    [0001] The present invention relates to a device for guiding a flexible connecting member passing inside a cycle frame to provide a device for guiding a flexible connecting member passing inside a cycle frame. connect a control member carried by a cycle hanger to a receiver. The brakes and the cycle derailleurs are generally controlled by the cyclist using control members carried by the cycle hanger. For the actuation respectively of the brakes or derailleurs, the control members are connected thereto by a flexible connecting member which conventionally comprises a cable attached to the frame of the cycle. These are fully mechanical control means.
    [0002] To date there are also electromechanical battery control means, in particular for controlling a cycle derailleur, and in this case, the control members are connected to an electrical receiver via connecting means under form of electric wires.
    [0003] There are also hydraulic control means, in particular for the control of a hydraulic brake, and in this case, the control members are connected to a hydraulic receiver by means of connecting means in the form of pipes of the type Durit ©, usually made of rubber reinforced with textile or metallic plies.
    [0004] All these control means thus require the use of connecting members in the form of cables, electrical wires or pipes. Instead of attaching these link members in a conventional manner to the outer faces of the cycle frame, today's cycle manufacturers often choose to route these connecting members, as far as possible, within the different tubes of which the cycle frame is composed. This produces a final product that is more aerodynamic, more aesthetic and in which the connecting members are well protected. However, there is still a critical zone which is the front of the cycle because virtually all the connecting members from the control members carried by the hanger enter the front part of the frame to pass through some of the tubular elements thereof. . In this regard, the connecting member that connects the control member of the front brake to it passes in the case of a brake integrated in the fork advantageously inside the cycle bracket and then in the pivot fork to reach the brake. The other connecting members from the hanger enter further into the frame through a respective, often lateral opening, provided near the front end of either the horizontal tube of the frame or the diagonal tube of the frame, depending on the location. of the organ to be controlled. In general, a steering sleeve forming part of the cycle frame, and the fork pivot tube installed therein, leave little room for the passage of the connecting members. In this regard, it should be noted that the electrical son are easily integrable because they are very flexible and small diameter. This is unlike cables and pipes that can not have very small radii of curvature. The concept of a steering socket must be understood in its broad sense as being a tubular element able to receive a headset and to be traversed by a fork pivot. DE 20 2013 005 555 U1 discloses a device for guiding a flexible connecting member passing through a tube of a cycle frame, in particular a direction sleeve. This device comprises an insert in the form of a plate integrated on one side of the steering sleeve. This insert is received in a cutout substantially at half height of the direction sleeve. The insert is fixed in the cutout with a screw and has several channels for the passage of functional elements such as Bowden cables. The channels open out onto inlet openings of the functional elements. A disadvantage of this device is that it requires a direction sleeve having a relatively large width to provide a space large enough for the integration of this device which is bulky in width. For the same reason, this device can not be disposed up close to an upper bearing of the headset disposed in the steering sleeve, while it would be preferable to be able to bring the connecting members into the frame. as high as possible to reduce the length of the connecting members to the outside of the cycle frame to a minimum, between the control members and the entrance openings in the frame. The object of the invention is to provide a device for guiding a flexible connecting member passing inside a cycle frame which is able to overcome the disadvantages of known devices. The guiding device 5 according to the invention makes it possible to hide in the frame a maximum length of the connecting members for better aerodynamics and better integration, and to refine the portion of the steering sleeve which is located between the upper bearing and the lower bearing of the headset to thus reduce the frontal surface of the cycle. In other words, thanks to the guiding device according to the invention, the inner walls of the steering sleeve can in a central zone thereof be very close to the fork pivot