Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of U.S. Provisional
Application No. 61/515,828, filed Aug. 5, 2011 and is related to
U.S. patent application Ser. No. 12/769,187 filed Apr. 28, 2010
titled CONVERTIBLE CARGO CONTAINER, the entireties of these
contents hereby expressly incorporated by reference herein for all
purposes.
FIELD OF THE INVENTION
[0002] This invention relates generally to an apparatus which is
convertible from a portable cargo container to a wheeled vehicle,
and more particularly, but not exclusively, to a backpack or
article of luggage that includes a deployable wheeled platform so
that the backpack or luggage is convertible to a scooter type
vehicle. Some embodiments of the present invention are particularly
useful for transporting relatively heavy loads along with a human
operator, quickly and with minimal effort.
BACKGROUND OF THE INVENTION
[0003] The subject matter discussed in the background section
should not be assumed to be prior art merely as a result of its
mention in the background section. Similarly, a problem mentioned
in the background section or associated with the subject matter of
the background section should not be assumed to have been
previously recognized in the prior art. The subject matter in the
background section merely represents different approaches, which in
and of themselves may also be inventions.
[0004] Backpacks and articles of luggage combining wheels and
retractable pull handles are well known in the art. Although these
devices aid in transporting cargo, they do not aid in transporting
a human operator.
[0005] Likewise, foldable scooters and bicycles as disclosed in
U.S. Pat. No. 3,680,879 are also well known in the art. These
devices provide a convenient means of transporting a bike or
scooter, but do not provide an operator the ability to carry any
cargo.
[0006] Other portable wheeled devices known in the art are
described in U.S. Pat. No. 6,155,579 which discloses a foldable
child stroller and U.S. Pat. No. 5,791,670 which discloses an
article carrying device. U.S. Pat. Nos. 5,609,278, 5,984,154,
5,483,495, 6,179,176, 4,036,336, 5,749,503, 5,881,932, and
5,743,447 all disclose wheeled carrying devices with alternative
carrying devices.
[0007] Convertible backpacks that also function as rideable
scooters can be susceptible to folding and loading that sometimes
pose physical risks to users. Some physical risks include folding
and scissoring components that, without attention, may lead to
pinching risks as a user transitions between the various modes.
[0008] Further, many deck transition/attachment systems can lead to
unstable connections when the deck is open. It can be the case that
the coupling that enables the end of the deck to fold for storage,
also means that the attachment can be a point of failure during
riding. Failure modes include instability or premature folding,
particularly when a rider pushes forward, or pulls back, on a
steering mechanism.
[0009] In some implementations having a backpack and a folding deck
engaging a back of the backpack, the deck and folding hardware can
add a significant distance between the backpack pack and the
wearer. This distance can degrade the quality of the backpack
function of being worn on the back and carrying items because the
items extend too far away from the user.
[0010] An important consideration for some users is the ease by
which a deck is transitioned between a closed mode and an open
mode. For these users, a simple one-handed operable latching
mechanism is superior. Unfortunately, for any latching solutions
attempting to address other concerns identified herein, it can be a
challenge to also maintain desired simplicity.
[0011] What is needed is a backpack or article of luggage that
includes a deployable wheeled platform so that the backpack or
luggage is convertible to a scooter type vehicle, preferably while
reducing the drawbacks identified herein.
BRIEF SUMMARY OF THE INVENTION
[0012] The following summary of the invention is provided to
facilitate an understanding of some of technical features related
to a backpack including a deployable wheeled riding platform, and
is not intended to be a full description of the present invention.
A full appreciation of the various aspects of the invention can be
gained by taking the entire specification, claims, drawings, and
abstract as a whole. The present invention is applicable to other
types of luggage and other deployable wheeled platforms.
[0013] Overcoming these problems by providing a convertible cargo
container with a deployable wheeled platform is a primary objective
of the present invention. Other objects of the invention will
become apparent in light of the following disclosure and related
claims.
