[0001] DESCRIPTION

[0002] Effortless vehicle luggage loading system

[0003] OBJECT OF THE INVENTION

[0004] The present invention relates to a loading system configured to introduce and / or extract at least one load into the interior space of a vehicle's trunk. This system, based on its configuration, allows a user to effortlessly insert and / or extract any load.

[0005] Additionally, the present invention also relates to a vehicle comprising at least one charging system as mentioned.

[0006] Finally, the present invention is also directed to both a method for introducing at least one load into the trunk of a vehicle and a method for removing at least one load from the trunk of a vehicle. These methods allow, through a series of steps, the user to effortlessly insert and remove any load from the interior of a vehicle, particularly from the trunk of a vehicle.

[0007] BACKGROUND OF THE INVENTION

[0008] In the technical field of vehicles and the spaces within said vehicles intended for cargo storage, trunks are predominantly located in the rear of the vehicle, with access to the storage space through a door or tailgate.

[0009] This technical field is constantly developing solutions that increase the useful trunk space for storing cargo, or that facilitate user access to the trunk space, with automated or remote access, as well as door openings that save the user effort when opening or closing the trunk.

[0010] However, once the storage space is accessible, users must make a great effort to introduce the loads into the vehicle's trunk, which often entails a high risk of injury to the user due to the weight of said loads or even the impossibility of introducing and / or removing the loads from the vehicle's trunk due to their heavy weight and the movements required by the user to perform such maneuvers, for example when the user is a small person or when the user has an injury or pathology in the legs, back or arms.

[0011] To avoid this problem, the current field of technology has only proposed solutions for freight transport vehicles, such as trucks, incorporating foldable surfaces that facilitate the entry and exit of loads, and for public passenger transport vehicles, such as buses, incorporating platforms, for example foldable ones, intended primarily for access by people with mobility difficulties, but not for access to other types of loads. Likewise, in public passenger transport vehicles, the state of the art also includes conveyor belts that facilitate the introduction of loads into the interior of the vehicle, particularly into the interior of the vehicle's trunk, thus allowing said loads to be positioned along the space provided for containing said loads, thus allowing for the organization of said space.

[0012] These systems effectively reduce the effort required by users and / or workers when loading and unloading loads from a vehicle's trunk.

[0013] However, in passenger vehicles it is not feasible to install and / or attach surfaces of this type due to the space they occupy and the weight they would imply for the movement of the vehicle, which would reduce the useful space of said vehicle for the user, and would considerably increase the vehicle's consumption due to the transport of these additional surfaces.

[0014] Thus, existing measures allow, in very specific cases, to reduce the effort required by users when loading and / or unloading a heavy load inside a vehicle, but they do not completely prevent it or allow for the reduction of this effort in any vehicle or for any user.

[0015] DESCRIPTION OF THE INVENTION

[0016] The present invention allows the aforementioned problems to be solved by means of a loading system that, through the configuration of its elements, allows the introduction and / or extraction of at least one load into the interior space of the trunk of a vehicle, intended to accommodate said at least one load.

[0017] This document also describes a vehicle that, through the aforementioned loading system, provides a solution for loading and unloading items inside a vehicle.

[0018] Finally, the present invention is also directed to a method of introducing at least one load into a trunk and to a method of extracting at least one load from the interior of a trunk by a user, from both a loading system and a vehicle such as those mentioned.

[0019] A first inventive aspect is therefore a loading system, configured to introduce and / or extract at least one load into the interior space of the trunk of a vehicle, wherein the interior space of the trunk comprises a first surface, a second surface and a third surface, wherein said first surface is essentially perpendicular to the second surface and to the third surface, wherein the interior space of the trunk comprises a fourth surface, essentially perpendicular to the second and third surfaces, wherein said trunk comprises a door configured to allow access to the interior space of the trunk in a first position of said door, wherein the door comprises a first face and a second face, opposite the first face and configured to delimit the interior space of said trunk in a second position of the door, wherein the second face,in said second position of the door it is essentially perpendicular to the second and third surfaces of the trunk, and characterized in that the loading system comprises: at least first displacement means, configured to move the load along a longitudinal direction Z-Z', wherein the first displacement means are located on the second face of the door of the trunk of the vehicle, at least second displacement means, configured to move the load on a plane configured by a first transverse direction X-X' and a second transverse direction Y-Y', said first transverse direction X-X' and second transverse direction Y-Y' being transverse to each other and transverse to the longitudinal direction Z-Z', wherein the at least second displacement means are located on at least one of the first, second, third and / or fourth surfaces of the interior space of the trunk of the vehicle,at least a first cable with a first end and a second end, wherein the first end is coupled to the at least first displacement means, and wherein the second end comprises first gripping means, at least a second cable with a first end and a second end, wherein the first end is coupled to the at least second displacement means, and wherein the second end comprises second gripping means, wherein the first gripping means are configured to couple to at least a first gripping point of the load, and wherein the second gripping means are configured to couple to at least a second gripping point of the load.,

[0020] Thus, the present loading system is configured in such a way that it eliminates the efforts made by a user in any manoeuvre of insertion and / or extraction of any load in / from the interior of the trunk of a vehicle, thus avoiding said user exerting forces and / or movements that cause injuries and / or discomfort to said user, and even avoiding the possibility that said user is not able, due to the size of the load or the magnitude of the effort or movement required, to carry out the corresponding manoeuvre.

[0021] In the context of the present invention, a vehicle is any automobile intended for the transportation of both people and cargo, according to the configuration of any vehicle, and is applicable to any vehicle requiring the introduction and removal of cargo from its interior. In particular, said vehicle comprises an interior space, specifically the interior space defined as the trunk, intended for the storage of cargo, said cargo being any package or item such as a suitcase, a box, or a bag. Likewise, the interior space of the trunk is accessible through a door, which allows both completely delimiting said interior space and allowing access from outside the vehicle to said interior space of the trunk. In a particular embodiment, the vehicle is a passenger car.

[0022] In a particular embodiment, the trunk is located at the rear of the vehicle, that is, at the rear of the space intended for user accommodation, according to the usual direction of travel of the vehicle (forward, along the longitudinal direction X-X').

