Description
FIELD OF THE INVENTION
[0001] This invention relates to swimming caps for use in swimming,
and related water sports.
BACKGROUND
[0002] Swimming caps for covering the hair of a swimmer are known
to serve a number of functions. They prevent hair from dragging in
the water, which would otherwise slow and distract the swimmer. In
addition, the cap prevents hair that has detached from the
swimmer's scalp from clogging up filters etc. in swimming pools.
When made from a waterproof material, the cap may also provide a
protective covering that prevents the swimmer's hair from getting
wet. These caps also protect the wearer's hair and scalp from
chlorine.
[0003] To facilitate wearing a cap, a swimmer having long, hanging
hair will generally form their hair into a compact shape, such as a
bun or ponytail. The cap is subsequently placed over the head, so
that the hair is collected under the cap at the back of the head.
This results in a head profile that substantially follows the shape
of the skull except for a bulge, high at the back of the head,
where the hair is contained.
[0004] When swimming, the swimmer will generally adopt a posture in
which there is a dip between the back of the head and the
shoulders. This dip, around the nape of the neck, interferes with
the flow of water, adversely affecting the hydrodynamics of the
swimmer. With traditional swimming caps, this dip is accentuated by
the bulge created by the hair at the back of the head, worsening
the problem. Therefore, there exists a need to provide a swimming
cap that has improved hydrodynamics compared to known designs.
SUMMARY OF THE INVENTION
[0005] Accordingly, in a first aspect, the present invention
provides a swimming cap defining a cavity for accommodating a
wearer's head, wherein the cap further defines an enlarged volume
portion which, in use, is positioned at the nape of the wearer's
neck for containing the wearer's hair.
[0006] In traditional designs, the hair is generally collected over
the parietal and occipital bones of the skull. In caps of the
present invention, however, the enlarged volume portion positions
the hair lower, distal from the parietal bones of the skull. The
enlarged volume portion of the present cap preferably positions the
substantial part of the hair below the superior nuchal line and
external occipital protuberance of the occipital bone. Preferably,
the enlarged volume portion of the present cap positions the hair
so that a substantial part of the hair overlays the base of the
hairline at the back of the head.
[0007] By providing an enlarged volume portion to position a
wearer's hair at the nape of the neck, the cap of the present
invention provides means for partially filling the dip between the
back of the head and the shoulders that arises in common swimming
postures. Decreasing the size of this dip improves water flow over
this region. Thus, swimming caps of the present invention result in
improved hydrodynamics compared to traditional swimming cap
designs.
[0008] The swimming cap preferably has a shape approximating a
hollow dome, defining the cavity, having a crown surrounded by a
periphery, wherein a section of the periphery bulges to define the
enlarged volume portion of the cavity. As explained above, this
enlarged volume portion is positioned over the wearer's nape in
use, and provides space for storing the wearer's hair.
[0009] Preferably, the profile of the cap is such that, in use, it
has a substantially continuous gradient or slope between from the
crown to the enlarged volume portion i.e. it has a smooth profile
between the crown and enlarged volume portion with no significant
deflections (e.g. indentations or protrusions). This is to ensure
smooth water flow over the cap in order to minimise undesirable
water resistance.
[0010] Preferably, the cavity of the swimming cap has a volume
substantially matching the volume of the wearer's head. Having a
similar volume to the wearer's head ensures that the cap fits
closely to the head, minimising loose fitting regions that could
create hydrodynamic drag.
[0011] In some embodiments, the "wearer's head" is the 50.sup.th
centile female head, or a scaled version of this head. In other
embodiments, the "wearer's head" is the 50.sup.th centile male
head, or a scaled version of this head. In preferred embodiments,
the "wearer's head" is an average of the 50.sup.th centile female
head shape and 50.sup.th centile male head, or a scaled version of
this head.
[0012] Of course, the length of a wearer's hair will vary between
wearers. Preferably, the cap is able to accommodate hanging hair
extending .about.34 cm to 70 cm from the crown of the head.
[0013] Preferably, the swimming cap has a gripping section for
securing the cap to the wearer's head. The gripping section may
extend around an edge of the cap, the edge defining the opening of
the cavity. In certain embodiments, the gripping section completely
surrounds the opening of the cavity.
