Description
FIELD OF THE INVENTION
[0001] The invention relates to a footlet provided with a part
manufactured by knitting on an apparatus for reciprocating knitting
that includes a ring-shaped opening delimited by an edge and
comprises an elastic strip that extends along the edge of the
opening.
[0002] The invention also relates to a method for fabricating such
a footlet.
BACKGROUND OF THE INVENTION
[0003] A footlet known from WO2008072048A1 is used for partial
coverage of the foot of a person. The footlet in use extends over
the heel, the lower side of the foot and over the toes. A middle
part also extends slightly along the lateral sides of the foot. A
large part of the upper side of the foot is not covered by the
footlet. When wearing partly open shoes, the footlet is hidden from
the view and the footlet affords the wearer a comfortable feeling.
Because the footlet is seamless, there are no seams that can cause
undesired pressure marks on the foot. The toe part and the heel
part are provided with a relatively small elastic strip. The heel
part is pressured against the heel of the person by the elastic
strip and the footlet remains firmly around the foot of the
person.
[0004] In contrast tot ordinary socks and stockings that are
usually made for each shoe size or two shoe sizes, footlets are
usually made in only two or three sizes. The advantage is that in a
shop the shelf space needed is limited and the supply management
easy. As a result the footlets need to be suitable for a relative
large range of foot sizes, the footlet needing to fit comfortably
at each foot size.
[0005] A disadvantage of the known footlet is that the footlet is
worn by persons with different foot sizes and for persons with a
relatively large foot, the relatively narrow and only on the toe
part and the heel part provided elastic strip presses with
relatively large power on the foot as a result of which the elastic
strip can be felt as pressing. By persons with a relatively small
foot when there is not enough power by the elastic strip on the
foot, there is the risk that the footlet shifts off the foot. A
further disadvantage of the relatively narrow elastic strip is that
it tends to curl up with the knitted part, which is experienced as
irritating.
[0006] Although it is possible to knit the elastic strip directly
when knitting the footlet on an apparatus for reciprocating
knitting, it is also common to stitch the elastic strip in a
separate process to the knitted part after manufacturing the
knitted part. This demands an extra manufacturing step. It is also
possible to manufacture the footlet on an apparatus for
reciprocating knitting after which at least at the toe part a by
reciprocating knitting knitted tubular part is closed by
stitching.
SUMMARY OF THE INVENTION
[0007] The invention intends to provide an easy to manufacture
footlet, the footlet remaining in use firmly in contact with the
foot.
[0008] This object is achieved with the footlet according to the
invention in that the elastic strip comprises an elastic tape
attached to the edge of the knitted part by an adhesive, the
knitted part during applying of the elastic strip being cut off at
least partly along the edge of the ring-shaped opening so that a
lateral side of the elastic strip almost coincides with a lateral
side of the edge of the ring-shaped opening.
[0009] Fasten the elastic strip by an adhesive to the edge of the
knitted part is relatively easy, the cutting of the knitted part
can be performed immediately before, during or immediately after
applying the elastic strip. By cutting off the knitted part during
applying the elastic strip on the edge of the ring-shaped opening,
it is possible to apply the elastic strip and to cut off the
knitted part along the edge at the same time in one single
apparatus. Thereby the elastic strip is quickly and accurately
applied.
[0010] If first the knitted part would be cut off and only later in
another apparatus the elastic strip would be applied, the edge of
the opening needs to be aligned accurately with respect to the
elastic strip, to be sure that the elastic strip coincides over the
entire length thereof with a lateral side of the edge of the
ring-shaped opening or on a same relatively short distance of some
millimetres. This problem is prevented with the footlet according
to the invention in that in one apparatus an apparatus for applying
the elastic strip and a cutting apparatus for cutting off the edge
are aligned with reference to each other. First cutting off the
knitted part and only later applying the elastic strip further has
the disadvantage that herewith the risk exists that in the time
between the cutting off on the one apparatus and the applying of
the elastic strip in the other apparatus, the knitted footlet falls
apart along the cut off edge. Also this problem is prevented with
the footlet according to the invention. Due to the coinciding of or
the constant distance between the elastic strip and the cut off
edge it is visible in the footlet, that at the same time the
elastic strip has been applied and the knitted part has been cut
off.
[0011] Because the lateral side of the edge and the lateral side of
the elastic strip almost coincide a finished appearance is
established. Because the elastic strip is attached to the cut edge
of the knitted part by an adhesive, the elastic strip prevents the
knitted cut part from falling apart and unravelling.
