Frame for an Input and Output Device and Method for Manufacturing the Frame

A method for manufacturing a frame for an input and output device, a frame profile being utilized which including a first leg and a second leg, a strip being arranged on the first leg and a groove being arranged on the second leg, the method comprising:

• cutting a length, which corresponds to a subsequent circumference of the frame, by a frame profile;
• introducing open spaces into the frame profile in accordance with subsequent side lengths of the frame to form four corners such that the strip stands in a region of cutouts resulting from the introduced open spaces, a size of the introduced open spaces being established such that an overbending required in a subsequent step occurs without interference;
• bending the four corners at points of the introduced open spaces, sides adjoining a respective corner being respectively overbent beyond an angle of 90° to overcome a residual material stress and to prevent the sides from springing back to an original position;
• arranging a respective corner element in each respective corner of the four corners, the corner element including an element body having a first element leg and a second element leg, the first and second element legs being arranged substantially at right angles to one another on the element body and respective corner elements being arranged in the open spaces such that the first element leg and the second element leg are each arranged in the groove of the frame profile;
• and
• welding together a remaining impact face after said arranging respective corner elements in respective corners of the four corners.
