Description

Device for retaining a shoe on a gliding board and sliding device comprising such a device

The present invention relates to a device for retaining a boot on a gliding board as well as a gliding device comprising a gliding board, such as a cross-country ski or touring ski equipped with said retaining device. Such a retaining device is sometimes called "stop", "front stop" or "fixing".

Within the meaning of the present invention, a gliding device is a material on which a person stands when using this device for the practice of a sliding sport, by being hooked by at least one of his shoes on this craft.

In the field of sliding sports, more particularly in the field of cross-country skiing, it is advantageous to be able to adjust the longitudinal position of the skier's shoe along the ski.

In the case of classic or alternative cross-country skiing, the ski is arched and defines, under the boot, an area which, by default, is not in contact with snow. This area constitutes a "wax chamber". In this area, you can add grip wax so as to increase the grip of the ski on snow in order to prevent the ski from rolling back, which makes it possible to exert an effective push with the foot. By modifying the longitudinal position of a boot retention device on the ski, it is possible to adjust the contact area between the ski and the snow according to the weight exerted by the skier, by favoring sliding or grip. When cornering, the skier has to lift a ski to bring it back to the other ski. In this phase, the lifted ski is connected to the skier only by the front end of the boot and it is important that the ski is properly balanced. If the ski leans forwards or backwards, it can touch the snow, which can slow the skier or make him unbalanced. The length adjustment of a boot retainer on the ski therefore makes it possible to adjust the balance of the ski in this raised configuration.

In the case of a skating ski, there is a similar problem of balance when the ski is lifted to be brought to the other ski in the so-called aerial phases. In addition, when the snow is sticky, the skier may wish a slight imbalance towards the back of his skis to raise the front tip by default and thus limit the risk of planting this tip in the snow during progression on the track. These adjustment possibilities for a skating ski are also obtained by adjusting the longitudinal position of the boot retainer on the ski.

The adjustment of the longitudinal position of a binding on a cross-country ski has been described in several patent applications. This function has also been integrated into certain market fixings.

For example, document WO-A-2005/113081 describes notches on elastically deformable tongues of a device for retaining a cross-country ski boot, these notches being intended to cooperate with complementary notches formed on a ski. The longitudinal immobilization of the retainer along the ski depends on the stiffness of the tongues. In addition, inadvertent catching of one or the other of the tongues can disengage the retainer from the ski and lead to an undesired movement, forwards or backwards. To avoid this risk, it is then necessary to increase the stiffness of these tabs, which makes it difficult to perform the longitudinal adjustment operation without tools.

Document WO-A-2015/140258 proposes a mechanism for locking a deformable tongue provided with a notch. Locking is obtained by clipping or interference with a sliding plate. With this construction, there is a limited risk of acting on the deformable tongue. In these examples, the lock is exposed to external elements such as packed snow or ice which can accumulate in this area and disturb the locking mechanism and / or the actuation of the deformable tongue. In addition, the user may have doubts about the actuation of the lock after adjusting the longitudinal position.

The object of the invention is to propose a device for retaining a boot on an improved gliding board.

One aim is in particular to propose a mechanism for adjusting the longitudinal position of a retaining device on a reliable gliding board.

Another object is to provide a mechanism for adjusting the longitudinal position of a retaining device on a sliding board that is easy to use, in particular without tools.

Another object is to provide a mechanism for adjusting the longitudinal position of a retainer on a gliding board for which the user is sure to have a locked longitudinal position in use.

The invention proposes a device for retaining a boot on a sliding board, the retaining device comprising:

a mechanism for holding in position a hooking element belonging to the shoe, the holding mechanism comprising a movable jaw between a latching position for which the movable jaw is able to cooperate with the hooking element so to allow the attachment element to be secured to the retainer while allowing the boot to rotate about an axis transverse to the retainer, and a release position for which the movable jaw is in a configuration allowing the separation of the attachment element with the retaining device, and an actuating member controlling a movement of the movable jaw to tilt it from a latching position to a release position, a stop element longitudinal movable between an active position for which the longitudinal stop element is able to cooperate with complementary indexations secured to the gliding board for immobilizing the retaining device along the gliding board in one of several predetermined positions, and an inactive position for which the longitudinal stop element does not cooperate with the complementary indexings , a movable locking means between a locking position for which the locking means is able to cooperate with the stop element so as to maintain it in its active configuration and an unlocking position for which the movable locking means is in a configuration allowing tilting of the stop element from its active position to its inactive position.

