Description

[0001] The invention relates to a system, a lifting device and a method for lifting a cover of a multifunctional housing.

[0002] Multifunctional enclosures are generally known from the state of the art. These enclosures are used to branch telephone and internet signals arriving from a central office and allocate them to several individual households. A fiber optic cable runs from the central office to the multifunctional enclosure. Several cables lead from the multifunctional enclosure to the individual connections in the corresponding households. The multifunctional enclosure contains more complex technology that converts optical signals from the fiber optic cable into electrical impulses. The multifunctional enclosure also has its own power connection. The multifunctional enclosure also features an air conditioning system and a filter system for the often polluted outside air, which are located under a cover.

[0003] To check and / or repair the installed technology, the multifunctional enclosures are regularly inspected and / or serviced. Currently, two technicians are required for inspection and maintenance. To inspect or service a multifunctional enclosure, a cover must be removed from the enclosure. Due to the weight and size of the cover, its removal requires several technicians. However, manually removing the cover carries a risk of injury. Furthermore, the cover can be dropped and damage the installed technology, such as the filter system and / or air conditioning system. Consequently, the inspection and maintenance of multifunctional enclosures involves a significant amount of disassembly work.

[0004] DE 20 2004 008 710 U1 describes a device for lifting a tank lid. WO 99 / 35 077 A1 discloses a foldable crane for mounting on the body of a vehicle, and DE 202 07 119 U1 shows a seamless lifting device for use in environments with corrosive media, such as sewage treatment plants.

[0005] The object of the present invention is to at least partially remedy the above-mentioned disadvantages known from the prior art. In particular, the object of the present invention is to facilitate and / or standardize the lifting of a cover of a multifunctional housing. Preferably, the object of the present invention is to simplify and facilitate the inspection or maintenance of a multifunctional housing, minimize the risk of injury, and reduce the manpower required.

[0006] The above object is achieved by a system having the features of the independent system claim, a lifting device having the features of the independent device claim, and a method having the features of the independent method claim. Further features and details of the invention emerge from the respective subclaims, the description, and the drawings. Features and details described in connection with different aspects of the invention naturally also apply in connection with the other aspects of the invention, so that reciprocal reference is or can always be made to the individual aspects of the invention with regard to the disclosure.

[0007] According to a first aspect, the invention provides a system comprising: - a multifunctional housing for distributing telephone and / or Internet signals from an exchange to several households, and - a lifting device for lifting a cover of the multifunctional housing.

[0008] The lifting device has the following units: - a support unit for supporting the lifting device on a housing frame of the multifunctional housing, - a lifting unit for lifting the lid.

[0009] The lifting unit has the following units: - a coupling unit for coupling with the lid, - an actuating unit for transferring the lid between: - a rest position in which the cover is arranged on the multifunctional housing, and - an operating position in which the cover releases the multifunctional housing for inspection, and - a transmission unit for transmitting power from the actuating unit to the coupling unit.

[0010] The multifunctional housing within the scope of the invention serves to branch out telephone and internet signals arriving from a central office and assign them to several individual households. A fiber optic cable is laid between the central office and the multifunctional housing, which transmits optical signals. Cables are laid between the multifunctional housing and the households to the individual connections in the corresponding households. The multifunctional housing contains technology (DSLAM (Digital Subscriber Line Access Multiplexer), MSAN (Multi-service Access Node) or similar) that converts optical signals from the fiber optic cable into electrical impulses. Furthermore, the multifunctional housing can have a power connection and / or a battery for emergency power supply. Furthermore, the multifunctional housing can have an anti-burglary mechanism and / or an alarm system.

[0011] The multifunctional housing can further include an air conditioning system, which can preferably be implemented with a cooling system, such as a fan, and / or a heater. Furthermore, the multifunctional housing can include a filter system for the outside air. The air conditioning system and / or the filter system can be arranged under the cover, so that inspection of these parts is only possible when the cover is removed from the housing and lifted.

[0012] The invention provides an advantageous system with a lifting device for the cover of a multifunctional housing, which allows the cover of a multifunctional housing to be lifted easily and without major assembly effort. This can significantly facilitate inspection and maintenance of the multifunctional housing, minimize the risk of injury, and reduce the required personnel effort. Advantageously, the lifting device can be used as a standard for various multifunctional housings. Furthermore, it is advantageous that the lifting device can be assembled easily and without major assembly effort, and can be operated easily and safely by a single technician.

[0013] Furthermore, the support unit for suspending the lifting device can be mounted on a lower sill section of the housing frame of the multifunctional housing. This allows for simple, secure, and stable attachment of the lifting device directly to the housing frame of the multifunctional housing.

