TECHNICAL FIELD
[0002] The present invention relates generally to the field of
child support devices, and more particularly to child high
chairs.
BACKGROUND
[0003] Conventional children's high chairs typically include a
child seat elevated above a floor by a frame. Certain high chairs,
however, are provided with an additional seat that can be removably
secured to the high chair's child seat in order to convert the high
chair for use by children of different ages. In some previously
known devices, when the booster seat is detached from the high
chair, it is typically coupled to a separate base member and can
then be secured to a standard high chair for use as a booster.
[0004] Accordingly, it can be seen that needs exist for an improved
convertible high chair that is easier and more convenient for users
to convert and that includes a removable booster seat capable of
stably supporting itself on a support surface (e.g. a standard
chair) without the need to be secured to a separate component (e.g.
a separate base member).
[0005] It is to the provision of a children's high chair meeting
these and other needs that the present invention is primarily
directed.
SUMMARY

decoupled from the first child seat.
[0008] In another aspect, the present invention relates to a
convertible high chair including a frame configured to rest on the
floor, a first child seat defining a first seating portion and a
second child seat defining a second seating portion. The first
child seat is coupled to the frame and supported above the floor
and the second child seat is configured to be removably coupled to
the first child seat. The second child seat includes a base with a
downward extending skirt. The skirt is configured to extend
substantially around the entirety of the first seating portion of
the first child seat when the second child seat is coupled to the
first child seat.
[0009] In still another aspect, the present invention relates to a
convertible high chair including a frame configured to rest on the
floor, a first child seat defining a first seating surface, a
second child seat defining a second seating surface and a tray
assembly. The first child seat is coupled to the frame and
supported above the floor and the second child seat is configured
to be removably coupled to the first child seat. The tray assembly
includes a base tray pivotally coupled to the second child seat and
a detachable tray removably coupled to the base tray.
[0010] In still another aspect, the present invention relates to a
tray assembly for a children's high chair including a base tray, a
detachable tray removably coupled to the base tray, and an
auxiliary tray extensible and retractable relative to the
detachable tray.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS
[0067] The present invention may be understood more readily by
reference to the following detailed description of example
embodiments taken in connection with the accompanying drawing
figures, which form a part of this disclosure. It is to be
understood that this invention is not limited to the specific
devices, methods, conditions or parameters described and/or shown
herein, and that the terminology used herein is for the purpose of
describing particular embodiments by way of example only and is not
intended to be limiting of the claimed invention. Any and all
patents and other publications identified in this specification are
incorporated by reference as though fully set forth herein.
[0068] Also, as used in the specification including the appended
claims, the singular forms "a," "an," and "the" include the plural,
and reference to a particular numerical value includes at least
that particular value, unless the context clearly dictates
otherwise. Ranges may be expressed herein as from "about" or
"approximately" one particular value and/or to "about" or
"approximately" another particular value. When such a range is
expressed, another embodiment includes from the one particular
value and/or to the other particular value. Similarly, when values
are expressed as approximations, by use of the antecedent "about,"
it will be understood that the particular value forms another
embodiment.
[0069] Various embodiments of the present invention are directed to
a convertible children's high chair. According to various
embodiments, the convertible high chair generally comprises a first
child seat supported above a floor by a high chair frame, and a
second child seat configured for being removably coupled to the
first child seat. The second child seat is configured such that,
when detached from the high chair's first child seat, it can be
used apart from the high chair as a booster seat (e.g., secured to
the seating surface of a standard chair or another support surface)
in a different mode of use independent of the frame. In certain
embodiments, the convertible high chair is convertible for use by
children of varying ages. For example, when the second child seat
is coupled to the first child seat, the high chair functions in a
first configuration as an infant high chair. In a second
configuration, when the second child seat is detached, the high
chair functions as a toddler booster seat. In a third
configuration, the second child seat can also include a base
surface configured to stably support the second child seat on a
separate support surface (e.g., without the need to be attached to
or mounted to a separate base or support member). In the third
configuration, the second child seat functions on its own as an
infant or toddler booster seat.
[0070] With reference now to the drawing figures, wherein like
reference numbers represent corresponding parts throughout the
several views, FIGS. 1-49 show a convertible high chair 100
according to an example embodiment of the present invention. The
high chair 100 generally includes a frame 200, a first child seat
300 and a second child seat 400 that includes a tray assembly 500.
