## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims priority from provisional U.S. Application No. 61/533,972 entitled “Convertible High Chair,” which was filed on Sep. 13, 2011 and is herein incorporated by reference in its entirety.


BACKGROUND OF THE INVENTION
1. Field of the Invention
Various embodiments of the present invention described herein generally relate to children's high chairs.
2. Description of Related Art
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. As an example, U.S. Pat. No. 7,673,934 to Bearup et al describes a high chair having a seat member and a separate infant booster seat that can be removably secured to the high chair's seat member. As such, the high chair is convertible into multiple configurations: the high chair and seat member alone, the high chair with the booster seat secured to the seat member, and the booster seat alone. When the booster seat is detached from the high chair, it must be coupled to a separate base member and can then be secured to a standard chair for use as a booster.
However, there remains a need in the art 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).
BRIEF SUMMARY OF THE INVENTION
Various embodiments of the present invention are directed to a convertible children's high chair. In various embodiments, the convertible high chair comprises: a frame configured for resting on a floor; a first child seat defining a first seating surface, the first child seat being coupled to the frame and supported above the floor; and a second child seat defining a second seating surface, the second child seat configured for being removably coupled to at least one of the first child seat and the frame. In various embodiments, the second child seat defines a base surface configured for resting directly on a support surface and supporting the second child seat on the support surface when the second child seat is decoupled from the first child seat and the frame.
In addition, according to certain embodiments of the present invention, the surface profile of the second child seat's base surface is substantially complimentary to the surface profile of the first seating surface; and the second child seat is configured such that, when the second child seat is coupled to the first child seat, the second child seat's base surface engages the first seating surface. In further embodiments, the first child seat defines upwardly extending shoulders on lateral sides of the first seating surface; and, when the second child seat is coupled to the first child seat, at least a portion of the base surface of the second child seat is positioned securely between the first child seat's shoulders.

DETAILED DESCRIPTION OF THE INVENTION
The present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art Like numbers refer to like elements throughout.
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 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 certain embodiments, the convertible high chair is adapted such that it can be converted for use by children of varying ages. For example, in one embodiment, the high chair's first child seat may be configured as a toddler seat dimensioned for toddler-age children. As such, when the second child seat is detached, the high chair functions in a first configuration as a toddler high chair. In addition, the second child seat may be configured as an infant booster seat dimensioned for infant-age children. As such, when the second child seat is coupled to the first child seat, the high chair functions in a second configuration as an infant high chair. In such embodiments, the second child seat may 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 on a separate base or support member). As such, when the second child seat is detached, it may function on its own in a third configuration as an infant booster seat. Exemplary embodiments of such convertible high chairs are described in greater detail below.
Convertible High Chair
FIG. 1 illustrates a convertible high chair 1 according to one embodiment of the present invention. In the illustrated embodiment, the convertible high chair 1 generally comprises a frame 2, a first child seat 10, and a second child seat 20. As described in greater detail below, the FIG. 1 illustrates the convertible high chair 1 in a first configuration as an infant high chair, in which the second child seat 20 is coupled to the first child seat 10 and thereby supported by the frame 2 in a high chair configuration.
FIG. 2 illustrates a second configuration in which the convertible high chair 1 is adapted as a toddler high chair (e.g., a restaurant-style high chair). In the configuration of FIG. 2, the second child seat 20 is decoupled from the first child seat 10 and removed from the high chair 1. As shown in FIG. 2, the high chair's frame 2 comprises a pair of base frame members 2a from which vertical frame members 2b extend upwardly. According to various embodiments, the frame 2 is generally configured for resting on a floor (or other support surface) in order to support the first child seat 10 in an elevated position above the floor. In the illustrated embodiment of FIG. 2, the frame 2 also includes a plurality of wheels 2c (e.g., casters) that permit the frame 2 to be rolled by a user along the floor. According to various embodiments, the wheels 2c may include brakes for selectively locking the wheels 2c and may comprise other sliding or rolling means. In addition, certain embodiments of the frame 2 may be configured to be height adjustable in order to selectively raise or lower the first child seat 10. As an example, in one embodiment, the vertical frame members 2b may be telescoping frame members.
