Description

The invention relates to a fastening device for a ski skin and a ski with a ski skin, having a retaining part which is connected to one end of the ski skin and can be pushed onto the tip of the ski, the retaining part having at least one opening through which a band which is fastened on the ski skin can be drawn.
Devices for fastening a ski skin, also referred to as a climbing skin, on cross-country skis have been known for some time now. The ski skin is usually fastened in a releasable manner both on the tip and at the rear end of the ski. In addition, the ski skin is usually designed as an adhesive skin. For mounting purposes, the ski skin is first of all fastened on the tip of the ski and then adhesively bonded to the underside of the ski. Finally, the skin is also fastened at the end of the ski using a suitable device. The skin here must not be tensioned to the extent where it detaches from the ski, but the front end of the skin has to be fastened securely on the tip of the ski. In particular in the case of competitions in. which it is desirable for the ski skin to be removed as quickly and easily as possible, the ski skin is fastened merely on the tip of the ski.
A fastening device of the type mentioned has been disclosed, for example, from DE-A-924 496. This fastening device has a so-called tightener which, at a front end, has an eyelet through which a tensioning belt is drawn, this tensioning belt being connected to the ski skin, for example riveted thereto, at one end. At the other end, the tensioning belt is fastened on a tightening lever, which is flipped over for tensioning purposes. In order for the tightener to be fixed on the tip of the ski, it has side tabs which engage around the tip of the ski laterally. This fastening device has the disadvantage that it has to be designed precisely for the corresponding shape of the ski tip. Since a very large number of different shapes of ski tip are produced, a correspondingly large number of different retaining parts would have to be produced and kept in stock.
A fastening device for a ski skin has also been disclosed from CA-A-2332217. This device, however, serves, in particular, for fastening the ski skin at the end of the ski. The same applies to the fastening device according to CH 673 399.
The Applicant's EP-A-1 329 245 discloses a further fastening device. In the case of the latter, a ski cap has a through-passage into which a fastening part is latched from the underside of the ski. This device has proven successful for cross-country skiing, but involves comparatively great outlay to produce.
FR 2 792 213 has disclosed a fastening device which, on the underside of the tip of the ski, has a flap beneath which a wedge-shaped part of the ski skin can be fixed. It is also the case here that different shapes of ski tip require different fastening devices.
The object of the invention is to provide a fastening device of the type mentioned which avoids the abovementioned disadvantages. The intention is for this fastening device to be suitable, in particular, for competitions and thus to be easy and quick to use.
This object is achieved, in the case of a fastening device of the generic type, in that a cap, on which the pushed-on retaining part is retained in a releasable manner, is fastened on the tip of the ski. The fastening device according to the invention can be used to fix the ski skin on the tip of the ski. It is possible to compensate for a change in length of the skin by adjusting the band. A cap, on which the retaining part is retained, is fastened on the tip of the ski. The cap thus forms a guide and mount for the retaining part. Such caps may be designed in such a way that they can be positioned on different shapes of ski tip. It is thus possible to use the same retaining part and the same cap for different shapes of ski tip.
According to a development of the invention, it is provided that the cap has a central recess into which the retaining part can be pushed from the front. The cap may be produced from two parts which are fastened at a distance apart from one another on the tip of the ski and in the case of which the abovementioned recess is formed by an interspace between these two parts. However, it is also possible, in principle, for the cap to be produced from a single part. The cap can be screwed, clamped or latched onto the tip of the ski. Finally, the cap can be shrink-fitted onto the tip of the ski or glued to the tip of the ski.
According to a development of the invention, it is provided that the retaining part can be latched on the cap. The retaining part is thus fixed particularly securely on the tip of the ski and, nevertheless, can be easily released.
According to a development of the invention, it is provided that the retaining part has, on the underside of the ski, an opening through which the band can be drawn. In addition, a second, L-shaped opening is preferably provided on the top side, and the band can likewise be drawn through this opening. This allows easy fastening of the band and tensioning by pulling at a projecting end of the band.
According to a development of the invention, it is provided that the retaining part is fastened for tilting action on the ski in order for the ski skin to be released. This allows the skin to be removed particularly easily and quickly. It is preferable here for a projecting end of the band to form a grip, by which the retaining part can be gripped and tilted over the tip of the ski and thus released.
Further advantageous features can be gathered from the dependent patent claims, from the following description and from the drawing.
Exemplary embodiments of the invention are explained in more detail hereinbelow with reference to the drawing, in which:
FIG. 1 shows a three-dimensional view of a retaining part,
FIG. 2 shows a further view of the retaining part
FIG. 3 shows a section through the retaining part along line III-III from FIG. 2,
FIG. 4 shows a further view of the retaining part,
FIG. 5 shows a three-dimensional view of the tip of a ski with a variant of a fastening device according to the invention,
FIG. 6 shows a further view of the tip of the ski with the cap placed in position but without a retaining part,
FIG. 7 shows a view of the tip of the ski, and
FIG. 8 shows a further view of the tip of the ski with the cap placed in position but without a retaining part.
