Abstract: A foldable highchair includes 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 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 to the collapsed state.

Abstract: A stroller includes a tubular member disposed between left and right wheel axles and extending along a rotating axis, a linking rod rotatably mounted in the tubular member and having two linking ends which extend outwardly of the tubular member to connect with two brake control seats, a brake pedal rotatably mounted on the tubular member and extending rearwardly to be connected to the linking rod by a coupling member such that treading of the pedal forces the coupling member to turn so as to synchronously rotate the brake control seats between non-actuating and actuating positions. Two braking mechanisms are mounted between the brake control seats and the wheel axles. Each braking mechanism has a braking member moved toward a wheel when the brake control seat is turned to the actuating position so as to restrain rotation of the wheel relative to the wheel axle.

The insertable portion is brought to engage the first coupling portion in the upright direction when the coupling member is in the normal position. The insertable portion is brought to engage the second coupling portion in the upright direction when the coupling member is in the alternate position. A locking member is disposed to releasably retain the coupling member in the normal or alternate position.

Abstract: A stroller has a direction-limiting device including a direction-limiting element movable relative to a stroller frame between a limiting position, where the direction-limiting element is inserted into a limiting hole in a wheel-supporting member of a wheel unit so as to prevent rotation of the wheel-supporting member relative to the stroller frame, and a release position, where the direction-limiting element is removed from the limiting hole so as to permit the rotation of the wheel-supporting member relative to the stroller frame. A control device includes an adjusting member disposed on an upper portion of a handle unit of the stroller frame, and a pull cord disposed between the adjusting member and the direction-limiting element. The adjusting member is operable to move the direction-limiting element between the limiting position and the release position.
