Description
- This application claims the benefit of Italian Patent Application No. 102015000043676, filed Aug. 10, 2015, the disclosure of which is hereby incorporated entirely herein by reference.
- The present invention relates to a ski boot.
- In more detail, the present invention relates to a ski boot for ski-mountaineering and Telemark, use to which the following description will make explicit reference without thereby losing generality.
- As is well known, ski boots for practicing ski-mountaineering and Telemark basically comprise: a rigid shell made of plastic or composite material, which is shaped so as to accommodate the foot of the user, and has the boom part specifically structured so as to be fastened onto the back of downhill ski or similar via a ski-mountaineering or Telemark ski binding device; and a rigid cuff made of plastic or composite material, which is shaped so as to enclose the lower part of the leg of the user from behind, and is hinged to the upper part of the shell so as to be able to rotate around a transversal reference axis, which is substantially perpendicular to the midplane of the boot and is also locally substantially coinciding with the articulation axis of the ankle.
- In more detail, the bottom part of the shell is provided in the front with a tip specifically structured to be able to hook in a rigid and stable, though easily releasable manner to the toe piece of a ski-mountaineering or Telemark ski binding device which, in turn, is structured to firmly hold the tip of the shell on the backside of the ski beneath, with the possibility of freely rotating about a reference axis perpendicular to the midplane of the boot. In this way, the user is able to lift the heel of the ski boot from the backside of the ski as needed, while always and still maintaining the tip of the boot firmly anchored to the ski beneath.
- To guarantee the necessary structural stiffness in the coupling point, in more modern ski-mountaineering and Telemark boots, the rigid shell is additionally provided with a transversal metal insert which is completely embedded in the plastic material and extends inside the tip of the shell perpendicular to the midplane of the boot. Moreover, the transversal insert is structured so as to surface on the outside of the shell at the two lateral sides of the tip, in symmetrical position on opposite sides of the midplane of the boot, so the two ends of the insert can be clamped firmly and in an axially rotatable manner by the locking clamp of the toe piece of the ski-mountaineering or Telemark ski binding device.
- Aim of the present invention is to realize a transversal insert allowing the tip of the shell to be clamped in two distinct points along the lateral sides of the tip, and which is furthermore compatible with a great variety of ski-mountaineering and Telemark ski binding devices.
- In compliance with these aims, according to the present invention there is provided a ski boot as defined in
claim 1 and preferably, though not necessarily, in any one of the depending claims. - The present invention will now be described with reference to the accompanying drawings, which show a non-limitative embodiment thereof, in which:

FIG. 2 , in the example shownrigid casing 6 is preferably provided with a substantially U-shaped, projecting ledge orshelf 11 that cantilevered protrudes from the front part ofcasing 6 while remaining locally substantially coplanar to thebottom wall 8 ofcasing 6, and surrounds the tarso-phalangeal region of the sole of the foot so as to form thetip 4 ofshell 2; and the two conjugated coupling areas are located along the twolateral sides 10 of the projectingshelf 11. - In other words, the
transversal insert 9 is embedded inside thebottom wall 8 at the projectingshelf 11, so as to be able to emerge/surface outside of therigid casing 6 at the twolateral sides 10 of projectingshelf 11, in substantially symmetrical position on opposite sides of the midplane of the boot. - With reference to
FIG. 1 , preferably therigid casing 6 is superiorly provided with a flexibletransversal band 12 which is structured to elastically deform, and extends from the inner side to the outer side of theshell 2 more or less perpendicularly to the midplane of the boot, while passing over the instep of the foot substantially straddling the metatarsus, so as to allow the inside of theshell 2 to bend locally in order to meet the bending of the foot. - In the example shown, in particular, the
