Abstract

A device for picking up animal waste is described that use a waste bag. The pick-up device includes a first concave body and a second concave body that form a waste collection cavity. A hinge along a fixed edge allows a movable edge to move between an open position and a closed position. A spring biases the device into the closed position. An activation mechanism is provided to overcome the biasing force of the spring. Waste bag retainers retainer the waste bag within the waste collection cavity.

Claims

1. Device for picking up animal waste, comprising in combination:

a waste bag, comprising;

a plastic body having an open top, enclosed sides and a bottom;

at least one attachment strip depending from and positioned along the bottom of the plastic body, the at least one attachment strip having post receiving openings for mounting the waste bag to a pick-up device; and

a pick-up device, comprising;

a first concave body and a second concave body, each of the first concave body and the second concave body having an exterior surface and an interior surface, the interior surface of the first concave body and the interior surface of the second concave body collectively forming a waste collection cavity, each of the first concave body and the second concave body having a fixed edge and a movable edge opposed to the fixed edge;

a hinge along the fixed edge of the first concave body and the second concave body forming a pivot axis allowing relative movement of the first concave body and the second concave between an open position and a closed position, in the open position the movable edge of the first concave body is spaced from the movable edge of the second concave body to permit access to the waste collection cavity;

a spring biasing the first concave body and the second concave body into the closed position;

an activation mechanism for overcoming the biasing force of the spring to move the first concave body and the second concave body to the open position; and

at least one waste bag retainer comprised of posts positioned on the exterior surface in spaced relation on one of the first concave body or the second concave body adjacent to the hinge, the waste bag being positioned within the waste collection cavity with the posts of the waste bag retainer engaging the post receiving openings on the attachment strip along the bottom of the waste bag and the open top of the waste bag being folded back over the exterior surface of the first concave body and the second concave body.

2. The device of claim 1, wherein the activation mechanism is a first handle on the first concave body and a second handle on the second concave body, such that a manual force applied concurrently to the first handle and the second handle overcomes the biasing force of the spring.

3. The device of claim 2, wherein the first handle and the second handle have concave sides to engage and capture side ear handles on a waste bag.

4. Device for picking up animal waste, comprising in combination:

a waste bag, comprising;

a plastic body having an open top, enclosed sides and a bottom;

a pick-up device, comprising;

a first concave body and a second concave body, each of the first concave body and the second concave body having an exterior surface and an interior surface, the interior surface of the first concave body and the interior surface of the second concave body collectively forming a waste collection cavity, each of the first concave body and the second concave body having a fixed edge and a movable edge opposed to the fixed edge;

a hinge along the fixed edge of the first concave body and the second concave body forming a pivot axis allowing relative movement of the first concave body and the second concave between an open position and a closed position, in the open position the movable edge of the first concave body is spaced from the movable edge of the second concave body to permit access to the waste collection cavity;

a spring biasing the first concave body and the second concave body into the closed position;

an activation mechanism for overcoming the biasing force of the spring to move the first concave body and the second concave body to the open position; and

at least one waste bag retainer on one of the first concave body or the second concave body adjacent to the hinge, the waste bag being positioned within the waste collection cavity with the waste bag retainer engaging the bottom of the waste bag and the open top of the waste bag being folded back over the exterior surface of the first concave body and the second concave body; and

a locking mechanism to lock the first concave body and the second concave body into the open position.
