Abstract

The invention concerns a ski boot having a shell (1), a movable toe cap (2) and a leg (3). In the pivot region of the toe cap (2), the ski boot has a recess (5) which is closed by a covering (6) of the toe cap (2). The covering (6) engages below the instep area of the shell (1) and, viewed along the longitudinal section of the ski boot, is curved spherically with a radius corresponding to the distance from the imaginary pivot axis of the toe cap (2). At the free edge of the covering (6), and also of the recess (5) on the instep side, strips (7, 8) facing one another are each provided with hook-shaped undercuts which engage one another in an interlocking manner in the extended position of the sole (4) or toe cap (2). Associated with a tongue (9) of the covering (6) in the longitudinal centre of the ski boot is a locking device (10, 10') which is guided transversely to the covering and which, as a variable stop, permits, restricts or prevents play in the movement of the toe cap (2). The locking device (10, 10') is displaced by a Bowden cable (14) against the force of a spring (15). An actuating lever (17, 22, 22') is provided which additionally secures the leg (3) with respect to the shell (1) in the forward lean position. The toe cap (2) is advantageously locked by the effect of tension on the Bowden cable (14) which is released on unlocking with respect to the actuating lever (17, 22, 22').

Description

Ski boot

TECHNICAL AREA

The invention relates to a ski boot with a shell with sole and toe cap holding the foot at least in the instep area and a shaft surrounding the leg, the shell and toe cap being made in one piece from plastic and pivotably connected to one another by the sole, a toe cap adjoining the toe cap. the ski shoe is provided with a recess that extends essentially over its entire width in the shell, which delimits the pivoting range of the toe cap, and adjoins the toe cap with a cover protruding over the edge of the cap, which engages under the recess and when the toe cap is pivoted under the instep area of the toe cap Shell is slidable.

On the one hand, a ski boot should form an essentially rigid unit in connection with the ski, the toe cap being held in the extended position and the shaft in a template position, on the other hand, the sole should be able to roll off when walking. To do this, use a toe cap that can be swiveled in relation to the shell. In the case of a one-piece construction of the shell of the ski boot made of plastic, the articulated connection with the toe cap takes place via the sole, which can be curved in the pivoting area by a transverse groove.

BASIC PRIOR ART

A sports shoe is known from PCT WO 92/19117 which comprises a pivotable toe cap which is articulated to the shell at a distance in the form of a gap-like recess over the sole of the shell for the purpose of relative mobility to the shell. This recess is bridged on both sides by a cover that slides under the shell when walking. The essential, middle part of the recess is covered by a deformable insert. This is compressed when the toe cap is swiveled in and expands Reaching the stretched position. The deformable material, such as foam rubber, is subjected to very high stresses due to cold, moisture and constant changes in shape, so that cracks and, subsequently, sealing problems can result, in particular at the connection points to the toe cap on the one hand and to the shell on the other. An actuator in the shell blocks the toe cap when skiing. This blocking can take place via a linkage by means of a heel-side pusher which is inserted by a binding element, such as the automatic heel unit.

A ski boot is also known from AT-PS 356 541, which is formed in one piece and has an inner stiffening insert. The stiffening insert is arranged in the sole area and consists of two parts that are connected to each other by a hinge. This ski boot has an elasticity in the toe area that depends on the specific structure. An individual toe cap can only be found in the stiffening insert.

DE-A1-24 44 064 describes a forefoot heel cup for ski boots, in which a partial cup receiving the toe-ball area can be pivoted and locked with respect to the rest of the cup about a transverse axis located on or near the sole, the mutually facing ones , subdivision edges of the partial shell and the remaining shell located outside the sole overlap one another. At least in a region of the free end edge of the cover which engages under the shell and the edge of the shell which delimits the recess, strips which are directed towards one another are provided. Finally, from AT-B-379 731 a ski boot is known which has a lower part holding the foot and an upper holding the leg and designed as a shaft, which parts are connected to one another by a bellows, the stiffness of the bellows being in the region from the front of which can be changed by inserting a stiffening element between the folds of the bellows. The stiffening element is designed in the manner of a toothed strip, the teeth of which in the extended position of the bellows engage between the folds, which are preferably provided with a trapezoidal cross section.