[0023] Thus, the trunk comprises a useful interior space, configured to accommodate loads, defined by a plurality of surfaces that delimit said interior space. In a particular embodiment, the interior space of the trunk is configured as an essentially rectangular parallelepiped.

[0024] In particular, the interior space of the vehicle's trunk comprises a first surface, which is essentially perpendicular to a second and a third surface. Likewise, the interior space of the trunk also comprises a fourth surface, which is essentially perpendicular to the second and third surfaces.

[0025] In a particular embodiment, the fourth surface is also essentially perpendicular to the first surface.

[0026] In a particular embodiment, the first surface corresponds to the front surface of the interior space of the trunk, that is, to the surface located at the rear of the rear seats of the vehicle, while the second surface and the third surface correspond to the sides of the interior space of the trunk, corresponding in turn to the sides of the vehicle, and the fourth surface corresponds to the base or floor of the interior space of the trunk of the vehicle.

[0027] On the other hand, the trunk of the vehicle also comprises a door, which in turn comprises a first side, located on the outside of the vehicle, and a second side, opposite said first side.

[0028] Likewise, the trunk door that allows access to its interior space is configured to adopt: a first position, or open position, where the first, second, third and fourth surfaces are accessible from the outside of the vehicle, and it is possible to introduce and / or extract a load from the interior space of the trunk, thus leaving the second face of the door away from the interior space of the trunk, and a second position, or closed position, where the interior space of the trunk is completely delimited by the first, second, third and fourth surfaces together with the second face of the door, said second face being essentially perpendicular to the second and third surfaces, such that the interior space of the trunk is not accessible from the outside and it is not possible to introduce and / or extract a load from said interior space of the trunk.

[0029] In a particular embodiment, the second face of the door, in the second position of said door, faces the first surface of the interior space of the trunk.

[0030] In a particular embodiment, the second face of the door, in the second position of said door, is perpendicular to the fourth surface.

[0031] In this way, the loading system according to the first inventive aspect is configured to introduce and / or extract any load from / to the outside of the vehicle to / from the interior space of the trunk of the vehicle.

[0032] To this end, the loading system comprises at least first movement means located on the second side of the trunk door, such that, in the first position of the door, the at least first movement means are exposed to the outside of the vehicle, and in the second position of the door, the at least first movement means are housed in the interior space of the trunk of the vehicle.

[0033] Said at least first moving means are configured to move the at least one load along a longitudinal direction Z-Z', in particular in the first position of the door.

[0034] In a particular embodiment, the longitudinal direction Z-Z' is the vertical direction.

[0035] Advantageously, these first movement means allow the load to be moved longitudinally without the user having to strain to hold it. In a particular embodiment, the at least first movement means allow the load to be raised vertically, either to raise said load from the floor outside the vehicle to the interior space of the trunk, or to lower said load from the interior space of the trunk to the floor outside the vehicle.

[0036] In a particular embodiment, the at least first displacement means further comprise extension means, configured to move the position of the first displacement means along the first transverse direction X-X'.

[0037] This advantageously allows the position of the at least one first movement means to be adjusted, increasing the load's maneuverability and increasing the positioning accuracy of the loading system relative to the at least one load to be handled. Likewise, adjusting the position of the at least one first movement means also allows the load to be kept sufficiently far from the vehicle parts outside the trunk, such that during positioning the load, it does not rub or collide with said exterior parts of the vehicle.

[0038] The loading system also comprises at least second moving means, located on at least one of the first, second, third and / or fourth surfaces of the interior space of the trunk.

[0039] Said second moving means are configured to move the load on a plane configured by a first transverse direction X-X' and a second transverse direction Y-Y', said first transverse direction X-X' and second transverse direction Y-Y' being transverse to each other and transverse to the longitudinal direction Z-Z', in particular in the first position of the door.

[0040] In a particular embodiment, the first transverse direction XX and the second transverse direction Y-Y' correspond to two horizontal directions, perpendicular to the vertical direction Z-Z', thus forming said first transverse direction X-X' and second transverse direction Y-Y' a horizontal plane.

[0041] Advantageously, the at least second movement means allow, in combination with the at least first movement means, to move the load longitudinally without the user making the effort to hold it, allowing in turn greater mobility of the load and, therefore, greater maneuverability to introduce and / or extract it in / from the interior space of the trunk.

[0042] In a particular embodiment, the loading system comprises second movement means, coupled either to the first surface or to the fourth surface of the vehicle's trunk. This advantageously allows for the implementation of a single anchoring point for the second movement means, with the fourth surface being the most robust because it belongs to, is adjacent to, or is close to the vehicle's chassis.

[0043] In a particular embodiment, the second movement means are coupled at a midpoint of the first surface or the fourth surface of the vehicle's trunk, which advantageously allows a centered and symmetrical position of said second movement means, and better maneuverability of the load.

[0044] In a particular embodiment, the second movement means are coupled at the intersection of the first and fourth surfaces of the vehicle's trunk, which advantageously allows for a more robust anchoring of said second movement means.

[0045] In a particular embodiment, the loading system comprises two second displacement means, each coupled respectively to the second surface and the third surface of the vehicle's trunk. In a particular embodiment, each of the two second displacement means is coupled to a point adjacent to the second surface and / or to a point adjacent to the third surface of the vehicle's trunk.

[0046] Advantageously, this allows for a symmetrical arrangement of the loading system, allowing for better distribution and anchoring of at least one load.

[0047] The loading system further comprises at least a first cable with a first end and a second end, wherein the first end is coupled to the at least first movement means, and wherein the second end comprises first gripping means, configured to couple to at least a first gripping point of the load.

[0048] Likewise, the loading system also comprises at least a second cable with a first end and a second end, wherein the first end is coupled to the at least second movement means, and wherein the second end comprises second gripping means, configured to couple to at least a second gripping point of the load.

[0049] Advantageously, the at least one first cable and the at least one second cable allow the guided movement of the load, necessary for its introduction / extraction from the interior space of the trunk.

[0050] Likewise, the first and second gripping means advantageously allow the load to be secured to the loading system via its gripping points, and therefore the load to be held during any maneuver or inside the vehicle, thereby ensuring the correct position of said load.

[0051] In a particular embodiment, the loading system comprises a second cable coupled to each of the second movement means, wherein each of said second cables comprises second gripping means configured to be coupled respectively to a second gripping point of the load, said second gripping points facing each other.

