    Background of the invention
    The present invention relates to the field of vehicles, in particular wheeled vehicles and especially cycles, for example bicycles.
    It relates more specifically to a braking device of a vehicle, in particular a wheeled vehicle having at least one handlebar having an axis and at least one brake actuable by a brake cable having a head.
    Braking devices are known comprising: a support having a first end provided with a sleeve for fixing the handlebar, the fixing sleeve having an axis, and a second end; and a pivoting body pivotally mounted to support about a pivot axis which is substantially parallel to the axis of the attachment sleeve, the pivoting body having a brake lever extending substantially parallel to the axis of the sleeve of fixation ;
    Document EP2594469 describes such a braking device, fitted to children's bicycles, in which the pivoting body comprises a receiving cavity for the head of the brake cable and the support is provided with a guide member for the entry of the brake cable. brake cable in the support, so that the actuation of the brake lever can pull on the brake cable, which causes the braking of the vehicle. This device allows especially children with small hands to grasp the brake lever and easily apply the force required for braking.
    In contrast, the guide member of this type of braking device extends from the support, substantially perpendicular to the pivot axis, projecting towards the front of the vehicle. Also, the guide member is bulky and it is necessary to limit the dimensions.
    Moreover, this positioning of the guiding member implies that the brake cable also extends towards the front of the braking device, which is all the more cumbersome. There is especially a risk that the brake cable hinders the user when operating the brake lever.
    Object and summary of the invention
    An object of the present invention is to provide a braking device, for a vehicle comprising a handlebar and a brake cable, overcoming the drawbacks mentioned above and in particular making it possible to reduce the space requirement generated by the guide member and the cable of brake. The invention achieves its object by the fact that the pivoting body further comprises a guide member of the brake cable inlet in the pivoting body, said guide member extending along an axis transverse to a plane perpendicular to the pivoting axis, in that the second end of the support comprises a receiving cavity for the brake cable head, and in that the guide member and the brake lever extend from one side to the other. other of the support.
    The fixing sleeve makes it possible to fix the support to the handlebars of the bicycle, so that the axis of the fixing sleeve coincides with the axis of the handlebar. In this way, the support is held stationary with respect to the handlebars. Unlike the devices of the prior art, in the braking device according to the invention, the receiving cavity is formed in the support while the guide member is integral with the pivoting body. In this configuration, the brake cable enters the pivoting body at the guide member and extends into the pivoting body while the head of the brake cable is held stationary in the receiving cavity in the support. .
    Without departing from the scope of the invention, the handlebar may be provided with a handle that allows the user to manipulate the handlebars and thus steer the vehicle.
    In a nonlimiting manner, the braking device can take at least two distinct positions: a rest position in which the brake lever is not actuated, the pivoting body being arranged close to the receiving cavity, and a position actuated in which the brake lever is actuated, the pivoting body being pivoted so as to be brought towards the first end of the support, and thus towards the handle.
    In particular, the brake cable is disposed in a sheath whose one end cooperates with the guide member, for example by being housed in the guide member. Also, when the brake lever is actuated, the pivoting body pivots about the pivot axis, which has the effect of changing the position of the guide member. It follows that the guide member exerts a thrust force on the sheath, while the head of the brake cable is held in place, which leads to move the brake cable relative to the sheath, leaving the cable of said sheath, which leads to said braking of the vehicle.
    The brake lever is arranged parallel to the axis of the fixing sleeve and therefore to the handlebar axis, so that the distance between the brake lever and the handlebar is substantially the same over the entire length of the brake lever. Children with small hands can grab the full length of the brake lever.
    Furthermore, it is understood that the axis of the guide member extends laterally and not towards the front of the vehicle as can be seen in the prior art. An interest is to reduce the clutter caused by the guide member.
    The brake lever and the pivot axis are substantially parallel to the axis of the fixing sleeve, so that the brake lever and the pivot axis are substantially parallel to each other. Therefore, the brake lever is also perpendicular to said plane perpendicular to the pivot axis. The guide axis and the brake lever are both transverse to said plane perpendicular to the pivot axis.