The article is characterized by the fact that the locking means is kinematically linked to the movable jaw so that, when the locking means is in its locked position, the movable jaw is systematically in its engaged position.

Thanks to the invention, when the user actuates the shoe retention mechanism, the locking means systematically locks the longitudinal stop element. The locking means is implemented. It is then no longer possible to deactivate the longitudinal stop element, that is to say to move it relative to its active configuration, so that the longitudinal immobilization of the retaining device relative to the Sliding gear is long-lasting and secure. With this security, the user is assured that the adjustment of the longitudinal position of the shoe retainer will remain unchanged as long as his shoe is engaged with the binding. Furthermore, this construction makes it possible to design a longitudinal immobilization mechanism requiring little manipulation effort and therefore actuable without tools.

According to advantageous but not compulsory aspects of the invention, such a restraint device can incorporate one or more of the following characteristics, taken in any technically admissible combination:

- the locking means is a part of the actuating member,

- the locking means completely covers the longitudinal stop element when the locking means is in its locking position,

the locking means comprises an interference element dimensioned and arranged so that it is capable of interacting with the stop element to cause it to switch from its inactive position to its active position when the locking means switches from its unlocking position towards its locking position,

- the longitudinal stop element is movable in a direction transverse to the retaining device,

the longitudinal stop element comprises a positioning element able to cooperate with a complementary positioning element of the retaining device so as to maintain the longitudinal stop element in a stable position among the active or inactive positions,

the mechanism for holding the fastening element in position comprises a fixed jaw arranged so that the fastening element is positioned between the movable jaw and the fixed jaw when the shoe is engaged with the retaining device,

the retaining device comprises at least one guide edge capable of cooperating with a groove made on the sole of the shoe so as to limit the transverse movement of the sole when the sole approaches the gliding board,

The invention also relates to a gliding apparatus comprising a gliding board and a retaining device.

According to one embodiment, the gliding apparatus comprises an interface disposed between the gliding board and the retaining device, the interface carrying the additional indexings.

Other characteristics and advantages of the invention will be better understood with the aid of the description which will follow, with reference to the appended drawings illustrating, according to non-limiting embodiments, how the invention can be implemented, and in which :

In the following description, use will be made of terms such as "horizontal", "vertical", "transverse", "upper", "lower", "lateral", "up", "down", "right" , "Left", "front", "rear", "front", "behind". These terms must be interpreted relatively in relation to the normal position that the gliding device occupies when the user uses it on a substantially flat track.

We will also use a coordinate system whose front / rear direction corresponds to the X axis, the transverse or right / left direction corresponds to the Y axis and the vertical or top / bottom direction corresponds to the Z axis.

The invention relates to a sliding assembly 4 comprising a sliding board 3 extending along a longitudinal axis X3, an interface 2 fixed on the upper face 32 of the ski 3 opposite its sliding surface 31 and a retaining device 1 d 'a shoe 5, or binding, mounted on the interface with the possibility of sliding relative to the ski 3, along its longitudinal axis X.

The interface 2 is immobilized on the ski 3 by any appropriate means. This can be by gluing or by screws. The interface 2 has an upper face 20 and includes a central part 21 and two lateral wings 22 which extend on either side of the central part

