Abstract: A hinge for a hinged opening of a vehicle includes a first hinge part and a second hinge part which are connected to one another via an axis of rotation so as to be movable relative to one another. The first hinge part has a slot and the second hinge part has a fitting hole. A screw is received through the slot of the first hinge part and fitting hole of the second hinge part. A shaped nut clamps the first hinge part and the second hinge part against the screw. The shaped nut forms a step that includes a first part received in the slot and a second part protruding from the first hinge part and resting on an edge of the slot.

Abstract: The invention relates to a building block system having modules that can be plugged together, wherein electronic and mechanical components required for motion and control are provided in the modules. The object of the invention is to provide a building block system, which facilitates constructing mobile models from simple building blocks. According to the invention, the object is achieved by a building block system having movable modules, wherein the building block system includes at least one energy module, at least one control module having a micro-controller, at least one movement module having an integrated servo motor, and a plurality of connection modules that can be randomly connected with each other, wherein the modules are connectable through plug connections enabling current flow between adjacent modules.
