Description

Title of the invention: FREE-span basket-type car stacker Technical field

[0001] The present invention relates to the general technical field of car transport convoys, more precisely car transporters.

[0002] The invention relates in particular to a car stacker, intended to be pivotally mounted on the chassis or on a loading platform of a car-carrying vehicle. Such a stacker may also be called a "loading platform".

[0003] The stackers advantageously allow the attitude of the cars they support to be adjusted, in order to be able to nest said vehicles as best as possible and thus increase the loading capacity of the car transporter. State of the art

[0004] Car carrier vehicles comprising loading platforms are already known. A stacker is therefore known for supporting two wheels of at least one axle of a car and mounted on a car carrier vehicle. The stacker comprises two lateral side members mechanically connected to each other by transverse elements in the vicinity of at least a first or a second end zone of the pair of side members.

[0005] The first end zone is for example associated with an articulation system for pivoting the stacker relative to the vehicle along a horizontal pivot axis transverse to said vehicle, the articulation system being associated with a drive system making it possible to tilt by pivoting and maintain said stacker in position.

[0006] The second end zone located at a free end of the stacker comprising a basket-type cross member which connects the two side members, this basket-type cross member being mounted to be movable along the side members, said basket-type cross member comprising a basket at each of its lateral ends, these two baskets being located between the two side members and each formed by a receiving niche into which the wheels of the axle sink and are wedged in the transport position,

[0007] The basket-type cross member can be moved manually or hydraulically and when in the desired longitudinal position on the side members, it is locked onto said side members.

[0008] The basket-type crosspiece is for example moved and locked using a jack central hydraulic. The latter is then equipped with a safety block to hold the basket-type cross member in position. This is not without consequences on the manufacturing costs of such a stacker. In addition, the central position of the hydraulic cylinder on the stacker does not allow the space between the first end zone and the second end zone to be completely freed. This space cannot therefore be occupied by part of another vehicle in the transport position. The nesting of the vehicles is therefore not optimal.

[0009] On a manual basket-type sleeper with a claw lock, locking is achieved using two locking members located at the ends of said sleeper. These locking members, for example projecting locking claws, cooperate mechanically with holes provided on the side members. These claws must be moved manually by the operator, against a restoring force of a spring. Such an operation may prove uncomfortable to carry out and dangerous for the operator.

[0010] Another example of an embodiment of a stacker is for example described in patent EP 3 687 856. The cross member is equipped with translation pinions whose teeth fit into corresponding holes provided on the side members. A drive system makes it possible to synchronize the rotation of the pinions so that the cross member is moved longitudinally on the side members. Such a solution increases the weight of the stacker and presents high manufacturing costs.

[0011] When the stacker or stacker is designed to support only one axle (single-axle stacker), the operator is faced with an additional problem with the known solutions of the prior art. Indeed, the locking of the basket-type basket crossmember on the stacker requires leaving the axle which remains supported on the chassis of the vehicle, free in translation during a stacking operation. During the tilting of the stacker, the axle supported on the chassis of the vehicle will move forward or backward, which is a major drawback because the final position of the car must be anticipated precisely. There is therefore a greater risk of collision between loaded / nested cars or at best a non-optimal distribution of the cars in the loading space.

[0012] Furthermore, for a stacker having a claw basket-type crossmember, if the final loading position is not suitable when the car is stacked (tilted), the operator must unload the car to reposition the claw basket-type crossmember. This can substantially increase the time required to load the cars. Description of the invention

[0013] The object of the invention therefore aims to overcome the drawbacks of the prior art by proposing a new stacker comprising at least one basket-type crosspiece and the use of which is easy and simplified.

[0014] Another object of the invention is to provide a lighter, more reliable and economical stacker.

[0015] Another object of the invention is to provide a stacker, which makes it possible to simplify loading / stacking operations for the operator and to make said operations safer.

