Application No. PCT/AU2016/000194 claims priority to Australian
Patent Application No. 2015902144, filed Jun. 9, 2015. The entire
contents of each of the above-referenced applications are
incorporated by reference in their entirety for all purposes.
FIELD OF INVENTION
[0002] The present invention relates to the field of pillows or
cushions.
[0003] In one form, the invention relates to a portable cushion for
supporting a user's head, neck, shoulders or upper body to enable
comfortable resting or sleeping when the user is sitting in an
upright or forward position.
[0004] It will be convenient to hereinafter describe the present
invention in relation to a seated user who is travelling by air,
road, or rail, however, it should be appreciated that the present
invention is not limited to that use only. The present invention
also has a wide range of applications wherein the user is
stationary. By way of example the present invention could be used
in a medical application where a patient is required to sit still
in a relatively forward upright position while a procedure is being
carried out, or because they have a condition that makes lying down
inadvisable.
[0005] It will be further convenient to hereinafter describe the
present invention as a support considering that such support is
cushioned or configured to provide comfortable surfaces to engage
with the travellers head or other part of their body. The support
is portable however it may also be removably attachable to a
further supporting non-portable device or structure such as a
seat.
BACKGROUND ART
[0006] It is to be appreciated that any discussion or documents,
devices, acts or knowledge in this specification is included to
explain the context of the present invention. Further, the
discussion throughout this specification comes about due to the
realization of the inventor or the identification of certain
related art problems by the inventor. Moreover, any discussion of
material such as documents, devices, acts or knowledge in this
specification is included to explain the context of the invention
in terms of the inventor's knowledge and experience and,
accordingly, any such discussion should not be taken as an
admission that any of the material forms part of the prior art base
or the common general knowledge in the relevant art in Australia,
or elsewhere, on or before the priority date of the disclosure and
claims herein.
[0007] Many travellers are required to sit upright for long periods
of time. Due to seating arrangements and space constraints they are
unable to lay horizontal or near horizontal to facilitate
comfortable sleeping. Often this results in tiredness, pain and
discomfort with a negative effect on the traveller's health and
wellbeing.
[0008] Similarly, the nature and environment of travel provides
vibration, bumps, noise and other interruptions to rest or sleep
that are not usually experienced in a resting or sleeping
environment. In an effort to gain extra comfort, travellers
typically use U shaped pillows or adjustable flaps built into an
airline seat to support the head from falling left, right or to the
rear. However these devices rely on the head and body to be
oriented rearward, resting on the seat back, and they do not stop
the head from falling forwards.
[0009] In an attempt to find a comfortable position when seated, an
airline traveller may try leaning forward and bracing their head in
their hands. This is not sustainable as the arms relax as the
traveller falls asleep and the brace collapses. Similarly a
traveller may rest their head on a stack of pillows or other
makeshift support items on an outwardly folded tray table, however
this position may not be particularly comfortable for a sustainable
period. Some devices, such as the device described in U.S. Patent
Application No. 2003/0167571, provide a support that rests upon a
tray table extending from the back of an airline seat so that a
traveller may sit in a relatively forward upright position. However
these types of devices are often unsuitable in confined spaces,
such as the economy section of an aircraft, because they are large
in volume and cumbersome. Furthermore, devices of the prior art
that require support from the tray table fixed to the seat of a
passenger in front typically move if the passenger in front moves.
This tends to disturb the traveller using the support.
[0010] Sustaining a seated position for extended periods is not
only uncomfortable but can cause neck injuries or soreness to the
traveller. In particular, sleep or comfortable rest can be
difficult to achieve in aircraft when a traveller is required to
sit in a relatively upright position in an environment that is
noisy, vibrating and punctuated by disturbances due to aircraft
movement and the activities of passengers or crew.
[0011] Given the nature of upright and seated travel, travellers
may also take sleeping pills or similar. Such drugs may cause
drowsiness or other unwanted side effects. In the case of an
emergency, such drowsiness or side effects may limit the
traveller's ability to react appropriately to avoid injury or life
threatening situations.
[0012] In addition, travellers often use miscellaneous aids such as
headphones, ear plugs, eye masks and other items. Travellers often
pack such aids into carry-on baggage that is stored in overhead
lockers or under their seat making them inconvenient to access.
Furthermore, the aids often become lost, disorganized or are simply
inconvenient to carry.
SUMMARY OF INVENTION
[0013] An object of the present invention is to provide a device
that improves sleep or rest in the seated position.
[0014] Another object of the present invention is to provide a
means for improved sleep or rest for road, rail or air
travellers.
[0015] It is an object of the embodiments described herein to
overcome or alleviate at least one of the above noted drawbacks of
related art or to at least provide a useful alternative to related
art.
[0016] In a first aspect of embodiments described herein there is
provided a support comprising: a first pillow comprising a first
pillow body having a first arm and a second arm, a second pillow
comprising a second pillow body having a third arm and a fourth
arm, the first and third arms being attached to a first joint, and
the second and fourth arms being attached to a second joint wherein
the first and second pillows can be rotated about the joints.
