The frame is made up from several die-cast plastics sections (1,2) which have integral handles (3). The joints of the sections consist of overlapping ends which are secured together. One joint end can be in the form of a handle, so that the handles are located at the points where the sections are joined. The mating overlapping ends are recessed so the sections fit flush together. The overlapping joint sections have holes which line up with one another and which are used for fixing elements. |
