FIELD OF THE INVENTION

A child's seat, more specifically a child's seat capable of engaging a wheeled luggage container.

BACKGROUND OF THE INVENTION

Applicant's invention relates to luggage containers and children's seats and a unique combination thereof. Recently, luggage containers have become popular, which luggage containers often include at least a pair of wheels along a bottom edge thereof and a handle, frequently an extensible handle, engaging an upper surface thereof. The handle may be extended from the end of the luggage and the luggage tilted to form an oblique angle with a support surface such as an airport floor. This allows the easy wheeling of luggage across an airport, even heavy luggage, since the floor is supporting much of the weight of the luggage where the luggage wheels meet the floor. When the traveler reaches their destination, the extendable handle may be retracted back into a suitable pocket along a wall of the luggage container. One such suitcase is manufactured by Atlantic. Other similar luggage containers are manufactured by Skyway, Samsonite and other leading luggage container manufacturers.

Applicant has recognized a problem that frequently occurs when a family is traveling with young children. This problem manifests itself in the often long journey through an airport to the desired gate when the adults must contend with luggage and small children in a crowded, noisy, confusing atmosphere. Applicant recognized that it would help if a child could be confined, in a convenient way so as to prevent the child from wandering off. However, the customary wheeled stroller represents a significant amount of bulk merely for the convenience of confining a child to a wheeled conveyance during movement through an airport. Applicant has discovered the unique invention disclosed and contained herein, which novel invention provides a folding child's chair that in a folded position will store conveniently within a luggage container but in an expanded position will engage the wheeled luggage container in a manner such that the chair is supported by the luggage itself and placing the child's weight over the wheels of the container.

SUMMARY OF THE INVENTION

What Applicant provides is a foldable child's seat capable of engaging a luggage container, such as a luggage container having at least a pair wheels. More specifically, the handle or top of the luggage container acts as a support brace for engaging the foldable chair. The foldable chair includes a loop for engaging the extendable handle or to the top of the luggage container and has a seat portion including a seat back and a seat bottom that are hingedly engaged so as to lay perpendicular to one another and provide support for the buttocks and the back of the child.

In its simplest embodiment, Applicant provides two platforms, hingedly engaged to one another so that a first platform, for example a seat bottom platform, may lay perpendicular to a second platform, for example a seat back platform. From the seat back platform is hingedly engaged a luggage attachment member, which member is designed and adapted to extend generally perpendicular to the seat back platform when in a use position.

In another preferred embodiment, Applicant's seat includes a seat bottom frame and a seat back frame, the two frames typically made of aluminum tubing and being generally rectangular and/or similarly dimensioned. The two frames are pivotally engaged to one another and include a cover, the cover typically being cotton, woven fabric, plastic or any suitable flexible member. A hinge engages the two platforms so that they may be pivoted one respect to the other so they lay in a folded position parallel to one another and in an extended position perpendicular to one another. The frames may support the seat cover to provide a convenient resting place for the child or other weight. From the seat back portion, a support loop may be pivotally engaged so it can lay, in a first or storage position, parallel to the two platforms of the seat and in an extended or use position, perpendicular to the seat back platform.

A number of advantages are achieved by Applicant's novel seat and the combination of Applicant's novel seat with a wheeled, handle extendable luggage container. Those advantages include effectively securing a child to the wheeled luggage container for ease of transport through, for example, an airport. The advantages include simplicity and compactness, such that the foldable child's luggage chair is easy to travel with. The advantages of Applicant's novel design include ease in adapting the chair to the luggage as well as simplicity in the manufacture of the chair.

These and other advantages or objects are provided in a foldable child's seat adaptable to engagement with an extendable handle or top of a luggage container, the foldable seat including a generally rectangular seat bottom platform hingedly engaged to a generally rectangular seat back platform so that the two may fold together in a stored position when they fold out in a use position, wherein in the use position the two platforms are perpendicular to one another.

The novel child's foldable seat chair for engagement with an extendable handle or the back wall of a wheeled luggage container may also include a support loop extending from the seat back platform, which support loop has a removed end, the removed end for engagement with the extendable handle of the wheeled luggage container, the support loop foldable so that it can lay in a stored position adjacent the two platforms and in the use position can extend perpendicular to the seat back platform.

Applicants provide additional embodiments of a child's seat engageable to a luggage carrier in providing a flexible strap for engaging a luggage carrier, typically at a handle, which flexible strap also engages a fabric sling with a rigid bottom seat, for enclosing a child, typically from the waist down. The sling may have leg hole cutouts in a front wall thereof, which front wall may be supported by straps extending from the flexible luggage engaging a loop.

Yet a further embodiment of Applicants' present invention includes a child's chair with a pivotal armrest engaged to a seatback frame, the armrest foldable between a closed or nonuse position and a use position, the use position being a position in which the armrest, supported by hinges or the like, extends perpendicular from the seatback frame and provides a location for the child to rest his or her arms as they are seated in the child's chair.

In yet a further embodiment of Applicants' present invention, a pair of legs are adapted to extend obliquely outward from a lower perimeter of the chair to engage the floor to prevent a child seated in the seat with the seat engaged to an upright luggage carrier from tipping forward.

In yet another alternate preferred embodiment of Applicants' present invention, a support arm or a support frame extends perpendicularly downward from a forward edge of the seat bottom frame to engage the floor to help stabilize a seated child and prevent the seat from tipping forward as, for example, when attached to an upright luggage container. A number of configurations are provided to achieve this function, some of which include means to adjustably set the distance between the forward edge of the seat bottom frame and the floor.

