Abstract

The boot is of the type with a shell 1 on which an upper 2 is articulated. This upper is equipped with a rocker 9, the lower end 9b of which interacts with a notch 13 of the shell in order to hold the upper 2 in the inclined position. The rocker 9 is equipped with a movable piece 16 making it possible to lock the rocker in a non-operating position for resting or walking.

Description

The present invention relates to a ski boot consisting of a

lower part surrounding the

  foot and heel and an articulated rod on this part

  lower tie and comprising, at the rear, means for locking the rod in the advanced position, means

  consist of a rocker pivoted around a horizontal axis

  zontal in a cutout of the back of the upper and the lower arm of which abuts, in the locked position, against a solitary stop of the lower part of the shoe, said rocker being held in this

  position by a spring, pressure on the upper arm

  laughter of the rocker to move the rocker away from

the stopper to release the rod.

  Such shoes are known from documents EP-A-0 086 908 and EP-A-0 286 586. When the rocker is in abutment on the lower part of the shoe, the upper of the shoe takes a minimum inclination necessary for practice. ski. If the skier wants to rest, that is to say straighten the leg, or walk, he just has to press on the rocker and straighten the leg, the lower end of the rocker can then pass over the stop. A simple bending of

  the leg returns the rod to the inclined locked position

  lée. If this automatic return to the locked position is particularly practical when the skier leaves a rest position to start or start skiing again, such automatic locking can be unpleasant if it occurs unexpectedly while walking, which can happen especially during a

walking on a slope, uphill.

  The object of the present invention is to obviate this inconvenience.

comes.

  To this end, the shoe according to the invention is charac-

  terrified by the fact that the upper arm of the rocker

  has a moving part on the scale and action-

  manually movable, can be placed in a posi-

  tion as it extends the upper end of the scale, this movable part cooperating with a notch provided in the upper part of the cutout of the rod to maintain the upper arm of the scale in

pressed position.

  The additional moving part mounted on the rocker makes it possible to lock the rocker in the pressed position, i.e. to prevent the automatic return of the

  rod in inclined position locked during a fle-

leg xion.

  The moving part can be sliding in translation or

  or have a combined movement of rota-

tion and translation.

  The accompanying drawing shows, by way of example, a

embodiment of the invention.

  Figure i is a partial view in vertical section of a ski boot showing the locked rocker

in the on position.

  Figure 2 is an enlarged detail of the

  switches to the unlocked position.

  The shoe shown is similar to the shoe described in document EP-A-0 286 586. It comprises a lower part 1 surrounding the foot and the heel and on which is articulated a rod made up of two parts, namely an articulated collar 2 on part 1 by means of two rivets 3 and a stirrup 4 located below the collar 2 and articulated on part 1 by means of 2 rivets 5. The collar 2 and the stirrup 4 are

  interconnected by a connecting device 6 of lon-

  adjustable hinge articulated in two points 7 and 8. A rocker 9 is articulated in a cutout 11 of the stirrup 4 around an axis 10. A spring 12 mounted between the bottom of the cutout and the upper arm 9a of the rocker a

  tendency to maintain the lower arm 9b of this lower

  abuts against the lower part 1 of the shoe as shown in FIG. 2. When the upper of the shoe is inclined forward, the end of the lower arm 9b of the rocker 9 abuts against a stop 13 formed on the part lower 1 of the shoe thus holding the upper of the shoe in

  a tilted forward position.

  The upper arm 9a of the rocker 9 has a housing

  rectangular 14 communicating with the upper end

  of the rocker by a slot 15. In this housing

  ment 14 is mounted a sliding part 16 having a part in the form of a rectangular plate whose thickness corresponds to the width of the slot 15 and

  a portion 16a in the form of a ridged button slightly protruding

  The back of the rocker 9. The moving part 16 pre-

  further feels a passage 17 cooperating with a recess 18

provided in the scale.

  The moving part 16 constitutes a lock. In the posi-

  tion shown in Figure 2 part 16 is in re-

  line in the rocker 9. By pressing the button 16a and simultaneously pushing it up in the direction of the arrow, the part 16 comes out of the rocker at the upper end and engages under a notch 19 provided in the upper part of the cutout 11 of the stirrup 4 as shown in Figure 1. The rocker 9 is then locked in this position and the end of the lower arm 9b of the rocker can pass over the stop 13, allowing the rod to rise vertically and to oscillate freely around

  of its joints 3 and 5. The skier can therefore walk

  expensive without risk that the rod will lock again

  by itself in an inclined position. Room 16 is main-

  held in this position by the boss 17 engaged in the recess 18. The part 16 and, if applicable, the rocker

  9, are preferably made of synthetic material.

  To return the shoe to the descent position, it

  just push the part 16 downwards and

chir the leg.

  The piece 16 could of course be mounted on a rod in one piece like that of the shoe

  described in document EP-A-0 086 908.

  In addition, the scale 9 could be equipped with a ver-

  eccentric rotary wheel or lock moving in

translation and rotation.

  The stop 13 could consist of a small

  metal bracket attached to the hull.
