    专利说明:

    The invention relates to a ski, in particular a cross-country ski, with a tread layer, wherein the tread layer in a central region, in particular a riser zone, at least two groove-shaped recesses for attachment of a respective rebacking-inhibiting element.
    Skis with a plurality of grooves for receiving or attaching as climbing aid Rückgleithemmenden elements are already known in the art. If the climbing aids are releasably secured in the recess, this has the advantage that the user can optimize the type of Rückgleithemmenden elements as desired for his individual application. For example, if the user prefers to travel on groomed trails, he will e.g. Use a coated wax tape or sawtooth profile tape to optimize its progression. The user preferably moves in open terrain, the user in the groove preferably a coat or the like. Arrange.
    From DE 211 07 37 A, for example, a ski is known, in which the side of a centrally arranged groove two strip-shaped recesses in the tread layer are present, in which strip-shaped Rückgleithemmende elements can be used. The disadvantage here is in particular that at a load change from a sliding into a climbing phase, the two climbing aids used in the recesses abruptly unfold their re-hindering effect. Insofar as during the sliding phase by an unwanted body weight shift or lane unevenness therefore rewinding the elements unfold their effect, the sliding phase is at least briefly abruptly interrupted or disturbed; i.e. There is a so-called plucking of the ski during the sliding phase, which is extremely unpleasant for the user. In addition, in the embodiment of DE 211 07 37 A with extending through the tread layer through recesses also disadvantageous that the tread layer - seen across the width of the ski - is interrupted and therefore between the lateral boundaries of the recess and the back-inhibiting elements used water can penetrate through the capillary action. This often leads to icing of these areas, whereby a functionality in practical use is not guaranteed.
    A similar embodiment of a ski is known from FR 2 234 909 A, in which also two groove-shaped recesses are provided, in which fur inserts can be used. Again, the Rückgleithemmende effect abruptly, so that the risk of plucking the ski during the sliding phase is significant.
    Object of the present invention is therefore to provide a ski with which a harmonious transition between sliding and climbing phase is made possible and with which an abrupt onset of Rückgleithemmenden effect during the sliding phase is avoided as possible.
    According to the invention this is achieved in a ski of the initially mentioned type in that a front end and / or rear end of a groove-shaped recess is spaced from the front end and / or rear end of the other recess in the longitudinal direction of the ski.
    Due to the staggered arrangement of the front end and / or rear end of the two groove-shaped recesses of two preferably substantially mutually parallel recesses, the effect of optionally used in the groove-shaped depressions Rückgleithemmenden elements does not occur simultaneously. Rather, at first only the Rückgleithemmende effect of the element occurs, which is arranged in the groove-shaped recess whose front end is closer to the tip of the ski or whose rear end is located closer to the ski end. The Rückgleithemmende effect of the other element occurs in the area in which the beginning of the depression is closer to the ski center, during the movement added at a later time, so that a harmonious transition between sliding and climbing phase is achieved. The risk of unwanted, abrupt onset of the climbing aid due to a body weight shift or due to uneven track during the gliding phase, i. a so-called plucking of the ski, is thus significantly reduced.
    The groove-shaped depressions provided in the tread layer are in this case in the middle region, i. preferably arranged in the middle third of the ski, which extends over about 30 to 60% of the total ski length. Preferably, the groove-shaped recesses extend substantially over the entire central region.
    In order to achieve a particularly harmonious transition between sliding and climbing phase, it is advantageous if both the front and the rear ends of the groove-shaped depressions are arranged offset from each other in the longitudinal direction of the ski. This is achieved in a simple manner in that the at least two groove-shaped recesses have substantially the same length.
    In order to avoid water buildup between an inserted re-horsemem element and the tread layer, which can disadvantageously lead to ice formation, it is favorable if the recesses each have a groove bottom in the tread layer, wherein the groove bottom is formed by the continuous tread layer. This ensures that the tread layer also extends over the entire ski width in the region in which the groove-shaped depressions are provided, so that accumulations of water and an associated risk of icing with respect to through recesses can be significantly reduced.
