DETAILED DESCRIPTION

[0105] FIG. 1 shows an example embodiment of a heel retainer 100 comprising a brake device 1 for a sliding board binding or ski binding, in particular a binding with which the sliding board can be used in a touring mode and in a downhill mode.

[0106] The brake device 1 comprises a base 2, a pedal 4 and at least one brake element 3 which is pressed against the underlying surface, such as for example ice or snow, in order to slow the sliding board which has detached from the boot.

[0107] The base 2 comprises a connecting region 22 which exhibits a drill hole pattern 8 and which is arranged next to the pedal 4 in the longitudinal direction L of the brake device. The drill hole pattern 8 is designed such that it aligns with a drill hole pattern of the heel retainer 100 (not visible in FIG. 1), such that the brake device 1 and the heel retainer 100 can be jointly connected to the sliding board using the same fastening element 81.

[0108] In the example embodiment, the base 2 is slid onto a rail which can be connected to the sliding board or which is formed in part by the sliding board. The pedal 4 lies in front of or next to a heel jaw of the heel retainer 100 in the longitudinal direction L of the brake device.

[0109] The pedal 4 comprises a bearing area 41 featuring a surface 411. A functional element 5, a second ascending aid 7 and a latching element 6 (see FIG. 3), of which only the free end 611 is visible in FIG. 1, are connected to the pedal 4.

[0110] In the example embodiment, the functional element 5 and the second ascending aid 7 are mounted in the pedal 4 such that they can be moved in a common rotary joint D1 and can be pivoted relative to the pedal 4 in the rotary joint D1. The functional element 5 and the second ascending aid 7 can also be connected to the pedal 4 in separate rotary joints.

[0111] The functional element 5 comprises a first connecting arm 51 and a second connecting arm 52 which each comprise a first end 511, 521 and a second end. The second end of the first connecting arm 51 is connected to the pedal 4 in a first pivot joint, and the second end of the second connecting arm 52 is connected to the pedal 4 in a second pivot joint. The rotary joint D1 comprises the first pivot joint and the second pivot joint.

[0112] The first end 511 of the first connecting arm 51 and the first end 521 of the second connecting arm 52 are connected to each other by a transverse strut 53. The transverse strut 53 is rotatably mounted in the first connecting arm 51 and the second connecting arm 52 and/or can comprise a sleeve 10 which is rotatably mounted on the transverse strut 53. The transverse strut 53 can comprise a sheath made of a preferably elastic material such as for example plastic or rubber. The sleeve 10 can comprise a corresponding exterior layer or can be formed from the elastic material.

[0113] In the example embodiment, the second ascending aid 7 is U-shaped and comprises a first connecting arm 71, a second connecting arm 72 and a transverse strut 73 which connects the first connecting arm 71 and the second connecting arm 72 to each other. The first connecting arm 71 and the second connecting arm 72 each have a free end 711, 721, each of which comprises a drill hole 713 with which an axle of the rotary joint D1 engages. The first free end 711 forms a first abutting element or locking finger 712, and the second free end forms a second abutting element or locking finger 722. These abutting elements 712, 722 can be moved or pivoted in the rotary joint D1 up to a locking element or abutment 21. When abutting the abutment 21, the second ascending aid 7 is in the active position (see FIG. 10) with a height adjustment of about 10 in the example embodiment.

[0114] The second ascending aid 7 also comprises at least one grip 74 using which the second ascending aid 7 can be moved, by hand or by means of an implement such as for example the tip of a ski pole, from the resting position shown in FIG. 1 to the active position shown in FIG. 5 and back. The grip 74 can project laterally from one or both connecting arms 71, 72 and can be joined to the second ascending aid 7 or originally molded with the second ascending aid 7 in one piece, for example in a casting or die-casting method. The second ascending aid 7 can be manufactured from a metal or a plastic, preferably a reinforced plastic, or can comprise at least one of these materials.

[0115] FIG. 2 shows a lateral view of the heel retainer 100 and the brake device 1 of FIG. 1, wherein a boot 200 is indicated which is held in the heel jaw of the heel retainer 100 for descending on the sliding board.

