摘要
A supporting device for setting with a large freedom of choice in the space, of a first object, like a computer keyboard is described. It is characterized by the following: a cylindrical body (1, 2), comprising an upper cylindrical part (1) and a lower cylindrical part (2). An upper piston (22) is axially movable in the upper cylindrical part (1) and a lower piston (6) is axially movable in the lower cylindrical part (2). The upper cylindrical part (1) is connected to a hollow body (24, 25), parted into two hollow body parts (24 and 25), with a gap (32) between them. A ball body (27) is grasped by the hollow body (24, 25) and the upper piston (22), and a shaft (26) is fixed to the ball body (27), pointing out through the gap (32), carrying said first object (30). The lower cylindrical part (2) is connected to a house (12, 13), which comprises two body halves (33, 34) each being connected to its pin halve (9, 10), which extend downwards to a fastener (18) in said second object. A wedge element (8) is provided, which can be acted upon by the lower piston (6), and an expander means (20, 21) is provided, which when acted upon by an outer means part, like a handle (21), can either bring the upper piston (22) and the lower piston (6) apart, locking, so that the ball body (27) is locked by the upper piston (22) and the wedge element (8) forces the two body halves (33, 34) apart, locking, so that the pin halves (9, 10) are locked in the fastener (18), or releasably admits, that the upper piston (22) and the lower piston (6) approach each other.