[0052] This advantageously allows for a homogeneous and symmetrical load distribution, which improves any maneuver performed by the loading system.

[0053] In a particular embodiment, the at least one first grip point and the at least one second grip point and / or the second grip points of the load are coincident.

[0054] In a particular embodiment, the at least one first gripping point and the at least one second gripping point of the load are contiguous, which advantageously allows the anchoring of the first movement means and the second movement means, respectively, to be facilitated by being carried out at points close to the surface of the load, while the position of the load during its movement remains stable. In a particular embodiment, the at least one first gripping point is located on the upper surface of the load, and the at least one second gripping point is located on a lateral surface of the load, adjacent to the upper surface of the load.

[0055] In a particular embodiment, the load comprises at least one wheel configured to allow the load to slide, both on the outside and inside the trunk, preferably on the fourth surface of the trunk. In a particular embodiment, the at least one wheel is located on the surface opposite the surface comprising the first load attachment point. In a particular embodiment, the at least one wheel is located on the surface of the load that, in an operational situation, that is, once it has been placed in the trunk of the vehicle, is in contact with the fourth surface thereof.

[0056] In a particular embodiment, the load is a suitcase, thus corresponding the at least one first point of gripping the load either with at least one top handle of the suitcase or with at least one side handle of the suitcase, and the at least one second point of gripping the load either with at least one of the side handles of the suitcase or with the top handle of the suitcase, respectively.

[0057] In a particular embodiment, the load is a tank, that is, any element that can accommodate elements inside it, such as a container, a box or a covered structure, which comprises at least a first grip point and at least a second grip point.

[0058] Advantageously, this allows the load to be grouped inside a robust element, configured to support said load and to be manipulated by the loading system according to the first inventive aspect.

[0059] In a particular embodiment, the tank comprises means for securing at least one of the elements housed in said tank. This advantageously prevents the elements from moving inside the tank, thereby preventing the load from shifting or falling.

[0060] In a particular embodiment, the interior space of the trunk also comprises guide means configured to guide the movement of the load. Advantageously, this allows the load to move at a fixed rate within the interior space of the trunk and, therefore, remain optimally positioned within said interior space.

[0061] In a particular embodiment, the guiding means are located on the fourth surface of the interior space of the trunk.

[0062] In a particular embodiment, the guiding means comprise articulated and / or sliding bars.

[0063] In a particular embodiment, the first movement means and / or the second movement means are winches, which allow the winding of the first and / or second cable in a corresponding manner, as well as the securing of the load through said first and / or second cable through the winch(s).

[0064] In a particular embodiment, the first means of movement and / or the second means of movement comprise distribution means, located on the first surface and / or on the second surface and / or on the third surface and / or on the fourth surface of the trunk of the vehicle and / or on the second face of the trunk door, said distribution means being configured to cooperate with the movement of the at least one load.

[0065] In a particular embodiment, the loading system comprises second movement means located on the fourth surface of the trunk, and said second movement means comprise distribution means located on the second and third surfaces of the trunk.

[0066] In a particular embodiment, the distribution means of the at least first displacement means and / or the at least second displacement means are at least one pulley.

[0067] In a particular embodiment, the second movement means comprise winches located on the fourth surface of the trunk. Likewise, the distribution means of said second movement means are at least one pulley located on the second surface of the trunk and at least one pulley located on the third surface of the trunk. Advantageously, the distribution means, particularly the pulleys, allow for the configuration of a mechanism that reduces the effort required for the user to move the at least one load using said loading system.

[0068] In a particular embodiment, the configuration of the first displacement means and the second displacement means is symmetrical with respect to the plane formed by the longitudinal direction Z-Z' and the first transverse direction X-X', that is, with respect to the plane ZX.

[0069] In a particular embodiment, the charging system comprises a third cable, configured to connect at least two distribution means of the first and / or second displacement means.

[0070] In a particular embodiment, the third cable is configured to connect at least one distribution means of the first displacement means and at least one distribution means of the second displacement means.

[0071] In a particular embodiment, the first movement means comprise two winches and two pulleys, configured to be fixed to the second surface of the trunk door. Likewise, the second movement means comprise two winches, configured to be fixed to the fourth surface of the trunk, as well as two distribution means, specifically two pulleys, fixed either to the second and third surfaces, or to the fourth surface of the trunk. In this way, each pulley is mechanically connected to one of the winches.

[0072] In a particular embodiment, the first movement means comprise two winches and four distribution means, specifically four pulleys, two of which are configured to be fixed to the second and / or third and / or fourth surfaces of the trunk and two of which are configured to be fixed to the second side of the trunk door. Likewise, the second movement means comprise two winches, configured to be fixed to the fourth surface of the trunk, as well as two distribution means, specifically two pulleys, fixed to the second and third surfaces or to the fourth surface of the trunk. In this way, each pulley is mechanically connected to one of the winches. In a particular embodiment, the first movement means and / or the second movement means are electric, which advantageously allows the user to not exert any physical effort in handling them.

[0073] In a particular embodiment, said first and / or second electric displacement means are configured to be manipulated either by means of actuation means located in the vehicle, or remotely.

[0074] In a particular embodiment, the loading system further comprises support means, which in turn comprise: a first support, coupled to the second face of the trunk door of the vehicle, comprising a first end and a second end, two second supports, coupled either to the fourth surface, or to the second surface and the third surface respectively, or respectively to the intersection between the fourth and the second surface and the third surface of the trunk of the vehicle, and to the first end and second end of the first support, and two third supports, coupled respectively to the first end and second end of the first support wherein the coupling between each third support and the first and second end of the first support is an articulated coupling, and wherein, in the first position of the trunk door of the vehicle, the third supports extend along the longitudinal direction Z-Z'.

[0075] Advantageously, the support means allow for greater stability of the loading system, as well as the possibility of handling larger and / or heavier loads using a more rigid and robust auxiliary structure, thus protecting the trunk lid from possible deformations caused by a heavy load.

[0076] These support means, based on their configuration, allow for optimal stress distribution, which minimizes any effort exerted by the user in relation to load handling, as well as protecting the system from potential configuration failures due to the heavy weight or volume of the load. In a particular embodiment, the first support is configured to be coupled and / or decoupled from the second side of the vehicle's trunk lid.

