Abstract:
1. A fastening device for furniture fittings on furniture parts, the device comprising: a radially resilient cylindrical dowel sleeve; a hollow cylindrical dowel core for being arranged inside the dowel sleeve and inserted into a drilled hole of a furniture part; and an actuating device configured to move the dowel sleeve relative to the dowel core, whereby the dowel sleeve is selectively changeable from a relaxed condition to a radially expanded condition, wherein the dowel core has a longitudinal slit in at least substantially an entire length of the dowel core, is made of spring steel, and is constructed such that it is radially resilient, and wherein the dowel sleeve and the dowel core include corresponding engagement surfaces on inner or outer annular sidewall surfaces, respectively, configured such that moving the dowel sleeve relative to the dowel core using the actuating device causes the dowel sleeve to expand on the dowel core, wherein the dowel sleeve and the dowel core are configured such that the engagement surface of the dowel core contacts the engagement surface of the dowel sleeve in the expanded condition and in the relaxed condition, and whereby relative axial movement of the dowel sleeve with respect to the dowel core, and radial resilience of the dowel core, causes a substantially even expansion of the dowel sleeve along the longitudinal extent of the dowel sleeve.
