Definitions

  • the subject of the present invention is a ski boot consisting of at least one lower part intended to surround the foot and the heel and a rod articulated on this lower part and comprising, at the rear, connecting means between the rod and the lower part, these connecting means comprising means for fixing or releasing the rod in rotation relative to the lower part, means for adjusting the inclination of the rod relative to the lower part by a screw / nut system, at least one elastic element, and means for adjusting the elasticity of this elastic element.
  • Such a shoe is described in document DE-A-2 057 094.
  • the lower part of the connecting bar is screwed into a nut rotatably mounted in a support integral with the shell and in which it is retained axially.
  • This nut is intended to be driven in rotation for adjusting the inclination of the upper of the shoe.
  • the upper part of the connecting bar has a collar mounted between two springs working in compression in a tube integral with the upper of the shoe. The device does not release the upper of the shoe to allow it to oscillate in the walking and resting position.
  • the rod and the shell are connected by a connecting bar, the lower part of which has perforations in which engages a lock mounted on the shell and making it possible to obtain several different inclinations of the shoe upper.
  • the lock can further be kept in the unlocked position, so that the rod can oscillate.
  • a ski boot is also known, the rod of which, articulated on the shell, is connected to the shell, at the rear, by a screw with two threads of opposite pitch provided a drive wheel, part of which is screwed into a stud secured to the shell and the other part is screwed into a bar, the upper end of which is provided with a nut allowing the pre-compression of the two springs to be adjusted coaxial housed in a cage mounted sliding on the upper of the shoe, but capable of being locked on this upper by a cleat articulated on the upper.
  • the link bar is therefore here made up of two parts and requires three left and right threads.
  • Document EP-A-0206 394 describes a device with adjustable elasticity consisting of a block of non-compressible elastic material, the expansion of which, during axial pressure, is controlled by a rigid sleeve displaceable around the elastic block.
  • This device is mounted between a rod, articulated on the shell, and the shell, at the front or at the rear of the shoe.
  • This elastic device has the advantage, in addition to great simplicity, of having no prestressing at rest.
  • the present invention aims to achieve a compact device, simpler and without spring, filling the three functions mentioned above, namely locking and unlocking of the upper of the shoe, continuous adjustment of the inclination of this upper and adjustment of the flexural strength of this upper.
  • the shoe according to the invention is defined in claim 1.
  • the connecting means according to the invention make it possible to achieve the three desired functions with very simple means.
  • FIG. 1 represents a side view of the rear part of a ski boot in which a part of the upper has been cut to reveal the connection means between the upper and the lower part of the boot.
  • Figure 2 is a back view of the shoe.
  • Figure 3 is an enlargement of Figure 1.
  • the shoe partially shown in Figures 1 to 3 is a shell shoe in synthetic material of known design. It comprises a lower or lower part of the shell 1 surrounding the foot and the heel and a rod or cuff 2 articulated at 3 on the lower part 1.
  • the rod 2 is also connectable to the lower part 1 by connecting means essentially comprising a bar 4 extending in a vertical plane parallel to the back 5 of the rod 2 and a cylindrical lock 6 cooperating with a hole 7 of a metal plate 8 fixed on the lower part 1 of the shoe.
  • the bar 4 has a threaded lower end 4a screwed into a metal block 9 in which the latch 6 is mounted.
  • This latch 6 has an extension 6a of reduced diameter passing through the block 9 and projecting outside the rod 1 of the shoe through a slot 10. At the end of this extension 6a is articulated an eccentric lever 11 around an axis 12.
  • the lock 6 is pushed towards the hole 7 by a spring 13 housed in the block 9.
  • a wheel 14 integral in rotation with the bar, but which can slide thereon.
  • the wheel 14 is mounted between two bearing surfaces 15 and 16 of the back 5 of the upper 1 of the shoe so that it protrudes from this back of the upper just enough for its actuation by means of the thumb.
  • the bar 4 also crosses a cylindrical sleeve 17 of rubber as well as a cylinder 18 of rigid, metallic or synthetic material, placed above the elastic sleeve 17 and retained by a washer 19 itself retained by a key 20 near the rounded end of the bar 4; this rounded end bears against a surface 21 of the back of the rod 1.
  • a sliding sleeve 22 rigid in metal or in synthetic material which can also slide, with a weak play, around sleeve elastic 17.
  • This sliding sleeve 22 is provided with a radial arm 23 passing through the back 5 of the rod through a slot 24 parallel to the bar 4.
  • the arm 23 is provided with a drive button 25 by means of which the user can slide the sliding sleeve 22.
  • the latch 6 In the position of the handle 11 shown in solid lines, the latch 6 is engaged in the hole 7 and the upper 1 of the shoe cannot therefore pivot around its articulation 3.
  • C is the descent position.
  • the lock 6 By tilting the lever 11 downwards in the position 11 ′ shown in phantom, the lock 6 is released from the hole 7 as shown in 6 ′ and the rod 1 can then pivot freely around its articulation 3. This is the walking or resting position.
  • the knob 14 which has the effect of screwing or unscrewing the bar 4 of the block 9 and consequently of lengthening or shorten the length L between the axis of the latch 6 and the upper end of the bar 4, that is to say the length of this bar 4.
  • the upper end of the bar 4 determining the point of support of the upper 1, if this fulcrum is higher, for example, the upper 1 will have to tilt towards the front of the shoe.
  • Sufficient play is provided between the latch 6 and the hole 7 to allow a slight tilting of the bar 4 relative to the position shown in Figure 1, either forward or backward.
  • connection between the upper and the lower part of the shoe is however rigid as regards the tilting of the upper backwards.
  • the lock could be made differently.