[0016] The objects assigned to the invention are achieved using a stacker intended to support two wheels of at least one axle of a car and intended to be mounted on a car-carrying vehicle, comprising: - two lateral side members mechanically connected to each other by a transverse element in the vicinity of a second end zone of the pair of side members, - a first end zone comprising an articulation system for pivoting the stacker relative to the vehicle along a pivot axis horizontal and transverse to said vehicle, the articulation system being associated with a drive system for tilting by pivoting and holding said stacker in position, - the second end zone located at a free end of the stacker comprising a basket-type cross member which connects the two side members, this basket-type cross member being able to occupy different longitudinal positions on the side members, said basket-type cross member comprising a basket at each of its lateral ends, these two baskets being located between the two side members and each being formed by a receiving niche in which a wheel of the axle engages and is wedged in the transport position, characterized in that the basket-type cross member is mounted to slide freely on the two side members, so as to be able to move freely between a proximal position, close to the first end zone and a distal position distant from the first end zone.

[0017] According to an exemplary embodiment, the drive system comprises two actuators, each of which is articulated between one of the side members and the vehicle to modify the inclination of said stacker.

[0018] The stacker is for example intended to be articulated on a vehicle chassis.

[0019] According to another exemplary embodiment, the stacker is intended to be articulated on a loading platform mounted fixed or mobile on the vehicle chassis.

[0020] According to an exemplary embodiment, each side member comprises a first side member portion hinged at one end to the vehicle and a second side member portion hinged to the first portion via a transverse axis pivot connection. The first side member portion comprises an end portion located beyond the transverse axis pivot connection and constitutes or comprises a vertical support for the second portion. Advantageously, the basket-type cross member is mounted on the second side member portion and the drive system is associated with the first side member portion.

[0021] According to an exemplary embodiment, the stacker comprises, on the one hand, sliding members for sliding, longitudinal guiding and lateral guiding of the basket-type crossmember on the side members and, on the other hand, articulation members for pivoting upwards the basket-type crossmember from an extension plane defined by the side members. The basket-type crossmember is therefore a free liftable crossmember.

[0022] According to an exemplary embodiment, the first end zone comprises a transverse element in the form of a deck provided to support wheels of a second axle of the car, the wheels of the first axle being wedged in the baskets of the basket-type crossmember of the second end zone.

[0023] According to another exemplary embodiment, the first end zone comprises another fixed basket-type crossmember, provided to support the wheels of a second axle of the car, the wheels of the first axle being wedged in the baskets of the basket-type crossmember of the second end zone.

[0024] According to another exemplary embodiment, another basket-type crossmember is slidably mounted on the side members in the first end zone and said other basket-type crossmember is associated with locking members for locking said other basket-type crossmember on the side members when the optimal position is reached.

[0025] The stacker according to the invention is advantageously a double-axle stacker or a single-axle stacker.

[0026] The objects assigned to the invention are also achieved using a car-carrying vehicle comprising at least one stacker as presented above.

[0027] The stacker or stacker according to the invention, in its single-axle configuration, has the remarkable advantage that it avoids during the stacking operation having to move the axle forward or backward while resting on the chassis of the vehicle. The position of this axle and consequently the position of the corresponding car is therefore anticipated with precision. The operator can thus apply the wheel brake before stacking and therefore does not have to get into the car after stacking (car inclined) to apply the brake.

[0028] Another advantage of the stacker or stacker according to the invention lies in the simplicity of its manufacture. The stacker is in fact devoid of any complex and expensive mechanical or hydraulic drive system. The weight of such a stacker is consequently lower due to the absence of a drive or locking system for the crossbar.

[0029] The configuration of the stacker according to the invention makes it possible to present a completely clear and accessible central space.

[0030] Another advantage is linked to the speed of positioning the basket-type crossbar on the stacker according to the invention. Such positioning is carried out in less than one minute.

[0031] The fact that the free crossbar can be lifted, unlike known platforms with a central jack or locking claws, means that the stacker no longer needs to perfectly match the shape of the decking on which it rests. The design of the stacker is therefore simpler.