    In order to easily enable the formation of groove-shaped depressions in the tread layer which do not extend through the entire tread layer, it is advantageous if the tread layer in the middle region, in particular in the rise zone, has a greater thickness than in a front and / or. or rear sliding portion. As a result, the groove-shaped depressions for receiving the slip-back inhibiting elements can be easily removed, e.g. be made by milling. Of course, other variants for forming the depressions, e.g. the provision of groove-shaped depressions in a core, in which the tread material penetrates during compression of the ski - as known per se - possible.
    With regard to a structurally expedient embodiment, in which the tread layer has a sufficient thickness for forming the groove-shaped depressions for receiving the anti-return elements, it is advantageous if the tread layer in the central region 1 mm to 5 mm, preferably 2 mm to 4 mm, in particular essentially 3 mm thick.
    As far as the front and rear sliding portions have a substantially constant first thickness and the central area of the tread layer has a substantially constant second thickness, a material-saving configuration results in the front and rear sliding portions, i. outside those regions in which the groove-shaped recesses are provided, and at the same time in that region of the ski, i. in the central region, in which the groove-shaped depressions are to be provided in the tread layer, sufficient material is present to incorporate the groove-shaped depressions, which do not penetrate as far as a lower belt of the ski.
    With respect to a homogeneous transition between the sliding portions, in which the tread layer has a smaller thickness and the central area in which the tread layer has a greater thickness, it is advantageous if the tread layer between the front and rear sliding portion and the central region each have a wedge-shaped transition region having.
    In order not to adversely affect the strength of the ski at the same time, it is advantageous if a lower belt adjacent to the tread layer is adapted to the different thicknesses of the tread layer. Advantageously, not only the course of the lower belt, but also the lower surface of the core material, which adjoins the lower belt is adapted to the over the longitudinal extent of the ski changing material thickness of the tread layer, so that a compact, high strength having Ski is achieved.
    With regard to an inexpensive and efficient production of the ski, it is advantageous if the tread layer has several parts, in particular a tread front part, a Laufflä chenhinterteil and a tread center part with the at least two groove-shaped depressions. It is particularly advantageous if the tread front part and the tread rear part are substantially conventional tread layers with constant thickness, however, the tread center part advantageously has on the one hand the wedge-shaped transition regions to the tread front part and tread rear part and a central portion with the groove-shaped recesses.
    In order to enable a particularly harmonious transition between the sliding and the rising phase, it is advantageous if a groove-shaped depression has a greater depth in a front area seen in the longitudinal direction of the ski, in particular in the first third of the longitudinal extent than in the remaining area the region of greater depth is preferably wedge-shaped tapering towards the rear. This ensures that - with appropriate coordination with the used back-slipping-inhibiting element - in the foremost region of the depression, the effective effective surface of the inserted anti-backlash element initially does not protrude over a tread plane defined by the tread layer. Only after the foremost area, the active surface of the anti-backlash element begins to protrude increasingly in the direction of the ski over the tread plane.
    Furthermore, it is favorable if at least one groove-shaped depression has a smaller depth than in the remaining region in a rear region seen in the longitudinal direction of the ski, in particular in the last third of the longitudinal extent, wherein the region of lesser depth is preferably designed wedge-shaped tapering towards the rear. This results due to the reduced depression in the rear section that the active surface of a recorded in the recess Rückgleithemmenden element in the rear area a higher effect, preferably in the manner of a repelling edge, unfolds.
    Tests have shown that it is favorable for avoiding the unwanted insertion of the anti-backlash effect of elements inserted in the groove-shaped recesses when the front and / or rear end of the groove-shaped recesses in a
    Spaced from each other by 20 to 150 mm.
    With regard to a uniform course of the anti-backlash effect, it is advantageous if all groove-shaped recesses have substantially the same length and the same width.