[0014] Furthermore, the support unit can be designed for positive and / or non-positive fastening of the lifting unit, in particular the actuating unit. This allows the lifting unit to be removed from the support unit easily and without major assembly effort. The ability to remove the lifting unit from the support unit enables a compact lifting device for transport. At the same time, the lifting device can be assembled easily and without major assembly effort, especially by a single worker.

[0015] Furthermore, it is conceivable for the support unit to comprise a metal, in particular a heavy metal, preferably iron. In this way, the support unit can serve to securely and stably suspend the lifting device directly from the housing frame of the multifunctional housing.

[0016] In addition, the support unit can be designed as a separate module from the lifting unit. This provides a modular lifting device that can be easily disassembled for transport.

[0017] In addition, the lifting unit can be attached to the support unit in a height-adjustable manner. This allows the lifting device to be easily and conveniently adapted to the different heights of various multifunctional enclosures.

[0018] Furthermore, the lifting unit can be attached to the support unit with a positive and / or non-positive fit. This allows the lifting unit to be releasably attached to the support unit. The ability to remove the lifting unit from the support unit simplifies transport. Furthermore, this simplifies the assembly of the lifting device. Furthermore, it allows for adjustable attachment of the lifting unit to the support unit. Consequently, the lifting device can be easily and conveniently adapted to different heights of various multifunctional enclosures.

[0019] For reasons of weight reduction, the lifting unit can be made of a metal, in particular a light metal, preferably aluminum.

[0020] Advantageously, the lifting device can generally be designed in a modular manner, particularly in the form of a kit system. This allows for disassembly of the lifting device, allowing the individual parts of the lifting device to be stored more easily and without taking up much space, preferably for simplified transport of the lifting device.

[0021] Another advantage is that the lifting unit can be designed in a modular manner, particularly in the form of a kit system. This also facilitates disassembly of the lifting device, allowing the individual parts of the lifting device to be easily and conveniently assembled for transport.

[0022] Furthermore, the support unit has at least one, in particular two, preferably U-shaped, feet for positively arranging them on a lower threshold element of the housing frame of the multifunctional housing. This allows the lifting device to be suspended directly from the housing frame of the multifunctional housing.

[0023] Furthermore, the support unit alternatively or additionally has a hanging section for resting against a side surface of a lower threshold section of the housing frame of the multifunctional housing. This allows the lifting device to be suspended from the housing frame of the multifunctional housing in a supporting manner. It also allows the weight of the lifting device to be supported against the housing frame of the multifunctional housing.

[0024] The support unit also includes a support platform for supporting the lifting device. The support platform can be used to provide a supporting surface for attaching the lifting unit.

[0025] In addition, the support unit alternatively or additionally has a receiving section, in particular a sleeve-shaped and / or cylindrical shell-shaped and / or tubular, e.g., round or square in cross-section, for receiving the lifting unit, in particular the actuating unit, in particular in a form-fitting and / or force-fitting manner. This enables a simple, in particular form-fitting and / or force-fitting, and thus detachable, attachment of the lifting unit to the support unit.

[0026] Furthermore, the coupling unit can be provided with at least one, in particular several, gripping hooks for coupling to the lid, in particular for engaging ventilation slots on the lid. This allows the coupling unit to be easily hooked onto the lid to lift the lid.

[0027] For the sake of simplicity, the coupling unit may have a suspension system, in particular a rope-shaped one, for suspending the cover from the actuating unit.

[0028] Advantageously, the actuating unit can comprise a lifting frame, in particular a crane-shaped one, for positive and / or non-positive fastening to the support unit, in particular in a receiving section of the support unit. In this way, the lifting device can facilitate lifting of the lid.

[0029] Furthermore, the lifting frame can comprise a lifting column and a support column. Thus, the lifting frame can be positioned in front of the housing and above the cover to enable the cover to be lifted.

[0030] Furthermore, it may be advantageous for the actuating unit to have a, particularly rotatable, actuating lever for actuating the transmission unit. This makes it easier to lift the lid, as a single technician simply needs to turn the actuating lever to lift the lid easily and without great effort.

[0031] 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, to the support unit, in particular in a receiving section of the support unit, in particular in a height-adjustable manner. This allows for a stable and height-adjustable attachment of the lifting unit to the support unit.

[0032] In addition, the actuating unit can have a support element, particularly 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 the weight of the lifting unit but also the weight of the cover can be supported against the housing frame of the multifunctional housing.

[0033] Furthermore, the transmission unit can comprise a cable pull system (in particular a pulley system), a chain system, and / or a lever system. This allows for a continuous power transmission between the actuating unit, in particular the actuating lever, and the coupling unit to lift the lid.

[0034] In addition, the transmission unit can have at least one deflection pulley. With the aid of the deflection pulley, the force can be transmitted via a lifting frame, particularly a crane-shaped one. The force can be transmitted in such a way that the actuating force required to lift the lid is reduced.

[0035] In order to stably suspend the cover on the lifting frame, in particular a crane-shaped one, 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.

