Abstract
A hand truck includes a main frame unit configured to carry an article, two spaced-apart clamping arm units pivotally disposed on a bottom end of the main frame unit, and two elastic restoring members connected between the main frame unit and one of the clamping arm units. The clamping arm units are driven to move relative to the main frame unit between a clamped position, in which the clamping arm units are moved close to each other for clamping therebetween the article carried by the main frame unit, and an open position, in which the clamping arm units are moved away from each other. A step mechanism is pivotally disposed on the main frame unit, and is configured to be stepped on and pressed down by a foot of a user to drive the clamping arm units to move toward the open position.
Claims9
A hand truck suitable for transporting an article, comprising:
- a main frame mechanism including a main frame unit extending in a top-bottom direction and configured to carry the article, and a wheel unit connected to said main frame unit for moving said main frame unit;
- a clamping mechanism including two clamping arm units pivotally disposed on a bottom end of said main frame unit and spaced apart from each other in a left-right direction, and two elastic restoring members connected between said main frame unit and a corresponding one of said clamping arm units, said clamping arm units being driven to move relative to said main frame unit between a clamped position, in which said clamping arm units are moved close to each other for clamping therebetween the article carried by said main frame unit, and an open position, in which said clamping arm units are moved away from each other, said elastic restoring members constantly biasing said clamping arm units toward said clamped position;
- and
- a step mechanism pivotally disposed on said main frame unit and opposite to said clamping arm units in a front-rear direction, said step mechanism being configured to be stepped on and pressed down by a foot of a user to drive said clamping arm units to move toward said open position.
