An associated method for folding the stroller is also disclosed, the method for collapsing the stroller including the steps of moving the second seat from its in use position to its stowed position, and then folding the stroller.The method for erecting the stroller being the reverse of the method for collapsing this.

Abstract: A baby walker with a use-transferable upper tray comprises an upper tray, a base, a pair of side posts and a positioning mechanism. The upper tray is positioned by the positioning mechanism in a first position or a second position and being connected with a seat for accommodating a baby-occupant. The base has a rear opening that permits an elder baby to enter without obstacle to learn walking therein by grabbing the rear end of the upper tray, when the upper tray is moved to a second position from a first position. Each of the pair of side posts is connected between the upper tray and the base for positioning the baby walker in a selected height.

Abstract: A baby walker with a use-transferable upper tray comprises an upper tray (2), a base (3), a pair of side posts and a positioning mechanism (7). The upper tray (2) is connected with a seat (21) for accommodating a baby-occupant sitting thereon for feeding foods. The base (3) has a plurality of wheels (31) for contacting the ground, thereby permitting an elder baby to push and move the baby walker (10) easily. Each of the pair of side posts is connected between the upper tray (2) and the base (3) for positioning the baby walker (10) in a selected height. The positioning mechanism (7) is capable of positioning the upper tray (2) relative to the base (3) in a first position (71) and a second position (72), wherein the second position (72) is forward relative to the first position (71), when the upper tray in positioned in the second position (72), allowing the elder baby to enter and learning walk inside an opening space inside the base (3) by grabbing the rear end of the upper stay (2).

Abstract: A spill-proof training cup includes a lid with a passage housing a valve. The valve has a valve plane parallel to or forming a selected angle with the passage. The valve plane has a port and a stopping flap attached outside the port to block the port and stop liquid from flowing out. When the cup is sucked on, a pressure difference is generated to overcome the blocking force of the stopping flap and a gap is generated between the stopping flap and the port so that the liquid contained in the cup body may pass through the port. The port and the passage form an angle so that when the training cup is inverted, the liquid contained in the cup does not directly hit the stopping flap and the barrier plane of the valve can block the liquid so that the liquid does not flow out improperly.

Abstract: A connecting device for linking an auxiliary member, such as a tray or a front handrail, to a baby carrier. The connecting device is capable of making the auxiliary member pivotally movable between a usage position across the first and second side arm and a storage position in front of one of the side arm of the baby carrier. It reduces possibilities of nipping or injury to the occupant's fingers.

Abstract: A safety brake device for a stroller is disclosed. The brake device will automatically preclude the movement of the stroller when the user releases the brake handle. The brake handle is movably mounted to the stroller for being pushed down during manual propulsion of the stroller. A pulling wire connects to the brake handle for operating a brake assembly incorporating with the wheels. The brake handle is movable between a first and a second positions. In the first position without being handled by the user, the brake assembly precludes the rotation of the wheels. In the second position where the brake handle is pushed down by the user, the pulling wire actuates the brake assembly to release the brake and enables rotation of the wheels. When the user leaves the stroller, the brake handle retrieves to the first position, then the wheels are braked and precluded from rotation.

Abstract: The present invention relates to a child walker, which utilizes a circular base member and a specially designed moving device to provide the functions of tipping preventing and auto-braking. By these designs, the child walker can prevent from tipping when it passes over an edge of a floor or vicinity of stair steps and control the speed of the child walker. The moving device is connected to the bottom of the circular base member for supporting the circular base member, wherein the moving device further comprises un-directional rollers for moving to an uncertain direction, directional rollers for moving to a certain direction but with a little deviation in angle from the forward direction and a stopping means for prevent the child walker from tipping when any roller is passing over an edge of a floor and then inclining by the friction between the bottom of the circular base member and the surface of the floor.