FIGS. 1-3 illustrate the convertible high chair 100 in a first
configuration or mode of use as an infant high chair, in which the
second child seat 400 is coupled to the first child seat 300 and
thereby supported by the frame 200 in a high chair
configuration.
[0071] FIG. 4 illustrates the second configuration in which the
convertible high chair 100 is adapted for a second mode of use as a
stand-alone toddler booster seat. In this configuration, the second
child seat 400 is decoupled from the first child seat 300 and is
removed from the high chair 100 to expose the seat portion 310 of
the first child seat. The first child seat 300 is supported a
distance above the floor by the frame 200.
[0072] The frame 200, shown in FIGS. 4-6, is generally configured
for resting on a floor or other support surface. The frame 200
generally includes a front U-shaped frame member 210 and a back
U-shaped frame member 220 connected at a hubs 230 positioned on
either side of the frame. The frame members 210, 220 each include a
cross frame member 212, 222 and generally upright frame members or
legs 214, 224 angled in the form of an A-frame support structure.
The cross frame members 212, 222 extend generally parallel with the
support surface or floor. The upright frame members 214, 224 extend
at an upward angle from the cross frame members 212, 222 to the hub
230. In the depicted embodiment, the front upright frame members
214 are attached to the hubs 230 in a fixed position, whereas the
back upright frame members 224 are pivotally attached to the hubs.
This pivotal attachment allows a user to fold the frame 200 from an
expanded in-use position, shown in FIG. 5, to a more compact
storage position, shown in FIG. 6. The hubs 230 can each include a
locking mechanism that locks the frame in the in-use and/or storage
position. In the example embodiment, the locking mechanism locks
the back frame member 220 in both the in-use and folded position.
The hubs 230 each include a button 232 that, when pressed, unlocks
the locking mechanism and allows the back frame member 220 to pivot
between the in-use and folded position. In example embodiments,
two-handed operation by an adult is utilized to fold the mechanism,
to prevent inadvertent release. In alternate embodiments, another
release mechanism, such as a handle or switch, can be used. In
alternate embodiments, the front frame member 210 or both frame
members are able to pivot. In the depicted embodiment, the frame
200 also includes a plurality of wheels 240 (e.g., castors) that
permit the frame 200 to be rolled by a user along the floor. In
example embodiments, the wheels 240 have a diameter of at least
about 1.5 inches to help the frame roll along a thick carpet. The
wheels 240 optionally include caster mechanisms for rotation and
turning. In alternate embodiments, larger or smaller wheel
diameters can be used. In the depicted embodiment, wheel attachment
protrusions 242 attach the wheels 240 to the frame members 210,
220. The protrusions 242 position the wheels 240 a distance
outwardly away from the frame members 210, 220 for improved
stability. In alternate embodiments, the wheels 240 attach directly
to the frame members 210, 220. The wheels 240 can include a lock
and release or braking mechanism 244 for selectively locking the
wheels to prevent rolling or releasing the wheels to allow rolling.
In alternate embodiments, the frame 200 can include other sliding
or rolling means.
[0073] In example embodiments, the frame 2200 of the high chair
2000 can also include additional rolling elements 2246, as shown in
FIGS. 51 and 52. In the depicted embodiment, the back cross frame
member 2222 can include one or more rollers positioned in between
the wheels 2240. The rollers 2246 are configured to not engage the
support surface when the frame 2200 is in the unfolded use
position, as shown in FIG. 51. In example embodiments, the rollers
2246 have a smaller diameter than the wheels 2240. The rollers 2246
are configured to engage the support surface when the frame 2200 is
pulled by a caregiver in the folded position, as shown in FIG. 52.
The rollers 2246 help the caregiver move the high chair 2000 in
this folded, angled position.
[0074] The first child seat 300, shown in FIGS. 7-15, is attached
to the front vertical frame members 214 of the frame 200 and
supported a distance above the support surface. The first child
seat 300 generally includes a seat portion 310, a backrest 320 and
optionally a footrest 330. In the depicted embodiment, the seat
portion 310 includes a seating surface 312 and shoulders or
armrests 314. The seating surface 312 provides a surface
substantially parallel to the floor or support surface configured
to support a child seated thereon. The shoulders 314 extend
upwardly from lateral sides and back of the seating surface 312.
