Abstract
A multipurpose hand truck has a base frame with a handle frame connected thereto and orientatable to different angular positions relative to the base frame. A pair of wheels, which support the base frame, are mounted for movement in location along the base frame and are releasably securable thereto in at least two alternative spaced apart locations. Preferably wheel support brackets have channel sections therein which are slidable lengthwise along side members of the base frame. Pivotal plates connecting the handle and base frames enable the handle frame to be stored in overlying relation to and spaced above the base frame. A front load retaining plate is invertible to form a rest support.
Claims12
A multipurpose hand truck, comprising:
- a base frame defining a lengthwise direction;
- a handle frame connected to the base frame and orientatable to different positions relative to the base frame;
- a pair of wheels;
- means for mounting said pair of wheels on the base frame to support the latter;
- said mounting means being movable in location along the base frame and releasably securable thereto in at least two alternative locations spaced apart in said lengthwise direction;
- a pair of plates connected to said base frame on opposite sides thereof and pivotal about a first axis, said handle frame also being connected to said plates and pivotal relative thereto about a second axis parallel to and spaced apart from said first axis;
- first securing means for releasably securing said plates against pivoting relative to said base frame;
- and
- second securing means for releasably securing said handle frame to said plates in different angular orientations relative to said plates.
A multipurpose hand truck, comprising:
- a base frame having two side members defining a lengthwise direction;
- a handle structure connected to said base frame at one end thereof and orientatable to different positions relative to said base frame;
- a pair of wheels mounted on an axle;
- a pair of brackets which engage said side members and are movable therealong in said lengthwise direction;
- said axle being mounted through said brackets with said wheels disposed outside said brackets;
- means for releasably securing said brackets in at least two spaced apart alternative locations along said side member;
- and
- a pair of plates pivotally connected to said base frame and releasably securable in one position, said handle structure being pivotally connected to said plates and releasably securable thereto in any selected one of a plurality of positions.
A multipurpose hand truck, comprising:
- a base frame having two side members connected by at least one transverse member;
- an end plate releasably secured to one end of said base frame, said end plate being securable in either one of two orientations to form a load retaining plate in one such orientation and a support plate for supporting said base frame in the other of said orientations;
- a pair of plates connected to said base frame at the other end thereof and pivotal relative to said base frame about a first axis;
- first securing means for releasably securing said plates in one pivotal orientation relative to said base plate;
- a handle frame by which the truck can be gripped and manipulated by an operator, said handle frame being pivotally connected to said plates and pivotal relative thereto about a second axis parallel to and spaced apart from said first axis;
- second securing means for releasably securing said handle frame in different pivotal orientations relative to said plates;
- a pair of brackets movable along said side members, each of said brackets having a channel portion in which a respective one of said side members engages and a V-shaped plate depending downwardly from said channel portion;
- means for releasably securing said brackets in at least two spaced apart alternative locations along said side members;
- and
- a pair of wheels mounted on an axle, said axle being mounted in said V-shaped plates.
