Abstract
A new concrete mixing device for mixing concrete as a user moves the device along a ground surface. The inventive device includes a rolling drum with one of the ends of the rolling drum having an opening into the interior of the rolling drum. The device also includes a handle member having opposite first and second ends and a pair of arms. The arms are spaced apart from each other at the first end of the handle member. Each of the arms has a mounting pin extending therefrom that face one another. The rolling drum is interposed between the arms with each of the ends of the rolling drum rotationally mounted to an associated mounting pin to permit free rotation of the rolling drum. A pair of hand grips are extended from the second end of the handle member.
Claims11
A device for mixing concrete, comprising:
- a rolling drum being generally cylindrical and having an interior, and a pair of opposite generally circular ends;
- one of said ends of said rolling drum having an opening into said interior of said rolling drum, the one end of said rolling drum having a closure for said opening of the one end of said rolling drum;
- a handle member having opposite first and second ends, and a pair of arms;
- said arms being spaced apart from each other at said first end of said handle member, each of said arms having a mounting pin extending therefrom, said mounting pins facing one another;
- said rolling drum being interposed between said arms, each of said ends of said rolling drum being rotationally mounted to an associated mounting pin to permit free rotation of said rolling drum;
- a pair of hand grips being extended from said second end of said handle member:
- and
- wherein said arms of said handle are pivotally coupled together at a pivot point between said first and second ends of said handle member, one of said arms having one of said hand grips, another of said arms having another of said hand grips.

A device for mixing concrete, comprising:
- a rolling drum being generally cylindrical and having an interior, and a pair of opposite generally circular ends;
- said interior of said rolling drum having a pair of elongate mixing blades therein, one of said mixing blades being extended from one of said ends of said rolling drum towards the other of said ends of said rolling drum, another of said mixing blades being extended from the other of said ends of said rolling drum towards the one of said ends of said rolling drum;
- one of said ends of said rolling drum having an opening into said interior of said rolling drum, the one end of said rolling drum having a closure for said opening of the one end of said rolling drum, said closure being threadably attached to said rolling drum;
- a handle member having opposite first and second ends, and a pair of arms;
- said arms being spaced apart from each other at said first end of said handle member, each of said arms having a mounting pin extending therefrom, said mounting pins facing one another;
- said rolling drum being interposed between said arms, each of said ends of said rolling drum being rotationally mounted to an associated mounting pin to permit free rotation of said rolling drum, one of said ends of said rolling drum being rotationally mounted to one of said mounting pins, another of said ends of said rolling drum being rotationally mounted to the other of said mounting pins;
- a pair of hand grips being extended in opposite directions from said second end of said handle member;
- said arms of said handle being pivotally coupled together at a pivot point between said first and second ends of said handle member, one of said arms having one of said hand grips, another of said arms having another of said hand grips;
- a locking assembly for holding said arms together such that the lengths of said arms are generally parallel with each other, said locking assembly comprising a latch pin and a pair of bores, one of said bores being extended through a first of said arms, the other of said bores being extended into a second of said arms, said bores being coaxial when the lengths of said arms are generally parallel, said latch pin being coupled to said first of said arms, said latch pin being insertable into said bores when said bores are coaxial;
- said hand grips being coaxial when the lengths of the arms are generally parallel, said hand grips lying in a common plane;
- a measuring cup being detachably attached to said handle member, said measuring cup having a slot, one of said arms having a mounting bracket, said slot receiving said mounting bracket to detachably attach said measuring cup to said arm.
