Description
[0001] The invention relates to a sliding board, in particular a
ski, with a running surface, an upper shell, a core, steel edges,
and with at least one interface element, connected to the sliding
board body by means of anchoring elements, for arranging at least
one binding element on the upper side of the sliding board.
[0002] The invention also relates to a method for the production of
a sliding board, in particular a ski, consisting of a running
surface, steel edges, a prefabricated core, an upper shell,
optional additional intermediate plies, and also with at least one
interface element for arranging at least one binding element on the
upper side of the sliding board, the sliding board being pressed
together in a mold under pressure and heat.
[0003] A sliding board with a profiled rail system which consists
of at least one rail extending in the longitudinal direction of the
sliding board, which is connected to the sliding board body by a
dowel connection or dowel anchoring via at least one formed-on
dowel or dowel portion, is known from EP-A-1 161 972. A number of
pegs designed as expansion dowels, which are slotted and have a
bore which narrows toward the free end of the peg concerned, are
formed on the profiled rails following one another in the
longitudinal direction of the rail. The bores are also open to the
upper side of the profiled rail. After the rail has been attached
to the ski body and also after the pegs have been inserted into
bores provided correspondingly on the ski body, pins are pressed or
driven into the narrowing part of the bores, expanding the pegs.
This type of fastening replaces the otherwise usual screw
fastening.
[0004] The object of the invention is to provide a sliding board in
which subsequent fastening of interface elements, in particular
profiled rails, to the finished sliding board is no longer
necessary.
[0005] According to the invention, the object set is achieved by
virtue of the fact that the anchoring elements have already been
inserted into receiving holes of the core during sliding board
production and integrated here by material which cured during
pressing together of the ski.
[0006] In a variant of the method according to the invention,
receiving holes are made in the core and openings are made in the
upper shell and also the optional additional plies provided above
the core, a curing material is introduced into the receiving holes
of the core, the interface element is positioned in the holes and
the receiving holes by means of anchoring elements, the sliding
board is ready constructed and pressed together in a mold, so that
during the pressing operation the material introduced into the
holes cures and integrates the anchoring elements in the core.
[0007] In another variant of the method according to the invention,
two receiving holes are made in the core and openings are made in
the upper shell and also the optional additional plies provided
above the core, a prepreg layer being positioned on the core, at
least in the region of the receiving holes, the interface element
is positioned in the holes and the receiving holes by means of
anchoring elements, and the sliding board is ready constructed and
pressed together in a mold, so that during the pressing operation
the resin of the prepreg layer flows into the receiving holes,
cures and integrates the anchoring elements in the core.
[0008] In the invention, the interface element(s) is (are)
accordingly already firmly integrated during production of the
sliding board, and subsequent fastening is no longer necessary. The
production of the sliding board is possible in a simple way, and
only the binding--ski binding or snowboard binding--remains to be
arranged on the finished sliding board.
[0009] In a preferred embodiment of the invention, the cured
material is at the same time also a material which forms a
connection to the core, to the upper web and to the anchoring
elements. Such a material is an adhesive, a resin or the like, for
example.
[0010] In another especially advantageous variant embodiment, the
cured, connecting material originates from a prepreg layer
introduced above the core. In this embodiment, a separate adhesive
or the like does not have to be introduced into the receiving holes
of the core during production of the sliding board.
[0011] According to another embodiment of the invention, the cured
material retaining the anchoring elements in the ski can also be
one which retains the anchoring elements merely by a positive
connection.
[0012] In all the variant embodiments, the integration of the
anchoring elements in the ski must ensure that the binding arranged
on the interface elements can be loaded accordingly. It is
therefore advantageous to enlarge the connection or contact surface
of the cured material with the upper web, to expand its area
slightly, which can be effected by virtue of the fact that the
holes made in the core are widened accordingly in their edge
region.
[0013] All kinds of core which can be provided with the receiving
holes, therefore prefabricated foamed cores, wood cores, cores made
of metal and the like, are suitable for producing sliding boards
according to the invention.
[0014] An upper shell which is already premolded can also be used
in the production of the sliding board.
[0015] Further features, advantages and details of the invention
are described in greater detail with reference to the drawing,
which shows illustrative embodiments diagrammatically and in
which
[0016] FIG. 1 shows a cross section through an embodiment of a ski
according to the invention, and
[0017] FIG. 2 shows a partial cross section through another
embodiment of a ski.
[0018] FIG. 1 shows a cross section through an embodiment of a ski
1 which comprises a core 2, an upper shell 3 forming or enclosing
the upper side of the ski and the two longitudinal sides of the ski
1, a running surface 4 and edges 5 made of steel. A ply reinforcing
the ski structure, a lower web 6, is provided between the running
surface 4 and the core 2. The upper shell 3 can be of single-ply or
multi-ply design, and at least one further intermediate ply, for
example an upper web, can be introduced between the upper shell 3
and the core 2.