The shoulders 314 can act as armrest for a child seated therein.
The backrest 320 extends upward from the seating surface 312 to
provide back support to a child seated thereon. In the example
embodiment, the back rest 320 is pivotally attached to the seating
surface 312 and is able to be moved between an in-use position,
shown in FIG. 7, and a folded position, discussed further below. In
alternate embodiments, the back rest 320 is detachable from the
first child seat 300 or fixed in position. In the depicted
embodiment, the first child seat 300 is generally dimensioned to
accommodate a toddler-age child. As such, the convertible high
chair 100 is well suited to function as a stand-alone toddler high
chair or booster in the second configuration. However, as will be
appreciated from the description herein, various other embodiments
of the first child seat 300 can be dimensioned for supporting
children of any age.
[0075] In example embodiments of the first child seat 1300, the
shoulders 1314 are dimensioned to comply with applicable safety
standards, as shown in FIG. 50. For example, the European Committee
for Standardization's requirements for Children's High Chairs
includes minimum dimensions for lateral protections. In example
embodiments, the shoulders 1314 are configured such that the
distance between the top of the shoulder and the bottom of the back
rest 1320 is at least about 145 mm. The distance between the top of
the shoulder 1314 and the bottom of the back rest 1320 can also be
at least about 150 mm. In other embodiments, the distance between
the top of the shoulder 1314 and the bottom of the back rest 1320
can be smaller than 145 mm or larger than 150 mm.
[0076] The footrest 330, shown in detail in FIGS. 8-12, includes a
footrest base 332 and a ledge 334. The foot rest base 332 is formed
from a panel that, in the in-use position shown in FIG. 7, extends
downward from the substantially front edge of the bottom of the
seat portion 310 of the first child seat 300. In the in-use
position, the footrest base 332 is positioned substantially
perpendicular to the seating surface 312. The ledge 334 is
removably attached to the footrest base 332 such that the flat
surface of the ledge is substantially perpendicular to the foot
rest base 332. The ledge 334 is configured to, in the in-use
position, provide a surface to support the feet of a child seated
in the first child seat 300. The footrest ledge 334 can be
positioned on the footrest base 332 at a variety of distances
relative to the seating surface 312 to accommodate different leg
lengths of the child seated therein. In the depicted embodiment,
the footrest base 332 includes a plurality of receiving slots 336
and the ledge 334 includes a tab 338 extending perpendicularly from
the ledge surface. To removably attach the ledge 334 to the
footrest base 332, the tab 338 of the ledge is inserted through a
slot 336 in the foot rest base and positioned such that a flat
portion of the tab abuts the back of the footrest base, as shown in
FIG. 11. To adjust the distance of the ledge 334 relative to the
seating surface 312, the ledge is attached to different slots 336
in the footrest base 332. In alternate embodiments, the footrest
ledge 334 can be repositionably attached to the footrest base 332
using other attachment means. In the depicted embodiment, the
footrest 330 is movable between the in-use position, shown in FIG.
7, and a folded position, shown in FIG. 12. The footrest base 332
is pivotally attached to the bottom of the seat portion 310,
allowing the footrest 330 to be folded to a position underneath and
parallel to the bottom of the seat portion, shown in FIG. 12. In
alternate embodiments, the foot rest 330 removable from the first
child seat 300. In other embodiments, the footrest is
repositionably attached to the frame 200.
[0077] The first child seat 300 is repositionably attached to the
front upright frame members 214 of the frame 200 to provide height
adjustment, as shown in FIGS. 13-15. In the depicted embodiment,
the first child seat 300 includes attachment collars 340 positioned
either side of the seat portion 310. The collars 340 are configured
to surround and couple to the front upright frame members 214. This
coupling is configured to be height adjustable in order to allow an
adult caregiver to selectively raise and lower the first child seat
300. The attachment collars 340 each include a spring biased lever
342 with a first end configured to engage a series of notches or
holes 216 on the back side of the front upright frame members 214,
as shown in FIG. 14. The levers 342 are spring biased such that the
first end remains engaged with the holes 216. To adjust the height
of the first child seat 300, the adult caregiver can push the
second end of the levers 342 to disengage the holes and the collars
can be slid along the front vertical frame member 214 to the
desired height. The first end of each lever 342 is released to
reengage the holes 216 corresponding to the desired height. In the
depicted embodiment, the second end of the lever 342 includes a
hook portion configured to assist the caregiver when lifting or
lowering the first child seat 300 to a different height. In
alternate embodiments, alternate height adjustment mechanisms can
be used. In alternate embodiments, the first child seat can be
repositionably attached to the back upright frame members 224. In
example embodiments, two-handed operation prevents inadvertent
release and movement, and positioning the actuators away from
access by a child seated in the seat prevents the child from
accidentally releasing and moving the seat position.