    In the prior art a variety of anti-rebar elements are known as climbing aids, which have different advantages depending on the application. Accordingly, depending on the application, a fur strip, a film strip with a back-inhibiting profile or a climbing wax, a rubber-filled plastic film or the like can be provided according to the invention as a back-restraining element.
    In order to be able to provide a ski according to the invention with different anti-backlash elements in the groove-shaped depressions, it is favorable if the anti-backlash element is detachably connected to the running surface, in particular by means of a pressure-sensitive adhesive, a hook-and-loop fastener connection or the like.
    The invention will be explained in more detail below with reference to preferred embodiments, to which, however, it should not be limited. In detail, in the drawings:

    Fig. 7a partially a longitudinal section of an alternative embodiment; and
    Fig. 7b partial longitudinal section according to Fig 7a with a used climbing skin.
    In Figure 1, a ski 1 is shown from below, i. It can be seen a view of the tread 2, which is formed from the underside of a tread layer 3.
    The ski 1 has a ski tip or a front end 4 and a ski end 4 a, which is arranged in the running direction at the rear end of the ski 1. In a sliding phase of the curved in side view in a known manner Ski 1 is brought into contact with the snow in two sliding portions of the tread 2, wherein the sliding portions of a front sliding portion 5 in the front third of the ski and a rear sliding portion 6 in the rear third make up the ski.
    Between these two sliding portions 5, 6, a central region 7 is provided, in which a riser zone is provided. In this central region 7, the tread 2 comes in particular at full (weight) load, i. especially during repelling, in contact with the ground. The middle region 7 preferably extends over approximately 30 to 60% of the ski 1 and in any case encloses the middle of the ski 1 relative to the longitudinal extent of the ski.
    As can be seen in FIG. 1, a total of three groove-shaped recesses 8 are provided in this middle region 7, which extend in the longitudinal direction of the ski 1 with a substantially constant width. However, the three groove-shaped recesses 8 do not set - as usual in the prior art - at the same place, but a front end 9 of a groove-shaped recess 8 is offset from the front end 9 of a further groove-shaped recess 8 is arranged. The distance between the front ends 9 of the groove-shaped recesses 8 is preferably between 20 and 150 mm.
    As can further be seen, all recesses 8 have the same length, so that rear ends 10 of the groove-shaped depressions 8 are also arranged offset from each other. With the aid of this staggered arrangement of the beginning or end of the groove-shaped depressions 8, a harmonious transition between sliding and climbing phase is achieved and the risk of abrupt insertion of the elements or climbing aids 11 (optionally FIG. By an unwanted body weight shift or by bumps during the sliding phase, which leads to so-called plucking of the ski is reduced.
    In Fig. 2, a further embodiment with three groove-shaped recesses 8 is shown, in which case the front end 9 of two lateral recesses 8 are arranged substantially at the same height. However, the front and rear ends 9, 10 of a third, in the middle arranged groove-shaped recess 8 is arranged offset from the other two wells.
    A similar embodiment is shown in Fig. 4, in which case the central recess 8 seen in the direction opposite to the two side recesses 8 is offset to the rear. That the front end 9 of the central recess 8 is arranged further back, so that - with the same length of the recesses 8 - the rear end 10 of the central groove 8 ends closer to the ski end 4a, as the rear ends 10 of the lateral recesses eighth
    Fig. 3 shows a further embodiment with only two, offset in the longitudinal direction of the ski mutually arranged groove-shaped recesses 8. Again, the recesses 8 substantially the same length, so that both the front and the rear end 9, 10 of the two grooves offset from one another.
    In all the exemplary embodiments according to FIGS. 2, 3 and 4, at least two groove-shaped recesses 8 are thus arranged offset to one another in the longitudinal direction of the ski as in the exemplary embodiment according to FIG. 1, so that the effects according to the invention described above in connection with FIG. 1 are also realized.
    In the exploded sectional view according to FIG. 5, it can be seen, in particular, that the groove-shaped depression 8 does not only extend through the entire tread layer 3 in the middle region 7, but rather that the groove base 12 is formed by the tread layer 3 itself. This also results in the region of the groove-shaped depressions 8 advantageously a continuous tread layer 3, in which optionally Rückgleithemmende elements 11 can be used.