    Also, the fact that the guide member and the brake lever extend on either side of the support means that the brake cable and the brake lever extend in opposite directions. The brake cable therefore extends on the other side of the brake lever relative to the plane perpendicular to the pivot axis so that it will not be likely to disturb the user when he actuates the brake lever. .
    Preferably, the guide member and the brake lever are disposed on either side of a plane perpendicular to the axis of the fixing sleeve and passing through the receiving cavity. The advantage is that the receiving cavity is disposed between the brake lever and the guide member and that the guide member is disposed substantially transversely relative to the receiving cavity.
    Advantageously, the support has a bent portion formed between the first end of the support and the second end of the support, and the bent portion is traversed by the pivot axis.
    It is understood that the bent portion is arranged so that the pivot axis is located above the first phalanges of the hand of the user. An interest is to improve the ergonomics of the braking device because the trajectory of the brake lever corresponds to the natural movement of the fingers during braking, and in particular the movement of the third phalanges.
    Advantageously, the support comprises an outer surface into which the receiving cavity opens. It is understood that the head of the brake cable is thus maintained in the support so that the support exerts, on the head of the brake cable, a force directed towards the outside of the support. In other words, the head of the brake cable is held in the receiving cavity and is oriented in a direction opposite to the attachment sleeve.
    Preferably, the fixing sleeve and the receiving cavity are disposed on either side of a plane containing the pivot axis and passing through the guide member.
    According to a particularly advantageous aspect of the invention, the receiving cavity is shaped so that the brake cable has, between the receiving cavity and the guide member, a curvature of an angle greater than 90 ° in the swivel body. The curvature is the projecting angle which is defined between the axis of the guide member and the direction of the brake cable at the exit of the receiving cavity. The advantage of this curvature of the brake cable is to limit the friction of the brake cable in the pivoting body and thus limit the force to be applied to the brake lever in order to brake the vehicle. It is understood that, according to this configuration, the continuity of the curvature of the brake cable is not broken by an angle too abrupt, which makes it possible to limit the friction between the brake cable and the pivoting body and to facilitate braking.
    Preferably, the receiving cavity has a bottom wall having a partially cylindrical shape having an axis, the bottom wall being configured to receive the head of the brake cable. An interest is to allow a pivoting of the brake cable head along the axis of the bottom wall of the receiving cavity. This pivoting of the head of the brake cable makes it possible to adapt to the displacement of the brake cable in the pivoting body.
    Indeed, during the actuation of the brake lever, the pivoting body pivots about the pivot axis and the brake cable is caused to slide in the pivoting body. The head of the brake cable then pivots in the receiving cavity so as to adapt to the movement of the brake cable. The bottom wall having a partially cylindrical shape, it allows the head of the brake cable to adapt to the movement of the brake cable, which limits friction and further facilitates braking.
    Particularly advantageously, the axis of the bottom wall of the receiving cavity is inclined relative to the axis of pivoting, whereby the head of the brake cable adapts more effectively to the movement of the cable in the swivel body. In particular, when the brake lever is actuated, the pivoting body pivots about the pivot axis while the head of the brake cable is held in position in the receiving cavity of the support. As a result, the brake cable is slid into the pivoting body. Thanks to the inclination of the axis of the bottom wall of the receiving cavity relative to the pivot axis, the head of the brake cable pivots in the receiving cavity so that the brake cable remains in a plane passing through the axis of the cylindrical bottom wall, that is to say by the axis of the head of the brake cable. An interest is to avoid a twist of the brake cable, which facilitates the braking operation.
    Advantageously, considered in a plane perpendicular to the pivot axis, the guide member is disposed between the pivot axis and the axis of the fixing sleeve.
    Advantageously, considered in said plane perpendicular to the pivot axis, the guide member is disposed between the pivot axis and the brake lever.
