Un vélo doit être dimensionné de manière à ce qu'il corresponde à la morphologie de son utilisateur. Dans la plupart des cas, le vendeur utilise son savoir-faire sans faire appel à des moyens techniques particuliers. Il se contente de vérifier que son client a une position satisfaisante sur le vélo.A bicycle must be sized so that it matches the morphology of its user. In most cases, the seller uses his know-how without calling on special technical means. He just checks that his client has a satisfactory position on the bike.
Les vélos réalisés pour une pratique fréquente sont fabriqués à partir de pièces produites industriellement et assemblées de manière artisanale. Le fabricant mesure l'utilisateur et choisit les pièces les mieux adaptées parmi celles existantes, sur la base de tabelles. Les pièces mobiles telles que guidon et selle sont ensuite ajustées à l'utilisateur.The bikes made for frequent practice are made from industrially produced parts and assembled in a traditional way. The manufacturer measures the user and chooses the most suitable parts from among the existing ones, on the basis of tables. The moving parts such as handlebars and saddle are then adjusted to the user.
Malgré ces mesures, il est apparu que, lors d'une pratique intensive de ce sport, il est souhaitable de déterminer de manière encore plus précise les cotes du vélo. Ces dernières peuvent être déterminées, par anthropométrie, par exemple au moyen de l'appareil décrit dans la demande de brevet CH 1983/99, ayant pour titre "Dispositif de mesure anthropométrique", et/ou au moyen d'un vélo dynamométrique tel que celui commercialisé par la maison Ergomotion Lugano (Suisse) sous le nom de "DynaOne". En procédant ainsi, il est possible de connaître les cotes optimales du vélo. Il n'est toutefois pas facile de les garantir lors du montage des pièces constituantes de série et même lors d'une fabrication sur mesure.Despite these measures, it appeared that, during an intensive practice of this sport, it is desirable to determine even more precisely the dimensions of the bicycle. The latter can be determined, by anthropometry, for example by means of the apparatus described in patent application CH 1983/99, having the title "Anthropometric measuring device", and / or by means of a dynamometric bicycle such as the one marketed by Ergomotion Lugano (Switzerland) under the name "DynaOne". In in doing so, it is possible to know the optimal dimensions of the bicycle. However, it is not easy to guarantee them during the assembly of the standard component parts and even during custom manufacturing.
En effet, le réglage des vélos se fait généralement au moyen d'outils simples tels que règles ou rapporteurs d'angles. La précision ainsi obtenue est médiocre. Or, il est apparu qu'un réglage inadéquat pouvait conduire à des problèmes de santé pour l'utilisateur, surtout lorsqu'il pratique ce sport intensément. Le but de la présente invention est de proposer un outil performant, permettant de vérifier les pièces rigides et positionner les pièces mobiles constituant un vélo, de manière à ce qu'il soit mieux adapté à son utilisateur.Indeed, the adjustment of bikes is generally done using simple tools such as rulers or angle reporters. The precision thus obtained is poor. However, it appeared that an improper adjustment could lead to health problems for the user, especially when he practices this sport intensely. The purpose of the present invention is to provide an efficient tool, making it possible to check the rigid parts and position the moving parts constituting a bicycle, so that it is better suited to its user.
Dans ce but, le banc comprend une table et des premiers et des deuxièmes moyens de fixation du vélo sur la table. Cette dernière porte, en outre, un dispositif de mesure destiné à déterminer au moins une dimension caractéristique du vélo. Ainsi, grâce au fait que le dispositif de mesure est directement porté par la table sur laquelle le vélo est fixé, il est possible de garantir une grande précision dans la détermination des cotes du vélo.For this purpose, the bench includes a table and first and second means for fixing the bicycle to the table. The latter also carries a measuring device intended to determine at least one characteristic dimension of the bicycle. Thus, thanks to the fact that the measuring device is directly carried by the table on which the bicycle is fixed, it is possible to guarantee high accuracy in determining the dimensions of the bicycle.
De manière avantageuse, le dispositif de mesure comprend un patin monté coulissant sur la table et un bras monté pivotant sur le patin. Il est ainsi possible de placer le dispositif au droit du pédalier et de disposer le bras de manière à pouvoir mesurer la hauteur de l'axe du pédalier, la hauteur de selle, l'angle du tube montant de selle et la hauteur de cadre. De plus, comme le bras est monté pivotant sur le patin, il est possible de mesurer l'inclinaison du tube montant de selle.Advantageously, the measuring device comprises a shoe mounted sliding on the table and an arm pivotally mounted on the shoe. It is thus possible to place the device to the right of the crankset and to arrange the arm so as to be able to measure the height of the axis of the crankset, the seat height, the angle of the seat post and the frame height. In addition, as the arm is pivotally mounted on the pad, it is possible to measure the inclination of the seat post tube.
Afin de faciliter la mesure de la hauteur de l'axe du pédalier, le bras est muni de moyens de liaison destinés à coopérer avec le logement de l'arbre du pédalier pour les rendre solidaires. Il comporte, en outre, une règle et un palpeur pour mesurer la hauteur de la selle en référence à l'axe de l'arbre de pédalier.In order to facilitate the measurement of the height of the pedal axis, the arm is provided with connecting means intended to cooperate with the housing of the pedal shaft to make them integral. It also includes a rule and a feeler to measure the height of the saddle with reference to the axis of the bottom bracket shaft.
