Abstract
Description
- The present application relates to folding chairs and, more particularly, folding high chairs for children.
- Various high chairs are commercially available, many of which may be folded to facilitate packaging, carrying and stowing. In general, such chairs are stable when in an upright, unfolded configuration, but they are not adapted to freely stand upright on a floor, the ground, a driveway or other surfaces when they are in a compact, folded configuration. Instead, such chairs must be leaned against a wall, laid flat on a floor or the like. A folding high chair that stands freely on many types of surfaces and that has a convenient carrying handle may be easily transported like a suitcase, positioned under a table or removed from a car, for example.
- Commercially available high chairs may also provide various seat restraint devices, such as a strap, to prevent the seated child from sliding forward on the seat. However, the feet of the child may become hooked on such restraints when a user places the child into or lifts the child out of the seat. Alternatively, the user must fasten the restraining device into place after putting the child in the seat and then unfasten the restraining device to remove the child.
- Accordingly, there is a need for a folding high chair that is adapted to stand freely on many types of surfaces.
- Furthermore, there is a need for a folding high chair that may easily be carried with one hand when the chair is in a folded configuration.
- Furthermore, there is a need for a folding high chair having a passive seat restraint that allows a user to put a child in and out of the seat quickly and easily.
- Furthermore, there is a need for a folding high chair that is adjustable for different sizes of children, for numerous seat heights and for different seatback angles.
- In one aspect, the folding high chair includes a carriage frame having a backrest connected thereto, a front frame pivotally connected to the carriage frame, the front frame having a seat connected thereto, wherein the carriage frame is lockable with respect to the front frame, at least two legs pivotally connected to the carriage frame, wherein each of the legs is generally U-shaped and includes a right side, a left side and a bottom portion, the bottom portions having approximately equal widths, and a fold release handle positioned on the carriage frame, wherein the fold release handle is adapted to unlock the carriage frame with respect to the front frame, thereby allowing the high chair to move from an upright configuration to a folded configuration, wherein, when the high chair is in the folded configuration, the sides of the legs are partially nested together and the bottoms of the legs are approximately adjacent to each other such that the high chair is compact and stands freely on a surface.
- In another aspect, the folding high chair is adjustable between an upright position and a folded position and includes a carriage frame having a backrest connected thereto, a front frame pivotally connected to the carriage frame, the front frame having a seat connected thereto, at least two legs pivotally connected to the carriage frame, wherein each of the legs is generally U-shaped and includes a right side, a left side and a bottom portion, the bottom portions having approximately equal widths, a kick panel pivotally connected to the front frame, the kick panel having a recess therein, and a footrest pivotally connected to the kick panel, wherein, when the high chair is in the folded position, the footrest is adapted to nest in the recess and the kick panel is adapted to nest under the seat.
- In another aspect, the folding high chair is adjustable between an upright position and a folded position and includes a carriage frame having a backrest connected thereto, a front frame pivotally connected to the carriage frame, the front frame having a seat connected thereto, at least two legs pivotally connected to the carriage frame, wherein each of the legs is generally U-shaped and includes a right side, a left side and a bottom portion, the bottom portions having approximately equal widths, and a passive seat restraint extending from the seat, wherein, when the high chair is moved from the upright configuration to the folded configuration, the passive seat restraint moves from an up position to a down position.