[0017] The first pillow and second pillow may be discretely
connected or integral at the joints but must be able to be rotated
about the joints by bending (if integral), or by virtue of
inclusion of a hinge or other rotatable mechanism. When the first
pillow and second pillow are integral the first joint and the
second joint may be, for example flex points wherein the degree of
rotation around the joints can be adjusted and releasably locked
using a locking mechanism.
[0018] Typically each of the first pillow and the second pillow has
an internal surface and an external surface. The support has a
first, fully `closed` position in which the two internal surfaces
are pressed together and are in contact over most of their surface
area. The support also has a second fully `open` position in which
the two internal surfaces, i.e. the bottom of the top pillow and
the top of the bottom pillow are not in contact. The support can be
changed between the fully open and fully closed positions by
rotation about the joints.
[0019] In use, at least one of the external surfaces is in contact
with the user's body, typically their face, if they are at
rest.
[0020] In one embodiment of the present invention the first pillow
and second pillow are of complementary size and shape. In another
embodiment of the present invention the first pillow and the second
pillow are of different sizes or shapes. For example, one pillow
could be conformed to fit within a recess in the other pillow.
[0021] The pillows may be made of any material suitable for bearing
the weight of a person at rest, and in some aspects may be subject
to the user's personal preference with regard to pillow softness
and density. In a particularly preferred embodiment the pillows are
made of expanded polymeric foam, such as memory foam, expanded
styrene beads or foam pieces. Alternatively the pillows may be
inflatable. The pillow may be constructed of any number or
combination of materials. For example, the pillows may have
relatively soft or low density material encapsulating a higher
density material that is configured to give shape and structural
support to the pillow. In some examples, at least one higher
density material forms all or part of an internal frame.
[0022] The pillows may be filled with the same or different
materials in the same or different densities and have the same or
different amounts of surface curvature. For example, in some
embodiments, the surface of one pillow may curve more than the
other pillow, or they may have complementary curvature. In one
aspect, the lower pillow may be contoured such that when the
support is closed, the two pillows are flush with each other, such
that the top of the lower pillow fits into contours in the bottom
of the upper pillow. In other embodiments, the pillows may be
mirror images of each other. In an additional embodiment, the top
of the bottom pillow and the bottom of the top pillow may be
planar. In further embodiments, the top surface of the first pillow
may be more curved than the bottom surface of the bottom pillow. In
another aspect, the top surface of the upper pillow and the bottom
surface of the bottom or second pillow may have regular or variable
amounts of contouring to support various aspects of the body. For
example, the upper surface of the top pillow may be shaped to fit
the planes of the face, providing raised areas or lowered areas
following the standard outline of a face. In other aspects, the
bottom surface of the first pillow and the top surface of the
bottom pillow may be shaped to better support arms placed between
the pillows. The top and bottom surfaces of a pillow may have the
same amount of curvature, have different amounts of curvature, be
mirror images of one another, have different or opposite amounts of
concavity, i.e. one may be convex while the other is concave, have
complementary or contrasting amounts of curvature, i.e. one may be
planar while the other is more curved, or any combination
thereof.
[0023] One or both pillows may comprise a rigid structural support
located internally or externally to the pillows. In a particularly
preferred embodiment, the rigid structural support is internal to
one or both pillows and is generally U-shaped with each end located
adjacent one of the joints.
[0024] In a particularly preferred embodiment the first pillow and
the second pillow are U-shaped but the pillow shapes may vary for
purposes such as styling, additional comfort, or for better
spreading of any load imparted to the pillows by the weight of a
user.
[0025] In the second aspect of embodiments described herein there
is provided a support comprising: a first pillow comprising a
U-shaped pillow body having a first arm and a second arm, a second
pillow comprising a U-shaped pillow body having a third arm and a
fourth arm, the first and third arms being attached to a first
joint, and the second and forth arms being attached to a second
joint, wherein the first and second pillows can be rotated about
the joints and configured to receive the front of user's neck
between the first and second arms and the user's head can rest in a
forward position on the first pillow body.
[0026] In this manner the user can rest their head in a forward
position, the pillow comfortably resting the weight of the user's
head without them being required to provide assistance with their
arms, hands or any other part of their person.
[0027] The support can be adjusted to support the travellers head
as it tilts to the left, right, rear or forward position or any
position in between.
Pillows
[0028] The shape and configuration of the support can provide clear
space for the traveller to breathe when head rests on the first
pillow, their face being located in the U-shaped void defined by
the pillows leaving the user's nose and mouth unobstructed.
[0029] As such, the support of the present invention has multiple
modes of use some of which are described and depicted herein. These
modes are possible by virtue of the support enabling a user to
better use the space available in and around their seat in order to
find their most optimum comfort position. Travel pillows of the
prior art do not offer as many different options.
Harness
[0030] In another preferred embodiment, the support includes a
harness. Typically the harness is in the form of a strap of
adjustable length having ends adapted for removable attachment to
the support. For example the adjustable strap may be attached by
buckles or Velcro adjacent the joints.
[0031] It will be readily apparent to the relevantly skilled person
that it would be optimum to have a seat configured for ready
attachment to the pillows or the harness.
[0032] The harness may be used in several ways. For example, the
harness may be used to retain the support around the user's seat
back or neck so that it does not fall when the weight of the
travellers head is lifted from the support. Alternatively, the
harness may be used as a shoulder or neck strap for carrying the
support when not in use and leaving the user's hands free for
carrying luggage and for other tasks.
