    DESCRIPTION

    Foldable or retractable rolling track for use in mobile car transporter structures, mobile car transporter structure equipped with said rail.
     5
    Field of the Invention

    The present invention has as its object a folding or retractable lane used in the movement of vehicles to a storage or transport position of a vehicle transport or evacuation platform from said position, said lane 10 being normally located on both sides of a vehicle transport structure in minus a portion of the length of said structure.

    The car transporter structure is normally a lifting structure formed by two longitudinal beams or trusses arranged one on each side of a transport vehicle; This elevable structure 15 may be provided with fixed, simple, longitudinal and angular movable carrier platforms in the structure, comprising a support for the wheels of a single axle of a transported vehicle, or multiple, comprising supports for two or more axles of the vehicles transported, and the latter with fixed distance between the supports of the axles of the vehicles transported or with variable distance between said supports by means of the extension / retraction of the support. These mobile structures are located in transport vehicles, such as trucks, semi-trailers or trailers, rail cars, or transport containers, among others.

    The lane can adopt an unfolded position in which the vehicle can roll on said lane and its geometric plane cannot be crossed by another vehicle or another load, or a folded position in which the space corresponding to said lane is released, allowing that a certain additional space is available to be occupied by a vehicle or other cargo, maximizing the possibility of approximation between vehicles which will allow in many cases to carry at least one additional vehicle, and also maximizing transport efficiency. 30

    Optionally the rail can be extensible / retractable.

    Background of the invention
     35
    Mobile platforms to perform different actions are widely known and used in many industrial applications. An example can be the lifting platforms, moved by hydraulic cylinders or mechanical methods, and that integrated into a truck serve to introduce or remove any type of cargo from it.
     40
    These prior art platforms are not designed to be integrated into a system of elevated structures for the transport of vehicles, to which the object of the present invention is applied. The current car transporter structures are designed in such a way that they integrate a lane or fixed area where vehicles can roll to carry out loading and unloading maneuvers. Due to the fact that the rails are fixed (they are part of the structure), it is not possible for them to be removed when their use is not necessary.

    Platforms are known for vehicles that are articulated with respect to their front end, which allows vehicles to roll along said platform until reaching a transport position, the rear end (loading / unloading) of said platform being able to be raised once arranged the vehicle in said transport position and making accessible the use of the corresponding platform arranged in the lower part of the transport vehicle Any of these platforms comprises a fixed base or fixed rails with respect to said
    platform, which requires certain space requirements that limit proximity to which the vehicles must be placed with each other.

    Autotransporters are especially used in the transport of cars, by trucks or trailers, or by rail, and one of the objectives pursued is to maximize transport efficiency, being an important factor the volume of occupation of the platform.

    This part has developed mobile platforms for the transport of vehicles that are arranged on a lifting structure formed by two beams or side trusses, which have the limitation that they must be supported on a fixed base for the placement of vehicles on them, in that space optimization takes place by not having raceways, requiring that said mobile platform rest on the fixed platform of the transport vehicle so that the transported vehicle can be placed on said mobile platform. Said mobile platforms can be moved and / or tilted to allow the loading of other vehicles or other goods in the lower part, and thus achieve a greater degree of packaging.

    Description of the invention
     twenty
    The present invention relates to a folding or retractable lane with respect to a car transporter platform (which we will summarize as foldable in the following) or a lifting structure carrying car transporter platforms, said lane being the one used as a rolling base in vehicle placement in car transporter platforms, which solves several problems in the face of the platform systems known and / or currently used.

    The foldable rail of the invention allows vehicles to roll on said rails when they are in the deployed position, normally during loading and unloading operations, allowing said rails to be folded once the vehicles have been placed in the corresponding 30 positions in the respective platforms, fixed or preferably mobile.

    It is of particular application in articulated mobile platforms, although it is also applicable to fixed platforms or non-articulated mobile platforms. The foldable rail of the invention allows said mobile platforms to be provided with a raceway that will be used in the 35 phases of loading and unloading of the vehicles, phase in which it is not necessary to occupy the space occupied by them, and which will be folded once the vehicle is moored to said platform, thus allowing to increase the available space and / or the approach between vehicles.

    The present invention provides greater versatility to the transport vehicles provided with 40 platforms for transporting vehicles, since it allows carrying out loading and unloading maneuvers at any height, without the need for mobile platforms to be supported on a fixed base, and Once the maneuver has been carried out, they can be folded, for example, by means of a hydraulic actuator operated by the driver himself, leaving, as has been said, the space for loading, being possible to adjust the distance between vehicles located at 45 different levels.

    Since the platforms are substantially symmetrical with respect to a longitudinal vertical plane (with respect to the fixed platform or chassis of the transport vehicle), usually the raceways will also be arranged symmetrically with respect to the same plane, in the deployed position. In a first embodiment, the folding rails are articulated in the trusses or beams that form the carrier structure of the car transporter platforms; in a second embodiment the rails are part of each vehicle carrier platform and
    they are articulated on the respective outer lateral edges of each vehicle carrier platform.

