FIELD OF THE INVENTION
[0002] The invention relates to a child's buggy for transporting a
baby or toddler. In particular, the invention relates to a child's
buggy suitable for concurrently transporting two children.
BACKGROUND
[0003] Conventionally, babies and toddlers have been transported in
a buggy. Conventional buggies are suitable for transporting only a
single child. If parents have another child when the earlier child
is still at the toddler stage, it is generally necessary to
purchase a new buggy that is suitable for transporting two
children. Some of those two child buggies are "baby train" types
having two full size fixed in-line seats. Others are twin
configurations having two full sized fixed side-by-side seats. Both
types are large vehicles that are not very manoeuvrable.
Additionally, those vehicles have fixed seats. That is, while the
seats could perhaps be removed from their frames, that would be a
time consuming and complex action requiring the use of tools. It is
not intended for the seats to be removed from the frames in normal
use.
[0004] Another issue is that it is generally desirable that a buggy
has a compact collapsed storage configuration, so it can be readily
transported when not in use. Some "baby train" buggies can fold,
but due to their fixed seat configuration they still take up a
large amount of space when folded. That is also an issue with the
existing side-by-side buggies.
[0005] An alternative configuration two seat buggy is sold by Phil
and Teds Most Excellent Buggy Company Limited of Wellington, New
Zealand, as the Sport buggy. The Sport buggy has a fixed primary
front seat and a detachable secondary rear seat. The buggy can also
be folded for storage. However, the buggy cannot be folded for
storage when the secondary rear seat is attached. With that buggy,
extra actions are required to remove the secondary rear seat prior
to folding the buggy. It is then necessary to reattach the
secondary rear seat after unfolding the buggy if a second child is
to be transported in the buggy.
[0006] In this specification where reference has been made to
patent specifications, other external documents, or other sources
of information, this is generally for the purpose of providing a
context for discussing the features of the invention. Unless
specifically stated otherwise, reference to such external documents
or such sources of information is not to be construed as an
admission that such documents or such sources of information, in
any jurisdiction, are prior art or form part of the common general
knowledge in the art.
[0007] It is an object of at least preferred embodiments of the
present invention to provide a buggy for transporting children that
provides a compact collapsed configuration with two seats without
detaching the secondary seat, and/or to at least provide the public
with a useful alternative.
SUMMARY OF THE INVENTION
[0008] The term `comprising` as used in this specification and
claims means `consisting at least in part of`, that is to say when
interpreting statements in this specification and claims which
include that term, the features, prefaced by that term in each
statement, all need to be present but other features can also be
present. The terms "comprise", "comprises", and "comprised" should
be interpreted in the same way.
[0009] In a first aspect, the invention broadly consists in a buggy
for transporting children, comprising: [0010] a frame; [0011] a
plurality of wheels that are rotatably mounted relative to the
frame to support the frame above a ground surface and which enable
the buggy to be moved along the ground surface; [0012] a primary
seat operatively supported by the frame for supporting a first
child; [0013] a readily attachable and detachable secondary seat
for supporting a second child; [0014] wherein the buggy has an in
use configuration for transporting children and a collapsed storage
configuration, and is convertible between the in use configuration
and the storage configuration whether or not the secondary seat is
attached.
[0015] As used herein, "readily attachable and detachable" means
that the seat can be attached and detached without the use of
tools. The attachment could be any suitable form, such as a quick
release mechanism, clips, clamps, or sleeves that receive portions
of the frame for example.
[0016] The primary seat may be permanently attached, detachable, or
readily attachable and detachable.
[0017] The secondary seat is preferably readily attachable to the
frame in a first position at least partly behind and at least
partly below the primary seat. The buggy is preferably convertible
between the in use configuration and the storage configuration
whether or not the secondary seat is attached in the first
position.
[0018] The secondary seat is preferably readily attachable to the
frame in a second position at least partly above and at least
partly in front of the primary seat. The buggy is preferably
convertible between the in use configuration and the storage
configuration whether or not the secondary seat is attached in the
second position.
[0019] The buggy may be configured such that when the secondary
seat is in the first position at least partly behind and at least
partly below the primary seat, and the buggy is moved from the in
use configuration to the collapsed storage configuration, at least
part of the primary seat must move, at least to some extent, to
enable the buggy to collapse. The configuration may be such that
said at least part of the primary seat is manually moved to enable
the buggy to collapse. However, it is preferred that said at least
part of the primary seat moves automatically as a result of the
secondary seat movement.
