Definitions

  • the blocking element may comprise a lug
  • the blade may comprise a first opening comprising a shape complementary to a shape of the lug, the lug cooperating with the first opening when the blocking element is in the blocking position.
  • the blocking element may comprise a first portion, in particular of cylindrical shape, capable of cooperating with said first opening to block the articulation in rotation between the collar and the bottom of the shell when the blocking element is in the blocking position, and a second portion, in particular of prismatic shape, the second portion having at least one flat face forming the first guide surface.
  • the locking device may comprise a housing fixed to the collar, the housing comprising means for guiding the blocking element in translation parallel to a first axis between its locking position and its unlocking position.
  • the locking device may comprise a shaft integral with the blocking element, a housing comprising at least a first guide light, a carriage movable relative to the housing, the carriage comprising at least a second guide light, the cooperating shaft with the at least one first guide light and with the at least one second guide light so that a movement of the carriage relative to the housing causes a movement of the blocking element.
  • the blocking element 22 also comprises a first guide surface 53 and the blade 12 comprises a second guide surface 54, the first guide surface 53 cooperating with the second guide surface 54 to guide the movement of the blade 12 relative to the blocking element 22 when the blocking element is in the unlocked position and the collar pivots relative to the bottom of the shell.
  • the guiding device comprises a means of permanent guidance between the blocking element 22 and the blade 12. This makes it possible to guarantee good positioning of the blocking element 22 relative to the blade 12 in all circumstances.
  • the blocking element 22 therefore combines a function of blocking the blade 12 and a function of guiding the blade. This makes the locking device easier to handle and more robust.
  • the housing 21 comprises a guide means 25 capable of guiding the blocking element 22 in translation parallel to the first axis X1.
  • This guide means 25 is in particular formed by a jacket whose shape corresponds to the profiled shape of the blocking element 22. This guide means makes it possible to properly control the translation movement of the blocking element 22, and thus to further limit any risk of jamming between the blocking element and the blade 12.
  • the blocking element 22 can be a one-piece element, that is to say an element formed from a single piece.
  • the blocking element could for example come from a block of machined metal.
  • the blocking element could comprise several parts fixed together, the different portions 55, 56 and 57 of the blocking element could for example be screwed or welded together.
  • the blocking element 22 is made of metal, so as to resist the significant efforts that a user may exert when practice of alpine skiing.
  • it could also be made of injected plastic, in particular plastic loaded with glass or carbon fibers in order to increase its resistance.
  • the blade 12 comprises a groove 58.
  • the groove 58 is an opening passing through the thickness of the blade and extending parallel to the axis in which the blade extends, that is to say parallel to the second Z2 axis.
  • the groove is delimited by two lateral edges extending parallel to the second axis Z2.
  • the length of the groove 58 along the second axis Z2 is adapted according to the amplitude of flexion of the collar relative to the bottom of the shell.
  • Said second guide surface 54 is formed by at least one of the two edges of the groove 58, in particular by all of the two edges, the two edges being intended to bear on the flat faces of the second portion 56 of the element blocking 22.
  • the blade 12 could be without the groove 58 and the guidance between the blocking element 12 and the blade 22 could be produced differently.
  • the blade 12 could comprise a profiled U shape.
  • the wings of the U would be spaced at a distance slightly greater than the diameter of the blocking element, so that the blocking element slides between these two wings when the collar pivots relative to the bottom of the shell.
  • the blocking element 22 could comprise substantially the shape of an M. It would comprise a central part intended to cooperate with the opening 14 and lateral wings intended to bear on the external edges of the blade 12.
  • a first end of the cable 11 is inserted through a hole provided in the base 29 of the carriage 26. This first end is provided with a means of retainer 35 intended to rest on the edge of said hole. Pulling the cable 11 thus causes sliding, or in other words a translation, of the carriage 26 inside the housing 21 parallel to the second axis Z2.
  • the two lateral flanks 28 of the housing 21 each comprise a first guide light 31 oriented parallel to the first axis X1.
  • the two lateral sides 30 of the carriage 26 each comprise a second guide light 32 oriented parallel to a third axis A3.
  • the third axis A3 forms with the first axis X1 an angle B different from 90°.
  • the second guide lights 32 are positioned opposite a rear end of the first guide lights 31.
  • the shaft 33 which extends through the first guide lights 31 and the second guide lights 32 is therefore in a more rearward position.
  • the blocking element 22, secured to the shaft 33, is then in the unlocked position.
  • the blocking element 22 is then in the blocking position.
  • the blocking element 22 is thus able to engage with the opening 14 of the blade 12.
  • angle B formed between the first axis A1 and the third axis A3 is to 90°, the greater the travel of the carriage 26 must be to move the blocking element 22 between its blocking position and its unlocking position, which contributes to the increase in the volume of the mechanism 20.
  • This angle B is necessarily different from 90° because otherwise the movement of the carriage would not generate any movement of shaft 33.
  • the third axis A3 can form with the first axis X1 an angle B of between 10° and 85° inclusive, preferably between 40° and 75° inclusive, more preferably between 50° and 70°.
  • the mechanism 20 further comprises a return means 34 configured to move the carriage 26 in the direction opposite to the direction of movement controlled by the actuation of the cable 11.
  • the return means 34 can in particular be obtained by a compression spring comprising a first end resting against the base 29 of the carriage and a second end resting against a wall of the second part 21B of the housing.
  • a compression spring comprising a first end resting against the base 29 of the carriage and a second end resting against a wall of the second part 21B of the housing.
  • the guide lights 32 of the carriage are oriented downwards and towards the rear, so that the low position of the carriage corresponds to the blocking position of the blocking element, and the high position of the carriage corresponds to the position of unlocking the blocking element. Pulling on the carriage 26 by the cable 11 therefore causes the blocking element to move towards its unlocking position. Conversely, in the absence of tension on the cable 11, the blocking element is in its blocking position.
  • the second lever 42 is movable between a first position and a second position.
  • the second lever 42 When the second lever 42 is in its first position, it does not exert any traction force on the cable 11.
  • the blocking element 22 is then in the blocking position thanks to the effect of the return means 34.
  • the second lever 42 Conversely, when the second lever 42 is in its second position, the cable 11 is under tension.
  • the carriage 26 is then moved against the return means 34 and the blocking element 22 is in the unlocked position.
  • the collar joint on the bottom of the shell is released and the collar can pivot backwards or forwards.
  • the rear spoiler 46 is mobile in rotation relative to the bottom of the shell 2 around a transverse axis corresponding to the fourth axis Y4.
  • a support 48 for example in the form of a metal part, is on the one hand rigidly fixed to the rear spoiler 46, and on the other hand is fixed to the axis 43 according to a rotational connection of axis Y4.