La mesure de la longueur du cadre et des cotes relatives au guidon et à sa potence est facilitée du fait que le banc comporte, en outre, deux hampes fixées à la table et une traverse montée coulissante sur ces hampes.Measuring the length of the frame and the dimensions relating to the handlebars and its stem is made easier by the fact that the bench further comprises two shafts fixed to the table and a cross member slidingly mounted on these shafts.
De manière avantageuse, chacune des hampes est munie d'une règle destinée à mesurer la position de la traverse. De plus, la traverse porte une règle et un patin muni d'une fourche, pour mesurer la position de la potence et du guidon.Advantageously, each of the stems is provided with a ruler intended to measure the position of the crosspiece. In addition, the crosspiece carries a ruler and a shoe fitted with a fork, to measure the position of the stem and the handlebars.

Le banc illustré à la figure 2 comprend essentiellement une table 10, deux hampes 12 et 14, deux supports 16 et 18, un dispositif de mesure 20 et une traverse 22.The bench illustrated in FIG. 2 essentially comprises a table 10, two shafts 12 and 14, two supports 16 and 18, a measuring device 20 and a crosspiece 22.
La table 10 est formée d'un profilé de section carrée 24 et d'une baguette de section rectangulaire 26, fixée sur le profilé 24, qui définissent ensemble un axe longitudinal A-A. Elle est munie d'un châssis 28, partiellement représenté et destiné à prendre appui sur le sol ou sur un établi, et qui comporte des moyens de réglage classiques, pour définir la position du banc, notamment son horizontalité. Ces moyens n'ont pas été représentés pour éviter de surcharger le dessin et la description.The table 10 is formed by a profile of square section 24 and a rod of rectangular section 26, fixed on the profile 24, which together define a longitudinal axis A-A. It is provided with a chassis 28, partially shown and intended to rest on the ground or on a workbench, and which comprises conventional adjustment means, to define the position of the bench, in particular its horizontality. These means have not been shown to avoid overloading the drawing and the description.
Les hampes 12 et 14, compremient chacune un socle 30, un mât 32 monté sur le socle 30, et une règle 34 fixée au mât 32. Ces différentes pièces sont assemblées entre elles et avec la table 10 au moyen de vis qui ont été partiellement représentées au dessin mais n'ont pas été référencées. Le mât de la hampe 12 est orienté selon un axe B-B vertical, perpendiculaire à l'axe A-A. Le mât de la hampe 14 est disposé parallèlement à l'axe B-B.The shafts 12 and 14 each include a base 30, a mast 32 mounted on the base 30, and a rule 34 fixed to the mast 32. These different parts are assembled together and with the table 10 by means of screws which have been partially shown in the drawing but have not been referenced. The mast of the shaft 12 is oriented along a vertical axis BB, perpendicular to the axis AA. The mast of the pole 14 is arranged parallel to the axis BB.
Les supports 16 et 18, sont tous les deux formés d'un patin 36 et d'une potence 38.The supports 16 and 18 are both formed by a shoe 36 and a bracket 38.
Comme on peut le voir sur les figures 3 et 4, le patin 36 est construit de manière à former une coulisse 40 destinée à être engagée dans la baguette 26, pour permettre le coulissement du support 16 ou 18 sur la table 10. II est muni d'un trou taraudé 41 et d'une clé de serrage 42, engagée dans le trou taraudé 41. Un sabot 43, s'étendant sur le côté de la coulisse 40 munie du trou taraudé 41, est pressé contre la baguette 26 par serrage de la clé 42, pour bloquer le socle 16 ou 18 sur la table 10. Des goupilles, représentées au dessin, mais non référencées, assurent le positionnement du sabot 43 sur le patin 36.As can be seen in Figures 3 and 4, the shoe 36 is constructed so as to form a slide 40 intended to be engaged in the rod 26, to allow the support 16 or 18 to slide on the table 10. It is provided a tapped hole 41 and a tightening key 42, engaged in the tapped hole 41. A shoe 43, extending on the side of the slide 40 provided with the tapped hole 41, is pressed against the rod 26 by tightening of the key 42, to block the base 16 or 18 on the table 10. Pins, shown in the drawing, but not referenced, ensure the positioning of the shoe 43 on the shoe 36.
Le support 16, représenté de manière détaillée sur la figure 3, est destiné à fixer le vélo par sa partie avant, comme cela sera expliqué plus loin. A cet effet, sa potence 38 est munie de quatre trous 44, cylindriques dont les axes sont parallèles entre eux et identifiés par les lettres a à d. Un arbre 46, formé d'une tige cylindrique, filetée à ses deux extrémités, est engagé dans l'un ou l'autre des trous 44. L'arbre 46 définit un axe latéral C-C, perpendiculaire aux axes A-A et B-B. Il porte deux bagues d'ajustement 48, disposées de part et d'autre de la potence 38, et deux clés de serrage 50, chacune vissée sur l'une des extrémités filetées de l'arbre 46. On relèvera que, sur la figure 2, l'arbre 46 avec les bagues 48 et les clés 50 ont été disposées au-dessus du support 16, de manière à mieux pouvoir en voir la structure.The support 16, shown in detail in Figure 3, is intended to fix the bike by its front part, as will be explained later. To this end, its bracket 38 is provided with four cylindrical holes 44 whose axes are parallel to each other and identified by the letters a to d. A shaft 46, formed of a cylindrical rod, threaded at its two ends, is engaged in one or the other of the holes 44. The shaft 46 defines a lateral axis C-C, perpendicular to the axes A-A and B-B. It carries two adjustment rings 48, arranged on either side of the bracket 38, and two tightening wrenches 50, each screwed onto one of the threaded ends of the shaft 46. It will be noted that, in the figure 2, the shaft 46 with the rings 48 and the keys 50 have been arranged above the support 16, so as to be able to better see the structure thereof.