21. In the rear part of the interface, each wing comprises a lug 221 projecting from the upper face 20. The lug 221 is formed on a deformable beam 222 dimensioned so that the lug can retract below the level of the upper face 20 when a vertical force Z is exerted on the lug. The outer edge of each lateral wing 22 forms a lateral rail extending in a direction parallel to the longitudinal axis X2 of the interface. The interface 2 is fixed to the ski so that the longitudinal axis X3 of the ski and the longitudinal axis X2 of the interface are parallel. In its central part 21, the interface 2 includes guide grooves 211 and a housing 212 intended to receive an insert 23, removably mounted on the interface. The insert 23 includes longitudinal guide grooves 231 as well as a series of notches 232 delimiting an edge of a central longitudinal groove 233. As we will see below, the series of notches 232 form additional indexings intended to cooperate with notches 1631 of a longitudinal stop element 16 so as to be able to immobilize the retaining device along the gliding board, in one of several predetermined positions. When the insert is assembled on the central part of the base, each notch 232 is oriented in a direction Y transverse to the base and opens into the central groove 233 and all the notches are aligned in a longitudinal direction X parallel to l longitudinal axis X2 of the interface. In use, the notches 232 are highly stressed because they are the ones which hold the retaining device in position, in the longitudinal direction X parallel to the longitudinal axis X2 of the interface. In addition, the dimensioning of these notches must be able to be accommodated in a small footprint, preferably in the thickness of the interface. These design constraints require the use of a suitable material to withstand the stresses. The proposed construction of adding a removable insert has several advantages. This allows, on the one hand, to change the part if the notching is damaged and, on the other hand, the use of more rigid material locally, where necessary, without penalizing the weight of the interface and therefore of the ski. For example, the insert can be metallic while the rest of the interface is plastic. The insert can be removably mounted on the interface by any suitable means. It can be by clipping or using a screw. This solution can be transposed to any system for adjusting the longitudinal position of a retaining device with respect to a ski using indexing means and is therefore not limited to the embodiment illustrated here. As a variant, the series of notches 232 is produced directly in the central part 21 and not on an attached insert.

The retaining device 1 comprises a base 11, a mechanism 17 for holding in position a fastening element 51 belonging to the shoe 5, a longitudinal stop element 16, a locking means 18 for the element longitudinal stop and a return means 19 making it possible to bring the heel of the boot towards the ski.

The base 11 is designed to be assembled with the interface 2. It extends along a longitudinal axis X1 substantially parallel to the longitudinal axis X2 of the interface when the base is mounted on the interface. The base includes a lower face 111 intended to come against the upper face 20 of the interface 2. The lower face 111 is delimited laterally by two flanges each forming an internal lateral groove 112 oriented in a longitudinal direction parallel to the longitudinal axis X1 of the base. Each internal lateral groove 112 is intended to cooperate respectively with a rail formed by one of the lateral wings 22 so as to guide in translation the base relative to the interface, in a longitudinal direction X. This cooperation also allows the maintenance of the lower face of the base against the upper face of the interface by preventing their spacing in a direction Z, normal to the upper face of the interface. This cooperation thus defines a slide-type connection between the base and the interface ensuring the sliding of the retaining device relative to the ski. To improve guidance in translation, the base also includes guide ribs 113 projecting from the lower face 111. Each guide rib is designed to cooperate with a complementary guide groove 211 formed on the upper face 20 of the interface 2. In its rear part, the lower face 111 comprises, on each side, a row of orifices 114 aligned in a direction X parallel to the longitudinal axis X1 of the base. Each orifice 114 is designed to receive a lug 221 of the interface 2 for a particular position of the base. Thus, when a lug 221 cooperates with an orifice 114 in a row, the base 111 is positioned at a determined indexed position. This cooperation provides indexing of the position of the base relative to the interface. However, the dimensioning of the pins and orifices is not sufficient to allow the longitudinal position of the base relative to the interface to be maintained. We will see later that this function is provided by another device.

In its upper rear part, the base 11 comprises at least one guide edge 115 capable of cooperating with at least one groove 53 formed on the sole 52 of the shoe 5 so as to limit the transverse movement of the shoe when the sole is closer to the gliding board 3.

Conventionally, the base 11 carries, in its upper part, the mechanism 17 for holding in position a fastening element 51 belonging to the shoe 5. In the illustrated embodiment, the fastening element 51 is a transverse shaft integrated in a recess in the front of the sole 52 of the shoe 5. In practice, the shoe 5 can comply with the technical teaching of applications EP-A-0 913 102 and / or EP-A -0 913 103 to which we can refer for more details. To secure the shoe with the retaining device, the holding mechanism 17 comprises a fixed jaw 12, a movable jaw 13, an actuating member 14 and rods 15. The operation will not be described in detail since it is similar to that of the attachment described in document FR-A-2638974.

The movable jaw 13 can move between a latching position, represented in FIG. 3, for which the movable jaw is able to cooperate with the hooking element 51 so as to allow the fastening of the hooking element with the retaining device while allowing the rotation of the boot about a transverse axis Y1 to the retaining device, and a release position for which the movable jaw is in a configuration, shown in Figures 1, 2 and 6, allowing the separation of the attachment element with the retaining device.

