Cadre rigide p ur baie de forme quadrangulaire Rigid frame for quadrangular bay

La presente invention a pour objet un cadrc rigide pour baie de forme quadrangulaire. Ce cadre est ca racterise par 1e fait quo chaque c6te est constitue par une töle dont los extr@mites sont pliees ä angle droit, Tune des extr@mit@s pdiees de deux cöt6s adjacents kaut situee ä 1'interieur de 1'angle du cadre et 1'autre ä 1'exterleur, et par 1e fait qu'au moins deux de ses cdtes paralleles pre:sentent chacun des Bords replies ä 1'interieur de maniere ä formen des glissieres dans lesquelles s'engage au moins une extremite pliee d'un cöt6 adjacent, 1e tout 6tant maintenu rigidement uni quement par pliage. The present invention relates to a rigid cadrc for bay of quadrangular shape. This frame is characterized by the fact that each side is made up of a sheet whose ends are bent at right angles, one of the ends bent to two adjacent sides kaut located inside the angle of the frame and the other on the outside, and by the fact that at least two of its parallel sides have each of the edges folded inside so as to form slides in which at least one folded end engages on an adjacent side, the whole being held rigidly only by folding.

Le dessin repr6sente, ä titre d'exemple, une forme d'execution du cadre faisant 1'objot de la pr6sente In vention. The drawing represents, by way of example, one form of execution of the frame which is the subject of the present invention.

La fig. 1 est une vue en plan du cadre. fig. 1 is a plan view of the frame.

La fig. 2 est une coupe par la ligne 2-2 de la fig. 1. fig. 2 is a section through line 2-2 of FIG. 1.

La fig. 3 est une vue 6olatee en pers:p-ective ä plus grande echelle d'un detail du cadre. fig. 3 is an enlarged perspective perspective view of a detail of the frame.

La fig. 4 est u:ne vue en perspective dune Partie d'un cadre selo.n une variante. fig. 4 is a perspective view of a Part of a selo.n frame variant.

Le cadre repr6sente aux fig. 1 ä 3 est pr6vu pour une baie de forme rectangufaire et chaque cöte 30, 31, 32 et 33 <B>de</B> ce cadre est constitu.e par ume töle pliee, presentant des extr6mites pliees ä angle droit 34, 35, 34' et 35' respectivement. L'extrem-itd plie:e 34 du cdte 30 est situee ä 1'int6rieur de 1'angle E du cadre, 1'extrem:ite pliee 35 du cöte adjacent 31 6tant situee ä 1'exterieur du cadre. The frame represents in figs. 1 to 3 is provided for a bay of rectangular shape and each side 30, 31, 32 and 33 <B>of</B> this frame is constituted by a bent sheet, having ends bent at right angles 34, 35 , 34' and 35' respectively. The bent end 34 of the side 30 is located inside the corner E of the frame, the bent end 35 of the adjacent side 31 being located outside the frame.

Un des Bords des cC)tes du cadre est plid ä 1'ex tericur en 36 et replie sur lui-meme en 37 de fagon ä formen un rebord p6ripherique plat autour du cadre. L'extKmite Interieure de ce reboird 37 est pliee en 38 par-dessus la Paros Interieure du cadre ou cötes 30, One of the edges of the sides of the frame is folded outwards at 36 and folded back on itself at 37 so as to form a flat peripheral rim around the frame. The inner end of this reboird 37 is folded in 38 over the inner paros of the frame or sides 30,

31, 32 et 33, pour formen une glissiere 39 1e long de chaque cöte. Lautre Bord des c6tes est egalement rDplie en 38' vors 1'int6rieur du cadre pour formen une glissiere 40 sur los c6tes du cadre, analogue ä la g'.issi6re 39. Los deux glissieres 39 et 40 de chacun des cötes paralleles 31 et 33 sont destinees ä recevoir de fagon coulissante une extremite 34 p1iee ä angle drolt du c8,te 30. Los extr6mit6s pü6es 35 et 35' des cöt6s 31 et 33 respeetivement sont engage.es dans los glissiäres 39 et 40 du c6t6 32 dopt los extremites 34' sont pliees ä 1'exterieur des cätes 31 et 33. 31, 32 and 33, to form a slider 39 along each side. The other edge of the sides is also folded at 38' towards the inside of the frame to form a slide 40 on the sides of the frame, similar to the slide 39. The two slides 39 and 40 on each of the parallel sides 31 and 33 are intended to receive in sliding fashion an end 34 bent at a right angle from the side 30. The ends 35 and 35' of the sides 31 and 33 respectively are engaged in the slides 39 and 40 of the side 32 adopt the ends 34 ' are folded on the outside of sides 31 and 33.

