Claims3
A shallow bollard sub-assembly for securing an area against vehicular penetration comprising:
- a base;
- an input member secured to the base and extending vertically from the base, wherein the input member is configured and arranged to transfer an impact to the base when a vehicle strikes the input member;
- and
- at least three leveling legs connected to the base to position the base above a supporting surface, wherein each of the leveling legs is individually adjustable to alter an elevation of a respective portion of the base relative to the supporting surface;
- wherein each of the leveling legs comprises:
- a foot member adapted to engage the supporting surface;
- and
- an adjusting member secured to one of the foot member and the base and movably engaged with the other of the foot member and the base such that an elevation of the respective portion of the base relative to the supporting surface changes upon movement of one of the adjusting member and the foot member relative to the base;
- wherein the adjusting member includes a bolt having a head at one end thereof and a threaded stud extending from the head;
- wherein the base includes a nut engaging the threaded stud and fixed to the base;
- and
- wherein the foot member includes:
- a hollow pipe having first and second open ends;
- a pad connected to and closing one of the first and second open ends of the hollow pipe;
- and
- a first washer secured to the other one of the first and second ends of the hollow pipe, wherein the threaded stud passes through the first washer and extends into the hollow pipe;
- and
- wherein the adjusting member further comprises a second washer connected to an end of the threaded stud opposite the head and captured in the hollow pipe between the pad and the first washer.
