Abstract

A stack arrangement having at least two stack elements, which can be stacked on each other in a stacking direction, of which at least one is formed from a transport container which has a container body having a storage receptacle which has a machine receptacle for an electrical or pneumatic hand tool machine. The stacking elements have bus interfaces for transferring data and/or energy between the stacking elements of the stack arrangement, wherein the bus interfaces form a bus connection between the stack elements when the stack elements are stacked on each other.

First claim

The invention claimed is:

1. A stack arrangement having at least two stack elements, which can be stacked on top of one another in a stacking direction, of which at least one is represented by a transport container having a container body and a storage receptacle with a machine receptacle for an electric or pneumatic hand-operated power tool, wherein the stack elements have bus interfaces for transmitting data and/or energy between the stack elements of the stack arrangement, wherein the bus interfaces form a bus connection in a side wall section of the container body and communicate between the stack elements when the stack elements are stacked on top of one another or in the stacked state of the stack elements; and the bus connection having a feed-in interface and configuring to connect to an external computer, wherein at least one stack element of the stack arrangement has mutually connected bus interfaces, provided for communication with a stack element placed below or above, so that the stack element located in the stack arrangement establishes the bus connection between the upper and the lower stack elements, and wherein the bus interface of the transport container is connected to a machine interface for the connection of a service interface of the hand-operated power tool, and wherein the machine receptacle is provided in a container insert, which is supported on a base of the storage receptacle and is securable against a movement along the base using fastening means, and is supported on at least one circumferential side wall laterally bounding the storage receptacle, wherein connecting means which are connected to the bus interface when the container insert is placed in the storage receptacle are provided on the container insert for establishing the connection between the machine interface and the service interface of the hand-operated power tool.

2. The stack arrangement according to claim 1 , wherein the machine interface is provided for transmitting data or electric energy or compressed air.

3. The stack arrangement according to claim 1 , wherein the machine interface comprises a wireless transmission interface for the wireless transmission of data and/or energy and/or connecting contacts for establishing a contact-based connection to the hand-operated power tool.

4. The stack arrangement according to claim 1 , wherein at least one bus interface provided between two stack elements comprises a wireless bus interface provided for data and/or energy transmission or a wireless bus interface provided for data transmission or energy transmission only.

5. The stack arrangement according to claim 1 , wherein the bus interfaces provided for wireless transmission of energy, are in alignment with one another in the stacked state of the stack elements, and/or wherein coupling means of stacked stack elements, which are designed for wireless communication, are located on walls or in wall regions of the stacked stack elements, which are immediately opposite one another and/or are held in a stable position relative to one another by coupling means connecting the stack elements in a manner resistant to tension in the stacking direction and/or by positive-locking contours of the stack elements providing positive engagement transverse to the stacking direction.

6. The stack arrangement according to claim 1 , wherein the bus interfaces comprise electric contact surfaces, which are located on plug connectors, on the top side of a lower stack element and on the underside of an upper stack element stacked on top of the former, which contact surfaces are oriented on the respective underside or top side in such a way that they establish the bus connection as the stack elements are stacked.

7. The stack arrangement according to claim 1 , wherein a plug-in axis of the plug connectors extends parallel to the stacking direction, so that the plug connectors can be plugged into one another by stacking one stack element on top of another stack element.

8. The stack arrangement according to claim 1 , wherein the bus interfaces comprise at least one link, which joins an upper stack element to a lower stack element of the stack arrangement and is in the assembled state joined to a side wall section of the container body of the upper stack element and to a side wall section of the container body of the lower stack element.

9. The stack arrangement according to claim 8 , wherein the at least one link is movably mounted on one of the stack elements or comprises plug-in means for plugging into at least one of the stack elements.

10. The stack arrangement according to claim 8 , wherein the at least one link comprises a rotatably mounted lock element, which locks together two stack elements in a locking position and releases the stack elements in a release position, wherein the lock element is in electric contact with bus contacts of the stack elements joined by the lock element and electrically connects them in the locking position and is out of contact with the bus contacts in the release position and/or positions transmission means of the stack elements designed for wireless data or energy transmission in the locking position relatively closer to one another than in the release position.

11. The stack arrangement according to claim 1 , wherein at least one of the stack elements has a wireless or line-based connection for an electric energy network, for feeding electric energy and/or compressed air into the bus connection and/or a communication interface, which comprises a plug connector for the wireless or line-based connection of the bus connection to a local area network, and/or for communication with a control.

12. The stack arrangement according to claim 11 , wherein the feed-in interface comprises a transformer, for the provision of a supply voltage suitable for an electric hand-operated power tool stored in the stack arrangement using the electric energy or compressed air fed in via the feed-in interface.

13. The stack arrangement according to claim 1 , wherein at least one of the stack elements of the stack arrangement comprises an exchangeable energy store for the provision of electric energy on the bus connection and/or a control for controlling data input and/or data output, at least one hand-operated power tool stored in a transport container and connected to the bus connection.

14. The stack arrangement according to claim 1 , wherein the at least one transport container comprises at least one charging station, which is wireless or has charging contacts for a hand-operated power tool, and/or a battery pack, which is separate from the hand-operated power tool.

15. The stack arrangement according to claim 1 , wherein the at least one transport container comprises at least one sensor for the detection of a number of operating hours and/or a service interval and/or information on a malfunction and/or a charging state of an energy store of the hand-operated power tool, and/or wherein a sensor is provided in the transport container for detecting the amount of consumables present in the transport container.

16. The stack arrangement according to claim 1 , wherein at least one stack element of the stack arrangement comprises a location device for the wireless location of the stack element or the stack arrangement using a control.

17. A stack arrangement comprising: a lower stack element having a bus interface disposed on a top side of the lower stack element; an upper stack element stacked on top of the lower stack element in a stacking direction and having a bus interface on an underside of the upper stack element, the bus inter
