Abstract

A barrier (1) has a base unit (2) which is secured to the ground and a top unit (3) which may be connected at any one of four different orientations. An electronic controller (6) is mounted in a door (5) of the base unit (2) so that it may be easily accessed. A drive mechanism (35) is mounted in a modular manner in the top unit (3). It is mounted by virtue of a beam drive shaft (21) which is mounted by bearings (22) at each end to opposed side walls (20) of the top unit (3). The beam is connected to the drive shaft (21) in a symmetrical manner so that the barrier may be used for either the right side or the left side of a laneway. There is excellent support and balance in the drive mechanism because it is connected between support bearings of the beam drive shaft (21). A manual override is provided to release a clutch if an electrical fault arises. The beam has a shear plate (27) which yields to minimise damage to either the drive mechanism or a beam arm (30) in the event of an accidental impact against the beam.

Claims (5)

Claims
1. A barrier comprising a beam, a drive mechanism for causing movement of the beam between a lower closed position and an upper open position in a vertical plane, and a housing, characterised in that, the beam (4) and the drive mechanism are connected to a beam drive shaft (21), and said beam drive shaft (21) is mounted on the housing by at least two spaced-apart bearings (22).
2. A barrier as claimed in claim 1, wherein the beam (4) and the drive mechanism (35) are connected to the beam drive shaft (21) between the bearings (22), and wherein the beam (4) is connected to the beam drive shaft (21) at a position approximately midway between the bearings (22), and wherein the beam (4) comprises a connector (26) secured to the beam drive shaft (21), a beam arm (30), and a shear coupling (25) interconnecting the beam arm (30) and the connector (26) and comprising means for yielding or breaking before the beam arm (30) or the connector with an impact against the beam (4), and wherein the connector comprises a pair of clamp plates (26) and the shear coupling comprises a weakened plate (27) clamped by the clamp plates (26) on one side and supporting the beam arm (30) on the other side.
3. A barrier as claimed in any preceding claim, wherein the drive mechanism (35) and the beam drive shaft (21) are mounted on a top unit (3) releasably secured to a ground-engaging base unit (2), and wherein the top unit (3) comprises means (15) for being releasably secured to the base housing unit (2) at any of four mutually orthogonal orientations, and wherein the base unit (2) comprises a door (10) and an electronic controller (11) is mounted on said door (10), and wherein the drive mechanism (35) comprises a motor (40) driving an output shaft (43), a drive crank arm (44), a con rod (45) connecting IE 991069 -9the drive crank arm (44) to a driven crank (46) secured to the beam drive shaft (21), and a counterbalance spring exerting counterbalancing bias on the beam drive shaft (21).
4. A barrier as claimed in claim 3, wherein the motor (40) is connected to the motor output shaft (43) via a clutch, and wherein the drive mechanism (35) further comprises a manual override mechanism (66-69) having an extemallyaccessible actuator (68).
5. A barrier as claimed in claim 4, wherein said actuator (68) comprises a coupler comprising means for sliding upon rotation of a spindle (69) which is externally accessible. 1 /7 IE 991069
