DESCRIPTION OF THE INVENTION
[0001] The present invention relates to the technical sector of ski bindings, in particular
bindings for Alpine skiing.
[0002] In greater detail, the invention relates to a ski stop device, destined to be mounted
on the ski in a position adjacent to a binding for Alpine skiing, in particular in
a forward position to a heel-piece for hooking the rear part of the ski boot to block
the ski.
[0003] Since safety bindings were introduced, able to unhook the ski boot from the bindings
when under unusual stresses, for example as a consequence of a fall, there has existed
a drawback regarding preventing the ski, following the unhooking, from falling along
the incline autonomously and uncontrolledly. The same drawback also exists when the
skis still have to be hooked to the ski boots.
[0004] With the aim of obviating the above drawbacks, ski-stoppers have been developed,
i.e. ski stop devices which are mounted on the ski adjacent to a binding, for example
a heel-piece.
[0005] In substance, the ski stop devices comprise a fixing element to the ski, which is
fixed to the ski so as to be adjacent to the heel-piece, in a forward position in
relation thereto, and a braking element which is conformed as a two-arm lever, where
a first arm of the lever is in the form of a fork having a pair of arms distanced
from one another by a greater distance than the width of the ski, and a second arm
of the lever is conformed so as to have a pair of prongs substantially parallel to
one another and at a prefixed reciprocal distance.
[0006] The braking element is preferably in a single body, with the two arms that are in
a single body with the pair of prongs, for example, in particular, the braking element
is formed by a metal rod bent and conformed so as to have, on one side (forming the
first arm of the lever arm) the pair of arms, and on the other side (which forms the
second arm of the lever) the pair of prongs, and a central part, for connecting the
arms and the prongs, which is coupled to the fixing element.
[0007] The braking element is hinged (in an intermediate part between the pair of arms and
the pair of prongs) to the fixing element so as to be oscillating about a hinge axis
transversal to the fixing element and thus transversal to the ski so as to be able
to assume at least two distinct configurations:
an operating configuration in which the arms of the fork can be arranged by the flank
of the ski, and in a lowered position with respect to the ski, with the aim of being
able to at least partially penetrate into the snow and thus provide a friction action
for braking the ski, while the pair of prongs is raised with respect to the ski,
and a non-operating configuration (I) in which the arms of the fork are raised with
respect to the ski in order to enable a sliding of the ski on the snow, while the
pair of prongs are lowered towards the ski.
[0008] Stop devices usually comprise a sort of plate which is coupled to the pair of prongs,
to form an abutment for the sole of the rear part of the ski boot.
[0009] The stop devices are conceived and predisposed in such a way that the braking element
is always active, i.e. is forced to be kept in the operating configuration, with the
arms of the fork kept lowered with respect to the ski and the pair of prongs, and
therefore the plate, kept raised with respect to the ski. In this way, when the ski
is not hooked to the ski boots, and thus potentially free to slide on the snow, the
stop device, kept in the operating configuration with the arms of the forks lowered,
provides a braking action.
[0010] When the skier hooks the ski boot to the ski, by lowering the rear part of the ski
boot against the ski to hook it to the heel-piece, the ski boot pushes the plate downwards,
and thus also push the pair of prongs downwards, causing the braking element to rotate
about the hinge axis thereof to the fixing element, consequently raising the arms
of the fork above the ski.
[0011] Some stop devices of known type include the use of springs to maintain the pair of
prongs (or the plate) raised from the ski, and thus maintain the braking element in
the operating configuration. When the rear part of the ski boot is lowered onto the
ski to hook to the heel-piece, the plate is pushed downwards to compress the springs;
when the ski boot is unhooked from the heel-piece, the springs will push the plate
upwards to return the braking element into the operating configuration.
[0012] Other stop devices of known type comprise a pair of recesses realised in the fixing
element, having a shape such as to accommodate internally thereof the pair of prongs
and a pair of guide walls, which are arranged below the recesses, to guide the prongs
towards the ski, forcing them to near one another. When the ski boot is lowered onto
the ski to hook to the heel-piece, the plate is pushed downwards, forcing the pair
of prongs to exit the recesses and go into contact with the pair of guide walls, the
shape of which guides the prongs towards the ski and forces the prongs to near one
another; when the ski boot is unhooked from the heel-piece, the prongs will tend to
return to the original reciprocal distance and will rise with respect to the guide
walls, to return internally of the recesses, thus bringing the braking element into
the operating configuration.
