Abstract: A child carrier frame includes a lower frame, an upper frame and a frame support. The frame may be adjusted between an upright position, for use, and a folded position. During folding, the carrier frame may be adjusted both to reduce its height and its width, such that a folded size is obtained that is smaller in at least two dimensions than a similar carrier frame folded to reduce only one of its height and width.

Abstract: A passenger carrier frame of the invention includes a lower frame member, a folding frame member, a back frame member and a frame folding control. These frame members are pivotally connected adjacent their ends to form a triangular arrangement in side view. The pivotal connections permit the frame to be folded and the frame folding control acts at a selected one of the pivotal connections to drive and lock pivotal rotation at that pivotal connection.

Abstract: A bicycle trailer hitch for securing a trailer to a bicycle, the trailer including a hitch arm and the bicycle having a rear wheel including an axle with an axis of rotation and a frame, the bicycle trailer hitch comprising: a hitch ball including a base end connectable to the trailer hitch arm, an opposite end formed as a ball end and a intermediate portion extending therebetween; and a bicycle-mounted hitch portion mountable on the bicycle and including a socket formed to removably retain the ball end of the hitch ball, the socket including an open end, sized to permit the ball end of the hitch ball to pass therethrough and a retainer end formed to retain the ball end therein, the open end being positioned at the forward end of the socket and the retainer end positioned at the rear of the socket such that the ball end is retained in the retainer end when the hitch arm of the trailer is extending out from the hitch behind the bicycle.

Abstract: A stroller is described that is foldable and includes a tracking adjustment mechanism. The stroller is folded by pivoting the main frame members about one pair of main connecting brackets. Handle height adjustment can be made at the bracket. Some foldable frame cross members are formed of cable, rather than tubing to reduce the weight and folded size of the stroller over stroller having foldable cross members formed of tubing. A stroller having adjustable wheel spacing for tracking and stroller center of gravity adjustment is also described.