[0077] In a particular embodiment, the first movement means are coupled to the first support and / or the second movement means are coupled to at least one of the second supports, such that the support means act as an intermediate structure between the trunk and the elements of the loading system, allowing for optimal distribution of stresses in the loading system.

[0078] In a particular embodiment, at least one of the third supports also comprises support means, which provides greater stability to the support means and, therefore, to the loading system.

[0079] In a particular embodiment, said support means are a base for the third supports, said base comprising an upper surface that allows a more stable support of the support means on a surface outside the trunk of the vehicle, for example, the floor outside the vehicle.

[0080] In a particular embodiment, the second supports and / or the third supports comprise telescopic means, configured to regulate the length of each second support and / or third support respectively.

[0081] This advantageously allows the regulation of the position of the support means in relation to the outside of the vehicle trunk, as well as in relation to the at least one load, thus allowing greater precision in the movement of said at least one load.

[0082] In a particular embodiment, the loading system further comprises at least one sensor configured to detect a load and / or a first gripping point and / or a second gripping point. That is, the at least one sensor is configured to detect a load that must be moved.

[0083] In a particular embodiment, the loading system further comprises means for controlling the first movement means and / or the second movement means and / or the second supports of the support means and / or the third supports of the support means. Said control means advantageously allow the manipulation of the different elements of the loading system by the user, that is, the manipulation of the first movement means and / or the second movement means and / or the second supports of the support means and / or the third supports of the support means and / or the first gripping means and / or the second gripping means and / or the at least one sensor and / or the extension means.

[0084] In a particular embodiment, the control means allow electrical manipulation of the aforementioned charging system components, which in turn allows the user to not make any physical effort in handling them.

[0085] In a particular embodiment, the control means allow electrical manipulation of the extension means.

[0086] In a second inventive aspect, the present invention defines a vehicle comprising a charging system according to the first inventive aspect.

[0087] Advantageously, the location of a loading system as defined in the first inventive aspect in a vehicle allows the manipulation of a load by a user without the need for physical effort.

[0088] In a third inventive aspect, the present invention defines a method for introducing at least one load, comprising at least one first gripping point and at least one second gripping point, into the interior space of the trunk of a vehicle comprising a loading system according to the first inventive aspect, characterized in that the method comprises the following steps: a) coupling, with the trunk door of the vehicle in the first position, the first gripping means of the at least one first cable to the at least one first gripping point of the load, b) moving the load along the longitudinal direction Z-Z' towards the at least one first moving means by winding the at least one first cable around said at least one first moving means,c) moving the load on the plane configured by the first transverse direction X-X' and the second transverse direction Y -Y' towards the at least second moving means by winding the at least one second cable around said at least one second moving means and, simultaneously, by unwinding the at least one first cable around said at least one first moving means, d) positioning the load in the interior space of the trunk, and e) decoupling the first gripping means of the at least one first cable from the at least one first gripping point of the load.

[0089] In this way, the present introduction method advantageously allows a user to introduce at least one load into the interior of the vehicle's trunk without effort, thus allowing any user to introduce a load into the interior of the vehicle despite the volume or high weight of said load.

[0090] First, the present method requires a user to attach, via the first gripping means, the at least one first cable of the charging system to the load to be introduced into the trunk of the vehicle.

[0091] In this way, step a) of the present introduction method requires positioning the load with respect to the at least first movement means and fixing said load to the loading system through the at least one first cable, thus allowing the movement of the load along the longitudinal direction Z-Z'.

[0092] In a particular embodiment, the at least one first grip point and the at least one second grip point are coincident.

[0093] The present method then requires the user to activate the at least first movement means, such that the load is moved along the longitudinal direction Z-Z' toward said at least first movement means. Said movement of the load is carried out by winding the at least one first cable around the at least first movement means, which allows said movement to be progressive and adjustable by the user.

[0094] In a particular embodiment, step b) involves lifting the load until it reaches at least the first moving means, for subsequent insertion into the trunk. Advantageously, this allows the load to be moved, or lifted, by the loading system, avoiding the user having to bear the weight of said load.

[0095] In a particular embodiment, either step a) or step b) comprises the action of coupling the second gripping means of the at least one second cable to the at least one second gripping point of the load, which allows the load to be positioned with respect to the at least one second movement means and, therefore, allows the movement of the load also according to the plane configured by the first transverse direction X-X' and the second transverse direction Y-Y' by the loading system.

[0096] Advantageously, this allows the user to secure the load to the loading system via the at least one second cable either when the load is resting on the outer surface of the trunk, or when the load is displaced along the longitudinal direction Z-Z', and therefore in a higher position than the position in which it is resting on the outer surface of the trunk, which makes it possible to avoid additional movements and stresses for the user.

[0097] Additionally, the present method requires the user to activate the at least second movement means, such that the load is moved along the first transverse direction X-X' and the second transverse direction Y-Y', and therefore on the planes formed by said directions and the longitudinal direction Z-Z', towards the at least second movement means. Said movement of the load is carried out by winding the at least one second cable over the at least second movement means, which allows said movement to be progressive and adjustable by the user. Likewise, said movement also requires the unwinding of the at least one first cable over the at least first movement means.

[0098] In a particular embodiment, step c) involves moving the load until it reaches and / or is located in a position close to at least a second moving means, for the complete introduction of the load into the trunk.

[0099] Advantageously, this allows the cargo system to move or drag the load, avoiding the user having to strain to bear the weight of the load. Subsequently, the loading method requires positioning the load in the interior space of the trunk, so that it rests on the fourth surface of the trunk.

[0100] Finally, the introduction method requires decoupling the first gripping means of the at least one first cable from the first gripping point of the load, such that the at least one first cable is collected on the at least one first movement means, and the load is positioned inside the trunk.

[0101] In a particular embodiment, the introduction method further comprises step f) of decoupling the second gripping means of the at least one second cable from the at least one second gripping point of the load.

[0102] Advantageously, this allows the loading system to be re-equipped for loading additional cargo into the trunk, while the cargo already loaded has been placed in its optimal position.

[0103] In a particular embodiment, the introduction method comprises a step prior to step a), in the case of a loading system comprising support means, this additional step being the following: a.0) aligning, according to the longitudinal direction Z-Z', the third supports by means of rotation, through the articulated coupling, of said third supports with respect to the first and second end of the first support.