[0013] In substance, in this case the pair of prongs acts as a sort of spring.
[0014] In the case of uses of the stop devices associated to the ski bindings to be used
in the discipline of Alpine skiing, in which the skier ascends while keeping the skis
on his/her feet, specifications are required which deactivate the stop device, i.e.
maintain the braking element in the non-operating configuration, when the skier moves
uphill while wearing the skis.
[0015] In fact, in order to move upwards while wearing the skis, the skier keeps only the
forward part of the ski boot hooked to the forward binding, i.e. the toe-piece, while
the rear part of the ski boot is unhooked from the heel-piece.
[0016] In this way the skier can simulate a walking step, as the ski boot can be oscillated
with respect to the ski, in particular by raising the rear part of the ski boot.
[0017] By doing this, where the stop device is present, each time the skier raises the rear
part of the ski boot from the ski, the braking element will return to the operating
configuration by activating: this would obviously constitute an obstacle to the upwards
movement.
[0018] Some of the specifications at present used for maintaining the stop device deactivated,
i.e. maintaining the braking element in the non-operating configuration when the skier
desires to move uphill with the skis still attached, and thus after having unhooked
the rear part of the ski boot from the heel-piece, consist in the use of locking elements
which are activatable to abut the plate, or the pairs of prongs, and keep the plate,
or the pairs of prongs, lowered with respect to the ski and therefore the arms of
the fork raised with respect to the ski.
[0019] These blocking devices are, for example, constituted by levers or plates, hinged
to the fixing element of the stop device, or to other elements fixed to the ski, and
subjected to the action of the springs.
[0020] When the skier desires to move uphill with the skis at his/her feet, after having
unhooked the rear part of the ski boot from the heel-piece, he/she has to rotate the
levers or the plates so that they go onto the plate, or the prongs, and are blocked
in the lowered position against the ski, to maintain the braking element in the non-operating
configuration and deactivate the stop device.
[0021] The presence of these blocking devices (levers, plates and the like) constitutes
in any case a drawback as they have a non-insignificant volume and constitute a raising
of the ski boot, once they are activated to block and maintain the plate, or the prongs,
lowered towards the ski.
[0022] Consequently, should the skier, during an upwards walk, decide to hook the rear part
of the ski boot, for example so as to perform a short stretch in descent, or for other
reason, he or she would be in an impossible situation since the rear part of the ski
boot, once lowered towards the ski, will be in a raised position with respect to the
heel-piece due to the presence of the locking devices (levers, plates and the like).
[0023] A further specification at present used to deactivate the stop device, and thus maintain
the braking element in the non-operating configuration when the skier desires to cross
uphill stretches with the skis attached to his/her feet, consists in using the same
heel-piece to block and keep the plate or the prongs lowered towards the ski.
[0024] In this matter, the plate, or the prongs, must be pushed towards the ski and the
heel-piece must be rotated about a vertical axis to the ski so as to bring an appendage
thereof, or another abutment element, above the plate, to block it in the lowered
position towards the ski and maintain the arms of the fork raised with respect to
the ski, and thus maintain the braking element in the non-operating position by deactivating
the stop device.
[0025] This solution however is not practical, as the heel-piece has to be rotated, and
therefore the skier, when wishing to hook the rear part of the ski boot to perform
downhill stretches, or for other reasons, will first necessarily have to proceed to
returning the heel-piece into the original position thereof.
[0026] Document
EP 3.120.903 A1 discloses a ski stop device according to another prior art solution.
[0027] The aim of the present invention is therefore to provide a ski stop device that obviates
the drawbacks in the prior art as described in the foregoing.
[0028] In particular, an aim of the present invention is to provide a ski stop device able
to deactivate the braking element, i.e. maintain it in the non-operating configuration,
in simple and rapid ways, without requiring rotation of the heel-piece and without
having volumes such as to constitute lifting the ski boot.
[0029] The above aims are attained with a ski stop device according to claim 1. Other characteristics
of the ski stop device of the present invention are set down in the dependent claims.

with the skis attached to his/her feet.