tube. The object of the invention is a device for guiding a flexible connecting member passing inside a cycle frame for connecting a control member carried by a cycle hanger to a receiver, said link entering the cycle frame by an inlet opening provided on a steering sleeve, the guide means forming an insert being integrable with the steering sleeve and having at least one guide channel of said connecting member for communicating. with said inlet opening, characterized in that said insert is adapted to be disposed inside the steering sleeve in a common housing with a said upper bearing of a headset, said insert having a so-called face interior adapted to at least partially bypass a fork pivot inserted in the steering sleeve, and an outer face containing said guide channel. According to other features of the invention: - said insert has a generally arcuate shape. said insert forms a closed circle; said insert is on its periphery provided with locking means in rotation with respect to the steering sleeve; said rotational locking means comprise at least one non-circular conformation cooperating with a surface of complementary shape provided in said common housing; said insert is in two parts forming together said closed circle; - The two parts of the insert are extended downwards and have at the lower part of their inner face a recess forming a receiving bowl of said upper bearing; said insert is in a single annular piece forming said closed circle; said insert is disposed above said upper bearing, outside a tapped cowl cooperating with a thread provided at the upper part of a fork pivot inserted in the steering sleeve; said insert is disposed below said upper bearing; said inlet opening is arranged in a protuberance directed forwards at the upper end of the steering sleeve; and a plurality of parallel guide channels relative to each other are provided on said outer face of the insert, and a corresponding number of inlet openings are provided at the upper part of the direction sleeve, at the level of a respective guide channel when said insert is in said common housing. Other characteristics and advantages of the invention will emerge from the following description of a non-limiting embodiment of the invention, with reference to the appended figures in which: FIG. 1 is a schematic perspective view showing the upper front part of a cycle, the steering sleeve of which is provided with a guiding device according to the invention; FIG. 2 is an exploded perspective view showing the upper portion of a steering sleeve and an upper bearing associated with a guide device according to the invention; - Figure 3 is an exploded perspective view showing the guide members of a two-part guide device according to the invention; Figure 4 is a perspective view showing a variant of a guide member; - Figure 5 is a schematic side sectional view of a steering sleeve provided with the guide device according to the invention; - Figure 6 is a schematic sectional front view illustrating the guiding device of Figures 2, 3 and 5 wherein the lower portion of the guide member forms a bowl receiving an upper bearing of a headset; FIG. 7 is a diagrammatic sectional front view illustrating a variant of the guiding device according to the invention disposed below an upper bearing of a headset; - Figure 8 is a schematic front sectional view illustrating the guide member according to the invention disposed immediately above an upper bearing of a headset; and FIG. 9 is a partial perspective view from above showing the common housing of the upper bearing and the guiding device according to the invention. In the figures, identical or equivalent elements will bear the same reference signs. FIG. 2 shows in an exploded view the upper part of a steering sleeve 1 and an upper bearing 2 associated with a guiding device 3 according to the invention. The upper bearing 2 is part of a headset and must be placed in a housing 4 provided at the upper end of the steering sleeve 1. A lower bearing 5 (shown schematically in FIG. 5) is received in a similar housing at the lower end of the steering sleeve 1. For more details about the headset, reference is made to the application FR 2 954 266 of the applicant. A fork pivot tube 6 passes through the direction sleeve 1 projecting upwards to be connected to the rear end of a bracket 7 which at its front end carries a hanger 8. The fork pivot tube 6 is at its upper part provided with a threaded flange 9 which can be in the form of a sleeve fixed on the fork pivot tube. The threaded flange is intended to cooperate with a threaded cap 10 provided with a flange 11 so as to obtain an axial clamping by plating the bearings 2 and 5 against their respective housing 4. A compression ring 10 'of conical shape is inserted between the upper bearing 2 and the flange 11 of the threaded cap 10 to cooperate with a correspondingly shaped surface of the bearing 2.
