Rapid-entry footwear having a rotating tongue
A rapid-entry shoe with a rotating tongue having an open configuration for ease of donning or doffing by a foot and also having a closed configuration for retention of the foot.
1. A rapid-entry shoe comprising:
a sole portion;
an upper coupled to the sole portion, an inner surface of the upper defining a volume for receiving a foot of a user; and
a rotating tongue, the rotating tongue coupled to the upper at a medial hub point and a lateral hub point aligned along a hub axis extending through the upper, and the rotating tongue comprising a tongue forward portion positioned forward the hub axis and a tongue rear portion positioned rearward the hub axis;
wherein the rotating tongue has an open configuration and a closed configuration;
wherein, in the open configuration, the tongue forward portion is rotated downward toward the sole portion about the hub axis to at least partially bisect the volume, and the tongue rear portion is rotated upward away from the sole portion about the hub axis to expand an opening to the volume to facilitate easy entry of the foot; and
wherein, in the closed configuration, the tongue forward portion is rotated upward away from the sole portion about the hub axis by the foot entering the opening to the volume to no longer at least partially bisect the volume, and the tongue rear portion is rotated downward toward the sole portion about the hub axis to narrow the opening to the volume to facilitate securement of the foot.
2. The rapid-entry shoe of claim 1 , wherein the rotating tongue is stable in the open configuration and in the closed configuration.
3. The rapid-entry shoe of claim 2 , wherein shoe further comprises an elongated element having a first end coupled to the rotating tongue at a coupling point and a second end coupled to the sole portion or the upper, wherein the first end is not coupled to the upper.
4. The rapid-entry shoe of claim 3 , wherein the elongated element does not intersect with the hub axis in either the open configuration or the closed configuration.
5. The rapid-entry shoe of claim 4 , wherein the elongated element is longer in the open configuration than in the closed configuration, and wherein the hub axis is forward relative to the coupling point in the closed configuration and rearward relative to the coupling point in the open configuration.
6. The rapid-entry shoe of claim 4 , wherein the elongated element is shorter in the open configuration than in the closed configuration, and wherein the hub axis is rearward relative to the coupling point in the closed configuration and forward relative to the coupling point in the open configuration.
7. The rapid-entry shoe of claim 4 , wherein the elongated element comprises a plurality of positive features to selectively engage with one or more of a plurality of corresponding negative features coupled to the upper to selectively lock the rotating tongue in the open configuration or the closed configuration.
