Abstract
A boom gate including a boom gate body having a first end mounted to a pivot mechanism and a second end and a controlled failure region, wherein the boom gate body comprises at least one hollow tube being substantially comprised of carbon fibre or a derivative thereof, and the controlled failure region enables the boom gate to undergo controlled failure upon receiving a high-speed impact.
Claims18
A boom gate, comprising:
- a boom gate body including a truss having a first end mounted to a pivot mechanism and a second end;
- and
- a controlled failure region within the truss of the boom gate body;
- wherein the truss comprises a plurality of hollow tubes being substantially comprised of carbon fibre and the controlled failure region enables the boom gate to undergo controlled failure upon receiving a vehicular impact,
- wherein the truss comprises:
- a first hollow tube extending in a substantially similar direction to a second hollow tube, the first hollow tube and the second hollow tube extending in a common plane;
- and
- a third hollow tube extending in a substantially similar direction to the first hollow tube and the second hollow tube,
- wherein the boom gate body is sufficiently stiff to be cantilevered from the first end and is free of a guide wire to support the boom gate body.

A boom gate, comprising:
- a boom gate body including a truss having a first end mounted to a pivot mechanism and a second end;
- a controlled failure region within the truss of the boom gate body;
- and
- a wind deflector located adjacent the truss to protect the pivot mechanism from wind,
- wherein the truss comprises a plurality of hollow tubes being substantially comprised of carbon fibre and the controlled failure region enables the boom gate to undergo controlled failure upon receiving a vehicular impact,
- wherein the truss comprises:
- a first hollow tube extending in a substantially similar direction to a second hollow tube, the first hollow tube and the second hollow tube extending in a common plane;
- and
- a third hollow tube extending in a substantially similar direction to the first hollow tube and the second hollow tube,
- wherein the boom gate body is sufficiently stiff to be cantilevered from the first end.
