<p>FIW2462 21.01.2011LDAbstract5Fixing elementThe invention relates to a fixing element (1) for anchoring in a drilled hole, having a shank portion (2) and an expansion element (3), there being arranged on the shank10 portion (2) an expander body (8) for expanding the expansion element (3). The expansion element (3) has a plurality of arcuate expansion lobes (11), each expansion lobe (11) being formed by two bridging portions (14) connected by a yoke (15). The bridging portions (14) of the expansion lobes (11) together generate an envelope surface (M) of the expansion element (3), which envelope surface (M) has rotational15 symmetry about the longitudingal axis (A) of the fixing element (1). In order to provide a fixing element (1) which can be used both in a wide and also in a narrow drilled hole, the invention proposes that the yoke (15) have an arcuate curvature (17) which projects beyond the envelope surface (M) in the radial direction (R).20 (Figure 2)</p> |