    In other words, considered in projection in the plane perpendicular to the pivot axis, the guide member is included in a triangle formed by the fixing sleeve, the pivot axis and the brake lever. An interest is to confine the guide member in a volume defined by said triangle and extending along the handlebars of the vehicle, said volume substantially defining a prism triangular base. This configuration reduces the clutter caused by the guide member and in particular to prevent it protrudes towards the front of the vehicle. In particular, this configuration makes it possible to increase the dimensions of the guide member without harming the ergonomics of the braking device.
    Preferably, the projecting angle between the guide axis and the plane perpendicular to the pivot axis is between 45 ° and 90 °.
    Considered from the plane perpendicular to the pivot axis, the guide member extends towards the axis of the fixing sleeve.
    Preferably, the guide member comprises a control wheel of the tension of the brake cable. In addition to guiding the cable in the pivoting body, the guide member thus makes it possible to adjust the tension of the brake cable. This limits the number of parts needed to perform these functions and therefore limits the overall size of the braking device.
    Still preferably, the pivoting body has an inner groove for guiding the brake cable extending between the receiving cavity and the guide member. Again, when actuating the brake lever, the pivoting body pivots about the pivot axis while the head of the brake cable is held in position in the receiving cavity of the support. As a result, the cable is slid into the pivoting body. An interest of the inner groove is therefore to guide the brake cable in the pivoting body while promoting the sliding of the cable in the pivoting body. In particular, without limitation, the inner groove may comprise a smooth side wall configured so that the brake cable slides tangentially on said wall. It is understood that the inner groove facilitates braking by limiting the friction between the brake cable and the pivoting body, while guiding the brake cable.
    Advantageously, the cross section of said inner groove is increasing from the guide member to the receiving cavity. An interest is to improve the sliding of the brake cable in the pivoting body. This configuration allows in particular the brake cable to slide in the inner groove, in a direction transverse to said groove, from bottom to top. It is understood that the cable is guided more effectively and that the friction between the brake cable and the inner groove are further reduced.
    Preferably, a return spring is mounted between the support and the pivoting body, arranged to return the braking device to a rest position when the brake lever is not actuated. An interest is that it is not necessary to exert a force on the brake lever so as to place the braking device in the rest position. In addition, the braking device can not remain locked in the actuated position, which would prevent the use of the vehicle. The invention also relates to a wheeled vehicle having at least one wheel fixed to a frame comprising a handlebar and at least one brake associated with said wheel and actuable by a brake cable having a head, said brake cable being disposed at a inside a sheath, said vehicle further comprising a braking device as described above, the brake cable passing through the guiding member and the brake cable head being disposed in the receiving cavity, a first end the sheath being housed in the guide member, while a second end of the sheath is fixed to the brake.
    Without departing from the scope of the invention, the vehicle may be a bicycle, a motorized two-wheeler or a scooter.

    Detailed description of the invention
    In Figure 1, there is shown a braking device 10 according to the invention.
    This braking device 10 is intended to be mounted on a wheeled vehicle 100, such as a cycle, which comprises a handlebar 12 provided with at least one grip handle 14, allowing the user to manipulate the handlebar 12, and to least one brake actuable by a brake cable C having a first end provided with a cable head Ca, and a second end. In known manner, the brake is intended to brake one of the wheels of the vehicle 100. In this example, the braking device 10 is fixed to a tube 16 of the handlebar 12, said tube 16 having an axis and the handle 14 being attached to said handlebar tube 12.
    The braking device further comprises a support having a first end 18a, a second end 18b, opposite the first end 18a, and a bent portion 18c. The first end 18a of the support 18 is provided with a fixing sleeve 20 for fixing the braking device to the tube 16 of the handlebar 12.
    As can be seen in FIG. 6, the fastening sleeve is split and comprises a clamping means 22. The fastening sleeve has the general shape of a cylinder which extends along an axis X. The fastening sleeve 20 is intended to grip the tube 16 of the handlebar 12 of the vehicle, so that the axis X of the attachment sleeve 20 coincides with the axis of the tube 16 of the handlebar 12 and with the longitudinal axis of the handle 14. Without out of the scope of the invention, the support 18 could be formed in one piece with the handlebar tube.