Le support 18 est représenté de manière plus détaillée sur la figure 4. Il est destiné à fixer le vélo par sa partie arrière, comme cela sera expliqué plus loin. Sa potence 38 porte un sélecteur 52, de forme parallélépipédique, muni sur quatre de ses côtés d'une goupille de fixation 54, ces goupilles étant coaxiales par paires, les paires étant perpendiculaires entre elles. Les goupilles 54 présentent un corps 54a et un doigt 54b dont l'extrémité est filetée. Des clés de serrage 55 peuvent y être vissées.The support 18 is shown in more detail in FIG. 4. It is intended to fix the bicycle by its rear part, as will be explained more far. Its bracket 38 carries a selector 52, of parallelepiped shape, provided on four of its sides with a fixing pin 54, these pins being coaxial in pairs, the pairs being perpendicular to each other. The pins 54 have a body 54a and a finger 54b, the end of which is threaded. Tightening wrenches 55 can be screwed into it.
Le corps 54a est relié au doigt 54b par une portée 54c. Les deux paires de goupilles 54 présentent des distances différentes entre leurs deux portées 54c, les goupilles utilisées étant choisies en fonction des caractéristiques du cadre.The body 54a is connected to the finger 54b by a bearing 54c. The two pairs of pins 54 have different distances between their two spans 54c, the pins used being chosen according to the characteristics of the frame.

Les curseurs 86 et 88 portent respectivement des palpeurs 92, 94, alors que le curseur 90 sert de support à deux palpeurs portant les références 95 et 96, destinés à mesurer certaines cotes du vélo, 5 comme cela sera expliqué plus loin. Seul le curseur 90 est décrit ci-après de manière détaillée, en référence à la figure 6. Les deux autres seront décrits en référence à la figure 11.74d whose function will be specified later. The measuring device 20 further comprises three cursors 86, 88 and 90 visible in FIG. 2. The cursors 86 and 88 respectively carry probes 92, 94, while the cursor 90 serves as a support for two probes bearing the references 95 and 96, intended to measure certain dimensions of the bicycle, 5 as will be explained later. Only the cursor 90 is described below in detail, with reference to FIG. 6. The other two will be described with reference to FIG. 11.
Comme le montre la figure 6, le curseur 90 est formé d'un corps 90a, de forme générale parallélépipédique, muni, sur l'une de ses grandes faces, Ï0 d'une gorge 90b et sur l'autre grande face d'une saillie 90c.As shown in FIG. 6, the cursor 90 is formed by a body 90a, of generally parallelepiped shape, provided, on one of its large faces, with a groove 90b and on the other large face with a projection 90c.
La gorge 90b est fermée au moyen d'une plaquette 98, fixée au corps au moyen de vis 100, pour former une coulisse 90d destinée à recevoir la barre 74. Le curseur 90 est, en outre, muni, sur l'une des parois de la gorge 90b, d'un sabot 102, de goupilles 104 solidaires du sabot et d'une molette à visThe groove 90b is closed by means of a plate 98, fixed to the body by means of screws 100, to form a slide 90d intended to receive the bar 74. The cursor 90 is, moreover, provided on one of the walls groove 90b, a shoe 102, pins 104 integral with the shoe and a screw wheel
15 106 engagée dans le corps 90a du curseur, pour former ensemble et de manière classique, un système de blocage du curseur 90 sur la barre 74. La saillie 90c est munie d'un trou 90e dans lequel le palpeur 96 est engagé. Un organe élastique, disposé dans le trou 90e et non visible au dessin, assure le positionnement du palpeur 96. Il serait également possible de le fixer au 0 moyen d'une clé de serrage ou d'une molette.106 106 engaged in the body 90a of the cursor, to form together and in a conventional manner, a system for blocking the cursor 90 on the bar 74. The projection 90c is provided with a hole 90e in which the probe 96 is engaged. An elastic member, placed in the hole 90e and not visible in the drawing, ensures the positioning of the probe 96. It would also be possible to fix it by means of a tightening key or a thumb wheel.
Le palpeur 96 est formé d'une tige cylindrique dont une extrémité 96a est conique. Il est muni d'un plat 96b sur lequel une réglette 108 est fixée, par exemple par collage.The feeler 96 is formed by a cylindrical rod, one end of which 96a is conical. It is provided with a dish 96b on which a strip 108 is fixed, for example by gluing.