    Optionally, each lane will be formed by sections, the sections that form being articulated with each other relative to a longitudinal axis. 5

    Optionally, each rail or section of the rail can be extensible / retractable, formed by at least two parallel non-coplanar sections, but very close to each other capable of relative longitudinal sliding. You can have guides and / or bearings that facilitate the extension / retraction operation. This option will be convenient when the platform is also extensible / retractable to adapt to vehicles with different wheelbase.

    According to other possible embodiments of the invention, the raceway can be articulated on only one side of the platform or asymmetrically. fifteen

    Normally, but not necessarily, said treads will be made of sheet steel.

    Preferably, the rails will be folded by the bottom of the platform or of the platform structure.

    When some maneuver must be carried out in which the vehicles have to roll on the platforms, the raceways are deployed, normally operated by hydraulic actuators or manually, so that they are located just below the transport platform or the platform holder structure; the vehicles are loaded or unloaded and the raceways are folded, usually by means of the hydraulic actuator or manually, placing them in an upright position, preferably below the platform platform or the side edges of the transport platform, thus leaving the space between vehicles completely cleared to make the approximation between the same 30.

    According to a particular embodiment of the invention, the folding raceway is installed in the vehicle carrier platform itself. It consists of at least two equal systems hinged one on each side of the platform, in the longitudinal beams that form the 35 frames of the platform. Preferably, on each side the rail is formed by two flat sections hinged together, which allows the rail to fold approximately in half to occupy the minimum space. Inside or below these sections, telescopically sliding there are two other sections, in this way it is possible to cover the entire hollow space of the vehicle carrier platform. These sections are moved manually or automatically, by means of a system of guides to facilitate their extension, so that when they reach their point of maximum extension, a socket is made using a bolt, fixing their position, preventing their displacement, and maximizing their resistance . When they are to be collected, the procedure is reversed, leaving the sections located vertically on one side of the vehicle transport platform, so that they do not interfere with the approach maneuvers.

    Detailed description of the preferred embodiments

    As described above, the invention relates to a folding raceway, for use in platform carriers and / or in vehicle loading platforms. Particularly, but not limited to, the foldable raceway of the invention is applied to 5 mobile vehicle loading platforms (3), which can be tilted and / or moved longitudinally and / or displaced in height with respect to a corresponding platform structure.

    A first embodiment according to the present invention is shown in Figures 1 and 2. 10 According to this embodiment, the carrier vehicle is provided with at least one carrier structure of at least two mobile carrier platforms (3), said structure being elevable with respect to the base platform or the carrier vehicle chassis, by means of longitudinal beams located one a each side of the platform (5) and at the same height. These mobile transporter platforms can be moved longitudinally by carriages (6) 15 to be placed in the proper position. When the platforms are simple, or what is the same as what supports the wheels of a single axle, the position will also allow to adapt to the wheelbase of the transported vehicle. In the case of multiple platforms, that is to say carriers of at least two axles, the distance between the wheel supports corresponding to the different axles of the transported vehicle will normally be adjusted telescopically 20 by means of a hydraulic drive. Under these mobile platforms at least one raceway (1,2) is located on each side of the vehicle's cargo area. These rails (1,2) extend totally or partially along each side of the loading area. Each of the lanes may constitute a single section or be formed by successive sections, linked together or being independent. The rails (1, 2) will normally be made of sheet steel. The use of such material is ideal for its high strength and low price. However, any other material that has sufficient strength could be equally used.

    According to this embodiment, the rails (1,2) of each of the sides are located symmetrically with respect to a longitudinal central plane, to each of the sides of the platform carrier structure (5), and particularly said rails are provided with a hinge / s or means of articulation (4) with said structure (5) carrying the mobile platforms. This articulation (4) allows the rails (1,2) to be turned from an unfolded position, in which the vehicles can roll on them, particularly in loading and unloading operations 35, and a folded or retracted, vertical position.

    Thus, the platform carrier structure is provided with carriages (6) with manual or motorized actuation, for example, by means of hydraulic cylinders, which move the vehicle transporter platforms. In this way, the loaded vehicles can roll until their wheels 40 are supported on said supports, at which time, if the platform carrier structure is sufficiently elevated, the rails (1,2) can be folded to their retracted position. These carriages (6) can be moved and fixed along a travel guide in the platform carrier structure, in fixed positions or in any position along the route. Four. Five

    The folding of the rails (1,2) is preferably carried out by automatic means; particularly, the actuation is carried out by means of hydraulic actuators (8), with the support of the hydraulic cylinder jointly and severally attached to the platform-holder structure (5) while the rod support is jointly and severally connected to the raceway that will move in each case.

