Abstract
Abstract A self-supporting articulated chain composed of identical links pivoted to one another, each link terminating at its opposite ends on one side of its longitudinal center plane in parallel abutment edges and on the other side of such plane in obliquely disposed abutment edges, alternate ones of the links having cover members of such length as to project beyond both ends of its associated link to provide a cover for the gap which exists between adjacent links. One end of each link is displaced laterally by an amount corresponding to its wall thickness and the longitudinal edges of each link are bent to form edges of double wall thickness.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
123 words
A self-supporting articulated chain composed of a plurality of identical links; means pivotally connecting said links to one another, each of said links having a body member terminating at its opposite ends on one side of a longitudinal center plane running through the pivot axes in first abutment edges substantially parallel to each other and on the other side of said plane in second abutment edges extending obliquely to each other, one end of said body member being displaced to one side thereof by an amount corresponding to the thickness of said body member; and a cover member at one side of alternate ones of said links and extending beyond both ends of the latter to cover the pivotal connection between adjacent links.
Claim 2
Dependent Claim
123 words
A self-supporting articulated chain composed of a plurality of identical links; means pivotally connecting said links to one another, each of said links having a body member terminating at its opposite ends on one side of a longitudinal center plane running through the pivot axes in first abutment edges substantially parallel to each other and on the other side of said plane in second abutment edges extending obliquely to each other, one end of said body member being displaced to one side thereof by an amount corresponding to the thickness of said body member; and a cover member at one side of alternate ones of said links and extending beyond both ends of the latter to cover the pivotal connection between adjacent links.
Claim 3
Dependent Claim
22 words
A chain according to claim 1 wherein each of said cover members is mounted alongside its associated link by said pivotal means.
Claim 4
Dependent Claim
52 words
A chain according to claim 1 including a further cover member at the opposite side of said alternate links and having a length corresponding substantially to the length of the first mentioned cover member, the opposite ends of said further cover member being apertured and accommodating the displaced ends of successive links.
Claim 5
Dependent Claim
33 words
A chain according to claim 3 wherein the ends of said further cover member are displaced tranversely an amount corresponding to the displacement of said one end of each of said body members.
Claim 6
Dependent Claim
30 words
A chain according to claim 3 wherein at least one end of said further member includes means for enabling dirt or the like to pass through said further cover member.
Claim 7
Dependent Claim
21 words
A chain according to claim 1 wherein the longitudinal edges of each of said links are bent to double wall thickness.
Claim 8
Dependent Claim
18 words
A chain according to claim 1 wherein the ends of said cover member are formed on circular arcs.
Claim 9
Dependent Claim
18 words
A chain according to claim 1 wherein the second abutment edges diverge in a direction toward said plane.
