Embodiment Construction

[0019] figure 1 A side view is shown of a chain joint 1 having a main body 2 designed substantially in the form of an oval link, the main body 2 comprising two longitudinal arms 3, 4 parallel to each other, each longitudinal arm via Bent loops 5 , 6 are connected to each other at their ends, wherein in the illustrated embodiment they are shown in side view forming a semicircle.

[0020] in one of the two longitudinal arms, i.e. in figure 1 Longitudinal arm 4 indicated at the top, a receiving opening 7 is formed in the middle which, when open, allows the oval link to be hooked to the inner opening 8 surrounded by the chain joint 1 or its body 2 .

[0021] as from figure 1 and especially from Figure 4 It can be seen from the Figure 4 show figure 1 The three-dimensional diagonal representation of the main body 2 of the chain joint 1, the receiving opening 7 is attached to the middle part on the longitudinal arm 4 and is bounded by the longitudinal arm parts 4A and 4B respe...

Abstract

In a chain joint (1) for link chains, having a main body (2) in the form of an oval chain link with two mutually parallel longitudinal legs (3, 4) which are connected to one another at their ends in each case via a rounded link portion (5, 6) and one of which has an interruption for forming a receiving opening (7) for the hooking-in of oval chain links into an internal opening (8) of the main body (2), said receiving opening being bounded at its ends by in each case one longitudinal leg section (4A, 4B), wherein, in said longitudinal leg (4), there is provided a threaded bore (9) which runs in the longitudinal direction of said longitudinal leg and which extends in both longitudinal leg sections (4A, 4B) and into which there can be screwed a closure screw (10) which, in the screwed-in state, engages with the threaded bore (9) in both longitudinal leg sections (4A, 4B), it is provided that, while maintaining the predefined sizes for outer circumference (A) and link width (B) of the main body (2), said main body is provided, in the region of its longitudinal legs (3, 4), with a profile cross section (Q1) that is larger than the profile cross section (Q2) in the region of its rounded link portions (5, 6).

Description

technical field [0001] The invention relates to a chain joint for a chain link having a body in the form of an oval link with two longitudinal arms parallel to each other and each at its end via a curved loop connected together, wherein one of the longitudinal arms has a break, which is used to form a receiving opening for hooking the oval link into the internal opening of the main body, the receiving opening being defined by each longitudinal arm at its end Defining the boundary, wherein in the longitudinal arm a threaded hole continuing in the longitudinal direction of the longitudinal arm is provided, the threaded hole extending to both longitudinal arms to close the receiving opening, a closing bolt can be screwed into the thread In the screwed-in state, the closure bolt engages with threaded holes in the two longitudinal arms, wherein the dimensions of the outer circumference and ring width of the main body are preset. Background technique [0002] Chain joints of the ...
