Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
45 words
A toothed belt with teeth blocks consisting of elastic material, an armor cord and conveying and transporting means having supporting elements engaging selected tooth blacks and cover plates which are twice the width of a tooth block and which embracingly engage two adjacent tooth blocks.
Claim 2
Dependent Claim
45 words
A toothed belt with teeth blocks consisting of elastic material, an armor cord and conveying and transporting means having supporting elements engaging selected tooth blacks and cover plates which are twice the width of a tooth block and which embracingly engage two adjacent tooth blocks.
Claim 3
Dependent Claim
73 words
A toothed belt according to claim 1, wherein the supporting element of double width is additionally secured in a tooth block in a conventional manner by cross bars introduced into traverse bore holes, while said element embraces the adjacent tooth block by means of its cross pieces with the cross piece - located on the bottom side of the tooth block - together with the cover plates of the supporting element forming bracket.
Claim 4
Dependent Claim
61 words
A toothed belt with teeth blocks consisting of elastic material, an armor cord and conveying and transporting means having supporting elements engaging selected tooth blocks, each supporting element comprising two members and a hinge flexibly joining said members with its axis of rotation located in a tooth gap between two adjacent teeth blocks in the neutral zone of the toothed belt.
Claim 5
Dependent Claim
61 words
A toothed belt with teeth blocks consisting of elastic material, an armor cord and conveying and transporting means having supporting elements engaging selected tooth blocks, each supporting element comprising two members and a hinge flexibly joining said members with its axis of rotation located in a tooth gap between two adjacent teeth blocks in the neutral zone of the toothed belt.
Claim 6
Dependent Claim
81 words
A toothed belt with teeth blocks consisting of elastic material, an armor cord and conveying and transporting means having supporting elements engaging selected tooth blocks, each supporting element comprising a central member and two outer members and hinges interconnecting said members, said central member being a cover plate, said outer members being attached to said selected tooth blocks, said hinges having an axis of rotation extending in tooth gaps between the tooth blocks in the neutral zone of the toothed belt.
Claim 7
Dependent Claim
81 words
A toothed belt with teeth blocks consisting of elastic material, an armor cord and conveying and transporting means having supporting elements engaging selected tooth blocks, each supporting element comprising a central member and two outer members and hinges interconnecting said members, said central member being a cover plate, said outer members being attached to said selected tooth blocks, said hinges having an axis of rotation extending in tooth gaps between the tooth blocks in the neutral zone of the toothed belt.