[0014] A combination scooter, pull-pack, backpack with three user
transportation modes: riding, pulling, and carrying. The Product
design incorporates the following combination of unique
characteristics and components: An integrated three-wheeled scooter
where, in ride mode, one wheel is located at the front end of the
cargo carrier, and the other two wheels are located at the rear of
a deployable riding platform so as to be functional in both ride
mode with the platform deployed, and in pull mode with the platform
retracted; an integrated cargo carrier component; a fully
deployable and retractable riding platform with an integrated
linkage between the cargo carrier and platform such that all three
wheels remain in contact with the ground allowing the cargo carrier
to remain standing upright while transforming between open and
closed positions, as well as through the transition between these
positions; an integrated roller(s) mechanism on the end of the
platform that allows the platform to easily roll up and down
between open and closed positions; a latching mechanism(s)
integrated into the platform that allows the platform to be secured
in both open and closed positions; an offset steering mechanism
with a linkage to the front wheel chassis allowing the rider to
turn the scooter's front wheel free of the cargo payload weight
resistance in order to achieve the desired turn; integrated
strap(s) for carrying the entire unit when riding and pulling
aren't convenient; an integrated and vertically adjustable
handlebar component; and an integrated friction brake pedal on the
rear of the platform that slows both rear wheels when depressed in
ride mode.
[0015] Embodiments of the present invention is generally comprised
of three main components, a cargo container 1, a handle 4, and a
retractable platform 7 having wheels 10, which can be converted to
three basic modes, a backpack, wheeled luggage, and a scooter type
vehicle. The first backpack mode is suitable for carrying light
loads or loads over rough terrain. The second wheeled luggage mode
is most suited to carrying cargo in medium traffic areas with
generally flat terrain, such as an airport. The third scooter type
vehicle mode is well suited to transporting a load as well as the
operator great distances over low traffic areas with generally flat
terrain. The third scooter type mode is also particularly
advantageous when time is of the essence. The invention thus
overcomes several problems associated with manually hauling cargo
efficiently, while also providing a means to transport an operator
along with the payload.
[0016] A mobility cargo platform includes a vertically extending
central main support having a longitudinal channel extending from a
bottom end to a top end and a track assembly disposed along an
outside of the vertically extending main support extending upwardly
from a first location proximate the bottom end to a second location
toward the top end; a steering handle rotatably disposed inside the
longitudinal channel and extending from the bottom end above the
top end controlling a direction; a steerage linkage coupled to the
steering handle at the bottom end and extending in a first
direction away from the vertically extending central main support;
a steering wheel assembly, coupled to the steerage linkage; a
stowable rider deck having a proximal end including a track
engagement assembly coupled to the track assembly and a distal end
coupled to a rear wheel assembly, the stowable rider deck
repeatably transitionable between a closed mode in which the
proximal end is proximate the second location with the rider deck
generally vertical and an open mode in which the proximal end is
proximate the first location with the rider deck generally
horizontal; a cargo container coupled to the vertically extending
central main support; and a latching assembly, coupled to the
stowable rider deck, securing the stowable rider deck in the closed
mode.

together with one another in any combination. Inventions
encompassed within this specification may also include embodiments
that are only partially mentioned or alluded to or are not
mentioned or alluded to at all in this brief summary or in the
abstract. Although various embodiments of the invention may have
been motivated by various deficiencies with the prior art, which
may be discussed or alluded to in one or more places in the
specification, the embodiments of the invention do not necessarily
address any of these deficiencies. In other words, different
embodiments of the invention may address different deficiencies
that may be discussed in the specification. Some embodiments may
only partially address some deficiencies or just one deficiency
that may be discussed in the specification, and some embodiments
may not address any of these deficiencies.
[0018] Other features, benefits, and advantages of the present
invention will be apparent upon a review of the present disclosure,
including the specification, drawings, and claims.

DETAILED DESCRIPTION OF THE INVENTION
[0095] Embodiments of the present invention provide a system and
method for a backpack or article of luggage that includes a
deployable wheeled platform so that the backpack or luggage is
convertible to a scooter type vehicle, preferably while reducing
the drawbacks identified herein. The following description is
presented to enable one of ordinary skill in the art to make and
use the invention and is provided in the context of a patent
application and its requirements.
[0096] Various modifications to the preferred embodiment and the
generic principles and features described herein will be readily
apparent to those skilled in the art. Thus, the present invention
is not intended to be limited to the embodiment shown but is to be
accorded the widest scope consistent with the principles and
features described herein.