[0014] The gripping section may be elastic, so that compression of
the gripping section around a part of the head holds the cap in
place. Additionally, or alternatively, the section may be made of a
non-slip material that holds the cap in place through friction. For
example, the gripping section can be an elastomeric material, such
as a silicone rubber. The section may contact a wearer's skin, such
as the forehead, and/or the wearer's hair. The gripping section
provides a means to keep the cap in place on the wearer's head. It
may also facilitate putting the cap on, since a wearer may first
locate and secure a gripping section on their head before placing
the cap fully on the head.
[0015] The cap may be made from a porous or non-porous material.
The material may be elastic (in which case it may compress against
the wearer's head) or may be relatively inelastic (in which case it
may not compress against the wearer's head). Alternatively, it may
comprise both elastic and inelastic materials, either combined in
the same regions of the cap (e.g. in a layered construction, or
interwoven/interknitted with one another) or present in separate
regions. Examples of suitable materials include rubber materials,
such as silicone and latex, and textile materials such as polyamide
materials (eg. nylon) and Lycra.TM..
[0016] Preferably, the cap is at least partially made from a
textile material. The textile material may be a woven fabric,
preferably a stretch woven fabric. In preferred embodiments, the
cap is made from a textile material comprising both inelastic
threads (such as a polyamide material) and elastic threads (such as
Lycra.TM.). Preferably, the percentage of elastic threads (e.g.
Lycra.TM.) is about 25 wt %. Preferably, the percentage of
inelastic threads (e.g. polyamide) is about 75 wt %.
[0017] In preferred embodiments, the cap is made from a textile
material having a weight per square metre of 90-300 grams/m.sup.2.
For example, the cap may have a weight per square metre of
approximately 106 grams/m.sup.2.
[0018] Caps made from textile materials may be easier to adjust
once placed on the head than rubber caps. Rubber materials tend to
grip the head (both through compression and due to high levels of
friction) making it difficult to reposition the cap once it is
placed on the head. In contrast, textile materials tend to grip the
head to a lesser extent, facilitating repositioning.
[0019] The cap preferably has a streamlined exterior, for example,
the cap may have smooth exterior surfaces. This ensures that
hydrodynamic drag created by the exterior surface of the cap does
not negate the improved hydrodynamics resulting from the cap's
positioning of the hair.
[0020] The swimming cap may be a unitary construction, i.e., formed
from a single piece of material. For example, the cap may be a
single piece of moulded material/fabric. However, it is preferred
that the swimming cap comprises multiple panels joined by seams. A
multi-panel construction is advantageous for the construction of
the cap because the cap can be made to the desired shape by
choosing the location of panels and seams, instead of by moulding
or weaving the cap to this shape. Such a construction may also
increase the resilience of the cap. For example, it avoids the need
to have large expanses of material, which may be more prone to
ripping or unwanted deformation than multiple, smaller panels.
[0021] The panels may be joined to one another by stitching or by
bonding. Stitching is preferred because stitched seams may stretch
at a similar rate to the fabric. This minimises stresses in the cap
that could otherwise cause damage. Various seam types are possible,
but lapped seams are preferred, since these can be made to rest
relatively flat against the cap and minimise drag.
[0022] Advantageously, the swimming cap comprises a tactile or
visual position marker which, in use, is aligned with an anatomical
landmark on the wearer's head to ensure a correct wearing position
of the cap. In certain instances, a marker may serve as both a
tactile and a visual position marker.
[0023] By providing such a position marker, the wearer of the cap
can align the marker with an appropriate anatomical landmark (e.g.
the nose, the ears etc.) to ensure that the cap is correctly
fitted. Correct fitting ensures optimum comfort and/or optimum
performance.
[0024] In some embodiments, the location of a position marker on
the cap is determined by the location of an anatomical landmark on
the 50.sup.th centile female head, or a scaled version of this
head. In other embodiments, the location of a position marker on
the cap is determined by the location of an anatomical landmark on
the 50.sup.th centile male head, or a scaled version of this head.
In preferred embodiments, the location of a position marker on the
cap is determined by the location of an anatomical landmark on a
head which is the average of the 50.sup.th centile female head and
50.sup.th centile male head, or a scaled version of this head.
Tactile position markers are preferred (since the wearer may be
unable to visually check the position of the cap without the use of
an additional aid, such as a mirror, when the cap is fitted).
