    Tilting trailer comprising mechanical actuation means and locking means in the high position
    1. FIELD OF THE INVENTION
    The field of the invention is that of tilting trailers.
    More specifically, the invention relates to a tilting trailer allowing a user to load and unload bulky and heavy objects alone such as motorcycles, household appliances, garden machinery (for example a ride-on mower, a mini tractor) , etc ...
    2. TECHNOLOGICAL BACKGROUND
    In the state of the art, various types of trailer are known which allow a single person to load and unload bulky and heavy objects, using a hand truck.
    For example, in document US Pat. No. 5,975,828, such a trailer is proposed comprising a drawbar mounted integrally with the chassis of the trailer, as well as a system for tilting the chassis.
    Such a tilting system comprises a single cable attached to the center of an axle, controlling the tilting or lifting of the chassis depending on the tension exerted on the cable.
    Another drawback of this known solution is that the cable being mounted in the center of the axle, it tends to deform when the cable is stretched and a heavy load is positioned on the trailer.
    Yet another drawback of this known solution is that the management of the cable tension is carried out by an electronic device which requires an electrical supply.
    Yet another drawback of this known solution is that the cable tension must often be checked in order to prevent inadvertent tilting of the chassis, in particular when driving.
    Yet another drawback of this known solution is that braking means must be used to slow down the speed at which the lowering of the chassis takes place.
    Other techniques presented in documents US2006 / 0045693, US2012 / 0020762, US 2005/0067799, IE 2006/0467 have been developed.
    However, these techniques also have drawbacks similar to those explained above.
    In addition, these techniques are relatively complex to implement and require numerous modifications to be made to a conventional trailer.
    Furthermore, some of them implement a jack controlling the movement of the chassis relative to the ground, which increases the manufacturing costs of the trailer.
    3. OBJECTIVES OF THE INVENTION
    The invention, in at least one embodiment, aims in particular to overcome these various drawbacks of the state of the art.
    More specifically, in at least one embodiment of the invention, an objective is to provide a trailer which complies with European road safety standards.
    Another objective of at least one embodiment of the invention is to provide such a trailer whose manufacturing cost is relatively low.
    Another objective of at least one embodiment of the invention is to provide such a trailer which can implement a standard axle sold commercially.
    At least one embodiment of the invention also aims to provide such a trailer making it possible to lower a chassis with a slight slope, of the order of 3 to 5 degrees relative to the ground.
    Another objective of at least one embodiment of the invention is to provide such a trailer which can tilt or stand up quickly.
    An additional objective of at least one embodiment of the invention is to provide such a trailer making it possible to tilt its loading platform which is not abrupt.
    4. STATEMENT OF THE INVENTION
    For this, the invention relates to a tilting trailer that can take a high position, or road, and a low loading position, the trailer comprising a chassis resting on the ground by wheels, the chassis being mounted on an axle pivotable with respect to said wheels.
    According to the invention, the trailer further comprises:
    - Means for actuating the pivoting of said axle relative to the wheels so as to vary the position of said chassis relative to the ground, said actuating means comprising at least one flexible element integral with said axle and a device for adjusting the tension said flexible element fixed to said chassis, and
    - Trailer locking means in the high position, separate from the actuation means.
    Thus, a tilting trailer is proposed in which the lifting and lowering system of the platform comprises a flexible element, such as a cable or a strap attached to the axle, controlling the pivoting of the latter and the movements of the chassis depending on the tension exerted on the cable or strap.
    The expression "flexible" is opposed here to "rigid", and therefore supposes an ability of the cable or strap to tighten or relax, that is to say to be more or less tense.
    Advantageously, the management of the tension of the cable or of the strap is carried out by a mechanical device, such as a winch or a ratchet tensioner respectively, inexpensive.
    Furthermore, the trailer implements means for locking the trailer in the high position, distinct from the means controlling the lifting and lowering of the trailer.