[0012] Although the edge limiting the ring-shaped opening is
endless it does not form a ring with a constant diameter like with
a knee-sock, the edge extending around the leg of the person.
[0013] Applying the elastic strip on the edge happens gradually
first attaching a first end of the elastic strip on the edge, after
which the rest of the strip is attached until finally the other
second end is attached to the edge.
[0014] It is noted that from KR101599276B1 a product is know, that
is composed from two plain and flat layers attached to each other
along the circumference, one layer provided with an opening. On the
plain knitted layer provided with an opening a silicone edge has
been applied by screen-printing. Because the knitted part of the
footlet according to the invention is manufactured on an apparatus
for reciprocating knitting, during knitting augmenting and
diminishing the number of stitches in order to form for example a
toe part and/of a heel part, the knitted part can not be placed
plainly and the method known from KR101599276B1 is not applicable
on footlets knitted on an apparatus for reciprocating knitting.
[0015] The elastic strip can have each desired width as a result of
which the pressure on the foot can easily be spread so that the
footlet is comfortable around the foot in case of relatively large
feet as well as relatively small feet. As a result of the
relatively large width of the elastic strip undesired curling up is
prevented easily. Because of the adhesive no stitch seams are
needed for attaching the elastic strip to the knitted part.
[0016] It is noted that from WO2016058864 a footlet is known that
is provided in the heel part and the toe part from an elastic
strip, only the heel part being provided with the anti-slip
element. Because the knitted heel part is not cut off, letting
coincide the lateral side of the anti-slip element with the lateral
side of the edge of the heel part is relatively complicated. The
risk exists that the part of the knitted part that extends above
the anti-slip part, curls around the anti-slip part.
[0017] It is noted that from KR1020130042718A a sock is known that
is composed of a bottom part and a belt shaped upper part. The
bottom part and the belt shaped part are cut out in the desired
final form. Thereafter the elastic strap is applied. Subsequently
ends of the belt shaped part are attached to each other. This sock
does not comprise a part manufactured on a knitting machine for
reciprocating knitting that comprises an edge limited by a
ring-shaped opening. Furthermore by this sock the belt shaped party
is not cut off during applying of the elastic strip.
[0018] An embodiment of the footlet according to the invention is
characterized in that the knitted part comprises a heel part, a toe
part and a middle part located between the heel part and the toe
part, which middle part comprises sides extending on both sides
between the heel part and the toe part, the edge limiting the
opening comprises an edge of the toe part, edges of both lateral
sides of the middle part and an edge of the heel part.
[0019] In case of such a footlet the edge rests against the back of
the heel and on the foot. The size of the opening depends upon the
form of the shoe in which the footlet is worn. The footlet is
preferred to be almost not visible when wearing the accompanying
shoes. In case of shoes like sneakers the footlet can almost cover
the entire upper side and the opening is smaller than in case of
footlets to be worn in open shoes like ballerinas.
[0020] Another embodiment of the footlet according to the invention
is characterized in that the elastic strip extends almost along the
entire edge of the toe part, the middle part and the heel part of
the knitted part.
[0021] Because the elastic strip extends almost along the entire
edge of the knitted part, the force on the foot that is exercised
by the elastic strip is spread over almost the entire circumference
of the footlet. Furthermore the elastic strip along almost the
entire edge of the knitted part makes it look finished
appearance.
[0022] Another embodiment of the footlet according to the invention
is characterized in that the knitted part comprises a toe part, the
edge limiting the opening comprising a circular edge of the toe
part.
[0023] Such a footlet only covers the toes and a small part of the
end of the foot. The tendency of such footlets to shift off the
foot, is effectively prevented by the elastic tape.
[0024] Another embodiment of the footlet according to the invention
is characterized in that the knitted part is knitted
seamlessly.
[0025] Because the knitted part is seamless and the elastic tape is
attached to the knitted part by an adhesive, de entire footlet is
seamless. As a result undesired pressure marks are prevented
easily. Furthermore the number of processes that is needed for
manufacturing the footlet is minimal as a result of this because
the knitted part is knitted as a whole seamlessly, after which
subsequently the elastic tape is applied in one single
manufacturing step and cut off together with the footlet.
[0026] Another embodiment of the footlet according to the invention
is characterized in that ends of the elastic strip overlap and are
attached to each other by an adhesive.
