TRANSPORT PACK WITH EXPANDABLE LOWER PORTION
TECHNICAL FIELD
[0002] The following generally relates to a transport pack with an
expandable lower portion.
DESCRIPTION OF THE RELATED ART
[0003] Food delivery is becoming a more common service. Messengers or
delivery people
will often walk or cycle to deliver food. In order to keep the food warm, or
cool, thermally
insulated covers or bags are provided to keep the food at a desired
temperature.
[0004] For a pizza box, a thermally insulated bag shaped like a square is
used to cover the
pizza box, and a delivery person typically carries the bag by hand. Other
thermally insulated
bags may have carrying handles. Some insulated bags are backpacks. A backpack
is
convenient for a delivery person to carry the food on their back. For example,
a delivery person
rides a bicycle or a motorcycle and, at the same time, wears an insulated
backpack that holds
the food.

DETAILED DESCRIPTION
[0019] It will be appreciated that for simplicity and clarity of
illustration, where considered
appropriate, reference numerals may be repeated among the figures to indicate
corresponding
or analogous elements. In addition, numerous specific details are set forth in
order to provide a
thorough understanding of the example embodiments described herein. However,
it will be
understood by those of ordinary skill in the art that the example embodiments
described herein
=
may be practiced without these specific details. In other instances, well-
known methods,
procedures and components have not been described in detail so as not to
obscure the
example embodiments described herein. Also, the description is not to be
considered as limiting
the scope of the example embodiments described herein.
[0020] A transport pack is also called a backpack, a sack, a
messenger bag, a satchel, and
luggage. A transport pack can be worn by a person, or attachable to a
transporter (e.g. a
bicycle, a motorcycle, a vehicle, etc.), or both. A transport pack can be used
to transport a
number of items. A non-limiting example of items include food items, drink
items, parcels,
letters, etc.
[0021] The appeal of bike courier/bike food delivery is becoming
more popular. It is
recognized that typical transport packs are not suitably shaped to hold and
transport various
types of food shapes. For example, many foods are packaged in flat trays or
boxes, such as
pizza, cake, a tray of cupcakes, pies, casseroles, and food platters. Many
transport bags are
sized for holding smaller food boxes and containers, and are sized to be put
in a typical
backpack. Some people may tilt the flat trays of flat boxes in order to fit
the same into a
backpack, but then the food arrangement in the tray of the boxes will be
ruined. Typical
backpacks are therefore too small to fit larger horizontal food packages.
[0022] Some transport packs are specially shaped and sized to
hold and to thermally
insulate a pizza box, and these transport packs are shaped to be flat. It is
herein recognized,
=
however, that these transport packs are cumbersome and difficult for a person
to carry, such as
on their back. It is also herein recognized that these transport packs, while
suitable for holding
pizza boxes, are not suited for holding other food containers that are taller
(e.g. taller food
boxes, bottles, cylindrical soup containers, etc.).
-3-
23030821.2
CA 02949288 2016-11-22
[0023] . It is herein recognized that it is desirable and helpful
for delivery people or
messengers to be equipped with a transport pack that is reliable and adaptable
for carrying
different shapes of containers, including flat-shaped containers. It is also
desirable and helpful
that the transport pack be easy to transport, such as in a backpack form for a
person to wear, or
some other form that can be carried by a transporter (e.g. attachable to a
bike).
[0024] The proposed transport sack has an upper portion and a
lower portion, and the lower
portion has a telescoping pocket. This telescoping pocket is expandable to
allow a person, or a
transporter, to carry food needs to be held horizontally. The transport sack,
in a preferred
example embodiment is a backpack that can be worn by a person. This allows the
person to
wear the backpack to carry things like pizza, cakes, on their back or bike for
food delivery.
[0025] The transport sack, in another example embodiment, either
in addition or in the
alternative to a backpack style, is attachable to a transporter like a moped,
bicycle, motorcycle,
cart, or other type of vehicle.
[0026] The telescoping function of the pocket in the lower
portion allows a person to pack
the pocket away if they are not using it. In other words, the pocket can be
expanded or
retracted to accommodate different food shapes.
[0027] While many of the examples described herein relate to
transporting food items, it will
be appreciated that the transport sack described herein can also be used to
transport other
types of items that are arranged to be transported horizontally. For example,
architectural
scaled models, a tray of flowers, glassware, or other items may be transported
horizontally
using the transport sack.