[0031] With reference to the tables of drawings, reference numeral (D) denotes the ski stop
device provided by the present invention, in its entirety.
[0032] The stop device (D) comprises a fixing element (1) to the ski which is conformed
and predisposed to be fixed to a ski in a forward position with respect to a heel-piece
(T) suitable for hooking the rear part (PS) of a ski boot when the rear part of the
ski boot is lowered towards the ski.
[0033] In the appended figures the ski is not illustrated, while in figures 3 and 7 the
fixing element (1) of the stop device (D) can be seen, predisposed forward of a heel-piece
(T) for hooking a rear part (PS) of a ski boot (ski boot not illustrated in its entirety
but only the rear part thereof).
[0034] The stop device (D) further comprises a braking element (2) having a shape that is
such as to comprise a fork-shaped first part (21) conformed substantially as a fork
having a pair of arms (22, 23) distanced from one another by a distance that is greater
than the width of the ski and a second part (24) comprising a pair of prongs (25,
26) arranged substantially parallel to one another at a prefixed reciprocal distance.
[0035] The braking element (2) is hinged to the fixing element (1) at a third part (27)
that is intermediate between the first part (21) and the second part (24) (see for
example figure 6) so as to be oscillating about a hinge axis that is transversal to
the fixing element (1) and thus transversal to the ski.
[0036] The braking element (1) is preferably a single body, with the two arms (22, 23) of
the fork in a single body with the pair of prongs (25, 26), for example, in particular,
the braking element (2) is formed by a metal rod appropriately bent and conformed
so as to have, on the one side, the fork with the pair of arms and, on the other side
the pair of prongs, and an intermediate central part between the arms and the prongs
which is coupled to the fixing element according to a transversal axis.
[0037] The stop device can also comprise, for example, a sort of plate (8) which is coupled
to the pair of prongs (25, 26), to form an abutment for the sole of the rear part
(PS) of the ski boot.
[0038] In this way the braking element (2) can assume at least two distinct configurations
with respect to the fixing element (1), and thus with respect to the ski:
an operating configuration (O) in which the arms (22, 23) of the fork are arranged
in a lowered position with respect to the fixing element (1) and thus in a lowered
position with respect to the ski and arranged at the sides of the ski, with the aim
of being able to at least partially penetrate into the snow and
thus provide a friction action for braking the ski, and with the pair of prongs (25,
26) raised with respect to the fixing element (1) and therefore raised with respect
to the ski (see for example figures from 1 to 6, and 6A),
a non-operating configuration (I) in which the arms (22, 23) of the fork are raised
with respect to the ski in order to enable a sliding of the ski on the snow, and with
the pair of prongs (25, 26) lowered towards the fixing element (1) and therefore lowered
towards the ski (see for example figures from 7 to 11, 11A).
[0039] More in particular, the fixing element (1) is conformed in such a way as to comprise
a pair of recesses (31, 32) which are positioned and conformed for receiving internally
thereof the pair of prongs (25, 26) so as to maintain the braking element (2) in the
operating configuration (O), the pair of prongs (25, 26) being raised with respect
to the ski and the arms (22, 23) of the fork being arranged at the sides of the ski
and in a lowered position with respect to the ski (see for example figures 4 and 5).
[0040] Further, the fixing element (1) is also conformed in such a way as to comprise a
pair of fixed guide walls (41, 42) arranged and conformed in such a way as to guide
the pair of prongs (25, 26) towards the ski and force them to near one another when
the prongs (25, 26) are pushed out of the recesses (31, 32) and pushed towards the
ski as a consequence of the lowering of the rear part (PS) of the ski boot towards
the ski for hooking thereof with the heel-piece (T), with a consequent raising of
the arms (22, 23) of the fork and positioning of the braking element (2) in the non-operating
configuration (I) (see for example figures 5, 10 and 11).
[0041] The prongs elastically deform to near one another, sliding along the fixed guide
walls towards the ski by a pushing action towards the ski, exerted thereon by the
ski boot.
[0042] In this way, as soon as the downwards pushing action exerted by the ski boot terminates,
either because the skier has unhooked the ski boot from the ski, or consequently to
a safety release following a fall, the prongs immediately tend to reacquire the initial
configuration thereof, and therefore return to the prefixed reciprocal distance thereof,
rising up the fixed walls up to repositioning in the recesses, returning the arms
of the fork into the lowered position with respect to the ski and thus the braking
element into the operating configuration (O).
