A child stroller apparatus includes a first frame portion provided with a first wheel assembly, a second frame portion provided with a second wheel assembly, the second frame portion being assembled with the first frame portion for sliding movement along a lengthwise axis extending from a front to a rear of the child stroller apparatus, and a control mechanism operable to adjust a position of the second frame portion relative to the first frame portion, the control mechanism including an actuator assembled with one of the first and second frame portions, the actuator being operable to drive the second frame portion in sliding movement relative to the first frame portion for modifying a distance between the first and second wheel assemblies.

Infant carriers are stably supported and transported by being positioned on a frame set on wheels. The frame may include an infant carrier holder with a floor with a ramp and sidewalls. The infant carrier holder may be integral with the frame or may be mounted to a mounting device that can be adjusted for mounting angle or height. A handle is provided to the frame at a position that is suitable for a person in a wheelchair to grasp the frame and move the transport. A handle suitable for a standing person to grasp the frame may optionally be provided. The transport permits a person that may have difficulty carrying or transporting an infant carrier to more easily transport the infant carrier in a standing or a seated position, the latter as may be the case with a wheelchair occupant. The transport may be fastened to the wheelchair.

A multi-function stroller may comprise a lower chassis shell and an upper occupant shell connected by a quick release pivot joint that provides occupant accommodation that is secure and comfortable. In addition, the structural architecture is designed to allow safe adaptations to the axle configuration. Through flexible suspension arm mounting the suspension-hub-wheel/tire assembly can be quickly assembled/disassembled to provide alternative usage axle layouts. An ergonomic handle assembly may be coupled with the structure for pushing, pulling, towing, carrying, etc. When disassembled, the multi-function stroller can be folded into a compact storage mode. Thus, non-compromised performance, versatility, and usage functionality can be readily achieved and accomplished in a safe manner.

The invention discloses a method of manufacturing a handrail assembly including steps of 1) providing a first material layer and a second material layer, wherein the second material layer is a hot melt material; 2) stacking the second material layer on the first material layer to form a substrate layer with an integrated structure; 3) curling the substrate layer to form a handrail cover matching a handrail tube, wherein the handrail cover is a sleeve structure and the second material layer is located at an inner side of the handrail cover; 4) inserting the handrail tube matching the handrail cover into the handrail cover to form a handrail assembly semi-finished product; 5) baking the handrail assembly semi-finished product until the second material layer is completely melted; and 6) cooling the handrail assembly semi-finished product after baking to form the handrail assembly.

A collapsible child's stroller with a handle frame (30), a front wheel frame (10) and a rear wheel frame (20), mutually connected at a hinge joint (12, 22, 42) for mutual angular displacement between folded and unfolded configurations. The hinge joint has two spaced apart, parallel hinge axes, about which the frames (10, 20, 30) mutually rotate. The stroller is further provided with a locking element (43, 44) moveable between a locked position in which the frames (10, 20, 30) are locked in the unfolded configuration, and an unlocked position allowing the frames (10, 20, 30) to rotate to the folded configuration. The locking element (43, 44) moves in a direction traverse to the parallel hinge axes to better transfer loads between the frames.
