A bollard comprises an elongate outer tubular cover, an elongate inner tubular core located within the outer tubular cover, a damper located at a lower end of the inner tubular core, and a washer arranged to locate the damper against the inner tubular core. The outer tubular cover and the inner tubular core are both substantially circular in horizontal cross-section and the outer tubular cover and the inner tubular core are not connected together. The bollard further comprises one or more bolts, each bolt passing through the washer, damper and inner tubular core and into the ground.
1. A bollard comprising an elongate outer tubular cover, an elongate inner tubular core located within the outer tubular cover, a damper located at a lower end of the inner tubular core, a washer arranged to locate the damper against the inner tubular core, one or more spacing elements disposed on an external surface of the elongate inner tubular core, and one or more fixing lugs extending through the outer tubular cover, wherein
the outer tubular cover and the inner tubular core are both substantially circular in horizontal cross-section,
the outer tubular cover is able to rotate relative to the inner tubular core, and
the outer tubular cover is movable along an axial length of the elongate inner tubular core between a first position with the one or more fixing lugs disengaged from the one or more spacing elements and a second position with the one or more fixing lugs engaged with the one or more spacing elements such that removal of the outer tubular cover from the elongate inner tubular core is prevented.
2. A bollard according to claim 1 , wherein the outer tubular cover and the inner tubular core are not connected together.
3. A bollard according to claim 1 , wherein the outer tubular cover and the inner tubular core are both ground-contacting.
4. A bollard according to claim 1 , wherein the washer directly contacts the damper.
5. A bollard according to claim 1 , wherein the inner tubular core is closed at the lower end.
6. A bollard according to claim 5 , wherein the damper directly contacts the closed lower end of the inner tubular core.
7. A bollard according to claim 1 , wherein each spacing element of the one or more spacing elements comprises a substantially horizontal ring around the inner tubular core.
8. A bollard according to claim 1 , wherein the inner tubular core comprises two spacing elements on the external surface thereof.
9. A bollard according to claim 1 , wherein the outer tubular cover comprises one or more holes, each of the one or more holes having a fixing lug extending therethough.
10. A bollard according to claim 9 , wherein at least one hole is located below a spacing element and the respective fixing lug extends inside the outer tubular cover in a position below the spacing element.
11. A bollard according to claim 1 , and further comprising one or more bolts, the or each bolt passing through the washer, damper and inner tubular core and into the ground.
12. A method of fixing a bollard to the ground comprising receiving an elongate outer tubular cover, an elongate inner tubular core, a damper, a washer one or more bolts, and one or more fixing lugs, passing each bolt through the washer, damper and inner tubular core and into the ground, placing the outer tubular cover over the inner tubular core such that the outer tubular cover is able to rotate relative to the inner tubular core, and passing the one or more fixing lugs though the elongate outer tubular cover such that the outer tubular cover is movable along an axial length of the elongate inner tubular core between a first position with the one or more fixing lugs disengaged from one or more spacing elements disposed on the elongate inner tubular core and a second position with the one or more fixing lugs engaged with the one or more spacing elements such that removal of the outer tubular cover from the elongate inner tubular core is prevented.
13. The method of claim 12 further comprising rotatably positioning the outer tubular cover on the inner tubular core.
14. A method according to claim 12 , wherein the outer tubular cover and the inner tubular core are not connected together.
15. A method according to claim 12 , wherein the outer tubular cover and the inner tubular core are both ground-contacting.
16. A method according to claim 12 , wherein the washer directly contacts the damper.
17. A method according to claim 12 , wherein the inner tubular core is closed at the lower end and the damper directly contacts the closed lower end of the inner tubular core.
18. A method according to claim 12 , wherein the outer tubular cover comprising one or more holes, each hole locating a fixing lug of the one or more fixing lugs.
19. A method according to claim 18 , wherein at least one hole is located below a spacing element of the one or more spacing elements on the external surface of the inner tubular core and the respective fixing lug extends inside the outer tubular cover in a position below the spacing element.
20. A method according to claim 19 , wherein each spacing element of the one or more spacing elements comprises a substantially horizontal ring around the inner tubular core.
21. A method according to claim 19 , wherein the inner tubular core comprises two spacing elements on the external surface thereof.
22. The bollard of claim 1 wherein the outer tubular cover is rotatably positioned on the inner tubular core.