In this example, when the movable jaw 13 moves from its release position to its engaged position, the movable jaw 13 approaches the fixed jaw 12 so as to form substantially, with the fixed jaw, a cylinder at the interior capable of receiving the hooking element 51 so that it can freely pivot around the axis Y1 of the cylinder formed. Thus, the fixed jaw 12 is arranged so that the hooking element 51 is positioned between the movable jaw 13 and the fixed jaw 12 when the shoe 5 is engaged with the retaining device 1. Conversely, when the movable jaw 13 moves from its latching position to its release position, the movable jaw 13 moves away from the fixed jaw 12 so as to generate an opening between the two jaws through which the element can pass attachment 51. In this example, the movable jaw 13 is positioned in front of the fixed jaw 12 on the base 11.

To tilt the movable jaw from its latching position to its release position, or vice versa, the holding mechanism 17 comprises a control device actuated by an actuating member 14 which can be manipulated by the user. In the example illustrated, the control device is similar to that described in document FR-A-2638974. It comprises an actuating member 14 in the form of a cover pivotally mounted on the body of the movable jaw 13 around a transverse axis Y14. Furthermore, each side edge of the cover 14 is connected to a front part of the base 11 by a link

15. A first end of the link is rotatably mounted on the front part of the base around a transverse axis Y15a. A second end of the link is rotatably mounted on a lateral edge of the actuating member around a transverse axis Y15b parallel to the pivot axis Y14 of the actuating member.

By lowering the actuating member 14, the user causes the movable jaw 13 to move towards its engagement position. Conversely, by lifting it, the actuator controls the movement of the movable jaw to tilt it from the latching position to the release position. In this example, when it is completely lowered, the actuating member 14 is designed to come into abutment against an upper front face 116 of the base 11. In this configuration, the movable jaw is in its engagement position .

In this example, the control device is designed to lock the movable jaw in the engaged position. Thus, when the actuator is fully raised, the movable jaw is in its release position. By lowering the actuator by a determined angle, the movable jaw is brought to its engagement position. Then, by continuing the rotation of the actuating member until it comes to bear against an upper front face 116 of the base 11, the movable jaw is locked in its engaged position and can no longer move longitudinally, in direction X, without any action on the actuating member.

The actuating member 14 defines a cover incorporating a lower recess 141 provided to form, with the upper front face 116 of the base 11 and a part of the body of the movable jaw 13, a volume that is substantially closed when the actuation 14 rests on the upper front face 116 of the base 11. Thus, in this configuration, the actuation member 14 makes it possible to protect the elements housed in this cavity from external weather conditions such as snow or ice. The rods 15 are arranged to be housed in this cavity when the actuating member 14 is lowered, that is to say, when the retaining device is engaged.

According to one embodiment, the return means 19 making it possible to bring the heel of the boot towards the ski is an elastic pad carried by the body of the movable jaw 13. The elastic pad 19 is designed to bear against a front face of the sole when the user lifts his heel. This type of return means is illustrated in document FR-A-2638974.

According to the invention, the retaining device comprises a longitudinal stop element 16 movable between an active position, shown in FIGS. 2, 6 and 8, for which the longitudinal stop element is able to cooperate with additional indexings 232 integral with the gliding board in order to immobilize the retaining device along the gliding board in one of several predetermined positions, and an inactive position, shown in FIGS. 1 and 7, for which the stop element longitudinal does not cooperate with additional indexing. In this example, the longitudinal stop element 16 is a pusher inserted in a through housing 117 of the front part of the base 11 so that an upper part of the stop element protrudes from the upper face. 116 of the base 11 and that a lower part of the stop element protrudes from the lower face 111 of the base 11. Furthermore, the housing is also designed to allow sliding of the pusher 16 in a direction Y16 transverse to the base between its active and inactive positions. Thus, the longitudinal stop element is movable in a direction transverse to the retaining device.

