DE2807371A1 - Relative tilt adjustment for ski boot base and upper - consists of cam, pivot pin and handle with eccentrically positioned pivot points - Google Patents

Abstract

The base of a ski boot can be adjusted in relation to the upper by the upper being mounted on a pivot point on the base of the boot. At least one cam (3) has its pivot point in the base (1) or in the upper (2). The cam has at least one pivot pin (5) and a regulator piece (4) which may be in the form of a handle. The pin (5) and handle (4) and cam make up one unit preferably. The cam (3) can have any outer shape, such as round, elliptical with eccentrically positioned pivots points, angular preferably with rounded corners and with variable distances to the centre. The cam is mounted in a hole, partial hole or lengthwise hole.

Description

Device for adjusting the cuff

for the shell of a ski boot The invention relates to a device for adjusting the cuff to the shell of a ski boot, the cuff being tiltable is attached to the shell via a pivot point.

Devices for adjusting the cuff for the shell of a ski boot are known per se. These are, for example, slot or slot adjustments in the cuff like a zipper or

expensive separately riveted fittings are known that allow the cuff to be adjusted forwards by locking or adjusting the weight. The disadvantage here is that adjustment is usually not possible when the ski pants are closed is or are devices of this type expensive and often a hindrance. Also is making the adjustment very difficult, especially when the skier is wearing the ski boot.

The object of the invention is to provide a device of the generic type Art to produce in a simple and reliable working form that can cope with any load but withstands the simplified and compared to the conventional embodiments so that it is less prone to failure.

The task at hand is solved by at least one eccentric, its pivot point (bearing / pivot pin) in the shell or in the sleeve of the ski boot.

Such a device can simply be twisted into several Positions are spent so that differently large inclinations of the cuff can be adjusted to the shell by simply turning the eccentric.

Such an eccentric can consist of several parts, e.g. screwable getting produced. It is also essential to the invention that the eccentric as a Building unit can be created. Therefore, there are corresponding inventive measures required in order to be able to bring this structural unit into its pivot point (storage).

It is also essential to the invention that the distance between the shell and The surfaces causing the cuff preferably run in a straight line to one another (contact surface of the eccentric to at least one abutment is meant); this becomes an undesirable one Twisting of the eccentric while running or impacting, etc. prevented.

Further details of the invention emerge from the drawing - and Description, namely shows: Fig. 1 shows an embodiment in side view of an eccentric, FIG. 2 shows a plan view of FIG. 1, FIG. 3 shows another embodiment an eccentric and FIG. 4 shows a plan view according to FIG. 3 (all schematic).

The eccentric 3 according to FIGS. 1 and 2 consists of the surfaces 16, 17, 18 and 15, the transitions from surface to surface being rounded. The pivot 5 is arranged eccentrically so that each of the surfaces 15 to 18 is a different distance having. The pivot pin 5 is mounted in a partial bore in the sleeve 2 is introduced. In addition, there is an insertion opening 19 in the cuff 2 intended; this is offset to the side. Through this insertion opening 19 is the Eccentric introduced; then the eccentric (see Fig. 2) is shifted to the right, so that the pivot pin 5 can be pushed into its associated partial bore. An adjuster 4 is provided on the pivot 5 opposite the eccentric 3. This adjuster 4 can be designed as a handle (e.g. a simple toggle, a knurled wheel, etc.). The shell 1 wgst an increase, so that an abutment 7 is formed. Against this abutment lies one of the surfaces 15 to 18 of the Eccentric; the eccentric itself finds its abutment on the surface 6 via the pivot 5. Depending on the distance between the pivot 5 and the abutment 7, the sleeve 2 is more or inclined less forward.

Instead of the four areas shown here, of course, more or fewer areas are provided in a corresponding arrangement.

It is also part of the invention that the contact surfaces 15 to 18 of the Eccentric, which lie against the abutment, somewhat rounded, for example, of the same shape could be; then e.g. the abutment 7 would have a concave * curvature there, where the eccentric 3 is applied.

Reinforcements can be provided where the rotation occurs or washers to achieve stiffening; this is for example favorable in the area of the cuff 2.

This embodiment can have a certain disadvantage if the cuff 2 is relatively weak. The power transmission from the contact surface the abutment 6 to the abutment 7 then does not run linearly, but somewhat diagonally; with very high forces it could be * or convex thereby tilting of the eccentric 3 are caused.

This is countered by the embodiment according to FIGS. 3 and 4. Here are the force-transmitting surfaces 6/7 directly opposite each other. The eccentric 20 is here in principle similar to that according to FIG. 1, but designed differently. He has parallel opposing surfaces 13, 13a; 12, 12a and 11, 11a. The surfaces 13, 13a have the same distance from a fictitious center; this applies mutatis mutandis to surfaces 12, 12a and 11, 11a. If the eccentric 20 takes the a position shown in Fig. 4, then this is from the center of the eccentric the greatest distance. The forward incline of the cuff is greatest. A The surfaces 12, 12a bring a smaller distance if they are at the abutment 6 or 7 are present. The abutment 6 of the cuff 2 and the abutment 7 is the Assigned to shell 1.

The two opposite each other bring the smallest distance Areas 11, Ila, In this example, an elongated hole 8 is provided in the shell 1; the rotation in the direction of arrow 10 (can be done on both sides) is done by the pivot 5.

It is also part of the invention that one still has the surfaces of the eccentric Assigns cams or indentations. On the opposite surface 6, 7 then depressions would be and cams provided so that a kind of snap-in takes place. However, this is not necessary with the arrangement selected here. This would be then useful if you would make the eccentric round or oval, because they each other assigned surfaces could then twist too easily.

The eccentric 20 is introduced via a gap 14, for example. This can - when the shell 1 is still stretched - pull apart so far that that the pivot 5 can be introduced. In the same way, you could also have a Make a transverse elongated hole - e.g. provided in Fig. 4 above the elongated hole 8, in order to be able to spend the pivot 5 in the elongated hole 8.

So that the eccentric 20 can rotate, the sleeve 2 is a appropriate recess provided.

The retaining disk 9 prevents the eccentric 20 from slipping out. Here, too, reinforcements or washers can be provided, or wear and tear Apply inhibiting agents.

This eccentric should also preferably be made in one piece. In the case of multi-part production, the individual parts can be screwed together using a press fit be held together, welded or joined together by gluing.

It is not mandatory that the surfaces 13, 13a; 12, 12a and 11, 11a must be equidistant from the fictitious center. The distance from the parallel surfaces to this fictitious center point can also be different because the compensation is given by the elongated hole. However, they should each other opposing surfaces run as parallel as possible to one another. Needs the surfaces are not flat; these can also be convex or concave be arched.

It should also be noted that the elongated hole 8 is also in the cuff can be provided.
