[0001] The invention relates to an apparatus for locking a pair of skis in a reciprocal
position in such a way as to prevent, or at least hinder, the use of that pair of
skis by unauthorised persons.
[0002] Prior art includes ski closure straps, for example elastic straps, provided at their
ends with coupling elements that engage with each other, allowing the skis to be kept
stationary relative to each other when the straps are wrapped around the front and
rear ends of a pair of skis, after the bottom faces of the skis (that is the faces
that do not carry the bindings) have been placed one against the other. These straps
are used to hold the skis steady and to facilitate transport.
[0003] Said closure straps, when fitted on a pair of skis left in a public place, for example
during a break, are unable to prevent anyone from freeing the skis in order to steal
them from their legitimate owner; this is a particularly frequent occurrence at ski
lodges, where skis are left temporarily, for example by inserting one end in the snow
or mounting them on racks.
[0004] The aim of the present invention is to provide an apparatus capable of preventing,
or at least discouraging, theft of a pair of skis by a third party.
[0005] According to the invention, there is provided apparatus comprising a closure body
capable of closing a pair of skis one against the other, said closure body being provided
at its ends with coupling means suitable for placing said body in a stably closed
condition, characterised in that said closure body is rigid at least in said closed
condition and in that said body also has locking means suitable for locking said coupling
means in, or releasing it from, said closed condition.
[0006] Thus, the owner of the skis has a system for locking and unlocking the coupling means
and can therefore leave the skis on the snow after locking them together stably to
discourage theft: although a third party could remove them without freeing them, and
transport them for example on his shoulders, this would in any case arouse the suspicion
of anyone witnessing the event. Obviously in order for a third party not to be able
simply to remove the closure apparatus by sliding it along the skis, the apparatus
must be fitted in an appropriate position between the front end of the skis and the
boot bindings, or between a pair of front elements and a pair of rear elements of
said bindings.
[0007] In a particularly advantageous embodiment, the locking means comprise a numerical
combination lock device; this way the owner can lock and unlock the coupling means
without using keys or other elements separate from the ski closure apparatus which
could be lost or stolen.
[0008] In another particularly advantageous embodiment, an anchor means to secure the ski
closure apparatus during use to a stationary element such as a tree or a post is connected
to the closure body; this represents a further obstacle to theft of the skis.
[0009] The invention can be better understood and carried out with reference to the attached
drawings, which illustrate, purely by way of example, some forms of construction.

[0016] Figure 10 is a partially interrupted cross-sectional top view of Figure 9.
[0017] Figure 11 is the cross-sectional view XI-XI of Figure 10.
[0018] Figures 12 and 13 are analogous cross-sectional views to that of Figure 11, illustrating
operation of said further embodiment of the invention.
[0019] With reference to Figures from 1 to 4, an apparatus 1 comprises a closure body 3
suitable for closing together a pair of skis 2 after the lower faces of said skis
have been placed one against the other; the closure body 3 has a first jaw 4 provided
at a first end 4a with a closure element 5 with toothing, constituting part of coupling
means 17 which comprises an opening 6 obtained in a corresponding first end 7a, corresponding
to the first end 4a, of a second jaw 7, and in which the closure element 5 can be
inserted. The second jaw 7 includes numerical combination locking means 8 suitable
for locking or unlocking the closure element 5, by respectively engaging or disengaging
a tooth 33 on its toothing by way of a bolt 18 which faces the opening 6. The bolt
18 is actuated by a numerical combination system of known type provided with three
drum combination elements 19 for selecting a combination of characters, for example
numbers, and a button 20 which causes the bolt 18 to withdraw from the opening 6 when
a predetermined combination of numbers has been selected. With a second end 4b of
the first jaw 4 there is coupled a sliding element 9, which can slide in a cavity
10 obtained in a corresponding second end 7b, corresponding to the second end 4b,
of the second jaw 7, allowing the opening 6 to be freed of the closure element 5 and
allowing the distance between the first jaw 4 and the second jaw 7 to be varied in
order to allow the apparatus 1 to be used with skis 2 varying in thickness within
an appropriate interval. Said sliding element 9 is provided, at its free end 9a not
coupled to the first jaw 4, with a pin 11 which protrudes transversally relative to
the longitudinal sliding direction of element 9 in cavity 10; when the first jaw 4
and the second jaw 7 are moved towards or away from each other, pin 11 slides along
a longitudinal guide channel 12 obtained on one wall of the cavity 10 and parallel
to the longitudinal sliding direction of element 9 and ending near the corresponding
second end 7b. This prevents the sliding element 9 from coming completely out of cavity
10, hence ensuring that the first jaw 4 and the second jaw 7 remain secured together
at all times. At the end of the longitudinal guide channel 12 near the corresponding
second end 7b, there is located a groove 13 also obtained on the wall of the cavity
10 and lying in an orthogonal plane relative to the longitudinal sliding direction
of element 9, pin 11 being able to slide along the groove 13 when the apparatus 1
is in its maximum open position, and the first jaw 4 and the second jaw 7 being able
to rotate relative to each other around an axis defined by the longitudinal sliding
direction of element 9 inside the cavity 10. Anchoring means 25 for securing the apparatus
1 to a fixed element such as a tree or a post during use are associated to the first
jaw 4. The anchoring means 25 comprise a winding roller 14 incorporated in the first
jaw 4 near the first end 4a; on said roller 14 there unwinds or winds a strap 15,
which issues from the first jaw 4 and is provided at its free end 15a with a loop
16 suitable for being engaged by the closure element 5 before being inserted in opening
6. This way it is possible to keep the apparatus 1 tied to a tree or a post by way
of strap 15 when the skis 2 are locked together. The winding roller 14 has a spring
that permits automatic winding of the strap 15 when the ring 16 has been disengaged.