[0020] The secondary seat may have a secondary seat frame that
pushes against the primary seat during the collapsing, causing the
movement of at least part of the primary seat. The secondary seat
frame may have a curved configuration to provide a smooth surface
that engages the primacy seat during the collapsing. Alternatively,
the secondary seat itself may push against the primary seat.
[0021] At least part of the primary seat may be invertible to
provide clearance for the secondary seat. Alternatively, the
primary seat could be supported by an arrangement that enables the
primary seat to move out of the way as the buggy is collapsed, such
as hinges or pivots for example.
[0022] It is preferred that the secondary seat is smaller than the
primary seat.
[0023] The secondary seat may be pivotally supported by the frame,
either directly or via a secondary seat frame. The buggy may be
configured such that the secondary seat is selectively pivotable
from an in use position to a storage position, without collapsing
the remainder of the buggy. Preferably, following the movement of
the secondary seat to the storage position, the remainder of the
buggy can then be collapsed around the secondary seat.
[0024] The primary seat may be convertible from a sitting
configuration for supporting a toddler to a lying configuration for
supporting a baby. This, and the option of two attachment positions
for the secondary seat, enables the preferred embodiment buggy to
"grow" with a family. For example, the buggy can support a newborn
or baby in the primary seat in its lying configuration. As the
child grows into a toddler, the primary seat can be used in its
sitting configuration to support the toddler. If a family then has
another baby, the baby can be supported in the primary seat in its
lying configuration, and the toddler can be supported in the
secondary seat in the second attached position at least partly
above and at least partly in front of the primary seat. Once both
children reach the toddler stage, the larger child can be supported
in the primary seat in its sitting configuration, and the smaller
child can be supported in the secondary seat in the first attached
position at least partly behind and at least partly below the
primary seat.
[0025] The primary seat may be permanently attached, detachable, or
readily attachable and detachable.
[0026] In a second aspect, the invention broadly consists in a
buggy for transporting children, comprising: [0027] a frame; [0028]
a plurality of wheels that are rotatably mounted relative to the
frame to support the frame above a ground surface and which enable
the buggy to be moved along the ground surface; [0029] a primary
seat operatively supported by the frame for supporting a first
child; [0030] a secondary seat operatively supported by the frame
for supporting a second child and that is positioned at least
partly behind and at least partly below the primary seat; [0031]
wherein the buggy is convertible between an in use configuration
for transporting children and a folded storage configuration,
without removing the secondary seat.
[0032] The secondary seat may be permanently attached, detachable,
or readily attachable and detachable.
[0033] Preferably, the secondary seat is readily attachable to the
frame in a second position at least partly above and at least
partly in front of the primary seat. The buggy is preferably
convertible between the in use configuration and the storage
configuration whether or not the secondary seat is attached in the
second position.
[0034] The buggy may be configured such that when the secondary
seat is positioned at least partly behind and at least partly below
the primary seat, and the buggy is moved from the in use
configuration to the collapsed storage configuration, at least part
of the primary seat must move, at least to some extent, to enable
the buggy to collapse. The configuration may be such that said at
least part of the primary seat is manually moved to enable the
buggy to collapse. However, it is preferred that said at least part
of the primary seat moves automatically as a result of the
secondary seat movement.
[0035] The secondary seat may have a secondary seat frame that
pushes against the primary seat during the collapsing, causing the
movement of at least part of the primary seat. The secondary seat
frame may have a curved configuration to provide a smooth surface
that engages the primary seat during the collapsing. Alternatively,
the secondary seat itself may push against the primary seat.
[0036] At least part of the primary seat may be invertible to
provide clearance for the secondary seat. Alternatively, the
primary seat could be supported by an arrangement that enables the
primary seat to move out of the way as the buggy is collapsed, such
as hinges or pivots for example.
[0037] It is preferred that the secondary seat is smaller than the
primary seat.
[0038] The secondary seat may be pivotally supported by the frame,
either directly or via a secondary seat frame. The buggy may be
configured such that the secondary seat is selectively pivotable
from an in use position to a storage position, without collapsing
the remainder of the buggy. Preferably, following the movement of
the secondary seat to the storage position, the remainder of the
buggy can then be collapsed around the secondary seat.
[0039] The primary seat may be convertible from a sitting
configuration for supporting a toddler to a lying configuration for
supporting a baby.