In its upper part, the stop element 16 comprises, on one side, a first transverse extension 161 delimited laterally by a first actuating surface 1611 inclined with respect to a vertical plane, advantageously, by an angle greater than 25 ° and less than 50 °. On the opposite side, the stop element comprises a second transverse extension 162 delimited laterally by a second actuating surface 1621 inclined with respect to a vertical plane, advantageously, by an angle greater than 25 ° and less than 50 °. These actuating surfaces are arranged so that when the user presses on the first actuating surface 1611, he drives the translation of the stop element 16 in a transverse direction Y16 to cause it to tilt from its inactive position towards its active position. Conversely, when the user presses on the second actuating surface 1621, he drives the translation of the stop element 16 in a transverse direction Y16, in the other direction, to cause it to tilt from its position active to its inactive position. Each transverse extension 161, 162 has a lower surface 1612, 1622 intended to be positioned against the upper face 116 of the interface 11.

Each transverse extension 161, 162 also comprises a positioning element 1613, 1623 formed respectively on the lower surface 1612, 1622 of a transverse extension 161, 162. For certain transverse positions of the stop element 16, a positioning element 1613, 1623 is able to cooperate with a complementary positioning element 118 formed on the upper surface 116 of the interface 11 so as to maintain the stop element 16 in this stable position. Thus, when the stop element 16 in its inactive position, the positioning element 1613 of the first transverse extension 161 cooperates with a first complementary positioning element 118 of the base 11. Furthermore, when the element d stop 16 in its active position, the positioning element 1623 of the second transverse extension 162 cooperates with a second complementary positioning element 118 of the base 11. The longitudinal stop element comprises a positioning element 1613, 1623 able to cooperate with a complementary positioning element 118 of the retaining device so as to maintain the longitudinal stop element 16 in a stable position among the active or inactive positions. In this example, a positioning element 1613, 1623 is a boss projecting from the lower surface 1612, 1622 of a transverse extension 161, 162. In this case, a complementary positioning element 118 is a recess formed on the upper surface 116 of interface 11.

In its upper part, the stop element 16 comprises a lower extension 163 projecting from the lower face 111 of the base 11 when the stop element is assembled on the base. This lower extension 163 comprises two notches 1631 oriented in a direction Y, transverse to the base when the stop element is assembled on the base. The notches 1631 are dimensioned and arranged so that they can cooperate with the complementary indexations 232 of the base when the stop element is in its active position and so that they no longer cooperate with the complementary indexations 232 of the base when the stop element is in its inactive position. In the latter case, the lower extension 163 is positioned in the central longitudinal groove 233. Thus, when it is in its inactive position, the stop element 16 can move along the interface 11, in the central longitudinal groove 233. On the other hand, when it is in its active position, the stop element 16 is integral with the interface 11 in the longitudinal direction X because the notches 1631 are engaged with the complementary indexings 232 of the base. The stop element 16 therefore allows the immobilization of the retaining device along the gliding board in one of several predetermined positions. The predetermined positions are defined by the position of the complementary notches / indexing 232. In order to be able to switch the stop element 16 from its inactive position to its active position, the retaining device 1 must be positioned relative to the interface 2 in one of several predetermined longitudinal positions. For each of these predetermined longitudinal positions, a lug 221 of the interface 2 will cooperate with an orifice 114 of the base 11. These longitudinal positions are thus indexed positions, relatively stable, each allowing the tilting of the element d stop 16 from its inactive position to its active position. In addition, to facilitate adjustment of the longitudinal position of the retaining device, the base can include one or more marks 119 intended to cooperate respectively with one or more graduations 201 formed on the upper surface 20 of the interface, as is see in Figures 1 to 5. Thus, the user has a visual reference to determine the exact longitudinal position of the base relative to the interface. Other embodiments of this visual indicator can be envisaged.

In this example, the stop element 16 is dimensioned and positioned so that it is housed in the cavity delimited by the actuating member 14 and the upper face 116 of the base, when the element stop is in active position. In this configuration, the actuator 14 completely covers the stop element 16 which makes it possible to protect it from the weather when the user is skiing.

According to the invention, the retaining device also comprises a locking means 18 movable between a locking position, shown in FIG. 8, for which the locking means is able to cooperate with the stop element 16 so as to keep it in its active configuration and an unlocking position, shown in Figure 7, for which the movable locking means is in a configuration allowing the switching of the stop element from its active position to its inactive position. The locking means 18 comprises an interference element 142 which is capable of interfering with a part of the stop element 16 when it moves from its active position to its inactive position. The stroke of the stop element to switch from an active position to an inactive position is then limited so that the stop element always allows the connection between the retaining device and the interface in its longitudinal direction X When the locking means switches to the unlocking position, the interference element 142 retracts, thereby releasing the travel of the stop element which can therefore switch to the inactive position.

