Abstract
An improved tensioning system and method of restraining cargo is provided. The tensioning system is easy and quick to operate. The tensioning system is compact and minimises space within a cargo bay. The tensioning system allows a greater angular displacement of a tensioning line over conventional tensioning system, such as a ratchet and strap mechanism.
Claims26
A tensioning system (1) comprising:
- a spool (30) rotatable about a winding axis (X);
- a torque generator (10) for transmitting torque to the spool;
- and
- a brake (20) for imparting rotational resistance to the spool;
- wherein the spool comprises:
- a first hub (40);
- a second hub (50);
- and
- a pair of connecting members (60,70) interconnecting the first hub and the second hub and configured for transmitting torque between the first hub and the second hub;
- wherein the pair of connecting members are spaced apart to form a gap (G) for receiving a tensioning line (2) to be tensioned by the spool, wherein the gap is delimited by surfaces of the first hub, the second hub and the pair of connecting members;
- and
- wherein the spool comprises a winding space (S) for receiving said tensioning line when wound around the pair of connecting members (60,70), wherein a length (L1,L11) of the winding space in a direction of the winding axis is greater than a length (L2) of the gap in the direction of the winding axis;
- and
- wherein a winding surface (41) of the first hub (40) and a winding surface (51) of the second hub (50) are inclined with respect to the winding axis (X) at an angle less than 90 degrees.
