Abstract: Disclosed is a hook-on type baby seat which primarily comprises a main body portion and a seat portion. The main body portion comprises a U-shaped arm assembly for supporting the baby seat on an upper surface of a gripped object, a pair of longitudinal arm members soldered to the U-shaped arm assembly, a pair of gripping arm members for gripping or releasing the gripped object, and a pair of elevation controlling and adjusting members for allowing the pair of gripping arm members to be upwardly and downwardly movable in the elevation direction of the longitudinal arm member. The seat portion comprises a seat cushion and a back portion hanged on the U-shaped arm member by sewing.

Abstract: A foldable mechanism for a playpen includes a connection element having substantially an U-shaped cross section with two open side faces, one front face, and one rear face, the front and rear faces being provided with a U-shaped cutout and a plurality of first openings and a plurality of second openings; a press-down block having two sides each with a side groove having a narrow portion and a enlarged open end, front and rear faces each having a groove with two closed ends, an elongated through hole passing through the front and rear faces, and a hollow center with one closed end for receiving a spring, the press-down block being attached to the connection element by a first screw passing through the through hole and pressed against the spring, such that the press-down block can be pressed down, or biased, with respect to the connection element by an external force and moved back by the spring force; and a pair of hollow rods each having therein a U-shaped reed spring with protrusions on both outer faces of t

Abstract: An improved crib structure includes a crib capable of swinging in a natural rhythm, comprising a supporting frame having an upper rectangle and lower crossbars, the upper rectangle and crossbar being connected through four vertical rails at four corresponding corners of the upper rectangle and four ends of the crossbars; a supporting block being provided on each of the four ends of the lower crossbars respectively, a receiving hole being provided on the bottom surface of the supporting blocks; a pair of swinging rail being provided between two corresponding supporting blocks, the swinging rail with both ends extending in the direction parallel to the vertical rails and the mid section extending in a shape of arch, each end of the swinging rail being detachably connected to the supporting block with a connecting device through said receiving hole.

Abstract: A single-handed folding device comprises a slidable pressing means having flanges, a rivet for slidably holding the slidable pressing means, slidable keys for performing locking operation, and wires with one end fixed to the slidable pressing means and the other end fixed to the slidable keys. While the slidable pressing means is moved with relation to the rivet, the wires will be tensioned, which in turn cause the slidable keys to be pulled to an opening position so as to loosen the locking means. Further, a spring is arranged at the center of the slidable pressing means so that a force should be exerted during pressing the slidable pressing means. In addition, the single-handed folding device further includes sliding rings to facilitate the movement of the wires.

Abstract: A lockup mechanism for an infant stroller comprises a lockup member having a protrusion at one end thereof and a cavity at the other end thereof and received in a rear leg of the stroller to be movable between a first position where the protrusion is retreated inside the rear leg and a second position where the protrusion is protruded outside the rear leg; and a spring provided in the cavity of the lockup member for biasing the lockup member towards the second position, wherein when the frame of the stroller is in the collapsed position, the rear leg can be fixed with respect to the joint by the lockup member biased toward the second position by the spring so that the protrusion of the lockup member abuts against the joint, and the rear leg can be released to rotate freely with respect to the joint by moving the lockup member from the second position to the first position against a biasing force of the spring so that the frame can be moved from the collapsed position to the operating position.

Abstract: The present application relates to a brake assembly for simultaneously holding a pair of wheels, which is used in, for example, the rear wheels of a stroller, wherein the two rear wheels are each provided with a pivotal block having a protruding brake member and pivotally connected to a wheel axle respectively. The pivotal blocks are coupled to each other by the wheel axle such that when either one of the stopping pedals is stepped down by the user, the engaging protruding elements provided on the pivotal block of both wheels are engaged between the stopping ribs of both two rear wheels and holding both wheels simultaneously.

Abstract: A safety rocker or an infant seat includes a foot piece, a support bracket, two clips, two sets of pads, an upper frame, a lower frame, an inner fastener, a torsion coil spring, an outer fastener, a bolt, a swivel head, and a seat cover. The two clips are mounted on the foot piece near the bend point in order to attach the support bracket to the foot piece. The support bracket can be detached from these two clips to fold up the rocker when it is not in use. A swinging mechanism is constructed by using the bolt to penetrate the lower frame, the inner fastener, the torsion coil spring, the outer fastener, and the support bracket. Then, the swivel head is engaged with the bolt such that the lower and upper frames can limitedly rotate about the bolt with respect to the support bracket. The swivel head can be locked by engaging the inner and outer fasteners together if the rotation of the lower and upper frames with respect to the support bracket is not intended.

Abstract: The present invention relates to a front seat reversing structure for a dual-seat baby stroller comprising a reversing lever, a locating bar, switching elements, links, arms, and a handlebar wherein the reversing lever is secured to the locating bar, the ends of the locating bar being passed through the guide slots on the ends of the seat-back frame, the seat-back frame being pivoted to the switching elements which are secured to the links, the handlebar being able to slide over the upper side-bar and an engaging element being rotatably pinned to one side of the upper-bar so as to retain the handlebar. Direction changing can be effected by pulling the reversing lever and the seat-back frame such that the position of the locating bar is changed to the opposite side of the switching elements, in connection with the arms being caused to swing by the links. When an engaging element is pressed and the handle is pulled to extend forward, the usable space of the baby stroller can be expanded.
