BACK-UP FOR BIKES ON VEHICLE HITCH The invention relates to the field of vehicles, in particular motor vehicles. More specifically, it relates to the support of one or more bikes by a bicycle carrier secured to a vehicle.

Today, the use of a bicycle is very varied, it is common for a bicycle user to go outside the cities to practice off-road cycling or mountain biking, city streets and other roads. for vehicles that are already congested with motor vehicles, and the terrain of cities that does not correspond to the use of an off-road bicycle or an ATV.

Thus, a user wishing to go with his bike outside the cities will have to accommodate a means of transport for his bike, a bike being too bulky to easily be placed in the trunk of a city type motor vehicle . Even if a dismountable or foldable bicycle in any way could be arranged in the trunk of a motor vehicle, this motor vehicle could not transport several bicycles.

In addition, it is also common to take one or more bikes (city bikes, off-road or mountain bikes) when leaving on a trip. Whether they are city, off-road or mountain bikes, the need is the same: to be able to transport one or more bikes using a vehicle. It is known to use a bicycle carrier secured to a motor vehicle, to meet the need cited above.

There are a multitude of types of bicycle carriers, which can be divided into three categories:

- bicycle carriers on the roof,

- bicycle carriers on tailgate,

- bicycle carriers on a coupling device.

Roof rack bikes consist of two separate parts: roof racks, which attach to the roof of a vehicle, and the bike rack, which attaches to these roof racks. This type of bicycle carrier has the advantage of providing good fixing of bicycles, it guarantees good security as to the maintenance of position of the bikes on the roof of a vehicle.

However, roof bike carriers have the drawback of not being ergonomic in that it is difficult to place the bikes on the roof of a vehicle, particularly if this vehicle has a large roof height. In addition, a vehicle equipped with such a bike rack and supporting one or more bikes cannot access all spaces with limited access by a defined vehicle height. In addition, the bicycle or bikes arranged on the roof affect the aerodynamics of the vehicle, increasing fuel consumption.

Bike carriers on tailgate consist of a frame, integral with a tailgate by means of straps, the frame comprising a fork, to receive one or more bikes. This type of bicycle carrier has the advantage of being quickly mountable on the tailgate of a vehicle.

However, bike carriers on the tailgate have the disadvantage of not being able to adapt to any type of vehicle. Indeed, this type of bike carrier can not be mounted on a tailgate comprising a composite material or a flap being composed only of a window. In addition, the fixing system of this type of bicycle carrier is not completely reliable in that it can only support a limited quantity of bicycles without causing the possible separation of the bicycle carrier from the tailgate, because of the weight of the bikes.

Bicycle carriers on coupling means consist of a coupling, a coupling ball for example, and a frame supporting several bikes. This type of bicycle rack has the advantage of being robust and ergonomic. Bikes are easily set up and held in position with this type of bike rack.

However, bicycle carriers on the coupling means have the drawback of obscuring the rear visibility of the driver, the rear lights of the vehicle and the license plate. In addition, they prevent the opening of the trunk of the vehicle.

Document EP2134571 describes a bicycle support intended to be positioned on the coupling of a vehicle, this bicycle support being able to extend, by a guided longitudinal translation through the bumper of the vehicle, and more particularly under the bumper, at the level of the underbody of the vehicle. The bicycle rack includes a means for tilting the bikes, allowing access to the trunk of the vehicle.

However, this bicycle support has the disadvantage of masking the rear visibility of the driver, when bicycles are arranged on the bicycle support. The device also masks the rear lights of the vehicle and its license plate. .

A first objective is to provide a compact and ergonomic bicycle support.

A second objective is to provide a bicycle rack that does not obscure the driver's rear visibility, nor the lights or the license plate of a vehicle.

A third objective is to provide a bicycle support ensuring effective maintenance of bikes.

To this end, it is proposed, firstly, a bicycle support intended to be mounted on a vehicle, this bicycle support comprising:

- two slide supports, intended to be mounted on a vehicle hitch type fitting;

- Two slides, intended to be mounted sliding along a first axis, respectively, in the two slide supports, these two slides being sliding between an initial position and a deployed position;

o a first position, in which the frame support extends along a second axis, the first axis and the second axis being included in a first plane; and o a second position, in which the frame support extends along a third axis, the first axis and the third axis being included in a second plane, distinct from the first plane.

