Abstract:
A jointed support structure for the adjustable attachment of objects, comprising:at least one clamping jaw element having a clamping member, preferably made as a retaining ball, and a clamping jaw displaceable relatively thereto for the alternate clamping and unclamping of the clamping member; at least one elongate connecting element connected at one end to the clamping element and preferably made as a tube; an actuating block connected to the other end of the connecting element; at least one push rod extending at least substantially parallel to the connecting element and connecting the clamping jaw and the actuating block in a thrust transmitting member; a movement generating device generating a movement extending at least substantially perpendicularly to the push rod; and at least one toggle lever mechanism with a first toggle lever loaded by the movement generating device at one end and connected at its other end to an end of the push rod facing the actuating block in a thrust transmitting manner and transfering the movement generated by the movement generating device to the push rod, whereby the clamping jaw can alternately be brought into and out of clamping engagement with the clamping element, each toggle lever mechanism having a second toggle lever which is connected to the first toggle lever via a toggle lever joint and whose end remote from the toggle lever joint is pivotally supported on the actuating block, and the toggle lever joint of the toggle lever mechanism being moveable in the direction of the movement generated by the movement generating device.