rigid casing 6 is preferably made of PEBAX (polyether block amide), but could also be made of Nylon (polyamide) or other similar plastic polymers. - Alternatively, the
rigid casing 6 could also be made of a composite material, preferably formed by one or more overlapping layers of carbon fibres and/or glass fibres and/or aramid fibres, conveniently interwoven with and/or overlapping each other and embedded in a matrix of epoxy, phenolic or polyester resin, preferably of the thermosetting variant. - The front sole 7, on the other hand, preferably has a treaded profile and is preferably made of vulcanized rubber of other elastomeric material with high friction coefficient, and is preferably unmovably fixed to the
bottom wall 8 ofrigid casing 6 by gluing. - With reference to
FIGS. 1, 2 and 3 , thetransversal stiffening insert 9 in turn comprises: a preferably substantially platelike,central portion 13 which extends inside thebottom wall 8 ofcasing 6, straddling and substantially perpendicular to the midplane of the boot, so as to be locally substantially coplanar to thebottom wall 8 of thecasing 6, and thus locally substantially parallel to the underlying sole 7; and two mainlateral appendages 14 which extend cantilevered from the plate-likecentral portion 13, on opposite sides of the vertical midplane of the boot, and are structured so that the respective distal ends emerge/surface outside ofrigid casing 6 on opposite sides of the midplane of the boot, at the twolateral sides 10 oftip 4 ofshell 2, or better of the projectingshelf 11 ofcasing 6, and immediately above the sole 7, while remaining locally substantially coaxial to the transversal axis B, i.e. in substantially symmetrical position on opposite sides of the midplane of the boot. - In other words, the two
lateral appendages 14 oftransversal insert 9 extend cantilevered from the plate-likecentral portion 13, on opposite sides of the latter, so that the distal ends of the twolateral appendages 14 are substantially coaxial to a same reference axis which is substantially perpendicular to the midplane of the plate-likecentral form 13 and, in addition, coincides with the transversal axis B whentransversal insert 9 is embedded in thebottom wall 8 ofcasing 6. - With particular reference to
FIGS. 2 and 3 , the distal ends of the two mainlateral appendages 14 are moreover structured so as to be firmly engaged and clamped in axially rotatable manner by the locking clamp (not shown) of the toe piece of the ski binding device, and thus form the two conjugated coupling areas of thetip 4 ofshell 2. - In other words, the distal end of each
lateral appendage 14 is shaped/structured so as to be engaged in removable and axially rotatable manner about transversal axis B by the locking clamp of the toe piece of the ski binding device. - With reference to
FIGS. 2 and 3 , in the example shown, in particular, the distal end of eachlateral appendage 14 of thetransversal insert 9 is preferably provided with a substantially ogival and/or cylindrical, blind hole orcavity 15 which extends coaxial to transversal axis B towards the inside of theshell 2, i.e. towards the plate-likecentral portion 13, and is preferably dimensioned so as to be engaged in axially rotatable and removable and manner by the distal end of a coupling pin (not shown) of the locking clamp of the toe piece of a ski-mountaineering or Telemark ski binding device of known type. - In more detail, in the example shown, the
blind hole 15 is preferably dimensioned so as to be engaged in axially rotatable and removable manner by the distal end of the coupling pin of the main locking clamp of the toe piece of the Telemark ski binding device which is sold by the Italian company ATK RACE S.R.L. under the name “Newmark”. - Obviously,
blind hole 15 could also be engaged in axially rotatable and removable manner by the distal end of the coupling pin of the locking clamp of the tow piece of a Dynafit-type ski-mountaineering ski binding device or similar, like those described, for example, in European patents EP0199098 and EP1559457 and in international patent application WO2007/010392. - With reference to
