Abstract
Abstract A belt-like conveyor including at least two continuous chains which are parallel to one another and driven by sprocket wheels. The chains have a number of overlapping chain links and a number of carrying bars which are disposed transversely to the chains to which the end pieces of the bars are also connected. The end pieces of the bars also function as pins for the chain links while penetrating two of the latter and the remaining part of the carrying bars between the two end pieces serve as a carrying area of the conveyor. The carrying bars extend over the top of the chain links toward the exterior and end portions of the carrying bars are U-like bent toward the bottom and toward the inside and penetrate the chain links from the exterior, which permits an unimpeded lateral sliding on and off of pieces and which provides an enlarged carrying area and which is also suited for conveying heavy pieces while developng only a low surface pressure.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
148 words
Conveyor comprising: at least two parallel, continuous chains which are driven by sprocket wheels and each having a number of overlapping chain links; a number of carrying bars which have end portions and which are disposed transversely to the chains and are connected thereto approximately at their ends, end portions of these carrying bars serving as pins for the chain links, two of which each end portion penetrates and the remaining part of each carrying bar which is between the end portions serving as the carrying zone of the conveyor; at both longitudinal sides of the conveyor -- with respect to the top, conveying side of the conveyor -- the carrying bars extending over the top of the chain links toward the exterior and end portions of the carrying bars being U-like bent toward the bottom and toward the inside and penetrating the chain links from the exterior.
Claim 2
Dependent Claim
148 words
Conveyor comprising: at least two parallel, continuous chains which are driven by sprocket wheels and each having a number of overlapping chain links; a number of carrying bars which have end portions and which are disposed transversely to the chains and are connected thereto approximately at their ends, end portions of these carrying bars serving as pins for the chain links, two of which each end portion penetrates and the remaining part of each carrying bar which is between the end portions serving as the carrying zone of the conveyor; at both longitudinal sides of the conveyor -- with respect to the top, conveying side of the conveyor -- the carrying bars extending over the top of the chain links toward the exterior and end portions of the carrying bars being U-like bent toward the bottom and toward the inside and penetrating the chain links from the exterior.
Claim 3
Dependent Claim
46 words
Conveyor in accordance with claim 1, in which the chain links are formed as one piece each from V-like bent strips having sides which diverge and having a front pair and a rear pair of aligning pin openings for the end portions of the carrying bars.
Claim 4
Dependent Claim
50 words
Conveyor in accordance with claim 1, in which the chain links are configured as one piece each from U-like bent strips having sides which increasingly diverge, and each chain link having a front pair and a rear pair of aligning pin openings for the end portions of the carrying bars.
Claim 5
Dependent Claim
33 words
Conveyor in accordance with claim 1, in which each chain link has one pair of openings which is configured as a pair of long holes extending in a moving direction of the conveyor.
Claim 6
Dependent Claim
29 words
Conveyor in accordance with claim 1 in which approximately at its end, each carrying bar is rigidly connected to one of the chain links which each carrying bar penetrates.
Claim 7
Dependent Claim
51 words
Conveyor in accordance with claim 1, in which the carrying bars have bottom sides and the carrying bars are inclined to one common direction and at the edge of the carrying zone, and in the area of the chain links, the carrying bars rest with their bottom sides on the latter.
Claim 8
Dependent Claim
31 words
Conveyor in accordance with claim 1, which comprises at least one wire spiral which is slid on at least one of the carrying bars in the area of the carrying zone.
Claim 9
Dependent Claim
87 words
Conveyor in accordance with claim 1, in which the bent end portions of the carrying bars which penetrate the chain links and form the exterior, and in which toward the interior the carrying bars extend over the chain links toward the interior under the carrying zone, and in which on each longitudinal side of the conveyor, the carrying bars glide in a guiding groove which is open toward the exterior and is part of a support and guiding frame extending underneath the carrying zone of the conveyor.
Claim 10
Dependent Claim
25 words
Conveyor in accordance with claim 1, in which the chain links and the carrying bars are made of plastic and have a glass fiber reinforcement.
Claim 11
Dependent Claim
