Abstract
Abstract A handcart includes a carrying frame with two longitudinal members having respective handles. The longitudinal members are coextensively juxtaposed with one another in a longitudinal direction; at least one crossbar connects the longitudinal members rigidly. A back panel is attached to the carrying frame, the longitudinal members, the crossbar and the back panel substantially defined a plane. At least one wheel supports the carrying frame rotatably. One side of a load-supporting plate is attached to the frame so as to be disposed transversely to the plane. A front panel is hingedly attached to one of the four sides of the load-supporting plate opposite the side thereof attached to the frame, and two side panels are hingedly attached to the remaining sides of the load-supporting plate, respectively. The side panels and the front and back panels are lockable to one another, respectively to form a substantially box-shaped container open at the top for carrying loads. The side panels are also symmetrically foldable on top of the load-supporting plate, and the front panel is foldable on top of the folded sidepanels and lockable thereto so as to form a substantially flat platform for carrying a load.

Claim 1
Independent Claim
225 words
A handcart comprising: a carrying frame including two longitudinal members having respective handles, said members being coextensively juxtaposed with one another in a longitudinal direction and at least one crossbar rigidly connecting said members; a back panel attached to said carrying frame, said longitudinal members, said crossbar and said back panel substantially defining a plane; at least one wheel rotatably supporting said frame; a load-supporting plate having four sides, one of said sides being attached to said frame for said load-supporting plate to be disposed transversely to said plane; a front panel hingedly attached to one of said four sides opposite said one side of said load-supporting plate; two side panels hingedly attached to the remaining sides of said load-supporting plate, respectively, said side panels and said front and back panels being lockable to one another, respectively, to form a substantially box-shaped container open at the top thereof for carrying loads, said side panels being symmetrically foldable on top of said load-supporting plate, and said front panel being foldable on top of the folded side panels and lockable thereto so as to form a substantially flat platform for carrying a load; and three extension panels for said front panel and said side panels, respectively, said extension panels being displaceable in an upward direction therefrom for forming an elongated box-shaped container open at the top thereof.
Claim 2
Dependent Claim

Dependent Claim
21 words
A handcart according to claim 1 wherein said base is hingeably attached to said front panel and said side panels, respectively.
Claim 4
Dependent Claim
34 words
A handcart according to claim 2 wherein said side panels and said front panel are formed with recesses for receiving said extension panels, respectively, said extension panels being disposed in an initial position therein.
Claim 5
Dependent Claim
30 words
A handcart according to claim 2 wherein said extension panels are flush with said side panels and said front panel, respectively, when said extension panels are in said initial position.
Claim 6
Dependent Claim
26 words
A handcart according to claim 1 wherein said extension panels are lockable to said back panel and to one another, respectively, when forming said elongated container.
Claim 7
Dependent Claim
82 words
A handcart according to claim 1 further comprising a first plurality of snap-in locks disposed on said back panel, said side panels and said front panel, for locking said back panel, said side panels and said front panel to one another, respectively, when forming the box-shaped container and a second plurality of snap-in locks disposed on said extension panels and said back panel for locking said extension panels and said back panel to one another, respectively, when forming said elongated box-shaped container.
Claim 8
Dependent Claim
78 words
A handcart according to claim 4 wherein each of said locks comprises: a plunger having a collar attached thereto; and a compression spring in contact with said plunger and wherein at least one of said panels is formed with a recess to receive said compression spring and wherein one of the remaining panels adjacent to said one of said panels is formed with a second recess to receive said plunger when the latter is in a locked position.
Claim 9
Dependent Claim
91 words
A handcart according to claim 1 wherein said front panel includes a first hinge for attachment to said load-supporting plate, a spacer plate being hingeably attached to said first hinge on one side thereof, a second hinge for attachment to said spacer plate on the other side thereof, said second hinge disposed substantially parallel to said first hinge and said front panel being hingeably attached to said second hinge, said spacer plate being of a thickness to enable said front panel to be foldable on top of said foldable side panels.
Claim 10
Dependent Claim
94 words
A handcart according to claim 1 further comprising at least one snap-in lock disposed on said side panels for locking said sidepanels together when forming said substantially flat platform, and wherein said side panels are formed with first and second tongues, respectively, said load-supporting plate is formed with a first slot, and said front panel is formed with second and third slots and a third tongue for said first and second tongues to slidably fit into said second and third slots, respectively, and for said third tongue to slidably fit into said first slot.
