Abstract: A chain, in particular a technical chain, preferably a unidimensionally movable chain (plate link chain), more preferably a bolt chain or roller chain, has at least one or more chain links. The at least one chain link is constructed with pretensioning. A manufacturing method includes the following steps: assembling at least one chain link from at least two link plates with link plate holes and two bolts or sleeves. In the non-assembled state, the link plate is not straight, in particular has a curved form, and/or the link plate and the link plate holes have a hole axis, wherein the hole axis is not right-angled, and/or, in the non-assembled state, the bolt or the sleeve is not straight, in particular has a curved form. The chain is assembled from at least two chain links and at least one chain link is manufactured in this way.

Abstract: A chain, in particular a conveyor chain for the transport of chassis carriers or bulk goods, contains pairs of exterior tabs, interior tabs and bolts connecting the pairs of exterior link plates and interior link plates to each other. The exterior link plates and/or the interior link plates are at least partially made of plastic.

Abstract: The invention relates to a coupling device for joining a door stop (17) to the hinge (1, 2) of a door of a motor vehicle, especially a door stop (17) consisting of a brake element and a retaining element that is rotationally fixed to one half (1) of the hinge and a retaining housing (18) that is rotationally fixed to the other half (2) of the hinge, whereby the brake element and retaining element is formed by an engaging element with an external peripheral contour that deviates from a pure circular shape and the retaining housing (18) is formed by a hollow profiled section with at least one inner peripheral contour that marks at least one braking or retaining position. The aim of the invention is to provide a coupling device that simplifies the production of and enables the production cost of the semi-hinge and the retaining housing to be reduced, in addition to facilitating assembly of the door stop with one half of the hinge of the door of a motor vehicle.

Abstract: The invention relates to a door stop for motor vehicle doors which is integrated with a demountable door hinge. The door hinge is comprised of two hinge halves (1, 2) and a hinge pin (3) which is accommodated in hinge half (2) with a running fit and in the other hinge half (1) such that it can be lifted off without turning. The door stop comprises braking or holding means which are radially aligned in relation to the hinge pin axis and which interact with stopping means concentrically arranged in relation to the hinge pin axis. The door stop assembly is primarily accommodated in a door stop housing (12). Said door stop housing is placed, in an axial projection (11) of the hinge axis. The hinge pin is mounted with a running fit in the hinge half (2).