Advantageously, such a support allows to easily hang one or more bikes on a motor vehicle.

This support, when not in use and the slides are in the initial position, is compact, so that it can be stored completely under the motor vehicle, at its base.

Various additional characteristics can be provided, alone or in combination:

the bicycle support comprises two wheel supports, linked to the slides;

the bicycle support comprises a base, intended to be fixed to the vehicle coupling hitch, the two slide supports being mounted in rotation with the base;

the bicycle support comprises a means of locking in translation, making it possible to prevent the sliding of the two slides in the two slide supports, this means of locking in translation comprising:

the bicycle support comprises a means of locking in translation, making it possible to prevent the sliding of the two slides in the two slide supports, this means of locking in translation comprising:

o two translation locking keys, sliding in a secondary bore dug both in the base and partly in the slide supports, the translation locking keys having racks extending at their ends, o a main wheel , comprising a toothed portion capable of meshing with the racks;

the bicycle support comprises a rotation locking means, making it possible to prevent the pivoting of the slide supports, this rotation locking means comprising:

o two rotation locking keys, sliding in two primary bores, hollowed out partly in the base and partly in the slide supports, the rotation locking keys each comprising a primary return spring, pressing on a primary flange, so as to keep the rotation locking key in contact with the slide, o a handle, connected to each rotation locking key by means of a sheath and cable system, so as to be able to spread the keys locking the slides in rotation, by pulling on the handle;

FIG. 1 shows a vehicle 1 (in dotted lines), comprising a support 2 for bicycles (in solid bold lines) disposed near a base 3 of vehicle 1, the support 2 for bicycles being more particularly secured to the vehicle coupling 1.

The vehicle 1 may for example be a particular motor vehicle or utility vehicle.

An orthogonal coordinate system XYZ is defined with respect to vehicle 1 comprising three perpendicular axes two by two, namely:

an X axis, defining a longitudinal, horizontal direction, merged with the general direction of movement of the vehicle, a Y axis, defining a transverse, horizontal direction, which with the X axis defines a horizontal XY plane, a Z axis, defining a vertical direction, perpendicular to the horizontal XY plane.

In the following description, and with reference to the reference defined above, the terms "longitudinal" or "longitudinally" refer to a direction coincident with the X axis, the terms "transverse" or "transversely" refer to a direction coincident with the Y axis, and the terms "vertical" or "vertically" refer to a direction coincident with the Z axis.

As illustrated in Figure 2, the bicycle support 2 comprises a base 4 secured to the coupling fitting.

On this base 4 are rotatably mounted two supports 5 of slides, by means of an axis 6, the supports 5 of slides pivoting about an axis parallel to the axis Y.

The supports 5 of the slides are profiles having in section a shape of a parallelepiped, these profiles extend in an L-shape forming a support surface 7.

The base 4 comprises a means 8 for blocking the rotation of the supports 5 of the slides (see box, in FIG. 4).

The means 8 for locking in rotation comprises two keys 9 for locking in rotation, sliding in two primary bores 10, hollowed out both partly in the base 4 and partly in the supports 5 of slides. The primary bores 10 extend along an axis parallel to the Y axis.

The means 8 for locking in rotation comprises a handle 11 connected to each key 9 for locking in rotation, by means of a system 12 of sheaths and cables (visible in FIG. 4).

The bicycle support 2 comprises two slides 13 having in section a shape of a parallelepiped, the two slides 13 each comprising, at a first end 14, a primary stop plate 15, and comprising, at a second end 16, a flange

17.

The slides 13 slide in the supports 5 of slides between two positions:

an initial position, in which the slide supports 5 are in abutment on the flanges 17 of the slides, so as to block the translation of the slides 13 along a first longitudinal axis, and a deployed position, in which the slides 13 have slid up that the primary abutment plates 15 are brought into contact with the bearing surfaces 7 of the slide supports 5, so as to block the translation of the slides 13 along the first axis, in the longitudinal direction.

