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.
Claims20
A hurdle assembly comprising:
- a base,
- two upright members, one upright member fixed on opposite sides of the base,
- a cross bar suspended between the two uprights, the cross bar having a first bar member and a second bar member,
- a corner pivot pivotably supporting a respective bar member on a respective upright member, the bar members being substantially perpendicular to the uprights, and
- an attachment member releasably securing the first and second bar members together by a friction frictional engagement,
- wherein a striking force on the cross bar member causes a release of the frictional engagement of attachment member from at least one bar member and a separation of the two bar members, with the two bar members pivoting on their corner pivot about a vertical axis of their respective upright members.
A hurdle assembly comprising:
- a base,
- two upright members, one upright member fixed on opposite sides of the base, and
- a cross bar suspended between the two uprights, the cross bar having a first bar member and a second bar member each pivotably supported on a respective upright member, and linearly aligned between their pivot mountings;
- an attachment member inserted into projected ends of the two bar members and frictionally engages therein, the attachment member creating the linearly aligning of the bar members,
- wherein a striking force on the cross bar member causes a release of the frictional engagement of the attachment member with at least one bar member and a separation of the two bar members, and each bar member pivoting about their respective upright member.
A cross bar assemble to be attached to the uprights of an existing hurdle assembly, the cross bar comprising
- a first bar member and a second bar member,
- a pair of corner members, one bar member attached to a respective corner member,
- an attachment member frictionally and releasably securing the two bar members in an end-to-end linear alignment, between the two corner members, and
- a pivot attachment formed as part of at least one corner member, the pivot attachment for rotationally mounting the corner member to an existing upright member, such that the corner member and its attached bar member is capable of rotation about a vertical axis of the upright member,
- wherein a striking force on the frictionally secured bar members causes a separation of the attachment member from at least one bar member so as to permit the rotation of the corner member and its associated bar member about the axis of the upright member.