[0104] In a particular embodiment, in step a.0) the support means are also positioned on a surface outside the vehicle, where the load to be introduced into the vehicle is supported.

[0105] That is, the method of introduction requires, beforehand, positioning the support means on the outside of the vehicle's trunk, so that their position relative to the load is adequate to begin the maneuver of introducing said load into the interior of the vehicle's trunk.

[0106] Advantageously, the combination of steps in this method of introduction allows a user to introduce at least one load into the trunk of a vehicle without any effort.

[0107] In a particular embodiment, said conjunction of stages is carried out, at least partially, automatically through first displacement means and / or at least second electrical displacement means.

[0108] In a particular embodiment, steps a) and / or e) and / or f) are performed, at least partially, automatically through first gripping means and / or second electric gripping means.

[0109] In a particular embodiment, where the loading system comprises at least one sensor and control means, at least one of steps a) and / or b) and / oc) and / od) and / or e) and / or f) and / or aO) are carried out automatically by the at least one sensor and the control means. That is, the at least one sensor allows a load and / or any gripping point of said load to be detected, while the control means allow the loading system to be manipulated remotely and / or automatically to introduce the detected load into the interior space of the trunk.

[0110] Advantageously, this allows for the automated loading of cargo into the trunk space, eliminating any effort on the part of the user.

[0111] In a fourth inventive aspect, the present invention defines a method for extracting at least one load, comprising at least a first gripping point and at least a second gripping point, from the interior space of the trunk of a vehicle comprising a loading system according to the first inventive aspect, characterized in that the method comprises the following steps: a) coupling, with the trunk door of the vehicle in the first position, the first gripping means of the at least one first cable to the at least one first gripping point of the load, b) moving on the plane configured by the first transverse direction X-X' and the second transverse direction Y-Y' towards the outside of the interior space of the trunk by unwinding the at least one second cable around the at least one second movement means and, simultaneously, by winding the at least one first cable around the at least one first movement means,c) moving the load along the longitudinal direction Z-Z' by unwinding the at least one first cable around said at least one first moving means until the load is positioned on a surface outside the vehicle where it is supported, and, d) uncoupling the first gripping means of the at least one first cable from the at least one first gripping point of the load.

[0112] In this way, the present extraction method advantageously allows a user to extract at least one load from the interior of the vehicle's trunk without effort, thus allowing any user to extract a load from the interior of the vehicle despite the volume or high weight of said load.

[0113] First, the present method requires a user to attach, via the first gripping means, the at least one first cable of the charging system to the load to be removed from the interior of the trunk of the vehicle.

[0114] In this way, step a) of the present extraction method requires fixing said load to the loading system through at least a first cable, thus allowing the displacement of the load along the longitudinal direction Z-Z' by the loading system.

[0115] In a particular embodiment, the extraction method further comprises, simultaneously with the execution of step a), the action of coupling the second gripping means of the at least one second cable to the at least one second gripping point of the load, which allows a user to fix, through the second gripping means, the at least one second cable of the loading system to the load that is to be extracted from the inside of the trunk of the vehicle.

[0116] In a particular embodiment, the at least one first grip point and the at least one second grip point are coincident.

[0117] The present method then requires the user to activate the at least second movement means, such that the load is moved along the first transverse direction X-X' and the second transverse direction Y-Y', and therefore on the planes formed by said directions and the longitudinal direction Z-Z', moving away from the at least second movement means. Said movement of the load is carried out by unwinding the at least one second cable over the at least second movement means, which allows said movement to be progressive and adjustable by the user. Likewise, said movement also requires winding the at least one first cable over the at least first movement means, bringing the load closer to said at least first movement means.

[0118] In a particular embodiment, step b) involves moving the load until it reaches the position furthest from the at least second moving means, for the complete extraction of the load from the interior of the trunk.

[0119] Advantageously, this allows the load to be moved or dragged by the loading system, avoiding the user having to bear the weight of said load.

[0120] Additionally, the present method requires the user to activate the at least first movement means, such that the load moves in the longitudinal direction Z-Z', moving away from said at least first movement means towards a surface outside the vehicle where said load is supported. Said movement of the load is carried out by unwinding the at least one first cable over the at least first movement means, which allows said movement to be progressive and adjustable by the user.

[0121] In a particular embodiment, step c) involves lowering the load until it reaches the position furthest from the at least first moving means, positioning itself on the surface outside the vehicle, thus completely removing the load from inside the trunk.

[0122] Advantageously, this allows the load to be moved or lowered by the loading system, avoiding the user having to bear the weight of the load.

[0123] Finally, the extraction method requires decoupling the first gripping means of the at least one first cable from the at least one first gripping point, such that the at least one first cable is collected on the at least one first movement means, while the load is positioned outside the trunk and at least partially released from the loading system.

[0124] In a particular embodiment, either step b) or step d) comprises the action of decoupling the second gripping means of the at least one second cable from the at least one second gripping point of the load, which allows the at least one second cable to be collected on the at least one second movement means, as well as completely releasing the load from the loading system.

[0125] Advantageously, this allows the user to release the load from the loading system via the at least one second cable either when the load is already resting on the outer surface of the trunk, or when the load is displaced along the longitudinal direction Z-Z', and therefore in a higher position than the position in which it is resting on the outer surface of the trunk, which makes it possible to avoid additional movements and stresses for the user.

[0126] In a particular embodiment, the extraction method comprises a step prior to step a), in the case of a loading system comprising support means, this additional step being the following: a.0) aligning, according to the longitudinal direction Z-Z', the third supports by means of rotation, through the articulated coupling, of said third supports with respect to the first and second end of the first support.

[0127] In a particular embodiment, in step a.0) the support means are also positioned on the surface outside the vehicle, where the load to be introduced into the vehicle is supported.

[0128] That is, the extraction method requires, beforehand, positioning the support means on the outside of the vehicle's trunk, so that their position relative to the load is adequate to begin the maneuver of introducing said load into the interior of the vehicle's trunk.

[0129] Advantageously, the combination of steps in the present extraction method allows a user to extract at least one load from the trunk of a vehicle without any effort. In a particular embodiment, said combination of steps is performed, at least partially, automatically by means of at least first moving means and / or at least second electric moving means.

