Abstract
A self re-coiling reeling assembly (1) has a pawl (12), which co-acts with a slotted cam plate (16, 17) and a sliding cam plate. The pawl (12) can arrest the re-reeling action by engagement in a slot (18, 19) in the slotted cam plate. Movement of a sliding cam plate (21) adjusts the lengths of the slots (18, 19). This adjustment determines the re-coil speed at which latching takes place. This adjustment can also prevent latching.
Claims14
An adjustable latching device for use with a spring actuated self-recoiling reeling assembly, said latching device including:
- a rotatable reeler drum;
- a reeler casing located adjacent said rotatable reeler drum, with said rotatable reeler drum being rotatable relative to the reeler casing;
- a slotted cam plate supported by said reeler casing, which cam plate:
- provides at least one latching slot, with the length of said at least one latching slot being selectively variable, and
- at least one latching pawl, which is pivotally mounted to the reeler drum and which is adapted to enter into the latching slot in the cam plate and thereby arrest rotatable movement of the reeler drum relative to the reeler disk;
- wherein the length of the slot can be selectively varied to determine the ease with which the latching pawl can arrest rotatable movement of the reeler drum relative to the reeler disk.