[0036] Furthermore, the transmission unit can have a winding roller. It can be advantageous if the winding roller can be non-rotatably attached to an actuating lever, in particular a rotatable one, so that it can rotate preferably together with the actuating lever for actuating the transmission unit. This allows a cable to be wound up or unwound in a transmission unit, thereby raising or lowering the cover accordingly.

[0037] Furthermore, the invention provides a lifting device for lifting a cover of a multifunctional housing, comprising: - a support unit for supporting the lifting device on a housing frame of the multifunctional housing, - a lifting unit for lifting the lid, and wherein the lifting unit comprises the following units: - a coupling unit for coupling with the lid, - an actuating unit for transferring the lid between: - a rest position in which the lid closes the multifunctional housing, and - an operating position in which the cover releases the multifunctional housing for inspection, and - a transmission unit for transmitting power from the actuating unit to the coupling unit.

[0038] The lifting device achieves the same advantages described above in connection with the system according to the invention. These advantages are incorporated herein by reference.

[0039] The lifting device is specifically listed to be used in a system as described above.

[0040] Furthermore, the invention provides a method for lifting a lid of a multifunctional housing, comprising the following steps: - Supporting a lifting device, which can be designed as described above, on a housing frame of the multifunctional housing, - Lift the cover using the lifting device to inspect the multifunction housing.

[0041] The method achieves the same advantages described above in connection with the system according to the invention. These advantages are fully incorporated herein by reference. In particular, the method enables a simple and convenient lifting of a cover of a multifunctional housing by a single technician for inspection purposes. Preferably, the method can significantly facilitate inspection or maintenance of the multifunctional housing, minimize the risk of injury, and reduce the required personnel effort.

[0051] Advantageously, the support unit 10 is designed for the positive and / or non-positive fastening of the lifting unit 20, in particular the actuating unit 22. In other words, the support unit 10 can be designed as a separate module from the lifting unit 20 in order to provide a modular lifting device 100.

[0052] The lifting unit 20 can advantageously be attached to the support unit 10 in a height-adjustable manner in order to be able to adapt the lifting device 100 to different heights of various multifunctional housings 200.

[0053] For reasons of stability, the support unit 10 can be made of a metal, in particular a heavy metal such as iron. For reasons of weight reduction, the lifting unit 20 can be made of a metal, in particular a light metal, preferably aluminum.

[0054] In general, the lifting device 100 can be designed modularly, in particular in the form of a kit system. Furthermore, the lifting unit 20 can be designed modularly, in particular in the form of a kit system. The modular design can be advantageous for disassembling the lifting unit 20 from the support unit 10 and disassembling it into its individual parts. In this way, the lifting device 100 can be designed compactly for transport.

[0055] As the Fig. 1 and Fig. 2 further indicate, the support unit 10 can have at least one, in particular two, preferably U-shaped, feet 11 for positively arranging on a lower threshold element 202u of the housing frame 202 of the multifunctional housing 200.

[0056] As the Fig. 1 and Fig. 2 further indicates, the support unit 10 can have a hanging section 12 for resting against a side surface of a lower threshold section 202u of the housing frame 202 of the multifunctional housing 200. Furthermore, the support unit 10 can have a support platform 13 for supporting the lifting device 100. In addition, the support unit 10 can have a receiving section 14, in particular sleeve-shaped and / or cylindrical and / or tubular, for example round or square in cross-section, for receiving the lifting unit 20, in particular the actuating unit 22, in particular in a form-fitting and / or force-fitting manner.

[0057] As the Fig. 1 and Fig. 2, the coupling unit 21 can have at least one, in particular several, gripping hooks 21a for coupling to the cover 201, in particular for engaging ventilation slots on the cover 201. In addition, the coupling unit 21 can have a suspension system 21b, in particular a rope-shaped one, for suspending the cover 201 from the actuating unit 22.

[0058] As the Fig. 1 and Fig. 2, the actuating unit 22 can have a lifting frame 22a, 22b, in particular a crane-shaped one, for positive and / or non-positive fastening to the support unit 10, in particular in a receiving section 14 of the support unit 10. The lifting frame 22a, 22b can have a lifting column 22a and a support column 22b.

[0059] As the Fig. 1 and Fig. 2, the actuating unit 22 can have a, in particular rotatable, actuating lever 22c for actuating the transmission unit 23 in order to facilitate lifting of the cover 201. In this case, a technician simply needs to turn the actuating lever 22c to lift the cover 201.

[0060] As the Fig. 1 and Fig. 2, the actuating unit 22 can have a centering element 22.1, for example in the form of a centering screw, for fixing the actuating unit 22, in particular a lifting column 22a actuating unit 22, to the support unit 10, in particular in a receiving section 14 of the support unit 10, in particular in a height-adjustable manner.
