Description

Shoe, in particular alpine ski boot

The invention relates to a shoe, in particular alpine ski boot, with a substantially dimensionally stable cuff extending from an attachment to a shaft to a calf area of a user, one extending from its lower end to be disposed in the cuff to its upper end at least partially wedge-shaped widening insert part is provided, which is provided for receiving in a calf portion of the sleeve. Furthermore, the invention relates to an insert for the shoe according to the invention.

A wide variety of inserts are known from the prior art, which are used in particular in alpine ski boots in the calf-side upper end of the sleeve. Such insert parts have in particular two functions: On the one hand, the insert parts are provided for adapting the shoes to the height of the user of the shoe, while larger persons can insert the insert in a higher, ie from the cuff, to one On the other hand, these inserts also serve to increase the template angle of the lower leg relative to a vertical plane, which is particularly advantageous for persons with relatively slender calves.

In such a known insert part is shown schematically in Figs. La and lb, from which it is apparent that in a lower position with such wedge-shaped inserts a larger template angle of the lower leg is effected, since the distance x between the support surface for the calf of the insert part and the diametrically opposite portion of the sleeve is less than in the one shown in Fig. Lb

extended or upper position. In the upper position shown in Fig. Lb the user receives a better relation to the lower leg length support, but at the same time the template angle is lower compared to a vertical plane and the distance x 'relative to the position shown in Fig. La larger, so a user disadvantageously, a lesser draft is given, whereby the turn initiation is difficult in alpine skiing.

From the state of the art, numerous relatively elaborately designed mechanisms for setting different template angles, for example, from FR 2 910 245 A, are further

EP 724 850 A and EP 467 142 AI known.

In DE 39 35 262 AI a ski boot is described with a attached to the shell spoiler, which is adjustable by means of adjusting devices in two mutually perpendicular directions.

From US 5,490,337 a ski boot with a pivotable spoiler is known.

The aim of the present invention is to provide a shoe according to the above-mentioned type, in which the user does not have to choose between an improved rear support and a desired template, but with which, especially tall people, a secure support to the rear and at the same time the desired template angle is offered.

According to the invention this is achieved in that the sleeve in the provided for receiving the insert calf portion has a material recess in which the wedge-shaped insert is at least partially received in a lower position, wherein in an upper position of the insert part is arranged such that the material recess below Training a cavity is bridged by the insert.

By receiving the wedge-shaped insert part in a material recess of the sleeve in a lower position and the bridging of this recess in the upper position occurring in known inserts adverse effect that automatically reduces the template angle is increased by increasing the insert, avoided. Depending on the type or depth of the material recess, the opening angle of the wedge-shaped insert part and the thickness of the sleeve in the upper end region, it is thus possible that in an upper position of the insert, the user even a larger template angle is offered as in a lower position.

In particular, it is thus advantageous if the template angle between a plane passing through a rear shoe end vertical plane and a directed into the interior of the cuff contact surface of the insert in the upper position is at least as large, in particular the same size, as in the lower position. Thus, by means of the insert part, the desired template angle for the user can be set, and by offsetting the insert part from a lower position to an upper position, the rearward support can be improved without, however, significantly changing the user's desired original angle.

To signal to the user in a simple manner that the insert is arranged in the desired lower or upper position, it is advantageous if the insert has at least one inserted in the cuff state on a side facing the sleeve side positioning. Of course, several lower or upper positions or any intermediate positions may be provided. If no such positioning is provided and the insert is held in a different manner to the cuff, in particular a continuous positioning in various positions between the lower and the upper position can be carried out.

If the collar has an opening, in particular through opening, for receiving the positioning element in the lower position of the insert part, it is possible by inserting the

Positioning element in the opening in a simple manner, the position of the insert are set in the lower position; at the same time the insert is held by the positive connection between the positioning and the opening. In order to easily determine the upper position, it is advantageous if the positioning element rests in the upper position on the upper edge of the sleeve. In order to ensure a secure fit of the insert part and in particular to avoid unwanted twisting of the insert part, it is advantageous if two spaced-apart positioning elements are provided.

With regard to a material-saving configuration, it is favorable if the insert part has at least one wedge-shaped widening web on the side facing the sleeve. For the wedge-shaped widening webs or the desired template angle is thus ensured without a full contact surface between the sleeve and the rest of the insert is required.

Since above the positioning of the insert part anyway is not provided for determining the original angle, it is sufficient if two widening towards the positioning wedge-shaped webs are provided, wherein the positioning each project beyond the end of the associated web.

With regard to a suitable form-fitting reception of the insert part in the lower position, it is advantageous if the material recess (s) for receiving the web or the webs is or are designed accordingly.