[0043] The particularities of the stop device (D) of the present invention consist in the
fact that the fixing element (1) is also conformed so as to comprise a pair of cavities
(51, 52), inferiorly of the pair of fixed walls (41, 42) (visible for example in detail
in figures 6A, 10, 11A, 13, 14, 15A e 15B), and in that it comprises means for keeping
closed and for opening the cavities (51, 52).
[0044] In particular, the means (M) for keeping closed and for opening the cavities (51,
52) are predisposed and conformed in such a way as to be arranged with respect to
the fixing element (1) in two distinct configurations:
a first configuration (M1) in which the means (M) are arranged in such a way as to
keep the cavities (51, 52) closed and in such a way as to form, with the fixed walls
(41, 42), a continuous guide for the prongs (25, 26) towards the ski, so that the
prongs (25, 26) are guided and forced to near one another when the prongs (25, 26)
are pushed out of the recesses (31, 32) and pushed towards the ski as a consequence
of the lowering of the rear part (PS) of the ski boot towards the ski for hooking
thereof with the heel-piece (T), with a consequent raising of the arms (22, 23) of
the fork and positioning of the braking element (2) in the non-operating configuration
(I), and in such a way as to enable the prongs (25, 26) to be able to return to the
prefixed reciprocal distance thereof, and thus lift in order to be re-positioned in
the recesses (31, 32), with a lowering of the pair of arms (22, 23) of the fork and
a re-positioning of the braking element (2) in the operating configuration (O), as
a consequence of a raising of the rear part (PS) of the ski boot from the ski following
the unhooking of the heel-piece (T) (see for example figures 4, 5, 6A, 10, 11A);
and a second configuration (M2) in which the means (M) are arranged in such a way
as to open the cavities (51, 52) so that the prongs (25, 26), when pushed out of the
recesses (31, 32) and pushed towards the ski with a consequent raising of the arms
(22, 23) of the fork with respect to the ski, and once having passed beyond the fixed
walls (41, 42), are facing the cavities (51, 52) so that they can return to the prefixed
reciprocal distance thereof and insert into the cavities (51, 52) and thus be kept
inside the cavities (51, 52) in a lowered position towards the ski, so that the arms
(22, 23) of the fork are kept in a raised position (P) with respect to the ski and
the braking element (2) is kept in the non-operating configuration (I), in order to
enable the skier to undertake ascending routes while wearing the skis and with the
rear part (PS) of the ski boot unhooked from the heel-piece (T) (see for example figures
12, 13, 14, 15A and 15B).
[0045] The means (M) for keeping closed and for opening the cavities (51, 52) are usually
maintained in the first configuration (M1), in which they close the cavities (51,
52) so that the stop device (D) can be normally used, i.e. constantly active, with
the braking element in the operating configuration, and, when the skier lowers the
ski boot to hook the rear part to the heel-piece, can be brought into the non-operating
configuration.
[0046] With the means (M) for keeping closed and for opening the cavities (51, 52) in the
first configuration (M1), for closing the cavities (51, 52), should the skier unhook
the ski boot from the heel-piece to remove the skis, or in a case of and automatic
unhooking in consequence of a possible fall, the braking element can return autonomously
and without problems into the operating configuration to reactivate the stop device,
in the above-described ways.
[0047] Instead, each time the skier intends to cover uphill stretches with the skis at his
or her feet, the stop device can be deactivated in a simple and rapid way by predisposing
the means (M) for keeping closed and for opening the cavities in the second configuration
(M2) with the cavities (51, 52) open.
[0048] Following this, by pushing the prongs (25, 26) downwards (or pushing the plate (8)
downwards), i.e. towards the ski, the skier, for example using the ski stick, or even
by hand, can force the prongs (25, 26) to exit the recesses (31, 32); and by pushing
the prongs (25, 26) even further downwards, the prongs (25, 26) will be forced to
near one another by sliding along the fixed walls (41, 42), with a contemporaneous
raising of the arms (22, 23) of the fork into a raised position from the ski.
[0049] As soon as the prongs (25, 26) have passed beyond the fixed walls (41, 42), they
will reach the open cavities (51, 52) and will tend to return to the prefixed reciprocal
distance, inserting in the cavities (51, 52).
