  Procédé de fabrication d'un cadre ou d'un châssis en matière synthétique thermodur- cissable. 

 <Desc/Clms Page number 2> 

 



   La présente invention est relative à un procédé de fabrication d'un cadre ou d'un châssis en matière      synthétique ou résine thermodurcissable, armée ou non de   @   fibres. 



   On   oonnait   déjà un procédé de fabrication de châssis ou de oadre en une telle matière, -selon lequel on réalise séparément par moulage les éléments longitudi- naux et transversaux constituant le cadre ou le châssis et on assemble ensuite ces éléments entre eux, notamment à leurs extrémités, pour obtenir le châssis ou le cadre fini. 



   Lorsque les éléments constitutifs du châssis ou du cadre sont tubulaires, il est aussi connu de réaliser individuellement ces éléments en deux parties et de coller ensuite celles-ci l'une   à   l'autre pour obtenir lesdits éléments. 



   Le procédé connu présente l'inconvénient de nécessi- ter l'assemblage mutuel des éléments constitutifs du châssis ou du cadre. Un tel assemblage occasionne, dans certains cas, des opérations   à   la fois longues et onéreuses et risque parfois de donner un châssis ou un cadre hors d'équerre et sensiblement déformable. 



   La présente invention a pour objet un nouveau procédé de fabrication de cadre ou de châssis grâce auquel on remédie aux inconvénients susdits. 



   A cet effet, selon ce nouveau procédé, on forme séparément par moulage au moins deux parties du cadre ou du châssis dont les éléments constitutifs forment un contour fermé et présentent une section transversale généralement 

 <Desc/Clms Page number 3> 

 ouverte. En outre, on fait adhérer l'une à l'autre notam- ment par collage, ces deux parties, du cadre ou du châssis ainsi formées afin que les éléments constitutifs de ce cadre ou de ce châssis présentent une section transversale tubu-   laire.   



   Pour faciliter l'adhérence des deux parties formées du cadre ou du châssis, on forme sur ces deux parties des ailes qui permettent d'obtenir des surfaces d'adhérence   suf-   fisantes. 



   D'autres détails et particularités de l'invention apparaîtront au cours de la description des dessins annexés au présent mémoire qui   représ@   lent schématiquement et à titre d'exemple seulement, une forme de réalisation de l'in- vention. 



   La figure 1 est une vue en perspective d'une parti   d'un   nouveau cadre ou châssis selon l'invention. 



   La figure 2 est une vue en perspective analogue de la partie restante de ce cadre ou châssis. 



   La figure 3 est une coupe transversale du nouveau cadre ou châssis. 



   La figure 4 est une coupe d'un moule dans lequel les parties susdites du cadre ou châssis sont formées, 
Dans ces différentes figures, des mêmes notations de référence désignent des éléments identiques. 



   Le nouveau procédé se rapporte à la fabrication d'un cadre ou d'un châssis en matière synthétique thermodur- cissable armée ou non de fibres. 



   Le nouveau procédé consiste à former séparément une première partie 1 et une deuxième partie 2 de ce cadre ou de ce châssis. On forme ces parties 1 et 2 par moulage à la presse par exemple entre un plateau inférieur 3 et un 

 <Desc/Clms Page number 4> 

 plateau supérieur 4 entre lesquels se trouve d'ailleurs un poinçon intermédiaire 5. 



   Après durcissement de la matière entre les plateaux et le poinçon, on obtient, les deux parties 1 et 2 en question. 



   Chaque partie 1 ou 2 est donc constituée d'éléments qui sont formés par exemple des parois médianes 6, des parois extrêmes 7 et des ailes 8 que l'on peut assimiler à des autres parois extrêmes moins larges que les précédentes. Ces divers éléments d'une partie forment ensemble un contour fermé et présentent chacun une section transversale ouverte. 



  Toutefois, ces éléments peuvent aussi présenter, le cas échéant, une section transversale fermée. 



   Après formation des parties susdites 1 et 2, on applique celles-ci l'une sur l'autre après enlèvement du poin- çon 5. De ce fait, on dispose les parois extrêmes 7 de la partie 1 sur les ailes 8 de la partie 2 et les ailes 8 de la partie 1 sur les parois extrêmes 7 de la partie 2, avec interposition éventuelle d'une couche de colle ou d'adhésif. 



