    [0001] FIELD OF THE INVENTION The present invention relates to the field of cycles and more particularly to the rapid attachment assemblies of a cycle wheel to a cycle frame fork. It will find for particular application sets of fixing of road bike wheels and mountain bike. The invention relates to a fastening assembly, a spindle and a hub for such a system and a wheel and a cycle equipped with such a hub and such an assembly. In a known manner, a cycle wheel comprises a hub, a rim intended to receive a tread and spokes or discs providing the mechanical connection between the hub and the rim. The hub comprises a hub body configured to be attached to the spokes or disks and a hub shaft providing the mechanical connection of the hub with a front or rear fork of a cycle frame. The fork usually comprises two attachment tabs which each attach to one end of the hub shaft. The latter is fixed in rotation when the rim rotates. For a sport of cycling, it is necessary to be able to detach quickly and without tools the wheel and fork so you can for example quickly troubleshoot a cyclist who has suffered a puncture or simply to facilitate transportation or storage of the bike. Several solutions have been proposed to achieve rapid attachment of the wheel to the fork. These solutions all rely on the use of a spindle that passes through the hub shaft, with each end of the hub, one end of the spindle protruding. Each end of the spindle cooperates with one of the attachment tabs of the fork 30 to allow attachment of the spindle on the fork in locked configuration and to allow removal of the fork spindle in unlocked configuration. A first solution consists in inserting each end of the pin into one of the two bores carried by the fixing lugs. EP0810944 describes this type of solution. Each bore of the fastening tabs has a passage slot communicating the bore with the outside and allowing insertion of the bore spindle by making a movement through the passage slots. This movement is a mainly vertical movement when the cycle is in rolling configuration. A disadvantage of this type of solution is that in case of poor clamping of the spit on the fork, the spindle can exit the bores through the passage slots. The wheel can then disengage from the frame during the driving phase which can lead to a fall with dramatic consequences.
    [0002] To improve the safety of the cyclist, another solution provides fastening tabs on the fork whose bores are closed, that is to say that they do not include a passage slot. It is therefore necessary to insert the pin through these bores in a direction corresponding to the axis of rotation of the wheel. One of the bores forms a tapping inside which is screwed a threaded end of the spindle. This solution is satisfactory in terms of security. On the other hand, it has the disadvantage of having to completely remove the spindle of the motor during a wheel change, which is long and tedious. To remedy this drawback, another solution such as that described in document US Pat. No. 6,089,675 provides for a fork whose first fastening lug comprises a tapped bore without passage slot and a second fixing lug comprising a non-threaded bore continuing vertically. by a slot of passage. It is thus possible to bring the assembly (the hub and the spindle) opposite the two bores by passing the spindle through the passage slot of the second bore and then by moving along the axis of the spindle to engage the end. Threaded spindle with tapped bore of the first bracket. This document describes several embodiments where the spindle is urged axially by a spring in order to pre-engage the threaded end of the spindle in the tapping of the first bore. Document US 2013/0270893 describes an improvement of the previous document 25 by adding an axial indexing system of the spindle so that this spindle has a stable open position despite the axial thrust of the return spring. These solutions have the disadvantage of preventing or making very complex extraction of the pin out of the hub. However this extraction is necessary to ensure the cleaning of these organs essential to the performance of the cycle or to change wheels while maintaining the same pin. These solutions also have a very specific hub design that does not make them compatible with the existing spindles on the market, so a wheel of this type can not be installed on a bike with a standard spindle fork with two closed bores (without slot). This disadvantage of incompatibility greatly limits the adoption of this concept from the final cyclist through the distribution network to the hub manufacturer. In addition, the handling of the spindle is complex. There is therefore a need to provide a solution to overcome some of the disadvantages mentioned above. 3037919 3 It would be particularly advantageous to have a solution, robust, reliable and economical to reduce or even avoid the risk of unintentional dropout of the wheel while allowing easy disassembly thereof, an easy extraction the spindle out of the hub and an inter-compatibility of this hub 5 with existing forks and pins already on the market. DESCRIPTION OF THE INVENTION The object of the invention is achieved by providing a pin for attaching a wheel to a cycle type vehicle, comprising a rod which extends along a longitudinal axis, a first end which comprises means cooperating with the frame of said vehicle and a second end which comprises means capable of exerting a tightening torque, in which: said rod comprises a groove whose extension along said longitudinal axis has a length L1, an element of variable diameter and length L2, the length L2 being smaller than L1, is received in the groove so as to be able to move in translation along the longitudinal axis, - an elastic means longitudinally constrained said element of variable diameter in the direction from the second end.