    Still in FIG. 6, it can be seen that the bent portion 18c of the support is situated between the first end 18a and the second end 18b of the support 18. In addition, the bent portion 18c forms approximately a right angle.
    Referring again to FIG. 1, it will be noted that, according to the invention, the second end 18b of the support 18 comprises a reception cavity 19 for the head Ca of the brake cable C. Said reception cavity 19 will be described in more detail later.
    According to the invention, the braking device 10 further comprises a pivoting body 24, illustrated in FIG. 2, which is pivotally mounted relative to the support around a pivot axis Y. The pivot axis Y is substantially parallel to the axis X of the fixing sleeve 20 and therefore to the longitudinal axis of the handle. This pivot axis Y is disposed in the bent portion 18c, between the first end 18a and the second end 18b of the support 18. In addition, the pivot axis Y passes through the bent portion 18c of the support 18.
    The pivoting body 24 comprises a brake lever 26 extending substantially parallel to the axis X of the attachment sleeve 20, from a first end 24a of the pivoting body 24. In other words, the brake lever 26 extends perpendicular to the body pivoting 24 from the first end 24a of the pivoting body.
    In particular, the brake lever 26 extends substantially parallel to the handle 14, along substantially the entire length of the latter.
    In view of the above, it is understood that the pivot axis Y, the axis X of the fixing sleeve 20, the longitudinal axis of the handle 14 and the brake lever 26 are substantially parallel.
    The first end 24a of the pivoting body 24 is disposed opposite a second end 24b of the pivoting body, which is mounted in pivot connection with the support 18, about the pivot axis Y. For this purpose, the second end of the pivoting body comprises a pair of wings 28, 30 which are disposed on either side of the width of the bent portion 18c of the support 18.
    The two wings 28, 30 surround a portion of the support which extends between the bent portion 18c and the second end 18b of the support. The ends of the two wings 28, 30 each have a hole receiving a shaft 32 which passes through the bent portion 18c of the support 18 to provide the pivot connection between the pivoting body 24 and the support 18.
    As can be seen in Figure 2, the pivoting body 24 further comprises a guide member 34 of the brake cable C in the pivoting body. The guide member 34 has a substantially cylindrical shape and extends along a guide axis Z, from a portion of the pivoting body located between the first end 24a of the pivoting body 24 and the second end 24b of the pivoting body 24. More precisely , considered in the plane P perpendicular to the pivot axis, the guide member 34 is disposed between the pivot axis Y and the brake lever 26.
    Furthermore, considered in the plane P perpendicular to the pivot axis Y and in projection on an axis passing through the pivot axis Y and the axis X of the fixing sleeve 20, the guide member 34 is arranged between the pivot axis Y and the axis X of the fixing sleeve 20.
    According to the invention, the guide axis Z of the guide member 34 extends transversely with respect to a plane perpendicular to the pivot axis Y. In particular, the brake lever 26 and the guide member 34 extend on either side of the support 18, in opposite directions.
    In other words, the guide member 34 is included in a volume delimited by the fixing sleeve 20, the pivot axis Y and the second end 18b of the support 18 and extending along the tube 16 of the handlebar 12, said volume substantially defining a triangular prism. An interest is to reduce the clutter caused by the guide member 34 and in particular to prevent it protrudes towards the front of the vehicle. In particular, this configuration makes it possible to increase the dimensions of the guiding member 34 without harming the ergonomics of the braking device 10.
    In this example, the projecting angle between the guide axis and the plane P perpendicular to the pivot axis is of the order of 60 °.
    In this nonlimiting example, the guide member comprises a control wheel of the tension of the brake cable C.