    In this way, an untimely lowering of the chassis is prevented, in particular when driving.
    These locking means make it possible to reduce the mechanical stresses on the axle in the high position of the trailer and the wear of the cable or the strap.
    The solution of the invention does not require the implementation of a jack and therefore proves to be less expensive.
    According to a particular aspect of the invention, said flexible element is a strap and said tension adjustment device is a ratchet tensioner.
    According to a particular aspect of the invention, said flexible element is a cable and said tension adjustment device is a winding winch for said cable.
    These two implementation alternatives are reliable, not very complex and economical.
    According to a particular aspect of the invention, said locking means comprise a sliding locking bar, a first end of which is integral with said axle and a second end intended to cooperate with a locking mechanism, mounted on said chassis, when the trailer in position high.
    The locking bar reduces the stress on the axle when the cable or strap is tensioned in the high position of the trailer.
    According to a particular aspect of the invention, said chassis comprises a first frame, said rear frame, pivotally connected to a second frame, said front frame, so as to allow folding of said trailer.
    This reduces the size of the trailer to store it in a garage, for example.
    According to a particular aspect of the invention, the rear frame of the chassis is connected to the front frame by means of connection means located on each side of said trailer, said connection means carrying a pivot axis of the rear frame relative to the frame before.
    According to a particular aspect of the invention, said connecting means have a space located between said rear and front frames, intended to receive said axle when the trailer is in the low position.
    According to a particular aspect of the invention, the trailer further comprises a retractable stand mounted on said chassis.
    Such a stand ensures the vertical maintenance of the trailer when the trailer is in the storage position, that is to say when the front and rear frames of the chassis are folded down opposite one another.
    According to a particular aspect of the invention, the trailer comprises a drawbar carrying a coupling arrow secured to said chassis by means of a pivot link enabling the drawbar to be folded down relative to said chassis.
    This possibility of folding the drawbar makes it possible to reduce the size of the trailer, in particular in the storage position.
    According to a particular aspect of the invention, the trailer comprises suspension means located inside said axle.
    These suspension means, such as rubber elements, make it possible to improve the stability of the trailer.
    According to a particular aspect of the invention, said axle comprises an outer tube in which is mounted an inner tube, each of the ends of which is secured to a wheel, the chassis being secured to the outer tube.

    6. DETAILED DESCRIPTION
    In all the figures in this document, identical elements are designated by the same reference numeral.
    Furthermore, the terms “front” and “rear” take as a reference the direction of advance of the towing vehicle.
    Figures IA and IB are perspective views of a tilting trailer according to a particular embodiment of the invention respectively in road position (also called high position) and in said loading position (also called low position).
    More specifically, the trailer 100, in this embodiment of the invention, is provided with a chassis 101 in two parts, namely a rear chassis and a front chassis.
    The rear frame comprises a first frame, called the rear frame 1010, and the front frame comprises a second frame, called the front frame 1011.
    As illustrated, the rear 1010 and front 1011 frames each have a substantially "U" shape whose dimensions, in particular the length, are substantially identical.
    The rear frames 1010 and front 1011 are articulated relative to each other so as to allow the folding of the trailer 100 (while minimizing its size during storage), and conversely its unfolding.
    The right and left ends 1010A of the rear frame 1010 are connected to the right and left ends 1011A of the front frame 1011 by means of connection means 102.
    The connecting means 102, located on each side of the trailer 100, comprise a pivot axis 1021 of the rear frame 1010 relative to the front frame 1011 (and therefore of the rear frame relative to the front frame).
    The pivot axes 1021 are coaxial.
    Furthermore, the trailer comprises a plate fixed to the chassis 101.
    Such a plate comprises a first portion, called the rear plate 1060, secured to the rear frame 1010 and a second portion, called the front plate 1061, secured to the front frame.
    1011.
