Abstract
An adjustable height training hurdle is provided for which allows variation of the height of the hurdle from near ground level up to regulation height. A slip gear is utilized to create a scissor action of the hurdle legs thus offering incremental adjustment of the hurdle height.
Claims18
A track hurdle, comprising:
- a hurdle board;
- at least two legs each having a first end and a second end;
- a gear interconnecting said at least two legs, said gear being responsive to a vertically applied force on said hurdle to pivot said legs, said gear comprising:
- a first gear member associated with a first of at least two legs;
- a second gear member associated with a second of at least two legs;
- means for joining in rotational relation said first gear member and said second gear member;
- mean for urging said first gear member against said second gear member to maintain said legs in a selected position;
- and
- means for adjustable attachment of said first leg ends to said hurdle boar to allow said vertically applied force to adjust the distance between said second leg ends and said hurdle board.

A track hurdle, comprising:
- a hurdle board having a longitudinal slot therein;
- a plurality of legs each leg having a first end and a second end;
- a fastener providing slidable attachment of said first leg ends with said longitudinal slot such that said first leg ends may be displaced along said slot;
- and
- a slip gear interconnecting said plurality of legs for pivotal movement such that pivotal leg movement results in slidable displacement of said first leg ends in said longitudinal slot and variation of the distance between said hurdle board and said second leg end.

A track hurdle, comprising:
- a hurdle board having a longitudinal slot therein;
- at least two legs each having a first end and a second end;
- a fastener providing slidable attachment of said first leg ends with said longitudinal slot such that said first leg ends may be displaced along said slot;
- a gear interconnecting said at least two legs, said gear being responsive to a vertically applied force on said hurdle to pivot said legs, said gear comprising:
- a first gear member associated with a first of at least two legs;
- a second gear member associated with a second of at least two legs;
- means for joining in rotational relation said first gear member and said second gear member;
- and
- means for biasing said first gear member against said second gear member to maintain said legs in a selected position such that said vertically applied force forces rotation of said first gear member relative to said second gear member to adjust the distance between said second leg ends and said hurdle board.