The base 4 comprises a means 18 for locking in translation of the slides 13 (see box in Figure 4).

The means 18 for translational locking comprises two keys 19 for translational locking, sliding in a secondary bore 20, hollowed out both in the base 4 and partly in the supports 5 of slides, the secondary bore 20 extending along an axis parallel to the Y axis.

The means 18 for translational locking comprises a main wheel 21, screwing into a bore 22 in the base 4. The hole 22 extends along a longitudinal axis and opens into the secondary bore 20.

The bicycle support 2 comprises two wheel supports 23, mounted in rotation relative to the slides 13, at the second end 16 of the slides 13, the wheel supports 23 pivoting about an axis parallel to the Z axis.

The wheel supports 23 pivot between two positions:

an initial position, in which the wheel supports 23 extend along a transverse axis, and a deployed position, in which the wheel supports 23 extend along a longitudinal axis.

The wheel supports 23 each comprise two hooks 24, capable of receiving a wheel of a bicycle.

The wheel supports 23 are used to position the wheel of a bicycle, so as to keep it in an upright position.

The rotation of the wheel supports 23 can be blocked by means of two secondary knobs 25, which are screwed both into the wheel supports 23 and the slides 13.

The bicycle support 2 comprises two frame supports 26, mounted in rotation relative to the slides 13, at the second end 16 of the slides 13, each frame support 26 pivoting about a longitudinal axis.

Each frame support 26 is mounted for rotation relative to one of the two slides 13.

The frame supports 26 pivot between two positions:

an initial position, in which the frame supports 26 extend along a transverse axis, a deployed position, in which the frame supports 26 extend along a vertical axis.

The rotation of the frame supports 26 can be blocked by means of two tertiary knobs 27, which are screwed into both the frame supports 26 and the slides 13.

As illustrated in Figure 3, the bicycle support 2 is arranged, according to a first configuration, in which the bicycle support 2 is arranged under the vehicle 1, at its base 3. The support 2 of bikes thus arranged is not visible and does not clutter the rear of the vehicle 1, the trunk of the vehicle is then accessible.

In this configuration, the slides 13, the wheel supports 23 and the frame supports 26 are respectively arranged in their initial position.

As illustrated in Figure 4, the bicycle support 2 is arranged in its first configuration, described above.

In this configuration, the main wheel 21 is screwed into its bore 22. The main wheel 21 has a beveled shape at its end, so as to come to bear and push the keys 19 for locking in translation in the bore 20 secondary, the keys 19 for locking in translation also having a beveled shape at their end.

Thus, the keys 19 for locking in translation are in support of the slides 13 and prevent their translation by adhesion.

In this configuration, the keys 9 for locking in rotation are held at the bottom of the primary bores 10, by means of primary return springs 28 wound around the keys 9 for locking in rotation and in support of primary primary collars 29 extending from the rotation locking pins 9. Thus, the keys 9 for locking in rotation prevent the rotation of the slide supports 5. In this configuration, the primary return springs 28 are relaxed.

As illustrated in Figure 5, the bicycle support 2 is arranged in a second configuration, in which the slides 13 have slid to their deployed position, as indicated by the black arrows.

In this configuration, the main dial 21 has been partially or completely unscrewed, as illustrated in Figure 6 by a white arrow.

When the main dial 21 has been unscrewed, the keys 19 for translational locking have slid in the secondary bore 20. Indeed, two secondary return springs 30, wound around the keys 19 in translational blocking, bearing on secondary flanges 31 extending from the keys 19 in translational blocking (as shown by the black arrows of the Figure 6) have pushed the keys 19 of translational locking.

The secondary return springs 30 have gone from a compressed state to a relaxed state.

The keys 19 for translational locking no longer being in contact with the slides 13, the slides 13 were then able to slide to their deployed position.

As illustrated in Figure 7, the bicycle support 2 is arranged in a third configuration, in which the frame supports 26 have pivoted to their deployed position, as indicated by the black arrows.

