ABSTRACT:
A stirrup for a horse saddle has a cylindrical stirrup bolt assembly attached across an open end of the stirrup and, in a conventional fashion, the bolt assembly rests in the bottom loop of a stirrup strap which is attached to the saddle fender to hold the stirrup in place during normal use. The stirrup bolt assembly comprises an outer housing with rotatable and axially movable pins or rods which have keyed outer ends extending out the end of the housing for engaging keyed openings at the open end of the stirrup with a spring within the cylindrical housing applying a force to the pins to hold them in engagement with the stirrup keyed openings. A helically shaped slot or groove on the outer surface of the pins is engaged by fingers attached to the cylindrical housing so as the stirrup swings in an arc with respect to the stirrup strap the fingers act in the slot to apply a force in opposition to the spring force to pull the pins axially inward. If the angle of the arc of the stirrup exceeds a predetermined angle, the rods or pins are moved inward far enough so that they disengage from the openings in the stirrup so that the stirrup will fall free and thereby disengage the stirrup and the rider's foot from attachment to the saddle.
