<p>The adjustable spacer is used for the attachment of two plate-shaped components (18 and 25) at a variable spacing and consists essentially of a plastic anchoring part with a hollow shaft (14) having an internal thread, which anchoring part can be inserted into a mounting hole in the one component (18), and consists of a spacer screw which can be screwed into the shaft (14) and has a supporting head (3). …<??>In order to be able to screw the component (25) resting on the spacer screw onto the supporting head (3), after precisely adjusting the said spacer screw, without the screw rotating at the same time in the hollow shaft (14), the spacer screw has a multiply slotted, dowel-like expansion part, underneath the threaded shank (4), with a penetrating hole (5) in the threaded shank (4) and a narrowed penetrating hole, connecting thereto, in the expansion part for a woodscrew (13) to be screwed in. In addition provided on the external envelope of the dowel segments (8) formed by the longitudinal slots there are also ribs, running parallel to the axis, while the hollow shaft (14) of the anchoring part is provided underneath the internal thread with grooves running parallel to the axis into which the ribs engage in a positively locking manner when the dowel segments (8) are spread apart by the screw (13) being screwed in. …<IMAGE>… </p> |