[0050] Once inserted in the cavities (51, 52), the prongs (25, 26) will not be able to freely
and spontaneously rise towards the recesses (31, 32) and thus they will be maintained
in a lowered position towards the ski, with the consequent maintaining thereof in
a raised position with respect to the ski of the arms (22, 23) of the fork, and thus
with the consequent maintaining of the braking element (2) in the non-operating configuration
(I).
[0051] Therefore, the skier can freely maintain the rear part of the ski boot unhooked from
the heel-piece and can cover uphill stretches with the skis fastened to the feet with
no problems between the ski boot and the ski, as the stop element will constantly
and in all cases be maintained in a deactivated status.
[0052] Thus, owing to the presence of the cavities (51, 52) which can be kept open by positioning
the means (M) for keeping closed and for opening the cavities (51, 52) in the second
configuration (M2), the stop device (D) can be easily and rapidly deactivated, i.e.
the braking element placed in the non-operating configuration (I), without any need
to have recourse, as in the prior-art cases, to the use of external locking organs,
such as levers or plates, or to the rotation of the heel-piece.
[0053] There will therefore be no unnecessary or useless accoutrements, nor the awkward
presence of rises on the ski, so the skier can newly hook the rear part of the ski
boot to the heel-piece at any time.
[0054] To return the stop device to the normal functioning thereof, it will be sufficient
to press together, for example by squeezing with a hand, the pairs of arms (22, 23)
of the fork together to near them to one another so as consequently to force the prongs
(25, 26) to near one another, and thus exit the cavities and therefore, possibly,
to push the arms (22, 23) of the fork downwards, then to release them.
[0055] In this way, the prongs will return to the mutual prefixed distance by rising along
the fixed guide walls (41, 42) up to reinserting in the relative recesses (31, 32).
[0056] Following this it will be sufficient to reposition the means (M) for keeping closed
and for opening the cavities in the first closed configuration (M1) of the cavities
(51, 52).
[0057] Other advantageous characteristics of the ski stop device (D) of the present invention
are set down in the following.
[0058] In the preferred embodiment illustrated in the appended figures, the means (M) for
keeping closed and for opening the cavities (51, 52) can be conceived in such a way
as to comprise a pair of movable walls (61, 62) which are predisposed so as to be
movable with respect to the fixing element (1) in such a way as to be positionable
with respect to the pair of fixed walls (41, 42) in at least two positions:
an aligned position (A) with the fixed walls (41, 42), wherein the movable walls (61,
62) are aligned to the fixed walls (41, 42) so as to occlude the cavities (51, 52)
and so as to form, with the fixed walls (41, 42), a continuous guide for the prongs
(25, 26) towards the ski, so that the prongs (25, 26) are guided and forced to near
one another when the prongs (25, 26) are pushed out of the recesses (31, 32) and pushed
towards the ski as a consequence of the lowering of the rear part (PS) of the ski
boot towards the ski for hooking thereof with the heel-piece (T) and in such a way
as to enable the prongs (25, 26) to be able to return to the prefixed reciprocal distance
thereof, and thus reposition in the recesses (31, 32), with a lowering of the pair
of arms (22, 23) of the fork and a re-positioning of the braking element (2) in the
operating configuration (O), as a consequence of a raising of the rear part (PS) of
the ski boot from the ski following the unhooking of the heel-piece (T) (see in detail
figures 4, 5, 6A, 10, 11A);
and a de-aligned position (B) with the fixed walls (41, 42), in which the movable
walls (61,62) are de-aligned with respect to the fixed walls (41, 42) so as to open
the cavities (51, 52) so that the prongs (25, 26), when pushed out of the recesses
(31, 32) and towards the ski with a consequent raising of the arms (22, 23) of the
fork with respect to the ski, and once having passed beyond the fixed walls (41, 42),
are facing the cavities (51, 52) so that they can return to the prefixed reciprocal
distance thereof and insert into the cavities (51, 52) and thus be kept inside the
cavities (51, 52) in a lowered position towards the ski, so that the arms (22, 23)
of the fork are kept in a raised position (P) with respect to the ski and the braking
element (2) is kept in the non-operating configuration (I), in order to enable the
skier to undertake ascending routes while wearing the skis and with the rear part
(PS) of the ski boot unhooked from the heel-piece (T) (see in detail figures 12, 13,
14, 15A, 15B).
