Abstract: The invention relates to a roller shutter box with a slat inlet and a centre bearing located between the two head pieces as well as an inspection cover, whose slat inlet in the head piece can be pushed parallel to the longitudinal axis of the roller shutter box or of the roller shutter shaft into any position and whose slat inlet can be pushed variably on the outer panel in a guiding groove parallel to the roller shutter shaft or the longitudinal axis of the roller shutter box and that is secured to an outer panel by means of a guide and fastening bracket of the slat inlet.

Abstract: The invention concerns a container, such as a residential container, for instance, with built-in windows, doors, etc., which can be equipped with shutter frames and shutters, in which the connection of the container wall opening to the window frame is effected by means of an interposed, wraparound installation frame, which is connected mechanically to the window frame or shutter frame, on the one hand, and to the edge of the container wall opening, on the other hand.

Abstract: The device is a section connector for building structures, such as, for instance, a rafter assembly section connector for winter gardens or the like, with the aid of which a hollow section can be attached to another hollow or solid section at variable angles. An inset equipped with a ball head is firmly attached to one section. Using the ball head, the inset is connected to a structural part attached to another section in such a way that it can pivot.

Abstract: A window or a door has a frame structure and a U-shaped bar simultaneously serving as reinforcement section and a turn-tilt mechanism.

Abstract: The apparatus includes a hollow chamber, preferably made from a synthetic material, such as PVC or other plastic, with an insertable reinforcement piece suitable for connecting to window, door or other configurations, such as abutment and frame profiles. The reinforcement piece comprises a unitary rolled sheet metal with one or more screw channels within the reinforcement profile for a front face abutment screw connection. The reinforcement piece further includes at least one shank inwardly extending from the screw channel toward the opposite chamber wall. The reinforcement piece further includes a shank extending around the inner walls of the hollow chamber.
