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 such that it is radially resilient, wherein the dowel sleeve and the dowel core are 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 core and the dowel sleeve each include two inclined inner or outer annular sidewall surfaces, respectively, that are offset in the axial direction, wherein the dowel sleeve and the dowel core are configured such that the inclined surfaces of the dowel core contact the inclined surfaces 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 at two axially offset locations.