FIGS. 1, 2 and 3 , thetransversal stiffening insert 9 moreover comprises two additionallateral appendages 16 which extend cantilevered from thecentral portion 13 on opposite sides of the midplane of the boot, and are structured so that the respective distal ends emerge/surface outside of therigid casing 6 on opposite sides of the midplane of the boot, at the twolateral sides 10 oftip 4 ofshell 2, or better of the projectingshelf 11 ofcasing 6, and immediately above the sole 7, spaced beside the mainlateral appendages 14. - In more detail, the two additional
lateral appendages 16 are preferably structured so that the corresponding distal ends emerge/surface outside of therigid casing 6 at the twolateral sides 10 oftip 4 ofshell 2, or better of the projectingshelf 11 ofcasing 6, in a rearward position with respect to the mainlateral appendages 14, i.e. between the mainlateral appendages 14 and therear heel 5. - Preferably the two additional
lateral appendages 16 are moreover aligned perpendicularly to the midplane of the boot. - In other words, the two additional
lateral appendages 16 oftransversal insert 9 extend cantilevered from the plate-likecentral portion 13, on opposite sides of the same and beside the two mainlateral appendages 14, so that the distal ends of the additionallateral appendages 16 are misaligned/displaced with respect to the axis intersecting the distal ends of the two mainlateral appendages 14, i.e. to transversal axis B, and so that they are preferably aligned to a second reference axis locally parallel and placed beside the transversal axis B. - With reference to
FIG. 2 , preferably these two additionallateral appendages 16 are moreover structured so that the corresponding distal ends emerge/surface outside of therigid casing 6, at the upper edges of the twolateral sides 10 of projectingshelf 11. - The distal ends of the two additional
lateral appendages 16 are therefore located at opposite sides of the tarsophalangeal region of the sole of the foot, preferably in a substantially symmetrical position on opposite sides of the midplane of the boot, and are overall structured so as to be selectively firmly engaged and clamped by the toe piece (not shown) of the ski binding device in a separate and independent manner with respect to the distal ends of the two mainlateral appendages 14. - In more detail, the distal ends of the two additional
lateral appendages 16 are preferably structured so as to be firmly engaged and clamped by the ends of the auxiliary locking clamp of the toe piece of the Telemark ski binding device sold by the Italian company ATK RACE S.R.L. under the name “Newmark”, so that the toe piece (not shown) of the above-mentioned Telemark ski binding device can selectively prevent rotation ofshell 2, or better ofski boot 1, about transversal axis B. - With particular reference to
FIGS. 1 and 2 , the transversalstiffening insert 9 ofshell 2 is thus provided with two first conjugatedcoupling ends 14 that surface outside ofrigid casing 6 along the twolateral sides 10 of thetip 4 ofshell 2, on opposite sides of the midplane of the boot, substantially coaxial to the transversal axis B; and with two second conjugatedcoupling ends 16 that surface outside ofrigid casing 6 along the twolateral sides 10 of thetip 4 ofshell 2, on opposite sides of the midplane of the boot, spaced beside the first conjugatedcoupling ends 14. - The first two conjugated coupling ends 14 and the second two conjugated
coupling ends 16 of thetransversal insert 9 are therefore located at opposite sides of the tarsophalangeal region of the sole of the foot, preferably in pairs aligned with each other, and are intended to be separately engaged and clamped by the toe piece (not shown) of the ski binding device. - In more detail, the first pair of conjugated
coupling ends 14 is structured for being engaged and clamped in axially rotatable manner about transversal axis B, by a first locking clamp (not shown) of the toe piece of the ski binding device. Said first locking clamp (not shown) of the toe piece of the ski binding device is therefore able to firmly hold thetip 4 ofshell 2 on the backside of the ski, while allowing at the same time theshell 2 to freely rotate about transversal axis B. - The second pair of conjugated
coupling ends 16 is spaced beside the first pair of conjugatedcoupling ends 14, or better is misaligned/displaced with respect to transversal axis B, preferably in rearward position with respect to the first pair of conjugatedcoupling ends 14, and is structured for being engaged and clamped by a second locking clamp (not shown) of the toe piece of the ski binding device. Said second locking clamp (not shown) of the toe piece of the ski binding device is therefore able hold thetip 4 ofshell 2 in abutment against the backside of the ski, preventing in this way theshell 2 to freely rotate about transversal axis B. - With reference to