En référence à la figure 2, il apparaît que la traverse 22 est essentiellement 5 formée d'un barreau 110 de section sensiblement rectangulaire et de deux plots de liaison 112 et 114, destinés à fixer, de manière amovible, la traverse 22 sur les hampes 12 et 14. Comme cela est visible sur la figure 7, le barreau 110 comporte deux saignées 110a et 110b, disposées longitudinalement à chacune de ses extrémités et ouvertes sur ses grandes faces, respectivement en regard des hampes 12 et 14. Il porte un rail 115, fixé sur l'une des grandes faces, dans le prolongement de la saignée 110a, au moyen de vis 116. Le rail 115 porte deux curseurs 117 et 118 (figure 2). Le rail et les curseurs sont réalisés au moyen d'un ensemble vendu par la maison Hoerbiger (Suisse) sous la référence RK-FD 15S.Referring to Figure 2, it appears that the crosspiece 22 is essentially formed of a bar 110 of substantially rectangular section and two connecting studs 112 and 114, intended to removably fix the crosspiece 22 on the stems 12 and 14. As can be seen in FIG. 7, the bar 110 has two grooves 110a and 110b, arranged longitudinally at each of its ends and open on its large faces, respectively opposite the shafts 12 and 14. It carries a rail 115, fixed on one of the large faces, in the extension of the groove 110a, by means of screws 116. The rail 115 carries two sliders 117 and 118 (FIG. 2). The rail and the sliders are produced using a set sold by the house Hoerbiger (Switzerland) under the reference RK-FD 15S.
Une règle 120 est montée sur le barreau 110, sur sa face latérale supérieure, disposée de manière à ce qu'elle s'étende vers l'avant en deçà du guidon et vers l'arrière au-delà du tube de selle et fixée au moyen de vis 121.A rule 120 is mounted on the bar 110, on its upper lateral face, arranged so that it extends forwards below the handlebars and rearwards beyond the seat tube and fixed to the screw means 121.
Les plots de liaison 112 et 114 (figure 2) comportent tous les deux un corps 122 percé d'un trou cylindrique 122a dans lequel est engagé le mât 32. Une pièce mobile 124, fixée au corps 122 au moyen d'une clé de serrage 126, assure, de manière classique, le verrouillage des plots 112 et 114 sur les mâts 32, afin de les rendre solidaires. Les corps 122 sont munis d'un trou fileté dont l'axe est parallèle à l'axe C-C et pratiqué dans l'extrémité opposée au côté muni du trou 122a, disposé de manière à ce qu'il se trouve en regard des saignées 110a ou 110b et destiné à recevoir une clé de serrage 128.The connecting studs 112 and 114 (FIG. 2) both comprise a body 122 pierced with a cylindrical hole 122a in which the mast 32 is engaged. A movable part 124, fixed to the body 122 by means of a tightening key 126, conventionally ensures the locking of the studs 112 and 114 on the masts 32, in order to make them integral. The bodies 122 are provided with a threaded hole the axis of which is parallel to the axis CC and made in the end opposite to the side provided with the hole 122a, arranged so that it is opposite the grooves 110a or 110b and intended to receive a tightening key 128.
Les clés de serrage 128 des plots 112 et 114 sont respectivement engagées dans les saignées 110a et 110b et assurent la fixation de manière amovible du barreau 110 sur les plots 112 et 114.The tightening keys 128 of the studs 112 and 114 are respectively engaged in the grooves 110a and 110b and ensure the removable fixing of the bar 110 on the studs 112 and 114.
Les curseurs 117 et 118 portent respectivement des outils de mesure 130 et 132 représentés sur la figure 8. L'outil de mesure 130 comporte un support 134 fixé rigidement sur le curseur 117, au moyen de vis 136, une barre 138, un curseur 140 et un palpeur 142. La barre 138 présente une structure comparable à la barre 74, mais sa longueur est plus faible. Elle est fixée au support 134 au moyen d'une molette 143 de manière similaire à la fixation du levier 70 sur le patinThe cursors 117 and 118 respectively carry measurement tools 130 and 132 shown in FIG. 8. The measurement tool 130 comprises a support 134 rigidly fixed on the cursor 117, by means of screws 136, a bar 138, a cursor 140 and a probe 142. The bar 138 has a structure comparable to the bar 74, but its length is weaker. It is fixed to the support 134 by means of a thumb wheel 143 in a similar manner to the fixing of the lever 70 on the shoe.
62. Le curseur 140 est monté sur la barre 138 de la même façon que le curseur 96 sur la barre 74. C'est pourquoi ces différentes pièces ne seront pas décrites de manière plus précise.62. The cursor 140 is mounted on the bar 138 in the same way as the cursor 96 on the bar 74. This is why these different parts will not be described in more detail.
Le palpeur 142, illustré à la figure 9, est venu de matière avec le corps du curseur 140. Il présente la forme d'un prisme dont une arrête 142a est orientée vers le haut.The probe 142, illustrated in FIG. 9, came integrally with the body of the cursor 140. It has the shape of a prism, one stop 142a of which is oriented upwards.
L'outil de mesure 132 visible sur la figure 8, est formé d'un support 144, en équerre avec deux bras 144a et 144b, d'un mât 145 et d'une fourche 146. Le bras 144a est fixé rigidement au curseur 118 au moyen de vis 147. Le bras 144b s'étend par-dessus la traverse 22 et porte à son extrémité le mât 145 de forme cylindrique, fixé, par exemple, par chassage dans le support 144.The measurement tool 132 visible in FIG. 8, is formed of a support 144, at right angles to two arms 144a and 144b, of a mast 145 and of a fork 146. The arm 144a is rigidly fixed to the slider 118 by means of screws 147. The arm 144b extends over the crosspiece 22 and carries at its end the mast 145 of cylindrical shape, fixed, for example, by driving into the support 144.
