Abstract: A tiller assembly for steering a personal mobility vehicle. A knuckle joint for the tiller includes a base secured on the front wheel steering spindle and a knuckle element connected for limited pivotal movement on the base. A bolt connects the knuckle element to the base and also connects the tiller to the knuckle joint. A spring loaded pin on the tiller enters spaced apart openings in the knuckle element to lock the tiller to the knuckle element in any one of various positions, including an operating position and a collapsed position. Adjustment screws on the base are contacted by stop surfaces on the knuckle element to limit in both directions the pivoting of the knuckle element. This allows the tiller to float to a limited extent and also to act rigidly when the vehicle user needs to pull himself up by using the tiller. Spacer sleeves on the pivot bolt allow adjustment of the friction between the knuckle element and base without affecting the tiller.

Abstract: In a grip bar for a collapsible baby carriage, first and second portions 4 and 5 are coupled with each other by a rigid link member 28 within a joint 6, so that the first and second portions 4 and 5 symmetrically operate with respect to the joint 6.
