摘要： An expansion dowel is formed of an axially elongated expansion member and an expansion element insertable into a bore through the expansion member. The expansion member has two axially extending first slots located diametrically opposite one another and open at one end of the member. Two axially extending second slots are located in the expansion member offset circumferentially by 90.degree. from the first slots. The second slots are closed at their opposite ends. The first and second slots partially overlap in the axial direction, so that the expansion member is radially expandable in the overlapping region of the slots, while the expansion element is prevented from moving off center during the expanding operation.

摘要： An expansion dowel assembly consists of an axially extending sleeve and a spreading element. Tongues are pivotally displaceably connected to the sleeve and are located one after the other along the axial direction of the sleeve. The tongues are split in the axial directions and can be pivoted inwardly and outwardly relative to the sleeve. Lugs are formed on the radially inner surface of the tongues and project axially beyond one end of the tongues. The lugs afford axial support for the tongues pivoted outwardly relative to the outside surface of the sleeve. The spreading element holds the tongues in the outwardly pivoted condition so that the tongues provide a mechanical lock for the sleeve within a hollow space within a structural member.

摘要： An expansion dowel is formed of an axially elongated sleeve with expansion tongues connected to it so that they can be pivoted radially outwardly projecting from the outside surface of the sleeve. Each of the tongues has a radially directed projection in the unexpanded position with the projection having a dimension transverse to the axial direction of the sleeve greater than the sleeve thickness. To provide an anchoring effect, the tongues can be displaced radially outwardly from the sleeve by an expanding member movable through the borehole formed by the sleeve. In the radially outwardly pivoted position the tongues interlock. Webs connected to the tongues provide an articulated connection between the tongue and the sleeve. The pivot axis formed by the webs extend normal to the axis of the sleeve.