[0078] In other embodiments of the first child seat 3300, the
attachment collars 3340 include a hook-shaped portion 3344
independent of the lever 3342, as shown in FIG. 53. The hook-shaped
portion 3344 is generally positioned above the lever 3342. The
hook-shaped portion 3344 is configured to assist the caregiver when
lifting or lowering the first child seat 3300 to a different
height. In this configuration, the caregiver can use the
hook-shaped portion 3344 to support the weight of the first child
seat 3300 independent of the pushing or releasing of the lever
3342.
[0079] In alternate embodiments of the high chair 5000, the first
child seat 5300 is attached to the front upright frame member 5214
in a fixed position. In this embodiment, shown in FIG. 55, the
front upright frame members 5214 can include a telescoping feature
configured to adjust the height of the first child seat 5300. For
example, the front upright frame members 5214 can include a base
collar 5216 and an upper leg 5218. The upper leg 5218 is configured
to slidingly engage with the base collar 5216. The position of the
upper leg 5218 within the base collar 5216 can be adjusted to
adjust the length of the upright frame member 5214 and thereby the
height of the first child seat 5300. In alternate embodiments, both
the front upright frame member 5214 and the back upright frame
member 5224 include telescoping features.
[0080] The second child seat 400, shown in FIGS. 16-19, generally
includes a base 410 and a seat back 430. The base 410 includes a
seating surface 412 that provides a surface substantially parallel
to the floor and is configured to support a child or infant seated
thereon. In the depicted embodiment, the seating surface 412
includes an upwardly extending crotch restraint 414 configured to
prevent a child from sliding off the seating surface. The base 410
also includes shoulders 420 that extend upwardly from the lateral
sides of the seating surface 412 and can function as armrest for a
child seated therein. The seat back 430 is configured for
supporting the back of child seated on the seating surface 412. In
example embodiments, the seating surface 412, crotch restraint 414,
shoulders 420 and seat back 430 are generally dimensioned to
accommodate and infant-age child. Various other embodiments of the
second child seat 400 can be dimensioned for supporting children of
any age. The seat back 430 can include attached soft goods 432. In
the depicted embodiment, the soft goods 432 are configured to
extend over the seating surface 412. The seat back 430 can also
include a safety harness 434 configured to secure an infant or
child within the second child seat 400. In alternate embodiments,
the second child seat 400 includes handles configured to provide an
easy gripping surface for a user to grasp and move the second child
seat.
[0081] In example embodiments, the angle of recline between the
seat back 430 and the seating surface 412 can be adjusted. As shown
in FIGS. 18 and 19, the shoulder 420 of the seat base 410 includes
a curved surface 422 with a series of positioning notches 424,
corresponding to a series of recline angles, and a receiver 426.
The seat back 430 includes a positioning pin 436 and a pivot
projection 438. The pivot projection 438 is configured to pivotally
couple with the receiver 426 such that the seat back 430 can pivot
relative to the seating surface 412. The positioning pin 436 is
configured to engage with a positioning notch 424 to hold the seat
back 430 at a certain recline angle. To adjust the recline angle of
the seat back 430, the user can lift the seat back to disengage the
positioning pin 436 from a positioning notch 424 and slide the
positioning pin along the curved surface 422 to engage the
positioning notch corresponding to the desired recline angle.
