Abstract
A combined trolley and seat unit has an inverted U-shape main frame with principal frame side members carrying ground-engaging wheels and having a main frame support rigidly fixed thereto and to a projecting bag support which carries the lower end of a bag the upper end of which is hooked by a pocket over a hook. A folding seat frame having a U-shape leg frame is pivotally carried on the main frame on the side thereof remote from the bag-like container and is movable between a folded position lying substantially parallel to the main frame and an unfolded position in which a front leg frame to which the seat frame is attached contacts the ground and the wheels are spaced from the ground to allow the unit to be used as a seat with no risk of rolling movement.
Claims8
In a combined trolley and seat unit of the type comprising:
- a main frame including tubular or rod-like rod-like frame members,
- load container support means for supporting a load container on one side of said main frame,
- a folding seat frame of tubular or rod-like members,
- means pivotally mounting said folding seat frame to said main frame on the opposite side of said main frame from said load container support means for movement between folded and unfolded positions,
- a flexible laminar seat spanning seat frame members of said seat frame,
- leg frame means of tubular or rod-like frame members,
- means pivotally connecting said leg frame means to said seat frame, and
- ground-engaging wheels,
- the improvement comprising:
- main frame support means rigidly fixed to said main frame and said container support means and projecting from said main frame downwardly towards the ground thereby forming a triangular reinforcing sub-frame on said one side of said main frame,
- means mounting said ground-engaging wheels to said main frame, and
- said wheel mounting means and said main frame support means cooperatively interacting whereby when said seat frame is in its unfolded position, said wheel mounting means holds said wheels substantially out of load-bearing contact with the ground and said main frame support means and said leg frame means carrying the weight of said main frame to permit a user to sit safely on said seat without risk of movement by rolling on said wheels, and when said seat frame is moved from said unfolded to said folded position said wheel mounting means automatically moves said wheels into contact with the ground so that the weight of said main frame is carried by said wheels and said main frame support means.
