The front wheel sets are also folded. Thus the baby stroller is folded into a compact size.

Abstract: A folding structure of a baby stroller and includes two respective links which are connected to two lower ends of two handles. The links are connected to two front frames and pivotably connected with two respective slides which are pivotably connected to an X-shaped connection frame which is pivotably connected to two rear frames. When folding the baby stroller, the two handles are pushed downward to activate the slides by the links, the slides then activate the connection frame to pull the rear frames to let the stroller stand up. The handles are almost not overlapped with the front frames so as to reduce weight.

Abstract: A support member of foldable travel bed is revealed. The travel bed includes two side frames and two fastening joints. By the fastening joints being released from fastening state, a connecting rod and a vertical rod of one side frame and those of the other side frame are moved toward each other so as to fold the travel bed into two halves for storage. A pivot connector is used to connect a transverse rod, the connecting rod and the vertical rod. A stopper assembly including a slide sleeve and a link rod is arranged between the transverse rod and the vertical rod. The slide sleeve is disposed around the transverse rod while two ends of the link rod are respectively pivoted to the slide sleeve and the vertical rod. Thereby the travel bed is extended stably due to the stopper assembly.

Abstract: A crib includes two side frames, two joints, a folding unit and two links.

Abstract: A joint between a bed frame and a fabric member is revealed. The bed frame includes a plurality of vertical tubes each of which includes an assembly space with a narrow opening. A connection portion connects a plurality of positioning blocks to the fabric member and the positioning blocks are corresponding to the assembly space of each vertical tube. Thereby positioning blocks are mounted into the assembly space from one end of the vertical tube and the connection portion is extending outward through the narrow opening of the vertical tube. Each positioning block is unable to be released from the assembly space axially due to that the outside diameter of the positioning block is larger than the width of the narrow opening. Thus the fabric member and each vertical tube are connected firmly.

Abstract: A removable footrest for baby high chairs is revealed. The footrest includes locking slots respectively arranged at two sides thereof and mounted on the front tubes of the baby high chair. Each front tube is with at least one locking hole while each locking slot is disposed with a bump corresponding to the locking hole.