Joints--Rotation
[0033] The first joint and second joint may be integral with one or
both pillows. Alternatively the joints may be removably attached to
one or both pillows.
[0034] Preferably the joints are configured to allow the angle
between the first pillow and second pillow to be adjusted and then
releasably locked in a desired position. For example, the support
may include a releasable locking mechanism so that the degree of
rotation of the first pillow and second pillow about the joint can
be releasably maintained. The ability to lock the pillows into
position is particularly useful for providing support to the user's
head and body in a forward upright or rearward upright position
when the user is seated.
[0035] In one embodiment the joint is rotatably adjusted using a
ratchet mechanism or screw thread mechanism. In another embodiment
the joint is spring loaded and self locking.
Joints--Extension
[0036] In a preferred embodiment each joint is extendable. In a
particularly preferred embodiment each joint comprises a hinge with
one, two or more extendable leaves. For example, one or two leaves
may be in slidable arrangement with a frame that can be extended
from the leaf and then retracted relative to the leaf.
[0037] Each leaf and any associated frame may, independently, be
embedded within a pillow, or adjacent an external surface of a
pillow. Preferably the frame, or frame in combination with the
leaf, is capable of providing structural strength to the support
and is capable of bearing some of the load imparted on the
pillows.
[0038] Preferably the joints are configured to allow the extension
or retraction of the joint to be adjusted and then releasably
locked in a desired position. For example the support may include a
releasable spring loaded locking mechanism.
[0039] Thus in a third aspect of embodiments described herein there
is provided a support comprising: a first pillow comprising
generally U-shaped body portion having a first arm and a second
arm, a second pillow comprising a generally U-shaped body portion
having a third arm and a fourth arm, the first and third arms being
attached to a first joint, and the second and forth arms being
attached to a second joint, wherein the first joint and the second
joint are extendable.
[0040] The extendable leaves allow the pillows to be moved apart,
varying the distance between them at least in the vicinity of the
joints. Thus the user has the ability to (i) vary the degree of
rotation of the pillows around the joints, and (ii) vary the
separation between the pillows in the vicinity of the joints. This
provides a user with myriad options for positioning the pillows and
supporting their upper body.
Storage
[0041] In another preferred embodiment the support is adapted to
provide storage for example for the harness or a removable joint.
For example a storage area may be provided as a recess in one or
both pillows. The recess may be formed of or lined with a material
that holds its contents in place, or may be formed of or covered
with the same or a different material as the material covering the
support, with a closure mechanism allowing the recess to be opened
and shut as desired. In some aspects, the recess is of an
appropriate size to permit the placement of objects in the recess
without interfering in the closing of the support such the first
pillow and the second pillow are substantially flush with one
another. For example, the recess may be sufficient to allow the
bottom of the first pillow and the top of the second pillow to be
pressed together and in contact over most of their surface area
without interference from the items in the recess. In one aspect,
the bottom of the first pillow and the top of the second pillow may
be contoured to accommodate the presence of objects in the recess
without interfering with the closing of the support and/or the
contact between the first and second pillow. In other embodiments,
the bottom of the first pillow and the top of the second pillow may
be substantially planar with the recess of sufficient depth to
allow for the insertion of items without disrupting the closure of
the device.
[0042] Alternatively the storage recess may be in the form of a
pocket or other receptacle that is integral, or removably attached
to the support. The storage recess typically includes a suitable
closure such as a zipper or flap secured by Velcro. In some
aspects, the bottom of the first pillow and the top of the second
pillow may be contoured to allow for the presence of objects in the
storage recess and still permit the support to fully close.
Modes of Use
[0043] There are multiple modes of use of the support of the
present invention which will be apparent from the description and
drawings herein.
[0044] In a fourth aspect of embodiments described herein there is
provided a method of using a support, the support comprising: a
generally U-shaped first pillow having a first arm and a second arm
extending from a first pillow body, a generally U-shaped second
pillow having a third arm and a fourth arm extending from a second
pillow body, the first and third arms being attached to an
extendable first joint, and the second and forth arms being
attached to an extendable second joint, wherein the method
comprises the steps of: rotating the first and second pillows about
the joints, optionally extending the first and second joints,
locating the front of user's neck between the first arm and second
arm so that a user's head can rest in a forward position on the
first pillow body, and locating the second pillow on a surface to
support the weight of the user's head.
[0045] The weight of the user's head resting in a forward position
on the first pillow body can thus be dispersed to the second pillow
and then onto the surface on which it rests, such as the user's
shoulder, user's torso, horizontal surface such as a table top or
chair arm, vertical surface such as a wall.
[0046] The method of use may further comprise the step of
connecting a harness between the support and the user, or structure
for bearing part of the load.
[0047] Other aspects and preferred forms are disclosed in the
specification and/or defined in the appended claims, forming a part
of the description of the invention.
[0048] In essence, embodiments of the present invention stem from
the realization that a travel pillow can be configured to better
support the weight of a user's head when they are confined in an
upright sitting position for extended periods of time. The
configuration of the travel pillow can be angled or extended to
provide more options for the user to comfortably orient themselves
in a forward sitting position within a limited space such as an
airline seat.