[0130] In a particular embodiment, steps a) and / or d) are carried out, at least partially, automatically through first gripping means and / or second electric gripping means.

[0131] In a particular embodiment, where the loading system comprises at least one sensor and control means, at least one of steps a) and / or b) and / or c) and / or d) and / or aO) are carried out automatically by the at least one sensor and the control means. That is, the at least one sensor allows a load and / or any attachment point of said load to be detected, while the control means allow the loading system to be manipulated remotely and / or automatically to extract the detected load from the interior space of the trunk.

[0132] Advantageously, this allows for automated removal of a load from the interior trunk space, avoiding any effort on the part of the user.

[0138] PREFERRED EMBODIMENT OF THE INVENTION

[0139] Figures 1A - 1D show the same profile view of a first particular embodiment of a vehicle (2) according to the second inventive aspect. Figures 1A - 1D also show a sequence of steps in the methods for introducing and extracting a load into / from the interior of the trunk of said vehicle, in particular, Figures 1A - 1D in this order show a sequence of steps in the method for introducing a load into the interior of the trunk of the vehicle (2), while the same Figures 1A - 1D in reverse order, that is, Figures 1D - 1A, show the steps in the method for extracting a load from the interior of the trunk of the vehicle (2).

[0140] In particular, Figure 1A shows a vehicle (2) extending longitudinally along the first transverse direction X-X', or horizontal direction according to the orientation of the present figure, and in height along the longitudinal direction Z-Z', or vertical direction according to the orientation of Figure 1A.

[0141] Said vehicle (2) comprises a trunk (2.1) with an interior space (2.1.1) and a door (2.1.2) which, in a first position, or open position, extends mainly along the first X-X' and second Y-Y' (not shown) transverse directions, that is, it extends horizontally along the plane formed by said first X-X' and second Y-Y' transverse directions, and in a second position, or closed position, it extends mainly along the longitudinal direction Z-Z' and the second transverse direction Y-Y', that is, vertically along the plane formed by said second transverse direction Y-Y' and said longitudinal direction Z-Z'.

[0142] The door (2.1.2) in turn comprises a first face (2.1.2.1), located on the outside of the vehicle (2) both in the open position and in the closed position of the door (2.1.2), and a second face (2.1.2.2) located on the inside of the vehicle (2) when the door is in the second position (closed position).

[0143] Likewise, the interior space (2.1.1) forms a parallelepiped when the door (2.1.2) is in the second position (closed position), where any load can be accommodated (C).

[0144] The sides of said parallelepiped in the closed position of the door (2.1.2) are configured by a first surface (2.1.1.1), or rear surface of the rear seats, a second surface (2.1.1.2) and a third surface (2.1.1.3) or side surfaces, adjacent to the chassis of the vehicle (2), and the second face (2.1.2.2) of the door (2.1.2) such that the first surface (2.1.1.1) and the second face (2.1.2.2) of the door (2.1.2) face each other, as well as the second surface (2.1.1.2) and the third surface (2.1.1.3) face each other.

[0145] Figure 1A shows a first embodiment of a loading system (1) for positioning a load (C) inside the trunk (2.1), installed in a vehicle (2) with the indicated characteristics. In this way, the loading system (1) allows both the introduction and extraction of a suitcase (C), with a first upper grip point (C.1) and a second lateral grip point (C.2), in the interior space (2.1.1) of the trunk (2.1) of the vehicle (2).

[0146] As shown in this figure, the first upper grip point (C.1) is the upper handle (C.1) of the suitcase (C), and the second lateral grip point (C.2) is the lateral handle (C.2) of the suitcase (C).

[0147] The loading system (1) comprises first movement means (1.1), configured by means of a first winch (1.1), and a first cable (1.3) with a first end (1.3.1) and a second end (1.3.2).

[0148] As shown in figure 1A, the first end (1.3.1) is coupled to the first winch (1.1), while at the second end (1.3.2) there are first gripping means (1.3.3), for example, a clamp or carabiner, which are coupled to the upper handle (C.1) of the suitcase (C).

[0149] The first moving means (1.1), or first winch (1.1), is coupled and fixed to the second side (2.1.2.2) of the door (2.1.2).

[0150] Likewise, the first winch (1.1) comprises extension means (1.1.1) that also extend along the longitudinal direction X-X', that is, horizontally, so that they allow the first end (1.3.1) of the cable to be moved along said direction.

[0151] (1.3), and therefore the position of the first winch (1.1) with respect to the suitcase (C), so that during the movement of said suitcase (C) it is prevented from hitting any external part of the vehicle (2).

[0152] On the other hand, the loading system (1) also comprises second movement means (1.2), configured by means of a second winch (1.2), and a second cable (1.4) with a first end (1.4.1) and a second end (1.4.2).

[0153] As shown in figure 1A, the first end (1.4.1) of the second cable (1.4) is coupled to the second winch (1.2), while at the second end (1.4.2) of the second cable (1.4) there are second gripping means.

[0154] (1.4.3), for example, a clamp or carabiner, which are attached to the side handle (C.2) of the suitcase (C).

[0155] The second means of movement (1.2), or second winch (1.2), is coupled and fixed to a central point of the first surface (2.1.1.1) of the trunk (2.1).

[0156] Likewise, Figure 1A shows stage a) of the method of introducing a suitcase (C) into the interior space (2.1.1) of the trunk (2.1) of the vehicle (2), where the first

[0157] (1.3.3) and second (1.4.3) gripping means are coupled to the load (C), or suitcase (C), with the door (2.1.2) of the trunk (2.1) of the vehicle (2) open.

[0158] Additionally, Figure 1A also shows the position of the load (C), or suitcase (C), in which step d) of the method of extracting a suitcase (C) from the interior space (2.1.1) of the trunk (2.1) towards the outside of the vehicle (2) would be carried out.

[0159] Figure 1B shows the same vehicle (2) and the same loading system (1) as in Figure 1A.

[0160] Likewise, Figure 1B shows stage b) of the method for introducing a suitcase (C) into the interior space (2.1.1) of the trunk (2.1) of the vehicle (2), where the load (C), or suitcase (C), has been raised towards the first winch (1.1) collecting the corresponding length of the first cable (1.3) on said first winch (1.1) to finally tighten the second cable (1.4) when beginning to collect the corresponding length of the second cable (1.4) on the second winch (1.2).

