[0001] The present invention relates to a ski boot, comprising a shell with overlapping
flaps to which at least one quarter is articulated and with which a soft innerboot
can be internally associated.
[0002] Currently, these conventional ski boots have the drawback that they require the user
to open out the ends of the flaps in order to open the front tongue of the innerboot
and thus insert the foot inside it.
[0003] Since the shell is obtained by injection-molding thermoplastic material, which has
a given degree of rigidity, this operation is not easy, also because the user is usually
wearing gloves in this situation.
[0004] This problem worsens especially at low temperatures, when plastics tends to become
more rigid.
[0005] Furthermore, the quarter is usually secured at the upper overlap region of the shell
flaps, creating further difficulties for inserting the foot due to the presence of
the flaps of the quarter, which must also be kept open.
[0006] The principal aim of the present invention is therefore to solve the described technical
problems, eliminating the drawbacks of the mentioned prior art, by providing a ski
boot, comprising at least one quarter articulated to a shell having overlapping flaps
and comprising a soft innerboot, that allows the skier to rapidly and easily insert
his foot inside said innerboot.
[0007] Within the scope of the above aim, an important object is to provide a ski boot which
allows optimum foot insertion even in case of low temperatures and if the user is
wearing gloves.
[0008] Another important object is to provide a ski boot which allows to achieve optimum
distribution of efforts at the metatarsal region.
[0009] Another object is to provide a ski boot which associates with the preceding characteristics
that of allowing to vary its technical characteristics without specific mechanical
devices.
[0010] Another object is to provide a ski boot which is structurally simple and has low
manufacturing costs.
[0011] This aim, these objects and others which will become apparent hereinafter are achieved
by a ski boot comprising at least one quarter articulated to a shell having overlapping
flaps and a soft innerboot, characterized in that it further comprises a semirigid
tab that can be gripped by the user and is at least partially interposed between said
innerboot and said flaps.
[0012] Further characteristics and advantages of the invention will become apparent from
the following detailed description of some particular but not exclusive embodiments,
illustrated only by way of non-limitative example in the accompanying drawings, wherein:
figure 1 is a lateral perspective view of the ski boot with the end flaps of the quarter
in open position;
figures 2, 3, 4, and 5 are lateral perspective views of the boot with an adjustable-height
quarter associated therewith;
figure 6 is a view, similar to figure 1, of another embodiment illustrating a connection
between the tongue of the innerboot and the tab;
figure 7 is a view, similar to the preceding one, of another embodiment in which there
are means for temporarily locking the position of the tab with respect to the flaps
and means for limiting the opening of said flaps;
figure 8 is a partial side view of a boot according to a further aspect of the invention;
figure 9 is a detailed section view of the toe portion of the boot of figure 8;
figure 10 is a partial side view of a boot according to still a further aspect of
the invention;
figure 11 is a detailed section view of the toe portion of the boot of figure 10.
[0013] With reference to the above figures, the reference numeral 1 designates the ski boot,
which comprises a shell 2 having a first flap 3 and a second flap 4 which can be moved
mutually apart and can be mutually overlapped and secured by conventional fastening
means, such as levers for example, during use.
[0014] At least one quarter 5 is articulated to the shell 2 and has a third flap and a fourth
flap which can be secured at the first and second flaps by conventional means, such
as levers for example.
[0015] A soft innerboot 6 is arranged inside the shell 2 and is provided with a tongue 7
at the front. One end of the tongue is associated with the innerboot 6 approximately
at the toe region, so as to allow it to shift forwards during foot insertion.
[0016] The ski boot comprises a tab 8 made of semirigid material and interposed between
the tongue 7 of the innerboot 6 and the first 3 and second 4 flaps of the shell 2.
[0017] The tab 8 can be rigidly coupled to the shell 2 at one end, preferably proximate
to the toe region, where it can protrude for better locking of the assembly.
[0018] Advantageously, said tab 8 has, proximate to its upper perimetric edge 9, a grip
means for the user, such as an opening 10 formed transversely to said tab.
