Abstract
Description
Candélabre
La présente innention concerne un candélabre du type comprenant un fût vertical tubulaire surmonté d'une crosse tubulaire munie d'un dispositif d'emmanchement. Candelabra
The present invention relates to a candelabra of the type comprising a vertical tubular barrel surmounted by a tubular butt provided with a fitting device.
Pour faciliter la pose de la crosse sur le fût, les candélabres existants comportent fréquemment un manchon cylindrique introduit et assemblé par soudage dans l'extrémité inférieure de la crosse. Afin de s'engager dans le fut, le manchon présente hors de la crosse une queue de diamètre notablement inférieur à celui de sa zone de soudage ; de la sorte, la queue du manchon peut être fixée au fut par le moyen de vis de pression traversant des orifices taraudés ménagés dans la paroi du fut et prenant appui sur la queue. To facilitate the installation of the stick on the barrel, the existing candelabra frequently include a cylindrical sleeve introduced and assembled by welding in the lower end of the stick. In order to engage in the barrel, the sleeve has, outside the butt, a tail with a diameter considerably less than that of its welding zone; in this way, the tail of the sleeve can be fixed to the barrel by means of pressure screws passing through tapped orifices made in the wall of the barrel and bearing on the tail.
Dans les formes d'exécution habituelles de tels candélabres, on utilise des rondelles soudées sur la crosse et/ou sur le fut pour réaliser correctement le centrage et la butée de la crosse sur le fut. I1 en résulte une complication de construction et une augmentation du prix de revient des candélabres. In the usual embodiments of such candelabras, washers welded to the butt and / or on the barrel are used to correctly center and butt the butt on the barrel. This results in a construction complication and an increase in the cost price of the candelabra.
L'invention a notamment pour but de simpliser la fabrication des candélabres métalliques du type décrit tout en contribuant à affiner leur ligne. The invention particularly aims to simplify the manufacture of metal candelabras of the type described while helping to refine their line.
Selon l'invention, le raccordement de la zone cylindri que de fixation du manchon à la crosse avec la queue cylindrique du manchon est décalé extérieurement au-delà de l'extrémité de la crosse, de sorte que le manchon présente entre la zone de soudage et le raccordement une zone cylindrique de centrage dont le logement dans l'extrémité supérieure du fût est assuré avec un faible jeu. According to the invention, the connection of the cylindrical zone for fixing the sleeve to the stock with the cylindrical tail of the sleeve is offset externally beyond the end of the stock, so that the sleeve presents between the welding zone and connecting a cylindrical centering zone, the housing in the upper end of the barrel of which is ensured with little play.
La zone de centrage ainsi ménagée permet d'améliorer d'une manier très sinople -sans recours à aucune pièce additionnelle soudée- le maintien de la crosse sur le fut. De surcroît, la ligne du candélabre ne subit pas de discontinuité,
Un joint annulaire en matériau approprié peut par exemple être interposé entre les extrémités frontales de la crosse et du fut de manière à assurer l'étanchéité de l'assemblage crosse fut et, le cas échéant, à contribuer au centrage du manchon par fluage dans le faible jeu annulaire s'tsistant entre le manchon et le fut.The centering zone thus provided makes it possible to improve in a very sinople manner - without resorting to any additional welded part - the retention of the stock on the barrel. In addition, the line of the candelabrum does not undergo any discontinuity,
An annular seal made of a suitable material can for example be interposed between the front ends of the stock and the barrel so as to ensure the tightness of the stock butt assembly and, if necessary, to contribute to the centering of the sleeve by creep in the weak ring clearance remaining between the sleeve and the barrel.
La description d'un exemple non limitatif qui suit en regard des dessins annexés va permettre de mieux expliciter l'invention. The description of a nonlimiting example which follows with reference to the appended drawings will make it possible to better explain the invention.
La figure 1 représente en élévation un candélabre conforme à l'invention. Figure 1 shows in elevation a candelabra according to the invention.
La figure 2 montre à plus grande échelle et en coupe le détail A de la figure 1. FIG. 2 shows on a larger scale and in section the detail A of FIG. 1.
La figure 3 est une vue éclatée et en coupe du détail A. Figure 3 is an exploded sectional view of detail A.