In a number of embodiments discussed above, Applicants disclose various means to provide engagement from a seat assembly, comprising a seatback frame and a seat bottom frame (or platforms) with the handle, the top, or the back edge of a luggage carrier.

In yet another alternate preferred embodiment of Applicants' present invention, means are provided to engage the seat assembly, typically at an upper perimeter or edge of the seat back frame or platform, with a means to engage the body of the luggage container itself, rather than an extended handle.

In yet another alternate preferred embodiment of Applicants' present invention, a foot support brace or frame is provided, foldably articulating with the seat assembly (typically from a forward edge of the seat bottom frame) to provide a place for a child to place their feet. This foot bar assembly may incorporate an adjustable downwardly depending leg or legs which will engage the floor to provide stability to a child seated in the chair when the chair is engaged to the luggage to prevent, for example, the chair assembly tipping forward.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Reference to FIGS. 1 through 5, illustrate, at the outset, a luggage container (LC) having wheels (W) and a handle (H). The luggage container illustrated is merely representative of many similarly wheeled and handled luggage containers of the prior art, having a number of different shapes and sizes and construction designs. Applicant's novel foldable child's seat ([0031] 10) is designed, as illustrated in FIG. 1 to engage the handle and walls of the luggage container (LC) in a manner set forth below, so as to provide a comfortable, sturdy seat in which when attached to the luggage container, a child may ride.
It is seen that the general construction of the foldable child's seat ([0032] 10) includes a seat bottom frame (12) hingedly engaged to a seat back frame (14), the two frames being able to lay in a folded position adjacent one another or in an open position perpendicular to one other, the two frames covered by an L-shaped cover (22). The seat back frame (14) has a support loop (16) hingedly engaged therewith, the support loop for engaging the extendable handle of luggage container (LC) such that the loop lays along a top surface of the luggage and the seat back frame lays perpendicular the loop and adjacent, and typically flush against a sidewall of the luggage (See FIG. 1). With the seat frame extending perpendicular to the seat back and sidewall of luggage, the combination of seat back and seat frame provides support to the back and buttocks and legs of a child when the child is seated in the foldable child's seat chair (10) and the seat chair (10) is engaged to the luggage container (LC) so as to ride on wheels (W) when tilted.
Platforms may be used instead of seat bottom and seat back frames, however, a preferred embodiment of Applicant's present invention utilizes frames and fabric covers for lightness and simplicity. Indeed, reference to the figures illustrate a seat bottom frame ([0033] 12) including a front rail (12A), side rails (12B and 12C) and rear rail (12D). Seat back frame (14) may include top rail (14A), side rails (14B and 14C) and bottom rail (14D). Support loop (16) as provided may include an end rail (16A), two side rails (16B and 16C) and a rear rail (16D). A first hinge (18), such as a piano hinge or any other suitable hinge device is provided for engaging seat bottom frame (12) to seat back frame (14). This is typically done by hingedly connecting rear rail (12D) of seat bottom to bottom rail (14D) of seat back. A support loop is provided with a second hinge (20), for attaching the rear rail (16D) of the support loop to the top rail (14A) of the seat back frame.
The frame and support loop and the rails defining the frame and support loop may be manufactured from lightweight, durable aluminum tubing or any other suitable material. Cover ([0034] 22) may be L-shaped and typically includes fabric defining an outer surface (22D) and inner surface (22E) separated by sidewalls (22F), the outer surface and inner surface defining an interior space that will slip over the seat bottom and seat back frame snugly so that the sidewalls (22F) engaged the side rails and front rail of the bottom frame and the side rails and the top rail of the seat back frame so that the fabric is what supports the child's weight, especially the fabric stretched between the sidewalls of the seat bottom frame. Cover (22), therefore includes a seat bottom portion (22A) and a seat back portion (22B). Side panels (22C) have edges that engage both the seat bottom portion and seat back portion as illustrated in FIG. 2 so that the side panels position the seat back and seat bottom in perpendicular relation when the foldable seat (10) is in a use position as illustrated in FIG. 1.
Seat bottom frame, seat back frame and support loop may be folded to a closed position as illustrated in FIG. 5 and Applicant provides a suitably dimensioned fabric stow bag ([0035] 28) dimensioned for receipt of the folded chair thereinto. Other features of Applicant's novel foldable child's seat may be appreciated with reference to FIGS. 1 and 5. For example, a seat/chest belt (24) may be provided for a 2, 3, 4 or 5 point suspension system, here illustrated with a 3-point suspension system including a chest and/or seat strap (24C) and a antisubmarine strap (24B), the three straps defining a 3-point suspension system engagable at buckle (24A). A 5-point system would include a pair of shoulder straps (not shown).
The seat and/or chest belt ([0036] 24) is designed to secure the child to the seat. An adjustable seat loop or securement strap 26 is designed to the secure seat assembly to the luggage container (LC) in the manner illustrated in FIG. 1 such that the back of the seat lays snug against the sidewalls of the luggage container. However, as is apparent with reference to FIG. 1, it can be seen that Applicant can provide a seat securement strap (26) for attachment to the seat back and/or seat bottom and capable of wrapping around the walls of the luggage to hold the seat back snug against the walls of the luggage container so as to act in conjunction with the support loop to secure the foldable child's seat (10) to luggage container (LC).
FIG. 6 illustrates the use of rigid platforms ([0037] 30), (32) and a flexible cord or strap (34) in place of the rigid support loop. The cord or strap (34) may be adjustable. In this embodiment, only a single hinge (36) is necessary and side braces (38A), (38B) will hold the platforms perpendicular to one another when in use.