[0027] In this way the elastic strip extends as an endless strip
along the entire circumference of the knitted part and forms a
finished appearance. Furthermore the endless elastic strip makes
that the force on the foot is spread equally.
[0028] Another embodiment of the footlet according to the invention
is characterized in that the elastic strip is manufactured of a
material, which material itself comprises anti-slip features.
[0029] Because the material itself comprises anti-slip features,
that is that it has features that sliding of the material over the
foot is easily prevented or hindered, the force on the foot that by
amplifying of the elastic strip can be relatively little, which
increases the comfort to wear. The anti-slip features easily
prevent the undesired shifting off the foot of the footlet is. If
the elastic strip extends almost around the entire edge or around
the entire edge of the knitted part, along the entire edge the
footlet can not shift off the foot.
[0030] If the material of the elastic strip is manufactured of a
material, that itself has no anti-slip features, the preventing the
footlet from shifting off the foot has to be performed entirely by
the stretch features of the elastic strip, the footlet with a
stretched elastic strip laying against the foot.
[0031] Another embodiment of the footlet according to the invention
is characterized in that the material comprises silicones.
Silicones can easily be applied, in a relatively small tape, in any
desired width as an elastic strip on the footlet.
[0032] Another embodiment of the footlet according to the invention
is characterized in that the elastic strip is applied to the
knitted part by hot-melt as an adhesive.
[0033] With hot-melt the elastic strip can be attached to the
knitted part quickly and firmly.
[0034] Another embodiment of the footlet according to the invention
is characterized in that the elastic strip has a width of 5-15
millimetres, preferably 5-10 millimetres and even more preferably
about 5 millimetres.
[0035] Such a width ensures a good spread of the force on the foot,
a good anti-slip effect and a good comfort of wear.
[0036] Another embodiment of the footlet according to the invention
is characterized in that the elastic strip is provided with
passages.
[0037] Such passages serve as ventilation by the elastic strip
manufactured for example from silicones. Such passages are
particularly suitable if the material of the elastic strip itself
is not sufficient ventilating for transpiration of the foot of the
person that wears the footlet.
[0038] The invention further relates to a method for manufacturing
such a footlet, an apparatus for reciprocating knitting
manufacturing a knitted part that comprises an ring-shaped opening
limited by an edge and an elastic strip extending along the edge of
the opening, the elastic strip comprising an elastic tape, which
elastic tape is attached to an edge of the knitted part with an
adhesive and the knitted part along the edge of the ring-shaped
opening during applying of the elastic strip is cut off at least
partly so that a lateral side of the elastic strip almost coincides
with a lateral side of the edge of the ring-shaped opening.
[0039] Attaching the elastic strip with an adhesive to the edge of
the knitted part is relatively simple, cutting off the knitted part
can easily be performed immediately before, during or immediately
after applying the elastic tape. By cutting off the knitted part
during applying of the elastic strip on the edge of the ring-shaped
opening, the elastic strip can be applied at the same time that the
knitted part will be cut off along the edge in one apparatus.
Thereby the elastic strip is quickly and accurately applied.
[0040] Because the lateral side of the edge and the lateral side of
the elastic strip almost coincide a finished appearance is
obtained, preventing the falling apart of the knitted part along
the edge by the elastic strip.

DESCRIPTION OF PREFERRED EMBODIMENTS
[0051] FIG. 1 shows a footlet 1 according to the invention provided
with a knitted part 2 and an elastic strip 3. The knitted part 2 is
manufactured by an apparatus for reciprocating knitting by only
reciprocating knitting. As a result a seamless knitted part 2 is
obtained. The seamless knitted part 2 is provided with a heel part
4, a middle part 6 connected by knitting formed lines 5 with heel
part 4 and a toe part 8 connected by knitting formed lines 7 with
the middle part 6. By increasing and diminishing during
reciprocating knitting the desired form of the knitted part 2 can
be obtained. The middle part 6 comprises sides 9, 10 extending on
both sides between the heel part 4 and the toe part 6. The sides 9,
10 are attached to each other by the sides 11, 12 of the heel part
4 and the toe part 8. After manufacturing of the seamlessly knitted
part 2, an elastic tape 14 is attached with an adhesive along the
four sides 9-12, a first end 15 extending further than a second end
16 so that the ends 15, 16 overlap over a part 17. The ends 15, 16
are attached to each other with the same adhesive as with which the
elastic tape 14 is attached to the seamlessly knitted part 2.
