^ Ski boot / *

The invention "relates to a ski boot, instes special with one Shank designed as a cast part, the neck of which is opposite the The lower part of the shaft can be bent, with a flexible insert piece at the transition between these shaft parts for relief the bendability of the shaft neck gate is seen.

When using ski boots it is necessary that the part of the shaft comprising the lower leg, called the shaft neck, can be bent in relation to the lower part of the shaft. Through this the skier should have the necessary presentation or stoop when skiing can take and it should be easier to walk.

In order to achieve the above-mentioned bendability of the shaft neck with respect to the shaft lower part, in the case of ski boots, the method introduced at the beginning described type a flexible insert between these shaft parts -provided, which is made of a relatively soft, resilient Material is made and can therefore lay in folds when the shaft neck is bent. At this sestal

• · I · ■ ·

However, there is no guarantee that the folds will follow a regular course, so that there is always a risk there is that pressing bulges arise on the foot. Above all, however, these are allowed with the well-known ski boots Art the flexible inserts do not exceed a certain size if the snug fit of the Ski boots should not be impaired, as a result! has that the expansion reserve of the insert is relatively small is.

Object of the present invention is thus to design ski boots of the inputs mentioned genus, that they have a greater elongation reserve for the deflection of the shaft neck relative to the shaft bottom part, without thereby affecting the snug fit or the formation is favored by ί pressing beads. According to the invention, this object is achieved in that the insert piece is designed in one piece with the shaft parts and there are accordion folds formed in the insert piece. "?

Due to the inventive training, the regular course of the folds of the insert is already through the Her- ^ Positioning process preformed. This means that no part of the]% ' Use piece during the turning process with regard to the training ^ - | si favors a fold, which is the case with the well-known ski boots Occurrence of pressing bulges could lead. Furthermore, there is no displacement of the insert during the bending process in sighting on the foot or away from it, but the stretching is merely due to a mutual approach the accordion folds compensated «After all, the he— inventive training the advantage that through the pulling

monika folds in the event of sudden impacts Lead bending of the shaft neck with respect to the shaft lower part, a certain shock absorber effect is exerted.

According to a further feature of the present invention it is provided that the accordion folds of the insert converge towards the quarter sides of the shaft. Through this the different expansion path in the longitudinal direction of the gaps is better taken into account.

According to another development of the concept of the invention, the insert is formed on a closing tab of the shaft and can be suspended from a holding part arranged on the side of the shaft.

In the drawing is an embodiment of an inventive Ski boots shown in a side view, from which further features, which shape the invention, emerge are.

The shaft of the ski boot has an insert 1 in the heel area at the level of the butt joint . Stalteter insert 2 is formed on the closing flap 3 of the shaft extending over the instep. The column insert 2 has a protruding opposite the closing flap 3 -.- of the actuating end 2 * for grasping the closing flap when the end is hooked in 2 ¹ in a holder arranged on the side of the shaft. In the embodiment shown in the drawing, this consists of a push-button device, where the button 4 is located on the actuating end 2 * of the pleat insert 2 and the counterpart to this is located on an elastic attachment 5 on the side of the shaft, which

is attached to the shaft by means of the seams 6. The attachment 5 can, for example, consist of a rubber thread streaked with it Textile fabric exist, the main direction of stretching in the direction of the in the closed position at the. of the fold insert 2 acting tensile forces should run.

This and the rotatable mounting of the push button 4, the freedom of movement of the lower leg is further demanded "Instead of a push-button device can of course any other purpose corresponding rotary joint for the mounting of the operating end of the pleat insert 2 used two ^first

As can be seen from the drawing, the folds converge the inserts 1, 2 to the quarter sides of the shaft. Included the folds of the two inserts run towards each other, so that their ends lying on the quarters sides at least approximately coincide. This will create a Avoided lever torque from the forces derived in the direction of the folds towards the shaft sides.

The other apparent from the drawing closure means for holding the closing flap 3 in the closed position '^ “Do not belong to the invention and therefore do not need ^ - ^ j to be described. - -

The invention is not limited to the following claims. It includes all features from the above description and the drawing that are based on the Prior art are obviously inventive.
