Description

DESCRIPTION DESCRIPTION
ROUE DE BICYCLETTEBICYCLE WHEEL
La présente invention concerne une roue de bicyclette.The present invention relates to a bicycle wheel.
De façon connue une roue avant ou arrière de bicyclette comprend une jante, un moyeu central, ainsi qu'une liaison entre la jante et le moyeu qui peut être réalisée par des nappes de rayons, des bâtons ou bien une carcasse pleine (roue lenticulaire) . La jante étant conçue pour accueillir un pneu tubulaire (ou boyau) , un pneu tubeless, ou un pneu et sa chambre à air .In a known manner, a front or rear bicycle wheel comprises a rim, a central hub, as well as a connection between the rim and the hub which can be produced by plies of spokes, sticks or else a full carcass (lenticular wheel) . The rim being designed to accommodate a tubular tire (or tubular), a tubeless tire, or a tire and its inner tube.
Un but de l'invention est de proposer une roue ne nécessitant plus le montage d'un pneumatique, mais simplement la pose d'une bande de roulement montée serrée ou collée directement sur la jante ; ceci permettant de résoudre le problème des crevaisons, mais aussi d'améliorer l'interchangeabilité des bandes de roulement afin d'utiliser différents types de gomme selon la pratique et le terrain rencontré.An object of the invention is to provide a wheel no longer requiring the mounting of a tire, but simply the fitting of a tread mounted tight or glued directly to the rim; this makes it possible to solve the problem of punctures, but also to improve the interchangeability of the treads in order to use different types of rubber depending on the practice and the terrain encountered.
Un autre but de l'invention est d'améliorer les qualités de relance d' une bicyclette en diminuant le diamètre de contact avec la route par rapport à une roue, équipée de pneumatique classique, ayant le même diamètre de portée de patins de frein. La roue se trouvant ainsi allégée dans sa partie la plus éloignée de - l'axe de rotation, ce qui diminue son inertie. D'autre part la carcasse de cette jante et de sa bande de roulement présente une rigidité supérieure à un montage classique sur un pneumatique, cela permettra d'améliorer le rendement de la roue.Another object of the invention is to improve the recovery qualities of a bicycle by reducing the diameter of contact with the road with respect to a wheel, fitted with conventional tires, having the same bearing pad diameter. The wheel thus being lightened in its part farthest from - the axis of rotation, which reduces its inertia. On the other hand the carcass of this rim and its tread has a rigidity greater than a conventional mounting on a tire, this will improve the efficiency of the wheel.
Il est bien entendu que l'invention reste valable pour tout type d'accrochage de la jante au moyeu. Cependant elle est présentée dans une configuration de liaison par écrous et rayons. La particularité de cette invention est d'avoir disposée les deux nappes de rayon de façon symétrique par rapport au plan médian de la jante ainsi les rayons sont directement opposés deux à deux et permettent d'améliorer l'équilibre des tensions dans ces rayons, mais aussi de faciliter le dévoilage de la jante .It is understood that the invention remains valid for any type of attachment of the rim to the hub. However, it is presented in a connection configuration by nuts and spokes. The characteristic of this invention is to have arranged the two plies of radius symmetrically with respect to the median plane of the rim so the spokes are directly opposite two by two and allow to improve the balance of tensions in these spokes, but also to facilitate the unveiling of the rim.
L'invention sera détaillée dans la description qui suit et illustrée par les dessins en annexe. La figure n°l représente une vue axonométrique de la roue complète dans un premier mode d'accrochage des rayons.The invention will be detailed in the following description and illustrated by the accompanying drawings. FIG. 1 represents an axonometric view of the complete wheel in a first mode of attachment of the spokes.
La figure n°2 représente une coupe partielle de la figure n°l en vue axo.nométrique .Figure 2 shows a partial section of Figure 1 in axo.nometric view.
La figure n°3 représente une section transversale de la jante, de la bande de roulement, des écrous et rayons dans le premier mode d'accrochage.Figure 3 shows a cross section of the rim, the tread, the nuts and spokes in the first attachment mode.
La figure n°4 représente la jante de la figure n°3 et son moyeu .Figure 4 shows the rim of Figure 3 and its hub.
La figure n°5 représente une vue axonométrique de la roue complète dans un deuxième mode d'accrochage des rayons.FIG. 5 represents an axonometric view of the complete wheel in a second mode of attachment of the spokes.
La figure n°6 représente une coupe partielle de la figure n°5 en vue axonométrique.Figure 6 shows a partial section of Figure 5 in an axonometric view.
La figure n°7 représente une section transversale de la jante, de la bande de roulement, d'un obturateur, des écrous et rayons dans le deuxième mode d'accrochage.Figure 7 shows a cross section of the rim, the tread, a shutter, the nuts and spokes in the second attachment mode.
