A sliding jump cup system allows for the efficient modification of jump heights comprises a sliding jump cup and a shaft that serves as a sliding support for the cup and that can be mounted onto an existing jump standard or which itself serves the purpose of a standard.

An adjustable vault apparatus for use on a ground surface includes a base and a pair of linear actuators mounted vertically at opposing sides thereof. Each linear actuator is adapted to move a bar support thereof vertically between a lowered position and a raised position. The bar supports are mutually opposing and adapted to support one end of an elongated jump bar at a bar trough thereof, by gravity. Each linear actuator moves the bar support in accordance to a control circuit electrically connected with each linear actuator and a power source. A control signal received by the control circuit, either wirelessly or by wired connection, causes the control circuit to actuate each linear actuator to either raise or lower each bar support in unison, and the jump bar.

The system and method of training an animal to jump using a variable length oxer. The oxer having one or more jump cups located on an adjustable length arm to provide for a jump of varying depth and/or height. The oxer mounts to a standard using a variety of mechanisms. The mount may comprise a jump cup. The oxer may comprise a counterweight and/or a support leg.

A hurdle has a supporting frame and two crossing rods. The two crossing rod each respectively employing a connecting joint, a spring, an engaging member, and a locking screw engageable with two opposing standing bars. The supporting frame includes the two standing bars and a horizontal aperture. The crossing rod has a hollow rod body, a soft protector jacketed onto the rod body, and a secure aperture disposed through an end of crossing rod. The connecting joint includes a hollow tubal structure with an axial hole, a connecting section with a smaller diameter is disposed at an end, a combining aperture disposed on the connecting section. An end of the spring is a hook end and another end is a screw stem having a threaded section and an inner threaded aperture, and the hook end of the spring is placed into the connecting joint through the axial hole.

A huddle assembly is provided having a base, two upright members, and a cross bar extending between the two upright members. The cross bar includes a first bar member and a second bar member. An attachment member temporarily secures the two bar members together to form a continuous bar. The two bar members are pivotably supported on a respective upright member. The temporary attachment of the two bar members permits their separation upon contact by a runner. The pivotable attachment to the uprights permits the rotation of the bar members, during separation, about a vertical axis of the upright members.

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.