[0028] In an example aspect, the bottom of the transport sack has
a removable hardened
base for extra support of the foods that are placed in the transport sack.
[0029] In another example aspect, the transport sack includes a
horizontal divider within its
space to separate the lower portion from an upper portion of the transport
sack. In this way,
additional foods can be put in the transport sack in a stacked manner. The
divider is also useful
to stack foods in the upper portion of the transport sack when the telescoping
pocket is being
= used to hold flatter and wider food items in the lower portion. In a
further example aspect, the
-4-
23030821.2
CA 02949288 2016-11-22
divider is removable and can be fastened to the transport sack with a one or
more of Velcro,
buttons and clasps.
[0030] In another example aspect, the front of the transport sack can be
fully opened to
add/remove items or to configure the divider.
[0031] In another example aspect, the telescoping pocket can be accessed by
unzipping the
pocket from a folded shape to an open shape, and then unzipping the front of
the pocket to
access the cavity.
[0032] In another example aspect, one or more interior surfaces of the
transport sack
include elastic or flexible holders to secure containers within the transport
sack. For example,
the holders are elastic straps and are used to keep liquid containers in a
certain orientation
during transport.
[0033] In another example aspect, the transport sack is made from one or
more shell
materials. For example, the inner shell material is different from the outer
shell material. In
another example, the inner and outer shell materials are the same. In another
example, one of
the inner shell material and the outer shell material is soft, and the other
one of the inner shell
material and the outer shell material is hard or rigid. In another example
embodiment, the inner
and the outer shell materials are soft. Non-limiting examples of inner or
outer shell materials, or
both, include thermoplastic polyurethane (TPU), aluminum foil or aluminum
sheeting (such as
under the tradename Alufoil), polyethylene vinyl acetate (PEVA), fibreglass
shell, etc. One or
more of these materials may be used, and they may be used in various
combinations with each
other.
[0034] In another example aspect, the transport sack body includes a
thermally insulating
material.
[0035] In another example aspect, the transport sack includes one or more
removable
inserts that can be added to the telescoping pocket for added structure. For
example, a sleeve
can be added to the bag allowing a rigid board to be inserted into the
telescope when it is
extended. In an example embodiment, the rigid board that extends is made of
plastic material.
-5-
230308212
CA 02949288 2016-11-22
[0036] In another example aspect, the telescoping pocket has an extended
state and a
retracted state. In another example aspect, the telescoping pocket has one or
more
intermediary states between the extended state and the retracted state. In a
further example
aspect, these intermediary states are at predefined positions.
[0037] In another example aspect, the extended telescoping pocket is
accessed from a front
facing flap located on the lower portion of the transport bag. In another
example aspect, either
in addition or in the alternative, the telescoping pocket is accessible by a
flap (or flaps)
positioned on any one or more of the sides, the bottom, or through the top of
the telescoping
pocket when it is in an extended state.
[0038] In another example aspect, the transport sack has a lower portion
with multiple
telescoping pockets. For example, the telescoping pockets include any two or
more of: a
telescoping pocket extendable from a left side of the transport sack; a
telescoping pocket
extendable from a right side of the transport sack; a telescoping pocket
extendable from a front
side of the transport sack; and a telescoping pocket extendable from a bottom
side of the
transport sack.
[0039] In another example aspect, the transport sack includes straps, hooks
or other
attachment mechanisms to allow strapping the transport sack to a bike, moped,
or motorcycle.
[0040] It will be appreciated that the telescoping feature of the lower
portion of the transport
sack allows foods which are to be delivered horizontally and to be placed on
the back of a bike
rider. The transport sack allows the user versatility and the convenience of
delivering a large
variety of food items, without being overly large or uncomfortable.
[0041] Turning to FIG. 1, an example of a transport sack 100 is shown with
a telescoping
pocket 108a in a retracted position. The telescoping pocket 108a is positioned
on the lower
portion of the transport sack.
[0042] The transport sack 100 has a main body 102 which has a back side, a
front side, a
left side, a right side, a top side, and a bottom side. Positioned on the back
side of the main
body are shoulder straps 110 for a person to wear on their shoulders. The top
side includes a
top flap 101 that can be opened and closed by using a first zipper 105. The
front side includes
a front compartment flap 103 that extends from the bottom of the transport
sack almost to the
=
-6-
23030821.2
CA 02949288 2016-11-22
top side of the transport sack. The front compartment flap 103 can be opened
and closed by a
second zipper 106.