[0097] Embodiments of the present invention include a cargo
container which can be converted into a scooter type vehicle for
transporting a person and his cargo. Embodiments generally include
three main components, a cargo container 1, a handle 4, and a
retractable platform 7 having wheels 10. The invention has three
use positions including riding, as shown in FIGS. 1-3,
pulling/pushing, as shown in FIGS. 6-7 and carrying as shown in
FIGS. 8-9.
[0098] Referring specifically to FIGS. 1 and 2, the convertible
cargo container is seen in its ride mode having retractable
platform 7 deployed to a position substantially perpendicular to
cargo container 1. The cargo container 1 can be manufactured of
hard shell plastic such as ABS, or lightweight metal. Wheels 10 are
mounted at the outer edges of the lower end of platform 7. Platform
7 can be made of any suitably light, strong material such as
plastic or thin metal to achieve rigidity and low weight. Wheels 10
can be fabricated of any suitable polymer, plastic, rubber, or
synthetic rubber. Additionally, it is noted that the platform could
also have a single rear wheel centrally mounted. Telescoping tube
13 is shown in its extended position and handles 4 are pivoted to
their horizontal position about pivots 19 forming a handle bar 16.
Telescoping tube 13 uses spring biases balls and detents so that it
can maintain its extended and retracted positions. Handles 4 can be
pivoted to a closed position as shown in FIGS. 4-10 when it is
desired to push/pull or carry the cargo container. In push/pull or
carry mode the platform 7 is retracted to a position that is
substantially parallel to the rear side of the cargo container.
Shoulder straps 34 are mounted on the cargo container in a
conventional manner so that the invention can be carried as a
backpack. Shoulder straps 34 may be detachable or retractable. Door
22 can be pivotally mounted or friction fit to provide access to
main storage compartment 25. Platform 7 deploys along a slot 37 in
the cargo container 1 and is slidably connected to telescoping tube
13 at its upper end through a sliding bearing 43.
[0099] Telescoping tube 13 is rotatably mounted in the cargo
container 1 as is distal end, and is connected to steering assembly
28 as shown in FIGS. 11-12. The frame of the steering assembly 28
can be rotated in the cargo container through arcuate slots 29.
Front wheel 31 is rotatably mounted in steering assembly 28. The
telescoping tube and steering assembly can be fabricated from any
suitable lightweight metal or plastic.
[0100] As can best be seen in FIGS. 13-16, a linkage arm 40
pivotally connects platform 7 to the distal end of telescoping tube
13. In this manner, platform 7 can be retracted to its push/pull or
carry position.
[0101] Operation of the device will now be described. When an
operator wants to transport himself and cargo in scooter mode, the
handles 4 are fully deployed as handle bar 16, and the platform 7
is fully deployed at a substantially perpendicular angle to the
cargo container 1. The operator stands on platform 7 and steers the
device with telescoping tube 13 and the attached steering assembly
28. When a high traffic area is encountered, the operator would
step off the platform and pivot the handles to their closed
position as shown in FIG. 4. Platform 7 would then be retracted
along slot 37 until it is substantially parallel to the rear side
of the cargo container 1 as shown in FIGS. 6 and 7. The apparatus
is now in its wheeled luggage mode and can be transport on wheels
10 by pushing or pulling the closed handles. When carrying the
apparatus is desirable, telescoping tube 13 is in its fully
retracted position as shown in FIGS. 8-10, and the apparatus can be
worn as a backpack utilizing shoulder straps 34. The bottom of
platform 7 may be contoured to provide the operator lumber support
when using the apparatus in backpack mode. The transition steps are
reversed when switching from backpack mode to scooter mode. It is
noted that the order the transitional steps are performed is not
crucial, and may be altered.
[0102] The second embodiment of the invention is similar to the
first, having a cargo container 46, a telescoping tube 58, a
platform 52 and wheels 55 as shown in FIGS. 17 and 18. Telescoping
tube 58 is connected to front wheel 64 through the same steering
mechanism described in the first embodiment. As shown in FIGS. 21
and 22 platform 52 is slidably mounted on rods 73. Platform springs
70 bias the platform to its extended position as shown in FIG. 22.
A spring biased platform release hatch 67 retains the platform 52
in its retracted position. Rigid handle 49 has two handle bars 61
which form a central opening. Operation of the second embodiment is
the same as the first except that the platform is deployed to its
extended position by depressing platform release hatch 67, and is
retracted pushing it against the bias of springs 70 until caught by
platform release hatch 67.
