Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a corner coupling member or a T-shaped coupling member and a corner coupling member that is displaced in the longitudinal axis of the leg of the corner coupling member or in the longitudinal axis of the T-shaped coupling member. The present invention relates to a corner or T-shaped joining structure of two molded parts, having a molded part with a half-open chamber and a fixing element for fixing the molded part relative to the coupling part.

Corner or T-shaped connections of two shaped parts made of light metal are known, in which case the shaped parts are joined by welding. This requires expensive welding equipment. When making corner or butt joints to produce frames for windows or doors, welding machines can only be used with advantage in mass production. Furthermore, due to the temperatures generated by welding, microstructural changes of the light metal occur in the butt area, which microstructural changes lead to color differences after the frame has oxidized.

When manufacturing windows or doors without mass production, in which welding machines are advantageously used, corner connections or T-connections are advantageously used to produce shaped parts with corners or butts. A mechanical connection is performed. It is also known to connect the molded parts via screws, expansion parts or by means of groove-like deformations of the molded parts.

An object of the invention is that during assembly, it is only necessary to manipulate the fastening element in the area of the molded part using a tool, without having to carry out drilling, punching and milling operations in the molded part. Corner joint structures of the type mentioned at the outset, which not only make it possible to close the joint seam between the molded parts, but also to allow the surfaces of both molded parts to lie in the same plane with each other; An object of the present invention is to provide a T-shaped joint structure.

According to the invention, in order to accommodate the clamping element as a fastening element in the leg of the corner coupling element or in the T-shaped coupling element, the fixing element is arranged relative to the longitudinal axis of the leg or the T-shaped coupling element. A groove is provided extending at right angles to the connecting member, and the clamping member is located completely inside the groove when the molded member is fitted over the connecting member, and the clamping member is inserted into the molded member using a tool. and at least one
The problem was solved by having two edges cut into the hem web.

In an advantageous embodiment of the invention, the leg of the corner coupling element or the T-shaped coupling element has a recess located in the region of the longitudinal axis, which recess extends perpendicularly to the groove. As a result, a tool is introduced into the recess through the opening delimited by the edge web of the chamber, by means of which the edge of the clamping member is moved out of the groove of the connecting member. In this case the edge engages in the edge web of the half-open chamber. The clamping element is guided in the groove in such a way that it exerts a force on the associated molding element that has a component acting in the direction towards the connecting seam. The force component forces the forming element cooperating with the clamping element in the direction towards the connecting seam and causes the connecting seam to close. Another force component acting on the edge web of the half-open chamber of the molded parts not only causes the edges of the clamping member to bite into the edge web, but also serves to adjust the faces of the molded parts to be joined flush with each other. This ensures that no lateral displacement of the molded part occurs in the area of the connecting seam.

Molded parts with half-open chambers are preferably used for frame structures for wood-aluminum windows or doors.

The invention will now be explained with reference to the illustrated embodiment.