[0082] The second child seat 400 can be attached to the first child
seat 300 in a first configuration of the convertible high chair 100
as shown in FIGS. 1-3, for example for use as a high chair for an
infant. FIG. 20 depicts the third configuration of the convertible
high chair 100 in which the second child seat 400 is adapted as an
infant booster seat. In this configuration, the second child seat
400 is configured for independent use apart from the high chair
frame 200. The second child seat 400 is configured to rest on a
separate support surface, for example, a generally flat seat
surface of an adult dining chair. The bottom of the second child
seat base 410 is configured to rest directly on the support
surface, without the need for a separate base component. In example
embodiments, straps are provided to secure the second child seat
400 to the adult dining chair or other support surface.
[0083] FIGS. 21-28 illustrate the mechanisms used to removably
couple the second child seat 400 to the first child seat 300, and
thereby to the frame 200. In the depicted embodiment, the back rest
320 of the first child seat 300 is moved to the folded position
before the second child seat 400 is attached. As shown in FIGS. 22
and 23, the back rest 320 of the first child seat 300 includes a
spring biased locking handle 322 configured to engage a slot 316 in
the first child seat shoulder 314 which holds the back rest in the
in-use position. To move the back rest 320 to the folded position,
the user can pull the handle 322 to release it from the slot 316
and fold the back rest down such that it is substantially parallel
to and abuts the seating surface 312. In alternate embodiments, the
second child seat 400 can be coupled with first child seat 300 when
the back rest 320 is in the in-use position or the back rest can be
removed from the first child seat. In the depicted embodiment, the
bottom of the base 410 of the second child seat 400 is dimensioned
to fit over the first child seat 300. The base 410 of the second
child seat 400 includes a downwardly extending lip or skirt 416
around its outer periphery, shown in FIG. 24, and the seat portion
310 of the first child seat 300 includes a ledge 318 around its
outer periphery, shown in FIGS. 22 and 23. The lip 416 is
configured to cover the seating surface 312 and shoulder 314 of the
first child seat 300 and rest on ledge 318, as shown in FIG. 30. In
example embodiments, the skirt 416 extends entirely around or
substantially entirely around the outer periphery of the second
child seat base 410. When coupled to the first child seat 300, the
skirt 416 of the second child seat 400 extends around the entirety
of the seat portion 310 of the first child seat 300, covering the
front, back, and both sides of the first child seat. In the
depicted embodiment, the first child seat 300 and second child seat
400 are dimensioned to have a flush outer surface when coupled
together. Having the second child seat base 410 wider than the
first child seat 300 creates stability, both when the second child
seat 400 is in the first configuration or in use as a booster seat
in the third configuration.
[0084] In alternate embodiments of the high chair 5000, the second
child seat 5400 attaches directly to the frame 5200, as opposed to
attaching to the first child seat. As shown in FIG. 55, the frame
can include attachment mechanisms 5250 configured to releasably
engage with cooperating attachment mechanisms 5450 on the second
child seat 5400. This high chair 5000 can also include the
telescoping front upright frame member 5214 discussed above.
[0085] The second child seat 400 includes a locking latch and
release mechanism 450, shown in FIGS. 24-28, configured to hold the
second child seat 400 coupled to the first child seat 300. The
locking mechanism 450 includes a first and second spring biased
ridge 452, 454 coupled by a connecting rod 456 positioned on the
bottom of the second child seat base 410 within the lip 416. The
first ridge 452 in positioned adjacent the front of the base 410
and the second ridge 454 is positioned adjacent the back of the
base. The first ridge 452 is connected to a release handle 458 that
extends through the lip 416 at the front of the base. The first
child seat 300 includes a first slot 352 positioned on the front of
seat portion 310 and a second slot 354 positioned on the portion of
shoulder 314 adjacent the back of the seating surface 312. The
first and second ridge 452, 454 are configured to engage the first
and second slot 352, 354 respectively when the second child seat
400 is coupled to the first child seat 300, thereby locking the
second child seat to the first child seat. To release the second
child seat 400 from the first child seat 300, the user pulls the
release handle 348 which laterally moves and retracts the first and
second ridge 452, 454 from the first and second slot 352, 354 and
enables the second child seat 400 to be removed from the first
child seat 300.
[0086] In other embodiments, the second child seat 4400 includes a
locking latch and release mechanism as discussed above. But in this
embodiment, the seat release handle 4458 extends to the bottom edge
of the skirt 4416 of the second child seat 4400, as shown in FIG.
54. This configuration strengthens the base 4410 of the second
child seat 4400 and makes the base easier to manufacture.
