Abstract

Method of manufacturing plastic articles, especially seats comprising a base (10) and parts erected on the said base, such as a back-rest and/or arm-rests (11, 11a). The base (10) and the other parts (11, 11a) of the seat are firstly produced, by injection-blow moulding, and next the said parts are assembled together by the cooperation of the shapes of male (30, 31) and female (20, 21) means, assembly taking place while the base (10), including the female means (20, 21), has not yet cooled down entirely, so that the shrinkage which accompanies the cooling-down of the plastic immobilises, by blocking, the male means in the female means.

Description

L'invention a pour objet un procédé de fabrication de sièges ou analogues en matière plastique et les sièges ou analogues obtenus par sa mise en oeuvre. The subject of the invention is a method of manufacturing seats or the like in plastic and the seats or the like obtained by its use.

On sait que l'on utilise, pour la fabrication de sièges en matière plastique de formes relativement complexes, présentant un bel aspect de finition, les techniques dites de " roto -moul age " qui font appel à un moule ou cavité fermée mis en rotation dans une chambre de chauffage. Si ces techniques donnent satisfaction elles ne permettent pas, cependant, la fabrication de quantités importantes dans des conditions économiques optimales. We know that we use, for the manufacture of plastic seats of relatively complex shapes, with a nice finish appearance, the techniques called "roto-mold age" which use a closed mold or cavity set in rotation in a heating chamber. If these techniques are satisfactory, they do not, however, allow the manufacture of large quantities under optimal economic conditions.

C'est, par conséquent, un but de l'invention de fournir un procédé de fabrication d'objets en matière plastique suivant des quantités importantes et dans des conditions économiques satisfaisantes, tant au point de vue coût que temps de production, qui permette de s'affranchir des inconvénients liés aux techniques de "roto-moulage" tout en conduisant à des sièges ou ana logues d d'aspect satisfaisant, nonobstant leur forme qui peut être complexe. It is therefore an object of the invention to provide a process for manufacturing plastic objects in large quantities and under satisfactory economic conditions, both in terms of cost and production time, which allows overcome the drawbacks associated with "rotational molding" techniques while leading to seats or analogues of satisfactory appearance, notwithstanding their shape which can be complex.

Le procédé selon l'invention, de fabrication d'objets en matière plastique, notamment dé sièges ou analogues comportant une partie d'assise ou embase et des parties érigées sur ladite embase, comme un dossier et/ou des accoudoirs, est caractérisé en ce que l'on réalise d'abord par injection soufflage la partie d'assise et les autres parties du siège et en ce que l'on assemble ensuite lesdites parties entre elles par coopération de formes de moyens mâles et femelles, l'assemblage étant conduit alors que la partie portant les moyens femelles n'est pas encore totalement refroidie après injection soufflage de sorte que le retrait qui accompagne le refroidissement de la matière plastique immobilise par blocage les moyens mâles dans les moyens femelles. The method according to the invention, for manufacturing plastic objects, in particular seats or the like comprising a seat part or base and parts erected on said base, such as a backrest and / or armrests, is characterized in that that the seat part and the other parts of the seat are first produced by injection blowing and in that the said parts are then assembled together by cooperation of forms of male and female means, the assembly being carried out while the part carrying the female means is not yet completely cooled after injection blowing so that the shrinkage which accompanies the cooling of the plastic material immobilizes by blocking the male means in the female means.

Dans une réalisation particulièrement avanta geuse, les moyens femelles sont des forages traversants ménagés dans l'assise du siège ou analogue et les moyens mâles sont des plots prévus sur le dossier et/ou les accoudoirs et qui sont munis de détrompeurs pour leur positionnement par rapport auxdits forages traversants. In a particularly advantageous embodiment, the female means are through boreholes formed in the seat of the seat or the like and the male means are studs provided on the backrest and / or the armrests and which are provided with locating pins for their positioning relative to to said through holes.

D'autres caractéristiques et avantages de l'invention apparaîtront de la description qui suit, faite à titre d'exemple et en référence au dessin annexé, dans lequel
- la figure 1 est une vue schématique, en perspective éclatée, d'un siège obtenu par mise en oeuvre du procédé selon l'invention ;
- la figure 2 est une vue schématique en coupe illustrant l'assemblage des parties constitutives d'un siège ;
- la figure 3 est une vue en élévation d'un plot d'assemblage ;
- la figure 4 est une vue en coupe, à plus grande échelle, selon la ligne 4-4 de la figure 3.Other characteristics and advantages of the invention will appear from the description which follows, given by way of example and with reference to the appended drawing, in which
- Figure 1 is a schematic view, in exploded perspective, of a seat obtained by implementing the method according to the invention;
- Figure 2 is a schematic sectional view illustrating the assembly of the constituent parts of a seat;
- Figure 3 is an elevational view of an assembly pad;
- Figure 4 is a sectional view, on a larger scale, along line 4-4 of Figure 3.

On se réfère d'abord à la figure 1 qui montre, en perspective éclatée, un siège du type de ceux connus sous le nom de "réhausseurs" et qui est constitué, le plus simplement, par une partie d'assise 10 et deux accoudoirs latéraux 11 et 11a érigés sur l'assise, un tel siège étant destiné à être utilisé par un enfant pour mettre celui-ci à une plus grande hauteur lorsque le réhausseur est posé sur un siège d'automobile ou sur une chaise usuelle, l'invention n'étant pas, bien entendu, limitée à ce type de siège ni d'utilisation. Reference is first made to FIG. 1 which shows, in exploded perspective, a seat of the type of those known under the name of "booster seats" and which consists, most simply, of a seat part 10 and two armrests lateral 11 and 11a erected on the seat, such a seat being intended to be used by a child to put it at a greater height when the booster seat is placed on a car seat or on a usual chair, the The invention is not, of course, limited to this type of seat or use.

