Abstract
A footwear heel assembly coupling a top lift and heel, comprises a shaft having opposite ends, a top lift insert coupled to the top lift, a heel insert positioned in the heel, a stop positioned in the heel, and a compressible elastic member positioned in the heel between the heel insert and the stop. The shaft ends are received in the top lift insert and stop. The top lift insert and the heel insert are slidingly coupled by the shaft, and have complementary teeth configured for interlocking engagement. The compressible elastic member biases the stop away from the heel insert, and urges the top lift insert teeth toward interlocking engagement with the heel insert teeth which prevents rotation of the top lift relative to the heel.
Claims20
A heel system for coupling a heel and a top lift of a footwear, the heel system comprising:
- a top lift insert coupled to the top lift, and comprising a plurality of spaced first teeth;
- a heel insert coupled to the heel, and comprising a plurality of spaced second teeth, the first teeth and second teeth arranged in complementary configurations;
- and
- a shaft rotatably coupling the top lift insert and the heel insert;
- wherein the heel insert is slidable on the shaft to reversibly engage the first teeth with the second teeth, and the top lift insert cannot rotate relative to the heel insert when the first teeth are engaged with the second teeth.
A heel system for a footwear, comprising:
- a top lift having a top lift cavity;
- a heel having a heel bore;
- and
- a heel assembly coupling the top lift and the heel, the heel assembly comprising:
- a shaft having opposite shaft first and second ends;
- a top lift insert coupled to the top lift, and comprising a base received in the top lift cavity, a top lift insert bore sized and shaped to receive the shaft first end, and a plurality of spaced first teeth;
- a heel insert positioned in the heel bore, and comprising a channel, heel insert first and second ends, and a plurality of spaced second teeth, the channel extending through the heel insert and sized and shaped to slidably receive the shaft, and the second teeth positioned at the heel insert first end, the first teeth and second teeth arranged in complementary configurations;
- a stop positioned in the heel bore and having a stop bore sized and shaped to receive the shaft second end;
- and
- a compressible elastic member positioned in the heel between the heel insert second end and the stop, the compressible elastic member biasing the stop away from the heel insert and urging the first teeth toward engagement with the second teeth;
- wherein the top lift and heel are rotatably coupled by the shaft, the heel insert is slidable on the shaft to reversibly engage the first teeth with the second teeth, and the top lift cannot rotate relative to the heel when the first teeth are engaged with the second teeth.
