Abstract

The present invention relates to a ball joint mechanism which is adapted to permit setting of two members relative to each other, said members forming part of a settable device for gas transport, whereby one of said members preferably consists of a gas conduit and the other member preferably of a nozzle which is connected with said gas conduit and settable in various positions in relation thereto. In order to permit, at a ball joint mechanism of this type, quick setting by hand of the spring forces without any operations in the ball joint mechanism itself, said mechanism (11) comprises two pivotally mounted balls (13, 14) of which one ball (13) is connected with one member (6 and/or 9) of the settable device (1) and the other ball (14) with the other member (10) of said settable device, whereby the balls (13, 14) cooperate with friction elements (17, 18 and/or 19, 20) for obtaining the required frictional resistance when said balls pivot, and whereby at least one spring element (21) is provided to compensate for eventual wear of said friction elements (17, 18 and/or 19, 20) and/or of surfaces cooperating therewith of the balls (13, 14); and the balls (13, 14) are provided in a join…