[0103] FIG. 23 illustrates a closed isometric view of an alternate
embodiment for a closed convertible backpack, wheeled luggage, and
scooter system, referred to herein for convenience as a mobility
cargo platform 2300. Platform 2300 includes a cargo container 2305,
a retractable, telescoping handle 2310, and a stowable rider deck
2315. The preferred embodiment for platform 2300 includes three
wheels: one steering wheel (not shown) mounted to a steerage
linkage coupled to handle 2310 so that turning handle results in
turning the wheel and controlling direction, and a pair of multiuse
platform rear wheels 2320 coupled to a lower edge of rider deck
2315. As braking assembly 2325, shown in detail below, includes a
pedal actuator 2330 for engaging a pair of brake pads against rear
wheels 2320, and specialized fenders 2335 disposed near rear wheels
2320. A latching system 2340 secures rider deck 2315 in the closed
position. A roller assembly attached to rider deck 2315 and a track
assembly 2345, coupled to handle 2310, guides transition of rider
deck 2315 as it moves between a closed/retracted position and an
open/extended position.
[0104] FIG. 24 illustrates a top plan view of platform 2300 shown
in FIG. 23 with rider deck 2315 opened and extended. A handle lock
is shown for locking handle 2310 in an extended position (shown) or
a retracted position in which handle 2310 is telescoped down (shown
in FIG. 26). FIG. 25 illustrates a front plan view of platform 2300
shown in FIG. 23. In this view, a front steering wheel 2505
(described but not shown in FIG. 23) is coupled to a steering
linkage 2510. Steering linkage 2510 helps to decouple steering
ability from cargo weight.
[0105] FIG. 26 illustrates a back plan view of platform 2300 shown
in FIG. 23 with the rider deck 2315 closed and handle 2310
retracted and stowed. In this configuration, platform 2300 is ready
for storage or to be carried as a bag/backpack using one or more
straps. Handle lock 2405 is used to lock/unlock handle 2310 for
telescoping. FIG. 27 illustrates a bottom plan view of platform
2300 shown in FIG. 23 with rider deck open 2315 and extended.
Steering linkage 2510 is shown coupling handle 2310 to front
steering wheel 2505.
[0106] FIG. 28 illustrates a side view of platform 2300 shown in
FIG. 23 with rider deck 2315 closed, handle 2310 retracted, and
platform 2300 stationary and stable on a surface 2805 as it sits on
all three wheels. FIG. 29 illustrates the side view of platform
2300 shown in FIG. 28 tilted into the pull configuration with
handle 2310 extended, rider deck 2315 closed, and front steering
wheel 2505 lifted up off of surface 2805 as platform 2300 is moved
(e.g., pushed or pulled) over surface 2805. This view highlights
one of the special features of fenders 2335: they are shortened and
extend around but a partial arc of rear wheels 2320 so as to not
interfere with surface 2805 as platform is tilted backwards and
moved.
[0107] FIG. 30 illustrates a side view of platform 2300 shown in
FIG. 23 with cargo container 2305 removed for clarity and with
rider deck 2315 open and handle 2310 extended. FIG. 31 illustrates
the side view of FIG. 30 with cargo container 2305 added for
context.
[0108] FIG. 32 illustrates a side view of platform 2300 shown in
FIG. 23 with rider deck 2315 intermediate its open and closed
positions. A distal end 3205 of rider deck 2315, opposite of a
proximal end 3210 where rear wheels 2320 are attached, glidingly
rolls within track assembly 2345 as it moves up/down to close/open
rider deck 2315 (which retracts/extends rider deck 2315 as well).
To close platform 2300, distal end 3205 is moved up, and as distal
end 3205 moves up in track assembly 2345, rear wheels 2320 move
closer to front steering wheel 2505 and rider deck 2315 moves more
vertical. To open platform 2300, distal end 3205 is moved down, and
as distal end 3205 moves down in track assembly 2345, rear wheels
2320 move further from front steering wheel 2505 and rider deck
2315 moves more horizontal.
[0109] FIG. 33 illustrates a detail view of steering linkage 2510
of platform 2300 shown in FIG. 23. Steering linkage 2510 includes a
lower tube 3305 into which handle 2310 telescopes and within which
handle 2310 rotates. A rotation arm 3310 is coupled to the bottom
of lower tube 3305 and rotates as handle 2310 rotates. A linkage
arm 3315 couples rotation arm 3310 to front steering wheel 2505.
