    专利说明:

    The invention relates to a ski boot, in particular alpine or ski touring boot, with an inner boot of a flexible shaft material and a shell surrounding the inner shoe at least partially, the lower shell part at least partially enclosing the foot in the position of use, the one in an instep area substantially extending in the direction of a longitudinal axis of the shoe extendable manhole, and having an articulated to the lower shell part upper shell part, wherein in the instep area a rope-shaped traction means is provided, which is guided by means of deflection at least partially crossing the manhole, and the traction means Clamping element is assigned to initiate a clamping force.
    From the prior art, a variety of different shell ski boots is known in which a comparatively flexible liner in a shell consisting of a comparatively hard plastic material is added.
    In most cases, in conventional alpine ski boots, the lower shell part is substantially divided along the longitudinal axis of the shoe in the instep area, wherein in the instep area, lateral and medial portions of the lower shell part are overlapped and define a manhole. Usually, buckles are provided both in the instep area and in an upper shell part which encloses the user's tibia and shin, which allow the space enclosed by the shell to be changed to enable the user to customize the ski boot.
    From EP 2 881 004 Al, a ski boot, in particular touring ski boot, of the type mentioned at the outset is already known, in which the lower shell part is recessed in an instep area to form an entry opening. In this instep area, a pull rope is provided for tightening the shoe, which can be tightened by means of a closure element, in particular in the form of a rotary closure.
    In this touring ski boot, the pull rope is over long distances on the manhole, which is defined by the recessed area in the shell out, and the pull rope is crossed in this area, so that this disadvantageously the user uncomfortable pressure points in this open area of the shell may occur. In order to prevent entry of snow or water through the manhole into the interior of the shell, the recessed area of the shell is completely covered by a protective tongue.
    From DE 10 2013 112 017 Al a ski boot is further known, in which in the instep area a meandering traction cable is provided whose tensioning force can be adjusted by means of a fastening means and an adjustable deflection point.
    The aim of the present invention is therefore to provide a ski boot of the type mentioned, in which an individual, infinitely variable adaptation of the lower shell or of the shell trapped volume is possible, while ensuring that the shell under the Clamping force in the instep area adapts well to the user's foot without compromising on the user comfort.
    This is achieved by the features of the characterizing part of claim 1 according to the invention.
    With the aid of the section of the lower shell part provided in the instep area, which has a higher flexibility than the shell part in the section adjacent to the instep area, the cable-shaped traction element can thus be guided in a crossing manner in the instep area and due to the comparatively high flexibility of the shell part in FIG This section a particularly thorough and user-friendly adaptation of the lower shell part to the foot of the user can be achieved, but without having to guide the rope-shaped tension member over a comparatively large manhole, in which the lower shell part is recessed.
    The increase in the flexibility of the lower shell part in the region of the instep adjacent to the access opening can be achieved in a simple manner, in particular if a lateral and medial section of the lower shell part essentially each have a substantially extending in the direction of the longitudinal axis of the shoe edge to form the Entrance opening, wherein the lateral and / or medial section to increase the flexibility in the instep area essentially have transversely to the longitudinal axis of the shoe extending material recesses.
    Due to the material recesses running transversely or perpendicularly to the longitudinal axis of the shoe, tab-like projections, which-in comparison to a lateral and / or medial section with a continuous, straight edge-result in greater flexibility for adaptation to the individual foot of the user.
    If the edge of the lateral and / or medial section of the lower shell part delimiting the access opening has in each case an essentially wave-shaped course, wherein the material recesses form wave troughs, a harmonious transition thus results between those areas in which no material recesses are provided and such areas, which essentially remain in the instep area as a kind of wave crests and therefore have a relatively small distance from each other - under limitation of the access opening - and which are provided to increase the flexibility of the lower shell part in the instep area.
    In order to avoid as far as possible the installation of the rope-shaped traction device on the foot of the user, which could possibly lead to pressure points on the user, it is advantageous if the points of intersection of the traction device are substantially overlapping with those regions in which there are no material recesses.