Preferably during attaching the elastic tape 14 with the adhesive
the seamlessly knitted part 2 is cut off along an external lateral
side 18 of the elastic tape 14 so that the lateral side 18 of the
elastic tape 14 coincides with the seamlessly knitted part 2 formed
by the sides 9-12. One can use one single apparatus with which the
elastic strip can be applied as well as at the same time the
knitted part can be cut off along the edge. The lateral side 18
limits an opening 19 through which a foot in the footlet 1 can be
inserted. This is clearly visible in FIG. 2. In this FIG. 2 it is
also clearly visible that with this the knitted part is cut.
Because the elastic tape 14 is attached to the seamlessly knitted
part 2 with adhesive, falling apart and/or unravelling is easily
prevented. The elastic tape 14 is for example is wrapped on a
roller and already provided with adhesive so that by unwinding the
elastic tape 14 off the roller the side provided with adhesive can
be pressed directly against the knitted part 2. The elastic tape 14
is preferably attached by hot-melt as adhesive to the seamlessly
knitted part 2. Herewith the knitted part 2 is preferably turned
inside out so that the elastic tape 14 van easily be attached to
the side turned to the outside, while the side turned to the inside
is supported by a work table. Herewith the elastic tape 14 van be
pressed firmly against the side turned to the outside and at the
same time the knitted part 2 and if desirable also the elastic tape
14 can be cut at the desired width. Furthermore the formed footlet
1 according to the invention will be turned back so that the formed
elastic strip 3 is on the inner side of the footlet 1 that is
turned to the foot 21.
[0052] The elastic tape 14 attached to the seamlessly knitted part
2 forms the elastic strip 3 of the footlet. The endless elastic
strip 3 has a width B of 5-15 millimetres, preferably 5-10
millimetres and even more preferably about 5 millimetres. The
thickness of the elastic strip 3 is relatively thin, for example
0.05-0.5 preferably about 0.1 millimetre, as a result of which
there is no pinching between the foot 21, the elastic strip 3 of
the footlet 1 and the shoe around. Comparatively, the thickness of
an elastic strip knitted to the knitted part of the footlet
according to the state of art is 1-2 millimetres.
[0053] FIG. 3 shows a foot 21 of a person that is provided with the
footlet 1 of FIG. 1. The heel part 4 herewith lies around the heel
of the foot 21. The toe part 8 lies herewith over the toes of the
foot 21. The middle part 6 extends with a bottom part 22 over the
lower part of the foot 21 en extends with lateral parts 23, 24
along the lateral sides of the foot 21.
[0054] The elastic strip 3 lies over the full circumference of the
footlet 1 against the foot 21, as a result of which a good
distribution of the pressure is acquired.
[0055] The elastic strip 3 is preferably made of a material, which
material itself has anti-slip features. Such a material is for
example silicones.
[0056] Although it is also possible that the elastic strip tape is
made of a material that has little friction with the foot 21, in
which case the footlet 1 only sticks around the foot 21 because of
the elastic effect of the elastic strip 3. In case of a silicon
elastic strip 3 the footlet 1 needs to be stretched considerably
less to guarantee enough fixation on the foot 21 than in case of an
elastic tape of a material that has less friction with the
foot.
[0057] FIG. 4 shows a perspective view of a second embodiment of
footlet 41 according to the invention. The footlet 41 comprises a
seamlessly knitted part 2 and an elastic strip 43. The footlet 41
differs from the footlet 1 in that the elastic strip 43 comprises
two elastic tapes 44, 45. The first tape 44 extends over a part of
the side 10 of the middle part 6, the full side 11 of the heel part
4 and a part of the side 9 of the middle part 6. The second tape 45
extends over a part of the side 10 of the middle part 6, the full
side 12 of the toe part 4 and a part of the side 9 of the middle
part 6. Ends 46 of the first tape 44 are herewith at a distance A
of a couple of millimetres of ends 47 of the second tape 45.
