Swivel assemblies
A swivel assembly is disclosed that allows first and second sub-assemblies to swivel with respect to one another. The assembly comprises a first component and a second component, at least one having a connection formation for connection to another object. An interconnection assembly interconnects the components such that they are free to rotate about an axis. The interconnection assembly comprises an axle secured for free rotation about the axis within a recess of the second component. The axle is retained within the recess by a bearing secured within the recess by a cap located in an opening of the recess that is directed towards the first component, the axle extending through the cap along the axis for connection with the first component.
1. A swivel assembly comprising:
a first component and a second component at least one of said first component and said second component having a connection formation for connection to another object, and
an interconnection assembly interconnecting the components such that said first component and said second component are free to mutually rotate about an axis,
wherein the interconnection assembly comprises an axle secured for free rotation about the axis within a recess of the second component, the axle being retained in the recess by a bearing secured within the recess by a cap located in an opening of the recess, the cap being secured to the second component by interengaging screw threads, the opening being directed towards the first component, and the axle extending through the cap along the axis for connection with the first component.
2. The swivel assembly of claim 1 wherein the bearing is one of a rolling element bearing, a thrust bearing and a bushing.
3. The swivel assembly of claim 2 wherein the axle has a head portion, the thrust bearing being within the recess between cap and the head portion.
4. The swivel assembly of claim 1 wherein the cap is removably located in the recess thereby allowing the first component to be exchanged for another.
5. The swivel assembly of claim 1 wherein the axle has an axial projecting part that projects from through the cap for connection to the first component.
6. The swivel assembly of claim 1 having a compressive thrust bearing located between the first and second components, such as a washer disposed surrounding the axle between the first and second components.
7. The swivel assembly of claim 1 wherein each connection formation includes one or more of a shackle, a loop, a sheave, and a snap hook.
8. The swivel assembly of claim 1 wherein the first and the second components include bosses, each connection formation being connected to or integral with a boss.
9. The swivel assembly of claim 1 having two connection formations that are functionally similar to one another.
10. The swivel assembly of claim 1 having two connection formations that are functionally dissimilar from one another.
11. The swivel assembly of claim 1 wherein one of the first component or the second component is part of a fixed structure.
12. A swivel assembly comprising:
a first component and a second component at least one of said first component and said second component having a connection formation for connection to another object, and
an interconnection assembly interconnecting the components such that said first component and said second component are free to mutually rotate about an axis,
wherein the interconnection assembly comprises an axle secured for free rotation about the axis within a recess of the second component, the axle being retained in the recess by a bearing secured within the recess by a cap located in an opening of the recess, the opening being directed towards the first component, the axle extending through the cap along the axis for connection with the first component, and the axle being is fixed to prevent mutual rotation of the axle and the first component.
13. The swivel assembly of claim 12 wherein the axle is fixed in threaded engagement with the first component.
