Description
[0001] 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.
[0002] 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.
[0003] 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.
[0004] 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.
[0005] 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.
[0006] 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.
[0007] 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.
[0008] 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.
[0009] 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.
[0010] 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.
[0011] 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.
[0012] 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.
[0013] Further advantageous features can be gathered from the
dependent patent claims, from the following description and from
the drawing.
[0014] Exemplary embodiments of the invention are explained in more
detail hereinbelow with reference to the drawing, in which:
[0015] FIG. 1 shows a three-dimensional view of a retaining
part,
[0016] FIG. 2 shows a further view of the retaining part
[0017] FIG. 3 shows a section through the retaining part along line
III-III from FIG. 2,
[0018] FIG. 4 shows a further view of the retaining part,
[0019] FIG. 5 shows a three-dimensional view of the tip of a ski
with a variant of a fastening device according to the
invention,
[0020] FIG. 6 shows a further view of the tip of the ski with the
cap placed in position but without a retaining part,
[0021] FIG. 7 shows a view of the tip of the ski, and
[0022] FIG. 8 shows a further view of the tip of the ski with the
cap placed in position but without a retaining part.
[0023] 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 9a
projecting out of the retaining part 1 on the top side 4 of the
ski.
[0024] 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.degree. 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.degree. 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.
[0025] 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 7a and 7b, between which is arranged a recess A
into which the retaining part 1, according to FIG. 6, is pushed.
The sections 7a and 7b 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 7a and 7b, as FIG. 7 shows.
[0026] 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 7a and 7b.
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.
[0027] 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 9a of the band and tilted forwards
and, finally, released from the cap 7'.
[0028] The handling of the fastening device is explained in more
detail hereinbelow.
[0029] 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 7a and 7b. 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 9a of the band projecting on the
retaining part 1. This end 9a 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 9a 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.
[0030] If the ski skin 6 is to be removed, then the end 9a 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 3a 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 7a and 7b 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.
