Definitions

  • the invention relates to a sports shoe which comprises a lower part, called bottom shell and a high part called necklace.
  • the invention relates in particular to devices for blocking and then unblocking the movement of the collar relative to the bottom of the shell.
  • the locking device is located in the dorsal zone of the shoe and interacts between the collar portion and the bottom shell portion of the boot via a pivoting piece mounted on a pivot.
  • This tilting piece made integral with the collar, in particular with the aid of its pivot, is provided to be able to occupy alternately two determined angular positions, one to oppose the pivoting of the collar relative to the shell bottom in the antero direction. -post and the other, to let the collar free to rotate in this direction.
  • the tilting piece has a bearing zone at the end of a free arm which extends downwardly below its pivot and in correspondence of a stop means which is provided with the bottom of the shell .
  • the locking device described in this document is particularly bulky because the collar comprises a cover which covers the device.
  • the pivot of the tilting piece is in a central position midway between the bearing zone and the upper part which is connected to the means for actuation.
  • the present invention aims to overcome the disadvantages of the prior art.
  • the present invention aims to provide a locking device which ensures a good distribution of forces without risk of damaging the parts constituting it.
  • the present invention also aims to provide a locking device that is well integrated in the shoe.
  • the present invention also aims to provide a locking device which is not too large.
  • the present invention also aims to provide a device that is cheap.
  • the present invention also aims to provide a locking device that requires few parts for its implementation.
  • the object of the invention is achieved by providing a shoe oriented along a longitudinal axis comprising a shell bottom and a collar, hinge means being provided between the collar and the shell bottom so that the collar can pivot relative to the shell bottom along an axis of articulation, which is substantially perpendicular to said longitudinal axis and further comprising a device for blocking the rotation towards the rear of the collar relative to the shell bottom, said devices blocking rearward rotation comprising: a rocker rotatably mounted relative to one of the two following elements, the collar or the shell base around a first pivot, said pivot being oriented along a first axis A1 and said rocker having an elongated shape between an upper end E1 and a lower end E2 and said first pivot being placed near one of the two ends E1 or E2; a bearing block, placed close to the other of said ends E2 or E1, comprising a first bearing surface, which is capable of coming into contact with the other of said following elements, the shell bottom or the collar; and a lever rotatably mounted relative to
  • said rocker is rotatably mounted on said collar, said first pivot is placed close to the upper end E1 and in that said bearing block is placed near the lower end E2.
  • Said locking device is likely to be in a blocking state in which it hinders the rearward rotation of the rotation movement of the collar relative to the shell bottom or in a release state in which this rotation is not hampered.
  • said first bearing surface of said bearing block corresponds to said other of said ends E2 or E1 and the ratio between the distance d1 separating the first pivot from the first end E1 and the distance d4 separating the first pivot from the second end E2 is between 0.15 and 0.35, preferably between 0.2 and 0.3. In one embodiment of the invention, this ratio is substantially equal to 0.23 ⁇ 0.02.
  • the ratio between the distance d2 separating the first pivot from the second pivot, the distance d4 separating the first pivot from the lower end E2 is between 0.2 and 0.5, preferably between 0.3 and 0, 4. In one embodiment of the invention, this ratio is substantially equal to 0.36 ⁇ 0.02.
  • said rocker can pivot between a locking position in which during the rearward movement of rotation of the collar, said first bearing surface comes into contact with a sidewalk formed on the bottom of the shell, and an unlocking position. , in which, the rocker does not hinder the rotation of the collar rearward and in that the amplitude of the rotational movement of the rocker corresponds to an angle ⁇ whose value is between 3 ° ⁇ ⁇ 25 °, preferably between 5 ° ⁇ ⁇ 15 °.
  • said locking device further comprises return means which return said locking device to the blocking state, these biasing means may comprise a spring placed at the upper end E1.
  • said lever allows the transition from the blocking state to the unlocking state of the locking device, when the pallet of said lever is actuated in rotation by the user by an amplitude corresponding to an angle ⁇ whose value is between 90 ° and 160 °, preferably between 120 ° and 150 °.
