Trailer with combined towing and centering devices

An apparatus for pulling a trailer with a motor vehicle, said apparatus comprising main towing device for coupling the lower part of the trailer to the rear of the motor vehicle and a flexible fixing device for fastening the front part of the trailer to the roof of the motor vehicle,

• said main towing device including at least one arm which is hinged at one end to a rotating shaft and fastened at the other end to a body that carries a towing head,
• a sliding device carried by said rotating shaft, said sliding device being moveable forward and backward allowing the towing head to shift vertically and longitudinally along a vertically and longitudinally oriented midplane of the trailer, and allowing the towing head to shift to the left and to the right of said midplane, whereby an operator can position the towing head onto a ball hitch on the motor vehicle,
• a locking device for said rotating shaft effectively limiting movement of the shaft when the trailer is coupled onto the vehicle for driving,
• said flexible fixing device comprising a roof-rack mountable to said motor vehicle and a centering device including a centering head mountable to the front of the trailer, said centering head being removeably attachable to said roof-rack to form an upper connection,
• said roof-rack including a bearing plate having a hole which receives and holds the centering head,
• a slide assembly adjacent to said upper connection allowing forward and backward movement of the trailer relative to the motor vehicle, and said slide assembly allowing manual alignment of the centering head with the bearing plate hole while the trailer is coupled to the motor vehicle.