    In order to achieve a different flexibility of the lower shell part adjacent to the manhole against a provided outside the instep area portion, different materials can be used in different portions of the lower shell part. Accordingly, it is advantageous if the lower shell part to increase the flexibility in
    The instep region comprises a portion of a material which has a lower rigidity, in particular flexural rigidity, than a material of the lower shell part in the region adjacent to the instep region.
    Basically, a two-component production is conceivable here. In terms of cost-effective production, however, it is advantageous if the portion of lower rigidity than the rest of the lower shell part separate part is formed and is connected to the other lower shell part.
    In order to achieve a reliable connection between the part of lower rigidity and the remaining lower shell part, it is advantageous if a connection between the part of lower rigidity and the remaining lower shell part via positive and / or non-positive connection elements, in particular pin-like connecting elements, preferably rivets or screws is provided.
    Conventional ski boots in particular have overlapping edges in the region of the manhole in order to prevent, among other things, an entry of snow or water into the interior of the outer shell. In order to reliably prevent snow entering the ski boot according to the invention with a manhole, it is therefore advantageous if the manhole is continuously covered with a flexible insert element.
    With regard to a structurally simple embodiment, it is advantageous in this case if the flexible insert element is connected in a liquid-tight manner to the section of higher flexibility defining the entry opening.
    In order to protect the entire foot of the user from the penetration of snow or water, it is particularly advantageous if the flexible insert element is designed as a sock-shaped element preferably surrounding a foot of the user up to over the ankle.
    In order to minimize frictional resistance in the intersecting guidance of the rope-shaped traction means in the instep area, it is favorable if at least partially, preferably exclusively, rotatably mounted rollers are provided as deflecting means. Due to the thus extremely low frictional resistance results for the user a particularly smooth way of tightening the rope-shaped traction device.
    With regard to a structurally simple storage of the rollers, it is advantageous if the rollers are each rotatably mounted on an axis of rotation, wherein the axis of rotation is preferably pivotally mounted. By the preferably pivotable mounting of the axes of rotation thus an optimal adjustment of the orientation of the rollers to the course of the rope-shaped traction means can be achieved and thus any frictional losses are further reduced.
    In order to enable individual adaptation of the individual deflection points to the foot, it is furthermore advantageous if the axes of rotation are respectively received in a bearing block having two holding fingers.
    If the bearing blocks in the higher flexibility portion of the lower shell part, preferably each via a pin-shaped connecting element, in particular a rivet or screw, are fixed, the bearings of the deflection can also better adapt to the individual foot shape of the user, so that the fit is further improved ,
    With regard to a high ease of use when tightening or applying a clamping force on the rope-shaped traction means, it is advantageous if a rotary or ratchet fastener is provided as a clamping element. Such screw caps are known in particular by the company Boa Technology Inc. for many years. Such closures are e.g. in US Pat. No. 5,934,599 A, US Pat. No. 6,202,953 B and numerous other applications of Boa Technology Inc. are described in detail.
    By contrast, ratchet fasteners are, for example, from the company AM Teknostampi S.p.A or Gl.DI. Meccanica S.p.A known.
    With regard to a high ease of use, it is also advantageous if the clamping element is arranged laterally in an upper end portion of the instep area on the lower shell part. Of course, however, the clamping element can also be arranged at a different position on the lower shell part, for example in the middle in the upper instep area or also in the transition area between the toe and instep area, etc.
    In order to distribute the tension forces introduced by the traction means as evenly as possible over the portion of higher flexibility, it is further advantageous if the tensioning element is fastened in the portion of higher rigidity of the lower shell part.
    With regard to an individual adaptation to the tibia or calf of the user, it is favorable if the upper shell part has at least one buckle.
    The invention will be explained in more detail below with reference to a preferred embodiment shown in the drawings, wherein it should in no way be limited thereto. In detail in the drawings:
    Fig. 1 is a perspective view of the ski boot according to the invention;
    Fig. 2 is a plan view of the ski boot according to the invention;
    3 shows a detailed view of the instep area of the lower shell part;
    Figure 4 is a rear view with a pivoted joint lock.
