Abstract

A fitting for connecting two structural components, particularly plates, includes a clamping device mounted in the first structural component and an expanding sleeve which can be secured to the second structural component. A bolt is arranged in the expanding sleeve so as to be longitudinally movable by the clamping device for expanding the expanding sleeve using a conical portion of the bolt. The conical portion of the bolt is an approximately cone-shaped projection whose longitudinal axis is laterally offset relative to the longitudinal axis of the bolt.

Description

BRIEF DESCRIPTION OF THE DRAWING

In the drawing:

FIG. 1 is an elevational view of a bolt with a cone-shaped projection as the conical portion;

FIG. 2 is an illustration similar to FIG. 1, shown with a partially cut-off cone-shaped projection;

FIG. 3 is an illustration of another embodiment corresponding to FIG. 2;

FIG. 4 is an illustration which is turned by 90° relative to FIG. 3;

FIG. 5 is a sectional view taken along sectional line V—V of FIG. 4;

FIG. 6 is a perspective view of the bolt according to FIGS. 3 to

5;

FIG. 7 is a view of the bolt, corresponding to FIGS. 3 to

6, shown with an injection-molded expanding sleeve around the bolt; and

FIG. 8 is an illustration of another embodiment corresponding to FIG.

Claims

1. A fitting for connecting two structural components, particularly plates, the fitting comprising a clamping device adapted to be mounted in a first structural component and an expanding sleeve adapted to be secured in a second structural component, a bolt being mounted in the expanding sleeve so as to be longitudinally displaceable by the clamping device, the bolt having a longitudinal axis and a conical portion for expanding the expanding sleeve, wherein the conical portion of the bolt is comprised of an approximately cone-shaped projection having a longitudinal axis, wherein the bolt has a radius, and wherein the longitudinal axis of the cone-shaped projection extends at a distance from the longitudinal axis of the bolt which is equal to the radius of the bolt.

2. The fitting according to claim 1, wherein the longitudinal axis of the bolt and the longitudinal axis of the cone-shaped projection extend parallel to each other.

3. The fitting according to claim 1, wherein the cone-shaped projection has at least partially cut-off portions defining cut surfaces, wherein the cut surfaces extend parallel to the longitudinal axis of the bolt.

4. The fitting according to claim 1, wherein the cone-shaped projection has one or more laterally projecting webs having surfaces, wherein the surfaces of the webs extend in alignment with a conical surface of the cone-shaped projection.

5. The fitting according to claim 1, wherein the bolt has a head, further comprising at least one longitudinal rib extending on the bolt shaft between the head of the bolt and the cone-shaped projection and extending parallel to the longitudinal axis of the bolt.

6. The fitting according to claim 5, wherein at least one of the ribs extends beyond an outer circumference of the cone-shaped projection and into an outwardly open slot of the expanding sleeve.

7. The fitting according to claim 1, wherein the expanding sleeve is an injection molded component around the bolt.

8. The fitting according to claim 1, comprising a plurality of cone-shaped projections arranged next to one another on a circumference of the bolt.