  On fait ainsi adhérer lesdites parties 1 et 2 l'une à l'autre par exemple par collage ou par simple contact sous pression et à température voulue. De la sorte, on forme un cadre ou un châssis dont les éléments constitutifs présentent chacun une section transversale tubulaire. Il va de soi que la pré- sence des ailes 8 et la largeur relativement grande de la paroi extrême 7 permettent d'obtenir des surfaces de pose mutuelle des deux parties 1 et 2 qui sont suffisantes pour assurer une bonne adhérence de celles-ci. 



   Il est évident que l'invention n'est pas exclusive- ment limitée à la forme de réalisation représentée et que bien des modifications peuvent être apportées dans la forme,

  A method of manufacturing a frame or a frame in thermosetting synthetic material.

 <Desc / Clms Page number 2>

 



   The present invention relates to a method of manufacturing a frame or a frame in synthetic material or thermosetting resin, reinforced or not with @ fibers.



   There was already a method of manufacturing a frame or frame in such a material, according to which the longitudinal and transverse elements constituting the frame or the frame are produced separately by molding and these elements are then assembled together, in particular at their ends, to obtain the finished sash or frame.



   When the constituent elements of the chassis or of the frame are tubular, it is also known practice to produce these elements individually in two parts and then to glue them together to obtain said elements.



   The known method has the drawback of requiring the mutual assembly of the constituent elements of the chassis or of the frame. Such an assembly causes, in certain cases, operations which are both long and expensive and sometimes risks giving a chassis or a frame out of square and substantially deformable.



   The object of the present invention is a new process for manufacturing a frame or chassis by virtue of which the aforementioned drawbacks are remedied.



   To this end, according to this new process, at least two parts of the frame or of the chassis are formed separately by molding, the constituent elements of which form a closed contour and have a generally cross section.

 <Desc / Clms Page number 3>

 opened. In addition, these two parts of the frame or of the frame thus formed are made to adhere to each other, in particular by gluing, so that the elements constituting this frame or this frame have a tubular cross section.



   To facilitate the adhesion of the two formed parts of the frame or of the chassis, wings are formed on these two parts which make it possible to obtain sufficient adhesion surfaces.



   Other details and features of the invention will become apparent from the description of the drawings appended hereto, which represent schematically and by way of example only, one embodiment of the invention.



   Figure 1 is a perspective view of part of a new frame or chassis according to the invention.



   Figure 2 is a similar perspective view of the remaining part of this frame or chassis.



   Figure 3 is a cross section of the new frame or chassis.



   Figure 4 is a sectional view of a mold in which the aforesaid parts of the frame or chassis are formed,
In these different figures, the same reference notations designate identical elements.



   The new process relates to the manufacture of a frame or a frame of thermosetting synthetic material, whether or not reinforced with fibers.



   The new process consists in separately forming a first part 1 and a second part 2 of this frame or of this chassis. These parts 1 and 2 are formed by press molding, for example between a lower plate 3 and a

 <Desc / Clms Page number 4>

 upper plate 4 between which there is also an intermediate punch 5.



   After hardening of the material between the plates and the punch, the two parts 1 and 2 in question are obtained.



   Each part 1 or 2 therefore consists of elements which are formed, for example, of middle walls 6, end walls 7 and wings 8 which can be likened to other end walls that are less wide than the previous ones. These various elements of a part together form a closed contour and each have an open cross section.



  However, these elements can also have, where appropriate, a closed cross section.



   After forming the aforesaid parts 1 and 2, these are applied one on top of the other after removal of the punch 5. Therefore, the end walls 7 of part 1 are placed on the wings 8 of the part. 2 and the wings 8 of part 1 on the end walls 7 of part 2, with the possible interposition of a layer of glue or adhesive.



  Said parts 1 and 2 are thus made to adhere to one another, for example by gluing or by simple contact under pressure and at the desired temperature. In this way, a frame or a chassis is formed, the constituent elements of which each have a tubular cross section. It goes without saying that the presence of the wings 8 and the relatively large width of the end wall 7 make it possible to obtain mutual laying surfaces of the two parts 1 and 2 which are sufficient to ensure good adhesion of the latter.



   It is obvious that the invention is not exclusively limited to the embodiment shown and that many modifications can be made in the form,

 <Desc / Clms Page number 5>

 the arrangement and constitution of certain of the elements involved in its realization, provided that these modifications are not in contradiction with the object of each of the following claims.



    CLAIMS 1.- A method of manufacturing a frame or a frame made of synthetic material or thermosetting resin characterized in that separately formed by molding at least @ x parts of the frame or the frame of which the constituent elements form a closed contour and have a generally open cross section and in that these two parts of the frame or the chassis thus formed are made to adhere to one another, in particular by gluing, so that the constituent elements of this frame or this frame has a tubular cross section.
