Abstract: A chain with mutually connected chain links (1, 2) each comprising a back portion and two parallel wall portions protruding substantially perpendicularly therefrom, in which wall portions corresponding rivet holes have been provided in each of the two and members of the chain link, wherein the chain links (1, 2) are connected with one another by means of an end member of a chain link with a comparatively narrow (2) back portion which is inserted into an end member of a neighbouring chain link with a comparatively broad back portion (1) such that the rivet holes (1c, 2c) in the parallel wall portions of the two end members (1a, 1b,2a-2b) are positioned opposite one another for engaging a river (3) or a shaft member. By use of rivets or shaft members of such a length that the rivet (3) may be axially retained by deformation of areas of said wall portions (1a-1b) around the rivet holes (1c) from the exterior side for reducing the clear opening of the rivet holes, a chain is produced by use of less material and at subsequently reduced costs relative to chains hitherto known.

Abstract translation: 一种具有相互连接的链节（1,2）的链，每个链条包括后部和与其大致垂直地突出的两个平行的壁部分，其中在链节的两个和部件中的每一个中已经提供了相应的铆钉孔的壁部分，其中 链节（1,2）通过具有较窄（2）后部的链节的端部构件彼此连接，该后部插入相邻链节的端部构件中，具有较宽的后部 （1），使得两个端部构件（1a，1b，2a-2b）的平行壁部分中的铆钉孔（1c，2c）彼此相对定位，用于接合河流（3）或轴构件。 通过使用这样一段长度的铆钉或轴构件，铆钉（3）可以通过从外侧围绕铆钉孔（1c）的所述壁部分（1a-1b）的区域的变形而被轴向保持，以减少透明开口 的铆钉孔，通过使用较少的材料制造链条，并且相对于迄今为止已知的链条，随后降低成本。