[0032] With the stacker according to the invention, it is possible to strap the car before starting to stack the platform, which is much more ergonomic for the operator, particularly if the final position is very high. Brief description of the drawings

[0044] Structurally and functionally identical elements present in several distinct figures are assigned the same numerical or alphanumeric reference.

[0045] By car, we mean here any four-wheeled vehicle, usually transported on a car carrier.

[0046] Longitudinal refers to a direction corresponding to the usual direction of movement of car transporters and cars for their loading, while transverse refers to a horizontal direction and orthogonal to the longitudinal direction.

[0047] The invention relates to a stacker intended to support the two wheels of at least one axle of a car.

[0048] By decking is meant a substantially horizontal assembly of metal sheets or plates, allowing the passage of cars 3 and usually shaped with perforations.

[0049] By basket-type crossmember is meant a transverse part designed to receive each of the two wheels of the same axle or set of wheels of a car in a basket, each of these two baskets being formed by a receiving niche into which the wheels partially sink and are wedged in the transport position.

[0050] The basket-type crossmember comprises a basket at each of its lateral ends, these two baskets being located between the two side members and connected by a transverse element.

[0051] The receiving niche of each basket can be formed by a recess shaped in the basket-type crossmember, the basket then having an open bottom, or by a concave deformation shaped downwards in the basket-type crossmember, the basket then having a closed bottom. Each basket preferably has a (transverse) width greater than the width of a wheel in order to be able to adapt to the dimensions of any type of car to be carried on the stacker.

[0052] Each basket also preferably has a (longitudinal) length less than the usual minimum diameter of a wheel so that the wheels of a car carried on the stacker cannot pass entirely through the baskets but are retained by the longitudinal edges of each basket.

[0053] Each basket is preferably in the form of two transverse wheel supports connected to each other by two longitudinal edges parallel to the side members. Each basket is preferably trapezoidal in shape, the shorter side of each trapezoid being directed towards the inside of the stacker. Indeed, small cars are generally narrow-track and have small wheels. The trapezoid shape is also favorable for improving the embedding of a generally curved windshield.

[0054] [Fig. 1] is a schematic view of a first embodiment of a single-axle stacker 1 according to the invention, in a loading position pivoted upwards from a loading platform 2.

[0055] The stacker 1 has a first end zone comprising an element transverse stiffening member, for example a rigid cross member, of the stacker 1. The stacker 1 is associated with an articulation system 3 for pivoting the stacker 1 relative to the vehicle along a horizontal pivot axis transverse to said vehicle. The articulation system is for example integrated into the platform 2 or into a chassis of the vehicle.

[0056] The articulation system 3 is associated with a drive system not shown for tilting by pivoting, for example upwards and for holding said stacker 1 in position. The latter supports for example the front axle of a car 4.

[0057] The stacker 1 has a second end zone 1b located at a free end of said stacker 1. The second end zone 1b comprises a basket-type cross member 5 which connects the two side members. This basket-type cross member 5 can occupy different longitudinal positions on the side members.

[0058] The basket-type crossmember 5 advantageously comprises a basket at each of its lateral ends, these two baskets being located between the two side members and each of said baskets is formed by a receiving niche in which a wheel 4a of the axle engages and is wedged in the transport position.

[0059] The basket-type crossmember 5 is mounted to slide freely on the two side members, so as to be able to move freely between a proximal position, close to the first end zone 1a and a distal position distant from the first end zone 1a. The basket-type crossmember 5 therefore has a free sliding travel CL at the level of the second end zone 1b. The basket-type crossmember 5 is therefore not locked in position, even during the rolling phases.

[0060] [Fig. 2] is a schematic view of a second embodiment of the stacker 1, in a loading position. In this embodiment, the stacker 1 constitutes a double-axle stacker and the transverse element of the first end zone 1a comprises a deck 6 for supporting the wheels 4b of a second axle of the car 4. The wheels 4a of the first axle are wedged in the baskets of the basket-type crossmember 5 of the second end zone 1b.