Comme illustré par la figure 1, le candélabre 10 en acier présente un fut 11 fixée au sol par tout moyen convenable et une crosse 12 portant par exemple un organe d'éclairage ou d'indication. le fut 11 a une forme générale conique ou cylindro-conique; il présente une section droite circulaire vers son extrémité supérieu- re, tout en offrant sur le reste de sa longueur une section ortho- gonale ou circulaire. Un manchon cylindrique 13 soliiaire de la crosse 12 permet de poser et de maintenir la crosse sur l'extrd- mité supérieure à section circulaire du fut. As illustrated in FIG. 1, the steel candelabra 10 has a barrel 11 fixed to the ground by any suitable means and a stock 12 carrying for example a lighting or indication member. the barrel 11 has a generally conical or cylindro-conical shape; it has a circular cross section towards its upper end, while offering over the rest of its length an orthogonal or circular section. A cylindrical sleeve 13 soliiary of the stock 12 allows the stock to be placed and maintained on the upper end with circular cross section of the barrel.
A cet effet, le manchon 13 possède, d'une part, une zone cylindrique 14 qui autorise l'assemblage à la crosse par sou- dage et dont le diamètre DI est très légèrement inférieur au diamettre intérieur de l'extrémité de la crosse, et, d'autre part, une queue 15 de diamètre extérieur D2 notablement inférieur à celui de la zone 14. To this end, the sleeve 13 has, on the one hand, a cylindrical zone 14 which allows assembly to the stock by welding and whose diameter DI is very slightly less than the inside diameter of the end of the stock, and, on the other hand, a tail 15 with an outside diameter D2 significantly smaller than that of the zone 14.
Selon l'invention, il. est prévu sur le machaon une prolongation de la zone 14 au-delà de l'extrémité de la crosse, cette prolongation formant une zone de centrage 16 de diamètre extérieur DI et de longueur L, ceci revenant à décaler vers l'ex térieur de la crosse d'une longueur L le raccordement 17 de la zone de diamètre Dl à la queue de diamètre D2. According to the invention, it. is provided on the swallowtail an extension of the zone 14 beyond the end of the butt, this extension forming a centering zone 16 of outside diameter DI and length L, this amounting to shift towards the outside of the stock of length L the connection 17 of the zone of diameter Dl to the tail of diameter D2.
la zone 14 du manchon est introduite à l'intérieur de la crosse et elle y est assemblée par des soudures-boucton 18 ou par tout autre mode de soudage et/ou de collage. zone 14 of the sleeve is introduced inside the butt and it is assembled there by welds-plankton 18 or by any other mode of welding and / or gluing.
Le montage de la crosse sur le fut s'effectue de la manière suivante : un joint torique 19 en élastomère de section circulaire ou quadrangulaire est engagé sur la zone de centrage 16 du manchon devant l'extrémité frontale 20 de la crosse ; celle-ci
est alors posée sur le fut avec engagement de la queue 15 à l'in
trieur du fut, puis pénétration de la zone de centrage 16 avec
un jeu j le joint 19 est serré entre l'extrémité 20 de la crosse
et l'extrémité frontale 21 du fut et, s'il est en élastomère, il
flue légèrenent dans l'interstioe annulaire j pour contribuer au
centrage du du manchon (figure 2).The mounting of the stock on the barrel is carried out as follows: an O-ring 19 in elastomer of circular or quadrangular section is engaged on the centering zone 16 of the sleeve in front of the front end 20 of the stock; this one
is then placed on the barrel with engagement of the tail 15 at the in
barrel sorter, then penetration of centering zone 16 with
a clearance j the joint 19 is tightened between the end 20 of the stick
and the front end 21 of the barrel and, if it is made of elastomer, it
flow lightly in the annular gap j to contribute to the
centering of the sleeve (Figure 2).
Des vis de pression 22 coopérant avec des orifices 23. Pressure screws 22 cooperating with orifices 23.
ménagés dans la paroi du fut sont alors appliquées contre la queue
15 de façon à innabiliser la crosse.formed in the barrel wall are then applied against the tail
15 so as to stabilize the stick.
Il va de soi qu'on peut apporter des modifications au
mode de réalisation décrit sans pour autant sortir du cadre de
l'invention. It goes without saying that modifications can be made to the
embodiment described without departing from the scope of
the invention.