As shown in FIG. 2, the first child seat 10 is attached to the vertical frame members 2b and supported above the support surface. In the illustrated embodiment, the first child seat 10 defines a first seating surface 11, which includes an upwardly extending crotch restraint 12 configured to prevent a child from sliding off the seating surface 11. The first child seat 10 also includes shoulders 13, which extend upwardly from lateral sides of the first seating surface 11 and function as armrests for a child seated therein. Additionally, the first child seat 10 includes a back rest 14 for supporting the back of a child seated on the first seating surface 11. A foot rest 19 is also secured to upper portions of the vertical frame members 2b to support the feet of a child seated in the first child seat 10.
In the illustrated embodiment, the first child seat's seating surface 11, crotch restraint 12, shoulders 13, and back rest 14 are generally dimensioned to accommodate a toddler-age child. As such, the high chair 1 is well suited to function as a toddler high chair in the configuration shown in FIG. 2. However, as will be appreciated from the description herein, various other embodiments of the first child seat 10 may be dimensioned for supporting children of any age.
FIG. 3 illustrates a third configuration in which the second child seat 20 is adapted as an infant booster seat. In the configuration of FIG. 3, the second child seat 20 is decoupled from the first child seat 10 and configured for use apart from the high chair 1. As shown in FIG. 3, the second child seat 20 defines a second seating surface 21, which includes an upwardly extending crotch restraint 22 configured to prevent a child from sliding off the seating surface 21. The second child seat 20 also includes shoulders 23, which extend upwardly from lateral sides of the second seating surface 21 and function as armrests for a child seated therein. Additionally, the second child seat 20 includes a back rest 25 for supporting the back of a child seated on the second seating surface 21. In certain embodiments, the back rest 25 may be reclineable and/or removable. Furthermore, the second child seat 20 includes a rear handle 29 configured to provide an easy gripping surface for a user to grasp and move the second child seat 20. In certain embodiments, the rear handle 29 may also serve as a stop for the back rest 25 and may assist a user in locating the second child seat 20 on an adult chair by spacing it an appropriate distance from the back rest of the adult chair. Additionally, according to certain embodiments, the rear handle 29 may be adapted to receive or otherwise engage the first child seat's back rest 14.
In the embodiment of FIG. 3, the second child seat 20 also includes a tray 39 coupled to the shoulders 23 and adapted to restrain a child seated in the second child seat 20. In certain embodiments, the tray 39 may be configured to pivot in a horizontal plane about one or both of the shoulders 23. However, other embodiments of the tray 39 may be alternatively constructed (e.g., the tray 39 may be removably attached to the shoulders 23 by means of snaps, hooks, or other conventional fasteners). The second child seat 20 may also be provided with a seatbelt or harness to further secure a child positioned therein.
In addition, the second child seat 20 includes a pair of storage compartments 28 on its lateral sides adjacent the second child seat's base surface 30 (shown in FIGS. 4 and 5). In the illustrated embodiment, the storage compartments 28 are configured with a hinged door 61 and are configured for storing straps 51 (e.g., as shown in FIG. 6) for use in securing the second child seat 20 to a chair 60 (e.g., as shown in FIG. 7) or other support surface when used as a booster seat. In certain embodiments, the second child seat 20 is configured such that the second child seat 20 may not be coupled to the first child seat 10 unless the storage compartments 28 are closed (e.g., as can be appreciated from the fit of the second child seat 20 in the first child seat 10 shown in FIG. 1 and the obstructing open position of the storage compartment's hinged door 61 shown in FIGS. 6 and 7). In such embodiments, this may function as a safety feature to ensure the straps 51 are contained within the storage compartments 28 when the second child seat 20 is coupled to the first child seat 10, thereby preventing the straps 51 from hanging down from the seats 10, 20 (e.g., such that a sibling or other child could grab them or they could interfere with the seats 10, 20 securely locking together).
FIG. 4 shows a bottom view of the second child seat 20 as viewed from the seat's left side, while FIG. 5 provides a bottom view of the second child seat 20 as viewed from the seat's right side. As shown in FIGS. 4 and 5, the second child seat 20 defines a bottom base surface 30. In the illustrated embodiment, the base surface 30 has a surface profile that is generally complimentary to that of the first child seat's first seating surface 11. As such, the base surface 30 is substantially flat, but includes a recessed portion 31 dimensioned for receiving at least a portion of the first child seat's crotch restraint 12. In addition, the base surface 30 includes four non-slip pads 32 positioned at corners of the base surface 30. According to various embodiments, the non-slip pads 32 may comprise rubber strips or another material suitable for gripping a support surface.