[0061] [Fig. 3] is a schematic view of a third embodiment of the stacker 1, in a loading position. In this embodiment, the stacker 1 constitutes a double-axle stacker and the transverse element of the first end zone 1a comprises another basket-type crossmember 7 provided to support the wheels 4b of the second axle of the car 4. The wheels 4a of the first axle are also wedged in the baskets of the basket-type crossmember 5 of the second end zone 1b.

[0062] The other basket-type cross member 7 is advantageously slidably mounted on the side members of the stacker 1, in the first end zone 1a. In addition, the other basket-type cross member 7 is associated with locking members for locking said other basket-type cross member 7 on the side members when the optimal and / or desired position of the car 4 is reached.

[0063] [Fig.4] is a schematic and kinematic illustration of an example configuration of a single-axle stacker 1. The platform 2 has, for example, a three-part configuration, including an inclined part connecting two substantially horizontal parts.

[0064] The articulation system 3 allows the stacker 1 to pivot downwards while the basket-type crossbar 5 pivots upwards when the free end of said basket-type crossbar 5 rests on the platform. The stacker 1 can thus extend in a direction of the inclined part of the platform 2.

[0065] The stacker 1 advantageously comprises sliding members 8 and articulation members 9.

[0066] The sliding members 8 are designed to provide longitudinal guidance and lateral guidance of the basket-type crossmember 5 when it slides on the side members.

[0067] The articulation members 9 are designed to allow upward pivoting of the basket-type cross member 5 from an extension plane defined by the side members.

[0068] [Fig. 5] is another partial perspective view of an exemplary embodiment of a single-axle stacker 1 mounted on a loading platform 2. The platform 2 is for example made up of successive decks 10, 11 and 12, mounted fixed or mobile on a chassis 13 of a vehicle.

[0069] The stacker 1 comprises two side members 14 mechanically connected to each other by a transverse element at least in the second end zone 1b. This transverse element is constituted by the basket-type cross member 5 which comprises, in a known manner, two baskets 16 intended to receive and wedge the wheels 4a of the first axle of the car 4.

[0070] The side members 14 are articulated directly on each lateral side of the chassis 13 at the level of the first end zone 1a, thanks to the articulation system 3. The side members 14 advantageously have a bent or straight shape depending on the configuration of the platform 2. The stacker 1 is therefore devoid of any transverse element at the level of the first end 1a, thus freeing up all the central space and contributing to the reduction of the weight of said stacker 1.

[0071] The articulation system 3 is associated with a drive system, for example hydraulic, for tilting by pivoting and for holding the stacker in position, loaded or not. The drive system advantageously comprises two hydraulic, pneumatic or electric actuators 17, each of which is articulated between one of the side members 14 and the chassis 13 of the vehicle to modify the inclination of the stacker 1.

[0072] [Fig.6] is a perspective view of a portion of the basket-type crossmember 5 of the stacker and [Fig.7] is a top view of a portion of the basket-type crossmember 5.

[0073] [Fig.8] is a profile view of the free end of an exemplary embodiment of the stacker 1, the basket-type crosspiece 5 of which is pivotable upwards and [Fig.9] is a profile view in longitudinal section of the free end of the stacker 1.

[0074] In addition, [Fig. 10] is a cross-sectional view of a side member 14 partly illustrating the sliding members 8 and the pivoting members 9 of the stacker 1.

[0075] The side members 14 are advantageously mechanically welded structures of sheets of different dimensions and shapes. Each side member 14 comprises a rigid assembly of an inner wall 18 whose upper edge 18a is free and an outer wall 19. The inner wall 18 is longer than the outer wall 19. The latter has a curved upper end 19a folded towards the inner wall 18 so as to partially cover the free space 14a located between the inner 18 and outer 19 walls.

[0076] Connecting elements 20 make it possible to connect the inner 18 and outer 19 walls by welding.

