Connecting device for two workpieces, particularly for bar-type hollow profiled members

摘要

A connecting device joins a first workpiece that is provided with an interior space, particularly a bar-type hollow profiled member, to another such workpiece by a screw or similar element, the shank of which penetrates an opening of the workpiece and can be inserted into an opposite element within the interior space. The shank of the clamping screw penetrates a sleeve of the connecting device, which is fixed within a longitudinal groove of one workpiece such that a threaded area of the clamping screw protrudes beyond the face of the workpiece and is provided with a screw head at a distance therefrom. The screw head is able to be inserted into an undercut longitudinal groove of the other workpiece. The sleeve is removably fastened within the longitudinal groove of the workpiece and is connected thereto by a groove/spring system that runs perpendicular to the longitudinal axis (A) thereof.

主权项

1. A connecting device for connecting a first workpiece having an interior space to a second workpiece, said connecting device comprising:
a clamping screw and a sleeve; the clamping screw having a shank which engages in a longitudinal groove of the first workpiece and which can be inserted into an opposing element in an interior space of the second workpiece; the shank of the clamping screw passing through the sleeve; said sleeve being provided with outer ribs and being fixed in the longitudinal groove of the first workpiece such that a threaded area of the clamping screw protrudes beyond a face of the first workpiece; said clamping screw being provided with a screw head; the threaded area of the clamping screw having a nut screw head which can be fitted thereon; said nut screw head being designed such that said nut screw head can be inserted into an undercut longitudinal groove of the second workpiece; the sleeve having at least three groups of said outer ribs which are parallel to a longitudinal axis of the sleeve; said outer ribs, in a fixing position, being assigned to radial grooves in a groove bottom and in facing surfaces of the longitudinal groove; and wherein one of said outer ribs is approximately triangular in cross section and merges with its rib faces into shaped channels of a sleeve outer face.