La fourche 146 est représentée en perspective sur la figure 10, assemblée en a et en éclaté en b. Elle comporte un bras 148, une main 150, un organe de déport 152 et une règle 154. Le bras 148 est formé d'un manchon fendu 148a, et d'une tige 148b.The fork 146 is shown in perspective in FIG. 10, assembled in a and exploded in b. It comprises an arm 148, a hand 150, an offset member 152 and a rule 154. The arm 148 is formed by a split sleeve 148a, and a rod 148b.
Le manchon 148a comprend une ouverture centrale 148c, destinée à recevoir le mât 145 et une fente 148d, débouchant dans l'ouverture 148c et formant deux lèvres 148e. Un trou 148f perpendiculaire à la fente 148d traverse les deux lèvres 148e et forme deux portions, dont l'une est filetée. Une clé de serrage, qui n'est pas visible au dessin, est engagée dans la portion non filetée et vissée dans la portion filetée du trou 148f, pour assurer le serrage du bras 148 sur le mât 145. La main 150 comprend un poignet 150a et deux doigts horizontaux 150b et 150c disposés parallèlement et dans le prolongement du poignet 150a. La distance entre les doigts 150b et 150c est égale au diamètre du tube formant le guidon 3. La face supérieure du doigt inférieur 150c se trouve dans le prolongement de la face inférieure de la tige 148b.The sleeve 148a includes a central opening 148c, intended to receive the mast 145 and a slot 148d, opening into the opening 148c and forming two lips 148e. A hole 148f perpendicular to the slot 148d passes through the two lips 148e and forms two portions, one of which is threaded. A tightening key, which is not visible in the drawing, is engaged in the unthreaded portion and screwed into the threaded portion of the hole 148f, to ensure the tightening of the arm 148 on the mast 145. The hand 150 comprises a wrist 150a and two horizontal fingers 150b and 150c arranged in parallel and in the extension of the wrist 150a. The distance between the fingers 150b and 150c is equal to the diameter of the tube forming the handlebar 3. The upper face of the lower finger 150c is located in the extension of the lower face of the rod 148b.
L'organe de déport 152 est de forme parallélépipédique, intercalé entre l'extrémité libre de la tige 148b et du poignet 150a, qui sont alignés selon une direction parallèle à l'axe C-C. Tant la tige 148b, le poignet 150a que l'organe de déport 152 sont percés de trous dans lesquels des vis 156 sont engagées pour assurer l'assemblage de la fourche 146.The offset member 152 is of parallelepiped shape, interposed between the free end of the rod 148b and the wrist 150a, which are aligned in a direction parallel to the axis C-C. Both the rod 148b, the wrist 150a and the offset member 152 are pierced with holes in which screws 156 are engaged to ensure the assembly of the fork 146.
La tige 148b porte, sur sa face supérieure, la règle 154, qui est avantageusement fixée par collage.The rod 148b carries, on its upper face, the rule 154, which is advantageously fixed by gluing.
La figure 11 permet de voir, de manière plus détaillée, le dispositif de mesure 20, ses curseurs 86, 88 et 90 et ses palpeurs 92, 94, 95 et 96.FIG. 11 allows a more detailed view of the measuring device 20, its cursors 86, 88 and 90 and its probes 92, 94, 95 and 96.
Le palpeur 92, venu de matière avec le curseur 86, est comparable au palpeur 142 décrit en référence à la figure 9, l'arête étant toutefois orientée vers le bas.The probe 92, formed integrally with the cursor 86, is comparable to the probe 142 described with reference to FIG. 9, the edge being however oriented downwards.
Comme expliqué plus haut, le curseur 88 porte deux palpeurs 94 et 95. Le palpeur 94 est une tige comparable à celle formant le palpeur 96. Elle est toutefois disposée sur le curseur 88 de manière à ce qu'elle soit orientée parallèlement à l'axe C-C.As explained above, the cursor 88 carries two feelers 94 and 95. The feeler 94 is a rod comparable to that forming the feeler 96. It is however placed on the cursor 88 so that it is oriented parallel to the CC axis.
Le palpeur 95 comporte un tube 158 orienté parallèlement à l'axe A-A et fixé sur le curseur 88 au moyen d'une clé non visible sur le dessin. Le tubeThe probe 95 comprises a tube 158 oriented parallel to the axis A-A and fixed on the cursor 88 by means of a key not visible in the drawing. The tube
158 porte une graduation qui n'a pas été représentée au dessin et qui permet de mesurer certaines cotes, comme cela sera expliqué plus loin. Une fourche 160, formée d'un bras 160a engagé dans le tube 158 et d'une pièce en U 160b, chacune des extrémités du U étant munie de deux doigts 160c, disposés de manière à ce que les doigts 160c puissent s'engager contre le tube de guidon, de part et d'autre de la potence. Le bras 160a est muni d'un plat orienté vers le haut, sur lequel une réglette 162 est fixée.158 carries a graduation which has not been shown in the drawing and which makes it possible to measure certain dimensions, as will be explained below. A fork 160, formed of an arm 160a engaged in the tube 158 and of a U-shaped part 160b, each of the ends of the U being provided with two fingers 160c, arranged so that the fingers 160c can engage against the handlebar tube, on both sides of the stem. The arm 160a is provided with a dish oriented upwards, on which a strip 162 is fixed.
