Abstract
The adjustable stand (1) includes a tubular arm (2); an arm joint (5) by which the tubular arm (2) is pivotally connected to a connection part (22); a spindle (6) in the tubular arm (2) that receives a compression spring (3) with a given pre-tensioning provided by a first spring stop (7) in the form of a washer and by a second spring stop (8). The spindle (6) has an axial extension (9) pivotally connected with the connection part (22) by means of a lever (11) The tubular arm (2) is provided with two opposing indentations (13) having a distance (X) from one another, the washer forming the first spring stop (7) has two opposing first sides (14) closer to each other than the distance (X) between indentations (13) and two opposing second sides (15) arranged rotated 90.degree. to the first sides and further from each other than the distance (X) between indentations (13), so that the washer may pass by the indentations (13) during assembly and rotate 90.degree. to take a bayonet locking position. The washer is formed so that, although the stand is easy to assemble, the washer cannot be easily disengaged from the bayonet locking position, but only deliberately by axially pressing in and r…