[0043] A front surface 104 of the telescoping pocket is shown in the
retracted state in FIG.
1. A fourth zipper 107, when closed, holds the telescoping pocket in the
retracted state. When
the fourth zipper 107 is opened, the telescoping pocket is extendable to the
extended state.
While the fourth zipper is closed, a third zipper is unseen. The third zipper,
as will be shown
later, is used to open and close the front surface flap 104 of the telescoping
pocket.
[0044] In an example aspect, the bottom side 109 of the transport sack is
flat. In another
example aspect, an exterior pocket 111 is located on at least one of the left
side and the right
side. In another example embodiment, the transport sack includes reflective
material to improve
visibility and, thus, safety, of the transport sack in dark environments (e.g.
at night time).
[0045] FIG. 2 shows the transport sack 100 with the telescoping pocket 108b
in an
extended state. As can better seen in FIG. 2, the telescoping pocket is
positioned on and within
front compartment flap 103 at its lower portion. In the extended position, the
fourth zipper 107 is
opened, so that one half of the fourth zipper 107a is positioned at the
perimeter of the front
surface 104 of the telescoping pocket, and the other half of the fourth zipper
107b is positioned
on the front compartment flap 103.
[0046] In the extended position, a surface 202 protrudes outwards from the
front
compartment flap 103. As better seen in FIGs. 3 and 4, the inner space defined
by the
extended lower portion of the transport sack is therefore enlarged. For
example, this enlarged
inner space at the lower portion can hold tray-shaped objects in a horizontal
position. In other
words, the inner space of the transport sack defined by the main body 102 and
the inner space
defined by the surface 202 of the extended telescoping pocket 108b, also
called a pocket
interior space, together form a joined large interior space.
[0047] The surface 202 is made of a flexible material, so that the surface
202 can be
compressed when the telescoping pocket is in a retracted state and then
extended when the
telescoping pocket is an extended state. The surface 202 is formed from a
fabric, for example.
The surface 202 may be lined with a thermal insulator material that is also
flexible.
-7-
23030821.2
CA 02949288 2016-11-22
[0048] As seen in FIG. 2, the third zipper 201 is positioned between the
two halves of the
fourth zipper 107a and 107b, and is positioned significantly closer to the
front surface 104. The
third zipper 201 is used to open and close the front surface 104, which forms
a flap to access
the enlarged inner space defined in part by the telescoping pocket 108b in the
extended state.
The third zipper 201 is shown in a closed state in FIG. 2, but is shown in an
opened state in
FIGs. 3 and 4.
[0049] Turning to FIGs. 3 and 4, the third zipper is opened. In particular,
one half of the
third zipper 201a forms a perimeter around the front surface 104, and the
other half of the third
zipper 201b forms a perimeter around the edge of the extended surface 202 of
the extended
telescoping pocket 108b. The front surface 104 forms a flap that is laid down
in FIGs. 3 and 4.
[0050] With the front surface 104 in an open position, the inner surface
302 of the front
surface 104 is now visible. Furthermore, the inner surface 301 of the extended
surface 202 is
also shown, whereby the inner surface 301 defines a portion of the extended
interior space in
the lower portion of the transport sack.
[0051] As better seen in FIG. 4, a support surface 400 is positioned inside
and at the bottom
of the transport sack. The inner surface 401 of the back side, and the inner
side surfaces 403
and 402 of the left and the right sides of the transport sack are also visible
when the front
surface 104 is opened and laid down. In an example embodiment, the support
surface is a rigid
board, or a hard board. In an example embodiment, the support surface is made
from a plastic
material.
[0052] It will be appreciated that a depth D1 of the main body 102 plus a
depth D2 of the
surface 202 (i.e. Dl + D2) form a larger depth that represents a dimension of
the extended
telescoping pocket. It will be appreciated that the dimensions of D1 and D2
can be sized to
accommodate different sized trays or boxes that are expected to be carried
when the
telescoping pocket is in the retracted state, and when the telescoping pocket
is in the extended
state.
[0053] Turning to FIG. 5, the telescoping pocket is in the retracted state.
The front
compartment flap 103 is positioned downwards, as the second zipper has been
opened. In
particular, one half of the second zipper 106 is positioned at the perimeter
of the front
-8-
23030821.2
CA 02949288 2016-11-22
compartment flap 103, and the other half of the second zipper 106b is
positioned on the main
body 102. The other half of the second zipper 106b defines a front opening to
the inner space
of the transport pack.