[0025] The position marker may, in use, be positioned, for example,
on the centre line of the wearer's forehead or on the centre of the
wearer's crown or on the centre line of the nape of the wearer's
neck. Preferably, a position marker is provided on the forward edge
of the cap (which, in use, sits on the wearer's forehead). More
preferably, the position marker is provided on the forward edge of
the cap for alignment with the centre line of the wearer's forehead
or nose. Preferably a position marker (e.g. a tactile position
marker) is alternatively or additionally provided on a side of the
cap for aligning with one of the wearer's ear. More preferably, the
cap has position markers on opposite sides of the cap (or a single
position marker extending between opposite sides of the cap) each
for aligning with a respective one of the wearer's ears.
Preferably, a said position marker for aligning with one of the
wearer's ear is designed to be aligned with a specific part of the
ear, most preferably the outer edge of the tragion of the ear.
[0026] The tactile position marker may comprise a raised element or
recessed element formed or provided on the surface of the cap. The
raised element may be, for example, a bump or a ridge (e.g. a
linear, elongated ridge). The tactile position marker can be
provided in a number of ways. For example, the tactile position
marker may be a separate element stitched or bonded to the cap, or
the tactile position marker may itself be a stitch (or a line of
stitches) having a raised profile. Alternatively, the marker may be
printed onto the fabric e.g. using a Plastisol print.
[0027] The position marker may be an integral part of the cap, in
which case it may be formed during the manufacture of the cap or
during manufacture of the materials used to create the cap.
[0028] The tactile position marker may be a linear element or it
may be an arrow-head shape with the apex of the arrow-head
designating the point to be aligned with/positioned over the
anatomical landmark e.g. with the apex of the arrow-head extending
to the forward edge of the cap for alignment of the apex with the
centre line of the wearer's forehead. This allows the wearer to
position the marker over the centre line of their forehead (by
feeling for the marker with their hands). By ensuring that the
marker is in the right place, the wearer can be assured that the
cap is correctly fitted so that comfort, water-tightness and
performance are maximised.
[0029] The visual position marker may be a visible indicator
provided on the surface of the cap. It can have any design provided
that it is obvious which part of the indicator must be aligned with
the anatomical landmark. Examples of suitable designs are:
geometric shapes such as circles, squares, triangles, diamonds
(where the centre of the geometric shape is provided as the point
for alignment over the anatomical landmark); arrow-heads (where the
apex of the arrow-head designates the point for alignment over the
anatomical landmark); crosses (where the centre of the cross marks
the point for alignment over the anatomical landmark); and lines
(which are especially useful where the marker is to be aligned with
linear anatomical landmarks). In a preferred embodiment, the visual
position marker is a line of stitches having a colour that
contrasts with a background colour of the cap. For example, the cap
may be predominantly dark in colour, and the line of stitches may
be a contrasting bright colour (or vice versa). In such an
embodiment, it is preferred that the line of stitches is also
raised so as to function as a tactile position marker.
[0030] The visual position marker can be provided in a number of
ways: it can be printed onto the surface of the cap; it can be
embroidered onto the surface of the cap; or it can be formed during
the manufacture of the fabric used to create the cap.
[0031] Advantageously, the cap may incorporate one or more position
markers to site other objects on the wearer's head, such as
swimming goggles. For example, the cap may have markers on either
side of the head to aid positioning of a swimming goggles' straps.
In addition, or as an alternative, the nose bridge of the swimming
goggles may be aligned to a position marker on a front section of
the cap. Providing one or more position markers allows the wearer
to reliably fit the goggles. A correct fit of the goggles is
necessary to ensure water-tightness and to reduce performance
impairment arising from water resistance created by incorrectly
fitting goggles.
[0032] In a cap comprising multiple panels the seams can be used as
tactile or visual position markers and aligned to anatomical
landmarks such as the nose, ears etc.
[0033] For example, the swimming cap may have a central seam
extending from the crown of the cap to a front portion of the cap
which, in use, is positioned to line-up with the centre line of the
wearer's forehead or nose. Preferably the seam is partially raised
or recessed, allowing the user to feel the seam and reliably
position the cap through reference to their forehead, without
needing to visually check whether the cap is correctly fitted.
Additionally, or alternatively, the seam may serve as a visual
position marker. For example, the seam may incorporate a line of
threads having a colour that contrasts with a background colour of
the cap.
[0034] In some embodiments, the central seam may extend from a rear
portion of the cap, over the crown, to a said front portion of the
cap. In use, this may allow a wearer to position the seam at the
front portion of the cap relative to their forehead, and the seam
at the rear portion of the cap relative to another feature, such as
the middle of the nape of the neck. Positioning the cap relative to
these two features will increase the accuracy of cap fitting.