DISCLOSURE OF THE INVENTION

The invention aims to improve the seal relative to the shell in a ski boot with a movable toe cap. This is achieved in the case of a ski boot of the type mentioned at the outset in that the cover, seen in the longitudinal section of the ski boot, is curved and has a curvature which decreases from the longitudinal center plane in parallel planes towards both sides with increasing distance, the radius of curvature preferably corresponds approximately at a distance from the cover to the pivot axis of the sole, in particular for the imaginary connection of the ends of the recess on the sole side. The cover not only continues the toe cap below the gap in the recess, which forms the space for pivoting, but is curved in the manner of a ball joint in addition to the arch shape. The surface is similar to a strip of an ellipsoid. With each movement, the surfaces lie close together. The radius of the curvature decreases with the distance from the longitudinal center plane of the ski boot. The radius of curvature disappears entirely on the side parts. It is particularly expedient if, at least in a region of the free end edge of the cover which engages under the shell and the edge of the shell which delimits the recess, mutually opposed strips with undercuts are provided which interlock positively in the extended position of the sole. The stretch of the sole is the one that occurs when skiing. In this important position, the strips engage in a claw-like manner. If the undercuts are U-shaped and the complementary strips have the same projections, then wedge surfaces run against one another and self-centering takes place. Furthermore, a very good seal can be achieved in the stretched position. The interlocking elements also have the effect that the sole cannot be stretched beyond the horizontal plane. This results in an end stop with the largest permissible recess or gap width. The shell and toe cap are rigidly coupled to one another in the stretched position by the positive connection of the interlocking undercuts. In a special embodiment it is provided that on the toe cap, in particular in the longitudinal center thereof, a rotatable locking bar is provided which overlaps the recess for fixing the toe cap in the extended position of the sole and is supported with an end face on the shell and for Release of the pivotability of the toe cap can be rotated out of the area of the recess. The rotary latch can have the shape of an eccentric, which is rotatably mounted on the shell or cap side and overlaps the recess for fixing the position of the cap in the extended position. A constant thickness is particularly well suited for this purpose. A concealed and protected construction for toe cap fixing or release, which is not visible from the outside, is characterized in that on the cover, in particular on a tongue protruding from the cover in the longitudinal center of the ski boot, a contact surface and a control surface of this in opposite The bar is provided for the bar guided to the longitudinal axis of the ski boot, that the control surface preferably has two sections in the sliding direction of the bar, which are stepped with respect to one another and merge into one another by a slope, one section of which toes cap when running onto the contact surface locked in the position of its extended position and the other section is set back to the extent of the freedom of movement of the toe cap. Depending on the latch position, there is a degree of freedom of the toe cap, limited availability or prevented. The bolt can be displaced against spring force via a handle, but advantageously also by means of a Bowden cable, which is guided in the heel region of the shell to an actuating lever, the latter preferably also a spring-loaded locking pin for locking the shell and shaft controls. The toe cap fixation in the stretched position is useful when skiing. At the same time, however, is the template position by fixing the sheep tes in the inclined position with respect to the shell for the departure. This can be achieved with the one operating lever that controls the Bowden cable and the spring-loaded self-engaging pin. A practical addition results from the fact that the rotary latch or latch carries position identifications, for example the colors red and green, on its top side, one of which, depending on the position of the rotary latch or latch, is opposite a viewing window in the instep area of the shell. A practical design is characterized in that an approximately U-shaped bracket is connected to the actuating lever, which laterally encompasses and engages under a covering tongue and into which the Bowden cable is suspended below the covering tongue, the cable of which is deflected in a base plate is guided, on which the jacket hose of the Bowden cable is supported. It is expedient if the section of the latch which fixes the toe cap in the extended position is designed as an inclined surface which, when it strikes the contact surface of the toe cap, for example by the force of the spring, transmits a pretension to the toe cap, the hook-shaped undercuts of the strips lie against one another under pressure. In order to ensure the locking by lever force via the Bowden cable, it is provided that the Bowden cable is connected or hooked in at that end of the bolt which is the portion which is set back to unlock the toe cap, the bolt with its bevels and with the adjoining one Section on tension on the part of the Bowden cable runs onto the contact surface of the toe cap and presses the toe cap into the extended position. The Bowden cable can, however, also be connected or hooked to that end of the bolt which is removed from the section set back to unlock the toe cap, the bolt with its bevels and with the adjoining section when the Bowden cable is relaxed under the action of a relaxing spring runs onto the contact surface of the toe cap and locks the toe cap in the extended position.