[0019] The user can in fact grip the tab at its opening so as to move the first flap 3 and
the second flap 4 mutually apart simply by applying forward traction to said tab.
[0020] Accordingly, the opening out of the first and second flaps is assigned to a passive
element which by virtue of its shape and arrangement allows to easily achieve this
opening when the user simply grips said element and applies a slight effort to it.
[0021] A second aspect of the present invention is the fact that if the quarter 5 is articulated
to the shell 2 by virtue of suitable studs 11 that are slideable within suitable first
slots 12 formed on said shell, so as to obtain a quarter 5 whose height is adjustable,
a boot is obtained in which it is possible to vary the flexibility simply by varying
the height of said quarter.
[0022] This variation in fact entails affecting a larger or smaller part of the tab 8, which
reacts differently by virtue of a "flat-spring" effect that can be obtained.
[0023] Accordingly, one obtains greater rigidity if the quarter 5 is arranged in the lowest
possible condition, whereas there is a higher flexibility effect when the quarter
is placed in its uppermost position.
[0024] It has thus been found that the invention has achieved the intended aim and objects,
a ski boot having been provided that allows the user to rapidly and easily open out
the flaps of the shell, so as to insert his foot in the innerboot rapidly and easily.
[0025] This solution remains effective even at low temperatures, since the flap opening
effort is assigned only to the tab and the effort that can be applied by the user
is at the same time very small.
[0026] The boot according to the invention is susceptible to numerous modifications and
variations, all of which are within the scope of the same inventive concept.
[0027] Thus, for example, figure 6 shows a ski boot 101 in which the tab 108 is associated
not only with the shell 102 at one of its ends but also with the tongue 107 of the
innerboot 106.
[0028] Advantageously, this connection occurs proximate to the opening 110 and can be achieved
by providing a suitable second slot 113 formed longitudinally with respect to the
tab 108; a first lug 114 is slidingly associated at the second slot, is rigidly coupled
to the underlying tongue 107, and protrudes therefrom.
[0029] As shown in figure 7, it is also possible to provide means for limiting the mutual
spacing of the first flap 103 and of the second flap 104; said means can be constituted
for example by a suitable wing 115 which protrudes from the perimetric edge 116 of
the first flap 103 towards the second flap 104. A suitable third slot 117 is formed
transversely to the shell 102 on said wing, and a second lug 118, which is rigidly
coupled to the outer surface of the second flap 104 and protrudes therefrom, is selectively
slideable at said third slot.
[0030] Figure 7 also shows means for temporarily locking the position of the tab 108 with
respect to the first flap 103 and the second flap 104. These means are preferably
constituted by one or more notches 119 formed at the lateral edges 120 of said tab
108.
[0031] Said notches can in fact be arranged selectively at the upper edge 121 of the shell
or at the lateral edges 122 of the first and second flaps, so as to allow to keep
the tab 108 in the chosen open position.
[0032] Figures 8-9 show a ski boot 201, according to a further aspect of the invention,
comprising a waterproof seal member 220, arranged between the first flap 203 and the
semirigid tab 208. The waterproof seal member 220 is preferably made of rubber, or
other resilient material, and prevents water from infiltrating the boot.
[0033] Figures 10-11 show a ski boot 301, according to still a further aspect of the invention,
comprising a waterproof seal member 320, arranged between the first flap 303 and the
semirigid tab 308, as in the boot of figures 8-9.
[0034] The waterproof seal member 320 also has a fastening member 321 for fastening the
seal member 320 to the shell.
[0035] The fastening member 321 is illustrated as a mushroom-shaped projection inserted
in an adapted hole in the shell but it can also be a rivet or similar. The upper head
of the rivet would have to be waterproofed to prevent water infiltration.
[0036] These shown solutions therefore also allow to achieve the intended aim and objects,
further increasing comfort for the user as regards inserting his foot in the boot.
[0037] The materials and the dimensions of the components of the structure, as well as the
number of notches and the position of the second slot 113 and of the wing 115, may
of course be the most pertinent according to the specific requirements.
