Abstract: A hinged connection between a removable housing closure and a stationary housing part, wherein a terminal configuration of the housing closure has a convex molding, with a web that is contiguous with the molding and which web has a tapering cross section. Adjacent to the web there is an indentation, in which a convex molding that is on the stationary housing part and is offset at an angle of 90 degrees from a projecting leg and is connected to the projecting leg by a contiguous web that has a tapering cross section is engaged. The housing closure can thereby be pivoted with respect to the stationary housing part and re-engaged with it. Additionally, when the housing is closed, no parts project either inside or outside in the vicinity of the housing closure and the stationary housing part.

Abstract: An attachment device for a glass pane presenting voltaic cells, at a mounting fixed to a structure, whereby the glass pane is hold between two clamping elements. The invention concentrates on the fact that a coupling bell is supported with adjustable initial tension at the inside clamping element, while a permanently elastic spring member is placed between the coupling bell and the inside clamping element tolerating a relative motion of the coupling bell with regard to the clamping element. The invention concentrates furthermore on the execution of several spatial articulations and between the glass pane and the mounting fixed to a structure, as well as on the realization of the current conduction passing through the attachment device.

Abstract: Pivot-hung door drive system with an electronic control system that contains at least one memory and one microprocessor, for an at least single-panel door, the door panel of which is driven by an electro-mechanical drive unit that acts in the opening and closing directions. The drive unit consists essentially of a drive motor with a transmission and a power transmission unit for the door connected to it, whereby the power transmission unit consists of a drive shaft which is connected with one end of an actuator lever and the pivot-hung door drive system is installed inside a door panel or inside a door frame or casing. The power transmission unit consists of a screw with a nut that partly surrounds it, which nut is positively and non-positively connected to a toothed rack, whereby the drive shaft is engaged with its gear teeth in the gear teeth of the toothed rack.

Abstract: Door system with a locking device which has top and bottom locking elements which can be displaced by a drive unit to realize a door system which is simple and easy to install, whereby the functional and operational reliability of the system are increased. For this purpose, associated with each of the top and bottom locking elements is an actuator element whereby the actuator elements are fastened to a single slide which is held on a beam so that it can move perpendicular to the sliding direction of the leaf and which can be moved indirectly by the drive unit.

Abstract: A fastening of end caps to housings that are made of profiles and are used for door-specific devices on automatically operated doors. The end caps are thereby invisibly clipped or clipped in a concealed manner onto installation elements that have previously been connected with the sections, whereby at least one of the installation elements is simultaneously used as a fastening for the housing.