According to the illustrated embodiment, the locking means 18 is a part 142 of the actuating member 14. The locking position corresponds to the position of the actuating member when it is lowered while the unlocking position corresponds to the position of the actuator when it is raised. The interference element 142 is produced by an internal rib projecting from the surface defining the lower recess 141 of the actuating member 14. When the actuating means is in its locked position and the element stop is in its active position, as shown in FIG. 8, the interference element 142 is positioned facing the first actuation surface 1611 of the stop element, thus preventing movement of the stop member to its inactive position.

According to one embodiment, the locking means 18 comprises an interference element 142 dimensioned and arranged so that it is able to interact with the stop element to make it switch from its inactive position to its active position when the locking means switches from its unlocking position to its locking position. The interaction between the interference element 142 and the stop element 16 can be carried out by direct contact. In this example, the internal rib 142 has a surface complementary to the first actuating surface 1611 capable of coming into contact with a portion of the first actuating surface 1611, when the actuating member 14 is lowered. , when the stop element 16 is in the inactive position. Thus, when the user lowers the actuating member, the internal rib comes into contact with the first actuating surface of the stop element. Then, by continuing the rotation of the actuating member to bring the movable jaw into its latching position, due to the complementarity of the inclined surfaces, the interference element 142 pushes the stop element for the switch from its inactive position to its active position. Thanks to this construction, the tilting of the movable jaw towards its latching position simultaneously causes the locking of the stop element and therefore the longitudinal immobilization of the retaining device relative to the ski. Automatic locking is therefore obtained by actuating the holding mechanism 17 to secure the shoe to the retaining device. Thus, with a single manipulation, the user can both secure his shoe with the binding and lock the adjustment of the longitudinal position of the retaining device.

The invention relates to the fact that the locking means 18 is kinematically linked to the movable jaw 13 so that, when the locking means is in its locked position, the movable jaw is systematically in its engaged position. Within the meaning of the invention, a part is kinematically linked to the movable jaw 13 when there is a relationship between the position of the part and the position of the movable jaw. Thus, for a determined position of the part, this connection induces a determined position of the jaw. The part can be directly fixed on the movable jaw or its body. Consequently, a translational movement of the movable jaw causes the same translation of the associated part. Alternatively, the part can be mounted movable relative to the movable jaw or its body. In this case, a translational movement of the movable jaw causes a movement of the associated part. For example, it may be a rotation of the part relative to the body of the movable jaw, by means of the links, as in the illustrated embodiment.

In this example, the locking means 18 is a part 142 of the actuating member 14 of the holding mechanism 17 and therefore, by construction, directly linked to the kinematics of the movable jaw. Alternatively, the locking means may be another part of the holding mechanism 17. It may be, for example, an element carried by the body of the movable jaw. Thanks to the invention, when the boot is engaged with the retaining device, the user is assured that the retaining device is locked longitudinally on the ski.

According to one embodiment, the retaining device is directly fixed to the gliding board, without a separate interface part. In this case, the upper face of the ski incorporates the elements allowing the assembly of the retaining device on the ski.

It is possible to envisage other embodiments of the mechanism for holding in position a fastening element belonging to the shoe. For example, the movable jaw can be positioned back on the retainer relative to the fixed jaw. The holding mechanism may not have a fixed jaw. For example, the movable jaw can be produced by two transversely movable points, arranged symmetrically with respect to the longitudinal median plane of the ski, each point being able to cooperate with a housing formed on a lateral edge of the front of the sole of the shoe. . Such a construction is illustrated, for example, in document EP-A-0199098. Likewise, other actuator solutions can be envisaged. This 5 can be a rotary button or a push button.

Furthermore, it is also possible to envisage other constructions of a longitudinal stop element. For example, the stop element can cooperate with additional indexing in a direction Z, normal to the upper surface of the interface. The stopper can be coupled with elastic means so as to keep it in a stable position, for example, its active position.

The invention is not limited to these embodiments. It is possible to combine these embodiments.

The invention is not limited to the embodiments previously described but extends to all the embodiments covered by the appended claims.