The fastening device has a retaining part 1, which is shown in FIGS. 1 to 4 and is produced, preferably in a single piece, from plastic. This retaining part 1, according to FIG. 6, with a ski skin 6 fastened on a tip 3 of a ski 2, is integrated in a releasable manner in a cap 7. According to FIG. 7, a band 9 is fastened on the ski skin 6, for example by rivets (not shown here) or by adhesive bonding. If the band 9 is adhesively bonded to the ski skin 6, the band 9 is designed to be wider at the adhesive-bonding location, this resulting in a comparatively wide adhesive-bonding surface. This band 9 is drawn through openings 12 and 13 (FIG. 3) of the retaining part 1 and has one end 9 a projecting out of the retaining part 1 on the top side 4 of the ski.
The retaining part 1, according to FIG. 3, is of hook-like design and has a recess 16 which accommodates a front region of the tip 3 of the ski. This recess 16 contains a first opening 12 which, in the mounted state, is arranged on the underside of the tip 3 of the ski and through which the band 9 is drawn, as, in particular, FIG. 5 shows. On a semicircular front surface 15, this band 9 is deflected through 180° and drawn through a second opening 13. At the inlet of this opening 13, the retaining part 1 has a plurality of teeth forming an edge 14. The opening 13, according to FIG. 3, is of approximately L-shaped design in cross section, so that the band 9 is deflected through approximately 90° in this opening 13. The edge 14 is designed such that it allows the band 9 to be drawn through the opening 13, but prevents movement in the opposite direction when the band 9 has been tensioned. The band 9 can thus be tensioned in a stepless manner.
The cap 7 is fastened on the tip 3 of the ski, for example it is screwed to the tip by screws (not shown here). However, other fastening means are also conceivable. According to FIG. 8, the cap 7 has two sections 7 a and 7 b, between which is arranged a recess A into which the retaining part 1, according to FIG. 6, is pushed. The sections 7 a and 7 b each have, according to FIG. 8, a surface 17, these surfaces running parallel to, and being laterally offset in relation to, the longitudinal axis of the ski 2 and having the retaining part 1 guided and retained on them. In this region, the tip 3 has a transversely running rectilinear edge 5, against which the retaining part 1 butts by way of the recess 16. The pushed-on retaining part 1 is thus retained and guided between the cap regions 7 a and 7 b, as FIG. 7 shows.
The cap 7, according to FIGS. 1 to 3, has, at a top front end, a latching protuberance 10, which forms a latching connection with a latching element 11 of the cap 7, this latching element being shown in FIG. 8. The latching element 11 is formed by a recess on a crosspiece 8 which connects the two sections 7 a and 7 b. The cap 7 is thus formed in one piece. However, it would also be possible here for the latching protuberance 10 to be arranged laterally. The latching connection with the protuberance 10 and the latching element 11 is designed such that, when the retaining part 1 is pushed onto the tip 3 of the ski, the latching connection can be made, for example, by virtue of the retaining part 1 being pivoted and can be released by a corresponding movement in the opposite direction.
FIG. 5 shows a retaining part 1′ in which two laterally arranged latching protuberances 10′ are provided. The cap 7′ which is provided therefor has correspondingly, in a recess 7′, two mutually opposite latching elements 11′, as, in particular, FIG. 6 shows. It is also the case with this configuration that the retaining part 1′ is pushed onto the cap 7′ from the front and latched by virtue of a tilting movement, the protuberances 10′ being latched in a releasable manner into the latching elements 11′. In order to release the latching connections, the retaining part 1′ is raised at the end 9 a of the band and tilted forwards and, finally, released from the cap 7′.
The handling of the fastening device is explained in more detail hereinbelow.
In order to fasten the ski skin 6 on the ski 2, the retaining part 1 is pushed onto the tip 3 of the ski from the front, so that the retaining part 1 ends up located between the two cap sections 7 a and 7 b. The retaining part 1 here is guided by the surfaces 17. By virtue of a pressure being exerted on the pushed-on retaining part 1, the latter, finally,. is latched on the cap 7. The retaining part 1 is thus finally located, according to FIG. 6, on the tip 3 of the ski, the end 9 a of the band projecting on the retaining part 1. This end 9 a of the band may be of comparatively stiff design, so that it butts against the top side 4 of the ski. The ski skin 6 is then positioned on the underside of the ski in a manner which is known per se and, by virtue of the adhesive layer of the ski skin 6, the latter adheres correspondingly to the ski 2. Pulling the end 9 a of the band then results in the band being tensioned, so that the front end of the ski skin 6 butts against the tip 3 of the ski. The retaining part 1 is correspondingly supported on the tip 3 of the ski and butts against the same.
If the ski skin 6 is to be removed, then the end 9 a of the band is gripped and drawn forwards and upwards away from the top side 4 of the ski. The retaining part 1 can thus be tilted forwards over the edge 3 a of the tip 3 of the ski and thus released from the tip 3 of the ski. The latching connection between the latching protuberance 10 and the latching element 11 is released in this case. The ski skin 6 can then be drawn off from the ski 2. The actions of fastening and releasing the ski skin 6 can thus be carried out straightforwardly and very quickly. Positioning the retaining part 1 on the cap 7, in addition, results in the ski skin 6 being fastened very securely at its front end. The retaining part 1 is protected by the two regions 7 a and 7 b and by the cap 7 and cannot readily be released, for example, by being hit. The abovementioned latching connection forms a further safeguard against an undesired release action of this type. The configuration according to FIGS. 5 and 6 is used in the same way.