    Furthermore, the pivoting body 24 has an internal groove 36, comprising a groove inlet 36a, a throat outlet 36b, a side wall 38, preferably smooth, the inner groove 36 for guiding the brake cable in the pivoting body . The inner groove 36 extends from the guide member 34, at the groove inlet 36a and opens into the receiving cavity 19 of the support 18, at the throat outlet 36b. In particular, the inner groove 36 describes a curvature defined between the groove inlet 36a and the throat outlet 36b of the order of 125 ° according to a first embodiment, and a curvature of the order of 120 ° according to a second embodiment. The cross section of the inner groove 36 is increasing from the guide member 34 to the receiving cavity 19 and thus from the groove inlet 36a to the throat outlet 36b. Preferably, the cross section of the inner groove 36, at the groove outlet 36b, is twice as large, preferably three times larger than the cross section of the inner groove at the groove inlet. 36a.
    In FIG. 3, it can be seen that the reception cavity 19 of the head C of the brake cable C opens into an outer surface 40 of the support 18 and is thus oriented towards a direction opposite to the attachment sleeve 20. The cavity 19 is disposed between the bent portion 18c of the support and the second end 18b of the support.
    According to the first embodiment, the distance between the pivot axis Y and the receiving cavity 19 is substantially equal to 22mm and the distance between the pivot axis and the guide member 34 is substantially equal to 18mm. According to the second embodiment, the distance between the pivot axis Y and the receiving cavity 19 is substantially equal to 32mm and the distance between the pivot axis and the guide member 34 is substantially equal to 27mm.
    The receiving cavity further comprises a bottom wall 42 having a partially cylindrical shape, preferably having the shape of a half-cylinder. The bottom wall 42 constitutes a bearing surface for the head C of the brake cable C, oriented towards a direction opposite to the fixing sleeve 20. The bottom wall 42 has an axis A defined as the axis of the partially formed cylinder . Particularly advantageously, the receiving cavity is configured so that the axis A of the bottom wall 42 of the receiving cavity 19 is inclined with respect to the pivot axis Y, preferably at an angle has comprised between 35 ° and 55 °, still preferably an angle substantially equal to 45 °. The support 18 also comprises a slot 44 passing through the support and opening into the receiving cavity. In the example of FIGS. 4 and 5, it can be seen that the head Ca of the brake cable C has the shape of a cylinder having an axis A ', cooperating with the bottom wall 42 of the receiving cavity 19. receiving cavity is configured so that the bottom wall 42 keeps the head Ca of the brake cable C resting in the support 18, in a direction opposite to the fixing sleeve 20. The axis A of the wall of bottom 42 of the receiving cavity 19 being inclined relative to the pivot axis, it is understood that the axis A 'of the head Ca of the brake cable C is substantially coincident with the axis A of the bottom wall 42, so that the axis A 'of the brake cable head is also inclined with respect to the pivot axis Y.
    Therefore, this configuration allows the pivoting of the brake cable head in the reception cavity 19 about the axis A of the bottom wall 42, allowing a rotation of the brake cable C, along the axis A of the bottom wall, during the actuation of the brake lever 26, said brake cable being guided in rotation in the slot 44 of the support 18.
    The brake cable C passes through the slot 44 and extends substantially towards the fixing sleeve 20, transversely to the axis X of the fixing sleeve 20.
    The brake cable also passes through the pivoting body 24. More precisely, the brake cable C extends in the pivoting body within the internal groove 36, tangentially resting on the side wall 38 of the internal groove 36, as well as 'through the guide member 34, which guides the brake cable C. The brake cable C enters the pivoting body 24 at a first end 34a of the guide member 34 and leaves it at level of throat outlet 36b.
    As illustrated in FIG. 8, the brake cable C has, in the pivoting body 24, a curvature of an angle greater than 90 ° between the reception cavity 19 and the guide member 34, preferably an angle between 90 ° and 130 °, which makes it possible to limit the friction of the brake cable C in the pivoting body 24.
    Furthermore, the guide member 34 and the brake lever 26 extend on either side of the support 18, so that the brake cable C and the handle 14 extend in opposite directions. It is understood that there is no risk that the user is bothered by the brake cable C when he wants to operate the brake lever.
