figure 4 is a depiction of enlarged parts of fittings to be fastened to the wall for equipping it;
figure 5 is a prespective view, partially broken away, of a frame for equipped wall, having double face, or central wall, also according to the present invention;
figure 5a depicts a fitting to head-finish the equipped wall according to figure 5, if desired;
figure 6 is a partial view in cross-section of the free end of a central wall using the frame of figure 5;
figure 7 is a complete perspective view of the same central wall resting against the back of a simple face equipped wall.

Referring first to figures 1 and 2, it is seen that a frame 10 for an equipped wall structure according to the invention consits of two uprights 12 and 14, having "L" shape, each other connected by crossbars 16a-e, having "T" shape, joined to the uprights 12 and 14 by per se kown means, such for example bolts and nuts 18, 20 and 22, 24 (see figure 2).
As it is particularly well seen in figure 1 for the crossbar 16b, said crossbars have "T" shape with a head 26 and a leg or rib 28, at least the rib 28 showing a polished and inalterable finish, such as an external chromium-plating layer. Further, through the rib 28 are pierced regular openings 30, for example square openings, having the purpose of fastening fittings which cooperate for the equipment of the wall.
According to the requirements of the equipped wall to be prepared, a square defined between the two uprights 12 and 14 and two adjacent crossbars, for example 16b and 16c, can be left either empty or filled with a board 32 which can be of different materials, such as raw wood, polished, painted or coated wood, plastic materials, plaster and the like, so sized to be exactly inserted in the squares defined by the two uprights and the adjacent crossbars. The board 32 is provided with means providing a fast clamping to the metal portions of the frame 10, which conveniently is made of iron, said means consisting for example, even if not limitedly, of permanent magnets 34a-c, having substantial shape of coins, housed in proper rear recesses 36a-c and faced against the head 26 of the crossbras 16a-e. Although it is not obviously possible to be limited to permanent magnets as fastening means of the boards 32, the choose of permanent magnets is particularly preferred because allows fast assemblies and disassemblies of said boards without using any special tool.
Referring to figures 3 and 4, it is seen that a simple face equipped wall 40 comprises a plurality of rectangular boards 32a-d having along their orizontal sides protruding ribs 28a-e, corresponding to the ribs 28 of the crossbars 16a-e. Said ribs 28a-e are provided with rows of regular openings 30 suited to house fingers or hooks of means to be insertion fastened to said ribs. An example of said means consists of so called racks 42 and 44 formed by rectangular pipes 46 and 48 provided, on a rear face, with fingers or hooks 50a-d and 52a-d suitable to be inserted into the above mentioned openings 30 and, on a front face 54 and 56, with vertical window or slits 58 and 60 suited to engage portions of fittings to be connected to said racks 42 and 44.
A particular fitting to be fastened to said racks 42 and 44 are some brackets 62 and 64 embracing with an internal enlarged portion 66 thereof (figure 4) the pipes 46 and 48, making enter their tangs, such as the tang 68 depicted in figure 4 , into one or more of the windows or slits 58 of the racks. The brackets 62 and 64 are fastened to the racks 42 and 44, resisting to bending moments thereto applied without allowing the exit of their tangs 68 from the windows 58, while a traction provided along an axial direction according to an arrow 69 allows an easy removal of the brackets themselves from the racks 42 and 44.
These brackets are fore terminated by a thinned portion 70 provided with a vertical slit 72 connecting the upper and lower faces thereof or, alternatively, with a slit 72a connecting lateral faces thereof.
The brackets 62 and 64 can provide many and different support tasks, for example, for a support plane 74 in the form of a table of wood or equivalent materials or for coupling fittings, such as the so called hangers herebelow discussed.
Referring first to figure 4, it is seen that the slits 72 can house flat wedge members 76 provided with a vertical slit 78 which, when inserted protrude under the bracket for engaging a bar 80 or 82, called "hanger" of simple kind 80, or of telescoping kind 82 with an end provided with support members 84 to allow the hanging of further articles to be exibited.
The insertion of the hangers 80 or 82 can occur according to two alternative ways:

a) two wedge members 76 are inserted into the slits 72 of the thinned portions 70 of the brackets, making descend them till their slits 78 appear completely free under the brackets themselves and then one of the bars 80 or 82 is inserted into the slits 78 of the members 76;
b) one of the bars 80 or 82 is directly inserted into the slits 72a alternatively provided in the thinned portions 70 themselves.

