Description

RETRACTABLE BIKE SUPPORT ON VEHICLE COUPLING.

The invention relates to the field of vehicles, including automobiles. It relates, more specifically, the support of one or more bicycles by a bicycle carrier secured to a vehicle.

[0002] Today, the use of a bicycle is very varied, it is common for a bicycle user to travel outside the cities to practice off-road cycling or mountain biking, city streets and other roads. for vehicles already congested with motor vehicles, and the ground of the cities not corresponding to the use of an off-road bike or an ATV.

Thus, a user wishing to travel with his bike out of the cities will have to accommodate a means of transport for his bike, a bike being too bulky to easily be disposed in the trunk of a motor vehicle type city . Even if a bicycle that can be dismantled or folded in any way could be arranged in the trunk of a motor vehicle, this motor vehicle could not carry several bicycles.

In addition, it is also common to take one or more bikes (city bikes, off-road or mountain bike) when departing on a trip. Whether they are city, off-road or mountain bikes, the need is the same: to carry one or more bikes with a vehicle. It is known to use a bike carrier attached to a motor vehicle, to meet the need cited above.

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

- roof bike racks,

- the tailgate bike carriers,

- bike carriers on hitch.

Roof bike carriers consist of two distinct parts: the roof bars, which are fixed on the roof of a vehicle, and the bike carrier, which is fixed on these roof bars. This type of bicycle carrier has the advantage of providing a good fixation of the bicycles, it ensures a good security as to the position of the bicycles on the roof of a vehicle.

However, roof bike carriers have the disadvantage of not being ergonomic in that it is difficult to place the bikes on the roof of a vehicle, especially if the vehicle has a height important roof. In addition, a vehicle equipped with such a bicycle carrier and supporting one or more bicycles can access all limited access spaces by a defined vehicle height. In addition, the bicycle or bikes on the roof affect the aerodynamics of the vehicle, increasing fuel consumption.

Tailgate carriers consist of a frame, secured to a hatch with straps, the frame includes a fork to receive one or more bicycles. This type of bike carrier has the advantage of being quickly mountable on the tailgate of a vehicle.

[0009] Nevertheless, the tailgate bicycle carriers have the disadvantage of not being able to adapt to any type of vehicle. Indeed, this type of bicycle carrier can not be mounted on a hatch comprising a composite material or a shutter consisting only of a window. In addition, the fixing system of this type of bike carrier is not completely reliable in that it can support a limited amount of bicycles without causing the possible detachment of the bike carrier of the tailgate, because of the weight of bicycles.

The bike carriers on hitch consist of a hitch, a hitch ball for example, and a frame supporting several bikes. This type of bike carrier has the advantage of being robust and ergonomic. Bikes are easily put in place and held in position with this type of bike rack.

However, bike carriers on hitch means have the disadvantage of hiding 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.

EP2134571 discloses a bicycle carrier intended to be positioned on the coupling of a vehicle, the bicycle carrier being able to extend, by a longitudinal translation guided through the bumper of the vehicle, and more particularly under the bumper, at the base of the vehicle. The bicycle rack includes a means of tilting the bicycles, allowing access to the trunk of the vehicle.

However, this bicycle carrier has the disadvantage of hiding the rear visibility of the driver, when bikes are arranged on the bicycle rack. The device also hides the rear lights of the vehicle and its license plate. .

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

A second objective is to provide a bicycle rack that does not hide the rear visibility of the driver, or the lights or the license plate of a vehicle.

A third objective is to provide a bicycle holder ensuring a maintenance position of bicycles.

For this purpose, it is proposed, in the first place, a bicycle carrier intended to be mounted on a vehicle, this bicycle carrier comprising:

- Two slide supports, intended to be mounted on a vehicle coupling type fitting;

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

a frame support, intended to support, when the two slides are in an extended position, a bicycle frame, this frame support is mounted with one of the two slides between two positions:

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, wherein the frame support extends along a third axis, the first axis and the third axis being in a second plane, distinct from the first plane.

Advantageously, such a support makes it easy to hang one or more bikes on a motor vehicle.

This support, when not in use and that the slides are in the initial position, is compact, so as to fit completely under the vehicle, at its base.

