Ski boot

The invention relates to a ski boot with at least t

a limited pivoting relative to the shell j

Since the so-called shell shoes with or without their own >

Inner shoe is the connection between shoe (

and bindings and thus skis have become much stiffer. |

When walking on the one hand, when driving sensitively on the other- |

On the one hand, the rigidity brings considerable disadvantages I

with itself. 1

Attempts have already been made to split the shoe, I

namely &iacgr;&eegr; a shell part and cuff upper part |

(for rear entry models consisting of the lower part, j

To allow at least a certain degree of mobility, j

the cuff upper parts were riveted on (fixed riveting).

In further development, especially with very high- |

high-quality ski boots are already available on the market

The invention is based on the task of enabling the upper shafts of a shoe/ski boot to be adjusted automatically, i.e. freely, while skiing, in order to avoid the ski becoming jammed, but also the shinbone becoming "jammed" in the shoe, sore ankles and knee and hoof wear.

This is achieved according to the invention in a ski boot of the type mentioned at the beginning in that at least one of these two pivot or rotary bearings S is freely displaceable in a translational manner .

\ This means that there are two price levels: namely that of

In particular, the slots arranged in the shell are inclined at an angle of 65 to 85°, in particular 70 to 80°, to enable these translational movements.

Rotation (pivoting bearing between e.g. sleeve and shell) | 'and translation: movement of the pivot bearing along a slot.

According to an advantageous embodiment, both pivot bearings (on both sides of the ankle) are in a J

such a slot can be moved.

Due to the free sliding of the pivot bearing(s), |

this free movement: the cuff has no fixed |

Pivot point no longer; free movement of the camp is possible.

The slot can be arranged at a certain angle (with conventional ski boots with overlapping cuffs), above all diagonally forwards. The angle depends primarily on the so-called heel drop, i.e. the angle of the sole of the foot that results from the fact that the heel is raised when wearing mountain boots, ski boots and ice skating boots. Of course, the angle depends on the so-called heel drop.

The cuff is dependent on the presentation of the cuff. Preferably, the

Preferably, the slots are parallel to the forward angle of the shaft,

In contrast, according to a special embodiment, in the case of ski boot models with rear entry, which are generally equipped with a rear flap and a front part , it is provided that these angles are essentially vertical.

can move in a translational manner, an automatic spirit level-like self-adjustment of the cuff parts relative to the shell is ensured. This also results in an automatic adjustment to the individual calf shape (the right boot can adjust itself completely independently of the left boot, depending on the required angle of the leg. This is particularly important when the lower legs are differently shaped or have different contours. Incorrect adjustments, painful ankles, knee and hip wear are avoided. The "correct" i.e. natural adjustment of the ski boot on the ski is achieved, which prevents the skis from accidentally jamming. The natural adjustment of the upper shaft prevents the upper shaft from being adjusted incorrectly i.e. not at the correct angle.

It has been shown that the freely sliding pivot bearings enable a much better and more harmonious bending movement in and with the ski boot.

Until now, the strength of the riveting was variable (from very tight on one side to relatively loose on the other side of the ski boot) and very frequent. These phenomena, which lead to uneven bending movements due to different riveting, are a thing of the past with the proposal after the invention.

&Idigr; There is always a full pressure of the entire sole of the foot on the heel or, in the boot, on the ski due to the automatically occurring natural and automatically correct angle of the foot. Since the leg is no longer tilted in the boot, the ski is no longer tilted incorrectly either.

The pivot bearings, which can be designed in any way, can be further developed according to a further embodiment,

bar, for example by means of step-by-step training* According to a special embodiment that is not to be regarded as restrictive, the threads for the same screw bolt become narrower towards the end of the pivot bearing tension, thus offering greater screwing resistance.

An advantageous consequence of the measure according to the invention is that the bending movement can now be carried out in an orthopedically correct manner (whereas previously, when the upper shaft was firmly riveted with only one degree of freedom (rotation), locking and blocking of the ankle joint could be observed).

The "moving pivot point", which is a free shaft suspension that adjusts itself, ensures a better edge feel. Because one of the pivot joints moves upwards, for example, the foot can always keep its pressure on the ski constant or adjusted in changing ground conditions, e.g. on bumpy slopes or uneven slopes (changes in slope angle). With rigid upper shafts that were also incorrectly positioned, the foot could not maintain contact with the snow or ice surface.
^y '

The continuous, automatic adjustment of the cuff ensures that the correct adjustment is always made; you can save yourself the need for newer canting adjustment designs, which are all very fragile. In addition, they protrude from the shaft in a bulky manner and break in the event of a fall or contact, or get lost.

.Compared to the previous (rigid) adjustment options, there is for the first time a real upper shaft correction, ' IC as the previous adjustment options only brought about an angle change by accepting shaft tension, but only on the outside, in any case no adjustment on the inside of the foot. _;

In a further development of the invention, it is possible to produce a construction that is only in principle like this invention, but is actually simpler, and then to fix the naturally found unique position. , Another advantage of all measures according to the invention is that there are no protruding bulky parts. In this case, a slot inclination of 10 to 15° (against the vertical) is selected.