[0077] The basket-type crosspiece 5 has on each lateral side a profile 15a in the shape of an inverted U which covers the upper edge 18a of the inner wall 18. The profile 15a therefore rests on the upper edge 18a, which forms the vertical support zone on the side member 14. The inverted U-shaped profile therefore has two branches 21 and 22 of the inverted U, which are positioned on either side of the inner wall 18 when the profile 15a rests on the upper edge 18a. The inverted U-shaped profile 15a, covering the upper part of the inner wall 18, thus makes it possible to ensure the sliding guidance and the lateral guidance of the basket-type crosspiece 5 on the side members 14. The profile 15a and the inner wall of the side member 14 thus form the sliding members 8.

[0078] The branch 21 of the profile 15a, which is located between the inner 18 and outer 19 walls, is provided with a retaining member 23, for example a welded round, which extends transversely towards the outer wall 19. The retaining member 23 extends into the free space 14a and under the curved upper end 19a. The retaining member 23 is thus retained vertically by the side member 14, which prevents any possible vertical disengagement of the basket-type cross member 5 from the side member 14.

[0079] The retaining member 23, by its specific position, that is to say at one of the ends of the basket-type crosspiece 5, makes it possible to ensure the upward pivoting, according to the arrow P, of the basket-type crosspiece 5.

[0080] The support zone in the non-pivoted position of the basket-type crossmember 5 is the upper edge 18a, i.e. the contact surface (18a, [Fig.10]) between the sheets of the side member 14 and the basket-type crossmember 5. In the pivoted position, upwards, the support zone becomes the end of this contact surface, more precisely the edge or end of the profile 15a. This edge thus constitutes the pivot axis and the retaining member 23 pivots around this axis when the basket-type crosspiece is lifted.

[0081] The position of the retaining member 23 on the branch 22, at least further forward relative to the pivot axis constituted by the end of the profile 15a resting on the edge 18a, allows the basket-type crosspiece 5 to pivot, while maintaining the upward retaining function of said basket-type crosspiece 5. This is to ensure that the basket-type crosspiece does not disengage from the side members 14.

[0082] The side members 14 further comprise a safety stop 24 to delimit the extreme longitudinal position of the basket-type cross member 5 on said side members 14. The safety stops 24 prevent longitudinal disengagement of the basket-type cross member 5 from the side members 14.

[0083] For example, the single-axle stacker 1 also has a substantial advantage in that it simplifies the loading / unloading process. In fact, the operator positions the basket-type crossmember 5 on the side members 14, loads the car 4, applies the handbrake of the car 4, stacks the car 4 with the handbrake applied, wedges and straps the axle resting on the platform 2 and then straps the axle resting on the basket-type crossmember 5.

[0084] Unlike a process known in the prior art, the operator does not have to lock the basket-type cross member 5 onto the side members 14. Furthermore, the fact of being able to apply the brake of the car 4 before it is stacked avoids the operator having to get back into the car 4 once stacked to apply said brake. Such an operation is often complicated or even dangerous due to the height and the inclination of the stacked car 4.

[0085] According to an exemplary embodiment, illustrated in particular in [Fig. 10], each side member 14 comprises a first part 14a articulated by one end on the vehicle or on the platform 2 and a second part 14b articulated on said first part 14a. This articulation is achieved by means of a pivot connection with a transverse axis 14c.

[0086] The first part 14a comprises an end portion 14d, located beyond the transverse axis pivot connection 14c. This end portion 14d constitutes or comprises a vertical support for the second part 14b. The second part 14b is held in position relative to the first part 14a by resting on this end portion 14d when the stacker 1 is pivoted upwards. The second end zone 1b is located towards the free ends of the second parts 14b.

[0087] The actuator 17 is advantageously articulated on the one hand on the platform 2 and on the other hand on the first part 14a to move the first part 14a by pivoting while driving the second part 14b in its movement. When the actuator 17 brings the first part 14a down onto the platform 2, the second part 14b rests on the platform 2 and can be lifted from the vertical support of the end portion 14d. The stacker 1 can thus adapt as best as possible to the configuration of the platform 2.

[0088] It is obvious that the present description is not limited to the examples explicitly described, but also includes other embodiments. Thus, a described technical characteristic could be replaced by an equivalent technical characteristic, without departing from the scope of the present invention as defined by the claims.