Pour faire un bon usage du banc tel qu'il vient d'être décrit, il est, en outre, nécessaire de disposer d'un niveau électronique, de type permettant de déterminer les angles en fonction de l'horizontale. Ce niveau peut être de n'importe quel type disponible dans le commerce.To make good use of the bench as just described, it is, moreover, necessary to have an electronic level, of the type making it possible to determine the angles as a function of the horizontal. This level can be of any commercially available type.
La première opération consiste à ajuster la table 10. A cet effet, le niveau est placé sur la baguette 26 et le châssis 28 est mis de niveau de manière à ce que la table soit parfaitement horizontale. Dans cette position les hampes 12 et 14 sont, par construction, verticales.The first operation consists in adjusting the table 10. For this purpose, the level is placed on the rod 26 and the frame 28 is leveled so that the table is perfectly horizontal. In this position the stems 12 and 14 are, by construction, vertical.
Les supports 16 et 18 sont agencés de manière à ce que, lorsque l'arbre 46 du support 16 soit engagé dans le trou 44a, il se trouve à la même distance de la table 10 que les goupilles 54 du support 18. En d'autres termes, un plan passant par les axes de l'arbre 46, engagé dans le trou 44a, et des goupilles 54 est horizontal, puisque parallèle à la surface de la baguette 26.The supports 16 and 18 are arranged so that, when the shaft 46 of the support 16 is engaged in the hole 44a, it is at the same distance from the table 10 as the pins 54 of the support 18. By d ' in other words, a plane passing through the axes of the shaft 46, engaged in the hole 44a, and of the pins 54 is horizontal, since it is parallel to the surface of the rod 26.
Le vélo peut ensuite être est placé sur le banc, comme représenté sur la figure 2. Plus précisément, les clés 42 sont desserrées, de manière à ce que les supports 16 et 18 puissent être déplacés sur la table 10. La fourche 2 est montée sur le support 16 par ses extrémités, qui sont agencées pour recevoir le moyeu de la roue avant, l'arbre 46 jouant le rôle de ce dernier.The bicycle can then be placed on the bench, as shown in FIG. 2. More specifically, the keys 42 are loosened, so that the supports 16 and 18 can be moved on the table 10. The fork 2 is mounted on the support 16 by its ends, which are arranged to receive the hub of the front wheel, the shaft 46 playing the role of the latter.
De même, le cadre est ajusté sur le support 18 par ses organes destinés à recevoir le moyeu de la roue arrière. Il est fixé sur les goupilles 54, la position du sélecteur 52 étant choisie de manière à ce que les portées 54c permettent de positionner le cadre 1 sur son support. S'il est prévu que la roue avant du vélo soit de même diamètre que la roue arrière, l'arbre 46 est engagé dans le trou 44a. De la sorte, le vélo se trouve dans une position correspondant à celle qu'il aurait sur une route plate et horizontale.Similarly, the frame is adjusted on the support 18 by its members intended to receive the hub of the rear wheel. It is fixed to the pins 54, the position of the selector 52 being chosen so that the bearing surfaces 54c make it possible to position the frame 1 on its support. If it is expected that the front wheel of the bicycle is the same diameter as the rear wheel, the shaft 46 is engaged in the hole 44a. In this way, the bicycle is in a position corresponding to that which it would have on a flat and horizontal road.
Si la roue avant était de diamètre plus faible que la roue arrière, cette différence serait compensée en choisissant l'un des trous 44b à 44d, de manière à ce que le vélo se trouve également dans une position correspondant à celle qu'il aurait sur une route plate et horizontale.If the front wheel was smaller in diameter than the rear wheel, this difference would be compensated for by choosing one of the holes 44b to 44d, so that the bicycle is also in a position corresponding to that which it would have on a flat, horizontal road.
Le dispositif de mesure 20 est ensuite ajusté au vélo. A cet effet, la molette 68 est desserrée, de manière à pouvoir glisser le patin 62 sur la table 10. Le bras 64 est ensuite réglé de manière à ce que le trou 72e se trouve en regard du support de pédalier le. Le goujon 78 peut alors être engagé dans le trou 72e et dans le support de pédalier le, la clé 80 étant ensuite serrée, de manière à ce que le goujon 78 soit fixé rigidement à la plaquette de pédalier. Le goujon 78 est dimensionné de manière à ce qu'il puisse pivoter librement dans le support de pédalier le, avec un minimum de jeu.The measuring device 20 is then adjusted to the bicycle. To this end, the thumbwheel 68 is loosened, so that the shoe 62 can slide on the table 10. The arm 64 is then adjusted so that the hole 72e is located opposite the bottom bracket le. The stud 78 can then be engaged in the hole 72e and in the bottom bracket the, the key 80 is then tightened, so that the stud 78 is rigidly fixed to the bottom bracket. The stud 78 is dimensioned so that it can pivot freely in the bottom bracket the, with a minimum of play.
Le niveau est ensuite appliqué contre le bras 64, pour placer ce dernier verticalement. Lorsque ce réglage est fait, les molettes 68 et 76 sont serrées.The level is then applied against the arm 64, to place the latter vertically. When this adjustment is made, the knobs 68 and 76 are tightened.