[0035] Alternatively, or in addition to this seam, the swimming cap
may have a seam running from a side of the wearer's head to
another, opposite side of the head which, in use, is positioned to
line-up with the wearer's ears. This side-to-side seam may extend
between diametrically opposed portions of the edge of the cap
defining the opening into the cavity. Advantageously, this
side-to-side seam provides a position marker allowing quick and
easy positioning of the cap on the wearer's head. Preferably the
seam is partially raised or recessed, allowing the user to feel the
seam and reliably position the cap through reference to their ears,
without needing to visually check whether the cap is correctly
fitted. Additionally, or alternatively, the seam may serve as a
visual position marker. For example, the seam may incorporate a
line of stitches having a colour that contrasts with a background
colour of the cap.
[0036] In a preferred embodiment, the cap has both the central
seam, and the side-to-side seam, which preferably cross one another
at the crown of the cap. Using one seam to position the cap
relative to the ears and another to position the cap relative to
the forehead can result in improved cap fitting accuracy.
Alternatively, the wearer may prefer to position the cap with
reference to only one seam, therefore they have the choice of
whether to align the cap using the central seam or the side-to-side
seam.
[0037] The cap may comprise a seam running from a rear portion of
the cap to the crown of the head, the seam being offset to a side
of the head. This offset rear-to-crown seam shapes the cap at the
side of the head. Preferably, the cap comprises two offset
rear-to-crown seams.
[0038] In a preferred embodiment, the cap has the central seam, the
side-to-side seam, and two offset rear-to-crown seams. In this
embodiment, it is preferred that the central seam extends from a
rear-portion of the cap to a front portion of the cap over the
crown, and the two offset rear-to-crown seams are arranged either
side of this central seam. Additionally, it is preferred that the
rear-to-crown seams terminate at the side-to-side seam. This
arrangement of seams provides position markers for aligning the cap
relative to the centre of the forehead or nose (using the central
seam) and the ears (using the side-to-side seam).
[0039] In one embodiment of the present invention, the cap is for
use as a swimming cap liner. By "swimming cap liner" we mean a cap
which is worn under a further swimming cap. In such embodiments,
the swimming cap of the present invention may be used to arrange a
wearer's hair and subsequently overlaid with a further swimming
cap.
[0040] The wearing of two swimming caps is known, and is often
referred to as "double-capping". However, this is commonly carried
out using two silicone or latex swimming caps, which often leads
the wearer to experience discomfort. One source of discomfort may
arise from over-constriction of the head by the two elasticated
caps. A further source may be overheating resulting from the
heat-insulating effect of the silicone/latex caps.
[0041] Preferably, when the cap is for use as a swimming cap liner
it is made from a textile material. As mentioned above, caps made
from textile materials will tend to be more easily repositioned
than those made from rubber materials, because the cap grips the
head less. This allows the wearer to adjust the cap of the present
invention until an optimal arrangement of the hair is achieved, and
then overlay this with a further swimming cap. A textile material
may facilitate improved heat escape from the head, overcoming the
overheating issues common to double-capping with silicone/latex
caps.
[0042] Most preferably, when the cap is for use as a swimming cap
liner, it is made from a relatively inelastic textile material that
does not significantly compress the head. The cap can be overlaid
with a further swimming cap that compresses the head.
[0043] However, advantageously, in this arrangement the overall
compressive effect will be less than the use of two silicone/latex
caps.
[0044] When the cap is for use as a swimming cap liner, it does not
need to be made of a waterproof material. The swimming cap liner
may be made from a non-waterproof material and overlaid with a
further cap made from a waterproof material.
[0045] If the wearer wears swimming goggles, it is possible for
them to put on the swimming cap liner, then put on their goggles
before finally overlaying with a further swimming cap. This
arrangement decreases the chances of the goggles moving, for
example, when the wearer dives into the water.
[0046] To don a cap of the present invention, a swimmer first
positions the cap over their forehead, and then pulls the cap
backwards, over the head, to the nape of the neck, so that the
hanging hair remains protruding from the cap. The hair is then
stuffed into the cap, so that the hair is contained by the enlarged
volume portion at the nape of the neck.
[0047] Embodiments of the invention will now be described, by way
of example only, with reference to the accompanying drawings in
which:

DETAILED DESCRIPTION OF THE INVENTION
[0054] A prior art swimming cap 1 having a traditional shape is
shown in FIG. 1. The cap 1 fits closely to the wearer's head 2, and
terminates at the back of the head at the nape 3 of the neck.
