Corner connector for door or window frame - has welding surface running on mitring and shaft evolving from welding surface and matching inner cross=section of hollow profiles to be joined

摘要

The shaft is inclined on one side surface on which a tension wedge is displaceable. The rise of the inclined side surface is directed crossways to the longitudinal direction of the shaft and the tension wedge is displaceably arranged on the surface crossways to the shaft. A drive wedge is provided which is insertable in a guide channel via the welding surface in the longitudinal direction of the shaft. The guide channel is limited on one side by a back surface of the tension wedge working in conjunction with the drive wedge. The back surface of the tension wedge is inclined to correspond with the wedge surface of the drive wedge. USE/ADVANTAGE - A corner binder for hollow profile window or door frames which can be simply, rapidly and firmly tensioned in the hollow profile and is cheap to produce.