[0059] To keep the cavities (51, 52) closed, or to open the cavities (51, 52) by displacing
the movable walls (61, 62), in the aligned position (A) with the fixed walls (41,
42) or in the de-aligned position (B) with the fixed walls (41, 42), the stop device
(D) can advantageously comprise, in the preferred embodiments illustrated in the appended
figures, a slide (6) which is coupled to the fixing element (1) in such a way as to
be translatable transversally to the fixing element (1), and thus transversally to
the ski, the pair of movable walls (61, 62) being predisposed on the, and borne by,
the slide (6).
[0060] The slide (6) is translatable with respect to the fixing element (1) at least between
two lateral positions, a first lateral position (L1) in which the movable walls (61,
62) are positioned in the aligned position (A) with the fixed walls (41, 42) (see
figures 4, 5, 6A, 10, 11A) and a second lateral position (L2) in which the movable
walls (61, 62) are positioned in the de-aligned position (B) with respect to the fixed
walls (41, 42) (see figures 12, 13, 14, 15A).
[0061] In this way, it will be very easy for the skier to close or open the cavities simply
by translating the slide (6) with respect to the fixing element (1) from the first
lateral position (L1) to the second lateral position (L2) and vice versa, according
to the embodiment illustrated in figures from 1 to 6 and from 7 to 11, and from 12
to 14.
[0062] Figures 6A, 11A, 15A and 15B, instead, illustrate, as mentioned in the foregoing,
a possible interesting embodiment of the stop device (D) of the invention.
[0063] In this preferred embodiment, the means (M) for keeping closed and for opening the
cavities (51, 52) can comprise a spring (9) which is predisposed in a housing (90)
realised in the fixing element (1).
[0064] In particular, the housing (90) is realised in the fixing element (1) and the spring
(9) is predisposed in the housing (90) in such a way that the spring (9) is in contact
with the slide (6) and maintains the slide (6) in the first lateral position (L1),
so that the movable walls (61, 62) are normally maintained in the aligned position
(A) thereof with the fixed guide walls (41, 42) (see for example figures 6A and 11A).
[0065] In this way, the stop device (D) can be normally used, i.e. be constantly active,
with the braking element in the operating configuration (figure 6A), and, when the
skier (2) lowers the ski boot to hook the rear part to the heel-piece, can be brought
into the non-operating configuration (I) (figure 11A).
[0066] With the means (M) for keeping closed and for opening the cavities (51, 52) in the
first configuration (M1), with the cavities (51, 52) closed, i.e. with the spring
(9) pushing on the slide (6) and maintaining the slide (6) in the first lateral position
(L1), if the skier were to unhook the ski boot from the heel-piece to remove the ski,
or if there is an automatic unhooking consequent to a fall, the braking element (2)
can return autonomously and without problems into the operating configuration to reactivate
the stop device, in the above-described ways.
[0067] Instead, each time the skier wishes to cover uphill stretches, while keeping the
skis on his/her feet, he/she will be able to deactivate the stop device (D) simply
by pushing on the slide (6) in order to shift it into the second lateral position
(L2), compressing the spring (9) and bringing the means (M) for keeping closed and
for opening the cavities into the second configuration (M2), for opening the cavities
(51, 52) (see figure 15A).
[0068] Thus, at the same time, the skier, by pushing the prongs (25, 26) downwards (or by
pushing the plate (8) downwards), i.e. towards the ski, for example by using the ski
sticks, or even a hand, can force the prongs (25, 26) to exit the recesses (31, 32)
and by pushing downwards even more, the prongs (25, 26) will be forced to near one
another by sliding along the fixed walls (41, 42), with a contemporaneous raising
of the arms (22, 23) of the fork into a raised position from the ski.
[0069] As soon as the prongs (25, 26) have passed beyond the fixed walls (41, 42), they
will reach the open cavities (51, 52) and will tend to return to the prefixed reciprocal
distance, inserting in the cavities (51, 52).