[0020] Various additional features may be provided, alone or in combination: the bicycle rack comprises two wheel supports, linked to the slides;

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

the bicycle carrier comprises a locking means in translation, for preventing the sliding of the two slides in the two slide supports, this translational locking means comprising:

two locking keys in translation, sliding in a secondary bore dug both in the base and partly in the slide supports,

o a main wheel, screwing into a bore made in the base, so as to push the locking keys in translation against the slideways, the bore opening into the secondary bore;

two locking keys in translation, sliding in a secondary bore dug both in the base and partly in the slide supports, the locking keys in translation comprising racks extending at their end,

o a main wheel, having a toothed portion adapted to mesh with the racks;

the bicycle carrier comprises rotational locking means for preventing pivoting of the slide supports, said rotational locking means comprising:

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

the bicycle carrier comprises an armature, comprising two longitudinal bars with respect to the two slides and two longitudinal bars with respect to the two slides, the frame support being mounted in rotation, with the transverse bars, around an axis parallel to the first axis; ;

the two slides are split into a fixed part and a pivoting part relative to the fixed part, about an axis transverse to the two slides;

the bicycle carrier further comprises a primary fitting, intended to be fixed to a vehicle coupling fitting, and a secondary fitting, connected to the primary fitting, the secondary fitting being rotatably mounted relative to the two slides, around an axis transverse to the two slides.

It is proposed, secondly, a motor vehicle comprising a hitch and the bike carrier as presented above.

In Figure 1 is shown a vehicle 1 (in dashed lines), comprising a support 2 of bicycles (in continuous bold lines) disposed near a base 3 of the vehicle 1, the support 2 of bicycles being more particularly secured to the trailer coupling of the vehicle 1.

The vehicle 1 may for example be a particular motor vehicle or utility. One defines with respect to the vehicle 1 an orthogonal reference XYZ comprising three axes perpendicular two by two, namely:

an axis X, defining a longitudinal direction, horizontal, coincides 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 remainder of the 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 carrier 2 of bicycles comprises a base 4 secured to the hitch coupling.

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

The slideway supports 5 are profiles having a parallelepipedal shape in section, these profiles extend in a L-shaped shape forming a bearing surface 7.

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

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

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

The support 2 of bicycles comprises two slides 13 having a parallelepiped shaped section, the two slides 13 each comprising, at a first end 14, a plate 15 of primary stop, and comprising, at a second end 16, a edge 17. The slides 13 slide in the brackets 5 of slides between two positions:

an initial position, in which the slide supports 5 rest on the flanges 17 of the slideways, so as to block the translation of the slideways 13 along a first longitudinal axis, and

an extended position, in which the slides 13 have slid until the primary stop plates 15 have come into contact with the support surfaces 7 of the slide supports 5, so as to block the translation of the slides 13 according to 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).

[0036] The translation blocking means 18 comprise two locking keys 19 in translation, sliding in a secondary bore 20, hollowed both in the base 4 and partly in the slideway supports 5, the secondary bore 20. extending along an axis parallel to the Y axis.

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

The support 2 of bicycles comprises two wheel supports 23, rotatably mounted 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

an extended position, in which the wheel supports 23 extend along a longitudinal axis.

The wheel supports 23 each comprise two hooks

24, fit to receive a wheel of a bicycle.

The wheel supports 23 allow to position the wheel of a bicycle, so as to hold it in a vertical position.

The rotation of the wheel supports 23 can be locked by means of two secondary wheels 25, screwing into both the wheel supports 23 and the slides 13. The carrier 2 of bicycles comprises two frame supports 26, rotatably mounted 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 rotatably mounted 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,

an extended position in which the frame supports extend along a vertical axis.

The rotation of the frame supports 26 can be blocked by means of two tertiary wheels 27, screwing into both the frame supports 26 and the slides 13.

As illustrated in FIG. 3, the support 2 for bicycles is arranged, according to a first configuration, in which the support 2 for bicycles is placed under the vehicle 1, at its base 3. The support 2 of bicycles 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 carrier 2 of bicycles is arranged according to its first configuration, described above.

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

Thus, the locking keys 19 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 locking pins 9 in rotation and in support of primary flanges 29 extending from the locking pins 9 rotating. Thus, the locking keys 9 rotational prevent the rotation of the slide supports 5.

In this configuration, the primary return springs 28 are relaxed.

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

In this configuration, the main knob 21 has been unscrewed in part or completely, as shown in Figure 6 by a white arrow.

When the main knob 21 has been unscrewed, the keys

19 locking in translation slid into the secondary bore.

Indeed, two secondary return springs 30, wound around the locking keys 19 in translation, bearing on secondary collars 31 extending from the lock keys 19 in translation (as shown by the black arrows of the Figure 6) have pushed the locking keys 19 in translation.

The secondary return springs are moved from a compressed state to a relaxed state.

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

As illustrated in FIG. 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 black arrows.

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

The frame supports 26 each comprise a sliding extension 32 inside the frame supports 26.