To pass the frame supports 26 in their deployed position, it was necessary to unscrew the knobs 27 tertiary, to release the rotation of the frame supports 26.

The frame supports 26 each include an extension 32 sliding inside the frame supports 26.

The extensions 32 are held in position by means of screws 33. In other words, the supports 26 of the frame are telescopic. These extensions make it possible to adjust the support 2 of bikes to the height of the bikes, so as to support the frame of the bikes, the extensions 32 comprising a support means 34 for the frame of the bikes.

As illustrated in Figure 8, the bicycle support 2 is arranged in a fourth configuration, in which the wheel supports 23 have pivoted to their deployed position, as indicated by the black arrows.

The wheel supports 23 can only pivot if the frame supports 26 have previously pivoted into their deployed position.

To pass the wheel supports 23 in their deployed position, it was necessary to unscrew the secondary knobs 25, to release the rotation of the wheel supports 23.

As illustrated in Figure 9, the bicycle support 2 is arranged in a fifth configuration, in which the slide supports 5 have pivoted by an angle A, as shown by the black arrow. To rotate the supports 5 of slides, it is necessary to disarm the means 8 for locking in rotation, it is necessary to pull on the handle 11 (as shown by a black arrow in FIG. 10), in order to slide the keys 9 from locking in rotation in the primary bores 10, so that the keys 9 for locking in rotation are located only in the base portion 4 of the primary bores 10 (as shown by a black arrow in FIG. 10).

In this configuration, the primary return springs 28 are compressed, as can be seen in FIG. 10.

The pivoting of the supports 5 of slides advantageously makes it possible to tilt two bikes (shown in bold line), arranged vertically on the support 2 of bikes, the rear wheels of the two bikes being arranged on the hooks 24 and the frame of the two bikes resting on the support means 34, so that the trunk of the vehicle 1 can be opened, without having to remove the bikes from the bicycle support 2 or without having to dismantle the bicycle support 2 itself.

According to a first embodiment, illustrated in FIGS. 11 and 12, the main wheel 21 comprises a toothed portion 35, able to mesh with racks 36 extending at the end of the keys 19 for locking in translation.

When the main wheel 21 is screwed into its bore 22, its toothed portion 35 meshes with the racks 36 and the keys 19 for locking in translation slide in the secondary bore 20, the secondary bore 20 being split into two bores 20 secondary, vertically offset from each other, as illustrated in Figure 12. According to a second embodiment, illustrated in Figure 13, the bicycle support 2 does not include a base 4, the support 2 for bicycles being secured to the coupling hitch of the vehicle 1 by means of the slide supports 5.

The bicycle support 2 comprises the slides 13 previously described, which each include the primary stop plate 15, and a secondary stop plate 37.

Each slide 13 slides in its slide support 5 between two positions:

an initial position, in which the secondary abutment plate 37 bears on a first face 38 of the slide support 5, so as to block the translation of the slides 13 along the first axis, in the direction of advance of the vehicle, and a deployed position, in which the slide 13 has slid until the primary stop plate 15 has come into contact with a second face 39 of the slide support 5, so as to block the translation of the slide 13 according to the first axis, in the vehicle's reversing direction.

The bicycle support 2 comprises a frame 40, provided with two longitudinal bars 41 and two transverse bars 42, so as to form a frame.

Each transverse bar 42 has a ramp 43, allowing the installation of a bicycle resting vertically on the ramp 43 by its wheel.

The longitudinal bars 41 are mounted in rotation relative to the two slides 13.

The longitudinal bars 41 pivot about an axis Y, with the slides 13, by means of two pivot axes 44.

The longitudinal bars 41, and consequently the frame 40, pivot between two positions:

an initial position, in which the longitudinal bars 41 extend along a longitudinal axis, and a deployed position, in which the longitudinal bars 41 have pivoted by an angle B (visible in FIG. 19).

The bicycle support 2 comprises a means for locking in rotation of the longitudinal bars 41, provided with two knobs screwing into the longitudinal bars 41 to prevent their rotation.

The two slides 13 include a flat 45, capable of blocking the rotation of the longitudinal bars 41 relative to the two slides

13.