Front wheel is rotatably supported within a caster/bearing 3320
extending from lower tube 3305 by a bracket 3325. Caster/bearing
3320 can provide shock absorption in some embodiments. Steering
linkage 2510 helps improve safety by making turning easier when
weight is added to platform 2300. Without steering linkage 2510, a
user would need to manage the weight with each turn.
[0110] FIG. 34 through FIG. 38 highlight a preferred braking
solution. FIG. 34 illustrates a isometric view of brake assembly
2325 of platform 2300 shown in FIG. 23. Pedal actuator 2330 is
coupled to both rear wheels 2320 to actuate braking with both,
improving safety as compared to a single brake solution. FIG. 35
illustrates a side section view of the brake assembly shown in FIG.
34 and includes brake springs 3505 coupling rider deck 2315 to
pedal actuator 2330 to bias pedal actuator 2330 to the unbraked
position.
[0111] FIG. 36 illustrates a plan view of pedal actuator 2330 of
brake assembly 2325 shown in FIG. 34. Pedal actuator 2330 includes
apertures 3605 to pivotally couple to rider deck 2315 and to
selectively contact a brake pad 3610 to each rear wheel 2320. A
pair of latches 3615 ensure that pedal actuator 2330 does not
rotate too far upward and accidentally trip a rider or otherwise
interfere with availability for braking. FIG. 37 illustrates an
isometric view of brake assembly 2325 shown in FIG. 34 with the
brake pedal shown in FIG. 36 removed. FIG. 38 illustrates operation
of the braking system for platform 2300 shown in FIG. 23. A pair of
brake pads 3800 (in some implementations a single pad) make contact
with both (or a single rear wheel) when pedal actuator 2330 (shown
in FIG. 23) is depressed. A deck support 3805 includes an aluminum
channel fastened to an underside of platform 2300 to provide
structural rigidity. Pedal actuator 2330 hinges about an axle 3810
mounted to deck support 3805.
[0112] FIG. 39 illustrates a roller assembly connecting system 3905
coupling rider deck 2315 to track assembly 2345 for platform 2300
shown in FIG. 23. Roller assembly connecting system 3905 includes
an arm 3910 with a pair of rollers that engage a pair of tracks
inside track assembly 2345. FIG. 40 illustrates a detail view of
roller assembly connecting system 3905 shown in FIG. 39. A roller
4005 of the pair of rollers is shown engaging a track 4010 of track
assembly 2345. The other roller and track are mirror images of
those shown. FIG. 41 illustrates a first side sectional view of
roller assembly connecting system 3905 shown in FIG. 39. FIG. 42
illustrates a second side sectional view of roller assembly
connecting system 3905 shown in FIG. 39. Arm 3910, roller 4005, and
track 4010 are shown.
[0113] In some cases and for some embodiments and applications,
there may be a need or desire to latch rider deck 2315 into the
open position. Some designs can produce undesirable
flexing/pivoting about connection points between rider deck 2315
and track assembly 2345. For example there can be a forward
rotation of handle 2310 while rider deck 2315 is open/extended and
a rider is aboard. FIG. 43 illustrates a plan view for a
representative deck latching system 4305 for platform 2300 shown in
FIG. 23. Deck latching system 4305 of the preferred embodiment is
designed and configured to both latch rider deck 2315 open, but
also to reduce/eliminate forward rotation of handle 2310 when
platform 2300 is ridden in scooter mode. Deck latching system 4305
is a sliding bolt latch design that includes a biased pin for
engagement with, and disengagement from, track assembly 2345.
[0114] FIG. 44 illustrates a plan view for an alternative
representative deck latching system 4405 for platform 2300 shown in
FIG. 23. FIG. 45 illustrates a detail plan view of deck latching
system 4405 shown in FIG. 44. Deck latching system 4405 includes a
pivoting handgrip 4505 that pulls up to initiate disengagement of
deck latching system 4405 from track assembly 2345 and rotates
downward to initiate engagement of track assembly 2345.
