A compact trailer (1) comprising a connecting element (13) that can be associated with a frame of a bicycle or motorcycle, and a cart (2) that has a loading bed (3) and an edge provided with at least two mutually opposite side walls (6) with which respective wheels (7) for moving the trailer resting
A compact trailer (1) comprising a connecting element (13) that can be associated with a frame of a bicycle or motorcycle, and a cart (2) that has a loading bed (3) and an edge provided with at least two mutually opposite side walls (6) with which respective wheels (7) for moving the trailer resting on the ground (S) are associated so that they can rotate about respective axes that are transverse to the direction of advancement (A) of the trailer (1). A recessed cavity (8) is provided on each one of the two side walls (6) and at least partially accommodates the respective wheel (7). Each cavity (8) has a depth that is at least equal to the axial space occupation of the respective wheel (7) accommodated inside it, so that in plan view the wheels (7) do not protrude from the outline of the cart (2).

1. A compact trailer (1) comprising a cart (2) and a connecting element (13) attached to the cart (2), whereinthe connecting element (13) is adapted for connecting the connecting element (13) with a bicycle or a motorcycle for towing the cart andthe cart (2) has a loading bed (3) and an edge provided with at least two mutually opposite side walls (6), wherein each side wall (6) has a movement wheel (7) rotatably mounted thereon such that the axis of rotation of each movement wheel (7) is transverse to the side wall (6) on which the movement wheel (7) is rotatably mounted and each movement wheel (7) extends below the side wall (6) on which the movement wheel (7) is mounted for supporting said cart (2) and moving the cart (2) in a direction of advancement (A) when each wheel (7) is resting on the ground (S),each side wall (6) has a recessed cavity (8) which partially accommodates the movement wheel (7) rotatably mounted on the side wall (6), said recessed cavity (8) having a depth in the axial direction of the axis of rotation of the movement wheel (7) rotatably mounted on the side wall (6) that is at least equal to the axial space occupation dimension (D) of the movement wheel (7) rotatably mounted within the recessed cavity (8), so that in plan view said movement wheels (7) do not protrude beyond the outer periphery of said cart (2),said cart (2) comprises a front wall (10) and a rear wall (11), wherein the front wall (10) and rear wall (11) are each interposed between said two side walls (6), each have main opposite sides that are pivoted to contiguous sides of said side walls (6),said bed (3) comprises at least a lateral portion (4) and a central portion (5), wherein the lateral portion (4) is integral with at least one of said two side walls (6) and the central portion (5) is pivotably attached to said lateral portion (4), andsaid cart (2) being movable between (A) a configuration for use, in which said central portion (5) is arranged on a plane that is substantially parallel to the ground (S) and transverse to said two side walls (6) and said front wall (10) and said rear wall (11) are arranged along planes that are substantially transverse to said two side walls (6) and (B) an inactive configuration in which said central portion (5), said front wall (10) and said rear wall (11) are each pivoted, at least partially, toward at least one of said two side walls (6) and said two side walls (6) are mutually closer to each other than in said configuration for use. 2. The trailer (1) according to claim 1, wherein said cart (2) has a space occupation dimension (D) in plan view, transversely to said advancement direction (A), that is comprised substantially between 0.4 and 0.6 meters. 3. The trailer (1) according to claim 1, further comprising two auxiliary wheels (12) associated with said bed (3), said two auxiliary wheels (12) and said two movement wheels (7) having an identical distance between a respective point of contact with the ground (S) and said bed (3). 4. The trailer (1) according to claim 3, further comprising at least one pusher handle (14) associated with said rear wall (11) for pushing said trailer (1) when the cart (2) is not engaged with a bicycle or motorcycle and resting on said two movement wheels (7) and said two auxiliary wheels (12). 5. The trailer (1) according to claim 1, wherein said connecting element (13) is associated with said bed (3) in a downward facing region. 6. The trailer (1) according to claim 1, further comprising an electric motor associated with each said movement wheel (7), said electric motor being associated with, and actuatable by, a first actuator (15) arranged proximate to said pusher handle (14) and a second actuator (16) associated with said connecting element (13), which can be actuated by a tow hook (100) of a moving bicycle or motorcycle engaged with said connecting element (13). 7. The trailer (1) according to claim 1, further comprising a seating element (21) that is associated with said rear wall (11), wherein the seating element (21) can be folded up when not in use. 8. A compact trailer (1) comprising a cart (2) and a connecting element (13) attached to the cart (2), whereinthe connecting element (13) can be associated with a bicycle or a motorcycle,the cart (2) has a loading bed (3) and an edge provided with at least two mutually opposite side walls (6), wherein each side wall (6) has a movement wheel (7) rotatably mounted thereon such that the axis of rotation of each movement wheel (7) is transverse to the side wall (6) on which the movement wheel (7) is rotatably mounted and each movement wheel (7) extends below the side wall (6) on which the movement wheel (7) is mounted for supporting said cart (2) and moving the cart (2) in a direction of advancement (A) when each wheel (7) is resting on the ground (S),two auxiliary wheels (12) are associated with said bed (3), said two auxiliary wheels (12) and said two movement wheels (7) having an identical distance between a respective point of contact with the ground (S) and said bed (3) andan electric motor is associated with each said movement wheel (7), said electric motor being associated with, and actuatable by, at least one first actuator (15) arranged proximate to said pusher handle (14) and a second actuator (16) associated with said connecting element (13), which can be actuated by a tow hook (100) of a moving bicycle or motorcycle engaged with said connecting element (13).
