Embodiment Construction

[0014] In the illustrated embodiment, the open chain consists of vertical links 2 , 2 ′ designed as flat links and a horizontal link 3 always connecting the two vertical links 2 , 2 ′ to each other. figure 1 The subsequence of the open strand 1 strand is shown. This subsequence includes a first link, which is vertical link 2 in the illustrated embodiment. The inner length of the chain link 2 is divided into two movable chambers which are spaced apart from each other by a projection 8 , 9 protruding from the side 6 , 7 connecting the two arcuate segments 4 , 5 to each other. The projections 8 , 9 are designed as slopes facing the arc section 4 or 5 , the slopes can also be curved here, and rest against the curved surface of the second link 3 in a suitable concave manner. The distance between the two mutually facing surfaces of the projections 8 , 9 is for this purpose smaller than the diameter of the horizontal link 3 . The second link behind the first link 2 , namely the hor...

Abstract

The present invention relates to an opening chain having a series of chain loops clasping each other, the chain loop sequence is composed of repeating sub-sequence chain loop, in each sub-sequence, a first chain loop is separated provided having a dividing element projecting from side internal side to inside, reducing the inner radii in transverse direction and dividing the internal chamber of the chain loop into two active chambers at least on one of its two straight edge, when the chain is loose, the second chain loop in the first chain loop is hitched, restrained by effective width of at least a dividing element and external shape, diameter and/or other active chamber internal length of the second chain loop inserting the first chain loop, only the part intruding into the first chain loop active chamber is achieved, that is when a longitudinal axis of the second chain loop is moved from an intended, substantially aligned position by less than 90 degrees, an outside of an arc portions of the second chain loop that engages a movement space of the first chain loop contacts the dividing element, and an inside of a shank portion of the second chain loop contacts an arc portion of the first chain loop.

Description

technical field [0001] The invention relates to an open chain, which is composed of a series of chain links which are successively hooked to each other. Background technique [0002] An open chain consists of many links that are hooked to each other. In the case of open chains for industrial use, for example as elevator chains or in mining, for example in underground coal mining, the individual chain links are subjected to high tensile loads. An open chain has its maximum tensile load capacity when the links are arranged one behind the other and the two facing arcs of every two consecutive links abut each other with their inner sides. The rated load capacity of an open chain generally presupposes that the links of the open chain under tensile stress are arranged relative to each other in the manner described above. However, if each chain link is not in its prescribed arrangement position, for example, the second chain link hung in the first chain link is not connected with...