    The rear plate 1060 and the front plate 1061 are coplanar, the space between these two plates being closed by a connection plate 1062 extending between the connection means 102 located on each side of the trailer, at the wheels of this last.
    The plate 1062 which is mounted on the front chassis is located in the space formed between the front 1161 and rear 1060 panels so as to be substantially coplanar therewith.
    In an implementation variant, no connecting plate is implemented, the edges of the rear plate 1060 and of the front plate 1061 being disposed facing each other (a predetermined space is provided between the two opposite edges ).
    The longitudinal ends of the plate 1062 are integral with the connecting means 102 located on each side of the trailer 100.
    The trailer 100 also comprises a drawbar 1012, a first end of which is secured to the front chassis and the second end of which is secured to a drawbar 103 allowing the trailer 100 to be fixed to a towing vehicle.
    A front wheel 104 is mounted on the drawbar 1012 by means of an adjustment mechanism 105 making it possible to adjust the height of the front wheel 104, and therefore the inclination of the trailer 100, so as to simplify the mounting of the hitch 103 on a towing vehicle.
    Furthermore, the trailer 100 advantageously implements a standard axle 107 sold commercially (FIG. 5B).
    Axle 107 includes an outer tube 107A of square section and an inner tube 107B of square section, forming a connecting tube, articulated at each of its ends to the mechanical arms 109 and wheel support hubs 108 (FIG. 5A) .
    The axle 107 is pivotally mounted relative to the wheels 108 of the trailer 100.
    Each of the mechanical arms 109 can rotate relative to the center of a wheel 108 clockwise F 2 , and counterclockwise F lt so as to tilt the trailer 100 from a low position, as illustrated in the figure. IB, at a high position, as illustrated in FIG. IA, and vice versa.
    The trailer 100 further comprises actuating means 110 making it possible to control the rotation of the mechanical arms 109 and therefore the movement of the trailer 100 between a first position, called the high position, and a second position, called the low position, and vice versa.
    Advantageously, the trailer 100 comprises locking means 111 for tilting the latter, distinct from the actuation means 110.
    These locking means 111 make it possible to block the rotation of the mechanical arms 109 when the trailer 100 is in the high position so as to avoid inadvertent passage of the trailer 100 in the low position.
    Thus, when the trailer 100 is in the high position, as shown in FIG. IA, the chassis 101 is substantially parallel to the ground.
    When a user wishes to load objects onto the tray 1060, 1061, the user disengages the locking means 111, then acts on the actuating means 110 so as to cause the mechanical arms 109 to pivot, according to an arc of a circle oriented in the direction of arrow F lt which causes rotation and lowering of the axle 107 and therefore of the chassis 101 of the trailer 100 mounted thereon.
    Thus, the user can easily load bulky objects on the tray 1060, 1061, because the slope of inclination of the frame 101 relative to the ground is relatively small (of the order of a few degrees).
    Once the object or objects have been loaded onto the tray, the user can actuate the actuating means 110 so as to cause the mechanical arms 109 and the axle 107 to pivot, according to an arc of a circle oriented in the direction of the arrow F 2 .
    Such pivoting has the effect of straightening the axle 107, and therefore the chassis 101 mounted thereon, until the chassis 101 is again substantially parallel to the ground.
    When the trailer is in the high position, the user reengages the locking means 111 so as to prevent the axle 107 from rotating.
    In the illustrated embodiment, a support S, making it possible to maintain an object, such as a motorcycle, when the latter is loaded on the trailer 100, is disposed on the front platform 1061.
    FIGS. 2 to 4 are top and bottom views of the trailer 100 of FIGS. 1A and 1B, which show the structure of the actuating means 110 for tilting the trailer and the locking means 111.
    In the embodiment illustrated in these figures, the actuating means 110 comprise a flexible element, which here is a strap, 1101 secured on the one hand to the axle 107 and on the other hand to a tensioner 1102, such a ratchet tensioner, which is integral with the chassis 101 (a hauling is thus carried out which makes it possible to easily raise the trailer).