[0049] Advantages provided by the support of the present invention
comprises the following: ability to support the head, neck and
first body in a relatively forward position when sitting; can be
used in a multitude of travel applications in aircraft, trains,
buses, cars, boats, in addition to other non-travel related
applications such as sitting at an office desk, or during medical
procedures where patients are required to have their body upright,
or any other situation requiring an upright sitting position; is
portable and can remain comfortably placed around the neck while a
user is walking, such as between transit services, thus providing
free hands to carry other items; may be attached to a secondary
non-portable device or structure to provide additional support to
the user; provides an additional and improved level of comfort and
increases the user's likelihood of gaining sleep when compared to
devices of the prior art designed for this said purpose; allows a
user to make the best use possible of the space around them, even
very confined space, by enabling them to bend forward, or to either
side; may be worn by the traveler and therefore not considered to
be carry-on or check-in luggage; provides all the advantages of a
conventional U shape pillow of the prior art; can be used to carry,
organize and store various accessory & travel related
items.

DETAILED DESCRIPTION
[0075] Embodiments disclosed herein provide a portable support for
a user's head and neck which can be used in multiple modes.
[0076] In a particularly preferred mode, the user's head and neck
are supported. This first mode of operation is not dissimilar to a
conventional travel pillow whereby the traveller positions the
support on the shoulders and around the neck.
[0077] In another preferred mode, the user's head, neck, shoulders
and upper body are supported. This second mode of operation enables
the user to open the two pillows of the support to an angle which
provides a comfortable resting or sleeping position whereby the
user's face, head, neck, shoulders and upper body are supported
relatively forward of the upright seated position thus providing a
comfortable position for sleep or rest.
[0078] FIG. 1 depicts a side view of one embodiment of the support
8 of the present invention suitable for portable use during travel.
In this view, the support 8 is in the closed position with the
inner surface 1a & 7a of each pillow 1 & 7 in abutting
relationship. The pillows 1 & 7 are connected by jointed hinges
4a & 4b which are tightened and locked by rotating either or
both of the knobs 5a or 5b. In the closed position, the support 8
is compact and portable and readily stored or carried.
[0079] In the embodiment shown in FIG. 1, the first pillow 1 and
second pillow 7 are of the same shape and dimensions though in
alternate embodiments, the first pillow 1 and the second pillow 7
may be different sizes. It can readily be seen that each pillow has
a body and two arms. The end of each arm terminates at the hinge 4,
thus connecting the two pillows 1 & 7. The arms of each pillow
join at the point farthest from the pillow to form a U-shape. That
is, the first and second arms of the first pillow join to form a U
shape at the point farthest from the hinges where they connect to
the second pillow and the third and fourth arms of the second
pillow join to form a U shape at the point farthest from the hinges
where they connect to the first pillow. While the first pillow 1
and the second pillow 7 are shown as having planar inner surfaces
and rounded outer surfaces, other shapes may also be used. For
example, in some embodiments, the top surface of the bottom pillow
7 may be contoured. Such a contoured shape may fit the bottom
surface of the top pillow 1, such that when the support 8 is in a
closed position, the first pillow 1 and the second pillow 7 are
substantially flush. In some aspects, contouring may be such that
when viewed from the side as in FIG. 1, the contouring on the
bottom of the first pillow and top of the second pillow are is not
visible. In other aspects, the contouring may be such that when in
a closed position, the bottom of the first pillow 1 and the top of
the second pillow 7 are pressed together and are in contact over
most of their surface area. Contouring may also be useful, for
example, in certain modes of the invention, such as when the arms
of the user are placed between the two pillows or for cosmetic
purposes.
[0080] The top surface of the first pillow 1 and the bottom surface
of the second pillow 7 may have the same or different shapes. In
some examples, they may both be slightly rounded as shown in FIG.
1. In other embodiments, the bottom surface of the second pillow 7
may be substantially planar to fit comfortably against the chest.
In another aspect, the top or exposed surface of the first pillow
may be more rounded or contoured than the bottom surface of the
second pillow to provide better support for a face. For example,
the top surface of the first pillow 1 may slope towards the center
opening of the first pillow. In additional embodiments, the top
surface of the first pillow may be thicker or more convex where the
arms join, thinning through the curve of the arms and then
thickening again as the arms approach the hinges connecting the
first and second pillow. For example, the top surface may be convex
at the join of the arms at the point furthest from the pillows
where the first arm and the second arm come together to form the U
shape of the pillow, concave at the midpoint of the arms and then
convex at the lower third of the arms approaching the hinges. In an
additional embodiment, the top surface of the first pillow may be
thicker, or more raised at the point where the first arm joins the
second arm and/or the third arm joins the fourth arm, decreasing in
thickness as the arms approach the terminal hinges. In a further
embodiment, the arms of one or both of the pillows increase in
thickness as they approach the hinges. Such thickness may be evenly
distributed on the upper and lower surfaces of one or both of the
pillows, or may be predominantly on one surface or another. For
example, in some embodiments, the upper surface of the first pillow
may be thicker as the arms approach the hinge, while the bottom
surface of the first pillow is substantially planar or contoured to
receive the top surface of the second pillow. Top and bottom
surfaces of the two pillows may be independently contoured, planar,
both contoured, both planar, or any combination thereof. Further,
the shape of each pillow and the shape of the top and bottom
surfaces of each pillow may be determined independently of the
other pillow, i.e. the first pillow may have a contoured top
surface and a substantially planar bottom surface and the second
pillow may have a substantially planar top surface and a contoured
bottom surface or any combination thereof.
