    [0002]
    [0003]
    [0004] OBJECT OF THE INVENTION
    [0005]
    [0006] It is an object of the present invention, as the title of the invention establishes, a carriage with folding support structure, carriage means any device that is provided with a support structure, provided with wheels and on which it is mounted a basket, where the carriage support structure, can be folded over the carriage under certain conditions.
    [0007]
    [0008] The present invention characterizes the special configuration and design of each and every one of the parts that are part of the carriage, so that it allows the folding of the carriage support structure on the basket, which results in a series of practical advantages for its use.
    [0009]
    [0010] Therefore, the present invention is within the scope of transport carts provided with a rolling structure on which a basket is attached.
    [0011]
    [0012] BACKGROUND OF THE INVENTION
    [0013]
    [0014] In general, the transport carts comprise a rolling structure on which a basket united in solidarity is arranged, forming a single whole, so that when a series of products are transported in a transport car and they want to be transferred to a vehicle, For example, it is necessary to remove all products from inside the basket and deposit them in the trunk or storage place of a vehicle.
    [0015]
    [0016] In general, families when they buy in large stores use these transport cars, and during the purchase process they go depositing the items inside the basket. When they leave the large area they proceed to transfer the products contained inside the basket to the trunk of the vehicle and when they arrive at their home, in general, they usually pass the products back to a new car. These situations also occur in the transport of goods from one storage center to another.
    [0017]
    [0018] Therefore, in order to avoid a continuous transfer of goods from the car to a vehicle, and from the vehicle back to a storage location, one possibility would be to be able to transport the car directly, however this situation is not possible because the basket is attached to the structure and the volume of the set does not fit in a trunk, in addition to not having a means of load transfer, the whole car is a weight impossible to lift by a person.
    [0019]
    [0020] To solve these difficulties, different solutions have been developed such as those described below:
    [0021]
    [0022] FR 2925448 This design lacks a load transfer mechanism and therefore forces the user to start folding with the structure loaded.
    [0023] On the other hand, the design does not take into account the reduced space under the car and the folding must be started when the basket is not very advanced inside the trunk.
    [0024]
    [0025] These 2 aspects of the design involve poor ergonomics and safety risks for the user.
    [0026]
    [0027] ES2317142. In this patent a set is disclosed in which there is no security for the user. In fact, in the operation of loading and unloading the operator will have to bear the entire weight of the basket.
    [0028] EP-00670008. This patent discloses a design that does not have a load transfer mechanism and therefore folding is not very ergonomic and may pose a risk for the user.
    [0029]
    [0030] US6024527, discloses a set in which the structure is not linked to the basket and therefore requires a little ergonomic handling to load the basket in the trunk. In addition, this design requires a complex mechanism with many parts generating many maintenance tasks and possibilities of mechanical failure.
    [0031]
    [0032] FR3038292 discloses a structure that is not linked to the basket and therefore has a bad ergonomics to load the structure in the trunk.
    [0033]
    [0034] All the solutions that are known in the state of the art do not satisfactorily solve the problem posed, presenting complex partial solutions and without security for the user.
    [0035]
    [0036] Therefore, it is the object of the present invention to overcome the mentioned drawbacks of lack of ergonomics, safety and complexity in manufacturing, by developing a carriage with a folding support structure on the basket such as the one described below and collected in its essentiality in the first claim.
    [0037]
    [0038] DESCRIPTION OF THE INVENTION
    [0039]
    [0040] The object of the present invention is a carriage provided with a folding base structure with respect to the assembly formed by a basket and its support structure, for which this last set is vertically movable with respect to the base structure.
    [0041] The base structure is a rolling structure, generally it will count, but it is not limiting, with four support points formed by wheels, which some of them can be swivel.
    [0042]
    [0043] The car also has a means of transferring cargo from the basket to the structure or to a support surface, such as the floor of a trunk, for which, the loading means can have any means that produces a lift and lowering of the assembly formed by the support structure of the basket and the basket itself with respect to the base structure.
    [0044]
    [0045] Also, to be able to produce the folding of the base structure with respect to the basket, the latter is provided with guiding means through which the base structure runs once the load has been transferred to a surface, such as the surface of a trunk , freeing the base structure from the weight of the whole support structure and its basket.
    [0046]
    [0047] Due to the degree of freedom that the basket presents with respect to the support structure, when the basket is supported by the support structure, it has fastening means, which in a preferred embodiment can be a screw or threaded rod actuated by a protruding knob , which tightly presses and sets the position of the basket with respect to the support structure.
    [0048]
    [0049] The base structure can be adjusted in height in a complementary manner in order to adapt to different heights of the boot and the like.
    [0050]
    [0051] The material used in manufacturing can be any of those known, preferably Aluminum due to its structural rigidity and low weight.
