Abstract

An athletics hurdle includes an upper cross bar assembly and a lower cross bar assembly. A post assembly interconnects the upper and lower cross bar assemblies. The post assembly includes a lower arm assembly that is mounted on the lower cross bar, and an upper arm assembly mounted on an upper end of the upper arm assembly. Two legs extend from ends of the lower cross bar assembly so that the hurdle is supported on the legs. The post assembly is mounted on the lower cross bar to be pivotal between an operative position and an inoperative position. Pivotal displacement of the post assembly from the operative position to an intermediate position is against a bias of a biasing mechanism and pivotal displacement of the post assembly from the intermediate position to the inoperative position is with a bias of the biasing mechanism.

Dependent claims

An athletics hurdle which comprises:

an upper cross bar assembly;
a lower cross bar assembly;
a post assembly that interconnects the upper and lower cross bar assemblies, the post assembly comprising a lower arm assembly that is mounted, at a lower end, on the lower cross bar, and an upper arm assembly, the upper cross bar assembly being mounted on an upper end of the upper arm assembly, the upper and lower arm assemblies being displaceable relative to each other to change a distance between the upper and lower cross bar assemblies;
two legs that extend orthogonally from respective ends of the lower cross bar assembly so that the hurdle is supported on the legs, the post assembly being mounted on the lower cross bar to be pivotal between an operative position in which the post assembly is generally orthogonal to the legs, and an inoperative position in which the post assembly is generally aligned with the legs;
and
a biasing mechanism interposed between the post assembly and the lower cross bar assembly, the biasing mechanism being configured so that pivotal displacement of the post assembly from the operative position to an intermediate position between the operative and inoperative positions is against a bias of the biasing mechanism and pivotal displacement of the post assembly from the intermediate position to the inoperative position is with a bias of the biasing mechanism.

3 more elements

The athletics hurdle as claimed in claim 2, wherein the post assembly is pivotal with respect to the lower cross bar assembly and the biasing mechanism includes a compression spring assembly that is pivotally mounted on the lower cross bar assembly at an operatively lower end and is engaged with the lower arm assembly at an opposed upper end, an axis of rotation of the compression spring assembly being radially offset from an axis of rotation of the post assembly so that pivoting of the post assembly and the compression spring assembly towards the intermediate position compresses the spring assembly against a bias of the spring assembly, and pivoting of the post assembly and the spring assembly from the intermediate position to the inoperative position expands the spring assembly with a bias of the spring assembly.