The frame 40 comprises the two frame supports 26, mounted in rotation, around a longitudinal axis, with the transverse bars 42.

The frame supports 26 pivot between two positions:

an initial position, in which the frame supports 26 extend along the transverse axis, and a deployed position, in which the frame supports 26 have pivoted by an angle C (visible in FIG. 18).

The rotation of the frame supports 26 can be blocked, by means of two knobs screwing both into the frame supports 26 and the transverse bars 42.

As illustrated in FIG. 14 (top view), the bicycle support 2 is arranged in a first configuration, identical to the first configuration of the bicycle support 2, described above. As illustrated in FIG. 15, the means for blocking in translation of the slide 13 is active and an annex wheel 46 is screwed into the support 5 of the slide, so as to push back an annex key 47, so as to that it is in support of the slide 13 and blocks its translation by adhesion.

As illustrated in FIG. 16, the bicycle support 2 is arranged in a second configuration, identical to the second configuration of the bicycle support 2, described above.

The slides 13 have slid to their deployed position, as shown by the black arrows.

As illustrated in FIG. 17, the annex wheel 46 has been partially or completely unscrewed (as shown by the white arrow), and the annex key 47 has been slid to release the slide 13 and allow it to slide. , as shown by the black arrow.

As illustrated in Figure 18, the bicycle support 2 is arranged in a third configuration, in which the frame supports 26 have pivoted to their deployed position, as indicated by the black arrows.

In this third configuration, two bikes (shown in thin lines) are arranged vertically on the bike support 2, the rear wheels of the two bikes resting on the ramps 43 and the frames of the two bikes being integral with the frame supports 26 , by means of straps (not shown), the extensions 32 having slid in the supports 26 of the frame.

To pass the frame supports 26 in their deployed position, it was necessary to unscrew the knobs screwed into the frame supports 26, to release their rotation.

As illustrated in FIG. 19, the bicycle support 2 is arranged in a fourth configuration, in which the frame 40 has pivoted by angle B.

To rotate the frame 40 it was necessary to unscrew the knobs screwed into the longitudinal bars 41.

According to a third embodiment, illustrated in FIG. 20, the slides 13 are split into two parts 48, 49:

a fixed part 48, and a pivoting part 49, about a transverse axis, mounted in rotation with the fixed part 48 by means of an axis.

The fixed part 48 is pierced with two primary holes 50, 51, an upper primary hole 50 and a lower primary hole 51, the pivoting part 49 is pierced with a secondary hole 52, the primary holes 50, 51 make it possible to block the rotation of the pivoting part 49, in a position defined by a user.

The upper primary hole 50, when aligned with the secondary hole 52, makes it possible to position the pivoting part 49, so that it is aligned with the fixed part 48, the pivoting part 49 extending thus along an axis parallel to the X axis.

To completely secure the rotation of the pivoting part 49, a wheel is screwed into the secondary hole 52.

The lower primary hole 51 makes it possible to block the rotation of the pivoting part 49 in a position inclined by an angle E, as illustrated in FIG. 21.

The inclination of the pivoting part 49 of the slides 13 allows the bicycle support 2 to access a garage provided with a ramp, without the slides 13 coming into contact with this ramp and deteriorating.

According to a fourth embodiment, illustrated in FIG. 22, the support 2 for bicycles can be split into two elements:

a primary fitting 53, integral with the vehicle 1, also called hitch fitting, and a secondary fitting 54, embedded with the primary fitting 53 in a removable manner.

The secondary fitting 54 is mounted in rotation, around the Y axis, with a pivot 55, and this pivot 55 being mounted in rotation, around the Y axis, with the bicycle support 2, allowing the bikes arranged on the support 2 of bikes to tilt, so as to be able to access the boot of the vehicle and open this boot without interfering with the bike or bikes.

The bicycle support 2 described above has the following advantages:

it allows you to transport several bikes vertically on the vehicle hitch, mounting the bikes is quick and easy, it allows you to efficiently hold one or more bikes in position, it allows access to the trunk of a vehicle without having to dismantle the bicycle support 2.
