An ambulatory device (10, fig.1) convertible between a seat having stowed-away wheels 51, which can be affixed to a bicycle (See fig.2); and a pushchair or stroller device with deployed wheels and a handle (See fig. 3). The device comprises a seat (12) and a support frame (14) to which the seat is affixed; the support frame comprising a first connector (40) pivotally connected to the seat; a rear undercarriage portion (18) rigidly connected to the first connector; a front undercarriage portion (16) pivotally connected to the first connector; and a handle 20 pivotally connected to the seat. The handle is operatively connected to the first connector by a first linkage 50, and to the front undercarriage portion by a second linkage 100,101,102. Rotation of the handle actuates the device between buggy and child seat configurations (transition shown in figs 4 to 7). |