[0040] Where specific integers are mentioned herein which have
known equivalents in the art to which this invention relates, such
known equivalents are deemed to be incorporated herein as if
individually set forth.
[0041] The invention consists in the foregoing and also envisages
constructions of which the following gives examples only.

DETAILED DESCRIPTION
[0056] Referring to FIGS. 1 to 2b, a preferred embodiment buggy for
transporting a baby or toddler as indicated by reference numeral 1
and is shown in an in use configuration. The buggy has a frame
having a primary seat frame section 3 and a wheel support section
5. The primary seat frame section 3 has a forward lower section 3a
and an intermediate section 3b. The lower section 3a comprises two
spaced apart members that taper toward and interconnect with each
other at their forward ends to form a nose region 3'. The lower
section 3a is articulated relative to the intermediate section 3b
via couplings 4 that will be described in further detail below. The
intermediate section 3b has members that are generally parallel and
extend upwardly and rearwardly from the couplings 4. The upper
rearward section 3c of the primary seat frame section 3 frame forms
a handle to enable a user to push or pull the buggy.
[0057] The handle 3c is articulated relative to the intermediate
section 3b via couplings 6. The couplings 6 enable the handle to be
selectively tilted relative to the intermediate section 3b, to
obtain a comfortable position for the user. The couplings 6 may
have a frictional mechanism that enables the handle to be tilted
and to then maintain a tilted configuration. Rather than having a
single handle, two spaced apart handles could be provided.
[0058] The primary seat frame section 3 operatively supports a
primary seat for supporting a first child. The primary seat will
generally be formed of a flexible material such as a woven or
non-woven fabric, canvas, or polymeric membrane for example. In
most of the figures, the primary and secondary seats are not shown
so the movement of the frame can be readily determined. However,
FIGS. 8-11 show the collapsing of the buggy including the primary
seat 17a and the secondary seat 8. The primary seat is coupled to
the frame members of the forward section 3a and intermediate
section 3b by any suitable means. For example, fasteners such as
screws, clips, or snap domes could be used to attach the primary
seat to the primary seat frame section 3. Alternatively, the seat
could be formed with sleeves that surround and capture the frame
members. As another alternative, part of the seat could be received
in slots in the frame members. Any other suitable means could be
provided.
[0059] The wheel support section 5 of the frame has a pit of
forward struts 5a that are articulated relative to the frame
members of the forward frame section 3a and extend downwardly and
rearwardly therefrom. A pair of rearward struts 5b are articulated
relative to the frame members of the intermediate frame section 3b
and extend downwardly and rearwardly therefrom. The articulation
could be via hinges or pivots for example. The struts 5a, 5b on
each side of the frame converge towards each other distal from the
primary seat frame section 3. On each side of the frame, the struts
are connected to a wheel support arrangement 11. The connection to
the wheel support arrangement enables the struts to articulate
relative to one another. Each wheel support arrangement 11
rotatably supports a rear wheel 9. The pair of rear wheels support
the frame above the ground. A cross bar 7 extends between the two
rear struts 5b toward the lower end thereof.
[0060] A front wheel 9 is rotatably supported from the nose 3' of
the frame via a front strut 13 to support the frame above the
ground. The wheels are preferably provided with pneumatic tyres to
provide some "all terrain" capability for the buggy. In the
preferred form shown, the front strut 13 is rotatable about a
generally vertical axis, so that the front wheel can change
direction relative to the frame to enhance manoeuvrability of the
buggy. The strut is provided with an adjuster 15. The adjuster
provides a tension adjustment of the front strut 13. Movement of
the adjuster alters the amount of force required to rotate the
strut 13 about the generally vertical axis. At one extreme of the
adjuster, there is very little, if any, tension against the
rotation. At the other extreme, rotation of the front strut may be
prevented to provide a fixed front wheel orientation which may be
preferred by some users. Although not shown in any detail, the
front strut will generally have a shaft extending upwardly
therefrom that is received in the sleeve in the nose section of the
frame. The adjuster 15 will be threaded into the sleeve and will
engage against the shaft to control the tension.
[0061] The buggy is provided with a hood support 16 for a hood that
provides some level of cover for a toddler or baby in the primary
seat. The hood support is preferably angularly adjustable as shown,
and may be fully detachable.
[0062] As can be seen most clearly from FIGS. 1 and 2b, the buggy
also has a secondary seat frame 17 for supporting a secondary seat.
