Abstract
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.
Claims22
A hurdle assembly comprising:
- a base,
- two upright members, each respective upright member fixed on opposite sides of the base,
- a cross bar suspended between the two upright members, the cross bar having a first bar member and a second bar member,
- corner members, each pivotably supporting one of the bar members on a respective upright member, the first and second bar members positioned substantially perpendicular to the respective upright member, and
- a bar attachment releasably securing the first and second bar members together and in an end-to-end alignment,
- wherein a striking force on the cross bar causes a release of the bar attachment and a separation of the two bar members, with the two bar members pivoting on their corner member about a vertical axis of their respective upright members;
- wherein the first and second bar members are made of a soft foam material, and
- wherein the first and second bar members have a hollow core and the bar attachment is positioned within the hollow core of each of the first and second bar members.

A hurdle assembly comprising:
- a base,
- two upright members, each upright member vertically positioned on opposite sides of the base,
- a pair of corner pivot members, the corner pivot members positioning a respective bar member on a respective upright member,
- each corner pivot member comprising a telescoping structure having an outer collar co-axially aligned with an inner post member formed as part of the upright member, the coaxially aligned outer collar rotationally fixing the corner pivot member to the respective upright member, and wherein the outer collar is rotational about the vertical axis of the upright member,
- a cross bar suspended between the two upright members, the cross bar having a first bar member and a second bar member, one bar member fixed to one of the corner pivot members and pivotably supported on a respective upright member by the collar member of the corner pivot member, and the first and second bar members linearly aligned between their respective pivotal supports;
- a bar attachment positioned on projected ends of the two bar members, the bar attachment releasably fixing the projected ends together and creating the linearly alignment of the first and second bar members,
- wherein a striking force on the cross bar causes a release of the bar attachment and a separation of the two bar members, and each bar member freely rotating in a horizontal plane about the vertical axis of their respective upright member.
4 more elements
A cross bar assembly to be attached to uprights of an existing hurdle assembly, the cross bar assembly comprising:
- a first bar member and a second bar member, a pair of corner members, one bar member attached to one respective corner member, wherein the bar member projects horizontally from the corner member,
- a bar attachment positioned on projected ends of the two bar members and releasably securing the two bar members in an end-to-end linear alignment, between the two corner members, and
- a corner pivot formed as part of each of the corner members, the corner pivot rotationally mounting the at least one corner member to the upright member of the existing hurdle assembly, such that the corner member is capable of rotation about a vertical axis formed by the upright member of the existing hurdle assembly, the corner pivot including a collar telescopically fixing the corner member to the respective upright member of the existing hurdle assembly for the rotation about the vertical axis of the upright member,
- wherein a striking force on the releasably secured bar members causes a release of the of the bar attachment and a free rotation of the corner pivot about the vertical axis of the upright member of the existing hurdle assembly and a rotation of the bar members in a horizontal plane.
