Definitions

  • the present invention relates to a connecting structure between structural elements according to the preamble of claim 1 and a structural element according to the preamble of claim 15.
  • Design elements are known, for example, as passive components / modules or as active modules (actuators) of automated systems, where they preferably form robots.
  • each module has a continuous electrical and information connection with every other module. This coupling is made by means of a jack plug connection.
  • the spatial definition of the modules to each other by means of a magnetic connection, which consists of four pairs of magnets, which are arranged at 90 ° -Winkelabplacen to each other, so that the square base surfaces of the modules can be arranged in four different orientations to each other. In the interposed 45 ° positions, the modules can be easily detached from each other.
  • a disadvantage of this embodiment is that while the magnetic connection holds a certain load in the direction of the magnetic effect, it is very susceptible to shear forces or forces oriented perpendicularly to the magnetic action, as a result of which the coupling could also be damaged.
  • the magnetic forces can not be increased arbitrarily, since electromagnets usually can not be used, or their increase hinders the solubility of the modules.
  • a disadvantage of this embodiment is that a change in the orientation of the modules to each other only very cumbersome and using tools for releasing the clasp is possible.
  • the object of the present invention is therefore to provide a connecting structure which overcomes these disadvantages.
  • it should be structurally relatively simple, so that they can be easily produced and solved again.
  • it should preferably allow a rapid change in the orientation of the structural elements to each other.
  • it should be made possible at the same time preferably an energy and / or information transmission between the construction elements.
  • the US 2005/007 780 A1 discloses a modular lighting connection system in which individual lamp blocks have connecting means of identical type.
  • connection construction provides a non-positive and / or positive connection between two associated construction elements and / or that ii) the connection construction a force and provides positive connection between two associated construction elements and further provided first magnetic connection elements. Due to the non-positive and / or positive plug connection, a resistance is opposed, at least in one direction perpendicular to the connecting plane between the structural elements of the separation of the connection of the construction elements. Because this is a plug connection, this connection is particularly easy to produce.
  • the connecting structure is formed einbindig. This makes it particularly easy to use.
  • connection engages in certain positions, for example 90 ° angle positions, but it is possible to join them together from all positions.
  • the connecting structure determines the construction elements in their orientation to each other. As a result, a rotation of the construction elements is prevented relative to each other and the overall structure can thus transmit rotational forces.
  • the connecting structure is designed such that a connection between the construction elements for at least two different orientations of the construction elements to each other is possible. This allows the user to easily create different orientations without having to provide different design elements.
  • “Direction” in this context means not only linear direction but also direction of rotation.
  • At least one releasable barrier is provided which fixes the force and / or positive locking in the release direction.
  • the materials and material thicknesses must be interpreted in accordance with the load.
  • the barrier is at least designed as a means selected from the group of the following means: i) a member insertable into the first and second structural members, ii) second magnetic fasteners, and iii) latching means which are preferably biased and can be unlocked by actuation of a release element. Then the lock can be implemented very easily.
  • the second magnetic fasteners these are of course not a mechanical barrier, but one in the context of the magnetic effect.
  • the force and / or positive connection is provided via at least two mutually corresponding connecting elements, wherein it is preferably provided that a first connection element is arranged on a first construction element and a connecting element corresponding thereto on a second construction element and / or is preferably provided that each construction element has at least a first connection element and at least one second connection element.
  • the construction element has both types of connecting elements and can thus be assembled with identical construction elements.
  • the first connection element is designed to be insertable into the second connection element.
  • the second connection element is also designed to be insertable into the first connection element.
  • n 4
  • the first connecting element is rotatable, in particular rotatable about 360 °, in the second connecting element. Then the orientation of the construction elements with each other can be changed very easily without having to solve their connection.
  • one of the first and second connecting elements has at least one undercut and the corresponding other of the second and first connecting elements has at least one corresponding to the undercut projection.
  • the electrical or information connection can then be realized in a particularly simple manner if at least a first and a second connecting element of the connecting structure is designed to conduct electricity.
  • At least one sliding contact preferably 3 or 4 sliding contacts can be provided.
  • indirect contacts based on transmission by means of transmitters and receivers, such as IR transmitters and IR receivers, may be used.
  • the energetic and / or information connection is designed such that there is a first polarity relative to one another for at least one first orientation of the construction elements and a second polarity exists for at least one second orientation. Then by changing the orientation of the construction elements with each other, an action of an actuator connected to the construction elements (which provides at least one of the effects of length change, rotation, pivoting, etc.) can be changed without having to undertake any special reprogramming.
