Connector device for connecting a vehicle to another vehicle, a motorized tow dolly and a vehicle modularly connectable to multiple additional vehicles

A vehicle set comprising at least:

• (i) a first vehicle comprising at least:
• multiple wheels;
• a steering assembly configured to enable steering at least of the first vehicle;
• a carrier assembly configured for carrying thereover a load;
• and
• at least one motor operatively configured for driving at least one of the wheels;
• a control unit configured for controlling the driving at least of the first vehicle;
• and
• one or more power sources;
• (ii) at least one other vehicle having multiple wheels and a carrier assembly for carrying a load thereover;
• and
• (iii) at least one connector device characterized by being configured to moveably connect vehicles to one another, each connector device comprises at least:
• an upper frame configured for connecting at a front side thereof to an upper rear part of a vehicle and for connecting at a rear side thereof to a front upper side of another vehicle;
• and
• a lower frame configured for connecting at a rear side thereof to a front lower side of the other vehicle,
• wherein all vehicles of the vehicles set are removably connectable to one another via a different connecting device,
• wherein the rear side of the upper frame is configured to pivotally connect to the front upper side of the other vehicle, about a first rotation axis, and the rear side of the lower frame is configured to pivotally connect to the front lower side of the other vehicle, about a second rotation axis that is angular in respect to the first rotation axis such that the first and second axes have a non-zero angle therebetween,
• wherein the connector device comprises at least one connecting element, for removably attaching of the lower frame to the second vehicle such as to restrict or prevent the rotation of the second vehicle in respect to the connector device about the first axis “x”, for restricting or preventing folding of the second vehicle by rotating thereof about the first axis “x” when required, by removing or loosening of the attachment of the connecting element to the second vehicle and/or to the connector device and enabling folding of the second vehicle over the connector device by tightening or attachment of the connecting element to the second vehicle and/or to the connector device.