[0054] An inner surface or backside 505 of the front compartment flap 103
is shown in FIG.
5. It also shows the inner surface 302 of the front surface 104 of the
telescoping pocket. As the
fourth zipper 107 is closed, but not seen, and as the third zipper 201 is also
closed, the inner
surface 302 and the inner surface 505 are substantially coplanar.
[0055] In an example embodiment, a removable shelf 501 is positioned
horizontally within
the inner space of the transport pack to divide an upper portion from a lower
portion. In an
example embodiment, the removable shelf 501 is held in place by fasteners 502
positioned on
the interior back and side walls 401, 402 of the transport sack. For example,
the fasteners are
Velcro. In another example, the fasteners are button snaps.
[0056] A front edge of the removable shelf has fixed thereon half a clasp
(e.g. a female
clasp) 503 and the inner surface 505 of front compartment flap 103 has fixed
thereon the other
half of the claps (e.g. a male clasp) 504. The halves of the clasp 503, 504
are connectable
together in order to support the front edge of the removable shelf.
[0057] In an example embodiment, there are two or more clasps located along
the front
edge of the removable shelf. In another example embodiment, Velcro is used to
support the
front edge of the removable shelf.
[0058] In an example embodiment, the removable shelf is made of thermally
insulating
material in order to create a thermal barrier between a lower portion and an
upper portion of the
interior space of the transport sack.
[0059] Turning to FIG. 6, either in addition or in the alternative, the
interior of the transport
pack includes an elastic or flexible sleeve 601 to hold a bottle, or the other
object, in place. In
FIG. 6, the sleeve 601 is oriented horizontally, such that two sides 602 are
fixed to the inner wall
or back surface 401 in order to define opposite openings 603. The sleeve is,
for example, a
type of holder. Other types of holder mechanisms may be fixed to the inner
surfaces of the
transport sack to secure an object in place.
-9-
23030821.2
CA 02949288 2016-11-22
[0060] In another example embodiment, turning to FIG. 7, a holder
701 for larger containers
(e.g. soup containers) is, at one end, fixed to a back inner wall 401 and, at
another end, fixed to
a side inner wall 402. The holder 701 keeps the container in a vertical
orientation. The holder
701 is preferably made of an elastic material. However, other materials may be
used which are
flexible or rigid.
[0061] A second holder 702 is used to hold smaller radius
containers, such as bottles. The
second holder is fixed to a back inner wall 401 and holds a bottle in a
vertical orientation. The
second holder is preferably made of an elastic material to accommodate
different shapes and
sizes. However, other materials may be used, which are flexible or rigid.
[0062] It will be appreciated that the number of holders, the
location of the holders, and the
configuration of the holders within the interior space may vary from the
examples shown in the
figures.
=
[0063] FIG. 8 is an example of a transport sack, with the exterior
body illustrated in faint
lines in order to more clearly show an interior feature positioned at the
bottom of the transport
sack. The features shown in heavy lines are the interior features which are
emphasized in FIG.
8. It will be appreciated that in this "X-RAY" view of FIG. 8 shows these
interior features, which
otherwise would not be clearly visible when inspecting the exterior of the
transport sack. In
particular, the transport sack is shown with the telescoping pocket 108b in an
extended state.
The support surface 400 remains in a fixed position relative to the bottom of
the transport sack.
A telescoping support arm 801 is positioned below, or is embedded within, the
support surface
400. The telescoping support arm 801 is shown in the extended position and
provides support
to a platter, tray or other object that is positioned in the enlarged interior
space of the transport
sack. Although one telescoping support arm is shown in FIG. 8, it another
example
embodiment, there are multiple telescoping support arms. It will also be
appreciated the
thickness and shape of the telescoping support arm may vary from the example
shown in FIG.
8.
[0064] In an example embodiment, the telescoping support arm 801
has a front edge 802
that is fixed to a front bottom edge 804 of the telescoping pocket 108b.
Therefore, when the
telescoping pocket 108b is extended, then the telescoping support arm 801 also
extends
outwards. Therefore, in operation, when a user pulls the telescoping pocket to
the extended
-10-
23030821.2
CA 02949288 2016-11-22
state, in turn, the telescoping support arm also extends. Or, conversely, when
the telescoping
support arm 801 extends outwards, then the telescoping pocket 108b is also
extended.
