ABSTRACT:
A baby carriage capable of climbing stairs utilizes a tubular frame with rear legs pivotably connected to and a basket tiltably positioned on said frame.
The basket in its position is secured by a pair of pins inserted in slots in a plate fixedly positioned on the frame.
When operated on a flat surface the pivoting movement of the rear legs is checked by locking latches mounted on the frame, these latches, when necessary, can be desengaged by the operator.
