Carriage for moving a wheeled object

A steerable carriage (1) for moving a wheeled object (2), comprising at least one engagement device (3) configured to engage with and elevate a wheel (5) of the wheeled object (2) off the ground such that the wheeled object (2) can be moved upon displacement of the carriage (1) by transmitting a propulsion force from the carriage (1) to the wheeled object (2) via the at least one engagement device (3), wherein

• the at least one engagement device (3) is provided on a chassis (4) of the carriage (1) and comprises:
• a support device (12),
• an actuating device (13) which is movable with respect to the support device (12) to cause the wheel (5) to roll forward onto the support device (12) and be held by the support device (12) and the actuating device (13),
• the support device (12) comprises:
• a stopping member (18) movable between a folded position and a stopping position in which it is configured to stop forward motion of the wheel (5), and
• an activation member (23) located between the stopping member (18) and the actuating device (13), which activation member (23) is configured to cause the stopping member (18) to move from the folded position to the stopping position when the wheel (5) is rolled onto the support device (12),
• the stopping member (18) is pivotably supported on the chassis (4),
• the support device (12) comprises at least one lever (25) which is pivotably supported on the chassis (4) between the activation member (23) and the stopping member (18), and which is adapted to transfer force applied on the activation member (23) to the stopping member (18),
• the stopping member (18) comprises a stopping bar (19) configured to make contact with the wheel (5), said stopping bar (19) extending in parallel with or essentially in parallel with an axis of rotation (R) of the wheel (5), and at least one pivot arm (21) supporting the stopping bar (19), said pivot arm (21) being pivotably supported on the chassis (4) in front of the stopping bar (19), and
• the stopping member (18) is movable between the folded position and the stopping position via an intermediate position assumed just before the wheel (5) is elevated off ground, and the stopping member (18) is configured such that, in the intermediate position, an intersection between on one hand an imaginary plane (P1) extending in parallel with the axis of rotation of the wheel (5) along the pivot arm (21), and on the other hand a vertical plane (P2) through a centre of the wheel (5) and parallel to the axis of rotation (R) of the wheel (5), is located above the axis of rotation (R) of the wheel (5).

• the activation member (23) comprises an activation bar extending in parallel with or essentially in parallel with an axis of rotation (R) of the wheel (5),
• the support device (12) on each side of the activation bar further comprises at least one support bar (16, 17) extending in parallel with or essentially in parallel with the activation bar, and
• the support bars (16, 17) are configured to support the wheel (5) and together define an inclined plane sloping upwardly in the forward direction.
