A stroller frame includes a seat pan, an operating handle movably coupled to the seat pan, and two opposite foldable side frame units each including a front leg, a handle rod, a rear leg that has a top end pivotally connected to the handle rod, a bottom leg that has a lower end pivotally connected to the rear leg, and a sliding basket tube that is movably coupled to said seat pan and slidably connected to said rear leg. To unfold the stroller frame, said operating handle is pushed downward to drive said seat pan to pivot downward so that an angle between said front leg and said bottom leg of each of said side frame units increases until said stroller frame is converted from a folded state to an unfolded state.

There is provided a walker apparatus having a pair of spaced-apart, upright frame members. The walker apparatus includes a seat operatively connected to the upright frame members. The walker apparatus has a backrest cantilevered from the frame members. The backrest has at least one opening extending therethrough for permitting a user's vision past the backrest when the user grips the upright frame members.

A stroller track system is used to facilitate the transporting of a stroller up and down stairs. The stroller track system includes a stroller, a left tread assembly, and a right tread assembly. The left tread assembly and the right tread assembly are mounted to a frame of the stroller and are used to engage multiple stairs while traversing a set of stairs. This allows the stroller to glide smoothly up or down the stairs. The left tread assembly and the right tread assembly each include a first track and a second track. Together, the first track and the second track allow the left tread assembly and the right tread assembly to span a larger section of a staircase. The first track is mounted to the frame through a first stroller-attaching mount. A track-securing bracket is used to mount the second track to the frame.

A stroller includes: a first stroller component and a second stroller component. At least one of the first and second stroller components is movable from a first position to a second position. The stroller also includes: a drive mechanism operatively engaged with the at least one of the first and second stroller components to move the at least one of the first and second stroller components from its first position to its second position; and a disengaging mechanism for disengaging the operative engagement between the drive mechanism and the at least one of the first and second stroller components to facilitate manual movement of the at least one of the first and second stroller components.

The present invention discloses a stroller handle lock auxiliary structure disposed in a stroller frame of a stroller. The stroller frame includes a lower frame and a stroller handle pivotally connected on the lower frame. The lower frame includes a first linking rod. The first linking rod is provided with a fitting portion protruding toward an outer side of the lower frame, and the stroller handle is provided with a reversing sliding sleeve matching with the fitting portion. The stroller handle lock auxiliary structure includes a rib that pushes the first linking rod toward the outer side of the lower frame. Compared to the prior art, the stroller handle lock auxiliary structure of the present invention is provided with the rib that pushes the first linking rod outward, and so when the stroller carries a weight, the first linking rod of the stroller frame is prevented from shifting excessively inward, allowing the reversing sliding sleeve to be smoothly fitted with the fitting portion, thereby facilitating locking of the position of the stroller handle and ensuring stability and safety. The present invention further discloses a stroller handle lock auxiliary structure.

A foldable stroller frame includes a connection unit interconnecting two opposite foldable side frame units, each of which includes a front leg and a handle rod connected pivotally to each other, and a rear leg connected pivotally to the handle rod. The connection unit includes four bottom rods each having a first end connected pivotally to a connecting seat, and a second end connected pivotally to a respective one of the front and rear legs of the side frame units. When the connecting seat is pulled upwardly from a lower used position, the second ends of the bottom rods move radially toward each other, whereby the side frame units are folded and move toward each other.
