Interconnecting luggage system

The present invention relates to a system of interconnecting luggage, the system comprising: a first luggage item having a handle about an upper end and rolling means about a base, and being tiltable about a rotational axis of the rolling means by the handle, a second luggage item having rolling means about a base, each of the first and second luggage items having integral mutual engagement and disengagement means configured to provide, when the first and second luggage items are mutually engaged, a substantially rigid mechanical connection that maintains the first and second luggage items in relative spatial arrangement such that when the system is in a stable arrangement the rolling means of the first and second luggage items contact an underlying planar substrate, and the first luggage item is maintained at a tilt angle relative to the underlying planar substrate.
