DE1916754A1 - Ski boot for safety bindings - Google Patents

Description

The invention relates to a ski boot that is on a Ski can be fixed with a safety binding.

The safety with which such a ski boot slides out of the connection with the ski as soon as a load occurs - for example due to a fall - due to which the safety binding is supposed to open, is essentially determined by the fact that the ski boot is good on the tread of the ski This is by far not always the case, especially with modern ski boots with molded rubber soles, and efforts have already been made to equip the ski with special sliding surfaces on which the outer soles of the ski boots slide well. The attachment of such sliding surfaces is relatively complex and requires additional holes in the ski, which is perceived as disadvantageous. ^Ä

The invention is based on the object) to provide a smoothly sliding system between ski and ski boot without having to Ski itself changes should be made.

! The object is inventively achieved in that at the 'bottom sole surface of the outsole of a ski boot for the safe-from sliding out of the opening in the Hotfall connection with the ski at least in the ball region of a slide. zone is provided, which has a greater sliding ability than the rest of the sole fly with respect to the tread surface of the ski resting on the outsole.

The different slide well can be described by the coefficient of friction, which have the surface area on one hand and the rest of the sole surface with the other part of the tread of the Skig "It is assumed that the areas ₉ have no sharp-edged configurations ,? which are able to penetrate the tread, which would stand in the way of a comparison of the sliding abilities with the help of the coefficient of friction and would otherwise run counter to the purpose of the invention. It must be taken into account that sharp-edged profiles on relatively soft sole surfaces, for example a molded rubber shoe bottom, deform to form a wider contact surface when they come into contact with the tread surface and thus do not penetrate the tread surface. If the material is correspondingly harder & e% hot zone, square j * profiles, on the other hand, must be avoided? S iroralieraia,

Such a sliding zone can in principle be created by applying substances capable of sliding on a corresponding area of the sole surface. Layers of material with increased sliding ability can be glued or vulcanized onto the corresponding area of the sole. In particular, thicker sliding layers are expediently embedded in the outsole, see above that the surface of the sliding layer forming the sliding zone and the rest of the outsole surface in the case of a non-arched sole Ibtne educates.

The sliding zone is preferred in the ball area of the sole, see, because this is where the greatest pressure forces are between the sole surface and the step surface when the solution is between the ski « The zone can be designed as a strip that extends from the inner ball area to the ball outer area, but it can also occur Be il-crescent-shaped and in particular in extend the outer ball area of the sole surface.

The rubber outsole, denoted as a whole by 1, is cast onto the upper 2 of the ski boot (FIG. 2) and provided with a profile A on its outsole surface 3 (FIG. 1). A sliding layer 5 is cast into the outsole 1, which is anchored in the sole with projections 6. The bottom surface of the sliding layer 5 is provided with a ribbed profiling 7 and ends flush with the profiled running surface 3 of the outsole 1. The protruding hips of the profiling 7 are so wide on their bottom back

designed flat so that the ribs cannot penetrate the step surface of the ski. The back surfaces 8 of the ribs overall form the contact surface between the ski boot and the step surface of the ski, which due to the between these Surface 8 and the tread surface have a low coefficient of friction allows the ski boot to slide safely out of the binding. The reduction in the coefficient of friction between the back surfaces 8 of the sliding layer 5 and the step surface of the ski in relation to the coefficient of friction, that occurs between the surface of the outsole and the tread, is due to the choice of material of the sliding layer 5. These In the present case, sliding layer 5 consists of a relatively hard plastic.

Figure 1 shows the bottom surface of the sliding layer 5 » which forms the sliding zone 9 and extends across the inner and outer ball area as a wide strip across the outsole the sole extends across. Of course is also a different arrangement and shape of the sliding layer 5 and thus the sliding zone 9 is conceivable. In particular, the The portion of the total outsole surface taken up by the sliding zone 9 may be significantly larger or smaller than shown here.

Profiling 4, not shown in the figure, of the running sole surface 5, so that no gradations appear across the running sole surface, which prevent the entire profiled sole surface from resting equally on the respective base. This achieves ₉ that, when the pressure load between ski and ski boot occurs, particularly in the ball area, for a loosening of the binding in a vertical case, the back surfaces 8 of the ski pads are primarily in contact with the ski area, while the ski is in a normal stance and in particular also ice when the skis are put down.