[0081] FIG. 2 depicts the support 8 of FIG. 1 from the front. In
this view the first pillow 1 can be readily seen, and obscures from
view the second pillow 7 which is directly behind. The pillows 1
& 7 in this embodiment are generally U-shaped and define a
space 2 for receiving a travellers face, head and neck. The hinges
4a & 4b are folded and locked so that in this view the support
8 is maintained in the closed position. Each hinge 4a & 4b has
two leaves 10a, 10b, 10c & 10d (10a & 10b associated with
the first pillow 1; 10c & 10d associated with the second pillow
7). Each of knobs 5a & 5b can be rotated in a first direction
to lock the hinge to which they are respectively attached.
[0082] When the knobs 5a & 5b are rotated in a counter
direction the restriction on their respective hinges 4a & 4b is
reduced and the angle between the pillows 1 & 7 can be adjusted
according to the desired support position of the traveller. In this
embodiment the frames 9a & 9b can be extended from the leaves
10a & 10b of the joint hinges 4a & 4b.
[0083] The U-shape 3 formed by the pillows 1 & 7 allows the
user to position the support 8 on their neck and wear the support 8
as they board or disembark from an aeroplane, train or bus or when
they are in transit, as well as providing head and neck support
while seated relatively upright.
[0084] FIG. 3 is a side view of the support 8 in the open position.
In this view the hinges of the joints 4 have been rotated, moving
the pillows 1 & 7 to a 180 degree angle of separation at the
joints 4a & 4b as compared with the closed position shown in
FIG. 1. The hinges of the joints 4a & 4b have been adjusted by
rotating their respective knobs 5a & 5b as described with
reference to FIG. 2.
[0085] FIG. 3B is a side view of the support 8 in the open position
with a recess 65 in the first pillow 1. The recess or storage space
65 may be used for the storage of any miscellaneous item, however
typically it is used for the storage of travel related items,
headphones, ear plugs, eye mask, pen, batteries and the like. While
the recess 65 is shown as being open to the environment, it may
alternatively have a covering with or without a closure mechanism.
As shown in FIG. 3B, the presence of such a storage space 65 does
not interfere with the closure of the support 8. Thus, when
miscellaneous items are stored in the recess or storage space 65,
closure of the support 8 will have a profile substantially similar
to the profile shown in 1. Alternatively, the bottom surface of
pillow 1 and the top surface of pillow 7 may be contoured to
accommodate the presence of miscellaneous objects in the recess or
storage space 65 without interfering with the closing of the
support 8 so that the pillows 1 and 7 are substantially flush with
one another in which when the bottom of the first pillow and the
top of the bottom pillow are pressed together they are in contact
over most of their surface area.
[0086] FIG. 4 is a front view of the support 8 as shown in FIG. 3.
In this view the hinges of the joints 4a & 4b are both visible.
Each joint hinge has a leaf 10a & 10b, each of which has an
extendable frame 9a & 9b which in this view is shown adjacent
an internal surface of the first pillow 1. The extendable frames 9a
& 9b are inside the pillow and therefore cannot be seen. In
other embodiments of the support however, other arrangements of the
hinge leaves and extendable frames may be used, such as having all
leaves and frames located inside the pillows, or all located on
surfaces of the pillows, or a combination of the two. The buttons
6a & 6b are configured to engage with the leaves 10a & 10b
to actuate extension or locking of the frames 9a & 9b. FIG. 4
depicts the frames 9a & 9b in the fully retracted position
which brings the pillows 1 & 7 together in abutting
relationship and the ends of their arms.
[0087] FIG. 5 depicts a side view of the support 8 with two pillows
1 & 7 with the joints 4a & 4b adjusted with their
respective pairs of leaves 10a & 10c and 10b & 10d at 90
degrees. The frames 9a & 9b of leaves 10a & 10b have been
extended following pressing of the buttons 6a & 6b of the
actuators, sliding along their respective hinge leaves 10a &
10b so that a user can achieve any desired position between full
extension or full retraction of the frames 9a & 9b.
[0088] FIG. 6 depicts a front view of the support 8 with the two
pillows 1 & 7 and the pairs of joint leaves 10a & 10c and
10b & 10d adjusted to a straight angle of 180 degrees. This
embodiment depicts the joint leaves 10c & 10d located fully
inside the second pillow 7 while the leaves 10 & 10 b are
exposed with the frames 9a & 9b extended. Actuation of the
knobs 5a & 5b, and buttons 6a & 6b may be required to
adjust the respective frames 9a & 9b and hinges 4a & 4b as
previously described.
[0089] This embodiment of the support further depicts a storage
space 11 with a closure 12. The storage space 11 may be used for
any miscellaneous item however typically it is used for the storage
of travel related items, headphones, ear plugs, eye mask, pen,
batteries and the like.
