[0001] The present invention relates to the field of hosiery and, more precisely, to a garment
of hosiery such as, but not exclusively, a stocking or pantyhose, having a new structure.
[0002] As is known, articles of the above-mentioned type can be constituted by various parts
having non uniform characteristics for the purpose of making each part appropriate
for its own function. For example, in a women's stocking or pair of pantyhose, various
parts can be identified (elastic band, girdle, thigh, ankle and toe) which differ
from one another both in the type of yarn used and the resulting stitch. The elastic
band, which functions to support the garment, requires a very resistant yarn (for
example, Lycra®); the toe, which is the part of the stocking or pantyhose most exposed
to wear, requires a yarn and a type of knitting able to withstand the continuous stresses
of the foot; the girdle, when present, requires a yarn and a type of stitch able to
exert the compression required by the particular article; whereas for the leg, a yarn
of appropriate count (generally lower than the others) is used. Different yarns and
stitch types are used for the various parts of the garment of hosiery in order to
make it as adaptable as possible to the various body shapes of the people who wear
it. In fact, while various sizes are made of a single article, it is practically impossible
to foresee the countless shapes of potential customers. Consequently, when one of
the parts of the garment of hosiery is subjected to a particular stress, this action
is transmitted to the adjacent parts of the same and, indirectly, to the corresponding
parts of the body.
[0003] The comfort of the foot is of particular importance. In fact, the toes are the parts
of the body most exposed to the stresses induced on the garment of hosiery. There
are two causes of said stresses. On the one hand, within the ambit of a single standard
size of garment, both the size and shape of the foot can vary considerably; on the
other hand, while the foot has an asymmetric shape, the toe of the garment of hosiery
is always made symmetrically, and it is the toes of the foot that stretch appropriately
the toe of the garment to adapt it to their shape. For both of these reasons, there
is a very heterogeneous state of tension in the toe of the garment and, correspondingly,
a heterogeneous and sometimes uncomfortable stress for the toes. The compression which
the toe of the garment of hosiery exercises on the toes is accentuated also by the
fact that it is realized with particularly resistant yarns in appropriate stitch types.
Consequently, the toe of the garment of hosiery is clearly distinguishable from the
rest of the garment, making it rather unsuitable when using particularly open footwear,
such as summer footwear. To avoid this aesthetic inconvenience, so-called "sheer toes"
are realized, which are toes having the same stitch density as the rest of the garment
of hosiery. This, however, makes them less resistant.
[0004] Similar problems, though of lesser importance, exist in other portions of the garment
of hosiery, for example the ankle or the knee, where the garment is subjected to tensions
which are concentrated as a result of the anatomic articulations and/or the scarce
compliance of the part of the body in contact with the garment.
[0005] The principle object of the present invention is therefore to provide a garment of
hosiery in which the tensions to which the garment is locally subjected, as a result
of different anatomical shapes, are absorbed, nullifying or drastically limiting their
transmission to the adjacent portions of the garment.
[0006] A particular object of the present invention is to provide a garment of hosiery of
the above-mentioned type able to adapt perfectly to any shape of the foot or leg within
the ambit of the same size, thus eliminating annoying stresses which are otherwise
transmitted to the toes, through the toe of the garment.
[0007] A further object of the present invention is to provide a garment of hosiery of the
above-mentioned type, in particular having a "sheer toe," in which the transmission
of tensions to the toe of the garment of hosiery is greatly reduced, thus reducing
the risks of damage and maintaining unaltered the appearance.
[0008] These objects are accomplished by the garment of hosiery whose essential features
are indicated in claim 1. In summary, the presence of an elastic band which is continuous
between two consecutive tubular portions of hosiery and has a lower elastic constant
than that of the two adjacent parts results in the absorption of the tensions which
the two portions otherwise would reciprocally transmit.
[0009] Further characteristics and advantages of the garment of hosiery according to the
present invention will become apparent in the following description of one of its
possible embodiments, given as an example and not limitative, with reference to the
attached drawings in which:
- figure 1 is a schematic view of the toe of a garment of hosiery according to the present
invention in a resting condition;
- figure 2 shows schematically the distribution of the tensions acting on the foot of
the garment of hosiery according to the present invention when worn;
- figure 3 shows schematically other possible ways to use the invention.