The object of the invention is also achieved by the provision of an assembly consisting of a spindle having the characteristics mentioned in the preceding five paragraphs and a hub of a vehicle wheel, said hub comprising a hollow shaft, of which at least one portion has an inner diameter D3 and the other portions have an inner diameter greater than D3 and a hub body rotatably mounted on the shaft; characterized in that the diameter D3 is greater than the maximum diameter of the rod D1 and D3 is smaller than the diameter D2 of the ring in the free state.

Detailed Description A first embodiment of the present invention will now be Referring to FIGS. 1 to 6, FIG. 1 shows the fork arms and the attachment lugs 100a, 100b of a frame fork. The bracket 100a has at its end a bore 101a. This bore 101a is closed, that is to say that its periphery has no opening. It is preferably tapped. The bracket 100b has a bore 101b whose periphery is open by a through slot 105. The width of the slot 105 is smaller than the diameter of the bore 101b so that the slot constitutes a narrowing of the slot. bore. The hub 200 has a hub body 210 having two flanges 211 having a plurality of housings 212 for unrepresented spoke heads. The remainder of the cycle wheel, namely spokes, rim, tire, are also not shown. The hub 200 also comprises a hub shaft 220 housed in the hub body 210 and intended to be fixed on the fork. When the wheel is fixed, the shaft 220 is immobilized in translation and in rotation relative to the fork. Thus, the hub body 210 rotates on the hub shaft 220 about an axis 11 referenced in FIG. 2. The hub shaft 220 has an internal passage 222 which preferably extends over its entire length and which is configured to be traversed by pin pin 310. Pin pin 310 includes an end 314 configured to penetrate bore 101a. Preferably, this end 314 is threaded and is screwed into the tapping of the bore 101a. The first threads from the end were truncated to form a threaded end. Pin 310 comprises on its outer surface several portions 315, 316, 317, 318, 319 which will be described later. The end of the rod 310 opposite the threaded end 314 is configured to penetrate the bore 101b, preferably through the passage slot 105 as will be described in detail later. This end is associated with a handle 370 intended to be operated, for example pushed, rotated, pulled by the user to respectively engage the pin of the bore 101a, screw it into the bore 101a or remove it from the fork. The spindle comprises a groove 318 which extends along the longitudinal axis along a length L1. This groove 318 receives, a member of variable diameter, which takes, in this embodiment, the form of a split tubular ring 320; an elastic means, in the form of a spring 330 and a distribution ring 340 which is inserted between the two previous elements. As can be seen in Figure 4a, the bottom of the groove does not have an identical diameter along the entire length thereof. Different sections of the groove 10 are thus defined. Starting from the end of the groove which is closest to the end 314 of the spindle, there is a centering section 3181 of the spring, a sliding section 3182 of the distribution ring 340 and a centering section 3183 In the embodiment described here, the pin shaft is made of a single block, so that it is necessary to provide a slot 341 in the distribution ring to allow mounting. . Preferably one will choose a distribution ring with a slot whose orientation is a non-zero angle with the axis 11. Thus the deformation of the ring during assembly is less likely to damage by plasticizing. For the same reasons of assembly, a spring will be chosen whose mechanical properties allow it a radial expansion sufficient to pass over portions of the rod which have an outside diameter greater than the diameter of the spring. Other embodiments, not described here, comprise a spindle rod made of at least two pieces with an interface between the two pieces passing through the groove 318. The placement of the different elements in the groove then raises 25 no problem and one can use a distribution ring and a spring non-deformable radially. These embodiments may include in particular two pieces screwed, locked and possibly glued one into the other while ensuring that the unscrewing can occur during use. The distribution ring 340 comprises a centering portion of the spring 342 and an abutment portion 343, on which the tubular ring bears. In the first embodiment, the split tubular ring 320 has a length L2 of between 2 and 30 mm, preferably between 5 and 15 mm. Good results are obtained with a ring of 10 mm length. The outer diameter D2 of the tubular ring 320 is, in the free state, greater than the outer diameters of all the portions 315, 316, 317, 318 and 319 of the rod 310. In practice, the diameter of the portions 315, 317 and 319 is substantially identical and will be named D1. The diameter D1 corresponds to the maximum outside diameter of the rod 310.
