Union signors to Auto Chemnits, Germany Application March 17, 1937, Serial No. 131,492
In March 18 s (c1. zoo-44) Doors for automobiles made or artificial resin materials have not been successful because they were made of artificial resins which are easily i ginal parts, and the novelty consists in this, that the door, which is pressed in one picefrom artin 'ficial resin pressed material containing laminated 4 "pa er or fabric, has, at highly stressed places, re-
inf rcing layers or ribs of the same material imos are welded to the other material by the pressing operation, if with addition of l artificial resin binding agents. In this way the yielding of thematerial at the highly stressed parts is completely prevented and any metal fittings otherwise required are avoided. The re inforci'ng' layers relieve from strain the door 25 frames, which are extremely highly. for
example at the points. of suspension, and distribute the forces over theadjacent zones.
As a further valuable development, the door accordingtotheinventi nhasanarchedesternaJ so surfaceand the reinforcing layersare on the inside. Thisgivesadoor whichisinitself very rigidwhileatthesametimeretainingthe'smooth' outer-surfacewhichishnportantforguidingair without forming eddiea. 35 Preferably the reinforcing layers radiate from the highly parts, whereby-the forces to betakenuparesub-dividedsothatthinnernarrowreinfordnglayersorribsaresufilaent, which facilitate the manufacture of 49 make it more economical.

I
, The provision of the reinforcing layers is carried out according to the invention in such a manner that the pressing operation unites the res info'rcinglayers (preferably in the form of strips) with the remaining material with application of heat, in the manner ofwelding. Preferably a pulverised artificial binding agent is added at the weldingpoints, more especially for "rounding the points of transition. In this way the layers form. reinforcements similar to welded-on sec- .tions, which are not obtained in the usual way by pressing an amorphous mass 'but have throughout the same structure and lamination as the rest of the material. The added artificial resin binding agents fill out any sharp transitions and give a better hold for the layers at these points. r A further valuable detail consists in this, that the ribs are formed with bearing surfaces for attaching the accessories belonging to the door, such as window frames and the like. It thus becomes possible to cut threads directly at these points of greater thickness of material without having to use separately inserted metal bushes. V The strength of the artificial resin ma-- terial used is preferably such that, when the screws are made too tight,'the thread on the screw is damaged.
The invention includes also a number of further valuable details which will bemore fully described below.
A constructional example of the invention is il- Flgureil showsthe doorinsectlonontheline -lIIIin1"lgure 1.
of the door without the inner lining.
According to Figures 1 and 2, mm,=:me in 4 one piece, for example by pressing from artificial resin with laminated paper or fabric as filling material, essentially of a comparatively thin outwardly arched wall I with door stop 2, side edges}, 4 andupperandlower edgeparts I, l; The ,edge parts are preferably integral with the 7 base materialbefore the or according to thepropertles of the material. re plied sepe arately and unite with the wall only during the pressing. The edge 3 is made with reinforcementsat'l andlforseciningthehingmforexample by applying several layers of the same .materialbeforeandimitingthsmwith therestofthematerialduringthepressingoperatimnom'thereinforcodedgepart1estendu strengthening strips 8,10, II and from the edge part 8 extend strengthening strips I2, I 8, M which are all formed by strips of the same material, of which a. number may be superposed,
being united by heat with the remaining material, in the manner of welding during the'press- .ing operation,preferably with addition ot-pulbile, with thin walls verised artificial resin, especially at the rounded parts. In the constructional example illustrated,
these reinforcing strips are made so long that they intersect and join on to the edges lying in their course, for example at l5, I6, l1, and therelining, which is not illustrated, and are preierably provided with directly out threads. A strip 26 screwed on to the window guiding frame carries the usual window raising device 21, the supporting plate of which runs out into two'projections 28, 29 which are clamped, with interposed rubber buffers 3|, in grooves of a strip 30 also made 01' artificial resin and screwed tightly on to theupper, edge. Cut-away parts 32 in the lower edge 6 and in the side edge 4 make possible the flowing away of rain water or the passage of the lock catch.-
I; particularly strong construction oi the side edge 3 is desired, a metal rod 33 is preferably pressed into the-edze,'into which the hinge screws can be screwed;
The materials may be any artificial resins which have a notch shock strength of 20-25 cmkgJcmF and which are reinforced by means of laminated fabrics, paper strips, or other fibrous materials of large area.
What we claim isi 1. A door; more radicals-Iii an with edge parts, said door consisting of a pressing of artificial resin material containing fibrous material in the form of superimposed sheets with reinforcements consisting oi strips of the same material at points subjected to greater stresses and further like reini'orcements distributing said stresses over the area of the door, which reinforcements are homogeneously Joined to the material of the door duringthe pressing and curing operation.
.2. A door as claimed in claim 1, having reinforcing layers rounded oil at the Junctions with the main part of the door,
3. A door as claimed in claim 1, having remforcing layers and reinforcements of the edge parts at the points of attachment of the hinges.
4. A door as claimed in claim 1, in which the reinforcements are formed with bearing surfaces for securing the door furniture, window equip ment and the like. I
5. A door as claimed in claim 1, which is made arched with the reinforcements on the inside.v
6. A door as claimed in claim 1, having edge .thickenings with holes, for the passage of lock elements, and depressions or slots, for accommodating rubber buflers.
7. A door as claimed in claim 1, having metal insertions for increasing the strength at highly stressed edge parts, especially where the hinges are attached.
8. A door as claimed in claim 1, having in the edge part, where the hinges are attached, a metal rod connecting thetwo points of attachment, for increasing the strength. 7
9. A door, more particularly for an automobile, with thin walls and with'edge parts, said door consisting of a pressing of artificial resin material containing fibrous material in the form of superimposed sheets with reinforcements consisting of strips of the same material at points subjected to greater stresses, which reinforcements are homogeneously Joined to the material or the door during the pressing and curing. operation.