    [0052]
    [0053] Thanks to the characteristics described, the following effects are achieved.
    [0054] - The load transfer mechanism is simple and usable in an ergonomic and easy way.
    [0055] - The means of folding the base structure and guiding it with respect to the assembly formed by the support and basket structure are simple in its manufacture and use.
    [0056] - At all times the safety of the user is maintained, the whole of the support structure and the basket itself being always supported either on the surface of a boot or on the base structure, there is no risk to the user.
    [0057]
    [0058] Unless otherwise indicated, all technical and scientific elements used herein have the meaning normally understood by a person skilled in the art to which this invention pertains. In the practice of the present invention methods and materials similar or equivalent to those described herein can be used.
    [0059]

    [0063]
    [0064] To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical implementation thereof, a set of drawings is attached as an integral part of said description. where, for illustrative and non-limiting purposes, the following has been represented.
    [0065]
    [0066] In Figure 1, we can see a perspective representation of the car object of the invention.
    [0067] In Figure 2, we can see a more precise detail of the load transfer mechanism.
    [0068]
    [0069] Figure 3 shows another different perspective view where other construction details can be seen.
    [0070]
    [0071] Figure 4 shows the folding sequence of the assembly of the base structure and the support structure on the carriage basket.
    [0072]
    [0073] PREFERRED EMBODIMENT OF THE INVENTION.
    [0074]
    [0075] In view of the figures, a preferred embodiment of the proposed invention is described below.
    [0076]
    [0077] In Figure 1 we can see that the car with folding support structure comprises:
    [0078] - A rolling base structure (1),
    [0079] - A support structure (3) of a basket (2), where this support structure (3) is supported on the base structure and is vertically movable with respect to the base structure (1).
    [0080] - Means for transferring the load (4) from the basket (2) either to a support surface or to the base structure (1).
    [0081] - Guiding means (7) of the folding of the base structure on the basket (2).
    [0082]
    [0083] The base structure (1), is a rolling structure that is preferably supported on four support points provided with wheels (5), and which, optionally, can be adjusted in height in order to adjust to different heights of the trunk of a vehicle.
    [0084]
    [0085] In Figure 2 it can be seen that the support structure (3) of the basket (2), in the embodiment shown comprises:
    [0086] - - A front bar (11) two vertical tubular elements (12) fixed at the ends of the front bar (11) and vertically movable with respect to the base structure (1)
    [0087] - two lateral arms (6) in transverse arrangement with respect to the front bar (11) and attached to the vertical tubular elements (12)
    [0088] - Rolling elements fixed by the inner side of the lateral arms (6) and running through the guiding means (7), which in a possible embodiment can be an axis.
    [0089]
    [0090] The guiding means (7) in the embodiment shown consist of a "C" shaped guide laterally attached on each side of the basket, so that when the basket is supported on the floor of a trunk, the base structure can be folded (1) on the basket (2).
    [0091]
    [0092] The means for transferring the load (4) (figure 1), consist of means that raise and lower the whole of the support structure (3) and the basket itself (2) with respect to the base structure (1) and in the embodiment shown they consist of a pivot (8) provided with a helical groove (9) through which a bar driven by a crank (10) slides.
    [0093]
    [0094] Said crank (10) when acting produces the lifting or lowering of the support structure assembly (3) and the basket itself (2) with respect to the base structure (1). Thus, this action, which allows the base (14) (figure 3) of the basket (2) to rest on the floor of a trunk, at which point the base structure (1) stops receiving the effort of the weight of the basket (2) the base structure being released to be able to swing it with respect to the basket by guiding it through the guiding means (7).
    [0095]
    [0096] Also, in figure 3 it is worth noting how the basket is fixed with respect to the support structure (3), which is by means of knobs (15) provided with threaded rods that cross the lateral arms (6) of the structure of support (3) fix said arms on the basket (2).
    [0097] In figure 4 in the different stages A), B), C) and D) the folding process of the assembly formed by the base structure (1) and support structure (3) on the basket can be observed. In scene A) the load transfer takes place, leaving the basket to rest on the support structure and resting on the surface of the trunk or the like. In scene B) the set of base structure (1) and support (3) have rotated 90 ° with respect to their original position, while in scenes C) and D) there is an advance of the set of the base structure ( 1) and support structure (3) along the guiding means (7) by its upper horizontal section, until all the elements are perfectly coupled in a reduced volume.
    [0098]
    [0099] Describing sufficiently the nature of the present invention, as well as the manner of putting it into practice, it is stated that, within its essentiality, it may be implemented in other embodiments that differ in detail from that indicated by way of example. , and which will also achieve the protection sought, provided that it does not alter, change or modify its fundamental principle.