    [0006] This ring can be obtained from a rolled steel sheet, preferably in a high tensile steel. It can also be in an aluminum alloy with high mechanical characteristics, such as 7075. Preferably, the front edges of the ring are tonnally radiated 5 to facilitate the insertion thereof into the internal passage 222, as we will see it later. The first fixing of the hub 200 of the wheel to the fork with the aid of the spindle according to the invention will now be described. Figure 2 illustrates in longitudinal section a phase of the first insertion of the spindle 300 into the hub 200. It may also be the re-insertion of the spindle 300 into the hub. Beforehand, the spindle was completely extracted from the hub. The user has placed the wheel in the correct location. The bearing surfaces of the hub 221a and 221b are in abutment respectively against the vertical stops 103a and 103b. The internal passage 222 of the hub shaft 220 is aligned with the bores 101a and 101b of the fastening lugs 100a and 100b. To be able to penetrate the spindle, the user exerts, in the direction of engagement 1, an axial force. It is through the bearing surfaces 221a, 221b and stops 103a, 103b that the weight of the cycle and the user is transmitted to the wheel. Thus, the pin 300 does not take 20 or very little of the vertical load, which does not interfere with its axial displacement and makes the whole more robust. The axial force exerted by the user must be sufficient to allow, on the one hand, to constrain the ring 320 to reduce its diameter and to slide it inside the internal passage. Indeed, the outer diameter of the ring, in the free state, D2 is greater than the inner diameter D3 of the internal passage 222 of the shaft 220. The ring generates a radial force distributed on the internal passage 222. The coefficient friction "f" between the ring and the internal passage 222 will allow to transmit an axial force Fa substantially proportional to the aforementioned radial force and the coefficient of friction between the ring and the internal passage. Thus, if one exerts a force lower than Fa, the ring remains motionless in the internal passage. The ring begins to move only when you exceed this threshold, in one direction as in the other. The internal passage and the ring having their own manufacturing tolerance, the insertion of the pin into the internal passage will induce a tightening of the ring (retraction of its outer diameter) variable. It is therefore necessary that the nominal tightening is well above the tolerance intervals. By way of example, for a hub whose internal diameter D3 of the internal passage varies between 12.02 and 12.12 mm, the maximum outside diameter of the rod D1 is dimensioned at 12.00 mm and that of the ring D2 is 12 , 45 and 12.55 mm. The maximum tightening is equal to 0.53 mm and the minimum tightening is 0.33 mm. The tightening variation is therefore in this case about + 1-25%, which is acceptable for the application. By choosing a steel ring with a diameter of 12.50 mm, a length of 10 mm and a thickness of 0.85 mm, the force Fa is approximately + 1-45 N depending on the direction of movement of the spindle. The force Fa is proportional to the length of the ring, the nominal clamping and the coefficient of friction. Fa = k. 1.2. The user exercises throughout this phase a thrust along the axis 11. Figure 3 illustrates in longitudinal section the end of the thrust phase. The tip 325 of the rod 320 is now inserted into the bore 101a. It will also be noted that the portion 315 is then already partially inserted in the bore 101b. The wheel is already trapped in the cycle. Indeed, as can be seen in Figure 3a, the diameter of the portion 315 is greater than the width of the passage slot 105. Therefore, although the fixing process is not completed, there is 15 in this state of first security. To finalize the process of fixing the wheel, the user exerts a torque in order to screw the threaded end 314 into the tapping of the bore 101a. Figure 4 illustrates the end of this screwing operation and the state of the spindle when the wheel is firmly attached to the frame of the cycle. FIG. 4a, which is a detail view of FIG. 4, shows what is the final position reached by the ring 320 after the first insertion of the spindle. As long as the pin 300 of the hub 200 is not completely removed, this position will not vary. Thus, during a simple disassembly of the wheel, the ring will maintain the same axial position relative to the hub. The ring is then in fact an axial abutment integral with the hub on which rests the spring which forces the pin towards its engagement in the fork leg. This axial abutment will not be affected as long as the axial force exerted on the spindle in the extraction direction 2 will not exceed the effort threshold Fa required to slide the ring. In the embodiment shown, the torque can be exerted manually by means of the pin handle 370 or by means of a key. A torque limiter such as that described in patent application EP 2,070,725 is disposed within the handle. We will now explain the process of disassembling and reassembling the wheel without complete extraction of the spindle. Disassembly begins with a loosening operation of the spindle. At the end of this operation, the spindle is found in the position described in FIG. 3, with the exception of the ring 320 which is not the position of FIG. 3, but in that of FIG. It should be noted that in this state also, the user enjoys a certain level of security because without additional intervention on his part, the wheel can not leave its location.