La roue représentée dans les figures n°l, 2, 3, 4 comporte une jante (1), sa bande de roulement (2), un moyeu central (7) relié à la jante par deux nappes de rayons (5), (6) et leurs écrous (3) , (4) . La figure n°3 représente une section de la jante selon un premier mode d'accrochage des rayons.The wheel shown in Figures 1, 2, 3, 4 has a rim (1), its tread (2), a central hub (7) connected to the rim by two plies of spokes (5), ( 6) and their nuts (3), (4). Figure 3 shows a section of the rim according to a first mode of attachment of the spokes.
La jante est formée de deux parois latérales (8), (9) servant de zone de portée des patins de frein et reliant le pont inférieur (13) au pont supérieur (12) qui sert également de support à la bande de roulement (2), celle-ci étant positionnée par les deux épaulements (10) , (11) . La section de la jante est entièrement fermée et ne permet pas la mise en place des écrous de fixation (3), (4) des rayons (5), (6), ce qui explique la présence de pontets composés de deux parois de liaison (14), (15) et d'une surface (16) d'accrochage percée de deux trousThe rim is formed by two side walls (8), (9) serving as a bearing area for the brake pads and connecting the lower bridge (13) to the upper bridge (12) which also serves as a support for the tread (2 ), the latter being positioned by the two shoulders (10), (11). The rim section is fully closed and does not allow the fitting of the fixing nuts (3), (4) of the spokes (5), (6), which explains the presence of bridges composed of two connecting walls (14), (15) and a hooking surface (16) pierced with two holes
(17), (18) servant de logement aux écrous (3), (4). Cette fixation entre la jante et le moyeu par deux nappes de rayons symétriques par rapport au plan médian de la roue et un accrochage par pontets peut évidemment s'appliquer à tout type de jante et de moyeu. La roue représentée dans les figures n°5, 6, 7 comporte une jante (20), sa bande de roulement (2), un moyeu central (7), relié à la jante par deux nappes de rayons (24), (25) et leurs écrous (22) , (23) .(17), (18) serving as a housing for the nuts (3), (4). This fixing between the rim and the hub by two plies of spokes symmetrical with respect to the median plane of the wheel and attachment by bridges can obviously be applied to any type of rim and hub. The wheel shown in Figures 5, 6, 7 has a rim (20), its tread (2), a central hub (7), connected to the rim by two plies of spokes (24), (25 ) and their nuts (22), (23).
La figure n°7 représente une section de la jante selon un deuxième mode d'accrochage des rayons.Figure 7 shows a section of the rim according to a second method of hooking the spokes.
La jante est formée de deux parois latérales (32), (33) servant de zone de portée des patins de frein et reliant le pont supérieur (34) au pont inférieur (28). Le pont supérieur (34) sert de support à la bande de roulement (2) qui est positionnée par les deux épaulements (30), (31), de plus il est percé de trous (29) qui servent de passage aux écrous (22), (23). Une fois les écrous mis en place, des obturateurs (21) sont montés afin de reconstituer le galbe supérieur de la jante (20) . Le pont inférieur (28) est, dans cette version, percé de trous (26), (27) qui servent de logement aux écrous (22), (23). La fixation entre la jante et le moyeu est présentée dans une version à deux nappes de rayons disposées symétriquement par rapport au plan médian de la roue, mais il est évident que l'invention reste valable quelle que soit l'inclinaison des parapluies des deux nappes de rayons.The rim is formed by two side walls (32), (33) serving as a bearing area for the brake pads and connecting the upper bridge (34) to the lower bridge (28). The upper bridge (34) serves as a support for the tread (2) which is positioned by the two shoulders (30), (31), moreover it is pierced with holes (29) which serve as passage for the nuts (22 ), (23). Once the nuts are in place, shutters (21) are fitted in order to reconstitute the upper curve of the rim (20). The lower bridge (28) is, in this version, pierced with holes (26), (27) which serve as housing for the nuts (22), (23). The attachment between the rim and the hub is presented in a version with two plies of spokes arranged symmetrically with respect to the median plane of the wheel, but it is obvious that the invention remains valid regardless of the inclination of the umbrellas of the two plies of rays.
De plus la forme du profil de la jante n'est pas limitative, le pont supérieur peut avoir une courbure autre qu'un arc de cercle et le pont inférieur peut ne pas être matérialisé dans le cas, par exemple, d'une jante à profil triangulaire. Enfin l'invention s'applique à tous types de roue avant ou arrière associé à tous les systèmes de freinage, à patins, à disques, à tambour ou autre. In addition, the shape of the rim profile is not limiting, the upper bridge may have a curvature other than an arc of a circle and the lower bridge may not be materialized in the case, for example, of a rim with triangular profile. Finally, the invention applies to all types of front or rear wheel associated with all braking systems, pads, discs, drums or the like.