Chaque cöt6 du cadre pr6sente, en outre, des Parties saillantes 41 servant ä fixer los angles du re boTd 37. La Partie 41 du cdte 32 vient s'emboiter dans 1e pli corres.pondant de la töle ph6e du c6t6 31 adjacent, et la Partie 41 de ce cöte 31 vieret s'appli quer sous la Partie 41 du c6t6 32 ou vice versu. Pour quo los rebords 37 des cötes 31 et 32 soient dans 1e meine plan, 1e rebomd du c6te 32 est aplati de facon ä ne pas pr6senter d'espace libre entre los deux epais seurs de m6tal comme represente en 42 ä la fig. 3. Each side of the frame also has protruding parts 41 serving to fix the corners of the flange 37. The part 41 of the side 32 fits into the corresponding fold of the sheet metal on the adjacent side Part 41 of this side 31 and apply under Part 41 of side 32 or vice versa. So that the edges 37 of the sides 31 and 32 are in the same plane, the first rebound of the side 32 is flattened so as not to present any free space between the two thicknesses of metal as shown at 42 in FIG. 3.

Le montage du cadre Ecrit se fait de la fa@on suivante 0n assemble tont d'abor .d los cötes 31 et 33 sur 1e c6te 32 en engageant los extremit6s pliees 35 et 35' des c6tes 31 et 33 respectivement Jans los glis sieres 39 et 40 du cdte 32 puis an engage los extre mit6s pliees 34 du c6t6 30 dans los glissieres des cdtes 31 et 33, los,extremit6s 35 et 35' n'6tant pas encore p@liees. Eufin an plie los extr6mites 34' du cöte 32 ä 1'exterieur des cötes 31 :et 33 et los extr6mites 35, 35' ä 1'exterieur du c6t6 30 pour 1e maintenir en place. L'ensemble du cadre decrit-,est ainsi maintenu rigide uniquement par pliage. The assembly of the Ecrit frame is done in the following way: 0n first assembles the sides 31 and 33 on the first side 32 by engaging the folded ends 35 and 35' of the sides 31 and 33 respectively in the slides 39 and 40 of side 32 then an engages the bent ends 34 of side 30 in the slides of sides 31 and 33, the ends 35 and 35' not yet being bent. Finally, bend the ends 34' of side 32 to the outside of sides 31 and 33 and the ends 35, 35' to the outside of side 30 to hold it in place. The whole of the described frame is thus kept rigid only by bending.

Dans la variante nepresentee ä la fig. 4, 1e cadre ne presen:te pas de rebord peripherique plat. Chaque cöte de ce cadre presente comme 1e cbte M des bords replies 43, 44 ä.1'interieur formant des glissieres dann lesquelles est engagee l'extrdmit6 45 pli6e ä angle droit du cöte adjacent N. L'extr6mite 46 du cöt6 M est plie ä angle droit ä 1'ext6rieur du c6t6 N. Le cbte O est montre avec son extremite 46' non encore pliee pour permettre 1'insertion de 1'extr6mit6 pli6e 45 du cöte N Jans les glissieres 43, 44 de ce c6te O. In the variant shown in FIG. 4, the first frame does not have a flat peripheral edge. Each side of this frame has, like the first side M, folded edges 43, 44 inside forming slideways in which the end 45 folded at right angles to the adjacent side N is engaged. The end 46 of the side M is folded at right angles to the outside of the N side. The O side is shown with its end 46' not yet folded to allow the insertion of the folded end 45 of the N side into the slides 43, 44 of this O side.

Les Bords replies 43 et 44 servent egalement ä donner la rigidite necessaire ä chaque cöte du cadre :et 1'assemblage des quatre cöt6s rdalis6 comme dans l'exemple precMent permet d'obtenir un cadre rigide. The folded edges 43 and 44 also serve to give the necessary rigidity to each side of the frame: and the assembly of the four sides produced as in the preceding example makes it possible to obtain a rigid frame.

Le cadre d6crit a 1'avantage d'etre de construc tion pariiculierement simple, ne necessitant aucune soudure ou rivet, 1'ensemble des Organes qui le cons tituent etant maintenu rigide uniquement par pliage. The frame described has the advantage of being of particularly simple construction, requiring no welding or riveting, all of the Organs which constitute it being held rigid solely by bending.
