[0001] The object of the invention is a method of applying a covering by sticking it on
the upper face of a ski. The object of the invention furthermore is a device for carrying
out the said method, and a ski with its upper face provided with a covering that has
been applied according to the said method, preferably with the aid of said device.
[0002] The invention aims to permit the application of a covering on the upper face of a
ski pair, which is stuck thereon and consists of a covering foil mainly of plastics
material, particularly a self-adhesive foil, or the like, and wich is meant for giving
the ski pair a peculiar aesthetic appearance and/or for concealing any marks of wear
or injury.
[0003] According to the invention, on the upper face of a ski a covering is stuck, which
initially has a width dimension such as to cover the longitudinal upper corners of
the ski, and which then has its sides trimmed by means of cuts made in correspondence
of the upper surface of the ski, along the longitudinal corners of said surface, at
a slightly inward position with respect to said corners, the cut side portions of
the covering being subsequently removed.
[0004] For carrying out this method, the invention provides a device which consists of a
knife comprising a handle, a blade protruding from the handle, and a projecting blade-guiding
part extending from the handle beside the blade, beyond the sharp edge thereof, and
which is so spaced apart from the blade that when the projecting blade-carrying part
is caused to bear against one longitudinal side edge of a ski, the sharp edge of
the blade, turned toward the upper face of the ski, is at a distance from the respective
longitudinal upper corner of said ski.
[0005] One embodiment of the invention is shown in the annexed drawing, in which:
Figure 1 is a perspective view showing one embodiment of a device for carrying out
the method according to the invention.
Figure 2 is a vertical sectional view showing the use of the device illustrated in
Figure 1, for carrying out the method according to the invention.
[0006] In Figure 2 numeral 1 denotes the body of a ski to be provided on its upper face
with a covering for hiding any marks of wear and/or giving the ski a peculiar appearance.
The covering consists, for example, of an adhesive or self-adhesive plastics foil
2 which is stuck on the ski. The said covering foil 2 initially has a width dimension
which is greater than the width of the ski 1, so that once the foil has been applied
and stuck, the same not only covers the entire upper surface of the ski 1, but also
the longitudinal upper corners thereof, and extends downwardly from said corners,
so as to adhere on the longitudinal side edges of the ski 1, as shown with solid lines
in the left-hand side of Figure 2, and with dash-and-dot lines in the right-hand
side of said Figure 2.
[0007] Then the covering foil 2 having been thus applied to the ski 1, is trimmed, that
is, it has both of its sides cut in correspondence of the surface of ski 1, along
and parallelly to the longitudinal corners thereof, at a position more or less away
from these corners in the direction of the median longitudinal axis of the ski 1.
[0008] Finally, the strips cut from the sides of the covering foil 2 are removed, i.e.,
they are detached and withdrawn, so that both the longitudinal side edges and the
respective upper corners of the ski will be again exposed. A ski 1 is thus obtained,
with its upper face provided with a screening and/or peculiar covering made, for example,
of an adhesive plastics foil 2, and having a width dimension which is smaller than
the width of the ski 1, so that in the transversal direction this covering terminates
at a short distance from the longitudinal upper corners thereof, whereby the said
covering cannot become detached, raised, or broken, as it would occur if the longitudinal
lateral borders of the covering foil 2 should extend also on the longitudinal upper
corners and the longitudinal side edges of the ski 1.
[0009] The above-disclosed method also permits to apply the covering foil 2 to a ski 1 without
having to specially profile beforehand the covering foil 2, and without having to
perform any particular operation for exactly aligning the longitudinal borders of
said foil 2 with the longitudinal edges of the ski 1, thence with no particular care
and exertion, and nextly permits by means of a simple longitudinal trimming of the
foil sides, to correctly adjust the outline of the covering foil 2 to the shape of
the ski 1, and to obtain a precise parallelism and spaced apart relation between the
longitudinal borders of the applied covering foil 2 and the longitudinal upper corners
of the ski 1. Moreover, a covering foil 2 of a suitable width can be used for variously
wide ski 1.
[0010] Preferably, a device is used for longitudinally trimming the sides of the covering
foil 2 having been applied to the ski 1, and this device consists of a knife comprising
a handle 3 and a blade 4 protruding from one and of handle 3, and preferably having
a pointed-end sharp edge. From handle 3, a projecting blade-guiding part 5 extends
parallely to the blade 4 at a certain distance therefrom, and is longer than the blade
4, so that it protrudes from the handle 3 beyond the free end of said blade 4.
[0011] To trim the covering foil 2 having been applied to the ski 1, the projecting blade-guiding
part 5 of the knife is caused to bear against the respective longitudinal side edge
of the ski 1, while the pointed-end sharp edge of blade 4 pierces the covering foil
2 in correspondence of the upper face of the ski 1, at a certain distance from the
respective longitudinal upper corner thereof, as shown in the left-hand side of Figure
2. The knife is then moved along the ski 1, and its projecting blade- guiding part
5 is kept always bearing against the longitudinal side edge of said ski 1. Such a
trimming therefore is extremely accurate and fast, and can be effected with no difficulty
even by unskilled persons.
[0012] The distance of the cut and then of the longitudinal lateral border of the covering
foil 2 from the respective longitudinal upper corner of the ski 1, depends on the
distance between the blade 4 and the projecting blade-guiding part 5. In order to
have an alterable distance, the above-disclosed knife may be also made in such a manner
as to permit to modify within certain limits the distance between the blade 4 and
the projecting blade-guiding part 5. To this end, the knife may, for exemple, consist
of a U-bent lamina with one of its arms being shorter and having its estremity made
in form of a blade, or carrying a blade, while its other arm is longer and its extremity
constitutes or carries the projecting blade-guiding part, and the distance between
the two arms can be modified by means of a forcing-apart screw.
[0013] Of course the blade 4 may be secured, such as in the shown embodiment, to the handle
3 either in a fixed or exchangeable manner, with the aid of any suitable means.