[0115] FIG. 46 illustrates a plan view for an alternative
representative deck latching system 4605 for platform 2300 shown in
FIG. 23. FIG. 47 illustrates a detail plan view of deck latching
system 4605 shown in FIG. 46. Deck latching system 4605 includes a
sliding latch 4705 that slides backward to initiate disengagement
of deck latching system 4605 from track assembly 2345 and slides
forward to initiate engagement of track assembly 2345.
[0116] FIG. 48 illustrates a plan view for an alternative
representative deck latching system 4805 for platform 2300 shown in
FIG. 23. FIG. 49 illustrates a detail plan view of deck latching
system 4805 shown in FIG. 48. Deck latching system 4805 includes a
rotating latch 4905 that rotates in one direction to initiate
disengagement of deck latching system 4805 from track assembly 2345
and rotates in the other direction to initiate engagement of track
assembly 2345.
[0117] FIG. 50 illustrates a deck stop 5000 for platform 2300 shown
in FIG. 23. Deck stop 5000 is part of the connection system between
the rider deck and the track assembly shown and described herein.
Arm 3910 is part of deck stop 5000 and includes an aperture 5005
for mounting the rollers that move within the tracks of the track
assembly. A recess 5010 receives and secures a strut underlying the
rider deck to add strength. Latching mechanisms described herein
are responsive to this arrangement of deck stop 5000. Alternatives
to deck stop 5000 may be implemented, for example, deck stop 5000
may be mounted under the rider deck which allows removal of a front
"hump" shown at the front of the rider deck in some figures and
would permit alternate latching mechanisms to be used.
Additionally, for some designs, the hump may on the distal end of
the rider deck can make wearing platform 2300 in backpack mode
uncomfortable for some users. Alternative structures resulting in
reduction/elimination of the hump or this effect are
advantageous.
[0118] FIG. 51 illustrates a deck pull handle 5105 for platform
2300 shown in FIG. 23. FIG. 52 illustrates an isometric view of an
optional backpack pad 5205 used with platform 2300 shown in FIG.
23. Deck pull handle 5105 is, in some embodiments, integrated into
platform 2300, allowing for its deployment and stowage. Backpack
pad 5205 hinges at the top and secures at the bottom with selective
attachment structures (e.g., magnets and the like) in the
folded/closed position.
[0119] FIG. 53 illustrates an alternate deck roller assembly 5300
that is an alternative to roller assembly connecting system 3905
shown in FIG. 39. Deck roller assembly 5300 includes a "spine"
support 5305 (e.g., a tube for handle 2310 or the like) that
includes a pair of integrated flanges 5310. A roller assembly
engages flanges 5310 and includes a roller 5320. Attachment of
rider deck 2315 to assembly 5315 allows opening/closing similar to
that as described herein for other roller assembly
alternatives.
[0120] Other improvements include structures making platform 2300
less bulky, and lighter, and reducing costs of goods. The figures
herein represent prototypes and initial visualizations of the
product and in some ways are sturdier than required for
manufacturing. Some of the designs reflect prototypes built from
1''-thick solid aluminum stock, which is unnecessary for
manufactured products, but appropriate for wanting to withstand
extended testing and potential failure analysis. Alternatives
suitable for manufacture may include designs inspired from folding
ironing tables (which employ very inexpensive yet reliable
fold-and-slide mechanism) and drawer rail hardware. The latter are
made out of punched and formed steel and are rated to support
considerable load. Also, they roll on inexpensive nylon rollers
which could help the platform deploy smoothly. These two points of
departure or inspiration alone would help reduce complexity, bulk,
weight and expense considerably.
[0121] Specifics of shoulder/carrying straps have not been shown as
they may implemented in many different ways. A preferred
implementation includes straps mounted to a side of cargo container
2305 supporting rider deck 2315. A pair of straps are provided on
lateral sides of rider deck 2315, connected at a top and at a
bottom of cargo container 2305. For straps disposed on that side of
cargo container 2305, it is advantageous to provide for a strap
management system to inhibit having straps interfere with use
during ride and pull modes. Strap management may be fairly basic,
including a retaining system for the straps and cargo container
such as hook-and-loop mating patches that removeably attach the
straps to the cargo container and reduce interference. More exotic
systems of buckles and retainers may be used to more securely and
aesthetically retain the straps when not needed or desired, such as
for carrying platform 2300.