La partie d'assise ou embase 10, à contour plan sensiblement rectangulaire à coins arrondis est, selon l'invention, fabriquée par injection soufflage d'une matière plastique, avantageusement du polyéthylène haute densité, pour définir une surface d'assise 12, une base 13 sensiblement parallèle à l'assise, une paroi frontale 14, des parois latérales 15 et 16 et une paroi postérieure 17 de hauteur légèrement supérieure aux précédentes pour former une amorce de dosseret 18. The seat part or base 10, with a substantially rectangular plane contour with rounded corners, is, according to the invention, produced by injection blowing of a plastic material, advantageously high density polyethylene, to define a seat surface 12, a base 13 substantially parallel to the seat, a front wall 14, side walls 15 and 16 and a rear wall 17 of height slightly greater than the previous ones to form a backsplash primer 18.

Conformément à l'invention, l'assise 12 et la base 13 sont également réunies par des parois comme 19, figure 2, qui ménagent quatre forages traversants groupés par paires au voisinage des parois 15 et 16, respectivement. Dans la réalisation décrite et représentée, les forages traversants dont deux sont référencés 20 et 21 présentent chacun une partie sensiblement cylindrique 22, débouchant sur la face d'assise 12 de l'embase, dont la longueur est environ la moitié de la hauteur de l'embase et qui est reliée à une partie légèrement tronconique, 23, débouchant sur la base 13, par un épaulement 24. According to the invention, the seat 12 and the base 13 are also joined by walls like 19, FIG. 2, which provide four through holes grouped in pairs in the vicinity of the walls 15 and 16, respectively. In the embodiment described and shown, the through boreholes, two of which are referenced 20 and 21 each have a substantially cylindrical part 22, opening onto the seat face 12 of the base, the length of which is approximately half the height of l 'base and which is connected to a slightly frustoconical part, 23, opening onto the base 13, by a shoulder 24.

Les forages traversants comme 20 et 21 sont prévus pour recevoir des plots comme 30 et 31, associés par paire à chacun des accoudoirs 11 et pila, eux aussi fabriqués par injection soufflage de la même matière plastique que celle servant à fabriquer l'embase 10. Through holes like 20 and 21 are designed to receive studs like 30 and 31, associated in pairs with each of the armrests 11 and pila, also made by injection blowing from the same plastic as that used to make the base 10.

Comme bien visible sur les figures 3 et 4, chaque plot 30,31 est conformé suivant une partie d'extrémité 35, cylindrique, reliée à la face inférieure 36 de l'accoudoir d'abord par une zone tronconique 37 puis par une partie à nouveau cylindrique 38, formant clips, et qui est munie de deux méplats diamétralement opposés 40 et 41, figure 4, servant de détrompeurs.As clearly visible in FIGS. 3 and 4, each stud 30, 31 is shaped according to an end part 35, cylindrical, connected to the lower face 36 of the armrest first by a frustoconical zone 37 then by a part to new cylindrical 38, forming clips, and which is provided with two diametrically opposed flats 40 and 41, FIG. 4, serving as polarizers.

Le montage du siège décrit et représenté s'effectue le plus simplement en présentant les accoudoirs 11 et lia en regard de l'embase 10 alors que celleci n'est pas encore totalement refroidie après injection soufflage et en introduisant dans les forages traversants comme 20 et 21 les plots comme 30, 31 des accoudoirs préalablement fabriqués et, quant à eux, totalement refroidis. Après montage des plots dans les forages traversants jusqu'à ce que la partie de plus grand diamètre de la zone tronconique 37 coopère avec l'épaulement 24, -ce montage étant facilité par la déformabilité des forages et des plots des accoudoirs-, ces derniers sont solidement fixés à l'embase tant par effet de clipage que par le retrait de la matière plastique constitutive de l'embase au voisinage des forages traversants lors du refroidissement complet de ladite embase. The mounting of the seat described and shown is carried out most simply by presenting the armrests 11 and 11a opposite the base 10 while this is not yet completely cooled after injection blowing and by introducing into the through holes as 20 and 21 the pads like 30, 31 of the armrests previously manufactured and, for their part, completely cooled. After mounting the studs in the through boreholes until the portion of larger diameter of the frustoconical zone 37 cooperates with the shoulder 24, this mounting being facilitated by the deformability of the boreholes and of the studs of the armrests, the latter are securely attached to the base both by clipping effect and by the withdrawal of the plastic material constituting the base in the vicinity of the through holes during the complete cooling of said base.

A la fixation satisfaisante des accoudoirs sur l'embase 10 contribue également le fait que lesdits accoudoirs présentent, sur leur face inférieure, une protubérance ou dent 45 de forme conjuguée de celle d'un évidement 46 de l'embase avec lequel elle est destiné à coopérer. The satisfactory attachment of the armrests to the base 10 also contributes to the fact that the said armrests have, on their underside, a protuberance or tooth 45 of shape combined with that of a recess 46 in the base with which it is intended to cooperate.

Un siège selon l'invention peut être muni d'une housse qui le garnit, en totalité ou en partie, et qui peut être fixée, en particulier sur l'embase, par des boutons-pression ou des moyens analogues mis en place dans des trous réalisés directement dans le moule d'injection soufflage par des broches et en contre dépouille ou par perçage après moulage.  A seat according to the invention can be provided with a cover which covers it, in whole or in part, and which can be fixed, in particular on the base, by snaps or similar means put in place in holes made directly in the injection mold blow molding by pins and undercut or by drilling after molding.
