Supporting device having infinitely adjustable jibs
First Claim
1. An adjustable supporting device for securing a jib to a support column, said supporting device comprising a jib connecting device having a clamping chuck with connecting means for connecting said jib to said clamping chuck and a tightening wedge to facilitate supporting engagement of said connecting device and said column;
- said clamping chuck surrounding said column on three sides thereof for laterally placing said jib on said column and removing said jib therefrom, wherein said clamping chuck comprises;
a supporting wall, to which said jib is removably connected, extending over the width of a first side of said column, said supporting wall having a guide web which forms part of a centering means for said clamping chuck along said column;
a clamping plate connected to said supporting wall and extending over the width of a second side of said column adjacent to said first side of said column;
a U-shaped tightening wedge cage having a first side wall connected to said clamping plate and a second side wall which limits a passage opening in front of a fourth side portion of said column, which passage opening extends to said guide web on said supporting wall, wherein the opening of said U-shaped cage faces a third side of said column, opposite the first side of said column, for receiving said tightening wedge which is supported between said clamping chuck and a base of said cage, converging in the load direction of said jib.

Abstract
The supporting device comprises a support column (1), on which a jib-wedge connecting device (2) can be attached in longitudinally displaceable manner and can be locked at any location of its longitudinal extension. The connecting device (2) with a clamping chuck (3), consisting of a supporting wall (3.1), receiving the jib arm (7), a tightening wedge cage (5) and a clamping plate (3.2) which connects these two components, grips around the support column (1) in the manner of a C-shaped engagement element. Frictional engagement is made between the connecting device (2) and the support column (1) by a tightening wedge (4) which is guided in longitudinally displaceable manner in the tightening wedge cage (5).
The clamping chuck (3) is provided with a lateral passage opening (9), through which the clamping chuck, by being placed laterally onto the support column (1), can be engaged with and disengaged from the latter.
