Description

Ski boot

The invention relates to a ski boot according to the preamble of claim 1.

Ski boots with rear entry are increasing common. A known version (DE-OS 29 07 163 and DE-OS 33 42 121) has a from the shell main body to the rear swiveling spoiler and an inner shoe that is in the instep is completely closed and its up

IQ to the heel continuously open rear area has a heel tongue. In this embodiment, the heel is inadequately held in the inner shoe, which cannot be compensated for by pressure exerted on the forefoot (instep area) by means of additional tensioning devices.

It is also unfavorable in this known ski boot with rear entry that the in the Instep part made from one piece, neither when entering the ski boot from behind, still has sufficient flexibility when in use. This is what happens again and again in practice determine that an ideally fitting inner shoe when buying it in the store when using it

but there is pressure in the instep area, since the foot generally swells a little during sporting activity, but the inner shoe hardly yields in the instep area.
30th

In another ski boot with rear entry known from practice, the inner boot is divided into two or three parts, with one or two parts attached to the shell of the ski boot, in particular are attached to the pivotable spoiler. This division of the inner shoe results however, especially in the heel area, an overlap of several shoe parts, which is a risk of pressure points in this sensitive FuS region.

The preamble of the claim represents a significant improvement over these statements 1 corresponding ski boot known from the applicant's company brochure "ZENIT SM" represents, in which the designed as drawstrings, cooperate with the central lock Tension elements of DE-PS 22 31 211 correspond.

In this known ski boot, the shell tongue is at an angle of about 90 ° with respect to the Shell main body can be swiveled away. When putting on the ski boot, the drawstrings must be in Engagement with the central lock can be brought.

the; in a corresponding manner, when the ski boot is taken off, the drawstrings are released from the central lock necessary before swiveling up the shell tongue.

The invention is based on the object of the ski boot according to the preamble of claim 1 there to develop that - under warranty

8th'

a comfortable rear entry and a pressure-free, firm fit of the heel in the inner shoe as well as an expansion option for the foot, especially in the instep area - practical handling the ski boot is further facilitated when putting on and taking off.

This object is achieved according to the invention by the characterizing Features of claim 1 solved.

The fixed connection of the tension elements with the shell tongue eliminates the need for the one according to the invention Ski boot the need to hang the tension elements in the central lock when putting on of the ski boot and a release of the tension elements from the central lock when taking off the Ski boots.

Since the shell tongue can only be pivoted through a limited angle with respect to the shell main body is, there is no risk that the tongue or the instep part of the inner shoe when it is wide open Shell tongue gets into the front slot of the shell main body and when you close the again The shell tongue becomes trapped in this slot, causing permanent damage to the liner and create undesirable pressure on the foot.

On the other hand, the limited pivoting mobility of the shell tongue is dimensioned in such a way that

The ski boot shown in Fig. 1 consists essentially of a shell 1 made of rigid Plastic and an inner shoe 2 made of elastically deformable material.

The shell 1 includes a shell main body 3, one in the front region of the shell main body pivotably articulated shell tongue 4 and one pivotable in the heel area of the shell main body 3 hinged spoiler 5.

The shell tongue 4 carries in its central area a central lock 6, which with two for Heel area of the shell main body 3 out pulling elements interacts, which is based on the Fig. 2 to 4 will be explained in detail. In the upper area of the shell tongue 4 and spoiler 5 a shaft lock 7 is also provided, from

which in Fig. 1 only the tab can be seen.

The spoiler 5 is mounted on the shell main body 3 such that it can pivot via two pivot joint axles 8, 9. These swivel joint axes 8 and 9 also form the deflection points for the element or elements, which connect the central lock 6 to the heel area of the shell main body 3.

With the in'Fig. The embodiment shown in FIG. 2 is a single pulling element made of steel wire formed pull rope 10 is provided, which from the central lock 6 (not illustrated in Fig. 2) through a first opening 11 in the shell main body to a steering axis 9 formed by the Schvvenkge first deflection point in the shell main body is guided on the one (left) side of the heel area, from here through the opening mentioned 11 over the instep part of the shell main body 3, which is divided by a slot 12, and a second opening 13 in the shell main body to a second deflection point formed by the pivot joint axis 8 is guided in the shell main body on the other (right) side of the heel area and that of from this through the second opening 13 runs back to the central lock 6. The two ends of the Pull cables 10 are firmly connected to the central lock 6.

Fig. 1 shows the ski boot in full lines

in the open state of the central lock 6 and the central lock 7. The spoiler 5 can thereby If desired, swivel it further backwards. Likewise, the inner shoe 2 can largely open, which is explained in detail with reference to FIGS. The shell tongue 4 is open Central lock 6 can be pivoted upward through a limited angle with respect to the shell main body 3 (This pivoting movement allows the shell tongue 4 in the area of the central lock 6, for example be raised by a measure of 2 to 6 cm. In this position, the user can be comfortable get into the ski boot from behind, which is then secured by means of the shaft lock 7 and the central lock 6 is closed. The shaft width can be determined by means of the shaft fastener 7 and adjust the heel width by means of the central lock 6 independently of one another.

If the central lock 6 is closed and the pull rope 10 is tightened as a result, it narrows Heel space, while at the same time a pressure adjustable in size via the shell main body 3 is exercised on the instep of the inner shoe 2. Since the slot 2 in the shell main body 3 somewhat narrowed when pulling the pull rope 10, the inner shoe 2 experiences in the area of the forefoot also a desired lateral support. The user's foot swells when exercising Actuation something, the user can by partially relaxing the central lock 6

Reduce the pressure exerted on the heel area and the instep and give the foot more leeway, after the shell main body 3 in the area of the slot 12 also opens more by partially relaxing the pulling part 10. With reference to FIGS. 7 and 8, it will be explained how the design of the inner shoe 2 ensures good adaptation of the inner shoe to different conditions.

