Connection structure between building blocks and building blocks connected therewith

Abstract

The invention relates to a connecting structure between building blocks and to a building block. The connecting structure according to the invention has a relatively simple structural design so as to be easily producible and releasable. Furthermore the connecting structure allows a quick modification of the orientation of the building blocks relative to one another. In the process an energy and/or information transmission is allowed between the building blocks at the same time.

What is claimed is: 
     
         1 . A connecting structure, comprising:
 connecting devices between building blocks of automation systems,   wherein the connecting structure provides an energy or information connection between two building blocks connected by the connecting devices,   wherein the connecting structure provides a friction locking or form locking plug connection between two building blocks connected by the connecting structure or   wherein first magnetic connecting elements are provided, wherein the connecting structure provides a friction locking or form locking connection between two building blocks, wherein the friction or form locking is provided by at least two corresponding connecting elements, and   wherein a first connecting element is rotatably arranged in a second connecting element and one of the first and second connecting elements includes at least one undercut and another corresponding connecting element of the second and first connecting elements includes at least one protrusion corresponding to the undercut.   
     
     
         2 . The connecting structure according to  claim 1 , wherein the connecting structure is configured with a single joint or the connecting structure fixates an orientation of the building blocks relative to each other. 
     
     
         3 . The connecting structure according to one of the preceding claims, wherein the connecting structure is configured so that a connection of the building blocks with one another is facilitated for at least two different orientations of the building blocks relative to each other. 
     
     
         4 . The connecting structure according to  claim 1 ,
 wherein the friction locking or form locking blocks a separation of the building blocks connected with one another by the connecting structure in a first direction,   wherein the friction or form locking in a second direction inclined relative to the first direction at a right angle is provided disengageable,   wherein at least one disengageable lock is provided which fixates the friction or form locking in the second direction,   wherein the lock is provided as at least one device from a group of devices including:   an element insertable into the first and the second building block so that the first and the second building block are connected;   second magnetic connecting elements, and   interlocking devices which are provided under a preload and which are unlockable by actuating a disengagement element.   
     
     
         5 . The connecting structure according to  claim 1 ,
 wherein a first connecting element is arranged at a first building block and a second connecting element corresponding with the first connecting element is arranged at a second building block or   wherein it is provided that each building block includes at least one first connecting element and at least one second connecting element.   
     
     
         6 . The connecting structure according to  claim 5 ,
 wherein the first connecting element is configured pluggable into the second connecting element, and   wherein it is advantageously provided that the first connecting element includes n-fold rotation axes wherein and >0, in particular n=4.   
     
     
         7 . The connecting structure according to  claim 1 , wherein the first connecting element is configured rotatable by 360° in the second connecting element. 
     
     
         8 . The connecting structure according to  claim 6 , wherein at least one first connecting element and at least one second connecting element of the connecting structure is configured electrically conductive. 
     
     
         9 . The connecting structure according to  claim 1 , wherein at least one slip contact is provided or an energy connection or an information connection is configured so that a first polarity is provided for at least a first orientation of the building blocks relative to one another and a second polarity is provided at least for a second orientation. 
     
     
         10 . A building block of an automatic system,
 wherein the building block includes the connecting structure according to  claim 1 ,   wherein the building block includes at least one side surface which is configured rectangular, square or circular.   
     
     
         11 . A connecting structure, comprising:
 connecting devices between building blocks of automation systems,   wherein the connecting structure provides an energy and information connection between two building blocks connected by the connecting devices,   wherein the connecting structure provides a friction locking and form locking plug connection between two building blocks connected by the connecting structure, and   wherein first magnetic connecting elements are provided, wherein the connecting structure provides a friction locking and form locking connection between two building blocks, wherein the friction and form locking is provided by at least two corresponding connecting elements, and   wherein a first connecting element is rotatably arranged in a second connecting element and one of the first and second connecting elements includes at least one undercut and another corresponding connecting element of the second and first connecting elements includes at least one protrusion corresponding to the undercut.
