Foldable highchair

1. Field of the Invention

The invention relates to a highchair, more particularly to a foldable highchair.

2. Description of the Related Art

As shown in FIG. 1, a conventional foldable highchair 1 includes a pair of U-shaped leg members 11 spaced apart from each other in a front-to-rear direction, a seat unit 12 mounted between the leg members 11, and a dish tray 13 mounted on the seat unit 12. To fold the highchair 1, the leg members 11 are pivoted toward each other, thereby causing the seat unit 12 and the dish tray 13 to pivot relative to the leg members 11 so as to convert the highchair 1 from an upright state to a collapsed state. However, during the folding process, independent folding operations are needed to fold the seat unit 12 and the dish tray 13, or a relatively complicated link mechanism must be employed to fold the seat unit 12 and the dish tray 13 simultaneous with pivoting movement of the leg members 11 toward each other.

Therefore, the object of the present invention is to provide a foldable highchair that can attract the attention of consumers and that is convenient to use.

Accordingly, a foldable highchair of the present invention comprises a chair frame, a seat unit mounted on the chair frame, and a latch unit provided on the chair frame.

The chair frame is in a form of a four-link mechanism, and is convertible between upright and collapsed states. The chair frame includes a base, a front leg unit, a coupling link unit, and a rear leg unit. The front leg unit has a pivot end part connected pivotally to the base, extends upwardly from the base when the chair frame is in the upright state, and further has a coupling end part opposite to the pivot end part. The coupling link unit is connected pivotally to the coupling end part of the front leg unit, and extends rearwardly and inclines upwardly relative to the front leg unit when the chair frame is in the upright state. The rear leg unit has a pivot end portion connected pivotally to the base, and is spaced apart from and is disposed rearwardly of the front leg unit. The rear leg unit extends upwardly from the base and inclines forwardly when the chair frame is in the upright state. The rear leg unit further has a coupling end portion opposite to the pivot end portion and connected pivotally to the coupling link unit.

The latch unit is operable to prevent pivoting movement of the front leg unit, the coupling link unit and the rear leg unit relative to the base, thereby locking the chair frame in the upright state. The latch unit is further operable to unlock the chair frame and permit pivoting movement of and collapsing of the front leg unit, the coupling link unit and the rear leg unit together with the seat unit on the base, thereby converting the chair frame from the upright state to the collapsed state.