[0122] FIG. 54-FIG. 73 illustrate alternative embodiments for a
backpack framework 5400 with a deployable wheeled rider deck (or
platform) 5405. FIG. 54 illustrates a rear perspective view of the
alternative embodiment in an open mode. FIG. 55 illustrates a rear
perspective view of the alternative embodiment in an intermediate
mode. FIG. 56 illustrates a rear perspective view of the
alternative embodiment in a closed mode. Backpack framework 5400 is
configured for use with a removable backpack (not shown) supported
by a backpack support/steering shroud 5410. Backpack framework 5400
is shown without the backpack to better visualize the components
and their operation. It is preferred that a user be able to detach
the backpack from backpack framework 5400 and use the backpack in
standalone fashion, while preserving an option for its use. In
other implementations, the backpack is not required to be
removable, such as having backpack framework 5400 integrated into
the backpack, luggage, container, or the like.
[0123] As described herein, platform 5405 is moveably engaged with
a main tube 5415 that extends generally vertically from
support/shroud 5410 (some embodiments may provide a strictly
vertical arrangement while other arrangements may configure main
tube with a slope). Platform 5405 includes a coupling that enables
a proximal end 5420 (via a lateral linkage) to travel along a track
assembly (in this embodiment one or more (preferably a pair of
opposing) lateral rails), herein referred to as lateral rails 5425
when transitioning platform 5405 between the open mode and the
closed mode. A latching mechanism 5430 locks platform 5405 into the
open mode. Latching mechanism 5430 operates by use of a simple
latch handle 5435 to unlock platform 5405. This enables
single-handed manipulation and operation to transition platform
5405 between the modes. The coupling may include one or more
sliders, rollers and the like. Additionally, the track assembly may
include a wide-range of different rails, channels, guides, and the
like, in addition to or in lieu of the particular implementation
shown and described herein.
[0124] Platform 5405 includes one or more (preferably a pair) of
wheels 5440 at a distal end 5445. One or more (preferably one)
steering wheel 5450 is coupled to main tube 5415 by a steerage
linkage to enable safe steering by virtue of a steering handlebar
5455 rotatably coupled to the steerage linkage through main tube
5415. A preferred implementation includes provision of the three
wheels as described which enables a user to maintain all three
wheels in contact with the ground in either the open mode or the
closed mode.
[0125] Representative attachment points, for example a plate 5460,
are shown to support repeatable (de)attachment of a backpack to
backpack framework 5400. (Other attachment points may be disposed
on other parts, for example, along a perimeter of support/shroud
5410.)
[0126] In FIG. 55, backpack framework 5400 is transitioning from
the open mode (e.g., FIG. 54) to the closed mode (e.g., FIG. 56).
Proximal end 5420 slides up and down along lateral rails 5425 to
fold/unfold platform 5405. In FIG. 56, platform 5405 is completely
folded against main tube 5415.
[0127] FIG. 57 illustrates a side view of the alternative
embodiment in the open mode. FIG. 58 illustrates a side view of the
alternative embodiment in the intermediate mode. FIG. 59
illustrates a side view of the alternative embodiment in the closed
mode. FIG. 58 presents a linkage 5805 that, similarly to linkage 40
in FIG. 14, couples platform 5405 to main tube 5415. The attachment
may be with one or more rollers or sliders or the like. While
linkage 5805 provides advantages in operational stability and
safety, linkage 5805 is a potential source of a pinch hazard,
depending upon an interrelationship and interaction of linkage 5805
with other components. Some embodiments may include an option to
releasably couple linkage 5805 to one or more of platform 5405 and
main tube 5415. This allows linkage 5805 to release and separate
rather than catch and injure any finger or other appendage. Other
protection systems include use of a protective shroud.
[0128] Support/shroud 5410 serves a dual purpose in supporting a
backpack as mentioned, and surrounding and inhibiting access to the
steerage linkage. The steering linkage could be an additional
pinching hazard. There are other potential hazards that may be
shielded with a shroud. For example, a roller/linkage slider 5810
that engages lateral rail(s) 5425 and rolls/slides may in some
implementations be considered to produce a pinch hazard. Use of a
shroud 5815 can reduce such pinch hazards and improves the safety
of such devices.
[0129] Also as seen in FIG. 58, use of roller/slider(s) 5810 and
lateral rail(s) 5425 moves platform 5405 and its connection to main
tube 5415 forward from rear connection and allows for use of simple
latching mechanism 5430 and one-handed transition.