    5 shows a side view with a joint lock located in the blocking division;
    Fig. 6 is a detail view of the upper buckle of the upper shell part;
    7 shows a view of a lower shell part with reduced wall thickness in a section adjacent to the access opening; and
    8 shows a view of an insert part to be provided in the region of the access opening.
    FIG. 1 shows a ski boot 1, in particular a touring ski boot, with a lower shell part 2 and an upper shell part 3 articulated via a joint 3 'to the lower shell part 2.
    In the shell composed of the two shell parts 2 and 3, a comparatively made of a flexible material inner boot 4 is added, as is basically known from so-called. Cup ski boots ago.
    To improve the wearing comfort, in particular the possibility of individual adaptation to the foot of the user by means of reduction of an access opening provided in the instep area 5, a rope-shaped traction means 6 is guided crossing with the aid of rollers 7 in the instep area.
    The access opening 5 is in this case defined by a separate part 8, which is connected via a rivet connection 8 'with the rest of the lower shell part 2. This insertion opening 8 bounding the entry opening 5 is preferably made of a material which has a lower rigidity or a higher flexibility than the material outside the instep area. For example, the inserted part 8 may be made of a thermoplastic elastomer, e.g. a bending modulus of elasticity of 100-250 MPa, in particular 150 MPa or the like, whereas the lower remaining shell part 2 may be made of a polyamide 12 elastomer with a bending modulus between 600 and 1000 MPa, in particular 800 MPa or the like. Of course, the insert part 8 and the lower shell part 2 can also consist of only one material or both components consist of materials of the same chemical material group, provided that the rigidity is different.
    Production in a two-component injection molding process is also possible.
    In addition, increased flexibility in the instep area is achieved by the substantially wave-shaped course of the edge 5 'of the insert part 8 bounding the access opening 5 on both sides of a longitudinal axis L (see FIG. Here, the respective basically linear, parallel to the longitudinal axis L of the ski boot extending edge 9, transverse to the longitudinal axis L (see Fig. 2) extending material recesses 10 (see Fig. 3), so that a wave or meandering course of the edge 5 'results.
    By this transverse to the longitudinal axis L extending material recesses 10 resulting in the direction of the manhole 5 projecting tabs 10 ', which have a higher flexibility over conventional designs, in which the lateral and / or medial portion of the ski boot 1 have a straight edge.
    As can be seen further in FIG. 1, wave crests or flaps 10 'projecting in the direction of the access opening 5 and wave troughs in the area of the material recesses 10' are thus arranged such that these intersecting points 6 'are essentially overlapping with the wave crests or lugs 10 'are arranged so that in the region of the intersection points 6' in the closed state, in which the wave crests 10 'are largely approximated to each other, the crossing points 6' rest where possible in these areas and thus in these areas no direct contact with the foot of the user recorded in the ski boot 1 comes about.
    As further shown in Fig. 3, the rollers 7 are rotatably mounted on axes of rotation 7 ', which in turn are accommodated in bearing blocks 11. The bearing blocks 11 are in this case connected via rivets or screws 11 'with the material higher flexibility 8, so that when applying a clamping force on the traction cable 6 by means of a clamping element 12, the lower shell part 2, in particular including the bearing blocks or points 11, particularly intimately can adapt to the individual shape of the user's foot.
    As clamping element 12, as shown in FIGS. 1 and 3 in particular, a rotary closure is provided with which by turning a control element, the total length of the pull cable 6 can be shortened and thus a clamping force on the rollers 7 and the bearing blocks 11 on the lower shell part 2 can be applied, so that the distance between the lateral and medial portion of the shell part 2 to each other and the manhole 5 is reduced, and thus the foot of the user recorded in the shoe 1 is closely embraced.