    [0007] To be able to extract the wheel, the user must exert a traction force on the spindle according to the extraction direction 2. This force must be sufficient to counter the return force of the spring but less than the force F mentioned above. . The traction exerted by the user on the handle of the spindle constrains the spring 330 until the spring centering portion 342 of the distribution ring 340 comes into abutment with the portion of the groove 318 which constitutes a centering section 3181 of the spring. The pin is then in the position illustrated in Figures 5, 5a and 5b. The threaded end 314 and the end 325 of the spindle are out of the bore 101a. They are flush with the front surface of the hub shaft 220 and do not protrude therefrom. On the other hand, the portion of the spindle rod 310 which lies opposite the bore 101b is the wheel extraction portion 316 which has an outside diameter less than the maximum outer diameter D1 of the rod and also less than 15 mm. the width of the passage slot 105 formed in the bracket 100b. FIGS. 5b and 5c illustrate how it is possible to extract the wheel from the fixing lugs. The extraction portion 316 is able to pass into the slot 105. It is necessary that the user maintains during the entire operation of extraction of the wheel tensile force on the handle of the spindle. Indeed, the position shown in Figure 5, is not a stable position because the spring forces the pin to return to the position of Figure 3. Once the wheel is extracted from the brackets, the pin will resume naturally its equilibrium position inside the hub of the wheel, that is to say that which is his in Figure 3 except for the ring 320 which, it is not the position 25 of Figure 3, but in that of Figure 4. Throughout the storage phase of the wheel, the pin will remain secured to the wheel. There is, in fact, no risk that the pin is inadvertently extracted from the hub because it would have to exert a force greater than Fa. Moreover, advantageously, the spindle will keep the proper positioning to prepare the next assembly of the wheel on the cycle. To be able to put back the wheel, the user exerts and maintains a limited effort (less than Fa) on the handle of the spindle in the extraction direction 2. It thus places the spindle in the position of FIG. 5. It is then It is possible to place the wheel at its final location by aligning the internal bore 222 of the hub with the bores 101a and 101b. When it releases its traction force on the handle, the pin is placed in the position of Figure 3, the ring 320 being in the position of Figure 4. It is then sufficient to apply the tightening torque to finalize the fixation of the wheel.
    [0008] For proper operation, it is necessary that before the arrival in the state fig 5 and the state 5 itself, the ring does not slip, even under the effect of the momentum of the user. Consequently, the final force of the spring F 'must be much lower than Fa. By defining the ratio R = Fa / F', we must arrange for this ratio R to be greater than 5 2, preferably greater than at 5 and ideally between 8 and 80, for example the system gives complete satisfaction with a maximum spring force F 'of about 5 Newton and an extraction force Fa of the pin of about 50 Newton, or a maximum force of the spring F 'approximately 10 times lower than Fa (R = 5/50 = 10). FIG. 6 shows a second embodiment in which the mounting position 10 and disassembly of the wheel has a stable position of the spindle rod so that the return force of the spring 330 is retained by an indexing system. . Thus, the user does not have to exert the traction force on the handle of the spindle continuously during the entire phase of extraction (or setting up) of the wheel.
    [0009] Referring to FIG. 6a which is a partial detailed view of FIG. 6, this embodiment still includes a retractable tubular ring 320 which fits into the inner housing 222 of the shaft 220. The distribution ring 3401 has at least one slot 341 allowing it to expand radially to be inserted in the portion 319 of the rod 310. The slot 341 of the distribution ring 3401 is in this embodiment very narrow so that when the spring 330 is inserted on the centering zone 342 of the distribution ring, it induces a radial stress on this centering portion 342 to close this slot, the centering ring is thus preloaded closing by the end of the spring 330. this second embodiment, the distribution ring 3401 is longer than in the first embodiment and it is inserted radially with a sufficient radial clearance s or the split ring 320 to take another axial support 3503 at the other end of the latter, and the distribution ring 3401 is guided by two bilateral axial supports with the split ring 320. The hub / pin assembly according to the second Embodiment of the invention includes releasable retention means which maintain the spindle in a second stable equilibrium position. These releasable retention means are provided to oppose the restoring force of the spring 330 which tends to place the spindle in a configuration similar to that illustrated in FIG. 3. They consist of the cooperation of elements of the spindle with elements of the stem. These elements will be described below. The distribution ring 3401 comprises in its bore an annular protrusion 3501 projecting towards the axis 11 and having two conical portions of half-angle at the apices a and f3 connected by a radius.