[0087] A multi-tray tray assembly 500 is shown according to example
embodiments in FIGS. 29-47, and generally includes a base tray 510
and a larger detachable tray 530. Optionally, the tray assembly 500
includes an auxiliary tray 540, a tray liner 560 and a plate 570.
The base tray 510, shown in FIGS. 29-33 generally includes two arms
512 and a substantially rectangular work surface 514. The base tray
510 can include a lip around the outer periphery of the upper

for holding food, toys or other items in a location accessible by
the child seated in the high chair 100. The arms 512 of the base
tray 510 are coupled to the shoulder 420 of the second child seat
400. The base tray 510 is positioned such that the seating surface
412 of the second child seat 400 is between the arms 512 of the
base tray 510. One arm 512 is pivotally coupled to the shoulder
420, as shown in FIG. 32, and the other arm is releasably coupled
to the shoulder so that the base tray 510 can be pivoted away from
the second child seat 400, as shown in FIG. 30. This feature helps
the caregiver access the second child seat 400 when seating or
removing the child. The arm 512 with the releasable coupling
includes a plunger 516. The plunger 516 is configured to fit within
a channel 440 in the shoulder 420. The plunger 516 includes a
locking mechanism comprising a spring biased button 518 coupled to
an arm 520. The arm 520 is configured to engage a notch 442 on the
outside of the channel 440 to lock the plunger 516 in engagement
with the channel, as shown in FIG. 33A. The user can depress the
button 518 to move the arm 520 out of engagement with the notch 442
in order to release the plunger 516 from the channel, as shown in
FIGS. 33B and 33C. In example embodiments, the channel includes a
spring 444 biasing the plunger 516 away from the channel 428 such
that when the locking mechanism is unlocked, the plunger is
spring-ejected from the channel. In the depicted embodiment, the
button 518 is positioned on the side of the arm 512 such that it is
not easily visible to or accessible by a child seated in the second
child seat 400. In alternate embodiments, various other forms of
release mechanism can be provided.
[0088] The detachable tray 530, shown in FIGS. 34-38, can be
detachably coupled to the base tray 510. The detachable tray 530
has a generally rectangular shape with a substantially flat upper
tray surface 512. The upper tray surface can include one or more
partitioned sections 534 that can be used to hold food and other
items, such as children's toys. The sections 534 can also be used
as cup holders. In example embodiments, the cup holder 534 has a
generally teardrop shape which can help prevent a square object,
such as a juice box, from becoming wedged in the cup holder. The
detachable tray 530 can include a lip around its periphery. In the
depicted embodiment, the detachable tray 530 includes a scooped lip
536 along the portion of the tray proximal to a child seated in the
second child seat. The scooped lip 536 is formed from a curved edge
that forms an inward facing wave-shape designed to assist an infant
in gathering and scooping objects, such as small food. The bottom
surface 538 of the detachable tray 530, depicted in FIG. 35,
includes two spring biased attachment ribs 550 pivotally mounted to

and 38. In alternate embodiments, another coupling mechanism can be
used.
[0089] The detachable tray 530 can optionally also include an
auxiliary tray 540 positioned within the detachable tray in a
drawer-like configuration that permits a user to slide the
auxiliary tray into and out of view, as shown in FIG. 39. The
auxiliary tray 540 is located at a distal or front end of the tray
assembly 500 or is otherwise situated such that a child seated in
the second child seat 400 cannot access items on the auxiliary
tray. The auxiliary tray 540 is designed to provide space for a
parent or other adult caregiver to store and stage items out of
reach and/or view of the child or infant. The auxiliary tray 540
can include partitioned sections 542 for holding utensils, food,
toys or other items. In example embodiments, the auxiliary tray 540
is detachable from the detachable tray 530 so that the caregiver
can clean the tray or prepare food and drink at a different
location before recoupling to the detachable tray. In other
embodiments, the auxiliary tray 540 includes a liner that can be
detached for cleaning. The auxiliary tray 540 can include a lip on
the bottom surface to facilitate sliding the auxiliary tray away
from the detachable tray 530.
[0090] The tray assembly 500 can optionally also include a liner
560 dimensioned to nest over the upper surface 532 of the
detachable tray 530. The liner 560 can be removed from the
detachable tray for cleaning and is preferably formed from a
