    Description


    [0001] The present invention relates to a section member system or assembly, which has been specifical­ly designed for making inner doors.

    [0002] As is known, a very important problem to be solved in making inner doors by using extruded section members, for example aluminium section members, is that of properly fitting the section members to walls having different thicknesses to which the doors must be applied; in fact, it is at present necessary to make a very broad range of section member sizes, adapted to be fitted to different applications.

    [0003] Another drawback is that known section mem­bers have weak regions at the zones thereof where there are applied the movable wing supporting hinges, since the stresses due to the cantilever supported weight can cause deformations of the section members.

    SUMMARY OF THE INVENTION



    [0004] Accordingly, the aim of the present invent­ion is to overcome the above mentioned drawbacks, by providing a section member system or assembly, which has been specifically designed for making inner doors, which is adapted for fitting with a very reduced num­ber of component elements, to walls of different thicknesses, while providing a very precise assembl­ ing.

    [0005] Within the scope of the above mentioned aim, a main object of the present invention is to provide a section member assembly the section mem­bers of which have a very great mechanical resist­ance against the stresses generated by the hinges, without causing any types of deformations.

    [0006] Yet another object of the present invent­ion is to provide such a section member system or assembly, the section members of which have a very high finishing degree and comprise perfectly round­ed surfaces and which, in addition to increasing the mechanical resistance of the section members, further contributes to aesthetically improving tne finished door or window frame.

    [0007] 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 materials and which, moreover, are competitive from a mere economic standpoint.

    [0008] 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 or assembly, particularly designed for making inner doors, characterized in that said sec­tion member system comprises a first section member, forming the inner half of the fixed frame, provided with a box-like portion, at the attachement region of the hinges for coupling the movable wing and a housing, for telescopically coupling a second sec­tion member, forming the outer half of the fixed frame, said first and second section members of the fixed frame being adapted to be fitted to walls having different thicknesses,there being moreover provided a movable frame section member which can be assembled by brackets and is provided with fins for restrain­ing the door closure panel.

    BRIEF DESCRIPTION OF THE DRAWINGS



    [0009] Further characteristics and advantages of the present invention will become more apparent from the following disclosure of a preferred, though not exclusive, embodiment thereof, which is illustrated, by way of an indicative but not limitative example, in the accompanying drawings, where:

    Figure 1 shows the first section member forming the inner half of the door fixed frame;

    Figure 2 shows the second section member forming the outer half of the door fixed frame;

    Figure 3 shows the section member forming the door movable wing;

    Figure 4 shows a covering section member;

    Figure 5 is a schematic view showing a door made by using the section member illustrated in the preceding figures; and

    Figure 6 shows a cross sectional view taken along the section line VI-VI of figure 5.


    DESCRIPTION OF THE PREFERRED EMBODIMENT



    [0010] With reference to the figures of the ac­companying drawings, the section member system or assembly, which has been specifically designed for making inner doors, according to the invention, com­prises a first section member, forming the inner half of the door fixed frame, indicated overally at the reference number 1, which is provided, at its inward facing surface, with a box-like body which, at the exposed surface thereof, is provided with rounded corners 3.

    [0011] On said box-like portion there is applied a hinge 4 for coupling the door movable wing or panel, indicated overally at the reference number 5.

    [0012] On the portion of the box-like region facing the wall 6 there are provided opposite fins or legs 7, to which there can be applied a conventional tight­ ness gasket.

    [0013] Perpendicularly to the box-like region a rectilinear portion 10 extends which is provided with opposite fins 11 for applying fittings and the like and which ends with an adjoining arm 13 compris­ing a housing for telescopically coupling a second section member, forming the outer half of the door fixed frame, and indicated overally at the reference number 20.

    [0014] The second section member of the fixed frame 20 has an angular cross sectional shape pro­vided with radiused corners and an end 22 having opposite fins or legs 23 adapted for receiving a tightness gasket for coupling to the fixed wall 6.

    [0015] At the other end portion thereof, the second section member 20 is provided with a rectilinear arm 25 which ends with a right angle bent portion 26 sup­porting an engaging body 27 comprising a housing 28 for receiving the section member coupling screws

    [0016] The engaging body 27 is moreover provided with a pair of lugs 29 affording a precise engaging in the seat or housing 14 formed on the door fixed frame first section member.

    [0017] Thus, the first and second section members can be applied with a given range of possible dis­ placement thereby easily fitting to walls having different thicknesses.

    [0018] Moreover, the second section member 20 of the fixed frame can be made with different sizes so as to fit all of the possible sizes of the wall.

    [0019] As stated, to the door fixed frame, a movable wing or panel can be applied, which has been overally indicated at the reference number 5, made starting from a section member, indicated at 30, which has a rectangular cross-sectional shape, pro­vided with a lug 31 projecting toward an end and adapted to operate as an outer flush or level line for the door wing or panel.

    [0020] On the edge portion opposite to the lug 31 there are provided opposite fins or legs 32 forming a housing for restraining the door panels 33 provided for forming the door panelling assembly.

    [0021] The movable wing forming section members are coupled to one another by means of bracket mem­bers, at the corners thereof, and are provided with rounded off projecting regions, thereby further im­proving the stiffness of the section members.

    [0022] The section member system further comprises a covering section member, overally indicated at the reference number 40, which is provided with a plate like body having, at the end portions thereof, an engaging tooth member 41 and a resting right angle bent foot member 42 for snap applying the section member inside a right angle region formed on the outside of the door fixed frame first section mem­ber, so as to operate as a covering element, as well as screws for mutually coupling the first and second section members of the door fixed frame, and screw coupling means for coupling the first section member of the door fixed frame with respect to a wall or fixed structure.

    [0023] The disclosed section member can be coup­led in a very quick and simple way, and, moreover, the coupled section member system has a great mecha­nical resistance mainly due to the fact that, at the corner regions,there are provided curved zones adapt­ed to stiffen said section members, in addition to improving the aesthetic features thereof.

    [0024] Another important aspect of the invention is that the door fixed frame first and second sec­tion members are so coupled to one another that they can mutually slide.

    [0025] While the invention has been disclosed and illustrated with reference to a preferred embodiment thereof, it should be apparent that it is susceptible to several modifications and variations, all of which will come within the scope and spirit of the invention, as defined in the accompanying claims.