[0070] Once the prongs (25, 26) have inserted in the cavities (51, 52), the skier can release
the slide (6): the spring (9) will tend to push the slide (6) to return it towards
the first lateral position (L1), but the presence of the prongs (25, 26) in the cavities
(51, 52) will prevent translation thereof (see figure 15B).
[0071] In this way, the prongs (25, 26) will be maintained in the cavities (51, 52) and
will not freely and spontaneously rise towards the recesses (31, 32) and thus will
be maintained in a lowered position towards the ski, with the consequent maintaining
in a raised position with respect to the ski of the arms (22, 23) of the fork, and
thus with the consequent maintaining of the braking element (2) in the non-operating
configuration.
[0072] Therefore, the skier can freely maintain the rear part of the ski boot unhooked from
the heel-piece and can cover uphill stretches with the skis fastened to the feet with
no problems between the ski boot and the ski, as the stop element will constantly
and in all cases be maintained in a deactivated status.
[0073] In this particular embodiment, should the skier wish to cover downhill stretches,
and therefore hook the ski boot to the heel-piece, the stop device can be reactivated,
and thus returned to the normal functioning thereof, automatically due to the presence
of the spring (9).
[0074] In fact, it will be sufficient for the skier to press the pairs of arms (22, 23)
of the fork together to near them to one another so as consequently to force the prongs
(25, 26) to near one another, against the pushing action of the spring (9), and thus
exit the cavities (51, 52).
[0075] In this way, the prongs (25, 26) will return to the mutual prefixed distance by rising
along the fixed guide walls (41, 42) up to reinserting in the relative recesses (31,
32) and at the same time the spring (9) will push on the slide (6) to as to return
the slide (6) automatically into the first lateral position (L1) of alignment (A)
of the movable walls (61, 62) with the fixed walls (41, 42) (figures 6A e 11A).
[0076] The fixed walls (41, 42) can preferably be realised and conformed in such a way as
to have a mutually converging conformation towards the ski or have a conformation
that is such as to be mutually parallel and at a reciprocal distance that is smaller
than the prefixed reciprocal distance of the prongs (25, 26) of the braking element
(2).
[0077] In turn, the movable walls (61, 62) can be realised and conformed in such a way as
to have a mutually converging conformation towards the ski, with the same inclination
as the fixed walls (41, 42) or with a different inclination but however with a reciprocal
distance that is smaller than the prefixed reciprocal distance of the prongs (25,
26) of the braking element (2).
[0078] Alternatively, the movable walls can be realised and conformed such as to have a
conformation such as to be parallel to one another and at a reciprocal distance that
is smaller than the prefixed reciprocal distance of the prongs (25, 26) of the braking
element (2).
1. A ski stop device (D), comprising:
a fixing element (1) to the ski, for fixing to a ski in a forward position with respect
to a heel-piece (T) suitable for hooking the rear part (PS) of a ski boot when the
rear part of the ski boot is lowered towards the ski;
a braking element (2) having a shape comprising a fork-shaped first part (21) having
a pair of arms (22, 23) distanced from one another by a distance that is greater than
the width of the ski and a second part (24) comprising a pair of prongs (25, 26) arranged
substantially parallel to one another at a prefixed reciprocal distance, the braking
element (2) being hinged to the fixing element (1) at a third part (27) that is intermediate
between the first part (21) and the second part (24) and being oscillating about a
hinge axis that is transversal to the fixing element (1) and thus transversal to the
ski, in such a way that the braking element (2) can assume at least two distinct configurations
with respect to the fixing element (1), and therefore with respect to the ski:
an operating configuration (O) in which the arms (22, 23) of the fork are arranged
in a lowered position with respect to the fixing element (1) and thus in a lowered
position with respect to the ski and arranged at the sides of the ski, with the aim
of being able to at least partially penetrate into the snow and thus provide a friction
action for braking the ski, and with the pair of prongs (25, 26) raised with respect
to the fixing element (1) and therefore raised with respect to the ski,
a non-operating configuration (I) in which the arms (22, 23) of the fork are raised
with respect to the ski in order to enable a sliding of the ski on the snow, and with
the pair of prongs (25, 26) lowered towards the fixing element and therefore lowered
towards the ski;
