Abstract: Adjustment device for a support arm system, support arm system includes a support arm for holding an object, a hinge part having a receiving portion for securing the support arm, and the hinge part being rotatably mounted on a hinge retainer. Support arm is securable with an end face to the hinge part, and a deployment angle of the support arm being adjustable using adjustment device which is formed from a wedge-shaped adjustment head that interacts with a slide incline of the hinge part and the end face of the support arm. Adjustment head includes a wedge surface and a pressure surface that lies opposite wedge surface, and adjustment head is adjustable such that the wedge surface slides along on the slide incline and pressure surface therefore pressing against end face of the support arm such that the deployment angle of the support arm can be adjusted.

Abstract: A housing, especially for accommodating electrical and electronic components, comprising a lower portion, a cover adapted to be secured to the lower portion, and a holding element adapted to be mounted on a planar surface. The lower portion, along with the cover secured thereto, is adapted to be releasably arrested on the holding element, under spring tension.

Abstract: An enclosure for electrical and electronic components comprising a lower part and a cover that can be fastened thereto by a screw connection. Fastening channels are provided in the lower part parallel to screwing locations, via which the enclosure can be fastened to a support. The fastening channels continue inside the cover and open to the exterior so that the enclosure can be fastened to the support when the cover is already fastened to the enclosure lower part.

Abstract: The present invention relates to a housing for the installation of electrical components comprising a lower section and a cover connected to each other in a hinged manner by at least two flexible inner elements separated from each other outside the housing interior. The ends of the inner elements have a greater cross-section than the region lying between said ends and at least one of the ends is elastically embodied for a temporary reduction in cross-section. Openings leading into each other are provided in the cover and in the lower section, the cross-section of which permits access of the at least one end in the compressed state.