  • the value of this angle is substantially equal to 135 ° ⁇ 2 °.
  • said cam surface comprises an initial portion located at a distance C1 of said second pivot, a final portion located at a distance C2 of said second pivot, in that when said devices are in the unlocked state the final portion bears on the rolling surface and in that C1 ⁇ C2 ⁇ 10 mm.
  • said bearing block comprises a second bearing surface which when the locking device is in the blocking state, is likely to be in contact with a stop on said collar.
  • the figure 1 shows a perspective view of a sports shoe. This is a shoe designed for skiing.
  • the boot 1, oriented along the longitudinal axis L, comprises a bottom shell 2 and a collar 3.
  • the shell bottom 2 comprises a sole 15 and vertical flanks 16 from the sole 15.
  • the vertical flanks 16 define with the sole 15 a cavity provided to receive the foot of a user.
  • the upper part of the shell bottom is constituted by an opening for the introduction of the foot.
  • a collar 3 extends the shell bottom 2 towards the leg of the user.
  • the collar 3 is fixed to the shell bottom 2 by means of two hinge pins 17 placed facing each other, one on the medial side of the shoe, the other on the lateral side of it. This attachment of the collar 3 on the shell bottom 2 gives it the possibility of pivoting along the axis defined by the two axes of articulation, that is to say in the forward / backward direction.
  • the pivoting of the collar 3 relative to the bottom of the shell 2 has an amplitude of less than 30 ° and it makes walking easier. Indeed, when the foot of the user is caught in a rising shoe, which covers the ankle joint, the latter is hampered in its movements.
  • the articulation collar / bottom of shell gives back to the ankle a certain laxity forward / backward.
  • the shell bottom 2 and the collar 3 are generally made of synthetic materials, such as plastics. They are not necessarily made of a single piece but can be constituted by an assembly of different elements whose details will not be described here.
  • Some sports practices require immobilization of the ankle joint, or at least they require that this joint is limited in its amplitude. This is the case of skiing, and some mountaineering practices. This is why the shoe 1 is equipped with a locking device 20 whose function is to block the articulation of the collar 3 with respect to the shell bottom 2.
  • This locking device 20 is placed in the rear zone of the boot 1. It is fixed on the collar 3 and acts on the shell bottom 2.
  • the locking device can be in the blocking state and in the unlocking state.
  • the device In the unblocking state, the device does not ensure the limitation of the rearward rotation of the collar 3 relative to the shell bottom 2, and it does not prevent the rotation towards the front of the latter.
  • This is the "ON" position. In the “ON” position the user must not only be able to bend forward. But he must also be able to rotate the ankle joint backwards every time he puts his foot on the ground. He therefore needs the ankle joint to work forward without limit.
  • the rocker 4 is mounted on the collar 3 via a first pivot 6.
  • the first pivot 6 is made using a shaft which can be a stud or a metal rod.
  • the first pivot 6 is oriented along an axis A1, which is substantially transverse to the shoe.
  • the rocker is in the form of an elongated piece, which extends from a first upper end E1 to a lower end E2.
  • the rocker 4 further comprises a bearing block 10 located in its lower part. Between the first pivot 6 and the support block 10 is a second pivot 7.
  • the bearing block 10 comprises a first bearing surface 18 which is capable of coming into contact with the shell bottom 2 and a second surface. 19 which is likely to come into contact with a stop 24 formed on the collar 3.
  • the first pivot 6 is placed near the upper end E1.
  • the ratio between the distance d1 separating the first pivot 6 from the first end E1 and the distance d4 separating the first pivot 6 from the second end or the lower end E2 is between 0.15 and 0.35. This ratio is preferably between 0.2 and 0.26. In other words we can write the following mathematical equation: 0 , 2 ⁇ d ⁇ 4 ⁇ d ⁇ 1 ⁇ 0 , 26 ⁇ d ⁇ 4
  • the ratio between d1 and d4 is substantially equal to 0.23.