The secondary seat enables the buggy to be used to transport a
second child. In the embodiment shown, the secondary seat frame is
readily attachable to and detachable from the frame 3, 5 without
the use of tools. The secondary seat frame 17 has a generally
inverted "U" configuration. The secondary seat will generally be
smaller than the primary seat.
[0063] As can be seen most clearly in FIG. 7, each forward strut 5a
of the wheel support section is provided with an inwardly directed
spigot 19 toward a lower end thereof. A lower end of each side of
the secondary seat frame 17 contains a complementary recess for
receipt of the spigot 19. The spigot 19 may be configured to snap
fit into the respective recess 20. Alternatively, the spigot may be
a relatively loose fit. The spigot may be biased into a projecting
position.
[0064] Reverting to FIG. 2b, each side of the secondary seat frame
17 is provided with a cross bar coupling 21. The cross bar
couplings each comprise a first recess 21a that receives the
secondary seat frame 17. The cross bar coupling 21 additionally has
a transversely oriented recess 21b for receiving the cross bar. The
secondary seat frame 17 is rigidly supported between the forward
struts 5a and the cross bar extending between the rearward struts
5b. The cross bar couplings 21 provide a pivoting connection
between the secondary seat frame 17 and the cross bar/rearward
struts; however, the pivoting is prevented when the spigots 19 are
received in the recesses 20. This mechanism results in the
secondary seat frame being operatively supported by the primary
seat frame, which in turn is supported above a ground surface by
the wheels.
[0065] The secondary seat frame preferably has some resilience and
the transversely oriented recesses 21b may be slidable on the cross
bar, so the sides of the secondary seat frame can be compressed
towards one another by a user. As that occurs, the recesses 20 will
clear the spigots 19, enabling the secondary seat frame to be
pivoted upwardly and forwardly relative to the cross bar and
rearward struts. Alternatively, if the spigots are biased,
providing sufficient upward force to the secondary seat frame 17
will cause the recesses to clear the spigots, so the secondary seat
frame can be pivoted upward and forward.
[0066] As a further alternative, one or more actuators may be
provided in a position that is readily accessible by a user
standing or crouching behind the buggy, to release the spigots from
the recesses. For example, there may be an actuator on the outside
of each strut 5a, configured such that as the actuators are pulled
outwardly, the spigots clear the recesses.
[0067] Any other suitable means could be used for attaching the
secondary seat frame to the buggy.
[0068] The secondary seat can be mounted to the secondary seat
frame 17 by any of the means described above for the primary seat,
or by any other suitable means.
[0069] It is desirable that the buggy is convertible between the in
use configuration shown in FIGS. 1 to 2b and a collapsed or folded
storage configuration shown in FIGS. 5 and 6. The buggy is designed
such that it is convertible between the in use configuration and
the storage configuration whether or not the secondary seat is
attached.
[0070] The steps for collapsing the frame are shown in FIGS. 3 to
5, and including the material of the seats in FIGS. 8 to 11. The
secondary seat frame is caused to disengage from the spigots 19.
Once the spigots 19 are disengaged from the recesses 20, the
secondary seat frame 17 can be pivoted upward and forward about the
cross bar as shown in FIG. 3 until it is in a position generally
parallel with the rearward struts 5b as shown in FIGS. 4 and 9.
[0071] In the embodiment shown, the primary seat is inverted to the
position shown in FIG. 8 before the secondary seat is pivoted
upward and forward to the position shown in FIGS. 4 and 9. It will
be appreciated that in normal use, the primary seat will generally
hang below the primary seat frame section 3a, 3b.
[0072] The couplings 4 can then be released to enable articulation
between frame sections 3a and 3b. The couplings 4 comprise quick
release levers 4a which provide selective locking and releasing of
the coupling. Each coupling 4 comprises a first portion 4b that is
fixed relative to one of the frame sections 3a or 3b, and a second
portion 4c that is fixed relative to the other of the frame
sections 3a or 3b. The two coupling portions 4b, 4c have a locking
means that prevents relative rotation between those portions and
thereby articulation between frame sections 3a and 3b when the
quick release lever 4a is in the position shown in FIG. 2b. For
example, the opposed faces of the coupling portions 4b, 4c may have
one or more complementary projections and recesses. A biasing means
such as a coil spring for example, biases the opposed faces of the
coupling portions 4b, 4c away from one another so that the
projection(s) and recess(es) are not engaged. However, the leverage
from the locked quick release lever 4a; which acts as a cam; will
bring the projection(s) and recess(es) into engagement with each
other to prevent relative rotation between the coupling portions
4b, 4c. When the frame is to be folded, each quick release lever 4a
is moved outwardly, which enables the spring bias to separate the
projection(s) and recess(es). That enables relative rotation to
occur between the portions 4b, 4c and thereby articulation of the
frame section 3a relative to frame section 3b.
