<p>A plastics push button (6) for fastening an article such as trim strip (11) or body panel to a motor body using weld studs (14) attached to the surface of the motor body comprises a large circular retaining head (8) at one end of a short, hollow cylindrical stem (7) and a circular skirt (9) at or near the other end of the stem, the diameter of the skirt (9) being substantially equal to the diameter of mounting holes (10) provided around a panel or at intervals along the length of a trim strip (11) and the diameter of the head (8) being greater than that of mounting holes (10), the skirt (9) being provided with a plurality of protruding, resilient fringe members (12) which can lightly engage the rim of a mounting hole (10) and the bore (20) of the cylindrical stem (7) being provided with resilient fingers (18) which can engage the projections (21) of a weld stud (14) when the push button (6) is pressed through a mounting hole (10) so that the cylindrical head (8) abuts the top surface of the article (16) and the cylindrical stem (7) passes through the mounting hole (10) and is pressed over the weld stud (14) so that the article is thereby retained on the surface of the sheet (15) to which the stud (14) is welded. For some applications, such as the application of body panels, the skirt (9) may be provided at the end of the stem (7) remote from the retaining head (8) but for other applications the skirt (9) may be provided on the stem (7) a short distance from that end. <IMAGE></p> |