Therefore, in operation, when the telescoping support arm extends outwards,
such as by a
spring force or tension force, then the telescoping pocket is also extended.
[0065] In another example embodiment, the front edge 802 of the telescoping
support arm
and the front bottom edge 804 of the telescoping pocket 108b are detached from
each other.
Therefore, in operation, a user can separately pull forward or retract the
telescoping pocket, and
separately pull forward and retract the telescoping support arm. In an example
embodiment, a
tab 803 or other graspable feature is positioned on the front edge 802 of the
telescoping support
arm, and a user can use this feature to pull out the telescoping support arm.
[0066] A retracted state of the telescoping support arm 801' is shown in
dotted lines. All or
the majority of the telescoping support arm's length is hidden within or under
the support
surface 400 in the retracted state.
[0067] In an example embodiment, the telescoping support arm is made of the
same
material as the support surface 400. In an alternative embodiment, the
telescoping support arm
and the support surface 400 are made of different materials.
[0068] In some example embodiments, the telescoping support arm is not
spring loaded.
[0069] In other example embodiment, the telescoping support arm is spring
loaded. FIG. 9
shows an elastic string or tension cord 901 in an shortened state, and with
the telescoping
support arm 801 in the extended state. The tension cord 901 is attached at its
ends to two
fixture points positioned at the sides or the front of the support surface
400.
[0070] When the telescoping support arm is in a retracted state, as shown
in the position
801', the tension cord is in elongated 901' and is put under increased or
greater tension
compared to the shortened state. Two latches 903 and 904 hold the telescoping
support arm in
a retracted state, and hold the tension cord 901' in the elongated state. When
the latches are
released, the tension cord 901' shortens due it its elasticity, and pulls the
telescoping support
arm forward to the extended state.
-11-
23030821.2
CA 02949288 2016-11-22
[0071] In an example embodiment, one latch mechanism 903 is
positioned adjacent to, or
at, the back edge 905 of the telescoping support arm. The complimentary latch
mechanism 904
is positioned at the bottom surface of the transport sack, and is adjacent to,
or near, the back
edge of the bottom surface of the transport sack. When the latches 904 and 904
are locked
together, a user can release the latch 904 (e.g. by a pressing or pulling
action) to decouple the
latches from each other and, in turn, causing the telescoping support arm to
spring forward to
an extended state.
[00721 In an example feature of FIG. 9, the telescoping support
arm 801 has a front edge
that is fixed to a front bottom edge of the telescoping pocket 108b.
Therefore, the telescoping
pocket springs forward to the extended state when the telescoping support arm
springs forward.
[0073] FIG. 10 shows an alternative example spring mechanism. One
or more compression
springs 1001 are positioned between a back edge of the support surface 400 and
the back edge
of the telescoping support arm. The spring or springs 1001 pushes the
telescoping support arm
=
forward.
[0074] FIG. 11 shows another example embodiment of a mechanism
that is retractable, and
automatically biases the telescoping pocket to an extended state. Positioned
within or below
the support surface 400 is a resilient ring 1101 that, in its uncompressed or
default state,
extends from the back edge of the support surface 400 to a given position
beyond the front
edge of the support surface 400. The distance between (a) the front edge of
the support
surface and (b) the given position beyond the front edge is approximately the
same depth of the
telescoping pocket 108b in the extended state.
[0075] The resilient ring 1101 is also able to be flexed or
compressed so that it extends
from the back edge of the support surface 400 to the front edge of the support
surface 400. In
this compressed state, the sides of the resilient ring bow outwards. In other
words, the width of
the resilient ring is wider in the compressed state, compared to the width of
the resilient ring in
the uncompressed state.
[0076] The resilient ring also acts as an telescoping support
structure for the bottom of the
telescoping pocket 108b in the extended state.
-12-
23030821.2
CA 02949288 2016-11-22
[0077] In an example embodiment, a fixture point 1102 (e.g. a sewn fabric,
string, a claps,
etc.) fixes a front end of the resilient ring to the front bottom edge 804 of
the telescoping pocket
108b. Another fixture point 1103 fixes a back end of the resilient ring to a
back bottom edge of
the transport sack.
[0078] FIG. 12 shows another example embodiment of a transport sack 1200.
It includes
multiple telescoping pockets 1201, 1202 and 1203 each in an extended state.
For example, the