    In the embodiment shown, the tread layer 3 is designed in three parts with regard to an efficient and cost-saving production and consists of a tread front part 3a, a tread rear part 3b and a tread center part 3c together. The tread front part 3a and the tread rear part 3b in this case have a constant material thickness, wherein the material thickness preferably, as is customary for tread documents, is approximately 1 to 1.2 mm. The groove-shaped recesses 8, however, have a depth of preferably about 0.5 to 0.8 mm.
    To provide such groove-shaped recesses 8 in the tread layer 3 itself, i. Also, as the groove bottom 12 to leave the tread layer 3 and thus to avoid interruption of the tread layer 3, the tread center part 3c is formed reinforced and has a constant thickness of up to 5 mm in the central portion. In the front and rear end portions of the tread center part 3 c wedge-shaped portions 13 are provided, in which material thickness is constantly reduced / increased, so that the thickness of the tread layer of the maximum thickness in the central portion of the tread center part 3 c at the ends of the tread center part 3 c to the thickness or Height of the tread layer 3a, 3b in the front and rear sliding portion is adjusted.
    As further shown in Fig. 5, the ski 1 shown has a structure known per se, i. The tread layer 3 is adjoined by a lower belt 14, to which in turn the ski core 15 is continued by a tip insert 16 in the front end region and by an end insert 17 in the rear end region. Above the core 15, an upper belt 18 is again provided in a conventional manner.
    As can be seen in FIG. 5, the arrangement or the course of the lower belt 14 is adapted to the material thickness of the tread layer 3 that changes over the ski longitudinal direction. Likewise, the underside 15a of the ski core 15 is adapted to the changing material thickness of the tread layer 3, so that a compact layered structure of the ski 1 results with changing material thickness of the tread layer 3.
    6a and 6b show in part a section through the tread layer 3, in particular the tread center part 3c, wherein it can be seen here that the groove-shaped recess 8 can have a larger depression in the front region, in particular in the foremost one third, which then drops constantly to the rear, so that the groove-shaped recess 8 tapers towards the rear wedge-shaped.
    This ensures that the climbing aid shown in Fig. 6b used in the inserted state, used as Rückgleithemmendes element 11 in the front portion not or only slightly protrudes beyond the tread plane defined by the underside of the tread layer 3. To the rear, i. seen in the direction of the ski end 4a, then projects an effective surface of the climbing aid initially slightly and then continuously to a greater extent on the tread plane. This leads, in particular in combination with the staggered arrangement of the depressions 8, to a particular harmonic transition between sliding and climbing phase, and thus an abrupt onset of the climbing aid can be avoided even better.
    In FIGS. 7a and 7b, it can further be seen that the groove-shaped depression 8 is also tapered in the rear region, in particular in the last third, towards the rear end 10 of the groove-shaped recess 8, ie. falls back towards the ski end 4a, so that the Rückgleithemmende element 11 and the climbing aid in the rear end of the groove-shaped recess 8 protrudes increasingly over the tread plane and thus unfolds in this area an improved Rückgleithemmende effect.
    As Rückgleithemmendes element 11 may be provided any known per se elements - in particular - as shown - strips of fur or a film strip with a Rückgleithemmenden profile or a climbing wax as well as a rubber-filled plastic film or the like. Preferably, the Rückgleithemmende element 11 is detachably connected to the tread 3, wherein the Rückgleithemmende element 11 in particular a carrier or. Compound layer 11a and an effective area having effective layer 11b provides. The connecting layer 11a can in this case on the groove base 12 facing surface connecting elements, e.g. in the form of a hook and loop fastener, or a pressure-sensitive adhesive layer or the like, in order to reliably hold the anti-backlash element 11 in the recess 8 during use of the ski 1 and, on the other hand, allow easy replacement, advantageously allowing individual adaptation to different applications ,