    In addition, the brake cable C, outside the braking device 10, extends in known manner in a sheath G. The first end of said sheath G is housed in the guiding member 34, while the second end of the sheath G is attached to the body of a brake caliper. The second end of the brake cable C is also connected, in known manner, to a movable part of the brake caliper, movable relative to the body of the brake caliper.
    Figures 4 and 6 illustrate a braking device 10 according to the invention, in the rest position, in which the brake lever 26 is not actuated. The pivoting body 24 has a housing 46 intended to cooperate with the support 18, by receiving a portion of the support which extends between the bent portion 18c and the second end 18b of the support 18.
    In this rest position of the braking device 10, the brake cable C extends in the groove 36 of the pivoting body 24, bearing tangentially on the lateral wall 38, near a lower wall 48 of the groove 36.
    When the brake lever is actuated, that is to say when the braking device 10 is moved from the rest position shown in FIGS. 4 and 6 to an actuated position represented in FIGS. 7, the pivoting body 24 pivots about the pivot axis Y, which causes the guide member 34 to move in rotation about the pivot axis Y. As a result, the guide member approaching the fixing sleeve 20 and pushes on the sheath G, while the head Ca of the brake cable C is held in the receiving cavity 19. The actuation of the brake lever 26 therefore has the effect of pushing the sheath G so that the brake cable C moves relative to the sheath G. It follows that the second end of the brake cable moves towards the second end of the sheath, then operating a traction on the moving part brake caliper.
    Preferably, the angular travel of the pivoting body 24 about the pivot axis Y, between the rest position of the braking device 10 and the actuated position of the braking device 10, is less than 90 °, more preferably less than 45 °.
    During the actuation of the brake lever 26, the brake cable C slides in the inner groove 36 of the pivoting body 24 and approaches an upper wall 50 of the inner groove 36. At the same time, the head Ca of the cable brake C pivots about the axis A of the bottom wall 42 of the receiving cavity 19, so that the brake cable is guided in the slot 44. Guiding the brake cable C in this way, last slides in the inner groove 36 of the pivoting body 24, from bottom to top and tangentially to the side wall 38 of the inner groove 36, during all the actuation of the brake lever 26.
    In other words, thanks to the inclination of the axis A of the bottom wall 42 of the receiving cavity 19, and therefore thanks to the inclination of the head Ca of the brake cable C with respect to the axis of pivoting Y, the brake cable retains a tangential bearing with the side wall 38 of the inner groove 36, regardless of the position of the brake lever 26. The brake cable slides tangentially along the side wall 38 of the This configuration improves the guiding of the brake cable C in the pivoting body 24 and makes it possible to avoid a twisting of the brake cable, which limits the friction and facilitates the braking of the vehicle.
    Figures 5 and 7 illustrate the braking device according to the invention in the actuated position, that is to say for which the brake lever 26 has been actuated. The guide member 34 is positioned close to the fixing sleeve 20. It can be seen that the brake cable C is always tangentially resting on the side wall 38 of the internal groove 36, close to the upper wall 50 of the groove. inside 36.
    Furthermore, to allow the passage from the actuated position to the rest position, the braking device 10 comprises a return spring 52 which is mounted between the support 18 and the pivoting body 24.
    Figure 8 is a sectional view, from below, showing the path of the brake cable C from the guide member 34, in the inner groove 36 and through the slot 44 of the support 18. It is found that the brake cable describes a circular arc with a gentle curvature so that braking is improved.
    FIG. 9 illustrates a wheeled vehicle 100 comprising a braking device 10 according to the invention. In this non-limiting example, the vehicle 100 is a bicycle. Without departing from the scope of the invention, the vehicle 100 could be a motorized two-wheeler or a scooter.
    The braking device 10 is mounted on the tube 16 of the handlebar 12 of the vehicle 100. The latter comprises at least one wheel 110 fixed to a frame 120 and a brake 130 which is associated with said wheel for braking and which is connected to the device 10 by the brake cable C, moving relative to the sheath G. In particular, the first end of the sheath is housed in the guide member 34, while the second end of the sheath is attached to the body of the brake caliper 130. The second end of the brake cable is also connected to the brake caliper 130.