[0058] The elastic tapes 44, 45 are provided with passages 48 for
ventilation of the skin of the foot 21. Furthermore diminish these
passages 48 the needed amount of material of the elastic strips 44,
45. The shape of the passages 48 can be arbitrary.
[0059] FIG. 5 shows a perspective view of the third embodiment of a
footlet 51 according to the invention. The footlet 51 comprises a
seamlessly knitted part 52 and an elastic strip 53. The seamlessly
knitted part 52 comprises a heel part 54, a middle part 56
connected by knitting formed line 55 with heel part 54 and a toe
part 58 connected by knitting formed line 57 with the middle part
56. The toe part 58 is considerably longer than the heel part 54.
Furthermore the opening 59 limited by the elastic strip 53 is
considerably smaller than the opening 19 limited by the elastic
tape 14 of the footlet 1. The footlet 51 is suitable for wearing in
for example sneakers while the footlet 1 is suitable for wearing in
ballerinas. When wearing footlet 1 in sneakers a part of the upper
side of the foot that lies bare touches the inner side of the
sneaker, what will be experienced as unpleasant. When wearing the
footlet 51 in ballerinas, the upper side of the toe part 58 of the
footlet 51 is visible, what will be experienced as undesired. The
footlet 51 differs further from the footlet 1 in that the elastic
strip 53 comprises two concentric elastic tapes 60, 61, that are at
a distance C of each other. The elastic tapes 60, 61 are for
example as wide as the distance C. The distance C is for example
3-5 millimetres.
[0060] FIG. 6 shows a perspective view of a fourth embodiment of a
footlet 71 according to the invention. The footlet 71 comprises a
knitted part 72 and an elastic strip 73. The knitted part 72
comprises a heel part 74, a middle part 76 connected by knitting
formed lines 75 with heel part 74 that is tubular at a side turned
away from the heel part 74. By cutting off the tubular part 78
partially folding double and a stitch processing a toe part 79 is
formed that through a seam 80 is connected to the tubular part 78.
The elastic strip 73 is as well as the footlet 1 provided with an
elastic tape 14 that is attached to the knitted part 52 with an
adhesive.
[0061] FIG. 7 shows a perspective view of a fifth embodiment of a
footlet 81 according to the invention. The footlet 81 comprises a
knitted part 82 and an elastic strip 83. The elastic strip 83
limits an opening 84 in which only the anterior part of the foot,
comprising the toes and a small abutting part, can be put. The
elastic strip 83 that extends along the entire circumference of the
opening 84 is attached to the part 82 preferably seamlessly knitted
en cut off around. The knitted part 82 comprises an anterior
knitted part 85 that by knitting formed lines 86 is attached to a
posterior knitted part 87.
[0062] FIG. 8 shows a perspective view of a sixth embodiment of a
footlet 91 according to the invention, that differs from the
footlet 81 in that the footlet 91 is provided with a complementary
elastic band 92 that can be fastened around the heel of a person.
Thereby undesired coming off of the footlet 91 is further
prevented.
[0063] In all footlets 1, 41, 51, 71, 81, 91 the knitted part is
first manufactured so that the opening 19, 59, 84 is fully formed,
after which along the edge of the opening the elastic strip is
attached.
[0064] Of course it is also possible to provide the footlets 1, 41,
51, 71, 81, 91 with a double produced elastic strip 53 or the
footlet 51 of the single elastic tape 14. It is also possible to
construct the elastic tape of more than two parallel tracks.
[0065] It is also possible to for example apply extra anti-slip
elements in the heel part.
[0066] The ends 15, 16 can be positioned on any position along the
sides 9-12.
[0067] The heel part 4 en the toe part 8 can be produced identical
leaving it to the user which part she wishes to use as heel part 4
and toe part 8. The heel part 4 and the toe part 8 can be produced
differently, the heel part 4 being adapted to the shape of the heel
of the foot 21 while the toe part 8 is adapted to the toes of the
foot 21.
[0068] It is also possible that the elastic strip 3, 53, 73, 83, 92
is almost endless wherein the ends 15, 16 do not overlap but being
at a relatively short distance apart. Also these elastic strips can
be provided with passages 48.
[0069] The knitted part of the footlet 1, 41, 51, 71, 81 is knitted
of fibres or yarns of cotton, polyamides, polypropyleen or another
synthetic or another material or a combination thereof.
[0070] It is also possible to manufacture the knitted part of the
footlet 1, 41, 51, 71, 81 not seamlessly. However this has the
disadvantage that herewith seams are inevitable.
[0071] The material with anti-slip features is for example
silicones that are sold for example by CHT, Dow Corning, Alpina or
other companies, for example in the name of Alpatec. It is also
possible to use other materials than silicones with anti-slip
features, for example PVC, silicones free Faitplast With Me
etc.
[0072] It is possible to apply the anti-slip material transparent
or in a desired colour.
[0073] Instead of hot-melt also another adhesive can be applied.
The cutting off can be performed with a cutting tool or laser.