BEST EMBODIMENT OF THE INVENTION

1 to 5, a ski boot comprises a shell 1 with a pivotably articulated toe cap 2 and with a shaft 3 which can also be pivoted (FIG. 2). A sole 4 is part of the shell 1 and merges into the toe cap 2. 1, the shell 1, sole 4 and toe cap 2 are molded in one piece from plastic. A recess 5 is provided between the toe cap 2 and the shell 1, which allows the toe cap 2 to pivot. Fig. 2 shows the formation of the recess in view. The sole 4 can have a groove in the area of the imaginary connection between the ends of the recess 5, which groove represents a defined axis of rotation for the toe cap 2. In many cases, the elasticity of the plastic is sufficient for the sole 4 to bend, even without special design measures. A cover 6 adjoins the toe cap 2, which engages under the recess 5 and is pushed under the instep area of the shell 1 when the toe cap 2 is pivoted, for example when walking. In order to achieve a good seal, the outer surface of the cover 6 is curved. in the Longitudinal section according to FIG. 1 results in a circular arc on the surface of the cover 6 with a radius which corresponds to the distance to the (imaginary) axis of rotation of the toe cap 2. At the free edges of the cover 6 and the recess 5, opposing strips 7, 8 are provided. These have hook-like undercuts with inclined surfaces (wedge surfaces) that run together, so that there is a positive, tight connection in the extended position of the sole 4 (FIG. 1). According to FIG. 1a, the spherically curved surface of the cover 6 slides under the instep area of the shell 1 when the toe cap 2 is bent - adjoining the ledge 8. The contact surface of the ledge 8 can be adjusted to the curvature of the surface of the cover 6 be matched. Dirt, in particular snow, is pushed out of the recess 5 when walking through the inclined end faces in the transition area of the toe cap 2 to the cover 6 and on the end face of the last 8. The strips 7, 8 with their interlocking connections end in the transition area between the shell upper part and the shell side surfaces, but they can also be pulled down to the end of the recess 5. The toe cap 2 should be movable when walking, but the ski boot should hold the foot largely rigidly when skiing. According to FIGS. 2 and 2a, the toe cap 2 has a tongue 9 which projects from the cover 5 and which is guided under the instep area of the shell 1, optionally into a channel of the shell 1, in order to fix it in the extended position of the sole. This tongue 9 follows the movements of the toe cap 2 as a largely linear movement. A contact surface is formed on the tongue 9 on its end face. Transverse to the direction of movement of the tongue 9, a bolt 10 is guided in the shell 1 or in a bolt housing which is arranged in a fixed manner in the shell 1. The latch 10 laterally carries two stepped control surfaces 11, 12 which merge into one another by a bevel 13. If the latch 10 is positioned as shown in FIGS. 2 and 2a, then the control surface 11 lies directly against the contact surface of the tongue 9 and prevents any movement of the toe cap 2. However, if the latch 10 is displaced, such as shown in dashed lines in FIG. sets - the set-back control surface 12 of the bolt 10 is at a distance from the contact surface of the tongue 9, then the toe cap 2 can be pivoted until the set-back latch stop comes into effect. The latch 9 can also be designed such that it only has the inclined surface 13 and the control surface 11, so that the tongue 9 is either blocked by the latch 10 or the free space is available when the latch 10 is retracted. The inclined surface 13 of the latch 10 serves to bring the toe cap 2 into the extended position of the sole 4 during the locking process.