In the illustrated embodiment, the second child seat's seating surface 21, crotch restraint 22, shoulders 23, and back rest 25 are generally dimensioned to accommodate an infant-age child. As such, the second child seat 20 is well suited to function as an infant booster seat in the configuration shown in FIGS. 3-5. In particular, the second child seat's base surface 30 provides a stable platform on which the second child seat may rest when placed on a separate support surface, such a dining chair 60 (e.g., as shown in FIG. 7). As such, the second child seat 20 can be stably placed on a separate support surface without the need to be attached to or mounted on a separate base or support member. As discussed below, in the illustrated embodiment, the second child seat's base surface 30 is also dimensioned to nest within the first child seat 10, thereby providing the base surface 30 with a relatively narrow surface area profile suitable for being placed on the seating surface of an adult chair (e.g., such that the edges of the base surface 30 do not hang over the edges of a typical adult chair's seating surface). In addition, the base surface's non-slip pads 32 provide additional stability when placed on support surfaces. Moreover, the straps 51 contained in the storage compartments 28 enable the second child seat 20 to be securely attached to a chair 60 (e.g., as shown in FIG. 7) or other support surface. As will be appreciated from the description herein, various other embodiments of the second child seat 20 may be dimensioned for supporting children of any age.
As noted above, the second child seat 20 is also configured for being removably coupled to the first child seat 10 (e.g., in the infant high chair configuration of FIG. 1). In particular, as shown in FIG. 1, the second child seat's base surface 30 is dimensioned to fit within the first child seat's shoulders 13 and rest on the first child seat's seating surface 11. As the base surface 30 has a surface profile complimentary to that of the seating surface 11, the second child seat 20 fits securely on top of the first child seat 10. The base surface's non-slip pads 32 also enhance the secure fit of the second child seat 20 on the first child seat 10 by gripping the seating surface 11. In addition, the second child seat's shoulders 23 define recessed bottom surfaces 24 (shown in FIGS. 4 and 5), which are dimensioned to receive the first child seat's shoulders 13 when the second child seat 20 is coupled to the first child seat 10. This also enhances the fit between the second child seat 20 and the first child seat 10.
In the illustrated embodiment of FIGS. 3-5, the second child seat 20 also includes a locking mechanism comprising a spring-loaded ridge 27 and a release handle 26. In the illustrated embodiment, the spring-loaded ridge 27 is positioned at the rear of the second child seat 20 and is configured to engage a lip on the first child seat 10 when the second child seat 20 is coupled to the first child seat 10, thereby locking the second child seat 20 to the first child seat 10. To release the second child seat 20 from the first child seat 10, the ridge 27 can be actuated by pulling the release handle 26, which retracts the ridge 27 and enables the second child seat 20 to be removed from the first child seat 10.
As will be appreciated from the description herein, the configuration of the convertible high chair 1 enables a user to easily convert the high chair 1 between an infant high chair configuration, a toddler high chair configuration, and an infant booster seat configuration. In addition, the high chair's second child seat 20 is especially well suited for use on its own as a booster seat, without the need to be attached to additional base or support members. According to various embodiments, this ability enhances the convenience for a user in converting the high chair 1, reduces the manufacturing cost of the high chair 1, and improves the overall reliability of the high chair 1.
Various Other Embodiments
As will be appreciated from the description herein, various changes and modifications to the convertible high chair 1 are contemplated as being within the scope of the present invention. For example, as will be appreciated from the description herein, the first child seat 10 may be permanently attached to the frame 2, or removably coupled to the frame 2. In addition, in various embodiments, the second child seat 20 may configured for being coupled to the first child seat 10, the frame 2, or both when in the infant high chair configuration of FIG. 1 (e.g., where the frame defines shoulder portions of the first child seat or fully defines the first child seat).
Additionally, in certain embodiments, the bottom surface 30 of the second child seat 20 may not be complimentary to the first seating surface 11. As an example, in one embodiment, the bottom surface 30 defines protruding portions where the non-slip pads 32 are located that may act as feet for the second child seat 20. In such embodiments, the second child seat 20 may be configured to be coupled to the first child seat 10 and for use as a boost seat on its own in a manner analogous to that described above. In addition, as will be appreciated from the description herein, various features of the of the first child seat 10 and second child seat 20 described herein may be omitted in other embodiments (e.g., footrests, back rests, non-slip pads, etc.). In addition, according to various other embodiments, both of the child seats 10, 20 may be adapted for use by infants, toddlers, or young children.
