Abstract
Abstract An endless conveyor belt formed of plastic belt modules and capable of following a curved path. The modules include first and second module surfaces, i.e., a top, product-conveying surface and a bottom, sprocket-driven surface. An intermediate section extends across the width of each module transverse to the direction of belt travel. A plurality of snap-on side guards are mounted in vertical openings disposed in the belt modules. Each side guard includes a central post having opposed wings extending in a forwardly and a rearwardly direction along the direction of conveyor belt travel. The wings are staggered in the lateral direction so that the forward wing of a first side guard overlaps with the rearward wing of an immediately adjacent second side guard.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
152 words
A modular belt system, comprising: a plurality of belt modules having a product conveying surface, a bottom surface disposed opposite from the product conveying surface and an opening disposed substantially perpendicular to the product conveying surface, the opening extending from the product conveying surface to the bottom surface, the opening being defined by a first inner wall that is substantially straight and a second inner wall having a straight portion extending from the product conveying surface to a point between the product conveying surface and the bottom surface, the second inner wall having a recessed portion forming a ledge, the opening having a larger diameter at the bottom surface than at the product conveying surface; and a side guard having a central post with a projection disposed thereon, the central post capable of sliding substantially perpendicular into the opening such that the projection engages with the recessed portion in the belt module.
Claim 2
Dependent Claim
152 words
A modular belt system, comprising: a plurality of belt modules having a product conveying surface, a bottom surface disposed opposite from the product conveying surface and an opening disposed substantially perpendicular to the product conveying surface, the opening extending from the product conveying surface to the bottom surface, the opening being defined by a first inner wall that is substantially straight and a second inner wall having a straight portion extending from the product conveying surface to a point between the product conveying surface and the bottom surface, the second inner wall having a recessed portion forming a ledge, the opening having a larger diameter at the bottom surface than at the product conveying surface; and a side guard having a central post with a projection disposed thereon, the central post capable of sliding substantially perpendicular into the opening such that the projection engages with the recessed portion in the belt module.
Claim 3
Dependent Claim
101 words
A modular belt system, comprising: a plurality of belt modules having a product conveying surface and an opening disposed substantially perpendicular to the product conveying surface, the module having a recessed portion defined therein adjacent to the opening such that a ledge is formed adjacent to the opening; and a side guard having a central post with a projection disposed theteon, the central post capable of sliding into the opening such that the projection engages with the recessed portion in the belt module wherein the central post has a back wall that is beveled inward and disposed opposite from the projection.
Claim 4
Dependent Claim
101 words
A modular belt system, comprising: a plurality of belt modules having a product conveying surface and an opening disposed substantially perpendicular to the product conveying surface, the module having a recessed portion defined therein adjacent to the opening such that a ledge is formed adjacent to the opening; and a side guard having a central post with a projection disposed theteon, the central post capable of sliding into the opening such that the projection engages with the recessed portion in the belt module wherein the central post has a back wall that is beveled inward and disposed opposite from the projection.
Claim 5
Dependent Claim
75 words
The modular belt system of claim 2 , wherein the plurality of belt modules comprises an intermediate section having a sinusoidal shape and a plurality of link ends extending from the intermediate section in opposite directions such that one of the plurality of belt modules is capable of being intercalated with an adjacent belt module by a pivot rod, the adjacent belt modules forming a radius belt capable of collapsing around a curved conveying path.
Claim 6
Dependent Claim
25 words
The modular belt system of claim 2 , wherein the side guard has a first wing extending from the central post in a first direction.
Claim 7
Dependent Claim
29 words
The modular belt system of claim 4 , wherein the side guard has a second wing extending from the central post in a second direction opposite the first direction.
Claim 8
Dependent Claim
33 words
The modular belt system of claim 5 , wherein the first wing and the second wing are offset laterally with respect to a longitudinal axis defined through the center of the central post.
Claim 9
Dependent Claim
22 words
The modular belt system of claim 2 , wherein a front surface of the central post is coplanar with the second wing.
