The invention relates to a transport trolley for transporting goods and/or people, especially for transporting children. Said trolley comprises a trolley frame (1) consisting of shoring elements (10, 10′, 11, 11′, 12, 12′, 13, 13′, 133) and at least two wheeled devices (2a, 2b, 2b′), provided on said frame (1) and including wheels (20a, 20b, 20b′) for rolling the transport trolley in a transport direction (T) on a ground, one of said wheeled devices, as a front wheeled device (2a) in relation to the transport direction (T) of the trolley, being arranged on the frame (1) in front of the other rear wheeled device (2b, 2b′). According to the invention, the wheelbase between the front wheeled device (2a) and the rear wheeled device (2b, 2b′) can be adjusted by means of an adjusting device (11, 11′) on the trolley frame (1). Thereby, the wheelbase, i.e. the distance between a wheel of the front wheeled device and a wheel of the rear wheeled device, can be modified if necessary. When said transport trolley is pushed by a person, for example at a running pace, a longer wheelbase of the trolley is required for achieving the necessary tilting stability.
A transport trolley for transporting goods and/or people, in particular for transporting children, having:
The transport trolley as claimed in one of the preceding claims, characterized in that at least one of the rolling devices (2a, 2b, 2b′) has a spring-mounting arrangement (21).
The transport trolley as claimed in one of the preceding claims, characterized in that the front rolling device (2a) is mounted on the trolley frame (1) such that it can be rotated about an essentially vertically arranged axis (A).
The transport trolley as claimed in one of the preceding claims, characterized in that coupling elements (16, 16′) for coupling a wheelchair are provided in the region of the supporting struts (12, 12′), in order that the transport trolley can be moved and steered by a person using a wheelchair.
The transport trolley as claimed in one of the preceding claims, characterized in that the front rolling device (2a) is articulated on the trolley frame (1) such that it can be pivoted upward and fixed in a pivoted position.