FIG. 1 , on the other hand,cuff 3 is fixed in freely rotating manner to theshell 2, or better to the top part of therigid casing 6, by two lateral connectinghinges 17 that are placed on the inner and outer lateral sides ofshell 2 and ofcuff 3, aligned along rotation axis A, so as to allow thecuff 3 to freely pivot on theshell 2 either forwards or backwards, while always remaining on a reference plane orthogonal to axis A and substantially coinciding with the midplane of the boot. - In addition to the above, the
ski boot 1 preferably additionally comprises aninner liner 18 having a soft and thermal insulating structure, optionally also of thermo-formable type, and which is inserted intoshell 2 and optionally also intocuff 3 preferably, though not necessarily in removable manner, and is shaped so as to accommodate and protect the foot and optionally also the lower part of the leg of the user. - Lastly,
ski boot 1 is moreover provided with a series of manually-operatedlocking devices 19, in the example shown in particular a series traditional lever buckles, which are conveniently distributed onshell 2 and oncuff 3, and are structured so as to be able to selectively close /tighten shell 2 and cuff 3 against the leg of the user, in order to stably immobilize the leg of the user inside theski boot 1, or better inside theinner liner 18; and optionally also with a manually-operated or automaticcuff locking device 20 which is structured so as to be able to selectively link thecuff 3 in a rigid manner to theshell 2, in order to prevent thecuff 3 from freely pivoting about the transversal axis A. - With reference to
FIG. 1 , in the example shown, in particular, thecuff locking device 20 is preferably located on the area above the heel of the boot, straddling between theshell 2 and thecuff 3, and is structured so as to be able to selectively -
- rigidly lock the
cuff 3 toshell 2 preferably in a given position in which thecuff 3 is tilted forward with respect to the vertical of a pre-set angle, thus preventing any pivoting movement of thecuff 3 on theshell 2; and - completely unblock/release the
cuff 3 from theshell 2 so as to allow thecuff 3 to freely pivot on theshell 2 about axis A, while remaining on the midplane of the boot.
- rigidly lock the
- In more detail, in the example shown, the
cuff locking device 20 is preferably structured so as to be able to rigidly lock thecuff 3 to theshell 2 in a given downhill position in which thecuff 3 is tilted forward with respect to the vertical of an angle preferably, though not necessarily, ranging between 3° and 30°. - Operation of the
ski boot 1 is easily inferable from the description above, and does not require additional explanation. - The advantages correlated to the particular structure of
transversal stiffening insert 9 are remarkable. - The particular shape of
transversal insert 9 prevents the ends of the auxiliary locking clamp of the toe piece of the Telemark ski binding device which is sold by the Italian company ATK RACE S.R.L. under the name “Newmark”, from directly abutting on plastic- or composite-materialrigid casing 6, thus ensuring a more firm and rigid locking ofshell 2 on the backside of the downhill ski. Increased rigidity which brings into a perceptible improvement in the response speed of the ski to the movements of the user. - In addition, the particular shape of
transversal insert 9 allows theski boot 1 to be used with numerous other ski-mountaineering or Telemark ski binding devices currently found on the market, such as, for example, the Telemark ski binding devices sold by the American company OLYMPUS MOUNTAIN GEAR LLC under the name “TTS”, the ski-mountaineering ski binding devices sold by the Norwegian company MOONLIGHT under the name “Pure Tele”, or the Telemark ski binding devices sold by the French company THE M-EQUIPMENT under the name “Meidjo”. - Clearly changes and variations may be made to the
ski boot 1 disclosed above without, however, departing from the scope of the present invention. - For example, front sole 7 could also be made in one piece with the
bottom wall 8 ofrigid casing 6, or could be secured in removable manner to thebottom wall 8 ofrigid casing 6 via anchoring screws.
