<p>A device for mounting door frames, window frames and similar objects (1) at an adjustable distance from a support structure (2) has a tubular member (3) insertable into a through hole in the supported object (1), a screw means (7) insertable into a hole (6) extending longitudinally through the tubular member (3), the tubular member (3) also including adjacent to a first end portion a restricting surface spaced from a resilient locking means (9), arranged to facilitate axial displacement of the screw head into a contact position with the restricting surface, but preventing withdrawal from this contact position. The second end portion of the tubular member (3) is arranged to form a preferably substantially disc-shaped abutment member (4), restricting the insertable distance of the tubular member (3) into the supported object (1). A portion of the tubular member (3), located adjacent to the abutment member (4), is arranged with means (9) for engagement with the internal surface of the surrounding hole in the supported object (1), said means (9) preferably comprising a screw thread or similar, arranged to be diametrically expanded into said engagement by insertion of the screw (7) into the hole (6) of the tubular member (3).</p> |
