The multifunctional housing within the scope of the invention is used to branch out signals for telephone and Internet that arrive from a switching center and assign them to several individual households. A fiber optic cable is laid between the switching center and the multifunctional housing, which conducts optical signals. Cables to the individual connections in the corresponding households are laid between the multifunctional housing and the households. A piece of technology (DSLAM (Digital Subscriber Line Access Multiplexer), MSAN (Multi-service Access Node) or similar) is arranged in the multifunctional housing, which converts optical signals from the fiber optic cable into electrical impulses converts. In addition, the multifunctional housing can have a power connection and/or a battery for an emergency supply. In addition, the multifunctional housing can have an anti-theft mechanism and/or an alarm system.

The multifunction housing can also have an air conditioner, which is preferably equipped with a cooling system, such as. B. a fan, and / or a heater can be performed. In addition, the multifunctional housing can have a filter system for the outside air. The air conditioning and/or filtration system can be placed under the cover so that inspection of this part is only possible when the cover is removed from the housing and lifted.

With the help of the invention, an advantageous system with a lifting device for the cover of the multifunctional housing can be provided, which allows a cover of a multifunctional housing to be lifted easily and without great assembly effort. This preferably makes inspection or maintenance of the multifunctional housing considerably easier, minimizes the risk of injury and reduces manpower. Advantageously, the lifting device can be used as standard for different multifunctional housings. Furthermore, it is advantageous that the lifting device can be assembled easily and without great assembly effort, and can be operated easily and safely by just one fitter.

Furthermore, the support unit for hanging the lifting device can be performed on a lower sill section of the housing frame of the multifunctional housing. In this way, the lifting device can be attached directly to the housing frame of the multifunctional housing in a simple, safe and stable manner.

Furthermore, the support unit can be designed for positive and/or non-positive attachment of the lifting unit, in particular the actuating unit. In this way, the lifting unit can be detached from the support unit easily and without great assembly effort. The ability to detach the lifting unit from the support unit allows for a compact lifting device for transport. At the same time, this allows the lifting device to be assembled easily and without great assembly effort, in particular by just one worker.

Furthermore, it is conceivable that the support unit has a metal, in particular a heavy metal, preferably iron. In this way, the support unit can be used to hang the lifting device securely and stably directly on the housing frame of the multifunctional housing.

In addition, the support unit can be designed as a separate construction module for the lifting unit. In this way, a modularly constructed lifting device can be provided, which can preferably be easily dismantled for transport.

In addition, the lifting unit can be fastened to the support unit in a height-adjustable manner. In this way, the lifting device can be easily and conveniently adapted to different heights of different multifunctional housings.

In addition, the lifting unit can be fastened to the support unit with a positive and/or non-positive fit. In this way, the lifting unit can be detachably attached to the support unit. Transport can be simplified by being able to detach the lifting unit from the support unit. In addition, the assembly of the lifting device can thereby be simplified. In addition, an adjustable attachment of the lifting unit to the support unit can thereby be made possible. Consequently, the lifting device can be easily and conveniently adapted to different heights of different multifunctional housings.

For reasons of weight reduction, the lifting unit can be made of a metal, in particular a light metal, preferably aluminum.

Advantageously, the lifting device can generally be modular, in particular in the form of a kit system. In this way, the dismantling of the lifting device can be made possible, so that the individual parts of the lifting device can be stowed away more easily and without taking up much space, preferably for simplified transport of the lifting device.

According to a further advantage, the lifting unit can be designed specifically in a modular manner, in particular in the form of a kit system. This can also facilitate the dismantling of the lifting device, so that the individual parts of the lifting device can be easily and conveniently put together for transport.

Furthermore, the support unit can have at least one, in particular two, preferably U-shaped, feet for positively arranging on a lower threshold element of the housing frame of the multifunctional housing. In this way, the lifting device can be hung directly on the housing frame of the multifunctional housing.

Furthermore, the support unit may have a hanging portion for abutting against a side face of a lower sill portion of the body frame of the multifunction case. In this way, the lifting device can be suspended in a supportive manner on the housing frame of the multifunctional housing.

Furthermore, it can be advantageous for the actuation unit to have an actuation lever, in particular a rotatable actuation lever, for actuating the transmission unit. In this way, the lid can be lifted more easily, since a single fitter simply needs to turn the actuating lever in order to be able to lift the lid easily and without great effort.

Furthermore, the actuating unit can have a centering element, in particular in the form of a centering screw, for fixing the actuating unit, in particular a lifting column actuating unit, in particular in a height-adjustable manner on the support unit, in particular in a receiving section of the support unit. In this way, the lifting unit can be fastened to the support unit in a stable and height-adjustable manner in a simple and convenient manner.

In addition, the actuating unit can have a support element, in particular in the form of a support bolt, for supporting a lifting column against an upper threshold section of the housing frame of the multifunctional housing. In this way, not only can the weight of the lifting unit be supported against the housing frame of the multifunctional housing, but also the weight of the cover.

In addition, the transmission unit can have a cable system (in particular a pulley system), a chain system and/or a lever system. In this way, a stepless transmission of force between the actuating unit, in particular the actuating lever, and the coupling unit can be made possible in order to be able to lift the cover.

In addition, the transfer unit can have at least one deflection roller. With the aid of the deflection roller, the force can be transmitted via a lifting frame, in particular a crane-shaped one. The power can be transmitted in such a way that the actuating force for lifting the cover is reduced.

For stable hanging of the lid on the, in particular crane-shaped, lifting frame, preferably on a support column of the lifting frame, the deflection roller can be rotatably mounted on the lifting frame, preferably on the support column of the lifting frame.

Furthermore, the transfer unit can have a winding roller. It can be advantageous if the winding roll can be fastened in a rotationally fixed manner to an actuating lever, in particular a rotatable actuating lever, in order to be able to rotate preferably together with the actuating lever to actuate the transmission unit. In this way, a winding or unwinding of a rope can be made possible in a transmission unit, whereby the Lid is lifted or lowered accordingly.
