Abstract

In this ski boot of the type comprising a shell (2), a quarter (3) articulated on the shell, and a rear part of the rod (4), said rear part (4) is associated with a part of the shell (2 ) located downwards, by an articulated connection (4a) in the heel region of said shell.

Description

The present invention relates to a shoe

  sour ski, comprising a quarter enveloping towards the front and at least partially around the instep of the shell of the boot, and a rear part of the upper, both associated with the shell of the boot by an articulated connection in order to be able to move away one

compared to each other.

  Ski boots of the type described above have been favorably received on the market, because they are convenient to put on and take off, and which have fastening means which are relatively

easy to adjust.

  These shoes usually include a shell on which a quarter and a rear part of the upper are articulated The quarter and the rear part

  can be moved away from each other so that the shoe

sure to be easier to adjust.

  In prior art shoes, the part

  rear tie rod is mounted on the same joint as the quarter or, alternatively, on two axes arranged

  further back from said joint.

  This design is suitable for both

  shoes adjustable from the back and for those adjusted

  tables from the middle and from above In particular

  when the shoe is designed to adjust by the rear

  We may encounter some drawbacks.

  A drawback resulting from the above first method of fixing the rear part of the rod to

  the shell, is that the angular displacement of the par-

  tie back to the open position is limited by

  the lower edge of said rear part, which meets

  be the heel part of the shell; move

  limited angularity of the rear part provides

  tation at the opening angle thereof relative to the

  neighborhood and, therefore, a rear adjustment opening

  of limited width which makes it difficult to penetrate

tion of the foot in the shell.

  The second fixation process, i.e.

  it in which the rear part of the rod is articulated by means of axes other than those of the quarter, partially remedies the aforementioned drawback, but reduces the degree of freedom of the angular displacement of the quarter with respect to the shell, by the simple fact that the axes of articulation of the quarter and the rear part

are different.

  Other suggestions to associate the party

  back of stem to quarter, and the latter to the shell-

  while, on the one hand, remedying the inconveniences

  above, on the other hand, are liable to

  ner a risk that, when the quarter is bent forward, the corresponding equal inclination of the rear part associated with it can cause an elevation movement of the heel of the skier's foot inside

the shoe.

  The object of the invention is to produce a shoe

  sure ski with construction features

  tion and performance likely to overcome the in-

  conveniences of the aforementioned prior art.

  The object of the invention for this purpose is a shoe

  sour ski of the aforementioned type, characterized in that the rear part of the upper is associated downwards with a part of the shell of the boot, by a connection

  articulated located in the heel region of said co-

  keel. Advantageously, the rear part of the rod came integrally with the rascal, to which

  it is connected via an inferior part

  narrow, having a configuration substantially similar to a band, and transversely wavy so as

to be flexible and foldable.

  Other features and advantages of the

  vention will appear during the description which goes

  follow, made with reference to the accompanying drawings, given solely by way of example, and in which: Figs 1 and 2 are perspective views showing one side, and the opposite side of a ski boot

  according to the invention, in the closed and open position

  partial green, respectively; Fig 3 shows a detail of the ski boot shown in Figures 1 and 2;

  Fig 4 shows a variant of the detail shown

tee in Fig 3;

  Fig 5 shows another variant of the detail re-

shown in Fig 3.

  Referring to the drawings, a ski boot according to the invention, designated as a whole by the

  reference 1, includes a shell 2 on the oppo-

  sés of which is articulated a quarter 3, by means

  axes 5 located at the location of the so-called mal-

  leolar Quarter 3 at least partially envelops-

  part of the instep of the shell 2 and is open at the rear by a cutout 3 a The reference 4 designates a rear part of the rod, which cooperates with the

  quarter 3 to surround and enclose the parts of the neck

  instep and leg of an internal shoe 6.

  7 shows the front fixing devices, which are mounted on opposite parts of the shell 2, and the reference 8 designates as a whole

  fixing and tensioning means known in them

  mes, for quarter 3 and rear part 4 Of a

  more particularly, these means are of the type used

  sant legs, loops cooperating with small bosses having several hooks, and levers

Of voltage.

  The rear part 4 is associated with the shell 2, towards the bottom of the shoe, by means of a link articulated in the transverse direction, in a region 9 of the shell situated behind the heel, at the location of the lower side 2 b of the cutout 2 a that each shell 2 has at the rear.

  According to the preferred embodiment (shown

  felt in Fig 3), the rear part 4 is integral with the

  shell 2, to which it is connected by means of

  diary of a narrow part 4 a, having roughly the form

  me of a band of limited width, so as to make it

flexible and foldable.

  In another * embodiment, shown in FIG. 4, the strip 4a is corrugated transversely so as to

  to give it a better ability to flex.

  In a variant shown in FIG. 5, the rear part 4 is associated with the heel region of the shell 2 by means of a hinge 10 proper,

  of the type with two wings 11,12 articulated on an axis 13.

  Due to the particular "connection" of the rear part 4 with the shell 2 and the particular position of this connection, the part 4 is angularly movable backwards with the desired angular amplitude. It follows that, in comparison with this

  that it was possible to obtain so far, the

  possible relative temement of the rear part of the rod

  and the neighborhood is greatly increased.

  In addition, when during skiing, the quarter is tilted forward (bending around the ankle), it is not followed by the rear part, which is fixed to the shell of the boot Consequently, no stress is applied to the skier's foot, which tends to lift the heel of the foot inside the shoe. Of course, the invention is not limited to the embodiments shown and described, which have not

  have been given only as examples.

  before being brought to it all fall within the framework of

appended claims.