[0161] In this way, the suitcase (C) is in the position closest to the first winch (1.1), with the loading system having lifted the suitcase (C) and its weight without any effort from the user.

[0162] Figure 1 B also shows the start of step c) of the method for extracting a suitcase (C), said suitcase (C) being positioned to move in a vertical direction, or Z-Z' direction, towards the exterior surface of the vehicle (2) on which it rests as shown in Figure 1A.

[0163] Figure 1C shows the same vehicle (2) and the same loading system (1) as in Figures 1 A and 1 B.

[0164] Likewise, Figure 1C shows stage c) of the method of introducing a suitcase (C) into the interior space (2.1.1) of the trunk (2.1) of the vehicle (2), where the load (C), or suitcase (C), has been tilted so that it is positioned to move towards the second winch (1.2).

[0165] Figure 1C also shows the position of the suitcase (C) in step b) of the method for extracting a suitcase (C), said suitcase (C) being positioned at an intermediate point in said step b).

[0166] Finally, Figure 1D shows the same vehicle (2) and the same loading system (1) as in Figures 1A - 1C.

[0167] Likewise, Figure 1 D shows step d) of the method for introducing a suitcase (C) into the interior space (2.1.1) of the trunk (2.1) of the vehicle (2), where the load (C), or suitcase (C), has been positioned on the fourth surface (2.1.1.4) of said interior space (2.1.1). Steps e) and f) of said method for introducing a suitcase (C) are not shown in the present figures.

[0168] As shown, the first cable (1.3) has been unwound onto the first winch (1.1), while the second cable (1.4) has been wound onto the second winch (1.2), so that the suitcase (C) is in the position closest to the second winch (1.2).

[0169] Figure 1 D also shows the suitcase (C) after performing step a) of the method for extracting a suitcase (C), said suitcase (C) being positioned inside the trunk (2.1) of the vehicle for its extraction towards the outside of the vehicle (2).

[0170] Figures 2A and 2B show an elevation view of a second particular embodiment of a vehicle (2) according to the second inventive aspect. Figures 2A and 2B also show some of the steps of the methods for introducing and extracting a load (C) into / from the interior of the trunk (2.1) of said vehicle (2).

[0171] Said vehicle (2) comprises a trunk (2.1) with an interior space (2.1.1) and a door (2.1.2) which, in a first position, or open position, extends mainly along the first X-X' (not shown) and second Y-Y' transverse directions, that is, it extends horizontally along the plane formed by said first X-X' and second Y-Y' transverse directions, and in a second position, or closed position, it extends mainly along the longitudinal direction Z-Z', that is, vertically along the plane formed by said second transverse direction Y-Y' and said longitudinal direction Z-Z'.

[0172] The door (2.1.2) in turn comprises a first face (2.1.2.1), located on the outside of the vehicle (2) both in the open position and in the closed position of said door.

[0173] (2.1.2), and a second face (2.1.2.2) located inside the vehicle (2) when the door (2.1.2) is in the second position (closed position).

[0174] Likewise, the interior space (2.1.1) forms a parallelepiped when the door (2.1.2) is in the second position (closed position), where any load (C) can be accommodated.

[0175] The sides of said parallelepiped in the closed position of the door (2.1.2) are configured by a first surface (2.1.1.1), or rear surface of the rear seats, a second surface (2.1.1.2) and a third surface (2.1.1.3) or side surfaces, adjacent to the chassis of the vehicle (2), and the second face (2.1.2.2) of the door (2.1.2.2), such that the first surface (2.1.1.1) and the second face

[0176] (2.1.2.2) of the door (2.1.2.2) face each other, just as the second surface (2.1.1.2) and the third surface (2.1.1.3) face each other.

[0177] In particular, Figure 2A shows a second embodiment of a loading system (1) for positioning a load (C) inside the trunk (2.1), installed in a vehicle (2) with the indicated characteristics. In this way, the loading system (1) allows both the introduction and extraction of a suitcase (C), with a first upper grip point (C.1) and two second lateral grip points (C.2), in the interior space (2.1.1) of the trunk (2.1) of the vehicle (2).

[0178] As shown in this figure, the first upper grip point (C.1) is the upper handle (C.1) of the suitcase (C), and the second lateral grip points (C.2) are the side handles (C.2) of the suitcase (C).

[0179] The loading system (1) comprises first movement means (1.1), configured by means of a first winch (1.1), and a first cable (1.3) with a first end (1.3.1) and a second end (1.3.2).

[0180] As shown in figure 2A, the first end (1.3.1) is coupled to the first winch (1.1), while at the second end (1.3.2) there are first gripping means (1.3.3), for example, a clamp or jaw or carabiner, which are coupled to the upper handle (C.1) of the suitcase (C).

[0181] The first moving means (1.1), or first winch (1.1), is coupled and fixed to the second side (2.1.2.2) of the door (2.1.2).

[0182] On the other hand, the loading system (1) also comprises two second movement means (1.2), configured by means of two second winches (1.2), and two second cables (1.4) with a first end (1.4.1) and a second end (1.4.2) each. The arrangement of the first (1.1) and second (1.2) winches with the first (1.3) and second (1.4) cables is symmetrical with respect to the longitudinal direction Z-Z', or vertical direction, as shown in the present figure in a two-dimensional manner, which means that, in a three-dimensional manner, the arrangement of the first (1.1) and second (1.2) winches with the first (1.3) and second (1.4) cables is symmetrical with respect to the plane formed by the longitudinal direction Z-Z' and the first transverse direction X-X', that is, with respect to the plane ZX. As shown in Figure 2A, the first ends (1.4.1) of each second cable (1.4) are coupled respectively to one of the second winches (1.2), while at the second ends (1.4.2) of each second cable (1.4) there are, respectively, second gripping means (1.4.3), for example, a clamp or jaw, which are respectively coupled to one of the side handles (C.2) of the suitcase (C).

[0183] The second moving means (1.2), or second winches (1.2), are, respectively, coupled and fixed to the second surface (2.1.1.2) and the third surface (2.1.1.3) of the trunk (2.1) in a symmetrical manner.

