Cadre pour vehieule ä deux roues 0n connait des vehicules ä deux roues compor- tant un cadre, execute au moyen de tubes assembles par soudure ou fabrique en töle soudee. Dans les cadres de rette nature, les garde-boue, la suspen.sion des roue:s au moyen de: fourches, les autres accessoi- res tels que tendeur de chaines, marchepieds, porte- bagages ou autres organ.es en töle, sont assembles au. cadre par soudage, rivetage, ou en utilisant une fixation par boulons et ecrous. Frame for a two-wheeled vehicle Two-wheeled vehicles are known comprising a frame, executed by means of tubes assembled by welding or made of welded sheet metal. In natural road frames, mudguards, wheel suspension by means of: forks, other accessories such as chain tensioners, running boards, luggage racks or other sheet metal components, are assembled at. frame by welding, riveting, or using bolt and nut fastening.

Dans rette Borte de vehicules, 1e montage du cadre et de ses parties attenantes au moyen d'as- semblages de ce genre presente notamment 1'incon- venient de necessiter de nombreuses operations et, par consequent, un grand nombre d'heures de tra- vail. In a limited number of vehicles, the assembly of the frame and its adjoining parts by means of assemblies of this type has the particular drawback of requiring numerous operations and, consequently, a large number of hours of work. - okay.

La presente invention, qui vise ä obvier ä cet inconvenient, a pour objet un cadre pour vehicule ä deux roues, caracterise par le fait qu'il presente un corps-porteur en un:e Beule pike fagonne ä la forme, et embouti, ce corps comprenant au moins un garde- boue, 1e support de la direction et des roues, au moins un marchepied et un porte-bagages. The present invention, which aims to obviate this drawback, relates to a frame for a two-wheeled vehicle, characterized by the fact that it has a carrier body in one: body comprising at least one mudguard, the steering and wheel support, at least one step and a luggage rack.

Le dessin annexe represente., ä titre d'exemple, une forme d'execution du cadre objet de 1'invention. Les fig. 1 ä 6 illustrent ladite forme d'exkution. The appended drawing represents, by way of example, one form of execution of the frame which is the subject of the invention. Figs. 1 to 6 illustrate said form of execution.

La fig. 1 en est une vue en elevation ; la fig. 2, une vue en plan de la fig. 1 ; la fig. 3, une vue en bout de 1'extremite anterieure du corps-porteur ; les fig. 4, 5 et 6, des coupes transversales suivant les lignes IV-IV, V-V et VI-VI respectivement de la fig. 2. fig. 1 is an elevation view; fig. 2, a plan view of FIG. 1; fig. 3, an end view of the anterior end of the supporting body; the figs. 4, 5 and 6, transverse sections along lines IV-IV, V-V and VI-VI respectively of FIG. 2.

La fig. 7 est une vue en elevation d'un garde- boue de roue avant destine ä etre monte sur ledit corps-porteur. La fig. 8 est, ä une plus petite erhelle, une vue en elevation d'un.e trottinette presentant ladite forme d'execution du cadre. fig. 7 is an elevational view of a front wheel mudguard intended to be mounted on said carrying body. fig. 8 is, at a smaller scale, an elevational view of a scooter showing said embodiment of the frame.

La fig. 9 est, ä une plus. grande erhelle, une coupe verticale partielle de la fixation, sur ledit corps- porteur, de 1'organe de direction de la trottinette representee ä la fig. B. fig. 9 is, ä a plus. grande erhelle, a partial vertical section of the fixing, on said carrier body, of the steering body of the scooter shown in FIG. B.

Le corps-porteur represente aux fig. 1 ä 6 est en töle d'acier emboutie et constitue d'un Beule pike formant un. corps-porteur de vehicule ä deux roues. Ce corps-porteur, fagonne en une seine operation d'emboutissage, comprend successivement, en partant de 1'avant du cadre, un. support 2 de la direction et du garde-boue de roue avant du vehicule, un mar- chepied 3 et un garde-boue 4 de roue arriere, ledit garde-boue formant en meine temps porte-bagages. Ces differentes parties du corps-porteur 1RTI ID="0001.0270" WI="17" HE="4" LX="1765"LY="1918"> presentent, apres emboutissage de la töle, une section en, forme de U renverse, representee aux fig. 3 ä 6. The supporting body represented in FIGS. 1 to 6 is made of pressed sheet steel and constitutes a Beule pike forming a. carrier body of a two-wheeled vehicle. This supporting body, fashioned into a single stamping operation, comprises successively, starting from the front of the frame, a. support 2 for the steering and the front wheel mudguard of the vehicle, a running board 3 and a rear wheel mudguard 4, said mudguard simultaneously forming a luggage rack. These different parts of the carrier body 1RTI ID="0001.0270" WI="17" HE="4" LX="1765"LY="1918"> have, after stamping the sheet metal, a section in the shape of an inverted U , represented in Figs. 3 to 6.

