Abstract
A rapid-entry shoe having a rotating rear portion configured to be rotated around an axis of rotation and deflected at a fulcrum to create a stress in the rotating rear portion when the shoe is in a collapsed configuration to bias the shoe toward an uncollapsed configuration.
Claims16
A rapid-entry shoe comprising:
- a sole portion;
- an upper coupled to the sole portion;
- a rotating rear portion coupled to opposing sides of the upper through an axis of rotation;
- a fulcrum coupled to the upper and the fulcrum not coupled to the rotating rear portion;
- and
- wherein the rapid-entry shoe has an uncollapsed configuration;
- wherein the rapid-entry shoe has a collapsed configuration to facilitate donning and doffing of the rapid-entry shoe;
- wherein, in the collapsed configuration, the rotating rear portion is rotated around the axis of rotation toward the sole portion and deflected at the fulcrum to create a stress in the rotating rear portion;
- wherein the stress results from contact between the fulcrum and the rotating rear portion;
- and
- wherein the rapid-entry shoe is biased by the stress toward the uncollapsed configuration.

A rapid-entry shoe comprising:
- a sole portion;
- an upper coupled to the sole portion;
- a rotating rear portion coupled at a coupling to opposing sides of the upper through an axis of rotation;
- a plurality of fulcrums coupled to opposing sides of the upper and no fulcrum of the plurality of fulcrums coupled to the rotating rear portion;
- and
- wherein the rapid-entry shoe has an uncollapsed configuration;
- wherein the rapid-entry shoe has a collapsed configuration to facilitate donning and doffing of the rapid-entry shoe;
- wherein, in the collapsed configuration, the rotating rear portion is rotated around the axis of rotation toward the sole portion and deflected by at least one fulcrum of the plurality of fulcrums to create a stress in the rotating rear portion;
- wherein the stress results from contact between the at least one fulcrum of the plurality of fulcrums and the rotating rear portion;
- and
- wherein the rapid-entry shoe is biased by the stress toward the uncollapsed configuration.