[0010] With reference to figure 1, the foot of a generic garment of hosiery, for example
a women's stocking or a pair of pantyhose, is indicated with 1, and the toe of the
garment is indicated with 2. Foot 1 and toe 2 can be made in a conventional way, using
usual yarns for this type of application (e.g. Lycra®), and, in particular, toe 2
can be realized in a more resistant yarn and different stitch structure than those
of foot 1, or foot 1 and toe 2 can have identical characteristics of material and
structure (i.e. "sheer toe").
[0011] According to the invention, between toe 2 and foot 1 a continuous band 3 is provided.
Band 3 is characterized by an elastic coefficient which is lower than that of the
two adjacent portions and, therefore, when subjected to the same applied tension,
it has a greater stretching capacity.
[0012] As shown in figure 2, the tensions, generally indicated with T, which are induced
on toe 2 and foot 1 of the garment by the asymmetry of the foot are greater the more
the fore part of the foot differs from the symmetrical form of the toe of the garment.
These tensions discharge and are largely absorbed by elastic band 3, which is interposed
between the two portions and dilates proportionally to the applied tension. In this
way, the tension transmitted to toe 2 is only a residual tension and is practically
negligible in comparison with the tension that would be transmitted in the absence
of band 3. Similarly, tension T1, which discharges on the heal, is correspondingly
lower than it would be in the absence of band 3. In other words, the foot of the garment
is subjected to the same stretching to which it would be subjected in the absence
of elastic band 3, but with the difference that the tensions induced by said stretching
are largely absorbed, in an amount proportional to their intensity, by elastic band
3. In this way, the stresses which discharge on the toes and heal are considerably
lower, if not negligible, in comparison with those generated by conventional garments
of hosiery.
[0013] Similar reasoning can be applied to the different shape and size of the foot with
respect the standard size of the garment. As will be apparent to a technician in the
field, the tensions induced on toe 2 and foot 1 by those differences in shape and
size are absorbed by elastic band 3, which is obviously able to react not only in
the direction of tension T, but also in any other direction.
[0014] Besides resolving the problem of stresses in the area of the foot, the present invention
also provides an adequate solution to reduce the tensions which can be generated in
other parts of a garment of hosiery and can induce annoying stresses on the leg or
increase the risk of tearing the garment. As the example in figure 3 shows, an elastic
band 4 can be provided near the ankle, between foot 1 and leg 5 of the garment of
hosiery, or a pair of elastic bands 6a and 6b can be provided above and below the
knee portion 8 of the garment respectively between said portion and leg 5, on one
side, and between said portion and thigh 7 on the other. In all of these cases, the
presence of elastic bands between the tubular portions makes it possible to disconnect
the various portions from one another, preventing or substantially reducing the transmission
of tensions between one portion and the other.
[0015] The elastic band provided according to the present invention can be realized with
conventional techniques. Considering, for example, the case of the band applied between
the toe and the foot of a garment of hosiery, if the stitch corresponding to the foot
of the garment uses an elastic yarn such as Lycra® in all of its ranks, or in the
case of a "sheer toe", the band can be realized with an elastic yarn, such as Lycra®,
but having a finer count and with the same type of stitch. If, on the other hand,
the stitch of the foot is of alternating ranks or, in other words, a rank containing
an elastic yarn followed by a rank of yarn without elastomer, the band can be realized
using an elastic yarn in all the ranks or in alternating ranks, but with an elastic
yarn having a lower denier. Independently from the type of yarn used and the type
of construction of the stitch for the toe and foot of the garment, the lower elastic
constant of the band can be obtained by widening the stitch or, that is, decreasing
its density. All of the these ways, like other equivalent ones, are not described
in further detail since they are well known to experts in the field.
[0016] While in the present description reference has been made mainly to women's stockings
or pantyhose, it is clear that the same technical solution can be applied also to
men's socks, knee-high stockings and the like.