[0019] For the arrangement, guidance, slidable displacement and the
like of a ski binding or ski binding part--a front jaw or a heel
jaw--guide elements 7 with a rail-like profile are retained on the
upper side of the ski 1. The guide elements 7 have been integrated
into the ski structure during production of the ski 1, as is
described below.
[0020] Each rail-like guide element 7 comprises in its region
facing its adjacent ski side surface a guide strip 7a extending in
the longitudinal direction of the ski, so that, for example, a base
plate or support plate of a ski binding or ski binding part can be
pushed onto the pair of guide elements 7. Each guide element 7 is
provided with a number of receiving bores 7b for the insertion of
anchoring elements 8. The anchoring elements 8 consist in
particular of a cylindrical shaft 8a and a likewise cylindrical
head 8b of greater diameter. The receiving bore 7b in each guide
element 7 is provided with an inwardly offset region 7c on which
the head 8b of the anchoring element 8 is supported when the latter
has been inserted. In the embodiment illustrated, that region
anchored in the ski 1 of the shaft 8a of each anchoring element 8
is provided with a peripheral groove 9. Instead of one groove, a
number of grooves, indentations or the like can be provided on the
shaft 8a of the anchoring element 8.
[0021] In those locations where the rail-like guide elements 7 are
positioned on the ski by means of the anchoring elements 8,
receiving openings 10, 10'--holes or bores--have been made in the
core 2, the diameter of which is greater than that of the shaft 8a
of the anchoring elements 8. The core 2 is preferably a
prefabricated foamed core, so that the receiving holes 10, 10'
concerned can be made in a simple way. The holes 10 are in
particular cylindrical bores, the holes 10', which are a possible
variant, are likewise cylindrical but are widened peripherally in
their upper edge region. Corresponding openings or holes 3a for
passing the anchoring elements 8 through have also been made in the
region of the upper shell 3 and the optionally present intermediate
plies.
[0022] The ski 1 is manufactured as follows from the individual
components, the prefabricated core 2 provided with the receiving
holes 10 and/or 10', the upper shell 3, the optionally provided
additional intermediate plies, the running surface 4, the steel
edges 5 and the guide elements 7.
[0023] The anchoring elements 8 positioned on the guide elements 7
are passed through the holes 3a in the upper shell 3 and through
corresponding holes of any further plies. In this connection, the
upper shell 3 can be used either already premolded into its
intended shape or unmolded. A connecting material 11, for example
an adhesive, a synthetic resin or the like is introduced into the
holes 10, 10' present in the core 2. The anchoring elements 8 are
then inserted into the receiving holes 10 thus prepared. The ski,
completed with all the components, is pressed together in an
appropriate mold while heat is supplied. In the process, the
connecting material 11 located in the receiving holes 10, 10' cures
and forms a firm connection of the anchoring elements 8 to the core
2. At the same time, the material 11 also penetrates the grooves,
indentations 9 or the like of the shaft 8a of the anchoring
elements 8. The material 11 is preferably also to form a connection
to the upper web 3, which is especially readily possible in the
case of receiving holes 10' with a widened upper region.
[0024] Instead of a connecting curing material 11, it is also
possible to introduce a material, for example a suitable plastic,
which only cures, and therefore does not form a connection to the
connection elements 8 or the core 2 and the upper web 3, into the
receiving holes 10, 10'. The material adapted to the receiving hole
10, 10' and the connection element 8 in the finished ski 1
consequently retains the anchoring element 8 concerned positively
in the ski 1.
[0025] FIG. 2 shows a further embodiment of a ski 1 with a
structure which corresponds essentially to FIG. 1, with a core 2, a
running surface 4, edges 5, a lower web 6 and an upper shell 3. The
design and arrangement of the guide elements 7, the anchoring
elements 8 and their accommodation in holes 11' correspond to the
variant shown in FIG. 1. A prepreg layer 14 provided with openings
for passing the connecting elements 8 through is introduced between
the core 2 and the upper shell 3 or the optionally present
intermediate ply at least in the region of the holes 11'. The layer
14 consists in a known manner of matting, made of glass fibers in
particular, impregnated with resin. The production of the ski 1
takes place similarly to that according to the first illustrative
embodiment with the difference that no connecting material is
introduced into the holes 10'. When the ski 1 is pressed together,
the liquefying resin of the prepreg layer 14 penetrates the holes
10', solidifies there and integrates the anchoring elements 8.
[0026] The invention is not limited to the embodiments illustrated
and described. The core 2 of a ski 1 embodied according to the
invention can also be made from other materials, for example wood
or light metal. The invention can also be applied to
snowboards.
[0027] It may also be mentioned that, instead of guide elements 7
with a rail-like profile, other interface elements can also be
provided between ski and binding.
