    [0004] Object of the invention
    [0005] The present invention refers to a hoe whose object is to provide a new configuration that improves the connection between the parts that constitute it, the handle and the head, at the same time that it provides greater strength and greater resistance to wear and tear during use.
    [0007] Background of the invention
    [0008] Currently, most of the hoes consist of two elements, handle and hoe head, which are joined by taper.
    [0010] That is, the handle is cylindrical and in the lower part it widens, generating a positive conical area (increases the diameter) while the head is equipped with a conical hole in which the handle fits, so that when inserting the conical part of the handle in the conical hole of the head, together with the weight of the hoe head, a pressure is generated that blocks both parts, holding them together.
    [0012] Usually the handle is made of wood, which determines that the aforementioned joint varies depending on the humidity of the wood, since when the handle dries or begins to deteriorate, the hoe head does not have a useful friction surface on handle and begins to rotate or comes off the handle.
    [0014] Users usually try to solve this problem by re-moistening the handle by putting it in water, adding rags between the two parts, lag screws and wedge-like screws, which still do not provide a good grip between the two elements, so it is not possible to work and they also run the risk of being injured.
    [0016] Description of the invention
    [0017] The object of the present description is based on a hoe, whose configuration and design solve the problems mentioned in the state of the art.
    [0019] The invention, like the hoes of the state of the art, comprises a handle and a head, which is equipped with a hole through which the handle is coupled and fixed, and presents as its main novelty, the fact that it is characterized by comprising an intermediate piece that is arranged between the handle and the hole of the head, such that said intermediate piece presses against the handle and against the hole in the head, fixing the head to the handle. Furthermore, the intermediate piece is provided with at least one projection, which is configured to be housed in a recess provided in the hole of the head, so that the head is attached to the handle in such a way as to avoid the possibility of the head can move both in longitudinal direction and in angular direction on the handle.
    [0021] In the preferred embodiment of the invention, the hole in the head and the intermediate piece have a complementary, frusto-conical configuration, which facilitates the fixation of the head on the handle, but could well adopt any other configuration that allows the fixation of the head. on the handle by the pressure exerted by the intermediate piece on the hole of the head and the handle. The frusto-conical configuration makes it easier to avoid longitudinal displacement between the handle and the head once the joint has been made.
    [0023] In one embodiment of the invention, the projection of the intermediate piece and the recess of the hole in the head of the hoe, have a triangular prismatic configuration, which also facilitates the fixation of the head on the handle and avoids the possibility of turning the hoe. head on the handle.
    [0025] In the preferred embodiment, the intermediate piece is provided with a pair of projections, preferably facing each other and arranged on the longitudinal axis of the handle, so that in the same way the head hole includes a pair of recesses, in which they are housed. the projections of the intermediate piece.
    [0027] It has been envisaged that the handle can be made of plastic, wood or both, but it could also be made of any other material from those provided in the state of the art.
    [0029] The intermediate piece is preferably made of plastic, so that its use does not alter its properties, which allows the fixation between the handle and the head of the hoe to be maintained over time.
    [0030] In one embodiment, the intermediate piece is fixed on the handle by over-injection, but it is also envisaged that it can be manufactured independently and is then inserted into the lower end of the handle as a thimble, for which the frusto-conical configuration of the intermediate piece is closed by one of its bases to couple it to the end of the handle on which the head is attached.
    [0032] Description of the figures
    [0033] To complete the description and in order to help a better understanding of the characteristics of the invention, this specification is accompanied, as an integral part thereof, by a set of figures in which, with an illustrative and non-limiting nature, it has been represented the next:
    [0035] Figure 1 shows an exploded perspective view of an embodiment of the invention.
    [0036] Figure 2 shows a perspective view of the hoe of the previous figure, in which the handle has been partially represented and the head is in an intermediate position prior to its fixation on the handle.
    [0037] Figure 3 shows a perspective view equivalent to the previous figure, but in this case the head is arranged in the final fixing position.
    [0039] Preferred embodiment of the invention
    [0040] The invention comprises a handle 1 and a head 2 that are joined by means of an intermediate piece 3, for which the head 2 is provided with a hole 4, through which the handle 1 is inserted. Between the handle 1 and the hole 4 of the head 2, the intermediate piece 3 is arranged, so that said intermediate piece presses against the surface of the handle 1 and the hole 4 of the head 2, which establishes the fixation of the head 2 on the handle 1 .
    [0042] The head 2 and the intermediate piece 3 have a frusto-conical configuration, so that the fixation of the head 2 on the handle 1 is facilitated by means of the intermediate piece 3, avoiding that once said fixation is made, longitudinal displacement between the head 2 and handle 1. The frusto-conical configuration of the intermediate piece 3 is preferably closed by its lower base, wrapping the lower end of the handle 1 to favor its positioning and retention, as will be discussed later.
    [0043] Furthermore, the intermediate piece 3 is provided with at least one projection 5 that has a configuration complementary to that of a recess 6 made in the hole 4 of the head 2, to allow the projection 5 to be housed in the recess 6, in such a way which prevents the head 2 from rotating around the handle 1. In the preferred embodiment, the incorporation of two projections 5 and two recesses 6 is provided, arranged facing each other on the longitudinal axis of the handle 1, which favors the fixation of the head 2 to the handle 1 and prevents said head 2 from rotating around the handle 1, thus preventing the problems existing in the state of the art already discussed from occurring.
    [0045] In the exemplary embodiment, the projections 5 and recesses 6 have a triangular prismatic configuration intended to facilitate the coupling between the intermediate piece 3 and the head 2, at the same time that it prevents the head 2 from rotating around the handle 1.
    [0047] Therefore, the described configuration prevents both longitudinal and angular displacement between the head 2 and the handle 1 from occurring.
    [0049] The intermediate piece 3 is made of plastic, so that when the hoe is used, its properties are not altered, maintaining the fixation between the handle 1 and the hoe head 2 over time.
    [0051] The intermediate piece 3 can be fixed on the handle 1 by over-injection, but it can also be manufactured independently, like a thimble, and then inserted on the end of the handle 1, so that in any of the cases the fixing function is performed. from the head 2 to the handle 1 without it being able to move both longitudinally and angularly on the handle 1.
    [0053] In the exemplary embodiment, the handle 1 has, near its end, a step that defines an end zone 1a with a smaller diameter, in which the intermediate piece 3 is arranged, so that its outer surface is flush with the outer surface of the handle. 1, the intermediate piece being perfectly integrated into the handle 1.
