Definitions

• the present invention relates to a wheel for a bicycle or other similar vehicles, which comprises a rim connected to a hub by means of a set of spokes that converge in pairs on two flanges, one on either side of the hub. It is characterised in that in each of the consecutive pairs of spokes, the first one is connected to the flange on the left- hand side, the second to the flange on the right-hand side, the third to the flange on the right-hand side and the fourth to the flange on the left-hand side, this arrangement making it possible to balance the tension in each pair of spokes exerted between the rim and the hub.
• bicycle wheels have a rim that is connected to the hub by means of spokes . According to the conventional arrangement of the spokes, they are generally equidistant from each other.
• Document WO 02/053395 relates to a bicycle wheel, particularly for racing and mountain bicycles, comprising a rim that is coaxially connected to a hub by means of a set of spokes which converge on a pair of flanges that are coaxial to the hub, the flanges having coupling projections distributed in the peripheral zone of the flanges and containing tangential coupling holes, with one end of the spokes fitting into the holes and the other end connected to tips designed to couple with the rim.
• Document FR 2 640 203 relates to a device for fixing spokes on to the hub of a bicycle wheel or wheel of similar vehicles, characterised in that the flanges, particularly of the hub, are arranged so that after each of the pairs of spokes are fixed, the spokes of a same pair are arranged in two diametrically opposite directions so as to exert on the hub two opposite tension forces the result of which is zero or substantially zero.
• Patent US 478 394 relates to a bicycle wheel characterised by the combination of a hub with a set of independent projections forming part of the hub and projecting radially therefrom, each of the said projections having flat holes with spokes inserted in said holes and arranged tangentially to the hub, said spokes having at each of their inside ends heads that rest against the side wall of the projections, the outer ends of the spokes being fixed to the wheel rim, substantially as previously described.
• each of the projections being one of a set of projections arranged alternately on one side of the circumferential line of the sets of adjacent projections, each one of the projections having flat holes and spokes arranged tangentially to the hub, inserted in said holes and having at or near to their inside ends heads that rest against the side wall of the projections, substantially as previously described.
• This invention relates essentially to a new bicycle wheel where the spokes are arranged in pairs between the rim and the hub, the spokes of each pair of spokes being fixed alternately, one to one of the flanges and the other to the flange on the other side of the hub.
• FIG. 1 represents a perspective view of the wheel of the invention
• Figure 2 represents a main elevation of the same wheel ;
• FIG. 3 represents a perspective view of the wheel hub
• FIG. 6 represents a side elevation and cross-section along the line B of figure 5 of the wheel hub
• Figures 7 and 8 represent in schematic form the arrangement of the spokes of the document WO 02/053395 and the arrangement of the spokes of this invention respectively.
• the bicycle wheel consists of a rim 3 with 24 holes arranged in pairs and the corresponding 24 spokes 1.
• the holes in the rim 3 must comply with certain requirements substantiated by the logical term a > b, a being the distance between the spokes of adjacent pairs and b the distance between adjacent spokes of the same pair b.
• the hub 2 (figures 3 to 6) has a pair of flanges 4 and 5, one on each side of the hub, with holes (see figure 6) aligned in a circle between the two flanges.
• the said spokes 1 converge in pairs on two flanges 4 and 5, one on each side of the hub 2, connected coaxially to the said hub.
• the first one is connected to the flange on the left-hand side 4, the second to the flange on the right-hand side 5, the third to the flange on the right-hand side 5 and the fourth to the flange on the left-hand side.
• This arrangement of the spokes makes it possible to balance the tension that in each pair of spokes is exerted between the rim 3 and the hub 2'.
• the alternating arrangement of the spokes can be applied with any type of spokes and with any tightening heads, which should only be appropriate for the force that they will exert, and this arrangement can be applied to a front or a rear wheel . It should also be noted that this arrangement can be applied to any rim profile.
