Description

Patent - Description of ski boots with forward-backward movement Superiority.

The present invention has set itself the task of having ski boots forwards-backwards movable upper shaft to adapt to the downhill conditions. It can happen, depending on the circumstances, that the runner is in the upper part of a descent Turns in a fairly upright position, with little forward (of the body's center of gravity) executes, but in the final part has to cross a bumpy slope, whereby for him Modern jet swing with knees bent forward, but with the body center of gravity back would be an advantage. A peculiarity of this posture is that the muscle groups heavily used, which are otherwise exercised when. As a result, means When driving like this, a firmly inclined heel support on the upper shaft is a large one Relief. Certain special boots have built-in supports, or adjustable reclining supports for different positions or areas, but is a changeover is only possible when the system is at a standstill.

For other ski boots that use a cuff-like waistband. it reduces the forces controlling and stressing the ski cm .. one and via one Transferring the movable heel support to the lower shaft, the author has a solution in his (German) patent application dated April 14, 1971 / April 19, 1971.

"Ski boots with a soft, flexible shaft" described.

Patent - Description of ski boots with forward-backward movement Superiority.

The present invention applies those results to ski mountaineering.

feld, the upper shaft by means of a joint or a similar acting Device is movably connected to the lower shaft. The decisive factor is that the transition from free mobility to a fixed attitude of the upper class also the later resetting to the initial state take place while driving can, caused by certain body movements of the runner, possibly under Participation of power stores and / or auxiliary energies.

In picture 1) 4 positions for the inclination of the upper shaft are shown; they have the following meaning; In the area 1 - 2 the upper shaft can be moved freely - with or without forward lean suspension; for normal downhill posture with little lean forward of the body's center of gravity.

In the case of 2, the upper leg is determined by presenting the knee in an incline favorable for jet turns; in the area 2 - 3 can be done several times "Rocking" i.e. further bending the knees forward this inclination can be increased, namely in stages, up to position 3, where the highest, permanently bearable forward inclination is reached is. - Position 4 corresponds to the highest, briefly achievable forward inclination.

An example is given in Figure 1).

Patent - Description of ski boots with forward-backward movement Superiority.

As the forward inclination increases, the knee lever K extends to the rigid position 2. By reaching into the grip knee lever G by hand, the w «z4 ++ lever \ bent again, and thus the fixed position can be canceled again.

Another kind of cancellation, without manual operation, just through extreme knee forward position up to position 4, in connection with an extremely deep "squat", is described by the author in his German patent application from 14/19 April 1971. "Ski boots with a soft, flexible shaft". There, in Fig. 9) and on sheet 8), a rocker arm is described which responds in position 4) and causes the reset.

In the present application, an arrangement is shown in Figure 2), in which a strut carries a slider q that slides in a guide F with the following Properties: In the 3 area 1 - 2 it can be moved freely in both directions.

Between 2 and 4 it is only flexible in the direction of increasing forward inclination, while it locks itself backwards, in the manner of the known freewheel constructions. The known means can be used to lift the block.

Fig. 3) shows an arrangement in which it is not subject to pressure Strive, special a pulling organ, the fixed adjustment of the forward position in position 2 guaranteed.

@ Here, too, the sliding piece Gl has limited freewheeling characteristics in the following sense: freely movable in the area of position 1 - 2; in the area movable from 2 - 3 - 4 with increasing forward inclination; opposite: blocked Zug-Organ can be used as a flexible rod (e.g. steel wire) BS, in a likewise flexible ear R guided, trained, and can be carried out to the sole insofar, when in the active case (fixed forward inclination) it is only subjected to tension, it can be dimensioned favorably, this means a minimum effort for the additional parts. This solution can also be used for the arrangement of heel supports like them in the author's patent application dated April 14/19, 1971, see p. 3, described i are9

Claims (2)

Patent - claims ski boots with forward-backward movable upper shaft. 1) Ski boots with an upper shaft that can be moved forwards and backwards, thereby marked that the upper shaft of the runner during the journey is temporarily in a @ Fixed position (s) brought, and can be made free again. @or several, ski boots according to claim i), characterized in that the manufacture and lifting of fixed positions) through certain body movements of the runner, with or without singing hoops by hand, with or without the help of power accumulators and / or auxiliary energies can be achieved. 3) ski boots according to 1) and 2), characterized in that although manufacture the fixed positions) of the upper stock a toggle lever arrangement (K) is used, with the knee lever being extended by the runner, and by short-term, extreme knee leaning forward, or other body movements to be flexed again. 4) ski boots according to 1) and 2), characterized in that after manufacture the first, permanent position through further measures of the runner further, permanent Settings, e.g. with increasing forward inclination of the upper class, can be produced. 5) ski boots according to 1) and 2) characterized in that the range of motion the upper shaft is characterized by the following positions of the upper shaft axis: Patent claims Ski boots with an upper shaft that can be moved forwards and backwards. Position lo upper shaft axis perpendicular to the lower edge of the ski, position 2nd axis leaned forward; first position, desirable for jet turns, position 30 highest continuous Tolerable forward inclination of the Onter thigh Position 4. "Briefly" "" "£) Ski boots according to -1) and 2), characterized in that to cancel fixed settings Elements with toggle switch properties are used. 7) ski boots according to claim 1) and. 2), characterized in that Organs with position-dependent variable freewheeling and locking properties are used will. 8) ski boots according to 1) and 2), characterized in that the sporty effective rieil of the upper shaft is given the simplified form of a heel support (St), such as it in the author's patent application dated April 14, 1971. is described - title: Ski boots with a soft, flexible shaft. 9) ski boots according to claim 1), 2), and 8), characterized in that the heel support (St), at its upper end with a collar encompassing the leg (B), in the case of fixed settings for the forward tilt, acts as a compression rod, which is held by a pulling organ, e.g. a flexible one, in one too flexible tube (R) guided rod (BS), whereby the pulling organ is attached in the lower shaft and can be pushed to the sole by means of additional tension straps.
