Abstract
A shoe having a selectively rotating cleat assembly mounted to the sole of the shoe below the ball of a wearer's foot. The rotating cleat assembly includes a core that mates with and is held in rotatable engagement by a recess in the sole of the shoe. The rotating cleat assembly is free to rotate relative to the sole when the force of impact with a playing surface is substantially normal to a central rotation axis of the cleat assembly. The rotating cleat assembly locks relative to the sole of the shoe when the force of impact with a playing surface is a predetermined angle from the central rotation axis for a given force.
Claims4
A cleated athletic shoe comprising:
- a sole having a central recess and at least one outer recess at least partially surrounding said central recess,
- an upper body attached to said sole, and
- at least one rotatable cleat assembly attached to said sole,
- said rotatable cleat assembly comprising a bearing member rotatably mounted about a rotational axis in said central recess and which remains rotatable with respect thereto when subjected to a force applied to said cleat assembly substantially along said rotational axis and a braking member attached to the bearing member and disposed in said at least one outer recess,
- said braking member being sufficiently deflectable with respect to said at least one outer recess to frictionally mate therewith to selectively prevent rotation of said rotatable cleat assembly relative to said sole during athletic play upon application of a preselected level of force to said cleat assembly not substantially along the rotation axis,
- wherein a gap is provided between said at least one outer recess and said braking member whereby said braking member remains generally free of said at least one outer recess when a force is applied generally along the rotational axis so as to permit said bearing member to abut and rotatably bear in said central recess, and whereby said braking member, in response to a force not generally along the rotational axis, will deform to sufficiently frictionally engage said at least one outer recess to prevent the cleat assembly from rotating under athletic play.

A cleated athletic shoe comprising:
- a sole having a central recess and at least one outer recess surrounding said central recess,
- an upper body attached to said sole, and
- at least one rotatable cleat assembly attached to said sole,
- said rotatable cleat assembly comprising a bearing member rotatably mounted about a rotational axis in said central recess and which remains rotatable with respect thereto when subjected to a force applied to said cleat assembly substantially along said rotational axis and a braking member attached to said bearing member and disposed in said outer recess,
- said braking member being sufficiently deflectable with respect to said outer recess to frictionally mate therewith to prevent rotation of said rotatable cleat assembly relative to said sole upon application of a force to said cleat assembly not substantially along the rotational axis;
- said cleat assembly further comprising a bottom member attached to said bearing member and said braking member and further comprising a compliant member positioned at least partially between said bottom member and said braking member, said compliant member being made from a compressible material softer than said braking member and softer than said bottom member.

A cleated athletic shoe comprising:
- a sole having a central recess aligned about a rotational axis and at least one outer recess at least partially surrounding said central recess;
- an upper body attached to the sole;
- and
- at least one rotatable cleat assembly attached to said sole;
- said rotatable cleat assembly rotatably mounted within the central recess and comprising a bearing member and a braking member attached to the bearing member;
- the bearing member being generally freely rotatably about the rotational axis in said central recess;
- the braking member being generally freely rotatable about the rotational axis when rotating in a plane substantially perpendicular to the rotational axis in response to a resultant force applied to the rotatable cleat assembly substantially along the rotational axis;
- and
- the braking member being frictionally prevented from rotating when deformed out of a plane substantially perpendicular to the rotational axis, in response to a resultant force applied to the rotatable cleat assembly, under playing conditions, which is not directed substantially along the rotational axis thereby deflecting the braking member into sufficient frictional engagement with the outer recess of the sole to prevent rotational movement of the rotatable cleat assembly relative to the sole.
