Abstract

A trolley configured for use to carry both round and rectangular folding tables of a variety of sizes. The trolley includes a frame having a floor located adjacent a loading end of the frame. The floor includes a planar central portion bounded on each side by angled ramp portions which terminate at elevated flat portions, one of the elevated flat portions being located adjacent the loading end of the frame; and a plurality of receivers located on the frame. The trolley also includes a handle rack locatable at an end of the frame opposite the loading end of the frame. The handle rack includes a pair of rack legs, each rack leg having a handle rack mount located at a lower end of the rack leg and configured to be received by one of the receivers of the frame. The handle rack mounts cooperate with corresponding ones of the receivers of the frame to enable the handle rack to be mounted to the frame and selectively positioned in either an upright position relative to the frame or in a folded orientation wherein the handle rack is folded to a lowered position adjacent the frame. The trolley also includes a pair of side rails locatable adjacent sides of the frame, the side rails including a pair of rail legs. Each rail leg has a rail mount located at a lower end of the rail leg and configured to be received by one of the receivers of the frame. The rail mounts cooperate with corresponding ones of the receivers of the frame to enable the side rails to be mounted to the frame and selectively positioned in either an upright position relative to the frame or in a folded orientation wherein the side rails are each folded to a lowered position adjacent the frame.

First claim

The invention claimed is:

1. A trolley configured for use to carry both round and rectangular folding tables of a variety of sizes, the trolley comprising:
a frame having side edges and a floor located adjacent a loading end of the frame and extending substantially between the side edges of the frame, the floor defined by a planar central portion bounded on each side by angled ramp portions which terminate at elevated flat portions, one of the elevated flat portions being located adjacent the loading end of the frame;
a plurality of receivers located on the frame;
a handle rack locatable at an end of the frame opposite the loading end of the frame, the rack including a pair of rack legs, each rack leg having a handle rack mount located at a lower end of the rack leg and configured to be received by one of the receivers of the frame, wherein the handle rack mounts cooperate with corresponding ones of the receivers of the frame to enable the handle rack to be mounted to the frame and selectively positioned in either an upright position relative to the frame or in a folded orientation wherein the handle rack is folded to a lowered position adjacent the frame; and
a pair of side rails locatable adjacent sides of the frame, the side rails including a pair of rail legs, each rail leg having a rail mount located at a lower end of the rail leg and configured to be received by one of the receivers of the frame, wherein the rail mounts cooperate with corresponding ones of the receivers of the frame to enable the side rails to be mounted to the frame and selectively positioned in either an upright position relative to the frame or in a folded orientation wherein the side rails are each folded to a lowered position adjacent the frame.

2. The trolley of claim 1 , further comprising a load support removably positionable to span between the side rails.

3. The trolley of claim 1 , further comprising a gate pivotally mounted adjacent to the loading end of the trolley.

4. The trolley of claim 3 , further comprising a gate adjuster operably associated with the gate and one of the side rails to adjustably position the gate at a desired angle relative to the frame.

5. The trolley of claim 3 , further comprising a locking hinge operably associated with the gate to adjustably position the gate at a desired angle relative to the frame.

6. The trolley of claim 1 , wherein the frame includes floor supports and the floor comprises two pairs of angled steel plates, each pair having one plate overlying the other, with the overlying plate including a lip that overlies one of the floor supports.

7. A trolley configured for use to carry both round and rectangular folding tables of a variety of sizes, the trolley comprising:
a frame having floor supports and a floor located adjacent a loading end of the frame, the floor comprising two pairs of angled steel plates, each pair of angled plates having one plate overlying the other, with the overlying plate including a lip that overlies one of the floor supports;
a plurality of receivers located on the frame;
a handle rack locatable at an end of the frame opposite the loading end of the frame, the rack including a pair of rack legs, each rack leg having a handle rack mount located at a lower end of the rack leg and configured to be received by one of the receivers of the frame, wherein the handle rack mounts cooperate with corresponding ones of the receivers of the frame to enable the handle rack to be mounted to the frame and selectively positioned in either an upright position relative to the frame or in a folded orientation wherein the handle rack is folded to a lowered position adjacent the frame; and
a pair of side rails locatable adjacent sides of the frame, the side rails including a pair of rail legs, each rail leg having a rail mount located at a lower end of the rail leg and configured to be received by one of the receivers of the frame, wherein the rail mounts cooperate with corresponding ones of the receivers of the frame to enable the side rails to be mounted to the frame and selectively positioned in either an upright position relative to the frame or in a folded orientation wherein the side rails are each folded to a lowered position adjacent the frame.
