Field of the invention
[0001] The present invention relates to the sport of skiing and more precisely relates to
a monoski and to the ski-boots binding system thereof to allow a monoski skiing.
Background of the invention
[0002] Two types of monoski are known, i.e. sport equipment consisting in a single ski having
a couple of ski-boot bindings so that the skier can go downhill on the snow with a
single ski.
[0003] A first type of monoski provides two parallel bindings arranged longitudinally on
the ski. A second type of monoski is the snowboard, which provides a couple of bindings
parallel to each other but transversal to the ski, that consists in a board with larger
width than a normal ski.
[0004] It is an object of the present invention to provide a monoski with a ski-boot binding
system that is different from the snowboard and from the monoski with parallel longitudinal
bindings.
Summary of the invention
[0005] These and other objects are achieved from the monoski according to the invention
and from the binding system thereof the ski-boots, whose characteristic is that the
binding means are arranged aligned behind each other in longitudinal direction with
respect to the ski.
[0006] Preferably, the binding means comprise a front binding and a rear binding. The rear
binding has a rear plate located between ski and boot and with a heel of predetermined
height. This way the rear boot is arranged with sole inclined in longitudinal direction
with respect to the ski.
[0007] Also the front binding can have a front support plate that is arranged between the
ski and the boot.
[0008] To make easier skiing with stiff ski-boots the rear plate and the front plate have
an inclination on a transversal direction, so that each boot is inclined outwardly.
In the case wherein binding means are mounted for skiing with the right boot ahead
and left boot behind, the front plate has left thickness larger than the right thickness,
whereas the rear plate has right thickness larger than the left thickness. On the
other hand, if the binding means are mounted for skiing with the left boot ahead and
right boot behind, the binding means have front plate with the right thickness larger
than the left thickness and rear plate with the right thickness shorter than the left
thickness.
[0009] Both binding means comprise a toe piece and a heel piece. The toe piece of the rear
binding and the heel piece for front binding are as closer as possible to each other.
Advantageously they are integrated in a single intermediate piece. The intermediate
piece can be formed by the heel piece of the front binding wherein a toe piece for
the rear binding is made.
[0010] The front plate and the rear plate can be formed by a single plate element connected
to the ski. This single plate element is preferably shaped in order to have a front
plain portion inclined transversally and a rear portion raised longitudinally and
inclined transversally in direction opposite to the front portion.
[0011] In a possible different embodiment, the intermediate piece is slidably engaged with
respect to the ski, whereby the locking movement of the rear boot causes also the
front binding heel piece movement, since the intermediate piece is pushed by the rear
boot against the front boot, which is also engaged with the front binding toe-piece.
The intermediate piece is advantageously slidably engaged up to a snap-fit locking
in the skiing position, whereby if the rear boot is released the front boot remains
locked.

Description of a preferred embodiment
[0013] With reference to figure 1, a monoski according to the present invention, indicated
with the numeral 1, is used by a skier 2 that wears a right ski-boot 3 and a left
ski-boot 4. The right boot 3 and the left boot 4 are connected to the monoski 1 by
means of respectively a rear binding 5 and a front binding 6.
[0014] Binding means 5 and 6 are respectively connected to the monoski 1 aligned longitudinally
in rearward position towards the tail la and forward position towards the tip 1b,
respectively.
[0015] This way, the skier can ski with right boot behind the left boot so that the ski-boots
are aligned, in the position of figure 1. This position allows an ease skiing since
when making a turn the right knee follows the left knee.
[0016] Obviously, by reversing the binding means so that the front binding is for the right
boot and the rear binding is for the left boot, skiing is possible as well. When practising
at the beginning, the skier will choose the position with the left boot ahead or behind,
that fits best for him/her.
[0017] With reference to figure 2 and to figure 3, rear and front binding means 5,6 comprise
respectively a rear binding toe piece 25 and a front binding toe piece 26 as well
as a rear binding heel piece 35 and a front binding heel piece 36 for the ski-boots.
The rear binding 5 has also a rear plate 15 located between ski 1 and rear boot 3.
Rear plate 15 has a heel 15a of predetermined height whereby rear boot 3 is arranged
with sole inclined forward in longitudinal direction with respect to ski 1.
[0018] Also front binding 6 has a front support plate 16 that is arranged between ski 1
and front boot 4.
[0019] As shown in figure 4, ski 1 can be wider than a standard ski, for example with tail
1a of 12 cm, a central portion of 10 cm and tip 1b of 15 cm.
[0020] For making easier skiing with stiff ski-boots, rear plate 15 and front plate 16 have
an inclination on a transversal direction, shown in figures 8 and 9, so that the boot
3 and 4 are always inclined outwardly. In the case wherein binding means 5 and 6 are
mounted for skiing with the right boot 3 ahead and left boot 4 behind, front plate
16 has left thickness 16' larger than right thickness 16", whereas rear plate 15 has
right thickness 15" larger than the left thickness 15'. On the other hand, if the
binding means are mounted for skiing with left boot 4 ahead and right boot 3 behind,
the binding means have front plate 16 with right thickness 16" larger than left thickness
16' and rear plate 15 with right thickness 15" shorter than left thickness 15'.
[0021] With reference to figures 6 and 7, toe piece 25 of rear binding 15 and heel piece
36 of front binding 16 are integrated in a single intermediate piece 56. For example,
using a heel piece 36 like that of figures 2,3 and 5, toe piece 25 of figures 6 and
7 can be inserted in a seat made in heel piece 36 same. Obviously spring means for
a safety release of the rear boot can be provided that operate by rotating under stress
on toe piece 25 similar to those provided in front toe piece 26 of known art.
[0022] The front plate and the rear plate can be made, as shown in figures 6 and 7, by a
single plate element 100 connected to the ski and shaped in order to have a front
plain portion 16 inclined transversally like in fig. 8 and a rear portion 15 raised
longitudinally in 15a and inclined transversally in direction opposite to the front
portion like in fig. 9.
[0023] Alternatively to the above described examples, as shown in figure 10, intermediate
piece 56 can be slidably engaged with respect to ski 1, whereby the locking movement
for the rear boot 3 causes also the front binding heel piece 4 to move forward, since
the intermediate piece is pushed by the rear boot 3 against front boot 4, in turn
engaging with front binding tip piece 26. The slidable intermediate piece 56, once
reached the locking position indicated with a continuous line in figure 10, is locked
automatically by means of a click mechanism not shown, and that can be unlocked by
skier 2 once released the rear boot 3. If the rear boot is released 3 front boot 4
can remain locked for running like a scooter.
[0024] The monoski according to the invention is new with respect to a monoski with parallel
bindings and has the following advantages. First of all skiing with sharp turns is
allowed owing to the advantageous position of the legs and to the width of the ski.
Furthermore, when releasing a boot the movement like a scooter is allowed in case
of plain snow fields or slight slopes, or for catching ski-lift means. In fact, the
boot that remains fastened to the ski is centred transversally with respect to the
ski and does not the cause lateral inclination.
[0025] In case of fall it is possible to get up easily even when both ski-boots are locked.
Finally, with respect to the normal two parallel skis, the advantages of any monoski
are present in case of fall, since not possibility to sprain the knees because the
legs cannot divaricate.