[0116] The pedal 4 of the brake device 1 is shown, in which the rotary joint D1 is formed which connects the functional element 5 and the second ascending aid 7 to the pedal 4 such that they can be moved. Of the second ascending aid 7, the second connecting arm 72 comprising the grip 74 is shown. The ski boot 200 which is placed on the pedal 4 holds the brake elements 3 in the position shown, in which they cannot produce any braking effect for the sliding board. Also shown are the base 2 of the brake device 1 and a connecting element 81 which connects the heel retainer 100 and the brake device 1 to the sliding board in aligned drill hole patterns.

[0117] FIG. 3 shows a sectional view of FIG. 2 along or parallel to the longitudinal direction L of the brake device. This sectional view shows how the second ascending aid 7 is secured in the resting position on the pedal 4 in a positive fit and in a force fit, such that the ascending aid 7 cannot be independently moved from the resting position shown to the active position shown in FIG. 10. In the example embodiment, the pedal 4 comprises a stud 42 with which the transverse strut 73 can lock in order to secure the second ascending aid 7 in the resting position on the pedal 4.

[0118] The latching element 6 is mostly guided in the pedal 4 and participates in the movements of the pedal 4. The latching element 6 comprises a first arm 61 or main arm which extends substantially parallel to the surface 411 of the bearing area 41. The first arm 61 has a free end 611 which abuts the transverse strut 53 or the sleeve 10 of the functional element 5. A second arm 62 is formed at the end of the latching element 6 opposite the free end 611 and, in the example embodiment, protrudes substantially perpendicularly from the first arm 61 and forms an engaging element 64 at its free end 621 which protrudes through an opening 66 in the first position of the latching element 6 shown, such that the pedal 4 is free to be moved upwards, away from the sliding board, together with the latching element 6 when for example the sliding board detaches from the boot 200 in a fall.

[0119] In the example embodiment, the latching element 6 comprises a third arm 63 which serves as a support for a spring element or tensing element 9 which biases the latching element 6, shown in the first position, into the second position (see FIG. 9). The pedal 4 or, respectively, an abutting area for the spring element 9 in or on the pedal 4 forms another support for the spring element 9.

[0120] FIG. 4 shows the heel jaw of the heel retainer 100 in a release position in which the user can step out of the binding with their boot 200. The brake device 1 corresponds to the brake device 1 of the previously described figures and comprises the pedal 4, the brake elements 3, the functional element 5 and the second ascending aid 7. The functional element 5 and the second ascending aid 7 are connected to the pedal 4 in the rotary joint D1, such that the functional element 5 and the second ascending aid 7 can be moved relative to the pedal 4, out of the position shown.

[0121] The pedal 4, which is then free of any load, has been moved upwards in a direction away from an upper side of the sliding board by a known mechanism; the brake elements 3 have simultaneously been moved in the opposite direction. The brake device 1 or the mechanism comprises a complementary latching element 65 featuring an opening 66 in which the brake device 1 can be latched by means of the latching element 6 when the sliding board comprising the heel retainer 100 and the brake device 1 is used in the touring mode.

[0122] FIG. 5 shows a lateral view of FIG. 4, clearly showing the second arm 62 of the latching element 6 comprising the engaging element 64 to which the brake device 1 can be latched for use in the touring mode.

[0123] FIG. 6 shows a sectional view of FIG. 5. The brake device 1 comprises the functional element 5 featuring the transverse strut 53 and the sleeve 10. The second ascending aid 7 is secured against unintentionally detaching by the transverse strut 73 on a stud 42 which the pedal 4 comprises. The functional element 5 and the second ascending aid 7 are connected to the pedal 4 in the rotary joint D1. The free end 611 of the first arm 61 of the latching element 6 abuts the sleeve 10 of the functional element 5. The tensing element 9 tenses the latching element 6 in a direction away from the heel retainer 100, such that when it can be freely moved, the latching element 6 can be moved by the tensing element 9 from the first location shown to the second location shown in FIG. 9.

[0124] FIG. 7 shows the heel retainer 100 and the brake device 1, which is now secured in the touring mode, such that the load-relieved pedal 4 can no longer be moved into the position shown in FIG. 4. The functional element 5 has been moved from the first position, which it occupies in all the preceding figures, to a second position, such that the sleeve 10 is then arranged above the pedal 4 and above the bearing area 41. Unlike the example embodiment shown, the transverse strut 53 or the sleeve 10 can lie on the upper side 411 of the bearing area 41 in the second position. In this position, the functional element 5 forms a first ascending aid or walking aid, with a height adjustment of greater than or equal to 0 up to about 1, preferably up to about 2 to 3.