The extensions 32 are held in position by means of screws 33. In other words, the frame supports 26 are telescopic.

These extensions make it possible to adjust the support 2 of bicycles to the height of the bicycles, so as to support the frame of the bikes, the extensions 32 including a means 34 of support for the frame of the bicycles. As illustrated in FIG. 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 black arrows.

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

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

As illustrated in FIG. 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 brackets 5 slides, disarm the locking means 8 rotated, it is necessary to pull the handle 11 (as shown by a black arrow in Figure 10), to slide the keys 9 of rotational locking in the primary bores, so that the locking keys 9 rotate only in the base portion 4 of the primary bores 10 (as shown by a black arrow in Figure 10).

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

The pivoting brackets 5 slides advantageously to incline two bikes (shown in bold lines), arranged vertically on the support 2 of bicycles, the rear wheels of the two bikes being arranged on the hooks 24 and the frame of both bicycles resting on the support means 34, so as to open the trunk of the vehicle 1, without having to remove the bikes from the support 2 of bicycles or without having to dismount the bicycle stand 2 itself.

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

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

The support 2 for bicycles comprises the slides 13 previously described, which each comprise the plate 15 of primary abutment, and a plate 37 of secondary abutment.

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

an initial position, in which the secondary stop plate 37 is in abutment with 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

an extended position, in which the slide 13 has slid until the primary stop plate 15 is brought into contact with a second face 39 of the slide support 5, so as to block the translation of the slides 13 according to the first axis, in the direction of recoil of the vehicle.

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

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

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

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

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

an initial position, in which the longitudinal bars 41 extend along a longitudinal axis, and

an extended position, in which the longitudinal bars 41 have pivoted by an angle B (visible in FIG. 19).

The support 2 of bicycles comprises a locking means in rotation of the longitudinal bars 41, provided with two knurls screwing in the longitudinal bars 41 to prevent their rotation. The two slides 13 comprise a plate 45, able to block the rotation of the longitudinal bars 41 relative to the two slides 13.

The frame 40 comprises the two frame supports 26, rotatably mounted 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

an extended 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 locked by means of two knurls screwing into both the frame supports 26 and the transverse bars 42.

As illustrated in Figure 14 (top view), the carrier 2 of bicycles is arranged in a first configuration, identical to the first configuration of the support 2 bicycles, described above.

As illustrated in Figure 15, the blocking means in translation of the slide 13 is active and an adjuster wheel 46 is screwed into the support 5 slide, so as to push a key 47 annex, so as to it is in support of the slide 13 and blocks its translation by adhesion.

As illustrated in Figure 16, the carrier 2 of bicycles is arranged in a second configuration, identical to the second configuration of the carrier 2 of bicycles, described above.

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

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

As illustrated in FIG. 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 black arrows.

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

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 Figure 19, the support 2 of bicycles is arranged in a fourth configuration, wherein the armature 40 has rotated the angle B.

To rotate the armature 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 portion 48, and

a pivoting portion 49 about a transverse axis rotatably mounted with the fixed portion 48 by means of an axis.

The fixed portion 48 is pierced with two primary holes 50, 51, an upper primary hole 50 and a lower primary hole 51, the pivoting portion 49 is pierced with a secondary hole 52, the primary holes 50, 51 allow blocking the rotation of the pivoting portion 49 in a position defined by a user.

The upper primary hole 50, when aligned with the hole

52, allows positioning the pivoting portion 49 so that it is aligned with the fixed portion 48, the pivoting portion 49 thus extending along an axis parallel to the axis X.

To completely secure the rotation of the pivoting portion 49, a knob 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 portion 49 of the slides 13 allows the support 2 of bicycles to access a garage with a ramp, without the slides 13 come into contact with this ramp and deteriorate.

According to a fourth embodiment, illustrated in FIG. 22, the bicycle support 2 can be split into two elements: a primary fitting 53 secured to the vehicle 1, also called a coupling bracket, and

a secondary fitting 54, recessed with the primary fitting 53 in a removable manner.

The secondary fitting 54 is rotatably mounted about the Y axis, with a pivot 55, and this pivot 55 being rotatably mounted about the Y axis, with the support 2 of bicycles, allowing the bicycles arranged on the support 2 of bicycles to bow, so as to access the trunk of the vehicle and open the trunk without interfering with the bike or bikes.

[00105] The bicycle support 2 described above has the following advantages:

it allows to transport several bikes vertically on the vehicle hitch fitting, the mounting of the bikes is easy and fast, it can effectively maintain in position one or more bikes,

it allows access to the trunk of a vehicle without having to disassemble the support 2 of bicycles.
