Joint bar arrangement for a joint bar lock and a joint bar lock

Abstract

A joint bar arrangement for a joint bar lock comprises a plurality of joint bars connected to one another in series according to a defined sequence, including a first joint bar and a last joint bar according to the sequence, each extending along a longitudinal extent from a first end section to a second end section, and each joint bar, with the exception of the last joint bar, is coupled with its second end section via a respective joint connection to the first end section of the subsequent joint bar according to the sequence, in such a way that it can be pivoted relative to the subsequent joint bar about a joint axis of the respective joint connection which is orthogonal to its longitudinal extent. Each of the joint bars is bound with respect to a transverse extent, orthogonal to its longitudinal extent and to the joint axis of the respective joint connection, by two opposite longitudinal sides which are thickened, at least in sections, namely, at least insofar as it is not the first joint bar, in the entire first end section of the respective joint bar and, at least insofar as it is not the last joint bar, in the entire second end section of the respective joint bar, the longitudinal sides are thickened insofar that they have a greater expanse in a direction parallel to the joint axis of the respective joint connection than an in-between central region of the respective joint bar.
