Abstract

A conveyor belt module ( 20 ) includes a movable hinge rod retainer ( 220 ) that can be opened and closed without tools. The movable hinge rod retainer facilitates opening and rejoining of the conveyor belt ( 100 ) at one or more dedicated locations. In a first position, the hinge rod retainer locks a hinge rod ( 130 ) withing a hinge rod passageway. A user can easily move the hinge rod retainer to a second position in which the hinge rod passageway is open to allow removal of the hinge rod.

First claim

What is claimed is:

1. A conveyor belt module comprising:
a body extending in thickness from a top conveying surface to an opposite bottom surface, laterally from a first edge to a second edge and longitudinally from a first end to a second end, the body including a first set of hinge elements spaced apart along the first end and defining a first rod passageway, a second set of hinge elements spaced along the second end and defining a second rod passageway and a recess in the body between the top conveying surface and the opposite bottom surface, the recess intersecting the first rod passageway; and
a pivotable hinge rod retainer for a hinge rod seated in the recess and mounted on a hinge rod extending through the second rod passageway, wherein the pivotable hinge rod retainer pivots between a closed position blocking the first rod passageway and an open position in which the first rod passageway is open.

2. The conveyor belt module of claim 1 , wherein the pivotable hinge rod retainer further comprises a body that splits to form two arms including keyhole-shaped openings for snapping onto the hinge rod.

3. The conveyor belt module of claim 1 , wherein the pivotable rod retainer further comprises a latching tab and the recess includes an opening for receiving the latching tab via a snap-fit connection.

4. The conveyor belt module of claim 1 , wherein the module body and the pivotable rod retainer include magnets forming a latch.

5. The conveyor belt module of claim 1 , wherein the pivotable hinge rod retainer includes a base with an opening for receiving the second hinge rod, a head including a rod recess closed by a wall for blocking the first rod passageway and a neck connecting the head and the base.

6. The conveyor belt module of claim 5 , wherein the recess in the body includes side walls, a substantially horizontal surface for abutting a bottom surface of the neck, a sloped surface for abutting a rear surface of the head and a flat bottom surface extending to the first edge of the module body.