2 shows the displacement of the bolt 10 by a Bowden cable 14. The bolt 10 is pressed by a spring 15 into the illustrated locking position of the toe cap 2 and can be withdrawn against the action of the spring 15. For this purpose, the Bowden cable 14 is suspended in a bracket 16 of a pivotable actuating lever 17. If train is exerted on the Bowden cable 14 by the actuating lever 17, the bolt 10 moves into its release position. The return takes care of the spring 15 as soon as the pulling effect ceases to exist. A cover tongue 19 is attached below the actuating lever 17 on the same axis 18. When the operating lever 17 is pivoted up, this protects and covers the hooking point of the Bowden cable 14 into the bracket 16. Finally, the actuating lever 17 also brings a locking pin 20 into and out of engagement with the shell 1 or shaft 3. If the actuating lever 17 is mounted on the shell 1, then the locking pin 20 engages in a bore in the shaft 3, so that its position (template position for skiing) can be fixed. When the actuating lever 17 is mounted on the shaft 3, the locking pin 20 engages in a bore in the shell 1. In each case, shell 1 and shaft 3 are locked. This locking of the shaft 3 in the original position goes hand in hand with the locking of the toe cap 2 in the extended position of the sole 4. FIGS. 3 and 3a show the ten-cap locking according to

2 and 2a in section. In Fig. 3, the tongue 9 is on the surface 11 of the bolt 10 and can not move. Overstretching is not possible because the hook-like rear intersections of strips 7, 8 interlock. If the control surface 11 is designed as an inclined surface 11 ", it exerts pressure on the tongue 9 under the action of the spring 15, so that the hook-like undercut strips 7, 8 engage in one another under tension. This supports the sealing effect of the cover 5 compared to the shell 1 in the area of the strips 7, 8, to which very high demands are made, especially when skiing, for example in powder snow. In Fig. 3a, the control surface 12 faces the tongue 9 and forms a stop at the end of the Swiveling range of the toe cap 2. Above the latch 10 there is a viewing window 21 in the shell 1, through which the respective latch position can be seen. The top of the latch 10 can be green in the area of the control surface 11 or 11 "(for skiing) and colored red in the area of the control surface 12 (for walking).

3 shows the Bowden cable 14 again, but it works together with a somewhat differently designed actuating lever 22. The latter is mounted rotatably about an axis of rotation 23 on the shaft 3 or on the shell 1. A U-shaped bracket 24 is articulated on the actuating lever 22, on which the Bowden cable 14 attaches. The pivoted-up position of the actuating lever 22 causes a tensile force on the bolt 10, which reaches the position according to FIG. 3 against spring force. The pivoted-off, broken line position of the actuating lever 22 allows the spring of the bolt 10 to take effect, so that the situation according to FIG. 3a results.

The actuating lever 22 is designed in the region of the axis of rotation as an eccentric and presses a spring-loaded locking pin 25 against the ski boot. The locking pin 25 snaps into the bore 26 of the shell 1 as soon as the bore 26 is aligned with the locking pin axis. This is the case in the original position of the shaft 3 in relation to the shell 1. 1 also shows a rotary latch 30 on the toe cap 2, which can be rotated into the recess about an axis of rotation 30 'and which has its end face on the shell 1 in the area of the strip 8 for fixing the position can support the toe cap 2. These particularly easy The design is expedient if only the toe cap 2 is to be released and fixed, but an actuating lever for fixing the shaft is not present.

4 and 4a and 5 and 5a are similar to FIGS. 2, 2a and 3, 3a, with the Bowden cable 14 as an alternative releasing the latch 10 'when the actuating lever 22' is turned down from the position shown in FIG. 4, pulls into the locked position of the toe cap 2. 2, 2a, the toe cap 2 was unlocked by the tensile action of the Bowden cable 14 and the locking was brought about essentially by the force of the spring 15. According to FIG. 4, the latch 10 ', which is displaceably guided transversely to the tongue 9 of the toe cap 2, has two sections 11' and 12 'which merge into one another by a bevel 13'. The section 11 'protrudes from the section 12' and holds the toe cap 2 in the rigid extended position by resting or pressing it against the end face of the tongue 9. 4 and 4a show the unlocking position, in which the latch 10 'with its section 12' lies opposite the tongue 9 and frees the toe cap 2 to move. 4a shows the bolt 10 'in relation to the tongue 9 in detail.