    The following operations are carried out to carry out the loading maneuver of the vehicles:

     the platform carrier structure (5) is placed at the desired height, and the vehicle transporter platforms (3) are located in the desired positions

     the hydraulic actuators (8) are operated so that they raise the rails (1,2), at least one on each side of the loading area, which normally rises 5 simultaneously

     When the actuator reaches its maximum stroke, the rails (1,2) are located in a parallel plane and inferior to the transport platforms (3), attached to said platforms; 10

     This way you can carry out the loading process without any risk.

     Once the vehicles are loaded, these rolling structures are folded, again activating the hydraulic actuators (8) until the zero stroke of the 15 rod, thus folding the structures without interfering in the area destined for loading, being able to carry out the Approach maneuvers between vehicles, obtaining maximum use of space.

     Finally, the lower levels are loaded with the maximum available space for loading and maneuvering 20

    This configuration is especially advantageous, because it is possible to obtain the functionality of being able to roll at any height and of being able to make large approximations between the vehicles, in a totally automatic way and adding very few structural elements to the means of transport. Therefore, this configuration manages to obtain a versatile system without reducing load capacity or space.

    A second embodiment of the folding rail of the invention is shown in Figures 4 to 8. 30

    In this case, each mobile vehicle transport platform is supported by the platform carrier structure, and is made up of pairs of support frames for the wheels of the vehicles transported, and each platform is independent from other platforms, so that a different platform for each vehicle. These mobile platforms 35 can be fixed or extensible, and can have means of inclination, elevation, or longitudinal displacement and are supported by a central axis.

    According to this embodiment, the platforms (3) are formed by longitudinal beams (9,10) and transverse frames supporting the wheels of the transported vehicle. If the 40 platforms (3) are extensible, they will also comprise longitudinal beams (11,12) of the corresponding extensible portion, so that the beams on each side (9,11; 10,12) allow a parallel or telescopic movement, whose drive can be manual or automatic, for example, by means of a hydraulic actuator.
     Four. Five
    Between the sides of the rear frame and the rear support frame of the wheels of the transported vehicle, folding rails are arranged on each side.

    According to a preferred option, the raceway on each side is divided into at least two sections, an outer section (13) and an inner section (15), which means that it is divided into at least two halves by a longitudinal division in which an articulation means (16) is located between them, which allows the rotation between both sections with respect to a longitudinal axis.
    The inner section will be provided at its front and rear inner ends with a guide rod (21) that will be supported by corresponding guides of the front and rear transverse frames. The outer section will also be articulated to the corresponding longitudinal beam (11,12) of the vehicle carrier platform. The displacement that must be made of the sections that make up the guide rail can thus be carried out effortlessly, the 5 rods having a single degree of freedom in horizontal linear movement, and supporting from that position the guide rail, whatever its position .

    Thus, when a rail is in a folded position, the two sections that form it will be arranged parallel and vertically, almost under the corresponding beam. In the deployed position, 10 will adopt a horizontal coplanar position, just below the anterior and posterior frames.

    In the case of extendable mobile platforms, it is provided that each of the inner and outer sections of the raceway in turn comprise an extensible portion with its corresponding outer (17) and inner (19) sections. As described above, the outer (17) and inner (19) sections are provided with an articulation means (20) with each other, and the outer section (17) is also articulated to the longitudinal beam of the extensible portion of the platform (3).
     twenty
    In this way it is achieved that the extension of the car transporter platform as of the rails is carried out simultaneously acting as a single element. In addition, since the rails are hinged in the middle, they occupy half of the space when folded with respect to a lane without central hinges.
     25
    In use, the raceways are initially folded and placed in a vertical position below the longitudinal beams, in a plane parallel to the longitudinal vertical central plane of the vehicle carrier platform. When the loading maneuver is to be carried out, the raceways are manually or automatically deployed, a maneuver facilitated by the guide system, which leads to the different bands that make them up to their fully extended position. In this position they are fixed manually by means of a pin, or automatically, being coplanarly located between them and parallel to the car transporter platform and with a clearance between the two millimeters, as can be seen in Figure 4.
     35
    Once the vehicles are loaded on the car transporter platforms, the rails are folded, removing the pin that holds them and moving them manually or automatically to the initial position, being again in an upright position under the frames that form the car transporter platform or under the beams of the platform structure, and in this position the relevant approach maneuvers between vehicles are carried out, not interfering with said lanes at all when taking advantage of the available space.

    Even though the invention has been described for an ideal substantially symmetrical embodiment, it is understood that within its scope of protection variants of embodiment such as the fact that the rails are asymmetrical, or the combination of the characteristics of the different embodiments, or, in In the case of vehicles or platforms with lateral loading systems, the inversion of the concepts of longitudinality or transversality, and in general, any non-essential variation that solves the problem posed in an equivalent way.

    Obviously, the invention extends to a vehicle carrier platform that includes the lane 50 described.