Les plots 122 sont ensuite réglés de manière à ce qu'ils se trouvent à une même hauteur, arbitraire, par exemple 300 mm, mesurée sur les règles 34, puis fixés par serrage des clés 126. Le barreau 110 est ensuite mis en place sur les plots 122, au moyen des clés 128. Il est parallèle à la table 10 si les deux hauteurs des plots 122 sont égales. Cela revient à dire que le barreau 110 est horizontal. La hauteur de l'axe du pédalier HB peut alors être déterminer en soustrayant à la hauteur des plots 122, lue sur la règle 34, la valeur lue sur la règle 82, à son croisement avec le barreau 110. L'opération suivante consiste à vérifier l'inclinaison TV du tube montant la ainsi que la hauteur de la selle 5. Cette dernière est engagée dans le tube montant la avec un serrage permettant de la déplacer sans effort.The studs 122 are then adjusted so that they are at the same height, arbitrary, for example 300 mm, measured on the rules 34, then fixed by tightening the keys 126. The bar 110 is then placed on the studs 122, by means of the keys 128. It is parallel to the table 10 if the two heights of the studs 122 are equal. This amounts to saying that the bar 110 is horizontal. The height of the BB pedal axis can then be determined by subtracting from the height of the studs 122, read on rule 34, the value read on rule 82, at its crossing with the bar 110. The following operation consists in checking the inclination TV of the riser tube la as well as the height of the saddle 5. The latter is engaged in the riser tube la with a tightening allowing it to be moved effortlessly.
Le dispositif de mesure est incliné de manière à ce qu'il soit orienté parallèlement au tube de selle la. Le curseur 88 est déplacé sur la barre 74, jusqu'à ce que le palpeur 94 se trouve à la hauteur de selle théorique HS. Cette lecture se fait sur la règle 82. Plus précisément, la valeur lue est égale à la hauteur de selle HS moins la longueur des manivelles du pédalier 7 qui est mesurée par ailleurs. La selle 5 est ensuite amenée en contact avec le palpeur 94.The measuring device is inclined so that it is oriented parallel to the seat tube la. The cursor 88 is moved on the bar 74, until the probe 94 is at the theoretical saddle height HS. This reading is done on rule 82. More specifically, the value read is equal to the seat height HS minus the length of the cranks of the pedal unit 7 which is measured elsewhere. The saddle 5 is then brought into contact with the probe 94.
L'inclinaison du tube montant TV peut être vérifiée soit en utilisant le niveau, soit par trigonométrie.The inclination of the TV riser can be checked either by using the level or by trigonometry.
Si la valeur mesurée est différente de la valeur théorique, le dispositif de mesure est amené dans la position théorique, et la selle est déplacée vers l'avant ou vers l'arrière, selon la correction effectuée. De la sorte, bien que le cadre ne corresponde pas parfaitement à l'inclinaison théorique, le déplacement de la selle 5 selon une direction parallèle à l'axe A-A permet de corriger ce défaut. La correction ne doit, toutefois pas dépasser certaines limites, fonction du poids de l'utilisateur, à cause du couple que subit la selle, le poids de l'utilisateur n'étant plus appliqué directement sur le tube de selle. Si nécessaire, la hauteur de selle HS peut encore être ajustée.If the measured value is different from the theoretical value, the measuring device is brought into the theoretical position, and the saddle is moved forwards or backwards, depending on the correction made. In this way, although the frame does not correspond perfectly to the theoretical inclination, the displacement of the saddle 5 in a direction parallel to the axis A-A makes it possible to correct this defect. The correction must not, however, exceed certain limits, depending on the weight of the user, because of the torque experienced by the saddle, the weight of the user no longer being applied directly to the seat tube. If necessary, the HS seat height can be further adjusted.
Le réglage de la position du guidon, et tout particulièrement de la hauteur de potence HG, est réalisé en plaçant la traverse 22 de manière à ce qu'elle corresponde à la hauteur théorique HC du cadre. A cet effet, le dispositif de mesure 20 est maintenu dans sa position faisant un angle TV avec l'horizontale et le curseur 88 est déplacé sur la barre 74 jusqu'à la cote correspondant à HC. La traverse 22 est ensuite déplacée vers le haut sur les mâts 32, de manière à ce qu'elle vienne prendre appui contre le palpeur 94. Elle est ainsi à la hauteur voulue. La traverse 22 est ensuite ajustée selon une direction parallèle à l'axe A-A, de manière que l'origine de la règle 120 se trouve en regard de l'extrémité conique du palpeur 94.The adjustment of the position of the handlebars, and in particular of the height of the stem HG, is carried out by placing the cross-member 22 so that it corresponds to the theoretical height HC of the frame. To this end, the measuring device 20 is kept in its position making an angle TV with the horizontal and the cursor 88 is moved on the bar 74 to the dimension corresponding to HC. The crosspiece 22 is then moved upwards on the masts 32, so that it comes to bear against the probe 94. It is thus at the desired height. The cross-member 22 is then adjusted in a direction parallel to the axis AA, so that the origin of the rule 120 is opposite the conical end of the probe 94.