    As illustrated, the ratchet tensioner 1102 is fixed to the front frame and includes two anchor points for the strap 1101.
    As can be seen in FIG. 3, the strap 1101 passes through a deflection piece 203 ′ secured to the axle 107, so that it extends in two parallel planes.
    The operation of such a ratchet tensioner 1102, well known to those skilled in the art, is not described here in detail. We understand that it allows to tension or release the tension force applied to the strap 1011, and therefore to play on the length of the latter.
    The locking means 111 comprise a sliding locking bar 1111 of which a first end 1111A is pivotally mounted on the axle 107, by means of a connecting piece 203, and a second end 1111B is mounted movable in translation, substantially along the longitudinal axis D of the trailer, inside a locking mechanism 1112 and a guide ring 1113 fixed to the chassis 101.
    This guide ring 1113 makes it possible to retain the locking bar 1111 in the low and storage positions of the trailer 100.
    The second end 1111B of the locking bar 1111 comprises a light 1114 (visible in FIGS. 4 and 6A) in which, in the high position of the trailer 100, a pin G is intended to be received.
    When the pin G is housed in the slot 1114, it cooperates with the locking mechanism 1112 and thus prevents any movement of the locking bar 1111, and therefore any rotation of the axle 107, when the trailer is in the high position.
    Furthermore, the rear chassis comprises a central spar 1013, and a cross-member 1014 making it possible in particular to strengthen the mechanical strength of the rear chassis.
    Similarly, the front chassis comprises a central beam 1015 and a cross member, 1016.
    The central spar 1015 carries the guide element 1113 and the drawbar 1012, the ratchet tensioner 1102 and the locking mechanism 1112 being integral with the front frame 1011.
    FIGS. 5A and 5B are detailed sectional views of the trailer 100, near a side wheel 108 of the latter, when the trailer is in the high position and in the low position respectively.
    These figures make it possible to detail the arrangement and the kinematics of the various elements of the trailer located near each side wheel 108.
    A mechanical arm 109 has a first end integral in rotation with a wheel 108 and a second end integral in rotation with the axle 107.
    Two articulation pieces 201, 202 fixed to each other by bolting around the outer tube 107A of the axle 107, make it possible to secure the axle 107 with the chassis of the trailer 100.
    More specifically, the articulation piece 202 is pivotally secured to the connecting means 102 in the space formed between the rear frames 1010 and before 1011.
    Furthermore, the strap 1101 of the control means is connected to the axle 107 by means of a deflection piece 203 ′ and the locking bar (not visible) of the locking means 111 is connected to the axle 107 by through a connecting piece 203.
    It should be noted that the pivoting solution of the axle described here makes it possible to keep the conventional interior suspension used on most baggage trailers, using four rubber profiles 204 integrated between the two square tubes 107A, 107B forming the axle 107.
    The rubber profiles 204 thus form means for suspending the trailer 100.
    The trailer of the invention is thus advantageous in that it can implement a standard axle on the market.
    When the user wishes to tilt the trailer 100 from the high position to the low position to load objects onto the platform, the user disengages the locking means 111 by removing the pin G so as to allow the axle 107 to rotate. and chassis movement.
    The user then actuates the ratchet tensioner so as to lengthen the strap 1101.
    The extension of the strap 1101 makes it possible, under the action of gravity exerted on the trailer, to cause the rotation of the axle 107 in an arc of a circle oriented in the direction of the arrow Fj.
    The trailer then comes in the low position.
    Once the object or objects have been loaded onto the trailer 100, the user actuates the ratchet tensioner to reduce the length of the strap 1101 so as to pull on the axle 107.
    The tensile force applied to the axle 107 allows the latter to rotate in an arc oriented in the direction of the arrow F 2 .
