A combination crutch and knee walker device for converting between a crutch configuration and a knee walker configuration, the device consisting of:
- a pair of first support bars defined by a first mobile end and a brace end, the brace end forming two apertures;
- at least one roller disposed at the first mobile end of the pair of support bars, the at least one roller having a plurality of teeth disposed in a radial arrangement;
- a gear mechanism configured to enable selective engagement and disengagement with the plurality of teeth of the at least one roller,
- whereby the gear mechanism selectively restricts rotation of the at least one roller or enables free rotation of the at least one roller, the gear mechanism comprising a sliding link defined by a teeth end and a lever end, the sliding link configured to extend along the length of the pair of first support bars;
- a lever configured to operatively connect to the lever end of the sliding link, the lever further configured to enable displacement of the teeth end of the sliding link in and out of engagement with the plurality of teeth,
- whereby engagement of the teeth end with the plurality of teeth restricts rotation of the at least one roller,
- whereby disengagement of the teeth end from the plurality of teeth enables free rotation of the at least one roller;
- crossbar configured to traverse the pair of first support bars;
- a pair of second support bars defined by a second mobile end and a panel end, the pair of second support bars configured to pivotally engage the pair of first support bars at a hinged junction,
- whereby the pair of second support bars are configured to pivotally articulate parallel to, or at an angle relative to the pair of first support bars;
- a structural reinforcement member traversing the second mobile end of the second support bar;
- a plurality of wheels disposed at the second mobile end of the pair of second support bars, the plurality of wheels configured to enable mobility of the device;
- a pair of folding link bars disposed to extend between a generally central region of the pair of second support bars and the first mobile end of the pair of first support bars, the pair of folding link bars configured to help maintain structural integrity and relative positioning of the pairs of first and second support bars, the pair of folding link bars further configured to be in hinged communication with the pairs of first and second support bars;
- a panel configured to hingedly join with the panel end of the pair of second support bars, the panel configured to pivotally articulate in conjunction with the pair of second support bars, the panel comprising an upper surface and a bottom surface defined by a channel,
- whereby a crutch configuration forms during a parallel disposition of the panel relative to the pair of first and second support bars, and a parallel disposition of the pair of second support bars to the pair of first support bars,
- whereby a knee walker configuration forms when the panel is angled relative to the pair of second support bars, and the pair of second support bars are angled relative to the pair of first support bars;
- and
- a panel release pin configured to pass through the channel in the bottom surface of the panel, the panel release pin configured to be spring loaded,
- whereby the panel release pin creates an outward bias that restricts folding of the panel,
- whereby when an inward force is applied to the panel release pin, the panel folds freely.
