摘要： The safety stirrup disclosed herein has a strap receiving hanger bar at the upper extent of the stirrup, and a pair of laterally spaced apart side bars that depend downwardly from the hanger bar, wherein one of the side bars is pivotally connected to the hanger bar so as to be swingable, laterally outwardly with respect to the opposite side bar. One end of a footrest bar that normally bridges the lower ends of the side bars is pivotally connected to the lower end of the nonpivoted side bar, and the opposite end of the footrest bar is held by a releasable catch formed on the lower end of the pivoted side bar. A biasing spring continuously urges the pivotally mounted side bar inwardly so as to cause the catch at its lower end to retain the footrest bar in a bridging, foot supporting position. A pair of deflector plates are separately affixed, one to each side bar, and are shaped as to be forwardly and upwardly convergent so as to react to excessive, upward tilting of the boot toe of a falling rider which wedges between the deflector plates, spreading the plates and thus the supporting side bars, laterally outwardly. The resulting displacement of the lower end of the pivotally mounted side bar releases the catch that retains the footrest bar and allows the footrest bar to swing downwardly and away, safely releasing the rider's boot and foot.
摘要翻译：本文所公开的安全蹬具有在镫形件的上部范围处的带子接收衣架杆，以及一对横向间隔开的侧杆，其从衣架杆向下延伸，其中一个侧杆可枢转地连接到衣架杆，从而以相对于相对的侧杆横向向外摆动。通常桥接侧杆的下端的搁脚板的一端枢转地连接到非传动侧杆的下端，并且搁脚杆的相对端由形成在枢转侧杆。偏压弹簧向内连续地推动枢转安装的侧杆，以便使其下端的卡扣将搁脚杆保持在桥接的脚支撑位置。一对偏转板单独地固定在每个侧杆上，并且被成形为向前和向上收敛，以便对楔形在偏转板之间的下落骑手的脚趾的过度向上倾斜作出反应，从而扩展板和因此支撑侧杆横向向外。所产生的可枢转安装的侧杆的下端的位移释放保持搁脚杆的卡扣，并允许搁脚板向下和向外摆动，安全地释放骑手的靴子和脚。
