The present invention relates to a device that can be either towed by human force, or connected to a bicycle or a controlled device and intended to carry one or two bicycle type bike or scooter type and their user. The present invention is also intended to carry objects. The device according to the invention is also intended to transport other wheeled vehicles such as wheelchairs folded for disabled people and transport said disabled persons installed on the device outside of their wheelchair. The device is also intended to carry an unfolded wheelchair for a disabled person and its user installed in said wheelchair.

The device is also intended to carry a folded wheelchair of a disabled person and a bicycle type bike or scooter type and their user. The device can conform to occupy a minimum restricted volume to be stored, such as in the trunk of a motorized vehicle trunk.

The device can be modified in size to fit the types and the number of objects it has to carry and also to adapt to the number of passengers it has to carry.

In the state of the prior art, object-carrying devices are known which are in the form of a platform equipped with wheels cooperating with the ground and provided with an arm enabling a person to move the device by human strength. In general, the arm is rigidly attached to the device. Thus, the device moves relative to the ground and pivots along the axis of the wheels. 20 -2- These devices are not designed to carry rolling machines such as bicycles, wheelchairs for the disabled, or the one or more users of said rolling machines.

Similar devices are also known which can be towed and moved by a bicycle. In this case, the traction arm is arranged to be connected to a bicycle.

These devices are not designed to carry wheeled vehicles such as bicycles, wheelchairs for the disabled, or the user or users of said wheeled vehicles.

There are also devices for towing a single bicycle from the back of a bicycle via a mechanism establishing an articulated connection between the front wheel of a bicycle and the rear portion of a bicycle. In general, this mechanism is fixed on the axis of the hub of the rear wheel of the bicycle. Nevertheless, all the known hub axles do not make it possible to cooperate with this connecting mechanism. In addition, the towed bicycle is connected to the ground by the rear wheel and is pitched on the rear wheel. Thus, the user of the towed bicycle is not installed in the normal position of piloting and pedaling. These devices are generally unstable for the person towing the bike and the person towed and sitting on the towed bike. With this device, the person towed must necessarily hold the handlebars of the towed bicycle to avoid the risk of falling and accident. Finally, this device does not guarantee the safety of the towed person because it does not prohibit the towed person to leave the towed bicycle in the driving phase. Moreover, in the case where the towed bicycle is a rolling vehicle -3 equipped with rear stabilizers, it is necessary either to disassemble said stabilizers, or to modify the position of said stabilizers so as to prevent said stabilizers from being in contact with the stabilizer. ground. These devices are not designed to carry two bicycles, or a scooter, or a wheelchair.

In this case, only the rear wheel of the towed bicycle is in rolling contact with the ground and the front wheel is raised. With this device, the towed bike user is not installed in the normal riding and pedaling position. These devices are generally unstable for the person who tows the bike 20 and for the person towed and sitting on the towed bicycle. With this device, the person towed must necessarily hold the handlebars of the towed bicycle to avoid the risk of falling and accident. This device does not guarantee the safety of the towed person because it 25 does not prohibit the towed person from leaving the towed bicycle in the driving phase. Finally, when the two bikes are no longer connected by the device, it becomes bulky for the driver of the bicycle that previously towed the bike. In addition, in the case where the towed bicycle is a rolling vehicle equipped with rear stabilizers, it is necessary either to disassemble said stabilizers or to modify the position of said stabilizers so as to prevent said stabilizers from being in contact with the ground. .