  • the smallness of the ratio between d1 and d4, between 0.1 and 0.3 preferably between 0.2 and 0.26, has the consequence that in its movement around the first pivot 6, the upper end E1 will have a much lower amplitude of movement than that of the lower end E2.
  • the passage of the locking device in the unlocking state will generate a movement towards the outside of the end E2 while the upper end E1 will be moved with a movement towards the inside.
  • the movement inward of the upper end E1 of course requires the development of a corresponding cavity in the collar 3 to allow the end E1 to enter the collar.
  • the smallness of the ratio d1 / d4 has the consequence that the cavity to be formed in the collar must be relatively small.
  • the bearing block 10 comprises a first bearing surface 18, which merges with the second end E2, and a second bearing surface 19 in the blocking state, the first bearing surface 18 is in position. contact with a sidewalk 11 formed in the shell bottom, while the second bearing surface 19 is in contact with a stop 24 formed in the lower part of the collar 3.
  • the bearing block 10 occupies a protruding position relative to the rest of the rocker 4. Thus it can easily come to interpose between the abutment 24 of the collar and the sidewalk 11 of the bottom of the hull.
  • the second pivot 7 also made by means of a metal rod or a rivet or by any other known means is oriented along an axis A2.
  • the lever 5 is in the form of a jumper extended by a pallet 13 for actuating the latter.
  • the two branches of the rider are bearings 25 which are placed on each side of the rocker 4.
  • the bearings are pierced with an opening provided for receiving the second pivot 7, and their outer surface is constituted by a cam surface 26 intended to come into contact with a rolling surface 23 formed on the collar 3.
  • the locking device also comprises return means 14 provided to bring the lower part of the rocker 4, that is to say the bearing block 10, against the boot.
  • these return means 14 are in the form of one or more springs working in compression which is placed at the end E1.
  • the cam surface 26 formed on each of the bearings 25 has a final portion 21, which is at a distance C1 from the second pivot 7, and a final portion 22, which is at a distance C2 from the second pivot 7. blocking is in the blocking state, it is the initial portion 21 of the cam surface 26 which is opposite the rolling surface 23, formed on the collar 3.
  • the rocker 4 is pivotally mounted relative to the collar 3 around the first pivot 6, while the lever is pivotally mounted relative to the rocker 4 around the second pivot 7. It will be seen later that the rotation of the lever 5 causes the pivoting of the rocker 4 by the effect of the cam surfaces disposed on the bearings.
  • the Figures 4 and 5 describe the previous shoe in the unlock state, that is, in the "ON" position.
  • the rocker 4 is pivoted around the first pivot 6 so that its lower end E2 is displaced towards the outside of the shoe 1.
  • the rotational movement of the rocker 4 must have an amplitude such that the tip of the rocker 28 is no longer facing sidewalk 11.
  • the amplitude of this movement corresponds to an angle ⁇ whose value is between 3 ° and 25 °, preferably between 5 ° and 15 °. In the example shown, ⁇ is between 8 ° and 10 °.
  • the abutment 24 of the collar and the sidewalk 11 of the shell bottom are free of relative movement relative to each other and they can move closer to each other. There is no more back support. Walking is then facilitated because of the lack of back support, the user can lay flat foot in front of him.
  • the rotational movement of the rocker 4 is generated by the action of the user on the lever 5.
  • the latter is represented at the figure 5 when the locking device is in the unlocking state.
  • the transition from the blocking state to the unlocking state occurs when the user moves the pallet 13 of the lever 5 upwards.
  • the rotational movement of the lever 5 around the second pivot 7 is a movement whose amplitude is materialized at the figure 4 a straight line connecting the second pivot 7 and the tip 27 of the lever in both positions.
  • the amplitude of this movement corresponds to an angle ⁇ , which is between 90 ° and 160 °, preferably 120 ° and 150 °. In the example shown, ⁇ is substantially equal to 135 °.
