Abstract
A special duty hand truck for maneuvering folding tables and folding chairs having a wheeled base with a transverse shaft, a handle extending outwardly from said shaft, a pair of support arms mounted for pivotal movement on said shaft between an upright position extending away from said base and a folded position extending along the handle, an auxiliary arm pivotally mounted on the shaft between an upright position extending away from said base and a folded position along said handle, and standards extending down from the handle operable to engage the ground surface and provide a fulcrum for the handle which is effective to permit the wheels to be lifted off the surface when the free end of the handle is displaced towards the surface.
Claims19
A hand truck for maneuvering tables having a top and folding legs adapted when unfolded to support the table on a floor, comprising:
- a base;
- at least one floor-engaging wheel mounted on said base;
- an elongated main prop assembly having a first end pivotally mounted on said base, and a second end extending outwardly from said base and having at least two spaced apart main table perches, said assembly being capable of being pivoted from a first stored position to a second active position;
- an auxiliary prop assembly having a first end pivotally mounted on said base independently of said main prop assembly adjacent the first end of said main prop assembly and a second end extending outwardly from said base and having at least one auxiliary table perch, said auxiliary prop capable to pivot from a first stored position to a second active position;
- and
- an elongated handle, having a first end and a second end, said first end mounted on said base adjacent the first ends of said main prop assembly and said auxiliary prop assembly and extending outwardly from said base, said at least two main table perches and said at least one auxiliary table perch, when said main and auxiliary support props are in their second active positions, providing at least a three-point support for the table top.
A hand truck for maneuvering folding tables, comprising:
- a base;
- a pair of wheels journaled on said base;
- an extension extending transversely outward from said base for supporting a table in the longitudinal direction;
- a handle, said handle comprising a first shaft, having a first end mounted on said base and a second end extending outwardly therefrom, a second shaft generally parallel to said first shaft of said handle, having a first end mounted on said base and a second end extending outwardly therefrom, and a cross connection having a first end and a second end, said first end of said cross connection section connected to said second end of said first shaft of said handle, and said second end of said cross connection section is connected to said second end of said second shaft of said handle;
- a prop assembly comprising a first support shaft, having a first end and a second end, said first end pivotally mounted on said base a second support shaft, diverging slightly from said first support shaft, having a first end and a second end, said first end pivotally mounted on said base and a support strut extending between said first and second support shafts, said prop assembly capable of being pivoted from a first position generally parallel to said handle to a second position generally perpendicular to said handle, and extending outwardly from said base;
- an auxiliary support assembly comprising a third support shaft, having a first end and a second end, said first end pivotally connected to said base, and being capable of pivoting from a first position generally parallel to said handle to a second position to form a three-point arrangement with said first and second support shafts;
- a first floor support leg, mounted on said handle intermediate said first and second ends, and extending transversely therefrom;
- a second floor support leg, mounted on said handle intermediate said first and second ends, and extending transversely therefrom;
- a reinforcing strut extending between said first and second shafts of said handle;
- a socket in said reinforcing strut, for retaining said third support shaft in said first position;
- a latch, mounted on said reinforcing strut for latching said prop assembly in the first position;
- and
- a retaining bar capable of displacement from a first position to a second position, said retaining bar retaining said prop assembly when said retaining bar is in the first position, and allowing said prop assembly to pivot freely when said retaining bar is in the second position.
A hand truck for maneuvering folding tables comprising a base having wheels journaled thereon, a handle extending outwardly from said base, a transverse shaft mounted on said base, a pair of support arms mounted for pivotal movement on said shaft between an upright position extending away from said base and a folded position extending along said handle, said support arms diverging outwardly from said transverse shaft, and an auxiliary arm pivotally mounted on said base between an upright position extending away from said base and a folded position along said handle, said auxiliary arm being mounted on said base between said diverging support arms, each of said support arms and said auxiliary arm having a perch adapted in the upright positions thereof to provide a three-point support for a table.