La suite de la description fait référence à la figure 8. L'outil de mesure 130 est ensuite réglé de manière à ce que la barre 138 fasse avec l'horizontale un angle égal à celui TD du tube de direction. Il est placé sur le barreau 110 à la cote égale à la longueur de cadre LC. Le curseur 140 est déplacé sur la barre 138 jusqu'à une hauteur correspondant à la hauteur HG de la potence 4. La fourche 146 est amenée en appui sur l'arête 142a du palpeur 142. De la sorte, la face supérieure du doigt inférieur 150c se trouve à la hauteur voulue. Les curseurs 117 et 118 et les outils de mesure 130 et 132 sont verrouillés. En desserrant les clés 128, il est possible de déplacer selon l'axe A-A le barreau 110, tout en faisant coulisser la potence 4 dans le tube lb, jusqu'à pouvoir insérer le guidon 3 entre les doigts 150b et 150c, comme représenté sur la figure 8. Le guidon 3 se trouve alors à la bonne hauteur. Le point d'intersection de la barre 138 avec le bras 148 permet de lire, sur la règle 154 la longueur de potence LP. La lecture est facilitée du fait que l'arête 142a du palpeur 142 se trouve en regard de la règle 154.The following description refers to FIG. 8. The measurement tool 130 is then adjusted so that the bar 138 makes an angle with the horizontal equal to that TD of the steering tube. It is placed on the bar 110 at the level equal to the length of the LC frame. The cursor 140 is moved on the bar 138 to a height corresponding to the height HG of the bracket 4. The fork 146 is brought to bear on the edge 142a of the probe 142. In this way, the upper face of the lower finger 150c is at the desired height. The cursors 117 and 118 and the measurement tools 130 and 132 are locked. By loosening the keys 128, it is possible to move the bar 110 along the axis AA, while sliding the stem 4 in the tube lb, until the handlebar 3 can be inserted between the fingers 150b and 150c, as shown in Figure 8. The handlebar 3 is then at the right height. The point of intersection of the bar 138 with the arm 148 makes it possible to read, on the rule 154, the length of the stem LP. Reading is facilitated by the fact that the edge 142a of the probe 142 is located opposite the rule 154.
Les opérations suivantes, expliquées en référence à la figure 11, permettent de déterminer le retrait de selle RS et la distance selle-guidon SG. Pour ce faire, le dispositif de mesure 20 est à nouveau placé verticalement, le réglage étant effectué au moyen du niveau. Le curseur 88 est amené à la hauteur de la selle 5, puis le tube 158 y est introduit, de sorte qu'en le glissant, il vienne prendre appui par son extrémité contre la pointe de la selle 5. Le tube est ensuite bloqué au moyen de la clé non visible au dessin. La graduation que porte le tube 158 permet alors de lire la valeur du retrait de selle RS. La fourche 160 est ensuite introduite dans le tube 158 et le curseur ajusté en hauteur sur la barre 74 de manière à ce que les doigts 160c s'engagent de part et d'autre du tube horizontal du guidon 3 et que la pièce en U 160b soit en butée contre ce tube. Il est alors possible de lire la distance selle-guidon SG sur la réglette 162.The following operations, explained with reference to FIG. 11, make it possible to determine the saddle retraction RS and the saddle-to-handlebar distance SG. To do this, the measuring device 20 is again placed vertically, the adjustment being carried out by means of the level. The cursor 88 is brought to the height of the saddle 5, then the tube 158 is introduced therein, so that by sliding it, it comes to bear by its end against the tip of the saddle 5. The tube is then blocked at using the key not visible in the drawing. The graduation carried by the tube 158 then makes it possible to read the value of the saddle shrinkage RS. The fork 160 is then introduced into the tube 158 and the cursor adjusted in height on the bar 74 so that the fingers 160c engage on either side of the horizontal tube of the handlebar 3 and that the U-shaped part 160b is in abutment against this tube. It is then possible to read the saddle-to-handlebar distance SG on the strip 162.
Il ressort de la description ci-dessus que le banc tel qu'il vient d'être décrit permet, de par son principe, de régler pratiquement tous les paramètres du vélo assemblé et/ou contrôlé. Il est évident que la mesure des différents paramètres du vélo peut être envisagée sur la base d'autres structures similaires, sans pour autant sortir du cadre de l'invention.It emerges from the above description that the bench as just described allows, by its principle, to adjust practically all the parameters of the assembled and / or controlled bicycle. It is obvious that the measurement of the various parameters of the bicycle can be envisaged on the basis of other similar structures, without however departing from the scope of the invention.
Il est ainsi possible de remplacer les règles par des lecteurs optiques et effectuer l'ensemble des mesures par des moyens électroniques.It is thus possible to replace the rules with optical readers and carry out all of the measurements by electronic means.
Il est également possible d'intégrer des rapporteurs d'angles ou des niveaux, par exemple dans la table 10, la traverse 22 ou le dispositif de mesure 20, de manière qu'il ne soit pas nécessaire de faire appel à un outil indépendant du banc.It is also possible to integrate reporters of angles or levels, for example in the table 10, the crosspiece 22 or the measuring device 20, so that it is not necessary to use a tool independent of the bench.
Il est de plus possible d'optimiser un vélo existant de manière à ce qu'il soit le mieux adapté possible à l'utilisateur, sans pour autant apporter de modifications importantes au vélo, par exemple en adaptant la selle 5 ou en changeant de potence 4. It is also possible to optimize an existing bicycle so that it is the best possible fit for the user, without making significant modifications to the bicycle, for example by adapting the saddle 5 or by changing the stem. 4.
