion 52 when theadjustment part 6 is screwed into the nut 52.11. The pressing surface 6.3 then comes into contact with an outer surface 53.6 of thetongue 53, i.e., the surface opposite the teeth 53.4. Consequently, as theadjustment part 6 is continued to be turned, the pressing surface 6.3 exerts a force on thethird portion 53 that tends to bring it closer to thesecond portion 52. The teeth 53.4 then engage the teeth 52.73, thereby affixing the second 52 and third 53 portions forming thesection 54. - The teeth 53.4 and 52.73 form indexing device in the context of the invention. Other indexing devices, such as one or more pins cooperating with a row of holes, are within the scope of the invention.
- To adjust the length of the
section 54, first theadjustment part 6 is unscrewed until the teeth 53.4 are no longer engaged with the teeth 52.73. Second, thesecond portion 52 is displaced in relation to thethird portion 53 until the desired length for thesection 54 is obtained. This displacement is guided by the studs 52.71, 52.72 cooperating with the longitudinal groove 53.5. Third, theadjustment part 6 is again screwed so that the teeth 53.4 and 52.73 are again engaged. - During the first step, there is a risk of losing the
adjustment part 6, if completely unscrewed. To overcome this drawback, theadjustment part 6 is connected to aretaining wall 7 affixed to the sports article. In this example, the retainingwall 7 is integral with the cover 52.9 covering the end 52.1 of thesecond portion 52, on the outer side. - To connect the
adjustment part 6 to theretaining wall 7, theadjustment part 6 has a circular groove 6.4 for receiving a portion of aretaining wall 7. This groove is demarcated on one side by the manipulation interface 6.2 and, on the other side, by a collar 6.5, such as a collar having a disc shape. The threaded rod 6.1 projects from the collar 6.5. The pressing surface 6.3 is formed by the lower surface of the collar 6.5, on the side of the threaded rod 6.1. - The retaining
wall 7 comprises a through opening 7.1, such as a circular opening, the diameter of which is substantially smaller than the diameter of the collar 6.5. Thus, when theadjustment part 6 is inserted through the opening 7.1 of theretaining wall 7, the circular edge 7.2 of the opening becomes housed in the circular groove 6.4. Theadjustment part 6 is thus retained on theretaining wall 7 and cannot easily be dismounted. - Advantageously, the retaining
wall 7 is arranged so as to place theadjustment part 6, when inserted into the retaining wall, in a position close to its location during use. This arrangement makes it possible to quickly fix the adjustment part. In this case, theadjustment part 6 is located in the vicinity of the end 52.2 of theportion 52, close to the nut 52.11. - Similarly, the retaining wall can form a tunnel through which a portion of the
portion 53 passes. This tunnel makes it possible to guide theportion 53 translationally, and to keep it close to thesecond portion 52. - Several solutions are within the scope of the invention to facilitate the positioning of the
adjustment part 6 on theretaining wall 7. - A first solution is to use a relatively
flexible retaining wall 7. The retainingwall 7 can thus deform elastically to be able to pass above the collar 6.5 and return to engage in the circular groove 6.4. The more flexible theretaining wall 7, the less efficient the retention of theadjustment part 6 on theretaining wall 7 will be. - A second solution is to make the collar 6.5 more flexible, for example by using a flexible and/or suitably collar-shaped material. In this case, it is the collar that will become deformed. This solution is suitable if the wall is relatively rigid. Conversely, this solution is ill-suited to the previous embodiment because it weakens the pressing surface 6.3, which becomes deformed with the collar.
- A third solution is to locally slit the collar 6.5. The slit 6.51 has a width “l” slightly greater than the thickness “e” of the
wall 7. It extends from the periphery of the collar 6.5 to substantially the bottom of the circular groove 6.4. Thereafter, the engagement of a portion of the circular edge 7.2 of the opening 7.1 of theretaining wall 7 in the slit 6.51 makes it possible to guide the remainder of the circular edge 7.2 in the groove 6.4. Indeed, a 360° rotation of theadjustment part 6 about its axis X6 automatically brings the entire circular edge 7.2 in the circular groove 6.4. - Advantageously, the slit 6.51 is inclined at an angle α in relation to a plane perpendicular to the axis of rotation X6. In a particular embodiment, the angle α is equal to 45°+/−10°. The angle α makes it possible to form a ramp 6.52 within the slit 6.51. Consequently, when the
adjustment part 6 is turned clockwise and a portion of the circular edge 7.2 is engaged in the slit, the ramp guides the circular edge 7.2 inward of the circular groove 6.4. The same principle can be applied to dismount theadjustment part 6 from the retainingwall 7, by turning theadjustment part 6 counterclockwise. - This third solution can advantageously be combined with a
flexible retaining wall 7. - The invention is not limited to the embodiments described above.
- It is in particular applicable to other embodiments for the lengthwise adjustment of the
portion 54. For example, thethird portion 53 can be a simple tongue provided with a row of holes aligned along a longitudinal median line. These holes are adapted to receive the threaded rod 6.1 of theadjustment part 6. Thus, the indexing device for positioning thesecond portion 52 in relation to thethird portion 53 are formed by these holes and the threaded rod. - The invention can also apply to an element for adjusting the abutment of a rear support element, or highback, such as described, for example, in EP-A-1 108 450 and in U.S. Pat. No. 6,533,295-B2, the disclosure of the latter being hereby incorporated by reference thereto in its entirety.
- The scope of the invention also encompasses a part for adjusting a ski boot or a ski binding.
- At least because the invention is disclosed herein in a manner that enables one to make and use it, by virtue of the disclosure of particular exemplary embodiments of the invention, the invention can be practiced in the absence of any additional element or additional structure that is not specifically disclosed herein.
