Description: The present invention relates to a section member system for making window and door frames having a sliding guide for a roller blind. As is known, for making window and door frames in general, such as frames for doors, door-windows, windows, inner wings, blinds, it is at present necessary to use a lot of different section members in order to fit all of the requirements of the users. Another drawback is that, in order to obtain the desired mechanical resistance of the window or door frames, it is necessary to use section members having comparatively large cross-sections, which require a lot of expensive constructional material. Another drawback is that the assembling procedure of the several section members is very difficult and frequently requires that highly skilled operators be used. The document EP-A-0 128 259 discloses a section member assembly having substantially the features of the preamble of the main claim. The document US-A-2 984 299 discloses a section member assembly in which for sliding therein the blind is not defined in a section member but is obtained by laterally adjoining two section members which must be individually affixed to the two side uprights of the window or door frame. The document W0-A-8 402 736 discloses a section member assembly which comprises an upright section member having a sliding guide for a roller blind There are also provided modular section members for making the roller blind covering box member. Accordingly, the aim of the present invention is to overcome the above mentioned drawbacks by providing a section member system, for making window and door frames in general, which affords the possibility of making window and door frames with good technical and aesthetic characteristics, while using comparatively reduced size and economic section members. Within the scope of the above mentioned aim, a main object of the present invention is to provide such a section member system which affords the possibility of fully eliminating the relief abutment arrangements so as to provide actually flat window and door frame surfaces. Another object of the present invention is that of providing such a section member system or assembly which affords the possibility of easily making single-block window and door frames and in which the single section members are already provided with guides for roller blinds as well as for the box element covering the roller blind cylinder. Yet another object of the present invention is to provide such a section member system the section members of which can be easily made starting from easily available elements and materials and which, moreover, is very competitive from a mere economic standpoint. According to one aspect of the present invention, the above mentioned aim and objects, as well as yet other objects, which will become more apparent hereinafter, are achieved by a section member system for making window and door frames in general, having the features of the characterizing portion of the main claim.