    [0005] The hanger 8 carries control members 12, 13 allowing the rider to control the front and rear brakes (not shown), and advantageously also the derailleur (not shown). The control members 12, 13 are connected to the devices to be controlled by means of flexible connecting members 14 in the form of cables, electrical wires or pipes depending on the control mode, as explained above. above. One of these designated connecting members 14 '(see FIG. 5) leaves the hanger to enter, in a manner known per se, directly into the bracket 7 and then to pass through the fork pivot tube 6 for the control of the front brake. The other flexible connecting members 14 enter the cycle frame through a respective opening 15 provided on the front face of the steering sleeve 1. The guiding device 3 according to the invention serves to guide one or more flexible connecting members. 14 inside the direction sleeve 1 to then go through the horizontal tube 16 or the down tube (not shown) thereof. The guiding device 3 forms an insert integrated in the direction socket 1 and comprising at least one guide channel 17 (see FIG. 3) able to receive a flexible connecting member 14 and communicating with the inlet opening 15. According to the invention, the insert 3 is adapted to be disposed inside the direction sleeve 1 in the housing 4 which is a common housing to the insert and the upper bearing 2 of the headset. The insert 3 has a shape in an arc whose inner face 18 is able to at least partially surround a fork pivot 6 inserted in the direction sleeve 1, and an outer face 19 preferably has a groove However, this guide channel can also be closed towards the outside 30 by a thin skin, for example of a thickness of about 1 mm. In the example illustrated in Figures 2 to 3 and 5 to 8, the insert 3 forms a closed circle, in the form of a ring or cylinder. The insert 3 is on its periphery provided with locking means in rotation relative to the direction sleeve 1. These rotation locking means preferably comprise at least one non-circular conformation such as a flat part cooperating with a surface of complementary form 21 provided in the housing 4. In one embodiment, the insert 3 is in one annular piece forming a closed circle. It can be arranged above the bearing 2 by extending around the threaded cap 10 and the compression ring 10 ', as illustrated in FIG. 8. It can also be arranged below the bearing 2, as this is illustrated in FIG. 7. FIGS. 2, 3, 5 and 6 show an advantageous embodiment in which the insert 3 is in two parts, namely a first part 3A and a second part 3B (see in particular FIG. 3). The first and second parts 3A, 3B are generally semicircular and are in their junction plane provided with pins 22 respectively receiving holes 23 receiving the pins 22 when the two parts are joined.
    [0006] According to a characteristic of the invention, the two parts 3A, 3B of the insert 3 are extended downwards and have at the lower part of their inner face a recess (see FIGS. 2, 5 and 6) forming a receiving bowl According to a feature of the invention, an inlet opening 15 is provided in a protrusion 25 directed forwards at the upper end of the steering sleeve 1, at the guide channel 17. when the guiding device 3 is in the housing 4. FIG. 4 shows a guiding device 3 'according to the invention formed by a generally semi-circular element forming an insert comprising a single guiding channel 17. This insert can be arranged on one side in the housing 4 or be doubled to form a closed circle with two opposite guide channels. Of course, this insert can also be annular with two opposite channels. Figures 2, 3, 5 to 6 and 8 show an advantageous embodiment of the insert 3 having several parallel guide channels 17, and a corresponding number of inlet openings 15 provided in the upper part of the sleeve direction 1 and arranged to communicate with a respective channel of the insert 3 when it is put in place in the direction socket. In the housing 4, outlet openings 15 'for the flexible connecting members 14 are provided substantially opposite the inlet openings 15.
    [0007] Each flexible connecting member 14 is advantageously provided with a sleeve 26 which must be inserted into the inlet opening 15 to form a stop and to seal the opening. Thus is obtained a guide device easily integrable in a direction sleeve at the upper bearing of a headset disposed in the direction sleeve. Thanks to the invention, the flexible connecting member inlet openings extending from a control member carried by a cycle hanger can be placed immediately below the cycle bracket and the length of the connecting members outside the cycle frame is substantially reduced.
    [0008] Another advantage of the invention is that the width of the portion of the steering sleeve extending between the upper bearing and the lower bearing can be substantially reduced, which gives aerodynamic and aesthetic advantages. Of course, the invention is not limited to the examples illustrated and described, but a large number of variants and combinations can be envisaged without departing from the scope of the invention.