Tests have shown that it is favorable for achieving a user-friendly template angle when the wedge-shaped insert part, in particular in the region of the webs, an opening angle between 10 ° and 20 °, in particular of substantially 15 °.

In order to ensure sufficient dimensional stability of the sleeve, it is advantageous if the cuff-forming material made of thermoplastic material, in particular thermoplastic polyurethane with degrees of hardness of preferably 50 to 70 Shore D, or polyamide elastomer with degrees of hardness of preferably 50 to 70 Shore D. , or is glass fiber or carbon fiber reinforced plastic ^¬ ver.

If the insert is made of thermoplastic or fiberglass or carbon fiber reinforced plastic, although no fundamental restriction to a particular material is provided for this part, a cost-effective simple production and a sufficient stability of the insert part is ensured.

The invention will be explained in more detail with reference to a preferred embodiment shown in the drawings, to which, however, it should not be limited. In detail, in the drawings:

FIG. 7 shows a view of the back side of the insert part facing the sleeve; FIG. and

8 is a sectional view along the line VI I I -VI I I in Fig. 7.

As already mentioned, a cuff of a shoe with a known insert part is shown in FIGS. 1a and 1b, the basic mode of operation of such insert parts having already been described above. FIG. 2 shows a side view of a shoe 1 according to the invention with an insert part 2, over which an original angle α can be seen between a vertical plane 3 'running through a heel shoulder 3 and a front contact surface 2' of the insert part 2. This template angle α is given not only in the lower position shown in Fig. 2, but is also substantially retained upon displacement of the insert 2 into an upper position (see Fig. 6).

As can be seen in FIGS. 2 and 3, the insert part 2 is provided in its functional position in a rear calf area 4 'of a sleeve 4 connected to a shaft 1' of the shoe 1. In the alpine ski boot shown in FIGS. 2 and 3, a substantially rigid shaft 1 'and the dimensionally stable cuff are

4 connected to each other via a swivel joint 6. The insert 2 is in this case between the dimensionally stable sleeve 4, which preferably consists of thermoplastic or fiberglass or carbon fiber reinforced plastic, and arranged (not shown) padded liner.

In Fig. 5, the connection between the sleeve 4 and the insert part 2 in a lower position can be seen in detail. Here, the sleeve 4 has at least one material recess 7, in which a portion of the wedge-shaped insert part 2 is at least partially received in the lower position. For the sake of a simple expedient positioning, the insert part 2 has two positioning elements 8 projecting substantially vertically from its rear side, which in the lower position are accommodated in the passage 4 in a passage opening 9 (see FIG. Additionally (or alternatively) to the

Positioning elements 8 may also be provided a fastening screw 10 which is received in a slot 11 of the insert part 2; in the dissolved state of the screw 10, the insert part 2 can thus be moved in the longitudinal direction of the elongated hole 11 relative to the sleeve 4. When tightening the screw 10, the position of the insert part 2 with respect to the sleeve

5 reliably secured.

As a comparison of FIGS. 5 and 6 between the lower and the Upper position shows is - since in the lower position of the insert part 2 is at least partially received in the material recess 7 and in the upper position, however, the material recess 7 bridges the formation of a cavity - the template angle α shown in Fig. 1 between a vertical plane 'and the contact surface 2' of the insert part 2 ^{essenli ¬} chen maintained. Thus, although a portion of the wedge-shaped insert part 2 is arranged in the upper position - compared to the lower position - lesser wall thickness at the same height, thus, the distance x described in connection with the prior art remains substantially constant. Accordingly, if a tall person desires to increase the rearward stability, the original angle α is substantially maintained, and thus the ability to induce the turn is not diminished. Depending on the design of the opening angle ß of the wedge-shaped insert part 2, the material recess 7 and in particular the upper end portion of the sleeve 4 in the contact region of the insert part 2 in the upper position and a larger template angle can be achieved in the upper position.

As can be seen in particular in FIGS. 7 and 8, the insert part 2 can have projecting webs 12, so that the side of the insert part 2 facing the sleeve 4 does not rest against the entire surface thereof, but only in the area of the webs 12; Accordingly, the material recesses 7 of the sleeve 4 can be provided only in the region of the webs 12. Essential to the invention is only that with the help of

According to the invention, an increase in the stability towards the rear by the upwardly displacing insert part 2 is not necessarily accompanied by a reduction in the original angle α due to the tapering wedge shape of the insert part 2. Rather, depending on the dimensions of the wedge-shaped insert part 2, the recess or material recess of the sleeve 4 and the adjoining the recess end portion of the sleeve 4 of the template angle α in an upper position of the. Retain insert 2 or increased if necessary.
