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; 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 a floor located adjacent a loading end 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, and floor supports, wherein the floor comprises two pairs of angled plates, each pair 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.

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

3. The trolley of claim 2 , wherein the load support comprises a wire receivable onto receivers located on the side rails.

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

5. The trolley of claim 4 , 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.

6. The trolley of claim 1 , wherein the receivers on the frame comprise upright cylinders having a plurality of longitudinal open slots and closed slots formed in their sidewall, and the mounts of the side rails and the handle rack comprise pegs that cooperate with the open slots and the closed slots to permit folding of the side rails and the handle rack.

7. The trolley of claim 6 , wherein the receivers comprise square cylinders.

8. A trolley configured for use to carry both round and rectangular folding tables of a variety of sizes, the trolley comprising:
a frame having a floor located adjacent a loading end of the frame, the floor including a planar central portion bounded on each side by angled ramp portions which terminate at elevated flat portions;
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;
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; and
a load support removably positionable to span between the side rails, comprising a wire receivable onto receivers located on the side rails.

9. A trolley configured for use to carry both round and rectangular folding tables of a variety of sizes, the trolley comprising:
a frame having a floor located adjacent a loading end of the frame, the floor including a planar central portion bounded on each side by angled ramp portions which terminate at elevated flat portions;
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;
wherein the receivers comprising upright cylinders having a plurality of longitudinal open slots and closed slots formed in their sidewall, and the mounts of the side rails and the handle rack comprising pegs that cooperate with the open slots and the closed slots to permit folding of the side rails and the handle rack.
