摘要

An expansible dowel is formed from two cylindrical half shells made of plastics, and with the two halves joined to each other by a flexible hinge at the inner end of the dowel. In this addition to the patent, the upper half shell (2a) of the dowel (1), when the dowel is in its installed position, has an internal profile in the form of a screw thread. The lower half (2b) has a U-shaped cross-section and receives a metal U-shaped section (10) which is open on the upper side. This type of expansible dowel is especially suited for supporting objects held at a distance from the supporting wall. USE - Expansible dowels.