Au lieu d'etre de 1'acier, la matiere dont est forma 1e corps-porteur pourrait etre de la töle d'alu- minium ou d'alliage d'aluminium, ou encore de la t61e de toute autre matiere mdtallique, ou en matiere plastique. Instead of being steel, the material from which the supporting body is formed could be sheet aluminum or aluminum alloy, or sheet metal of any other metallic material, or plastic material.

Le corps-porteur 1 est destine, par exemple, ä former 1e corps-porteur dune trottinette 5 (fig. 8). A cet effet, la partie anterieure de ce corps, compor- tant 1e support 2 (fig. 9), est pourvue dune piece 6 d'entretoisement, en töle. Cette piece 6, fixee par soudure entre les flasques 7, 7' (fig. 3) du support 2, est destinee ä la fixation d'un tube 8 de direction au moyen de coussinets. 9, 9', en matiere synthetique, par exemple en nylon autolubrifiant. Les coussinets 9, 9' sont fixes,, par exemple par soudure ou vissage, dans la semelle 10 du support 2 et dans la semelle 11 de la pike 6 respectivement. The carrier body 1 is intended, for example, to form the carrier body of a scooter 5 (fig. 8). To this end, the front part of this body, comprising the first support 2 (FIG. 9), is provided with a spacer piece 6, made of sheet metal. This part 6, fixed by welding between the flanges 7, 7' (fig. 3) of the support 2, is intended for fixing a steering tube 8 by means of bearings. 9, 9', in synthetic material, for example in self-lubricating nylon. The pads 9, 9' are fixed, for example by welding or screwing, in the sole 10 of the support 2 and in the sole 11 of the pike 6 respectively.

Pour eviter 1e glissement vers 1e bas du tube de direction, une bague 12, ä ressort, est fixde ä proxi- mit6 de la face superieure du coussinet 9 sur 1e tube 8 dont 1'extremitd superieure 13 regoit 1e guidon 14 (fig. 8) de la trottinette et dont 1'extremite inferieure <B>15</B> est fixee au garderboue 16 de la roue avant, ledit garde-boue etant construit, independamment du corps-porteur 1, par 1'emboutissage dune t61e, de maniere ä prAenter 1a. forme representee en fig. 7. To prevent the steering tube from sliding downwards, a spring-loaded ring 12 is fixed near the upper face of the bearing 9 on the tube 8, the upper end 13 of which receives the handlebar 14 (fig. 8). ) of the scooter and whose lower end <B>15</B> is fixed to the mudguard 16 of the front wheel, said mudguard being constructed, independently of the carrying body 1, by stamping a sheet, way to present 1a. shape represented in fig. 7.

Chacun des flasques des garde-boue 4 et 16 pre- sente dann sa partie centrale une fourche 17, destinee ä la fixation des axes des roues avant et arriere res- pectivement de la trottinette. Each of the flanges of the mudguards 4 and 16 has in its central part a fork 17, intended for fixing the axles of the front and rear wheels respectively of the scooter.

Dans une variante de la fixation du tube de direction 8 sur 1e corps-porteur 1, an pourrait rem- placer les coussinets 9, 9' par des paliers compor- tant des roulements ä billes. In a variant of the fixing of the steering tube 8 on the carrying body 1, the bushings 9, 9' could be replaced by bearings comprising ball bearings.

Le cadre decrit presente notaznment 1'avantage d'avoir une resistance plus dlevee et une securite plus grande qu'un cadre usuel, construit en elements tu- bulaires soudes. The frame described has the advantage in particular of having higher resistance and greater safety than a usual frame, constructed from welded tubular elements.

En outre, compare ä un cadre soude, il neces- site pour sa fabrication une quantit6 de matiere plus reduite, en raison de la suppression de tout procede d'assemblage par soudure, par rivetage, ou de fixa- tion par boulons. et ecrous. La substitution des tubes soudes usuell par de la töle permet de reduire sen- siblement 1e prix de revient de la construction du cadre decrit. In addition, compared to a welded frame, it requires a smaller quantity of material for its manufacture, due to the elimination of any assembly process by welding, riveting, or fastening by bolts. and nuts. The substitution of the usual welded tubes by sheet metal makes it possible to significantly reduce the cost price of the construction of the frame described.