[0130] FIG. 60 illustrates a top view of a portion of the wheeled
rideable platform 5405 engaging main tube 5415. FIG. 61 illustrates
a top view of a pair of lateral rails 5425 used in FIG. 60. A
portion of a steerage linkage 6005 is shown in FIG. 60. Steerage
linkage 6005 is coupled to the front wheel and is operated by
handlebar 5455 through main tube 5415.
[0131] FIG. 62 illustrates a close-up section of a front
perspective view of the alternative embodiment. The close-up is of
backpack framework 5400 in the open mode and latching mechanism
5430 engaged and securing platform 5405 open. FIG. 63 illustrates a
bottom perspective view of the section illustrated in FIG. 62.
[0132] FIG. 64 illustrates the bottom perspective view of the
section illustrated in FIG. 63 without support/shroud 5410.
Steerage linkage 6005 is shown coupling handlebar 5455 to front
steering wheel 5450. Turning handlebar 5455 turns front wheel 5440
by virtue of linkage 6005. This arrangement enables safe turning
and makes it so that turning is independent of the weight and
arrangement of the cargo. Without linkage 6005, a user would need
to "lift" the weight of the cargo for every course correction,
increasing risk as the load increases.
[0133] FIG. 65 illustrates a front perspective view of backpack
framework 5400 in an intermediate (non-open/non-closed mode).
Backpack framework 5400 is shown without support/shroud 5410 and
includes roller/slider linkage 5810 engaging lateral rail 5425. As
seen in FIG. 65, linkage 5805 is implemented as a pair of
mechanical linkages that couple platform 5405 to main tube 5415.
FIG. 66 illustrates a detail view of FIG. 65 including
roller/slider linkage 5810 coupled to lateral rails 5425.
[0134] FIG. 67 illustrates a front detail perspective view of
backpack framework 5400 in the open mode. Roller/slider linkage
5810 is coupled lateral rail 5425.
[0135] FIG. 68 illustrates the perspective view of FIG. 65 with
linkage shroud 5815 removed.
[0136] FIG. 69-FIG. 73 illustrate details of latching mechanism
5430 in latched and unlatched positions. FIG. 69 illustrates a
perspective view of the latch mechanism in the latched position.
FIG. 70 illustrates a side view of the latch mechanism of FIG. 69.
FIG. 71 illustrates a perspective view of the latch mechanism in
the unlatched position. FIG. 72 illustrates a side view of the
latch mechanism of FIG. 71. Latching mechanism includes a housing
6905 that allows proper arrangement, orientation, and operation of
the component parts. These parts include a latch 7005, a latch
handle lever 7010, a compression spring 7015, and latch handle
5435. Compression spring 7015 biases latch 7005 in the locked
position and latch handle 5435 downward. Lifting latch handle 5435
overcomes the biasing and moves latch 7005 to the unlocked
position. Latch 7005 includes a beveled end to enable transition of
the platform from the closed mode to the open mode to automatically
lock without lifting latch handle 5435. On the main tube there is a
complementary latch engagement structure that latch 7005 engages in
the locked position. The beveling allows automatic locking as latch
7005 contacts the latch engagement structure but ensures positive
latching so that locking mechanism 5430 may only be unlocked by
manually and intentionally lifting latch handle 5435.
[0137] During operation, unlocking latching mechanism 5430 by
lifting latch handle 5435 simultaneous unlocks the platform and
provides the user with a handle to continue the motion and in a
single action lift and close the platform. Lifting latch handle
5435 causes latch handle lever 7010 to withdraw latch 7005 and move
it against compression spring 7015, thereby disengaging the lock
mode.
[0138] FIG. 73 illustrates backpack framework 5400 in the open mode
including a side cross-section of engagement of latch mechanism in
the latched position. Shown in FIG. 73 is a complementary latch
engagement structure 7305 that interacts with latch 7005 to lock
and unlock latching mechanism 5430, and platform 5405.
[0139] Optionally, the cargo container of any embodiment can be
made of a suitably durable synthetic or natural fabric shell or it
can be formed of a synthetic or natural fabric shell mounted over a
rigid frame. Additionally, either embodiment can have a power
source such as an electric or gas motor mounted in the platform or
cargo container.