    [0010] The rod 3101 comprises in its portion 3182 an annular protrusion also comprising two conical portions of the half-angle at the top oc and f3 connected by a radius. Thus, with reference to FIG. 6a, the return force F 'transmitted by the spring 330 5 to the distribution ring 3401 is countered by the bearing on the cone portions 3502 and 3102 of angle α respectively made in the distribution ring 3501 and the spindle pin 310. The radial prestressing of the spring 330 on the end of the plastic ring is sufficient to prevent it from expanding under the action of the corner cone oc. Thus the position shown in Figure 6a is a stable open position lo despite the thrust of the spring 330, thus allowing the user to assemble and disassemble the wheel without having to manually counteract the action of the return spring. We will now describe from this stable position shown in Figures 6 and 6a the passage in Figure 7 wherein the wheel is securely locked to the frame or the fork of the cycle. Figure 7 is a detailed partial view of a configuration of the spindle which apart from the distribution ring 3401 is quite similar to that illustrated in Figure 4 of the first embodiment. Starting from the configuration illustrated in FIG. 6, the user will exert an axial thrust Pa in the direction of engagement 1, thus, by isolating the pin rod 310, it will be pushed in the direction 1, of a by the return spring 330 20 as in the first embodiment but also by the push of the user in the direction 1 on the spindle handle 3701, the sum of these two actions is initially countered by the bearing reaction on the cone portions 3502 and 3102 of angle α respectively formed in the distribution ring 3501 and the spindle rod 310, the reaction of the angle cone a then tend to expand the split distribution ring and to exceed the radial prestressing threshold that the spring 330 exerts on the end of the distribution ring, this split distribution ring will then expand radially and escape the corner cone oc to engage under the action 330 dan spring s the direction 1 to a position comparable to Figure 3 of the first embodiment.
    [0011] In order to ensure good stability and ease of use, it is desirable that the force threshold Pa exerted by the user on the handle to tilt the system be between 0.5 and 3 times the effort of maximum return of the spring F 'so that the retention force of the cone portions 3502 and 3102 of angle 13, which is equal to the sum of Pa and F', is at least 1.5 (1+ 0.5) and 4 (3 + 1) times the force of the return spring F '. It should be noted that this effort will be retransmitted to the split ring 320 which will then retransmit in turn this axial force by adhesion to the inner housing 222 of the shaft 220, it is necessary for this second embodiment to size the clamping and the geometry of the split ring 320 so that the extraction force Fa is significantly greater than Pa + F '.
    [0012] By defining the ratio R '= Fa / (Pa + F'), it must be arranged for this ratio R 'to be greater than 2, preferably greater than 4 and ideally between 5 and 50, to As an example, the system gives complete satisfaction with a maximum spring force F 'of about 5 Newton, a force Pa of about 5 Newton and an axial force Fa of about 60 5 Newton, a ratio R' equal to 6 In order to properly size the tilting force threshold Pa, the radial prestressing of the spring on the distribution ring and the angle a of the cone portion must be well dimensioned in order to reach the desired threshold. The angle a must be open enough to retain the spring thrust but not too much so that the system remains reversible without arcbout, the angle α must preferably be between 50 ° to 65 °, an angle of 55 °. ° is a good compromise. From this position shown in Figure 3, then simply turn the spindle handle 3701 to screw the spindle pin and secure the wheel to the frame. This last position then corresponds to the representation detailed in FIG.
    [0013] We will now describe the operation of unlocking the wheel for disassembly. From Figure 3 and Figure 7, the user will first unscrew the spindle pin by turning the pin handle 370 in the unscrewing direction to arrive at a configuration similar to that shown in Figure 3. From from this position 20 the user will pull on the pin handle 370 by first compressing the spring 330, this first phase is then mechanically analogous to the representation of FIG. 7 until the cone portions 3103 and 3503 Angle of angle p respectively in the distribution ring 3401 and the spindle rod 310 expands the distribution ring 3501 by exceeding the radial prestressing of the spring 330 and thus rearming the system. It is then necessary to provide a clearance J (FIG. 6) so that the distribution ring 3401 can be closed and locked again when it returns to the portions of corner cones a. The angle 13 will be chosen low enough to avoid that the rearming effort is too high and that the user then comes to slide the split ring 320, an angle 13 of 5 ° to 20 ° is well. The distribution ring 3401 of this second embodiment must preferably be made of a thermoplastic having very good friction properties in order to ensure good mechanical reversibility of the cones of angles α and R.
