Arrangement of Structural Components That Are Moveable Relative to One Another and Assume a Defined Stable Position by Means of a Locking Device in at Least Two Relative Positions

Abstract

An arrangement of a first structural component and a second structural component that are movable relative to one another and assume a defined stable position in at least two relative positions to one another has a locking device with at least two locking recesses and at least one locking nose interacting with the at least two locking recesses. The locking recesses are provided on the first structural component and the at least one locking nose is provided on the second structural component. The locking device provides securing forces of different magnitude for unlocking the at least one locking nose depending on a direction of relative movement of the first and second structural components relative to one another.

       8 . The arrangement according to  claim 1 , wherein the at least one locking nose and the at least two locking recesses have a trapezoidal cross-sectional shape.  
   
   
       9 . The arrangement according to  claim 1 , wherein the at least one locking nose or the at least two locking recesses have a trapezoidal cross-sectional shape.  
   
   
       10 . The arrangement according to  claim 1 , wherein the first and second structural components form a swivel joint comprised of a first joint part and a second joint part, wherein the first joint part has a circular recess and wherein the second joint part has a rotary body that is received in the circular recess, and wherein the locking device is provided on a circumferential wall of the rotary body and a circumferential wall of the circular recess.  
   
   
       11 . The arrangement according to  claim 10 , wherein the locking device has three of the at least two locking recesses and three of the at least one locking nose, wherein the three locking recesses and locking noses are staggered at a rotary angle of 120 degrees relative to one another, respectively.  
   
   
       12 . The arrangement according to  claim 10 , wherein the locking device has two locking units each comprised of one of the at least two locking recesses and one of the at least one locking nose, wherein the two locking units are staggered by 180 degrees relative to one another.  
   
   
       13 . The arrangement according to  claim 10 , wherein the rotary body has springy arms and wherein the at least one locking nose is arranged on one of the springy arms, respectively.  
   
   
       14 . The arrangement according to  claim 10 , wherein the rotary body is a separate component and is connected to the second joint part so as to rotate commonly with the second joint part.  
   
   
       15 . The arrangement according to  claim 14 , wherein the rotary body is a ring comprising an inner toothing and wherein the second joint part comprises a ring gear meshing with the inner toothing.  
   
   
       16 . The arrangement according to  claim 12 , wherein the rotary body is a round disk and is connected positively to the second joint part.
