The invention relates to a bracket comprising four mitre-cut profiles forming the lateral sides and cross-pieces of each sliding or non-sliding frame for a leaf intended for an opening. The two sides of a bracket are introduced into the ends of the profiles in order to join same at a right angle, one horizontally in the profile to form the cross-piece and the other vertically to form the lateral side of the frame, until an optimum joint is achieved between the mouldings located on both faces of the bracket and the counter-mouldings of the profile, thereby immobilising the bracket inside the profiles, said profiles being at a ninety degree angle. Once the joint has been formed, it is secured by means of a pair of stainless steel self-tapping screws that pass through two threaded holes located in the internal structure itself of the bracket. |
