    5 OBJECT OF THE INVENTION
    The present invention relates to a cane, which incorporates a clamp at its lower end to be able to collect objects from the ground. that clamp being operated from a lever located in proximity and / or in correspondence with the handle of the rod itself.
    The object of the invention is to provide a cane with the aforementioned characteristics but in which the actuation of the collection clamp is carried out through a cylinder located between the actuation lever and the arm to which the clamp belongs.
    15 BACKGROUND OF THE INVENTION
    Different types of support rods with object pick-up pliers are known, such as those set out in French patent FR 2342679, US patent 3425734, German utility model DE2020111 00801 U, among others, so that in all cases the
    20 clamp is formed by an arcuate section that emerges laterally through the hollow body of the cane, with the possibility of tilting to open or close, so that this element is linked to a spring that works by traction, and that at its other end is it relates to a rod linked to a tilting lever provided in proximity to the handle or upper crosshead of the cane. Therefore, in all these cases there is a direct relationship between the manual operating lever and the rod, as well as between it and the spring that works under tension and, between said spring and the
    5 element that acts as a clamp, so that the transmission of efforts between such elements usually leads to failures in the operation of the device, due to possible gaps between parts, to which must be added the high number of joints and relative displacements between such elements described.
    DESCRIPTION OF THE INVENTION
    The rod that is recommended, incorporating a clamp, a spring and a drive lever, has the particularity that the element acting on the clamp is an independent cylinder, 15 which at its upper end is located under the internal end of the lever of actuation, so that the tilting of this one carries with it the thrust of the cylinder and the displacement of this one produces the incidence, also by pushing, of the corresponding arm of the lever, making act towards an opening position of this by tilting of said arm lever, against a spring, which works under compression, and tends to keep the clamp in constant closing position 20, so that it only opens when the manual actuation lever is operated.
    This new structural conception with regard to the way of actuation of the clamp, prevents possible malfunctions, since it is based on a cylinder that moves tightly in the bosom of the cane, independently of the lever mechanism and the clamp, so that between these elements no joints or fixing elements of
    5 no type, acting between them by simple thrust, which guarantees a much simpler, effective and efficient operation.
    In a variant embodiment, the lever is located below the handle or crosshead of the cane and is operated by the index finger of the hand, while in another alternative of realization, the lever is located in correspondence with the upper-anterior part of the handle itself, to be actuated by pushing through the thumb of the hand that holds the cane.
    in any case, the tilting of the lever, downwards or upwards, carries, by means of the corresponding appendix or rocker associated with said lever, the thrust in
    15 downward direction of the cylinder and with it the thrust of the lower end of such a cylinder on the corresponding arm of the lever, swinging it to carry out its opening against the tension of a spring which, as previously stated It works under compression.
    According to another feature of the invention, it is provided that the hook, materialized
    20 mounted on an initially straight element, in the area of its joint, and which at its free extremity has a curved section, said limb is finished off in a kind of harpoon, which facilitates
    Pick-up maneuvers for the cane.
    Also noteworthy is the fact that the cane has a kind of flexible tongue in correspondence with the area of the handle or next to it that allows it to be attached to a belt, when it is not necessary.

    PREFERRED EMBODIMENT OF THE INVENTION
    As can be seen in the figures outlined, and in relation specifically to Figure 1, the bas
    Tone of the invention is constituted, as is conventional, from a hollow body (1) that can be of any appropriate material, be it wood, metal, etc., and in any case endowed as is also conventional with corresponding handle or upper crosshead (2), and inferiorly of a support bead (3).
    15 The cane has at its lower end a clamp (4) formed by a tilting element, provided with a straight section (4 ') that is flush with the cane body inoperative situation, and is articulated at a point (5) to said cane body, having a lever arm
    (8) which allows its tilting, from the inoperative position (figure 1) to the operational position (figure 2).
    Said clamp is topped by its free end in a harpoon species (13), which facilitates maneuvering.
    Object collection bras.
    The clamp (4) is required to the closed position by means of a spring (6) anchored between the lever arm (8) and an internal fixed point (7), working under compression.
    5 The operation of the clamp (4) is carried out by means of an axially movable cylinder (9) within the hollow body of the cane, and which at its lower end rests on the lever arm
    (8) where the clamp articulation is established, while at the upper end said cylinder (9) faces by means of an appendix, to the end (10) of a manually operated lever (11), as a rocker, with its corresponding joint (12) located below the
    10 handle (2) of the cane (t).
    According to these characteristics, when pulling the lever (11) with the index finger that corresponds to the hand holding the cane, through its handlebar or crosshead (2), the lever (11), swings around the point of articulation (12) causing its inner end (10) to swing
    15 down, which produces the downward thrust of the cylinder (9), which in turn affects the elbowed and upper section (8) of the element (4 ') of the clamp (4), so that this assembly tilt and open said clamp (4), as shown in figure 2.
    When the lever (11) stops working, the spring (6) pushes the lever arm (8) upwards causing the clamp to close automatically.
    In a variant embodiment, the one shown in figure 3, the lever (11 '), with its articulation (12') instead of being located below the handle (2) or crosshead of the cane, are located in correspondence with the upper-anterior part of said handle, in which case the actuation of such a lever (11 ') instead of being performed with the index finger, by traction, is performed by pushing on it of the corresponding thumb to the hand holding the crosshead or handlebar
    5 (2 ') of the cane (1), a push that will carry, as in the previous case, the thrust and downward movement of the cylindrical body (9') acting in the same way to carry out the opening of the clamp. Figure 4 is another variant in which the cylinder (9) is pushed directly by its upper button-shaped finish (15)
    Figure 5 shows that the cane in its side view has a hook (16) to hang it, for example, on the user's belt when its use is not required.
