Abstract

Toggle retainers are disclosed for toggle connection assemblies of conveyor pans of a chain scraper conveyor or guide troughs of a mining machine guide used in underground mining operations. The toggle retainers feature laterally open toggle pockets into which toggles can be readily inserted. The toggles have toggle heads that are connected in one piece with one another, with at least one of the toggle heads having a bolt tongue. A toggle retainer can be affixed to one of the toggle pockets by extending the retainer under one or more wall projections. The toggle retainer is designed so as to have multiple parts, with a bolt element, in the assembled state, extending over the bolt tongue and under the wall projections. To ensure a secure placement of the toggle in the toggle pockets, a filler element can be form-fittingly inserted between the bolt element and the back wall of the toggle pocket and connected to the bolt element via a screw joint.
