    The suitcase-bag with lifting scales, is a traveling load tool, or, transport of objects, formed by two concentric boxes (2, 3). The inner box (3) has, at each end, an edge (4) that rests on the end of the long radius of two lifting scales (5, 6), -installed between the bases of the two boxes (2, 3) -, formed by an oval (15) with three pivots (11-13). The pivot (13) functions as fulcrum of the lever (5, 6). The central axis (12) of the oval (15) functions as the fulcrum of the lever that is formed between the two pivots (11, 13). Two axes (8, 9) that rise to a plate (10) located at the base of the inner box (3) rise vertically from them. From the short radius (6) of the other lever (5, 6) another vertical axis (7) rises which will also reach the plate (10). (Machine-translation by Google Translate, not legally binding)

    DESCRIPTION
    Suitcase-bag with lifting scales.
    Object of the invention
    The main objective of the present invention is to reduce the weight of the objects (14) that a user can transport in a suitcase-bag like the one presented, which can be achieved with lifting scales (5-9) located Between the two boxes, exterior (2) and interior (3) that form this suitcase-bag that will push up when its levers feel the weight that pushes them down.
    Background of the invention
    The main antecedent of my invention of the day (20.03.17) is found in the lever principle of Arqulmedes, from which, on this occasion, a system capable of redirecting the weight is formed, when this weight pushes down the ends of the long radius (5) of the first lever (5-9).
    Description of the invention
    The suitcase-bag with lifting scales is an object transport tool (14) that is formed by two boxes, one outside (2), and another box (3) that is inserted inside. The inner box (3) has, at the ends of the base, two edges (4) protruding downwards. In the gap between the two outer and inner boxes (2, 3), - that is, between the two bases of the two boxes (2,3) -, two lifting scales (5-9) are placed facing each other. The ends of their long radii (5) are located below the two edges (4) and in contact with them. These long spokes (5) will pivot on a pivot (13) that will be located at one end of the diameter of a bakelite oval (15). The other pieces described for these lifting scales (5-9) will also be made of bakelite. From the central axis (12) of this oval (15), on its two faces, two vertical axes (8) are raised, which are fixed with screws on a plate (10), which is placed horizontally below the base of the inner box (3). From the end of the short radius (6) of the first lever (5, 6), another axis (7) is folded vertically, which will be in contact with the plate (10) without being fixed thereto. On the other side of the diameter of the central axis (12) of the oval (15), there is another pivot (11), located as close as possible to the central axis (12). From it rises another vertical axis (9), which comes into contact, also, with the plate (10). Actually, two long radii (5) will be placed parallel on each of the two oval (15), one on each side of it. And, there will also be two vertical axes (9), and two central vertical axes (8) on each side of the oval (15), and, on the two oval (15).

Below the inner box (3), the two lifting scales (5-9) that will reduce weight to the load of objects (14) are placed when pushing up when the two edges (4) of the ends of the inner box (3) push down, depending on the amount of objects (14) inside it, at the end of the long radius (5) of the first lever (5-6).

    Description of a preferred embodiment
    The suitcase-bag with lifting scales, is characterized by being a useful travel load, or, for the transport of objects purchased in the supermarket, which is formed by two concentric boxes (2, 3). The inner box (3) has, at each end, an edge (4) that rests on the end of the long radius of two lifting scales (5, 6), - installed between the bases of the two boxes (2, 3) -, formed by an oval (15) that has three pivots (11 -13) in its horizontal diameter. The pivot (13) functions as a fulcrum of the lever (5, 6), while the central axis (12) of the oval (15), functions as a fulcrum of the second lever that forms between the two pivots (11, 13) . From these pivots (11-13), two axes (8, 9) are raised vertically that reach a plate (10) located at the base of the inner box (3). From the short radius (6) of the other lever (5, 6) rises another vertical axis (7) that will also reach the plate (10). The operation is simple to explain, because it is about redirecting upwards the force of the weight of the objects (14) that are introduced in the inner box (3), this weight that is directed downwards. To achieve this redirection, we will use two levers: the first lever (5, 6), and. the one formed between the pivots (11, 13) on the same oval diameter (15). The downward force that the pivot (13) will receive when the weight of the objects (14) lowers the edges (4) of the base of the inner box (3), will also push down the vertical axes ( 8) of the central axis (12). However, this downward force will be compensated by an upward force, such as that received by the vertical axes (9) for being at the other end of the oval diameter (15), which forms a second lever (11 -13) and a pair of forces in the oval (15) between the pivots (11) and (13). Therefore, the upward force that the vertical axis (7) will feel will not be compensated with another downward force, and all of it will be used to subtract the weight of the objects (14) that we have placed inside the inner box (3). Moreover, as the short radius (6) of the first lever (5, 6) is much shorter than its long radius (5), the force of the weight of the edges (4) will increase in proportion to these measures, which You can check with the Arqulmedes equation:
    image 1
    And, the same will happen in the second lever (11-13), because, the pivot (11) we will have put it, by way of example, two centimeters of the central axis (12), while the pivot (13) we will have moved ten centimeters away from the central axis (12). If we now reapply the same Arqulmedes equation for this second lever (11-13), we will obtain that the upward force of the vertical axis (9) will be greater than the downward force that the vertical axis (8) of the central axis will feel (12) as a consequence of the downward force imposed by the pivot (13) of the first lever (5, 6). In this way, we obtain a double gain of upward force, with respect to the force of the weight of the objects (14) that is directed downwards, with which, the effort that the user will have to make to transport this weight, - when transport the
    suitcase-bag taken by its handle (1) -, it will be minimal, and, the painful task of dragging clothes on a trip, or, to take food from the remote supermarket, to the family home, will become a simple walk.
