Abstract

A unit usable for propelling an object, comprises a line, one end of which emerges in use from the unit, and means which when the line is drawn out from the unit automatically applies a force to the line which tends to retract the line into the unit; wherein the unit incorporates a point of attachment via which it can be assembled onto and disassembled from the object; and wherein the said one end of the line incorporates a section which when the unit is assembled onto an object and the line may be drawn out sufficiently to engage a propulsion-transmitting member of the object, causes the line to retain its engagement with the member so that as the force is applied to the line, the line will cause the member to displace and the object to be propelled.
