Abstract: A child car seat attached to a dolly with the dolly having a handle attached to the dolly near the rear of the dolly. A wheel is attached to the dolly below the handle, and all components of the invention are constructed so that the overall center of gravity for the invention when a child typical of those who use child car seats occupies the child car seat will be in front of and near an imaginary vertical line drawn through the center of rotation for said wheel. Optionally, the invention includes one or more of the following: a stop placed upon the bottom of said dolly near the front of said dolly so that it will contact a surface upon which said dolly is located when said dolly is not tilted for movement, a friction-reduction device attached to the back of said handle, a second friction-reduction device attached to the bottom of said dolly, and a lock for attaching the dolly to a tray on a seat of an automobile or for attaching the child car seat to such tray when the child car seat is removably attached to the dolly.

Abstract: A moveable load-carrying assembly including a chassis (1) having a plurality of wheels (6) arranged as a first wheel set and a second wheel set, each wheel (6) being rotatable and swivellable relative to the chassis (1); the wheels (6) of the first wheel set being connected by a first linkage (21), and the wheels (6) of the second wheel set being connected by a second linkage (22); and wherein one of the wheels (6) of the second wheel set is linked to the opposite one of the wheels (6) of the first wheel set by a link (11) such that when one of the wheels (6) of the first wheel set is swivelled in one direction relative to the chassis (1), all the wheels (6) of the first wheel set swivel in that direction in unison, and all the wheels (6) of the second wheel set swivel in the opposite direction in unison. Means are included to provide three distinct modes of operation for a wheel set, the modes corresponding to straight-line travel, fully-steerable travel and a braking mode. The assembly also includes an apparatus for returning the steerable wheels to a straight-line position, comprising a first member (203) associated with a tie rod (202) operably connected to one or more steerable wheels, at least one further member (205, 206) pivotably associated with a fixed chassis member (201) and a resilient means (209) associate with the further member.
