Abstract
Abstract A modular belt link which includes a link base having at least one hinge barrel for connecting the link to adjacent links. A side guard is fixed to the link base, and defines a non-planar wall having a bottom and top joined by sides. The wall is twisted relative to an axis of rotation extending through said top and bottom.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
65 words
A modular belt link comprising: a link base having at least one hinge barrel for connecting the link to adjacent links, said link base having a direction of travel; a side guard fixed to said link base, and defining a non-planar wall having a bottom and top joined by sides, said wall being twisted relative an axis of rotation extending through said top and bottom.
Claim 2
Dependent Claim
65 words
A modular belt link comprising: a link base having at least one hinge barrel for connecting the link to adjacent links, said link base having a direction of travel; a side guard fixed to said link base, and defining a non-planar wall having a bottom and top joined by sides, said wall being twisted relative an axis of rotation extending through said top and bottom.
Claim 3
Dependent Claim
52 words
The modular belt link as in claim 1 , in which said bottom defines a first angle of rotation relative to said base direction of travel and said top defines a second angle of rotation relative to said base direction of travel, wherein said first and second angles of rotation are unequal.
Claim 4
Dependent Claim
24 words
The modular belt link as in claim 2 , in which said second angle of rotation is greater than said first angle of rotation.
Claim 5
Dependent Claim
29 words
The modular belt link as in claim 1 , in which said base includes a body, and said hinge barrel and said side guard are fixed to said body.
Claim 6
Dependent Claim
30 words
The modular belt link as in claim 4 , in which said body includes a planar top surface, and said axis of rotation is substantially perpendicular to said top surface.
Claim 7
Dependent Claim
18 words
The modular belt link as in claim 1 , in which said bottom is thicker than said top.
Claim 8
Dependent Claim
23 words
The modular belt link as in claim 1 , in which said base is formed as an integral part of said side guard.
Claim 9
Dependent Claim
96 words
A side guard for use on a conveyor belt, said side guard comprising: a non-planar wall defined by a top edge and bottom edge joined by side edges, and including an axis of rotation extending between said top edge and said bottom edge, wherein said non-planar wall is twisted relative to said axis of rotation, wherein a first vertical plane defined by said bottom edge passes through said axis of rotation, and a second vertical plane defined by said top edge passes through said axis of rotation, wherein said first and second planes are not coplanar.
Claim 10
Dependent Claim
96 words
A side guard for use on a conveyor belt, said side guard comprising: a non-planar wall defined by a top edge and bottom edge joined by side edges, and including an axis of rotation extending between said top edge and said bottom edge, wherein said non-planar wall is twisted relative to said axis of rotation, wherein a first vertical plane defined by said bottom edge passes through said axis of rotation, and a second vertical plane defined by said top edge passes through said axis of rotation, wherein said first and second planes are not coplanar.
Claim 11
Dependent Claim
17 words
The side guard as in claim 8 , including a link based fixed to said bottom edge.
Claim 12
Dependent Claim
22 words
The side guard as in claim 9 , in which said base is formed as an integral part of the side guard.
Claim 13
Dependent Claim
19 words
The side guard as in claim 8 , in which said bottom edge is thicker than said top edge.
Claim 14
Dependent Claim
82 words
A belt link comprising: a link base having at least one hinge barrel for connecting the link to adjacent links, said link base having a direction of travel; a side guard fixed to said link base, and including a non-planar wall defined by a top edge and bottom edge joined by side edges, said non-planar wall including an axis of rotation extending between said top edge and said bottom edge, wherein said non-planar wall is twisted relative to said axis of rotation.
Claim 15
Dependent Claim
82 words
A belt link comprising: a link base having at least one hinge barrel for connecting the link to adjacent links, said link base having a direction of travel; a side guard fixed to said link base, and including a non-planar wall defined by a top edge and bottom edge joined by side edges, said non-planar wall including an axis of rotation extending between said top edge and said bottom edge, wherein said non-planar wall is twisted relative to said axis of rotation.
Claim 16
Dependent Claim
50 words
The belt link as in claim 12 , in which a first vertical plane defined by said bottom edge passes through said axis of rotation, and a second vertical plane defined by said top edge passes through said axis of rotation, wherein said first and second planes are not coplanar.
Claim 17
Dependent Claim
22 words
The belt link as in claim 12 , in which said base is formed as an integral part of the side guard.
Claim 18
Dependent Claim
19 words
The belt link as in claim 12 , in which said bottom edge is thicker than said top edge.
