Abstract

The invention relates to a connecting system 1 , comprising at least one hole carrier 2 with a row of side openings 4 made therein in a longitudinal direction, the openings being aligned in a first orientation and in a second orientation orthogonal thereto and being made transverse to the longitudinal direction, wherein the side openings 4 of the first and the second orientation are shifted by one half the distance between two side openings 4 . According to the invention, the distance between two side openings 4 is smaller than the clear width of the side openings 4 , the side opening 4 of the second orientation being made within this distance and the side openings 4 of the first and the second orientation partially penetrating one another. The invention further relates to a method for building an assembly from a connecting system 1 and to a use of a connecting system 1 having the associated securing and connection elements and the installation sequence.

Claims (17)

1 . A connecting system ( 1 ), comprising at least one hole carrier ( 2 ) with a row of a plurality of side openings ( 4 ) made therein in a longitudinal direction, the openings being aligned in a first orientation and in a second orientation orthogonal thereto and being made transverse to the longitudinal direction, wherein the side openings ( 4 ) of the first or the second orientation are shifted by one half a distance between center axes of two adjacent side openings ( 4 ), the connecting system ( 1 ) further comprising at least one round connection element ( 12 ) or at least one cruciform connection element ( 8 ), characterized in that a distance between two adjacent side openings ( 4 ) along the first orientation is less than a thru hole diameter created by a corresponding side opening ( 4 ) along the second orientation, a distance between two adjacent side openings along the second orientation is less than a thru hole diameter created by a corresponding side opening along the first orientation, and the thru holes of the first and the second orientation partially penetrate one another; and

wherein the side openings ( 4 ) have a cross section in which a circular cross section is superimposed by a cruciform cross section in such a way that a contour of the circle is broken up at four places evenly distributed along a periphery.

2 . The connecting system according to claim 1 , wherein at least one end face at a first and/or a second end of the at least one hole carrier ( 2 ) has end openings ( 6 ) with a same cross section as the side openings ( 4 ) or circular cross section alone.

3 . The connecting system according to claim 1 , wherein the at least one hole carrier ( 2 ) has a square cross section with edge length B and rounded edges transverse to the longitudinal direction.

4 . The connecting system according to claim 1 , wherein the at least one cruciform connection element ( 8 ) has a cross section which corresponds to that of the side openings ( 4 ) and/or wherein the at least one round connection element ( 12 ) has a cross section that corresponds to a circular portion of the cross section of the side openings.

5 . The connecting system according to claim 4 , wherein the connection system comprises at least one cruciform connection element, the at least one cruciform connection element ( 8 ) has at least one dual groove ( 10 ) on at least one side surface which extends in a longitudinal direction, a longitudinal side, the at least one dual groove ( 10 ) running transverse relative to the longitudinal direction and a profile of the at least one dual groove ( 10 ) corresponding to an external contour of the longitudinal side of the at least one cruciform connection element ( 8 ), and the at least one dual groove ( 10 ) having a depth which corresponds to a penetration of the side openings ( 4 ) of the first and the second orientation.

6 . The connecting system according to claim 5 , wherein the at least one cruciform connection element ( 8 ) has two dual grooves ( 10 ) and the at least one round connection element ( 12 ) has two dual annular grooves ( 14 ) and a length which is equal to twice an edge length B, a contour of the dual grooves ( 10 ) and the dual annular grooves ( 14 ) corresponding to a surface contour of the cruciform connection element ( 8 ), and a distance between the two dual grooves ( 10 ) or the two dual annular grooves ( 14 ) being equal to the edge length B.

7 . The connecting system according to claim 4 , wherein the connection system comprises at least one round connection element ( 12 ), the at least one round connecting element ( 12 ) has at least one dual annular groove ( 14 ) which runs along an outside surface in a circular fashion, and a profile of which corresponds to an outer contour of a longitudinal side of the at least one cruciform connection element ( 8 ), the at least one dual annular groove ( 14 ) having a depth which corresponds to a penetration of the side openings ( 4 ) of the first and the second orientation.

8 . The connecting system according to claim 1 , wherein at least one securing connector ( 34 ) is provided which has a securing pin ( 31 ) at each of its two ends, at least one of which is designed as a round pin ( 27 ) or a cruciform pin ( 29 ), both provided for insertion into a side opening ( 4 ), or as a securing pin ( 31 ) for insertion into an end opening ( 6 ).

9 . The connecting system according to claim 1 , wherein the at least one hole carrier ( 2 ) has a square cross section with edge length B, and wherein a blocking element ( 16 ) and/or a securing blocking element ( 18 ) is included whose cross sectional shape corresponds to that of the side openings ( 4 ) and whose length is equal to the edge length B.

10 . The connecting system according to claim 1 , wherein a pull-out preventer ( 22 ) is included for the cruciform connection element ( 8 ) and/or for the round connection element ( 12 ), the cruciform connection element ( 8 ) and/or the round connection element ( 12 ) having a securing receptacle ( 20 ).

11 . The connecting system according to claim 1 , wherein an angle piece ( 26 , 28 , 30 ) is provided which has at least two pins ( 27 , 29 , 31 ) which are aligned perpendicular with respect to one another.

12 . The connecting system according to claim 11 , wherein the angle piece is designed as a round connector angle piece ( 26 ) and has at least one round pin ( 27 ) as a pin, or wherein the angle piece is designed as a cross connector angle piece ( 28 ) and at least one cruciform pin ( 29 ) as a pin, or wherein the angle piece is designed as a securing connector angle piece ( 30 ) and at least one securing pin ( 31 ) as a pin.

13 . A method for building an assembly ( 40 ) from a connecting system ( 1 ) according to claim 1 , characterized in that a rotationally fixed connection of at least two hole carriers ( 2 ) is accomplished using the cruciform connection element ( 8 ) which is inserted into one side opening ( 4 ) of each one of the at least two hole carriers ( 2 ), that a rotatable connection of the at least two hole carriers ( 2 ) is accomplished using the round connection element ( 12 ) which is inserted into one side opening ( 4 ) or one end opening ( 6 ) each of each one of the at least two hole carriers ( 2 ), wherein a securing against pull-out of the cruciform connection element ( 8 ) or of the round connection element ( 12 ) is accomplished using a cruciform connection element ( 8 ) or a blocking element ( 16 ) or a securing blocking element ( 18 ) which is perpendicular to the cruciform connection element ( 8 ) or the round connection element ( 12 ) in an adjacent side opening ( 4 ).