[0184] Likewise, Figure 2A shows stage a) of the method for introducing a suitcase (C) into the interior space (2.1.1) of the trunk (2.1) of the vehicle (2), where the first (1.3.3) and second (1.4.3) gripping means are coupled to the load (C), or suitcase (C), with the door (2.1.2) of the trunk (2.1) of the vehicle (2) open.

[0185] Additionally, Figure 2A also shows the position of the load (C), or suitcase (C), in which step d) of the method of extracting a suitcase (C) from the interior space (2.1.1) of the trunk (2.1) towards the outside of the vehicle (2) would be carried out.

[0186] Additionally, Figure 2B shows the same vehicle (2) and the same loading system (1) as in Figure 2A.

[0187] Likewise, Figure 2B shows step d) of the method for introducing a suitcase (C) into the interior space (2.1.1) of the trunk (2.1) of the vehicle (2), where the load (C), or suitcase (C), has been positioned on the fourth surface (2.1.1.4) of said interior space (2.1.1). Steps e) and f) of said method for introducing a suitcase (C) are not shown in the present figures.

[0188] As shown, the first cable (1.3) has been unwound from the first winch (1.1), while the second cables (1.4) have been wound onto each of the second winches (1.2), such that the suitcase (C) is in the position closest to the second winches (1.2) and centered within the interior space (2.1.1) of the trunk (2.1). Figure 2B also shows the suitcase (C) after performing step a) of the method for extracting a suitcase (C), said suitcase (C) being positioned inside the trunk (2.1) of the vehicle for extraction towards the outside of the vehicle (2).

[0189] Figure 2C shows a third embodiment of a loading system (1) for positioning a load (C) inside the trunk (2.1), installed in a vehicle (2) with the indicated characteristics. In this way, the loading system (1) allows both inserting and removing a suitcase (C), with a first upper grip point (C.1) and two second grip points (C.2) located on the surface opposite the first grip point (C.1), that is, two second lower grip points (C.2), in the interior space (2.1.1) of the trunk (2.1) of the vehicle (2).

[0190] As shown in this figure, a first upper grip point (C.1) is the upper handle (C.1) of the suitcase (C), and the second grip points (C.2) are two lower handles (C.2) of the suitcase (C).

[0191] In this way, the configuration of the loading system (1) in this case comprises first movement means (1.1), where the first movement means (1.1) comprise two pulleys, fixed to the second wall (2.1.2.2) of the door (2.1.2) of the trunk (2.1), two pulleys fixed on the second surface (2.1.1.2) of the trunk (2.1) and on the third surface (2.1.1.3) of the trunk (2.1) and two winches, fixed to the fourth surface (2.1.1.4) of the trunk (2.1).

[0192] Likewise, the loading system (1) comprises second movement means (1.2), where the second movement means (1.2) comprise two pulleys, fixed on the second surface (2.1.1.2) of the trunk (2.1) and on the third surface (2.1.1.3) of the trunk (2.1), and two winches, fixed to the fourth surface (2.1.1.4) of the trunk (2.1).

[0193] As can be seen in Figure 2C, a first cable (1.3) extends from the first upper grip point (C.1) of the load (C) to one of the pulleys (1.1) of the first movement means (1.1) located on the second wall (2.1.2.2) of the door (2.1.2) of the trunk (2.1), and then extends to another of the pulleys (1.1) of the first movement means (1.1), located either on the second surface (2.1.1.2) or on the third surface (2.1.1.3) of the trunk (2.1) and reaching one of the winches (1.1) of the first movement means (1.1).

[0194] Likewise, a second cable (1.4) extends from each second lower grip point (C.2) of the load (C) to one of the pulleys (1.2) of the second movement means (1.2) and then to one of the winches (1.2) of said second movement means (1.2).

[0195] As shown in Figure 2C in a two-dimensional manner, the arrangement of the first displacement means (1.1) and the second displacement means (1.2) is symmetrical with respect to the longitudinal direction Z-Z', which means that, in a three-dimensional manner, the arrangement is symmetrical with respect to the plane formed by the longitudinal direction Z-Z' and the first transverse direction X-X', that is, with respect to the plane ZX.

[0196] Figures 3A - 3C show, respectively, a perspective of a particular embodiment of support means (1.5) of a loading system (1) as shown in Figures 2A and 2B, and a profile and elevation view of a particular embodiment of a vehicle (2) according to the second inventive aspect with the support means (1.5) of Figure 3A.

[0197] In this way, Figure 3A shows support means (1.5) with respect to a longitudinal direction Z-Z', or vertical direction, and with respect to a first transverse direction X-X' and a second transverse direction Y-Y', which configure a horizontal plane according to the orientation of the present figure.

[0198] The support means (1.5) are configured by a first support (1.5.1) extending along the second transverse direction Y-Y', and comprising a first end (1.5.1.1) and a second end (1.5.1.2), to each of which the following elements are coupled: a second support (1.5.2), extending in an oblique direction to the longitudinal direction Z-Z', and a third support (1.5.3), extending along the longitudinal direction Z-Z'.

[0199] Each of the third supports (1.5.3) comprises, at the end opposite to the end fixed to the first support (1.5.1), support means (1.5.3.1) configured according to a circular base.

[0200] Likewise, Figure 3A shows first movement means (1.1), or first winch (1.1), located at the midpoint of the first support (1.5.1), and two second movement means (1.2), or second winches (1.2), each located at the end opposite the end fixed to the first support (1.5.1) of each second support (1.5.2).

[0201] As already indicated, figures 3B and 3C show, respectively, a profile and elevation view of a vehicle (2) according to the second inventive aspect with support means (1.5), in the case of figure 3C support means (1.5) like those shown in figure 3A.

[0202] Thus, Figure 3C shows a vehicle (2) comprising a trunk (2.1) with an interior space (2.1.1) and a door (2.1.2) in a first position, or open position, extending mainly along the first X-X' and second Y-Y' (not shown) transverse directions, that is, it extends horizontally, and in a second position, or closed position, mainly along the longitudinal direction Z-Z', that is, vertically.

[0203] The door (2.1.2) in turn comprises a first face (2.1.2.1), located on the outside of the vehicle (2) both in the open position and in the closed position of said door (2.1.2), and a second face (2.1.2.2) located on the inside of the vehicle (2) when the door (2.1.2) is in the second position (closed position).