Normally, to put the cap 1 on, a wearer will first form the hair
into a bun or similar structure at the back of the head 2, and then
stretch the cap 1 over the head 2. The position of the hair, high
at the back of the head 2, creates a bulge 4 at the back of the
head. This bulge 4 accentuates the dip created at the nape 3 of the
neck, creating dip 5, resulting in an increased recirculation of
water during swimming, creating drag.
[0055] FIG. 2 shows a swimming cap 6 according to the present
invention. The swimming cap 6 defines a cavity for accommodating
the wearer's head 2 and further defines an enlarged volume portion
7 which, in use, is positioned at the nape 3 of the wearer's neck
for containing the wearer's hair. The enlarged volume portion 7
positions the hair so as to form a low bun shape over the nape 3 of
the neck, partially filling the dip between the back of the head
and the shoulders, resulting in a dip 8.
[0056] The enlarged volume portion 7 of cap 6 positions the hair
lower on the head 2 than the prior art cap 1. The prior art cap 1
positions the hair over the parietal and occipital bones (and not
over the neck), with the substantial portion being above the
superior nuchal line and external occipital protuberance of the
skull. In contrast, the enlarged volume portion 7 of cap 6 does not
position the hair over the parietal bone, and instead positions the
substantial portion of hair over the neck, with a smaller portion
overlying the occipital bones. In cap 6 the substantial portion of
the hair is below the superior nuchal line and external occipital
protuberance of the skull.
[0057] The dip 8 at the nape 3 of the neck when using swimming cap
6 is smaller than the dip 5 when using prior art cap 1. The
arrangement of the hair created by the enlarged volume portion 7
results in improved hydrodynamics compared to prior art swimming
cap 1.
[0058] To secure the cap to a wearer's head 2, the cap includes a
gripping section. Such a cap 9 is shown in FIG. 3, which has a
continuous band of silicone rubber 10 surrounding the edge 11 of
the opening into cavity 12. In use, friction between the silicone
rubber 10 and the wearer's skin and/or hair help to secure the cap
9 to the wearer's head 2. In addition, the elasticity of the band
of silicone rubber 10 holds the cap 9 in place on the head 2 by
compression.
[0059] Advantageously, caps of the present invention are made from
multiple panels joined by seams. Such a cap 13 is shown in FIGS. 4
to 6. As with cap 9, the cap 13 incorporates a band of silicone
rubber 10 for holding the cap in place.
[0060] The cap 13 comprises a left front panel 14 and a right front
panel 15 joined by a central lapped seam 16 (with left and right
defined from the perspective of a wearer wearing the cap). The seam
16 is a lap construction, held together by stitching. The seam 16
is slightly raised from the exterior surface of the cap, to about
the thickness of the thread used to hold together the seam. This
allows the seam 16 to act as a tactile position marker for the cap
13, providing a guide to position the cap 13 on a wearer's head 2.
However, the seam is not excessively raised, as this could
negatively impact the hydrodynamics of the cap 13. In use, the
wearer may align the seam 16 with the centre of their forehead, or
their nose through feeling the position of the seam. The cap 13
also has a seam 17 running from one side of the wearer's head to
the other over the crown. The seam 17 is slightly raised from the
exterior of the cap similarly to seam 16, to act as a tactile
position marker for positioning relative to the wearer's ears. The
wearer aligns the seam 17 so as to extend from one ear to the
other. Thus, aligning seam 16 with the centre of the forehead or
nose and/or seam 17 with the ears allows a wearer to reliably site
the cap on the head. Additional seams 18 run from seam 17 to the
back of the cap 13, resulting in a right central back panel 19,
right side back panel 20, left back central panel 21 and left side
back panel 22.
[0061] The rear of the cap 13 has a smooth gradient profile i.e.
there are no significant deflections which would be undesirable as
they would result in increased drag.
[0062] Seam 16 incorporates a line of stitches 23 having a colour
contrasting with the background colour of the cap. Seam 17
incorporates a similar line of stitches 24. The stitches are used
as visual position markers, for aligning to the same anatomical
landmarks as their corresponding seams. In this instance, the
stitches form a part of the seam structure. However, in other
embodiments the cap can incorporate a line of stitches for acting
as a visual or tactile position marker that are not integral to the
seam structure.
[0063] The skilled person will appreciate that the swimming caps
illustrated in the figures and described above are examples
embodying inventive concepts described herein and that many and
various modifications can be made without departing from the
invention.