[0020] Figure 5 shows a second embodiment of the apparatus according to the invention. This
second embodiment differs from the embodiment described above by the presence of a
rotation pin 21 which permits rotational coupling of the sliding element 9 with the
first jaw 4. This introduces an additional degree of freedom into the apparatus 1,
the first jaw 4 and the second jaw 7 being additionally able to rotate with respect
to an axis orthogonal to the plane of the cross-sectional view shown in the Figure
when the apparatus 1 is not in the closed condition.
[0021] In a third embodiment of the apparatus according to the invention, shown in Figure
6, the coupling means 17 includes a seat 22 obtained in the locking means 8 and capable
of receiving one of a plurality of retaining elements 23 located on one side 24 of
the closure element 5, oriented towards the locking means 8. The closure element 5
is hinged to the first jaw 4, at the first end 4a thereof. On closing the apparatus
1, the element 5 is rotated relative to the first jaw 4 in such a way that a retaining
element 23 is received by the seat 22; the bolt 18 of the locking means 8 thereby
engages the retaining element 23, freeing it only after the predetermined numerical
combination has been selected. Furthermore, in this embodiment the anchoring means
25 is located at the second end 4b of the first jaw 4.
[0022] A fourth embodiment of the apparatus according to the invention, shown in Figure
7, has a similar coupling means 17 to the one shown in Figure 6; however, the closure
element 5 is not hinged to the first jaw 4 at its first end 4a. To free the retaining
element 23 of the closure element 5 from the seat 22, after releasing the bolt 18,
the first jaw 4, integral with closure element 5, must be rotated around rotation
pin 21 (similar to the one shown in Figure 5) located at the second end 4b of jaw
4.
[0023] In a fifth embodiment of the apparatus according to the invention, shown in Figure
8, the second jaw 7 and the closure element 5 are rotationally coupled by way of a
rotation pin element 26 which allows closure element 5 either to rotate away from
the first jaw 4, thereby allowing the closure body 3 to open for the purpose of freeing
or introducing the skis 2, or to rotate towards the first jaw 4, thereby allowing
the closure body 3 to close after the skis 2 have been introduced. The first jaw 4
is provided, at its first end 4a, with a male coupling element 27 capable of coupling,
when the closure body 3 is in the closed position, with one of a plurality of female
coupling elements 28, obtained in one side 29 of the closure element 5, oriented towards
the first jaw 4. At the position of the locking means 8, the closure element 5 has
a protuberance 30, which projects orthogonally with respect to side 29 and is received,
when the closure body 3 is in the closed condition, by a corresponding recess 31 in
the locking means 8. In these conditions, the bolt 18 engages the protuberance 30
on one side 32 thereof; if the bolt 18 is released, the recess 31 can be freed of
the protuberance 30 by making the closure element 5, with which protuberance 30 is
integral, rotate on the rotation pin element 26 away from the first jaw 4.
[0024] The Figures from 9 to 12 show a sixth embodiment of the apparatus according to the
invention, in which one of the jaws 4, 7, for example the first jaw 4, has a portion
33 with a reduced cross-section, capable of being inserted in an opening 34 obtained
in a plate means 35 to which there is fixed, for example near one side 37, one end
of the strap 15, opposite the free end 15a. The opening 34 in the plate 35 has at
least one seat 39 capable of being coupled to said portion 33 so as to prevent plate
35 from rotating relative to the first jaw 4.
[0025] The plate 35 is coupled to said portion 33 of the jaw 4 during construction of said
jaw so that it cannot be separated from jaw 4 but can slide and rotate relative to
it.
[0026] When the apparatus 1 is in the closed condition without the skis 2 inserted in it,
the plate 35 is in the position shown in Figure 11, with the portion 33 of the jaw
4 inserted in the seat 39, with the side 37 directed towards the inside of the apparatus
and the other side 38, opposite side 37, directed towards the outside of the apparatus
1 and positioned in such a way that it does not protrude from the profile of the apparatus.
In this situation, the strap 15 can be positioned inside the apparatus 1, between
the jaws 4 and 7.
[0027] In order to insert a pair of skis 2 in the apparatus 1, after placing the apparatus
1 in the open position, the plate 35 is pushed outwards, that is to the left with
reference to figure 10, freeing portion 33 of jaw 4 from the seat 39, the plate 35
is rotated by 180° and moved further towards the outside of apparatus 1 until the
portion 33 is reinserted in seat 39. In this situation the plate 35 is positioned
in such a way that its side 38 does not protrude towards the inside of the apparatus
1, so as not to damage the skis 2 inserted inside it. After placing the apparatus
1 in the closed position with the skis 2 locked inside it, apparatus 1 can be secured
to a post, a tree or another securing means by way of strap 15.
