Abstract: An adjustable serving tray mainly includes an anchor apparatus located on armrests at two sides of a stroller. Each armrest has an inner side with a retaining flute formed thereon. The serving tray has coupling sections on two sides, each with an anchor trough and a latch lug. In normal usage conditions, the anchor trough engages with the anchor apparatus and the latch lug is latched in the retaining flute to anchor the serving tray. By releasing the anchor apparatus, the serving tray may be slid forwards to form a larger entrance space on the stroller to seat a child. Thus the child may be seated on the rear seat without removing the serving tray to improve convenience of use.

Abstract: A foldable structure for an infant stroller has a frame of an extended length for holding one or more seats. The frame is foldable and includes a handle bracket, armrests, front wheel brackets, rear wheel brackets and a seat bracket. The seat is mounted to the seat bracket. The seat has a backrest supported by an extendable rod. The extendable rod consists of an inner rod and an outer rod. The outer rod has a longitudinal trough to allow the inner rod to slide reciprocally therein. For installation, the inner rod is inserted into the longitudinal trough of the outer rod, pivotally engaged with the armrest, and the outer rod is pivotally engaged with the seat bracket. After completing all pivotal fastening, the armrest and seat bracket form a restriction to prevent the extendable rod from separating from the structure. When the frame is folding, the extendable rod is safer to use and more appealing because of no jutting screws or pins.

Abstract: A food tray adjustment structure for a high chair to adjust the position of the food tray to suit children of different sizes includes a handle with longitudinal sections at two sides to form a biased sliding rail with a skew angle to couple with sliding docks that have coupling troughs formed with the same type of biased surfaces. The sliding docks may form a released or a latched position with coupling sections formed on the armrests at two sides of the chair. Thereby the distance between the backrest and the food tray may be adjusted to suit children of different sizes sitting on the chair.

Abstract: The structure is designed to allow an infant to ride, sit, or lie reclined on a rocker, and to be rocked back and forth, as well as to enable the changing of the rocker's angle of inclination, or the folding of the structure for storage. In the invention, the structure comprises a frontal support frame, a rear support frame, and an arc-shaped rocking frame. On the frontal support frame there is a movable sliding sleeve to which the rear support frame is connected by a hinge. With the movable sliding sleeve, the relative positions of the frontal support frame and the rear support frame may be changed, so as to adjust the frontal support frame's angle of inclination or to draw the frontal support frame close to the rear support frame for folding to facilitate storage.

Abstract: A wheel mechanism for controlling turning of the front wheel of a stroller includes a vertical axle and a latch mechanism. The upper end of the vertical axle is pivotally connected to the frame of the stroller. The lower end of the vertical axle is fixed to a horizontal axle of the wheel. The latch is movably mounted along the vertical axle and the frame and selectively moved between a released position and a locked position. When in the released position, the wheel can freely turn around the vertical axle. When in the locked position, the wheel cannot turn on the vertical axle but only rotates with the horizontal axle in a certain direction.

Abstract: A support structure for a car safety seat for installation on an extensible and retractable stroller includes a front frame, a rear frame, a handle grip and a support frame. The support structure includes a first and a second support member mounted on the support frame for supporting the weight of a car safety seat. The first support member is stationary. The second support member has two ends engaged respectively with first and second rotary disks which are turnable about the same axis and which maintain a fixed distance with the first support member. By turning the second support member, the relative distance between the first and second support member may change thereby to support car safety seats of different sizes.

Abstract: A connection device for charging electric vehicles provides direct electrical connection for an external source of electricity to charge the battery of an electric vehicle. It mainly comprises a movable charging terminal combined with a switch, both located on the body of an electric vehicle. When the charging terminal is moved into a position that enables an electrical connection with an external source of electricity, the switch is automatically moved into a position that cuts off electricity to the driving motor of the electric vehicle, rendering the electric vehicle incapable of being started during electric charging, thus preventing accidents from occurring.

Abstract: A handlebar joint, comprises a disc seat, a rotating disc and a clutch disposed between both of them and having flexible element that passes through a handlebar. In a normal coupling position, the two end of the clutch is coupled to the disc seat and the rotating disc so as to keep the handlebar relatively unmoved; and in the releasing position, the clutch does not couple with the disc seat, therefore, the handlebar can be bent. Also, in the coupling position, when the movements of the flexible element are executed, the clutch can be rotated to drive the deflectable element, so the movements cannot be influenced when the handlebar is bent.

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.
