DESCRIPTION:
BRIEF SUMMARY
BACKGROUND AND SUMMARY OF THE INVENTION
The invention relates to a device for adjusting the forward lean of the upper of a ski boot with a pull and pressure piece, which is supported on the bottom shell and the upper or the cuff, and the distance of the supporting surfaces on the pull and pressure piece interacting with the upper or the cuff is adjustable for support on the bottom shell in lengthwise direction of the pull and pressure piece.
Devices for adjusting the forward lean of the upper of a ski boot of the above-mentioned type are described, for example, in AT-PS 384 351. In this known design, elastomer components were placed inside a housing designed in the manner of a shock absorber, and the change of the basic setting for the forward lean of the upper becomes possible because the component was released completely from the anchorings, whereupon a cuff was screwed on a male thread by rotating the housing of the shock-damping component, so that the effective length and thus the basic setting of the forward lean could be changed. Altogether, the damping component according to Austrian patent 384 351 represented a relatively expensive and complicated component, in which a basic change of the damping properties for the forward-lean delimitation was possible only by complete dismantling of the component and replacement of damping elements or springs incorporated in the component.
The object of the invention now is to provide a simple device, which can be placed in the smallest space, of the above-mentioned type, with which the possibility is provided to change in a simple way the damping properties starting from a basic setting of the desired forward lean of the upper. Special importance is attached to the circumstance that not only a spring pretension is to be changeable, as is possible in a number of forward-lean delimitations, but that actually the damping can be matched exactly to the respective requirements without big components being necessary for this purpose. To achieve this object, the device according to the invention basically consists in that the supporting surfaces interacting with the upper or the cuff interact through the interposition of a damping element made from elastomeric plastic or rubber with an upper and a lower stop face on the upper or the cuff. Since a relatively small damping element is placed directly between stop faces on the upper or the cuff and supporting surfaces of the pull and pressure piece, a damping element, accessible and exchangeable in a simple way, is made possible, and since the supporting surfaces on the pull and pressure piece are adjustable in the lengthwise direction of the pull and pressure piece, a simple forward-lean adjustment is made possible in a conventional way. The arrangement of an easily accessible damping element directly between the surfaces interacting with one another in this case in no way affects the simple adjustment of the forward lean in a conventional way, and in addition, through the interposition of such a damping component, a slight change of the damping properties is made possible by exchange of the component or other orientation of the component.
According to a preferred further development of the device according to the invention, the design is made so that the supporting surfaces, interacting with the upper or the cuff, are made by a nut that can be rotated on a male thread of the pull and pressure piece, in particular a milled nut. In this way, as known from other forward-lean adjustments, the basic setting of the forward lean can be changed by simple rotation of a nut, in particular a milled nut, and the damping properties starting from the basic setting selected in each case are no longer dependent on the selection of the corresponding material for the interconnected damping element or on the orientation of the damping element in the free space between the nut that can be rotated and the counterstop faces on the upper or the cuff.
According to an advantageous further development of the device according to the invention, the
