Abstract
A bollard assembly having a post and a sleeve. The post has a cylindrical post wall forming a cavity, an insert included with in the cavity and a longitudinal passage in the post wall. The insert has a helical wedge at its lower end with a gap in the wedge. The sleeve has a cylindrical sleeve wall forming a cavity and a latch pin that is attached to the sleeve wall and extends into the cavity. The sleeve is adapted to receive the post such that the latch pin travels through the passage in the post wall and the gap in the wedge of the insert wherein the insert can then be rotated such that the latch pin and gap are no longer aligned and the latch pin prevents upward movement of the insert and post.
Claims18
A bollard assembly, comprising:
- a post comprising a generally cylindrical post wall forming a cavity, the post wall having a passage extending generally longitudinally along the post wall, and a stop plate secured to one end of the post wall and extending across the cavity;
- an insert positioned within the cavity of the post, the insert comprising a pipe, a generally penannular wedge extending radially outward from the pipe and defining a gap therein;
- and
- a sleeve comprising a generally cylindrical sleeve wall forming a cavity and a latch pin attached to the sleeve wall and extending into the cavity of the sleeve;
- wherein the sleeve is adapted to receive the post such that the latch pin travels through the passage in the post wall and the gap in the wedge of the insert when the passage in the post wall and the gap in the wedge of the insert are aligned, and the insert is rotatable within the cavity of the post such that rotation of the insert will misalign the gap of the wedge with the passage in the post wall such that the wedge prevents the latch pin from traveling through the passage.
A bollard assembly kit comprising:
- a post comprising a generally cylindrical post wall forming a cavity, the post wall having a passage extending generally longitudinally along the post wall, and a stop plate secured to one end of the post wall and extending across the cavity of the post;
- an insert positioned within the cavity of the post, the insert comprising a pipe, a generally penannular wedge extending radially outward from the pipe, and defining a gap therein;
- a sleeve comprising a generally cylindrical sleeve wall forming a cavity and a latch pin attached to the sleeve wall and extending into the cavity of the sleeve;
- a cover comprising a generally cylindrical cover wall forming a cavity, the cover wall having a passage therein, a cover plate secured to one end of the cover wall and extending across the cavity of the cover, and a cover cap secured to the end of the cover wall opposite the cover plate;
- wherein the sleeve is adapted to receive the post such that the latch pin travels through the passage in the post wall and the gap in the wedge of the insert when the passage in the post wall and the gap in the wedge of the insert are aligned, and wherein the insert is rotatable within the cavity of the post such that rotation of the insert will misalign the gap of the wedge with the passage in the post wall such that the wedge prevents the latch pin from traveling through the passage;
- and
- wherein the sleeve is adapted to receive the cover such that the latch pin travels through the passage in the cover wall.