Of course, kinematic reversal is also possible (slot in the sleeve; bearing in the shell). ?

On the other hand, it is also possible to use the I

A slot on one of the two shoe parts can be used to attach a slide track with an inclination corresponding to the orientation of the shoe, in which the head of the rotary bearing can then be moved. The slide track does not even have to be firmly attached to the shell. The slide track itself can also be rotatable, so that a third degree of freedom is created.

If the material is not sufficiently abrasion-resistant, an abrasion-resistant sleeve is provided that surrounds the slot.

The sleeve can also be made by flanging the slot on both sides. However, it is also possible to have a head part of the sleeve on the outside and a plug part of the sleeve passing through the slot.

The respective pivot bearing can optionally be complementary components that can be plugged into one another and are held in place by screw-in retaining pins.

The components that can be plugged into one another can consist of a round disk that is flush with the outside of the ski boot and has two parallel plug-in feet, with the other component consisting of a disk that is essentially flush with the inside of the shell and has plug-in feet that are complementary to the first one, as well as the screw-in Allen key retaining pin. It is also possible to slide a single plug-in foot designed as a central web between the plug-in feet of the first disk.

Fig. 1 shows a schematic representation of a ski boot 10, namely the lower shell part 12, in which a slot 14 is made. The slot is only shown schematically. It can be flanged with a sleeve if necessary. A pivot bearing 16 can be seen schematically in the slot 14. This pivot bearing is designed in such a way that it connects the shell 12 (the lower part of the ski boot) to one or more cuffs (not shown). It is important that the pivot bearing can be freely moved in the slot.

According to the illustration, the slot runs parallel to the template 18. In any case, the slot is inclined at a significant angle to the vertical. The determination is made according to the type of model (overlapping cuffs or rear entry) and

depending on the model (beginner model or racing model) .

the advantages mentioned above only occur in part.

Fig. 2 shows an example embodiment of an abrasion-resistant sleeve 20 which, for example, encloses the slot 14 of Fig. 1. The sleeve itself has a flange 22 surrounding the slot and a bushing part 24 with which it extends through the slot. This sleeve then forms the actual guide for the ' 'pivot bearing.

Figures 3 to 5 deal with an embodiment for the pivot bearing,

According to Fig. 3, a flat disk 30 with recesses 32, guide part 34 and parallel plug-in parts 36 (so-called plug-in feet) is provided.

Fig. 4 shows a counter disk '\0 with a central web 46 (which can be sunk into the disk of Fig. 3) which has a threaded bore 4.

Fig. 5 finally shows an assembly example, where the sleeve 14 is only indicated and the two plug-in parts are shown in the inserted state. The reference numerals are the same as in the previous figures, where the thread is only indicated, screwed with Allen key 48.

Another advantage is that the shoe provides cushioning, for example from very hard impacts on an icy slope, because the different parts of the shoe can initially move relative to one another.

The slots or the protective plate will always be located in the stiffest part of the shoe and can already be inserted and molded during the injection molding process. 35

Figures 6 and 7 show a further design of a rear entry model. Here you can see that, in a manner known per se for rear entry models, the pivot bearing is moved to the rear lower area of the lower step 50. The translation slot(s) 58, in which the pivot bearing(s) 56 are slidably mounted, are arranged essentially vertically. The so-called sleeve part 52 and the rear entry flap 54 are hinged to the lower step 50 via the pivot bearing. The pivot bearing 56 can again be moved freely in the slot 58, as indicated by the double arrow in Fig. 6. Fig. 7 shows in section how the longitudinal slots 58 are formed in the lower step 50, in that the bolt of the pivot bearing 56 is slidably mounted in each case. Attached to the swivel bearing is the sleeve part 52 on the outside and the rear entry flap 54 on the inside. This has the advantage above all that the rear flap can adjust separately to the inclination of the lower leg.

In a further development of the invention, it is also possible to attach two joints, a fixed joint and a sliding joint that can be moved in the slot. All combination options are possible in this way. In particular, the tailgate can be hinged via the sliding bearings, which is also advantageous for ice skating boots due to the better shaft angle adjustment. For all the designs described here, especially for housing designs (rear entry models) with rigid shaft uppers, it is important that the upper shafts can now adapt to the respective leg anatomy, caused essentially by the moving pivot point.

-&igr;&ogr;&iacgr; With the synthetic mountain boots, the translational movement of the upper parts of the shaft provides a natural step. If the mountain boot tilts, this has a devastating effect, especially when walking in a squat position, as the familiar shoes will force you out of position. And even the

can lose balance. The same applies to ski boots.

The fact that there are also ice skating boots that extend well over the ankle also enables a leg-friendly, i.e. angle-correct, solution when standing on the blades.