[0090] FIG. 7 depicts a side view and FIG. 10 is a perspective view
of the first mode of use of the support 8. In the first mode the
two pillows 1 & 7 are closed against each other with their
inner surfaces (1b, 7b) pressed together. The support 8 is located
around the neck of the seated user 14 in a position typical of a
conventional U shaped travel pillow. The traveller 14 is able to
shift their position to rest their head 15 against the support 8 or
the seat 19. In this mode the user 14 does not have support for the
head 15 if the weight of the head 15 shifts forward away from the
seat 19 because the U-shaped opening 3 defined by the pillows 1
& 7 provides no support in that area.
[0091] FIG. 11 depicts a second mode of use wherein the support 8
is more open with the joint 4 locked to maintain an acute angle
between the two pillows 1 & 7. The user can rotate the support
around their neck to the desired position, resting the pillows on
the seat. This position provides a significant improvement over a
regular U shaped neck pillow. In some aspects, the users head is
supported higher up, in a straighter or more elevated position than
can be achieved with a standard U shaped neck pillow, transferring
the weight away from the neck and distributing the weight to the
user's shoulders and providing a larger surface area for support.
Such an embodiment, redistributes the weight of the head and
alleviates strain on the neck, allowing for a more comfortable
resting position. A regular U shaped neck pillow provides a hinge
point at the users neck whereas the position of FIG. 11 evenly
distributes the weight of the user's head over a larger area, away
from the neck, to the shoulders. The seatback and the internal
frame of the two pillows combined with the lockable hinges also
provides support in this mode.
[0092] FIG. 12 depicts a third mode of use in which the two pillows
1 & 7 are opened and the joint 4 is locked to form an acute
angle about the joints 4a & 4b. The second pillow can be rested
on a flat surface such as a bench or tray table extending from the
rear of an aeroplane seat. Typically the user will place their
forearms between the first and second pillow.
[0093] FIG. 8 depicts a fourth mode of operation of the support 8
in a side view. FIG. 13 is a perspective view of the fourth mode of
operation of the support 8. In this mode the two pillows 1 & 7
are in an open position. In this mode the user has their head 15
against the outer surface la or the first pillow 1 and their chest
against the outer surface of the second pillow 7. The weight of the
travellers head, neck and upper body is downwardly pressing against
the pillow 1 in which the frames 9a, 9b may optionally be extended
from the joint leaves 10 (not visible) providing a comfortable
sleeping or resting position. Extending the frames may be
particularly desirable, for example, for very tall users. The
weight is also transferred to the user's 14 chest and second body
through the frames 9a, 9b. In this embodiment an adjustable strap
13 is located around the neck of the user 14 and attached adjacent
the joints 4a, 4b of the support 8 thus preventing the support 8
from falling downward if the user 14 lifts their head 15 or shifts
their body position. The support 8 may also be rested against the
seat arm 16 or in further embodiments a secondary frame (not drawn)
may extend from the support 8 to provide a further brace which may
rest or be affixed to the seat arm 16, seat 9 or any other
conveniently located fixed structure.
[0094] FIG. 9 depicts a front partial view of the support 8 with
the user's face 20 resting against the second pillow 7. In this
embodiment, the U-shape 3 defined by the pillows of the support 8
enables the weight of the user's head to be dispersed through the
support 8 whilst the space 2 defined by the pillows leaves the face
20 unrestricted so the user can breathe through their nose 17 and
mouth 18 leaving the chin 67 supported on the sides but otherwise
unobstructed. In this view the support is only partially shown and
the second half 21 of the support 8 has been omitted. The support 8
herein is positioned against the user in the same manner as
described in FIG. 8 whereby the travellers said weight is dispersed
to the traveller's chest and lower body.
[0095] FIG. 14 depicts a fifth mode of use of the support 8 wherein
the adjustable strap 13 is looped around a seat headrest or
otherwise attached to the seat. The ends of the strap are attached
adjacent the joints 4 of the support 8, again preventing the
support 8 from falling downward if the user 14 lifts their head 15
or shifts their body position. In this mode the user rests their
face in the U-shaped recess.
[0096] FIG. 15 depicts a sixth mode of use of the support 8, which
is similar to the fifth mode, except that the user rests with one
cheek on the first pillow.
[0097] The fifth and sixth modes allow the user to lean forward in
a manner similar to propping their head with their hands. When used
in aeroplanes, these modes provide the advantage that the person in
front can angle their seat backwards without interfering with use
of the support. Furthermore the user does not need to incline their
own seat.
[0098] In a seventh mode the user loops the adjustable strap around
a seat headrest, opens the pillows to form an obtuse angle at the
joints and orients the support to their left or right side so the
user sleeps upright with their back to the seat but with all their
weight leaning sideways.
[0099] There are multiple other modes of use of the support of the
present invention which will be readily apparent to the user and
which will fall within the scope of the present application.
[0100] FIG. 16 depicts one embodiment of a joint according to the
present invention. In this embodiment the joint can lengthen and
shorten the distance between the pillows by virtue of a sliding
ratchet mechanism which can be operated manually by pulling the
pillows away or pushing the pillows toward each other. The ratchet
comprises a tubular configuration of the leaf 10a which receives
the frame 9a. The frame 9a has two integral legs sprung outwardly
with a dome shaped end (not visible) that engages with the recesses
28 to lock the selected distance position.