[0073] Once the secondary seat frame 17 has been pivoted to the
position shown in FIGS. 4 and 9, the quick release levers 4a are
released. The upper frame section 3b is provided with a pull bar
23. By pulling the pull bar 23 upwardly, the couplings 4 move
upwardly generally in the direction, indicated by arrow U. The
articulated connection of the forward and rearward struts 5a, 5b
relative to the respective primary seat frame sections 3a, 3b, and
the articulation between the struts 5a and 5b, causes the struts
5a, 5b to move towards one another on each side of the buggy. The
handle end of the intermediate frame section 3b and the nose end of
the forward frame section 3a move downwardly relative to the
couplings 4, so that the frame is converted into the storage
configuration shown in FIGS. 5, 6, and 11. In that configuration,
the buggy is fully collapsed such that the upper frame sections 3a,
3b, and forward and rearward struts 5a, 5b are adjacent and
generally parallel to one another. The secondary seat frame 17 is
positioned generally within the members 3a, 3b, 5a, 5b, and the
secondary seat is positioned generally within the primary seat as
shown in FIG. 11. The quick release levers 4a can then be moved
inwardly to the lock the couplings 4, to prevent unwanted expansion
of the frame from the collapsed storage configuration.
[0074] The buggy may be provided with a mechanism that necessitates
a double action to be undertaken to release the frame from the
position shown in FIG. 4. By way of example only, at least one of
the couplings 4 may have an externally mounted latch that engages
another part of the coupling. To collapse the frame, both couplings
must be released, and the latch must also be released.
[0075] To convert the frame from the collapsed storage
configuration back to the in use configuration, the process is
reversed. That is, the quick release handles 4a are moved outwardly
to release the couplings 4 to enable rotation between the coupling
portions 4a, 4b. The primary seat frame section 3 can then be
extended to the position shown in FIG. 4, and the quick release
levers 4a engaged to prevent unwanted movement of the primary seat
frame section. The secondary seat frame 17 can then be pivoted
downward and rearward until it is in the position shown in FIG. 2a,
and then the secondary seat frame is caused to engage with the
spigots 19.
[0076] It will be appreciated that the above actions can occur
whether or not the secondary seat is attached. During movement of
the secondary seat frame, at least part of the primary seat must
move, at least to some extent, to enable the frame to collapse. In
one configuration, said at least part of the primary seat may be
manually moved. However, it is preferred that said at least part of
the primary seat moves automatically as a result of the secondary
seat moving.
[0077] In the embodiments shown, at least part of the primary seat
is invertible to provide clearance for the secondary seat frame 17.
The entire primary seat may be invertible. As the secondary seat
frame is pivoted upward and forward, the frame 17 may push against
the primary seat causing the movement of said at least part of the
primary seat. The upper end of the frame 17a has a somewhat curved
configuration to provide a smooth surface that engages the primary
seat causing it to move.
[0078] Other alternative configurations could be used. For example,
the primary seat may be supported by an arrangement that enables
the primary seat to move out of the way as the buggy is collapsed,
such as hinges, pivots, or the like for example.
[0079] In the embodiment shown, the secondary seat is selectively
pivotable from an in use position to a storage position, without
collapsing the remainder of the frame. The remainder of the frame,
and the primary seat, can then be collapsed or folded around the
secondary seat frame and secondary seat. It will be appreciated,
however, that the quick release levers 4a could be released prior
to or during the movement of the secondary seat frame 17, to enable
the secondary seat and the remainder of the frame to be collapsed
in a more flowing action.
[0080] FIGS. 1 to 6 show the secondary seat frame 17 attached to
the frame in the first position at least partly behind and at least
partly below the primary seat.
