Abstract

A steerable carriage for moving a wheeled object comprising at least one engagement device (3) configured to engage with and elevate a wheel (5) of the wheeled object off the ground such that the wheeled object can be moved upon displacement of the carriage by transmitting a propulsion force from the carriage to the wheeled object via the at least one engagement device, wherein the at least one engagement device comprises: —a support device (12), —an actuating device (13) movable with respect to the support device such as to cause the wheel to roll forward onto the support device and be held by the support device and the actuating device, wherein the support device 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, and —an activation member (23) configured to cause the stopping member to move from the folded position to the stopping position when the wheel is rolled onto the support device.

Claims

1. 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), and

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).

2. The carriage according to claim 1, wherein, in the folded position, the stopping member (18) is positioned below a level of an upper surface (20) of the chassis (4), and, in the stopping position, the stopping member (18) projects above the upper surface (20).

3. The carriage according to claim 1, wherein the stopping member (18) is configured to make contact with a fixed frame member (28) of the chassis (4) in the stopping position, thereby preventing further movement of the stopping member (18).

4. The carriage according to claim 1, wherein the activation member (23) and the stopping member (18) are mechanically linked to transfer a force applied by the wheel (5) on the activation member (23) to the stopping member (18).

5. The carriage according to claim 1, wherein the stopping member (18) is pivotably supported on the chassis (4) and 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 the force applied on the activation member (23) to the stopping member (18).

6. The carriage according to claim 5, wherein 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).

7. The carriage according to claim 6, wherein 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).

8. The carriage according to claim 6, wherein the stopping member (18) comprises an adjustment member (29), by which an inclination of the pivot arm (21) in the stopping position can be adjusted.

9. The carriage according to claim 1, wherein 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).

10. The carriage according to claim 9, wherein 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.

11. The carriage according to claim 10, wherein the support bars (16, 17) are rotationally journalled in the chassis (4).

12. A carriage according to claim 1, wherein the carriage (1) comprises two engagement devices (3) for simultaneous engagement with two wheels (5) of a vehicle.

13. The carriage according to claim 2, wherein the stopping member (18) is configured to make contact with a fixed frame member (28) of the chassis (4) in the stopping position, thereby preventing further movement of the stopping member (18).

14. The carriage according to claim 13, wherein the activation member (23) and the stopping member (18) are mechanically linked to transfer a force applied by the wheel (5) on the activation member (23) to the stopping member (18).

15. The carriage according to claim 3, wherein the activation member (23) and the stopping member (18) are mechanically linked to transfer a force applied by the wheel (5) on the activation member (23) to the stopping member (18).

16. The carriage according to claim 2, wherein the activation member (23) and the stopping member (18) are mechanically linked to transfer a force applied by the wheel (5) on the activation member (23) to the stopping member (18).

17. The carriage according to claim 16, wherein the stopping member (18) is pivotably supported on the chassis (4) and 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 the force applied on the activation member (23) to the stopping member (18).

18. The carriage according to claim 15, wherein the stopping member (18) is pivotably supported on the chassis (4) and 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 the force applied on the activation member (23) to the stopping member (18).