[0101] Furthermore as depicted in FIG. 17, in some embodiments the
joint can be rotated by depressing the knob 23 which is connected
to a splined shaft 31 which slides through an orifice 22 (shown in
FIG. 16) and pushes the frame 9a to disengage the pins 29 which
slide into any of the multiple recesses 30 located in the frame 9a.
When the knob 23 is released, the spring 24 pushes the frame 9a
toward the pin and as the joint is rotated the pins 29 slide back
into the recesses 30 to lock the desired angle of the frames 9a and
9b relative to each other and thus setting the angle of the pillows
1 & 7. In some examples, a depressable locking tab 25 may
prevent frame 9a from being separated from leaf 10a. Depression of
the locking tab 25 releases the frame 9a, guiding the extension or
retraction from slot 26 allowing the user to change the distance
between the first pillow 1 and a second pillow 7. In some aspects,
the depression of the locking tab 25 allows for the first pillow 1
and second pillow 7 to be separated into two individual pieces,
such as for cleaning purposes. A similar mechanism may be found on
the opposite side, with a corresponding depressable locking tab
assisting in the interaction with the frame 9b and the leaf
10b.
[0102] In one aspect, a support 8 comprises a first pillow 1 and a
second pillow 7. Either or both pillows may comprise an internal
support structure. While such a support structure may be made of
any material generally used, in some embodiments such an internal
support structure may be made of a higher density material than the
surrounding material of the pillows. In some examples, this
internal support structure provides structural support to each of
the pillows 1 & 7. Referring to FIG. 18, a first pillow 1 and a
second pillow 7 are shown in a closed position as seen in an
alternate embodiment in FIG. 2. The first pillow 1, shown in a
solid line, has an internal support structure 64, shown in a
dash-dot pattern of lines. Such an internal support structure 64
may be in one or both pillows of the support 8. The second pillow 7
is shown by a dashed line as it would not be visible from the front
when the support 8 is in the closed position.
[0103] In some aspects, each pillow has two arms which terminate at
a hinge joint 4 (not shown in FIG. 18), thus connecting the two
pillows 1 & 7. As shown in FIG. 18, the support may comprise a
rigid or semi-rigid support structure 64. In some aspects the
support structure may abut or connect to extendable frame 9a and 9b
(shown in a combination of long and short dashes). In other
aspects, the rigid support structure 64 is part of the extendable
frame 9a and 9b. In additional embodiments, the extendable frames
9a and 9b and the rigid or semi-rigid support structure 64 form one
piece that forms a U shape, or otherwise follows the shape of the
pillow bodies. The extendable frames and/or the rigid or semi-rigid
support structure may be manipulated using buttons or knobs such as
those described in reference to FIG. 2.
[0104] As shown in FIG. 19, which depicts an underside view of a
support 32 in a closed position, in one example, the support 32 may
comprise a first pillow 34 and a second pillow 36. The first pillow
34 may comprise a first arm 40 and a second arm 42 forming a first
opening 44 with space for receiving a traveller's face, head and
neck. In some aspects, the first pillow 34 and second pillow 36 may
be connected by hinges which can be actuated using knobs 56a and b
and/or buttons 54a & b. In some aspects, the first opening 44
may be U-shaped. In other aspects, the exterior perimeter of the
pillows may be U-shaped. The two pillows may be connected at hinges
46 and the positions of the two pillows relative to one another may
be manipulated by actuating the knobs 56a & 56b, and/or buttons
54a & 54b to adjust the respective frames 52a & 52b shown
in FIG. 22 and as previously described above in reference to knobs
5a and 5b and buttons 6a and 6b.
[0105] FIG. 20 illustrates a top down view of the support 32 of
FIG. 19 with only the first pillow 34 showing. As seen in FIG. 19,
the first pillow 34 has a first arm 40 and a second arm 42, with
the first arm 40 and the second arm 42 joined at the point furthest
from joint hinges 46 and 48 to form a U shape. Actuation of the
knobs 56a & 56b, and/or buttons 54a & 54b may be required
to adjust the respective frames 52a & 52b shown in FIGS. 22 and
23 and hinges 46 & 48 as previously described above in
reference to knobs 5a and 5b and buttons 6a and 6b. The knobs and
buttons may be located at any useful location in any suitable
configuration. For example, they may be located with both the
buttons and the knobs on the exterior edge of the support 32 and/or
hinges as shown in FIG. 19, with the buttons near the interior edge
of the support 32 and the knobs on the exterior edge of the support
and/or hinges as shown in FIG. 20, or with both the buttons and the
knobs on the interior edge of the support and/or hinges as shown in
FIG. 23, or any combination thereof.
[0106] The first pillow 34 and the second pillow 36 may be the same
or different sizes. In some aspects, the second pillow 36 is
designed to fit in a recess 38 within the first pillow 34. Thus,
when viewed from the side in the closed position, all or part of
the second pillow 36 is hidden from view as shown by the dotted
lines in FIGS. 21A and 21B. The first pillow 34 and the second
pillow 36 may have the same or different perimeter profiles. When
in the closed position as shown in FIGS. 20 and 21, the support 32
functions as a regular neck pillow and can be worn around the neck
for both comfort and transport of the support. In further
embodiments, when in the closed position, the support 32 can easily
be transported, for example, it may be carried as part of a
traveller's carry-on allotment.
