Description

Hinged piece for forming the corners of drawer frames made of Höh! Profil "

In the furniture industry, there is an increasing number of drawer constructions Entrance found that essentially consists of the three-sided frame, which is mainly made of plastic the respective piece of furniture adapted front misery as the fourth side of the frame and the one covered with plastic film Plywood or chipboard are used as a slide-in floor For reasons of strength, an extrusion-molded PVC material is used for the frame construction Hollow profile preferred, both with reinforcing ribs in the interior and with those for the drawer guide and the required grooves on both sides of the slide-in base walls is provided · A particular problem with this type of construction is the formation of the frame corners Miter cut required for this only up to the inner surface the outer wall so that the remaining outer wall parts serve as a hinge when the 90 ° angle of a corner is formed and also give it a certain hold However, the narrow cut surfaces of the miter cut are not sufficient for a durable gluing of the corner. With help of lining pieces made of wood, pressboard or plastic that are pushed into the cavities of the adjoining frames larger glued areas combined with an increase in corner rigidity can be achieved * However, such measures are material and labor intensive.

The present application relates to a joint made of suitable Material (wood, plastic, composite construction made of Wood or plastic with metal), the height of which corresponds to that of the frame chambers exposed by the miter cut * and its cross-section in the main part of the fora

Fig.1 first shows the corner part of a drawer frame made from a hollow profile with a miter cut in elevation, plan and side elevation. The miter cut at 90 ° only extends to the inner surface of the outer wall and exposes two chambers a ,, and ag, which are intended to accommodate the articulated pieces. the hat b £ to accommodate the slide-in base plate