[0081] In the preferred form, the secondary seat frame is readily
detachable from the first position shown in FIGS. 1 to 6, and is
readily attachable in a second position shown in FIG. 7 in which
the secondary seat is in a second position at least partly above
and at least partly in front of the primary seat. To detach the
secondary seat from the first position, the secondary seat frame 17
is released from engagement with the spigots. The cross bar
couplings 21 are releasable from engagement with the cross bar 7
and/or the secondary seat frame 17. The secondary seat can then be
attached in the second position. In that configuration, the pull
bar 23 has been removed, and the pull bar couplings 23a are used to
couple the secondary seat frame 17 to the intermediate section 3b
of the primary seat frame 3. The frame can be collapsed in the
manner described above whether or not the secondary seat frame is
in the second position shown in FIG. 7.
[0082] It will be appreciated that the secondary seat frame, and
thereby the secondary seat, can be supported in the second position
by means other than the pull bar couplings.
[0083] The primary seat is preferably convertible from a sitting
configuration for supporting a toddler to a lying configuration for
supporting a baby. That, and the option of two attachment positions
for the secondary seat, enables the preferred form buggy to "grow"
with the family. That is shown schematically in FIG. 12a-12d.
[0084] FIG. 12a shows the buggy in the configuration in which the
primary seat is in a lying configuration for supporting a newborn
or baby. The adjustment of the primary seat from the sitting to
lying configuration can occur by adjusting zips, clips, straps, or
any other suitable means that enables the portion of the primary
seat that forms a back support in the sitting configuration to move
toward horizontal to support the child in a lying configuration.
Intermediate positions between fully sitting and fully lying may be
provided.
[0085] As the child grows into a toddler, the primary seat can be
used in the sitting configuration to support the back of the
toddler in a more upright position. This is shown in FIG. 12b.
[0086] If a family then has another baby, the baby can be supported
in the primary seat in its lying configuration as shown in FIG.
12c, with the toddler supported in the secondary seat in the second
attached position at least partly above and at least partly in
front of the primary seat. It can be seen that the secondary seat
is at least partly in front of the section of the primary seat 8
that will support the lying baby. When both children reach the
toddler stage, the larger child can be supported in the primary
seat in its sitting configuration, and the smaller child can be
supported in the secondary seat in the first attached position at
least partly behind and at least partly below the primary seat, as
shown in FIG. 12d.
[0087] The above describes preferred embodiments of the present
invention, and modifications can be made thereto without departing
from the scope of the invention.
[0088] For example, while the secondary seat is described as being
readily attachable to and detachable from the frame, that is not
essential. Alternatively, the buggy could be provided in the dual
in-line configuration having a fixed primary seat for supporting
the first child, and a fixed secondary seat for supporting the
second child and that is positioned at least partly behind and at
least partly below the primary seat. The secondary seat will be
attached in a manner such as that described above that allows the
buggy to be collapsed. The secondary seat will generally be smaller
than the primary seat.
[0089] Additionally, the buggy is described as a three wheel buggy.
Rather than having a single front wheel, dual front wheels could be
provided in some configurations.
[0090] Various couplings are shown by way of example only, and
different couplings or attachment means could be used while still
providing the desired functionality. For example, the handle 3c
couplings 6 are described as being frictional mechanism to enable
tilting of the handle 3c to selected positions relative to the
intermediate frame section 3b. Alternatively, the handle could be
fixed relative to the frame, or locking couplings of the type
described for the frame couplings 4 could be used.
[0091] Similarly, rather than using fully locking frame couplings
between the intermediate 3b and forward 3a frame sections, the
frame couplings 4 could use a frictional mechanism.
[0092] Rather than having a seat configuration that has a seat
frame and a fabric, membrane, or the like mounted to the frame, at
least one of the seats may be a more rigid material such as a
polymeric material. If the primary seat is a more rigid material,
the seat will need to pivot or hinge out of the way of the
secondary seat as the secondary seat is moved.
[0093] While the preferred embodiment buggy is shown as an "all
terrain" type of buggy that is suitable for some off road use, it
will be appreciated that the invention can be applied to any
suitable type of pushing vehicle for transporting children.
Therefore, the term "buggy" as used in this specification and
claims should be interpreted to cover other alternative pushing
vehicles, such as strollers, push chairs, and the like.
[0094] The primary seat may be permanently attached, detachable, or
readily attachable and detachable.
[0095] Other possible modifications are listed in the "Summary of
the Invention" section.
[0096] The preferred form buggy can readily transport two children,
yet provides a compact collapsed configuration with two seats
without detaching the secondary seat.