By moving the operating lever 22 'downward from the position shown in full lines in FIG. 4, a tensile force transmitted through the bracket 24' is exerted on the Bowden cable 14, so that the bolt 10 'against the force of the springs 15 4 or 4a is pulled to the right. As a result, the section 11 'slides in front of the tongue 9. When the toe cap 2 was bent upwards, the slope 13' runs onto the tongue 9 and presses the toe cap 2 into the stretched position shown in FIG. 4. The connection between the Bowden cable 14 and the bracket 24 'of the actuating lever 22' takes place via a hook 31 at the end of the Bowden cable, the free leg 31 'of which is longer than its displacement path when the actuating lever 22' is changed over. This results in an exemption between the actuating lever 22 'and the Bowden cable 14 and it is possible to pivot the actuating lever 22' up from the locked position into the release order of the toe cap movement, even if the spring 15 provides the frictional engagement between the belt gel segment 11 'and the end face of the tongue 9 can at best not overcome at the moment. By stretching the toe cap 2, the tongue 9 lifts off the section 11 ', as a result of which the bolt 10' snaps into the release position according to FIG. The bracket 24 'always remains within the hook 30. A threading out of the hook 30 is counteracted by the long leg 31. The U-shaped recess in the cover tongue 19 serves to guide the hook 30. The release position is shown here between the Bowden cable 14 and the actuating lever 22 '- but it can also be provided between the Bowden cable 14 and the bolt 10' in such a way that the bolt-side end of the Bowden cable 14 is not fixedly connected to the bolt 10 ', but when the actuating lever 22 is switched to its release position, a head end of the Bowden cable 14 lifts off a bolt-side driving surface and withdraws when the spring force 15 briefly or temporarily with respect to the frictional resistance the locking should not be sufficient to push the latch 10 'into the released position of the toe cap movement.

The bolt 10 ', which is guided inside the shell 1, is opposite a window 21, which can be identified by color markings on the bolt 10'.

4a, the locking device, as described above, is shown again in detail in a flat position. The solid bar 10 'shows the release position of the toe cap 2, in which the tongue 9 has a range of movement in the direction of the arrow up to the stop on the section 12'. If the Bowden cable 14 is pulled through the actuating lever 22 ', the bolt 10' moves to the right in FIG. 4a and the bevel 13 'presses the toe cap 2 into the extended position. Section 11 'fixes this position. If the section 11 'has an inclined surface 11 ", then the toe cap 2 is also pressed forward when locking and the undercuts of the lasts 7, 8 are pressed against one another, for example in the elastic area. The actuating lever 22' is in addition to exerting the pull the Bowden cable 14 still the function of locking the shaft 3 and shell 1 of the ski schuhes, at the same time with the position of the toe cap 2 in the stretched position. The actuating lever 22 'has an eccentric 32 about its axis of rotation 23', which controls a spring-loaded locking pin 33. 4, the eccentric 32 is positioned such that the locking pin 33 withdraws from a bore 34 in the shell 1. If the actuating lever 22 'is turned down, the eccentric 32 presses the locking pin 33 into the bore 34, as shown in FIG. 5. Shell 3 and shaft 1 are rigidly connected.

5 and 5a show the exemplary embodiment according to FIGS. 4, 4a in section, the FIG. 5, in contrast to FIG. 4, as mentioned, representing the locked state of the toe cap 2, while the detail according to FIG. 5a shows the release position , in which the toe cap 2 can be pivoted until the tongue 9 bears on the section 12 '. 5 shows that the bracket 24 'in the swiveled-up position of the actuating lever 22' with the Bowden cable 14 relieved is still inside the hook 31 when the hook 31 is at the other end of the Bowden cable 14 by the spring 15 does not follow the movement of the bracket 24 '.

It should also be mentioned that the locking pin 33 in its guide in the shaft 3 follows the eccentric 32 in its axial direction, but that a spring element is interposed so that the locking pin 33 is pretensioned against the shell 1 by spring force in the actuating lever position according to FIG. 5 and engages in the bore 34 as soon as it is aligned with the locking pin 33.