the fixing element (1) being conformed to comprise:
a pair of recesses (31, 32) which are positioned and conformed for receiving internally
thereof the pair of prongs (25, 26) to maintain the braking element (2) in the operating
configuration (O), the pair of prongs (25, 26) being raised with respect to the ski
and the arms (22, 23) of the fork being arranged at the sides of the ski and in a
lowered position with respect to the ski,
and a pair of fixed guide walls (41, 42) arranged and conformed to guide the pair
of prongs (25, 26) towards the ski and force them to near one another when the prongs
(25, 26) are pushed out of the recesses (31, 32) and pushed towards the ski as a consequence
of the lowering of the rear part (PS) of the ski boot towards the ski for hooking
thereof with the heel-piece (T), with a consequent raising of the arms (22, 23) of
the fork and positioning of the braking element (2) in the non-operating configuration
(I);
and being characterised in that the fixing element (1) is conformed to comprise a pair of cavities (51, 52), inferiorly
of the pair of fixed walls (41, 42), and in that it comprises means (M) for keeping closed and for opening the cavities, (51, 52),
the means (M) for keeping closed and for opening the cavities, (51, 52) being predisposed
and conformed to be arrangeable with respect to the fixing element (1) in two distinct
configurations:
a first configuration (M1) in which the means (M) are arranged to keep the cavities
(51,52) closed and to form, with the fixed walls (41, 42), a continuous guide for
the prongs (25, 26) towards the ski, so that the prongs (25, 26) are guided and forced
to near one another when the prongs (25, 26) are pushed out of the recesses (31, 32)
and pushed towards the ski as a consequence of the lowering of the rear part (PS)
of the ski boot towards the ski for hooking thereof with the heel-piece (T), with
a consequent raising of the arms (22, 23) of the fork and positioning of the braking
member (2) in the non-operating configuration (I), and in such a way as to enable
the prongs (25, 26) to be able to return to the prefixed reciprocal distance thereof,
and thus lift in order to reposition in the recesses (31, 32), with a lowering of
the pair of arms (22, 23) of the fork and a re-positioning of the braking element
(2) in the operating configuration (O), as a consequence of a raising of the rear
part (PS) of the ski boot from the ski following the unhooking of the heel-piece (T);
and a second configuration (M2) in which the means (M) are arranged to open the cavities
(51, 52) so that the prongs (25, 26), when pushed out of the recesses (31, 32) and
towards the ski with a consequent raising of the arms (22, 23) of the fork with respect
to the ski, and once having passed beyond the fixed walls (41, 42), are facing the
cavities (51, 52) so that they can return to the prefixed reciprocal distance thereof
and insert into the cavities (51, 52) and thus be kept inside the cavities (51, 52)
in a lowered position towards the ski, so that the arms (22, 23) of the fork are kept
in a raised position (P) with respect to the ski and the braking element (2) is kept
in the non-operating configuration (I), in order to enable the skier to undertake
ascending routes while wearing the skis and with the rear part of the ski boot unhooked
from the heel-piece (T).

62) are aligned to the fixed walls (41, 42) so as to occlude the cavities (51, 52)
and so as to form, with the fixed walls (41, 42), a continuous guide for the prongs
(25, 26) towards the ski, so that the prongs (25, 26) are guided and forced to near
one another when the prongs (25, 26) are pushed out of the recesses (31, 32) and pushed
towards the ski as a consequence of the lowering of the rear part (PS) of the ski
boot towards the ski for hooking thereof with the heel-piece (T) and in such a way
as to enable the prongs (25, 26) to be able to return to the prefixed reciprocal distance
thereof, and thus reposition in the recesses (31, 32), with a lowering of the pair
of arms (22, 23) of the fork and a re-positioning of the braking element (2) in the

and a de-aligned position (B) with the fixed walls (41, 42), in which the movable
walls (61,62) are de-aligned with respect to the fixed walls (41, 42) so as to open

(31, 32) and towards the ski with a consequent raising of the arms (22, 23) of the
fork with respect to the ski, and once having passed beyond the fixed walls (41, 42),
are facing the cavities (51, 52) so that they can return to the prefixed reciprocal
distance thereof and insert into the cavities (51, 52) and thus be kept inside the
cavities (51, 52) in a lowered position towards the ski, so that the arms (22, 23)
of the fork are kept in a raised position (P) with respect to the ski and the braking
element (2) is kept in the non-operating configuration (I), in order to enable the