    As illustrated in FIG. 5B, when the trailer 100 is in the low position, the axle 107 and the articulation parts 201, 202 are housed in a hollow space 1025 formed in the lower part of the connecting means 102 and located between the front frame 1011 and rear frame 1010 of the chassis (that is to say in the platform of the trailer), which makes it possible to align the front and rear chassis in the same inclined plane, and to minimize the slope of inclination of the chassis 107 relative to the ground.
    FIGS. 6A and 6B are side views, respectively in the high position and in the low position, of the trailer 100.
    These figures illustrate the arrangement and the kinematics of the locking means 111 of the tilting of the trailer 100, when the latter is in the high position.
    When the trailer 100 is in the high position (FIG. 6A), the locking mechanism 1112, secured to the front frame 1011 of the chassis, retains the locking bar 1111 by means of the pin G which is housed in the light 1114 formed on the front end 1111B of the locking bar 1111.
    In other words, the locking bar 1111 is fixed relative to the chassis, the immobilization of the locking bar 1111 making it impossible to rotate the axle 107 and lowering the trailer 100.
    Thus, the locking means 111 make it possible to improve the reliability of the trailer 100 by reducing the risks of an untimely tilting of the latter.
    When the user wishes to tilt the trailer 100 in the low position for loading objects onto the platform, the user removes the pin G from the locking mechanism 1112, which frees the locking bar 1111 in translation and allows the rotation of axle 107.
    The displacement of the axle 107, induced by the actuation means 110 comprising the tensioner 1102 and the strap 1101, causes the locking bar 1111 to slide and the front end 1111B to be extracted from the locking bar 1111 out of the locking mechanism 1112.
    Figure 7 is a view of the trailer in a folded position, called the storage position.
    To store the trailer in the position shown, it is necessary to fold up the rear platform and then lower the trailer.
    Thus, the user first folds the rear frame towards the front frame, so that the rear frames 1010 and front 1011 are arranged opposite one another.
    Such a folding of the rear chassis towards the front chassis is ensured by means of the pivot axes 1021 of the connecting means 102 disposed between the rear frames 1010 and the front 1011.
    The user then removes the pin G from the locking mechanism 1112 so as to allow the sliding of the locking bar 1111 and therefore the rotation of the axle 107.
    Then, the user actuates the tensioner 1102 to reduce the tensile force exerted on the strap 1101 so as to allow rotation of the axle 107 and bring the trailer to the low position (FIG. 1B in particular).
    The user then lifts the trailer 100 to the vertical position.
    In such a position, the wheels 108 are always in contact with the ground, which makes it possible to easily move the trailer, for storing the latter for example.
    A retractable stand 112 carried by the rear chassis, at the cross member 1014, keeps the trailer 100 vertically.
    The trailer 100 is thus in the compact storage position (FIG. 7).
    Furthermore, the drawbar 1012 being pivotally mounted on the beam 1015, it can be folded and folded so as to further reduce the size of the trailer 100, in the storage position in particular.
    In the illustrated embodiment, the actuation means 110 for tilting the trailer 100 are manual.
    However, these actuating means can be motorized.
    Furthermore, the pin can be replaced by any other element, such as a rivet for example, making it possible to secure the locking bar to the locking mechanism.
    In the embodiment illustrated in Figures IA to 7, the means for actuating the pivoting of the axle and the tilting of the trailer comprise a strap connected to a tensioner.
    In another embodiment illustrated in FIG. 8, the actuation means 210 of the pivoting of the axle 207 relative to the wheels 208 and of the tilting of the trailer 200 comprise a flexible cable 2101, forming a flexible element, connected to a cable winding winch 2102.
    These actuating means 210 make it possible, as described above, to vary the position of the chassis 201 relative to the ground.
    The flexible cable 2101 is secured to the axle 207 and the cable winding winch 2102 is fixed to the chassis 201.
    More specifically, the winch 2102 is fixed to the frame before 2011 of the chassis 201.
