Abstract

A staging cart for moving multiple packaged mattresses generally includes a base frame having a length and a width dimension; a handle frame extending upwardly from a rear end of the cart; a pair of rear wheels and a pair of forward wheels mounted to a bottom surface of the base frame at the rear and forward ends of the base frame, respectively; a platform portion coupled to the base frame spanning a length of the base frame and having a planar surface, wherein the platform portion has a width dimension less than the width dimension of the base frame and is medially located within the base frame; and at least one roller coupled to the base frame spanning the length dimension and adjacent to at least one side of the platform portion, wherein the at least one roller has an axis of rotation parallel to the longitudinal axis of the platform portion.

First claim

What is claimed is:

1. A cart for transporting packaged mattresses, the cart comprising:
a base frame having a length and a width dimension;
a handle frame extending upwardly from a rear end of the cart;
a pair of rear wheels and a pair of forward wheels mounted to a bottom surface of the base frame at the rear and forward ends of the base frame, respectively;
a platform portion free of rollers coupled to the base frame spanning a length of the base frame and having a planar surface, wherein the platform portion has a width dimension less than the width dimension of the base frame and is medially located within the base frame; and
at least one roller coupled to the base frame spanning the length dimension and adjacent to at least one side of the platform portion, wherein the at least one roller has an axis of rotation parallel to the longitudinal axis of the platform portion, and wherein the at least one roller spans only a portion of the width dimension.

2. The cart of claim 1 , wherein the rear and forward wheels are caster wheels.

3. The cart of claim 1 , wherein the platform portion comprises a plastic contact surface.

4. The cart of claim 1 , wherein the at least one roller on at least one side of the platform portion comprises two or more rows.

5. The cart of claim 1 , wherein the at least one roller is adjacent to each side of the platform portion and comprises two or more rows.

6. The cart of claim 1 , wherein the at least one roller coupled to the base frame spanning the length dimension comprises multiple rollers disposed within a row.

7. The cart of claim 1 , wherein a top surface of the at least one roller is slightly raised relative to the planar contact surface of the platform portion.

8. The cart of claim 1 , wherein a top surface of the at least one roller is coplanar to the planar contact surface of the platform portion.