[0125] The front end 611 of the first arm 61 of the latching element 6 then protrudes further out of the pedal 4, which means that the tensing element 9 has moved the latching element 6 into the second location in which the engaging element 64 secures the brake device 1 in the opening 66. The position of the second ascending aid 7 is unchanged.

[0126] FIG. 8 shows a lateral view of FIG. 7 with a boot 200 indicated, a rear sole region of which is placed on top of the functional element 5. This view again shows how the transverse strut 53 of the functional element 5 or the sleeve 10 does not lie on the surface 411 of the bearing area 41 but is rather arranged above the surface 411, such that the transverse strut 53 and/or the sleeve 10 can be rotated if for example a distance between the boot 200 and the heel retainer 100 is briefly altered by the sliding board flexing.

[0127] The boot 200 is then arranged on the sliding board further forward than the heel retainer 100. Since, as already described, the brake device 1 and the heel retainer 100 are jointly connected to the sliding board in the same connection, this means that the boot 200 has been moved forwards relative to the sliding board, i.e. the sliding board binding comprises a front jaw (not shown) which can hold the front end of the boot 200 in two boot holding positions which are different from each other, namely a rear boot holding position for descending and a front boot holding position, which is different from the rear boot holding position, for alpine touring or for walking, i.e. as compared to the downhill position shown in FIG. 2, the boot 200 is situated further forward as viewed in the longitudinal direction L of the brake device, such that contact between the boot 200 and the heel jaw of the heel retainer 100 is prevented.

[0128] FIG. 9 also clearly shows how a front region of the first arm 61 of the latching element 6 comprises an elongated hole 67 through which the rotational axis D1 extends, such that the latching element 6 can be linearly moved relative to the rotational axis.

[0129] FIG. 9 shows a sectional view of FIG. 8, which clearly shows how the engaging element 64 of the latching element 6 protrudes through the opening 66 and has been moved away from the heel retainer 100 by the tensing element 9, such that the second arm 62 of the latching element 6 can now no longer be moved vertically, thus securely preventing the brake device 1 from being released.

[0130] The initial position for latching the brake device 1 is shown in FIG. 5. For the purpose of latching, the functional element 5 is then pivoted from the first location to the second location. The pedal 4 can be pressed onto the sliding board by hand or is preferably pressed onto the sliding board when the boot 200 is lowered. Since the engaging element 64 has already been moved into its end positionin which it can no longer pass through the opening 66by the tensing element 9, it is shaped at the free end 621 of the second arm 62 such that during the downward movement, the edge of the opening moves itagainst the force of the tensing element 9towards the heel retainer 100 until it can be pressed through the opening 66. Once the opening 66 has been penetrated, the latching element 6 is automatically moved by the tensing element 9 back into the blocked position shown in FIG. 9. In order to open this latching, the functional element 5 is moved from the second position shown back to the first position, wherein the functional element 5 presses the front end 611 of the first arm 61 of the latching element 6 towards the heel retainer 100, such that the engaging element 64 is arranged in such a way relative to the opening 66 that it can be moved through the opening 66 again. This unlatches the brake device 1 and moves the pedal 4 away from the surface of the sliding board.

[0131] FIG. 10 shows a brake device 1 in which the second ascending aid 7 has been moved into the active position and forms a height adjustment of about 10 in the example embodiment shown. The extent of the height adjustment is dependent on the length of the connecting arms 71, 72 and the shape of the transverse strut 73, which define a bearing point or bearing line for the boot 200.

[0132] FIG. 11 shows how the locking finger 722 of the second ascending aid 7 abuts the abutment 21. The weight of the boot 200 presses the second ascending aid 7 firmly against the abutment 21.

[0133] A locking element (not shown) can additionally be formed on the pedal 4, for example in the form of a partial sphere, which the locking finger or abutment 722 has to overcome before it can abut the abutment 21. It is thus possible to prevent the second ascending aid 7 from being moved out of the active position shown by the force of gravity alone and thus pressed onto the sliding board and into the resting position when the boot 200 is lowered. Aspects of the invention encompasses other known solutions which adequately solve this problem.

[0134] FIG. 12 shows a sectional view of FIG. 11.
