Abstract
A collapsible hand trolley includes a frame having manual gripping handles t its upper end, and a support plate at its lower end. A pair of wheel carriers is also mounted on the lower end of the frame. The trolley can be folded to a storage condition by pivoting the wheel carriers about generally vertical axes, and pivoting the support plate about a generally horizontal axis. When the wheel carriers have been unfolded to an operative position, a connection rod pivotably mounted to the frame is pivoted about a generally horizontal axis to a securing position between the wheel carriers in order to pre vent the wheel carriers from moving to their folded positions.
Claims21
A collapsible hand-operated trolley comprising:
- a frame;
- a support plate mounted on a lower portion of said frame and swivelable about a substantially horizontal first axis between folded-down and folded up positions;
- manual gripping portions disposed on an upper portion of said frame;
- a pair of horizontally-spaced wheel carriers disposed at a lower end of the frame, each wheel carrier being rotatable about a substantially vertical second axis between a folded-out operable position and a folded-in storage position;
- and
- a connection rod mounted to the frame for rotation about a substantially horizontal axis oriented substantially parallel to said first axis between a securing position wherein it extends between said wheel carriers when said wheel carriers are disposed in said folded-out positions, to prevent said wheel carriers from being folded-in.
