This invention relates to improvements in the manufacture of thin panels, of large area, in one piece or in several assembled elements. These panels or panel elements can be obtained by 5 means of any suitable processes and particularly by fianging, pressing, stamping, rolling or other similar processes, and even, in certain cases, they can be totally or partially obtained by casting- These improvements are mainly characterized by the following points applied separately or in combinations:
(a) the thin panel has resistant portions of suitable shape, or of progressively varying thickness which constitute ribs preferably closed on 151 themselves and providing between them suitable cavities.
(b) the thin panel is preferably transversely corrugated, or is constituted by continuous ele ments variously set.
(0) the closed resistant ribs are constituted by cut out strips or elements.
(d) the thin panel is constituted by curved or plane surfaces alternately displaced in surface and in projection, so as to form girder head plate elements, and connected by transverse walls which form web elements connecting the head plates.
(e) the glass framing posts or the filling up panel posts, in case the panel is a carriage door, provide for the displacement of the bearing plane of the glass plate, in order that the said bearing plane should usefully participate in the rigidity and resistance of the whole structure, as element of head plates of the girder section of the post.
(1) the curved or plane surfaces displaced for forming head plates, totally or partially form the thin panel and preferably form extensions of the resistant elements or sole members provided on the panel and particularly on the posts or standards, if the latter exist.
(g) the thin panel is constituted by surfaces variously set or corrugated, the intersection ridges of which or the lines of apices of which constitute the elements of the girder head plates and preferably form extensions of the resistant elements or sole members provided on the panel and particularly on the posts or uprights.
(h) the filling up panels, or the various constituent elements of a panel, are assembled by means of screws, bolts, rivets or other suitable means, with interposition of sleeves, rings or washers, made of a resiliently distortable material.
A form of construction of a one-piece carriage 55' door, more particularly described subsequently,
by Way of example only, is mainly characterized in that the portions of progressively variable thicknesses are constituted by pyramidsor truncated cones, the central portions of'whichpres'e'nt cavities, preferably in the shape ofa pyramid or 0 of a cone, truncated'or not.
The flanges of a swing panel, such as a carriage door, can be constituted, for one or'twoadjacent flanges and in order to fit intoexisting doorcases, by surfaces parallel tO'lZIlB corresponding door-case and whichform witli the general or local adjacent surface of the panel, angles which are inferior or equal to 90, or more generally inferior or equal to 90 plus the stripping slope.
The re-entering or insufiiciently cleared angles of a swing panel, presenting the above-mentioned particularities, can be actually cast by utilizing suitable cores and ordinary flasks or casting boxes.
The invention also relates to a swing panel such as a one-piece carriage door presenting the preceding particularities and which is obtained, by casting, Without utilizing cores in the re-entering or insufficiently cleared angles, that is to say those which are inferior or equal to 90.
The invention also relates to the casting process to obtain a panel such as previously defined and which is mainly characterized in that the stripping joint surface is arranged obliquely relatively to the direction of removal from the mould.
Such frames can be obtained according to numerous forms of execution which are obviously all included in the scope of the present invention and some of which are subsequently described.
The element of dissymrrietry introduced by the stripping obliquity is utilized for internally recessing the wall opposite to that presenting the previously mentioned particularities.
The accompanying drawings illustrate by way of example, improved carriage doors and panels 5 in accordance with the invention.

Figure 14 is a section Fig. 9.
The one-piece car door illustrated, by way of example only in Figs. 1 to 9 inclusive, is constituted by a panel composed of several corrugated or variously set elements 1. The corrugations are preferably disposed transversely of the panel, so as to constitute a girder-panel and to cause the entire material to efficiently contribute to the resistance of the entire structure.
The parts of progressively variable thickness are constituted, in this case, by truncated pyramids 2, the central region of which is provided with recess 2 having preferably the shape of a pyramid, truncated or not. I
Figs. 9 to 14 illustrate a form of construction of a swinging car door, the upper flange 3 and the vertical flange 4 bearing the hinges and binge bands of the said door being perpendicular to the general surface of the door. 7
Such a one-piece door can be obtained by caston line XIVXIV of ing without the intermediary of cores, owing to the casting process previously characterized.
The stripping direction or direction of removal from the mould is substantially placed in the bisecting plane 10 of the stripping slopes of each of the flanges 11 and 12 of the door answering to the angle conditions previously mentioned.
The stripping direction is therefore determined by the intersection of two bisecting planes.
This inclination is used, moreover, for internally recessing and lightening the opposite flanges, and in particular at 13 the flange opposed to the hinge and which must present an accentuated slope 14 in order to facilitate the opening of the door.
The arrangements previously indicated avoid the utilization of inner cores.
It is obvious that the forms of construction described and illustrated are only simple examples capable of receiving modifications, as Well in the constitution of the various elements as in the relative arrangement of the latter. All modifications which do not alter in any way the main features above set forth, or the object sought for, are included in the scope of the present invention.
What I claim as my invention and desire to secure by Letters Patent is;
A door formed from a single piece of thin metal and having reinforcing ribs, which form truncated pyramids whose central portions have cavities in the form of pyramids so that the successive sections increase from center toward the exterior in the region of the said pyramidal cavities, then decrease from the said cavities toward the periph cry of the door.