In the embodiment of FIG. 3 is a single traction cable 10 'central shutter 6 (not shown) from the through a first opening 11' in the shell main body 3 'to a through the pivot axis 9' formed first deflection in the shell main body 3 ^J on the one (left) Side of the heel area. From here, the rope 10 runs ^a over the Ristpartie the inner shoe 2 to a from the pivot axis 8 '(right) second deflection point formed in the main shell body on the other side of the heel region and from here through a second opening 13' back to the central closure. In this exemplary embodiment, the pressure exerted by part of the tensioned pull rope 10 ^J acts directly on the inner shoe 2. Otherwise, the function corresponds to that of the exemplary embodiment already explained with reference to FIGS.

In the variant according to FIG. 4, a first pull rope 10a leads from the central lock through a first one

Opening 11 of the shell main body 3 to the pivot axis 9 and from here through the opening 11 back to the central lock. A second pull rope 10b runs from the central lock through the second opening 13 to the pivot axis 8 and from here through the opening 13 back to the Central lock. The function corresponds to the exemplary embodiment according to FIGS. 1 and 2.

In all three variants according to FIGS. 2, 3 and 4, those provided in the shell main body 3 or 3 'are provided Openings 11, 13 or 11 ', 13' through which the pull cords 10, 10 'or 10a, 10b are passed are covered by the shell tongue 4 to the outside.

FIGS. 5 and 6 illustrate the pivoting articulation of the shell tongue 4 on the shell main body 3. Since the shell tongue 4 is only at a limited angle (of for example 10 to 25 °) to be pivotable with respect to the shell main body 3, the pivot point 14 is simple Flexural joint formed. For this purpose, the shell tongue 4 is provided with a slot in the front area 4a, in which a flat projection 3a of the shell main body 3 engages. Another Projection 3b of the shell main body 3 supports the shell tongue 4 on the underside.

The one located between the projections 3a and 3b Part 4b of the shell tongue 4 is provided with an opening 4c into which a knob-like thickening 3c of the projection 3a engages.

In this way, a bending joint is created without the use of a hinge, the one limited pivoting movement of the shell tongue 4 relative to the shell main body.

The inner shoe 2 will now be explained in more detail with reference to FIGS. 7 and 8.

It contains a shaft 22 which is provided with two lateral slots 23 which extend from the upper edge of the Shank 22 go out and end at point 23a below the heel. The one on the side of those two Slits 23 delimited the middle and upper area 24a of the rear, which is continuous from top to bottom The shaft part 24 is opposite the lower region 24b of the rear shaft part which surrounds the heel 24 can be pivoted backwards, as indicated in FIG. 7 with dashed lines.

In order to facilitate this pivoting movement of the rear shaft part 24 with respect to the front shaft part 25, connects to the rounded lower end (point 23a) of the two side slots 23 each a flexibly designed gusset 26. In addition, the transition zone 27 is between the lower area 24b and the middle and upper area 24a of the rear shaft part 24 designed to be flexible. This transition zone 27 thus forms, so to speak, a pivot point around which the rear shaft part 24 can be swiveled backwards to get into the inner shoe.

The instep portion 28 of the inner shoe 2 is designed to be movable to a limited extent in the vertical direction. to For this purpose, at least one expansion zone 29 is provided in the area of the instep part 28, which starts from the shaft 22 and - following the shoe contour - in an arc up to the front area 30 of the shoe extends.

In the embodiment shown in FIG. 7, the instep portion 28 of the inner shoe is on both sides 2 each one expansion zone 29 is provided. It is carried out in the exemplary embodiment according to FIG a slot is formed which extends in the manner indicated by a dashed line 29a can open so that the instep 28 is illustrated by the dashed line 28a Shape can bulge upwards. As a result, on the one hand, the rear entry into the inner shoe 2 becomes essential relieved, and on the other hand, the instep 28 can be felt in the sporty Actuation to ideally adjust the swelling forefoot.

In the further embodiment shown in FIG. 8 in a cross section through the forefoot, the two expansion zones 29 ^! that laterally limit the instep section 28 ', designed as a bellows, the foam padding of the inner shoe being omitted in the area of this expansion zone 29' or the wall thickness reduced to such an extent that the expansion zones 29 'have good flexibility. When getting into the inner shoe as well as with

Swelling of the foot during use can deform the instep 28 'outward, as through the dashed line 28'a is indicated.

In contrast to the exemplary embodiments shown, only a single expansion zone 29 or 29 'can be provided, which is then expediently arranged in the longitudinal center of the instep portion 28 or 28'.
10

The expansion zone 29 or 29 'is expediently given a Arc length from 8 to 25 cm, preferably from 14 to 20 cm.

The distance between the two expansion zones 29 and 29 'is - over the circumference of the instep section 28 and 28' measured - expediently 5 to 16 cm, preferably 8 to 12 cm.

The two lateral slots 23 in the shaft 22 expediently end 6 to 14 cm, preferably 8 to 11 cm, above the sole of the inner shoe 2.

The inner shoe 2 shown in FIGS. 7 and 8 is particularly suitable for use in the ski boot 1 to 6, since the design of the rear shaft part 24 and the vertical In the direction of the movable instep section 28, on the one hand, facilitate rear entry into the ski boot and on the other hand via the central lock 6 and the pull cords 10, 10 'or 10a, 10b an ideal Adaptation of the instep of the inner shoe to the

Allow the user's foot (while ensuring a consistently good heel fit). It should be emphasized, however, that traditionally designed inner shoes (either with a tongue in the instep area or with a continuously shaped instep area) in the Ski boot according to the invention can be used.
