Abstract

A modular conveyor belt constructed of a series of articulating rows of belt modules having flights formed atop laterally consecutive interleaved hinge elements of adjacent belt rows. The flights on leading and trailing rows are aligned when the belt is running flat, but open up for cleaning as their rows articulate about a sprocket.

First claim

What is claimed is:

1. A modular conveyor belt comprising:
a series of rows of one or more belt modules, each row extending in a direction of belt travel from a trailing end to a leading end and laterally from a left side to a right side and having a top side, wherein each row has one or more hinge elements at the trailing end and one or more hinge elements at the leading end, wherein the one or more hinge elements at the trailing end of a row are interleaved and hingedly joined with the one or more hinge elements at the leading end of an adjacent row;
wherein at least some of the adjacent rows have flights extending upward from laterally consecutive interleaved hinge elements; and
wherein the lateral dimension of each flight is greater than the dimension of the flight in the direction of belt travel.

2. A modular conveyor belt as in claim 1 wherein the flights on adjacent rows are in alignment when the adjacent rows are running flat and wherein the flights on adjacent rows are out of alignment when the adjacent rows are articulating.

3. A modular conveyor belt as in claim 1 wherein each flight extends upward from an individual hinge element.

4. A modular conveyor belt as in claim 1 wherein the lateral dimension of each flight equals the lateral dimension of the hinge element from which the flight extends.

5. A modular conveyor belt as in claim 1 wherein the one or more hinge elements at the leading end of each row are laterally offset from the one or more hinge elements at the trailing end of each row.

6. A conveyor belt module comprising:
an intermediate portion extending in a direction of travel from a first end to a second end and laterally in width and having a top side;
one or more first hinge elements extending outward from a portion of the first end of the intermediate portion and defining one or more spaces at the first end laterally adjacent to the one or more first hinge elements;
one or more second hinge elements extending outward from a portion of the second end of the intermediate portion and defining one or more spaces at the second end laterally adjacent to the one or more second hinge elements, wherein the first hinge elements are laterally offset from the second hinge elements;
one or more flights extending upward from the one or more first hinge elements;
wherein each flight extends upward from an individual first hinge element without spanning any of the spaces along the first end; and
wherein the lateral dimension of each flight is greater than the dimension of the flight in the direction of belt travel.

7. A conveyor belt module as in claim 6 wherein the lateral dimension of each flight equals the lateral dimension of the hinge element from which the flight extends.

8. A conveyor belt module as in claim 6 wherein each flight is a plate perpendicular to the plane of the conveyor belt module.

9. A conveyor belt module comprising:
an intermediate portion extending in a direction of travel from a first end to a second end and laterally in width and having a top side;
a plurality of first hinge elements laterally spaced apart along the first end;
a plurality of second hinge elements laterally spaced apart along the second end, wherein the first hinge elements are laterally offset from the second hinge elements;
a plurality of flights extending upward from the plurality of first hinge elements;
wherein the lateral dimension of each flight is greater than the dimension of the flight in the direction of travel.

10. A modular conveyor belt as in claim 9 wherein each flight extends upward from an individual hinge element.

11. A modular conveyor belt as in claim 10 wherein the lateral dimension of each flight equals the lateral dimension of the hinge element from which the flight extends.

12. A conveyor belt as in claim 9 wherein each flight is a plate perpendicular to the plane of the conveyor belt module.