[0107] As shown in FIG. 21B, in some aspects, one or both of the
pillows may have a recess 66 (shown in the first pillow in FIG.
21B). The recess or storage space 66 may be used for the storage of
any miscellaneous item however typically it is used for the storage
of travel related items, headphones, ear plugs, eye mask, pen,
batteries and the like. While the recess 66 is shown as being open
to the environment, it may alternatively have a covering with or
without a closure mechanism. As shown in FIG. 21B, the presence of
such a storage space 66 does not interfere with the closure of the
support 32 to the closed position. In some aspects, the bottom
surface of pillow 1 and the top surface of pillow 7 may be
contoured to accommodate the presence of miscellaneous objects in
the recess or storage space 66 without interfering with the closing
of the support 32. In some aspects, when closed, the pillows 1 and
2 are substantially flush with one another such that when the
bottom of the first pillow and the top of the second pillow are
pressed together they are in contact over most of their surface
area.
[0108] FIG. 22 is an open view of the support 32 with joint hinges
46 and 48. The second pillow 36 has a third arm 58 and a fourth arm
60 forming a second opening 62 with space for receiving a
traveller's neck in the modes shown in FIGS. 10 and 11. In some
aspects, the second opening 62 may be U-shaped, with the third arm
58 and the fourth arm 60 joining at the point farthest from joint
hinges 46 and 48 to form the U-shape. Each joint hinge 46 or 48 has
a leaf 50 a & 50 b (not shown), each of which has an extendable
frame 52a & 52b respectively, which in this view is shown as
dotted lines indicating that the extendable frame is internal to
the first pillow 34 and cannot be seen from the outside. The first
pillow 34 has a space 44 for receiving a traveller's face in a
further mode as depicted in FIG. 14 wherein the first pillow 1 is
considered to provide the same function as the first pillow 34 of
FIG. 21. In other embodiments of the support, however, other
arrangements of the hinge leaves and extendable frames may be used,
such as having all leaves and frames located inside the pillows, or
all located on surfaces of the pillows, or a combination thereof.
FIG. 22 depicts the frames 52a & 52b in the fully retracted
position which brings the pillows 34 & 36, together in abutting
relationship at the ends of their arms.
[0109] FIG. 23 depicts a front view of the support 32 with the two
pillows 34 & 36 and the joint leaves 50a & 50b adjusted to
a straight angle of 180 degrees and extended. Actuation of the
knobs 56a & 56b and/or buttons 54a & 54b may be required to
adjust the respective frames 52a & 52b and hinges 46 & 48
as previously described in reference to knobs 5a and 5b and buttons
6a and 6b. The first pillow 34 has a first arm 40 and a second arm
42 forming a first opening 44 with space for receiving a
traveller's face, head and neck as depicted in the modes of FIGS.
10, 11 and 14. In some aspects, the first pillow 34 has a recess 38
designed to hold the second pillow 36 with the support 32 is in the
closed position. The second pillow 36 has a third arm 58 and a
fourth arm 60 forming a second opening 62 with space for receiving
a traveller's neck as depicted in the modes of FIG. 10 and FIG. 11
and to support the traveller's chest as depicted in the mode of
FIG. 14. In some aspects, the second opening 62 may be U-shaped.
Each joint hinge has a leaf 50a & 50b, each of which has an
extendable frame 52a & 52b which in this view is shown adjacent
an internal surface of the first pillow 34. As seen in FIG. 23, in
some embodiments the leaves 50a and 50b may be extended. In other
embodiments of the support, however, other arrangements of the
hinge leaves and extendable frames may be used, such as having all
leaves and frames located inside the pillows, or all located on
surfaces of the pillows, or a combination of the two. The buttons
54a & 54b are configured to engage with the leaves 50a &
50b to actuate extension or locking of the frames 52a & 52b. In
some examples, the respective frames 52a and 52b may connect to or
may form a rigid internal support as shown in and described in FIG.
18.

[0112] As the present invention may be embodied in several forms
without departing from the spirit of the essential characteristics
of the invention, it should be understood that the above described
embodiments are not to limit the present invention unless otherwise
specified, but rather should be construed broadly within the spirit
and scope of the invention as defined in the appended claims. The
described embodiments are to be considered in all respects as
illustrative only and not restrictive.
[0113] Various modifications and equivalent arrangements are
intended to be included within the spirit and scope of the
invention and appended claims. Therefore, the specific embodiments
are to be understood to be illustrative of the many ways in which
the principles of the present invention may be practiced. In the
following claims, means-plus-function clauses are intended to cover
structures as performing the defined function and not only
structural equivalents, but also equivalent structures.
[0114] "Comprises/comprising" and "includes/including" when used in
this specification is taken to specify the presence of stated
features, integers, steps or components but does not preclude the
presence or addition of one or more other features, integers,
steps, components or groups thereof. Thus, unless the context
clearly requires otherwise, throughout the description and the
claims, the words `comprise`, `comprising`, `includes`, `including`
and the like are to be construed in an inclusive sense as opposed
to an exclusive or exhaustive sense; that is to say, in the sense
of "including, but not limited to".