The bars or hangers 80 or 82 have at their ends notchs 86 and 88 in the upper and lower edges, respectively, to allow the fastening of the hangers to the members 76 and housing some kind of clamp to prevent accidental slipping of the hangers themselves.
Reference is now made to the alternative embodiment depicted in the figures 5 to 7 for an equipped double face or central wall, having boards and ribs provided with engaging openings on both opposed faces.
For said central wall is provided a frame 110 formed by two uprights 112 and 114 having "T" shape each other connected by cross bar pairs 116a-c and 117a-c, having "T" shape, connected to the uprights 112 and 114 by per se well known means, as for example screws or bolts 118 (figure 6).
As it is particularly well seen in figure 5, for the crossbars 116b and 117b, said crossbars have T shape with heads 126 and 127 and legs or ribs 128, 129, where at least the legs 128 and 129 have a polished and inalterable finish, such as an external chromium-plating layer. Further, through the legs 128 and 129 are pierced regular openings 130 and 131, for example square openings, having the purpose to fasten fittings cooperating to the equipment of the wall.
According to the requirements of the equipped wall to be prepared, a square defined between the two uprights 112 and 114 and two adjacent crossbars, for example 116b and 116c, or 117b and 117c, can be left empty or filled by boards 132 and 133 which can be of different materials, such as raw wood, polished, painted or coated wood, plastic materials, plaster and the like, so sized to be exactly inserted in the squares defined by the two uprights and the adjacent crossbars. The boards 132 and 133 are provided with means allowing them a fast clamping to the metal portions of the frame 110, which convenientely is made of iron, said means consisting for example, even if not limitedly, of permanent magnets 134 and 135, having substantial shape of a coin, housed in rear suitable recesses 136 and 137 and faced against the head 126 of the crossbars 116a-c. Although it is not obviously possible to be limited to permanent magnets as fastening means of the boards 132, the choose of permanent magnets is particularly preferred because allows fast assemblies and disassemblies of said boards without using any special tool.
For the complete finishing of a central wall, in order to house equipments to be hung on both the two faces and the free end, is used a fitting depicted in figure 5a, allowing to finish the head of the wall for having the same appearance of the lateral faces. This fitting is formed by a profiled member 116' comprising a head 126' and a leg 131' provided with at least a square opening 130'. This fitting is inserted, as depicted in figure 6, between extensions 128' and 129' of the heads 128 and 129 of crossbars 116 and 117, so that exernally the polished ribs appear substantially each other continuous between the faces of the wall and its free end. The fitting 116' is covered by a coating strip 132' of the same material of the boards 132 and 133 (for example wood) fastened against the head 126' of the fitting 116' by one or more permanent magnets 134' housed in corresponding recesses 136'. The strip 132' is extended by two lateral wings 138' and 139' to assure appearance continuity with respect to the boards 132 and 133.
Of course, the fitting 116' is provided with means for fastening it to the upright 114, for example screws or bolts which cross corresponding holes in the head 126' of the fitting 116' and the upright 114.
Referring to figure 7, it is seen that a central wall 140 according to the present invention comprises a plurality of rectangular boards 132a-e and head strips 132'a-e having along their orizontal sides protruding ribs 128a-f and 131'a-f corresponding to the ribs 128 of the crossbars 116a-c. Said ribs 128a-f and 131'a-f are provided with rows of regular openings 130 and 130' suited to house fingers or hooks of means to be inserted in said ribs. Of course, the ribs 132a-f are extended in corresponding boards on the opposed face of the central wall 140.
It is realized that the wall 40, resting against the central wall 140, can be identical to the equipped wall 40 of figure 3 with a similar kind of ribs 28a-f and similar boards 32a-f. For a stable support thereof, the free end of the wall 140 rests on a foot 150 which, of course, must be deemed connected to the upright 114 of the frame 110 depicted in figure 5.
What has been hereabove disclosed depicts just some embodiments of the present invention not to be intended as limiting the scope thereof which must be apreciated from the enclosed claims.
Those skilled in this art will devise obviously similar and equivalent provisions to be all considered as here covered. For example, the crossbars 16a-e of the frame 10 could be formed by "L" shaped irons instead of the here depicted "T" shaped irons. The crossbars 116a-c and 117a-c of the frame 110 could be replaced by cross shaped irons, even if that can cause some complications in connecting the crossbars to the uprights and in housing the head fittings 116'. At last, a double face equipped wall could also be formed by joining two simple face walls depicted in the figures 1 to 4.