    As can be seen further in FIG. 3, a flexible sock-shaped insert element 13 is connected to the insert part 8 in a liquid-tight manner, in particular via an adhesive connection. Thus, the manhole 5 is protected against ingress of snow or liquid via the inlet opening 5 in the direction of the liner 4. In this case, this insert element 13 can be guided high above the area of the ankle of the user, in particular in the manner of a sock, so that a penetration of liquid or snow to the foot of the user can be reliably prevented. The insert element 13 here consists of a liquid-tight material, in particular a liquid-tight textile fabric, e.g. of polyamide or polyester, or a soft elastic film, e.g. from a thermoplastic polyurethane elastomer or the like. Of particular advantage is that - if the insert element 13 is made of a textile - on this textile on the inside of a waterproof and breathable membrane is additionally attached, for. Goretex® from Gore. This measure not only ensures watertightness, but also achieves breathability.
    As further shown in Figs. 5 and 6, the touring ski boot 1 in a conventional manner on its rear side a pivotable locking lever 14. If this blocking lever 14, as shown in FIG. 4, is not in engagement with a bolt 15 which is provided in the heel region of the lower shell part 2, the upper shell part 3 is freely pivotable relative to the lower shell part 2 via the joint 3 '. This release position is particularly useful when climbing with touring skis.
    In order to achieve the most direct possible transmission of power from the ski boot 1 to the ski in the course of the descent, the locking lever 14 is in positive or non-positive engagement with the bolt 15, as shown in FIG. 5, so that the joint 3 'is located between the lower shell part 2 and upper shell part 3 is blocked in this locking division.
    In addition, it is still apparent in FIG. 6 that the circumference of the upper shell part 3, which is substantially cuff-shaped, can be fixed by means of a buckle 17.
    The buckle 17 in this case has a guide 17 ', in which a bolt 18 is slidably mounted. The bolt 18 in turn is connected to an upper closure band 19, which is passed through an eyelet 20 and deflected and then by means of a hook and loop fastener in different extent in the region of the upper shell part 2 can be determined. In the open position of the buckle 17, therefore, a comparatively large circumference of the shell part 3 is defined, but without giving it completely free. This position is particularly advantageous for the ascent, whereas for the downhill the buckle 18 is closed, so that the upper shell part 3 encloses the foot of the user closely in the region of the tibia and the calf.
    Fig. 7 shows a particularly simple and economically producible embodiment. In this case, the lower shell part 2 adjacent to the manhole 5 each have a wave or meandering edge course 5 'on. In addition, the adjacent to the manhole 5 section 22 has a smaller wall thickness than the rest of the lower shell part 2. An edge 22 ', which defines the transition to the rest of the shell part of greater wall thickness, here is also wave or meander-shaped. With the help of both measures, the flexibility of the section adjoining the access opening 5 relative to the remaining lower shell part 2 is increased (independently of one another).
    In the recess 22 formed by the portion of lesser wall thickness, an insert part 8 with a wavy or meandering outer edge profile 23 corresponding to the edge 22 'can be used. The insert 8 may in this embodiment have a kind of frame 24, which is made of a relatively elastic plastic. This frame 24 is sprayed onto a sealing tab 25, in particular a textile, by injection molding.
    As can be seen in FIG. 7, in the section 22 of lesser wall thickness, the part 8, as shown in FIG. 8, can be glued onto the shell 2 using an adequate adhesive. The inserted part 8 also has recesses 27, which serve in particular as orientation or guidance points to make recognizable, where in a further step, the bearing blocks 11 can be riveted or screwed to the pulleys 7 on the shell 2.
    As can also be seen in FIG. 8, the sealing tab 25 can also be provided with a central web 28, which is preferably also applied to the sealing tab 25 by injection molding. The central web 28 therefore has similar or the same flexibility as the frame 24, but the central web 28 and frame 24 are less flexible with respect to the cover flap 25, so that the inserted part 8 automatically folds in the assembled state when closing the shoe like a water strap of a mountaineering shoe ,
    In the embodiment according to FIGS. 7 and 8, the number of parts can accordingly be reduced and a particularly simple assembly can take place.
